Abstract
The object of this study is utilizing Ergonomics technique to improve workplace. The musculoskeletal disorder from the workers has been extremely common throughout the world. Percent of cases form musculoskeletal disorder has been over thirty in Europe, America and Japan. The situation is also acute in Taiwan, 33% of workers suffer from this disease reported by the Bureau of Labor Insurance. The musculoskeletal disorder not only affects labors health, but decreases productivity of companies. In order to decrease musculoskeletal disorder, excepted finding main causes of this disease by many scholars, all kinds of associations and preventive plans, including ergonomic handbooks, prevention programs and ergonomic websites were promoted in the developed countries. However, we can find that all kinds of ergonomic techniques used in improving workplace almost the same in every country. For instance, ergonomic process in workplace improvement follows the same way, including description of background, issues found, practical approaches and follow-up evaluation. We also find that practical approaches are engineering controls mostly, like rearrange workstations, use assist devices and modify work practices. Base on the good outcomes abroad, this research applied ergonomic techniques to improve freighting, goods packing, close washing and room cleaning processes in an air transportation company and its auxiliary hotel. First step is realizing the situation by site visit and then finding the clues of hazards among the process. Second step is proving the result through the OWAS and biomechanics skills. Third step is improving the process by ergonomic engineering controls. Final step is estimating effects by OWAS and biomechanics as well as step two. From the results of OWAS and biomechanics, workers working postural and physiological stress decrease and the hazards of musculoskeletal disorder are dropping off obviously.
