Today, business group decision making is an extremely important activity. A considerable number of applications and research have been made in the past years in order to increase the effectiveness of decision making process. In order to support the idea generation process, IGTAI (Idea Generation Tool for Ambient Intelligence) prototype was created. IGTAI is a Group Decision Support System designed to support any kind of meetings namely distributed, asynchronous or face to face. It aims at helping geographically distributed (or not) people and organizations in the idea generation task, by making use of pervasive hardware in a meeting room, expanding the meeting beyond the room walls by allowing a ubiquitous access through different kinds of equipment. This paper focus on the research made to build IGTAI prototype, its architecture and its main functionalities, namely the support given in the different phases of the idea generation meeting.

Devido ao facto de hoje em dia a informação que é processada numa rede informática empresarial, ser cada vez mais de ordem confidencial, torna-se necessário que essa informação esteja o mais protegida possível. Ao mesmo tempo, é necessário que esta a informação esteja disponível com a devida rapidez, para os parceiros certos, num mundo cada vez mais globalizado. Com este trabalho pretende-se efectuar o estudo e implementação da segurança, numa pequena e genérica rede de testes, que facilmente seja extrapolada, para uma rede da dimensão, de uma grande empresa com potenciais ramificações por diversos locais. Pretende-se implementar/monitorização segurança quer externamente, (Internet service provider ISP) quer internamente (activos de rede, postos de trabalho/utilizadores). Esta análise é baseada na localização (local, wireless ou remota), e, sempre que seja detectada qualquer anomalia, seja identificada a sua localização, sendo tomadas automaticamente acções de protecção. Estas anomalias poderão ser geridas recorrendo a ferramentas open source ou comerciais, que façam a recolha de toda a informação necessária, e tomem acções de correcção ou alerta mediante o tipo de anomalia.

Aims: This paper aims to address some of the main possible applications of actual Nuclear Medicine Imaging techniques and methodologies in the specific context of Sports Medicine, namely in two critical systems: musculoskeletal and cardiovascular. Discussion: At the musculoskeletal level, bone scintigraphy techniques proved to be a mean of diagnosis of functional orientation and high sensibility compared with other morphological imaging techniques in the detection and temporal evaluation of pathological situations, for instance allowing the acquisition of information of great relevance in athletes with stress fractures. On the other hand, infection/inflammation studies might be of an important added value to characterize specific situations, early diagnose of potential critical issues – so giving opportunity to precise, complete and fast solutions – while allowing the evaluation and eventual optimization of training programs. At cardiovascular system level, Nuclear Medicine had proved to be crucial in differential diagnosis between cardiac hypertrophy secondary to physical activity (the so called "athlete's heart") and hypertrophic cardiomyopathy, in the diagnosis and prognosis of changes in cardiac function in athletes, as well as in direct - and non-invasive - in vivo visualization of sympathetic cardiac innervation, something that seems to take more and more importance nowadays, namely in order to try to avoid sudden death episodes at intense physical effort. Also the clinical application of Positron Emission Tomography (PET) has becoming more and more widely recognized as promising. Conclusions: It has been concluded that Nuclear Medicine can become an important application in Sports Medicine. Its well established capabilities to early detection of processes involving functional properties allied to its high sensibility and the actual technical possibilities (namely those related with hybrid imaging, that allows to add information provided by high resolution morphological imaging techniques, such as CT and/or MRI) make it a powerful diagnostic tool, claiming to be used on an each day higher range of clinical applications related with all levels of sport activities. Since the improvements at equipment characteristics and detection levels allows the use of smaller and smaller doses, so minimizing radiation exposure it is believed by the authors that the increase of the use of NM tools in the Sports Medicine area should be considered.
