In this paper we introduce the Internet-based purchase support systems using data mining and case-based reasoning (CBR). Internet Business activity that involves the end user is undergoing a significant revolution. The ability to track users browsing behavior has brought the vendor and end customer's closer than ever before. It is now possible for a vendor to personalize his product message for individual customers at massive scale. Most of former researchers, in this research arena, used data mining techniques to pursue the customer's future behavior and to improve the frequency of repurchase. The area of data mining can be defined as efficiently discovering association rules from large collections of data. However, the basic association rule-based data mining technique was not flexible. If there were no inference rules to track the customer's future behavior, association rule-based data mining systems may not present more information. To resolve this problem, we combined association rule-based data mining with CBR mechanism. CBR is used in reasoning for customer's preference searching and training through the cases. Data mining and CBR-based hybrid purchase support mechanism can reflect both association rule-based logical inference and case-based information reuse. A Web-log data gathered in the real-world Internet shopping mall is given to illustrate the quality of the proposed systems.

US Retailers consider two major holiday shopping days as their most profitable-the Friday after Thanksgiving, Black Friday, and the Monday after Thanksgiving, CyberMonday. Online shopping discount events have boosted up the shopping markets resulting in pumping up National economy. For such reasons, Korea also has launched online shopping discount event, which is called 'Cyber hot days'. The primary purpose of this paper is to understand consumer behavior on Cyber hot days and suggest how retailers can harness those consumer behaviors and how government agency can support both retailers and consumers to boost up shopping markets. The results of empirical test shows that economic value, emotional value, and product variety were found to be significantly related to consumers' attitude on Cyber hot days, but convenience value, social value, and product uniqueness were not. Consumers' attitude was also found to be significantly related to the repurchase intention. It implicates that price, enjoyment, and product variety are important aspects to Korean consumers when they purchase during online shopping discount event.

자사주 매입에 대한 선행연구는 대부분 그 분석기간이 10일 또는 20일에서 길어도 3개월을 초과하지 않는다. 그러나 투자자들의 공시에 대한 믿음의 수정은 이익발표 등과 같은 추가적인 정보가 나올 때에 이루어질 가능성이 더 크며 이러한 정보들이 자사주매입 공시 후 20여일 후에 나올 가능성은 더 크다고 할 수 있다. 외국의 선행연구에서도 공시후 주가추이분석은 $1{\sim}5$년을 측정기간으로 하고 있으며 동 기간동안에 추가적인 주가상승이 있음을 보고하고 있다. 본 연구에서는 기존의 연구와 달리 표본기간과 표본수를 확대하고 주가반응을 살피는 기간을 연장하여 자사주매입 공시의 정보효과에 대해 검증하였다. 검증 결과 기존의 연구나 실무계에서 주장하는 공시 후 20여일 동안의 주가상승은 자사주매입의 정보신호효과로 인한 것이라는 증거를 찾을 수 없으며, 주가의 상승 자체도 일반적인 현상이 아니라 특정한 연도(주가하락이 극심했던 1997년도)에 국한된 현상임을 확인하였다. 그러나 특정연도에 추가적인 주가상승이 발생한 이유에 대해서는 명확한 결론을 내 릴 수 없었다. 또한 자사주매입으로 인한 주가의 추가 상승은 단기적인 현상이 아니라 매우 장기적인 현상일 것이라는 점에 착안하여 분석기간을 공시 후 80여일로 늘려서 분석을 실시한 결과 정보신호효과와 관련된 변수가 유의적인 값을 가지기 시작하였다.

Trust is central to human relationships, at all times and places. The importance of trust is fundamental in all areas of human life, not only in the area of business administration. 2,500 years ago in China, Confucius taught that the foundation of politics was the trust of the people, more important even than military strength or the supply of food. Shakespeare's play, "Much Ado about Nothing' is about trust and deception. These days, trust and transparency in a commercial organization's business culture form the basis of the 'social capital' by which that organization increases its productivity. A successful company raises productivity by the accumulation of social capital, derived from a trust relationship between business partners, and between the company and consumers. Trust is the crucial factor. At the national level, building trust determines a nation's competitiveness. For a company, long term trust relationships with customers are essential for its survival in a business environment of rapid change. Such relationships, based on trust, are important assets to ensure a company's competitive advantage, and need to be organic to that company's business culture. Because of this importance, trust relationships have been studied in diverse areas within business administration, and especially within marketing, where they form the basis of a successful relationship between producer and consumer. However, what has been lacking is a unified definition of trust. Research has been conducted on the basis of various definitions and models. The majority of researchers have not considered the multidimensional character of the concept of trust until now. Approaches based on a one dimensional model have undermined the value of research results. Furthermore, researchers have only considered trust and trustworthiness as a single component. The majority of research has explored the consequences of perceived trust for outcomes such as loyalty or cooperation, but has neglected the effects of trustworthiness upon the mechanisms of consumer trust. This study focuses on the dimension of trust from such a perspective. It seeks to verify the effect of trust on customer intentions by breaking it down into three separate components: 1) the salesperson, 2) the product/service, and 3) the company. The purposes of this paper are as follows: Firstly, we review the multidimensional nature of trust objects: the salesperson, the product/service, and the company. Secondly, we analyze the relationship between multidimensional trust and trustworthiness. Thirdly, we analyze the connection between trust and repeat purchase intentions for the maintenance of long term relationships. For these purposes the author has developed several hypotheses as follows: H1-1: The competence of a salesperson is positively associated with the trust given by the consumer to the salesperson. H1-2: The benevolence of a salesperson is positively associated with the trust given by the consumer to the salesperson. H2-1: The competence of product/service is positively associated with the trust given by the consumer to the product/service. H2-2: The benevolence of product/service is positively associated with the trust given by the consumer to the product/service. H3-1: The reputation of a company is positively associated with the trust given by the consumer to the company. H3-2: The physical environment of a company is positively associated with the trust given by the consumer to the company. H4-1: Trust in a salesperson is positively associated with repeat purchase intentions. H4-2: Trust in a product/service is positively associated with repeat purchase intentions. H4-3: Trust in a company is positively associated with repeat purchase intentions. The data was compiled from 366 questionnaires. 500 questionnaires were collected, but some of the data was considered unsuitable and inappropriate. The subjects of the survey were male and female customers purchasing products at department stores in Seoul, Daegu and Gyeongbuk. It was carried out between Oct. 25 and 29, 2007. The data was analyzed by frequency analysis using SPSS 12.0 and structural equation modeling using LISREL 8.7. The result of the overall model analysis is as follows: Chi-Square=445.497, d.f.=185, p-value=0.0, GFI=.901, RMSEA=.0617, NNFI=.986, NFI=.981, CFI=.989, AGFI=.864, RMR=.0872. The results of the overall model analysis were coherent. It was found that trust is a multi-dimensional construct, that each of the dimensions of trust are meaningful influences on customer's repurchase intention. Trust in a company may be the most relevant, while trust in a product/service and a salesperson may be less relevant to repurchase intentions. The effective factors in determining trust in a salesperson and a company's product/service were found to be competence and benevolence. Factors in determining trust in a company were its reputation and physical environment, and the relationship of each effective trust factor has been verified in this research. As a result, it was found that competence and benevolence have a meaningful influence on trust in a salesperson and in product/service. It was also found that a company's reputation influences the overall trust in the company significantly but a company's physical environment does not have much effect.

The purpose of this study is to analyze products for good taste and convenience, which become an engine to constantly create customers. In addition, this study is aimed at investigating the relationship between the selective attributes of Home Meal Replacement, the perceived utilitarian value, and the repurchase intention, and drawing new suggestions on the Home Meal Replacement market from a new marketing perspective. Based on a total of 215 samples, this study reviewed the reliability and fitness of the research model and verified a total of 5 hypothesized using the Amos program. The result of study modeling was GFI=0.905, AGFI=0.849, NFI=0.889, CFI=0.945, and RMR=0.0.092 at the level of $x^2$=230.22 (df=126, p<0.001). First, the food quality (${\beta}$=0.221), convenience (${\beta}$=0.334), packing (${\beta}$=0.278), and employee service (${\beta}$=0.204) of home meal replacement consideration attributes had a positive (+) influence on perceived utilitarian value. Second, perceived utilitarian value (${\beta}$=0.584) had a positive (+) influence on repurchase intention. The factors to differentiate one company from other competitors in terms of the utilitarian value are the quality of food, convenience, wrapping, and services by employees. This study has illustrated the need to focus on the development of a premium menu to compete with other companies and to continue to research and develop nutritious foods that are easy to cook. Moreover, the key factors to have a distinct and constant competitive edge over other companies are the alleviation of consumer anxiety over wrapping container materials, the development of more designs, and the accumulation of service know-how. Therefore, it is necessary for a company to strongly develop the key factors based on its resources as a core capability.

This study investigates the wearing conditions and satisfaction level of middle school boys' uniforms. The subjects for the survey were 626 male students from 9 middle schools in Seoul. Data were analyzed using the SPSS 14.0 program. The results of this study are as follows; 1) When purchasing school uniforms, students considered the comfort and the fit important. Student considered importantly the shoulder width of jacket, the shirt length and the sleeve length of shirt, and the pant length and the pant width of pants. 2) Most of students purchased one size bigger school uniforms because they need to wear school uniforms for three years. About 80% of students had difficulties in understanding the meaning of size label, and this made it difficult to select the right size of school uniforms even if they knew their body size exactly. 3) About 10% of students repurchased school uniforms because their school uniforms did not fit any more. The periods of repurchase were the 1st grade 2nd semester and the 2nd grade 1st semester. 4) The waist circumference of pants and the pant width were evaluated larger and the pant length was evaluated to be longer (36.6% of students evaluated that the pant length was longer). Compared to 2nd grade and 3rd grade, the freshman felt that school uniforms were bigger. 5) 44.9% of students had the experience of repairing their school uniforms. The most frequent reason for repair was that the size of school uniforms did not fit well. 202 students repaired the pant length and 86.1% of them reduced their pant length.

The purpose of this study is to examine the effects of brand identity of coffee specialty stores on customer 's brand trust of customers, brand attachment, revisit intention, and word of mouth intention. A survey was conducted and 342 copies were used in the analysis of the structural equation model. As a result of the study, the brand identity was proved to have a positive effect on brand trust. In addition, brand trust has a positive effect on brand attachment, indicating that it affects affection on the brand depending on the degree of trust on the brand. Brand attachment had a positive influence on revisit intention and positive influence on word of mouth intention. Therefore, the proper construction of brand identity is linked to the acquisition of fixed customers by linking with the intention of repurchase, and it affects the profit generation of brand, so the brand manager can confirm that proper establishment of brand identity and marketing strategy should be set up.

This study was conducted to determine recognition of Chikhanwoo, promote its market competitiveness, and vitalize its uses in Korea. This research was carried out on 465 people, including 264 of the general public and 191 livestock farmers. For awareness of Chikhanwoo, 53.6% of the general public and 86.9% of livestock farmers recognized Chikhanwoo (P<0.001) through TV, Internet, news, magazines, and others. For consumption behaviors of Chikhanwoo meat, 4.3% of the general public and 1.9% of livestock farmers have purchased Chikhanwoo meat in the past. Most of them hinted at their intention to repurchase and highly intimated their wish to purchase on whether Chikhanwoo tastes better, is more nutritious and is safer than Hanwoo. In addition, they thought country of origin and price were the most important factors for purchasing (P<0.001). For recognition of the Hanwoo grading system, they preferred $1^{{+}{+}}$ and $1^+$, significantly (P<0.001). For need for quality certification, most respondents thought that the government should introduce a quality certification system for Chikhanwoo. For importance factor of prevalence of Chikhanwoo meat, marketability value had the highest degree of importance, followed by taste, quality, tradition and cooking methods (P<0.001). Results of this study show that domestic consumption of Chikhanwoo can be boosted by supplying Chikhanwoo meat with a differentiated taste and a safety assurance to the general public. There is also need to enhance genetic resources and improve brand value of Chikhanwoo. Continuous research and efforts should be made for the development of the livestock market.
