    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

    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

    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 TaubatĂ© Basin region, a highly urbanized portion of southeastern SĂŁo 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

    O lugar ocupado pela assistĂȘncia fisioterapĂȘutica: representaçÔes sociais de trabalhadores com DORT

    Get PDF
    INTRODUÇÃO: Os distĂșrbios osteomusculares relacionados ao trabalho (DORT) articulam-se diretamente Ă  realização de atividades ocupacionais e Ă s condiçÔes de trabalho. OBJETIVO: O artigo origina-se de uma pesquisa qualitativa que analisou as representaçÔes sociais da assistĂȘncia fisioterapĂȘutica entre trabalhadores portadores de DistĂșrbios Osteomusculares Relacionados ao Trabalho (DORT), frequentadores do Centro de ReferĂȘncia em SaĂșde do Trabalhador (CEREST), pelo Departamento de SaĂșde do Trabalhador (DSAT), Juiz de Fora (MG). MATERIAIS E MÉTODOS: O recurso de apreensĂŁo das informaçÔes foi a entrevista semiestruturada, realizada com 12 trabalhadoras com idades entre 29 e 55 anos. RESULTADOS: As informaçÔes submetidas Ă  anĂĄlise temĂĄtica apontaram que a assistĂȘncia fisioterapĂȘutica recebida repercute em perĂ­odos longos de tratamento e na insatisfação dos resultados, por meio de uma prĂĄtica curativista, segmentada e pouco resolutiva, na qual prevalece a utilização de equipamentos em detrimento das manobras corporais e holĂ­sticas. CONCLUSÃO: Diante dos relatos, verificamos a necessidade de uma atenção humanizada, integral e equĂąnime com responsabilização e vĂ­nculo, alĂ©m da valorização dos trabalhadores e usuĂĄrios, promovendo melhor qualidade de vida. É imprescindĂ­vel a realização de novos estudos que possibilitem melhor compreensĂŁo e aprofundamento teĂłrico e prĂĄtico da relação entre a atuação do fisioterapeuta e as representaçÔes sociais envolvidas

    Scientific Opinion addressing the state of the science on risk assessment of plant protection products for in-soil organisms

    Get PDF
    Following a request from EFSA, the Panel on Plant Protection Products and their Residues developed an opinion on the science behind the risk assessment of plant protection products for in-soil organisms. The current risk assessment scheme is reviewed, taking into account new regulatory frameworks and scientific developments. Proposals are made for specific protection goals for in-soil organisms being key drivers for relevant ecosystem services in agricultural landscapes such as nutrient cycling, soil structure, pest control and biodiversity. Considering the time-scales and biological processes related to the dispersal of the majority of in-soil organisms compared to terrestrial non-target arthropods living above soil, the Panel proposes that in-soil environmental risk assessments are made at in- and off-field scale considering field boundary levels. A new testing strategy which takes into account the relevant exposure routes for in-soil organisms and the potential direct and indirect effects is proposed. In order to address species recovery and long-term impacts of PPPs, the use of population models is also proposed
