Are the anticipatory trunk movements occurring during load-carrying activities protective or risky?

This study evaluated anteroposterior trunk movements and the time spent on activities of load-carrying to surfaces at different heights, among experienced and inexperienced individuals. Thirty-six healthy males (16 experienced and 20 inexperienced in load-carrying) had their trunk movements recorded by an electrogoniometer while transporting boxes (7 and 15 kg) to surfaces of variable heights (low, low intermediate, high intermediate and high). Longer time was spent on trunk flexion when carrying loads to low surfaces and on trunk extension when carrying to high surfaces (p<0.05). Differences in time spent on trunk flexion/extension were identified between loads, and between groups for the heavier load. There were no differences in flexion/extension amplitudes between groups or loads. Although unnecessary flexion/extension occurring prior to a task may increase the exposure of the trunk to risky movements, the amplitudes reported here were relatively small and seemed to have occurred to facilitate the final tasks.Relevance to industryLifting devices and technological assistance are increasingly available in industrial settings. However, distribution centers and delivery services represent new demands on workers and involve an expressive amount of manual handling and carrying activities. Thus, studies on carrying strategies are necessary as they can provide guidelines for safer activities. (C) 2007 Elsevier B.V. All rights reserved.

A gestão estratégica do conhecimento sob os parâmetros dos modelos de governance corporativa nas empresas com capital aberto

This article covers the concepts about the knowledge management practices aligned with corporate governance in the organizations opened capital, highlighting the importance attached to these types of management assistance in the conduct of business organizations. Highlights the points that still have gaps existing in governance organizations models and proposes a discussion of what remains to be done by proposing the use of knowledge management models as a tool to aid the implementation of best governance practices. Through research conducted in a company with publicly traded and listed on Level 1 of corporate governance, it was possible to identify therelationship between knowledge management models aligned with corporate governance standards. A questionary that includes elements of corporate governancein line with the concepts and models of knowledge management was applied. After finding that there is strong alignment between knowledge management and corporate governance, we present the arguments about the contributions that this convergence can bring to the organization.
