AVALIAÇÃO DA COMPRESSÃO DA IMAGEM DIGITAL DA TELERRADIOGRAFIA LATERAL NA REPRODUTIBILIDADE DA MARCAÇÃO DE PONTOS CEFALOMÉTRICOS

A imagem digital adquirida pelo sistema da placa de fósforo foto ativada é visualizada no monitor do computador em um formato denominado DICOM. Este formato ocupa muito espaço para armazenamento, o que dificulta o arquivamento e transmissão da imagem pela Internet. O objetivo deste estudo foi avaliar a influência da compressão JPEG, nos Fatores de Qualidade 100, 80 e 60 na reprodutibilidade da marcação de pontos cefalométricos em imagens de telerradiografias em norma lateral comparadas com o formato DICOM. A amostra consistiu de 120 imagens de telerradiografias em norma lateral obtidas a partir de 30 indivíduos, dos quais se obteve uma radiografia digital no formato DICOM. Essas imagens foram convertidas para o formato JPEG. Após o cegamento e randomização da amostra, três Ortodontistas calibrados marcaram a localização de 12 pontos cefalométricos em cada imagem utilizando o sistema de coordenadas X e Y. Esse procedimento foi repetido após 1 mês. A reprodutibilidade intra e inter observador foi calculada usando o teste de correlação intraclasse. Para comparação entre os grupos de compressão e DICOM na reprodutibilidade de marcação dos pontos utilizou se a Análise de Variância (ANOVA) a um critério para medidas repetidas. Os resultados mostraram que as marcações dos pontos cefalométricos foram bastante reprodutíveis, exceto para o ponto Órbita na coordenada X. Os diferentes formatos de arquivo mostraram estatisticamente iguais para cada ponto e eixo aferido. As compressões JPEG estudadas das imagens de telerradiografias em norma lateral não tiveram efeito na reprodutibilidade da marcação dos pontos cefalométricos testados.

ESTUDO COMPARATIVO DO RECONHECIMENTO E DA MENSURAÇÃO DOS ATIVOS FIXOS TANGÍVEIS NO POCAL E NO SNC-AP

Perante a atual reforma da Contabilidade Pública em Portugal, foi aprovado, em setembro de 2015, o novo Sistema de Normalização Contabilística para as Administrações Públicas (SNC-AP). Este trabalho tem por objetivos analisar o definido no POCAL e no SNC-AP quanto ao reconhecimento e à mensuração dos ativos fixos tangíveis (AFT). Este estudo permite concluir que o novo normativo evidencia um avanço face ao POCAL, definindo não só o conceito de ativo e de AFT, como também os critérios de reconhecimento que um elemento deve cumprir para que possa ser reconhecido como tal, permitindo assim uma maior consistência no reconhecimento destes elementos, por parte das diferentes entidades públicas. Por outro lado, no que respeita à mensuração, o SNC-AP segue de perto, com as devidas adaptações, os normativos internacionais, introduzindo dois momentos de mensuração dos AFT, e referindo o justo valor explicitamente enquanto critério de mensuração aplicável a situações concretas.

Animação em contexto de realidade aumentada: Imagem animada como mediador entre utilizador e espaço

A animação é uma área disciplinar com raízes tradicionalmente sustentadas nos media audiovisuais, mas que tem evoluído para outros contextos e suportes em novos media digitais. Uma das áreas na qual essa evolução é visível, é no contexto da realidade aumentada. Este documento descreve o desenvolvimento de um protótipo de animação interativa tridimensional para ser visionado através de realidade aumentada, e para ser implementado na Sala VIP da Casa da Música, no Porto. O protótipo permite, através de interação com personagens virtuais, obter informação específica sobre o espaço e os seus conteúdos. Simultaneamente o utilizador pode interagir de um modo lúdico com as personagens animadas na interface. Foram investigadas características da animação para uma plataforma móvel através de interfaces em realidade aumentada bem como as suas vantagens tecnológicas, e possíveis restrições do hardware e software na aplicação desenvolvida.

Humanização do direito e da justiça: reconhecimento e efetividade dos direitos da criança e do adolescente

The crisis of the model of technical and formal rationality is discussed in light of a paradigmatic change of the Law that arises in the context of recent transformations of capitalism worldwide, proposing a humanization of Law and Justice with a new ethical-political foundation that promotes a reconciliation between the rules that governs the social order and the world of life, a process of society’s emancipation. As empirical cut it is taken the Right of Children and Youth and, in a practical perspective, the recognition and effectiveness of the Rights of Children and Adolescents in Brazil. It is proposed to analyze the process of democratization and legitimacy of the children and youth rights from the study and apprehension of knowledge that advocate a multidisciplinary view of knowledge and a dialogic praxis for construction of a thought able to contribute to the analysis of public policies and to develop strategies that allow a real change on the social thinking about the doctrine of integral protection of children and adolescents. The proposed methodological approach was developed from a dialectical view of science and as a research strategy for data collection of symbolic cartography or cartographic sociology of law and justice. It is shown that in the process of humanization of the Law and Justice there is a gap between the rights and the democratic participation of these rights.

As inter-ações entre espaço do corpo e o movimento dançado

This dissertation seeks to reflect about the relations between danced movement and body space (Kinesphere), and their contributions to the expansion of the expressive possibilities of the subject on dancing. According to Rudolf Laban there is no space that is empty, because it is always being modified and signified at every moment by the movement. Space exists because we interact with it, at the same time movement occours configuring a signifcant space that is incessantly transformed. In this sense, space, body and movement appear in this research as interconnected and interdependent. For this discussion we have as main interlocutor the studies of Rudolf Laban. The nature of this research is qualitative and descriptive. This is a context that embraces the phenomenon of dance and as such it is based on a dimension that doesn't deal with mensurability, but with the art scene, fruitful in its infinite openness to the creation of multiple significances for what has been lived. We also propose to present a report about the practical study developed in the discipline Coreologia in the licentiate course of Dance in UFRN, as well as the analysis of the interviews applied to students of this curricular component. The questions were developed in a way that lead to a reflection about the experience of those interviewed in this discipline, thus generating material for us to discuss how the students perceive dance based on the relational study between space and movement. We realize that this study may favor an understanding of the relations that the experienced movement in the act of the dance weaves along the spatiality that receives and fills our bodies, resignifying the vision of a space which is restrict to the mere place were the body moves and occupies. It also favors the reflections concerning the body that moves and creates spatiality when dancing, thereby bringing to the Performing Arts a chance to think and to experience on the expansion of the expressive gesture in dance and beyond it, led by the recognition of the principles that organize human movement pointed by Laban. It also contributes on the formation of the students in licentiate courses of Dance by questioning the ways to appropriate the contents worked in a graduation discipline as regards to the availability of the body for dance. This dissertation is divided in three parts, called Impulsos. In the First Impulso: “Primeiros Gestos Textuais”, we find an introduction to concepts and ideas of body, movement and space that permeates all the work. In the Second Impulso: "Nós", the triad body-space-motion is discussed using the metaphorical image of a knot that binds these three concepts. The third and final Impulso: "Enlaces" deal with impressions and discoveries lived during the experimentation of the principles of inter-actions studied here, in the lessons of the already mentioned discipline

Os efeitos do reconhecimento da diversidade sexual como um direito humano pelo sistema interamericano de proteção

La diversidad sexual emerge en las Américas como una de las cuestiones más importantes en relación con la protección y promoción de los derechos humanos. A partir de la democratización de la mayor parte de los Estados Sudamericanos en los años 80, se ha iniciado una discusión acerca de la ampliación del concepto de igualdad con el fin de introducir el derecho a la diferencia como otra expresión de la dignidad de la persona humana, cuyos estudios fueron encabezado de lo que se llamaba La hermenéutica de la Diversidad. En este escenario, el Derecho Internacional de los Derechos Humanos aparece como el principal responsable por el proceso de reconocimiento de la diversidad sexual como un derecho humano, lo que permite la asignación de temas tales como la sexualidad y el género en la agenda de los principales órganos regionales de protección de derechos humanos, así como en la agenda de algunos Estados, que por su promoción de políticas de diversidad han llegado a ser considerados empresarios normativos en relación con el libre ejercicio de la sexualidad humana. En este sentido, se pretende con esta tesis analizar el proceso de reconocimiento de la diversidad sexual como un derecho humano en el marco del sistema interamericano de protección, comprobando el potencial normativo de Argentina, Brasil y Uruguay con respecto a la adopción de normas internas promoción de la diversidad sexual. También tenemos la intención de analizar la norma internacional llamada Convención Interamericana contra todas las formas de discriminación e intolerancia como el primer tratado producido por el sistema interamericano para la protección de la sexualidad como un derecho digno de protección. La investigación ha demostrado que después de la posición adoptada por la Comisión y la Corte Interamericana respecto al ejercicio de la sexualidad, países como Argentina, Brasil y Uruguay promovieron un progreso significativo en el campo de las libertades individuales y en el campo de las políticas públicas de asignación de la sexualidad como un derecho que necesita de una protección efectiva del Estado

Pistas visuais no reconhecimento intra e interespecífico em duas borboletas miméticas impalatáveis

Duas espécies de borboletas miméticas Heliconius erato e Heliconius melpomene apresentam coloração similar. Tal similaridade pode atuar confundindo o reconhecimento de seus co-específicos no momento da escolha de parceiros sexuais. As duas espécies possuem um conjunto de variações sutis na cor de suas asas que são compartilhadas por ambas espécies, como os pontos vermelhos encontrados acima da faixa amarela. Em H. erato variações na cor de suas asas são exclusivas da espécie como os red raylets e pontos amarelos na região distal da asa posterior. Acredita-se que tais variações fenotípicas auxiliem no reconhecimento de seus co-específicos, para tanto, o presente estudo tem por intuito verificar se as duas espécies envolvidas na análise reconhecem seus co-específicos. Experimentos com modelos que contemplaram variações sutis foram montados e apresentados aos machos de H. erato e H. melpomene. Em cada experimento foi verificado a probabilidade relativa de aproximação do macho ao modelo. O teste de likelihood indicou que as diferenças sutis encontradas nos padrões de asas de H. erato e H. melpomene podem atuar como pistas de reconhecimento de indivíduos da mesma espécie. Sendo que a espécie H. erato pode ser considerada um discriminador mais refinado no reconhecimento, e ambas as espécies selecionaram modelos que possuem variações médias, indicando seleção normalizadora para a escolha do padrão de asa. Podemos concluir, que a cor e, principalmente, os padrões sutis na variação da cor são utilizados como um sinal usado por borboletas no reconhecimento de seus co-específicos.

O que ser quer imagem, o que se quer desejo?: entre o fabular de desejos e as construções imagéticas na prosa de Fiama Hasse Pais Brandão

Este trabajo presentado, direccionado a la defensa de la disertación de maestría, intitulada ¿Lo que se quiere imagen, lo que se quiere deseo?: Entre el fabular de deseos y las construcciones imagéticas en la prosa de Fiama Hasse Pais Brandão, discute hasta donde el deseo impulse la imagen y hasta donde esta imagen es tocada por este deseo, visualizando dentro de un sistema literario poético y singular, las construcciones de la imagen junto a las fabulaciones de deseos, lo que nos expone delante de procesos de semiotización por medio de la escrita, de subjetivación, de vértigo, de sensibilización para los efectos y deseos en cuanto producción de sentido y multiplicidades estéticas en cuya letra transgresiva se aventura. En este sentido, el análisis transitará entre el discurso erótico y los problemas fundamentales que este pode, bien como el proceso de construcción de imagen, recortado por vía de discursos problematizados por el lenguaje presentado por la autora Fiama Hasse Pais Brandão. Para tanto, colocase como escopo una investigación norteada por autores como Bataille, Roland Barthes, Luiz Roberto Monzani, Suely Rolnik, Walter Benjamin, Georges Didi-Huberman, Maurice Blanchot, Félix Guattari, Gilles Deleuze, dentre otros que puedan transitar por las relaciones, en este estudio, establecidas, constituyendo el corpus teórico y de discusión, atendiendo al caráter cualitativo implicito en el desarrollo de esta disertación. Cuanto al corpus literario, este es compuesto por los contos trídos en Cuentos de la imagen (2005), de manera a constituiren cuerpo-subjetividad, envolviendo ideas, afectos, perceptos y imagens.

Ser-imagem – Além do selfie. A autorrepresentação fotográfica no Facebook

In a crescent connected and image-made society in various online social networks, each user taking pictures of him/herself and posting them on social online network, makes a self-registration that emerges in self-representation by aggregated daily practices of various themes. This research aims to study the dynamics of the relations of this photographic self-representation relations with agency, technology, affectivity, and consumption that goes beyond narcissism, composing a being integrated with the visual power and its reverberations, which I hereby call as Being -Image. The goal of this paper is an anthropological look over these practices. In this sense, I carry out the research developed in the field of image and cyber antropology with various interlocutors established in dialogues, analysis and virtual meetings. I tried, besides conversations and interviews, to analyze the profiles on the social network as well as daily posts, photo albums available on online network , sharings and mainly selfies.

Estabelecimento, reconhecimento e defesa territorial em Stegastes fuscus

Os estudos da territorialidade e de comportamentos associados a ela favorecem o entendimento da maneira como as interações ecológicas afetam a composição de espécies e a dinâmica de uma comunidade. No presente estudo tivemos como objetivo geral investigar o comportamento de Stegastes fuscus, um peixe-donzela territorialista, em ambiente natural e em cativeiro, com foco na capacidade de localização territorial, reconhecimento e defesa de uma área estabelecida. Para tanto subdividimos o trabalho em 3 capítulos. O primeiro teve como foco o estudo da espécie em ambiente natural objetivando estimar a área do território ocupado e os padrões comportamentais da por ela expressos. Sendo encontrado que a área média ocupada por S. fuscus foi de 274 cm2 e os comportamentos mais observados foram: vigilância, ingestão de alimento, tempo no abrigo/toca e displays agressivos. O segundo capítulo teve como alvo investigar a capacidade de localização espacial da espécie mediada por pistas visuais. Os resultados demonstraram que S. fuscus apresenta marcante aprendizagem condicionada e possibilidade de existência de orientação espacial na espécie. O terceiro capítulo teve como objetivo avaliar a influência da residência prévia estabelecida e do reconhecimento de coespecíficos nos resultados de confrontos agonísticos. Os resultados apontaram a residência como fator prioritário na dinâmica das disputas agonísticas e que aspectos relacionados à familiaridade como relevantes e destacam-se mais quando não existe um território previamente estabelecido. Diante disso nossos resultados podem favorecer o entendimento da dinâmica estrutural da comunidade na qual S. fuscus esta inserida, sendo isto significativo tendo em vista a importância ecológica da espécie para o ecossistema.

A TV como objeto de leitura da imagem no contexto escolar: uma pesquisa-ação com alunos do ensino médio

This research seeks to reflect on the dynamics of television reception, studying the Brazilian TV miniseries Hoje é Dia de Maria, produced by Globo Television Network, and aims to generally promote inferences in the process of image reading, mainly for aesthetic reading in school context, aiming at the formation of visual proficient readers. The research was conducted with students from the third grade of a state high school, geographically located in the city of Natal, Rio Grande do Norte. The theoretical framework comes from the assumptions of cognitive social interactionism to understand language, and it is also based on the ideas of Bakhtin (1992) and Vygotsky (1998), which enabled us to understand the social interaction and the Theory of Aesthetics Reception and Aesthetic Effect with Jauss (1979) and Iser (1999), which provided a better understanding of aesthetic experience, aesthetic effects and production of meaning. The methodological approach assumes a qualitative nature and an interpretive bias, accomplished through interviews, observation, questionnaire and application of a set of investigative activities, such as introductory exposition of themes, handing out of images and mediation process. This research is the result of a research-action process in a pedagogical intervention in a state school. The results indicate that the interactional linguistic resources used by the speakers demonstrated lack of prior knowledge and repertoire regarding image reading, which initially led them to do a cursory reading. It was evident that the respondents were unaware of the initial proposal. However, throughout the meetings, it was possible to realize their transformation, because the pre-established concepts were analyzed with the help of mediation, so that the group felt more autonomous and safe to read images at the end. The survey also showed significant data, so that the school could develop new methods of teaching televisual reading.

Correlação entre imagem corporal e autoestima em pessoas com ostomias intestinais

Ostomized is every individual that, because of a traumatic or clinical condition, it required a surgery resulting in the externalization of a hollow organ through the skin, and such temporary or permanent condition. This study has the general objective to investigate the relationship between body image and self-esteem in these individuals; as well as to verify their levels of satisfaction with their body image regarding the aspect of appearance and to evaluate the degree of self-esteem related to that condition. This is a correlational research, cross-sectional, which was accomplished in an institution in support of these users of Rio Grande do Norte state, with location in Natal. There were used three sampling instruments: a structured general questionnaire covering socio-demographic and clinical data; the Satisfaction Scale with Appearance (SSA) and the Rosenberg Self-Esteem Scale (RSS). The information obtained was analyzed with the aid of an electronic spreadsheet software. The project is according with the resolution 466/12 of the National Health Council, It was approved by the Research Ethics Committee of UFRN, under number CAAE 19159713.5.0000.5537 in August 2013. The sample consisted of 93 participants with an average age of 50.4 years (SD = 15.4). In general they had low satisfaction with their body image (M = 66.9), as regards the appearance, although maintained high levels of self-esteem (M = 34.8). Therefore, It was found a positive correlation, moderate (ρ = 0.426) and statistically significant was found (p <0.001) from the application of the Spearman correlation test. Therefore, dissatisfaction with body image is an important issue to be observed by professionals who attend ostomizeds. however, it seems, other aspects are also influencing the level of self-esteem of these individuals, who were not able to be determined in this study.

Avaliação da imagem corporal de mulheres submetidas à cirurgia oncológica mamária

Breast cancer is the second type of cancer that affects more women of reproductive age in Brazil. Surgical treatments include: conserving surgery or mastectomy. Aimed to evaluate body image of women undergoing breast cancer surgery, based on the scale Body Image After Breast Cancer Questionnaire. It is a descriptive, exploratory, transversal, with a quantitative approach. Data were collected in Norte-riograndense League Against Cancer, between the months from March to May 2015, after consideration of the Research Ethics Committee of that institution CAEE 35155714.1.0000.5293. The study population consisted of women undergoing breast onco-surgery. To calculate the sample considered the finite population, totaling 120 subjects, collected four guys the most. Data were analyzed by the software Statistical Package for Social Sciences version 20.0. The domain scores of the scale were evaluated using descriptive and inferential statistics. The surgical group mastectomy without reconstruction showed greater impairment of body image in the field "vulnerability", "Care for the body" and "transparency" in relation to other surgical types, and suggests susceptibility to cancer, body appearance and worry that disturb other. The Kruskal-Wallis test showed greater dissatisfaction with body image in the fields "body Stigma" and "transparency" to the radical neoplastic surgery over other surgical types. Dissatisfaction with body image and physical appearance was detected in this study in all six image fields present in scale, with emphasis on the "body Stigma" and "Transparency". This means that the body image disorder is formulated based on the perception of others about themselves and not by perception "self", which justifies the concern with appearance, with body and hide the consequences stemmed cancer. It is expected that the data obtained from the evaluation of body image presented in this study contribute to enable the assistance to oncocirurgiada woman breast integral, essential for the practice of Nursing.

Uma interface para o controle de robôs móveis por intermédio de gestos

The main objective of this work was to enable the recognition of human gestures through the development of a computer program. The program created captures the gestures executed by the user through a camera attached to the computer and sends it to the robot command referring to the gesture. They were interpreted in total ve gestures made by human hand. The software (developed in C ++) widely used the computer vision concepts and open source library OpenCV that directly impact the overall e ciency of the control of mobile robots. The computer vision concepts take into account the use of lters to smooth/blur the image noise reduction, color space to better suit the developer's desktop as well as useful information for manipulating digital images. The OpenCV library was essential in creating the project because it was possible to use various functions/procedures for complete control lters, image borders, image area, the geometric center of borders, exchange of color spaces, convex hull and convexity defect, plus all the necessary means for the characterization of imaged features. During the development of the software was the appearance of several problems, as false positives (noise), underperforming the insertion of various lters with sizes oversized masks, as well as problems arising from the choice of color space for processing human skin tones. However, after the development of seven versions of the control software, it was possible to minimize the occurrence of false positives due to a better use of lters combined with a well-dimensioned mask size (tested at run time) all associated with a programming logic that has been perfected over the construction of the seven versions. After all the development is managed software that met the established requirements. After the completion of the control software, it was observed that the overall e ectiveness of the various programs, highlighting in particular the V programs: 84.75 %, with VI: 93.00 % and VII with: 94.67 % showed that the nal program performed well in interpreting gestures, proving that it was possible the mobile robot control through human gestures without the need for external accessories to give it a better mobility and cost savings for maintain such a system. The great merit of the program was to assist capacity in demystifying the man set/machine therefore uses an easy and intuitive interface for control of mobile robots. Another important feature observed is that to control the mobile robot is not necessary to be close to the same, as to control the equipment is necessary to receive only the address that the Robotino passes to the program via network or Wi-Fi.
