The prototype of forest fire management system on Web was studied. In the architecture of this system, one of the most important concerns is to handle load upcoming to Web Server so that it provides Web service without any delay or failure. In order to solve this problem, the agent is designed on dispatcher in a Web server cluster and implemented to distribute load dynamically by considering the information related to load coming to the Web Server such as the number of connection to the Map Server. The proposed forest fire management system has user-friendly interface with the GIS mapping functionality by selecting Map Objects Internet Map Server (MO IMS) as Map Server and is implemented using Java as programming language.

Web GIS (Geographic Information Systems) service systems provide the various GIS services of analyzing and displaying the spatial data with friendly user-interface. These services are expanding the business domain and many users want to access the distributed various spatial data. But, it is difficult to access diverse data sources because of different spatial data format and data access methods. In this paper, we design and implement web GIS services based on the inter-operability and GML (Geography Markup Language) of OGC(Open GIS Consortium) in web distributed environment. Inter-operability provides unique accessing method to distributed data sources based on OLE DB technology of Microsoft. In addition, GML support web GIS services based on XML. We design these GIS services as components using UML (Unified Modeling Language) of an object-oriented modeling language for specifying, visualizing, constructing, and documenting the artifacts of software system. In addition, they also were developed in object-oriented computing environment, and it provides the interoperability, language-independent, easy developing environment as well as re-usability.

Information system outsourcing induces firms to concentrate on the core competence and to improve business value by utilizing specialized information systems outsourcing vendors. However, for those strategic effects, the outsourced information systems should guarantee a certain service level. Now companies are considering to adopt SLA(Service Level Agreement) as a method to check the service level of the outsourced information systems in quantitative terms. On the contrary, customer satisfaction survey supports qualitative analysis, and helps companies to understand the qualitative effects on information system more systematically. Recently, the growing use of the internet makes customer satisfaction survey to be carried out on the web. For that reason, lots of researches related to web survey have been performed. But these researches are just focused on finding out only items to be measured and the effect of web survey. In this paper, based on the service quality research model for information system outsourcing, we formalize and propose a web survey process, a system architecture, and a functional structure for information system outsourcing customer satisfaction survey. Additionally, we provide the implementation results for the web survey systems.

The interest of data mining in artificial intelligence with fuzzy logic has been increased. Data mining is a process of extracting desirable knowledge and interesting pattern ken large data set. Because of expansion of WWW, web data is more and more huge. Besides mining web contents and web structures, another important task for web mining is web usage mining which mines web log data to discover user access pattern. The goal of web usage mining in this paper is to find interesting user pattern in the web with user feedback. It is very important to find user's characteristic fer e-business environment. In Customer Relationship Management, recommending product and sending e-mail to user by extracted users characteristics are needed. Using our method, we extract user profile from the result of web usage mining. In this research, we concentrate on finding association rules and verify validity of them. The proposed procedure can integrate fuzzy set concept and association rule. Fuzzy association rule uses given server log file and performs several preprocessing tasks. Extracted transaction files are used to find rules by fuzzy web usage mining. To verify the validity of user's feedback, the web log data from our laboratory web server.

This study proposes a web presence readiness model based on pre-payment service functions and a post-payment service function both of which embrace the major concerns of customers in the online purchasing context. Based on the concept of customer utility from the product itself and instrumental utility, the research model suggests four antecedents including, Perceived Economic Benefits, Product Search Support Quality, e-Shopping Method Diversity, and Post-Payment Support Quality. We empirically examined a proposed research model using data collected from online rating company websites. Among the four antecedents, post payment support quality is found to be the most influential determinant of customer evaluation on e-commerce websites. Based on the empirical results, the current study proposes an alternate model of web presence readiness. The findings of this study may provide an insight to field practitioners designing commercial websites. The implications and future research directions are further discussed.

웹 서비스의 활용 범위가 커지고 실제적인 구현사례가 늘어감에 따라, 웹 서비스 품질모델을 현실적으로 적용할 수 있는 방법에 대한 중요성이 커지고 있다. 웹 서비스 품질을 일관성있게 유지하기 위해서는 웹 서비스 품질보증에 대한 방안이 연구되어야만 한다. 웹 서비스 보증이란 웹 서비스의 품질수준을 일정수준이상으로 유지하기 위한 행위들의 총체를 의미하며, 이를 위해 웹 서비스 품질보증자란 새로운 개념의 관계자가 국제기구에서 웹 서비스 표준으로 새롭게 제시되었다. 웹 서비스 품질보증자는 웹 서비스 사용자들의 품질요구사항을 수렴하여, 웹 서비스 제공자가 일정 품질수준이상의 웹 서비스를 제공할 수 있도록 감시한다. 웹 서비스 제공자와 사용자 그리고, 품질보증자는 웹 서비스 수준을 관리하기 위해 서비스 수준을 측정하여 그 결과에 따라 페널티와 인센티브를 부여하는 SLA(Service Level Agreement) 방식을 적용할 수 있다. 하지만, SLA에서는 서비스 사용자와 제공자가 같은 서비스 항목에 대해 일대일로 대응한다는 전제를 가지고 있어서, 다수사용자와 공공성, 그리고 제3자 관리와 같은 웹 서비스 프레임워크에는 적합하지 않은 점들이 존재한다. 따라서, 웹 서비스에 SLA를 적용하기 위해서는 웹 서비스의 이러한 특성들을 반영한 새로운 보증기법이 필요하다. 본 논문에서는 품질 기대수준을 표현하기 위해 웹 서비스 품질 위탁보증수준이라는 새로운 개념을 제시하고자 한다. 이는 각 사용자의 각 품질항목별 품질기대수준의 최대치라 할 수 있으며, 웹 서비스 품질관계자에게 일관성있는 품질 뷰를 제공한다. 본 논문에서는 이를 이용해 각 품질관계자가 보다 쉽게 일정 수준이상의 품질수준을 유지할 수 있는 방안에 대해 제시하고자 한다.

Today many owners of Web sites are looking to user's satisfaction survey as a key means of measuring the usability of a Web site. While it is preferred for it simplicity and ease of use, this survey method is not without potential risks. This paper focuses on showing that the existing practice of questionnaire-based usability measurement is subject to human recall errors, and that such flaws can be reduced when the questionnaire survey is followed by the users hands-on experience of the site. An empirical study was conducted, and the results indicate that the above speculation holds true. Even if respondents felt highly confident about their responses on a recall survey, a hands-on experience with a focal Web site increased the extent to which the respondents were satisfied with the shopping mall site. This indicates that a user's perception of the quality of a Web site may be distorted or lost as time goes by. In addition, the findings have shown that the use of the verbal protocol analysis method can reveal critical information that can help track the root causes of Web site usability problems, thereby helping to develop site enhancement strategies. The paper concludes with directions for future research.
