This study is aimed at examining the status of seafoods intake and preference to actively use the seafoods with high nutritional values and preference. For this purpose, this study conducted a questionnaire survey. The demographic features of the respondents are as follows: male and female high school students were 50%, respectively; first graders were 33.3%, second graders were 35.0% and third graders are 31.7%; the primary dietary-care giver was mother in 80% of the respondents. The survey results on seafood intake at home showed that the most frequently responses to the question of the degree of liking seafood were 'on average' and 'like it', respectively in order. The reason for preferring seafood is 'because it tastes good' in 43.7% of the respondents. Both male and female respondents answered they like seafood for its good taste. With respect to the degree of preference for the seafood provided from the school meals, there were more students who like it than those who do not like it. The most frequent reason to ingest seafood in the school meals is because 'I want to eat it' followed by 'because parents push', 'because friends eat it', 'because health-related TV programs recommend it', respectively in order. The most preferred seafood in the school meals was fried shrimp and the most disliked one is the boiled warty sea squirt. The above results collectively suggest that the preference level for seafood is low and the most preferred one is fried seafood. It is suggested that the nutritionists need to actively develop menu for the students to ingest more various seafoods.

In this paper, we draw upon Task-Technology Fit theory to investigate the fit attributes which impacted on customer preference over three virtual shopping channels which included TV home shopping, Internet shopping, and broadband applications, i.e. IPTV. The fit attributes also reflected the product category contingency, which is classified based on the degree of quality assessing difficulty on the web, such as quasi-commodity, look and feel goods, and look and feel with variable quality goods. Using the collected survey data, we employed stepwise regression analysis to validate the fit attributes in the context of performing virtual shopping task via those three distinctive media technologies. Furthermore, through ANOVA test with Duncan statistics, we reported comparative intensity of the valid fit attributes across the product categories and distinct media technologies. The results validated four critical fit attributes and significant distinctions among product categories and three virtual shopping channels. The findings provide practical insights in distribution channel design exploiting digital convergence technologies.

To establish good dietary behavior for middle school students, this study was conducted to analyze the needs of nutrition education and eating attitudes of 373 middle school students(boys 171, girls 202) in Hwaseong city. Using questionnaires, results were gathered and analyzed. Dietary behavior, food group intake and the needs of nutrition education were scored by a five-point Likert scale. Chi-square and student t-test were done for significant gender difference. The correlation between the needs of nutrition education with dietary behavior and food group intake was obtained by Pearson's r. The dietary attitude of 'try to eat first' and 'eating fast' were higher score in boys than in girls(p<0.05). Most of the students thought they didn't have any nutritional problems(71.8%). Nutrition education was considered necessary(54.9%) for proper growth and development(53.0%) in middle school. But 45.1% of students did not suggest by the reasons of 'short time to change'(28.2%), 'more effective in home'(27.4%). The appropriate time of nutrition education was pre-school(28.2%) or elementary school(27.4%), once a week(boys 51%, girls 71.3%) in frequency(p<0.001), and the information acquired by TV/Radio(30.0%) and internet(26.6%). Students(46.0%) wanted to know about 'growth and nutrition'. They were to learn information on the 'healthy growth'(4.10) and 'adolescent nutrition'(4.03). The vegetables group consumption and the thought of dietary attitude 'try to modify bad eating habits' were correlated with almost all categories of desired nutrition education. Through these results, good eating habits would be attained by nutrition education. A nutrition education program would require an expert teacher for middle school students.

The interviews were tape-recorded and the contents of interviews were analysed by researchers. Most mothers and children liked meats. It was found that children usually disliked vegetables such as onions, carrots, and green onions. Mothers perceived that many factors affected their children's food preferences: mothers' and fathers' food preferences, food offering at meals. mothers' food intake during pregnancy, children's food intake during weaning period, heredity peer pressure, and advertisements on television. Mothers made efforts to improve childrens food intakes in many ways: change of cooking method, emphasizing function of nutrients and food for health, conciliation and enforcement, and comparison to other children. The most affecting belief for mothers in food selection was family members' food preference. Health, balance in nutrient intake degree of food processes food additives, chemicals, convenience, diversity, and economy were also important beliefs to select food. Convenience was especially the primary belief in choosing and preparing children's snacks. Mothers offered frozen dumplings and meat, instant noodles, tuna, and ham for snacks for convenience. These results showed that mothers understood many aspects affecting children's food preference tried to improve children s food intakes and had several beliefs in food selection.

The proliferation of the Internet and communication technologies and applications, besides the conventional retailers, has led to a new form of distribution channel, namely home sopping through the telephone, TV, catalog or the Internet. The conventional and new distribution channels have different transaction costs perceived by the consumers in the following perspectives: the accessibility to the product information, the traffic cost and the opportunity cost for the time to visit the store, the possibility of 'touch and feel' to test the quality of the product, the delivery time and the concern for the security for the personal information. Difference in the transaction costs between the distribution channels results in the different selling prices even for the same product. Moreover, distribution channels with different selling prices necessarily result in different business surpluses. In this paper, we study the multilateral bargaining strategy of a manufacturer who sells a product through multiple distribution channels with different transaction costs. We first derive the Nash equilibrium solutions for both simultaneous and sequential bargaining games. The numerical analyses for the Nash equilibrium solutions show that the optimal bargaining strategy of the manufacturer heavily depends not only on the degree of competition between the distribution channels but on the difference of the business surpluses of the distribution channels. First, it is shown that there can be four types of locally optimal bargaining strategies if we assume the market powers of the manufacturer over the distribution channels can be different. It is also shown that, among the four local optimal bargaining strategies, simultaneous bargaining with the distribution channels is the most preferred bargaining strategy for the manufacturer.
