Abstract

The purpose of this study was to evaluate the height of workbench in dental lab for ergonomic body type which dental technicians are suitable and suggest to effective improvement of workspace. For this purpose, we measured the height, weight, body sizes of total 77 junior majoring in dental laboratory science where they study school located in Gyeonggi and Chungcheong area and we research uncomfortable body type when they had a clinical training. For comparative analysis we had visited 15 dental lab and 2 dental lab of general hospital and we had measured the height of workbench and desk including chair and then We had statistical analysis measured value. Especially we analyzed the important factor causing inconvenience for work environment. As a result, we had examined, we found following results The sand table was the most uncomfortable equipment, when they have clinical training. There is no correlation between sexual characteristics of junior in college and selection of uncomfortable equipment. It is reasonable to assume that sand table which is lower than recommended height brings out inconvenience. It is analyzed that the optimum height of sand table in dental lab for junior in college is lower than the recommended height. The optimum height of sand table in dental lab has deviation according to height of junior in college. The height of worktable in dental lab was lower than recommended height. The recommended range could not apply to posture of dental technician with different height uniformly.

본 연구는 치과기공사의 체형에 적합한 인간공학적인 작업 자세를 위한 작업대의 높이를 연구하고 개선방안을 제시하는 것이 목적이다. 이를 위해 경기지역과 충청도에 소재한 대학의 치기공과 3학년 학생 77명을 대상으로 학생의 신장과 몸무게 및 신체치수를 측정하였고 임상실습 시 가장 힘들었던 작업 자세에 대해 조사하였다. 또한 이를 실제작업환경과 비교 분석을 위해 수도권에 위치한 종합병원 치과기공실 2곳과 치과기공소 15곳을 직접 방문하여 의자를 포함한 책상 및 작업대 높이를 측정하여 측정값을 통계학적으로 분석 하였다. 특히 가장 많은 불편을 초래하는 원인 인자에 대해 세부적인 분석을 하였으며 이러한 분석 자료를 검토한 결과 다음과 같은 결론을 얻었다. 임상실습 시 가장 불편을 느끼는 작업대는 샌드작업대의 높이로 조사되었고 3학년 학생들의 성별과 불편한 작업대의 선택 항목간과 상관관계는 없는 것으로 분석되었다. 또한 샌드작업대가 불편했던 원인은 권장수치보다 낮은 샌드작업대의 높이 때문인 것으로 추정하였으며, 3학년 학생에게 적합한 샌드작업대의 최적의 높이는 권장치보다 다소 높은 것으로 분석되었다. 샌드작업대의 최적의 높이는 치기공과 3학년 학생의 키에 따라 다소 편차가 있었으며 개수대의 높이는 권장안보다 낮은 것으로 분석되었다. 또한 일반적으로 제시되는 권장안은 기본적으로 모든 작업자의 상이한 신장에 균일하게 적용되지 않음을 알 수 있었다.
