The main aim of this research has been to analyze the identity patterns of the teacher s staff of fundamental education public schools in the Metropolitan Area of Natal-RN. It sets out from the hypothesis that being a teacher within this context grows out of the regularities of a specific habitus, which, according to Bourdieu, develops into mental schemes of thought and action within a specific social group. This habitus forms the basis on which is built the social representation of being a teacher prevailing in the group, as well as the symbolic differences that typify its identity variations. Three data sources have been fundamental in building up this thesis: (a) formative essays of students graduating from a Higher Teacher s Formation Course, as well as observing some of the public defense of these essays during field work; (b) a questionnaire aimed at classifying economically, socially, and culturally a sample of public teachers of the Natal-RN county; and (c) submitting a sub-sample of this group to the process of Multiple Classification Procedures (MCP). The analysis of data was done according to the multidimensional, non-parametric statistical procedures of both the Category Content Analysis and Enunciation Analysis methods. The results of the analysis took into account an ample set of variables, its associations and implications, the cultural and social profile of the population under scrutiny, their life styles, as well as the strategies they developed in the process of becoming a teacher, and the social representation of being a teacher . We came to the conclusion that the social identity of the teachers corps, or as we prefer to say it being a teacher , is a result of a set of regularities produced by the habitus that gives social shape and meaning to the existence of the group proper. We note the existence of identity variations caused by the variables (a) educational level; and (b) mode of action in fundamental education (if these are the first or last grades where the subjects operate). However, these variations will not break the power of the regularities that give shape, meaning, and social visibility to the group. The social representation of being a teacher points to the tensions, ambiguities, and trends inherent to common sense, as well as to a strong tendency to reassign a new meaning to being a teacher. Our thesis, therefore, is that the identity configuration of the teachers corps under scrutiny is characterized by an integrative synthesis, by-product of a habitus that is superimposed, and at the same time co-exists with different identity variations

Teaching is an activity inherent to the human condition. Historically, from the institutionalization of education, the key role to pursue that activity has been attributed to the teacher, who is required to adapt to the demands of each historical conjuncture. Currently, according to the new paradigmatic requirements, the teacher must possess various skills in order to handle the complex and challenging act of teaching. Assuming the existence of a gap between what the State and the scientific discourse recommend the teacher act upon in the classroom, a decision was made to identify the configuration and structure of social representation in the act of teaching, put forth by elementary school teachers in the public schools of Natal, RN, Brazil. Therefore, the research relied on the theoretical model developed by Domingos Sobrinho (1998, 2000, 2003), which articulates the praxeology of Pierre Bourdieu with the theory of social representations of Serge Moscovici (1978). It was intended to demonstrate how teachers habitus, in its due historical context, directs the construction of social representations in the act of teaching which guides the actions of the teacher, particularly in the classroom context. At the methodological level, the following methods and techniques were used: bibliographic and documentary review in order to identify the scientific discourse on the subject matter and the official parameters of educational regulation and the act of teaching; the Procedure of Multiple Classifications PMC in order to capture the configuration and structure of the representational content in focus, the direct observation of the classroom to identify in actual terms the social representation as "guide to action" as the theory preaches. From the standpoint of the analysis, quantitative data were analysed through Multidimensional Scaling MDS, covering in this study the Multidimensional Scale Analysis MSA and Smallest Space Analysis SSA; and non-parametric statiscal techniques. Additional data of qualitative value had to undergo categorical content analysis. It was then concluded that the teachers investigated guided themselves by social representation, the product of collectively constructed and shared assumptions about the act of teaching, forming a synthesis of different sources of information and knowledge acquirement, involving elements of common sense, religious habitus, pedagogic models considered outdated, the agencies responsible for teacher training and the hegemonic discourse about education today

Nowadays the discussion about providing a quality education for all students is more and more recurrent, including for those who have special educational necessities. The discussion increases regarding that it is not enough to include these students in the regular school, but also to provide conditions of learning and development. This requirement implies changes in the educational system, as well as in the teachers‟ everyday; and these changes manifest themselves through the complexity of the functions which are assigned to the teachers and the school. The news that are generated from the perspective of the inclusive education asks for new formative models for teacher‟s performance, once he tries to (re)build knowledge, knowings and doings among troubles and conflicts as a way to decrease the impact caused by the necessary transformations. This research approached this context in order to understand the social representation about the inclusive education from teachers who work in the regular public school system in the Municipality of Cruzeiro do Sul, State of Acre. To approach the symbolic content, we elected the Multiple Classification Procedure (MCP) as the methodological approach. For that, it was necessary to apply the Technique of Free-Association of Words (TFAW) to 60 participants what provided data to the first step of the chosen methodological procedure. The criterion of choice of the participants took into account if they dealt with student who has special educational necessities and with public schools. Later, we applied MCP to 50 teachers from specialized course in inclusive education subgroup 01 and 30 teachers who has no specialized formation subgroup 02. The collected data from this step was examined through multidimensional and content analysis for a better understanding of their symbolic dimensions. The results from the multidimensional analysis showed that the subject inclusive education‟ for subgroup 01 involved the following facets: circulating discourses that meant the naming of the characteristics that teachers think indispensable to inclusive education; teachers in relation to the inclusive practice that was focused on the relation between teaching and included student, and repercussion to the student that showed the advantages that the inclusive education provided to the student who has special educational necessities. Subgroup 02 dealt with the following facets: characteristics of the included student that approached teachers‟ view on this student; negative aspects that regarded the naming of the obstacles in the achievement of inclusive education; and teacher‟s relations to the inclusive education that approach professional, affective, and formative elements. The content analysis revealed four categories: disagreeing concepts; conception of inclusive education; dimension of the teacher‟s inclusive doing, and difficulties and resistance to carry out the inclusion of a student who has special educational necessities in the regularschool. Both analyses multidimensional and content one showed that the constitution of elements in a social representation of inclusive education was a mixture formed by the characteristics of this sort of education and the school integration, materialized on the figure of the different‟ student. The representational field of the subject inclusive education‟ was associated to the social representation of the student who has special educational necessities, making clear the deficiency/ difference, and causing the difficulty of the teachers in achieving what they say about the phenomenon

Being a teacher is a challenging task, driving action strategies that mobilize technical dimensions of being / doing teaching, but also affection. This research was conducted with teachers / students of the Special Program of formation for Teachers of Basic Education agricultural zone (PROFIR) developed by the Federal University of Acre in partnership with the State Department of Education (SEE) and City Halls of the region; locus typically Amazon and, in this research, comprises five municipalities in the Valley of Juruá - Acre. Northern Brazil. It Aims to capture the social representation of being a teacher in riverside communities. We performed this study from the Theory of Social Representations (MOSCOVICI, 1978, 1990, 2005a, 2005b, 2009, 2011) and (JODELET, 2001), from discussions on teacher formation (LDB No. 9394 of 1996). Work, among others, (TARDIF, 2004), (TARDIF; LESSARD, 2007), (NÓVOA, 1992, 1999), (ARROYO, 2007). We used as a methodological strategy, the multiple classification procedure (PCM), which is organized in two steps: Free Classification and Directed Classification, as well as semi-structured interviews, involving, thus, 137 teachers surveyed. For the analysis of the data, we appealed to software SPSS, version 13.0 for Windows, mapping the elements of the representational content through Multidimensional Analysis (MSA and SSA). Through the different strategies of analysis, we identified from the Free Classification, the regionalization: Beyond forest, teaching Attributes and Mobilized Attributes. With data of the Directed Classification, the analysis was based on the Theory of Facets (BILSKY, 2003) and (BUSCHINI, 2005) and we found: Reference of teacher; Negative Dimension and affective and technicians attributes. Finally, with the Analysis of Content (BARDIN, 2004) e (FRANK, 2005) and of the interviews the categories we found the categories: Urban relation versus agricultural, Knowledge in construction and possible bets. The report of the experiences along the edge of the rivers, in these different methodological strategies and of analysis, demonstrates the existence of symbolic and representational elements that influence and guide the educational conduct and actions of these teachers and that they are deeply anchored and objectified in technical and affective elements of the making teacher. They daily live deeply the concreteness of the Amazonian realism redesigning the Real and the symbolic one as a way to understand themselves as a teacher in adversity of this context. We also observed the historical, social and cultural local marks, framing, thus, the collective personality and generating its guides of action

Evidence of learning object like representation to social teachings that active in the education of young and adult with the point of view of the ―To be teacher‖ in this modality of teaching, to direct the intention, this research is way, understand the existence of this representation in center acting teachers in the initial periods of the EJA in the Rio Grande do Norte and its reasoning the theories of social representation (MOSCOVICI, 1978, 2003; JODELET, 2001; ABRIC, 1998). We interviewed one hundred and ten (110) teachers who work at schools in the Metropolitan Regions of Natal. We use two procedures: focal group (GATTI, 2005) and multiple classification analysis MCA (ROAZZI, 1995).Thus us with the focal group, attended by eight (08) teachers and seek to know understanding their ideas about EJA, what was possible from the content analysis (BARDIN, 1977; FRANCO, 2007) of the following category: the teacher s view of the EJA context. Developing the MCA, we met twenty (20) teachers in the first stage, free-word association technique FAT (ABRIC, 1998), and ninety in the second stage, including the participants of the focal group. The results of this procedure were submitted to multidimensional analysis and content analysis. The first showed three facets: having and being teacher dimension (ideal), which was about the example teacher s characteristics and behaviors; teacher/ student relation which was about the difficulties and doubts of this relationship as well as its success; at last, conflicting dimension from/ with practice, based on the conflicts experienced by the teachers as EJA workers. Content analysis based on the theme organization from the interpreted data showed four categories: resources to be a teacher which also brought out the definition of an ideal teacher; talk about teaching which disclosed teachers thoughts about the knowledge and being a teacher; obstacles to EJA which showed situations and conditions that prejudice EJA development; and also admission as EJA teacher: viewing reasons which revealed the reasons why teachers went to EJA even though they were formed to deal with children. The conjoint analysis us evidenced the little the dominion of the teachers a participation these search at respect of origin, of the meaning of the character while the singular of EJA modality of teaching the conformation of the social representation from the ―To be‖ on the general vision dissociating with it of inexistence of a social representation of ―to be teacher of the EJA‖ white striking element in the reference at singularity that define the related modality of teaching

Cuando consideramos los procesos de formación del profesorado pensamos en los nuevos conocimientos que podrían ser aprendidos por los estudiantes involucrados, centrándose en el debate de cuales contenidos y conocimientos deben estar presentes en la formación que se desea para estos profesionales. El propósito de esta investigación es analizar el tema desde un ángulo diferente, invertido, desde la perspectiva de los estudiantes de pedagogía en la formación inicial, mirando cómo utilizan los conocimientos adquiridos durante la licenciatura, en un proceso de construcción y reconstrucción de los conocimientos que empiezan a permear a sus prácticas pedagógicas. Dado este marco, nuestro propósito ha sido estudiar los elementos de construcción de la identidad de los futuros licenciados en Pedagogía por la UFRN, intentando caracterizar las representaciones sociales expresadas por estos estudiantes acerca del trabajo del maestro, a través de la identificación de los elementos definidores de las dichas representaciones (conocimiento del contenido de estas) y la comprensión de la forma dinámica de organización de tales elementos. Tomamos como referencia la teoría de las representaciones sociales (MOSCOVICI, 1978), que proporciona una idea de cómo los futuros docentes construyen sus representaciones acerca de los objetos de conocimiento que rodean la formación docente. Participaron del estudio 120 estudiantes de la graduación en Pedagogía, cuándo nos acercamos a los contenidos simbólicos traídos por ellos utilizando el Procedimiento de Múltiples Clasificaciones (PMC) como el enfoque metodológico. El material incautado por tal procedimiento se sometió a análisis multidimensional (Smallest Space Analysis (SSA) y Multidimensional Scalogram Analysis (MAS)) y de contenido, con la intención de un entendimiento más amplio de las dimensiones simbólicas. Los resultados de la investigación mostraron las siguientes dimensiones: la afectiva, con el nombramiento de las características necesarias a construcción simbólica del maestro; la formativa, que resalta los elementos necesarios para una enseñanza profesional; el aspecto ético y profesional, que aborda los elementos necesarios para el desempeño docente, en la perspectiva de transformación social mediante la educación; y la dimensión conflictiva, poniendo de relieve las dificultades del trabajo docente. Por lo tanto, estos aspectos muestran que la representación de ser maestro, construida por los estudiantes en la formación, parece constar de diferentes matices, articuladas y complementares, que dan sentido a la profesión, lo que justificará la práctica diaria de los futuros profesionales

This research aims to understand the social representations Teaching Work in groups of undergraduate students of Physics and Chemistry of the Federal University of Rio Grande do Norte. For this, the proposal was based on the three theoretical and methodological consensus Carvalho (2012) in the explanation of socio-genetic mechanisms constituents of dynamic consensus that has functionality to your organization. It Was used to achieve this goal, the theoretical-epistemological Serge Moscovici (1978, 2003), Jodelet (2011), Wagner (1998,( 2011) and Carvalho (2012). The corpus analyzed results from a qualitative and quantitative research, developed in three stages. The first two (2) questionnaires to fifty (50) of each undergraduate course, a questionnaire and another profile for collection of free associations concerning motes inductors "Give Lesson," "Student" and "Teacher". The second step in the procedure Multiple Classifications, Roazzi (1995), aimed for another thirty (30) undergraduate students for each course, as well as Document Analysis of Educational Projects Curriculum courses in Physics and Chemistry. The data analysis of the first stage focused on descriptive statistics and frequency and average order of the words associated with motes inductors. The results from the Multiple Classification Procedure submitted to multidimensional analysis (MSA multidimensional scalogram analysis) and SSA (Similarity Structure Analysis), were interpreted by the theoretical and methodological proposal of the three consensus, supported by analysis of the rhetorical nature of justifications classifications and categorizations of words, boosted in times of application of Procedure Multiple Classification. The data revealed that the groups surveyed were the same Social Representation with specific dynamic consensual. Thinking Teaching Work for these groups it is considered in three dimensions: the BE-DO-HAVE of teaching. In the group of Physics consensus was clear semantic, which expressed a dynamic in which the interpretations of "Teaching Work" peacefully coexist on perceptions of two concepts: An identity around the "BE" "Teacher" or "BE" "Educator" and the other, how they think about professional development. The type of group consensus Chemistry pointed to a consensual logic hierarchical order in which the gradual between the elements of BE-DO-HAVE attested conflicts and disagreements about the perceptual object "Teaching Work", around what value most, whether they are the attributes of personal or professional-technical dimension of teaching, in the course of professional development. The thesis to explain the mechanisms of socio-genetic Representation Social Teaching Work by theoretical and methodological proposal was confirmed

The aim of this study was to analyze the social representation of the sensible among teachers of the Federal Institute of Education, Science and Technology of Rio Grande do Norte, attempting to identify its constituents and understand the dynamics that gives functionality to your organization. The study is significant considering that the professional conduct can not be delineated in its complexity without unraveling the social representations that teachers themselves have of their being and doing professional. The theoretical and methodological framework of the research is the theory of social representation. 107 teachers from various backgrounds participated. To collect the data were used as instruments : a questionnaire listing, which subsidizes the characterization of the subjects , the TALP - technique of free association of words ( ABRIC , 1994) , the PCM - Procedure for Multiple Ratings ( ROAZZI , 1995) ; questionnaire redemption of sensitive memories of the subjects in their school experiences of childhood , adolescence, youth and teaching practice . The PCM data, in which the slogan was directed at rating Give class, were submitted to multidimensional statistical analysis. Already TALP was analyzed by EVOC 2000 software, the profile questionnaire received descriptive statistical analysis and the memories received the questionnaire analysis of thematic content, Bardin (2004). Taken together, the results point to a social representation of sensitive teaching (the game, the fun, the touch, the smile, the relaxation) are not in the classroom. The sensitive pure still fits in school, but only in the courtyard, on the playground, in the intervals, therefore, outside of space-time class, playful perch that lives in each of us is totally strange to this world of the classroom . After doing the Approximation of ideas , we realized three discourses evident in the reports of teachers : the discourse of Numbness in which we perceive the distance of the teacher in relation to sensitive component as a facilitator in the learning process , the discourse of Feeling , in which we can discern small approximation to the sensitive dialogues and proposed in this study , the speech of reflection in which teachers analyze, evaluate and establish a discourse on the importance of education in sensitive , but not actualize in their teaching practice

We seek, through this study, to analyze about social representation that the students of licentiate degree course of the Federal Institute of Education, Science and Technology of Rio Grande do Norte - IFRN - have about didactic-pedagogical subjects. We utilize the Social Representations Theory (MOSCOVICI, 2009; 2012; JODELET, 2001) as a theoretical and methodological contribution and as aim, we identify this social representation and understand how it is influenced by the formation of these undergraduates. So we developed the research under the seven undergraduate classroom courses offered by IFRN, namely: Biology, Spanish, Physics, Geography, Computer Science, Mathematics and Chemistry, covering units located both in the capital and in the countryside. While methodological approach we used the Procedure of Multiple Classification (PMC) - (ROAZZI, 1995), whose realization requires a set of words achieved through of Free Technique of Words Association - FTWA - (ABRIC, 1998). For this realization we have a total of one hundred twenty (120) participants, with thirty (30) in FTWA and other stage in the realization of free classification and directed that correspond to the MPR. Achieved the empirical data, we use the analysis of content (BARDIN, 2011; FRANCO, 2007) and multidimensional (ROAZZI, 1995) for the course of his interpretation. Finally, we identify the social representation of didactic and pedagogical subjects centered around the idea that it is through these subjects that can achieve the profile of "good professional" as one who gathers knowledge and attributes required for the full development of teaching involving capabilities it and characteristics that mark the sense of professionalism. Furthermore, we found that the anchoring social representation on the understanding that these disciplines "teach the teacher to be" in the image and its objectification of the "good teacher", ie, one that reaches through the training process and experiences, qualities that make it unique and able to carry full professional. Still see that the actions of the teacher trainer affects the way students perceive, assume and engage in the study of teaching and pedagogical subjects and it reflects significantly the social representation then created

En esta investigación, se busca comprender los procesos de formación de pregrado del Curso de Cartas da UFRN, de estas representaciones sociales acerca de los estudiantes de enseñanza. Por lo tanto, el objetivo fue conocer y analizar las representaciones sociales de curso de pregrado UFRN Cartas sobre la enseñanza. Por lo tanto, se aplica la Técnica de Libre de Palabras Asociación (TALP) con 20 participantes, después de haber sido probados individualmente, utilizando como estímulo palabra "enseñar" y limitar el número de invocaciones a 03 palabras por participante. Esta técnica fue elegida porque es una técnica proyectiva que permite la reducción y racionalización permite acceder al campo semántico de las representaciones sociales, en nuestro caso, en la enseñanza del de pregrado do Curso de Cartas da UFRN. Por lo tanto, llegamos a total de 60 llamadas, análisis de frecuencia después de 41 y 24 después de un análisis del significado que se utilizaron en otro procedimiento aplicado en esta investigación, las calificaciones de Procedimiento de Múltiples Calificaciones (PCM). Estas palabras, sobre la base de las justificaciones de las evocaciones y significados que atribuyen participantes en la investigación, se dividieron en 4 campos semánticos: Campo 1: Aspectos técnicos de la enseñanza, Campo 2: aspectos volitivos, Campo 3: aspectos relacionales de la enseñanza y de Campo 4: Elementos del campo. El PCM se aplicó de forma individual, con 50 estudiantes. Para el análisis de los datos generados, utilizamos Análisis Multidimensional (MDS) para la Escala Multidimensional de Evaluación Análisis gratuito (MSA: Multidimensional Scalogram Analysis) y el análisis de clasificación selectiva de los espacios menores (SSA: Smallest Space Analysis). El mapa generado por el análisis de MSA fue dividido en tres regiones: Aspectos de los aspectos de enseñanza, capacitación y asistencia técnica de los promotores de la profesionalización, la primera región que tiene una sub-regionalización llamada dimensión negativa. El mapa de la SSA análisis se dividió en dos partes y un subfaceta, llamado el aspecto faceta técnica de la enseñanza y la formación, la segunda faceta llamado Vínculo entre el campo y la enseñanza específica y su nombre subfaceta aspecto relacional. Del análisis del contenido de las justificaciones de la PCM, llegó a 5 categorías, a saber: Hacer la enseñanza, la faceta negativa, Escuela, Formación y faceta afectiva del profesor. El TALP aporta pruebas de que algunos de estos estudiantes ve la oportunidad de adquirir unos conocimientos en esta área, la formación en un nivel superior, como quieran, simplemente tienen un título universitario para realizar licitación abierta. El PCM nos ha hecho comprender que el contenido representacional en cuestión se configura desde el universo consensual conectado a la profesión y la formación. Por lo tanto, podemos decir que los titulares de licencias con respecto al tema estudiado anclar la representación social de "enseñar" a la imagen de ser un maestro y objetivar la imagen de la profesión

The aim of this study was to investigate the social representation of technological education teachers at the Federal Technological Education Network. The survey was conducted from 2007 to 2010, and the respondents were 275 teachers, 135 of the Federal Center for Technological Education (CEFET in portuguese) in the state of Amazonas, in Manaus unit headquarters; 140 of the CEFET in the state of Rio Grande do Norte, a unit based in Natal. We adopt the concept of technological education as the top level of professional education, that is to say, the undergraduate programs of short duration called technological courses. The Federal Technological Education Network gathers hundreds of related institutions, coordinated and supervised by the Office of Vocational and Technological Education of the Ministry of Education. Although many of these institutions offer courses in technology education, no research addressing this subject from the perspective of Social Representations Theory (SRT) was found in the literature. We seek to unravel the social representation of technological education of the teachers by adopting the procedural approach of SRT. This is a qualitative approach, focusing on significant aspects of the representative activity and the formation mechanisms of the representation. Therefore, we search the socio-genesis of the representation in the articulations between discourses, social institutions and practices. We initiated the research through applying critical reading and an analytical perspective on the historical and regulatory documents of technological education in Brazil, from the early twentieth century to the present day. We adopt the Procedure for Multiple Classifications (PMC) from the Free Words Association Technique (FWAT) to access the elements of representational content. For the analysis of the data obtained with FWAT and selection of major words / phrases pertinent to the semantic field of education technology, we used Hamlet II software. For the data analysis of PMC and Free Classification (FC) we used the SPSS ® (Statistical Package for the Social Sciences) version 17.0 and used the method of multidimensional scaling - Multidimensional scaling - (MDS). The output from the central MDS takes the form of a set of scatterplots - "perceptual maps" - of which the points are the elements of the representational content. For the FC data analysis we used the Scalogram Multidimensional Analysis (SMA) - which makes use of the original data in its raw form and allows categorical data to be interpreted in the map as measures of (di)similarity. In order to help with the understanding of the settings of the perceptual maps of FC, we used the Content Analysis of the discourse fragments of the teachers interviewed. The results confirm our initial hypothesis regarding the presence of a single plot among the socio-cognitive study subjects, which is the basis for a social representation of technological education in line with the historic assumption of the dichotomy between mental and manual labor. In spite of the three merging representational elements of the representational content, the perceptual maps compiled from the MSA statistics corroborates the dichotomy, with the exception of the map relating to the subgroup of teachers belonging to the humanities

Trata-se de estudo descritivo, exploratório, transversal, quantitativo, realizado com mulheres em tratamento quimioterápico para neoplasias de mama, em Aracaju-Sergipe-Brasil. O objetivo foi avaliar a qualidade de vida relacionada à saúde (QVRS) destas mulheres que apresentaram reações adversas pós quimioterapia. Foram utilizados instrumentos contendo dados sócio demográficos, clínicos e terapêuticos, European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core30 e formulário de registro de toxicidades dos antineoplásicos. Na análise dos dados, foram utilizados análise descritiva, cálculos de percentual, teste de Shapiro-Wilk, coeficiente de correlação de Pearson ou de Spearman, teste de ANOVA ou Kruskal-Wallis. Os resultados mostraram dados de 206 mulheres, a partir da segunda sessão de quimioterapia, com média de idade de 53,1 anos, maioria procedente de Sergipe, com Carcinoma Ductal Infiltrante, estadiamento III. A maioria realizou cirurgia oncológica, não realizaram radioterapia devido à grande fila de espera, o protocolo de quimioterapia mais comum foi TAC (docetaxel, doxorrubicina e ciclofosfamida). Quanto às reações adversas, a maioria não apresentou alterações hematológicas e metabólicas no momento da coleta das informações, nas alterações funcionais, a fadiga foi presente em 80,8% dos casos, de forma moderada. Nas alterações gastrintestinais, diarreia, constipação, mucosite, náusea, vômito e dor abdominal foram citadas pela maioria. Nas alterações dermatológicas, a alopecia, hiperpigmentação na pele, alterações nas unhas, prurido na pele, descamação e eritema multiforme foram citadas pelas entrevistadas. Nas alterações cardiovasculares, hipotensão e HAS sobressaíram-se. Nas alterações neurológicas, neuropatia periférica, perda da audição e zumbido foram comuns. Os resultados da avaliação da QVRS foram analisadas à luz do referencial teórico de Ferrel et al. (1995) com os seguintes resultados: média do escore 76,01; escalas funcionais apresentaram escore baixo, com aspectos físico, emocional, cognitivo, funcional e social bastante afetados após o tratamento, o desempenho de papéis e função emocional foram os mais prejudicados; na escala de sintomas, os domínios mais prejudicados foram: dificuldades financeiras, fadiga e insônia. Na análise de correlação, o escore geral da QVRS apresentou correlação estatisticamente significante com a quantidade de reações adversas na medula óssea. Em todos os casos estatisticamente significantes o domínio emocional apresentou correlações positivas e o domínio dor, correlações negativas. A idade apresentou correlação estatisticamente significante e negativa com os domínios físico e dificuldades financeiras e positiva com perda de apetite. Pelo procedimento de comparações múltiplas, as diferenças ocorreram entre os estados civis casado e separado e também casado e solteiro, entre as religiões católica e evangélica, entre os ensinos fundamental e médio e entre médio e superior; para a extensão da doença os domínios dor e insônia apresentaram diferenças estatisticamente significantes entre as categorias de extensão. Para renda mensal, os domínios fisico, desempenho de papel, emocional, constipação e dificuldades financeiras apresentaram diferenças estatisticamente significantes entre as categorias de renda. Nos domínios fisico, desempenho de papel e emocional as diferenças ocorreram entre as faixas de 1 a 3 e mais de 6 salários. Concluiu-se que as reações adversas causadas pelo tratamento antineoplásico com quimioterapia afetaram de algum modo as pacientes, causando déficits em vários domínios, prejudicando assim sua QVRS

O sector da cortiça apresenta uma grande importância em Portugal, o líder mundial na sua exportação. Liderança encabeçada pelo Grupo Amorim, o líder mundial na transformação da cortiça. A cortiça, um material de excelência, apresenta múltiplas aplicações, das quais a mais rentável é a rolha natural, seguida da rolha técnica. É nesta última que a UI-Equipar se foca e na qual a presente dissertação foi realizada. Este material encontra-se sobre um grande escrutínio em termos de qualidade. Apresentando-se a contaminação por 2,4,6-tricloroanisol como um dos factores mais alarmantes. A presente dissertação visa a melhoria na caracterização da cortiça de trituração para quantificação de 2,4,6-tricloroanisol, ou TCA, no controlo deste composto no início do processo produtivo. Para tal, elaborou-se uma hipótese de trabalho na qual se avaliou a aplicação da trituração da cortiça no controlo em estudo. Realizaram-se uma serie de análises sobre as aparas Refugo, Broca e Especial em que se averiguou o efeito da área de exposição, da representatividade da amostragem, do volume de análise e da presença das partes mais sujas da cortiça, as Terras. As evidências apontam para que, apesar da grande heterogeneidade quanto à presença de 2,4,6-tricloroanisol, apenas para a apara Refugo e para a apara Broca a percentagem de detecção de contaminações por TCA aumenta em consequência do aumento da área de exposição do material em análise e através de uma melhor representatividade da cortiça (comparativamente ao procedimento actualmente em prática). Mostra-se ainda que para a apara Refugo e para a apara Broca os resultados obtidos da análise de cortiça triturada são estatisticamente diferentes dos resultados das análises em apara e que da implementação de meio litro ou dois litros; e da presença ou ausência de terras não se obtêm diferenças estatisticamente significativas. Recomenda-se que a amostragem complementada com a trituração, com uma maceração em meio litro, seja aplicada às aparas Refugo e Broca, mantendo-se inalterada o controlo sobre a apara Especial.

The present work deals with the ana1ysis of microstrip patch antennas printed on tapered dielectric substrates. We investigate the influence ofthe substrate height variations on the properties of configurations such as microstrip patch antennas, microstrip patch antennas with overlay and suspendeô microstrip patch antennas. The dielectric substrates can be isotropic or anisotropic ones. This accurate analysis is based on the full-wave formulation. It is carried out initially for the determination of the impedance matrix, through the use of the spectral¬domain immitance approach. We use a model based on a segmentation of the considered line into uniform microstrip line subsections. Normalized phase constants and characteristic impedances are obtained by means of the Galerkin numerical technique. Then, the cascaded combination of the uniform microstrip subsections are analyzed through an interactive procedure. Numerical results are presented for the input reflection coefficient, voltage standing wave ratio, resonant frequency, and radiation pattems ofthe E_plane and H-plane diagrams. It is found that the variations in the substrate height profile produce a great influence on the bandwidth of microstrip antennas. This procedure gives bandwidth improvements without altering considerably the resonant frequency. Furthermore, the tapered microstrip antenna can be used as a lightweight altemative for bandwidth control and to eXtend the use of microstiip antenna technology to a wider variety of applications. Finally, suggestions for the continuity of this work are presented
