O nosso trabalho tem como objectivo apresentar uma organização de um Vocabulário de Base no Ensino Primário em Angola, numa perspectiva de ensino e aprendizagem do Português, em contexto angolano, com vista à contribuição e melhoria das estratégias do ensino e aprendizagem do vocabulário, não só em sala de aula, como também a sua aplicação em materiais didácticos, como em dicionários de aprendizagem. Apresentámos, de uma forma sucinta, a organização e o contexto de desenvolvimento dos Sistema de Educação de Angola, com a finalidade de fazer um enquadramento dos planos de estudo do Ensino Primário. Foram importantes as abordagens sobre os conceitos básicos de Lexicologia, Lexicografia, léxico, cultura, vocabulário, Lexicultura. Usámos o software Hyperbase como metodologia para o levantamento, selecção e organização dos vocábulos nos manuais escolares. O software serviu para análise dos dados dos textos, de modo a propor um dicionário de aprendizagem, conforme o modelo apresentado no final do trabalho.

Semantic relations extraction from unstructured information for domain ontologies enrichment

Based in internet growth, through semantic web, together with communication speed improvement and fast development of storage device sizes, data and information volume rises considerably every day. Because of this, in the last few years there has been a growing interest in structures for formal representation with suitable characteristics, such as the possibility to organize data and information, as well as the reuse of its contents aimed for the generation of new knowledge. Controlled Vocabulary, specifically Ontologies, present themselves in the lead as one of such structures of representation with high potential. Not only allow for data representation, as well as the reuse of such data for knowledge extraction, coupled with its subsequent storage through not so complex formalisms. However, for the purpose of assuring that ontology knowledge is always up to date, they need maintenance. Ontology Learning is an area which studies the details of update and maintenance of ontologies. It is worth noting that relevant literature already presents first results on automatic maintenance of ontologies, but still in a very early stage. Human-based processes are still the current way to update and maintain an ontology, which turns this into a cumbersome task. The generation of new knowledge aimed for ontology growth can be done based in Data Mining techniques, which is an area that studies techniques for data processing, pattern discovery and knowledge extraction in IT systems. This work aims at proposing a novel semi-automatic method for knowledge extraction from unstructured data sources, using Data Mining techniques, namely through pattern discovery, focused in improving the precision of concept and its semantic relations present in an ontology. In order to verify the applicability of the proposed method, a proof of concept was developed, presenting its results, which were applied in building and construction sector.

Portuguese plain architecture: history opening a closed sequence

The paper will address George Kubler’s Portuguese Plain Architecture [PPA] (1972) and its effect in Portuguese architectural practice. Kubler’s philosophy of art history implied that closed sequences of objects could be opened by several reasons. Thus, it will be argued that there is an effect upon Portuguese architecture post 1974, that is apparent by the reemergence of some of the form classes treated by Kubler. This was mostly achieved through the popularity of Kubler’s book within architectural practice, scholarship and moreover by the establishment of the term “Plain Architecture” in portuguese architectural vocabulary. Plain Architecture of the seventeenth and eighteenth centuries shared some qualities with the architecture to be built in post‑revolutionary Portugal, most importantly the effect that could be achieved with low budget buildings that were responding to a situation of crisis, and simultaneously exhaled aristocratic sparsity. The connection of PPA with the ideological attributes of early modernism and the political context of the time catalysed the reemergence of a new order of Portuguese Plain that resonates still in contemporary architecture.

Prevalência da C.trachomatis entre homens que fazem sexo com homens (HSH) que frequentam um centro clínico comunitário alternativo em Barcelona

RESUMO - Enquadramento: A infeção por Chlamydia trachomatis (CT) é considerada um grave problema de Saúde Pública. É causa de infeções sintomáticas tanto no homem como na mulher, bem como, de infeções assintomáticas que podem ter consequências muito graves a longo prazo. A presença de CT sem tratamento aumenta o risco de transmissão do vírus da imunodeficiência humana. Existem vários estudos publicados de prevalência da CT por todo o mundo, no entanto, estudos de prevalência da CT em populações assintomáticas, envolvendo homens que fazem sexo com homens (HSH) são raros na Europa. Assim, o presente estudo, ao estimar a prevalência e ao descrever as caraterísticas epidemiológicas e de conduta dos HSH, pretende contribuir para o plano de ação contra as IST´s e VIH na Catalunha, através de estratégias concretas para deteção e prevenção da CT. Métodos: Trata-se de um estudo observacional, transversal de prevalência da CT em HSH utentes de um serviço comunitário em Barcelona, com recurso a técnicas de diagnóstico de biologia molecular e a um questionário. Durante Março e Junho de 2015, foram recrutados 200 voluntários de um serviço comunitário em Barcelona que foram testados para CT e NG em três locais anatómicos através de uma PCR em tempo real utilizando o ensaio Anyplex™ CT/NG Real-time Detection. Resultados: O presente estudo permitiu uma caraterização da situação atual quanto á prevalência e aos fatores de risco associados á infeção por CT em HSH. A prevalência nesta população específica foi de 12,6% e os fatores risco associados foram o facto de serem VIH e praticarem sexo anal insertivo/recetivo com parceiro estável. Conclusões: Os resultados obtidos reforçam a necessidade do desenvolvimento de estratégias adequadas de controlo e prevenção da CT nesta população de risco, tais como: rastreios frequentes e tratamento dos casos positivos para quebrar a cadeia de transmissão, promoção da saúde, educação e notificação dos parceiros sexuais. Também demonstram a importância destes rastreios nos três locais anatómicos: uretra, reto e faringe.

International partner selection Indian technical textile market

Due to a combination of a vast agricultural industry and a tremendously growing technical textile industry, Ludvig Svensson identified India as target market for possible expansion through domestic production and supply. However, Svensson needed additional information about the industry structure and key players. Therefore, this project focused on a detailed analysis of the technical textile market and its players by following the international partner selection process. Thereby, five key players were identified as potential partners, as well as the need for additional research to determine alternative entry modes, as the market does not currently seem to be receptive for Svensson products.

Hand gesture recognition for human computer interaction : a comparative study of different image features

Hand gesture recognition for human computer interaction, being a natural way of human computer interaction, is an area of active research in computer vision and machine learning. This is an area with many different possible applications, giving users a simpler and more natural way to communicate with robots/systems interfaces, without the need for extra devices. So, the primary goal of gesture recognition research is to create systems, which can identify specific human gestures and use them to convey information or for device control. For that, vision-based hand gesture interfaces require fast and extremely robust hand detection, and gesture recognition in real time. In this study we try to identify hand features that, isolated, respond better in various situations in human-computer interaction. The extracted features are used to train a set of classifiers with the help of RapidMiner in order to find the best learner. A dataset with our own gesture vocabulary consisted of 10 gestures, recorded from 20 users was created for later processing. Experimental results show that the radial signature and the centroid distance are the features that when used separately obtain better results, with an accuracy of 91% and 90,1% respectively obtained with a Neural Network classifier. These to methods have also the advantage of being simple in terms of computational complexity, which make them good candidates for real-time hand gesture recognition.

Digital manipulatives as scaffolds for preschoolers’ language development

The study reported here aims at contributing to a deeper understanding of the educational possibilities offered by digital manipulatives in preschool contexts. It presents a study carried with a digital manipulative to enhance the development of lexical knowledge and language awareness, which are relevant language abilities for formal literacy learning. The study took place in a Portuguese preschool, with a class of 20 five-year-olds in collaboration with the teacher. The digital manipulative supported the construction of multiple fictional worlds, motivating children's verbal interactions, and the playing of words and sound games, thus contextualizing the learning of an extensive collection of vocabulary and language awareness abilities. The degree of engagement and involvement that the manipulative provided in supporting children’s imaginative play as well as the imitation, in their own play, of the playful pedagogical interventions that the teacher had designed, shows the importance of well- designed materials that support a child-centered learning model. As such, it sustains a discussion on the potential of digital manipulatives to enhance fundamental language development in the preschool years. Further, the study highlights the importance of multidisciplinary teams in the creation of innovative pedagogical materials.

Abnormalities in the processing of emotional prosody from single words in schizophrenia

Background: Abnormalities in emotional prosody processing have been consistently reported in schizophrenia and are related to poor social outcomes. However, the role of stimulus complexity in abnormal emotional prosody processing is still unclear. Method: We recorded event-related potentials in 16 patients with chronic schizophrenia and 16 healthy controls to investigate: 1) the temporal course of emotional prosody processing; and 2) the relative contribution of prosodic and semantic cues in emotional prosody processing. Stimuli were prosodic single words presented in two conditions: with intelligible (semantic content condition—SCC) and unintelligible semantic content (pure prosody condition—PPC). Results: Relative to healthy controls, schizophrenia patients showed reduced P50 for happy PPC words, and reduced N100 for both neutral and emotional SCC words and for neutral PPC stimuli. Also, increased P200 was observed in schizophrenia for happy prosody in SCC only. Behavioral results revealed higher error rates in schizophrenia for angry prosody in SCC and for happy prosody in PPC. Conclusions: Together, these data further demonstrate the interactions between abnormal sensory processes and higher-order processes in bringing about emotional prosody processing dysfunction in schizophrenia. They further suggest that impaired emotional prosody processing is dependent on stimulus complexity.
