The purpose of this study was to determine the differences in perception of food hygiene and interest in dietary information among university students. A total of 550 college students from Seoul and the surrounding metropolitan area participated in this questionnaire using one-to-one interviews from September 20th to 28th, 2012. Three groups were classified according to level of awareness and practice of food safety. The highest education level of food safety was in the active-practice group (69.6%), with 58.0% in the want-practice group and 24.6% in the low-practice group. There were significant differences between the awareness and practice groups in terms of importance of food safety (p<0.001). Exactly 74.3% interest in food hygiene was measured in the active-practice group. Interests in dietary and food information were different between the groups: 71.4% for the active-practice group versus 24.6% for the low-practice group (p<0.001). Low-practice group showed the lowest scores for interests in organic food, pesticide-free food, low-pesticide food, slow food, LOHAS, healthy-functional food, nutritional labels, and expiration dates. In conclusion, appropriate levels of food hygiene and food safety education should be provided by the food industry according to perception of food awareness and practice of food safety.

The principal objective of this study is to determine the most appropriate methods to increase global recognition of Korean food. In service of this objective, interviews were conducted with Korean food specialists who worked for a Korean culinary educational institute in Seoul, as well as cooking experts who worked for restaurants in super deluxe hotels. The study was conducted for 10 days from Feb $21^{st}$ to March $2^{nd}$ in 2009. The results of the study were summarized and synthesized into some key opinions. First, one of the main concepts in Korean culinary education should involve the selection of a small group of the best members and training them to a world class level at a traditional HanOk style institute. Second, to establish a standard for trainee recruitment, we selected a group of members consisting of about 20 persons over the age of 18 years who had earned a degree or were scheduled to graduate from university chef training and had also worked for over 5 years in the field, additionally, foreigners were allowed to apply to the institute. The educational term is one year and some benefits, such as a fixed amount of subsidies to help in daily living, free dormitory housing a certificate of course completion, and an employment guarantee. Third, the educational program consisted of two stages one was the specialist course in which traditional foods were covered and the other was the menu development course, which dealt with the creation of new Korean foods. Fourth, unique programs, including specialized foreign foods experience halls or commission education, were instituted in an effort to raise the level of world recognition of the superiority of Korean food.

This study was conducted to compare solo eating perceptions and dietary behaviors in the Seoul and Gyonggi-do regions according to gender. The study focused on the dietary perceptions, solo eating, eating together, dietary habits, food intake patterns and 38 keywords pertaining to solo eating. Of 411 subjects, 207 (50.4%) were males and 204 (49.6%) were females. The biggest problem that respondents perceived in their dietary life was irregular eating. Women prepared meals more often than men (p<0.001) and ate more instant and frozen food than men (p<0.05). Both males and females missed breakfast most, and the amount of the population eating breakfast alone ranked second highest. Women had lunch alone more often than men, while men ate dinner alone more often than women (p<0.01). All respondents spent 5~15 min when eating alone. Women avoided excessive smoking and drinking more than men (p<0.001). Men related key words regarding solo eating with negative emotions such as 'lonely', 'boring', and 'feel sorry when I see someone eating alone in a restaurant' more than women. Conversely, women related more positive key words with eating alone such as 'free', 'joy', and 'my own time'. Dietary lives of Koreans have rapidly changed along with social changes. Our research findings will contribute to increased comprehensive menu development and HMR development in the foodservice industry.

The purpose of this study was to investigate a plan of middle/high school foodservice systems which could properly provide nutrition for juveniles' health. Questionnaires were developed and distributed to: 245 middle schools with 271 parents, 328 students, 180 teachers, and 345 administrators; 163 high-schools with 223 parents, 466 students, 179 teachers, and 163 administrators in Seoul and Kyunggi province. The results of this study were as followed. For the desirable feeding type as in-school meal plan, 62.2% responded to the current elementary school feeing type:10.3% responded to a lunch-box prepared at home; and 38.0% responded to free dining out type. For a feeding operation type, school administrators, teachers and parents favored the current school feeding systems in elementary schools with proportion of 68.2%, 47.7%, and 87.6% as respectively. Also, 20.3% of school administrators, 22.6% of teachers, and 6.9% of parents preferred contract management. A total of 27.6% of teachers, 9.2% of school administrators, and 3.7% of parents responded to a lunch-box prepared at home. There was a significant difference between the responses for establishing the main body of financial burden to solve the problem of financial burden which could be the most obstacle to bring middle/high school feeding system into operation. For the management of school feeding systems when brought into operation, 88.7% out of 470 responded schools and 89.9% out of 227 responded teachers reported that an expert should manage school feeding systems. For futuristic direction, an effective joint cooking type between schools which may be the way to solve the difficulties in securing the appropriate space and to decrease the financial burden, the problem of transportation for delivering feeding products, low quality of feeding, and sanitation can occur. Therefore, the distance between schools which operate a joint cooking system will affect as a major factor. Furthermore, concrete examination of plans for introduction of various types of school feeding and institutional devices for management system and supervision of operation should become a condition precedent.
