Deadline Missing Prediction Through the Use of Milestones

Distributed Real-Time Thread is an important concept for distributed real-time systems. Distributed Threads are schedulable entities with an end-to-end deadline that transpose nodes, carrying their scheduling context. In each node, the thread will be locally scheduled according to a local deadline, which is defined by a deadline partitioning algorithm. Mechanisms for predicting the missing of deadlines are fundamental if corrective actions are incorporated for improving system quality of service. In this work, a mechanism for predicting missing deadlines is proposed and evaluated through simulation. In order to illustrate the main characteristics of the proposed mechanism, experiments will be presented taking into account different scenarios of normal load and overload. Simulations show that the deadline missing prediction mechanism proposed presents good results for improving the overall performance and availability of distributed systems

Sharing renewable energy in a network sharing context

This paper studies the performance gains resulting from the sharing of energy and network resources in the case of co-located base stations of different mobile network operators, powered by photovoltaic panels, and equipped with energy storage. Three configurations are considered for base station cooperation. The first one assumes two non-cooperating base stations, each one exploiting its own power system and serving its own customers, hence with no sharing. The second considers a shared power system, but no cooperation in customer service. The third looks at cooperation in both energy production and service provisioning, since only one base station handles all customers when traffic is low. Using an analytical modeling framework, we compute performance metrics for the three cases, and we show that significant gains are possible in the case of energy and network sharing.TRUEpu

Uso de rede sociais e autoimagem em adolescentes: uma revisão narrativa

As redes sociais são ferramentas de comunicação que têm se tornado cada vez mais presentes no cotidiano dos adolescentes. Essa fase do ciclo vital gera inseguranças e questionamentos, tornando esse público mais suscetível à grande quantidade de informações que lhes são expostas, podendo acarretar complicações na sua autoimagem. O objetivo deste estudo foi descrever os principais impactos do uso das redes sociais na autoimagem dos adolescentes. Realizou-se uma revisão narrativa onde foram consultados materiais bibliográficos nacionais e internacionais, como livros, artigos científicos e dissertações utilizando-se os descritores:  adolescencia, rede social e autoimagem. Como resultados, percebeu-se que o uso de redes sociais interfere na percepção subjetiva que os jovens têm sobre si mesmos em vários aspectos: físicos, comportamentais, alimentares e sociais. Além disso, a busca extrema para atingir padrões disseminados nas redes sociais leva ao desenvolvimento ou agravamento de sintomas e transtornos psicológicos. Conclui-se que a forma e a frequência na qual as redes sociais são usadas refletem significativamente na autoimagem do adolescente, são altamente reforçadas pelo grupo social e podem acarretar sintomas ou transtornos psiquiátricos. Destaca-se a importância da família e escola para o desenvolvimento de uma autoimagem saudável

Assessment of impacts on ecosystem services provided by geodiversity in highly urbanised areas: a case study of the Taubaté Basin, Brazil

This work presents a method to identify, to evaluate and to quantify the losses of the offer of ecosystem services provided by geodiversity, using as a case study the Taubaté Basin region, a highly urbanized portion of southeastern São Paulo State, Brazil. Our method considers not only the qualitative analysis of the abiotic as- pects, but also the historical and cultural context, in which the geodiversity elements are crucial for local economy development. The method is based on: i) Qualitative evaluation and definition of six Essential Geodiversity Variables (EGVs), used as the basis for the identification of 53 ecosystem services distributed into four functions: regulating, supporting, provisioning, and cultural; ii) Definition of land use categories based on two land use maps elaborated in order to compare the transformation occurred in the region between 1986 and 2016; iii) Quantification and evaluation of the impacts on the offer of ecosystem services caused by land use transformations occurred in region in a 30–year gap. The results showed that anthropogenic action is the main factor that alter the availability of local services, with emphasis on the supply of water, soils and mineral resources, and its potentially influence on the quality of life of certain species. We reinforce the view that public policies on land management and planning should consider the ecosystem assessment, as it provides evidence to propose actions to mitigate impacts and for environmental compensation, favoring the sustainable use of re- sources by society.The authors would like to thank CAPES for the Academic Mobility Program PDSE Scholarship / Process Nr. 88,881.135227 / 2016–01 and for the PhD research scholarship in Brazil awarded to the first author

Evaluation of neuromotor development by means of the Harris Infant Neuromotor Test

Objective: To investigate the neuromotor development of at-risk children between three and 12 months of life, administering the Brazilian version of the Harris Infant Neuromotor Test (HINT).Method: A longitudinal study, with 78 children and 76 parents/guardians discharged from a neonatal intensive care unit in Fortaleza-CE/Brazil. Two instruments were administered: HINT and a socioeconomic questionnaire, between July/2009 to August/2010. Data from 55 preterm and 23 term children were analyzed. Results: The final mean scores ranged from 14.6 to 25.2 and from 11.2 to 24.7, for preterm and term, respectively, showing that 91% of children demonstrated good neuromotor performance; seven premature infants showed alterations which led to the referral of three children to a specialized clinic for examination and diagnostics.Conclusion: The test allowed nurses to assess infant development, identify deviations early, and plan interventions

O lugar ocupado pela assistência fisioterapêutica: representações sociais de trabalhadores com DORT

INTRODUÇÃO: Os distúrbios osteomusculares relacionados ao trabalho (DORT) articulam-se diretamente à realização de atividades ocupacionais e às condições de trabalho. OBJETIVO: O artigo origina-se de uma pesquisa qualitativa que analisou as representações sociais da assistência fisioterapêutica entre trabalhadores portadores de Distúrbios Osteomusculares Relacionados ao Trabalho (DORT), frequentadores do Centro de Referência em Saúde do Trabalhador (CEREST), pelo Departamento de Saúde do Trabalhador (DSAT), Juiz de Fora (MG). MATERIAIS E MÉTODOS: O recurso de apreensão das informações foi a entrevista semiestruturada, realizada com 12 trabalhadoras com idades entre 29 e 55 anos. RESULTADOS: As informações submetidas à análise temática apontaram que a assistência fisioterapêutica recebida repercute em períodos longos de tratamento e na insatisfação dos resultados, por meio de uma prática curativista, segmentada e pouco resolutiva, na qual prevalece a utilização de equipamentos em detrimento das manobras corporais e holísticas. CONCLUSÃO: Diante dos relatos, verificamos a necessidade de uma atenção humanizada, integral e equânime com responsabilização e vínculo, além da valorização dos trabalhadores e usuários, promovendo melhor qualidade de vida. É imprescindível a realização de novos estudos que possibilitem melhor compreensão e aprofundamento teórico e prático da relação entre a atuação do fisioterapeuta e as representações sociais envolvidas

Leishmania infection in a population of dogs: an epidemiological investigation relating to visceral leishmaniasis control

Identification of factors associated with Leishmania infection in dogs is essential for targeting visceral leishmaniasis control actions. Thus, the present study analyzed some of these factors in a population of dogs in a Brazilian municipality, along with the limitations of control strategies implemented there. The association between the exposure variables and occurrences of infection was analyzed through logistic regression models. The disease control interventions were treated qualitatively. Out of the 755 animals examined, 13.6% (103/755) were seropositive. Of these, 23.3% (24/103) were asymptomatic and 76.7% (79/103) presented at least one clinical sign possibly associated with visceral leishmaniasis. With weak associations, purebred, shorthaired, over 5 years of age, male and large dogs were more prone to infection. The latter two variables formed the final regression model and the association with dog size was statistically significant. The control strategies developed presented limitations and a great number of seronegative dogs was culled. The data presented contribute towards better understanding of the dynamics of infection in canine visceral leishmaniasis and indicate that actions aimed towards adequate implementation of Visceral Leishmaniasis control program in Brazilian endemic areas should be prioritized
