Web navigation mining is a method of discovering Web navigation patterns by analyzing the Web access log data. However, it is admitted that the log data contains noisy information that leads to the incorrect recognition of user navigation path on the Web's hyperlink structure. As a result, previous Web navigation mining systems that exploited solely the log data have not shown good performance in discovering correct Web navigation patterns efficiently, mainly due to the complex pre-processing procedure. To resolve this problem, this paper proposes a technique of amalgamating the Web's hyperlink structure information with the Web access log data to discover navigation patterns correctly and efficiently. Our implemented Web navigation mining system called SPMiner produces a WebTree from the hyperlink structure of a Web site that is used trl eliminate the possible noises in the Web log data caused by the user's abnormal navigational activities. SPMiner remarkably reduces the pre-processing overhead by using the structure of the Web, and as a result, it could analyze the user's search patterns efficiently.

Evaluating a project is one of the key activities in managing projects, and thus it should be implemented as a part of the entire project management system. However, currently deployed systems suffer from deficiencies such as the lack of supporting distributed environment and integrity problems. Web service technology, which enables applications to work inter-operatively under a distributed computing environment, is said to solve such problems. In this paper, the web service technology is applied to evaluation management systems. The process of evaluation is designed based on the web service, data is modeled and a pilot system is implemented to test the feasibility of the technology to the domain of project evaluation.

The main topic of this paper is how to structure information so that the view of the web, both within and across web pages, is dynamically customizable. We present an architecture that integrates Object-Oriented Databases with the World Wide Web to organize such dynamic structures. Different non, or the same user at different times, could have different views of the web. We discuss several architectural variants and implementation issues. Our chosen architecture provides high flexibility for a wide variety of applications, ranging from software development environments to the IO-web system.

To support business services interoperation, the BSD (Business Service Document), which is an extension of the Web Service Description Language (WSDL) the web service specification of the World Wide Web Consortium (W3C) was designed. The WSDL presents comprehensive standards for the interoperability of software components and W3C delegates extensions of WSDL to the users for their own purposes and objectives. In this article, BSD Creator, which can generate well-formed and valid BSDs, was designed and implemented. Also, the BSD Operation Pilot System where service providers can publish BSD specification documents and service users can search for services, was implemented and presented. BSD Creator and the BSD Operation Pilot System, which are the outcomes of this study, were assessed for their quality and usefulness using ISO/IEC 9126. The outcomes of this paper will be the basis on which industry groups can construct a Business Services Interoperation System, and are expected to contribute to the revitalization of business service interoperation.

In this paper, we suggested a model that reflects the role played by the consumer's regulatory focus (promotion focus and prevention focus) as determinant factors of trust in the Web site. Also, we considered the moderating effects of consumers' purchasing experience toward online shopping. We conducted a two-month survey of 230 individuals using online shopping sites for hypotheses testing. The study results are summarized as follows. Firstly, promotion focused consumers showed higher trust to a web site compared to prevention focused consumers. Secondly, the moderating effect of purchasing experience between regulatory focus and consumer trust to a web site is statistically significant. The effect of a prevention focused consumers on consumer trust to a web site is stronger when purchasing experience toward online shopping is high compared to low. Based on these findings, this study presents practical and academic implications of the research.

Recently, RFID(Radio Frequency IDentification) has emerged as the main technology in the logistic services. When the existing recognition technology based on bar codes brings about lots of problem due its own limits. RFID becomes the center of attention to solve them. However, RFID is not without any obstacles : companies have their own operating systems. while RFID is developed regardless of each campany's special features. RFID middleware system based on web service is expected to remove these obstacles. This paper shows how to operate the middleware based on web service and to lay in the DB the tag informations taken from reader system Middle assures that companies adopting RFID system for their logistic service are given athptabwebty to any systems whatsoever, avaweable by way of defining logistic information, tag information and reader information. For this purse, we implement as the basic web service a middleware system that turns all data into XML(eXtensatle Markupmsngunfo) of SOAP(Simple Object Access Protocol), the standard data.

In this paper, we design and implement a distributed web-storage and a group office system based on the distributed web-storage. It is easier to customize the proposed group office according to user's demands than existing web-based applications. Our proposed web-storage is distributed system which consists of multiple storage servers. The web-storage provides storage with considering the user's location so as to provide fast storage service.

Quantum chemistry has many concepts that are either abstract or counterintuitive, giving students difficulties in understanding them. Fortunately, the advancement of web technologies provides us with hordes of powerful tools to produce rich multimedia web applications that supplement traditional classroom teaching. In this paper we present an approach to address this issue that combines interactive simulations and visualization on the web browser using Shockwave technology. With several examples, we show how to take advantage of the features of the Shockwave technology in developing web-based course material with ease.
