A research project was conducted to study work-related musculoskeletal disorders (MSDs) at a die-casting plant in Korea. The project was consisted of 4 main parts; education on the topics of MSDs for all workers, symptom survey, medical check-up, investigation of MSD risk factors. The result of symptom survey showed that 89.5% of the respondents complained pains on at least one part of the body. After cross-sectional analysis of various information and risk factors based upon NIOSH criteria, 83.3% of respondents were considered as active health surveillance level 1, and 16% of the respondents were considered as active health surveillance level 2 those are at high risk of having MSDs based upon a criteria developed by Institute of Labor Science at University of Incheon. Also the result of medical examination by a industrial medicine MD showed that 41workers(44.1%) out of 93 workers examined were considered as MSD patient group at moderate level, and 10 workers(10.8%) were considered as MSD patient group at relatively high level that require certain level of medical treatment and ergonomics interventions for their workplace. The analysis of the work environment using various ergonomic investigation techniques revealed that repeated awakard postures(50%) and highly repatitive task(37.5%) were two most contributing risk factors for the on-set of MSD at this work site followed by handling of heavy object(8.3%), and vibration(4.2%).

운전자의 안전과 감성적 요구사항이 중요시 되는 차세대 자동차의 IP(Instrument Panel) 설계를 위해 운전자으 인지특성을 고려하였다. 오디어 유닛과 HVAC(Heat, Ventilation and Air Condition)등의 주요 IP 구성요소 설계에 중점을 두었으며, 운전자의 인지특성과 가장부합하는 형태의 IP를 도출하기 위해 인지실험을 실시하였다. 첫 번째로, 기존의 차량에 설계된 IP 궁성요소를 분석하였으며, 이를 바탕으로 버튼의 수와 배열, LCD패널의 위치등을 조합하여 총 16개의 IP 프로토타입을 제작하였다. 다음으로, 제작된 프로타입을 각각 0.2, 0.4, 0.6초의 간격으로 Tachisto scope를 이용하여 피실험자에게 제시한후, 인간의 인지 지도(Human cognitive Map)에 근거한 '그리가 방법(Drawing Method)'을 이용하여 그들의 단기기억(Short-term Memory)상의 정보를 주어진 답안지에 그리도록 하였다. 이 인지실험의 다구찌 분석을 통하여 운전자의 인지특성을 고려한 최적의 IP형태를 제시하였다.
