Como resultado propomos cinco campos de sentido, estruturas transversais e de especificidades químicas, no cruzamento entre filosofia, química e currículo. De posse destas estruturas propomos um diagrama heurístico para a educação química, legitimado pelo confronto com literatura e crítica de experts. Numa segunda etapa da investigação sugerimos, problematizamos e testamos este diagrama como ferramenta formativa, de planejamento, de design e avaliativa de práticas curriculares e didáticas na formação inicial de professores de química.

Com este sistema pretende-se melhorar e facilitar a acessibilidade dos profissionais de saúde aos sinais vitais de pacientes hospitalizados ou mesmo monitorizados no domicílio. Assim, suplanta-se a necessidade de permanecer junto do paciente para vigiar a sua evolução clínica através da monitorização de parâmetros de avaliação do seu estado físico. Este trabalho trata apenas uma parte do sistema de monitorização, encontrando-se integrado num projecto dividido principalmente em três partes: o desenvolvimento dos sensores, a rede wireless para interligar os sensores a uma infra-estrutura e a aplicação de monitorização. Assim, o trabalho proposto consiste na recolha, armazenamento (em Base de Dados) e visualização gráfica dos dados recolhidos pelos sensores colocados nos pacientes (ECG, Oximetria, Frequência Cardíaca, Temperatura e Tensão Arterial). Será, ainda, possível configurar alertas (com base em valores mínimos e máximos) para os indicadores monitorizados, e gerir outra informação sobre os pacientes. De forma a facilitar a utilização do sistema pelos profissionais de saúde, foram desenvolvidos interfaces intuitivos utilizando tecnologias Web, onde um browser é a ferramenta de acesso ao sistema. Para validar a solução desenvolvida foi testado um piloto do projecto, que utiliza os sensores de Temperatura e de ECG, num ambiente real com pacientes reais. Esse teste foi efectuado na Casa de Saúde Guimarães, com a colaboração dos auxiliares de saúde lá presentes. O sistema de monitorização contempla todos os sensores propostos para o sistema, mas até ao momento apenas foram testados os sensores de Temperatura e ECG, uma vez que os restantes ainda se encontram em fase de desenvolvimento. Este documento descreve a implementação de um sistema de monitorização remota de pacientes, abordando as dificuldades encontradas e a forma como foram ultrapassadas, para atingir os objectivos propostos para este projecto.This dissertation describes the development of a real-time remote monitoring system. This system aims at improving and facilitating the accessibility of medical care professionals to the vital signals of hospitalized patients or in their own homes. In this way, the need to physically move to each patient to supervise their clinical condition is supplanted through the monitoring of parameters for remote evaluation of their physical condition. This work just covers a part of the monitoring system, which is integrated in a project divided in three parts: development of sensors, setting up the wireless network to link the sensors to an infrastructure, and a monitoring application. Therefore, the proposed work consists in collecting, storing (in database) and graphically visualizing the data collected from sensors attached to patients (ECG, Oximetry, Heart Rate, Temperature and Blood Pressure). It will be also possible the setting of warnings (based on minimum and maximum values) for monitoring indicators and the management of other information about patients. To make the use of the system for the medical care professionals easier, intuitive interfaces were developed using Web technologies, where an Internet browser is the tool to access the system. In order to validate the developed solution, it was tested in a pilot project, where temperature and ECG sensors were used in a real environment with real patients. This test was carried out in Casa de Saúde de Guimarães, with the help of health professionals present there at the time. The monitoring system includes all sensors proposed to the system, but so far only temperature and ECG sensors have been tested, since the other sensors are still being developed. This document describes the implementation of the remote monitoring patient system, the difficulties found and how they were overcome to achieve the proposed goals for this project

The first systems were developed in U.S.A. and in Canada, in the mid 1960s, but from the early 1970s, a number of systems have been developed in Europe, too, with inspiration from North America (Plant, 1989; Taveira & Campos, 1989; Watts & Ballantine, 1981).

Apparently the robustness of the science paradigm excludes the scientific subjects from this type of support. This is anyway only apparent because the existence of an overwhelming paradigm doesn’t mean that the scientific discourse is unified. Apart from the universal pedagogic existence of the division theme/rheme (Gomes & Costa Pereira, 1991), theme referring to the topic itself and rheme to its explanation, it is important to understand that science has not even a unified thematic discourse but, on the contrary, has different discourses where not only the referents, but also the rules change dramatically. This comes not only from the occasional use of models (analogical and sometimes even pictorial representations (Costa Pereira, 1989 and 1990c)), from the use of specific sign systems (as the symbols and equations in chemistry (Gomes et al., 1989)) but also, and above all, because the epistemologic foundations of most established sciences are, in fact, hybrid. For instance, physics (Harre, 1984) adopts in part the Aristotelian views of substance and also the more modern view of action at a distance and the notion of field which are difficult to make compatible. On the other hand, since the eighteenth century all sciences have evolved, thanks to their reductionism and mechanicism, but nowadays, with the advent of chaos theory (Gleick, 1989) through non-linearity, it is necessary to live also with these ideas. This has important consequences, as for instance, the geometry implied by the latter is very different from the conventional euclidean geometry as it is based on the notions of self-similarity and recursion (fractal geometry).

First, we would like this brief contribution to be considered as a starting point for someone who has just arrived on the Hypertext Planet and not at all as the end point of the research already developed in this domain. Second, we would like to take it as a provocation: this is because on a former occasion (Gomes et al., 1989; Gomes & Costa Pereira, 1990), we rejected the term Hypertext, and proposed another, Holotext, for reasons explained then. It is usual to forgive newcomers a certain boldness even if it is too much as in this case.

First, the cognitive model of the user, which is related to the activity of exploring hypermedia documents. Second, the analysis of the preferences and search strategies of each user as well as the nature and level of the information processed, will lead to hypermedia in which the user diagnostic module must itself be intelligent or, in other words, be capable oflearning. Finally, the system should be able to determine preferential paths for learning in order to direct the student-users.

The lesion was located on the little finger of the right hand and probably resulted from a latent osteomyelitis. It progressed to form extensive necrotic area. No systemic infection was detected and the lesion did not appear to be associated with any trauma.
