This study was carried out to develop the computer-assisted Hazard Analysis and Critical Control Point (HACCP) program for a systematic approach to the identification, assessment and control of hazards for foodservice manager to assure the microbiological quality of food in hospital foodservice operations. Sanitation practices were surveyed and analyzed in the dietetic department of 4 hospitals. Among them, one 762-bed general hospital was selected as standard model to develop computer-assisted HACCP program. All data base files and processing programs were created by using Foxpro package for easy access of HACCP concept. HACCP program was developed based on the methods suggested by NACMCF, IAMFES and Bryan. This program consisted of two parts: the pre-stage for HACCP study and the implementation stage of the HACCP system. 1. Pre-stage for HACCP study includes the selection of menu item, the development of the HACCP recipe, the construction of a product flow diagram, and printing the HACCP recipe and a product flow diagram. A menu item for HACCP study can be selected from the menu item lists classified by cooking methods. HACCP recipe includes ingredients, their amount and cooking procedure. A flow diagram is constructed based on the HACCP recipe. The HACCP recipe and a product flow diagram are printed out. 2. Implementation of HACCP study includes the identification of microbiological hazards, the determination of critical control points, the establishment of control methods of each hazard, and the complementation of data base file. Potentially hazardous ingredients are determined and microbiological hazards are identified in each phase of the product flow. Critical control points (CCPs) are identified by applying CCP decision trees for ingredients and each process stage. After hazards and CCPs are identified, criteria, monitoring system, corrective action plan, record-keeping system and verification methods are established. When the HACCP study is complemented, HACCP study result forms are printed out. HACCP data base file can be either added, corrected or deleted.

This study was carried on the analysis of food and nutrient intake for elementary school foodservices in Seoul. The survey was conducted through the 200 menus submitted by the 5 elementary schools in Seoul. Energy and all nutrient intakes exceeded the Recommended Daily Allowances of Koreans. Carbohydrate provided 56.32% of total energy intake; protein accounted for 16.06%; fat provided 27.62%. Total intake of food was 549 g on the average, which consisted of 90.04 g cereals, 130.17 g vegetables, 31.56 g meats, 21.63 g fishes and 200.00 g milks. The basic menu patterns were Rice+Soup (or Stew)+Kimchi, and 2 other side dishes including milk. These data underscore the necessity of developing the 'Standard Menu' for elementary school foodservices.

The main purpose of this study was to observe the effect of school lunch program on dietary habits of elementary school children and their food preferences. A questionnaire survey was conducted on 785 children and their mother in ele-mentary school with and without school lunch program. The results of this study can be summarized as follows: 1. 91.1% of subjects were eating rice for breakfast menu and 12.2% of subjects were skipping breakfast every morning. 2. Most of the children preferred fruits, ddugboggi, ice cream, fritter, cookie, bread, beverage and hot dog for snacks. 3. Despite of its restrictive practice, the school lunch program proved to be contributory to the improvement of children's food intake habits, table manners, keeping social order, sanitary consiousness, gratitude for their parents. 4. Children preferred kimbap, bokumbap and hamburger for main dish, fish jelly soup, brown seaweed soup and bean-sprout soup for soup, animal food for side dish and frying saute for cooking methods. 5. Most of the children disliked crown daisy, green pepper, mushroom, green onion, onion, dropwort, soybean and carrot for their food materials.

To find out the reference data of the school food service system, I serveyed four primary schools in Seoul, Korea and Nara, Japan respectively. The school children and their parents of whom arbitrary selected two classes among each primary school, were taken the questionaire about the present school food service system and their favorate food. The results were as follows; 1) 74.8% of Korean and Japanese children, and 92.5% of their parents were in favor of school food service. 2) Korean childrin wanted more amount of food and less salty taste. 3) Korean and Japanese children and their parents believed that the school food service system correct children's unbalanced diet. 4) Korean children wished more kinds of foods, western-styled cooking and that the food would be served in warm state. 5) Korean parents wanted that school food service system should be natural and better quality food material, and teacher should educate good eating habit. 6) Korean school children prefer yogurt, cuttle-fish, chicken, bean-curd, tomato, orange, dried laver, sweet potato, pine-mushroom in each food group. In conclusion, school food service system should be enough to meet children's good nutrition status, and the menu would be selected with consideration of children's preference and Korean traditional diet habit. Good table manner and eating all kinds of foods should be targht by school food service system as well as preparing good quality of food.

Consumer's perceptions of the quality of food and food-related servcie were surveyed through questionnaires by 672 adults randomly selected from 20 industrial foodservice in Pusan Kyeung Nam area. Data from consumers were analyzed by using SPSSPC+ program in terms of 2-test, oneway ANOVA, t-test. The results are as follows: 1) Among the food characteristics, the mean rating for temperature of food was 3.18 over 5, for quality of food vs. food price 2.97, for fresshness 2.96, for taste 2.86, and for combination of colors 2.73; 2) In the food-related service, the mean rating was 3.20 for cleanliness of dishes, 3.18 for quality of dishes, 3.01 for varity of food items, 2.95 for courtesy of employees, and 2.57 for availability of favorite food. 3) Self-operated foodservice showed higher mean ratings in nutrition of food, quality of food vs. food price, and availability of favorite food than does the contracted one. 4) The rice (85.0%) and the kimchi (81.4%) were right in amount, but the soup (42.5%) and the side dish (49.0%) were not enough. 5) In seasoning of food, 45.2% of the respondents agreed that the salty taste and the amount of MSG were just right. However, 38.0% and 37.9% of them responded that the salty tast was strong and the amount of MSG was much. 6) The respondents mostly required the improvement of the taste of side dish, nutrition of food, sanitation of food, and variety of menu items.

The purposes of this study were to: 1) measure the levels of job satisfaction with five facets of a job: the work itself, promotion, pay, supervision and co-workers, 2) investigate the degree of job characteristics inventory which employees perceived, 3) investigate relationships between job characteristics and job satisfaction levels of the employees in hospital foodservice, 4) measure the levels of organizational commitment and investigate its relationships between job satisfaction and job characteristics, 5) investigate the relationships between job performance and job satisfaction, job characteristics of the employees in hospital foodservice. The questionnaire was developed based on modifying Job Descriptive Index developed by Smith, Kendall, Hulin and Job Characteristics Inventory developed by Sims, Szilagyi, Keller and Affective commitment Scale developed by Meyer and Allen. Subjects consisted of 76 employees in hospital foodservice. Data were analyzed for frequency, means, ANOVA, Duncan multiple range test, and pearson correlation using SAS PC Package. The results of this study were as follows. 1) Most of the respondents were 41 years up(39.5%) and married (92%). High school graduates were 59.2%. 10 years working experienced employees were 35%. 2) A majority of the respondents(44.7%) ranked work itself as the most important aspect. 3) They were the most satisfied with co-workers. 4) Satisfaction with work itself, wage, and supervision were found significantly related to age(p<0.05). 5) Task identify was the most prevalent job characteristics and then task identity. 6) Satisfaction with co-workers were found significantly related to job variety(p<0.05). Satisfaction with supervision and promotion were found significantly related to friendship(p<0.05). 7) Job satisfaction have not correlation with job performance. Satisfaction with supervision, co-workers were positively correlated with organizational commitment(p<0.01). 8) Job characteristics of dealing with others were positively correlated with job performance (p<0.05). Job characteristics of variety, autonomy, task identity were positively correlated with organizational commitment(p<0.05, p<0.01).

The school food service system has been an important national policy in Korea. To find out the reference data of the school food service system, we surveyed four primary schools, one middle school, and one food service center in Nara, Japan. The results are as follows; 1. The school food service was carried out in 99.4% of primary school children and in 82.5% of middle school students. 2. The central commissary school food service system was utilized at 49.0% of primary schools and 68.5% of middle schools. 3. The expense of the system is supported partially by the student's parents and partially by the government, of which the support rate was noticed by the law of school food service. 4. The dietary content of school food service was laid down by 'The rule of the operation basis of school food service'. The menu was chosen by the 7 kinds of stepwise meetings. 5. The teachers emphasized on the food etiquette, the appreciation to the food and the personal relationship during meal, as well as on the nutritional balance. 6. We found other problems in Japanese food service system, such as the sanitary problems, the problems of the new tableware, and whether the central kitchen had less advantage than the individual school kitchen. We can conclude that the school food service system is becoming the essential part in school education, and hope to design not only economical but also educational system in Korea, with the consideration of Japanese system.

The purposes of this study were to: (a) identify college students' patronage behaviors, (b) develop an instrument measuring the attitudes of University Students towards university foodservices management practices, (c) determine university students' attitude towards the four types of university foodservices, and (d) provide recommendations on marketing strategies for university foodservice. Questionnaires were hand delivered to 600 Yonsei University students by designated coordinators. A total of 549 questionnaires were usable; resulting in an 93.3% response rate. The survey was conducted between November 28 to December 4, 1995. Statistical data analysis was completed using the SAS Programs for descriptive analysis, T-test, χ2 test, ANOVA, Factor Analysis and Stepwise Multiple Regression. Most (88.3%) of students were patronizing university foodservices for lunch. Underground student foodservice (40.1%) and Restaurants outside the campus (33.7%) were primarily used for lunch and dinner respectively. Eighty six percent of university students had 1 to 2 meals per day at university foodservices. The reasons given by students for patronizing university foodservices were as follows: location, time, price, menu, taste. Most of the respondents were least satisfied with hygiene, taste, menu and atmosphere. Data indicated strong support for eight priori dimensions in terms of food, menu, atmosphere, hygiene, employee attitude, facilities and convenience. After the factor analysis, price, fast service and foodservice location attributes were rearranged, combined and created a new dimension called as 'access'. Three dimensions in terms of menu, hygiene, convenience were important to students although performance was perceived as poor through importance-performance analysis. Most of students were not satisfied with all four types of university foodservices. In terms of food quality and price which university foodservices offer, most of respondents were moderately satisfied. According to multiple regression analysis, 93.31% of the variance respondents' satisfaction score could be explained by food, menu, price, atmosphere, hygiene, employee attitude, facilities, and convenience dimensions.

This study was undertaken to investigate the dietary behavior and sugar intake of korean school children. The subject were 131 school lunch program children and 149 non school lunch program children lived in Soung Nam city. Sugar intake, food intake, dietary behavior and anthropometric measurement were studied through personal interview using 24-hour recall dietary data and records. Total daily energy and nutrient intake of children were higher than RDAs except for intake of Calcium and vitamin A. The nutrients intake of school lunch program children were significantly higher than that of non school lunch program children (p〈0.05). The range of daily sugar intake was 10 g to 220 g and the total daily sugar intake was 63.0±37.4 g. Sugar intake of school lunch program children (51.4±25.7 g) was significantly lower than non school lunch program children (73.1±42.9 g) (p〈0.0001). The more sugar intake increase more intake of Energy, Fat and Carbohydrate. The result of stepwise multiple regression analysis using the sugar intake of children as dependent variable, energy, vitamin B2, protein, niacin, calcium school lunch program, education of fathers are significant explanatory variables, explaining 44.8% of variation. Result of this study suggest that school lunch program is desirable for good dietary behavior and decreation of sugar intake of school children.

This study researched microbial change of quality according to the various phases of product flow of cooked pea and rice, cold cucumber and seaweed soup, soybean sprouts japchae feeding urban type of a commissary school and a satellite school in Daejeon area, also it suggested the possibility that the central commissary foodservice system can be established and utilized more developmental to identify its food of variation of temperature and state of safety unitl 3 hours after cooking for the case of delay of distribution and holding because of the satellite school of geographical location and traffic problem. The critical Control Points identified for each category of menu items were: Boiled pea and rice: inadequate distribution, holding and storing before assembly; Cold cucumber and seaweed soup: pre-preparation and post-preparation after cooking; Soybean sprouts japchae: Pre-preparation, post-preparation and storing. As the result of observation of the variation of temperature and microbial safety according to the delay of distribution and holding for each food, all of them were relatively safe until 3 hours after cooking, but cold cucumber and seaweed soup being stored for 3 hours, the value of E. coli is 103 CFU/g. The variation of temperature was more extreme in soybean sprouts japchae than cooked pea and rice and cold cucumber and seaweed soup. It was proved that the stainless container was excellent and that adequate holding container should be used.

A study has been performed on the cockroach knowledge and perception of managers, employees and consumers, and the cockroach control management in food service institutions. A total of 759 subjects including 101 managers, 293 employees and 365 consumers was surveyed in Seoul and Pusan areas from July 1994 to September 1994. The results obtained are as follows: The mean rates of the cockroach knowledge (i.e. 62.26/100.0) and perception (i.e. 23.67/30.0) of the consumers were significantly (p<0.001) lower than those of the managers (i.e. 68.87/100.0 and 25.30/30.0, respectively) and the employees (i.e. 69.09/100.0 and 26.99/30.0, respectively). In the cockroach detection rates, however, much higher rate was seen in the consumer group (i.e. 79.5%) than the manager (i.e. 43.3%) and the employee (i.e. 48.5%) groups. Forty and seventy percents of the subjects have suffered from allergies and nuisance by cockroaches, respectively. The cockroach control was performed by 75.5% of the food service institutions and 70.8% of them contracted with pest control operators to reduce the cockroach populations. The cockroach control methods of the operators were aerosol (40.7%) and insecticidal baits (30.5%). Only 33.7% of the institutions had the budgets for the cockroach control. For public health, the managers and the employees of the institutions need to be educated about cockroaches and hygiene. Also, it is suggested that cockroaches be regularly controlled by professional pest control operators.

Customary usage of oil at homes and rancidity of edible soybean oil by cooking frequency at homes and mass meal services were investigated. 80% of house wives bought the cooking oil by 1.8 f unit container and 70% of them read either the manufactured date or explanatory note for use. 85% of house wives kept oil in the storage case under sink or in the pantry chest, and 80% of oils were used once or twice and 20% used three times for cooking. Acid value(AV), iodine value(IV), peroxide value(POV), carbonyl value(CoV) and thiobarbituric acid value(TBAV) of fresh soybean oil were lower than standard level. In the rancidity by cooking frequency, the acid value, peroxide value, carbonyl value and thiobarbituric acid value increased significantly when oil was used once and iodine value decreased significantly when used once and twice at both mass meal services and homes. The level of the acid value, iodine value, carbonyl value and thiobarbituric acid value of oil used at mass meal services did not show significant difference from those of oil used at homes. But, the peroxide value of oil used thrice at mass meal services was significantly higher than those of homes.

This study was conducted to assess the acceptability of the desirable serving temperatures of soups by evaluating the sensory characteristics of Radish Clear Beef Soup, Meat Pot Stew, and Chinese Cabbage Beanpaste Soup used in the Foodservice Establishment. 1. Taste revealed a better acceptability under a high temperature than that under a low temperature in three soups. 2. The aroma of Meat Pot Stew, Chinese Cabbage Beanpaste Soup showed a significant difference for each temperature, and especially, Chinese Cabbage Beanpaste Soup showed a better sabory aroma at 80℃~85℃. 3. Meat Pot Stew showed little significant differences in color and in its change among three soups. Chinese Cabbage Beanpaste Soup did not make any change of color at both 35℃~40℃ and 50℃~55℃. 4. In a Meat Pot Stew case, appearance conspicuously changed at 35℃~40℃, which resulted in losing appetite. Three soups showed a good response above at 65℃ and a very poor response at below 55℃. 5. Radish Clear Beef Soup, Meat Pot Stew, Chinese Cabbage Beanpaste Soup showed a tender texture at above 80℃, 65℃ and 50℃. 6. Chewiness showed a good acceptability from 50℃ to 80℃ in Radish Clear Beef Soup, Chinese Cabbage Beanpaste Soup cases, but only in the case of Meat Pot Stew showed good response at 80℃~85℃. 7. In cases of Radish Clear Beef soup, Meat Pot Stew, bland and stinking aroma, and aftertaste were increased remarkably in proportion as temperature was lowered. In case of Meat Pot Stew, especially, it turned out to be almost impossible to eat at 35℃~40℃. 8. In cases of Radish Clear Beef Soup, Chinese Cabbage Heanpaste Soup, overall acceptability at 65℃ was comparatively good but aroma and taste at below 65℃ was so bad that there was the eminent tendency to avoid tasting.

The purpose of this study was to evaluate food sanitation training program for the improvement of food service operation in day-care centers. Subjects consisted of 55(experimental) and 25(control) foodservice employees and 33(experimental) and 20(control)directors. The results of this study can be summarized as follow: 1. The majority of child care directors(55.0%(control), 46.9%(experimental)) received food sanitation education but 70% of control and 75.7% of experimental group did not conduct any practical sanitation training for employees. 2. The employee's food sanitary practices of control and experimental did not show any significant difference at the pre-test level but only the experimental group showed a significant improvement at the post-test level. 3. The sanitary knowledge of food service employees between two groups did not show any significant difference at the pre-test level, but a significant knowledge improvement was observed at the post-test level such as food poisoning concepts and sanitary equipment maintenance only in experimental group. 4. Dicrectors' sanitary practices affected the employees' sanitary practices but directors' food sanitary knowledge did not have much influence on the employees' knowledge.

Central commissary school foodservice operations' practices and their dietitians' job duties were assessed and compared with those of their counterpart of conventional school foodservice operations to find out strategies for early settlement and better management for commissary system. Survey qestionnaires consisted of general background, employees' work schedule and dietitians' job duties. 12 commissary schools(out of 22 existing in Korea) and 77 conventional schools from Kyungkido were participated in the survey. The results of this study can be summarized as follows: 1. Central commissary school foodservice was presently utilized at 5 schools from islands type, 11 schools from rural type, and 6 schools from urban type, consisting total of 22 commissary schools, and 52 satellite schools. 2. Dietitians were evenly employed with their experiences, 55.5% were those with less than 2 years of experience, 44.6% were those with more than 2 years of experience. 3. Commissary schools employed more full-time empolyees(1.8±0.7) than conventional schools(0.3±0.5), however as far as the production capacity was concerned, only the part-time employees played significant roles(p〈.01). Regardless of the number of students, an absolute number of full-time employees were employed, and their duties were not carried out efficiently. The part-time employees of commissary schools performed more loaded work compared to their counterparts in conventional schools. 4. Out of the dietitians' foodservice duties, 'basic food service production(3.9±0.7)' were carried out adequately, whereas 'nutrition education and advertisement(2.5±0.6)' and 'administrative affairs and information related duties(2.8±0.9)' were not. In order to enhance their working capacity, systematic organizational reforms are imminent. 5. Survey results also showed that dietitians performed less duties at satellite school than at the central commissary. This indicates more systematic foodservice management practices are urgently needed.

Hospitalized patients' perceptions of the quality of hospital foodservice and their importance were surveyed through questionnaires by 820(men 435, women 385) hospitalized patients in Seoul. The results are as follows: Most respondents agreed with the following foodservice characteristics that meals arrived exactly the same time every day(74.6%), cleanliness of dishes(64.9%), employees leave food within reach(60.2%), and employees who bring meals are cheerful(58.7%). Only 34.2% of respondents agreed to variety of menu; 12.9% of respondents viewed these foodservice characteristics as important in selecting a hospital; cleanliness of dishes(66.4%), variety of menu(55.0%), and varying food item combination(45.9%) were considered important by respondents; appetite, mood, and atmosphere of ward were positively correlated(p<0.001) with rating of the foodservice characteristics, but length of hospitalization was negatively correlated(p<0.001) with them; familiarity with cooking method, varying food item combination, cleanliness of the dishes, and foodservice employees' pleasant greeting were positively correlated(p<0.001) with rating of the taste, nutrition, and fresshness of the food characteristics.

Hospitalized patients' perceptions of the quality of hospital food and their importance were surveyed through questionnaires by 820(men 435, women 385) hospitalized patients in Seoul. The results are as follows: Men rated the size of food portion as being smaller, compared with women. The mean rating for nutrition of food was 3.24, freshness 3.15, taste 2.88, temperature 2.82; Among the food characteristics, nutrition was considered important by largest percentage(75.5%) of respondents, the taste ranked second(74.4%), and freshness was 62.2%; Appetite, atmosphere of ward were positively correlated(p<0.001) with rating of the taste, nutrition, and freshness, but length of hospitalization was negatively correlated (p<0.001) with them; Multiple regression analysis showed that appetite made the greatest contribution and length of hospitalization made the second greatest contribution. The third was atmosphere of ward, and the forth mood condition.

This study was conducted to evaluate the industry foodservice management practices in Pusan Kyeung Nam provinces and to suggest the guideline for the effective foodservice management. Questionnaire survey method were used in this study. Questionnaire were administered to 307 dietitians in Pusan Kyeung Nam. Data were analyzed for frequency, percentage, and χ2-test using SPSS-X Package. The results are as follows: 61.7% of industry foodservice establishment serviced foods over three times a day and 18.0% of them were less 500 won in the cost of food. 64.5% of the dietitian had less 3 years experiences, and they are not fully performed the effective management in nutrition education, job design and utilization of standardized recipes. Equipped facilities in surveyed foodservice operations were assessed as the insufficient condition, especially, efficient facilities such as a cutting machine were scarcely make up.

Unit price of meal provision in industrial foodservice differs with each business. It is believed that menu management work, contents of menu, and nutrition supply performed by dietitian are different with unit price of meal provision. In this sense, purposes of this study are to examine meal management work and contents of menu, by food cost, at industrial foodservice in Taegu, Kyungbuk area and to evaluate variety of menu and nutrition supply. Results of the study are as follows: 1. Average number of side dishes provided at meal, including Kimchi, was 2 at low unit price, 3.0 at middle unit price and 3.1 at high unit price. 2. Possession ratio of account books using for menu management was low. 3. With regard to kind of menu, high unit price was most various and showed more various, compared to low unit price, especially in cooking oil-used cook methods such as broil, pan-fried food, fry, and roast. 4. High unit price was found as the highest in kind of used food and supply volume. 5. Sugar, Mineral, Vitamine, and Protein were satisfied with standard food content, but fat and calcium were not. 6. Supply volume of food was positively correlated to supply volume of nutrient, but kinds of cook methods and food type were not correlated to that of nutrient.
