Abstract: the interest for the study of the stress in the labor world has been growing in the academic literature, particularly in the last years. a reason for the increase of research on this theme is the negative impact of the occupational stress in the health and in the satisfaction of employees and, consequently, in the operation and in the effectiveness of the organizations. in the economy, the negative impact of this variable has been estimated based on the supposition and on the evidence that stressed workers reduce their acting and increase the costs of the organizations with health problems, increase of absence, employee turnover and the number of accidents in the labor environment. the present work proposes to analyze the theoretical models about occupational stress and psychosocial factors. for this, we will present approaches that study the occupational stress and the psychosocial factors in the labor environment. in this article, therefore, we will present the principal models that discuss psychosocial factors and occupational stress: job-demand-control, job demand control support model, effort-reward imbalance model, ecological model and the national institute for occupational and health (niosh) proposal.

Abstract: the objective of this work was to evaluate the effects of using bulk milk with different somatic cell counts (scc) on the quality of minas frescal cheese. a randomized complete block design was used, with 3x5 factorial treatments, with three scc levels (low, 125,000 cells ml-1; intermediate, 437,000 cells ml-1; and high, 1,053,000 cells ml-1) and five storage durations. cheese was vacuum-packed in plastic bags and analyzed after 2, 9, 16, 23 and 30 days of storage at 4oc. somatic cell counts did not affect dry matter, fat, ash content, ph, free fatty acid concentrations and sensory parameters of minas frescal cheese. however, scc in milk increased losses of protein in whey and decreased the cheese protein content. these changes did not affect the moisture-adjusted cheese yield and proteolysis during 30 days of storage. an interaction effect between scc and time of storage was observed for firmness and sensory grades of cheeses. results indicated that raw milk used to produce minas frescal cheese should not contain high scc, in order to avoid lower acceptance of the product after 30 days of storage.

Abstract: objective: to determine serum cpk variation based on tsh e free t4 (ft4), and to assess serum cpk in pathological states of the thyroid (hyperthyroidism and hypothyroidism), in relation to the euthyroidism. material and methods: we evaluated retrospectively 6,230 laboratory results of tsh and cpk from 2007 to 2011. from these, 3,369 had free t4 results. we evaluated the correlation between cpk and tsh and the pathological states of the thyroid. results: the correlation between tsh and cpk was positive (r = 0.065), while that between cpk and ft4 was negative (r = -0.091, p < 0.05). from the total of results analyzed, 586 (9.4%) were measures of hyperthyroidism, with a median (range) of cpk of 98 u/l (27 to 1,113), and 556 (8.9%) were of hypothyroidism, with cpk of 114 u/l (25-4,182). conclusion: a positive correlation was found between serum cpk and tsh, and a negative correlation between cpk and ft4. cpk was lower in the group with hyperthyroidism, and greater in that with hypothyroidism.
Beyond Technology, there Stands Magic
Lúcia Fernandes Lobato
Revista Brasileira de Estudos da Presen?a , 2013,
Abstract: This article shows evidence that despite the prominent influences of the technological revolution and the spectacular panoramas on the contemporary world, magic seems to stand beyond technology. To support this hypothesis, the author investigates the images on the cinema, pointing out that to discover magic in a film, for instance, it is necessary to recognize its subjective structures disguised in the objectivity of the screen. Finally, the author indicates that in the field of image production, dance films that are created out of a cross-disciplinary effort are another by product of the fusion between art and video, born out of technological advancements.
