작업대높이에 따른 피로도와 일의 능률상의 변화 = Changes in Fatigue and Performance Error as a Function of Standing-Workable Height

다국어 초록 (Multilingual Abstract)

The purpose of this study was to determine whether the best standing worktable height considered as optimal size on the basis of theoretically optimal height or empirically optimal height. The theoretically optimal standing-worktable predicated on the means of Japanese adults' anthropometic measures turned out to be about 90cm. The empirically optimal worktable height of 95cm was determined on the basis of worker's subjective report. And two groups of 20 subjects were paired assigned to two worktable's conditions with different height(90,95cm).
Before having them work and after work, subjects' mental fatigue levels were measured by Flicker-Tester. The performance task of subjects were carburet-assembling. The results of this study are as follows : First, the fatigue level(CFF) in the theoretical condion was significantly higher than the empirical condition. Second, the performance error percent in the theoretical condition was significantly higher than the empirical condition.
