E-business curriculum needs to be developed reflecting requirements of the industry which involve a close relation with a job performed in the field, and a professional knowledge and an expert skill. In this paper, we present a method based on a market-oriented approach for developing an I-business curriculum. For the purpose, we analyze the opinion data resulting from the surveyed opinions of respondents working for I-business companies and evaluate the importance of each course being involved in the curriculum with respect to the job classification (e.g., Web planner, Web master, Web programmer, Web marketer, Web designer, Web PD), and then, complete a flow diagram considering precedence and relative difficulty among the selected courses. The E-business curriculum developed by the proposed method is useful to provide guidelines for determining courses required toward a desired job and for making a partial amendment of the curriculum.

The purposes of this study is to investigate the factor structure of web-site characteristics and antecedents factors affected to trust, satisfaction and behavioral intention of web-site. Refined data were consisted of 4 internet shopping mall survey and estimated the perception to visiting web site. Statistical methods are adapted Frequency, Factor Analysis and CFA(Confirmatory Factor Analysis) of LISREL. 8 program. Research findings are as follows. The factors of web characteristics indicated to product information/buying procedure clarification, stability and function of system, usability of web site, security and protection of individual information, design, clarification of enterpriser information, various payment methods and customer service. In regression analysis, dependent variables were trust, satisfaction and behavioral intention. reputation of site were significantly effected variables. External variables consisted of the 4 characteristics of web-site and reputation and trust, satisfaction and behavioral intention were internal factor.

For Web System composed of a variety of hardware, software and network system, there is a wide difference in price, function and capacity. In addition, it is important to select the most suitable system when web system is constructed as the claim of high-quality web service from user has increased. Data of bench-marking is usually employed when the system is selected. Evaluation with the result of bench-marking, however, is not easy at web situation composed of a variety of systems. In this paper, first integrated bench-marking of hardware, software and network system metric were determined, and the plan to effectively compare and evaluate the result of bench-marking by using fuzzy set were offered.

For the development of automobile lighting components, various designers, developers and manufacturing personnel are involved, each group needing different software tools. In this Smartlite project, several software tools were developed far product development of the lighting components and then tested using two different user interfaces (UIs); the first was based on a commercial CAD system (SDRCI-DEAS) and the second was based on a web browser. The specific focus of this study was a comparison between the new web-based UIs, and the UIs on commercial CAD systems. The usability data have been collected from the users at Visteon and showed that the web-based UIs provided comparable functionality with the CAD-based UIs in terms of performance and usefulness. For the criteria of accessibility, the web-based tools out-performed the CAD-based tools.

We can offer suitable information to users analyzing the pattern of users. An association rule is one of data mining techniques which can discover the pattern. We use an association rule which considers the web page visiting time and we should the pattern analyse of users. The offered method puts the weights in Web page visiting time of the user and produces an association rule. Weight is web page visiting time unit divide to total of web page visiting time. We offer rather meaningful result the association rule by Apriori algorithm. This method that proposes in the paper offers rather meaningful result Apriori algorithm

In this study, the Web Camera System is implementation and simulated on two different architectures. In the one architecture, a Web-server and Camera-server are implemented on the same system, and the system transfers motion picture which compressed to JPEG file to users on the WWW(World Wide Web). In the other architecture, the Web-server and Camera-server are implemented on different systems, and the motion picture is transferred from the Camera-server to Web-server, and finally to users. In order to compare system performance between two architecture, data traffic is measured and simulated in the unit of byte per second and frame per second.

인터넷과 WWW 이용의 급속한 증가로 인하여 인터넷 지리정보시스템의 보급이 확산되었다. 따라서 국내외의 분산된 다양한 데이터에 대한 접근이 가능하게 되었다. 하지만 웹을 통해 제공되어지는 지리정보 데이터의 이질성 때문에 지리정보를 공유하기가 어렵다. 그러므로 발생하는 데이터 구축에 대한 중복투자를 제거하고 지리정보 데이터의 상호 운용성(Interoperability)을 위해 본 논문에서 OGC(OpenGIS Consortium)의 웹 매핑 표준 기술인 WMT(Web Mapping Testbed)의 OWS(OGC Web Service)에 기반 하여 Web 매핑 서버를 설계 및 구현하였다. 이는 인터넷상에서 데이터 공유 및 교환의 포맷인 XML 에 근간을 둔 GML 을 통해서 Web GIS환경에서의 상호운용성을 제공하고자 한다.

This paper propose the DoubleQ web server that classifies incoming requests according to whether the requested document is cached or not. Requests that demand a cached document is put into the Service Queue while other requests are added to the Defer Queue. The DoubleQ web server services requests that are in the Service Queue before it services requests in the Defer Queue. This strategy is used to reduce disk accesses that have been the predominant overhead of traditional web servers. Experimental results using synthetic data show that improvements in the average user response time and the throughput of the web server may be achieved.

The purpose of this study is to implement web-based quality cost management system to measure the performance of quality improvement activities in the business firms. Developed WQCMS(Web-based Q-Cost Management System) have ability to collect and analyze quality data generated from various different departments in the inside or outside of the enterprise without any limitations, if end-users are able to access wide area network. It provides the capability to integrate quality information from database and to generate various easy analysis reports to management's needs using built-in analysis tool modules with real-time. The proposed system was developed using Microsoft's .Net technology, ASP.NET and MS-SQL Server 2000. By web-enabling Q-cost management system, the effectiveness of the system management and utilization was realized by easiness of information integration and economical efficiency.

As big data are one of main issues in the recent days, the interests on their technologies are also increasing. Among several technological bases, this study focuses on data visualization and R based on open source. In general, the term of data visualization can be summarized as the web technologies for constructing, manipulating and displaying various types of graphic objects in the interactive mode. R is an operating environment or a language for statistical data analysis from basic to advanced level. In this study, a web application with these technological aspects and components is newly implemented and exemplified with data visualization for geo-based open data provided by public organizations or government agencies. This application model does not need users' data building or proprietary software installation. Futhermore it is designed for users in the geo-spatial application field with less experiences and little knowledges about R. The results of data visualization by this application can support decision making process of web users accessible to this service. It is expected that the more practical and various applications with R-based geo-statistical analysis functions and complex operations linked to big data contribute to expanding the scope and the range of the geo-spatial application.
