This study examined contents of interaction that played an important role in learners' accomplishment of educational goals at web-based educational system. The purpose of the study was to find out design strategies of web-based education website that could give learners more satisfactory interaction. The study firstly investigated concept and values of web-based education as well as interaction by literature study to analyze web-based educational design principles at actual web-based education websites from point of view of interaction and to examine what factors should be used and reinforced at existing teaching. The findings were as follow: Web-based education websites made use of interaction with 'each design factor', such as colors, texts and images, etc that were based on communication designs to give 'information' by systematic interaction more than by social interaction.

XML is suitable to integrate various forms of engineering design data since it possesses the characteristics of both documents and data. In this research a web-based design system has been developed, which integrates various gear design data in the form of XML. The system generates XML document containing gear design data and transforms gear design data in the relational database into XML document form automatically. The XML documents are transmitted to gear modeler agent through SOAP, and then the agent is automatically executed and generates CAD model files and VRML files. The designer can check the generated VRML model of gear immediately in the web service.

This study describes the XML -based digitalization of structural design sheets for exchange on the web. For this purpose the data model of the XML document that represents the structural design sheets for buildings, including mathematical expressions and graphics that cannot be easily exchanged on the web, is defined. Then, the prototype that facilitates the web-based exchange of the XML documents is developed and the feasibility of the results of this study is discussed.

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.

The design and development of a Web-based Workflow Management System (WfMS) is described in this paper. WfMSs are employed by many organizations to manage their business processes efficiently. The goal of this research is to provide an effective management of design processes in a distributed and heterogeneous environment-an environment in which workflow participants are geographically dispersed and use different computing platforms. We identify the requirements of WfMSs for the distributed and heterogeneous environment. We present an approach to applying the Web technology to was. The developed system is composed of three main modules: Worflow Engine, Web-based clients, and Process Designer. The workflow engine is implemented in pure Java for portability to heterogeneous platforms. furthermore, the client interfaces are all programmed using applets, and thus they can be readily accessed through the Internet/intranet. The Process Designer provides a build-time function of generating process specifications. Some important functions of the developed system are explained in this paper. A prototype system has been developed and applied to design processes. The system allows effective cooperation among designers who may be geographically separated.

Developing and managing Web applications are more complex than ever because of their growing functionalities, advancing Web technologies, increasing demands for integration with legacy applications, and changing content and structure. All these factors call for a more inclusive and comprehensive Web application design method. In response, we propose a context-based Web application design methodology that is based on several classification schemes including a Webpage classification, which is useful for identifying the information delivery mechanism and its relevant Web technology; a link classification, which reflects the semantics of various associations between pages; and a software component classification, which is helpful for pinpointing the roles of various components in the course of design. The proposed methodology also incorporates a unique Web application model comprised of a set of information clusters called compendia, each of which consists of a theme, its contextual pages, links, and components. This view is useful for modular design as well as for management of ever-changing content and structure of a Web application. The proposed methodology brings together all the three classification schemes and the Web application model to arrive at a set of both semantically cohesive and syntactically loose-coupled design artifacts.

A key factor far realizing the internet-based virtual manufacturing system(VMS) and virtual enter-prise(VE) is how to precisely and effectively represent the machine elements and mechanics. In this paper, we present methods to represent the numerically controlled machine tools in the internet environment. The method is composed of: 1) geometrical modeling of the machine tools, 2) kinematic modeling for the movements of the machine tools, and 3) representing the developed model in the internet infrastructure. Based on the models. a web-based virtual machine tools (WVMT) is developed, and it can be accessed at hrrp://wvmt.postech.ac.kr. The WVMT can be used for various purposes: 1) web-based virtual manufacturing system, 2) web-based CAM system, and 3) CNC educational tools for the vocational school through internet.

The purpose of this study is to design and implement web-based quality cost management system to measure the performance of quality improvement activities in the business firms. The designed web-based quality cost management system which is also known as WQCMS (Web-based Q-Cost Management System) utilized newly classified objective performance indicator items to measure quality related activities. Well-classified performance measurement Indicator item lists which are played key role in the system was researched and standardized according to size and business categories of enterprise. Its code standards are based from fundamental PAF Model. Developed WQCMS 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 Microsofi'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.

We have many difficult problems to efficient development and management of a Web-based education system because of the various requirements of various demanders. A Web-based education system consists of instructors and operation managers of system and learners. Those three factors are the most important e]ements of a Web-based education system and we must consider those elements for design and development. In constructivist approach. acquiring knowledge is made by experiences among each members or elements. So we can say that the constructivist elements of a Web-based education system is learners and instructors, operation managers. In this study, we design and implement a Web-based education system, based on the interactions of extended demanders of Web-based education system in constructivist approach and object oriented modeling. In this study we can improve portability and reduce cost because of platform independence from presented system. And in experiment, we compare and analyse two platform web-based education system a point of effectiveness, cost, convenience.
