누적외상병 예방을 위한 Drilling 작업 빈도에 관한 연구

A laboratory experiment was conducted to examine the effect of varying working conditions on drilling frequendcy for females. Results of ANOVA showed that angle of wrist flexion and force had significant effects on drilling frequency. As angle ofwrist flexion and force increased drilling frequency decreased significantly. A set of 4 regression models were developed to predict maximum acceptable frequency (MAF) for drilling as a function of wrist flexion angle, force, and various physiological measures with could be applied in industrial situations
