HOsT: Towards a Low-Cost Fog Solution via Smart Objects to Deal with the Heterogeneity of Data in a Residential Environment.

With the fast and unstoppable development of technology, the amount of available technological devices and the data they produce is overwhelming. In analyzing the context of a smart home, a diverse group of intelligent devices generating constant reports of its environment information is needed for the proper control of the house. Due to this demand, many possible solutions have been developed in the literature to assess the need for processing power and storage capacity. This work proposes HOsT (home-context-aware fog-computing solution)-a solution that addresses the problems of data heterogeneity and the interoperability of smart objects in the context of a smart home. HOsT was modeled to compose a set of intelligent objects to form a computational infrastructure in fog. A publish/subscribe communication module was implemented to abstract the details of communication between objects to disseminate heterogeneous information. A performance evaluation was carried out to validate HOsT. The results show evidence of efficiency in the communication infrastructure; and in the impact of HOsT compared with a cloud infrastructure. Furthermore, HOsT provides scalability about the number of devices acting simultaneously and demonstrates its ability to work with different devices.

FORESAM-FOG Paradigm-Based Resource Allocation Mechanism for Vehicular Clouds.

The Intelligent Transport Systems (ITS) has the objective quality of transportation improvement through transportation system monitoring and management and makes the trip more comfortable and safer for drivers and passengers. The mobile clouds can assist the ITS in handling the resource management problem. However, resource allocation management in an ITS is challenging due to vehicular network characteristics, such as high mobility and dynamic topology. With that in mind, we propose the FORESAM, a mechanism for resources management and allocation based on a set of FOGs which control vehicular cloud resources in the urban environment. The mechanism is based on a more accurate mathematical model (Multiple Attribute Decision), which aims to assist the allocation decision of resources set that meets the period requested service. The simulation results have shown that the proposed solution allows a higher number of services, reducing the number of locks of services with its accuracy. Furthermore, its resource allocation is more balanced the provided a smaller amount of discarded services.

Da apreensão de informações aos itinerários terapêuticos de homens diante de suspeita ou com diagnóstico de infecções sexualmente transmissíveis. A internet em pauta / From information's assimilation to men's therapeutic itineraries of men with or suspect of sexually transmitted diseases. The internet in focus

Resumo Explora-se como os homens, diante de suspeita ou diagnóstico de doenças sexualmente transmissíveis (DSTs), apreendem as informações sobre elas e como tal apreensão se articula com seus itinerários terapêuticos. O estudo é parte de pesquisa sobre acesso de homens a diagnóstico e tratamento de DSTs (exceto HIV/aids) e envolveu 18 entrevistas individuais em profundidade, com pacientes em seguimento em serviços de saúde, e quatro grupos focais, com trabalhadores do ramo de serviços. Todos acessaram informações sobre DSTs por meio de palestras e campanhas, sobretudo sobre aids. As informações assumem significados distintos, na ausência de sinais/sintomas e na vigência da DST: o sentimento de invulnerabilidade cede espaço para dúvidas, temores e vergonha. O sigilo propiciado pela internet a torna importante fonte de informações quando da suspeita/diagnóstico de DST, mas seu conteúdo reproduz o discurso biomédico, não fornecendo respostas que aplaquem julgamentos morais e o estigma das DSTs. Os homens elegem o médico como principal referência de cuidado, justificando a persistência na peregrinação que fizeram para obter atendimento. Aliada à oferta de serviços, parece oportuno que as informações transitem para uma comunicação em saúde que dialogue com as necessidades da população e que a inclusão digital seja sinônimo de cidadania digital.

Abstract This paper aims to explore how men, in the presence of suspect or diagnosis, can assimilate information about sexually transmitted diseases (STD) and how this comprehension can integrate with their therapeutic itineraries. This study is part of a larger research about the access to diagnosis and treatment of STD (excluding HIV/Aids). It involved 18 individual in-depth interviews with men attending in health services, and four focus groups with service workers. All participants have access to information on STD by lectures and campaigns, especially about Aids. Information has different meanings when there is lack of signs/symptoms or when there is the presence of STD's: feeling of invulnerability or doubts, fears and shame, respectively. The secrecy that internet can provide became a prime source of information when there is a suspicion/diagnosis of STD, but this information can reproduce the biomedical discourses, and do not give answers able to mitigate moral judgments and STD's stigma. Men choose the doctor as the mainly way of treatment and care, which justifies the persistence to look for health care services. Besides the range of services, it seems seasonable that information follows health communication, according to the population's needs, and digital inclusion can be synonymous with digital citizenship.

Supply and usage of hemodynamic services in the state of Rio de Janeiro, Brazil.

OBJECTIVE: To analyze the supply of equipment and procedures inherent to public hemodynamic services in the State of Rio de Janeiro, Brazil. METHODS: We conducted an exploratory study based on official data banks: AMS survey of IBGE, CNES, AIH and APAC, and ANS. The examination period of the supply was from 1999 to 2009, and of the use, from 2008 to October 2012. RESULTS: Since 1999 there has been a growth in the acquisition of hemodynamic equipment. The private sector concentrates most of the offer, but has been reducing its availability to the Unified Health System (SUS). The ratio of the equipment and the population exceeds that of some rich countries. On the supply side, there was, in Rio de Janeiro, in 2009, a rate of 4.1 units per million inhabitants, higher than in Brazil as a whole, of 3.4; however, when considering only the offer for the SUS (SUS), the values are similar, 1.6 and 1.5. CONCLUSION: The procedures of interventional cardiology grew between 2008 and 2011 in Rio de Janeiro, but the majority of public hospitals have reduced production and the private have increased it, resulting in the referral of SUS users to be submitted to procedures great distances from home.

Supply and usage of hemodynamic services in the state of Rio de Janeiro, Brazil / Oferta e utilização de serviços de hemodinâmica no estado do Rio de Janeiro, Brasil

Objective: The paper analyzes the supply and the utilization of hemodynamic services in Rio de Janeiro, Brazil. Methods: It's an exploratory study that uses data obtained from Brazilian official databases. The period of supply analysis was from 1999 to 2009, and of utilization was from 2008 to October 2012. Results: Since 1999 there is a growth of hemodynamic equipment purchase. The private sector concentrates most of the supply, but it has been reducing its availability to SUS. The rate between population and equipment in Brazil exceeds the ones of some rich countries. In the sense of supply, there are in 2009, a supply rate of 1,4 equipments for 1 million inhabitants in RJ state, larger than brazilian rate, of 3,4 but the rates are similar for public customers. Conclusion: Interventional cardiology procedures have improved in the state, but in a different way. And this is because the public hospitals at Rio de Janeiro have mostly reduced their production, while the private ones have increased their production. The observed result is the SUS users performing their procedures at great distances. .

Prevalence of Chlamydia trachomatis in asymptomatic Brazilian military conscripts.

BACKGROUND: Few data are available on the prevalence and risk factors for Chlamydia trachomatis infection among young men in Brazil. OBJECTIVES: To assess prevalence and risk factors for C. trachomatis infection in male military conscripts. METHODS: In 2000, 627 young men recruited for military service in Goiania, Goias, Brazil, were enrolled in this cross-sectional study. Participants completed a demographic and sexual risk behavior questionnaire, and urine samples were screened for C. trachomatis by polymerase chain reaction. RESULTS: The prevalence of chlamydial infection among asymptomatic conscripts was 5.0% (95% confidence interval [CI], 3.3-7.3). In multivariate analysis, failure to use condoms (odds ratio [OR](adjusted) 5.3; 95% confidence interval [CI], 1.2-23.4; P = 0.028) and having more than 2 sexual partners in the last 2 months (OR(adjusted) 2.6; 95% CI, 1.1-6.9; P = 0.049) were significantly associated with positivity for C. trachomatis. CONCLUSIONS: A substantial number of asymptomatic young male military recruits were infected with C. trachomatis, and risk factors for this infection were related to sexual behavior. Further research is required to determine if routine screening may be considered as a strategy to reduce prevalence among this population.
