L’état de santé des personnes âgées se dégrade, les niveaux de dépendance s’accroissent, induisant de profondes conséquences sur l’organisation sanitaire en France. Les fractures du col du fémur illustrent ce défi au regard de leur fort impact sur la qualité de vie et sur la morbi-mortalité des patients. Notre étude quantitative et qualitative, (Jan. 2012 - Jan. 2013) au sein du principal service de chirurgie orthopédique d’Alsace, a permis de retracer le parcours de soin de 107 patients âgés de 75 ans et plus. Notre principale conclusion est que le patient n’a que très peu de place dans le processus décisionnel de son parcours de soin. Cela est d’autant plus dommageable que cette fracture revêt une double signification: physique (besoin d’assistance accrue) et symbolique (dépendance anticipée). Notre étude interactionniste permet de dégager des pistes d’actions opérationnelles dans les domaines sanitaires, politiques et éthiques afin de limiter les effets délétères de cette pathologie. / In a context of depressed health-conditions for elderly people, the levels of dependency are rising. It induces deep consequences for the entire health care organisation. For instance, the fractures of the femoral neck (FFN) represent a healthcare challenge regarding their strong impact on patients’ quality of life and on their morbity-mortality. We conducted a qualitative and quantitative study (Jan. 2012- Jan. 2013) within the main department of orthopedic surgery in Alsace in order to track the healthcare paths of 107 patients of 75 years-old or more. Our main conclusion is that patients are poorly involved in the decisions for their care. This is all the more harmful because the FFN is in fact dual. It is both a physical (higher assistance needed) and a symbolic (earlier dependency) breakage. Our interactionist study identifies areas for pragmatic actions in health-care, public policies and ethic that could contribute to absorb / reduce the pernicious effects of this pathology.

The specific objectives of this work are to analyze the ultramontane discourse present in the school practices of the college and to identify the influence of the institutional characteristics of the Congregation of the Daughters of Charity in the formation of the female youth. The educational received internal and external students and take cared of orphaned girls. The girls of Nossa Senhora das Dores were prepared to be good mothers, wives and educators. With respect to the pedagogical practices developed in the college, the present research proposes to investigate them using the qualitative method. As an instrument for conducting the research will be used documentary analysis and bibliographic survey. In order to do so, it is proposed to investigate the legal documents that have been institutionalized for the realization of this project both with regard to the laws of the State, as well as the laws of the Church and of the College itself. Therefore, the expected result of the research is to emphasize the importance of discussing the organization of female teaching and its attempt to systematize within the educational framework, using women as an instrument to expand this new discourse.

Ter acesso a documentos prim?rios da Inquisi??o, no inicio da forma??o territorial de Vila Rica viabilizou compreender mais a realidade do Santo Of?cio, os seus interesses e como atuavam, tendo em vista o car?ter m?ltiplo de julgador, controlador e repressor, atuando aparentemente como ide?rio da manuten??o da f? Cat?lica. Assim, selecionou-se Vila Rica, por se tratar de uma das principais Vilas no per?odo colonial do Brasil. Logo, houve delimita??o do espa?o e tempo; vale relatar que o principal expoente Inquisitorial em Vila Rica eram os Crist?os-Novos (1711-1750). / Disserta??o (Mestrado Profissional) ? Programa de P?s-Gradua??o em Tecnologia, Sa?de e Sociedade, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2017. / This work was developed through researches and contributions with the Inquisition and its Inquisitorial aspects, in the quest to abstract the actions of the Court of the Holy Office in Vila Rica - Minas Gerais, its developments and experiences in the first decades of the 18th century. Having access to primary documents of the Inquisition, at the beginning of the territorial formation of Vila Rica made it possible to understand more the reality of the Holy Office, its interests and how they acted, considering the multiple character of a judge, controller and repressor, apparently acting as maintenance of the Catholic faith. Thus, Vila Rica was selected because it is the main towns in the colonial period of Brazil. Therefore, there was delimitation of space and time; it is worth mentioning that the main Inquisitorial exponent in Vila Rica was the New-Christians (1711-1750).

Les fractures du fémur proximal de la personne âgée sont généralement fixées par des dispositifs d’ostéosynthèse. Pour les fractures particulières dites inter-trochantériennes, il est possible de fixer la fracture de manière intra-médullaire (à l’intérieur de l’os) ou de manière extra-médullaire (en dehors de l’os). Pour chaque type de traitement, les hôpitaux sont équipés des deux systèmes de fixation. Les différences de morphologie des individus impliquent l’existence de multiples références d’implants et donc de surcoûts en termes d’équipement. Dans ce travail de thèse, un implant original adaptable à la plupart des morphologies a été développé. Cet implant permettra non seulement d’offrir aux chirurgiens une souplesse au cours des interventions chirurgicales mais aussi de réduire de manière significative les stocks d’implants dans les hôpitaux. Le comportement mécanique de l’implant est étudié dans différents cas de fractures par deux approches complémentaires, une méthode numérique par Éléments Finis et une approche expérimentale mettant en oeuvre des techniques de stéréo-corrélation à partir d’images de caméras rapides. Les résultats des calculs numériques sont confrontés à ceux issus d’essais réalisés sur des fémurs synthétiques, puis cadavériques en laboratoire d’anatomie. Les comparaisons avec des implants existants montrent que ce nouveau concept d’implant permet une fixation plus stable des fragments osseux et une bonne compression du foyer de fracture. / Proximal femoral fractures in the elderly are generally fixed with osteosynthetic devices. For specific fractures called intertrochanteric, it is possible to fix the fracture in an intramedullary way (inside the bone) or in an extramedullary way (outside the bone). For each type of treatment, hospitals are equipped with the two fixing systems. The differences in physical characteristics between individuals imply the existence of multiple references implants and therefore additional costs in terms of equipment. In this thesis work,an original implant adaptable to most people has been developed. This implant will provide surgeons greater flexibility during surgery but also significantly reduce stocks implants in hospitals. The mechanical behavior of the implant is studied in different cases of fractures by two complementary approaches,a finite element analysis and an experimental study employing stereo-image correlation technique from images of high speed cameras. The results of the numerical calculation are compared with those derived from tests on synthetic femurs, then cadaver in anatomy laboratory. Comparisons with existing implants show that this new implant concept allows for a more stable fixation of bone fragments and a good compression of the fracture.

Thus, we investigated to try to understand the creation of the new man and the invention of new traditions to confirm the status of republican modernity in two schools in Natal, the Colegio Americano, a private one, and a standard model of school, Augusto Severo, which is a public one. As a basis we have the history of institutions to analyze, paying close attention to consider the use of imitation in cultural patrimony as well as the use of strategies to distinguish. The concept of ownership follows, for present purposes, their focus of study on observation of diverse and contrasting use of these cultural objects, texts, readings and ideas from research institutions. For analysis of the link which occurs within the school environment, in every period of its history, we used the concept of school culture as a set of rules and practices which define knowledge to teach and conduct the introject. A culture that incorporates the school to keep a set with other religious cultures, political and popular of its time and space. In this sense, the educational institutions which we studied while showing what kind of in this work by preparing cultures, codes, different practices, and specific individuals they have, they were in important locations to provide modern cultural appropriation as a strategy for educational innovation and a factor of rationality and efficiency which could be observed and controlled, so gradually the modern school education was organized to produce its own society. As a challenge of affirmation and incorporating diverse social experiences to produce the modern, civilized man of the Republican time, the school, as part of the social life, which is singular in its practices, not only the set of reforms, decrees, laws and projects, but also as expressions of concept about life and society in terms of material, symbolic and cultural symbols in the social context in modernization. We focused on these two schools, because inside the wide cultural and material status of the city, they were the first republic schools which had the goal of having men and woman together culturally , with a view to adapting them to the modern movement to make them civilized / educated / rational . On this view, we would emphasize that this statement needs a reinvention as a new way through what is made at the schools which production of new spaces, practices, rites and what represents school, making and expressing a new identity, modern, different of the old symbols of the Empire. For this, nothing better than the organization of schooling, emphasizing on educating the individual and his/her responsibilities with the order and progress. We need to understand the past as a result of conflicts, including strengths and limitations within the historical and social context, and the invention of tradition as a process of formalization and ritualization of acts which want to perpetuate, as a reference to a group identity. These are practices and social educative representations which support the understanding of pedagogical and educational ideas at this historical moment, making a new way of being and doing in the Republican universe / Nossa pesquisa prioriza a an?lise das institui??es de ensino prim?rio na chamada Primeira Rep?blica em Natal/RN, enquanto inst?ncias privilegiadas na forma??o, divulga??o e cria??o da identidade nacional republicana e suas tradi??es. Assim, buscamos investigar e compreender a cria??o do homem novo e a inven??o de novas tradi??es para confirmarem o status de modernidade republicana dentro de duas institui??es escolares na cidade do Natal, o Col?gio Americano (de iniciativa privada) e o grupo escolar modelo, Augusto Severo (p?blica). Temos como base de an?lise a Hist?ria das institui??es, tendo o cuidado de considerar a imita??o do uso de bens culturais bem como o uso de estrat?gias de distin??o. A no??o de apropria??o segue, para fins deste trabalho, seu foco de estudo na observa??o do emprego diverso e contrastante dos mesmos bens culturais, textos, leituras e id?ias das institui??es pesquisadas. Para an?lise das rela??es que ocorrem dentro do ambiente escolar, em cada per?odo de sua hist?ria, utilizamos o conceito de cultura escolar, enquanto um conjunto de normas e pr?ticas que definem conhecimentos a ensinar e condutas a introjetar. Uma cultura que incorpora o fazer escolar, mantendo um conjunto com outras culturas religiosas, pol?ticas e populares de seu tempo e espa?o. Nesse sentido, as institui??es educativas estudadas neste trabalho, ao disporem de culturas, c?digos, pr?ticas diferenciadas, singulares e espec?ficas, constitu?ram-se em locais privilegiados para se darem apropria??es culturais modernas, como estrat?gia de inova??o educacional e fator de racionalidade e efici?ncias, observ?veis e control?veis. Paulatinamente, a educa??o escolar moderna, se organizava ao produzir a pr?pria sociedade. No desafio da afirma??o e incorpora??o de diversas experi?ncias sociais para produzir o homem republicano moderno e civilizado, a escola, como parte do social, singularizava em suas pr?ticas, n?o somente o conjunto de reformas, decretos, leis e projetos, mas express?es de concep??es de sociedade e vida no plano material, simb?lico e cultural, no contexto social em moderniza??o. Detemo-nos nessas duas institui??es porque dentro do diverso estado material e cultural da cidade foram as primeiras escolas republicanas que objetivavam homogeneizar culturalmente homens e mulheres na perspectiva de adequ?-los ao movimento da modernidade para faz?-los civilizados/educados/racionais. Sobre esse prisma conv?m destacar que essa reinven??o necessita de uma afirma??o como nova forma escolar atrav?s da produ??o de novos espa?os, pr?ticas, ritos e s?mbolos escolares, produzindo e expressando uma nova identidade, o moderno, contr?rio aos s?mbolos ultrapassados do Imp?rio. Para tanto, nada melhor do que a organiza??o da instru??o escolar, com ?nfase na forma??o do indiv?duo, e suas responsabilidades com a ordem e o progresso. ? entendermos o passado como resultado dos conflitos, com suas potencialidades e limites dentro do contexto hist?rico e social e a inven??o de tradi??es enquanto processo de formaliza??o e ritualiza??o de atos que se quer perpetuar como refer?ncia de identidade a um grupo. S?o essas pr?ticas e as representa??es s?cio-educativas que favoreceram a compreens?o das id?ias pedag?gico-educacionais nesse momento hist?rico, destinadas a formar um novo modo de ser e fazer no universo republicano

Entre as t?cnicas existentes, os controladores fuzzy destacam-se pela sua capacidade de tratar de severas n?o linearidades presentes em plantas reais e por conseguir representar o conhecimento especialista, que ? impreciso e inexato matematicamente. Este trabalho estudou dois tipos de controladores fuzzy existentes, baseados no modelo Sugeno, sendo fuzzy tipo-1, aqui classificado como fuzzy convencional, e o fuzzy tipo-2. Devido a complexidade em sintonizar controladores fuzzy que apresentam uma grande quantidade de par?metros, esse trabalho se prop?e a testar diferentes m?todos de otimiza??o meta-heur?sticos para a sintonia de controladores. Para validar os controladores obtidos foi utilizado um servo motor-DC da Quanser, um problema de controle que requer precis?o e velocidade na corre??o do erro de segmento da refer?ncia. Com o intuito de comparar o comportamento dos controladores, otimizou-se um controlador PI para cada um dos sistemas. Para quantificar e qualificar cada controlador foram utilizados tr?s ?ndices de avalia??o, ITEA, IEA e o ?ndice de Goodhart, este ?ltimo utilizado por levar em considera??o tamb?m o sinal de controle aplicado na planta. Pela an?lise dos resultados obtidos, o controlador fuzzy tipo-2 apresentou ganho significativo para o controle dessa planta, quando otimizado com o m?todo PSO. Pelos resultados, pode-se tamb?m inferir que o algoritmo das formigas n?o mostrou-se adequado para esse problema, com a fun??o de avalia??o proposta. / Differents stategies and control algorithms are already tested and registered by industry. Among the existing techniques, fuzzy controllers stand out for their ability to deal with nonlinearities present in real plants. Another fuzzy also allows to best represent expert knowledge, which is mathematically inaccurate. This proposal studied the two types of fuzzy controllers, based on Sugeno Model, the fuzzy type-1 is classified as conventional fuzzy and fuzzy type-2. In this study is used optimization techniques seeking to tune controllers in order to solve one of the biggest problem in fuzzy logic, its tunning. Ant colony, particle swarm and genetic algorithm are used and evaluated to this problem. A servo motor-dc is used to validate fuzzys controllers and pi controller obtained by optimization tecniques. In order to quantify and qualify each controller, three indices were used IEA, ITEA and Goodhart index. The results obtained prove that the type-2 fuzzy controller presented significant gain for the control of this plant, when optimized with the PSO method. From the results, it can also be inferred that the ant algorithm was not adequate for this problem, with the proposed evaluation function.

Le cancer du col de l’utérus est le troisième cancer le plus fréquent chez la femme, dont l’agent étiologique majeur est l’infection par les papillomavirus humain (notamment HPV-16 et 18), qui sont de petits virus infectant les épithéliums muqueux et cutanés, et pouvant induire la formation de tumeurs. L’inducteur majeur du processus oncogène est le processus d’intégration des régions codantes pour les oncoprotéines E6 et E7, au sein de la cellule hôte suite à l’infection. Elles interférent avec le cycle cellulaire et induisent notamment l’immortalisation, voire la transformation des cellules. Les fonctions les plus connue de ces deux oncoprotéines sont la dégradation des suppresseurs de tumeur p53 et pRb, respectivement. Mon travail de thèse à consisté en la mise au point des vecteurs adénoviraux exprimant des miARN dirigés contre l’oncoprotéine E6. Exprimés in vitro ils induisent l’induction de la mort cellulaire par apoptose des cellules tumorales traitées, via l’activation de la voie de caspases, et in vivo permettent le ralentissement de la croissance de tumeurs xénogreffées à des souris Nude. De plus, la stratégie thérapeutique adénovirale a montré ses extensions possibles sur d’autres types de cancers HPV-positifs, mais également via l’expression de différentes moléculaires thérapeutiques, visant à empêcher l’interaction des oncoprotéines telles qu’E6 avec leurs partenaires cellulaires et ainsi les empêcher d’exercer les activités biologiques impliquées dans le développement de cancers. Pour finir, les adénovirus peuvent également être vu comme des outils d’extinction fonctionnels d’E6 et permettant d’étudier les répercutions sur d’autres processus cellulaires. / Cervical cancer is the third most common female cancer. Infection by human papillomavirus (mainly HPV-16 and 18), with tropisms for mucosal or cutaneous squamous surfaces, is the major etiological agent implicated in cancer and tumor development. After infection, the oncogenic process is triggered by integration of oncoproteins E6 and E7 coding regions into the host cell genome. After integration, these oncoproteins interfere with the cell cycle and induce immortalization and cellular transformation of normal cells. The best known function of these two oncoproteins is the degradation of tumors suppressors p53 and pRb respectively. My thesis project consisted in the development of adenoviral vectors expressing miRNA directed against E6 oncoprotein. Their in vitro expression resulted in cellular death by apoptosis of the treated tumor cells, and allowed reduction of tumor growth in vivo in nude mice xenografts. In addition, the adenoviral therapeutical strategy showed its possible extensions on other types of HPV-positive cancers, but also through the possible expression of different therapeutic molecules aimed at preventing the interaction of viral oncoproteins, such as E6, with their cellular partners. These abolished interactions prevent oncoproteins from exercising their biological activities implicated in the development of cancers. In conclusion, we can say that adenoviruses can also be seen as functional tools suppressing E6 and enabling to highlight the repercussions of its suppression on other cellular processes.
