La médecine traditionnelle indigène peut parfois se poser comme un instrument normatif désignant le malade comme celui qui transgresse l‘ordre établi par les ancêtres sacrés et permet à la maladie d‘advenir. Un tiers malveillant ou un sorcier peuvent également être les causes du désordre physiologique et moral du corps social communautaire. L‘étiologie navajo repose sur deux phénomènes : l‘existence de sociosomas (troubles liés à une mauvaise relation à l‘entourage) et de mouvements d‘exclusion ou d‘inclusion du corps étranger, de la conduite déviante. L‘étude de la figure du malade dans les mythes soulignera l‘aspect normatif des thérapeutiques navajo. Enfin, une réflexion sur la justification idéologique de l‘intégration des pratiques ancestrales au protocole de soin montrera dans quelle mesure la collaboration entre praticiens traditionnels et personnels de santé contribue à stigmatiser le malade comme l‘épitome de toutes les déviances : par rapport à la tradition mais aussi au modèle social dominant.

O setor da construção civil em Portugal sofre atualmente uma crise, como consequência da crise instalada no país. Além disso, a construção tradicional devido à sua rigidez espacial contribuiu para que os edifícios não se pudessem adaptar de uma forma simples, rápida e económica. Para contrabalançar esses factos a industrialização deverá ser encarada como uma das áreas com maior potencial de crescimento no futuro. A possibilidade de conceber um sistema que se adapta às constantes mudanças das necessidades humanas torna-se um dos grandes desafios da indústria da construção civil onde a pré-fabricação terá um papel fundamental. Neste ensaio estuda-se um sistema de divisórias leves amovíveis pré-fabricadas. No primeiro capítulo deste ensaio é elaborada uma síntese de conceitos que estão relacionados com as divisórias leves pré-fabricadas (industrialização e pré-fabricação), aborda-se a avaliação do sistema previsto ao nível da legislação e os passos a dar para verificação da viabilidade do sistema. No segundo capítulo faz-se uma distinção entre os vários tipos de pré-fabricação, definemse as exigências de desempenho e funcionais do sistema, aborda-se o conceito de coordenação modular e das tolerâncias de construção referindo a sua tremenda importância na pré-fabricação. Na parte final deste capítulo abordam-se exaustivamente as exigências de desempenho das paredes interiores não resistentes. No terceiro capítulo desenvolveu-se o sistema. Descrevem-se todos os componentes do sistema e a justificação da sua utilização. Elaboram-se três pré-avaliações: mecânica, acústica e térmica. Definem-se as ligações a serem utilizadas e pormenorizam-se todos os materiais das ligações. É apresentada uma avaliação económica de custos do sistema. Definem-se os procedimentos de: fabricação, transporte, montagem e desmontagem do sistema. No último capítulo apresentam-se as principais conclusões e os possíveis desenvolvimentos futuros.

Preventable visual loss in children is an important public health problem. The critical period of susceptibility to deprivation or abnormal visual experience has been identified since the early 1970s. Preventable visual loss caused by amblyopia (0.3%–4%) and its risk factors such as strabismus (2.1%–4.6%) and uncorrected refractive errors (5%–7.7%) represent an important public health problem. Thus the primary justification for preschool vision screening is the detection of amblyopia or amblyogenic refractive, strabismic, or ocular disease conditions. However in Portugal there has been little investigation regarding prevalence of visual anomalies among school-age children. Data on the prevalence are lacking but are needed for planning vision services. Aims: 1) Determine the prevalence of strabismus; 2) Determine the prevalence of decreased visual acuity; 3) Determine the prevalence of uncorrected refractive error.

All every day activities take place in space. And it is upon this that all information and knowledge revolve. The latter are the key elements in the organisation of territories. Their creation, use and distribution should therefore occur in a balanced way throughout the whole territory in order to allow all individuals to participate in an egalitarian society, in which the flow of knowledge can take precedence over the flow of interests. The information society depends, to a large extent, on the technological capacity to disseminate information and, consequently, the knowledge throughout territory, thereby creating conditions which allow a more balanced development, from the both the social and economic points of view thus avoiding the existence of info-exclusion territories. Internet should therefore be considered more than a mere technology, given that its importance goes well beyond the frontiers of culture and society. It is already a part of daily life and of the new forms of thinking and transmitting information, thus making it a basic necessity essential, for a full socio-economic development. Its role as a platform of creation and distribution of content is regarded as an indispensable element for education in today’s society, since it makes information a much more easily acquired benefit.”…in the same way that the new technologies of generation and distribution of energy allowed factories and large companies to establish themselves as the organisational bases of industrial society, so the internet today constitutes the technological base of the organisational form that characterises the Information Era: the network” (CASTELLS, 2004:15). The changes taking place today in regional and urban structures are increasingly more evident due to a combination of factors such as faster means of transport, more efficient telecommunications and other cheaper and more advanced technologies of information and knowledge. Although their impact on society is obvious, society itself also has a strong influence on the evolution of these technologies. And although physical distance has lost much of the responsibility it had towards explaining particular phenomena of the economy and of society, other aspects such as telecommunications, new forms of mobility, the networks of innovation, the internet, cyberspace, etc., have become more important, and are the subject of study and profound analysis. The science of geographical information, allows, in a much more rigorous way, the analysis of problems thus integrating in a much more balanced way, the concepts of place, of space and of time. Among the traditional disciplines that have already found their place in this process of research and analysis, we can give special attention to a geography of new spaces, which, while not being a geography of ‘innovation’, nor of the ‘Internet’, nor even ‘virtual’, which can be defined as one of the ‘Information Society’, encompassing not only the technological aspects but also including a socio-economic approach. According to the last European statistical data, Portugal shows a deficit in terms of information and knowledge dissemination among its European partners. Some of the causes are very well identified - low levels of scholarship, weak investments on innovation and R&D (both private and public sector) - but others seem to be hidden behind socio-economical and technological factors. So, the justification of Portugal as the case study appeared naturally, on a difficult quest to find the major causes to territorial asymmetries. The substantial amount of data needed for this work was very difficult to obtain and for the islands of Madeira and Azores was insufficient, so only Continental Portugal was considered for this study. In an effort to understand the various aspects of the Geography of the Information Society and bearing in mind the increasing generalised use of information technologies together with the range of technologies available for the dissemination of information, it is important to: (i) Reflect on the geography of the new socio-technological spaces. (ii) Evaluate the potential for the dissemination of information and knowledge through the selection of variables that allow us to determine the dynamic of a given territory or region; (iii) Define a Geography of the Information Society in Continental Portugal.

Dynamic and distributed environments are hard to model since they suffer from unexpected changes, incomplete knowledge, and conflicting perspectives and, thus, call for appropriate knowledge representation and reasoning (KRR) systems. Such KRR systems must handle sets of dynamic beliefs, be sensitive to communicated and perceived changes in the environment and, consequently, may have to drop current beliefs in face of new findings or disregard any new data that conflicts with stronger convictions held by the system. Not only do they need to represent and reason with beliefs, but also they must perform belief revision to maintain the overall consistency of the knowledge base. One way of developing such systems is to use reason maintenance systems (RMS). In this paper we provide an overview of the most representative types of RMS, which are also known as truth maintenance systems (TMS), which are computational instances of the foundations-based theory of belief revision. An RMS module works together with a problem solver. The latter feeds the RMS with assumptions (core beliefs) and conclusions (derived beliefs), which are accompanied by their respective foundations. The role of the RMS module is to store the beliefs, associate with each belief (core or derived belief) the corresponding set of supporting foundations and maintain the consistency of the overall reasoning by keeping, for each represented belief, the current supporting justifications. Two major approaches are used to reason maintenance: single-and multiple-context reasoning systems. Although in the single-context systems, each belief is associated to the beliefs that directly generated it—the justification-based TMS (JTMS) or the logic-based TMS (LTMS), in the multiple context counterparts, each belief is associated with the minimal set of assumptions from which it can be inferred—the assumption-based TMS (ATMS) or the multiple belief reasoner (MBR).
