The first one, composed by 62 men, aimed to evaluate the spinal cord injury impact on human sexuality, trying to identify the significantly affected sexual components. It was possible to verify alterations between the pre and post-injury periods: frequency and number of sexual partners significant reduction; anal sex practice considerable decrease; considerable modifications in the sexual preferences for hugging, vaginal penetration, vibrator use; variation in the pleasure originated in the following erogenous zones: mouth, neck, penis, thighs and legs; alterations in the sexual functions with significant reduction of the levels of desire, arousal and ejaculatory excitement, orgasm, as well as dysfunctions; sexual satisfaction significant reduction, even though some perceived alterations are equal to the general population. The results confirm the importance of giving assistance to the sexual sphere of these patients and found the proposal of sexual rehabilitation, serving as indicator. The second study involved the same population and aimed to analyze the sexual counseling, as well as understanding the post-injury sexual self-adaptation process. Between results, it was observed that less than half of the participants and only about one sixth of the partners received some type of sexual counseling. It was verified that the self-adaptation consists of a process influenced by some factors: age of incidence and time-of-onset, quality of received information, not being always successful, possessing peculiarities, such as the distinction between presence and absence of previous sexual experience before injury. The third study was composed by 25 people among researchers, relatives, health professionals, spinal cord injured men and their partners. It aimed to elaborate a sexual rehabilitation proposal that reflects the target population yearnings, necessities and potentialities. It was developed by means of Grupo Interdisciplinar de Apoio à Sexualidade Adaptada - GIASA, characterized by weekly 90 minutes meetings, divided in two stages: the first one, carried through May to September 2007, aiming to identify the pertinent subjects and the second one, between October and December 2007, with the purpose of presenting and discussing the subjects mentioned in the previous stage and to suggest evaluated strategies for the participants. While the first stage meetings had been marked by the discussion of free subjects, related to the sexuality, the second was composed for two moments: the first one, marked by seminaries, involving theoretical intervention on the previously definite subjects, with posterior opening for discussion, experiences exchange, reflection about the subjects and their respective approach, characterizing the focal group; and a second moment, where strategies characterizing the therapeutical interventions were applied, assessed and carried through interdisciplinarly, trying to involve the participants actively as citizens in the processes of focal discussion and theoretician-therapeutical intervention for the resolution of the diagnosed problem and considered for this research. Finally, based on the stages of the GIASA, it was elaborated a proposal of sexual rehabilitation called Grupo Interdisciplinar de Apoio à Saúde Sexual - GSex, generally directed to the community, and specially directed to the physically challenged people and/or chronic illnesses, being defined: purpose, action methodology, theoretical basis, principles, members functions, actions delineation, attendance process, among others topics. / A pesquisa desenvolveu-se mediante três estudos. O primeiro composto por 62 homens objetivou avaliar o impacto da lesão medular sobre a sexualidade humana, buscando identificar os componentes sexuais significativamente afetados. Verificou-se alterações entre os períodos pré e pós-lesão medular: diminuição significativa da freqüência e número de parceiros sexuais; redução sensível da prática sexual de sexo anal; modificações consideráveis nas preferências sexuais por abraço, penetração vaginal, utilização de vibrador; variação no prazer advindo das zonas erógenas da boca, pescoço, pênis, coxas e pernas; alterações nas funções sexuais com redução significativa dos níveis de desejo, excitação e orgasmo, bem como disfunções erétil e ejaculatória; redução significativa na satisfação sexual, embora algumas alterações percebidas equiparam-se à população em geral. Os resultados confirmam a importância de se prestar assistência à esfera sexual desses pacientes e embasam a proposta de reabilitação sexual, servindo como indicadores. O segundo estudo composto pela mesma população objetivou analisar o aconselhamento sexual e compreender o processo de auto-adaptação sexual pós-lesão medular. Entre os resultados observou-se que menos da metade dos participantes e apenas cerca de um a cada seis parceiros recebeu algum tipo de aconselhamento sexual. Verificou-se que a auto-adaptação consiste em processo influenciado por vários fatores: idade de incidência e tempo de lesão, qualidade das informações recebidas,não sendo sempre exitoso, possuindo peculiaridades como a distinção entre presença e ausência de experiência sexual prévia à lesão. O terceiro estudo foi composto por 25 pessoas entre pesquisadores, profissionais da saúde, homens com lesão medular, parceiras e familiares objetivando elaborar proposta de reabilitação sexual que refletisse os anseios, necessidades e potencialidades da população destinada. Desenvolveu-se por meio do Grupo Interdisciplinar de Apoio à Sexualidade Adaptada GIASA, caracterizado por encontros semanais com 90 minutos de duração, em duas etapas: a primeira realizada entre maio e setembro de 2007 que objetivou identificar os temas pertinentes e a segunda, entre outubro e dezembro, com a finalidade de apresentar e discutir com propriedade os temas propostos pela etapa anterior e sugerir estratégias avaliadas pelos participantes. Enquanto os encontros da primeira etapa foram marcados por discussões de temas livres relacionados à sexualidade, a segunda foi composta por dois momentos: um marcado por seminário, compreendendo intervenção teórica sobre os temas previamente definidos, com posterior abertura para discussão, troca de experiências, reflexão quanto à temática e forma de abordagem, caracterizando o grupo focal; e um segundo momento, onde foram aplicadas e avaliadas as estratégias caracterizando as intervenções terapêuticas, realizadas interdisciplinarmente, procurando-se envolver os participantes ativamente como sujeitos nos processos de discussão focal e intervenção teórico-terapêutica para a resolução do problema diagnosticado e proposto por esta pesquisa. Por fim, baseando-se nas etapas do GIASA, elaborou-se a proposta de reabilitação sexual denominada Grupo Interdisciplinar de Apoio à Saúde Sexual GSex, voltado à comunidade em geral, em especial a pessoas com deficiências físicas e/ou doenças crônicas, sendo definidos: finalidade, metodologia de ação, fundamentação teórica, princípios, funções dos membros, delineamento das ações, processo de atendimento, entre outros tópicos.

A Física tem uma maneira própria de olhar a natureza e de estudar seus fenômenos. Por essa razão, o ensino-aprendizagem de Física não pode estar centrado na transmissão de informações, mas sim na construção do conhecimento em um contexto amplo que envolva conteúdos, novas metodologias e novos instrumentos adequados à realidade da escola, que venham a contribuir para uma aprendizagem significativa. Dentro dessa concepção, apresenta-se uma proposta de ensino de ótica, com ênfase no estudo através de módulos didáticos. Para tal, foram elaboradas atividades didáticas incluindo simulações de eventos com o uso de novas tecnologias e, também, em laboratório convencional, exploradas em uma visão construtivista fundamentada nas teorias de Vygotsky e de Ausubel. No desenvolvimento dessas atividades procurou-se propiciar o compartilhamento de significados através de diagramas fundamentados no V de Gowin, na busca de uma aprendizagem significativa. A composição dos módulos didáticos apresenta uma motivação inicial através de exposição oral questionada, com o objetivo de despertar no aluno seus conhecimentos prévios. Em cada um dos módulos didáticos são sugeridas uma ou mais atividades a serem trabalhadas em grupos de 3 a 4 alunos, constando de experimento virtual (applets, simulações) ou real, acompanhado de guia simplificado. Essa dinâmica de trabalho gerou uma maior interação social entre os alunos; ao professor, coube o papel de mediador da atividade. Paralelamente a cada atividade, cada grupo de alunos construiu um diagrama V, que era apresentado à turma posteriormente, com o objetivo de promover discussões. A aplicação da proposta foi realizada no quarto bimestre letivo do ano de 2006, em uma turma de terceira série de Ensino Médio, noturna, da Escola Estadual de Ensino Médio Dr. Araby Augusto Nácul, em Lagoa Vermelha, RS. O material instrucional elaborado, na forma de página da Web, contém as atividades propostas nos módulos didáticos e também os correspondentes diagramas V a serem construídos pelos alunos. Também são incluídos na página da Web, como links, um material de apoio, com os conteúdos desenvolvidos nos vários módulos, e uma seção contendo exercícios de fixação. Com os alunos trabalhando em um determinado módulo didático, o material era disponibilizado nos computadores da Escola, gradualmente, para evitar que avançassem para os módulos seguintes antes de refletir sobre o conteúdo da atividade em andamento. O produto educacional, contendo o material instrucional e orientações para o seu uso, será divulgado na série Hipermídias de Apoio ao Professor de Física para que outros professores da rede de ensino possam adaptá-lo a sua realidade escolar. / Physics has its own way of looking at nature and its phenomena. For this reason the Physics’ teaching must not only be centered in lecturing information, but must also construct the knowledge in a wide context involving new technologies and tools fitted to the schools' reality. This, together with physics concepts, is to build a meaningful learning. To accomplish these goals we propose an approach to Optics teaching, structured in six didactic modules based on the meaningful learning’s theory by D. Ausubel and the social interaction’s theory by L. Vygotsky. Each didactic module starts with an oral exposition presenting the motivation through challenging questions, in order to instigate the students’ previous knowledges. We then suggest one or more activities based on virtual (e.g., simulations, applets) or real experiments, with a schematic activities guide, to be worked out by groups of three or four students, with the teacher mediation, in order to deepen social interaction. Besides each experimental activity, they construct an adapted Gowin V diagram, intended to promote a meaningful learning, and finally they discuss with the rest of the class, encouraging an exchange of views about the proposed issue. This methodological proposal has been applied to 18 third high school year students, of the nightclass at "Escola Estadual de Ensino Médio Dr. Araby Augusto Nácul" at Lagoa Vermelha, RS, during the fourth bimester of the school year of 2006. The instructional material was developed as a webpage, including the proposed experimental activities and the related V diagrams. Among the webpage links, we also included additional material with the physics contents of the didactic units and exercises. The whole instructional material has gradually been made available on the School’s computers to prevent the students from going to a forthcoming activity before having made deep reflections on the lectures/subjects that were being worked out at each moment. This work is to be published in the series Hipermídias de Apoio ao Professor de Física, of Instituto de Física of UFRGS, so that other teachers can access this material and use it in their school's context.

In order to achieve this, a Geographic Information System (GIS) was used for the registration of deep wells, continuing the research with a study of natural vulnerability by mapping the information obtained wich relates the potential sources of contamination. Data collection took place through a consultation with the Information System for Groundwater (SIAGAS) and through the System of Statistics and Geographic Information of the State of Goiás (SIEG). Through the database development it was possible to apply the DRASTIC method adapted by Narciso and Gomes (2005) and GOD method proposed by Foster and Hirata (1988) for mapping vulnerability to contamination of groundwater resources. In order to apply the DRASTIC method adapted, maps were generated for slope, land use, geology, geomorphology, water resources and human occupation. The map resulting from this method shows four classes: low, medium, high and very high, showing that of the 288 square kilometers of this city, almost 80% were classified as having medium vulnerability fir the groundwater quality. For the GOD method, maps of the degree of hydraulic confinement, geology and depth or distance of the groundwater level were generated. The map resulting from this process had only three classes: negligible, low and high, showing that 76% of the area was classified as having a negligible vulnerability. This occurred because this method does not consider human occupation. / A pesquisa desenvolvida buscou contribuir para a conservação dos recursos hídricos subterrâneos, tendo como objetivo o desenvolvimento de um Sistema de Informação Geográfica (SIG) como instrumento de gestão para a utilização das águas subterrâneas visando o seu uso sustentável, para o abastecimento público na cidade de Aparecida de Goiânia/GO. Para atingí-lo utilizou-se um Sistema de Informações Geográficas (SIG) para o cadastramento dos poços tubulares profundos, procedendo assim ao estudo da vulnerabilidade natural, através do mapeamento das informações obtidas, além de relacionar as fontes potenciais de contaminação. A obtenção dos dados deu-se através da consulta ao Sistema de Informações de Águas Subterrâneas (SIAGAS) e através do Sistema Estadual de Estatística e de Informações Geográficas de Goiás (SIEG). Estes dados possibilitaram a elaboração do banco de dados e a aplicação do método DRASTIC adaptado por Narciso e Gomes (2005) e do método GOD proposto por Foster e Hirata (1988), para a geração de mapas de vulnerabilidade à contaminação dos recursos hídricos subterrâneos. Para a elaboração do método DRASTIC adaptado foram gerados os mapas de declividade, uso do solo, geologia, falhas geológicas, recursos hídricos e ocupação humana. O mapa resultante desse método apresentou quatro classes: baixa, média, alta e muito alta, sendo que dos 288 quilômetros quadrados deste município, aproximadamente 80% foi classificado como tendo vulnerabilidade média para a qualidade das águas subterrâneas. Para o método GOD foram gerados os mapas de grau de confinamento hidráulico, ocorrência do substrato litológico e profundidade ou distância do nível da água subterrânea. O mapa resultante desse processo apresentou apenas três classes: desprezível, baixa e alta, sendo que 76% da área foi classificado como vulnerabilidade desprezível, por este método não considerar a ocupação humana.

This thesis provides the explicit expression of the star-exponential for the action of normal j-groups on their coadjoint orbits, and of the so-called modified star-exponential defined by Gayral et al. Using this modified star-exponential as the kernel of a functional transform between the group and its coadjoint orbits yields an adapted Fourier transform which is also detailed here. The normal j-groups arise in the work of Pytatetskii-Shapiro, who established the one-to-one correspondence with homogeneous bounded domains of the complex space; these groups are also the central element of the deformation formula recently developed by Bieliavsky & Gayral (a non abelian analog of the strict deformation quantization theory of Rieffel). Since these groups are exponential, the results given in this text illustrate the general work of Arnal & Cortet on the star-representations of exponential groups.<p> As this work is meant to be as self-contained as possible, the first chapter reproduces many definitions introduced by Bieliavsky & Gayral, in order to obtain the expression of the symplectic symmetric space structure on normal j-groups, and of their unitary irreducible representations. The Weyl-type quantizer associated to this symmetric structure is then computed, thus yielding the Weyl quantization map for which the composition of symbols is precisely the deformed product defined by Bieliavsky-Gayral on normal j-groups. A detailed proof of the structure theorem of normal j-groups is also provided.<p> The second chapter focuses on the expression and properties of the star-exponential itself, and exhibits a useful tool for the computation, namely the resolution of the identity associated to square integrable unitary irreducible representations of the groups. The result thus obtained satisfies the usual integro-differential equation defining the star-exponential. A criterion for the existence of a tempered pair underlying a given tempered structure on Lie groups is proven; the star-exponential functions are also shown to belong to the multiplier algebra of the Schwartz space associated to the tempered structure. Before that, it is shown that all Schwartz spaces that appear in this work are isomorphic as topological vector spaces.<p> The modified version of this star-exponential is computed in chapter three, first for elementary normal j-groups and then for normal j-groups. It is then used to define an adapted Fourier transform between the group and the dual of its Lie algebra. This transform generalizes (to all normal j-groups) a Fourier transform that was already studied in the “ax+b” case by Gayral et al. (2008), as well as by Ali et al. (2003) in the context of wavelet transforms. / Doctorat en Sciences / info:eu-repo/semantics/nonPublished

La littérature apporte de plus en plus de preuves du bénéfice de la pratique d’une activité physique dans le cadre des préventions secondaire et tertiaire du cancer du sein, cancer le plus fréquent chez la femme. Ces travaux de thèse sont nés de la collaboration entre une équipe experte de la prise en charge clinique et de la nutrition de patients atteints de cancer (Centre de Lutte contre le Cancer Léon Bérard de Lyon) et une équipe experte de l’activité physique (Centre de Recherche et d’Innovation sur le Sport EA647). Cette approche « recherche-action » a permis d’implanter des programmes novateurs d’activité physique adaptée (APA) auprès des patientes atteintes de cancer du sein et ce, de manière concomitante aux traitements adjuvants. Les programmes d’APA complétés d’une prise en charge diététique apparaissent comme un moyen faisable et peu coûteux de lutter contre les facteurs reconnus de mauvais pronostic que sont la prise de poids, les risques métaboliques, mais aussi la problématique de l’inactivité physique et de la sédentarité qui s’installent dès le diagnostic de la maladie. Les résultats originaux de ce travail de thèse fournissent des avancées importantes pour promouvoir l’intégration de l’APA en tant que soin de support des patients atteints de cancer, tout au long des traitements et dans la phase de réhabilitation. Ces travaux permettent de fixer les modalités de prise en charge de ce public spécifique, mettant à disposition des professionnels du secteur un panel de connaissances scientifiques et pratiques. Ils démontrent ainsi la compatibilité et l’applicabilité directe de la recherche en milieu professionnel. / There is growing evidence for physical activity benefiting primary and secondary prevention of breast cancer, the most common cancer in women. This PhD is a collaborative work between experts in clinical care and nutrition in cancer patients (Léon Bérardcomprehensive cancer centre of Lyon) and experts in physical activity (centre for research and innovation on sport EA647). This “research-action” implemented pilot programs of adapted physical activity (APA) for breast cancer patients, concomitantly to adjuvant treatments. APA programs supplemented by dietetic counseling appear as a feasible and inexpensive way to fight against the known factors of poor prognosis, such as weight gain, metabolic risks, and also the problem of physical inactivity and sedentary lifestyles which tend to increase from the diagnosis of the disease. The results of this original research provide proofs of relevance of integrating APA programs as supportive care of cancer patients, throughout treatment and rehabilitation phase. This work shows the modalities for programming APA for this specific public, by providing professionals a range of scientific andpractical knowledge. It thus demonstrates the compatibility and direct applicability of research in the workplace.

Milieu où les ultrasons se propagent environ 10% plus rapidement qu’au sein des tissus environnants, le cristallin est connu pour être la source majeure d’aberrations de phase du milieu oculaire. De fait, l’échographie ophtalmique trans cornéenne est affectée par ses effets qui se manifestent sur les B-scans par une dégradation marquée de la résolution spatiale et du contraste, accompagnée de plus, d’importantes distorsions, particulièrement notables au niveau du fond de l’œil. Face à ce problème et en vue de l’arrivée prochaine de barrettes US HF dans la pratique ophtalmologique, un beamforming adapté a été développé au cours de cette thèse. Basé sur un lancer de rayon à 2 points fixes, il permet le calcul de délais de focalisation qui compensent les aberrations induites par le cristallin, en prenant en compte les effets réfractifs à son interface avec les humeurs. Les résultats obtenus in vitro et ex vivo avec une barrette 20MHz et un échographe de recherche (ECODERM) sont rapportés. / In ophthalmic ultrasonography the crystalline lens is known to be the main source of phase aberration, as ultrasounds (US) propagate about 10% faster than in the surrounding intra-ocular medium. Hence, it impairs significantly both spatial and contrast resolution of axial B-scans, and in addition causes important distortion, especially on the ocular fundus. To deal with this issue and in view of the next coming of US arrays in ophthalmologic practice, we developed in this thesis an adapted beamforming (BF) free from crystalline lens aberrations. It lies on a two point ray tracing approach to compute focusing delays that take into account crystalline lens aberrations including refraction at the interface. Initially developed considering a uniform US velocity in the lens, the adapted BF has been extended to consider the velocity gradient that exists in the real lens. In vitro and ex vivo results obtained with a 20 MHz linear array driven by a US research scanner (the ECODERM) are reported.

The aims of the research were twofold, namely, investigate challenges that hindered the implementation of inclusive education in Ethiopia and develop a framework that can enhance the inclusion of children with disabilities (CwDs). The ecology of human development has served as the theoretical lens underpinning this study to discover challenges that hindered the implementation of inclusive education. These barriers were also investigated from micro, meso, exo, and macro perspectives in the system. With this, I employed qualitative approach under the hegemony of constructivism paradigm. The hermeneutic design of the study enabled me to build knowledge about the barriers that hindered the implementation of inclusive education. Subsequently, using semi-structured interview and focus group discussion as instrument, I listened to experts in education, school supervisors, professionals in SNE and education vice heads. Thereafter, the data analysis went by transcribing the recorded interview verbatim. Then, using the transcribed and chunked data, I mapped the range and nature of phenomena, created typologies and found out associations between themes with a view to provide explanations for the findings. The process of mapping and interpretation was also guided by the original research aims as well as by the themes that have emerged from the data themselves. The participants revealed that the challenges to implement inclusive education ranged from the absence of mandatory national inclusive policy to the low income of the families of CwDs. Therefore, lack of collaboration among stakeholders of education, misconception of inclusive education, shortage of trained teachers, poor allocation of finance, poor school infrastructure and lack of mandatory inclusive policy were the few identified barriers among others. Finally, I have recommended collaborative effort among stakeholders to ensure inclusion of CwDs. / Inclusive Education / D. Phil.

The thesis is focused on the study of detection of QRS complex in time a frequency domain. The aim is to implement selected methods and their comparison to assess the effectiveness of QRS complex.

Let us consider the singularly perturbed model problem Lu := -epsilon laplace u-bu_x+cu = f with homogeneous Dirichlet boundary conditions on the unit-square (0,1)^2. Assuming that b > 0 is of order one, the small perturbation parameter 0 < epsilon << 1 causes boundary layers in the solution. In order to solve above problem numerically, it is beneficial to resolve these layers. On properly layer-adapted meshes we can apply finite element methods and observe convergence. We will consider standard Galerkin and stabilised FEM applied to above problem. Therein the polynomial order p will be usually greater then two, i.e. we will consider higher-order methods. Most of the analysis presented here is done in the standard energy norm. Nevertheless, the question arises: Is this the right norm for this kind of problem, especially if characteristic layers occur? We will address this question by looking into a balanced norm. Finally, a-posteriori error analysis is an important tool to construct adapted meshes iteratively by solving discrete problems, estimating the error and adjusting the mesh accordingly. We will present estimates on the Green’s function associated with L, that can be used to derive pointwise error estimators.
