Currently the mobile services represent an essential tool in daily life of the population. However, while offering greater convenience to its users, there is growing concern about the harmful effects to human health, derived from daily exposure of the public to electromagnetic fields from radio base stations (RBS), since even today, there is no study proving that longterm exposure to low-level fields are not harmful to health. In Presidente Prudente has not been a study reporting values of measurements of electromagnetic fields from base stations installed in the city. Based on these data, this study aimed to assess the levels of electromagnetic exposure in the city of Presidente Prudente regarding recommended by international bodies, as well as propose measures that can reduce public exposure to electromagnetic fields. For measuring values of electromagnetic fields, we used appliance Electromagnetic Field Meter Portable Digital - DRE-050, the Instrutherm, following the methodology suggested and adapted from the Adilza Condessa Dode’study. In total, 49 points were mapped corresponding to the areas at risk of exposure to electromagnetic fields generated by the substations of power grid, transmission towers and telecommunication towers located in the city of Presidente Prudente (SP)

A fisiopatologia da esquizofrenia parece envolver uma complexa interação entre vulnerabilidades genéticas e fatores de risco ambientais. O uso de Cannabis tem sido apontado como um destes fatores, que contribui para o surgimento de sintomas psicóticos em indivíduos predispostos e piora o curso da doença pré-estabelecida. O sistema endocanabinóide está envolvido neste processo, podendo apresentar possíveis implicações na manifestação de sintomas. O presente trabalho teve como objetivo geral verificar se variantes dos genes CNR1 (codificador do receptor endocanabinóide tipo 1) e AKT1 (codificador de proteína serina-treonina quinase), individualmente ou interativamente, e o uso de Cannabis podem ser fatores de risco para a esquizofrenia e para a refratariedade ao tratamento com antipsicóticos. Foram estudados 202 pacientes portadores de esquizofrenia e 277 indivíduos saudáveis. Os polimorfismos rs1049353 (G/A) e rs806380 (A/G) do gene CNR1 e os rs2494732 (C/T) e rs1130233 (A/G) do gene AKT1 foram genotipados por meio da técnica de PCR (polymerase chain reaction) em tempo real com sistema de detecção Taqman®. Tais polimorfismos foram correlacionados ao diagnóstico de esquizofrenia e a outras variáveis, tal como o uso de Cannabis, resposta ao tratamento e subtipos da doença. Também foi realizada análise de estratificação populacional a partir de marcadores genéticos escolhidos para a população brasileira a fim de correção estatística de fatores confundidores relacionados a diferenças étnicas. Foi visto uma influência positiva da idade de acometimento em pacientes refratários quando comparados com os pacientes respondedores (p = 0,006), confirmando os dados da literatura que sugerem uma idade de acometimento mais precoce da doença em portadores de esquizofrenia refratária. A interação dos genótipos AA do polimorfismo rs806380...(Resumo completo, clicar acesso eletrônico abaixo)

In 2004 two trading environment for contracts of purchase and of electricity energy were established, the Regulated Contracting Environment (RGE) and the Free Contracting Environment (FCE). In the first one, consumers can only buy their energy directly from local electricity distribution, and in the second one, consumers can choose their delivery, amount and type of energy that they will burn through bilateral contracts. Thus, before deciding to migrate to the FCE, it is necessary understanding the rules of marketing, the risk involved and the economic viability of the two markets so can determine which environment has more benefits to the consumer. This paper aims to offer tools to support takeover decision of potentially free costumers, who have the option to migrate to market in order to evaluate the benefits and disadvantages of each market. This paper has also considered the new rules of the third rate cycle, where consumers can opt for green tax. The methodology presented is based on calculations of spending with energy and the risk of flag in captive market and free market in one year

The problem of flooding in urban areas exist in many cities and their causes are as varied as the areas of occupancy or Valley weatherproofing Fund areas of infiltration in the drainage basin. The anthropic activity come triggering changes and impacts on the environment for a long time, and there is a growing need to come up with solutions and strategies that minimize and reverse the effects caused these risk areas. Thus, the present work will address the case study in São José do Rio Preto-SP that is an exception, since the area that is considered of risk lies in the Centre, unlike most lying on the outskirts. This will also analyze the processes of urban expansion and the situations of social and environmental vulnerability, including their interrelations in urban scale. The physical study of the area will serve as an important basis for the work, but it will focus mainly on the population and the problems which this is being in hazardous areas. We will not join a single methodology, wharever, we will follow our knowledge to adapt what we feel that fits better, every time. The importance of this study is that in addition to identifying the problems which the local population suffers with floods, lists measures that minimize the environmental impacts arising through the fostering of public policies

O aumento da incidência de Doenças Sexualmente Transmissíveis (DSTs) em alunos do ensino fundamental e médio está ocorrendo no mesmo período em que se dá o crescimento da prevalência de consumo de etanol nesta faixa etária. Alguns estudos têm demonstrado a relação entre o uso de etanol e comportamentos sexuais de risco na adolescência. O aumento do número de publicações das relações entre o uso de substâncias psicoativas e as DSTs revela a crescente preocupação dos pesquisadores da área de saúde mundial com esses dois problemas importantes. Essas questões atingem uma camada importante da população – os adolescentes – podendo interferir no desenvolvimento desses indivíduos que constituirão a população adulta e produtiva da sociedade no futuro. Há muitos trabalhos de conscientização contra o alcoolismo ou DSTs visando o público jovem, porém há poucos que correlacione os dois temas. Portanto, o presente trabalho se propôs a estudar a relação entre o consumo abusivo de etanol, como substância psicoativa, e o comportamento sexual de risco através do levantamento do perfil de estudantes do Ensino Médio em uma Escola Estadual da cidade de Botucatu, evidenciando a real importância de adoção de estratégias pedagógicas mais efetivas que trate dos temas em questão. O uso de etanol nessa população mostrou estar associado ao aumento no número de estudantes com vida sexual ativa, diminuição na idade de iniciação sexual, menor uso de preservativo e atos de arrependimento e violência. Conclui-se, assim, a necessidade da escola, enquanto espaço privilegiado da informação e saber, ater-se em programas que tratem dos temas em questão (drogas e sexualidade) oportunizando o diálogo e a reflexão

Com o ritmo acelerado que a vida moderna exige, é cada vez mais evidente a necessidade do ser humano em buscar novas experiências para que os façam sentir emoções e sensações inéditas, não existentes no dia a dia. Com isso a busca por esportes de risco vem sendo cada vez maior, visto que muitos destes esportes satisfazem os desejos por novas experiências. Acredita-se que haja inúmeros fatores atrativos que levam os indivíduos a aderirem a essas praticas. No presente estudo foi verificado que fatores psicológicos estão fortemente presentes, o medo e a ansiedade mostram-se fatores atrativos, assim como o desejo de conhecer lugares novos, o que aponta para uma ligação direta com o turismo. A sensação de bem estar, satisfação, alegria e orgulho foi afirmada por maioria dos sujeitos, o que acaba levando os indivíduos a procurarem diversos esportes de risco, favorecendo a aderência a essas modalidades e a permanência nas mesmas.

The city of Guaratinguetá, SP, presents in its history, several instances of property damage and human losses, conditional on the event of flooding and mass movement of soil, resulting from the development of erosion processes. The extent and severity of these events that affect humans and their properties is the result of the illegal occupation of these areas as potential geohazard. Thus, it is of great importance to physical characterization and identification of such areas within the map of the same city as a way to minimize the effects and mitigate the consequences of these events. Thus, this graduate report presents a series of field campaigns, geotechnical laboratory testing, consultation with maps and satellite images, representative of the physical environment, and the city plan as a means conclusive for the delimitation of risk areas with potential for occurrence of erosion and / or flooding on the map representing the urban area of Guaratinguetá, SP. Also featured are the descriptions of the main characteristics of those areas identified as being at risk, along with proposals to avoid or minimize the impact of problems related to flooding and erosion processes on the local population

A doença de Parkinson (DP) é uma doença neurodegenerativa que afeta principalmente o controle motor com reflexos negativos no desempenho funcional de seus pacientes. Alterações no equilíbrio podem levar à diminuição da independência e funcionalidade. Alguns estudos evidenciam os benefícios do exercício físico, como alternativa nãofarmacológica para esses pacientes. Objetivo: O presente trabalho analisou e comparou os efeitos de dois programas de atividade física sobre o risco de quedas e o equilíbrio funcional em pacientes com doença de Parkinson. O presente estudo também teve como objetivo verificar a associação entre as variáveis clínicas e comportamentais. Método: Participaram do estudo 30 pacientes com DP idiopática entre os estágios I a III na escala de estagiamento clínico de Hoehn & Yahr, sendo distribuídos em três grupos: grupo de treinamento com pesos (GTP), atividade física generalizada (GAFG) e o grupo controle (GC). O período de intervenção para o GTP e o GAFG foi de quatro meses. As avaliações foram realizadas com os participantes na fase “on” da medicação. Para avaliar o equilíbrio dinâmico juntamente com o risco de quedas foi utilizado o teste Timed Up and Go (TUG) e, para analisar o risco de quedas foi utilizada a Escala de Equilíbrio Funcional de Berg (EEFB). As avaliações clínicas foram realizadas por meio da Unified Parkinson’s Disease Rating Scale (sub-escalas funcional e motora), escala de nível de gravidade da doença de Hohen & Yahr e Mini-Exame do Estado Mental (MEEM). O teste U de Mann-Whitney foi utilizado para comparação das variáveis analisadas entre os três grupos separadamente por momento do treinamento. Resultados: Apenas em relação à EEFB foram encontradas diferenças significativas entre os grupos, com pior desempenho para o grupo controle (GC). Conclusão: Foi possível observar que: os pacientes...

The city of São Paulo has, since the beginning of the expansion of its urban sprawl, represented relations of conflicts and contradictions between society and nature. Once the way society relates to nature is defined by how the social agents themselves correlate in certain social and historical contexts, the ways of interaction between the social and natural elements will be different according to the forms of production and appropriation of the urban space. Even more evident is the case of the great national metropolis, given its demographic dimensions and historical conditions, the process of urban expansion follows a logic where spaces of better quality for housing are occupied by those of better financial conditions. Thus, although there are exceptions, the poorest people live in places less desirable, in less resilient environments of lower environmental quality, relating to nature and its phenomena with greater risks. These risks are reflected here as recurring flooding, mudslides and landslides for which the rain is constantly blamed. So we have a situation where it is clear that a weather phenomenon differently interacts with different social groups. In this context, the study was conducted to compare extreme events occurred in two regions of São Paulo: the Freguesia do O, in the north side, and M'Boi Mirim, in the south side. Both are regions with large number of risk areas and are in the same urban climate unit. However, they present different conditions of social vulnerability. With the investigation of each extreme rain event occurred in the two regions, in the period of 2000-2010, supplemented by field research, we tried to observe how far the rain, with his intensity and volume, can, in fact, be related to the accidents.

The main objective of the presented study is the development of a predictive interval type-2 fuzzy inference system in order to estimate the mortality risk for a newborn, to be used as an auxiliary tool for decision making in medical centers where there is a lack of professionals for this purpose and, afterwards, to compare its performance to a type-1 fuzzy system. The input variables were chosen due to their acquisition ‘simplicity, not involving any invasive tests, such as blood tests or other specific tests. The variables are easily obtained in the first few minutes of life: birth weight, gestational age at delivery, 5-minute Apgar score and previous report of stillbirth. Databases from the DATASUS were used to validate the model. 1351 records from the city of São José dos Campos, a mid-sized city in the São Paulo state’s countryside, were considered in this study. Finally, an analysis using the ROC curve was performed to estimate the model’s accuracy

The Alzheimer’s dementia represents a clinical condition inherent to many chronic and neurodegenerative diseases that are usually related to a decline in the cognitive and physical functions. The objective of this experimental design research was to analyze the effects of a regular and systemized physical activity program over the cognitive functions, balance and risk of falls of elderly with Alzheimer’s Dementia (DA). The sample was made of 16 elderly with DA, distributed in two groups: a) intervention group – GI (9 subjects that had participated in a program of physical activity, that consisted of 3 weekly sessions of 60 minutes each, in alternated days and with a duration of 6 months); b) control group – GC (7 subjects that did not participate in the program of physical activity). Both groups maintained the doctoral and pharmacological assistance routine. The subjects passed through two different evaluations (pre and post-intervention) the questionnaire (Mini-exam of Mental State for cognitive functions) and motor tests (Berg Functional Balance Scale – EEFB, Timed Up-and-Go (TUG) time (TUGs) and steps (TUGp) and the test of agility and dynamic balance (AGILEQ) of the American Alliance for Health, Physical Education Recreation and Dance for elderly). The obtained results were, respectively in the pre and post-intervention moments: a) AGILEQ (GI = 39,1 ± 10,2 and 38,4 ± 8,9 and GC = 45,6 ± 16,7 and 59,9 ± 22,0 seconds) with the statistically interaction significant (ANOVA two-way; F1,14 = 32,07; p=0,01) between groups and moments; b) TUGs (GI = 9,8 ± 2,5 and 9,5 ± 3,3 and GC = 10,6 ± 4,5 and 12,7 ± 7,3 seconds) the test UMann Whitney did not appoint any significant differences between the groups in the post-intervention moment, however the analyzes of Wilcoxon evidenced a ...(Complete abstract click electronic access below)

The work consists of analyzing the risk management of investments by applying statistical concepts, economic and mathematical models considering the assets on the market on renowned financial institution. The assessment of these risks becomes increasingly interesting in view of minimizing your losses thus maximizing your chances of gains in both markets boom as extreme uncertainty, even with the sudden changes of scenery. Introducing concepts of investment funds, as well as the classification of the types of funds as funds management and equity, its guidelines, the concept of market investment funds. The types of assets comprising the investment funds, their taxation rules beyond the incidents that market widely used by investors and skilled people, both physical and legal, who keep their resources in this modality. With the historical data collected yields of investment funds of the Bank of Brazil, is an accomplished inflation adjustment and calculated the mean and variance for the verification of the model of Markowitz efficient frontier, a method used as investment analysis. This scan is used Matlab to obtain the set (or border) efficient portfolios. Once verified such data, there will be a critique of the Markowitz model as a quadratic programming and more coherent risk measures currently studied as VaR and CVaR minimizing the expected error, approaching our studies of current research. It is found that such studies have much to be explored, since there are many discussions about how effectively measure risk investments such as its characteristic and behavior, using a time series and volatility
