Physical activity assessment in the general population; instrumental methods and new technologies.

La medición objetiva del movimiento humano y la cuantificación del gasto energético debido a la actividad física es una necesidad identificada tanto en investigación como en clínica. Los métodos de referencia validados y bien definidos (el agua doblemente marcada, la calorimetría directa, la calorimetría indirecta) son caros y prácticamente se limitan a la investigación en el laboratorio. Por lo tanto, en los últimos años, se han desarrollado diferentes dispositivos de medición objetiva que son apropiados para los estudios de campo y clínicos. No hay ningún estándar de oro entre ellos, ya que todos tienen limitaciones. Los podómetros son ligeros, poco costosos, cuentan los pasos y aportan información sobre la actividad física total, pero no sobre el comportamiento y los patrones de actividad física. Los acelerómetros son caros, aportan información sobre patrón, frecuencia e intensidad de la actividad física, pero no sobre el tipo de actividad física. Los podómetros y acelerómetros únicamente recogen información sobre el movimiento del movimiento corporal, pero la validez en la estimación del gasto energético es limitada. La monitorización de la frecuencia cardíaca relaciona intensidad del ejercicio con gasto de energía, pero no aporta información sobre la actividad física. Los dispositivos GPS son portátiles, relativamente asequibles, no invasivos y recogen distancia, velocidad y elevación con hora y lugar exactos, pero quizás estén limitados para la evaluación de movimientos cortos de alta intensidad y elevado gasto energético. Los dispositivos de última generación combinan acelerometría con la medición de variables fisiológicas, comparten las ventajas de los dispositivos individuales y son más precisos. Para el cálculo del gasto energético se aplican algoritmos específicos de la actividad incluidos en el software del fabricante que pueden afectar a los resultados. La mayoría de los dispositivos estiman con mayor precisión el gasto energético a intensidades ligeras y moderadas, pero subestiman el gasto a intensidades muy ligeras y de mayor intensidad.

Educational software in english to the awareness in a preschool education supervised context

Information and communication technologies play an increasingly important role in society, in the sense that all areas and professions make use of digital resources. The school can not be brushed off this reality, aim to create full subjects and integrated in society today. Educational software can be used very early in the education of children, but they must be carefully and monitoring. This article aims to present the results of the use of educational software in English to the awareness of context with children of pre-school education in kindergarten, nursery center Redemptorist Fathers - The smallest fox in White Castle, a 21 group children under 5 years. Early awareness of foreign language such as English can be started with digital multimedia capabilities and various software available on the market. However, the small study described the case reveals some resistance from parents and educators, in the preparation of these to choose and monitor the use of ICT by children, in addition to also highlight the self-interest of the children involved and their learning a few words in English language in different contexts of daily worked. The study opens perspectives on close monitoring needs of such uses and training of educators in the field of use of resources multilingual awareness in pre-school education.

Secure and Privacy-aware Data Collection and Processing in Mobile Health Systems

Healthcare systems have assimilated information and communication technologies in order to improve the quality of healthcare and patient's experience at reduced costs. The increasing digitalization of people's health information raises however new threats regarding information security and privacy. Accidental or deliberate data breaches of health data may lead to societal pressures, embarrassment and discrimination. Information security and privacy are paramount to achieve high quality healthcare services, and further, to not harm individuals when providing care. With that in mind, we give special attention to the category of Mobile Health (mHealth) systems. That is, the use of mobile devices (e.g., mobile phones, sensors, PDAs) to support medical and public health. Such systems, have been particularly successful in developing countries, taking advantage of the flourishing mobile market and the need to expand the coverage of primary healthcare programs. Many mHealth initiatives, however, fail to address security and privacy issues. This, coupled with the lack of specific legislation for privacy and data protection in these countries, increases the risk of harm to individuals. The overall objective of this thesis is to enhance knowledge regarding the design of security and privacy technologies for mHealth systems. In particular, we deal with mHealth Data Collection Systems (MDCSs), which consists of mobile devices for collecting and reporting health-related data, replacing paper-based approaches for health surveys and surveillance. This thesis consists of publications contributing to mHealth security and privacy in various ways: with a comprehensive literature review about mHealth in Brazil; with the design of a security framework for MDCSs (SecourHealth); with the design of a MDCS (GeoHealth); with the design of Privacy Impact Assessment template for MDCSs; and with the study of ontology-based obfuscation and anonymisation functions for health data.

ESL teacher profiles of ICT integration in their classroom practices and assessment activities : a portrait viewed through the lens of some Quebec teachers’ social representations

Abstract : Information and communication technologies (ICTs, henceforth) have become ubiquitous in our society. The plethora of devices competing with the computer, from iPads to the Interactive whiteboard, just to name a few, has provided teachers and students alike with the ability to communicate and access information with unprecedented accessibility and speed. It is only logical that schools reflect these changes given that their purpose is to prepare students for the future. Surprisingly enough, research indicates that ICT integration into teaching activities is still marginal. Many elementary and secondary schoolteachers are not making effective use of ICTs in their teaching activities as well as in their assessment practices. The purpose of the current study is a) to describe Quebec ESL teachers’ profiles of using ICTs in their daily teaching activities; b) to describe teachers’ ICT integration and assessment practices; and c) to describe teachers’ social representations regarding the utility and relevance of ICT use in their daily teaching activities and assessment practices. In order to attain our objectives, we based our theoretical framework, principally, on the social representations (SR, henceforth) theory and we defined most related constructs which were deemed fundamental to the current thesis. We also collected data from 28 ESL elementary and secondary school teachers working in public and private sectors. The interview guide used to that end included a range of items to elicit teachers’ SR in terms of ICT daily use in teaching activities as well as in assessment practices. In addition, we carried out our data analyses from a textual statistics perspective, a particular mode of content analysis, in order to extract the indicators underlying teachers’ representations of the teachers. The findings suggest that although almost all participants use a wide range of ICT tools in their practices, ICT implementation is seemingly not exploited to its fullest potential and, correspondingly, is likely to produce limited effects on students’ learning. Moreover, none of the interviewees claim that they use ICTs in their assessment practices and they still hold to the traditional paper-based assessment (PBA, henceforth) approach of assessing students’ learning. Teachers’ common discourse reveals a gap between the positive standpoint with regards to ICT integration, on the one hand, and the actual uses of instructional technology, on the other. These results are useful for better understanding the way ESL teachers in Quebec currently view their use of ICTs, particularly for evaluation purposes. In fact, they provide a starting place for reconsidering the implementation of ICTs in elementary and secondary schools. They may also be useful to open up avenues for the development of a future research program in this regard.

Large scale underground energy storage for renewables integration: general criteria for reservoir identification and viable technologies.

The increasing integration of renewable energies in the electricity grid contributes considerably to achieve the European Union goals on energy and Greenhouse Gases (GHG) emissions reduction. However, it also brings problems to grid management. Large scale energy storage can provide the means for a better integration of the renewable energy sources, for balancing supply and demand, to increase energy security, to enhance a better management of the grid and also to converge towards a low carbon economy. Geological formations have the potential to store large volumes of fluids with minimal impact to environment and society. One of the ways to ensure a large scale energy storage is to use the storage capacity in geological reservoir. In fact, there are several viable technologies for underground energy storage, as well as several types of underground reservoirs that can be considered. The geological energy storage technologies considered in this research were: Underground Gas Storage (UGS), Hydrogen Storage (HS), Compressed Air Energy Storage (CAES), Underground Pumped Hydro Storage (UPHS) and Thermal Energy Storage (TES). For these different types of underground energy storage technologies there are several types of geological reservoirs that can be suitable, namely: depleted hydrocarbon reservoirs, aquifers, salt formations and caverns, engineered rock caverns and abandoned mines. Specific site screening criteria are applicable to each of these reservoir types and technologies, which determines the viability of the reservoir itself, and of the technology for any particular site. This paper presents a review of the criteria applied in the scope of the Portuguese contribution to the EU funded project ESTMAP – Energy Storage Mapping and Planning.

Enabling Human Centric Smart Campuses via Edge Computing and Connected Objects

Early definitions of Smart Building focused almost entirely on the technology aspect and did not suggest user interaction at all. Indeed, today we would attribute it more to the concept of the automated building. In this sense, control of comfort conditions inside buildings is a problem that is being well investigated, since it has a direct effect on users’ productivity and an indirect effect on energy saving. Therefore, from the users’ perspective, a typical environment can be considered comfortable, if it’s capable of providing adequate thermal comfort, visual comfort and indoor air quality conditions and acoustic comfort. In the last years, the scientific community has dealt with many challenges, especially from a technological point of view. For instance, smart sensing devices, the internet, and communication technologies have enabled a new paradigm called Edge computing that brings computation and data storage closer to the location where it is needed, to improve response times and save bandwidth. This has allowed us to improve services, sustainability and decision making. Many solutions have been implemented such as smart classrooms, controlling the thermal condition of the building, monitoring HVAC data for energy-efficient of the campus and so forth. Though these projects provide to the realization of smart campus, a framework for smart campus is yet to be determined. These new technologies have also introduced new research challenges: within this thesis work, some of the principal open challenges will be faced, proposing a new conceptual framework, technologies and tools to move forward the actual implementation of smart campuses. Keeping in mind, several problems known in the literature have been investigated: the occupancy detection, noise monitoring for acoustic comfort, context awareness inside the building, wayfinding indoor, strategic deployment for air quality and books preserving.

Um retrato da área de Neurociência e comportamento no Brasil

A neurociência compreende o estudo do controle neural das funções vegetativas, sensoriais e motoras; dos comportamentos de locomoção, reprodução e alimentação; e dos mecanismos da atenção, memória, aprendizagem, emoção, linguagem e comunicação. Tem, portanto, uma importante área de interface com a Psicologia. Dentre seus objetivos, a neurociência busca esclarecer os mecanismos das doenças neurológicas e mentais por meio do estudo do sistema nervoso normal e patológico. Sua evolução no Brasil tem ocorrido desde meados do século passado, e seu desenvolvimento foi incentivado pela criação de sociedades científicas específicas. O presente artigo relata esse desenvolvimento e descreve os principais grupos atuantes na neurociência brasileira.

Sociedade da informação: avanços e retrocessos no acesso e no uso da informação

The Information Society (IS) may be taken as a geopolitical organization which started after the Third Industrial Revolution, having direct impact on the use of information and Information and Communication Technologies (ICT). The expression arose as techno-social paradigm change in the post-industrial society, aiming to use information as currency to the society-in-progress at that time. In Brazil it has become stronger with the Programa Sociedade da Informacao no Brasil-Livro Verde, lunched by the Ministerio da Ciencia e Tecnologia, in September 2000 without any discussion with the civil society to formulate the main document. Our main goal in this article is to discuss the Information Society in contemporary times, and also the organized and conscious use of information, looking for key-concepts to a better understanding of it, from some topics as digital inclusion-exclusion to the use of digital informational resources.

Multiple layers of information are added to the cultural products, signalling the formation of a new type of knowledge necessary for the critical and understanding of the works. The article reflects on this process, focusing on cultural information present on the Internet.

Contribui????es do governo eletr??nico para a reforma administrativa e a governan??a no Brasil

O artigo investiga as contribui????es da pol??tica de governo eletr??nico para a reforma administrativa e a governan??a no Brasil. A pesquisa baseou-se na opini??o de informantes-chave dos quatro setores que atuam no e-gov: setor p??blico, iniciativa privada, terceiro setor e academia. Concluiu-se que as tecnologias de informa????o e comunica????o (TIC) podem ser a principal ferramenta para as iniciativas de moderniza????o do Estado, sendo ressalvado que o e-governo n??o pode ser visto como panac??ia para as reformas: o uso de tecnologias deveria caminhar em paralelo com outras medidas governamentais, nos campos pol??tico e econ??mico, por exemplo. Embora tenha sido reconhecido o potencial das TIC, o governo eletr??nico ainda n??o se encontra inserido com a ??nfase necess??ria na agenda governamental brasileira, de modo a contribuir decisivamente para a reforma administrativa e a governan??a.

O papel do governo eletr??nico no fortalecimento da governan??a do setor p??blico

As novas Tecnologias da Informa????o e Comunica????o (TIC), entre as quais se destacam a internet, as redes de computadores, a transmiss??o via sat??lite e a telefonia m??vel, criaram condi????es para o surgimento de Sociedades do Conhecimento. Nesse contexto, o Estado, por interm??dio do governo eletr??nico, ?? o principal instrumento de que os cidad??os disp??em atualmente para enfrentar os desafios impostos pela globaliza????o, por meio de intera????es in??ditas da sociedade, empresas e governos. O objetivo deste trabalho foi estabelecer rela????es entre a governan??a do setor p??blico e o governo eletr??nico, partindo-se de um marco referencial te??rico das duas ??reas de estudo. Para tanto, foram delineados seus escopos e limites de atua????o, instituindo-se v??nculos, de acordo com a????es do Governo Eletr??nico brasileiro: certifica????o digital; Portal da Transpar??ncia; vota????o eletr??nica; preg??es eletr??nicos e Portal da Previd??ncia Social. Conclui-se que, apesar dos avan??os recentes observados pela an??lise de v??rias dimens??es da governan??a, baseados em iniciativas de governo eletr??nico aqui inventariadas, ainda h?? muito que fazer em dire????o ?? inclus??o social no Brasil, assim como em outros pa??ses. As TIC podem vir a ser um poderoso agente de inclus??o digital, apoiando a governan??a com a cria????o de espa??os virtuais para participa????o democr??tica e di??logo c??vico e expans??o da participa????o em tomada de decis??o coletiva, promovendo a igualdade e a cidadania.
