The salt concentrations of soup were 1.127 % in average. S. H. U. (scale of hot taste) of soybean sprout soup and spinach bean paste soup ranged between 12,500 and 47,500 equivalent to oleoresin capsicum content of 1.990${\sim}$5.911 (mg %). 4.

The objective of this study was to investigate parents' behavior and attitudes regarding their kids' snacking and dietary life education. A survey was conducted with the parents (N=412) of elementary students from seven provinces, includeing Seoul, Busan, Daegu, Kwangju, Gyungnam, Chungnam, and Kangwon. Kids' snacks consisted mainly of purchased foods rather than homemade foods. Parents' main concerns regarding kids' snacks were nutrition (44.9%), taste (24.3%), and safety (23.5%). Over 50% of parents checked food labels, especially expiration date (96.4%), food ingredients (49.5%), and food additives (33.5%). The snack items frequently provided to kids were fruits (62.8%), milk (55.5%), bread (47.1%), and snack items (23.3%). Parents responded that the amount of their kids' snacking was adequate (47.8%), small (33.7%), or large (18.2%). The results show that more research is needed regarding the adequacy of kids' snacking, considering that 15.7% and 22.4% of the children ate more and less, respectively, than their daily energy requirement. 76.5% of the parents performed home education regarding their kids' dietary habits, especially on the topics of 'balanced diet' (83.9%), 'healthful food' (53.7%), and 'eating three meals a day' (40.2%). Parents obtained dietary information from TV (65.2%), internet (12.0%), and newspapers (7.0%). From this study, we found that parents perceived their kids' snacking behavior correctly, and considered home-education for their kids' dietary habits positively. However, the information resources were limited, which makes it necessary to develop parents' education programs.

Changes in social, economical, and cultural environments affect the meal practices of children. The transmission of traditional Korean food culture is very important because it presents not only a well-balanced diet but also contributes to shaping identity. The purpose of this study was to investigate elementary school students' present meal practices and views, as well as demands on traditional food culture education to reflect future educational plans. Half of the students ate breakfast everyday and 72% ate a traditional Korean style breakfast. About 38% of the students participated 2-4 times per week in meal preparation and 34% participated in clean-up after the meal once a day. Although 6th graders had greater skills in basic cooking, they tended to be more passive upon applying their skills in daily meal practice. For traditional food culture education, 89% of the experienced and 86.2% of the inexperienced groups agreed on the necessity of traditional food culture education. Students attained traditional food culture knowledge through Silgwa, practical coursework within the curriculum, and by teachers leading classes. They were also educated by parents, mass media, and books outside of school. The preferred methods of class teaching were lecture and experiential learning. The preferred subjects to learn were 'cooking classes based on taste development', 'learning food ingredients through vegetable growing', 'traditional Korean food manners', and 'traditional Korean food culture and seasonal foods' as well as nutritional education. Fifth graders had more positive attitudes towards meal practices and traditional food culture education. Traditional Korean food culture and nutrition education should be integrated and developed into regular subject curricula to improve children's meal practice and inheritance of traditional food culture.

An IPA model was used to evaluate customer service encounters at a large food court; also the gaps between importance and performance from were also evaluated from both perspectives. The findings of this study will be applied in order to improve service quality at various large food service operations. A total of 298 customers from a large shopping mall food court completed the study questionnaire, asking them to evaluate the important and performance attributes of service. Seven underlying dimensions were identified and labeled by factor analysis: factor 1 was "safety": factor 2 "time": factor 3 "atmosphere": factor 4 "quality of food": factor 5 "menu attributes": factor 6 "comfort": and the last and seventh factor was "comprehension". As a result of IPA analysis the overall mean scores between the importance attributes and performance attributes showed significant differences by independent t-tests(p<0.001). Quadrant I was classified with unnecessary items including interior design, proper lighting, suitable chairs, and proper room temperature. In quadrant II thirteen variables showed high scores for both importance and performance, such as various menu choices, hygienic food, dishes, chairs, food court, kitchen, and employees; proper ventilation, employee kindness, waiting time to order, and received food; automatic system for ordering-serving. Quadrant III included eight variables identified as low priority, including appearance of food, nutrient content of food, proper portions, new menu, proper music, proper location of cashier, services for children and efficiency of movement. In quadrant IV six variables were included as areas to focus management's efforts, such as food taste, proper food temperature, use of safe food materials, maintenance of food quality, existence of preferred foods, and proper food prices. These results suggest that food court customers have interests that are distinct from restaurant customers and may need to be treated differently. It is anticipated that this data will be useful to the foodservice industry in order to segment customer characteristics by different dinning behaviors.
