Preface
CENTERIS – Conference on ENTERprise Information Systems is an international conference
addressing the largely multidisciplinary field embraced by the Enterprise Information Systems (EIS),
from the social, organizational and technological perspectives.
The CENTERIS’2011 edition, focused on aligning technology, organizations and people, was held
in Vilamoura, Algarve, Portugal. This was the place where, from 5 to 7 October 2011, under the
leitmotiv of Enterprise Information Systems, academics, scientists, information
technologies/information systems professionals, managers and solution providers from all over the
world had the opportunity to share experiences, bring new ideas, debate issues, introduce the latest
developments, from the social, organizational and technological perspectives.
More than 180 manuscripts were submitted to CENTERIS, coming from all over the world.
There were about 120 papers selected for presentation and inclusion in the conference proceedings.
The selected papers represent more than 350 authors from academe, research institutions and industry,
representing near 30 countries.
These proceedings are intended for use by academics and practitioners that want to be aware of
what is currently in the EIS agenda, from research to everyday business practice. We believe that the
high quality and interest of the contributions received in CENTERIS’2011 edition makes this an
important book in EIS field.
Finally, on behalf of the organization, we would like to express our gratitude to all the authors, for
their visions and excellent contributions to the conference, as well as to the scientific committee
members, who accede to share their insights, prompt collaboration and constructive comments in the
review process. We are also grateful to all who accede to contribute to CENTERIS, some of them with
high quality manuscripts, but unfortunately, due to several constraints could not have seen their work
accepted for presentation and publication.
Please enjoy your reading!

Organizing a conference is a very hard but compensating and enriching experience, as it involves a
complex set of different activities, from the design of the conference, the establishment of the scientific
commission, contacts with authors, organization of the review process, discussion and exchange of
ideas and experiences, process management, organization and integration of contents, and many other,
with the permanent objective of preparing an event that meets the participants expectations. And this
task cannot be accomplished without a great help and support from many sources. As conference cochairs,
we would like to acknowledge the help, support and believe of all who made possible the
creation of CENTERIS.
We are grateful to all the authors who have chosen CENTERIS’2011 to present their work, thank
you, you made the conference happen! Our gratitude goes also to all the authors that submitted their
proposals but were not able to see their work accepted, due to several constraints.
The Scientific Committee of CENTERIS integrates 95 individualities, most of them who shared
their knowledge and gave their constructive comments indispensable to the decision-making associated
with the selection process, to whom we express our gratitude.
The conference sponsors played a very relevant role. We are grateful to IPCA, UTAD, ESTG -
IPLeiria, GESITI network and to the scientific journals who offered the chance to publish enhanced
versions of selected papers: the Information Resources Management Journal (IRMJ), the Journal of
Theorectical and Applied Electronic Commerce Research (JTAER), the International Journal of
Human Capital and Information Technology Professionals (IJHCITP) and Information and
Communication Technologies for the Advanced Enterprise: an international journal (ICT'ae).
Finally a word of appreciation is due to the members of the organizing committee for their prompt
and friendly support.

Extended abstract
Defining objectives is of capital importance for the good performance of an organization. These
objectives must be set at all levels and be significant to keep alignment with its vision, focused in its
goals, and therefore, committed to its success. Defining objectives must follow rigorous requirements
that guarantee relevance and accomplishment and must be set at the Strategic, Operational and Tactical
levels.
The research objective was to identify the organizational elements and related theories (objectives
writing rules, organization structure, objective hierarchy, objective management concept) which need
to be taken into account to define consistent objectives, to align them between the organization levels
and finally, to group the set of relevant concepts in the form of a model that could consider two level
(strategic and operational) taking in consideration: strategic goals, priorities, organizational units,
business processes and key factors.
The Model allows to evaluate if an objective is relevant, and to elaborate the Action Plan which will
guarantee its accomplishment. Then the organizational units of the next level (operational), will be able
to establish their objectives (second level objectives) according to the Action Plan developed. The
steps to be followed to define objectives using the model are: i) ensure that the objective contributes to
the organization’s priorities; ii) verify if the objective is in harmony with the organization’s goals; iii)
determine HOW to achieve the objective, establishing which processes will be used and specifying
what has to be done across each one; iv) determine WHO is responsible for its achievement,
establishing which organizational units will intervene and their relationship with the previously
determined processes; v) establish what will be the implications of the objective in the organizational
key-factors, what modifications will have to be made in each one to achieve the objective; vi) assign an
indicator to the objective to control its achievement.
The Model proved to be an essential tool for the strategic level plan and was used to establish the
Organization Management Objectives for 2011.

Extended abstract
Two-sided platforms are successful business models, overall for industries highly demanding
integrated systems as it is the case in the computer games, software development, and internet-based
companies. We analyze well known cases of this wave to understand the way they work to accomplish
blockbuster models in their industries that later are replied for their competitors. Likewise we will pay
special attention to other companies that are implementing these strategies in their businesses
revolutionizing their industries and taking advantage of their competitors.
User innovation is an excellent proposal for companies that want to compete in their markets in a
strategy based on innovation. Two sided-platform markets are the way to implement this strategy in the
companies. We can stand out many well known cases of companies based in two-sided platforms. For
instance, in the last two years the case of iPhone or Firefox, both of them achieves a very important
share of their respective markets.
Nowadays, new cases are coming up in other industries and they establish the way that the rest of
the competitors will follow.
Saab Automobile is one of these cases providing access to more than 500 signals from different
sensors in the vehicle to develop specific Android applications integrating vehicle data and Android
OS capabilities. Likewise, the Swedish brand cars try to be distinguished from its competitors thru and
infotainment system unique in the car industry.
Another industry that is using two-sided platforms to promote the innovation is the payments
market. Cases like Paypal or Amazon Payments have already attracted the attention of management
literature. Nevertheless, in the last two years has come out a new one competitor that is revolutionizing
the payment industry IP Commerce, more than two others. IP Commerce is a standard platform for
multiple rails (cloud-based computing). The way to work is similar to Windows OS enabling the users
to install different kind of peripheral devices without having to install drivers for each one. In the case
of IP Commerce tied up with payments system.

Extended abstract
In 2010, a flexible and dynamic Model of the Effort Regime (ER) - “EX-ANTE and EX-POST Model
Development and Monitoring of the Portuguese Air Force Effort Regime” was established
comprehending the following phases: Planning, Proposal & Approval, Execution, Control and
Analysis. The “Analysis Phase” (AP) has the objective of identifying deviations between planning and
execution of its the different components. Due to the constant need to adapt the Organization to the
surrounding context, a study was conducted to establish AP applicability, identify the target
Components, the Key Performance Indicators (KPI) and other related elements.
The research had the objective of identifying, within the AP context, different key-vectors (mission,
aircraft and crews - called the Operational Triad) and their relation to the essential dimensions
(operational, logistical, personnel and financial) of the Portuguese Air Force (PoAF) operational
product. Mission serves as a guideline in the formulation of strategies and action plans. Aircrafts and
Crews are vital to Mission completion.
Using Organizational Engineering (OE) principles, a Meta-Model was created with resource to
Business Inteligence techniques aiming at complementing the ER EX-ANTE and EX-POST Model,
increasing flexibility and the Organization’s level of Self-Awareness and Situational-Awareness,
which translates into majoring organizational adaptability and, therefore, the capability of rapid
reaction to external adverse events.
The research highlighted the relationships and interactions between each key vector and the
essential dimensions. Finally, characteristics relevant to each Model component analysis were
characterized and the relevant KPI identified.
PoAF’s ER AP Model was instantiated from the Meta-Model relating the Operational Triad with the
four essential organizational dimensions. Each Model component was organized according to the
origin of the information source type (primitive or derivative). Model applicability and validation was
carried out using ER 2010 real data within the operational scenario. The collected information was
presented in Excel® Spreadsheets, by means of an Analysis Table. The results were compiled into a
staff headquarters report and were thoroughly used in the 2011 ER planning and execution control.
The research resulted in a Model that has already proven its applicability and that mainly helped to
constitute a tool to collect, store, analyze and provide access to data resulting in better information and
better decision making support. Using 2010 data to Model validation proved its utility and highlighted
the need to joint venture the academic and the operational dimensions in studying and providing
solutions to relevant complex problems that affect the Portuguese Air Force.

Extended abstract
Over the last years several theoretical models have been proposed to explain the innovation adoption
process, each one using different approaches [1-2]. Therefore, various mathematical models, based on
simple expressions have been developed to describe the diffusion of an innovation among a given
potential adopters set. Today, these models are a fundamental tool to predict the innovation adoption
growth. Several examples can be found in literature, as the Gompertz and Bass macro-logistics models
[3], among many others.
The application of these models is made accordingly to the estimation of certain coefficients. These
coefficients are typically estimated from time series. However, in several problems there is not any
historical data, which constitutes a serious drawback in applying this type of methods. Thus, to
simulate the process sometimes is necessary to use features of other similar innovations [3, 4]. This
could introduce some entropy in the process. Moreover, the models based on the logistic equation have
a limited application. On the other hand, modeling at macro level is inaccurate because it assumes a
perfect social mix where everyone interacts with everyone and does not measure whether the
interpersonal are the same [4]. Other type of models has been proposed, based on the study of the
individual and / or organization within a social system [5-6]. Some approaches consider that the
diffusion is made through the influence of social network. In this case, the influence is transmitted by
direct contact between individuals [4,7]. For instance, Young [7] proposed and built a model based on
a graph.
Taking the former work in consideration, particularly the Young model [7], and evolutionary
computation [8], this work proposes a new model using evolutionary algorithms to describe the
innovation adoption process. Moreover, the proposed model under development is based in Roger,
Valente and Davis models concepts [5,4,9] and Young interaction network [7]. The main advantage of
a model with these features is that historical data is not required to simulate the innovation diffusion,
since its construction is focused on the individual characteristics, in their behavior towards innovation,
external influences (media) and their interpersonal relationships. Moreover, it only requires taking into
account the individual adoption trends and social systems (businesses, schools, municipalities, etc.)
converted into mathematical models, as well as the network of direct contacts between individuals. The
predisposition of an individual to adopt a particular innovation can also be evaluated probabilistically.

Nowadays we assist to a great proliferation of online communications, namely Online Word-Of-Mouth
(OWOM) like comments and opinions. Marketing managers need to know the polarity (positive and
negative) and intensity of these comments, Sentiment Analysis (SA), as well as to acknowledge the
influence of the consumer communities’ collective opinion on other consumers’ choice. Many studies
have shown that OWOM affects positively the company returns. This is why marketers want to
monitor and to influence OWOM. Opinion Mining (OM) uses natural language processing (NLP)
methods to study the opinions, sentiments and emotions expressed in texts. There are at least 20-30
companies that offer OM services in USA, while OM services are in an embryonic state in Portugal.
We will present a brief analysis of current SA tools that will help the development of a Portuguese SA
tool. “Listening the Voice of the Customer Solutions” can be classified in four groups: a) Search
engine and media monitoring offerings - SE&MM; b) Text-analytics software companies - TAS; c)
Full-service listening platform vendors - FSLP and d) Private branded communities - PBC. Although
in media monitoring offerings (SE&MM) sentiment analysis could be present, it is particularly in TAS
and also in FLSP that this analysis is common.
In this brief review we focus in TAS highlighting some proprietary brands (integrated suite of
customer analytics): Attensity, Clarabridge, Sentiment Metrics, Sentimetrix, Synthesio and Summize.
All of them process SA based in NLP. Only Attensity and Synthesio make explicit that apply to the
Portuguese language in addition to others that are identified. Clarabridge operates with any language
and Sentiment Metrics and Summize do not mention the language. The scales for SA are diverse:
Sentimetrix is the only to use a continuous scale (-1 to +1); rating scales are utilized by Summize and
Clarabrige (-5 to +5) and Synthesio, Sentiment Metrics and Attensity employed rank scales. These
brands are developed for multiple industries (e.g., hospitality, retail banking, healthcare, automotive
and agriculture) but Summize is the most restricted (music, movies, books and others). When
comparing the information sources exploited, Sentiment Metrics (news sites and social media such as
Facebook and Twitter) and Summize (conversation on Twitter, prototypes-blogs and reviews)
discriminate less than the others brands – Clarabridge covers customer feedback, regardless of channel
and structured and unstructured data. Open source solutions, falling within the TAS, generally are not
integrated solutions and usually have a narrower industry scope and languages’ coverage. The
capabilities of analysis and reporting are reduced or inexistent. Some reference brands are GATE,
Yale/RapidMiner, UIMA, LingPipe and Balie.

With the emergence of platforms associated with the concept of Web 2.0, which enables users to view,
create and distribute content. The user-generated content in online communities, which keeps growing,
is a valuable source of information for both community users and business industry associated with
this type of platforms, as hotel industry [1, 2], where user-generated content, in the form of reviews is
extremely important, since 74% of tourists use other users reviews to make their choices [2]. Another
reason that justifies the in-depth study of the impact of this user-generated contents in the hotel
industry is the fact that 34.7% of the money spent online is in the hotel industry which is
approximately $10 billion [1, 2].
Given the importance of such platforms in the hotel industry, it is of great importance to study this
type of platforms to try to unveil the factors through the evaluations and comments that lead customers
to book a hotel but not the other, or why suddenly the hotel sales starts growing, due for instance to the
traditional and well-known concept “word-of-mouth” gains a much bigger dimension on the web due
in result to the exposure to millions of users [3].
Former studies, proved the influence of user-generated contents in the decision making of other
users [1, 3], on the number of hotel bookings and in the hotel management regarding the services
provided to clients [2, 4]. In line with the preceding studies, this study will analyse the relationship
between the score and reviews given by clients on the Booking online platform, in order to confirm,
the influence of factors identified in previous studies and of new ones that might influence user
decision making, which will be useful for hotel managers to enhance online sales. The Booking online
platform was chosen due to its dimension and use in previous studies[5], which enables us to compare
our findings.

Extended abstract
Despite being a relatively recent activity in Portugal, Internal Auditor (IA) is increasing its importance,
and companies are aware that Internal Audit is essential in today's world business because it helps
companies on task simplification and cost reduction [1].
Audit is the systematic process to obtain and evaluating objectively evidences about the
correspondence between information, situations or procedures and established criteria [1] and to
perform this process, the auditor must work in a phased manner [2], thru several activities and
processes in a systematic, thorough and automated way and that’s why auditors look for tools and
computer techniques [3].
The available IT tools that support the Internal Auditor’s (IA) activities are very complex when
compared with Portuguese business’s reality. These IT tools are focused on the Internal Audit’s
process and not on the Auditor’s daily work.
This poster shows the evidences for the opportunity to create a tool to support the IA’s work,
allowing him to plan and execute the audit in a simple mode, based on a particular procedure,
providing in each procedure’s point to know which questions need answer, which data is needed, who
is involved, when is the data/responses needed and what indicators are associated with each step.
According to a study in 2008, Portugal has the highest increase in audit activity [4]. This growth allied
with the dissemination of IT/IS in business demonstrates the usability of implementing an application
in this area. Upon this work’s conclusion it is expected to have developed an application to support the
IA’s activities, which will allow the management of the audit process supported in organization
procedures, with focus on the Portuguese reality of Small and Medium Enterprises (SMEs).

Today, organizations have multiple alternatives to acquire the Information Technology/Information
Systems (IT/IS) services they require, and can choose between a high degree of insourcing up to largescale
outsourcing [1], seen as a pillar of modern management and economics practice, has grown
dramatically in recent years, so much that it is no longer the exception and is quickly
becoming the rule [2]. Although several studies point out the advantages of IT/IS services outsourcing
within organizations [3-5], they do not refer the levels of efficiency/performance of IT departments of
the organizations that recur to outsourcing in comparison with ones that do not.
In order to evaluate the performance of IT departments we propose the development of a model
using the Data Envelopment Analysis (DEA) method [6-7]. Several studies of benchmarking practices
using DEA have identified numerous sources of inefficiency in some of the most profitable
organizations.
The main goal is to compare the levels of efficiency depending on the type level sourcing that IT
department’s use. The built model will evaluate IT departments according to a set of global indicators,
which replace the more restrictive character of each factor’s levels of productivity. Among the various
techniques that analyses the performance, the Data Envelopment Analysis has great acceptance, both
among researchers and in respect of applications to real problems. DEA is a nonparametric approach
based on linear programming to evaluate the relative efficiency of organizational units, called Decision
Making Units (DMUs), characterized by "consumption" of multiple inputs (e.g., the number of IT/SI
employees, the response time of IT Help Desk), to "production" of multiple outputs (e.g., the number
of end users, satisfaction index of end users) [8].

Extended abstract
Every business process is based on business rules, which are provided by their own management
manuals. It is important for an organization such as the Portuguese Air Force to collect the required
capabilities from the existing business rules in order to be able to face the surrounding environment,
adapt to changes and to be provided the correct guidance for its business processes, which are
developed according to its mission. Aiming to achieve the optimum output at the executing level,
which would in turn boost the processes’ efficiency and, therefore, allow the organization to achieve
its goals while resorting to a diminishing budget, it is critical to maintain a correct alignment between
its business rules.
Three military publications were analyzed in this research, the Operational Concept, the Weapons
Systems’ Logistics Concept and the Employment Concept. The first manual corresponds to the
strategic layer of command and the last two are positioned at the tactic level.
The Operational Concept determines what governance mechanisms should be present in each
manual and also specifies that every publication must include personnel, intelligence, operational,
logistics and support (PIOLA) information which should, in turn, from an operational point of view,
focus on characterizing each weapons system and defining their essential elements while taking into
consideration their associated governance mechanisms and establishing the correct way to deploy
them. These concepts should also define the operation, mission and operational tasks for each weapons
system.
This study produced a Concept Verification Matrix through which it is possible to demonstrate the
alignment between any set of business rules manuals in terms of PIOLA concepts and a matrix that
adapts the Concept Verification Matrix to a Transversal Business Rules Matrix.
This last matrix provides for a unique interpretation and execution of all the organization’s business
processes through a correct definition of business rules for each high level business process in
accordance with an adequate alignment for what is determined for each area of business.
A partial alignment was found between the analyzed manuals as none of the business rules defined
by the subordinate publications were opposite to those the main publication predicted. However these
manuals were not constructed as defined, chapter wise, nor approached all the governance mechanisms
and PIOLA concepts determined by the Operational Concept. It was also determined that any changes
in a specific business rule in a particular manual would press for the other manuals to also be altered.

Project management continues to present several problems, concerning time, budget, and scope.
Therefore, it is important to study practical cases in this area, aiming at identifying the practices and
techniques used for successful goals achievements.
Visabeira Digital is a member-company of the Visabeira Group and it operates in the area of
software development. This company has a long-standing experience and offers a wide range of
services. Dedicated to software development and retailing, it provides technical assistance and training
as well as Internet access, e-mailing, contents, data processing, hosting, multimedia, surveillance, and
control services. Based in Viseu, Portugal, the company has extended its operations in five other
countries and reached an annual turnover of approximately 6.000.000,00€. With a personnel of over
100 employees, Visabeira Digital has obtained the ISO9001, ISO14001 and OHSAS 18001
certifications.
Within the last three years, the company was involved in about 20 projects of software
development, each with a running time of 9 months and with a maximum budget of 100.000,00€. Out
of these 20 projects, 18 were custom software development, one was ERP implementation, and another
with ERP and custom software development characteristics. A brief scrutiny indicates that 18 of these
projects were concluded in time, 15 respected the budget restrictions and all of them complied with the
specified objective. In this work, we shall describe the main practices implemented in the development
of these projects.
The following procedures and guiding principles were always used in the afore-mentioned projects:
- Defining the project plan;
- Defining the project deliverables;
- Defining the costumers’ expectations;
- Determining the priorities in accordance with customers’ expectations;
- Involving the customers in the definition and substantiation of the scope of the project;
- Formulating the detailed list of necessary steps for the accomplishment of all project
objectives;
- Establishing the project main schedule according to contractual time-requirements;
- Concluding a time-based analysis upon detection of errors/deviations, presenting
subsequent solutions and launching corrective actions;
- Reporting every deviation to the client (if the case);
- Estimating the costs for all necessary resources;
- Identifying all necessary resources (teams, equipment and materials);
14

- Defining clear objectives and responsibilities for each team member;
- Setting-up the team’s priorities;
- Outlining activities that observe the standards of quality;
- Monitoring the results for quality control;
- Standardizing the project documentation;
- Categorizing the models and documents which were to be applied to all projects;
- Management of a project documentation pool, systematic and accessible to the elements
of the project team;
- Implementing of metrics definition for quality measurement;
- Producing the documentation for the project results;
- Identifying the goods to be purchased and the services to be subcontracted;
- Making a purchasing plan;
- Building a request plan;
- Performing a thorough analysis of conditions and costs for each supplier;
- Producing and managing the legal documentation and contracts.
In these projects, the Gantt charts were the techniques employed for project timelines. Experience
with similar projects was the approach used in order to accurately estimate the duration of the
activities. ROI was used for project costs’ evaluation. The project information was distributed to the
project stakeholders in meetings and using a web page. The lessons learned were always preserved and
then exploited when a new project started.
For this company, the key factors identified for the successful management of a project were the
following: Involvement of top management; Involvement of the customer throughout the process;
Objectives and project requirements clearly defined; Performance of technical tasks; Commitment of
the team in achieving the objectives; Efficiency of project manager.
Among the procedures analyzed in all these projects, some were recurrent in each and every project,
thus testifying for their effectiveness and significance. A special emphasis should be given to one
group of such recurrent procedures: the quality management. In the case of Visabeira Digital, much of
the company’s success relies on the proper employment of quality management, as a main area in the
development of its business.

Extended abstract
Projects have an unpopular reputation of failure, especially software projects [1]. Every year, billions
of dollars are loss due to these failures [2]. Project’s failures may involve a high waste of material and
intangible resources (e.g. monetary, motivation, and deterioration of company brand). Taking on
account the current global economic environment, these consequences may cause a huge and
irreversible impact in organizations.
The poor attention given to the Risk Management (RM) throughout the project life cycle is one of
the problems identified in the literature [1, 3]. RM aims to decrease the impact of negative events and
identify positive opportunities. The Project Management Body of Knowledge (PMBoK) defines the six
processes of RM [4]: (1) Risk Management planning; (2) Risks identification; (3) Qualitative Risk
Analysis; (4) Quantitative Risk Analysis; (5) Risk response planning; (6) Monitoring and Control of
Risk.
Although RM is identified as a critical issue, it is still not well valued by project managers [3]. This
reality justifies the development of new models and tools to allow conducting an efficient risk
management.
Some aspects of RM have received high attention in the literature, as is the case of the Risk
identification process [1]. However, the current methodologies are very dependent on the projects
stakeholders’ sensibility and risk perception. In software projects this issue is amplified, because of the
many variables that must be considered like, for instance, the need to deal with new technologies or
with new knowledge areas [5].
Simulation can represent an interesting approach to analyze and explore the impact of the risks. The
risks can be imitated through a model that allows the analysis and exploration of new hypotheses
without compromising the real system [6]. For instance, it would be useful a simulation to enable not
only a better risk identification, but also to enable analyze how the combination of risks can lead to
new risks (combined or singular). Moreover, the simulation would also help to get a better
understanding how the risks evolve over time.

Accounting and management students need to practice the knowledge acquired during the course, so
that in future possess the critical and analytical skills to use in real situations to frame them with
accounting and tax standards learned. With the e-Government tools dissemination and their access to
certified professionals only, accounting and management students’ loss the opportunity to interact with
the these tools used by companies to comply with fiscal and other obligations (e.g. social security). In
order to overcome this difficulty and provide students with the necessary skills, surged the idea of
using simulation in the classroom, like the military, which use flight simulators to train soldiers [1].
Simulation has proved to be an excellent technique in different areas, such as military, management,
medicine and education [2, 3]. With simulation it is possible to analyze and explore new hypotheses
through an imitation of a real system without real consequences [1, 2, 4]. In this sense, seems to be a
very interesting approach the creation of simulators that mimic the real e-Government tools in order to
allow students to explore the different possibilities of using them without real consequences.
In this paper we propose the development of a web-based IRS simulator, which mimics the real IRS
e-Government tool, to enable students to simulate the IRS delivery. It will have some of the IRS forms,
which will be validated according to existing Portuguese tax law. This simulator will be used and
tested by accounting and management students of Coimbra Institute of Accounting and
Administration.

Extended abstract
A Virtual Reality model was created in order to help in the maintenance of exterior closures and
interior finishes of walls in a building. It allows the visual and interactive transmission of information
related to the physical behavior of the elements, defined as a function of the time variable. To this end,
the basic knowledge of material most often used in walls, anomaly surveillance, techniques of
rehabilitation, and inspection planning were studied. This information was included in a data base that
supports the periodic inspection needed in a program of preventive maintenance. The results are
obtained interactively and visualized in the virtual environment itself. This work brings an innovative
contribution to the field of maintenance supported by emergent technology.
The most frequent anomalies that occur in the coated façades were analysed in order to create a data
base linked to the virtual model that could support planning of inspections and maintenance strategies
in buildings. The database contains the identification of anomalies that can be found in each type of
material used in façades and the corresponding probable cause. For each kind of anomaly the most
adequate repair solutions are also selected and included in the data base. Thus, the virtual model gives
users the ability to transmit, visually and interactively, information related to the closure properties of
exterior walls, allows them to analyse the anomalies observed in an inspection of the real building and
to predict the corresponding repair work. The 3D virtual model can be seen, therefore, as an important
tool for anomaly surveillance in structures and for supporting decision-making based on the visual
analysis of alternative repair solutions.
For each new building to be monitored the characteristics of the environment (exposure to rain and
sea) and the identification of each element of the façades must be defined. The data associated to each
element are the building orientation, the type of exterior wall (double or single), and the area and type
of coating. Once each monitored element has been characterized, several inspection reports can be
defined and recorded and thereafter consulted when needed. In an inspection visit to the local, using
the drop-down menus allowed by the interface, the user can associate the characteristics of the
observed anomaly to: a façade element; the type of anomaly, the specification, details and the probable
cause of the anomaly, an adequate repair solution and pictures taken in the building. After completing
all fields relating to an anomaly, the user can present the report as a pdf file. With this application the
user may fully interact with the program referring to the virtual model at any stage of the maintenance
process and analyze the best solution for repair work. It can also support the planning of maintenance
strategies.

Extended abstract
By way of introduction it should be noted that studies belonging to health sciences field have a
character essentially practical, and in this sense, the Nursing is established as a practical discipline in
which clinical cases are used to assess the students’ knowledge, skills and competencies. Systematic
construction constitutes one of the greatest challenges in elearning.
As the clinical cases must show cases of people in different health situations, the manual
construction of cases is highly expensive to generate a sufficient number of assumptions and that is
why there is the following hypothesis (H1): The automatic simulation of clinical cases is possible
through the use of Expert Systems.
The simulation of practical cases in Health Sciences, specifically in nursing, can be done
automatically by describing three items:
Basic Conditioning Factors (FCB): define vulnerability to suffer from care as described in D.
Orem ‘General Theory of Self-Care Deficit’ and takes place in ‘Definition and weighting of
the populations most vulnerable to professional care requirements: welfare hardship index
based on basic conditioning factors’.
Active health problems: act as selectors for certain services portfolio in particular for aspects
of group health education or care for people with chronic diseases.
Key fields (necessary for the presence of a specific diagnosis): act as selectors care diagnoses
and their criteria of outcomes and interventions. Examples of this element, we cannot state the
diagnosis of ‘Caregiver Role Strain’ without considering whether the person cares for
someone. These fields can be found in the ‘Diagnostic Guide nurse (2.0)’ published by the
Centre for Nursing Methodology (OME).
For the automatic construction of assumptions has PBc2 platform (Platform Based on Care
Knowledge) developed by the Department of Computer Science at the University of Alcala in
collaboration with the Department of Nursing at the same university and the Department of
Methodology and Innovation.
20

This platform allows to carry out the description of FCB, by generating as can be seen a clinical
report from the FCB of the individual. It has created a table in Excel format that allows the selection of
active health problems in the person and key fields, thus ending the description of the three elements of
a clinical case.
As a result the combinatorial possibilities for the FCB reach 885,735 cases, increasing exponentially
when including the active health problems in the person and ‘key fields’.
In conclusion, we can say that the development of applications that allow the simulation of clinical
scenarios in health sciences increases the variability of them, being an object very useful in teaching
and learning.

Abstract provides short information about some results of the research realized in the Czech Republic
hospitals. The aim of the research was to find how the information systems support necessary process
management. The research was focused on a narrow group of information systems designed for the use
in medical facilities. These systems are used by the management and medical staff as a sophisticated
auxiliary tool and could be also used as a support of management decision, internal cooperation and
knowledge sharing in various medical facilities. Data were collected through a structured interview in
40 hospitals. Preliminary results indicate that 85% of healthcare facilities use some form of
information systems. The ratio between hospitals using commercial information system, commercially
delivered system and specially developed IS is nearly balanced. Especially in health care services there
is a problem with the need to implement many of the specific information system modules and
processes.
Absence of modules supporting process management is caused by the specific requirements of the
medical industry. There is a need to coordinate the legal standards, EU regulations and requirements of
confidential data maintenance and also the needs of connections with the necessary metrics to meet
ISO standards implemented in healthcare facilities. The survey also shows that ICT solutions
supporting process management are usually individually solved (in-house). We also find the
deficiencies in the process of knowledge sharing; it means that the necessary communication is solved
via e-mail or corporate mailboxes. This cannot be considered completely effective and also there is a
real possibility of information loss or delay in information flow.
The requirements of hospitals show that for the actual needs of process management it would be
appropriate to own a specific module, which could arrange records enabling to plan and evaluate the
processes, monitor disagreements and coordinate them with a corrective and preventive action. In
practice it should primarily include:
Audit plan
This means an overview of all internal audits with the necessary metadata, such as status, date of
occurrence, auditors, etc. Audits can be internal and external. Audits may be accompanied by given
tasks to other employees.
Incidents
In case an incident (disagreement) is found, it will be recorded to a list. An integral part of the list is
a field which to determines which audit the occurred incident belongs. So there are the relations
visible.
22

Precautions
If an incident is detected, an appropriate precaution needs to be created (so-called Corrective
Precautions). Furthermore, there are preventive precautions that are not allocated to any error.
However, the link between an incident and the resulting precaution is needed for clarity of the system.
The findings of this research identified a lack of support for the modular components of commercial IT
systems suitable for healthcare industry. If a medical facility has information system, it usually does
not have all the necessary modules suitable for cooperation, communication and process management.
Only a small percentage of the respondents possess this module. These facilities own a module which
was created specifically for their needs and belongs to the information system developed also
specifically for these medical facilities.
We suggest creating a knowledge network during implementation of process management in
hospitals. In this knowledge work processes we apply the concept of maturity model. This “Capability
Maturity Model” (CMM) was developed for software organizations by the Software Engineering
Institute of Carnegie-Mellon University between 1986 and 1993. This concept of process maturity (5
levels of processes: ad hoc, defined, repeatable, managed, optimized) migrated to a measure of
organizational process maturity. As a communication tool could be used the intranet or some types of
wiki systems.
In the near future the authors plan that the results of the survey will be correlated with the data
obtained in foreign medical facilities in EU. Next step will be developing of a methodology which will
help to implement the specific knowledge network.

Extended abstract
This work intends to evaluate the strategies that facilitate an interaction between Primary Health Care
(PHC) and Public Hospitals (PH) in Portugal to maximize health benefits while rationalizing resources,
taking into account that health units aim to achieve service efficiency and user satisfaction while
reducing costs.
The development of Communication and Information Technologies (CIT) for health sector is one of
the fundamental strategies for the articulation of PHC and PH, providing excellent resources to
improve the national health system (NHS)1. They can be decisive in obtaining direct health gains for
the individual, family and community and, indirectly, gains for the economy of a country (economic
and social development). Currently, there is an electronic form ISHU2 in PHC and the IHI3 in PH,
which enables the interaction of administrative information and the ALERT ® (which makes the
clinical referral of users of PHC for PH). CIT in the Portuguese health system could create a Personal
Health Records, with the possibility of going by adding relevant information about their health
(Electronic Health Records), to centralize all clinical information (e.g.: medical history, medications,
test results, allergies) available on a network (important for an adequate diagnosis and treatment),
avoiding the repetition of such tests and unnecessary duplication of information, with guarantied
secure access. Moreover, the data entered by users may be used (while respecting the ethical principles
of confidentiality and total security) for epidemiological research (e.g., knowing the incidence of a
type of pathology(s) in a given region), and also for the management of health institutions (e.g.,
measuring the productivity of a Hospital and to produce quality indicators), integrated in the
Portuguese NHS. Finally, institutions should increasingly work in networks, be more flexible and
adaptable to changes, with the management being responsible for triggering the organizational changes
that can bring this about.
In short, the articulation of PHC and PH could be improved by efficient information networks.
Nevertheless, an efficient health care system also depends on well-structured systems that provide
products and services when and where needed, control costs and performance and identify areas for
improvement. So, further research on this is needed to better evaluate this strategy.

Extended abstract
The use of frameworks for development simulation had been the focus of several projects, some of
them specifically for medical applications. Some advantages of using those frameworks are reuse of
code, fast integration of tasks and unified code for hardware support. In general, they allow
development of medical simulations that are composed by 3D model import, interactive deformation,
stereoscopic visualization, collaborative simulation, etc. However, only a few frameworks provide
support for user assessment, volumetric approaches and visual programming interfaces. The need of
applications for realistic training of medical professionals motivated the development of the framework
CyberMed [1]. Since the year 2006, this framework provides a set of features that allows users to
build, free of charge, interactive virtual environments for realistic medical training. In the year 2008
the first version was launched with support for 3D model reading, collision detection, deformation,
stereoscopic visualization, haptic interaction and user assessment. Since then, the project has been
expanded with new features and nowadays has new components to support network communication,
collaborative tasks and optical and magnetic tracking, besides new assessment methods.
Three modules compose the CyberMed framework: Application Engine, Utils and Core. The
Application Engine module has the components that can integrate a medical simulation. These
components are independent and can be used separately or grouped. The Core module has the model
readers, data structure and managing of interators and tasks. The Utils module has mathematical
operators and functions that are used by the other modules. Since all data related to the models used in
simulation are managed by a data structure (DS) in the Core module, the replacement or expansion of
this DS must be considered to support cut and suture in a realistic way.
Cutting and suturing are very common and important tasks within surgery. They need to be done
accurately, following the path traced out by the user as close as possible, while maintaining the
stability and efficiency of the overall simulation. An important issue in cutting and suturing simulation
is focused on increasing the realism of modeling soft tissues. In general, there are two methods:
surface-based models and volume-based models. Surface models that have been implemented range
from continuous, snake-based models, to discrete mass-spring models based on triangular meshes. The
problem with all surface-based models, when used to simulate tissue with interior structure, is that they
do not explicitly model the interior. Therefore, complex interactions between the tissue surface and the
interior structure cannot be modeled. Volume-based models can simulate interior structure because
25

they encode the entire object, and model the interactions between the interior structure and the exterior
of the object. Therefore they are more powerful, although the computation is more complex and
expensive.
CyberMed 2.0 uses the Opposite Face (OF) data structure [2] in its Core module. The OF structure
is not only limited in regards to mesh type representation (only represents triangular or tetrahedral
meshes), but also in regard to mesh component representation (does not explicitly represent edges nor
faces). These limitations might compromise future extensions of the CyberMed system, for example,
some elastic mesh applications might need additional information related to the edge component of a
mesh. Due to the limitations of OF structure, it was decided to migrate to Mate Face structure [3].
Even though a lot of internal changes to the CyberMed system were needed, these limitations are too
compromising for future expansion.
The Mate Face (MF) DS is a topological structure developed to expand the OF in terms of the
representation type of elements and types of 2D or 3D meshes. Similarly to the OF structure, the
development of this structure was focused on two main features: ease of use and flexibility. The main
difference to the OF structure is that the MF structure not only is able to represent triangular and
tetrahedral meshes, but also quadrilateral and hybrid surface meshes, and hexahedral, prismatic and
pyramidal volumetric meshes. Another major difference between the two structures is that the MF
structure represents the edges and faces explicitly.
The major problem that comes with the DS migration in the CyberMed system is that all classes that
depended on the previous DS needed to be adapted. The general idea for the support of volumetric
meshes in the CyberMed system is that two instances of each volumetric mesh are stored in the
system: the full mesh and the surface of the volumetric mesh. Basically, while the system reads a
volumetric mesh file and stores its data, the system’s shell classes obtain its surface (as a different
mesh instance) and store it. Since the collision and visualization only need the surface of the mesh to
do their operations, this is where the surface instance comes in handy. It should be noted that, while the
cut and suture operations are happening, the surface of the volumetric instance is deformed, the surface
instance being automatically updated to show the resulting deformations.
In order to demonstrate the volumetric support of the mate face data structure, a bunny model was
tested with the CyberMed with the MF integrated. The bunny comes from vtk file, which has 49918
volumetric meshes and 198607 vertices. Now two types of file formats are supported in CyberMed, the
wrl file format for surface model and the vtk file format for volumetric model. Realistic graphical
display, collision detection, and haptic force feedback have also been implemented in CyberMed based
on volumetric model.

This work presents some contributions towards Interactive Digital Television (iDTv), focusing on the
central issue of the interactivity channel on the context of the Brazilian Digital Television System
Terrestrial (SBTVD-T or ISDB-TB), highlighting the necessary infrastructure, applications and
services that can help with the challenges of promoting digital inclusion in Brazil. As a product of this
investigation, a prototype of a Service Guide to support the promotion of citizenship through digital
inclusion is under development.
In the context of SBTVD-T, applications can be built to explore different forms of services, ranging
from the popular EPG (Electronic Program Guides) and voting polls, and reaching the portals of public
services, by example [1]. The life cycle begins with the production and distribution of audio and video
streams that are multiplexed to form structures in Transport Stream (TS), besides objects carousel
(audio, video, images, text, graphics and executable/interpreted applications). These structures are
received and presented at the access terminal of the viewer/user. The last stage is focused on the
interaction of the viewer/user with resident applications without using the back channel; the interaction
is completed using the back channel via any communication infrastructure [2].
The applications of the Service Guide for Citizenship will be embedded in equipment receptors (settop
boxes), reaching the homes of viewers/users. A summary of applications is presented in the
following: a) Understanding Dengue (a typical disease that occurs in Brazil); b) Doctors in Your
Home; c) Health Tests; d) In Case of Emergency; e) Comprehending the Public Administration; f) The
Community Sends News; g) Banking; h) Repository of News; i) The School on TV. New features and
applications can be developed and aggregated into the guide [3]. Tests are being conducted both in the
laboratory and real broadcast environment, created by broadcaster partners. Results of these tests and
developments will be reported in further works.

Abstract. This study defines the nature, scope, pace, and consequences of the development of
globalization waves over the last 500 years. Such waves as led by Pax Portugannica, Pax
Britannica, Pax Americana and Pax Sovietica, Pax Consortia, and Pax Virtualiziana are defined.
They are graphically modeled and compared within four dimensions: guiding, executable,
technological, and societal In conclusion, Portuguese and British Globalizations expanded the
world physically and mentally as the Triumph of Humanity, the subsequent globalizations have
been testing humanity over the last 100 years and continue to test it, since despite strong
technological and economic development, the morality and ethics of humans are in question today.
However, there is some hope that revitalized dialectics between Pax Consortia and Pax
Virtualiziana may lead us to the Triumph of Humanity again.

Abstract. The engineer’s doings in the new millennium have to cope with the ecological quality
objectives, claimed by requirements for sustainable long-term growth; the challenge is
extraordinary and involves socio-cultural aspects, too. Here, an overview of the state of the arts is
flashed, in particular addressing: - the design of ‘product-service’ items, deliberately considering
the early specifications for the lifecycle and the dismissal phases and: - the integration
prerequisites in the supply chain management, explaining the usefulness of networks aids and the
connected commercial modifications. The discussion, although offering sketchy suggestions,
concerns the proper assessing of the life cycle eco-coherence as utter entrepreneurial challenge: the
business design prerequisites incorporate legal issues, so it is not sufficient they are separately
dealt with outside the firm.

Abstract. Our research aims to analyze the digital divide within the European Union 27 (EU-27).
Hence we used a multivariate approach, more specifically Factor Analysis, to study the digital
disparities between European Countries. Two latent dimensions on this subject were found. We
also found statistical evidence that one of the dimensions on digital development is higher in the
original 15 European countries. Therefore, considerable disparities on the Information society
were found.

Abstract. In this paper, the process of constant innovation is analyzed comparing with the various
economic eras that humanity has come through and even with the level of countries’ development.
While technology enables the possible application of knowledge, the level of expertise may be
evaluated by the effective outcomes. In this perspective, analyzing the concept of multimedia
interactive books and its impact on learning, suggests the importance or need for emotional and
knowledge management in a productive way instead of a reproductive type of learning. The aim of
this paper is to present the findings of a Delphi research on the challenges of bringing new
possible business models, economically efficient and socially effective when exploring new media
tools for enhanced learning based on the technology of augmented reality and to adjust new
insights and host new perspectives to the forthcoming human augmented reality.

Abstract. The history of Mankind is a history of evolution, a history of increasing adaptation by
man in relation to his environment. Mankind’s history is also ‘Organization’s history’. As
“Mankind’s instruments” [1], organizations also need to evolve and adapt, finding new solutions
to the emerging challenges and new objectives. Organization‘s first response to its challenges is
strategy. Strategy is a “plan that configures certain company’s aspects, which involves processes,
places, people and time in order to achieve organizational goals” [2]. It is organization’s ‘flight
plan’ to ‘navigate’ towards the future it seeks, its Vision. Under the body of knowledge and
principles of Organizational Engineering – and other theoretical-practical knowledge – this paper
proposes a Strategy Map for the Portuguese Air Force, a tool that clarifies strategy and provides
the organization with a mean of communication capable of generating motivation and creating
focus and alignment, key features to ‘move’ the organization towards its Vision.

Abstract: With the increase of organization’s development that have been happening in the latest
years, the traditional way in which organizations were seen, have been changed. Factors like
markets uncertainty and the offer increase forced the actual companies to react quickly to these
disturbing factors. The development of management theories connected with the development of
Information Technology (IT) has resulted in news methods and tools that assist the decision
making leaders by supplying access to the correct information in the right time. With this purpose,
appears in the Portuguese Air Force the need to initiate a process of transformation. This study
analyzes if that the process of transformation in Portuguese Air Force has brought improvements
to the organization. This transformation process was initiated by two Chief-of-Staff Directives.
Having in mind that the main goal of these changes is to align the Organization Information
Systems with its strategic objectives, it becomes important to realize what involves this full
process by identifying the adjacent actions to it. While monitoring this change, it´s important to
consider aspects involving a successful transformation, for example, we intend to know the way
transformation was approached by the Portuguese Air Force, that is, if the necessary foundations
were created to sustain the desired change; identify the gains that the process brought to the
organization and identify aspects that may have held back the implementation of this change.

Abstract. Today, more than ever, organizations face daily environmental changes. The source of
change may be a new regulatory law, competitor, business model, hype in technology, new service
trend, or the lack of skilled human resources. In order to understand the factors of change and their
impacts on business strategies, organizations need to have in place a set of tools, methods and
procedures to allow an instantaneous reaction, and foresee proactively the highest number of
variables that will have impact in the organization’s competitive advantages. One of the central
tools that managers have at their disposal to face these challenges come from the use of
Information and Communication Technology (ICT), which are entering into a new stage. The
maturity of some Internet technologies, business intelligence systems and outsourcing business
models allows the availability of new services, based on cloud computing. The rise of new service
trends are taking place, and if an organization is able of combining the advantages of those trends,
it might gain competitive advantage, throughout Business Intelligence as a Service (BIaaS), and
what began as a way to achieve operating savings, will eminently reveal its true disruptive
potential throughout the Internet.

Abstract. Semiconductor manufacturing industry (SMI) has shifted from an IDM (integrated
device manufacturer) to a fabless structure where technology is developed in an alliance to share
high R&D costs and address time to market and time to volume challenges. In this fabless
structure, EDA (electronic design automation) has emerged as a key stake holder to model
increasing design and manufacturing interface complexities and its integration within design flow,
but collaboration within alliances have resulted information sharing and technology transfer as the
key challenges. We argue that IDM model is superior to a fabless structure due to its inherent
ability for faster/superior knowledge capitalization. We benchmarked and analyzed a world
reputed IDM with use-case and SWOT (strength, weakness, opportunity, threat) analyses to
identify the limiting factors that led this transformation and found data and statistics as the core
issues. We have proposed an extended IDM business model where engineering information
systems (EIS) are tuned for design for manufacturability (DFM) compliance to achieve time to
quality (time to volume, time to market) and yield ramp up rate at low cost but effective R&D
efforts.

Abstract. The results-oriented management, performance evaluation systems and operations
alignment entails the creation of a new organizational environment with novel management
practices. This paper addresses organizational strategic alignment issues and offers a modeling
technique as a possible solution. A case study of Information Technology alignment in a public
organization was developed to test and validate the technique. The study uses a methodology to
link the information systems with organizational objectives. The modeling technique proposed by
this methodology can be used by managers to formulate, communicate and align the strategy with
operations execution. Thus, the methodology applied in this case study can assume a central role
in the transformation process of public organizations trying to achieve efficiency and providing
quality services to the citizens and society. Finally, this paper presents a new alignment
management practice based on organizational engineering.

Failures of a Business Process in Enterprise Systems

Abstract. A business process model typically describes a desired flow of events in an ideal
environment. However, the reality tends to be more complicated than what is designed in the
model. During the execution of business process instances, a lot of exceptions may occur. These
exceptions are deviations from the correct, specified sequence of events. Thus it is important to
know the behaviours of process instances in the presence of exceptions. The classical approach of
incorporating exception analysis in process models has been trying to anticipate beforehand all
possible exceptional conditions that might arise and argue the process model with those additional
conditions in order to determine the exception handling actions. This approach, however, might be
problematic because the identification of all possible exceptions relies on the experience and
intuition of the participants. To have a clear understand of the failure behaviour of a business
process is equal important, but first of all, it has to be studied what characteristics of failure often
have. In this paper, we present the initial findings of our project that targets to the enterprise issues
of healthcare systems.

{ma.caict, nba}@cbs.dk
Abstract. The paper looks at the history of two ERP vendors (Maconomy and Navision) in
Denmark pursuing two different business models. On one hand, Maconomy decided to develop,
sell and implement ERP packages directly to customer. They believed they would be best at it, and
they would obtain valuable information about customer requirements in the process. On the other
hand, Navision adopted a business model which relied on an ecosystem of partners consisting of
value added resellers (VAR) and independent software vendors (ISV) to sell, implement and
further develop add-ons for their software. The paper presents a Resource Based View (RBV)
analysis comparing and contrasting the resources of the two companies, in order to explain why
Navision was sold for 16 times as much as Maconomy. We posit that the main reason for this huge
difference is the value of Navision’s ecosystem enabling them to achieve economies of scale.

Abstract. The main purpose of introducing business intelligence systems in a firm is to increase
the quality of information available to knowledge workers at various organizational levels.
However, quality information is of little value to firms if it has not been used in firm’s business
processes. Literature suggests the use of information mainly helps organizations in two ways,
namely in managing their business processes and in making decisions. The quantitative analysis
carried out on data from Slovenian medium and large organizations further shows that information
quality differently impacts the two uses of information with impact on business process
management being stronger.

Abstract. A lot of research has been undertaken focusing on ERP systems lifecycles, but very
little paid attention to retirement. ERP retirement means the replacement of an ERP with another.
The aim of this research paper is to investigate why and when should organizations retire their ERP
systems. A convenience case study of an SME has been selected from Egypt. The case study under
investigation has retired their local ERP system and replaced it with SAP ERP. Results of our
analysis indicated that reasons of retirement were: wrong selection, users were not involved in the
selection process, and lack of an official implementation methodology. This is considered a new
finding since main stream literature was mainly focused on retirement after maturity.

Abstract. The research in this paper has looked to find the barriers that small enterprises in
Sweden have faced in the implementation of the e-commerce during pre and post adoption phases.
Taking four small enterprises as case studies the paper is presenting the post adoption barriers
faced by these enterprises that are currently using e-commerce. The outcome is that ‘security
issues associated with e-commerce’ identified in previous studies appeared as an obstacle in both
pre and post adoption phase. Moreover lack of time to improve e-commerce activities,
synchronization of demand and supply, price war among competitors, need for extensive
marketing effort, payment related hazards are explored and identified as post-adoption barriers.
Finally, a model has been proposed through which we wish to consolidate both pre and post
adoption barriers and have a complete picture of the barriers faced by small enterprises in
implementing e-commerce in Sweden.

Abstract. Enterprise Resource Planning (ERP) systems have been heavily adopted in developed
countries in the past decade and most studies on ERP adoption and selection focuses on these
countries. With the emerging trend of ERP adoption in developing countries, the crucial question
is: How to select an adequate ERP system. Of course this is not a new issue and already discussed
in the developed countries, but many of the available studies are highly focused on this setting.
Developing countries can actually adopt the available selection models but the suitability of the
models has to be approved in the context of these countries. This proposal, therefore, intends to
indicate the methodology to be followed in analyzing the suitability of the existing selection
models in order to come up with a prototype of a suitable ERP system selection model for
Ethiopia’s context.

Abstract. The paper discusses both the complementary factors and contradictions of adoption
ERP based systems with enterprise 2.0. ERP is well known as its’ efficient business process
management. Also the high failure rate the system implementation is famous as well. According to
[1], ERP systems could achieve efficient business performance by enabling a standardized
business process design, but at a cost of flexibility in operations. However, enterprise 2.0 supports
flexible business process management, informal and less structured interactions [3],[4],[21].
Traditional researcher claimed efficiency and flexibility may seem incompatible in that they are
different business objectives and may exist in different organizational environments. However, the
paper will break traditional norms that combine ERP and enterprise 2.0 in a single enterprise to
improve both efficient and flexible operations simultaneously. Based on the multiple cases studies,
four cases presented different attitudes on usage ERP systems and enterprise social systems. Based
on socio-technical theory, the paper presents in-depth analysis benefits of combination ERP with
enterprise 2.0 for these firms.

Abstract. Current generic Research, Development and Innovation (R&D&i) management systems
implemented in businesses lack of project requirements specification and they hardly integrate IT
control issues. This paper focuses on the definition of a model for managing R&D&i projects in
companies. This model, based on ISO/UNE 166002:2006 [1] standard, addresses the shortcomings
that the generic models have by means of integrating good practices in IT management from
framework COBIT [2]. Moreover, our proposed model includes requirements for research and
development projects as specified in ISO/UNE 166001:2006 [3] standard. Once this reference
model is set, we introduce the GIDIX software for giving support while developing such projects.
This software can be used as the main tool for managing R&D&i projects in a company making
use of our R&D&i management system model and it incorporates the features needed to fulfill the
requirements specified by our model.

Abstract. Many companies act in fast developing markets, characterized by a strong global
competition and rapidly changing production structures. Continuous development of advanced
technologies leads to frequent product changes and to short production runs. Collaboration across
the supply chain is one possibility to face these challenges and to stay competitive. Effective
collaboration requires an intensive information exchange between supply chain partners.
Currently, there are several concepts and tools, automating information exchanges on the
operational level. However, collaboration and thus the corresponding information exchange
support on the tactical and strategic levels have been neglected so far. The CONVERGE project
aims to fill this gap. It develops a framework and tools for exchanging tactical and strategic
information between equally powered supply chain partners. This contribution describes the
results of a problem analysis, conducted to determine requirements on a suitable business
information tool. Several requirements, towards the information exchange itself were identified.
Furthermore, the article describes characteristics and deduced profiles, which aim to support the
identification of a collaboration’s particular requirements. These characteristics cover a company’s
need for information exchange, security and confidentiality as well as its supply chain stability.

Abstract: This article is a work about the development of a model for the engineering requirement
based on ontology. The development patterns are not used efficiently, especially for nonobservance
of the principles of requirements engineering. The overall objective of the article is to
propose the use of a ontology based on the artifacts of software requirements engineering and can
be used on any project developed in any organization. The method uses experimental procedures,
which will be held in experiments with real situations in a project in progress at a reputable
company in the development of hardware, but that currently covers its business in the software
services industry. As a result, there was an improved understanding of software requirements, as
well as its trace within the scope of the project, that is, one can easily traverse the model and
identify all the artifacts impacted by the change.

Abstract. According to state of the art literature, software product lines are an effective way to
achieve economies of scale through reusability while coping with the problem of variability in
related software systems. Fundamentals of variability management and product lines have been
available in the software engineering research field for several decades. Nevertheless, projects to
cope with variability in practice tend to fall short of target. The reason for this gap between sound
theories and poor practice, common in multiple software engineering subfields, remains unclear.
Therefore, an empirical study was conducted in a large-scale software dependent multinational.
The results of this case study show a number of factors that impact successful variability practice.
These factors can be abstracted into general hypotheses useful for bridging the gap between theory
and practice. Based on the sources of discrepancy, this research suggests a practical way to
overcome the obstacles on the road towards successful variability management.

Abstract. Software product lines (SPL) are a development paradigm focused on reducing costs
through improved organization productivity and enhanced process quality. After careful analysis
of existing SPL development methods, we noted that most of them do not provide a sound answer
to some typical concerns – e.g. accurate business/domain analysis or efficient change management
– of developing business information systems. Therefore, we decided to go forward to an SPL
methodology definition that encompasses methods, activities and applicable technologies. The
goal of this paper is to present our research approach and the main outcome of our work, an SPL
oriented methodology (SPLUP) especially suited for business information systems development.

Abstract. The Internet of Things (IoT) aims at bridging the gap between real-world business
processes and information systems. When attached to physical items, the IoT technologies such as
sensor networks transform objects of the supply chain into smart items. These items have the
ability to capture context data and provide business process management systems (BPMSs) with a
representation of things. To adequately describe a business process, process engineers commonly
use Business Process Modelling Languages (BPMLs). However, in a larger scope, BPMLs differ
according to the application area they are used in, and there is no current language solution to
represent IoT context data within a process model. In this paper we introduce the goals for a
BPML to represent these data. The language will enable process engineers to model business
process behaviour taking into account IoT context data.

Abstract. The present article describes a systemic approach to better support the decision making
process by creating a tool based on an ontology for integrative analysis of health and safety risks
that can occur in a workplace activity development. The designed ontology creates the possibility
to show and characterize the potential work accidents and/or diseases and decide better for an
appropriate preventive or corrective measure. The ontology is a structure in four chapters/subontologies
(human being subsystem, work duty subsystem, machine subsystem and work
environment subsystem) and its content allows the classification of all the concepts used in the
health and safety risk evaluation process (risk characterization, impact, health problems, measures
etc.), including important relationships between the concepts. In addition, each class will be
enriched with different properties that will be used for defining the decision-making tool, to better
identify the significant health and safety aspects in a risk evaluation process and to appreciate their
impact in order to provide efficient/effectiveness corrective measures (for eliminating or
minimizing risk impact). The research results will increase companies’ competitiveness by
optimizing the resources dedicated to different management systems.

Abstract. Following a generic process model, recommendations are given for the implementation
of ERP systems in medium size companies. We focus on those companies because they are
confronted with the same tasks as large companies, but medium-size companies command fewer
resources and therefore have to act more efficiently to succeed in the implementation of an ERP
system. The content of the paper stretches from project management, business process
reengineering, application development, reporting and customizing to choosing hardware and keyusers,
data migration, and users’ training. While other publications give rather general advice,
recommendations in this paper are use-oriented and easy to apply. Furthermore, the
recommendations do not depend on any particular ERP system.

Abstract. This paper focuses on ERP post-implementation issues in Small-and-Medium-Sized
Enterprises (SMEs).We conducted a case study in a small Norwegian retail company. We studied
the enterprise in the period after going live with their new ERP system. Certain challenges were
observed such as security risks because of inaccurate configuration of the system, difficulties with
operational issues such as sending invoices and getting sales reports, inaccurate inventory,
insufficient training arrangement, workarounds, conflicting incentives among customer, reseller
and consultant. There were human consequences for end users since the implementation of the
system caused stress among some of the employees. This study has implications for other SMEs
planning to implement ERP systems.

Abstract. The use of best practice manufacturing processes by Greek SMEs is examined, along
with the corresponding process implementations with packaged enterprise systems (ES). The study
analyzes individual processes from an implementer’s perspective, focuses on deficient process use
cases, and explores the causes of such deficiencies. Production master data, and planning,
scheduling, execution, costing, and Business Intelligence processes are analyzed on a sample of 15
Greek SMEs which have successful implementations of a single ERP system. Deficiencies are
observed in production planning, scheduling and standard costing. They can be attributed to the
lack of knowledge and experience, and to the business culture of the companies. A broad business
process reengineering is also required before these processes can be implemented. The results
suggest that, under low process and ES use maturity conditions, an analysis of individual processes
is necessary before the evaluation of higher-level business process orientation and business
process maturity indicators.

A Decision Support System for ERP systems implementation in
Small Medium Enterprises (SMEs)
Mahmood Ali, Ying Xie
Business School, Old Royal Naval College, University of Greenwich, London, UK
Abstract. Small medium enterprises (SMEs) face considerable challenges in implementing
enterprise resource planning (ERP) systems, however due to their benefits ERP systems are
becoming an essential and integral part of SMEs business strategy. This study investigates the
implementation of (ERP) systems in SMEs and the role played by certain critical success factors
(CSFs) in its successful implementation. Based on primary data collected, the relationship between
the variables of time, coast and performance realised is established. A simulation model based
decision support system (DSS) has been proposed and developed. The DSS model developed
assist in decision making process during implementation by running different implementation
scenarios and opting for most optimised solution which give higher performance at a reasonable
cost at optimum time. By drawing upon this model, we can relate to how SME can better utilise
and prioritise different CSFs and resources by choosing the best implementation strategy before
real life implementation thus saving time and money.

Abstract. Based on a literature review, it can be stated that there had been very little research
published focused on enterprise resource planning (ERP) systems post-implementation period.
This paper tries to contribute to filling in this gap in theory. The aim of this paper is to analyze
whether a significant difference in the impact of ERP systems implementation on overall IS/IT
costs can be found, as well as on the proportion of the IT/IS costs attributed to IT and other
departments, on efficiency as profitability, on effectiveness as productivity, and on the availability
of IS/IT services. The research is based on data from large Slovak and Slovenian companies. The
models control for the extent and successfulness of the ERP system implementation and for the IT
focus of the company.

sonia.ayachi@isgs.rnu.tn, belaazi_maherzia@yahoo.fr
Abstract: A meta-model is proposed in this paper dealing with different concepts involved in
reengineering operations. This meta-model, in which both business process reengineering and
software reengineering are considered, is accompanied by an approach to analyze and diagnose
processes and software components. A prototype has been developed supporting this approach and
has been designed on the basis of the proposed reengineering meta-model. These ideas are
validated by a case study which is presented in this paper, related to a process in the high
education field. The context of this case study is described, then the corresponding instances of the
meta-model are presented and some improvement results are exposed.

Abstract. Gaps between enterprise systems and organizations have long been of primary concern
to both researchers and practitioners. While much attention has been paid to the fit of business
processes, enterprise systems vendors have recently begun to focus on representing organizational
roles in their systems as a mean of closing the gaps between system and organization. This paper
presents findings from a case study of how a large enterprise systems vendor represented rolerelated
concepts in its enterprise model and system with emphasis on role content and role
relationships. A key finding from the study was that while the majority of role-related concepts
were represented in the vendor’s enterprise model, the implementation of roles in both the model
and the actual system lacked support for remodelling and reassignment of the tasks contained in
the roles.

Abstract. Public transport contributes to the welfare of the citizens and improves the social
development of the countries. The contribution of Public Transport to the GNP is estimated to be
around 1% in Europe. Worldwide, local authorities dedicate between 15 to a 20 per cent of their
yearly budget to urban transport. Intelligent Transport Aid Systems (ITA Systems) are integral real
time control systems for monitoring transportations networks. The main objective of this research
consists of examining the relationship between the investments in Integrated Intelligent Transport
Aid Systems (ITA Systems) and Value Creation in Urban Bus Companies. Results show that the
investment in Intelligent Transport Aid Systems created value and generates a better performance
in firms operating urban transport along time.

Abstract. Presently living in a period of fast economic changes, governments have found the need
to adopt measures that promote the rationalisation and profitability of the available resources. As a
member of the European Union and simultaneously of the European Economic Community,
Portugal is obliged to meet the convergence criteria set out in the Pact of Stability and growth, and
therefore forced to introduce reforms. This study includes some the recent reforms introduced in
Portugal in the scope of the new public management, and the revision of the literature available on
the subject.

Abstract. A crowdsourcing innovation intermediary performs mediation activities between
companies that have a problem to solve or that seek a business opportunity, and a group of people
motivated to present ideas based on their knowledge, experience and wisdom, taking advantage of
technology sharing and collaboration emerging from Web2.0. As far as we know, most of the
present intermediaries don´t have, yet, an integrated vision that combines the creation of value
through community development, brokering and technology transfer. In this paper we present a
proposal of a knowledge repository framework for crowdsourcing innovation that enables effective
support and integration of the activities developed in the process of value creation (community
building, brokering and technology transfer), modeled using ontology engineering methods.

Abstract. Information flows across the organization are complex and procedures employed to
understand, share and control organizational knowledge and experiences should be properly
supported by collaborative environments. Nevertheless, few collaborative methodologies had been
proposed to describe and evolve business processes. In the future, business processes models
should be the result of cross-team and cross-departmental collaboration, with involved business
people sharing their personal knowledge and formalizing it. This paper focuses on a methodology
for business process discovery and the importance to integrate local information into coherent and
sound process definitions. Business Alignment Methodology (BAM) is a methodology that
provides guidance about how organizational practices and knowledge are gathered to contribute
for business process improvement against current BPM approaches.

A Model to Evaluate the Relational Capital of Organizations
(SNARE RCO)

IST – Instituto Superior Técnico/INESC ID
barao.alexandre@gmail.com, alberto.silva@acm.org
Abstract. We consider social networks as artifacts that are part of organizations. The relational
capital value of a social network represents a contribution that should satisfy demands which are
conducted by social entities. It is not always possible to capture this value in accounting systems
of organizations because it is almost invisible in conventional forms of information systems. There
are several evaluation models, but there is a lack of models for evaluation of relational capital that
combine techniques derived from social network analysis of organizations. The SNARE, short for
“Social Network Analysis and Reengineering Environment”, is a project that has been developed
in recent years with engineering artifacts to represent social networks, and allows researchers to
design and build real scenarios for social networks relational knowledge discovery. We propose
SNARE RCO as a model to evaluate the relational capital of organizations.

Abstract. This paper presents some research results based on the concept of collaborative
infrastructure (as virtual enterprise business network), in order to unify existing standards for
supply chain management and to provide support in various decision making manufacturing
supply networks processes. It intends to facilitate and enhance the required knowledge
management processes linked with the business process management. The virtual enterprise
business network expected to improve small and medium-sized enterprises (SMEs) involvement in
new product manufacturing networking efforts, enables better and faster decision processes and
promotes the development of the business services. As the new product development paradigm
requires evaluated software tools, a knowledge base method built and used for the human
resources (HR) selection as part of the business management process is proposed.

Abstract. An organization cannot function without knowing how much it produces and how much
each product costs. The Portuguese Air Force is no exception, and so, determining the Cost per
Flying Hour is essential for decision-making.
Information concerning the Cost Factors included in the Cost per Flying Hour used to be stored in
various Information Systems, but with the implementation of the Defense Integrated Management
System in Portuguese Air Force, these Information Systems became obsolete, as the Integrated
Management System now concentrates all the information about the Cost Factors. However it did
not have the ability to calculate the Cost per Flying Hour because some of its modules were not yet
implemented. Thus the Cost per Flying Hour began to be calculated using inflation. In 2010 a
Model in which the Cost Factors were obtained directly from sources was proposed.
In this investigation work, it is recommended that the new Model start to use the Integrated
Management System data, being the main source of information. Thus, it is defined and proposed
a Calculation’s Model of Cost per Flying Hour, presenting its formula and the method of obtaining
the information for it.

Abstract. With Virtual Reality (VR) systems it is possible to visualize three-dimensional
environments with a high level of detail and visual fidelity. The users can manipulate and interact
with those virtual environments in an intuitive way, close to reality. The VR systems enable the
access to digital services that can promote, amongst others, collaborative work, data sharing or e-
commerce. In this paper, we present a multidisciplinary solution that can offer added value to users
through a collaborative environment with an intuitive interface. This environment will use georeferenced
databases to replicate urban environments and represent real world problems in a
virtual way, making possible a better and more flexible approach in order to solve them. It is also
proposed an architecture and some digital services are illustrated to show its potential.

Abstract. Information contained within documents is an essential ingredient of any office
operation. A content management application (CMA) is an organization plan for the conception,
use, retention, disposal and selective preservation of its data. Using an appropriate CMA
framework can greatly help Macao Government agencies, for instance, that are increasingly using
electronic means to create, exchange and store a major variety of records daily. By definition, a
record is information, in whatever form, for government functions, activities, decisions and other
important transactions. As expected, as the volume of electronic information increases, so does the
complexity of managing electronic records. This project goal was to evaluate the software
capabilities of the Alfresco © Enterprise Content Management (ECM) against a set of functional
requirements, aimed by the Macao Government agency. Drawing on the results of this evaluation,
the present analysis concludes that Alfresco © ECM is capable of supporting an entire agency needs
related to the management of its records content.

Abstract. The construction of a building has been traditionally supported on the timeline
schedules of the construction activities established in each case, and on technical drawings of the
project. A prototype based on Virtual Reality (VR) technology with application to construction
planning, was implemented. This interactive virtual model intends to present the project in a threedimensional
(3D) way, connected to construction planning schedule, resulting in a valuable asset
in monitoring the development of the construction activity, based on the construction planning
designed. The 4D application considers the time factor showing the 3D geometry of the distinct
steps of the construction activity, according to the plan establish to the construction. The 4D model
offers a detailed analysis of the construction project. Additionally, VR technology is used and
presented as an innovative visual tool. It allows the visualization of different stages of the
construction and the interaction with the construction activity. This application clearly shows the
constructive process, avoiding inaccuracies and building errors, and so improving the
communication between partners in the construction process. This tool is an important support in
project conception and application.

Abstract. For modern airports that daily receive up to a hundred thousand or more passengers,
visitors and workers, easy accessibility is key in order to become the preferred multi-modal hub.
To achieve high-quality accessibility by means of all kinds of transport modalities, an Enterprise
Information Subsystem (EIS) that measures the quality of the provided airport accessibility is a
conditio sine qua non. This paper takes up the challenge for designing such an information system
while taking the landside perspective. The main contribution concerns a performance
measurement framework in which clients’ demands can be related to the transport services offered
by means of a measurable set of accessibility indicators. Based on this, an overall picture on the
airport accessibility quality can be created. To illustrate the feasibility of the framework, the
results of three (partial) implementation steps towards an EIS are shown. The first one relates to
client profiling; the other two to performance measuring dashboards. We finalize by reflecting on
the use of the performance measurement system for improved decision-making and by drawing
conclusions.

programmed event item. In this paper we present AEMS – an advanced event management system
with project management like features. We present the requirements for such features, based on a
case study carried out with a real-world customer. Then, we describe the development of AEMS
and discuss its data model, architecture and the developed prototype. With AEMS, our customer
will be able to manage all activities, resources and costs associated with an event. The results from
applying our development to our real-world customer will allow us to derive AEMS to a generic
software product.

Abstract. In these recent years, with the gain in popularity of online games, we are witnessing a
progressive increment in the number of massive multiplayer online games available over the
Internet. Given the scalability requirements imposed by a huge population of users over an
extended length of time, game providers face the major challenge of long-term IT infrastructures
dimensioning. In particular, the risks are over-allocation (wasting resource and money) or nontimely
upgrades (loosing subscribers and revenues.) In this paper we advocate Cloud Computing
as a viable solution to dynamically allocate resource for a massive game service infrastructure in
order to satisfy users' needs while minimizing maintenance costs. To this extent we envision a
mid-term future where game provisioning will be performed by means of a three-tier architecture:
the users, the game provider, and the cloud provider. We believe that many medium/small game
providers may benefit from the on-demand resources allocation infrastructure offered by the cloud,
due to shorter deployment time and reduced total cost of ownership.

Abstract. In the last few years there has been a dramatic development in voice communications
technology with a significant move towards Voice over the Internet Protocol (VoIP). Since the
Internet was primarily designed as a best-effort technology, good quality conversation and
intelligibility are not guaranteed. In this paper we address quality evaluation of voice
communications in the context of modern enterprises using VoIP as an emerging technology with
impact in their activity. Relevant factors for service providers and enterprises using VoIP
technology are described, such as those related to measurement of intelligibility and evaluation of
overall voice communications quality. Also, the most relevant voice quality evaluation methods
recommended by the ITU-T are described along with the main features that can be used to
improve voice communications. Fundamental concepts are presented, such as intrusive, non
intrusive, objective, subjective and parametric methods. Mastering the concepts of such emerging
technology, has recently lead to research and development of a model-based voice quality monitor
for VoIP services. After its successful implementation, it is now fully operational in a Portuguese
telecom operator.

Abstract. In this paper anti-spam filtering is presented as a cumbersome service, as opposing to a
software product perspective. The human effort for setting up, adaptation, maintenance and tuning
of filters for spam detection is stressed. Because choosing the proper scores (relevance) for the
spam filters is essential to the accuracy of the anti-spam system and one of the biggest challenges
for the Apache SpamAssassin project (the most widely adopted anti-spam open-source software),
we present a survey on single and multi-objective optimization studies for this purpose. Our
survey constitutes a contribution and a stimulus for further research on this open research topic,
with particular emphasis on evolutionary multi-objective approaches.

Abstract. The proliferation of social networking and sharing of all kinds of information, including
location information, triggered the emergence of new services, including location-based services.
In this paper we enhance location-based services by adding a temporal component, allowing
information about past and future locations to be considered. Such services may be important for
those who want other know their locations, for personal or professional reasons, for example
allowing others to have knowledge of ones agenda, including locations and times, without need to
establish personal contact. We defined an architecture that provides location-based services to
users of social networks, including information about time and space, which can be accessed
through the social network or a mobile application. To assert the validity of the proposed
framework, we defined case studies to evaluate the system, where real situations were considered.

Abstract. Urban problems, such as holes in the pavement, poor accesses to wheelchairs or lack of
public lighting, are becoming pervasive. Despite the fact that most of these problems directly
affect life quality and sometimes even safety, not everyone has the readiness or initiative to report
them to the proper authorities. This fact makes these “black spots” difficult to identify and the
repairing process slow. Citizens@City is an Android mobile application that allows the general
population to play a more active role in the identification of these problems by reporting them to
the proper authorities in a simple and fast way. Moreover, citizens will have the possibility to
follow the identification and repairing processes, and know at a given moment its status (e.g.
identified, repairing scheduled, solved). Additionally, it will also allow the proper authorities to
identify and manage the reported problems, from their identification until they are solved.

Abstract. The increasing search for applications that enable the sharing of experiences and the
absence of applications that motivate the sharing of local knowledge prompted the development of
Visit-M. It is a mobile application that allows residents and visitors of a city to share their
experiences and knowledge as a community. Visit-M stimulates a strong social participation,
enabling contributions of users alongside with contributions of local authorities. This paper
presents a mobile and collaborative digital agenda for local events, places and routes capable of
triggering a “social network” effect, generating continuous interest to create a dynamic
community. To assess the integration of the developed application into the local community, local
authorities were involved and potential users were invited to test the application with encouraging
preliminary results.

Abstract. Mobile devices are growing on a pace without precedents. It is estimated that by 2013
there will be about 1.1 Billion Smartphones on use. This quick growth on Smartphone numbers
and the appearance of marketplaces where mobile applications can easily be bought or
downloaded is turning mobile development into a big market. As the number of users grows in a
fast pace, so does the demand for new applications, leading to faster development cycles in order
to produce faster results. In many cases, mobile applications are connected to pre-existing systems
and it is necessary to find a quick, but stable, secure and light way to establish a communication
between the mobile application and the pre-existing background system. This article aims to show
how restful Webservices, combined with JSON, may help developers to fill this gap while keeping
security, stability and speed.

Abstract. Enterprise Application Integration (EAI) is a field of Software Engineering. Its focus is
on helping software engineers integrate existing applications at a sensible costs, so that they can
easily implement and evolve business processes. EAI solutions are distributed in nature, which
makes them inherently prone to failures. In this paper, we report on a proposal to address error
detection in EAI solutions. The main contribution is that it can deal with both choreographies and
orchestrations and that it is independent from the execution model used.

Abstract. Small and medium size enterprises (SMEs) are greatly affected by cost escalations and
overruns Reliable cost factors estimation and management is a key for the success of Enterprise
Resource Planning (ERP) systems adoptions in enterprises generally and SMEs specifically. This
research area is still immature and needs a considerable amount of research to seek solid and
realistic cost factors estimation. Majority of research in this area targets the enhancement of
estimates calculated by COCOMO family models. This research is the beginning of a series of
models that would try to replace COCOMO with other models that could be more adequate and
focused on ERP adoptions. This paper introduces a feed-forward back propagation artificial neural
network model for cost factors estimation. We comment on results, merits and limitations of the
model proposed. Although the model addresses SMEs, however, it could be extended and applied
in various environments and contexts.

Abstract. To transmit fidelity the information, at long distances, was from the beginning, a great
human dream. The information signal, when transmitted from the emitter to the receiver, suffers
attenuation and distortion. Then, it is necessary to use frequently a regenerator to restore the
original amplitude and also to retime the bit original period. The amplitude can be restored with an
amplifier with AGC (Automatic Gain Control) and the bit duration can be retimed with a
synchronizer with AFC (Automatic Frequency Control).

Abstract. This paper focuses on decision points, which are a feature of knowledge-intensive
processes; in particular, task selection and data selection are addressed. Task selection occurs
when the same business entities can be handled with different tasks, and a choice has to be made;
data selection takes place when the entities to be acted on have to be selected from among those
available. A notation called Task-Oriented Modeling of business Processes (TOMP) is presented
with the help of an example showing a number of decision points. This paper also discusses the
impact of decision points on to-do lists.

Abstract. The scope of this work covers the study of models developed for assessing critical
aspects of consumer use and acceptance of technology-based products and services. We used the
Technology Acceptance Model (TAM), and the Index of Readiness for the use of Technology
(TRI) as theoretical references. We carried out field research on Internet banking users in order to:
(1) evaluate the differences between the groups in terms of predisposition towards technology
using the TRI model; and (2) test whether the influencing factors of this model could be
antecedents to the main construct of the technology acceptance model (TAM). The analyses
showed that for proposal (1), three of the four dimensions, - optimism, insecurity and discomfort, -
presented significant differences between the groups; and for proposal (2), the factor ´optimism`, a
positive view of technology, was observed to be a significant antecedent of the intention to use online
services.

Abstract. Motivation is a key factor that influences individual effort, which, in turn, affects
individual and organizational performance. Nevertheless, motivation at work depends on the
organizational rewards and incentives, according to individual goals. This paper reports on the
development of an instrument designed to measure the motivation of Information Technology
people at their workplace. Psychology theories and work addressing intrinsic and extrinsic
motivation have been studied. Some motivation instruments were reviewed and analyzed.
Specificities and special characteristics regarding IT workers were evidenced and combined with
other more general motivation factors. The instrument has been developed according to the five
dimensions of the Worldatwork framework, resulting in a set of 30 scale items addressing 23
variables. Besides measuring the IT motivation levels, the tool may also help any organization to
understand the weaknesses and strengths regarding incentive policies, and therefore, assist on the
definition of new ones.

Abstract. We do believe that it is possible to describe the people work in an organization and its
relationship with Information Technology. For this purpose we build an analysis of the people
work, using some principles derived from the Activity Theory and the Structuration Model of
Technology. We propose an analytic framework and a method that allows us to watch work made
by people and understands how Technologies is used in organization and how the organization can
influence the use of technologies. The analytical framework and the method cover the different
functions people play in the work, how changes in the work occur over time, and the role played
by information technologies after each change. It is our faith that this method can increase the
alignment between people, their work and the information technologies in an organization. To test
the operational effectiveness of the method and analytical framework, these were applied to a case
study. The example chosen is the work within a recruitment organization specialized in finding
experts to technological areas. The description was obtained through interviews and on the
observation on the work performed by people.

Abstract. Organizational theory is in a poor state today. Supporting this claim, an article in Nature
in 2011 listed the top challenges, including at fifth, the inability by social scientists to aggregate
individual data to group, organizational and system levels. We have proposed that this failure
derives from treating interdependence as a hindrance to experimental replications rather than the
primary characteristic of social behavior. Recent studies have shown that bistability can be used
theoretically to explain states of interdependence common to group debates preceding a decision
(e.g., interdependently speaking and listening, and reacting). The goal of this study is to
investigate interdependence in groups in the laboratory when specific parameters are placed on
debate outcomes. Participants are instructed to engage in debate with one another over various
topics (i.e., business, abortion, and race) and placed under one of two decision rules as instructed:
consensus or majority rule. The degree to which participants remain “engaged” in the debate is of
particular interest in this study. Prior to the test trial each participant completes a pre-discussion
questionnaire designed to ascertain personal beliefs regarding each of the topics discussed.
Participants complete a similar questionnaire immediately following the test trials. In addition,
galvanic skin responses (GSR) and utterance counts over time are being obtained from randomly
selected participants as a measure of autonomic arousal. We plan to analyze with time series. We
expect that time-series data from groups, teams and organizations can augment self-reported data
collected from individuals. Preliminary findings will be reviewed.

Abstract. The confluence of education with the evolution of technology boosted the paradigm
shift of the face-to-face learning to distance learning. In this scenario e-Learning plays an essential
role as a facilitator of the teaching/learning process. However new demands associated with the
new Web paradigm require that existent e-Learning environments characterized mostly by
monolithic systems begin interacting with new specialized services. In this decentralized scenario
the definition of a strategy of interoperability is the cornerstone to ensure the standardization
communication among systems. This paper presents a definition of an interoperability strategy for
an e-Learning environment at our School (ESEIG) called PEACE – Project for ESEIG Academic
Content Environment. This new interoperability model relies on the application of several
coordination and integration standards on several services, controlled by teachers and students, and
included in the PEACE environment such as social networks, repositories, libraries, e-portfolios,
intelligent tutors, recommendation systems and virtual classrooms.

Abstract. Technology is changing society, organizations, and interactions between service
organizations and customers at a fast pace. Moreover, technology is transforming the nature of
services and, in academia, multidisciplinary research is trying to make sense of these changes and
leverage the opportunity of service innovation in different fields. After a brief review of the
literature focused on services, we found that the term “service” is often used to mean many
different things. This paper explores the meaning and scope of services in technological and
managerial domains. As a final result, we summarize the concepts of services in the broad areas of
management and technology that we found in the literature. Management refers to the concepts
that are often used in the fields of marketing and operations management, whereas technology
includes the service-like concepts from the fields of software engineering and information systems.

Abstract. The practice of Records Management in organizations is becoming a subject of research
as organizations increasingly face the dematerialization of their processes. Standards and
requirements have emerged in order to assist organizations to manage digital records with the
purpose of streamlining their processes and ensuring accountability and evidence of their actions.
However, there is still no guidance on how to embody these requirements into the organization’s
Enterprise Architecture. As a result, this paper explores and analyzes a requirements specification
for records management (MoReq) from the perspective of an enterprise architecture framework
(TOGAF). It intends to give the basic insights about how to incorporate such requirements into the
development process of building an Enterprise Architecture by matching them with the
corresponding architecture specification element or domain.

Abstract. Nowadays, the strategic alignment of information systems has become a priority in most
large organizations. It is a question of aligning the information system on the business strategies of
the organization. This step is aimed at increasing the practical value of the information system and
makes it a strategic asset for the organization. In the literature several approaches have been
developed to solve the problem of alignment. For example the approach of alignment between
architecture and the business context, the approach needs oriented, approach alignment between
process and information system...etc. In this paper we propose a detailed study of each approach
(benefits and limitation) and we propose a comparison between these different approaches.

analysis and the evaluation of business IT alignment, but few proposed solutions applicable to the
strategic and functional level. This paper aims has to fill this gap by proposing a simple approach
for modeling enterprise strategy in the context of strategic alignment. This approach is illustrated

Abstract. There is much evidence that top management support is the single most important
determinant of IS project success. This is especially the case in complex and large-scale IS
projects. Surprisingly however, despite its crucial importance there is only limited knowledge of
the types of behaviour associated with top management support and the reasons for low support
levels. This research aims to address this gap by focussing on two questions: (1) Which types of
behaviour constitute the top management support for strategic IS projects? and (2) Why do
managers sometimes fail to provide this support? To answer these questions, we analyzed the top
management support during enterprise system implementations in five different organizations. We
conducted cross-case analyses to determine the range of behavioural approaches associated with
this concept. Based on our research questions, we propose a taxonomy that includes six categories
of supportive behaviour of top management, from which potential reasons can be derived to either
support or non-support strategic IS projects.

Abstract. Increasing use of current and developing information technologies (IT) within business
and production processes is a required transformation to survive in the market. However, IT
should be well-managed to be adapted by an organization as a whole. This study proposes a new
model for the assessment of IT use in organizations. The aim is to assist decision making
processes in information technology management through exploring strength and weaknesses of
organization on IT tools and applications. The model has been developed upon a three-folded
structure including academic studies in technology management, best practices which are
developed for control over operations and processes including COBIT, CMMI and ITIL, and
standards about IT management and IT security. The study assists to reveal benefits and
deficiencies of IT use in organizations. It also provides information for decision-makers about IT
value within companies, and demonstrates the effects of best practices and standards over IT use.

Abstract. Patient Centered Design (PCD) is a particular type of User Centered Design (UCD)
where the end-user is a patient that will use an Information and Communications Technology
(ICT) solution for healthcare. It focuses on needs, wants and skills of the product’s primary user
and implies involving end-users in the decision-making and development process of the solution.
e-Therapy aims to provide support to therapy sessions through ICT solutions. In the mental health
arena is being used for specific therapeutic contexts and is an especially difficult environment due
to specificities of the patients' conditions; the physical access to patients is restricted and,
sometimes, not even possible. Thus, a PCD approach can be accomplished through the health
professionals involved, applying some of the most well-known methods of UCD: interviews,
questionnaires, focus groups and participatory design. eSchi is an e-Therapy tool that complements
traditional practices for the cognitive rehabilitation and training of schizophrenic patients and was
successfully developed using a PCD approach.

Abstract. In this paper we present TAM-TAM (Tele Assistance and Monitoring), a tool targeted
to the elderly, impaired and long-term care patients. It provides social support, remote
consultation, remote monitoring and training or rehabilitation group sessions through multi-user
videoconferencing. TAM-TAM relies on a simple and minimalist interface based on accessible
standard web technologies and open video streaming solutions compatible with traditional
(desktop and laptop) PCs as well as last generation tablet PCs. TAM-TAM proves useful to be
deployed at nursing homes, group homes and even private homes for alleviating the patients’
loneliness and depressive status and improving their emotional and social support thanks to their
interaction with their families, social carers or psychologists. On the other hand, it is also used for
providing remote medical services to give advice and determine whether it is needed to take a
further displacement.

Abstract. This article presents a study on the use of the Internet for People with Visual
Impairment (PVI). The objective is to consider a model of survey of the behavior of search and use
of the information in the Web for PVI through the identification of motivators for the process of
search, factors that influence in the interface between the PVI and the contents in the Internet and
elements for the identification of the standardized access. The used method was the revision of
literature with focus in the studies of the Behavior in the information seeking (James Krikelas),
Process of information seeking (Carol C. Kuhlthau) and of the Informational Behavior (Tone D.
Wilson). The validation of the considered model was by means of the accomplishment of an
exploratory research through interviews with blind people that it made possible to collect the
opinions and experiences of these Web users and to identify barriers of access and good
practices. As a result, this work considered a model of survey with composed systemic vision for
necessities/motivators and intervening factors (Inputs), the way the user processes the information
(processing), and the answers, action and reactions front to the accessed information (outputs),
based in the concepts of Universal Access and Accessibility.

Abstract. Biomechanical analysis can be used to scientifically assess the causes of movement
problems, measure progress and validate outcomes. However, the complexity of the data produced
and the training required to use the available biomechanical analysis tools prevents the widespread
understanding of this form of analysis beyond those with a background in biomechanics. This
paper reports on multidisciplinary research, funded by the MRC’s LLHW programme, into the
generation of three-dimensional, dynamic visualisations of biomechanical data and investigation of
their use during functional rehabilitation trials, e.g., post-stroke, knee-joint replacement, and older
adult exercise. The research will test the hypothesis that increased understanding of biomechanical
concepts and measurements through this method of visualisation by both patients and clinicians
will result in better patient outcomes.

Abstract. The offer of interactive television services is becoming more and more frequent in
regular households allowing a more customizable way of watching TV. However, in a multiviewer
environment a truly personalized TV experience could not merely rely on the identification
of the STB that users have at their homes. For this purpose, a non-intrusive user identification
technique is especially relevant, namely when senior viewers are at stake. In this work we are
studying different approaches to perform an adequate identification of senior viewers so they can
benefit from a series of interactive services targeted to their needs. To achieve this aim, a set of
exploratory interviews have been carried out, and based on its results, a prototype with several
identification technologies has been developed. With this prototype and through a set of usability
tests we were able to collect relevant opinions about the type of added value TV services that this
target audience desires. In addition, it was also possible to understand points of view that lead us
to conclude that the user context involves a complex trade-off that influences the choice of the
most suitable identification system.

Abstract. In this paper, we present the on-going work of the iNeighbour TV research project that
aims to promote health care and social interaction among senior citizens, their relatives and
caregivers. The TV set was the device chosen to mediate all the action, since it is a friendly device
and one with which the elderly are used to interact. A study, conducted among the project’s target
audience (TA), using a participatory design approach is addressed in the paper. Its purpose was to
better characterize this type of users; identify relevant features; and evaluate usability and user
interface requirements targeted to television (in an IPTV infrastructure). The analysis of the study
results, which ensured the revision of the project’s features, is also presented along with a
comprehensive description of the validated features. Some of these include: automatic user
recognition system, medication reminder, monitoring system (of deviations from daily patterns),
caregiver support, events planning, audio calls and a set of tools to promote community service.

Abstract. The ongoing Digital Terrestrial Television (DTT) switchover leads to an interesting
opportunity for the implementation of advanced television services. Actually, these services can
even be interactive, since it is foreseen that the required Set-Top Boxes (STB) could be equipped
with an Internet connection. However, among the future clients of DTT there are a large number of
elderly and visually impaired people who can not entirely benefit of these services due to their
physical limitations. Nevertheless, considering that Interactive Television (iTV) services can
contribute to improve life quality of this type of users, it is essential to apply accessibility,
usability and design-oriented guidelines for their development. In this context, this paper
introduces a research related to universal design applied to iTV, being its aim to propose an
advanced and accessible audio description service. In order to perceive the visually impaired
users’ problems and needs, a group of individuals was asked to participate in an interview.

Abstract. The increasing network bandwidth capacity and the diminishing costs of related services
have led to a rising number of applications in the field of Information and Communication
Technology. A special case is applications based on video streaming. Telemedicine can be
highlighted in some scenarios for applying this technology, such as clinical sessions, second
medical opinion, interactive lessons or virtual conferences. These scenarios often imply a
dedicated transmission environment. A restriction in such solutions is the inability to handle
multiple video streams. Thus, this paper presents a low-cost infrastructure for video collaboration
in healthcare and based on open technologies. The proposed infrastructure enables remote
management of simultaneous multiple streams. We also discuss results of experiments held in the
Lauro Wanderley Academic Hospital, Brazil. One of the results is the contribution for teaching
experiences, particularly by allowing students to remotely regard surgical procedures and
providing real-time interaction. Finally, we present new prospects for using the developed
technology on other applications in Telemedicine and Telepresence.

Abstract. Introducing innovative Business Processes in Enterprise functioning is dealt with
according to a specific approach; different from that generally adopted in Business Process
Reengineering projects. This is the case of introducing telemedicine processes in hospitals/clinics
functioning. The main characteristic of the proposed approach is the fact that it doesn’t take into
consideration existing processes but directly examines objectives and vision of to-be processes.
This work is based on two case studies, both related to telemedicine. They respectively concerned
tele-radiology process and tele-consultation process. These case studies allowed us to validate the
proposed approach which was well adapted in both cases.

Abstract. This paper explores the benefits of using immersive and interactive virtual reality
environments to teach Dentistry. We present a tool for educators to manipulate and edit virtual
models. One of the main contributions is that multimedia information can be semantically
associated with parts of the model, through an ontology, enriching the experience; for example,
videos can be linked to each tooth demonstrating how to extract them. The use of semantic
information gives a greater flexibility to the models, since filters can be applied to create
temporary models that show subsets of the original data in a human friendly way. We also explain
how the software was written to run in arbitrary multi-projection environments.

Abstract. Segmentation of echocardiography images presents a great challenge because these
images contain strong speckle noise and artifacts. Besides, most ultrasound segmentation methods
are semi-automatic, requiring initial contour to be manually identified in the images. In this work,
a level set algorithm based on the phase symmetry approach and on a new logarithmic based
stopping function is used to extract simultaneously the four heart cavities in a fully automatic way.
Then, those contours are compared with the ones obtained by four physicians to evaluate the
performance, reliability and confidence for eventual clinical practice. That algorithm evaluation
versus clinicians’ performance is made using several metrics, namely Similarity Region, Hausdorff
distance, Accuracy, Overlap, Sensitivity, and Specificity. We show that the proposed algorithm
performs well, producing contours very similar to the physicians’ ones with the advantage of being
an automatic segmentation technique. The experimental work was based on echocardiography
images of children.

Abstract. The large SNOMED CT (SCT) terminology has gained adoption in the last years.
However, its practical application for coding clinical information is hampered by its complexity
and size. The mechanism of subsets allows for creating clusters of SNOMED CT terms that cover
a particular application or clinical domain. These subsets are usually defined following some sort
of consensual expert-driven process that is effort-intensive. The automated generation of subsets
from clinical document corpora have been proposed elsewhere, but they still require a collection of
documents that is representative for the targeted domain. This paper describes an experiment in
using clinical guidelines’ glossaries as a seed terminology for automatically generating subsets by
traversing SNOMED relationships. Quantitative analysis reveals that traversing patterns need to be
limited, and expert assessments point out that the approach may be viable at least for bootstrapping
the process of elaborating the subsets.

Abstract. Creating digital medical records and retrieve relevant information from them is a
complex task. This complexity is given by the mixture of structured and unstructured information
found in traditional medical records and that such information could be distributed in different data
sources. The main contribution of this paper is the design of an architecture for an Information
Retrieval (IR) system that integrates heterogeneous data sources, with a query interface in natural
language. This system uses Natural Language Processing (NLP) techniques in order to transform
the user query in subqueries to be executed on different data sources, profiting the query
capabilities of Database (DB) and IR technologies. The system is connected to the MedlinePlus
Medical Encyclopedia to extend the results obtained from a query showing relevant articles to it.
In addition, a general application of this design is proposed to address the medical records
management problem in a Cuban hospital.

Abstract. Workflows for surgical procedures have built-in time-out points to minimize
occurrences of unintended faults and omissions during surgeries. They have been recommended in
the best practices of appropriate surgical sub-specialties, as well as the Joint Commission. At these
timeout points, designated team members perform recommended precautionary measures, such as
verifying the accuracy of implants, to ensure unintended mistakes are not made before proceeding
to the next stage. These precautionary measures are usually recorded in paper-based checklists and
retained for a stipulated period of time. We show how these timeout points can be specified as
formal workflow requirements in surgical Electronic Medical Records (S-EMRs).

Abstract. This paper proposes a new method, called the scenario-oriented method, to support the
idea of recording and replaying the healthcare information such that the reporting and decisionsupport
capabilities can be enhanced. In order to play back the changing history of certain
information units, the scenario-oriented method attempts to organize related information and
knowledge elements as a context so that the history of real medical activity can be recorded, and
then be queried as a continuous, on-the-fly, understandable and playing-back information scenario
through replay operations.

Abstract. The increasing demand for superior medical attention, in addition to the low amount of
resources in many of our country's health care institutions, has made patient referral and counterreferral
an important administrative process that begins with a referral from a lower capacity
institution to one with more complex assistance and diagnoses, and ends with a counter-referral to
the original institution, with a specific diagnosis, information on the services administered and
indications for further assistance. Poor communication among hospital professionals can
sometimes result in unnecessary costly referrals and late transfers that can prove deadly. This
article presents an informatic system developed with Free Open Source Software technology that
encourages an efficient usage of Dr. Noel H. Sbarra Specialized Hospital services, to improve the
interaction among professionals of the health care network, in order to increase the capacity of the
primary health care center and, thus, avoid the unnecessary transfer of younger patients.

Abstract. From long to short term planning, the decision processes inherent to surgery theatre
organization are often subject of empiricism. The current hospital information systems available
on Portuguese public hospitals lack a decision support system component that could help achieve
better planning solutions, thus better operational performance of the surgery theatre. Since the
surgery theatre is the biggest hospital budget consumer, the use of surgery related resources and its
intrinsic planning must be carefully studied. We developed a new decision support system for
surgery planning conjointly with one of the largest hospitals in the north of Portugal. As for now,
the goals of the DSS are to improve the planning process and increase policy compliance. We will
enhance this framework by integrating data mining, optimization and simulation techniques in a
way that enables a more accurate representation of the surgery theatre problems’ stochastic nature,
allowing the users to find enhanced planning alternatives.

Abstract. Manchester Triage System is a reliable system of triage in the emergency department of
a hospital. This system when applied to a specific patients’ condition such the pregnancy has
several limitations. To overcome those limitations an alternative triage IDSS was developed in the
MJD. In this approach the knowledge was obtained directly from the doctors’ empirical and
scientific experience to make the first version of decision models. Due to the particular
gynecological and/or obstetrics requests other characteristics had been developed, namely a system
that can increase patient safety for women in need of immediate care and help low-risk women
avoid high-risk care, maximizing the use of resources. This paper presents the arrival flowchart,
the associated decisions and the knowledge acquisition cycle. Results showed that this new
approach enhances the efficiency and the safety through the appropriate use of resources and by
assisting the right patient in the right place.

Abstract. The process of marital dissolution is a crisis that affects both the couple and their
offspring. Many studies have shown how children involved in a marital dissolution could present
less adaptation abilities as well as less healthy live habits. The longer the process, the more serious
become these problems. Therefore, to be able to take preventive actions would be quite useful
towards minimizing the dissolution process impact. This paper aims at supporting the decision of
doctors when deciding about a possible treatment to children involved in a dissolution process
studying the extension of time that the dissolution process spend. Classical statistical techniques as
well as latest machine learning algorithms will be applied in order to predict how long the
dissolution might take and which parameters could be the most significant. The information used
in this study comes from the Spanish government monitorization of the dissolutions during the last
years.

Abstract. Alzheimer’s disease (AD) is the most common cause of dementia, a general term for
memory loss and other intellectual abilities. The Electroencephalogram (EEG) has been used as
diagnosis tool for dementia over several decades. The main objective of this work was to develop
an Artificial Neural Network (ANN) to classify EEG signals between AD patients and Control
subjects. For this purpose two different methodologies and variations were used. The Short time
Fourier transform (STFT) was applied to one of the methodologies and the Wavelet Transform
(WT) was applied to the other methodology. The studied features of the EEG signals were the
Relative Power in conventional EEG bands (delta, theta, alpha, beta and gamma) and their
associated Spectral Ratios (r 1 , r 2 , r 3 and r 4 ). The best classification was performed by the ANN
using the WT Biorthogonal 3.5 with AROC of 0.97, Sensitivity of 92.1%, Specificity of 90.8%
and 91.5% of Accuracy.
Keywords: Alzheimer’s Disease; Electroencephalogram; Artificial Neural Networks; Short Time

Architecture of Health Information Infrastructure
The Case of the United States of America
Andrew Targowski
Western Michigan University, Kalamazoo, MI 49008, USA
andrew.targowski@wmich.edu
Abstract. The Health Infrastructure in the U.S. is called the National Health Information Network
(NHIN) which is composed of regional Health Information Exchange (HIE) hubs. This approach
has been exercised since 2008. However, there is a lack of one top-down comprehensive
architecture of this system, which is being developing by each state individually. This paper
provides the top-down model of such architecture, perhaps the first one which is made. The paper
defines basic components of that system. Also some issues of security and privacy of stored and
exchanged data are disputed. By the end, the paper provides conclusions regarding the issues of its
implementation.
Key words: National Health Information Infrastructure, Health Information Architecture.

A Semantic Web pragmatic approach to develop Clinical
ontologies, and thus Semantic Interoperability, based in HL7
v2.xml messaging
David Mendes and Irene Rodrigues
Universidade de Évora
Abstract. The ISO/HL7 27931:2009 standard intends to establish a global interoperability
framework for Healthcare applications. However, being a messaging related protocol, it lacks a
semantic foundation for interoperability at a machine treatable level has intended through the
Semantic Web. There is no alignment between the HL7 V2.xml message payloads and a meaning
service like a suitable ontology. Careful application of Semantic Web tools and concepts can ease
extremely the path to the fundamental concept of Shared Semantics. In this paper the Semantic
Web and Artificial Intelligence tools and techniques that allow aligned ontology population are
presented and their applicability discussed. We present the coverage of HL7 RIM inadequacy for
ontology mapping and how to circumvent it, NLP techniques for semi automated ontology
population and discuss the current trends about knowledge representation and reasoning that
concur to the proposed achievement.

Abstract. This work aims to create a system of medical diagnosis of the Electrocardiogram
(ECG). The events of the ECG are related with the functioning of the heart and different disorders
of the heart functioning have their own ECG pattern allowing the connection between ECG
patterns and cardiac disorders. For this purpose, we present here an algorithm that detects the P,
QRS and T events of the ECG under MATLAB environment. The algorithm is based in two
techniques. The search for picks and valleys and the search of event using a known patter and the
correlation with ECG signal inside of a previously detected period. Finally the results are
presented and discussed.
Keywords: ECG signal, P QRS and T events detection.

Abstract. The world’s population is aging; we are already facing many socioeconomic challenges
directly related to this problem. These challenges will only tend to grow as time passes. If viable
solutions are not found in time, these challenges will become unbearable as the elderly population
surpasses the younger population. One of the more serious health problems faced by the elderly
are falls that are not succored fast enough. In this paper we discuss the motivations behind our
work and specially our focus on fall detection. We will also present the new Elder Care’s fall
detection system, resultant of our research in the area of statistical regression.

Abstract. Falls are the leading reason for death related accidents in people over 65 years old.
Concerning this situation, it is necessary to develop a viable way of detecting these falls as fast as
possible, so that medical assistance can be provided within useful time. In order for a system of
this kind to work correctly, it must have a low percentage of false positives and a good autonomy.
In this paper we present the research done in order to improve an existing acceleration based
algorithm, which despite being inaccurate is however highly energy efficient. The study of its
improvement was done resorting to the use of cluster analysis and logistic regression. The
resulting algorithm distinguishes itself by being, at the same time, very accurate and having low
energy consumption.

{mano, marga}@ua.pt
Abstract. This work aims to specify and validate a communication framework for healthcare
rescue and emergency services enhanced by personal health monitoring solutions. This framework
aims at presenting a contribution to the evolution of the actual emergency healthcare services
response model toward a national wide communication framework able to enhance emergency
services efficiency and effectiveness by the seamlessly integration with personal health monitoring
solutions. Following a “participatory action research” methodological approach, this work aims to
establish the gap and limitations, verified nowadays, between reactive and proactive emergency
frameworks by identifying major risks and misleading needs, leading to the specification and
discussion of scenarios where emergency responders benefit from the suggested communicating
framework and the value added emerged from it. This paper focuses on the methodological
approach and will describe the most important findings of the first stages: the state of the art, the
diagnosis needs and the research model specification.
Keywords: pervasive healthcare, personal health monitoring, emergency services response and

Abstract. The application of Information Technology (IT) at the medical-hospital services sector,
especially in Brazil, reveals yet slow and incipient, due, especially to the particular characteristics
from this sector. This article presents results from research aiming at analyzing the application, use
and investments in IT in five public hospitals from the municipality of Rio de Janeiro. The field
data were collected using a questionnaire applied to the executives directly connected to the
management of infrastructure and IT of such hospitals. The analysis of data was by means of
descriptive statistics. The research identified weaknesses and problems relative to planning,
selection, implementation and use of such management technology and tools at the researched
hospitals. It was also possible to identify the hospitals which better use and take better advantage
of resources and easiness of this technology so as to facilitate the routine and work processes from
their doctors, patients and directors.

Abstract. The world population is aging and human resources are beginning to become too scarce
to maintain adequate care for an increasingly elderly population. The elderly population requires
continued care, and their relatives cannot answer that need. To ensure that elderly populations
have continuous care, various systems for assistance and monitoring are being researched and
deployed. However there isn't a platform that can integrate all the existing systems. This article
intends to present an initial study performed and the resulting architecture of a complete system
integration platform for applications that cover various areas of biopsychosocial well-being. It has
as its aim to store collected data from different systems using metadata, making a patient medical
history that can be consulted by qualified personnel.

Abstract. The relation between patient and physician in most modern Health Care Systems is
sparse, limited in time and very inflexible. On the other hand, and in contradiction with several
recent studies, most physicians do not rely their patient diagnostics evaluations on intertwined
psychological and social nature factors. Facing these problems and trying to improve the
patient/physician relation we present a mobile health care solution to improve the interaction
between the physician and his patients. The solution serves not only as a privileged mean of
communication between physicians and patients but also as an evolutionary intelligent platform
delivering a mobile rule based system.

Abstract. The medical assistance is an area that is in constant adaptation to the technological
advances in the last decades, specifically in communications and information technology.
Telemedicine has been following the growth of mobile and wireless technologies promoting a
broad medical care and self-care access to patients with difficulties. However, several challenges
still hamper the acceptability of solutions that offer treatment aid. The adaptation of technology to
the patient's everyday life in a noninvasive and secure way are some of those challenges. In order
to minimize these problems, the development of a mobile tool for medical assistance based on a
User-centered approach and communications standards is proposed in this paper.

Abstract. Mobile applications are increasingly used to support nursing work. Specifically, mobile
information and communication technology (MICT) has potential to support treatment initiatives
in patients with skin ulceration or a high risk for their development. We propose a mobile ulcer
monitoring system - mULCER – which serves to control patient’s ulcer status during all stages of
treatment. Additionally it integrates with an electronic health record (EHR) system. mULCER
synchronizes ulcer data with the EHR and provides an everywhere every time support for nurses
on evidence-based advice for prevention, classification, and monitoring different phases of ulcer
healing or prevention. It also increases security and extensiveness of nursing record. The solution
can be operated in stand-alone mode or embedded into an EHR system. It serves as a tool to
integrate nursing care among hospital departments and institutions on an enterprise wide effort to
increase level of health care integration at the point of service. The advantages and disadvantages
of mobile devices for this purpose are also discussed. The paper describes the concepts and
includes a prototype to demonstrate the proposed contribution.

Abstract. This paper develops a founding framework for a comprehensive Obesity Management
Program with Technology (OMPwT). There are two main objectives for such a program, namely –
a) to trigger weight loss and effective behavioral changes that are reinforced through mobile and
online technology support for users (overweight or obese patients) and their mentors (dieticians
and clinicians) and b) to leverage technology to support an efficient workflow process and data
exchange between users, mentors and the healthcare institution. We wish to do this in a local
context of Arab gulf countries and specifically to Qatar. Our research questions are validated in
small focus groups of physicians and dieticians. The proposed methodology covers the
technological design of a comprehensive system that links all key players of the health ecosystem
in a cost effective manner.

Abstract. This article presents the LIFEisGAME project, a serious game that will help children
with ASDs to recognize and express emotions through facial expressions. The game design tackles
one of the main experiential learning cycle of emotion recognition: recognize and mimic (game
mode: build a face). We describe the technology behind the game, which focus on a character
animation pipeline and a sketching algorithm. We detailed the facial expression analyzer that is
used to calculate the score in the game. We also present a study that analyzes what type of
characters children prefer when playing a game. Last, we present a pilot study we have performed
with kids with ASD.
