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 objective of this study was to suggest a new efficiency measurement indicator for evaluating the menu management efficiency of decision making units(DMUs) in contract-foodservice operations and to determine the relationship between the DEA(data envelopment analysis) menu efficiency score and menu factors. The results of applying DEA revealed relatively efficient types of service and frequency of meals. The efficient service was shown as a self-service type that operates Monday to Saturday. The considered menu factors included meal price, food cost per meal, meal counts, number of menu items, use of favorite menu use, forecasting error, accuracy of ordering, ratio of inventory, ratio of food loss, use of processed foods and use of prepared vegetables are considered. There were significant correlations between the DEA score and meal price, meal counts, number of menu items, ratio of food loss, accuracy of ordering and use of processed foods respectively. According to the regression results, menu price had a positive influence on the DEA menu efficiency score, and food cost per meal and the use of prepared foods had negative influences respectively.

The purpose of this research was to observe the management system of 18 free meal service centers for the low-income homebound elderly in Chungcheongbuk-Do In order researchers interviewed staff members of the free meal service centers. Based on the results of interviews with staff members of the meal service organization. only two centers used a standard recipe. and most of the meal preparation was controlled under the experience of volunteers. Only two meal service centers employed dietitians due to the lak of budgets. The cost of a meal per day ranged from ￦ 556 to ￦2,750 and the number of attendants at meal service ranged from 35 to 350 persons. The budget for most of the meal service centers is not enough to provide meals for the elderly who want to participated in free meal service programs. Home delivery meal service was not considered due to the lake of manpower and areal dispersion in rural ares. Most meal service organizations did not cooperate with other community service organizations. Several improvement strategies are recommended for the effective running of the free meal service centers. First, a nutrition specialist should be included in the staff members of the service organization to provide nutritious meal service to the elderly Second, a joint control system might be introduced into the present system to reduced the cost and the recover the limitations of areal dispersion. Third, service, coordination should be considered to overcome the problem of lake resources.

The objectives of this study were to analyze the factors that affect the productivity for university food services. In a survey involving four-year university dining centers throughout the country, and correlations among thriteen different variables that affect productivity were determined. Productivity index (PI) was determined by meals per hour, the average score for 38 institutions was found to be 14.2 meals/hour. For serving methods, the fixed ration had a higher PI than the self-serving. When two types of serving trays were considered, the PI of the compartmantalized trays was higher than that of the tray accompanying saparate small dishes. When single (S)-or. multiple(M)-menu was compared with the cafeteria style, a higher PI was obtained by the S-or M-menu. Among the three operation systems, the PI was found to be the highest by direct operation (17.6 meals/hour), followed by contract operation (11.1 meals/hour) and rent operation (7.9 meals/hour). For the factors that affect the productivity of the university food services, the total number sewed (r=0.54, p＜0.001) and the use of convenient food items (r=0.28, P＜0.05) exhibited positive correlations, while food costs and labor costs showed negative correlations. This suggests that the productivity of university food service increases as the total number served and the use of convenient food item increased, but decreases as the food costs and labor costs per meal increased. A regression analysis showed that three variables - total number sewed, labor cost per meal, number of employees-influenced about 73% components of food service showed a negative correlation with PI and a positive correlation with the labor cost per meal.

This study was conducted to examine the economic evaluation of the newly developed fish meal analog (BAIFA-M) in Korean rockfish feed. A raw fish feed (MP) and two commercially formulated diets (EP) were employed to compare weight gain (WG), feed conversion ratio (FCR) and survival rate (SR) from the sea cage culture system. By using the economic model in the practical sea cage culture system, feed cost, production cost and gross profit per kg production, rate of profit to gross revenue (RPGR), and internal rate of return (IRR) were calculated based upon the results of the experiment and the information of the private aquaculture farm (Young Chang) in Tong young, Korean. IRR criteria is one of the popular economic feasibility analysis methods applicable far aquaculture industry. This is an economic evaluation method to compare the given interest rate or the discount rate with IRR which can be calculated by the difference between the present value of the benefit stream and of the cost stream. The benefits of using EP on WG, FCR, SR, and production cost will be emphasized in this study. Fish averaging 20$\pm$3.6g (Mean$\pm$SD) were randomly distributed in each small cage (6m$\times$6m) as groups of 2,000 fish. By using 3 large size cages (12m$\times$12m), 12 small cages were constructed, and only 9 small cages were employed for three replicates of each diet treatment. To compare with MP diet, two sinking EP diets were designed by our laboratory and produced by the local feed company who wanted to promote these EP diets for the mass cage culture of Korean rockfish in the future. Two EP diets contain white fish meal and/or BAIFA-M as the main animal protein sources : WFM diet, maximum 43% of white fish meal : BAIEA- M diet, 30% of white fish meal nab replaced by BAIFA- M from WFM diet. Results are summarized in Table 1. Fish fed MP diet showed significantly lower SR than does fish fed two EP diets(P<0.05). However, there Were no significant difference on FCR among fish fed three practical diets. Table 1. Average feed conversion ratio (FCR), accumulative average survival rate (SR) and economic evaluation data far three practical diets. As we expected, BAIFA-M diet is more economical than WFM diet as well as MP diet. Feed cost and production cost per kg production from BAIEA - M diet were lower than those from WFM and MP diets. Moreover, gross profit per Kg production, RPGR and IRR from BAIFA- M diet were higher than those from WFM and MP diets. This economic evaluation study clearly indicated that MP diet should be replaced by the commerical formulated EP diets as soon as possible in the near future because MP diet is not economical in the practical sea cage culture system.

The purpose of this study was to examine financial management practices in elementary school foodservices. Respondents were asked to provide information on demographics, operational characteristics, financial management activities(responsibility, importance and time demand). Data were collected from 106 elementary school foodservice using the mail questionnaire. The results were as follows 1. Time demand of 14 financial management activities was examined. The results of time-demand showed that most financial activities were performed about once per month. Reporting, inventory checking and production cost accounting were performed several times per week. 2. Major financial management activities performed by school dietitians were inventory checking, record keeping, production cost accounting, and foodservice operation planning. 3. Results of the importance rating of 14 financial management activities showed that the production cost accounting, budgeting, controlling meal costs, reporting the national treasury accounts, and inventory checking were rated as very important(4.00-4.49). Factor analysis was conducted on the importance ratings. Five activities were differentiated such as budgeting, record keeping, cost controlling, cost accounting, and reporting. The cost controlling task was identified at the most important one among them. 4. Important ratings for reporting were found to be significantly different by age, and years of experience. The younger and the less experienced were responded with higher scores on reporting. Analysis of variance for the importance scales by meal costs per one person, food cost percentage, labor cost percentage was conducted, but significant differences were not founded.

The purpose of this study were to : a) examine the current foodservice management practices by different types of elder-care sites, b)evaluate the attitudes of recipients of meal service programs, and c) provide feedback for the efficient and effective foodservice management of elder-care sites in Korea. A total of 91 elderly congregate sites was analyzed in Survey 1 and opinons of 190 recipients were surveyed in Survey 2. According to the result of meal cost analysis, the meal cost per a day was ranged from ￦728 to ￦5,500. Only 16.5% elder-care sites had one dietitian due to the lack of budges and the isolated geographical location of sites. These results suggested that financial and dystematical supports by the government would be very necessary to meet the goal of nutritional-balanced meal services at congregate sites. The survey results of recipients at sites, the mean of meal satisfaction score was rated 3.63 at the five-point scales. Significante differences were found between dependent variables(food, convenience, atmospere, menu, facility, and service) and independent variables(site type, gender, living years at sites, and health status). Thus, foodservice managers must consider characteristics of participants for menu planning, service, and distribution.

High fibre (CF, 242 g/kg) sunflower seed meal (SSM) was incorporated in standard grower and layer quail diets at 0, 50, 75 or 100 g/kg replacing part of the soybean meal (SBM) and deoiled rice bran (DORB). Each grower diet was offered to 30 quails housed in battery cages from day one to 5 weeks of age. At the end of the growing period, Twelve female quails from each of the four respective dietary groups were transferred to the individual laying cages and their laying performance from 7 to 20 weeks of age were evaluated on diets containing SSM at similar levels as that during the growing period. The results of growth bioassay revealed that the live weight gain, feed intake, nutrient retention and carcass characteristics of quails in different dietary groups did not vary significantly (p>0.05), although the quails fed SSM based diets utilized the feed less (p<0.05) efficiently than those fed the control diet. During the laying period, the egg production and egg quality traits remained unaffected due to dietary treatments but feed required per unit egg production increased (p<0.05) as the level of SSM in diet was increased to 100 g/kg. Although, the cost of feed per kg decreased due to the incorporation of SSM in diet but the same was not reflected in feed cost per unit gain, meat or egg production as such parameters were comparable on all the diets. It could thus be concluded that the SSM can be incorporated in quail diets upto 100 g/kg for part of SBM, an item usually expensive and also in short supply in developing countries including India.
