During the ninth century, owing to the process of industrialization, new social conflicts were showed, forcing the Government not to remain inert. The necessity of answer to these new demands requires from the State some actions that assure the new economic, cultural and social rights, able to exceed the formal equality, according to the principles of redistributive equality and well-being. Among the social rights, the right to health is showed up, which is placed at the Universal Declaration of Human Rights and the International Treaty for the Economic, Social and Cultural Rights, as a necessary term to promote the dignity and the free development of the human personality. Under the Constitutional Law, it is clear that the implementation of the right to health, placed at the 6th article of the Brazilian Constitution, demands a government activity, which usually requires a provision of material goods, depending on budgetary resources. The Legislative and Executive Branches have a very important role in compliance with the constitutional regulations about the satisfactory offer of health care services, besides the correct use of the resources at this area. The adoption of public policies is the way of Government action to the planning and realization of this right. Though, some public policies are usually made apart from the social compromises, to the detriment of the basic social rights. The government has a discretionary competence to manage the health services. That is the reason it is necessary the control of the political choices, through the popular control, the extrajudicial control by the Account Courts, or the judicial review. Owed to the constitutionalization of social rights, the constitutional justice has a very relevant role, concerning to the constitutional jurisdiction, in a way the Judiciary Branch assume your position as a player that transforms the society. On the control of the public health policies, there is a cast of official instruments, judicial or not, to the guarantee of the collective right to the public health services, and to allow the citizens to reach the real implementation of the right to health

O objetivo desta pesquisa é propor um modelo numérico prognóstico que trate a variável “tempo” de forma eficiente e eficaz, com a finalidade de atender às reais necessidades dos clientes-usuários e à sociedade em geral. Todavia, realizou-se um levantamento bibliográfico sobre gestão pública, no tocante a obras públicas, estatística e pesquisa operacional para sistema organizacional, visando à modelagem numérica. A pesquisa foi baseada em metodologias quantitativas, com ênfase na pesquisa operacional para o estudo das obras públicas executadas sob a gerência da Prefeitura (PCU) da Universidade Federal do Pará (UFPA). Para a elaboração da base de dados, foram coletados informações de obras, reformas e ampliações, executadas durante o período de 2006 a 2009, junto à Comissão Permanente de Licitação (CPL) e à Fundação de Amparo ao Desenvolvimento da Pesquisa (FADESP). Mediante as regressões lineares e, após as transformadas das funções, foram obtidos para o modelo prognóstico os parâmetros estatísticos: coeficiente de correlação (R), de 0,899; coeficiente de determinação (R²), de 0,808; coeficiente de determinação ajustado (R² ajustado), de 0,796; e erro padrão (Se), de 0,41. Esses parâmetros demonstram forte correlação linearizada entre as variáveis, indicando que 79,60% da variabilidade do tempo para executar uma obra pública é causada ou produzida pela variação, em conjunto, da área; do valor orçado; da capacidade técnica operacional da IFES; da capacidade operacional da empresa; da tipologia de serviço; e da estação do ano. Com os resultados obtidos, conclui-se que é possível aplicar e implementar o modelo prognóstico para execução de obras públicas, pois se obteve uma ferramenta potente em sua aplicação para as melhorias dos procedimentos administrativos, tanto na estrutura como no seu desempenho, cujo principal resultado é a previsão do tempo para execução do empreendimento público.

Background and Objective Muscle regeneration is a complex phenomenon, involving coordinated activation of several cellular responses. During this process, oxidative stress and consequent tissue damage occur with a severity that may depend on the intensity and duration of the inflammatory response. Among the therapeutic approaches to attenuate inflammation and increase tissue repair, low-level laser therapy (LLLT) may be a safe and effective clinical procedure. The aim of this study was to evaluate the effects of LLLT on oxidative/nitrative stress and inflammatory mediators produced during a cryolesion of the tibialis anterior (TA) muscle in rats. Material and Methods Sixty Wistar rats were randomly divided into three groups (n?=?20): control (BC), injured TA muscle without LLLT (IC), injured TA muscle submitted to LLLT (IRI). The injured region was irradiated daily for 4 consecutive days, starting immediately after the lesion using a AlGaAs laser (continuous wave, 808?nm, tip area of 0.00785?cm2, power 30?mW, application time 47?seconds, fluence 180?J/cm2; 3.8?mW/cm2; and total energy 1.4?J). The animals were sacrificed on the fourth day after injury. Results LLLT reduced oxidative and nitrative stress in injured muscle, decreased lipid peroxidation, nitrotyrosine formation and NO production, probably due to reduction in iNOS protein expression. Moreover, LLLT increased SOD gene expression, and decreased the inflammatory response as measured by gene expression of NF-k beta and COX-2 and by TNF-a and IL-1 beta concentration. Conclusion These results suggest that LLLT could be an effective therapeutic approach to modulate oxidative and nitrative stress and to reduce inflammation in injured muscle. Lasers Surg.
