A cross-sectional study was conducted to assess the association between musculoskeletal workload and psychosocial job stress variables from 100 employees from a cable making industry. It was found that the employees who had to do musculoskeletal hazardous tasks suffered higher psychosocial stress in 'decision latitude', 'job insecurity' and 'psychological job demands' also. The employees with higher level of psychosocial job stress in 'psychological job demands' and 'score of the "type A" personality' responded that they had higher 'physical job demands' from the task irrespective of its musculoskeletal hazardousness. These results confirm that musculoskeletal workload were associated with both physical and psychosocial work factors. Attention should be paid to psychosocial work factors along with physical workload to prevent musculoskeletal disorders in the manufacturing industries.

밤새 안녕히 주무셨습니까? 우리 풍속 중에서 이른 아침 동네 어르신네를 만나면 반드시 건네는 인사말이 있다. "밤새 안녕히 주무셨습니까?"가 그것이다. 이 인사말에는 중요한 의미가 내포돼 있다. 잠을 잘 잤는지에 대한 물음이 그것이다. 처음 만나 건네는 인사말에 지난 밤 잠을 잘 잤는지부터 물었던 것이다. 그만큼 잠을 잘 잔다는 것은 우리네 삶에서 중요한 의미를 가지고 있다. 우리는 인생의 1/3을 잠을 자는 데 소비한다. 어떤 사람은 그 시간이 아깝다고 아쉬워하기도 한다. 그러나 잠의 진정한 의미를 안다면 비록 인생의 1/3이란 적지 않은 시간을 잠을 자는데 소비하지만 결코 아깝지 않다는 것을 알게 될 것이다. 왜냐하면 잠을 잔다는 것은 그저 무의미한 시간의 보냄이 결코 아니다. 우리인체는 잠을 잠으로써 정상적인 생리과정을 유지할 수 있고 최상의 컨디션 또한 가질 수 있기 때문이다. 사람이 음식을 먹지 않는다면 1개월 혹은 그보다는 조금 더 오래 살 수 있지만 잠을 자지 못한다면 10일 내지 15일정도만 살 수 있는 것으로 밝혀져 있기도 하다. 이처럼 수면은 우리의 생명활동을 유지하는 데 있어서 반드시 필요한 것이며 잠을 잘자는 것은 건강징수로 가는 지금길이라고 할 수 있다.
