The aerial activities, leaps and slaps with parts of the body in the surface of water, are part of the behavioral repertoire of several species of cetaceans. Among them, the spinner dolphin, Stenella longirostris, shows greater diversity in such behavior. For the spinner dolphins of Fernando de Noronha, the aerial activities are classified as vertical and horizontal, with eight patterns to be noted (tail slap, head slap, motor boating, partial leap, leap, spin, tail over head and tail over head with spin) discriminated between these categories. Such behaviors can be used as a parameter to identify behavioral changes, as well as patterns of daily and seasonal activity. In this manner, this study aimed to characterize the frequency in performance of such activity while the dolphins were within the Dolphin Bay of Fernando de Noronha, and verify possible daily and seasonal hourly fluctuations on such behaviors. The data analyzed in this study was acquired during the period of January 2006 through December 2010, totaling 1431 days of observation from land set point, with 113027 aerial activities registered, daily average of 72,27 (SD=96,10). During 5478h and 54 min of observation the horizontal aerial activity was the most observed and rotation was the most executed pattern. Greater frequency of execution of aerial activity was observed in adults, but for both adults and calves, was observed a predominance of horizontal activities, with spin being the pattern most executed. Positive correlation was observed between the amount of aerial activity performed and the number of animals inside the Bay. Hourly daily fluctuation was observed in the expression of aerial activities by spinner dolphins, and was observed a peak of activity between 8h and 8h59min for the overall frequency relative of aerial activities, as well as for the categories and patterns. Seasonal differences were observed between the rainy and dry season with the greater amount of activity being observed during the rainy season. Nevertheless, the same profile of frequency relative of aerial activity was observed in both seasons with the peak amount being during the same period. When discriminated the aerial activities in categories and patterns, for both seasons, there was a similar pattern of hourly fluctuation; for most of parameters, higher frequency relative of execution of aerial activity remain between 8h and 8h59min

Music can be found in peculiar historical and social context with distinct functions, such as religious rituals, ethic-esthetic education of subjects, therapeutic elements, critic and maintenance of established patterns, among others. Considered as language, music acts on dialogue dimensions of the body, the senses, the affectionate-cognitive and of social interactions. Their uses reveal the social forces that cross the culture and constitution of subjectivities. The attribution of senses by the subjects to musical production reveals the cultural voices in dialogue, that circumscribe determined social places to them. Our aim in this work is to investigate the child musical appreciation, with children about 7 to 9 years old, and, by attributing uses and senses to music, unveil the voices that settle the places intended and assumed by infancy in contemporaneity The child constructs its musical appreciation through cultural access and mediation, possible by circulation in several socializing groups like family, school, church, infant groups, community groups and, more recently, publicity and media These last two spheres, enabled by the development of the technological means of communication, contributed to the dissemination of the set of consume ideas and for the emergence of the cultural industry, characteristic of the capitalistic production way in its present configuration. They develop new possibilities of perception of the world, in which the limits between childhood and adulthood are not anymore the same that have been established in previous centuries. So, the child musical appreciation is constituted by homogeneity regarding the senses built and disseminated by cultural industry and by the logical merchandizing, and singularities, associated to the construction of senses in interaction with global, local, and multiple contexts, through which the subject circulates and constitutes himself polyphonically

The intention of the present study was to analyze the adequacy of the playground of elementary schools, according to the point of view of the child student, direct user of this type of environment, what estimated its critical in respect to these spaces and aimed at to contribute for its improvement. Many studies have analyzed the quality of the physical environment available for activities of leisure in specific places for children, focusing in the influence of the physical space in the interpersonal relationships and the comfort and satisfaction generated by the physical characteristics of these spaces. Concern with scholar environment, specially the interest on playgrounds, has been subject of recent studies; however, little attention has been given to the opinion of the user-child in relation to this school environment. In this inquiry of the playground of two state schools of 1ª to 4ª series of elementary school in the city of Piracicaba, SP, was used: assystematics observations, photographic register of the studied environments, interviews with child-users and behavioral mapping. The main subjects resulting from the analysis of the interviews content were: adaptation, density and interpersonal relationships, and infantile confinement. The results revealed the unsatisfactory conditions of the courtyards, in respect to person-environment relationship. The children demonstrated to be critical, creative and responsible when answering questions related to the quality of the school courtyard. This finding confirms previous studies and leads to the conclusion that the child, as the direct user, should be included as an excellent source of consultation in the planning of the constructed environment

Reconhecendo a exposição a riscos à saúde a que adolescentes obesos estão submetidos e a necessidade da produção de estudos, os quais relacionem excesso de peso corporal e capacidade física durante a puberdade, configura-se como objetivo da presente comunicação explorar as relações entre o sobrepeso e a aptidão física dos alunos de ensino fundamental e médio de escola particular paulista. Trata-se de estudo de coorte, considerando como variável independente o índice de massa corporal (IMC) e como dependentes a resistência muscular localizada (RML) abdominal, força de membros inferiores (MMII), flexibilidade e agilidade. Os dados de interesse foram colhidos em duas oportunidades (no início de dois anos letivos subseqüentes), segundo testes específicos. Foi realizada análise multivariada dos perfis médios, complementada com a construção dos intervalos de confiança simultâneos, ao nível de 5% de significância. Constatou-se prevalência de 21,42% de sobrepeso e associação deste com: i) em meninos, menores RML abdominal e força de MMII e não evolução nas médias de agilidade; ii) em meninas, menor RML abdominal e agilidade, no início do período considerado. Ao se compararem os resultados entre os dois momentos de avaliação, notou-se que: i) a agilidade, das meninas com peso corporal adequado diminuiu significantemente; ii) a RML abdominal, mesmo do grupo masculino com sobrepeso, aumentou; e iii) a agilidade, somente em meninos com IMC inferior, melhorou. Verificaram-se, também entre o sexo masculino, médias de RML abdominal, força de MMII e agilidade significantemente maiores que as do grupo feminino. Nesse sentido, revela-se que a prescrição da atividade física para adolescentes deve realmente ser específica segundo composição corporal e sexo.

INTRODUCTION. Cardiovascular diseases (CVD) are the main cause of death in Brazil.OBJECTIVE. To evaluate the frequency of CVD risk factors In a population attending a health education community event.METHODS. Retrospective study that included 428 completed forms with clinical and demographic information of volunteers attending a public event, in May, 2006. Data were expressed by means and standard deviation or proportions and compared by Student's t test or Chi-square test. Associations between Arterial Hypertension (AH), Diabetes Mellitus (DM) and clinical variables were analyzed by multinomial logistic regression. Significance level was p<0.05.RESULTS. Mean age was 57 +/- 14years, and women represented 58% of the total population. The main cardiovascular risk factors were AH (39.5%), DM (15.4%) and dyslipidemia (25.89%). The frequency of unawareness about these risk factors was respectively 8.4%, 17.5% and 33.1%.. Family history of CVD was reported by 41% while only 67% reported having any information about DM or dyslipidemia. Among obese individuals (IMC >= 30 Kg/m2, 27.3% of the population), systolic blood pressure (133 +/- 16mmHg), diastolic blood pressure (84 +/- 11.5mmHg) and casual glycemia (124 +/- 52.5mg/dl) were higher when compared to non-obese (p<0.05). There was a significant association between obesity and dyslipidemia (p=0.04). Age and IMC were independently associated with AH and DM.CONCLUSION. The high frequency of modifiable cardiovascular risk factors in this population suggests the need for educational programs to promote primary prevention, mainly for the elderly and overweight.

The present study has the objective to analyze with teachers from Elementary School the knowledge mobilized in the organization of the teaching-learning process, and its implications in the exploitation of that process. The investigation was developed with two teachers from the first years of the Elementary School, from a public school in Pau dos Ferros-RN. It adopts as basis the notion of knowledge as a set of individual and social relations that the individuals maintain with the world and with themselves, in the teaching and learning relation. (CHARLOT, 2000). It considers yet that the knowledges are immediate processes, reconstructed and mobilized by the practice of reflection, in dialogical and interactional contexts in contact with others. (BAKHTIN, 2002, 2003; VYGOTSKY, 1991, 2004, 2005). The collaborative approach was the theoretical and methodological background that oriented the investigative-educative process. By choosing a collaborative research as basis of the investigative pathway, it starts from the knowledge that the critical and collaborative reflection developed with the teachers from the first years of the Elementary School contribute to explicitate and resignify the meanings assigned to the knowledges that these teachers mobilize in the organization of the teaching-learning and its implications in this process. The results of the reflexive and investigative process developed with the teachers demonstrate that the familiar, scholastic, academic, professional, and the work knowledges lived, constitute the consciousness of being a teacher, and that these knowledges implicate in the dynamics of the process of teaching-learning, but not always the teachers take consciousness about these knowledges. The critical and collaborative reflection, mediated by the actions of describing, announcing, facing and reconstructing allowed to the participants of the research to realize the knowledges of themselves and of the other, the difficulties and possibilities in the organization of the teaching-learning process

Éste trabajo se inserta en el ámbito de los cambios en la Enseñanza Fundamental (EF) brasileño que, por la Ley Federal n.º 11.114/2005 anticipa el EF para seis años de edad, y de la Ley n.º 11.274/2006 que amplia el mismo nivel de enseñanza de ocho para nueve años Tales cambios tienen sido respaldados por el argumento de la importancia de se anticipar y promover un mayor acceso a la educación y garantizar una permanencia bien sucedida del alumno en la etapa obligatoria de la Educación Básica. La inclusión de los niños de seis años en el EF puede ser considerada una conquista en el ámbito de las políticas públicas brasileñas destinadas a la educación de niños. Sin embargo, la sencilla simples anticipación/ampliación de matrículas en el EF puede constituirse en más una forma de exclusión, si no fueren garantizadas las condiciones necesarias para se ofrecer una educación de calidad que considere las peculiaridades de una práctica pedagógica de alfabetización con niños más jóvenes. Evidentemente, muchos son los factores que pueden influenciar la calidad de la educación y el tratamiento escolar financiamiento, gestión, organización del espacio escolar pero la acción del profesor, en ése sentido, es un factor primordial entre otros determinantes. Así pensando, definimos como objetivo de éste trabajo investigar saberes docentes requeridos de el profesor para el desarollo de una práctica pedagógica que tiene por meta la apropiación de la lengua escrita, por el niño de seis años recién-ingresa en la Enseñanza Fundamental respetando su condición de ser niño . Para tanto, en el ámbito del enfoque cualitativo de la encusta, realizamos un estudio de caso en dos instituciones públicas: Escola Municipal Professora Emilia Ramos y Centro Municipal de Educação Infantil Marise Paiva, ambas ubicadas en la Zona Este en la ciudad de Natal. De la análisis del contenido de los datos, emergió la temática Saberes Docentes para la Alfabetización de Niños de seis años en la Enseñanza Fundamental que, a la vez, cubre dos categorías de saberes, con suyas respectivas subcategorías: Saberes Docentes Transversales a las Práctica Pedagógica de Alfabetización y Saberes Docentes Específicos a la Práctica Pedagógica de Alfabetización. Entre tantos aprendizaje proporcionadas por el estudio, comprendemos que, sea en la Educação Infantil, sea en la Enseñanza Fundamental, el trabajo con el niño no debe constituirse en la negación de su infancia. Sin embargo, en se tratando de el EF, el esfuerzo para no desvirtuar la voluntad política de proporcionar al niño oportunidades de alfabetización debe ser redoblado, una vez que ésa etapa de la educación podrá ser la marca de un rico y agradable proceso de alfabetización, como puede ser motivo para que el niño se torne desinteresado y acobardado para aprender a leer y a escribir, si no fueren respetadas las necesidades y especificidades propias de ése momento de su desarollo. El estudio también ratificó nuestra comprensión de que la Alfabetización es un proceso peculiar, no constituyéndose, por lo tanto, en tarea simple para el docente, ni tampoco para el niño, visto que la lengua escrita, por si misma, ya es un objeto de estudio bastante complejo. Comprendemos, sin embargo, que esa complejidad no puede tornarse obstáculo para que, también en la escuela pública, ya a los seis años, se permita al niño un trabajo de calidad que tiene por meta su alfabetización, hasta porque, mientras participantes de una sociedad letrada, antes de ingresar a la escuela, los niños ya construyeran concepciones previas sobre la lectura y la escrita, a las cuales el profesor debe estar muy atento

A direção de enfermagem de um hospital universitário terciário da região Centro-Sul do Estado de São Paulo, visando a segurança do paciente e o estabelecimento de meio de comunicação entre equipe e direção, implementou em janeiro de 2004 o Boletim de Notificação de Eventos Adversos. O objetivo deste estudo foi analisar a utilização deste instrumento de comunicação e identificar: frequência, tipo, natureza e período dos incidentes/eventos adversos. Realizou-se análise descritiva dos dados de 826 boletins elaborados no período de janeiro/2004 a junho/2006. Verificou-se adesão à utilização do instrumento. Predominaram notificações de ocorrências assistenciais, embora notificações administrativas tenham apresentado número crescente de registros. Eventos adversos mais frequentes relacionaram-se à medicação, quedas, cateteres, sondas/drenos e integridade da pele. A praticidade do instrumento viabilizou sua utilização também por auxiliares e técnicos de enfermagem. A análise sistematizada e acompanhamento dos eventos adversos associados aos recursos de comunicação mostraram-se fundamentais para a segurança do paciente.

Among several theorems which are taught in basic education some of them can be proved in the classroom and others do not, because the degree of difficulty of its formal proof. A classic example is the Fundamental Theorem of Algebra which is not proved, it is necessary higher-level knowledge in mathematics. In this paper, we justify the validity of this theorem intuitively using the software Geogebra. And, based on [2] we will present a clear formal proof of this theorem that is addressed to school teachers and undergraduate students in mathematics

OBJETIVO: avaliar a qualidade de vida (QV) de mulheres na pós-menopausa usuárias e São Paulo. MÉTODOS: foi conduzido estudo clínico transversal, com 250 mulheres na pós-menopausa, idade entre 45 a 70 anos, atendidas em uma Unidade Básica de Saúde (UBS), de setembro de 2007 a agosto de 2008. As participantes foram divididas em dois grupos: usuárias de terapia hormonal (TH, n=70) e não usuárias (n=180). Consideraram-se como usuárias de TH aquelas que faziam uso contínuo dessa terapia há pelo menos seis meses. Foram avaliadas as características sociodemográficas e clínicas. Aplicou-se o Índice Menopausal de Blatt e Kupperman (IMBK), para avaliar a intensidade dos sintomas climatéricos, e o Questionário de Saúde da Mulher (QSM), para a avaliação da QV. A análise estatística foi realizada pelo teste do χ2 ou exato de Fisher, teste de Mann-Whitney e de Kruskal-Wallis. RESULTADOS: não foram encontradas diferenças significativas na comparação entre os grupos quanto à idade, menarca, menopausa, paridade e índice massa corpórea. Observou-se que 67,2% eram casadas, 83,2% com ensino fundamental e 53,2% se ocupavam com os trabalhos domésticos, não diferindo entre os grupos. As usuárias de TH relataram menor frequência de sintomas climatéricos (IMBK) de intensidade moderada e acentuada, comparadas a não usuárias (p<0,001). Na avaliação do QSM, verificou-se, entre as usuárias de TH, menor escore médio quanto ao déficit cognitivo (p<0,001), sintomas vasomotores (p=0,04), problemas com o sono (p<0,001) e atratividade (p=0,02), contudo, sem diferença no escore total quando comparadas a não usuárias. CONCLUSÕES: as mulheres na pós-menopausa usuárias e não usuárias de TH, atendidas em UBS, não apresentaram diferenças na QV global.

OBJETIVO: Foi realizado um estudo transversal, por amostragem de escolares, frequentadores das escolas estaduais de Bauru, São Paulo, com o objetivo de detectar possíveis portadores de tracoma. MÉTODOS: Foram examinadas 1.749 crianças do ensino fundamental, de 6 a 14 anos, durante o ano de 2005. As escolas foram escolhidas por sorteio, de acordo com o número de estudantes e com a localização da escola dentro do setor da cidade (centro, região intermediária e periferia). O diagnóstico dos casos foi clínico, seguindo as normas da Organização Mundial de Saúde (OMS), confirmado laboratorialmente pelo método da imunofluorescência direta para detecção de Chlamydia trachomatis. RESULTADOS: A prevalência de tracoma inflamatório foi de 3,8%, tendo sido diagnosticado tracoma folicular em 3,7% e tracoma intenso em 0,06% das crianças examinadas. As crianças com tracoma moravam principalmente na região intermediária e periférica da cidade, áreas onde o fornecimento de água pode ser descontínuo e o tratamento do esgoto pode estar ausente. Um programa de controle foi desenvolvido e os comunicantes foram diagnosticados e tratados. CONCLUSÃO: A prevalência de tracoma inflamatório em Bauru - Estado de São Paulo - é de 3,8%. Além da oportunidade de reconhecer e tratar os portadores e contatantes, os autores realçam o fato positivo da mobilização da comunidade bauruense no sentido de prevenir a cegueira pelo tracoma.

Purpose: To determine the frequency of glaucoma and evaluate the behavior of 24-hour intraocular pressure in patients with the obstructive sleep apnea syndrome (OSAS). Methods: Eleven consecutive patients with OSAS, diagnosed by polysonography, were avaliated in a cross-sectional study. Demographic data were analyzed: age, sex, race/color, weight, height and associated diseases. The patients were submitted to complete ophthalmologic examination, including the visual field, as well as to 24-hour intra-ocular pressure (IOP) evaluation by an applanation tonometer at 9h, 12h, 15h, 18h, 24h and 6h in the lying and sitting positions. The diagnostic criterion for glaucoma was alteration of the visual field (VF) compatible with glaucoma and one or more of the following alterations: cup-disc ratio >= 0.7, hemorrhage, wedge-shaped defect, bayonet-shaped vessels, Hoyt's sign, asymmetry > than 0.2 between cup/disc ratio of the eyes. The angle should be opened without alterations. Results: 9 (82%) of 11 patients showed glaucoma or were suspected to have glaucoma, 9% of which exhibited normal tension glaucoma and 73% were suspected to have glaucoma for presenting alterations in the optic nerve or ocular hypertension. The mean for the IOP values of the 11 patients was observed to be the highest at 6 o'clock, when they were lying down. Variations of IOP >= 5 mmHg occurred in 7 (64%) of the patients, and variations of up to 14 mmHg and IOP peaks of up to 32 mmHg were observed. Conclusion: OSAS may be an important risk factor for the development of glaucoma, particularly that of normal tension glaucoma. Patients with OSAS must be referred to an ophthalmologist and those professionals must be attentive to the association of sleep disorders in patients with open-angle glaucoma.

The first experimental data suggesting that neoplasm development in animals might be influenced by infectious agents were published in the early 1900s. However, conclusive evidence that DNA viruses play a role in the pathogenesis of some human cancers only emerged in the 1950s, when Epstein-Barr virus (EBV) was discovered within Burkitt lymphoma cells. Besides EBV, other DNA viruses consistently associated with human cancers are the hepatitis B virus (HBV), human papillomavirus (HPV), and Kaposi sarcoma herpesvirus (KSHV). Although each virus has unique features, it is becoming clearer that all these oncogenic agents target multiple cellular pathways to support malignant transformation and tumor development.
