Desenvolvimento de uma ferramenta colaborativa na área da gestão da informação/conhecimento para aplicação numa unidade de cuidados na comunidade

O presente projeto surgiu da necessidade de um instrumento de trabalho na área da gestão da informação / conhecimento a aplicar na Unidade de Cuidados na Comunidade dos Carvalhos (UCCC) que, pela sua estrutura de trabalho por projeto, abrange diversos grupos de utilizadores com perfis e necessidades específicas. Rapidamente assumiu maior dimensão, pois ao seu ponto de partida se conjugaram as oportunidades de utilização das tecnologias de informação na área da saúde, a divulgação da Unidade assim como a divulgação de informação sobre saúde e a interação com os utilizadores. O processo implicou a aplicação das metodologias de Investigação Ação e de Gestão de Projetos, resultando na criação e publicação de um espaço Web. Com o Content Management System (CMS) Joomla foi construído o Site UCC Carvalhos, que faculta simultaneamente informação sobre saúde, oportunidade de aconselhamento especializado e personalizado e permite a organização da documentação interna da Unidade referida. Nesta fase de início de vida do site estabeleceu-se como temáticas prioritárias a desenvolver a informação sobre a UCCC e o seu funcionamento assim como o projeto “Companhia das Barriguinhas”, mais concretamente a Preparação para o Parto e Parentalidade. O desenvolvimento deste projeto superou as expectativas de todos os elementos envolvidos, pois para além de permitir obter resposta às necessidades identificadas, permitiu também experimentar as metodologias referidas de forma integrada e aprofundar temáticas como a gestão da informação e conhecimento, o papel das tecnologias de informação e comunicação na Saúde e o papel do cidadão na utilização das mesmas no sentido de uma autonomia responsável na gestão da sua Saúde.

Effects of early life permethrin exposure on spatial working memory and on monoamine levels in different brain areas of pre-senescent rats

Pesticide exposure during brain development could represent an important risk factor for the onset of neurodegenerative diseases. Previous studies investigated the effect of permethrin (PERM) administered at 34 mg/kg, a dose close to the no observable adverse effect level (NOAEL) from post natal day (PND) 6 to PND 21 in rats. Despite the PERM dose did not elicited overt signs of toxicity (i.e. normal body weight gain curve), it was able to induce striatal neurodegeneration (dopamine and Nurr1 reduction, and lipid peroxidation increase). The present study was designed to characterize the cognitive deficits in the current animal model. When during late adulthood PERM treated rats were tested for spatial working memory performances in a T-maze-rewarded alternation task they took longer to choose for the correct arm in comparison to age matched controls. No differences between groups were found in anxiety-like state, locomotor activity, feeding behavior and spatial orientation task. Our findings showing a selective effect of PERM treatment on the T-maze task point to an involvement of frontal cortico-striatal circuitry rather than to a role for the hippocampus. The predominant disturbances concern the dopamine (DA) depletion in the striatum and, the serotonin (5-HT) and noradrenaline (NE) unbalance together with a hypometabolic state in the medial prefrontal cortex area. In the hippocampus, an increase of NE and a decrease of DA were observed in PERM treated rats as compared to controls. The concentration of the most representative marker for pyrethroid exposure (3-phenoxybenzoic acid) measured in the urine of rodents 12 h after the last treatment was 41.50 µ/L and it was completely eliminated after 96 h.

How to feel "in love" with Math - a MOOC experience

In the past few years we have witnessed the fast development of distance learning tools such as Open Educational Resources (OER) and Massive Open Online Courses (MOOCs). This paper presents the “Mathematics without STRESS” MOOC Project, which is a cooperation between four schools from the Polytechnic Institute of Oporto (IPP). The concepts of MOOC and their quickly growing popularity are presented and complemented by a discussion of some MOOC definitions. The process of the project development is demonstrated by focusing on used MOOC structure, as well as the several types of course materials produced. At last, is presented a short discussion about problems and challenges met throughout the project. It is also our goal to contribute for a change in the way as teaching and learning Mathematics is seen and practiced nowadays.

How to feel “in love" with math: a MOOC experience

In the past few years we have witnessed astonishing developments on distance learning tools, in particular on Open Educational Resources (OER) such as Massive Open Online Courses (MOOC). In this paper we present the “Mathematics without STRESS”, a MOOC Project, which has been a collaborative volunteer effort that brought together professors, from four schools of the Polytechnic Institute of Oporto (IPP), in Portugal. Some concepts directly associated with MOOC and their quickly growing popularity are complemented with a discussion of some particular MOOC characterizations. The design process of this project is revealed by focusing on the MOOC structure we used, as well as on the several types of course materials that were produced. At last, we undertake a short discussion about some of the problems, achievements and challenges met throughout this project development, giving a special attention to the motivational aim of this work - hoping to contribute to a change in the way of teaching and learning Mathematics is seen and practiced nowadays.

Early physiological and biochemical responses of rice seedlings to low concentration of microcystin-LR

Microcystin-leucine and arginine (microcystin- LR) is a cyanotoxin produced by cyanobacteria like Microcystis aeruginosa, and it’s considered a threat to water quality, agriculture, and human health. Rice (Oryzasativa) is a plant of great importance in human food consumption and economy, with extensive use around the world. It is therefore important to assess the possible effects of using water contaminated with microcystin-LR to irrigate rice crops, in order to ensure a safe, high quality product to consumers. In this study, 12 and 20-day-old plants were exposed during 2 or 7 days to a M. aeruginosa extract containing environmentally relevant microcystin-LR concentrations, 0.26–78 lg/L. Fresh and dry weight of roots and leaves, chlorophyll fluorescence, glutathione S-transferase and glutathione peroxidase activities, and protein identification by mass spectrometry through two-dimensional gel electrophoresis from root and leaf tissues, were evaluated in order to gauge the plant’s physiological condition and biochemical response after toxin exposure. Results obtained from plant biomass, chlorophyll fluorescence, and enzyme activity assays showed no significant differences between control and treatment groups. How- ever, proteomics data indicates that plants respond to M. aeruginosa extract containing environmentally relevant microcystin-LR concentrations by changing their metabolism, responding differently to different toxin concentrations. Biological processes most affected were related to protein folding and stress response, protein biosynthesis, cell signalling and gene expression regulation, and energy and carbohydrate metabolism which may denote a toxic effect induced by M. aeruginosa extract and microcystin- LR. Theimplications of the metabolic alterations in plant physiology and growth require further elucidation.

Os efeitos da intervenção no reconto e nas narrativas de experiência pessoal em crianças de idade pré-escolar

As competências narrativas emergem desde cedo, e vão sendo adquiridas ao longo do desenvolvimento da criança. No entanto não significa que se desenrolam do mesmo modo em todos as crianças pois crianças com dificuldades na produção narrativa poderão ter necessidade de um ensino específico e estruturado. Sendo a narrativa um aspeto importante da linguagem, é fundamental agir o mais cedo possível para prevenir futuros problemas, tanto no percurso académico como social. Tendo por base as questões em torno da produção narrativa, o presente estudo tem como objetivo compreender a influência da intervenção narrativa no reconto e nas narrativas de experiência pessoal em oito crianças do pré-escolar (5/6 anos), estando um dos participantes diagnosticado com uma condição do espetro do autismo. Ao longo do estudo, todos os participantes foram sendo avaliados pela escala Narrative Language Measures durante 10 sessões e quanto à intervenção narrativa denominada Campeões de histórias consistiu em 21 sessões com duração média de 25 minutos. Neste estudo recorremos ao delineamento experimental de linha de base múltipla, o que nos permitiu analisar o desempenho de cada participante ao longo do tempo. Os resultados revelaram que através da intervenção narrativa houve um aumento na cotação dos testes da escala em todos os participantes, inclusive na criança com condição do espetro autista, e que esses se mantiveram sempre acima dos níveis basais após um período de duas semanas sem intervenção. Deste modo, podemos concluir que a intervenção narrativa produziu efeitos relevantes quer no reconto, quer nas narrativas de experiência pessoal dos participantes e que se apresenta como uma intervenção económica, rápida e eficaz.
