This study involved observational assessment of work posture in relation to recommended ergonomic posture the requirements necessary for ergonomic posture among students in the final year of a degree program at the School of Dentistry of Araraquara-UNESP/Brazil (n =73) and investigation of the association of work posture with sex, the type of procedure, four-handed dentistry, and the region of the mouth being treated. The work posture of the students during 250 clinical procedures was observed by means of pictures. Each procedure received a posture classification: Adequate, partially adequate, or inadequate. A descriptive statistical analysis was conducted. The prevalence of final posture classification was calculated using 95% confidence intervals and point estimate. Associations of interest were studied using the chi-square test, with a 5% significance level. It was concluded that the prevalence of procedures performed with partially adequate posture was high, and that the final work posture classification was not associated with the variables of interest. © 2013 Taylor & Francis Group.

A suit able decision-making on managing a contaminated site characterization program is strongly dependent of the diagnosis process. A detailed diagnosis can be done based on a Conceptual Site Model (CSM) elaboration using high resolution site characterization tools. The piezocone (CPTu) test is a high resolution tool which allows attaching several specific sensors, like the resistivity probe. This hybrid device is called the resistivity piezocone (RCPTu). A simulated geo-environmental site characterization program was performed on an erosion site using different tools (direct push tools soil samplers, hollow stem auger (HSA) drilling and RCPTu tests) to develop the CSM for a site similar to the Brazilian conditions. It was observed a good agreement between the site profiles interpreted by the different methods. The resistivity sensor attached to the piezocone improved the interpretation and the decision-making process on site was significantly better for the CSM elaboration. The RCPTu test data also allowed identifying the hydrogeological heterogeneities. The present study shows that the RCPTu test is also a useful and powerful tool to development an accurate CSM in a Brazilian condition, especially in an approach that prioritizes high resolution geo-environmental investigation. © 2013 Taylor & Francis Group.

Projeto Calha Norte: política de defesa nacional e segurança hemisférica na governança contemporânea
Resumo:
Evidencia a análise do percurso institucional e geoestratégico do Projeto Calha Norte (PCN) como processo de territorialização da fronteira política. O PCN foi pensado nos moldes convencionais da defesa e influenciado pela Doutrina de Segurança Nacional (DSN) dos anos sessenta e setenta, que objetivava e objetiva garantir o aumento da presença do Estado na Faixa de Fronteira Norte (Arco Norte), contribuindo para a Defesa Nacional e para a assistência às populações locais. Busca entender as implicações históricas, estratégicas, geopolíticas, financeiras e ambientais, desde a sua origem até os anos noventa com ênfase no governo de Fernando H. Cardoso - FHC (1994-2002). Apresenta a idéia de que a política de defesa implementada por este obedeceu às inflexões das mudanças internas na governança brasileira, bem como almejou adequá-la às transformações em curso regional e mundialmente, caracterizadas pela substituição da ordem bipolar para multipolar/unipolar, alteração no perfil das instituições políticas e, sobretudo, da integração hemisférica do país num quadro de incertezas e apelo ao fortalecimento da segurança coletiva. Essas mudanças ocorreram no contexto da modernização capitalista, na qual o PCN é concebido como uma modalidade particular de intervenção e expansão do Estado, que tem o uso exclusivo do monopólio da força, cumprindo suas prerrogativas constitucionais numa área marrom - ausência do Estado enquanto um conjunto de burocracias funcionando efetivamente numa área de baixa densidade demográfica. A ineficácia dessas dimensões do Estado define a peculiaridade do circuito da ilegalidade, isto é, o locus das atividades ilícitas tais como o narcotráfico e o contrabando. Assim, a racionalidade presente na ação do Estado consiste em articular os elementos capazes de estimular a materialização de um processo de homogeneização do espaço social na fronteira política em contexto de integração e cooperação com os países da Pan-Amazônia. Baseando-se em indicadores demográficos, econômico-financeiros e ambientais, e numa ampla base de dados sobre a Faixa de Fronteira Norte, a pesquisa concluiu pela necessidade da intervenção na fronteira política, onde o Estado busca cumprir, relativamente, sua função para ordenar e disciplinar as relações e os processos sociais a partir de referências constitucionais; afirmou que o esvaziamento financeiro deveu-se menos ao programa governamental para ajustar as contas públicas e o pagamento da dívida externa do que à decisão política de reorientar os investimentos para o Projeto; provou-se que há um movimento para a inclusão efetiva da sustentabilidade na nova PDN (Política de Defesa Nacional) e; finalmente, argumentou-se a favor da necessidade de integrar o PCN ao sistema de produção de informações do SIVAM entendido como um novo enfoque sobre a defesa nacional na Era da Informação, e que é necessário para a vigilância da região.

O presente trabalho tem a intenção de analisar as discussões em torno da dimensão territorial no planejamento estatal. Essas discussões não são recentes, elas emergiram no cenário nacional em decorrência também das questões relacionadas a um conjunto de fatores que surgem como imposição do processo de acumulação flexível e globalizado, que busca produzir espaços homogêneos. Nesse momento o próprio papel do Estado, enquanto promotor do desenvolvimento é redefinido, alterando assim, sua relação de poder na produção do espaço, estabelecendo com isso, uma correlação de força com a sociedade. Todavia as questões que envolvem o planejamento recente no Brasil passam pela resolução de pontos cruciais, que estão diretamente ligadas às estratégias de intervenção do Estado a partir de uma lógica territorializada, que em primeiro lugar tem a região como ponto de partida. Nessa perspectiva se faz necessário pensar conceito de região e de território inseridos na dinâmica de planejamento territorial/regional. A tese apresentada neste trabalho demonstra que mesmo havendo um intenso esforço na elaboração dos PPAs e, consequentemente, dos planos e programas a eles ligados, no que se refere à introdução de um “moderno” planejamento público, a partir da introdução da concepção de território e demais instrumentos de execução e avaliação, quando se analisa o orçamento-programa percebe-se que os mesmos seguem outra lógica regionalizada de alocação de recursos, obedecendo a Constituição Federal, tanto no que se refere aos programas finalísticos, quanto ao de apoio às políticas públicas e áreas especiais. Assim, o orçamento segue uma dinâmica regionalizada, enquanto os planos e programas seguem uma dinâmica territorial. Enquanto o orçamento-programa estabelece a alocação de recursos seguindo o critério de divisão regional do IBGE – que divide o Brasil em cinco regiões. Os estudos da Dimensão Territorial para o Planejamento que orientam os PPAs, destacando, principalmente o 2008 – 2011 buscam estabelecer programas de desenvolvimento a partir da criação de inúmeros territórios. Passando assim, a desenvolver um sério problema na dinâmica do planejamento público brasileiro, que é o descompasso entre Plano – Orçamento – Programa, negando, com isso, a concepção de integração presente nos mesmos.

OBJECTIVE: The aim of this study was to identify the procedures adopted by Brazilian orthodontists in the following situations: extraction space closure, anchorage control in case of necessary anchorage for group A and frequency of skeletal anchorage use, especially in the upper jaw. METHOD: A questionnaire was sent to the e-mail address of all dentists registered in the Brazilian Federal Council of Dentistry. RESULTS: The results showed that most Brazilian orthodontists usually perform extraction space closure by means of sliding mechanics. The use of palatal bar, inclusion of second molars in the archwire and space closure performed in two phases are the most used techniques for anchorage control in the upper jaw. The skeletal anchorage is referenced by 36.5% of specialists as a routine practice for the upper jaw anchorage. CONCLUSIONS: There is a wide variety of procedures adopted by Brazilian orthodontists for orthodontic space closure and anchorage control.

The Gir cattle breed (Bos indicus) is an important genetic resource for milk production throughout the tropics. The small number of Gir animals introduced in Brazil, rapid dissemination of this breed recently, and the intensification of selection practices could contribute to increase of inbreeding level and reduce genetic diversity in this population. The population was analyzed in terms of pedigree completeness level, inbreeding coefficient, coancestry, generation interval, effective population size, effective number of founders and ancestors, among others. Despite the low mean inbreeding (around 2%), minor problems were identified in the population structure of the Brazilian Gir cattle, e.g., trend of narrower bottlenecks in the pedigree in recent years. The effective population sizes based on inbreeding (94) or coancestry (165.9) as well as the effective number of ancestors (76) and founders (143) were relativity high. The major subdivision of the Gir breed was observed between 1993 and 2002 (dairy and dual-purpose herds, wide use of within-herd matings). In this period the level of inbreeding remained at a higher level, there was a small increase in coancestry and the number of equivalent subpopulations was approximately 6. After 2002, there was genetic exchange between subpopulations, reduction in the average inbreeding, pronounced increase in the average coancestry, and the number of equivalent subpopulations was about 2. Furthermore, it was found that the mean generation interval of the population tended to increase in recent years (around 9 years). About 23% of genetic diversity has been lost since the first generation of founders. Based on the effective population size, number of equivalent subpopulations, inbreeding, coancestry, and loss of genetic diversity, the Gir population is still highly structured, but there is ample room for artificial selection. The results regarding the effective number of founders and ancestors in the present population demonstrate the existence of bottlenecks in the pedigree and indicate the need for population structure monitoring. Nevertheless, the Brazilian Gir breed can perfectly face a breeding program with high selection intensity. (C) 2014 Elsevier B.V. All rights reserved.

It has become evident that policies aimed at mitigating the growing water resources and water use conflicts in Brazil are crucial. The municipality of Extrema in Minas Gerais state in Brazil pioneered the first Brazilian municipal PES initiative (Conservador das Aguas program), based on the relationship between forests and the benefits they provide. This study aimed to assess soil loss in the Posses sub-basin, where the Conservador das Aguas program began. Additionally, we aimed to determine the potential that this PES initiative has for soil conservation, as well as to minimize the soil losses as a function of forest area size and location in order to propose a technical approach for implementing PES. In this sense, considering the prescribed conservation practices, land use situation, and soil cover in the Posses sub-basin, we analyzed the effectiveness of the Conservador das Aguas program before and after implementation in relation to reduced soil loss under 36 different land use and soil cover scenarios. We used a geographic information system (GIS) for spatializing and producing different information plans and the Revised Universal Soil Loss Equation (RUSLE) for estimating soil loss. As a result, we found that minimization of soil loss may be obtained by adopting pasture conservation practices. Additionally the expected average soil loss in the Posses sub-basin under conditions of land use and soil cover, before and after implementing the water conservation program was 30.63 and 7.06 Mg ha(-1) year(-1), respectively.

Purpose - This study examined the relationship between environmental management practices developed at a campus of a Brazilian university (University of Sao Paulo) and the greening of its organizational culture. The paper aims to discuss these issues.Design/methodology/approach - This article presents a theoretical background based on the concepts of environmental management, organizational culture and environmental management in higher education institutions. The main framework of this research is the model proposed by Harris and Crane.Findings - The studied university has an environmental management program that is sometimes constrained in the following ways: the university bureaucracy and hierarchy; the main performance indicators for lecturers and professors are based on scientific production and publication, giving them little time for complementary activities; and some units develop their own environmental management practices, but they are not disseminated as best practices for use by other units. Some academic units showcase the proactive actions of professors who incorporate environmental management into their daily activities. The general perception is that the phrase environmental management is almost synonymous with solid waste management.Originality/value - This research details the first Brazilian application of the Harris and Crane model. It contributes an original analysis of environmental management and green organizational culture of a Brazilian university, an organizational type that has seldom been studied to date.
