Chest lateral decubitus is a chest examination to determine the persence of pleural fluid in thorax. In this study, we prepare recumbent holding position time standard of chest lateral decubitus. The records of 15 patients with chest lateral decubitus between May and Jun. Recumbent holding time is 30, 60, 90, 120, 180, 210, 240 seconds. The result is fluid level change between 0.88mm to 9.63. Fluid heigh change between 9.9 percent to 42.5 percent. We can confirm fluid level change with chest decubitus image. The proper time for fluid level change is 180 seconds.

The purpose of this study was to assess visual biofeedback's influence on trunk muscles' (EMG) activity and endurance holding time for correct position during whole-body tilt exercise. For the study, we recruited 14 volunteers who showed no symptom of lumbar disease during medical tests. We measured the EMG activity of their rectus abdominis, external abdominal oblique, internal abdominal oblique and erector spinae muscles, and their endurance holding time for correct position during anterior and posterior whole-body tilt under two conditions: whole-body tilt with and without visual biofeedback. Resistance with gravitational force on the trunk during whole-body tilt was applied by using a device that had a monitor on which the subjects could check their alignment and that sounded an alarm if a subject's alignment collapsed. The study showed an increase in the EMG activity of external abdominal oblique, internal abdominal oblique/rectus abdominis ratio and endurance holding time for correct position during both anterior and posterior whole-body tilt with visual biofeedback compared with without visual biofeedback (p<.05). We suggest that the whole-body tilt exercise with visual biofeedback could be a beneficial strategy for selectively strengthening the internal abdominal oblique muscle and minimizing the rectus abdominis muscle's activity while maintaining correct alignment during whole-body tilt exercise.

The objective of this study is to provide a fundamental data to improve meals of the college foodservice operations serving more than 300 meals per day through evaluating changes in; total vitamin C contests, water contents, and pH, in the process of handling such foods as soybean sprout cooked and of fresh vegetable salads. This study, also, tried to identify nutrition reduction, step by step, to minimize nutrition loss. 1. In handing COOKED SOYBEAN SPROUTS, total vitamin C contents were higher after wash(1.54%mg%) than other cooking methods adopted in university meals(1.08mg%), however, total vitamin C contents was significantly lost during boiling step. 2. Significant loss of total vitamin C and water content in the FRESH VEGITABLE SALADS was detected in the process of washing and cutting vegitables. Especially,'cabbage' lost 20% of total vitamin C in the process of 'soaking in water', which was one of preparation process 3. Significant loss of vitamin C was observed after 6 hours of HOLDINC AFTER COOKING but it can be reduced through holding under lower temparature, in case of soybean sprouts and fresh vegitable salads. pH became acidic as holding time expanded. WATER CONTENT of cooked soybean sprouts decreased up to 4 hours holding time, however, it increased when we checked at after 6 hours' of holding time. Water content continuously decreased up to 6 hours of holding time in case of FRESH VESITABLE SALADS with the statistically significance level.

원료 양송이의 수확시기 및 보관 기간에 따른 신선편이 가공적성을 비교키 위하여 계절별로 수확한 양송이를 각각2 에 보관하면서 주기적으로 일정량씩을 취하여 각각 절단한 후 5 에 방치하면서 표면의 갈변진행정도와 총 페놀화합물 함량 변화를 조사하였다. 원료 양송이의 호흡률은 여름철 및 가을철에 수확한 것이 9.5510.47 mLCOkghr로 봄철 및 겨울철에 수확한 것에 비해 낮았고, 중량감소율은 봄에 수확한 양송이가 가장 낮았다. 원료상태로 보관한
