The aims of this study was to suggest a new efficiency measurement indicator for evaluating the management efficiency of decision making units(DMUs) in the contract foodservice industry. The data envelopment analysis(DEA) model which considers multiple inputs and outputs and looking for benchmarks, was used to compare the productivity of DMUs. We considered sales, profits, and customer satisfaction as output variables and it adopted food cost, labor cost and administrative expense as input variables. The results of applying DEA revealed relatively efficient types of business and service types. The efficiency of school units was highest and the mired service type was the most efficient one. In this study the CCR model efficiency was analysed with profit and the customer satisfaction index by the matrix method. DEA efficiency was correlated with profit but there was no correlation between DEA efficiency and the customer satisfaction index.

The purpose of this study was to provide dietitians with the guidance in forecasting meal counts for a university/college foodservice facility. The forecasting methods to be analyzed were the following: naive model 1, 2, and 3; moving average, double moving average, simple exponential smoothing, double exponential smoothing, Holt's, and Winters' methods, and simple linear regression. The accuracy of the forecasting methods was measured using mean squared error and Theil's U-statistic. This study showed how to project meal counts using 10 forecasting methods for dietitians. The results of this study showed that WES was the most accurate forecasting method, followed by $na\ddot{i}ve$ 2 and naive 3 models. However, naive model 2 and 3 were recommended for using by dietitians in university/college dining facilities because of the accuracy and ease of use. In addition, the 2000 spring semester data were better than the 2000 fall semester data to forecast 2001spring semester data.

The purpose of this study was to compare the usage of beef and foodservice managers' perceptions of beef quality by foodservice type. A survey was conducted on 546 dietitians, and 499 acceptable responses were used for data analysis. By weight, pork was the most used meat in foodservice institutions, followed by poultry and beef. More than half of the foodservices selected meat suppliers by competitive bidding. Approximately 85.8% of the respondents used Hanwoo beef, followed by Australian beef and Youku beef. Beef type differed significantly by foodservice type (P<0.001): most of the schools and social welfare facilities used Hanwoo beef, whereas most hospitals and business/industry operations used Australian beef. When purchasing beef, safety of beef was rated the most important, while eco-friendliness was rated the least important. Most of the dietitians understood that marbling is one of the determinants of the beef quality, but were not aware of other components. Dietitians that selected Hanwoo and Youku beef were more satisfied with quality, taste, nutrition, freshness, country of origin, package, customer, preference, and availability for various menus than those who used imported beef. Dietitians who used Hanwoo beef were the most satisfied with country of origin, whereas the others were the most satisfied with safety. Since the dietitians are in charge of planning menus and selecting meat suppliers at foodservice institutions, they should make knowledgeable decisions by understanding meat supply systems and quality of beef.

This study is to seek methods for optimum management of foodservice system for elementary schools in Korea through surveying and analyzing the current status of the "common-management foodservice system" and certain important factors relating to its operations. For the survey of the current status of the "common-management foodservice system", questionnaires are prepared as against schools adopting "common-management system"("Common Schools") as well as schools adopting "conventional management system" ("Conventional Schools") in Kyungsangbookdo ("Kyungbook") area. The survey items are composed of general items, items concerning tasks of dietitians, items concerning purchasing activities and items concerning level of recognition and job-satisfaction of the dietitians. Total 46 dietitians from Common Schools and 65 dietitians from Conventional Schools in Kyungbook region responded the questionnaires. The results of this study are as follows: 1. Information Concerning Dietitians Average age of the dietitians: 26.6 yrs Ratio of two years or less of experiences as school dietitian: Dietitians from Common Schools: 59.1％ Dietitians from Conventional Schools: 50.8％ 2. Types of the Foodservice In both schools, rural type are prevalent; however, between urban types and islands types, the ratio of urban types are larger than the ratio of islands types in Conventional Schools, and the opposite is true in Common Schools. 3. Decision of Suppliers The ratio of dietitian＇s participaion in the decision making reaches only 38.3％, indicating the possibility of problems in quality control and hygienic aspects of the food supply. 4. Factor Analysis of the Foodservice Duties Food supply and general affairs administration work was carried out very well (4.2), while personnel management and operational improvement work (2.8), nutritional education work (2.3), and information related work were poorly carried out. No significant differences were found between the two types of the foodservice management systems. 5. Job Satisfaction scores of Dietitians Dietitians were more satisfied with the works (50.0), supervision (50.5) and co-workers (46.9) than pay (18.0) and promotion (22.3).

This study has attempted to collect actual spot's opinions and analyze importance-performance of indicators for the evaluation of hospital nutrition department. The results of this research were as follows: first, the average score of self-estimated performance was 3.75 based on a 5-point scale. The degrees of importance of hospital foodservice and nutrition department management were in the range of 3.71~4.85 out of 5.0 and the mean importance degree score was 4.37. Second, the average score of self-estimated performance in each category was significantly higher in the case of general special hospital compared to general hospital. Especially average performance score of nutrition management in the general special hospital was higher than that of general hospital (P<0.001). The average performance score of the hospital with more beds was significantly higher than that with less beds. Contract managed hospital's score was significantly higher than that of self-operated hospital in two categories, "facilities management" and "nutrition management" (P<0.05, P<0.01). In foodservice and nutrition management of task-separated hospitals, the average performance scores were significantly higher than those of not-separated hospitals (P<0.01, P<0.001). Third, according to the importance-performance analysis of recognition about indicators for the hospital nutrition department's operations evaluation, 'foodservice facilities management' and 'foodservice sanitation management' were in 'doing great', 'nutritional management' and 'operational management' were in 'low priority', and 'other foodservice management' was in 'overdone'. In conclusion, there's a need for institutional specific standards of sanitation for Korean hospital foodservice.

This study was designed to identify how customers considered menu selection attributes on menu choice, and so the instrument for measuring that question was developed and menu selection behavior types were analyzed by customers' characteristics. Cronbach's alpha to assess the internal reliability of the developed scales was 0.8361, which indicated to be highly reliable. Construct validity was assessed by principal components factor analysis with a Varimax rotation to identify underlying dimensions of menu selection and then four factors explaining 55.618% of the total variance were found. These factors were labeled as 'quality of meals', 'attractiveness of meals', 'healthfulness of meals' and 'variety of meals', respectively. As a result of analysis on menu selection factors, 'quality of meals'(3.82 out of 5) was the highest consideration followed by 'variety of meals'(3.51), 'healthfulness of meals'(3.49) and 'attractiveness of meals'(3.34), so that menu marketing approaches in the perspective of quality of meals would do lead customers' selection rates, customer satisfaction and then sales highly. Frequent visitor selected menu indifferently but customers who were interested in food and menu highly, who perceived meals' quality highly, and who were satisfied with overall foodservice did with concern. On the basis of these results of study for the target of food court-style B ＆ I foodservice operation, which was introduced as an ideal model in future foodservice market by the concept of 'customer's selection right', the following study related with customers' meal patterns and perception of foodservice by menu selection attributes would be able to predict the chances for success of food court-style foodservice operations.

Concerns regarding work and food safety in foodservice operations are growing. The purpose of the study is to suggest guidelines for designing foodservice facilities, including school foodservices and Korean restaurants. A case of a franchise restaurant specializing in a Korean food item, Seolleongtang, was used to explain the facility design. The contents of the manual included ways to determine space allocation, calculate the application of utilities and the diameters of supply utility pipelines, and suggestions on how to decide on air conditioning equipment. The standards of the American Gas Association and the Japan Foodservice Equipment Association (JFEA) were applied to design the restaurant space. The JFEA standards and knowledge based on experience and statistics were applied to calculate the usage of utilities like fuel and water. The standards of JFEA and the Society of Heating, Air-Conditioning, and Sanitary Engineers of Japan were applied to calculate the diameters of the water supply and drainage pipelines. For the setting of the heating, ventilation, and air conditioning systems, three ways to carry out the calculation of effective ventilation were explained, as well as options to dicide the standard parameters of the duct and ventilation fans. This manual can contribute to the design of effective and efficient foodservice facilities and help secure the work safety of foodservice employees thereby ensuring food safety.

본 연구에서는 음식점의 남은 음식물의 정의를 설정하고, 남은 음식물 저감화와 남은 음식물 재사용 근절을 위한 방안과 이러한 문제가 제대로 지켜지지 않는 원인에 대하여 관련 분야의 전문가 34인과 영업주 14인을 대상으로 면접조사 및 설문조사를 통해 남은 음식물 관리에 관한 정책적개선 방안을 제안하였다. 전문가들은 수저가 닿지 않았던 음식이라도 제공된 후 남은 음식은 재사용할 수 없다는 데 동의하였다. 즉, 수저가 닿은 김치를 포함한 모든 반찬류와 피클은 한번 제공된 후 버려야 한다. 단, 쌈채소, 고추 등의 야채류는 세척 소독 후 재사용 혹은 가열음식에 재사용하는 경우 허용된다고 응답하였다. 급식관리 전문가와 식품위생 전문가가 제공된 후 손대지 않은 채 남은 김치를 다시 재활용하거나 가열식품의 조리에 이용할 수 없다고 주로 응답한데 반해, 식품접객업 영업자들은 재활용 할 수 있다고 응답하여, 실제 음식점 영업 현장에서 김치류의 재활용 가능성이 높은 것으로 추정된다. 남은 음식 저감화가 이루어 지지 않는 원인과 남은 음식 재사용의 원인으로는 '한국적 식문화'와 '대국민 홍보부족'이 공통적인 원인으로 지적되었다. 또한 전문가들은 이 두 문제를 해결하기 위한 방안으로 '대국민 홍보'와 '소비자 및 영업 주 종사원 교육'을 통한 식생활 개선과 현장 음식문화 개선을 공통적으로 제안하였다. 과거에 음식문화 개선이 영업자 중심으로 이루어졌기 때문에 실제 소비자들의 관심과 협조를 유발하지 못한 점을 고려하면 대국민 홍보는 상당한 효과가 있을 것으로 기대된다. 소비자들이 음식물을 남기면 결국 소비자들에게도 피해가 발생된다는 점을 부각시킴으로써 소량배식 및 좋은 식단제 등을 통한 영업주측의 식문화 개선 정책 시도에 대한 소비자들의 오해와 불만을 완화시키는데 대국민 홍보가 긍정적인 영향을 미칠 것이다. 또한 전문가들은 보다 구체적인 남은 음식물 저감화 방안으로 '반찬선택제'와 '소량배식'을 꼽았으며, 남은 음식물 재사용 근절 방안으로는 '식당 내 남은 음식통 설치 의무화'를 통해 남은 음식이 식당 내로 재진입되는 것을 막을 수 있는 방안을 제안하였다. 이러한 방안들은 영업주와 종사원들의 실천의지를 전제로 식품접객업소 단위에서 적극적으로 적용할 수 있으므로 남은 음식물 관리를 위한 효과적인 방안이라 사료된다. '남은 음식 재사용 여부를 검증하는 과학적 기법 개발'은 남은 음식물의 재사용이 은밀히 이루어져 공개적인 지도와 개선이 어려운 점을 고려할 때 객관성과 과학적 근거를 토대로 한 가장 합리적이고 신속한 방안이다. 음식물에 혼입된 타액 효소의 검출을 위한 키트를 현장에 적용할 수 있다면 남은 음식물 재사용을 근절하는 가장 효과적인 해결책이 될 것으로 기대된다. 본 연구를 통해 제안된 남은 음식물 발생과 재사용 근절 방안들은 현재 한시적으로 운영되고 있는 남은 음식물 관련 정책의 향후 보완에 적용될 수 있을 것이다.

The purpose of this study was to improve the sanitary management of school foodservice. A survey questionnaire was administered to 153 dietitians from elementary, middle and high schools in the Daejeon area. The questions were categorized into four fields: 'General characteristics', 'Facility and equipment set up at the schools studied', 'Performance of CCP(criticai control point)s' and 'Reasons of barriers to HACCP(hazard analysis of critical control points) implementation'. The results were as follows. Most of the subjects were the dietitians of elementary school(56.9%), were university graduates(51.0%) and were in their thirties(58.2%). The average length of their career had been 5.8 years. The average ratio of students per dietitian was 1,163. The average ratio of students per full-time employee was 124. The ratio of self-operated management was 90.2 %. The CCP7(assembling and serving) received the highest performance score, while the performance score of CCP2(management of potentially hazardous foods) was the lowest. Eighty-four percent of the surveyed school foodservices did not have pre-preparation rooms. The school foodservice operations were not well equipped with hot/cold holding equipments. Self-operated management scored higher on almost all sections(CCP1-CCP7). Contracted management scored highest on CCP8. The higher the age and career of the subject were, the higher were all the CCP performance scores. The reasons of barriers to HACCP implementation were lack of understanding of standards CCP1 and CCP2, workers' lack of cooking knowledge, and lack of information about school foodservice.

The purpose of this study was to identify the relationship between the levels of foodservice management activities and job satisfaction of the dietitians in elementary schools. Out of 130 questionnaires distributed to elementary school dietitians in Incheon, 127 were returned and analyzed ($98\%$ response rate). The questionnaire included two multiple-item scales for measuring foodservice management activities and job satisfaction, respectively. All the items in the scales were coded 1 to 5 for 'certainly no', 'no', 'neutral', 'yes', and 'certainly yes' and grouped by using factor analyses. Most of the responding dietitians were working for schools in urban areas and have independently managed on-site kitchens. The 19 items on food service management activities were grouped into 6 factors and the mean scores of the levels of Personnel Hygiene Management, Education & Training, Sanitation & Safety Management, Menu Quality Management, Service Management, and Environment Management were 4.76, 4.26, 4.24,4. 05, 3.61 and 3.39, respectively. The 23 items on job satisfaction were grouped into 4 factors and the mean scores of the satisfaction levels of Systematic Environment, Job Duty, Job Condition, and Physical Environment were 3.38, 2.83, 2.53, and 2.08, respectively. Overall, the levels of food service management activities and job satisfaction were positively associated with a correlation coefficient of 0.254 (p > 0.01). In particular, satisfaction levels on job duty itself and systematic environment were positively associated with the levels of overall management activities. The results suggest that improving dietitians' job satisfaction could increase the levels of management activities of school foodservice dietitians, resulting in quality improvement of school food service.
