Schilder(1980) defines body image as the figuration of the body in your mind,ie to the way the body is presented to all. This image is constructed from six months in the infant´s contact with his mother by touch,thought the reflection of his image in the mirror and then in the contexto f activies préschool- didatic educator pedagogical proposes by consolidating the six years age. This importance of stdying the construction of body image pré-school educator is to prevent a failure in the process causing the child to change that image generating blocks and physical or psychological dificulties in the socialization process of children by promoting distortion of body image . O study objective is to understand how such package is the process of building up this image in preschool and your contribution to the process of learning of child. A methodology was a research review on amaig body, enconpassing the overall development of child and adult disorders the failure of the process constructive in this picture and a brief educational propose of how early childhood educator can work with this theme in pré-school. This study concluded that this topic is important to be working in the Field of education encompasses a degree in Physical Education and Pedagogy words.

Nowadays the mammography is the most effective way of revealing early breast cancer. The image in this kind of exam is gotten trough a x-ray sheaf of low energy, however, the suitable visualization of the interesting structures by the radiologist is not always possible due several factors that appears since the mamma composition until the equipments limitation. The regulation 453/98 sets quality control tests and limits of acceptation that guarantee a good development of the mammographys. The purpose of this study is the 3D principle ( Diagnostic, Dose and Dollar), that means, an improved diagnosis, a dose reduction in the patient and a cost decrease for the Institution. In this study was made the quality control tests set by the Regulation in two mammography equipments from Hospital das Clínicas da Faculdade de Medicina de Botucatu (HCFMB - UNESP). The results reached in this research were used in the renovation process of quality stamp in mammography granted by Colégio Brasileiro de Radiologia (CBR) to the diagnosis by image from the HCFMB – UNESP

The comet assay is a method of DNA damage analysis widely used to quantify oxidative damage, crosslinks of DNA, apoptosis and genotoxicity of chemicals substances as chemical, pharmaceuticals, agrochemicals products, among others. This technique is suitable to detect DNA strand breaks, alkali-labile sites and incomplete excision repair sites and is based on the migration of DNA fragments by microeletroforesis, DNA migrates for the anode forming a “tail”, and the formed image has the appearance of a comet. The slides can be stained with fluorescence or silver, having differences in the microscopy type used for the analysis and the possibility of storage of the slides, moreover, the first one is a stained-method with more difficulties of accomplishment. The image analysis can be performed by a visual way, however, there is a disadvantage as the subjectivity on the results, that can be minimized by an automated method of digital analysis. This process was studied in this report with the aim to perceive the validation of the digital analysis turning it a quantitative method with larger reproductibility, minimizing the variability and imprecision due to the subjective analysis. For this validation we selected 50 comets photographed in a standardized way and printed, afterwards, pictures were submitted to three experienced appraisers, who quantified them manually. Later, the images were processed by free software ImageJ 1.38x, printed and quantified manually by the same appraisers. The intraclass correlation was higher to comet measures after image processing. Following, an algorithm of automated digital analysis from the measures of the comet was developed; the values obtained were compared with those 12 estimated manually after the processing resulting high correlation among the measures. The use of image analysis systems increases ...(Complete abstract click electronic access below)

The signal-to-noise ratio and image uniformity analysis parameters are very important in quality control of an MRI scanner. They are measured in regular tests with phantoms. In these tests, however, used to quadrature coil, which has been most widely used clinically, and, therefore, was replaced in the procedures for body coil. In order to understand the difference between these two parameters in these coils, the study aimed to analyze the images acquired from four different phantoms in the same equipment under the same conditions for comparison purposes. With these results, it can be concluded that the body coil signal-to-noise ratio has always smaller than the quadrature in any projection, whereas the image uniformity is larger

The objective of this paper is to discuss the construction of the image of São Paulo state public schools teachers in the public sphere, by the media and the trade union press, and see how that image is formed in both of them, without making any comparisons, from the covering of 2010 strikes by newspapers Folha de S. Paulo and Jornal da Apeoesp. This paper uses as theoretical basis the study of Media Hegemony, the concept of Radical Media and Public Sphere, as well as the relationship between them and social movements. It also considers the observation of the history and characteristics of trade union press and the Standards of Manipulation by the Press, proposed by Perseu Abramo. The chosen method was the identification, selection and organization of stories about education published by Folha de S. Paulo during the period; the application of Abramo’s proposed manipulation standards on the stories about the strike; research, selection and observation of print publications (Jornal da Apeoesp and newsletters Apeoesp Urgente) about the strike, published by Apeoesp during the same period

Complementary and alternative medicine (CAM) is becoming increasingly popular, and despite of the growing demand for these practices, physicians and CAM-providers work separately and there is no sufficient effort in the promotion of an integrative health care. Questions like differences of concepts and language, lack of scientific evidence through randomized clinical trials, no regulation of CAM-providers, products and services, besides the lack of government policies in this scope, turn the process of integration difficult and threaten the quality of delivery of health care. Through the integrative review method, the purpose of this paper is to discuss the issues involved in the integration process of complementary and alternative medicine into the conventional health care systems (guided by principles of biomedicine), addressing benefits and risks, obstacles to integration and models of integration in the discussion topicsl

Imagem corporal é um construto multifacetado que une desde a percepção até as atitudes das pessoas sobre seu próprio corpo e compreende o conceito que cada pessoa tem de seu corpo e a sua representação mental. A deficiência física e a construção negativa da imagem corporal pode fazer com que o auto-conceito do indivíduo também fique negativo, ampliando valores estigmatizantes, preconceituosos e que reforçam sentimentos de inferioridade, baixa auto-estima, exclusão social e depressão. A prática regular de exercício físico além de propiciar a reabilitação oferece benefícios para a saúde com vantagens fisiológicas (e.g. prevenção e redução de efeitos de doenças como diabetes, hipertensão, cardiopatia e osteoporose) e vantagens psico-sociais (e.g. redução de estresse, melhora na auto-estima e imagem corporal). A imagem corporal freqüentemente está associada com atitudes alimentares uma vez que distorções na imagem podem ser sintomas de distúrbios alimentares. O presente estudo teve o objetivo de verificar se distúrbios alimentares e alterações na imagem corporal tem relação com a prática esportiva por pessoas com deficiência física. Foram avaliados 22 atletas praticantes de basquete sobre rodas (32 ± 9 anos) e 22 deficientes físicos não atletas (35 ± 11 anos). A avaliação de atitudes alimentares foi realizada pelo Teste de Atitudes Alimentares (EAT 26 - Eating Attitude Test. Garner e Garfinkel, 1979) e avaliação da imagem corporal foi realizada pelo Questionário de Imagem Corporal (BSQ – Body Shape Questionnaire. Cooper et al, 1987) e pelo Questionário sobre Deficiência Física e Estima Corporal (PDBEQ – George Taleporos et al, 2002). Os resultados apontaram menor distúrbio da imagem corporal, porém com ausência de problemas alimentares para os participantes atletas praticantes de basquete...

A presente monografia tem a finalidade de refletir como a imagem poética é construída na poesia concreta de Augusto de Campos. Para isso, será utilizada a teoria de alguns estudiosos, como Alfredo Bosi, Octavio Paz, Philadelpho Menezes, Aguillar, entre outros, para embasar a reflexão sobre a imagem poética que se desenha a partir da leitura da poesia por meio das palavras que compõem a produção artística. Há uma ênfase, durante a análise das poesias, nas palavras que as constituem, pois elas formam um elemento fundamental para a criação da imagem poética na produção da poesia concretista. O trabalho também reflete sobre a repercussão do movimento Concretista em décadas distintas (50,70 e 90) e em diferentes vertentes, como na música, nos âmbitos nacional e internacional, ressaltando a importância do Concretista para o enriquecimento da poesia, especialmente as compostas por Augusto de Campos. Também será mencionada a diferença entre a poesia visual e a poesia concreta. Para isso, serão explicitadas as suas peculiaridades e as suas propostas

The Nuclear Medicine is a medical specialty which uses different radioisotopes for diagnostic and therapeutic purposes. The isotopes are radioactive elements which are administered in vivo and present distribution to specific organs or cell types. The knowledge of radioactivity and notions related to ionizing radiation allow to contextualize the radiological protection measures to be taken in Nuclear Medicine. So it is possible to minimize unnecessary exposure to patients, the public, and individuals occupationally exposed and the environmental. For this it is necessary to relate the physical and technological bases apply to this mode with the standards established by regulatory agencies, including the CNEN (National Nuclear Energy Commission) and ANVISA (National Agency for Sanitary Vigilance). In this scenario, it is important that the theoretical endorse the activities which are periodically audited for verification of compliance with the standards that aim to radioprotection. One role of the Medical Physicist in these services is, therefore, act as Radiation Protection Supervisor exerting numerous activities and ensuring compliance with these standards. In this context the stage in the area of Nuclear Medicine was developed in many customers of the enterprise Rad Dimenstein & Associados LTDA, among them the hospitals Israelita Albert Einstein (HIAE), Nossa Senhora de Lourdes (HNSL), Santa Paula (HSP), Cruz Azul (CRAZ), Grupo Fleury, among other clinics. Following the routine and then carrying out various activities pertaining to the Medical Physicist in the area, it was noted that the measures and actions are extremely effective and fundamental in terms of radiological protection

Introdução: Até o presente momento, nenhum estudo analisou a relação entre imagem corporal (IC) e dança em adultos jovens e adultos idosos. Dados dessa natureza podem auxiliar no entendimento da influência da dança na imagem corporal, bem como evidenciar seus benefícios em diferentes populações. Objetivo: Investigar a IC de adultos jovens e adultos idosos praticantes de dança. Método: Participaram deste estudo 10 adultos jovens e 10 adultos idosos do gênero feminino praticantes regulares de diversas modalidades de dança que responderam, voluntariamente, à versão brasileira do Body Shape Questionnaire (BSQ) adaptado pela autora para a dança e à Escala de Silhuetas para Adultos (ES) e foram questionados sobre seu peso e estatura para cálculo do Índice de Massa Corporal (IMC). O grupo controle foi composto por 10 adultas jovens e 10 idosas fisicamente ativas que responderam à versão brasileira do BSQ (sem adaptação) e à Escala de Silhuetas e também foram questionados sobre seu peso e estatura. Na análise estatística final, para a comparação entre os grupos foi utilizado o Mann-Whitney Test. Resultados: No instrumento BSQ, para as variáveis idade e dança, o Mann- Whitney Test não apontou diferença significativa (p≤0,05). No instrumento ES, para as variáveis idade e dança, o Mann-Whitney Test também não apontou diferença significativa (p≤0,05). Conclusão: Tanto a atividade física quanto a dança apresentaram ser um bom instrumento para melhora da IC. Entretanto, considera-se de extrema relevância a realização de mais pesquisas nesta área. Uma amostra maior também poderia confirmar os dados já encontrados neste estudo e na literatura, em termos de significância estatística

The SPECT (Single Photon Emission Computed Tomography) systems are part of a medical image acquisition technology which has been outstanding, because the resultant images are functional images complementary to those that give anatomic information, such as X-Ray CT, presenting a high diagnostic value. These equipments acquire, in a non-invasive way, images from the interior of the human body through tomographic mapping of radioactive material administered to the patient. The SPECT systems are based on the Gamma Camera detection system, and one of them being set on a rotational gantry is enough to obtain the necessary data for a tomographic image. The images obtained from the SPECT system consist in a group of flat images that describe the radioactive distribution on the patient. The trans-axial cuts are obtained from the tomographic reconstruction techniques. There are analytic and iterative methods to obtain the tomographic reconstruction. The analytic methods are based on the Fourier Cut Theorem (FCT), while the iterative methods search for numeric solutions to solve the equations from the projections. Within the analytic methods, the filtered backprojection (FBP) method maybe is the simplest of all the tomographic reconstruction techniques. This paper's goal is to present the operation of the SPECT system, the Gamma Camera detection system, some tomographic reconstruction techniques and the requisites for the implementation of this system in a Nuclear Medicine service

This project aims the verification of doses in canines and felines to chest and coxal exams due to the transition from screen-film to computed radiography system. It also seeks a possible optimization of the new techniques employed in this new system. The study was carried out in Diagnostic Imaging service in Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia da Universidade de São Paulo using a conventional x-ray equipment. Initially, data about the physical characteristics of animals and the technique currently used in computed radiography was collected for each of 80 chest and 16 coxal X-ray examinations. The animals were divided into different groups according to the body weight. For each group, were calculated the averages of each item: thickness of the region to be imaged, voltage, current, exposure time, current-time product, size of film used, presence or absence of bucky and focus (small or large). The techniques have been reproduced in phantoms (representative of the thickness of the animal) in order to collect the air kerma entrance. Based on the average of intermediate size M group (weights less than 5 kg for cats and from 10.1 kg and 20 kg for dogs) analysis of image quality using three devices test patterns were made consisting of the evaluation of spatial resolution, low-contrast resolution and contrast-detail. In general, the results showed the dose animals decreased with the use of computed radiography and was possible to preliminary optimization of some techniques used currently in CR
