One hundred non-patient dentistry students aged 17 to 25, were interviewed through questionnaire and were clinically examined in order to asses the prevalence and degree of severtty of Craniomandibular Dysfunction, through indeces which are subdivided into three classes: anaminestic index, clinical dysfunction index, and occlusal index. The following variables were introduced to the original indeces: sex, age, and whether the subjects had or had not received orthodontic treatment. The results showed that 42% of the subjects presented mild subjective symptoms whereas, no one showed severe subjective symptoms. Women, as well as the older subjects, showed a higher trend to presenting more subjective complaints. Subjects, whether treated orthodontically or not, showed a similar trend to having dysfunction symptoms. Fifty-six per cent of the subjects presented some score of clinical dysfunction, 25% of them showed moderate or severe clinical dysfunction. Women showed a statistically significant higher index. The older subjects trented to have indeces with more severe degrees. Orthodontic treatment suggested to have no influence on the clinical dysfunction index. Sixty-six per cent of the subjects showed a mild occlusal index and 11% a severe occlusal index. Sex, age, and orthodontic treatment did not show any significant difference as to the presence or absence of malocclusion

The goal of this research was to characterize written stories, produced by students, without complaint of language development (oral and written), from pictographic support. In a specific way, it has been searched, in those stories, elements that could grant coherence, applying that performance with the participants’ profile variables. It was characterized as a descriptive-exploratory study, held at a rural municipal school in the State of Parana. Twenty-one (21) students of both genders and ages between seven and nine years old have participated in this study. Data collection consisted of two narratives requests: one oral, after being released, to the child, four pictures placed in sequence to form a story, and one written. This writing production had been taken for the analysis. The results have indicated that most children (71.42%) managed to produce coherent stories, seventeen (80%) in story 1 and thirteen (61%) in story 2. As to the relation of that coherence with the students’ profile in story 1, there has been no statistically significant association, for none of the analyzed variables (gender, age and education), whereas there has been a statistically significant association with gender in story 2 (p-value 0.027). It is considered that the use of the pictographic support in developing stories have been confirmed as a facilitating strategy for its construction, for it has enabled the production of coherent narratives.

Examine the effects Global Postural Reeducation, (GPR) in hyperkyphosis and respiratory variables in the elderly was the objective in the research. For this, two elderly participated, one is 62 years old (voluntary 1) and another is 66 years old (voluntary 2), without lung, heart, kidney and/or skeletal-muscle diseases diagnosed. The volunteer have been assessed for Quality of Life (QOL) through the questionnaire SF-36, the degree of toracic kyphosis, the muscular respiratory strength and the thoracic-abdominal mobility. The GRP treatment consisted in eight sessions applied, once one hour each session. After the eight sessions the volunteer were reevaluated. The data concerning assessments before and after treatment were analysed describly. According to the results there was an improvement in the degree of kyphosis in both volunteers, highlighting voluntary 2. Respiratory variables also improvements after treatment. In relation to the Quality of life in most areas there has been an increase in scores indicating improved QOL. These data showed that the GPR has been effective to decrease the level of kyphosis, improves respiratory variables and the quality of life in the elderly treated. However, further work with a greater number of subjects must be carried out to analyze the effectiveness of therapy in the elderly.

The effort test can be used to assess functional capacity, clinical hemodynamic and metabolic response at the effort, the risk of postoperative pulmonary complications and to assess the response of patients with lung diseases submitted to physiotherapy treatment. Among the stress tests we highlight the Six Minute Test Walk (6 MWT) and Stair Climbing Test (SCT), because they are easy to use and low cost. Especially the SCT is widely used in patients preoperatively. Objective: To compare the effects of six minute walk test and stair climbing test under the hemodynamic and oxygenation in healthy adults. Methods: We conducted a study with healthy subjects above 50 years. The fi rst performed was 6 MWT in quick step with encouragement, in a plan corridor of 30 meters, where the shade was determined the distance walked in 6 minutes, after 6 MWT was performed de SCT with encouragement, on a ladder in shade, consists of 44 steps, with 4 bids and bid by 11 steps, each step measured 16 cm in a total of 7.04 m of height, where the rise time was clocked. Before and after the two tests were measured respiratory rate, pulse, blood pressure and oxygen saturation. Results: We evaluated 21 patients with age 59.6 ± 5.4 years, 5 men and 16 women. The average distance covered on the 6MWT was 496.4 ± 102.2 meters and the average time in SCT 22.6 ± 5.4 seconds. The variables pulse, respiratory rate, systolic blood pressure and Borg scale presented a signifi - cant increase after the tests, however the variables oxygen saturation and diastolic blood pressure did not change signifi cantly. Conclusion: The variables pulse, respiratory rate, systolic blood pressure and Borg scale tests increased after six-minute walk test and stair climbing test but with greater signifi cance after the stair climbing test. Oxygen saturation and diastolic blood pressure did not change signifi cantly after the tests.

No Brasil ocorrem aproximadamente 20.000 acidentes ofídicos anuais, sendo um grande problema de Saúde Pública. As serpentes do gênero Bothrops são responsáveis por aproximadamente 90% dos casos, destacando-se a espécie Bothrops jararaca, responsável por aproximadamente 93% dentre os acidentes botrópicos. O presente trabalho tem como objetivo caracterizar o perfil epidemiológico dos acidentes causados por B. jararaca e avaliar possíveis influências das variáveis biológicas encontradas nos exemplares que causaram acidentes no Estado de São Paulo. Para realização desse estudo foram tomadas como base espécimes de Bothrops jararaca que causaram acidentes nos períodos de 1959 a 2011 preservadas na Coleção Vital Brasil do Instituto Butantan. Essas serpentes (N=1526) foram dissecadas e analisadas. Dados relativos à epidemiologia dos acidentes, período de atividade sazonal, processos reprodutivos e dieta foram coletados. O levantamento e análise dos dados dos acidentes mostraram que 71% dos acidentes são causados por filhotes, enquanto apenas 29% são causados por adultos. Análises preliminares mostraram que fêmeas causaram mais acidentes do que machos independente de serem filhotes ou adultos. O padrão sazonal dos acidentes foi diferente entre os filhotes e adultos de B. jararaca, o que deve estar relacionado às atividades de forrageamento, termorregulação e principalmente aos eventos reprodutivos. O perfil epidemiológico dos acidentados apontou uma maior incidência de acidentes em situações de trabalhos rurais, no caso, a maioria dos acidentados são homens jovens que foram atingidos nas mãos durante o dia

Six species of the genus Callithrix can be found across the Atlantic Forest extension, being the Callithrix geoffroyi, Geoffroy`s marmoset, the least studied species. The objective of this study is to investigate the behavioral aspects of the species in captivity, and how the environmental enrichment techniques influence those behaviors. To this end, we have studied three specimens of C. geoffroyi, in captivity at Municipal Zoo of Piracicaba, São Paulo. The enclosure includes a 37m2 with under masonry, concrete platforms with external deep, trunks, a floor of grass and soil, e grid in their other three sides. The sampling method was focal per time interval, with records every 30 seconds in sessions of 30 minutes, totaling 30 hours for each animal, which were distributed in a baseline phase, an environmental enrichment phase and post-enrichment phase (n = 3660 records in each phase). The twelve enrichment techniques were applied: the physical environment (branches for perches and hoses fabrics for bedding and vanishing points), cognitive (radio, mirror, puzzle food) and food (insects, flowers and eggs hidden, wrapped). Initially, to determine the period of greatest activity of marmosets, we investigated the pattern of activity for three days (9:00 am to 17:00 pm) consecutively at intervals of 15 minutes, recording the number of active and inactive individuals. The 495 records signaled greater activity in the morning, then selected period for the completion of this work. The ethogram comprised 16 behaviors. The inactivity was the predominant phase behavior baseline and post-enrichment with a significant decrease (h=8,62, p <0.01) in the enrichment phase, and a significant increase in the post enrichment (h=18,15, p <0.001). The same was seen for the use of substrate (grid and ground vs. Trunk and concrete, h=5,09, p <0.001 and h=3,98, p <0.05)... (Complete abstract click electronic access below)

Muscle fatigue is described as a cause of injuries among the many related to the running practice. Therefore, the purpose of this study was to analyze the behavior of the amplitude (RMS) and median frequency (MF) of EMG signal of the iliocostalis (CI), rectus femoris (RF), vastus lateralis (VL), vastus medialis (VM) biceps femoris (long head) (BFCL), tibialis anterior (TA) and gastrocnemius (lateral) (LNG) from the right lower limb, and the behavior of the parameters of amplitude (AP) and frequency (PF) spent in different percentages of the maximum speed during incremental protocol of treadmill running. 10 volunteers participated in this study, athletes, male, aged between 18 and 30 years with no history of injury in lower limbs and similar anthropometry. The protocol consisted of a treadmill test with initial velocity of 10 km.h-¹ and increments of 1 km.h-¹ each three minutes until volitional exhaustion, without rest interval. Synchronized collections were made of electromyographic and kinematic data. The signals were obtained through an acquisition module of biological signals (Telemyo 900 - Noraxon - USA) and software (Myoresearch - Noraxon - USA) calibrated with a sampling frequency of 1000 Hz, gain 2000 times. The raw data were filtered with a 60Hz notch filter, high pass and low pass 20Hz to 500Hz. To capture the image was used a digital video recorder (model NV-GS320, PANASONIC brand), and for image scanning and kinematic data collection was used the software Peak Motus 9.0 (ViconPeak). To obtain the values of RMS and FM analyzed the last ten passes of each speed through a specific routine (Matlab). To obtain these variables AP (m) and FP (stride I min) were analyzed for the last ten past each speed, using specific software (Peak Motus 9.0). After verification of data normality (Shapiro-Wilk) and homogeneity of the data (Levene), the comparison ...(Complete abstract click electronic access below)

O contexto esportivo é repleto de muitas manifestações psicológicas. Para se ter sucesso é necessário que ocorra uma grande preparação destes atletas, que devem estar preparados fisicamente, tecnicamente e taticamente para responder às necessidades do esporte, buscando sempre a vitória e a melhor performance nas competições desportivas. A Psicologia do Esporte vem desenvolvendo programas de treinamento psicológico envolvendo técnicos, treinadores e atletas na busca de melhor desempenho nas competições. Hoje em dia o voleibol é um dos esportes mais praticados e assistidos no mundo inteiro, sendo no Brasil o segundo esporte mais praticado. O estado emocional se altera tanto em um período pré-competitivo, onde a incerteza de futuros acontecimentos provoca uma ansiedade, tensão e certo desconforto, quanto no momento da competição e também no período póscompetitivo. O sentimento de vergonha também é manifestado em muitas ocasiões. Várias são as definições encontradas para essa emoção: sentimento penoso de desonra; humilhação; rebaixamento; sentimento de insegurança provocado pelo medo do ridículo; embaraço; indignidade; timidez; acanhamento; sentimento de desconforto, entre outras. . A pesquisa buscou analisar teórica e praticamente as alterações emocionais de atletas em suas funções esportivas. Foi realizada com uma equipe de voleibol feminino, onde se aplicou um questionário fechado, a 21 atletas, com idades entre 13 e 16 anos. Verificou-se com que freqüência as manifestações dos sentimentos de vergonha e ansiedade ocorriam e possivelmente prejudicavam o desempenho das atletas. Após análise dos resultados pode-se concluir que as manifestações de ansiedade foram mais evidenciadas se comparadas as de vergonha. Notamos que, as preocupações quanto ao desempenho e aos erros que podem ser cometidos são muito evidenciados na equipe. A vergonha-meta... (Resumo completo, clicar acesso eletrônico abaixo)

Este trabalho teve como objetivo principal avaliar a influência de um período de chuvas intensas sobre as assembléias zooplanctônicas e variáveis limnológicas dos reservatórios de Chavantes e Salto Grande. Em função das precipitações elevadas, o tempo de residência da água durante o período de verão 2009/2010 (período imediatamente anterior às coletas) foi o mais baixo da década (1999-2010), tanto para Chavantes como para Salto Grande. As variáveis analisadas foram: transparência, temperatura, oxigênio dissolvido, pH, condutividade elétrica, turbidez, material em suspensão, clorofila a e nutrientes (nitrogênio total, fósforo total e silicato dissolvido). A turbidez foi a variável que mais se alterou, apresentando um aumento notável com o incremento das chuvas. A transparência e o material em suspensão também apresentaram grande alteração, sendo que a primeira variável diminuiu com a maior quantidade de chuvas e a segunda aumentou. Os valores de fósforo total e silicato dissolvido diminuíram com o aumento das chuvas, sendo que para o silicato a variação foi mais expressiva e para o fósforo o decréscimo foi mais acentuado em Chavantes do que em Salto Grande. Para as outras variáveis limnológicas, bem como para o zooplâncton, os dois reservatórios apresentaram comportamentos diferentes quanto às alterações pluviométricas. A temperatura variou mais em Chavantes. Condutividade elétrica e pH apresentaram relação com a temperatura e o oxigênio dissolvido não teve muita alteração com as mudanças pluviométricas. Os atributos analisados para o zooplâncton foram riqueza, composição, abundância (total, por táxon e das fases de desenvolvimento) e diversidade. Comparando os dois reservatórios estudados, foi observado que em Chavantes o aumento pluviométrico teve efeito muito ...(Resumo completo, clicar acesso eletrônico abaixo)

In the past years, soya has increased itself as the mean agro export culture in Brazil, encouraging the expansion of its agricultural frontier throughout the country. Brazil is the second biggest soya producer around the world, with a 59,8 million ton production in 2008, according to the Instituto Brasileiro de Geografia e Estatística (IBGE), only behind United States. Around the country, the four leading producer states are Mato Grosso, Paraná, Rio Grande do Sul e Goiás. Therefore, geotechnologies may be used to monitor use and soil occupation in various analyzes periods. In this review, the tools are important to illustrate the soya production areas and also the weather behavior around its production evolution in the territory through the years. Its utilization can contribute to the evolution and optimization around real time monitoring of the Agricola cultures, without being necessary to be in the area with a low financial cost. Generally, this information is strongly important for decision makers in both government and private sector, as soon as the achievement information regards the quantification of area, yield and development of agricultural crops are essential to the economic behavior of culture during the season and even beyond. By obtaining data regarding climate crops 2008/09 and 2009/10, held the climatic water balance calculation based on the dynamics of water storage in soil temperature and precipitation data, interpolation of the data through the interpolator (IDW) that generated thematic precipitation maps. Overall, the use of geotechnology to monitor agricultural areas, can strongly contribute to this monitoring, generating raw material for further analysis at low cost

A inatividade física é uma das principais causas de morte no mundo, e um dos principais fatores de risco para doenças não transmissíveis. Os fatores de risco destas doenças podem ser prevenidos com modificações no estilo de vida, que reduz eventos cardiovasculares e aumenta a sobrevida de pacientes portadores ou em risco de coronariopatias. Entendendo de como estes agentes casuais se predispõem ao surgimento de cardiopatias, o acompanhamento de fatores de risco ajudam na identificação de sinais antecessores à doença, que podem ser modificados, atenuados e até mesmo revertidos. O objetivo do presente estudo foi de verificar a influência de um ano de prática regular de Atividade Física nas variáveis bioquímicas (bioquímicas (glicose, triglicérides, HDL, LDL, e colesterol total), circunferência de quadril e abdominal e Indice de Massa Corporal (IMC) de seus praticantes. Participaram do presente estudo 25 mulheres com idade superior a 40 anos participantes iniciantes do Programa de Exercício Físico na Atenção Básica da cidade de Rio Claro-SP. As atividades foram realizadas com frequência de três vezes por semana, em sessões de 60 minutos. Foram realizadas três análises laboratoriais (início, após 4 meses e um ano de intervenção) das variáveis bioquímicas (glicose, triglicérides, HDL, LDL, e colesterol total). Os principais resultados do presente estudo demonstraram que após quatros meses de intervenção a circunferência abdominal e o LDL apresentaram menores valores do que no início do programa. Entretanto, após um ano de intervenção a circunferência do quadril, abdominal, LDL, glicose e colesterol total apresentaram maiores valores do que quando comparado com os valores após os 4 meses. Com base nos resultados antropométricos percebe-se que houve melhores resultados aos quatro meses de intervenção do que com um ano de intervenção. Provavelmente o que ocorreu no caso do presente estudo se deve pela...

This research is aimed at discussing the ways in which social agents influence global warming, analyzing the discourse of social actors involved in the debate on climate change, since there is a wide divergence in the scientific community about how man is able to modify the climate on a global scale. In fact the debate that permeates the issues beyond the limits of science and enter into a political-economic framework that takes extraordinary proportions. This emphasis can be very unscientific in the fundamental design concepts, or even creating a trivialization of the media. The main way to convey these concepts is to disclose them in the media, but the media has enormous power to transform the concepts and often manipulate the news by creating a common sense goes against the interests of the scientific community. Thus was conducted extensive research in major newspapers and magazines that move in the country. We surveyed the first two papers which were: “Folha de S. Paulo” and “O Estado de S. Paulo”, during the period from January 2000 to December 2008, totaling 3285 units for the newspaper Folha and 2555 for the newspaper Estadão. Subsequently a survey was made of data published in two journals that move at the national level, and these are the magazines VEJA and ÉPOCA for the same period. By performing these steps, it was concluded that several factors involving the media and climate change, such as topic relevance, types of approaches, perspectives of analysis, the staff development, supplies, among other factors of utmost importance for building news. As a result we can say that the media in fulfilling its role of mediator scientific, disclosing only a vision that permeates the scientific debate. The newspaper media, especially newspapers, has an informative and instantaneous. Often this preoccupation...(Complete abstract, click electronic access below)
