The purpose of this study was to examine the difference in nutritional knowledge and food preferences according to food-related lifestyle among 400 married women. Using the K-average clustering method, food-related lifestyles of subjects were categorized into three clusters: rational and diversity-oriented group, convenience-oriented group, and health-oriented group. The nutritional knowledge level and food preferences among three clusters were compared to each other using ANOVA test. The findings were summarized as follows: For the nutritional knowledge level, health-oriented group showed the highest mean score, whereas the lowest score was detected in the convenience-oriented group. The convenience-oriented group showed higher preferences for fish, meat, eggs, fruits, milk/dairy products, seaweed, grains, etc. among natural food than the other groups. Meanwhile, the rational and diversity-oriented group preferred legumes, and green vegetables, whereas the health-oriented group showed preferences for other vegetables. However, the convenience-oriented group reported more preferences for breads, noodles, pancakes, fried/stir-fried food, and processed food such as sausage, ham, and fast food, This study found that nutritional knowledge level and food preferences were significantly different according to food-related lifestyles of married women living in Seoul and Gyonggie areas.

Collaborative filtering systems have problems involving sparsity and the provision of recommendations by making correlations between only two users' preferences. These systems recommend items based only on the preferences without taking in to account the contents of the items. As a result, the accuracy of recommendations depends on the data from user-rated items. When users rate items, it can be expected that not all users ran do so earnestly. This brings down the accuracy of recommendations. This paper proposes a collaborative recommendation method for extracting typical group preferences using user-item matrix optimization and user profiles in collaborative tittering systems. The method excludes unproven users by using entropy based on data from user-rated items and groups users into clusters after generating user profiles, and then extracts typical group preferences. The proposed method generates collaborative user profiles by using association word mining to reflect contents as well as preferences of items and groups users into clusters based on the profiles by using the vector space model and the K-means algorithm. To compensate for the shortcoming of providing recommendations using correlations between only two user preferences, the proposed method extracts typical preferences of groups using the entropy theory The typical preferences are extracted by combining user entropies with item preferences. The recommender system using typical group preferences solves the problem caused by recommendations based on preferences rated incorrectly by users and reduces time for retrieving the most similar users in groups.

The purpose of this study was to investigate the effects of preschool children's taste preferences on their intake of nutrients and the degree of dental caries. The subjects were 126 preschool children (boys 62 and girls 64) in Daegu area. Their taste preferences and food intake were investigated and their teeth were also examined. The energy intake of boys (1550 kcal) were significantly higher than that of girls (1441 kcal). Daily dietary intakes of nutrients-except niacin and vitamin C-were higher than those of RDA. Vitamin B$_1$ intake of the group preferring a salty taste was significantly lower than that of the other group (p<0.05). Vitamin B$_2$ intake of the group preferring a salty taste was significantly higher than that of the other group (p<0.05). Vitamin C intake of the group preferring a hot taste was significantly higher than that of the other group (p<0.05). The group with a preference for sweet had more experiences of dental caries and more decayed teeth than the other group, but which is not significant. The experiences of dental caries were negatively correlated with protein intake (p<0.01). The decayed teeth were negatively correlated with energy and protein intakes (p<0.01). Our data suggested that taste preferences are associated with vitamins intake and the degree of dental caries in preschool children. It means the sweet preference increased the experiences of the dental caries.

The purpose of this study was to conduct nutrition education using animations for the establishment of proper eating habits among elementary school students and to evaluate its effectiveness. The subjects of this study were two classes of fourth grade students in an elementary school located in Daegu-city. There were 29 students in each class. One class, the "nutrition-education" group, received nutrition education; the other class, the "no-education" group, did not receive the education. After completing the eight nutrition lessons, the effectiveness of the education was analyzed by measuring changes in the nutrition knowledge, eating habits and food preferences of the nutrition-education group vs. the no-education group. Before nutrition education, there was no significant difference between the two groups in terms of nutrition knowledge. However, after the nutrition education, the nutrition-education group's nutrition knowledge was significantly improved, compared to that of the no-education group (p < 0.001). Following education, the nutrition-education group's responses to the "eating habit" item, "I eat fruits every day," were significantly more positive, compared to the responses of the no-education group (p < 0.01). However, for the ten food groups listed as food preferences, except for fish and shellfish (p < 0.05), there was no significant difference in the responses of the two groups. Following the education, the nutrition-education group showed significantly increased preferences for 12 food items (red beans, mackerels, yellow corvinas, dried laver, kelps, radish, lettuce, pears, kiwi fruits, plums, grapes and sweet drinks made from fermented rice) out of 112 items, compared to the selected preferences of the no-education group. After education, 75.9% of the students in the nutrition-education group indicated changes in their eating habits, and 89.6% of them answered that the nutrition education helped them change their eating habits. The most helpful medium for changing their eating habits was animations (31.0%), followed by songs (20.7%) and lectures (17.2%). As a result of this study, after completing the nutrition education, students in the nutrition-education group showed significant changes in food preferences, and their level of nutrition knowledge was significantly increased. However, their eating habits did not actively change. Therefore, in order to establish proper eating habits, a longer period of consistent education is required, using various educational media and learning methods such as extracurricular activities and discretionary activity programs.
