Finding the factors to affect the success of the business web sites is critical to enhance their competitiveness. This paper categorizes these factors into 4 quality measures: system, information, service and entertainment. The success is measured via user's satisfaction and loyalty. It surveys 474 Internet users to explore the effect of the quality measures on web site success. We confirm the causal effect of quality factors on users' satisfaction and loyalty. Furthermore, a comparative study is performed for web site types, such as finance, e-commerce(shopping mall), and entertainment. We note that the effect differs in web site types.

Due to the explosion of e-commerce, recommender systems are rapidly becoming a core tool to accelerate cross-selling and strengthen customer loyalty. There are two prevalent approaches for building recommender systems - content-based recommending and collaborative filtering. Collaborative filtering recommender systems have been very successful in both information filtering domains and e-commerce domains, and many researchers have presented variations of collaborative filtering to increase its performance. However, the current research on recommendation has paid little attention to the use of time related data in the recommendation process. Up to now there has not been any study on collaborative filtering to reflect changes in user interest. This paper proposes dynamic fuzzy clustering algorithm and apply it to collaborative filtering algorithm for dynamic recommendations. The proposed methodology detects changes in customer behavior using the customer data at different periods of time and improves the performance of recommendations using information on changes. The results of the evaluation experiment show the proposed model's improvement in making recommendations.

This study analyses the relationship with the feature of the web usability and Social commerce. Therefore, this research tries to investigate the relationship about in which the characteristic of the web-site usability is connected through the confidence about the Social commerce site to the re-purchase. The existing research that the information system and Electronic commerce relates is considered and the usability factor about the Social commerce site tries to be drawn and these try to verify on the relationship with the trust building of the user about the Social commerce site and purchasing intention through the positive research. The result is follows. First, the visual property of the Social commerce site was confirmed to have the descriptive ability noted to the confidence. Second, it was confirmed to have the descriptive ability that information characteristic about the Social commerce site notes to the confidence. Third, it was confirmed to have the descriptive ability that relative characteristic about the Social commerce site notes to the confidence. The importance of the web-site usuability has preferentially to be considered in being put through this research and building the confidence of the social commerce user could be known. When running with the social commerce site design, this is determined because it can become the useful standard.

With the development of e-commerce and information access, recommender systems have become a popular technique to prune large information spaces so that users are directed toward those items that best meet their needs and preferences. In this paper, clustering technique is applied in the collaborative recommender framework to consider semantic contents available from the user profiles. We also suggest methods to construct user profiles from rating information and attributes of items to accommodate user preferences. Further, we show that the correct application of the semantic content information obtained from user profiles does enhance the effectiveness of collaborative recommendation.

Trade Portal Site(TPS) is one of the innovative skills which makes it possible for small and medium-sized enterprises(SMEs) to manage international trade activities more efficiently by using the newest information and telecommunication technology. Based on performance and an existing research related to using information technology, this research analyzed the user's degree of utilization of TPSs which moderates effects between SMEs characteristics and export performance of SMEs. According to the results of the empirical study on actual data of 194 sample firms by using moderated regression analysis, there are significant only organizational characteristics among determinants(such as organizational characteristics, export characteristics) as the degree of utilization of TPSs. These research results provide many useful insights to the CEOs of SMEs using the services of TPSs, e-Trade system developers, and government policy makers. First, CEOs and managers of SMEs should have thorough understanding of the importance of the new information technology and e-Trade and positively adopt new e-Trade solutions and systems to their export processes to enhance global competitiveness. Second, TPS managers and e-Trade systems developers must concentrate on improving the user's degree of utilization of TPSs. Finally, the government agency should develop the various e-Trade promotion policies to support the efforts of SMEs organizational characteristics and TPS to increase the degree of utilization of TPS, which have positive effects on the export performance of SMEs.

We can buy products everywhere from Web-based shopping mall using desktop, cellular phone or PDA. To guarantee the various services for different equipment, shopping mail systems should allow a lot of different size or quality of images to provide a good service to their customers. Despite of same product image, each shopping mall saves the image in its storage space individually. Furthermore, all the product images in each shopping mall are stored as images of different quality. It may waste resources of shopping mail server and bring us developmental overhead. It is difficult to update all the images for product that is used by distributed e-catalog in everywhere. In this paper, we extended the proposed Web Image Server (WIS) for sharing one image with all clients and processing Image dynamically, so that we strengthened the function of managing shopping mall as a client of WIS and added the function of recording clients'log file and image catalog for shopping mall. We measured the response time from WIS and conventional e-Commerce site using by WAS which is one of the stress test tools for Web application. Furthermore, we measured WIS responses image requests in reasonable time when the current user is increased.

Together with the activation of wireless Internet, the interest for various integrated methods of the existing wired and wireless e-commerces is on the rise. For the integrated wired and wireless e-commerce, firstly, the optimized security and authentication under the radio communication environment should be decided. And also the user-friendly usage is important. In this paper, we designed and implemented wired and wireless interworking Mobile Wallet on terminal that can be used through both wired and wireless methods by developing electronic wallet module for electronic payment using MIDP (Mobile Information Device Profile) based on J2ME (Java 2 Micro Edition). The characteristics of mobile wallet implemented in this paper provide the stability through encoding/decoding payment information and on-line usage on wired/wireless environments through downloading electronic wallet. In addition, we also present safe and convenient payment method for e-commerce based on wired/wireless Internet.
