This study attempted to analyze the correlation between financial ratio and operating performance of foodservice companies, using the financial data by DART service. Financial ratio is an index to identify the management of foodservice companies from calculating the ratio associating two accounts in the financial statements. Managers, creditors and investors often have different purposes for using the ratio analysis to evaluate the contents of the financial statements. According to the analysis of financial ratio and operating performance, listed food and beverage companies proved to have a high correlation in all except for interest coverage. However, foodservice companies showed a high correlation in stability and growth ratio. Therefore, managers of the foodservice companies will need to improve operating performance for using efficient utilization plans of debt from assets and operating expenses(cost of goods sold, general and other expenses).

This study was performed to find and compare the characteristics of dietary factors and obesity indices on serum lipid profiles using 407 healthy adult males that had physical examinations conducted at the general hospital located in Suwon. The subjects were divided 56.3% for the normal group, 16.7% for TG, 14.5% for TC and 12.5% for TC TG group, respectively. When comparing the blood lipid profiles to normal group, TC group was high in both total cholesterol and LDL-cholesterol, TG group was high in triglyceride and low in HDL-cholesterol, TC TG group was high in triglyceride, total cholesterol, LDL-cholesterol and low in HDL-cholesterol. In comparison of blood lipid profiles with normal group, among anthropometric factors, body weigh, BMI (Body Mass Index) and WHR (Waist Hip Ratio) showed significant differences. TC group was high in both total cholesterol and LDL-cholesterol, and TG group was high in triglyceride and low in HDL-cholesterol. TC TG group was high in triglyceride, total cholesterol and LDL-cholesterol, and was low in HDL-cholesterol. Body weigh of TG group was significantly higher than that of normal group (p<0.05). BMI and WHR of TG group and TC TG group were significantly higher than those of normal group (p<0.05). Total cholesterol was mainly related to the intake of animal lipids and alcoholic beverage. Serum triglyceride levels were closely related with lipid intake and high BMI in this group. In TC TG group, BMI and WHR were high. As well, serum LDL-cholesterol was high and HDL-cholesterol was low which indicates TC TG group had the most undesirable blood lipid profiles. Therefore, it may be necessary to manage BMI and WHR to prevent hyperlipidemia and obesity for adult males in Suwon.

The purpose of this study was performed to evaluate the prevalence of overweight and to compare the dietary behaviors, nutrient intake and physical activities of specialized game high school students. Total of 163 subjects participated and their weight, height, waist circumference, hip circumference and bone status by a quantitative ultrasound method were measured. The subjects were surveyed by a self-administered questionnaire about general characteristics, dietary behaviors and physical activities. Nutrient intakes of the subjects were assessed by semi-quantitative food frequency questionnaire. The subjects were divided into four groups on their obesity level by BMI. The prevalence of underweight, normal, overweight and obese group was 6%, 58%, 16%, and 20% respectively. BMI was negatively correlated with bone mineral density (p < 0.01) and positively correlated with WHR (p < 0.01). The dietary guideline compliance score for "Enjoy Korean rice food style" was 2.63, followed by "Prepare food sanitarily"2.48, "Do not skip breakfast"2.29, "Eat a variety of vegetables, fruits, dairy products daily"2.25, "Drink water instead of beverage"2.10, "Choose less fried foods"2.09 and "Maintain healthy weight"1.91. The exercise frequency of walking was not significantly different between groups; however, heavy exercise frequency was significantly lower in underweight group than the other groups (p < 0.05). The energy intake was 2153 kcal, which was 81.2% of the Estimate Energy Requirement, and the intake of calcium and vitamin $B_2$ was 66.7% and 77.8% of KDRIs. Particularly, the intake of iron, vitamin A and vitamin C was about 59.4%, 52.2% and 55.4% of KDRIs and INQ was 0.71, 0.63 and 0.65 respectively, and intake of folic acid fell behind 39.1% of KDRIs and INQ was 0.46. Our study suggests that the systematic and continuous nutrition education will have to be provided at schools to improve dietary and health behaviors and prevent chronic metabolic disease for students of specialized game high school.
