No / Rapid advances in software systems, wireless networks, and embedded devices have led to the development of a pervasive and mobile cyberspace that provides an infrastructure for anywhere/anytime service provisioning in different domains such as engineering, commerce, education, and entertainment. This style of service provisioning enables users to freely move between geographical areas and to continuously access information and conduct online transactions. However, such a high mobility may cause performance and reliability problems during the execution of transactions. For example, the unavailability of sufficient bandwidth can result in failure of transactions when users move from one area (cell) to another. We present a context-aware transaction model that dynamically adapts to the users' needs and execution environments. Accordingly, we develop a new mobility management scheme that ensures seamless connectivity and reliable execution of context-aware transactions during mobility of users. The proposed scheme is designed and developed using a combination of different queuing models. We conduct various experiments in order to show that the proposed scheme optimizes the mobility management process and increases the throughput of context-aware transactions.

[pt] A prevalência global de transtornos de aprendizagem, como dislexia, discalculia, autismo e desordens de atenção, atinge cerca de 10 por cento da população, conforme (BUTTERWORTH, 2018). No Brasil, a falta de um censo específico dificulta a estimativa precisa, mas estima-se que um número significativo de crianças enfrenta desafios de aprendizagem. Este contexto destaca a necessidade de soluções inclusivas, especialmente para auxiliar os professores do Atendimento Educacional Especializado (AEE) dos estudantes dos primeiros anos do Ensino Fundamental I. Esta pesquisa tem como objetivo desenvolver, validar e avaliar uma plataforma pervasiva baseada em tecnologias web. A plataforma tem como finalidade proporcionar uma infraestrutura para a criação e execução de atividades ludificadas, incorporando algoritmos de aprendizado de máquina e realidade estendida. O foco é direcionado a estudantes dos primeiros anos do Ensino Fundamental diagnosticadas com Transtorno do Espectro Autista (TEA) e Transtorno de Déficit de Atenção e Hiperatividade (TDAH). Além disso, busca-se alternativas de custo acessível para manter a plataforma alinhada ao contexto socioeconômico brasileiro. A pesquisa adotou a metodologia Design Science Research (DSR), que se baseia em ciclos interligados e iterativos, onde há a definição do problema, concepção, construção, avaliação e disseminação. Esse método orientou o desenvolvimento da plataforma, garantindo uma abordagem prática e aplicada ao contexto educacional inclusivo. Os resultados da pesquisa culminaram na criação de uma plataforma web abrangente e acessível, integrando algoritmos de aprendizado de máquina e realidade estendida. A plataforma permite aos professores do AEE a personalização de atividades ludificadas que atendam às necessidades específicas de estudantes com TEA e TDAH. A plataforma desenvolvida demonstra promissoras contribuições para a educação inclusiva, oferecendo recursos inovadores e acessíveis. Ao proporcionar uma ferramenta adaptável às demandas socioeconômicas brasileiras, a pesquisa busca contribuir com a igualdade de oportunidades educacionais para estudantes com diferentes necessidades de aprendizagem, o que é garantido por lei através da Lei Brasileira de Inclusão da Pessoa com Deficiência, Capítulo IV – Do Direito à Educação, Parágrafo Único, É dever do Estado, da família, da comunidade escolar e da sociedade assegurar educação de qualidade à pessoa com deficiência, colocando-a a salvo de toda forma de violência, negligência e discriminação. / [en] The global prevalence of learning disorders, such as dyslexia, dyscalculia, autism, and attention disorders, affects approximately 10 percent of the population, according to (BUTTERWORTH, 2018). In Brazil, the lack of a specific census makes precise estimation difficult, but it is estimated that a significant number of children face learning challenges. This context underscores the need for inclusive solutions, especially to assist teachers of students in the early years of Elementary School. This research aims to develop, validate, and evaluate a pervasive web-based platform. The platform aims to provide an infrastructure for the creation and execution of playful activities, incorporating machine learning algorithms and extended reality. The focus is on stundents in the early years of Elementary School diagnosed with Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD). Additionally, affordable alternatives are sought to keep the platform aligned with the Brazilian socioeconomic context. The research adopted the Design Science Research (DSR) methodology, which is based on interconnected and iterative cycles, including problem definition, conception, construction, evaluation, and dissemination. This method guided the development of the platform, ensuring a practical and applied approach to the inclusive educational context. The research results led to the creation of a comprehensive and accessible web platform, integrating machine learning algorithms and extended reality. The platform enables teachers to customize playful activities to meet the specific needs of students with ASD and ADHD. The developed platform shows promising contributions to inclusive education, offering innovative and accessible resources. By providing a tool adaptable to Brazilian socioeconomic demands, the research seeks to contribute equal educational opportunities for students with different learning needs, as guaranteed by law through the Brazilian Law of Inclusion of Persons with Disabilities, Chapter IV – The Right to Education, Sole Paragraph, It is the duty of the State, the family, the school community, and society to ensure quality education for people with disabilities, protecting them from all forms of violence, neglect, and discrimination.

The motivation of the study was to explore the problems of families in South Africa who struggle to manage their children with autism and to find out whether they were receiving appropriate assistance. This was done by assessing the needs of the parents of children with autism by means of semi-structured interviews. Through these interviews, the parents were given the opportunity to express what information or recommendations they would like to have available to them. How the parents view their experience, their feelings about these experiences, and the strategies and actions that they take in order to cope with raising their child with autism, is important information. The aim of the study was to explore the problems South African families have so that this may form the base of information supplied to professionals such as psychologists, social workers, and educators thereby assisting in improving service delivery to parents of children with autism. / Social Work / M.Diac.

A growing number of factors, including costs, technological advancements, ageing populations, and medical errors, are leading industrialized countries to invest in research on alternative solutions to improve their health-care systems and increase patients’ quality of life. Personal health systems (PHS) examplify the use of information and communication technologies that enable a paradigm shift from the traditional hospital-centered healthcare delivery model toward a preventive and person-centered approach. PHS offer the means to monitor a patient’s health using wearable, portable or implantable systems that offer ubiquitous, unobtrusive biodata acquisition, allowing remote monitoring of treatment and access to the patient’s status. Electrical bioimpedance (EBI) technology is non-invasive, quick and relatively affordable technique that can be used for assessing and monitoring different health conditions, e.g., body composition assessments for nutrition. When combined with state-of-the-art advances in sensors and textiles, EBI technologies are fostering the implementation of wearable bioimpedance monitors that use functional garments for personalized healthcare applications. This research work is focused on the development of wearable EBI-based monitoring systems for ubiquitous health monitoring applications. The monitoring systems are built upon portable monitoring instrumentation and custom-made textile electrode garments. Portable EBI-based monitors have been developed using the latest material technology and advances in system-on-chip technology. For instance, a portable EBI spectrometer has been validated against a commercial spectrometer for total body composition assessment using functional textile electrode garments. The development of wearable EBI-based monitoring units using functional garments and dry textile electrodes for body composition assessment and respiratory monitoring has been shown to be a feasible approach. The availability of these measurement systems indicates progress toward the real implementation of personalized healthcare systems. / <p>QC 20170517</p>

Nous avons proposé une approche de clusterisation distribuée en vue de son application au problème de la gestion de groupes dynamiques et pour la sécurisation des échanges. Pour parvenir à cet objectif, une combinaison de critères permettant de sélectionner les noeuds les plus appropriés pour assurer les fonctionnalités de clusterheads a été défini, cette dernière s'appuie sur une topologie virtuelle avec le moins de sauts possible, en évitant ainsi de gaspiller les ressources dans les retransmissions dûes aux collisions. Une fois l'étape de mise au point de l'approche de clusterisation effectuée, une application pour résoudre le problème de la gestion de groupes dynamiques et la sécurisation des échanges a été réalisée. Les performances de notre approche de clusterisation ont été évaluées en terme de messages échangés et d'énergie dépensée par les noeuds du réseau. Les résultats de cette évaluation montrent que notre approche est performante. / The proposed clustering approache divides the network into clusters based on affinity relationships between nodes and two types of keys which are generated by a clusterhead. The first one is shared by a clusterhead and its local members and the second one is shared by the clusterhead and its parent cluster. The proposed algorithm is adaptive according to the limitation of the mobile nodes battery power and to the dynamic network topology changes.The performance evaluation and communication overhead analysis of the proposed algorithm are presented using simulation.

Introdução. O desenvolvimento socioemocional da criança pequena é condicionado por fatores de exposição relacionados ao contexto, cuja presença define a vulnerabilidade da criança para as disfunções socioemocionais. A síntese dos fatores de exposição em marcadores qualitativos de vulnerabilidade favorece a construção de tecnologias de captação de situações de vulnerabilidade e proposição de intervenções que promovam o desenvolvimento socioemocional. Objetivos: Construir marcadores de vulnerabilidade de lactentes para disfunções em seu desenvolvimento socioemocional e realizar sua validação de conteúdo. Método: Pesquisa metodológica de abordagem qualitativa e quantitativa, que teve como referencial teórico o Modelo Bioecológico de Desenvolvimento Humano, e operacionalizada por meio de duas etapas de pesquisa: extração e síntese dos dados, e validação de conteúdo. A identificação dos fatores de exposição ocorreu mediante revisão integrativa, realizada entre abril e agosto de 2016, com critérios definidos de inclusão e exclusão dos estudos, e estratégias sistemáticas de busca. Os dados identificados foram extraídos e submetidos à técnica de análise temática categorial. Os fatores de exposição foram agrupados inicialmente ,conforme a sua semelhança semântica, e foi analisada a relação dessas categorias com os níveis de contexto (Microssistema, Mesossistema, Macrossistema e Exossistema) definidos pelo Modelo Bioecológico. Após, foi analisada a relação das categorias com os elementos de vulnerabilidade da criança para situações adversas em seu desenvolvimento. Da categorização dos fatores de exposição, ocorreu a construção dos marcadores de vulnerabilidade, seus componentes e seus manuais operacionais. Esses conteúdos foram submetidos a duas rodadas de validação de conteúdo com juízes peritos na área de saúde da criança e desenvolvimento infantil. Essa pesquisa foi aprovada pelo Comitê de Ética da Escola de Enfermagem da Universidade de São Paulo por meio do Certificado de Apresentação para Apreciação Ética nº 57933816.8.0000.5392. Resultados: A amostra final de artigos incluídos para a extração dos dados foi de 112.No contexto do Microssistema e Mesossistema, os fatores de exposição foram categorizados como: difilculdades nas relações sustentadoras contínuas; adversidades nas relações familiares e no apoio social, e situação de adoecimento dos cuidadores que influem nos processos proximais. No Exossistema e no Macrossistema os fatores de exposiçãoforam categorizados como: vulnerabilidades sociais dos cuidadores e fragilidades das políticas públicas, que condicionam as condições materiais e sociais da família. A partir dessas categorias, foram construídos oito marcadores de vulnerabilidade, seus 39 componentes e os respectivos manuais operacionais. Participaram da primeira rodada 17 juízes, que tiveram concordância máxima de 100% e mínima de 64% na validação dos marcadores, seus componentes e manuais operacionais. O material foi revisado com as sugestões dos juízes. Na segunda rodada, participaram 11 juízes com concordância máxima de 100% e mínima de 73 %, validando os oito marcadores propostos com seus 36 componentes. Considerações finais: A síntese dos fatores de exposição, apoiada em uma teoria de desenvolvimento abrangente, permitiu a construção de marcadores de vulnerabilidade que tiveram alta aprovação. O consenso obtido pelos juízes permite que essa tecnologia seja testada na prática clínica, para verificar sua capacidade preditiva, com potencial de antecipação dos fatores de exposição subsidiando a prevenção das disfunções socioemocionais. / Introduction: The socioemotional development of infants is conditioned by the exposure to context-related factors, whose presence defines infants vulnerability to socioemotional dysfunctions. The synthesis of exposure factors as qualitative markers of vulnerability holds up the construction of tools, which capture vulnerability situations and promote the socioemotional development. Objectives: To build vulnerability markers of infants for dysfunctions in their socioemotional development and to perform their content validation. Method: Methodological research with qualitative and quantitative approach, based on the Bioecological Model of Human Development, and implemented through two research steps: data collection and synthesis, and content validation. The identification of exposure factors occurred through an integrative review, carried out between April and August 2016, with defined inclusion and exclusion criteria of studies, and systematic search strategies. The identified data were collected, submitted to the categorical thematic analysis technique. The exposure factors were grouped according their semantic similarity and it was analised the relation of categories with the context levels (Microsystem, Mesosystem, Exosystem and Macrosystem) defined by the Bioecological Model. Subsequently, it was analised the relation of categories with the elements of vulnerability of children to adverse situations in their development. From the categorization of the exposure factors, the construction of the vulnerability markers, their components and their operational manuals occurred. These contents were submitted to two rounds of content validation with expert judges in the field of child health and child development. This research was approved by the Ethics Committee of the Nursing School of the University of São Paulo through the Certificate of Presentation for Ethical Appreciation nº 57933816.8.0000.5392. Results: The final sample of included articles for data collection was 112. In the context of the Microsystem and Mesosystem, the exposure factors were categorized as difficulties in the ongoing nurturing relationships; adversities in family relationships and social support, and the caregivers\' illness situation that influence the proximal processes. In the Exosystem and Macrosystem, the exposure factors were categorized as caregivers\' social vulnerabilities and weaknesses of public policies determining the material and social conditions of the family. From these categories, eight vulnerability markers, their 39 components and their operational manuals were built. The first round included 17 judges who had a maximum agreement of 100% and a minimum of 64% in the validation of the markers, their components and operational manuals. The material was revised with the judgessuggestions. In the second round, 11 judges participated with a maximum agreement of 100% and a minimum of 73%, validating the eight proposed markers with their 36 components. Final Considerations: The synthesis of exposure factors supported by a comprehensive development theory allowed the construction of vulnerability markers that had high approval. The consensus obtained by the judges allows that this technology be tested in clinical practice, to verify its predictive capacity, with a potential of anticipation of the exposure factors subsidizing the prevention of socioemotional dysfunctions.
