The purpose of this study was to evaluate the effects of HACCP implementation. The HACCP education was provided twice within one month to 20 employees of a contracted food service operation in Daegu. Critical control points (CCP) were determined based on food preparation processes: non-heating, preparation after heating, and heating. We evaluated the effects of HACCP implementation by checking microbiological quality, time and temperature at each of the CCPs during the receiving, preparation, cooking, and serving stages. After HACCP implementation, the biggest changes in microbiological qualities were in heated foods. At the cooking and serving stages, the microbiological qualities of heated foods improved to the standard levels. HACCP education helped employees ensure that the internal temperatures of the heated foods were kept higher than the standard (74 $^{\circ}C$) and the food holding temperature avoided the dangerous zone (5-6$0^{\circ}C$), thus lowering microbiological levels. At the serving stage, the microbiological levels of utensils also improved after HACCP education. This result strongly suggests that it is essential to educate employees in managing the temperature to treat foods safely. However, HACCP education didn't affect the microbiological levels of non-heated foods and foods prepared after heating, which continued to be higher than the standard. The reason for this was that poor microbiological quality seasonings were added to those types of foods. This indicates that seasoning factories as well as food service operations should implement HACCP to reduce hazards.

Compatibility of polymeric materials governs their suitability for nearly all potential applications. An aspect of compatibility that is frequently important for fluoropolymers is their ability to isolate fluids by serving as a barrier to mass transport. This property is commonly expressed as permeability. In ideal cases, both solubility and diffusivity are constant at any given temperature and so the permeability is also a constant.(omitted)

Rapid change of surroundings has been influencing the work environment for cooks, making it more convenient; however, there are still many difficulties to improve. Especially, cooks are exposed to lots of occupational diseases due to tension and pressure as well as noise, high temperature and humidity in their work place. This study examines cooks' operational exhaustion caused by cooking operation and cooking circumstances. The analyzed result shows the job fatigue related to the general features of the cooks(such as charged cooking part, types of engaged business, class of position, cooking career, and working hours). For example, pains on the neck, back, arms and wrist are mostly affected by the charged cooking parts. Effects related to the types of engaged business, backaches usually occurred in Catering, pains in shoulder from serving at hotels and eye-tiredness from meal serving. As for working hours, most of backaches occurred from over 13-hour-work, and pains in shoulder and eye-tiredness under 8-hour-work. Pains in legs, tiredness, and the change of weight do not have any relations withthe general features of the cooks statistically(p>0.05).

Student and dietitian reactions to a multicultural food service menu were studied. Food habits in a multicultural family could delay the acculturation of the children to traditional Korean food and could cause the isolation of children from the community. Also, Korean students need to be exposed to other cultures and foods because it can be a challenge to eat novel foods when students grow up. To help both multicultural and Korean children adjust to new foods, a multicultural menu was included in a school's food service. Students regarded the multicultural menu as access to another culture, but they felt that improvement of the food quality and menu diversity were required. The degree of satisfaction with the food quality, appearance, freshness, temperature, and menu diversity were all moderate. The multicultural menu was served as a single menu item or a combination menu item. The main dish single items - pasta, jajangmyeon, onigiri, hamburgers, rice and curry, kaupatmu, kaupatkung, and donburi - were liked, but nasi goreng was liked only moderately. The soup - based dish single item, tempura soba, was liked, while tomyum was disliked. The side dish single items - tangsuyook, Japanese donkatsu, baked sausage and potatoes, tandoori chicken, chicken britto, Vienna schnitzels, tender tortillas, and fried chicken wings - were liked. The desserts single items-sandwiches, pineapples, waffles, pizza, bread with strawberry jam, mangoes, and tacoyaki - were liked. The combination menus - Italian, Indian, and American - were liked, but the southeast Asian menu was the least favored. Acceptance of combination and single menu items were similar. Male students liked multicultural menu items more than female students in all categories. Approximately 60% of dietitians had experience serving the single menu items for multicultural food service. The appropriate serving times were twice per month. Dietitians guessed that 80% of the students liked the multicultural menu. The dietitians preferred serving American or Chinese foods to southeast Asian food. There were two difficulties in serving the multicultural menu, which were voiced as as lack of skill in cooking the items and improper cooking utensils and tableware for the items. Despite all the difficulties, the dietitians served the multicultural menu because it provided menu diversity, rather than for educational reasons.
