Sitting posture is common in daily life and approximate 75% of laborers usually work in sitting postures. Inappropriate sitting conditions for a long time could cause serious musculoskeletal disorders like lordosis, back pains. For this reason, studies on biomechanical and/or ergonomic features of human body are necessary for an optimal design process of chair system like chair, sofa, wheelchair, etc. In this Study, biomechanical tests to measure body pressure on seating area and muscle activities of human upper body by EMG sensors were performed to review optimal design parameters necessary for chair system development suitable for users.

급격한 경제성장 및 의료기술의 발전에 따라 세계적으로 고령화가 빠르게 진행되고 있으며 큰 사회문제로 대두되고 있다. 이러한 인구고령화에 따라 다양한 복지 용품의 시장 규모도 큰 규모로 성장하고 있으며, 수면과 휴식을 취하는 장소로서 일상의 1/3을 차지하는 침대의 중요성 또한 커지고 있다. 특히 전동침대는 등판, 다리판 각도제어, 높낮이 제어가 가능하여 사용자에게 제공되는 편의성이 높기 때문에 일상생활에서 중요성이 더욱 증가하고 있다. 하지만 등판이나 다리판의 각도조절시 사용자의 복부를 압박할 수 있으며 복부 압박이 심할 경우 호흡곤란 등의 증상을 발생시킬 수 있다. 따라서 전동침대 등판과 다리판의 구동 방식에 따른 복부 압박의 상관관계를 분석한 연구가 요구되지만 현재까지의 관련 연구는 전무한 실정이다. 본 연구에서는 삼차원 동작 분석 시스템을 사용하여 등판의 각도 조절시 절첩구조에 따른 복부 압박의 정도를 측정하였으며, 침대형 체압 측정 매트리스를 이용하여 인체와 매트리스 사이에서 발생하는 둔부 체압 변화를 측정하였다. 실험 결과에 따르면 등판의 움직임에 따라 둔부가 후퇴하는 구조의 전동침대가 단순 경첩구조의 전동침대보다 복부압박을 경감할 수 있는 구조로 판단되었다. 향후 등판 후퇴구조의 절첩 방식을 전동침대 및 Chair System 등의 등판설계에 적용할 경우 복부 압박 감소 효과가 있을 것으로 기대된다. Depending on the economic growth and development of medical technologies, the aging population is rapidly increasing. Population aging is ongoing, and thus of welfare goods market is also growing. For this reason, the bed has become an important products to spending time one third of daily life and sleep or rest. In particular, the importance of electric beds is increasing. Because of convenience and necessity by controlling the seatback angle and leg-rest angle and lift control. However, there is no research about analyze the correlation between abdominal pressure and type of adjust seatback or leg-rest angle mechanism. In this study, we analyzed the correlation between folding type of seatback angle and abdominal pressure using 3D motion analysis system. And measuring the body pressure change between subject and mattress using bed pressure mattress in hip. In the results, the bed type of hip move back depending on seatback motion was reduces the abdominal pressure than simple folding type. This results were expected to reduce the abdominal pressure by utilized the bed type of hip move back such as electric bed or chair system.

The Korean New Car Assessment Program (KNCAP) is a program to evaluate the safety of automobiles. In the safety assessment method, there are frontal collision, partial frontal collision, side collision, pillar collision, and left stability in the collision safety category. Among them, Korean in-depth analysis data shows that there are a lot of side collision accidents and it is necessary to protect them. This study will analyze the side collision accident that occurred in actual traffic accident based on Korea In-Depth Accident Study (KIDAS) and investigate the effect of center airbag on passenger in under side collision. In addition, with simulated side collision scenarios in the various side impact directions, it was investigated how the center airbag affects the driver and passenger in terms of kinematic and injury levels.

Recently, the driver can be assisted by the advanced active safety devices such as ADAS from road traffic risks. With this system, driver and passenger may freed from can driving tasks or kept eyes on forward direction while on the road. Help from adoptive cruise control, auto parking and newly develped automated driving vehicles technologies, the driver positions will vary significantly from the current standard driver position during the travel time. On this hypothesis, the objective of this study is analyze the behavior and injuries of drivers in the event of frontal impact under these abnormal driver position. Based on the KNCAP frontal impact testing method, this simulation matrix was set-up with dummies of 5 th tile female Hybrid III dummy and 50 th tile male Hybrid III dummy. The small sedan type passenger car was modeled in this simulation. The series of simulation was performed to compare the injuries and behaviour of each dummy, varying the seating status and seat position of each dummy.
