In soil surveys, several sampling systems can be used to define the most representative sites for sample collection and description of soil profiles. In recent years, the conditioned Latin hypercube sampling system has gained prominence for soil surveys. In Brazil, most of the soil maps are at small scales and in paper format, which hinders their refinement. The objectives of this work include: (i) to compare two sampling systems by conditioned Latin hypercube to map soil classes and soil properties; (II) to retrieve information from a detailed scale soil map of a pilot watershed for its refinement, comparing two data mining tools, and validation of the new soil map; and (III) to create and validate a soil map of a much larger and similar area from the extrapolation of information extracted from the existing soil map. Two sampling systems were created by conditioned Latin hypercube and by the cost-constrained conditioned Latin hypercube. At each prospection place, soil classification and measurement of the A horizon thickness were performed. Maps were generated and validated for each sampling system, comparing the efficiency of these methods. The conditioned Latin hypercube captured greater variability of soils and properties than the cost-constrained conditioned Latin hypercube, despite the former provided greater difficulty in field work. The conditioned Latin hypercube can capture greater soil variability and the cost-constrained conditioned Latin hypercube presents great potential for use in soil surveys, especially in areas of difficult access. From an existing detailed scale soil map of a pilot watershed, topographical information for each soil class was extracted from a Digital Elevation Model and its derivatives, by two data mining tools. Maps were generated using each tool. The more accurate of these tools was used for extrapolation of soil information for a much larger and similar area and the generated map was validated. It was possible to retrieve the existing soil map information and apply it on a larger area containing similar soil forming factors, at much low financial cost. The KnowledgeMiner tool for data mining, and ArcSIE, used to create the soil map, presented better results and enabled the use of existing soil map to extract soil information and its application in similar larger areas at reduced costs, which is especially important in development countries with limited financial resources for such activities, such as Brazil.

O presente trabalho tem o objetivo de criar uma metodologia para o Gerenciamento Integrado dos Resíduos Sólidos (GIRS) que associa a prática pertinente ao tema, com programas que envolvam a comunidade, no sentido de manter o meio ambiente limpo e saudável, tendo como cenário o município de Belém, especificamente a Bacia Hidrográfica da Estrada Nova (BHEN). Objetiva também identificar porquê, apesar da BHEN possuir coleta de resíduos e serviços de limpeza realizada pela Secretaria Municipal de Saneamento (SESAN), a mesma permanece, constantemente, suja, principalmente, de lixo e entulho lançados nas vias públicas e canais de drenagem dessa bacia. A pesquisa de campo consistiu de entrevistas com os principais atores desse trabalho, a comunidade da BHEN. Inova no município um modelo de programas de participação da população com o nome de Cidadania e Participação Ativa da Comunidade (CIPAC) propondo 20 programas: Mascote da educação ambiental; Boteco em boteco; Eu amo minha cidade; Alô comunidade; TV SOS “Meio ambiente”; Rádio “Desperta comunidade; Coral e teatro “Reciclar”; Educa móvel; Coleta seletiva nas escolas; O meio ambiente pede carona; Centro de memória; A escola do lixo; Conhecer o lixo; Comunidade nota 10; Futuro verde; Coleta seletiva “porta a porta” Implantação dos LEVs; Criação das unidades básicas ecológicas; Criação da central de reciclagem de entulho; Criação das unidades de triagem de materiais recicláveis; Criação das cooperativas de catadores e carroceiros. Faz uma previsão de investimentos para implantação e manutenção desses programas assim como o retorno do investimento aplicado com a implantação. Como resultado, apresenta um novo modelo, baseado na prática, como sustentação para o estabelecimento de uma política municipal, de acordo com a Lei da Política Nacional de Resíduos Sólidos (PNRS) que tramita no Congresso Nacional. Também foram identificados parâmetros capazes de identificar a inadequação do processo atual de coleta de lixo e dos serviços de limpeza nessa bacia. Esses resultados alcançados permitem concluir que grande parte da população da BHEN não está preparada para aderir a um programa de Gestão de Resíduos Sólidos (GRS), que tenha como ponto de partida o GIRS. O grau de escolaridade e o nível de conhecimento da comunidade não representam obstáculos para isso, mas sim a falta de programas que envolvam a sua participação, a coleta de resíduos e serviços de limpeza urbana corretamente prestados, pois, atualmente, na pesquisa de campo realizada, foram visivelmente reprovados. Finalmente, ainda conclui que somente com a implantação de um GIRS, com apoio do CIPAC o meio ambiente seria consideravelmente beneficiado, mas não resolveria os graves problemas ambientais da BHEN, será necessária a melhoria de todos os sistemas de infra-estrutura urbana nessa importante bacia, para um efeito realmente mais saudável. É importante destacar que, no momento atual, as propostas apresentadas por este trabalho são consideradas bastante oportunas, pois com o inicio da implantação do Programa de Recuperação Urbano-Ambiental da Bacia da Estrada Nova (PROMABEM) pela Administração Municipal financiado pelo Banco Interamericano de Desenvolvimento (BID), os problemas sanitários e ambientais dessa importante bacia têm grande probabilidade de ser resolvidos.

Este estudo trata da perspectiva de criação do Estado do Carajás sob o ponto de vista das representações parlamentares dos municípios das regiões sul e sudeste do Pará. As teorias sobre representação política e as críticas da teoria das elites nortearam a análise, visto que a temática da redivisão do território paraense tem inflamado os discursos de candidatos a cargos políticos, e durante a campanha do plebiscito de dezembro de 2011 o debate reverteu-se em animosidade entre as frentes pluripartidárias do sim e do não, pela alegação da frente oponente à emancipação, que a divisão tratava-se de um projeto político das elites locais. De base empírica, o levantamento de campo foi aplicado a vereadores dos 39 municípios da região. A pesquisa revelou que a mobilização política regionalista ancora-se na distância do poder decisório que deixaria a região fora da agenda governamental e enfatiza o esquecimento do poder público estadual. Os vereadores veem o novo estado como uma possibilidade de atender às demandas por políticas públicas e oportunidades de emprego e renda, mas percebem claramente uma oportunidade de crescimento de suas carreiras políticas e de aumentar a paridade na balança da representatividade do norte no Congresso Nacional.

The article describes political and legal aspects of Brazilian education, through the analysis of Brazilian Constitutions, its amendments and major educational laws and resolutions in force until 2012, highlighting those that make direct reference to rural education and country education. It intends to identify the time when the educational legislation has incorporated the term “country education”, one of the struggles of the Movement for a Country Education. The use of the term “country education” will occur only in the first decade of this century. Despite the difficulties in consolidating country education, clearly the incorporation of this issue in the draft of the new National Education Plan (2011/2020), under discussion in Brazilian Congress.

The objective of this work is to compare how manifests the ideological positioning in the hegemonic media productions, according to Gramsci's conception, in relation to the radical alternative media, proposed by John Downing. The research has as opinionated content sample printed newspaper O Estado de s. Paulo, contrasting with the expressions of NON-PROFIT bauruense environmental “Instituto Ambiental Vidágua on the proposals of the new Brazilian forest Code. The analysis will hold in an interval between the adoption of the code by the Chamber of deputies in April 2012, and the provisional measure of President Dilma Rousseff with 32 modifications, after vetoing 12 articles proposed initially in may 2012. To support the study, will be crafted Gramsci hegemony; What is the alternative and radical media as it manifests itself; the relationship between the environmental journalism with the environmental NGOs; opinionated journalism and journalistic genres opinionated; theories of journalism and framing of matter

The aim of this paper is to analyze the current brazilian high school situation that refers specifically to issues of infrastructure, training of professionals working in high school and the question of management of high school, because we believe that such questions also may have fundamental importance for both young people who drop out of high school and for young people who stay there. We will discuss these issues (infrastructure, management and training of professionals working in high school) as a reference, on the one hand, the goals and objectives proposed by the last National Education Plan (PNE - Law No. 10.172/2001), and on the other hand, the objectives and goals proposed for these same issues by the new PNE, to run until 2020, emphasizing that this is still under discussion in Congress, therefore, liable to modifications.

The media received from Brazilian Constitution an extensive regulatory role, however, despite the constitutional requirement, until these days, over twenty years after its promulgation, the Brazilian Congress hasn’t regulated all constitutional rules for the sector. In addition, some rules related to the media that were produced before and after the Constitution were expurgated by Brazilian Supreme Court decisions. This text is part of ongoing research that aims to present the constitutional regulation of the media and the development/implementation of these legal standards through decisions of the Supreme Court.

Objective: To determine the prevalence of patients with type 1 diabetes mellitus who meet the glycemic and cardiovascular (CV) risk factors goals and the frequency of screening for diabetic complications in Brazil according to the American Diabetes Association guidelines. Research design and methods: This was a cross-sectional, multicenter study conducted between December 2008 and December 2010 in 28 public clinics in 20 Brazilian cities. Data were obtained from 1774 adult patients (56.8% females, 57.2% Caucasians) aged 30.3 +/- 9.8 years with diabetes duration of 14.3 +/- 8.8 years. Results: Systolic blood pressure was at goal in 40.3% and diastolic blood pressure was at goal in 26.6% of hypertensive patients. LDL cholesterol and HbA1c were at the goal in 45.2% and 13.2% of the patients, respectively. Overweight was presented in 25.6% and obesity in 6.9%. Among those with more than 5 years of disease, screening for retinopathy was performed in the preceding year in 70.1%. Nephropathy and feet complications were screened in 63.1% and 65.1%, respectively. Conclusions: The majority of patients did not meet metabolic control goals and a substantial proportion was not screened for diabetic complications. These issues may increase the risk of chronic complications and negatively impact public health. (C) 2012 Elsevier Ireland Ltd. All rights reserved.

Polymeric nanoparticles (PLGA) have been developed for the encapsulation and controlled release of quercetin and catechin. Nanoparticles were fabricated using a solvent displacementmethod. Physicochemical properties were measured by light scattering, scanning electron microscopy and zeta-potential, X-ray diffraction, infrared spectroscopy and differential scanning calorimetry. Encapsulation efficiency and in vitro release profiles were obtained from differential pulse voltammetry experiments. Antioxidant properties of free and encapsulated flavonoids were determined by TBARS, fluorescence spectroscopy and standard chelating activity methods. Relatively small (d approximate to 400 nm) polymeric nanoparticles were obtained containing quercetin or catechin in a non-crystalline form (EE approximate to 79%) and the main interactions between the polymer and each flavonoid were found to consist of hydrogen bonds. In vitro release profiles were pH-dependant, the more acidic pH, the faster release of each flavonoid from the polymeric nanoparticles. The inhibition of the action of free radicals and chelating properties, were also enhanced when quercetin and catechin were encapsulated within PLGA nanoparticles. The information obtained from this study will facilitate the design and fabrication of polymeric nanoparticles as possible oral delivery systems for encapsulation, protection and controlled release of flavonoids aimed to prevent oxidative stress in human body or food products.
