The Wii Balance Board (WBB) began to be investigated as a low-cost alternative for assessing static balance in vertical posture. However, studies employed methodological procedures that did not eliminate result variability between the tests and equipment used. Objective: Determine the validity and reproducibility of the WBB as an instrument for assessing static balance in the vertical position, using simultaneous data analysis and superimposed equipment. Methods: This is an accuracy study of 29 healthy young individuals of both sexes aged 18 to 30 years. Subjects were assessed 24h apart (test-retest), using unipodal and bipodal support tests, with eyes closed and open. To that end the WBB was placed on top of a force platform (FP) and data (postural sway) were collected simultaneously on both devices. Validity and reproducibility were analyzed using the interclass correlation coefficient (ICC). Finally, Bland-Altman analysis was applied to assess agreement. Results: The sample was composed of 23 women and 6 men, with mean age of 24.2±6.3 years, 60.7±6.3 kg and 1.64±4.2 m. The validity of the WBB compared to the FP was excellent for all 4 tasks proposed (ICC = 0.93 0.98). The reproducibility analyzed by test-retest was excellent for the bipodal support tasks (ICC = 0.93-0.98) and only moderate for the unipodal support tests (ICC = 0.46 0.70). Graphic analysis exhibited good agreement between the devices, since most of the measures were within the limits of agreement. Conclusion: this study proved the validity and reproducibility of the Wii Balance Board as an instrument for assessing static balance in vertical posture, using simultaneous analysis with superimposed equipment. Thus, the WBB has been increasingly used by physical therapists and other health professionals in their clinical practice, as both a rehabilitation and assessment tool

The way to deal with information assets means nowadays the main factor not only for the success but also for keeping the companies in the global world. The number of information security incidents has grown for the last years. The establishment of information security policies that search to keep the security requirements of assets in the desired degrees is the major priority for the companies. This dissertation suggests a unified process for elaboration, maintenance and development of information security policies, the Processo Unificado para Políticas de Segurança da Informação - PUPSI. The elaboration of this proposal started with the construction of a structure of knowledge based on documents and official rules, published in the last two decades, about security policies and information security. It's a model based on the examined documents which defines the needed security policies to be established in the organization, its work flow and identifies the sequence of hierarchy among them. It's also made a model of the entities participating in the process. Being the problem treated by the model so complex, which involves all security policies that the company must have. PUPSI has an interative and developing approach. This approach was obtained from the instantiation of the RUP - Rational Unified Process model. RUP is a platform for software development object oriented, of Rational Software (IBM group). Which uses the best practice known by the market. PUPSI got from RUP a structure of process that offers functionality, diffusion capacity and comprehension, performance and agility for the process adjustment, offering yet capacity of adjustment to technological and structural charges of the market and the company

Coastal and marine protected areas are created to protect habitat, avoid biodiversity loss, and to help maintain viable fisheries. However, most of these areas in tropical countries occurs in impoverished regions and directly affect the livelihood and survival of coastal communities which directly depend on fisheries and shellfisheries. Therefore, socioeconomic and conservation goals overlap. In this context, fishers should have a central place in resource management. They are critical resource users and their behavior directly affects the system. Shellfish resources are important sources of food, employment and income to fishing communities in Latin America. But despite its widespread use for food and income, there is an urgent need of more research on shellfish management. This research discusses the artisanal fisheries of Venus clam (Anomalocardia brasiliana) (Gmelin, 1791) (Bivalvia: Veneridae) in Brazil, and points out strategies to improve the system. Venus clam is a small and commonly exploited species for food and income on the Brazilian coast. This research was carried out at Ponta do Tubarão Sustainable Development Reserve (Brazilian Northeast coast), where there was no information available about who harvest, where or how much Venus clam has been harvested, despite this resource being exploited for generations. Clam fishery follows the pattern of socio-economic invisibility that general clam exploitation has in Brazil. Methods used were interviews, participatory monitoring and focal follow observation from January 2010 to May 2011. Results include: (a) the identification of shell fishers, (b) how harvest and meat processing are performed (mollusk beds, time spent, gross and net production), (c) the analisis of shell fisher income and their economic sustentability, and (d) the involvement of shell fisher families in data gathering and analyses for the first time. Based on the acquired knowledge, we propose a new institutional arrangement for clam fishery including co-management, fisheries agreement, compensatory arrangements and improvements for the Venus clam value chain such as the establishment of a minimum price for clam meat. This research also includes two other results: a general description for Venus clam harvesting in the Brazilian Northeast coast and a specific discussion about co-management of Venus clam in Brazil. The first one was possible through the meeting of several shell fisherwomen from other states during activities promoted by People of the Tides (PoT) project. PoT was an international initiative aiming to develop coastal communities that depend on mollusk for their livelihood. The second one is a comparison between PoT and Venus clam management at Pirajubaé Marine Extractive Reserve (Santa Catarina). It evaluates the success and failures of these only two initiatives involving co-management of A. brasiliana in Brazil

O objetivo do presente estudo foi desenvolver um snorquel (SNQ) de baixo custo para mensuração de parâmetros cardiorrespiratórios em natação. Para isso, a máscara do analisador de gases VO2000 (MASC) foi adaptada a um SNQ desenvolvido artesanalmente com espaço morto de 250ml. Oito participantes foram submetidos a dois testes incrementais (TI) em cicloergômetro utilizando a MASC e o SNQ. Os TI foram realizados até a exaustão voluntária e foram compostos por estágios de 3min com carga inicial e incrementos de 35W. em ambas as situações, amostras gasosas foram coletadas em intervalos de 10s para determinação dos volumes de oxigênio (VO2), gás carbônico (VCO2), ventilatório (VE) e mensuração da freqüência cardíaca (FC). A comparação dos parâmetros cardiorrespiratórios (VO2, VE, VCO2 e FC) mensurados com o SNQ e a MASC foi realizada com o teste t de Student para amostras dependentes, enquanto que o teste de correlação de Pearson e a análise gráfica de Bland e Altman foram utilizados para verificar as associações e concordância entre parâmetros. em todos os casos, o nível de significância foi de P < 0,05. A adequação das equações de correção para os valores provenientes do SNQ foi verificada pelos erros sistemáticos (bias), aleatórios (precisão) e acurácia (ac). Não foram observadas diferenças significativas entre os valores de VO2, VCO2 e FC obtidos com a MASC e SNQ. Os valores de VE mensurados com o SNQ foram significativamente superiores aos obtidos com a MASC. No entanto, todos os parâmetros apresentaram elevada concordância e coeficiente de correlação (0,88 a 0,97). Além disso, foram verificados reduzidos valores de bias (VO2 = 0,11L/min; VE = 4,11L/min; VCO2 = 0,54L/min; 8,87bpm), precisão (VO2 = 0,24L/min; VE = 11,02L/ min; VCO2 = 0,18L/min; 7,42bpm) e ac (VO2 = 0,27L/min; VE = 11,76L/min; VCO2 = 0,56L/min; 11,56bpm). Desse modo, pode-se concluir que o SNQ desenvolvido neste estudo possibilita a mensuração válida de parâmetros cardiorrespiratórios em natação.

O artigo reúne uma análise do impacto da arrecadação do Imposto Territorial Rural no período de 1995 a 1997 nos municípios paulistas de Bragança Paulista, Franca e Porto Ferreira frente à composição das receitas municipais. A análise é realizada com base nas legislações do imposto vigentes no período e realiza comparações de arrecadação e projeções tendo como referência os valores da terra nua arbitrados pela Secretaria da Receita Federal (SRF) e pesquisados pelo Instituto de Economia Agrícola da Secretaria de Estado dos Negócios da Agricultura e Abastecimento de São Paulo. Os resultados da pesquisa indicam percentuais de evasão fiscal que atingiram de 18% a 52% e inadimplência de até 31% e esse perfil de evasão se acentua quando a partir de 1996 a SRF deixa de estabelecer o valor da terra nua mínimo (VTNm) e passa a tomar como referência apenas os valores declarados pelo contribuinte.
