A web-based intelligent tutoring system on teaching and learning electrical project

The Information and Communication Technology (ICT) provide new strategies for disseminating information and new communication models in order to change attitudes and human behaviour concerning to education. Nowadays the internet is crucial as a means of communication and information sharing. To education or tutorship will be required to use ICT, supported on the internet, to establish the communication of teacher-student and student-student, disseminating the content of the subjects, and as a way of teaching and learning process. This paper presents an intelligent tutor that aims to be a tool to support teaching and learning in the field of the electrical engineering project.

VirtualECare: group decision supported by idea generation and argumentation

In the last years there has been a considerable increase in the number of people in need of intensive care, especially among the elderly, a phenomenon that is related to population ageing (Brown 2003). However, this is not exclusive of the elderly, as diseases as obesity, diabetes, and blood pressure have been increasing among young adults (Ford and Capewell 2007). As a new fact, it has to be dealt with by the healthcare sector, and particularly by the public one. Thus, the importance of finding new and cost effective ways for healthcare delivery are of particular importance, especially when the patients are not to be detached from their environments (WHO 2004). Following this line of thinking, a VirtualECare Multiagent System is presented in section 2, being our efforts centered on its Group Decision modules (Costa, Neves et al. 2007) (Camarinha-Matos and Afsarmanesh 2001).On the other hand, there has been a growing interest in combining the technological advances in the information society - computing, telecommunications and knowledge – in order to create new methodologies for problem solving, namely those that convey on Group Decision Support Systems (GDSS), based on agent perception. Indeed, the new economy, along with increased competition in today’s complex business environments, takes the companies to seek complementarities, in order to increase competitiveness and reduce risks. Under these scenarios, planning takes a major role in a company life cycle. However, effective planning depends on the generation and analysis of ideas (innovative or not) and, as a result, the idea generation and management processes are crucial. Our objective is to apply the GDSS referred to above to a new area. We believe that the use of GDSS in the healthcare arena will allow professionals to achieve better results in the analysis of one’s Electronically Clinical Profile (ECP). This attainment is vital, regarding the incoming to the market of new drugs and medical practices, which compete in the use of limited resources.

Spatial dynamics of team sports exposed by Voronoi diagrams

Team sports represent complex systems: players interact continuously during a game, and exhibit intricate patterns of interaction, which can be identified and investigated at both individual and collective levels. We used Voronoi diagrams to identify and investigate the spatial dynamics of players' behavior in Futsal. Using this tool, we examined 19 plays of a sub-phase of a Futsal game played in a reduced area (20 m(2)) from which we extracted the trajectories of all players. Results obtained from a comparative analysis of player's Voronoi area (dominant region) and nearest teammate distance revealed different patterns of interaction between attackers and defenders, both at the level of individual players and teams. We found that, compared to defenders, larger dominant regions were associated with attackers. Furthermore, these regions were more variable in size among players from the same team but, at the player level, the attackers' dominant regions were more regular than those associated with each of the defenders. These findings support a formal description of the dynamic spatial interaction of the players, at least during the particular sub-phase of Futsal investigated. The adopted approach may be extended to other team behaviors where the actions taken at any instant in time by each of the involved agents are associated with the space they occupy at that particular time.

Metástases temporais: a propósito de um caso clínico

A metastização óssea para a cabeça e pescoço é rara. Em 20-35% dos casos, pode ser a primeira manifestação de uma neoplasia oculta. No caso específico do osso temporal, as metástases são originárias, mais frequentemente, da mama, pulmão, rim, próstata e estômago. Apresenta-se o caso clínico de uma doente, do sexo feminino, 71 anos, com Diagnóstico de Carcinoma Ductal tipo Cribiforme na mama esquerda, tendo sido submetida a mastectomia total, quimioterapia e radioterapia. À observação apresentava um quadro clínico de otalgia esquerda, associada a paralisia facial da hemiface ipsilateral, sem outros sintomas otológicos. Foi-lhe diagnosticada Otite Média Crónica agudizada, tendo sido medicada e pedida Tomografia Computorizada ao Ouvido Esquerdo, que demonstrou exuberante espessamento dos tecidos moles epicranianos temporo-parieto-occipitais à esquerda com extensão ao canal auditivo externo do mesmo lado. Por agravamento da sintomatologia, foi internada no Serviço de Otorrinolaringologia deste hospital para administração de terapêutica endovenosa, tendo-se admitido a hipótese diagnóstica de Otite Externa Maligna. Por manutenção do quadro, apesar de terapêutica optimizada, foi submetida a intervenção cirúrgica onde foi efectuada biopsia temporal, tendo sido diagnosticado lesão metastática por carcinoma invasivo da mama.

Vasculites Sistémicas Primárias da Infância

As vasculites sistémicas constituem um grupo de doenças, pouco frequentes na infância, caracterizadas por inflamação e necrose vascular. A sua tradução clínica é heterogénea, condicionada pelo tipo de vaso e orgão afectados. Recentemente foi proposta uma classificação das vasculites em idade pediátrica, que tem em conta a dimensão dos vasos envolvidos, sendo também validados critérios de diagnóstico para os tipos mais frequentes em crianças. A presente revisão tem como objectivo abordar os tipos mais frequentes de vasculites na infância, suas manifestações clínicas, diagnóstico e terapêutica.
