Proposal of methodology for project implementation fast-track in the consulting of hydrocarbons industry

En el desarrollo de la gestión de proyectos, en la actualidad, la velocidad de ejecución y la flexibilidad cada vez toman más importancia, pero ¿por qué?; la principal razón es la reducción de costos y la obtención de beneficios intangibles en cuanto a ventaja competitiva que se consigue con la disminución de tiempos, en contraste, si la reducción se da mediante un crashing, los recursos adicionales generaran un costo mayor para el proyecto, así que hay que encontrar un equilibrio entre estos dos ítems, debe tenerse claramente estipulado el enfoque y así establecer las prioridades para comenzar con la planificación del proyecto, estableciendo las tareas, el orden en que deben realizarse y sus interrelaciones para llevar a feliz término el proyecto. Posteriormente se ejecuta el proyecto, mediante la conformación de un equipo de trabajo se llevan a cabo las actividades para cumplir con los entregables y brindar un producto final al cliente, que cumpla con sus requerimientos en términos de tiempo, precio, seguridad, calidad y demás factores que permitan que se sienta satisfecho y además que pueda recibir un valor agregado que provoque que genere buena reputación y retorne para hacer negocios. Finalmente, al terminar cada proyecto, la empresa debe estar en capacidad de realizar un proceso de aprendizaje, tanto de las victorias como de los inconvenientes que se presentan en cada proyecto, así como un análisis de causalidad de estas ocurrencias, todo esto con el objetivo de propender a una mejora continua que es el objetivo de este artículo.In developing project management, today, the execution speed and flexibility are increasingly taking importance, but why ?; the main reason is the reduction of costs and intangible benefits obtained in terms of competitive advantage achieved with decreasing times, in contrast, if the reduction is given by a project crashing, additional resources will generate a higher cost for the project , so must to find a balance between these two items, it should be clearly stated focus and set priorities and to begin planning the project, setting out the tasks, in order to be performed and their relations to reach a successful completion the project. Subsequently the project is executed, through the formation of a work team carried out activities to comply deliverables and provide a final product to the customer that meets their requirements in terms of time, price, safety, quality and other factors that allows to feel satisfied and also receive added value that generates good reputation and return to do business. Finally, at the end of each project, the company should be able to perform a learning process for both the victories and the drawbacks that emerges in each project, and an analysis of causality of these occurrences, with the objective of tending to continuous improvement which is the objective of this article

How Does the Law Put a Historical Analogy to Work?: Defining the Imposition of “A Condition Analogous to That of a Slave” in Modern Brazil

Over the last decades, the Brazilian state has engaged in concerted legal efforts to identify and prosecute cases of what officials refer to as “slave labor” (trabalho escravo). At a conceptual level, the campaign has paired the constitutional protection of human dignity and the “social value of labor” with an expansive interpretation of the offense described in Article 149 of the Criminal Code as “the reduction of a person to a condition analogous to that of a slave.” At the operational level, mobile teams of inspectors and prosecutors have intervened in thousands of work sites, and labor prosecutors have obtained hundreds of consent agreements and convictions in the labor courts, a civil branch of the judiciary. Between the mid-1990s and the end of 2016, some 51,000 workers were administratively resgatados (“rescued”) from rural and urban workplaces in which inspectors determined that they had been reduced to a condition analogous to slavery. Under the supervision of the inspectors, labor contracts have been administratively cancelled, back pay has been (when possible) extracted from the employer, and unemployment insurance payments have been provided to the rescued workers

Lack of Association between BRAF Mutation and MAPK ERK Activation in Melanocytic Nevi

The mitogen-activated protein kinase (MAPK) extracellular signal-regulated kinase signaling pathway can be activated through mutations of V-RAF murine sarcoma viral oncogene homolog B1 (BRAF) oncogene, frequently found in melanoma (60%), common nevi (CN) (73–82%), and atypical nevi (AN) (52–80%). MAPK activation has been reported between 0 and 22% in nevi, and 86% of primary melanoma, without any knowledge of BRAF mutational status. We studied the correlation of MAPK activation status, BRAF mutation, and B-Raf expression in CN, AN, and melanoma. Using immunohistochemistry, phosphorylated (active) MAPK and B-Raf expression was studied in 24 CN, 21 AN, and 26 primary cutaneous melanomas (PM). BRAF mutations at codon 600 were assessed by PCR-RFLP. Active MAPK was detected in 29% of CN, 48% of AN, and 85% of PM. BRAF mutation was found in 67% of CN, 62% of AN, and 58% of PM. In all, 23% of CN, 54% of AN, and 93% of PM with BRAF mutation have activated MAPK. All lesions expressed B-Raf. BRAF mutation does not seem to be sufficient to produce MAPK activation in melanocytic nevi, and it is suggested that other events are needed to induce MAPK activation, that is, B-Raf overexpression, inhibition of MAPK phosphatases, or suppression of RAF kinase inhibitors

A influência histórica dos afluentes na água e sedimento do Delta do Jacuí, RS, Brasil

The high population density in a metropolis leads to socio-environmental impacts that directly affect local water resources. This work evaluated the historical data (between 2000 and 2014) of water and sediment monitoring in the Jacuí’s Delta region and analyzed the relationship between these sites. Seven monitoring sites around the Jacuí's Delta were evaluated: the outflow of the rivers Jacuí, Caí, Sinos, and Gravataí; the channels Ilha da Pintada and Navegantes; and Lake Guaíba. Water data were evaluated for: air and water temperature; depth; pH; electrical conductivity; transparency; turbidity; dissolved oxygen; biochemical oxygen demand; phosphorus; nitrogen; total residues; and escherichia coli. Sediment were evaluated for pseudo-total concentrations of metals (Al, Fe, Ca, Mn, Ba, V, Zn, Cu, Pb, Cr, Ni, Co, Li, Be, Cd, Hg, As, and Ag). The quality of water and sediment in the Jacuí's Delta are linked with the tributaries and priority flows of the channels. The historical data of water and sediment around the Jacuí's Delta shows the influence of the tributaries with low quality in the downstream points. The pollution of the rivers Caí, Sinos, and Gravataí negatively affects the environmental quality of the channel Navegantes and Lake Guaíba (catchment points to water supply). The water in those sites presents reductions in dissolved oxygen and high values of coliforms, and the sediment shows high concentrations of metal Zn, Pb, Cr, and Hg. Despite the reduction in Pb and Hg values in the sediment over the past years, pollution from the tributary rivers still persists.A grande densidade populacional nas metrópoles gera impactos socioambientais que afetam diretamente os recursos hídricos locais. O objetivo deste trabalho foi avaliar os dados históricos (entre 2000 e 2014) de monitoramento de água e sedimentos na região Delta de Jacuí e analisar a relação entre esses locais. Foram avaliados sete locais de monitoramento entorno do Delta de Jacuí: foz dos rios Jacuí, Caí, Sinos e Gravataí; canais Ilha da Pintada e Navegantes; e Lago Guaíba. Os dados de água foram avaliados para: temperatura do ar e da água; profundidade; pH; condutividade elétrica; transparência; turbidez; oxigênio dissolvido; demanda bioquímica de oxigênio; fósforo; nitrogênio; resíduos totais; e escherichia coli. Os sedimentos foram avaliados para concentrações pseudo-totais de metais (Al, Fe, Ca, Mn, Ba, V, Zn, Cu, Pb, Cr, Ni, Co, Li, Be, Cd, Hg, As e Ag). A qualidade da água e dos sedimentos no delta de Jacuí está ligada aos afluentes e fluxos prioritários dos canais. Os dados históricos de água e sedimentos no Delta de Jacuí mostram a influência dos afluentes com baixa qualidade nos pontos a jusante. A poluição dos rios Caí, Sinos e Gravataí afeta negativamente a qualidade ambiental do canal Navegantes e do Lago Guaíba (pontos de captação para abastecimento hídrico). A água nesses locais apresenta reduções no oxigênio dissolvido e grandes valores de coliformes e o sedimento apresenta grandes concentrações dos metais Zn, Pb, Cr e Hg. Apesar da redução ao longo dos anos nos valores de Pb e Hg no sedimento, a poluição dos rios tributários ainda persiste

Um portal de banco de imagens médicas distrubuído usando corba para integração de serviços de teleradiologia

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Ciência da Computação.A área do diagnóstico por imagem é um dos campos da medicina mais propensos a uso da Telemedicina, porque normalmente não existe a obrigação do contato direto com o paciente pelo radiologista responsável durante a elaboração do diagnóstico. A carência de especialistas em locais distantes de grandes centros urbanos faz da Telemedicina uma importante ferramenta para melhorar os serviços de atenção à saúde. Neste trabalho é apresentado um modelo baseado em uma abordagem federada chamo Portal de Teleradiologia, para a integração de bancos de imagens médicas DICOM distribuído geograficamente. O objetivo é prover uma visão única e transparente dos dados compartilhados sem sacrificar a autonomia dos sistemas integrantes ou interferir com operações locais. Um requisito obrigatório para sistemas desta natureza é a garantia de um contexto seguro para a execução das operações. O modelo proposto prevê também a identificação única de pacientes entre as diversas bases de dados através de técnicas de relacionamento de registros. Para a implementação do protótipo do sistema foi utilizada a tecnologia de objetos distribuídos através da arquitetura CORBA

The Impact of Contingency Management on Quality of Life Among Cocaine Abusers With and Without Alcohol Dependence

The use of quality of life measures (QOL) in substance abuse treatment research is important because it may lead to a broader understanding of patients’ health status and effects of interventions. Despite the high rates of comorbid cocaine and alcohol use disorders, little is known about the QOL of this population, and even less about the impact of an efficacious behavioral treatment, contingency management (CM), on QOL. In this study, data from three clinical trials were retrospectively analyzed to examine QOL in outpatient cocaine abusers with and without alcohol dependence (AD) and the impact of CM on QOL over time as a function of AD status. Patients were randomized to standard care (n = 115) or standard care plus CM (n = 278) for 12 weeks. QOL was assessed at baseline and Months 1, 3, 6, and 9. At treatment initiation, AD patients had lower QOL total scores and they scored lower on several subscale scores than those without AD. CM treatment was associated with improvement in QOL regardless of AD status. These data suggest that CM produces benefits that go beyond substance abuse outcomes, and they support the use of QOL indices to capture information related to treatment outcomes
