Planejamento de atividades anti-tuberculose pelo método CENDES/OPS

O método CENDES/OPS foi aplicado no município de Araraquara (S. Paulo). O dano tuberculose foi programado de acordo com o modelo normativo. Foram elaborados outros programas com dados simulados, com o objetivo de se verificar a influência de variações na proporção de vacináveis, incidência da doença e eficácia da vacina BCG. As atividades anti-tuberculose foram programadas segundo as características epidemiológicas da área programática. A discrepância entre os resultados foi muito grande, salientando-se que as previsões orçamentárias efetuadas de acordo com o modelo normativo foram oito vezes superiores ao orçamento elaborado com os dados epidemiológicos da área.

Food Co-ops Toolkit

More and more communities are setting up food co-ops so they can get good food atan affordable price and have more control over where their food comes from. Co-operation is all about two or more people joining forces and working together to achieve something they probably couldn't do on their own. In the case of food co-ops a group of people join forces in order to be able to buy foodsthey may otherwise find it hard to get hold of at aprice they can afford.By volunteering their time and pooling their buying power they cangetproducedirect from local farmers or wholesalers. This toolkit was produced as part of the Big Lottery fundedMaking Local Food Work programmeto help morecommunitiesset up their own food co-ops and buying groups.The Food Co-ops project has now ended but the toolkit and other resources will all remain on-line.To find moreabout food co-opsyou can visit our main website www.foodcoops.org

Estimation of the probability of congestion using Monte Carlo method in OPS networks

In networks with small buffers, such as optical packet switching based networks, the convolution approach is presented as one of the most accurate method used for the connection admission control. Admission control and resource management have been addressed in other works oriented to bursty traffic and ATM. This paper focuses on heterogeneous traffic in OPS based networks. Using heterogeneous traffic and bufferless networks the enhanced convolution approach is a good solution. However, both methods (CA and ECA) present a high computational cost for high number of connections. Two new mechanisms (UMCA and ISCA) based on Monte Carlo method are proposed to overcome this drawback. Simulation results show that our proposals achieve lower computational cost compared to enhanced convolution approach with an small stochastic error in the probability estimation

Os efeitos da auditoria independente (externa) sobre a manipulação da informação contábil por parte das OPS brasileiras

A presente pesquisa busca investigar se a auditoria externa (independente) minimiza a propensão à manipulação das informações contábeis - MIC (medidas pelas acumulações discricionárias correntes) por parte das operadoras de plano privado de assistência à saúde, no que tange às informações econômico-financeiras divulgadas à Agência Nacional de Saúde Suplementar. Após revisão bibliográfica sobre qualidade da informação contábil, auditoria e mercado de saúde suplementar, promoveu-se uma pesquisa empírica com informações prestadas à ANS pelas OPS relativas ao período de 2004 a 2006. Para verificar se há diferença significativa no nível de acumulações discricionárias correntes, medidas pelo modelo AWCA e Jones Modificado (1995), entre as informações auditadas (quarto trimestre de cada ano) e as informações nãoauditadas (três primeiros trimestres de cada ano) para as mesmas empresas foi aplicado o teste não-paramétrico de Mann-Whitney. Os resultados indicam que não existem diferenças estatísticas significativas na propensão à manipulação entre as informações contábeis auditadas e não-auditadas, pelo menos no que tange às informações de 2004 a 2006 prestadas pelas OPS à ANS. Adicionalmente, também foram testadas as influências do tipo de modalidade, porte da firma e situação apresentada do patrimônio líquido sobre as acumulações discricionárias correntes. Observou-se que essas três variáveis influenciam em maior ou menor grau na manipulação da informação contábil gerada pelas OPS à ANS. Neste contexto, as seguintes características sobre a maior propensão a MIC foram diagnosticadas: Cooperativa Odontológica e a Medicina de Grupo (Modalidade); Pequeno (Porte da Firma); e Passivo a Descoberto ou PL Próximo de Zero (Situação do Patrimônio Líquido). Ao passo que as características relacionadas à menor propensão de MIC foram: Cooperativa Médica e Filantropia (Modalidade); Médio e Grande (Porte da Firma); Patrimônio Líquido Favorável (Situação do Patrimônio Líquido).

Viability of OPS Vitrified Sheep Embryos After Direct Transfer

The aim of this study was to evaluate the viability in the effect of open pulled straw (OPS) vitrification procedure of sheep embryos after direct transference. Embryos were produced in vivo and cryopreserved in slow freezing or OPS vitrification. The survival rates of cryopreserved embryos were compared to non-frozen standard pattern. In a first set of experiments, embryos at morula and blastocyst stages were dived in ethylene glycol (1.5 M) and frozen in an automatic freezer. After being thawed, they were directly or indirectly transferred to ewes recipient. A second group of embryos were drawn into OPS and plunged into liquid nitrogen after being exposed at room temperature for 1 min and 45 s in 10% EG plus 10% dimethyl sulphoxide (DMSO), then again for 30 s in 20% EG + 20% DMSO + 0.5 M sucrose. After being warmed, embryos were also directly transferred using a French mini straw as the catheter for the transplantation process or after in vitro dilution of cryoprotectants (two-step-process). No significant difference was observed among fresh, frozen or vitrified embryos on pregnancy rate (50.0%, 38.6% and 55.8%). However, when we evaluated only the direct transference, the pregnancy rate of OPS vitrified embryos was higher than that of frozen embryos (57.1% vs 34.8%) (p = 0.07). In addition, vitrified morulae had a higher pregnancy rate than the one with frozen embryos (64.0% vs 38.9%) (p = 0.07). Finally, our results indicate that OPS vitrification technique in association with direct transference improves the viability of sheep embryos with potential applications to field conditions.
