Studies have shown that autistic adults and adolescents have a high incidence of cavities due to their substandard practices of oral hygiene. Disruptive behaviors like flinching or fleeing are commonly observed during toothbrushing, as well as agonistic conduct during dental treatment. Few studies have addressed the improvement of toothbrushing efficacy as a form of preventing these problems, and most of the existing works are poor in methodology. This study evaluates the effectiveness of a toothbrushing training program upon children of five to six years of age who have been medically diagnosed as autistic. The children were randomly divided into groups G1, G2 and G3. G1 had training on the use of conventional toothbrushes, with an accompanying song and physical guidance; G2 had electric toothbrush training and physical assistance; group G3 had electric toothbrush training, associated to a song and physical assistance. Video recordings of the training sessions were used to determine the brushing steps assimilated by the children, as well as their autonomy and ability to complete each of the steps along the study. Hygiene results were evaluated through a sequence of treatments and probes. The use of electric toothbrushes apparently resulted in better removal of plaque, even under adverse conditions. G3 showed better plaque indexes than the other two groups, and G2 had better results than G1, suggesting that the use of electric toothbrushes associated to a song and physical assistance can optimize oral hygiene in autistic children. Overall, five-year-olds had better results than sixyear- olds, suggesting that younger children have a lower incidence of adverse behavior (e.g. nausea or vomiting) during toothbrushing.

The purpose of this work is to examine statistical methodologies that can be applied to problems that involve a large number of variables using as a tool graphical models that assist on the visualization of the conditional independency and dependency structure, thus a graphical model represents the relationship between random variables (dependence, independence and conditional independence), each node is a random variable and the edges between the nodes are different ways they relate to each other. This dissertation studies Gaussian graphical models. We use methodologies for large scale models (\large p and small n") used on the analysis of gene association from gene expression data. We describe the sparse graphical models and we implement a computational algorithm. We veriffed a Bayesian approach using the Reversible Jump MCMC. We also introduce decomposable graphical models in relation to the computational effciency attained by the decomposition of the sample space, and we found the best decomposable graph based on the Metropolis-Hastings algorithm for a real data set.

The inability to oxidize fat is a key factor in the etiology of obesity. However, improved performance and VO2max resulting from physical training leads to increased rates of oxidation of fats. Although, there is still a lack of information about the intensity of exercise can interfere with metabolism of carbohydrates and lipids in obese women during a session of exercise and its recovery, because only in an experimental study there is a negative relationship of obesity on the reinstatement of power after a year. Therefore, this study aims to assess the behavior of the metabolism of carbohydrates and lipids in moderately obese women on a test of acute exercise effects on the intensity of ventilatory threshold and the recovery period, in the stage of pre-and post-training physical. This study had the participation of seven women slightly obese (BMI=4.03 kg/m2), with an average age of 43.0 ± 4.0 years, 163 ± 0.2±33.59 cm and previously sedentary who were submitted to the ergospirometry acute test before and after 16 weeks of training in the intensity of ventilatory threshold. During the test respiratory quotient was evaluated to determine the fats and carbohydrates oxidation during exercise and recovery period. The results found that the volunteers used predominantly the energy that comes from carbohydrates during the session of exercise (67.64% and 69.35% of the total spent provided pre-and post-training, respectively). During recovery the percentage of the fats contribution increase of (46.52% of the total oxidized) to the total energy generated, which discreetly marked with training (53.48% of the total oxidized). Based on the findings was observed that the metabolism of carbohydrates provides the muscle contraction support during the exercise in the intensity of ventilatory threshold and that the recovery period lipid metabolism is the counterpart to repay the body stores energy in obese women.
Educadores sociais e suas práticas junto a jovens: o cotidiano de ONGs na cidade de Campinas/SP
(Universidade Federal de São Carlos, 2008-06-27) Borba, Patrícia Leme de Oliveira; Lopes, Roseli Esquerdo; https://lattes.cnpq.br/1507752191797249; https://lattes.cnpq.br/4193205735379897
Simultaneously to the strengthening of the neoliberal political project in Brazil, it has been experimented a national outspreading of the Non-Governmental Organizations (NGOs), that accomplish the educational practices directed to the youngsters and particularly to the lacking youngster. The present research has intended to analyze the educative practice accomplished by the social educators in two NGOs in Campinas city - São Paulo State, which organizations that actuate in the field of education and social assistance, and dedicated to the social educative area along youngsters in situation of social vulnerability, what is done in a period complementary to the school period. For such, it has been used methods like participative observation, along respective logging in a period of two months in each institution. The interviews half-structured with work team and the youngsters, as well a game, entitled Consensus Game as a facilitator means of the youngsters thoughts, related to the their experiences in the organizations studied. The whole of these material were analyzed based in the major categories, which this work embrace the concepts and discussions about the role of the ONGs/ Third Sector in the contemporary Brazilian society; the present condition of the youth and youngster lacking and urban; the education in its sense more comprehensive, as interest us, in this path, either the ways of formal education and the non formal practices and the social educators theirselves. With empiric data arranged according a theorical support, has provided some discussion, among them, the image of the social educator(s); the consequences of the voluntary work and the low wages given to the professional educators, the programs of revenues transferring and the deepening of the category Respect as guide line for a new understanding of the practices of educator, from a youngsters point of view. In respect to the plurality of difficulties faced by the social educator in daily basis - a material shortage for their intervening, fragile back ground, low wages, technical work gotten as voluntary, among others, such practices can favors, restrictedly and individually, the enlarging of the social net of support of the caring youngsters, and else, operating in the assistancialism logic, since macro-socially does not yield changes in the population target, for instance, the lacking youngster. Thus, we realize that there are an alignment, conscient (or not) to the hegemonic neoliberal political project that reproduces the social, economic and political differences inherent to the production model of the capitalism, and contributing in maintaining the present status quo. Finally, the present research intend to contribute for a better qualification of the practices proposed in the spaces here analyzed, for revealing the objectives implicit in the present model of the public intervening in the social issue, as well to yield subsides for creating and implementing public politics facing young and youngster, putting them as rights carriers, specially to project their lives in a direction of autonomy and respect.

The focus on management practices - especially the ones that improve the fulfillment of the demands and needs of people involved with the organization - has grown due to the increase in competition, causing changes in the organizations conventional way of working. In the public sector, management has been modified and still is. Literature shows that the present model of Public Management does not fulfill completely the needs and growing demands of the citizens. As a consequence, it is possible to find some areas in which managerial practices have already been adopted. Therefore, this study analyses the viability of applying the strategy of management by processes in Public Management. This strategy has been applied to private companies with strong positive results. The empirical part of the study was developed at UFSCar (Federal University of São Carlos), aiming at identifying the present context and the main aspects (favorable or not) involved in introducing the strategy of management by processes in four selected processes.

In this work, structural and dynamic properties of a two-dimensional electron system trapped to helium film, deposited on a solid substrate, are determined through molecular dynamics simulation. The influence of the film thickness and type of substrate on those properties are analyzed in the numerical experiments. A special attention is given to dynamical structure factor that is used to obtain some important properties of this system, like dispersion and mobility of electrons. For the first time, the dynamic structure factor from interacting electron system is applied to the calculus of mobility, introducing a many body effect.
