CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / Dentro do atual contexto do trabalho, muitos trabalhadores tÃm sido afastados de seu exercÃcio profissional em decorrÃncia de adoecimento provocado pela prÃpria situaÃÃo de trabalho. Quando ocorre retornarem Ãs suas atividades laborais, apÃs o restabelecimento de sua saÃde, muitas vezes o fazem com restriÃÃes de sua capacidade de trabalho. O objetivo deste trabalho à apreender a experiÃncia dos atendentes quanto ao processo de trabalho-adoecimento por LER/DORT-reabilitaÃÃo. A pesquisa envolveu sete atendentes de um call center de uma empresa privada de telecomunicaÃÃes que atua no estado do CearÃ, entre os quais cinco apresentavam sintomas de LER/DORT e dois permaneciam saudÃveis, uma supervisora e um membro do sindicato da categoria. A tÃcnica utilizada foi a entrevista semi-estruturada. Os resultados encontrados revelaram que alguns aspectos do perfil do atendente sÃo semelhantes aos apresentados em outros estudos, como, por exemplo, a predominÃncia feminina com pouco mais de 70% e a preponderÃncia da terceirizaÃÃo como vÃnculo de trabalho. Quanto aos aspectos que diferiram estÃo a predominÃncia de atendentes com idade entre 18 e 22 anos e o nÃvel de escolaridade elevada. Neste caso, encontramos um nÃmero expressivo de atendentes matriculados em cursos superiores, o que significa que se trata de trabalhadores que ainda estÃo buscando maior qualificaÃÃo enquanto trabalham. Esses atendentes se defrontam com condiÃÃes de trabalho precÃrias, ritmos intensos de trabalho e cobranÃas excessivas por produtividade, o que maximiza suas chances de adquirir a LER/DORT. Somando-se a isso, nas situaÃÃes em que trabalhador adoece, a empresa tenta encobrir a relaÃÃo com a situaÃÃo de trabalho, negando-se a reconhecer o nexo causal entre os aspectos do trabalho e a doenÃa. Nos casos em que se reconhece o nexo causal, o atendente à encaminhado para tratamento e reabilitaÃÃo atravÃs do INSS. Quando este trabalhador retorna à empresa, em geral assume um posto de trabalho muito aquÃm de sua qualificaÃÃo por praticamente nÃo haver outra atividade que possa realizar sem riscos para o retorno dos sintomas de LER. Afora isto, uma vez findo seu perÃodo de estabilidade em razÃo do adoecimento, o atendente geralmente à demitido. Esses trabalhadores vivem, portanto, dois dilemas que os amedrontam: ao permanecer na empresa, sÃo forÃados a realizar atividades que consideram inÃteis e atà humilhantes, o que leva a sentirem-se discriminados por colegas e supervisores; ao serem demitidos, estarÃo no mercado de trabalho jà com sua capacidade de trabalho comprometida, antes mesmo de estarem totalmente qualificados, e tendo que concorrer com aqueles que sÃo considerados saudÃveis. / Each year a considerable number of workers are obliged to stop working due to work-related health problems. Those who manage to recover and resume their professional activities often do so under certain health restrictions. The objective of the present study was to look into the work-disease-rehabilitation process of workers afflicted with repetitive strain injury (RSI)/work-related musculoskeletal disorder (WRMD). Semistructured interviews were applied to seven operators at a private call center in Cearà (five of whom presented RSI/WRMD), one supervisor and one trade union representative. The findings show that our subjects share a number of characteristics with call center operators described in other studies on RSI/WRMD, such as the prevalence of female workers (>70%) and outsourced jobs. On the other hand, our subjects differed from most studies with regard to their age range (18-22 years) and schooling (relatively high level). Many of our subjects were taking courses at the university in order to improve their professional qualification while on the job. The poor working conditions, long hours and pressure for productivity placed our subjects at increased risk for acquiring RSI/WRMD. In general, when workers present work-related diseases, companies may deny the existence of a causal relationship. When such relationships are recognized workers are referred to treatment and rehabilitation through public health care (SUS). When rehabilitated workers return to their respective companies they are often given jobs below their actual skill level to prevent recurrence of RSI/WRMD. Once the period expires during which rehabilitated workers are protected against dismissal by law, many such workers are laid off. Thus, workers in this category are caught in a dilemma: if they remain on the job after their rehabilitation, they will have to perform activities they consider meaningless or even humiliating, while being discriminated by peers and supervisors, and if they decide return to the labor market, they will do so as recently rehabilitated and not yet fully trained.

The goal of this diploma work is aplication of technical analysis indicators, especially trend indicators and oscillators. Analysis was made for period of 5 years back on one title from foreign exchange market. Analysis indentifies whether are indicators more profitable than benchmark in the long term. Analysis also examine whether combination of indicators earn more, than indicators themselves.

Aujourd’hui, la durée d’exploitation de certaines structures en béton est amenée à être prolongée, en parallèle, des structures présentent prématurément des signes d’endommagements dû parfois à une mauvaise prise en compte des conditions environnementales. Assurer la durabilité des structures, c’est également assurer leur exploitation de façon sécuritaire, économique et écologique. Notre objectif est dans un premier temps de comprendre les phénomènes et mécanismes en jeu, ainsi que leur potentiels couplages ; puis, dans un deuxième temps, de créer des modèles prédictifs fiables de ces comportements.Le travail présenté s’intéresse en particulier aux structures nucléaires, qui en plus d’avoir un enjeu majeur, présentent des risques vis-à-vis de la dessiccation et de pathologies thermo-activées comme la réaction sulfatique interne (RSI). Plus précisément, l’objectif de cette thèse est de comprendre la participation des granulats dans les mécanismes de dégradation du matériau sous ces deux sollicitations respectives, puis leur couplage.A cet effet, une approche expérimentale multi-échelle est menée. Elle s’intéresse à l’évolution des déformations différées ainsi que des propriétés mécaniques et de transfert de matériaux cimentaires soumis soit à la dessiccation, soit à la RSI. Dans les deux cas, les paramètres influents des granulats dans les mécanismes ont été mis en évidence et une étude paramétrique a été mis en place afin de dégager clairement l’influence de ces paramètres.Dans un premier temps, l’étude de la dessiccation est basée sur le suivi et la caractérisation de sept formulations modèles ; i.e. dont les squelettes granulaires ont été contrôlés et sélectionnés selon la taille et la fraction volumique des granulats dans le matériau ; sur 200 jours. Les essais ont mis en évidence l’influence de ces paramètres dans le phénomène d’incompatibilités de déformations entre pâte de ciment et granulats. En parallèle, l’étude expérimentale de la réaction sulfatique interne s’intéresse à caractériser l’influence de la nature minéralogique des granulats sur la formation et la progression de la pathologie. Nous nous intéressons à l’influence de ce paramètre sur la cinétique et le taux de la réaction, mais également sur l’évolution des propriétés du matériau, afin d’identifier tous les mécanismes physico-chimiques présents. Enfin, une dernière étude s’intéresse au couplage entre RSI et dessiccation. Ici, les paramètres granulats ont été fixés, et des échantillons réactifs vis-à-vis de la RSI ont été soumis à des cycles de séchage-imbibition. / Today, the operating life of some concrete structures is likely to be extended, in parallel, structures show early signs of damage due sometimes to poor consideration of environmental conditions. Ensuring the sustainability of structures also means ensuring their safe, economical and ecological operation. Our objective is first to understand the phenomena and mechanisms at play, as well as their potential couplings; then, in a second step, to create reliable predictive models of these behaviours.The work presented is particularly interested in nuclear structures, which, in addition to having a major stake in our societies, present risks with regard to desiccation and thermo-activated pathologies such as the delayed ettringite formation (DEF). More precisely, the objective of this thesis is to understand the participation of aggregates in the degradation mechanisms of the material under these two respective stresses, and then their coupling.To this end, a multi-scale experimental approach is being conducted. It takes interest in the evolution of delayed deformations as well as the mechanical and transfer properties of cementitious materials subjected to either desiccation or DEF. In both cases, the influential parameters of the aggregates in the mechanisms were identified and a parametric study was carried out to clearly identify the influence of these parameters.First, the desiccation study is based on the monitoring and characterization of seven model formulations; i.e. granular skeletons were controlled and selected according to the size and volume fraction of the aggregates in the material; over 200 days. The tests revealed the influence of these parameters in the phenomenon of aggregate restraint.In parallel, the experimental study of DEF aims at characterizing the influence of the mineralogical nature of aggregates on the formation and progression of the pathology. We are interested in the influence of this parameter on the reaction kinetics and rate, but also on the evolution of the material properties, in order to identify all the physico-chemical mechanisms at stake. Finally, a final study is interested in the coupling between RSI and desiccation. Here, the aggregate parameters were set, and samples reactive to DEF were subjected to drying and soaking cycles.

Introduction: A successful return to sport (RTS) after anterior cruciate ligament reconstruction (ACL-R) demands optimal physical and psychological rehabilitation. Aim: Study the change in psychological readiness to RTS between three- and six-months post ACL-R, to associate psychological readiness to patient-reported knee function and identify factors associated to greater psychological readiness to RTS. The secondary aim was to examine how the Covid-19 pandemic has affected the patients’ rehabilitation. Methods: Prospective cohort study including patients with primary ACL-R recruited from the Swedish Knee Ligament register, age 16-40 and physically active on Tegner>3. Demographics including pre-injury sport participation, psychological readiness reported with the Anterior Cruciate Ligament-Return to Sport After Injury (ACL-RSI) scale, knee function reported with the subjective International Knee Documentation Committee (IKDC) and the impact on rehabilitation by Covid-19 were analyzed at three- and six-months post-surgery. ACL-RSI scores were compared, correlated to IKDC and univariate analysis was used to determine the association between factors and the psychological readiness to RTS. Results: 141 patients were analyzed (56 men, 85 women; median age 24 years), all were recreational or competitive athletes (median Tegner level 8). The psychological readiness progressed through rehabilitation, was correlated to subjective IKDC. No differences could be detected between ACL-RSI scores and included factors at six months post ACL-R. Covid-19 had an impact on 36% (40/112) of the patients’ rehabilitation. Conclusions: Psychological readiness improved after ACL-R and was significantly associated to self-reported knee function at six months post ACL-R. Covid-19 restrictions affected rehabilitation for one in every three participants.

Previous research has shown that the reactive paradigm is suitable for programming by voice, due to its frequent use of expressions used in common English. However, the software used in the previous research (Talon) does not support reactive programming. To our knowledge, no other programming-by-voice software has built-in support for RxJava. The main focus of this study is the development and testing of a vocal programming environment that recognizes RxJava operators and commands. This is done by writing custom scripts that form a RxJava-adapter for a software called Serenade. The purpose of the adapter is to determine to what degree customization can improve the programming-by-voice experience, in terms of reduced cognitive and vocal load. The testing process also reveals challenges related to programming-by-voice in reactive Java, as well as challenges related to creating custom voice commands for Serenade. The results indicate that Serenade is superior to Talon, requiring on average 45\% fewer words to produce the same code. When the default version of Serenade is compared to the custom version with custom voice commands, the improvement is 19\%. The study also concludes that there are many challenges facing speech recognition when used in a programming environment. The custom script feature in Serenade, while still having some limitations, is advanced and allows the user to create complex custom voice commands.

Cette étude examine la lecture des textes de théâtre comme des textes de fiction, visant à faire sortir ce genre de lecture du cadre de l’analyse textuelle au sein duquel on a tendance à l’enfermer. L’examen s’effectue à la lumière de l’interrogation sur le suicide dans le drame français du XIXe siècle : son objectif est de cerner l’effet que le suicide d’un personnage exerce sur le lecteur. Pour ce faire, nous nous servons du concept de lecteur virtuel, destinataire implicite et atemporel des effets du texte selon Vincent Jouve ; ce lecteur immerge au sein du monde possible de fiction soutenu par le dispositif qui se fonde sur la tripartition Réel - Symbolique - Imaginaire de Lacan.La réflexion est structurée en cinq parties : l’introduction théorique est suivie des analyses qui portent, respectivement, sur le mélodrame, le drame romantique, le drame naturaliste et le drame symboliste. En nous penchant sur l’effet du suicide fictionnel sur le lecteur, qui est systématiquement relié au questionnement de la catharsis, nous traitons également de l’évolution des formes et genres théâtraux évoqués dans l’optique de la lecture « virtuelle ». Ainsi, lire le drame français du XIXe siècle, c’est voyager de la certitude optimiste du mélodrame à l’indétermination tragique du drame symboliste, du suicide effectif aux morts probablement volontaires, de la catharsis « larmoyante » à l’anticatharsis... / This study examines the reading of drama texts as the reading of fictional texts, aiming to broaden the current approach according to which the reading of drama texts is mainly limited to text analysis. This question is examined in the light of the issue of suicide in 19th-century French drama. The principal aim of this study is therefore to understand the impact of the character’s suicide on the reader via the detailed analysis of the ins and outs of the suicidal act. The study applies Vincent Jouve’s concept of the virtual reader, who is defined as an implicit and atemporal recipient of the text effects. This reader emerges in a fictional world that is supported by an operative device (dispositif) based on the Lacanian triptych of the Real, the Symbolic and the Imaginary.The dissertation consists of five chapters. The theoretical discussion is followed by four chapters that deal, respectively, with melodrama, romantic drama, naturalist drama, and symbolist drama. In addition to the effect of the fictional suicide on the reader (which is systematically connected to the catharsis), the evolution of theatrical genres and forms is explored from the perspective of “virtual” reading. Thereby, the reading of 19th-century French drama could be viewed as a journey from the optimistic certainty of melodrama to the tragic indeterminacy of symbolist drama, from actual to probable suicides, from “sorrowful” catharsis to anticatharsis.

In this master thesis we investigate completeness theorems in the framework of abstract algebraic logic. Our main interest lies in the completeness with respect to the so called relatively (finitely) subdirectly irreducible models. Notable part of the presented theory concerns the difference between finitary and infinitary logical systems. We focus on the well-known fact that the completeness theorem with respect to relatively (finitely) subdirectly irreducible models can be proven in general for all finitary logics and we discuss the possible of generalizing this theorem even to infinitary logics. We show that there are two interesting inter- mediate properties between this completeness and finitarity, namely (completely) intersection-prime extension properties. Based on these notions we define five classes of logics and propose a new hierarchy of finitary and infinitary logics. As a main contribution of this dissertation we present an example of a logic separat- ing some of these classes. Keywords: Abstract algebraic logic, completeness, relatively (finitely) sub- directly irreducible models, RSI-completeness, RFSI-completeness, (completely) intersection-prime extension property, IPEP, CIPEP.

O objetivo da presente pesquisa foi identificar a ocorrência de Lesão por Esforço Repetitivo (LER) em Cirurgiões Dentistas (CDs) e os meios de prevenção e tratamento adotados. Trata-se de um estudo transversal com 127 CDs associados à Associação Paulista de Cirurgiões Dentistas/Regional de Ribeirão Preto (APCD/RP). Foi utilizado um questionário auto-aplicável abordando as temáticas relevantes para a identificação e compreensão do objeto de estudo. A amostra foi dividida em dois grupos, sendo o Grupo A composto por CDs acometidos por LER (48,05%) e o Grupo B pelos não acometidos (51,95%). Encontrou-se como região mais acometida pela LER, os ombros (27,8%), seguida pelas mãos (24,6%), quanto ao sexo houve predominância do feminino com 77%, e a especialidade onde mais ocorreu adoecimento foi a endodontia, com 70% dos endodontistas. Em relação às informações que os CDs têm à respeito da LER assim como da relação das práticas de atividade de trabalho desenvolvidas na Odontologia e o adoecimento por LER, observou-se que o profissional ainda desconhece a doença e sua relação com o exercício profissional, fator determinante para adotar práticas de prevenção. Os tratamentos adotados pelos CDs acometidos pela doença são em ordem decrescente, medicamentoso, fisioterápico, acupuntura e por práticas alternativas. Os resultados deste estudo confirmam e reforçam a necessidade de novas pesquisas e subsidiarão a elaboração de um manual de prevenção que será distribuído gratuitamente aos profissionais. / This study aimed to identify the occurrence of Repetitive Strain Injury (RSI) in dental surgeons and what means of prevention and treatment were adopted. We carried out a cross-sectional study, involving 127 dental surgeons (DS) associated to a regional association of dental surgeons (APCD/RP). A self-applied questionnaire was used, addressing relevant themes to identify and understand the study object. The sample was divided in 2 groups: Group A (48.05%) consisted of DS affected by RSI and Group B (51.95%) of professionals who were not. The most affected area was the shoulders (27.8%), followed by the hands (24.6%). RSI mainly attacked female professionals (77%) and endodontists (70%). As to the DS’ information about RSI and about the relation between dentistry activities and the disease, we found that these professionals are still unaware of RSI and its relation with professional activities, which would be a determinant factor to adopt preventive measures. Affected DS adopted the following treatments, in decreasing order: medication, physiotherapy, acupuncture and alternative practices. These results confirm and reinforce the need for further studies and will serve as foundations for the elaboration of a manual, to be distributed freely among these professionals.

Objetiva-se conhecer a experiência de adoecimento sob a ótica do ?corpo incapacitado? nas perspectivas fenomenológica, social e política, apoiando-se nos pressupostos da ?experiência de enfermidade? e nas ?narrativas da doença?. Para construir esses enredos, utilizou-se a ?análise temática? de entrevistas em profundidade com trabalhadores sob regime de benefício pela Previdência Social brasileira. A trama foi tecida partindo do auto-reconhecimento dos trabalhadores sobre sua condição antes do adoecimento, seguindo pelas percepções iniciais da incapacidade, bem como as estratégias mais incipientes de enfrentamento até ações mais pragmáticas de resistência, passando pelas construções metafóricas que apontam para processos legitimadores da invalidez. Sentidos e significados foram extraídos dessas experiências, denotando também processos macrossociais imbricados nos sentidos da vida prática, requerendo uma visão holística, dialeticamente integrada a estratégias que valorizem mais a abordagem intersubjetiva sobre a incapacidade em LER/Dort. / Salvador
