This study was undertaken to investigate dietary status, food habits, and nutritional knowledge of university students majoring in judo (n=239) and to evaluate the effect of dietary behavior on their athletic activities. Mean daily dietary intakes (3,854.0 kcal) were similar to mean daily energy consumptions (3,975.5 kcal). Average daily intakes of most vitamins and minerals were higher than Korean Recommended Dietary Allowances except for the intake of vitamin A. Self-confidence on judo affected dietary behavior of the subjects: Subjects who had more self-confidence on judo showed more interest in good nutrition and concerned more about foods which could promote their athletic activities. Many side effects were manifested after sudden weight control for judo competition during school days. Therefore, it is suggested that good education on nutrition is necessary not only for athletic students, but also for coaches and trainers of the students. Ten weeks of education on nutrition significantly improved both food habits and nutritional knowledge of the subjects. Food habits were positively correlated with self-confidence on judo. Therefore, it is suggested that improvement of food habits through good education on nutrition would be helpful to improve athletic activities of the students.

We tried to find out parents' satisfaction and needs for foodservice quality of the childcare centers with an intention of improving it. Self-completed questionnaires were randomly collected from the parents of children in 174 childcare centers around Asan and were analyzed. Most of respondents were mothers who were housewives with college degrees (69%) in their 30's (80%). They thought nutrition (50%) and food hygiene (43%) were the most important factors for decision. Eighty percent of parents recognized the strong relationship between foodservice quality and childrens' mental and physical development. Most centers (94%) were delivering menu notices home, so parents well recognized the center's foodservice situation and problems of their kids' eating habits. The parents' satisfaction scores were 3.26 out of 5-point scale. The biggest dissatisfaction was from no variation in menu, but remarkable appreciation was from the effect of foodservice on the correction for kids' unbalanced diet habit. They had demands for improvement of nutritious menu and professional nutrition teacher in charge of foodservice and nutrition education for children and also for parents.

The purpose of this study was to investigate the nutrient intake, eating behaviors and health-related lifestyles of Korean non-nutrition major college students after they took a nutrition course. The subjects were 40 male and 147 female students at a university in Inchon. The results are summarized as follows: Average height of male and female students was 176.2 and 162.0 cm, respectively. Average weight was 66.2 and 52.3 kg, respectively. Average intake of calories, protein, vitamin A, vitamin C, vitamin $B_1$, vitamin $B_2$, niacin, and Ca was lower than Korean RDA. Fe intake of female students was lower than Korean RDA. Most students have had dietary problems such as overeating, eating unbalanced meals, and skipping meals. More than 60% of the students skipped breakfast. The main reason for skipping meals was lack of time. Most students didnt exercise regularly. About 40% of the students took vitamin or mineral supplements. As for smoking and alcohol use, 11.3% of the students drank alcohol and smoked, and 74.2% of them only drank alcohol. More than 30% of the students drank alcohol once a week. Most students ate out twice a week, and chose their based on taste rather than nutritional value. The main reason for eating out was simply to enjoy a meal. More than 60% of the students ate at places in or around campus. After taking the nutrition course, intake of milk and other dairy products, vegetables, fruits and protein-rich foods increased in female students. For both male and female students, intake of fat, sugar, processed foods, soft drinks, fried foods and spices decreased. Therefore, nutrition education had effect on non-nutrition major students, suggesting that proper nutrition education encouraged healthy eating habits on the part of college students.

In the present study, we conducted in-depth interviews with school dieticians and nutrition teachers to determine the local foods they were aware of and their experiences with local foods. We also aimed to obtain more detailed measures for local food vitalization and suggestions for improvements. In-depth interviews were performed with 8 school dieticians and nutrition teachers, who stated that local food vitalization was needed for school food services, because it could be a foundation for securing safefood products, student healthi mprovements, environmental protection, and the establishment of a general consumption market. However, they were aware of a higher number of disadvantages than advantages in school situations and indicated the deterioration of the quality of food products as the biggest disadvantage. The most-suggested measurement items for local food vitalization in schools included improvement of the food distribution system, expansion of education, information sharing, prevention of monopolies, improvement of food-product quality, and mass production. In addition, it was suggested that school dieticians and nutrition teachers should invest efforts in the development of excellent recipes and varied diets utilizing local foods. Therefore, system supplementation is urgently required in order for school food service officials, and consumers, to efficiently introduce and vitalize local foods. It is also necessary to foster an environment that encourages trust-based relationships with producers to maximize the effect of system supplementation. This would be the foundation for improving the health of students, improving food-service quality, nutrition management, and vitalization of the regional economy in the future, and will positively affect students' food consumption patterns even after they become adults.

This study was carried out to investigate the effect of nutritional knowledge on food habits of male employees in Korea. A questionnaire was developed and distributed to 265 male employees of Seoul and Kyunggi area in Korea. The data were analyzed by t-test and ANOVA using SPSS (ver 12.0). Regarding the general aspects of subjects, the highest percent of ages were between the age 21-30 year old. Most respondents were graduates from a university. About twenty percent of male employees' average income was 1-2 million won per month. Most of their families were nuclear families. Eighty three percent of the respondents did not experience any education on nutrition and obtained food and nutritional information from television and internet. The respondents had a high level of perceived knowledge (86.2%); yet, the accuracy of knowledge was lower than the perceived knowledge (72.31%). Regarding the nutritional knowledge, single groups showed a lower score than married groups and groups living with family. Higher nutritional knowledge correlated with higher educational levels, among man in their twenties and thirties. With regards to their eating habits, the frequency of food intake within a weekly period was significantly different; a large percentage of respondents had high frequencies of instant food, alcohol consumption, and smoking. The higher scores regarding dietary habits were for age groups ranging from 41-60 year old, married individuals, nuclear family groups and educational groups with university degrees. Based on the results of this study, male employees have problem concerning food habits in that they are unbalanced and have a tendency to skip meals. Therefore, for the improvement of nutritional status and eating behavior of male employees, the importance of nutrition needs to be emphasized with proper nutritional education programs.

BACKGROUND/OBJECTIVES: The current South Korean government policy on food irradiation technology should be reformed based on an in-depth investigation of the communications aspect, because the issue is no longer of a technological nature, given the proven safety and efficacy of the processes. SUBJECTS/METHODS: The target population of the education program consisted of elementary, middle, and high school students attending 310 schools in South Korea (2013: 63 schools, 2014: 104 schools, 2015: 143 schools). Data subjected to analysis were 13,327 pre-education and 12,641 post-education questionnaires received from 7,582 elementary, 2,671 middle, and 3,249 high school students who participated in the education program from May 2012 to April 2015 (n = 12,831), after the exclusion of inadequately filled-in questionnaires. RESULTS: Analysis of the three-year educational effect trend was conducted by comparing levels of variables before and after food radiation education. The analysis yielded the finding that the post-education levels were significantly higher for all variables. That is, for interest in education, perception (necessity, safety, subjective knowledge, and information acquisition), objective knowledge, and attitude, with the sole exception of objective knowledge in 2013. CONCLUSIONS: Given that post-education levels of perception, knowledge, and attitude concerning irradiated foods increased considerably compared to pre-education levels, behavior change should be induced by providing continuous education to enhance, these primary variables.

The objective of this work was to study the effect of mixed culture solid substrate fermentation of C. tropicalis ZD-3 with A. niger ZD-8 on detoxification of cottonseed meal (CSM), and to investigate the effect of fermentation period, proportion of CSM in substrate, sodium carbonate, minerals and heat treatment on the reduction of free gossypol levels during mixed culture solid substrate fermentation of CSM. Experiment 1: Three groups of disinfected CSM substrate were incubated for 48 h after inoculation with either of the fungi C. tropicalis ZD-3, A. niger ZD-8 or mixed culture (C. tropicalis ZD-3 with A. niger ZD-8). One non-inoculated group was used as the control. Levels of initial and final free gossypol (FG), CP and in vitro CP digestibility were assayed. The results indicated that mixed culture fermentation was far more effective than single strain fermentation, which not only had higher detoxification rate, but also had higher CP content and in vitro digestibility. Experiment 2: CSM substrates were treated according to experimental variables including fermentation period, proportion of CSM in substrate, sodium carbonate, minerals and heat treatment, Then, the treated CSM substrates were inoculated with mixed culture (C. tropicalis ZD-3 with A. niger ZD-8) and incubated at $30^{\circ}C$ for 36 h in a 95% relative humidity chamber. After fermentation ended, FG and CP content of fermented CSM substrate was assayed. The results showed that the appropriate fermentation period was 36 h, and the optimal proportion of CSM in substrate was 70%. Addition of sodium carbonate to CSM substrate was beneficial for fermentative detoxification. Heat treatment could facilitate fermentative detoxification, and supplementation with minerals was instrumental in reducing gossypol levels during mixed culture solid substrate fermentation of CSM.
