    Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Engenharia de Produção."Competência Comunicativa" no ambiente de trabalho não se trata simplesmente de transmitir uma informação e ela chegar ao seu destino. "Competência Comunicativa" refere-se à capacidade do indivíduo de saber recrutar e mobilizar competências e habilidades da comunicação e colocá-las em prática nas suas relações interpessoais. Objetivando saber quais são estas competências e habilidades que compõem as "Competências Comunicativas", procurou-se desenvolver e aplicar a Ferramenta de Identificação de Competências Comunicativas em Ambientes de Trabalho, o FICCAT. Este instrumento foi aplicado em diversos setores de uma indústria têxtil, entre encarregados e demais trabalhadores dos setores de planejamento e produção. A ferramenta leva em consideração o perfil da empresa, o levantamento populacional e inter-relacional, a relevância e a freqüência de exigência pelo ambiente de trabalho das competências comunicativas, além de uma meta avaliação da própria ferramenta. A aplicação do instrumento gerou uma listagem de competências e habilidades relevantes, em ambientes de trabalho real e ainda, possibilita uma gama de novos estudos com base neste material

    Orientador: Juarez Cirino dos SantosMonografia (graduação) - Universidade Federal do Paraná, Setor de Ciências Jurídicas, Curso de Graduação em DireitoAnálise do comportamento anti-social do adolescente brasileiro à luz de sua peculiar condição de pessoa em desenvolvimento e da realidade fática em que grande maioria deles vive. Apesar de o legislador pátrio assegurar-lhe proteção prioritária, por meio da adoção da Doutrina da Proteção Integral, a efetivação desta nova forma de ver, entender e atender o adolescente, principalmente aquele que apresenta comportamentos anti-sociais, deve vir acompanhada tanto por uma mudança de pensamento da sociedade, quanto por um agir positivo por parte do Estado. Levar-se-á em conta o fato de tais jovens, por estarem passando pela adolescência, enfrentam alterações físicas, psicológicas e hormonais. Agravando tais fatores, existe a total omissão do Estado em face da classe social a que pertencem, contribuindo para a perpetuação das mais adversas condições em que grande parcela deles vive. Sendo entendido dentro deste contexto, o adolescente brasileiro deve receber um tratamento adequado em decorrência de suas reais necessidades, evitando-se a banalização de medidas sócio-educativas segregatórias e, por consequência, oferecendo-lhes oportunidades e condições de prosperar. Para tanto sociedade e Estado devem agir em conjunto em prol da juventude nacional, aplicando-se as medidas que já estão à nossa disposição legalmente

    Background: The measurement of biomarkers in cerebrospinal fluid (CSF) has gained increasing acceptance in establishing the diagnosis of some neurodegenerative diseases. Heart-type fatty acid-binding protein (H-FABP) was recently discovered in CSF and serum of patients with neurodegenerative diseases. Objective: We investigated H-FABP in CSF and serum alone and in combination with CSF tau protein to evaluate these as potential biomarkers for the differentiation between dementia with Lewy bodies (DLB) and Alzheimer's disease (AD). Methods: We established H-FABP and tau protein values in a set of 144 persons with DLB (n = 33), Parkinson disease with dementia (PDD; n = 25), AD (n = 35) and nonclemented neurological controls (NNC; n = 51). Additionally, serum H-FABP levels were analyzed in idiopathic Parkinson disease patients without evidence of cognitive decline (n = 45) using commercially available enzyme-linked immunosorbent assays. We calculated absolute values of HFABP and tau protein in CSF and serum and established relative ratios between the two to obtain the best possible match for the clinical working diagnosis. Results: Serum HFABP levels were elevated in DLB and PDD patients compared with NNC and AD subjects. To better discriminate between DLB and AD, we calculated the ratio of serum H-FABP to CSF tau protein levels. At the arbitrary chosen cutoff ratio >= 8 this quotient reached a sensitivity of 91% and a specificity of 66%. Conclusion: Our results suggest that the measurement of CSF tau protein, together with H-FABP quantification in serum and CSF, and the ratio of serum H-FABP to CSF tau protein represent marker candidates for the differentiation between AD and DLB.

    Loss of Glucocorticoid Receptor Expression by DNA Methylation Prevents Glucocorticoid Induced Apoptosis in Human Small Cell Lung Cancer Cells

    Human small cell lung cancer (SCLC) is highly aggressive, and quickly develops resistance to therapy. SCLC cells are typically insensitive to glucocorticoids due to impaired glucocorticoid receptor (GR) expression. This is important as we have previously shown that expression of a GR transgene induces cell death in-vitro, and inhibits tumor growth in-vivo. However, the underlying mechanism for loss of GR expression is unknown. The SCLC cell line, DMS79, has low GR expression, compared to non-SCLC cell lines and normal bronchial epithelial cells. Retroviral GR expression in DMS79 cells caused activation of the apoptotic pathway as evidenced by marked induction of caspase-3 activity. Methylation analysis of the GR promoter revealed some methylation in the 1D, and 1E promoters of the GR gene, however the ubiquitous constitutively active 1C promoter was heavily methylated. In the 1C promoter there was a highly significant increase in DNA methylation in a panel of 14 human SCLC cell lines compared to a mixed panel of GR expressing, and non-expressing cell lines, and to peripheral blood mononuclear cells. Furthermore, within the panel of SCLC cell lines there was a significant negative correlation seen between methylation of the 1C promoter, and GR protein expression. Reversal of GR gene methylation with DNA methyltransferase inhibition caused increased GR mRNA and protein expression in SCLC but not non-SCLC cells. This resulted in increased Gc sensitivity, decreased Bcl-2 expression and increased caspase-3 activity in SCLC cells. These data suggest that DNA methylation decreases GR gene expression in human SCLC cells, in a similar manner to that for conventional tumor suppressor genes

    Increased DJ-1 expression under oxidative stress and in Alzheimer's disease brains

    Mutations in the DJ-1 gene have been linked to autosomal recessive familial Parkinson's disease. To understand the function of DJ-1, we determined the DJ-1 expression in both zebrafish and post mortem human brains. We found that DJ-1 was expressed early during zebrafish development and throughout adulthood. Knock down (KD) of DJ-1 by injection of morpholino did not cause dramatic morphologic alterations during development, and no loss of dopaminergic neurons was observed in embryos lacking DJ-1. However, DJ-1 KD embryos were more susceptible to programmed cell death. While a slight reduction in staining for islet-1 positive neurons was observed in both DJ-1 KD and H2O2 treated embryos, the number of apoptotic cells was significantly increased in both KD and H2O2 treated embryos. Interestingly, DJ-1 expression was increased in brains of zebrafish under conditions of oxidative stress, indicating that DJ-1 is a part of stress-responsive machinery. Since oxidative stress is one of the major contributors to the development of Alzheimer's disease (AD), we also examined DJ-1 expression in AD brains. Using DJ-1 specific antibodies, we failed to detect a robust staining of DJ-1 in brain tissues from control subjects. However, DJ-1 immunoreactivity was detected in hippocampal pyramidal neurons and astrocytes of AD brains. Therefore, our results strongly suggest that DJ-1 expression is not necessary during zebrafish development but can be induced in zebrafish exposed to oxidative stress and is present in human AD brains

    Effects of awareness and task relevance on neurocomputational models of mismatch negativity generation

    Detection of regularities and their violations in sensory input is key to perception. Violations are indexed by an early EEG component called the mismatch negativity (MMN) – even if participants are distracted or unaware of the stimuli. On a mechanistic level, two dominant models have been suggested to contribute to the MMN: adaptation and prediction. Whether and how context conditions, such as awareness and task relevance, modulate the mechanisms of MMN generation is unknown. We conducted an EEG study disentangling influences of task relevance and awareness on the visual MMN. Then, we estimated different computational models for the generation of single-trial amplitudes in the MMN time window. Amplitudes were best explained by a prediction error model when stimuli were task-relevant but by an adaptation model when task-irrelevant and unaware. Thus, mismatch generation does not rely on one predominant mechanism but mechanisms vary with task relevance of s
