Implementace procesu Configuration management / Configuration management process implementation

Šipka, Ladislav January 2010 (has links)
The aim of this Thesis is to describe the practical implementation of process management in terms of Configuration Management process and subsequent implementation support tool, configuration and management database, focusing on describing and identifying particular steps needed for the definition and implementation process and the subsequent selection and implementation support tools. As an initial base of this Thesis I have used the practical experience of projects focusing on the definition and implementation of process management and subsequent implementation support tools, in which I acted in the role of the Configuration Manager. It means I assisted at course of entire projects. The Thesis focuses mainly on my run and defined Configuration Management process and describes the process and importance of various activities leading to the successful establishment of a process into practice, including identified problems and some of their solutions. The result of this Thesis should approach introducing one of the process of family ITIL v. 2 to practice and subsequent leading to the selection and implementation of the configuration and management database, as a major output of this process.

Estudo da interação endotélio-matriz extracelular no remodelamento da pele observado no modelo experimental de esclerodermia e na enfermidade espontânea humana / Study of endothelium-extracellular matrix interaction in skin remodeling observed in an experimental model of scleroderma and spontaneous human disease

Introdução: A imunização de coelhos saudáveis com colágeno do tipo V (COLV) reproduz as principais manifestações da esclerose sistêmica (ES), incluindo fibrose, vasculopatia e produção de autoanticorpos específicos da doença. Estudos preliminares mostraram que, tanto na derme de animais imunizados com COLV (COLV-IM), como na derme de pacientes com ES, observa-se deposição aumentada de COLV anômalo, mas não se sabe qual a relevância clínica deste achado. O remodelamento da matriz extracelular é precoce nos animais COLV-IM, ocorrendo já no sétimo dia após a imunização, o que sugere que o COLV esteja relacionado com a injúria endotelial, evento primário envolvido na patogênese da ES. Desta forma, os objetivos do presente estudo foram avaliar a expressão de COLV na derme de controles saudáveis e de pacientes com ES e sua correlação com espessamento cutâneo, atividade e duração da doença; assim como pesquisar uma possível associação entre a deposição deste colágeno na derme com a expressão de marcadores de apoptose e de ativação endotelial em pacientes e no modelo animal induzido pela imunização com COLV. Pacientes e Métodos: Biópsias de pele de pacientes com ES (N=18, 6 com doença precoce e 12 com doença tardia) e de controles (N=10) pareados por idade e sexo, assim como biópsias de pele de coelhos imunizados com COLV + adjuvante de Freund (COV-IM, N=6) ou adjuvante de Freund (N=6) foram avaliadas. Nos pacientes com ES, o espessamento cutâneo foi avaliado por meio do escore de Rodnan Modificado (MRSS) e a atividade da doença foi calculada pelo índice de atividade de Valentini. Para realizar a quantificação por histomorfometria, o COLV na derme foi identificado por imunofluorescência. Caspase-3, endotelina-1, CTGF, TGF e VEGF nas células endoteliais dérmicas foram marcados por imunohistoquímica. Nos pacientes e nos controles, o COLV proveniente da cultura de fibroblastos dérmicos foi quantificado por PCR RT em tempo real e caracterizado por eletroforese, imunoblotting e reconstrução tridimensional, por meio da microscopia confocal. Resultados: O depósito de COLV foi maior na derme de pacientes com doença precoce, quando comparados aos controles e aos pacientes com doença tardia. A atividade e a duração da ES estiveram associadas com o depósito de COLV. A expressão de RNA mensageiro das cadeias COLV1 COLV2 foi aumentada em relação aos controles e a reconstrução tridimensional confirmou a presença de fibras anômalas de COLV. Observou-se maior expressão de caspase-3, endotelina-1, CTGF, TGF e VEGF nas células endoteliais dos pacientes com ES, quando comparados aos controles. Houve correlação positiva entre o depósito de COLV e a expressão de caspase-3, endotelina-1 e CTGF. Ao comparar-se os coelhos COLV-IM com os controles, observou-se aumento significativo da expressão de COLV aos 7 dias e de endotelina-1 aos 210 dias após a imunização. Embora de maneira não significativa, verificou-se maior expressão de caspase-3, CTGF e VEGF nos animais COLV-IM e, quando os animais foram comparados ao longo do tempo, percebeu-se maior expressão de COLV no sétimo dia após a imunização na derme dos animais COLV-IM, diminuindo no trigésimo dia e voltando a subir aos 75 dias e aos 210 dias. A caspase-3 e a endotelina-1 comportaram-se de maneira semelhante. Conclusão: Estes resultados sugerem que o COLV possa agir como um possível gatilho envolvido na patogênese da ES, agindo como um indutor de ativação e de apoptose endotelial, que por sua vez poderia resultar em maior expressão de COLV, perpetuando o processo de remodelamento observado na pele dos pacientes com ES / Introduction: The immunization of healthy rabbits with type V collagen (COLV) reproduces the main characteristics of systemic sclerosis (SSc), such as fibrosis, vasculopathy and specific auto-antibodies. Preliminary studies demonstrated that both COLV-immunized rabbits (COLV-IM) and SSc patients exhibit increased expression of abnormal COLV in the dermis, but the clinical relevance of this finding is unknown. The remodeling of the extracellular matrix is an early event in COLV-IM rabbits that can be detected by the seventh day after immunization; this observation suggests that COLV is involved in endothelial injury, one of the first manifestations of the disease. Thus, the objectives of this study were to evaluate COLV expression in the dermis of healthy controls and SSc patients and to determine the correlation of this expression with skin thickness, disease activity and duration and search for a possible association between this collagen with apoptosis and activation of endothelial cells markers in patients and in animal model induced by immunization with COLV. Patients and Methods: Skin biopsies from 18 patients (6 early-stage and 12 late-stage) and 10 healthy controls as well as skin biopsies from rabbits immunized with COLV (COLV-IM) and Freund adjuvant (N=6) or Freund adjuvant alone (N=6) were evaluated. Skin thickening assessment was performed with the Modified Rodnan Skin Score (MRSS), and activity was calculated using the Valentini Disease Activity Index. To perform quantification by histomorphometry, COLV was identified by immunofluorescence, and caspase-3, endothelin-1, CTGF, TGF and VEGF in dermal endothelial cells were labeled by immunohistochemistry. In SSc patients and healthy controls, COLV from dermal fibroblast culture was quantified by real-time RT-PCR and characterized by electrophoresis, immunoblotting and tridimensional reconstruction by confocal microscopy. Results: COLV deposition was increased in the dermis of the patients with early disease compared with the healthy controls and the patients with late disease. SSc activity and disease duration were associated with dermal COLV deposition. COLV1 and COLV2 mRNA expression levels were higher in SSc, and a tridimensional reconstruction of SSc dermal heterotypic fibers confirmed the presence of abnormal COLV. The dermal endothelial cell expression of caspase-3, endothelin-1, CTGF, TGF and VEGF was higher in the SSc patients than in the controls. There was a positive correlation between COLV deposition and caspase-3, endothelin-1 and CTGF expression. When the COLV-IM rabbits were compared with the controls, there was a significant increase in the expression of COLV 7 days after the immunization and a significant increase in the expression of endothelin-1 210 days after the immunization. The expression of caspase-3, CTGF and VEGF was higher in the COLV-IM animals than in the control rabbits, although not significantly, and when the rabbits were compared over time, the expression of COLV was higher in the dermis of the COLV-IM animals 7 days after immunization, decreasing at 30 days and increasing again at 75 and 210 days. Caspase-3 and endothelin-1 exhibited similar behavior. Conclusion: these results suggest that COLV can be a possible trigger involved in the pathogenesis of SSc, acting as an inducer of endothelial apoptosis and activation that could result in higher expression of COLV, perpetuating the remodeling process observed in SSc skin

NÁPRAVNÍKOVÁ, Veronika January 2016 (has links)
The thesis deals with the application of creative methods and forms of work during reading and literature lessons in the 2nd and 3rd grades of elementary school. The main focus is on good orientation in contemporary professional literature, alternative textbooks and methodical guides. The thesis is divided into a theoretical and a practical part. The theoretical part presents teaching of reading from the pedagogical-psychological point of view, it focuses on didactical-methodical aspects, on the problem of intensification of teaching in reading and literature lessons possibilities of modernization, optimization, rationalization and efficiency. In the practical part I introduce interesting methods and forms of work, new unconventional model approaches and effective methodical management of the teaching process. The thesis is enriched with attractive techniques for practising and deepening one's knowledge. In this way, the practical part offers a collection of playful forms of work which can be used during reading and literature lessons. Some games are verified in practice.

Homologação para o reconhecimento ou execução da sentença arbitral estrangeira no Brasil: exceção de ofensa à ordem pública / Homologation for the recognition or enforcement of foreign arbitral award in Brazil: exception given to public policy offenses

Barros, Vera Cecilia Monteiro de 07 June 2013 (has links)
Esta dissertação analisa a exceção de ofensa à ordem pública como causa de recusa do reconhecimento e/ou execução da sentença arbitral estrangeira. Busca-se inicialmente determinar o conceito de ordem pública e sua extensão. Antes disso, contudo, elabora-se um breve panorama sobre sentença estrangeira e arbitragem comercial internacional, faz-se um apanhado histórico da homologação de sentença estrangeira no Brasil, analisa-se os aspectos gerais da homologação de sentenças arbitrais estrangeiras, as normas de origem interna e os tratados internacionais com vigência no Brasil, o procedimento homologatório e os pressupostos positivos e negativos da homologação. Após, analisa-se a ordem pública interna, internacional e transnacional, assim como a ordem pública processual e material. Em seguida, examina-se a extensão que a doutrina e a jurisprudência têm conferido ao conceito de ordem pública de que trata o art. V (2) (b) da Convenção de Nova Iorque e o art. 39, II da Lei nº. 9.307/96. Posteriormente, analisa-se alguns temas que já suscitaram questionamentos de ofensa à ordem pública, os casos já julgados pelo STF e STJ de homologação de sentenças arbitrais estrangeiras com alegação de ofensa à ordem pública e como o posicionamento do Judiciário, sob o enfoque da Análise Econômica do Direito, afeta os custos de transação dos negócios comerciais. Defende-se ao final do trabalho a necessidade de se restringir o campo de aplicação e o alcance dos questionamentos de ofensa à ordem pública. O objetivo do estudo é demonstrar que a ordem pública deve ser interpretada restritivamente e que a intervenção deve ser excepcional. / This Masters degree thesis analyzes the exception given to public policy offenses as a cause for the refusal of recognition and/or enforcement of foreign arbitral awards. This research initially attempts to define the concept of public policy and its extension. Prior to that, however, a brief analysis of foreign awards and international commercial arbitration as well as a historical overview of homologation in Brazil are drawn, and the general aspects of the recognition of foreign arbitral awards and the internal rules and international treaties which are effective in Brazil, the homologation proceeding itself, and both the positive and negative aspects of homologations are analyzed. Afterwards, the domestic, international and transnational public policies are analyzed, as well as the procedural and material public policy. Following, the meaning that the doctrine and jurisprudence have given to the concept of public policy presented in the Article V (2) (b) of the New York Convention, and in the Article 39 of Law No. II. 9.307/96 is examined. Later, some issues that have raised questionings related to public policy offenses are analyzed, as well as the cases already ruled by the Brazilian Supreme Court and the Superior Court of Justice for the homologation of foreign arbitral awards with alleged public order offenses and how the position of the judiciary, from the perspective of Economic Analysis of Law, affects transaction costs of business affairs. Finally, the need to limit both the scope of applications and the range of questionings concerning public policy offenses is defended. The main goal of this study is to demonstrate that public policy shall be strictly interpreted and that intervention must be exceptional.
