Most of searching systems used by shopping-mall provide too much information for user requirements or fail to provide appropriate items reflecting customer's preference. This paper aims to design and implement the product searching systems based on customer preference which will enable efficient product selection in the internet shopping-mall. The proposed system consists of user/provider interface, searching and model agent, data management system, and model management system. Especially, we construct the searching pattern database to support fast search using association mining method.

Diet is closely related to an economic level, but few studies have reported on the relationship between the economic level and eating habits, especially in college students. Therefore, this study was conducted to clarify differences in eating habits with a focus on processed foods according to allowance level in college students. This study was a cross-sectional survey of 500 college students using a questionnaire. The questionnaire consisted of general characteristics, eating behaviors, purchase of processed foods, and preference and intake frequency of processed foods. All subjects were classified based on monthly allowance: less than \300,000 (n=149), \300,000~400,000 (n=177), and more than \400,000 (n=124). All survey results were comparatively analyzed among the spending money groups. As the level of spending money of the subjects increased, the rate of skipping meals, eating out, and unbalanced diet increased (P<0.05). The reason for consuming processed foods was because they are easy to prepare. The factor considered the most when buying processed foods was price. However, these results showed no significant difference according to level of spending money. As spending money increased preference for retort, convenience, canned, and bottled foods significantly increased. Intake frequency of dairy products was lower, and the frequency of processed foods was significantly higher with more spending money. This study found that a higher level of monthly allowance in college students, was associated with higher rate of skipping meals, eating out, and unbalanced diet, and the preference and intake frequency of processed foods were also high. These results suggest that spending money level in college students, as an economic indicator, is relevant to intake of processed foods.

본 연구의 목적은 한국의 인터넷 사용자데이터를 통해 인터넷 광고의 시각적 모습만이 아니라, 내용적 차이에 따른 사용자 선호도를 제품 관여도를 포함해 분석하고자 한 것이다. 인터넷을 활용한 실험연구에 의하면 이미지 위주의 인터넷 배너광고가 텍스트 위주의 광고에 비해 사용자 선호도가 높았으며 관여도 또한 광고의 선호도에 통계적으로 유의한 영향을 미치는 것으로 나타났다. 이미지 위주의 광고는 제품과 관련된 관여도의 여부와 관계없이 전반적으로 텍스트 위주의 광고에 비해 사용자들의 호감을 얻고 있었다. 또한 전반적으로 정보 지향적 인 광고보다는 경품위주의 광고의 효과가 높았다. 본 연구는 배너광고를 활용하는 마케팅 의사 결정에 있어서 배너광고와 광고의 시각적 형태 외에도 광고에 포함되는 내용, 소비자와 제품의 관여도 그리고 그 상호효과에 대해 철저한 사전 분석이 있어야 기대하는 마케팅 목표를 이루 수 있음을 시사하고 있다.

This study estimates the random utility function of fluid milk using 1,165 survey responses in Laos. It finds that both products' attributes and individual characteristics affect consumers' preference for the milk and the hypothetical brand of Laos-Korea has a potential compared to four real dairy products. Results also show that calories have a positive relationship with consumer's preference while the price and fat content have a negative one. The decision for choosing each brand is significantly affected by individual characteristics such as gender, age, whether or not respondents live with their children, the level of education, income, the frequency of purchasing milk per week, and the region where they live. The preference for five brands appears in the order of Foremost, Nabong, Thai-Danish, Meiji, and Lao-Korea, and probabilities of purchasing each brand at the mean level are 30.9%, 17.48%, 21.48%, 15.0% and 10.39%, respectively. Nabong that was Lao national milk brand still has a significant market power even though it was closed in 2008. The policies to promote milk industry by implementing its national milk brand again would be more effective if it focuses on the young generation, female consumers, families with children, quality of dairy products, and Vientiane capital areas.
