성토 하에 매설된 강성관에 있어서 관의 두께, 매설상태, 성토높이, 성토흙의 탄성계수, 트렌치의 폭 및 깊이 등이 매설관에 작용하는 응력에 미치는 영향에 대해서 유한요소법의 선형해석을 이용하여 검토하였다. 관 주위의 수직접촉헌력의 분포와 수직하중을 선형중도귀식으로 나타내었으며, Marston-Spangler 이론에 의해서 구한 수직하중은 유한요소해석에 의한 값보다 일반적으로 크다. 그리고 Marston Spangler이론에서 이용되는 침하비는 항상 일정하지 않고 위에서 언급한 여러가지 요인의 유기에 따라서 달라진다는 사실을 알았다. The behaviour of buried rigid pipe under embankment is analysed by a linear finite element program to study the influence of variation of the geometry of soil-conduit pipe system and elastic modulus of soil on the pipe response. The geometry of the system considered includes the thickness of pipe, the height of embankment, and the width arid the depth of trench. The normal contact pressure distribution around the pipe and the vertical load on the pipe are modelled by a multiple linear regression. And the vertical load on the pipe computed by Marston-Spangles Theory Is generally larger than that by finite element analysis. The settiement ratio in Marston-Spangler Theory is found to be variable for various for various of all factors mentioned above.

The purposes of this study are to analyze the problems of the elderly using kitchens by ergonomic work evaluation methods, and to make suggestions for planning and remodeling of the kitchens for the elderly. The work evaluation methods which used in this study were direct-observing methods, which contained the process of 2 or 3 times each visiting to four different houses where elderly people live. For direct-observing methods, analyzing with movement observations and observation methods with photos and videos were used. Characteristics of subject elderly people and problems of their kitchens were analyzed by static measurements, interviews, pictures, and videos. The data, which are recorded movements of the preparing meal of the elderly were analyzed by playing it back repeatedly. As results, physical characteristics of the elderly was the most important consideration; a participant with the arthritical knee was limping at the kitchen entrance due to the difference of the floor level, and a user with a bent back was working on the floor or place an elbow on the worktable to support her body. Those results made a conclusion about the common problems of the kitchens, and suggested the check list which has to be considered when designing the elderly using kitchen.
