Urban stormwater can be considered as potential water resources as well as problems for the proper functioning of the manifold activities of the city, resulting from inappropriate use and occupation of the soil, usually due to poor planning of the occupation of the development areas, with little care for the environmental aspects of the drainage of surface runoff. As a basic premise, we must seek mechanisms to preserve the natural flow in all stages of development of an urban area, preserving the soil infiltration capacity in the scale of the urban area, comprising the mechanisms of natural drainage, and noting preserving natural areas of dynamic water courses, both in the main channel and in the secondary. They are challenges for a sustainable urban development in a harmonious coexistence of modern developmental, which are consistent with the authoritative economic environmental and social quality. Integrated studies involving the quantity and quality of rainwater are absolutely necessary to achieve understanding and obtaining appropriate technologies, involving both aspects of the drainage problems and aspects of use of water when subjected to an adequate management of surface runoff , for example, the accumulation of these reservoirs in detention with the possibility of use for other purposes. The purpose of this study aims to develop a computer model, adjusted to prevailing conditions of an experimental urban watershed in order to enable the implementation of management practices for water resources, hydrological simulations of quantity and, in a preliminary way, the quality of stormwater that flow to a pond located at the downstream end of the basin. To this end, we used in parallel with the distributed model SWMM data raised the basin with the highest possible resolution to allow the simulation of diffuse loads, heterogeneous characteristics of the basin both in terms of hydrological and hydraulic parameters on the use and occupation soil. The parallel work should improve the degree of understanding of the phenomena simulated in the basin as well as the activity of the calibration models, and this is supported by monitoring data acquired during the duration of the project MAPLU (Urban Stormwater Management) belonging to the network PROSAB (Research Program in Basic Sanitation) in the years 2006 to 2008

A partir da análise da Política Nacional de Saúde Mental formulada nos últimos anos e das experiências desenvolvidas após 1987 no país, procura-se compreender como o Sistema Único de Saúde tem contribuído ao avanço da reforma psiquiátrica nos municípios; verificar como a assistência oferecida nesses municípios está viabilizando os princípios da reforma psiquiátrica e a melhora das condições de vida dos usuários, bem como pesquisar o papel dos trabalhadores e gestores na construção de novas práticas de cuidado em Saúde Mental. A análise das práticas discursivas aponta que os vários segmentos sociais envolvidos na Saúde Mental conhecem os princípios e propostas da reforma psiquiátrica. No entanto, as gestões municipais não assumem integralmente as propostas do Ministério da Saúde para a área, sob a alegação de falta de recursos financeiros para a contrapartida exigida. Os usuários e familiares têm aos poucos assumido as novas propostas de intervenção, mas os mecanismos de participação e organização popular ainda são incipientes. Por fim, deve-se destacar que, para uma efetiva consolidação das propostas atuais da reforma psiquiátrica, é necessário um maior compromisso dos gestores com a atenção em Saúde Mental, maior investimento nas equipes multiprofissionais, o estímulo à organização e à participação dos usuários e familiares e a integralidade dos dispositivos de saúde, de assistência social e de cultura existentes nas cidades.

Mental Health, in the form of the Psychiatric Reform, and the Anti-Asylum Movement do not ignore the production of knowledge about that field, mainly due to the consolidation of Public Health as a field of knowledge. The article explores some authors who consider Mental Health as a new field of knowledge, introducing a new paradigm in the perception of health - Disease and Care -; however, the goal is to introduce Psychosocial Care as a means to enforce the transdisciplinary and multiprofessional practices. The possibility is that mental health produces developments in Health, consolidating the public policies. In practice, the hospital-centered and drug-based model still predominates, and there are setbacks to be overcome by taking advantage of loopholes capable of breaking with what is instituted.

This research presents a methodology for prediction of building shadows cast on urban roads existing on high-resolution aerial imagery. Shadow elements can be used in the modeling of contextual information, whose use has become more and more common in image analysis complex processes. The proposed methodology consists in three sequential steps. First, the building roof contours are manually extracted from an intensity image generated by the transformation of a digital elevation model (DEM) obtained from airborne laser scanning data. In similarly, the roadside contours are extracted, now from the radiometric information of the laser scanning data. Second, the roof contour polygons are projected onto the adjacent roads by using the parallel projection straight lines, whose directions are computed from the solar ephemeris, which depends on the aerial image acquisition time. Finally, parts of shadow polygons that are free from building perspective obstructions are determined, given rise to new shadow polygons. The results obtained in the experimental evaluation of the methodology showed that the method works properly, since it allowed the prediction of shadow in high-resolution imagery with high accuracy and reliability.

As cidades são textos. Textos escritos pelas sociedades que compõe os espaços. A partir dessa perspectiva, propõe-se aqui uma leitura do bairro da Ribeira Natal/RN. Esse espaço se consolidou no início do século XX como centro comercial e cultural da capital potiguar, lugar de ação e de interação da Zona Central desta sociedade, espaço de inscrição dos signos da modernidade e do progresso então em voga. Contudo, com o decurso do tempo e as transformações por ele exigidas, o panorama da Cidade de Natal sofreu intensas modificações e o bairro da Ribeira foi relegado à margem desse processo, o que culminou na desvalorização, segregação e, posteriormente, na degradação do seu espaço, que se tornou um palimpsesto. Ao abordar a dinâmica urbana que se processou no bairro da Ribeira, esta pesquisa dividiu o fenômeno em três fases distintas: valorização, transição e decadência
