AMISEC: Leveraging Redundancy and Adaptability to Secure AmI Applications

Security in Ambient Intelligence (AmI) poses too many challenges due to the inherently insecure nature of wireless sensor nodes. However, there are two characteristics of these environments that can be used effectively to prevent, detect, and confine attacks: redundancy and continuous adaptation. In this article we propose a global strategy and a system architecture to cope with security issues in AmI applications at different levels. Unlike in previous approaches, we assume an individual wireless node is vulnerable. We present an agent-based architecture with supporting services that is proven to be adequate to detect and confine common attacks. Decisions at different levels are supported by a trust-based framework with good and bad reputation feedback while maintaining resistance to bad-mouthing attacks. We also propose a set of services that can be used to handle identification, authentication, and authorization in intelligent ambients. The resulting approach takes into account practical issues, such as resource limitation, bandwidth optimization, and scalability

Multipartner alliances among small firms promoted by external managers: Risk and governance mechanisms

External managers may be key to setting up and managing multi-partner alliances (MPAs) among small firms, but their role has not yet been integrated in previous literature on risk and governance structures. This longitudinal matched-pair case study investigates the dynamics between relational and performance risks and control-based and trust-based governance mechanisms, in MPAs promoted and managed by external managers. The integration of external managers allows the identification of different levels of trust and control among partners. This is also the case between such partners and the external manager who controls/trusts, who is controlled/trusted, and how this changes over time. Our results show that trust and control are influenced by both the external actor and partner’s risk perceptions; they also complement each other to manage high performance and relational risks in a dynamic process. We extend prior knowledge by showing that the analysis of control/trust complementarity must take into consideration both partner-partner and partner- manager relationships

ANÁLISE COMPARATIVA DA CARGA DE RESISTÊNCIA ENTRE A NBR 8800 E O EUROCÓDIGO 3 UTILIZANDO O AUTODESK ROBOT E MATHCAD

O presente artigo faz uma abordagem dos diferentes métodos de cálculo utilizando as normas NBR 8800 (2008) e o Eurocódigo 3 (2010) tendo como exemplo uma barra de 6 m de comprimento de um galpão industrial feito em estrutura metálica, modelado dentro do Autodesk Robot, para diferenciar alguns valores de carga resistente, como por exemplo, de compressão, tração e flexão, encontrados através de cálculos dentro do Mathcad para a norma brasileira e pelo Autodesk Robot para a norma europeia. Destaca-se a variação do cálculo resistente de carga a compressão obtido através desses dois meios, demonstrando um valor considerável em comparação as outros valores e explicado, ao final do artigo, os motivos para que este fato ocorra

Influencia del tiempo de uso de las tecnologías de información y comunicación y subprogramas sobre las habilidades informacionales en estudiantes de la Universidad del Zulia

The purpose of this research was to determine the influence of the time of use of technologies of information and communication and related subprograms in the informational skills of students at the University of the Zulia. The research was developed under a descriptive, field based methodology, with a non-experimental design of the trans-sectional type. The population was made up of 95 students in the economic and social sciences program at the LUZ COL. Nucleus. The sample was obtained by means of the Shiffer formula and made up of a group of 52 students in the subprogram of accounting, 15 students of economy, and 18 students of administration. A random sampling stratified by subprograms was used. For the compilation of information 3 instruments were designed, the first one with 8 simple questions, the second one with 29 questions and a Lickert’s scale with four alternatives, and the third one was an observation sheet. The validation of the instrument was made by three experts in the area and there was no the need to realize a reliability test of the instrument provided that they were questionnaires. The analysis of the information was realized by the statistical program SPSS Version 10, in which tests were realized for the calculations of arithmetic averages and standard deviation, as well as analysis of variance, studies of homogeneity and Tukey comparison tests in order to determine the value of the variables in the study. The results obtained showed an influence of the time of use of TIC across the dimension of frequency of hours per week,and informational skills, specifically in the aspects of access and communication of information, and also they revealed that the subprograms do not influence these skills, where students in the program possess high use of these informational skills.El propósito de esta investigación fue determinar la influencia del tiempo de uso de las tecnologías de información y comunicación y subprogramas sobre las habilidades informacionales en estudiantes de la Universidad del Zulia.

CONCEITUAÇÕES SOBRE MOVIMENTOS SOCIAIS E PRÁTICAS POPULARES EM SAÚDE NA ATENÇÃO PRIMÁRIA À SAÚDE: UMA REVISÃO INTEGRATIVA

Objective: This article aims to review and systematize studies on Social Movements and Popular Health Practices in Primary Health Care in Brazil, seeking to identify emerging concepts and ideas. Method: This is a qualitative integrative review of literature published in the years from 2015 to 2020. The bibliographic search was carried out by "Portal de Periódicos CAPES/MEC", using the descriptors: “movimento social”, “movimentos sociais”, “movimento popular”, “movimentos populares”, “movimento comunitário”, “movimentos comunitários”, “prática popular”, “práticas populares, “prática social”, “práticas sociais”, “prática comunitária” e “práticas comunitárias”. Then, we proceeded with the active reading and analysis of the articles qualified for analysis, searching for relevant concepts in the context of social movements. From this, approximations and groupings were made in order to form synthesis concepts. Results: 123 articles were selected for analysis. After the analysis, five synthetic concepts were systematized and divided into five synthetic categories: territory; collective identity; dialogical democratic relations; non-institutionalization; citizenship and autonomy in health. Conclusion: There is a direction in the study for the understanding of social movements and popular health practices as a social group that consists of a set of people who live and share the same territory, relate and organize themselves in a democratic and dialogical way from what they share of collective identities, with the intention of building practices and knowledge that enable the confrontation of social determinants in health presented in their living spaces.Objetivo: O presente artigo objetiva revisar e sistematizar estudos sobre os Movimentos Sociais e as Práticas Populares de Saúde na Atenção Primária à Saúde do Brasil, buscando identificar conceitos e ideias emergentes.

Integrated, reliable and cloud-based personal health record: a scoping review.

Personal Health Records (PHR) emerge as an alternative to integrate patient’s health information to give a global view of patients' status. However, integration is not a trivial feature when dealing with a variety electronic health systems from healthcare centers. Access to PHR sensitive information must comply with privacy policies defined by the patient. Architecture PHR design should be in accordance to these, and take advantage of nowadays technology. Cloud computing is a current technology that provides scalability, ubiquity, and elasticity features. This paper presents a scoping review related to PHR systems that achieve three characteristics: integrated, reliable and cloud-based. We found 101 articles that addressed thosecharacteristics. We identified four main research topics: proposal/developed systems, PHR recommendations for development, system integration and standards, and security and privacy. Integration is tackled with HL7 CDA standard. Information reliability is based in ABE security-privacy mechanism. Cloud-based technology access is achieved via SOA.CONACYT - Consejo Nacional de Ciencia y TecnologíaPROCIENCI
