O presente trabalho tem por objetivo avaliar a distribuição espacial, por geoestatística, da produção de água gerada pelo modelo hidrológico matemático SWAT 2009 (Soil and Water Assessment Tool, versão 2009), da parte inicial da bacia hidrográfica do Rio Pardo – SP. Foi utilizado um Sistema de Informação Geográfica (SIG) associado a uma interface com o modelo SWAT para a confecção do banco de dados. Para isto, as informações de entrada necessárias para avaliar a produção de lâmina de água (mm), que infiltrou e armazenou em cada sub-bacia gerada pelo SWAT, referem-se a dados tabulares climáticos e de parâmetros físicos e químicos de solo e a planos de informações como: o Modelo Numérico do Terreno (MNT), Mapa de Uso do Solo e Mapa de Solos. A amostragem geoestatística foi representada por uma malha irregular georreferenciada com 43 pontos localizados na parte central de cada sub-bacia representando a quantidade de água produzida. A análise geoestatística foi realizada pela construção dos variogramas e posteriormente a confecção dos mapas interpolados por krigagem. Do resultado obtido observou-se que a produção de água apresentou dependência espacial e que esta ocorreu de forma homogênea, tanto para os maiores como para os menores valores de produção de água encontrados na bacia.

In different regions of Brazil, population growth and economic development can degrade water quality, compromising watershed health and human supply. Because of its ability to combine spatial and temporal data in the same environment and to create water resources management (WRM) models, the Geographical Information System (GIS) is a powerful tool for managing water resources, preventing floods and estimating water supply. This paper discusses the integration between GIS and hydrological models and presents a case study relating to the upper section of the Paraíba do Sul Basin (Sao Paulo State portion), situated in the Southeast of Brazil. The case study presented in this paper has a database suitable for the basin's dimensions, including digitized topographic maps at a 50,000 scale. From an ArcGIS®/ArcHydro Framework Data Model, a geometric network was created to produce different raster products. This first grid derived from the digital elevation model grid (DEM) is the flow direction map followed by flow accumulation, stream and catchment maps. The next steps in this research are to include the different multipurpose reservoirs situated along the Paraíba do Sul River and to incorporate rainfall time series data in ArcHydro to build a hydrologic data model within a GIS environment in order to produce a comprehensive spatial-temporal model.

Understanding the linkages between the natural elements is essential for being promoted the land use, occupation and sustainable management of environmental systems. Universal Soil Loss Equation (USLE), as a predictive model of erosion, is important to allowing the prevention of possible environmental impacts which may drastically interfere in natural or anthropic environments, as well as prevent potential financial wastes and even contribute to greater efficiency of agricultural production. This research will be working some USLE parameters, emphasizing topographic factor from Ribeirão Monjolo Grande watershed. Among the factors considered by the USLE, the Topographic Factor interferes directly in the erosive dynamic of a watershed because it involves variables related to hydrological processes that occur on it. In this research, were discussed different methods for obtaining the Topographic Factor (BERTONI e LOMBARDI NETO, 1985; MOORE e BURCH, 1986; DESMET E GOVERS, 1996) in GIS environment. After comparison between the methods, was indicated that best represents the conditions of geometry strand of the study area. Finally, other factors (R, K, C, P) considered by the USLE were obtained. The attainment of these parameters were guided by the use of geotechnologies, especially in Geographic Information Systems (GIS), with the assistance of secondary data and periodic field visits. The results obtained contributed to the understanding of hydrosedimentological dynamic in this area and serve as a viable strategy for studies of soil loss, aiming at developing consistent material for future researches about environmental planning and land management

Air pollution is an environmental issue worldwide and frequently cause negative effects on population health and ecosystems on cities. The relationship between climate and atmospheric pollution can be used as a surrogate to the intensity of air pollution. The present and quantity of some gases can be used as indicators to air quality: particulate matter (PM), sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3), and nitrogen dioxide (NO2). Among those gases, CO has its major source within the cities, where automobiles are the main emitter. But measure pollutant concentration are challenging, sometimes because the lack of good equipments due to high costs and of the large variability of models that varies in precision, way of measure and distribution of sellers. Modeling are useful when there are an intend to evaluate air pollution, its sources and evaluate scenarios. This work aims to use CAL3QHCR model developed by the U.S Environmental Protection Agency (EPA) to generate predictive surfaces of CO concentration distribution on a site within Campinas city, located in São Paulo state, Brazil. CAL3QHCR model use data urban automobile circulation to generate spatial results for CO distribution. We observed that the pollution concentration was lower on our modeling than the concentrations measured by Companhia Ambiental do Estado de São Paulo (CETESB), the main environmental company on the São Paulo state. Also the correlation between average estimates of our model and the measure by CETESB was weak, indicating that the model used on this study need to be or better parameterized, or the scale we measured of CO emissions need to be rescaled. Although the model failed to correlate to CETESB data, maybe one that explore the estimated emissions distributed within the sites to understand spatial distributions of CO on the regions. Also, the generated information can also be used to other studies, and come to be useful to explain heat island

By the end of the 1970´s, begins the Psychiatric Reform Movement, whose development was the beginning of the construction of a new model, here termed Psychosocial Attention, to substitute the traditional psychiatric model. As such, aspires to be a process of paradigm shift and, therefore, requires transformations in the fields: theoretical-conceptual, technical-assistance, legal-political e sociocultural. This qualitative study composes a research which sought to ascertain the scientific production on the topic conducted by psychology, from the implementation of the Brazilian National Health System and the creation of new services to mental health care. In this sense, it proposed to investigate how the papers published in journals of psychology found in the database LILACS, since 1990, contribute to the process of building a new model that actually replace the so-called traditional psychiatric model.

Abstract A fuzzy linguistic model based on the Mamdani method with input variables, particulate matter, sulfur dioxide, temperature and wind obtained from CETESB with two membership functions each was built to predict the average hospitalization time due to cardiovascular diseases related to exposure to air pollutants in São José dos Campos in the State of São Paulo in 2009. The output variable is the average length of hospitalization obtained from DATASUS with six membership functions. The average time given by the model was compared to actual data using lags of 0 to 4 days. This model was built using the Matlab v. 7.5 fuzzy toolbox. Its accuracy was assessed with the ROC curve. Hospitalizations with a mean time of 7.9 days (SD = 4.9) were recorded in 1119 cases. The data provided revealed a significant correlation with the actual data according to the lags of 0 to 4 days. The pollutant that showed the greatest accuracy was sulfur dioxide. This model can be used as the basis of a specialized system to assist the city health authority in assessing the risk of hospitalizations due to air pollutants.

The British sports suffered an unprecedented crisis in the early 80s instabilities political, economic crisis and lack of planning put the English sport in a very critical situation. However, a number of sports public policies were proposed from the 80's, effectively, completely changed the situation of English sport, which has prompted the development of this research. Thus, the present study, qualitative, aims to analyze the organization and evolution of the sport in the UK, based on the British government projects of the last 30 years included in the Sport Development database. Therefore, the study was developed by the union of bibliographic research, exploratory and documentary. First, after literature, documents were selected, using the academic database Sport Development, in the library of policy documents, separate area of the database containing only the English sport policy documents. For delimitation of the study were analyzed documents from 1980 to 2013, of which eight were selected on which to base discussions in this study. The documents were analyzed using thematic content analysis technique, based on two thematic axes: Axis 1 - funding and Axis 2 - priority groups. The results indicate that the analyzed initiatives show a process of evolution and maturation of public policies of Sport England, both on the issue of financing, such as with regard to priority groups, which have changed and adjustments over the years. It was also noted that much can be learned from these initiatives, even in helping to solve problems of the Brazilian reality. Suggest new studies involving sports management from different countries, in order to leverage other perspectives to support the development of public policies for sport and recreation in the country, seeking successful examples
