An understanding of performance of database driven network applications is critical in combating slow performance of e-commerce web sites, besides efficient web page design, and high quality and well-maintained web server equipment. This paper describes a method of measuring performance from the user viewpoint, which can help enormously in making realistic assessment of true performance of database driven applications. The performance measurements were taken at user locations by using several specially designed JavaScript functions along with ASP scripts. A performance study is presented in this paper, comparing performance of data access using stored procedures with the traditional way of querying a database. It is generally believed that stored procedures have performance benefits as they are pre-compiled. However, our study shows that the data access approach using stored procedures provides significant benefits(by about 30%) over the traditional approach for querying a commercial MySQL database, only when retrieving a substantial amount of data(at least 10,000 rows of data).

This paper examines the major determinants affecting the user satisfaction on e-Trade portal sites in small and medium-sized exporters. The development of our research model is based on the empirical studies on the service quality of information system, web sites or Internet shopping mall, and on the factors influencing the user satisfaction. With the help of a regression analysis and factor analysis, five hypotheses are derived and tested. The results from regression analysis suggest that the user satisfaction of e-Trade portal sites is affected by information characteristics and ease of use of e-Trade portal sites. In addition, the user satisfaction of e-Trade portal sites is enhanced by support for international trade. Our findings will be useful, especially for those who are planning to build user-oriented e-Trade portal sites.

In this paper, we present an experiment conducted to examine how the web site's architecture, content quantity and the user task complexity affect its usability. The experiment was performed in two phases on college students to visit existing web sites which are readily accessible via the Internet. The results of experiment show that the web site's architecture significantly affects the efficiency and the effectiveness interactively with its content quantity and the user task's complexity. On the other hand, none of the above three factors show significant effects on the satisfaction and the learnability. In particular, the web site's content quantity does not have any statistically significant effects on the satisfaction and the learnability. It implies that the factors affecting the satisfaction and the learnability are different from those affecting the efficiency and the effectiveness. The analysis reassures that it is essential to consider the context of use in designing a web site.

최근 들어 인터넷이 광범위하게 보급되고 무선 이동통신 기술이 눈부시게 발전하면서 무선 단말기를 통한 인터넷 상에서의 정보 검색이 시간과 장소에 구애받지 않고 가능하게 되었다. 하지만 무선 단말기를 통한 인터넷의 접근은 단말기 자체의 제한과 무선망의 제한으로 인해 기존 데스크 탑 컴퓨터의 유선 상에서 보다 웹 페이지 탐색에 많은 어려움을 가진다. 본 논문은 이러한 제약을 완화시키기 위해서 웹 페이지로부터 페이지 정보를 축소한 페이지 맵을 생성하여 웹 정보를 쉽게 검색할 수 있게 하는 페이지 재구성 시스템을 제안한다. 그리고 대표적인 웹 사이트에 대한 실험을 통해 제안한 시스템이 무선 단말기 상에서 빠른 웹 페이지 로딩 속도를 보장하며, 작은 스크린을 통해서도 효율적인 웹 탐색이 가능함을 보인다.

Providers for the commercial web sites are seriously competing for attraction and retention of customers. However, customer loyalty in the on-line business could be determined by factors different from those in the off-line business. In this paper, determinants for the customer loyalty in the on-line business are analyzed as two parts. The first part includes determinants that foster voluntary customer loyalty, such as satisfaction, self-involvement, and positive characteristics of Internet. The second part includes determinants that foster involuntary customer loyalty, such as switching barrier and bonds. Through the empirical study of 399 survey of Korean Internet users, both voluntary and involuntary factors contributing to the customer loyalty were found. Also, relationship between the positive characteristics of Internet and customer loyalty were found. The understanding of the determinants of customer loyalty will be an important information developing a winning strategy in the on-line business.

A specialized web search engine is an internet tool for detecting information in finite cyber world. It helps to retrieve necessary information in internet sites quickly In this paper, we design and implement a prototype search engine using method of mining for the association rule discovery. It consists of a search engine part and a search robot part. The search engine uses keyword method and is considered as various user oriented interface. The search robot fetches information related to ship parts n world wide web. The experiments show that our search engine(AISE) is superior to other search engines in collecting necessary informations.

Most of hospitals, especially small-scale hospitals, have tried to get customers through the Internet as what companies have done recently. There are various attempts that increase visits to one's web-site in plastic surgery hospitals. However, in plastic surgery, there have been few studies on which an attribute contributes to increase the number of web-site visit. In order to derive the important attributes on the number of visit, we compared functional attributes of 30 high-visit plastic surgery web-sites with those of 30 low-visit web-sites using statistical and data mining methods. For analysis, three methods have conducted including Multiple Discriminant Analysis (statistical method), Decision Trees (data mining method), and Artificial Neural Network (data mining method). Furthermore, results of each method have been evaluated one another. The result of this study shows that a few attributes like 'Simulating cyber plastic surgery program', 'recommendation of information' explain the number of the visitors between high and low visit web-site. The methodology employed in this study provides an efficient way of improving satisfaction of visitors of plastic surgery website.
