現場製造人員比現場品管人員身體出現疼痛的盛行率較高，尤其是頸部、肩膀、上背、手掌、下背或腰部不適人數比例為高，分別為54﹪、52﹪、52﹪、58﹪、66﹪；現場製造人員主訴疼痛部位與部份工作內容有相關性，其中如頸部與舉手過肩總時間(2hrs)、上背與扭腰轉身總次數(11次~20次) 、手腕與手指用力捏握（夾）總時間(2hrs) 、下背或腰部與搬抬物品總重量(10公斤~50公斤) 、下背或腰部與扭腰轉身總次數(11次~20次)；現場製造人員主訴疼痛部位與部份身體動作有相關性，如頸部與洗淨、上背與原料投入處理、手腕與充填、下背或腰部與原料前處理 ，以上在統計上都有顯著相關（P<0.05）。
Optoelectronics industry in Taiwan is an important high-tech industry. However, there are increasing musculoskeletal discomfort reports of clean-room workers engaged in the optoelectronics industry. This study aimed to investigate labor work hazards led by photoresist of optoelectronic industry.
The subjects of this cross sectional study who are 50 on-site manufacturing and 20 quality control staffs working in clean rooms of a photoresist manufacturing company are conducted to assess the working conditions and skin problems by the self-designed structural questionnaire. Nordic Musculoskeletal Questionnaire (NMQ) was adopted to investigate the musculoskeletal symptoms and relevant skin problems and MSDs was utilized to analyze the risk factor in field work. Chi-square test was used analyze the relationship between risk factors exposure and symptoms.
On-site manufacturing workers have the higher prevalence of body pain symptom than quality control personnel, especially the high proportion in neck, shoulders, upper back, hands, lower back or waist with 54%, 52%, 52% 58%, 66% accordingly. The major body part pain complained by the on-site manufacturing staffs has certain relationship with the work contents, including the neck and the raising total time (2hrs) of hands over the shoulders, the upper back and the twister total number (11 ~ 20 times) of waist, the wrist and forceful pinch total time (2hrs) of finger, lower back or waist and total weight of goods carried (10 kg ~ 50 kg), lower back or waist and the twister total number (11~ 20 times) of waist. The major body part pain complained by the on-site manufacturing staffs has certain relationship with the body movements, such as neck and clean-up, upper back and raw materials injecting process, wrist and filling, as well as lower back or waist and raw materials pre-processing. The above-mentioned are significantly correlated (P <0.05) in statistics.
The on-site manufacturing staffs also have higher prevalence of skin discomfort than quality control personnel, especially the highest hand back ratio (52%) with statistically significant correlation (P <0.05). There are 16 staffs (32%) were diagnosed with contact dermatitis in the 50 manufacturing personnel subjects. In which, there were 15 patients (30% of the total on-site manufacturing staffs) belonged to stimulus contact dermatitis and occurred mainly in hands.
Photoresist manufacturing workers have a high proportion of musculoskeletal discomfort and skin problems that have to be prevented by personal protection and ergonomic designs in the future.
