Improving ergonomics to prevent musculoskeletal disorders (MSDs) is a key element of OSH programs for most organizations. MSDs are a major cause of losses and a persistent source of frustration. The authors have heard from OSH managers about the challenges in proving to their top managers the effectiveness and value of their current ergonomics program. Through benchmarking studies and experienc...

This paper addresses the design of an assembly system facility consisting of multiple assembly lines of different shapes. In such a design problem there are two conflicting objectives: (i) to minimize the overall area of the facility; and (ii) to maximize the efficiency of the material handling transportation system. We first address the optimization problem of objective (ii) when replacing obj...

BACKGROUND Our aim was to assess the safety and efficiency of operating microscope use by surgeons in thyroid surgery to reduce static neck flexion. METHODS A retrospective case review comparing thyroidectomies performed using an operating microscope to those using surgical loupes was done. Operative times and incidence of complications were compared between total thyroidectomy procedures don...
