In this paper, we surveyed the actual utilization condition of chain stores of franchise systems and the customers' consciousness on chain shops and non-chain restaurants. The survey was conducted on 459 people either living or working in Pusan area and aged more than 4th grade in elementary school without sex distinction. The data analyses were made by way of frequency, percentage, Spearman rank correlation and Chi-square using dBastat 1.0 package of PC. The results of the survey are as follows. The survey indicates that respondents have the most experience of visiting chicken, hamburger, and pizza chain shops. Although the survey on the degree of preference between chain shops and non-chain restaurants indicates that men prefer non-chain restaurants and women prefer chain shops, the results are not so significant to conclude that there is a preference regardless of sex (N. S.): By ages, students and young group prefer chain shops and the aged group prefer non-chain restaurants (p< 0.05). The survey indicates that chain shops are proffered because of sanitary, quality, taste of foods and are not proffered because of simple menu and expensiveness. The survey indicates that non-chain restaurants are preferred because of distinctive taste of each restaurant and comfotableness, and are not proffered because of unsanitary and unkindness.

School lunch programs at middle schools have increased in quantity. However, the quality of them is in fact not enough to reach the satisfactory standard, especially in the aspect of environment of school meals. It is true that there seems to be little attention to the environment. In this study, degree of satisfaction about school lunch program was surveyed for students in one middle school. Focus of survey was sanitary condition about the dining room and classroom where they have lunch. First, in order to investigate the degree of satisfaction about their dining place, questionnaire was sent out to the students at one middle school in Seoul. Questionnaire was made with reference to previous research. Second, for the study on environmental sanitation, dropping bacteria (general bacteria) is measured in three parts of dining place (entrance, serving table, dining table). Petriplate film was exposed to the responsible places for 15 minutes and then cultivated at the temperature of $32^{\circ}C$ for 48 hours before counting the number of bacteria formed. For the statistical analysis, SPSS 12.0 was used. The results of the study show that students had more satisfaction in dining room service than in classroom service. Important factors for the meal program such as "taste of food", "amount of food per student", "state of keeping warm", "appearance of food", "diversity of menu", and "kindliness of feeding staff" had more points in dining room than in classroom. For the environmental and sanitary aspect, the result of dropping bacteria (general bacteria) in dining room and classroom showed that table (5.00) and fooddistribution corner (8.67) of dining room were cleaner than those of classroom (P < 0.05). Making a good environment for school feeding will have a positive effect on the improvement of satisfaction and sanitation of school feeding. There should be expansion of dining room service for the students.

The purpose of this study was to analyze employees' practice levels and knowledge of sanitation at school foodservice operations, to examine the sanitation conditions of current school foodservice, and to suggest an effective sanitary training program. A questionnaire survey was conducted on a total of 578 subjects and 501 reponses were made available for this study. The collected data was analyzed using SPSS of windows. The main results can be summarized as follows: Training through handouts was the most effective (53.2%) and lack of time caused by overwork (57.1%) made the practice of sanitation training difficult. The degree of employees' perceptions of the necessity of sanitary training programs was marked at 4.18 points. According to the foodservice employees' evaluation about the knowledge of sanitation concerning the sanitary training program contents, the area of environmental sanitation (96.3%) was the highest while food poisoning control (72.9%) was lowest. Foodservice employees' practice levels was ranked above 4 points (out of 5 points) in 9 areas. Practice levels of cleaning and disinfection management were highest while that of safety management was lowest. About the food service employees' practice levels of sanitation, the degree of practice and the application of knowledge was 4.39 points. There was a significantly positive correlation between the practice level of sanitation and sanitation knowledge(p<.01). Thus, educational material needs to be standardized in order to improve employees' sanitation practice level.

The number of covered carts selling snack foods along the streets are increasing in Korea and people enjoy eating foods at these carts. However there are only a few reports on the contamination or sanitary condition of the food carts. This study was performed to investigate the sanitary condition of food and water at the street food carts in the eight major areas of a city. Water and several kinds of food, kimbop(laver rollers) ddeokbokki(stir fried rice cake in hot pepper paste) oemuk(fish cakes) fish cake soup, and soy sauce were collected from four street carts from each of the 8 areas from June to August in 2001 The standard plate counts(SPCs) and coliform groups were examined according to the Food Code of Korea. The nufitness rates of SPCs of the samples were 0~15.6%: 15.6% in kimbop:6.3% in fish cake soup; and 3.1% in water samples SPCs were not detected in some samples. of ddeokbokki, oemuk and soy sauce. The unfitness rates of coliform groups were 0~62.5%; 46.9% in kimbop; 6.3% in ddeokbokki,;22.9% in oemuk 62.5% in fish cake soup; and 3.1% in soy sauce. Coliform groups were not detected in water sample The numbers and unfitness rates of SPCs and coliform groups showed increasing tendencies over time within a day. The higher the air temperature was the more increase of bacteriological growth was observed These results indicate that the level of bacteriological contamination of foods and water in the street carts should be monitored and strict inspection is necessary. There should be legal consequences for serving contaminated food to the public.

6 Central commissary and 2 conventional school foodservice operations were assessed in terms of time-temperature relationship and microbiological quality, and monitoring control methods were identified through hazard analysis during the phases of prodution and distribution. 2 conventional schools from Seoul and 6 commissary schools from Kyungkido were participated in the survey. Meals produced in central commissary were distributed to satellites, therefore delivery practices of foods were identified as critical. Microbiological test results for commissary and conventional schools revealed that microbiological quality of foods was mainly related to time-temperature management, types of food, and equipment sanitation not to the foodservice system used. Time-temperature profiles at temperature danger zone (7.2-60$^{\circ}C$) observed were to be related to the following sanitary practices: cooked vegetables were held at temperature danger zone for relatively longer delayed time (15-38$^{\circ}C$: 15-226 min, 7-60$^{\circ}C$: 75-226 min), and same results were observed for deep-fat fried cutlets (15-38$^{\circ}C$: 15-151 min, 7-60$^{\circ}C$: 33-151 min). Menu items with various ingredients and frequent contacts with hands and equipments during the production flow were held at temperature danger zone for longer delaying time than other menu items with brief prodution stages. Based on hazard analysis critical control points, microbiological quality was collectively affected by time-temperature relationships, equipment sanitation, proper cooking methods, and sanitary management competencies of dietitians. Microbiological test results of working equipments and surface of dishes and trays showed that immediate action should be taken. Cutting boards used in central kitchen were also showed similar results of potential dager of cross-contamination. Effective sanitary control methods were urgently needed.

This study evaluated the sanitary state of seawater and shellfish in Yongnam-Gwangdo area from January 2014 to December 2016. The sampling stations for sanitary survey in Yongnam-Gwangdo area were composed of 41 seawater stations and 5 oyster Crassostrea gigas stations. The samples were collected monthly at each station. Shellfish-borne disease is associated with bacteria and viruses in the presence of fecal coliforms. Bacteriological pollution levels of shellfish increase with seawater quality. Therefore, fecal coliforms are very important criteria for evaluating the safety of fisheries in coastal areas. The geometric mean and the estimated 90th percentile ranges of total and fecal coliforms for seawater were 1.8-11.7, 2.8-233.6, <1.8-6.7 and 1.8-100.2 MPN/100 mL, respectively. The range of E. coli levels for oysters was <20-1,300 MPN/100 g. Based on various standards, the sanitary condition in Yongnam-Gwangdo area was evaluated as follows: clean area (Korean criteria), conditionally approved area (US criteria) and class B (EU criteria).
