Security architecture for mobile E-health applications in medication control

The use of Radio Frequency Identification technology (RFID) in medical context enables not only drug identification, but also a rapid and precise identification of patients, physicians, nurses or any other health caregiver. Combining RFID tag identification with structured and secured Internet of Things (IoT) solutions enable ubiquitous and easy access to medical related records, while providing control and security to all interactions. This paper defines a basic security architecture, easily deployable on mobile platforms, which would allow to establish and manage a medication prescription service in mobility context making use of electronic Personal Health Records. This security architecture is aimed to be used with a mobile e-health application (m-health) through a simple and intuitive interface, supported by RFID technology. This architecture, able to support secured and authenticated interactions, will enable an easy deployment of m-health applications. The special case of drug administration and ubiquitous medication control system, along with the corresponding Internet of Things context, is used as a case study. Both security architecture and its protocols, along with a general Ambient Assisted Living secure service for medication control, is then analyzed in the context of the Internet of Things.FEDER Funds through the Programa Operacional Fatores de Competitividade - COMPETE and by National Funds through the FCT - Fundação para a Ciência e a Tecnologia (Portuguese Foundation for Science and Technology) within project FCOMP-01-0124-FEDER-022674

Computer vision intelligent approaches to extract human pose and Its activity from image sequences

The purpose of this work is to develop computational intelligence models based on neural networks (NN), fuzzy models (FM), support vector machines (SVM) and long short-term memory networks (LSTM) to predict human pose and activity from image sequences, based on computer vision approaches to gather the required features. To obtain the human pose semantics (output classes), based on a set of 3D points that describe the human body model (the input variables of the predictive model), prediction models were obtained from the acquired data, for example, video images. In the same way, to predict the semantics of the atomic activities that compose an activity, based again in the human body model extracted at each video frame, prediction models were learned using LSTM networks. In both cases the best learned models were implemented in an application to test the systems. The SVM model obtained 95.97% of correct classification of the six different human poses tackled in this work, during tests in different situations from the training phase. The implemented LSTM learned model achieved an overall accuracy of 88%, during tests in different situations from the training phase. These results demonstrate the validity of both approaches to predict human pose and activity from image sequences. Moreover, the system is capable of obtaining the atomic activities and quantifying the time interval in which each activity takes place.info:eu-repo/semantics/publishedVersio

A Decade-Long Commitment to Antimicrobial Resistance Surveillance in Portugal

Antimicrobial resistance (AMR) is a worldwide problem with serious health and economic repercussions. Since the 1940s, underuse, overuse, and misuse of antibiotics have had a significant environmental downside. Large amounts of antibiotics not fully metabolized after use in human and veterinary medicine, and other applications, are annually released into the environment. The result has been the development and dissemination of antibiotic-resistant bacteria due to many years of selective pressure. Surveillance of AMR provides important information that helps in monitoring and understanding how resistance mechanisms develop and disseminate within different environments. Surveillance data is needed to inform clinical therapy decisions, to guide policy proposals, and to assess the impact of action plans to fight AMR. The Functional Genomics and Proteomics Unit, based at the University of Trás-os-Montes and Alto Douro (UTAD) in Vila Real, Portugal, has recently completed 10 years of research surveying AMR in bacteria, mainly commensal indicator bacteria such as enterococci and Escherichia coli from the microbiota of different animals. Samples from more than 75 different sources have been accessed, from humans to food-producing animals, pets, and wild animals. The typical microbiological workflow involved phenotypic studies followed by molecular approaches. Throughout the decade, 4,017 samples were collected and over 5,000 bacterial isolates obtained. High levels of AMR to several antimicrobial classes have been reported, including to β-lactams, glycopeptides, tetracyclines, aminoglycosides, sulphonamides and quinolones. Multi-resistant strains, some relevant to human and veterinary medicine like extended-spectrum β-lactamase-producing E. coli and vancomycin-resistant enterococci, have been repeatedly isolated even in non-synanthropic animal species. Of particular relevance are reports of AMR bacteria in wildlife from natural reserves and endangered species. Future work awaits as this threatening yet unsolved problem persists

Sensores de gás para domótica

Mestrado em Engenharia de MateriaisO presente trabalho propôs-se comparar sensores semicondutores de gases baseados em diferentes morfologias do óxido de SnO2 para a deteção de monóxido de carbono, recorrendo aos métodos de síntese hidrotermal e deposição eletroforética. Este estudo visa entender a importância da morfologia na resposta elétrica e sensibilidade de um sensor semicondutor. Por alteração do precursor de Sn obtiveram-se partículas de SnO2 de diferentes morfologias (nanopartículas e nanobastonetes). Para além da morfologia estas nanoestruturas comportam-se diferentemente em termos de grau de cristalinidade, de distribuição, de tamanho de partícula e de estabilidade coloidal. Estas diferença a nível de suspensão afetam marcadamente a deposição eletroforética e a qualidade dos filmes obtidos. A deposição dos filmes é facilitada para as nanopartículas. Sensores de SnO2 que combinam síntese hidrotermal das nanopartículas com deposição eletroforética do óxido sensor apresentam valores de sensibilidade de 11 e 3 para concentrações de 2000 e 5000 ppm respetivamente.The main goal of this work is the comparison of semiconductor gas sensors based on different morphologies of SnO2 for the carbon monoxide detection, using techniques such hydrothermal synthesis and electrophorectic deposition. This work compromises to study the importance of morphology in the electric response and sensibility of a semiconductor sensor. By changing the precursor Sn, SnO2 particles were obtained with differents morphologies (nanoparticles and nanorods). This different structures present different cristalinity, particle size distribution and colloidal stability. For each suspension, the results of electrophorectic deposition and the quality of the obtained films were very distinct. Nanoparticles Deposition is easier when compared to nanorods. SnO2 sensors that combine hydrothermal synthesis and electrophorectic deposition presente values of sensibility of 11 and 3 to 2000 and 5000 ppm of carbon monoxide concentration

Visualização de Dados do Exame Nacional Brasileiro do Ensino Médio: VisDadosEnem

Artigo apresentado no I Workshop de Informação, Dados e Tecnologia, realizado entre nos dias 04 e 06 de setembro de 2017, na cidade de Florianópolis (SC), no Auditório do Espaço Físico Integrado (EFI) da Universidade Federal de Santa Catarina (UFSC).Hoje em dia, baseado na quantidade de dados disponíveis surgem situações em que a visualização da informação torna-se fundamental para o entendimento e interpretação dos dados. Dentro deste contexto, este estudo tem como objetivo relacionar e explorar, através de técnicas de visualização, dados abertos educacionais em um contexto multidisciplinar. Para tal, foi desenvolvido uma aplicação Web para visualização de dados do exame nacional Brasileiro do ensino médio (ENEM). Neste estudo utilizou-se os microdados do ENEM, a partir do portal Brasileiro de dados abertos. Como resultado das análises comparativas realizadas sobre os dados, por estados, regiões e tipos de escolas, observou-se quais estados obtiveram as maiores e menores médias do ENEM em relação as médias nacionais. Por exemplo, no estado de Santa Catarina os alunos oriundos de escolas particulares obtiveram 12.70% acima da média nacional para este tipo de escola e a menor média de idade dos alunos inscritos correspondendo a 21,6 anos de idade. A aplicação Web de visualização possibilitou uma análise comparativa sobre o grande conjunto de dados e a exploração de possibilidades de visualização que seriam dificilmente possíveis de realizar por meio de representações tradicionais.Nowadays, based on the amount of available data, there are situations in which the information visualization becomes fundamental for the understanding and interpretation of the data. In this context, the study aims to relate and explore, through visualization techniques, open educational data in a multidisciplinary context. For that, a Web application was developed for data visualization of the Brazilian national high school exam (ENEM). In this study, the ENEM microdata was used, from the Brazilian open data portal. As a result of the comparative analyzes performed on the data, by states, regions and types of schools, it was observed which states obtained the highest and lowest averages of ENEM in relation to national averages. For example, in the state of Santa Catarina, students from private schools obtained 12.70% above the national average for that type of school and the lowest average age of enrolled students corresponding to 21.6 years old. The visualization Web application made possible a comparative analysis on the large dataset and the exploration of visualization possibilities that would be difficult to perform through traditional representations

Orientador : Prof. Dr. Vagner Gularte CortezDissertação (mestrado) - Universidade Federal do Paraná, Setor de Ciências Biológicas, Programa de Pós-Graduação em Botânica. Defesa: Curitiba,30/01/2017Inclui referências : f. 167-189Resumo: Agaricales reúne fungos que produzem basidiomas predominantemente agaricoides, mas também abrangem formas gasteroides, secotioides, cifeloides, poroides, clavarioides e corticioides. No Brasil estão registradas atualmente 926 espécies, com numerosos registros na região sul, principalmente nos estados do Rio Grande do Sul e Paraná. No Paraná, mais de 600 espécies são mencionadas na literatura, porém os estudos se concentram em áreas de Floresta Ombrófila Mista e Densa. Com o objetivo de contribuir ao conhecimento da micobiota da Floresta Estacional Semidecidual do oeste do Paraná, o presente trabalho apresenta resultados do levantamento de Agaricales na região. As coletas foram realizadas entre Janeiro e Dezembro de 2015 no Parque Estadual de São Camilo, e Reserva Particular do Patrimônio Natural Fazenda Açú remanescente de Floresta Estacional Semidecidual, localizados nos municípios de Palotina e Terra Roxa, respectivamente. O estudo compreendeu análise morfológica (macroscópica e microscópica) e identificação dos espécimes, segundo a literatura especializada. Os espécimes foram preservados no Herbário do Campus Palotina (HCP) e os holótipos no Herbário do Departamento de Botânica (UPCB), ambos da Universidade Federal do Paraná. Foram analisados 578 espécimes, representando 76 espécies, distribuídas em 49 gêneros de 16 famílias. Clitocella pallescens e Panaeolus silvaticus são propostas como novas espécies para a ciência. Clitocella himantiigena é proposta nova combinação. Copelandia mexicana, Crepidotus mexicanus, Tricholosporum tropicale e Tubaria bispora são novos registros para a América do Sul. O gênero Clitocella é citado pela primeira vez no Brasil. Agaricus ochraceosquamulosus, Clitocella himantiigena, Gymnopilus chrysopellus, Leucoagaricus coerulescens, Marasmiellus atrosetosus e Rhodocybe galerinoides são novos registros para o Brasil. Agaricus endoxanthus, Crepidotus crocophyllus, Hohenbuehelia mastrucata, Lepiota lilacea, Leucocoprinus straminellus, Mycena euspeirea, Mycena holoporphyra, Pleurotus opuntiae e Psilocybe yungensis são novos registros para o Estado do Paraná. Outras 29 são novas ocorrências para Floresta Estacional Semidecidual do estado do Paraná. O grande número de espécimes coletadas assim como o de espécies identificadas demonstra que esse é um grupo bastante diverso nos estudos de diversidade de Fungos s.l. e também amplamente diverso nesse ecossistema. A continuidade desse estudo com ênfase em grupos pouco estudados deve revelar novos registros de espécies ainda desconhecidas para a região assim como novidades taxonômicas.

In Brazil, 926 species belonging to the Agaricales have been reported, with numerous records from South Brazil, especially from Rio Grande do Sul and Paraná States. From the State of Paraná, about 600 species are reported, although most of the studies surveyed areas of Mixed and Dense Ombrophilous Forests in the State. Aiming to survey the mycobiota from the Seasonal Semideciduous Forests from the western region of Paraná State, the present focused on the Agaricales. Fieldwork was carried on from January to December 2015, in two localities: Parque Estadual de Sâo Camilo, municipality of Palotina, and Reserva Particular do Patrimônio Natural Fazenda Açú, municipality of Terra Roxa. The investigation comprised morphological (macro-and microscopical) of the basidiomata, and taxonomic identification. Specimens were preserved at the Herbário of Campus Palotina (HCP) and holotypes at the Herbário of Departamento de Botânica (UPCB), both at the Universidade Federal do Paraná. All were 578 specimens were identified, comprising 76 species, 49 genera and 16 families. Clitocella pallescens and Panaeolus silvaticus are proposed as new species. Clitocella himantiigena is a new combination and the genus Clitocella is reported from the first time in Brazil. Copelandia mexicana, Crepidotus mexicanus, Tricholosporum tropicale, and Tubaria bispora are new records from South America. Agaricus cf. ochraceosquamulosus, Clitocella himantiigena, Gymnopilus chrysopellus, Leucoagaricus coerulescens, Marasmiellus atrosetosus and Rhodocybe galerinoides are new records from Brazil. Agaricus endoxanthus, Crepidotus crocophyllus, Hohenbuehelia mastrucata, Lepiota lilacea Leucocoprinus straminellus, Mycena euspeirea, Mycena holoporphyra, Pleurotus opuntiae and Psilocybe yungensis are new records from Paraná State. Other 29 taxa are reported for the first time in the Seasonal Semideduous Forest of western Paraná.
