    Disserta√ß√£o (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnol√≥gico. Programa de P√≥s-Gradua√ß√£o em Engenharia de Produ√ß√£o.Este trabalho apresenta os resultados de um estudo realizado para comprovar a import√Ęncia da cultura organizacional como fator de influ√™ncia nos processos de implanta√ß√£o de sistemas de informa√ß√£o em empresas privadas. Nos modelos de Cultura Organizacional, os processos de mudan√ßa essenciais para a sobreviv√™ncia das organiza√ß√Ķes contempor√Ęneas provocam, nos indiv√≠duos, as mais variadas rea√ß√Ķes. Entre elas, destaca-se a resist√™ncia humana, capaz de influenciar decisivamente os rumos da mudan√ßa. Assim, considerando a relev√Ęncia do tema, procura-se identificar e analisar as principais causas de resist√™ncia √† mudan√ßa. S√£o considerados os conceitos e recursos empregados pelas empresas, na √°rea de sua cultura organizacional, em quatro estados da regi√£o amaz√īnica e a sua import√Ęncia na abrang√™ncia mercadol√≥gica das empresas pesquisadas. S√£o identificadas as culturas organizacionais inovativa, grupal e hier√°rquica, assim como resist√™ncias provocadas pela incerteza das mudan√ßas, incapacidade de lidar com novas tecnologias, dissocia√ß√£o de antigos grupos de trabalho e perda de poder. Os resultados obtidos apresentam sustenta√ß√£o emp√≠rica para esta proposta de investiga√ß√£o. Para trabalhos futuros foram apresentadas sugest√Ķes, como verificar a abrang√™ncia da pesquisa para empresas de economia mista e p√ļblica ou no desenvolvimento de projetos que exijam relevantes investimentos

    OBJECTIVE:To evaluate patients with transverse fractures of the shaft of the humerus treated with indirect reduction and internal fixation with plate and screws through minimally invasive technique.METHODS:Inclusion criteria were adult patients with transverse diaphyseal fractures of the humerus closed, isolated or not occurring within 15 days of the initial trauma. Exclusion criteria were patients with compound fractures.RESULTS:In two patients, proximal screw loosening occurred, however, the fractures consolidated in the same mean time as the rest of the series. Consolidation with up to 5 degrees of varus occurred in five cases and extension deficit was observed in the patient with olecranon fracture treated with tension band, which was not considered as a complication. There was no recurrence of infection or iatrogenic radial nerve injury.CONCLUSION:It can be concluded that minimally invasive osteosynthesis with bridge plate can be considered a safe and effective option for the treatment of transverse fractures of the humeral shaft.Level of Evidence III, Therapeutic Study.Universidade de Campinas Hospital das Clinicas Department of Orthopedics and TraumatologySwedish Medical CenterUniversidade Federal de S√£o Paulo (UNIFESP) Departament of Orthopedics and TraumatologyUNIFESP, Departament of Orthopedics and TraumatologySciEL

    Futebol, imprensa e memória

    This paper analyses the memory of Brazilian football on the discourse of sports press. Oblivions and silences play a part on the maintenance and construction of memories. On literate societies, newspapers play an important role on the construction of social memory. Taking this for granted, our hypothesis is that the events related to the Brazilian winners of the 1970 World Cup are narrated by the press according to a process of selection and edition that fits well to the demand of affirmation of the ‚Äúfootball-art‚ÄĚ identity. This notion brings along many images and categories that mix with Brazilian identity. We take as a corpus newspapers published during the last two World Cups (1998-2002) and the newspapers published during the 1970 World Cup, seeking to compare the images and narratives built on both historical periods, synchronic and diachronically. Keywords: football, identity, memory.O artigo analisa a mem√≥ria do futebol brasileiro nas narrativas produzidas pela imprensa esportiva. Os esquecimentos e sil√™ncios possuem uma funcionalidade na manuten√ß√£o e constru√ß√£o das mem√≥rias. Em sociedades letradas, os jornais cumprem um importante papel na constru√ß√£o da mem√≥ria social. A partir desses pressupostos, levantamos como hip√≥tese que os eventos sobre a sele√ß√£o tricampe√£ de 1970 s√£o narrados pela imprensa sofrendo um processo de sele√ß√£o e edi√ß√£o que se ajustam √†s demandas de afirma√ß√£o da identidade do futebol-arte. A id√©ia do futebol-arte traz consigo imagens e categorias que se confundem com a identidade do brasileiro. Tomamos como material de an√°lise os jornais editados durante as duas √ļltimas Copas (1998-2002) e os jornais editados durante a Copa de 1970, a fim de comparar as imagens e as narrativas constru√≠das, em sincronia com os eventos de 1970, com aquelas constru√≠das diacronicamente.

    eHabitat: A Contribution to the Model Web for Habitat Assessments and Ecological Forecasting

    Get PDF
    In striving to improve the predictive capabilities of ecological forecasting we face three basic choices ¬Ņ develop new models, improve existing ones or increase the connectivity of models so they can work together. The latter approach of chaining different interoperable models is of particular interest, as technical developments have made it increasingly viable to combine models that can answer more questions than the individual models alone, allowing users to address complex questions, often of a multi-disciplinary nature. This concept of a Model Web encourages the setting up of a dynamic network of interoperating models, communicating with each other using standardized web services. It is the purpose of this paper to introduce the potential contribution of e-Habitat to the Model Web. e-Habitat is conceived as a Web Processing Service for computing the likelihood of finding ecosystems with equal properties. By developing e-Habitat according to Model Web principles, end-users can define the thematic layers for input to the model from various sources. These input layers are discovered using standards-based catalogues, which are a fundamental component of Model Web and generic Spatial Data Infrastructures. e-Habitat integrates data ranging from remote sensing data to socio-economical indicators, thus offering a huge potential for multi-disciplinary modelling. We will show that e-Habitat can be used for the identification of habitats that are most vulnerable or of the optimal locations for monitoring stations or, when coupled with climate change model services, for ecological forecasting. As such, it is an excellent example of the Model Web in practice.JRC.H.3-Global environement monitorin

    Gastroprotective activity of the hydroethanolic extract and ethyl acetate fraction from Kalanchoe pinnata (Lam.) Pers.

    Peptic ulcers are an important pathology, and the search for safer and more effective treatment methods is of paramount importance. In this study, we assess the gastroprotective effects of the hydroethanolic extract (HE) and ethyl acetate fraction (EAF) from Kalanchoe pinnata leaves against an ethanol/HCl-induced ulcer model in rats. The HE reduced gastric lesions by approximately 47% (400 mg/kg). A significant inhibition of the gastric lesions by 50% was observed after pretreatment with the EAF (200 mg/kg). Quercetrin and quercetin 3-O-őĪ-L-arabinopyranosyl-(1‚Üí2)-őĪ-L-rhamnopyranoside were isolated and identified in the flavonoid fraction (EAF) by HPLC and NMR analyses because this fraction showed the highest gastroprotective effect. This fraction demonstrated high antioxidant activities (CE50=41.91 ¬Ķg/mL) by DPPH in comparison with Trolox(r) and 11.33 mmol Trolox(r) equivalent by ORAC. In conclusion, the HE and FAE from K. pinnata displayed gastroprotective activity in rats, most likely due to the presence of flavonoids
