The purpose of this study was to investigate the foodservice employees' awareness and performance in sanitation and customers' satisfaction with sanitation in large sized restaurants in Korea. Sanitation inspections were carried out in 200 large Korean, Western, Chinese, and Japanese style restaurants, and in buffet-style restaurants in Daegu and Gyeongbuk province. Foodservice employees' awareness of sanitation and customers' satisfaction with sanitation were investigated by interviewing 317 foodservice employees and 205 customers. Results of the inspection of restaurants showed low performance in food handling, employees' hygiene (hygienic) practices, and in cleaning food processing equipment. Scores of the foodservice employees' awareness in Chinese style restaurants were significantly lower than scores of workers in western restaurants. Foodservice employees had low awareness of sanitation procedures used for food storage and cleaning of equipment in Korean, Chinese, and Japanese style restaurants. Foodservice employees had low awareness of equipment cleaning, inspection and food distribution in western style restaurants and of equipment cleaning and food handling in buffet-style restaurants. Foodservice employees at all restaurants had the lowest performance in terms of HACCP. This shows that HACCP application and recording have not yet been properly carried out at restaurants in Korea. Foodservice employees had low performance scores in food handling, vegetable disinfection and disinfection after hand washing. Research on customers' satisfaction with sanitation revealed a low rating of kitchens and foodservice employees at all restaurants. Customers had low satisfaction with servers and kitchen environments in Korean style restaurants with food, tableware, utensils and servers in western style restaurants; with food and kitchen environments in Chinese style restaurants with servers, tableware, and utensils in Japanese style restaurants and with kitchen environments and servers in buffet-style restaurants. Therefore, cleanliness of kitchen facilities and equipment, and hygienic food handling procedures by workers in restaurants are urgently needed.

This study investigated the microbial safeties and germination rates of five domestic sprout species(alfalfa, broccoli, clover, red cabbage, and red radish) grown from disinfected seeds. The 48 h germination rates of all seeds were over 90%, regardless of treatment. Seed total plate count(TPC) and coliform levels were reduced significantly(p<0.05) by treatment with 20,000 ppm calcium hypochlorite solution at $25^{\circ}C$ for 15 min, following FDA recommendations. However, after germination, all sprouts regardless of treatment exhibited bacterial counts of $10^7-10^8CFU/g$. Listeria monocytogenes was detected at $10^3-10^4CFU/g$ on germinated non-disinfected clover seeds at days 1, 2, and 5. In conclusion, although sprout germination from disinfected seeds potentially permits the growth of sprouts with lower pathogen counts, there were no significant differences in TPC or coliform levels between sprouts grown from disinfected seeds and control sprouts. Further work is needed to improve the microbial safety of cultivated sprouts and to find optimal conditions for seed germination.

The objective of this study was to evaluate and improve the microbiological quality of HACCP application in school foodservice operations. The microbiological quality of foods and utensils were evaluated two times at each critical control point (CCP) with 3M petrifilm in five Daegu elementary schools. Two processes were evaluated: Heating process and after-heating process. The CCPs of the heating process were receiving, cooking and serving temperatures. The CCPs of the after-heating process were personal hygiene, cross contamination avoidance and serving temperature. After the first experiment, 31 employees of five schools were classroom educated, trained on-site, and pre- and post-tested on HACCP-based sanitation with the goal of improving the microbiological quality of the foodservice. Scores representing knowledge of holding, thawing, washing, food temperature, sanitizing and food-borne illness increased after education. In the heating process, internal food temperatures in the first and second experiments were higher than 74$^{\circ}C$, the holding temperature in the first experiment was less than 6$0^{\circ}C$. In the second experiment, the serving temperature improved to a satisfactory level. The microbiological quality in the second experiment improved by decreasing the time from cooking to serving. In the after-heating process, the ingredients were boiled before being cut in the first experiment. In the second experiment, ingredients were cut before being boiled, improving microbiological quality. Also in the second experiment, cooking just before serving food improved its microbiological quality through time-temperature control. These results strongly suggest it is essential to measure microbiological quality regularly and to educate employees on HACCP continuously, especially time-temperature control and cross contamination avoidance in order to improve foodservice quality.

Halophytes are plants of saline habitats that grow under conditions that may vary in extremes of temperatures (freezing to very hot), water availability (drought to water logging) and salinity (mild to almost saturation). Halophytes may also face sudden micro-environmental variations within their habitats. In this study, we examine some of the factors that determine the ability of seeds of Artemisia fukudo to germinate when conditions are optimal for seedling growth and survival. Germination percentage was the highest at 77.5% when treated in 0% seawater and seedling growth was best in 0% seawater plug cell tray. Physiological quality (chlorophyll contents) and mean germination time were best in the condition in which seeds were treated with 0% seawater (control). Germination performance index in the control group showed the highest value to 3.8. Seedling growth, seedling vigor index in the length of seedling growth andthe relative growth rate were the highest values of 0.76 cm, 1.43, 0.0099, respectively.

The Lee and Carter method has widely used to forecast mortality because of the simple structure of model and the stable forecasting. The Lee and Carter method, however, also has limitations. The assumption of the rate of decline in mortality at each age remaining invariant over time has been violated in several decades. And, there is no way to include covariates in the model for better forecasts. Here we introduce Park, Choi and Kim method to make up for Lee and Carter's weak points by using two random processes. We discuss structural features of two methods. furthermore, for each method, we forecast life expectancy for 2005 to 2050 using South Korea data and compare the results.

The purpose of this study was to develop various nutrition education materials, including an animated CD, for day care center children and their teachers and in order to apply the nutrition education programs systematically. We evaluated the effect of the nutrition education programs on nutrition knowledge in the first year, and the effect of the nutrition education programs on nutrition knowledge, food attitudes and eating behaviors in the second year in day care center children. In the first year, nutrition education foundational materials, such as the animated CD-ROM, videotape, textbook, panels, posters, slogans, leaflets, picture disks, hand puppets, stickers for compensation and poster boards were developed. The subjects were 537 children (286 boys,251 girls) aged four to six years. In the second year, nutrition education materials, such as the animated CD-ROM and textbook were developed. The nutrition education group included 368 children (177 boys 191 girls) aged four to six years, and the comparison group consisted of 108 children (54 boys,54 girls) Regarding the nutrition knowledge test results in the first year, the pre-test mean of children was 6.82, however, the post-test mean was 11.35 and showed a significant increase (p < 0.001). Regarding the nutrition knowledge test and the food attitude test results in the second yew, the nutrition education group had significantly higher scores than the comparison group in a post-test (p < 0.001). For the eating behavior test results, the post-test means between the comparison group and the nutrition education group were not significant. The test results show that several months of nutrition education is not enough to improve eating behaviors. As a result, nutrition education has improved nutrition knowledge and food attitudes in day care center children but short-term nutrition education was not sufficient to induce a change in eating behaviors. To improve eating behaviors in day care center children, nutrition education programs must be applied to day care center children in addition to their Parents and Persistent education will have to be continued.

Objectives : In the present study, the effect of Kuwonsimsin-hwan (KSS) was tested in methotrexate (MTX)-induced immunosuppressed SD rats. Methods : Methotrexate was fed to white rats once a day for 4 days. After the immune responses of the rats deteriorated, dried extracts of Kuwonsimsin-hwan mixed in water was fed to the rats once a day for 14 days. We then measured the number of lymphocytes in peripheral blood and the percentage of B-cells, T-cells, CD3+CD4+T-cells, CD3+CD8+ T-cells and IL-2 productivity sampled from spleen and peripheral region. Results : (1) The number of lymphocytes and the percentage of T-cells and CD3+CD4+ T-cellsin peripheral blood increased significantly in the KSS group as compared with the control group. (2) The percentage of B-cells, CD3+CD8+ T-cells, and CD4+/CD8+ T-cells in peripheral blood were not different statistically. (3) The percentage of T-cells in spleen and IL-2 productivity of spleen cells increased significantly in the KSS group as compared with the control group. (4) The percentage of CD3+CD4+ T-cells in spleen increased in KSS the group as compared with the control group but without statistical significance. (5) The percentage of B-cells, CD3+CD8+ T-cells, and CD4+/CD8+ T-cells in spleen were not different statistically. Conclusion : It is concluded that Kuwonsimsin-hwan has immunostimulating effect on MTX-induced immunosuppressed SD rats.

Recently, 'happiness' has become a major issue of national level, exceeding the matter of personal issue. Especially, Korea has actually increased its GDP by focusing on the economic growth for decades, and now it has achieved the economic/technical development as an IT power. However, Korean people's satisfaction with life called 'happiness index' is moving back every year. Even though there have been continuous efforts to enhance the national happiness by mentioning it as an essential issue in the national level, there are not many researches related to it. This study drew measures to enhance happiness by extracting happiness factors and unhappiness factors of Korea through social network service. Especially, it aims to analyze, compare, and apply happiness factors and unhappiness factors of three countries such as the US, UK, and Brazil with higher happiness indexes than Korea. For this, through the topic modeling of text mining technique, postings including keywords about happiness and unhappiness were collected/analyzed from Twitter of Korea, the US, UK, and Brazil. The significance of this study is to discuss measures to increase happiness and to decrease unhappiness by mining/analyzing the actual public opinions about happiness and unhappiness in four countries like Korea, the US, UK, and Brazil by using the topic modeling. Through this, the quality of life of Korean people could be improved by suggesting measures to enhance happiness and to decrease unhappiness in the level of individual, family, society, and government.
