Propriedades críticas do processo epidêmico difusivo com interação de Lévy

The diffusive epidemic process (PED) is a nonequilibrium stochastic model which, exhibits a phase trnasition to an absorbing state. In the model, healthy (A) and sick (B) individuals diffuse on a lattice with diffusion constants DA and DB, respectively. According to a Wilson renormalization calculation, the system presents a first-order phase transition, for the case DA > DB. Several researches performed simulation works for test this is conjecture, but it was not possible to observe this first-order phase transition. The explanation given was that we needed to perform simulation to higher dimensions. In this work had the motivation to investigate the critical behavior of a diffusive epidemic propagation with Lévy interaction(PEDL), in one-dimension. The Lévy distribution has the interaction of diffusion of all sizes taking the one-dimensional system for a higher-dimensional. We try to explain this is controversy that remains unresolved, for the case DA > DB. For this work, we use the Monte Carlo Method with resuscitation. This is method is to add a sick individual in the system when the order parameter (sick density) go to zero. We apply a finite size scalling for estimates the critical point and the exponent critical =, e z, for the case DA > DB

Reanimação neonatal: capacitação de profissionais de saúde com base na aprendizagem baseada em problemas

In whole world, including in Brazil, there is an absence of professionals who are able to be present at the moment of birth and give to the newborn the cares that they need to because either an absence of opportunity or inappropriate training to those professionals. This master´s thesis describes a construction and application of a neonatal resuscitation course that uses the problem based learning (PBL) methodology. The course has done in two meetings, one for the tutorial session, and another for practice session. The students were divided in groups of eight students each, under supervision of two teachers with experience in PBL methodology. The experience was considered successfully because there were students involvement and motivation. Some course aspects were rebuilt for its upgrading, like the correct use of methodology and building of custom educational material for students learning necessity. It suggests that the course can be used by the medical and nursing schools and perhaps other kind of health courses.
