The purposes of this study were to: a) examine characteristics of foodservice management practices; b) investigate characteristics of recipients; c) analyze foodservice systems; and d) provide feedback for the efficient and effective foodservice management of mental disorder care sites in Korea. A total of 46 sites was analyzed by questionnaire survey. Statistical data analysis was completed using the SPSS package program for descriptive analysis. As results of site recipients' characteristics, 60% of total sites were males and 40% were female recipients. Average 60% of recipients were from 30 to 40 years old. Major diseases of recipients were mental disorder, high pressure, and obesity. According to the result of foodservice system analysis, the average meal cost per day was about 2,921 won and average food cost percentage was 39%. Average number of meals per day was about 600 meals. All sites had on dietitian and 88.3% of sites had one cook as a full-time employees. In the part of procurement, dietitians were major chargers of sites for purchasing foods. Major purchasing method was the order and delivery contract. About a half of sites used cycle menu system and standardized recipies. Most of sites had recipients survey systems for evaluating meal satisfaction. About 60% of sites provided liquid diets to recepients and 22% provided diabetic diets. Dietitians at sites had problems on low meal cost budget, lack of cooking professionals, and lack of information about treatment meals for mental disorders for providing higher quality of foods cure recipients. The results suggested that financial and systematical supports by the government would be very necessary to meet the goal of nutritional balanced meal services.

The purpose of this study is to find out its effect on changes in the joint angle and the success rate of cardiopulmonary resuscitation by conducting cardiopulmonary resuscitation (CPR) when wearing and not wearing PPE (personal protective equipment) targeting 20 paramedics with more than 5 years of experience. The subjects carried out CPR in 30:2 for 4 minutes and collected images were digitized by Kwon3D XP Software Package(Version 4.0) and then data were obtained. Data, which were collected by analyzing the motion when starting in one cycle, when pressing to the maximum, in the final position (relaxed), were analyzed by using SPSS 18.0. In conclusion, during CPR, the angle of the both shoulder joints was not significant (p>.05) and the angle of the right elbow joint was reduced in all positions and was statistically significant (p<.05) and the angle of the left was significantly reduced in the maximum pressure posture and the final position (p>.05). In the case of the trunk, the angle increased statistically significantly at all stages (p<.01, p<.001). Also, during CPR, the average compression rate was significantly reduced after wearing PPE (p<.05) and average hand escape time by cycle increased statistically significantly (p<.05) but chest compression execution rate at the correct depth did not show any significant difference between the two groups (p>05).

The relationship between bone mineral density and the environmental factors were investigated from the view point of preventing osteoporosis in Korean pubescent girls. The effects of calcium, nutrient intake, physical activity on total bone mineral density, lumbar spine and femoral bone mineral density and total bone mineral content were evaluated 33 healthy pubescent girls aged 14∼16y. A convenient method was used to assess nutritional and energy intake and calcium index was used together. Calcium intake in childhood was estimated by asking whether subjects usually drank milk as children. Eating habits data and history of menstruation were obtained by questionnaire and interview. Average energy expenditure was calculated. Bone mineral density and content were measured by dual energy x-ray absorptiometry using a Lunar DPX＋Scanner (Lunar, Madison, WI). The lumbar spine(L2∼L4) and three sites in the proximal femur (femoral neck, trochanteric region, and Ward's triangle)were measured. Height and weight were measured, and the body mass index(BMI) was derived from the formula : BMI=kg/㎡ Statistical analysis was performed by simple correlation using the SAS package. The mean calcium intake (736mg) was below the RDA of 800mg/d. Twelve percent of the total subjects did not drink milk at all because they did not like the taste. Skipping meals, low calcium intake and low energy intake were significantly correlated with the low BMD. Also the data indicate that girls who reported drinking milk with every meal during childhood had significantly higher bone densities than girls who reported drinking milk less frequently. The results suggest that milk consumption in childhood appears to be needed not only for growth and development, but possibly also to assure an optimal peak of bone mass and thus greater latitude for the maintenance or skeletal integrity in the face of bone losses. There was a highly significant correlation between the total BMD and overall level of physical activity. Body weight was a better predictor of total BMD than was and other factor. Simple mechanical loading may explain why body weight, but total BMC was positively relatd to height. Conclusively, increasing calcium intake and physical activity in the pubescent girls could influence BMD.

Large scale fire tests were conducted to develop water mist nozzles as a component of fixed water- based fire fighting systems for Ro-Ro spaces and special category spaces. Fire scenarios for this system consist of two cases which are for cargo fire in a simulated truck and for passenger vehicle fire, and each case has 3 different tests according to the position between fixed water mist nozzles and fire source. Every experiment proceeded for 30 minutes and acceptance criteria were based on gas temperature, fuel package's damage and ignition of targets. This study primarily dealt with the experimental results of cargo fire and focused on fire suppression capability in accordance with discharge pressure, flow rate and flow characteristics like swirl and penetration of the developed water mist nozzles. It appeared that low pressure water mist nozzles with about 40 L/min were able to control fire occurred in Ro-Ro spaces.
