Object: The aim of this study is to develop new K-OWAS on the basis of the anthropometry of Koreans considering works in shipbuilding and heavy industry for evaluation whole-body working postures. Background: Work Related Musculoskeletal Disorders(WMSDs) were a leading cause of sick leaves and injuries in the industries of our country. Especially, awkward working postures and handling of heavy weight are known as a main cause of WMSDs.

피실험자는 과거 병력 상 전신, 어깨, 허리, 무릎, 발목의 관절 운동범위에 제한이 없으며, 피로, 통증, 지각이상 등의 근골격계장애가 없는 5명의 20대 남자 대학생을 대상으로 하였다. 성별에 따른 차이를 없애기 위하여 전원 남성으로 선정하였다. 피실험자의 평균 나이는 24.8세, 평균 신장은 172cm, 평균 몸무게는 67.4kg이었다.
3.2. Evaluation of Subjective Discomfort and Body Parts
주관적 불편도 평가는 Borg’s CR-10 Scale을 사용하였다(Borg, 1993).

본 연구는 전신작업 평가 시 주로 사용되는 OWAS의 단점을 보완하고, 한국인의 작업 현황에 맞게 변형된 OWAS를 개발하기 위하여 새로운 전신작업 평가 기법인 K-OWAS를 제안하였다.
본 연구의 결과로서 OWAS를 이용한 5종류의 작업 자세에 대한 조치단계와 전신, 허리, 무릎, 발목의 주관적 불편도의 상관관계는 모두 낮다고 나타났다. 그리고 OWAS의 조치단계와 전신, 허리, 무릎, 발목의 주관적 불편도의 상관관계는 통계적으로 유의하지 않은 것으로 나타났다(p>0.05). 따라서 OWAS 는 작업자의 주관적 불편도를 반영하지 못하고 있다.
