With the remarkable progression of network and the sophistication of contents, we now see various ways of communication methods in World Wide Web. In such trend, 3D web deserves our attention, which is applied for various areas such as education, game, chatting, e-commerce. Among those, by using 3D contents, e-commerce, especially the customized e-commerce, can give users more rich information about products. However, most of current 3D e-commerce sites are adopting a mere tool-based methods without considering contents and interaction required for the customized e-commerce. So, this paper proposes the direction of developing 3D interaction program for the customized e-commerce, based on a study on the required information elements about products and the interaction of controlling those factors. The evaluation to compare with the existing program is follows by the development of practical program, to give more persuasive reasons on the advantages of 3D e-commerce program.

Objective: The aim of this study is to show a correct application procedure using the compact Korean anthropometric data application program called Korean Human Scale(KHS) for anthropometric design. Background: The nation-wide anthropometric survey project called 'Size Korea' developed KHS and distributed it to the public on the web site. But some insufficiency of the current web service of KHS misleads the users; they just put their own statue and pick up a meaningless data for a body dimension. Method: This study provides five steps to follow to read appropriate data from KHS for an anthropometric design. Results: As a case study, the depth dimension of the supervisory and control console used in the Korea nuclear power plant was determined following the procedure and compared with the console design guideline recommendation. Conclusion: The supplementary anthropometry table should be added on the web service of KHS for users to read a meaningful data for design. Application: If properly used, the KHS has a lot more potential application area than users can expect such as in control center design area.

In this paper, a example of a development of web-based remote monitoring and control system using Java technology on TCP/IP is proposed. We implemented Client/Server socket programs using Java Socket class, and applied those to a greenhouse made from LEGO blocks and made web-based greenhouse remote monitoring and control system. Implemented System transferred states of greenhouse to client programs, and control signals from client program were transferred to Server. Greenhouse model was controlled well by the system.

In this paper, we have designed and implemented Web-based realtime distant education system by using multimedia CAI and Java technology. The proposed system can provide not only Web-based courseware but also text-based text lecture and distant OHP in real time. The Courseware provides computer basic education and has been developed by using Authorware. The Client/server program of Text lecture and distant OHP for a realtime distant education has been developed by using Java applet and application. Java servlet has been used to construct CGI programs.

To develop a business system of enterprise, there are so many problems such as increasing development time, cost, expanding network traffic, extension cost of network, and efficiency deterioration. In this paper, we propose the web application development tool based on XForms that is standard that can come up with solution problems of existing web program. This tool applied concept and specification of XForms to development environment. And it can efficiently implement X-internet.

ZigBee technology that is observed to radio network of low electric power with latest WPAN's IEEE 802.15 .4 technologies is evaluated as best technology for sensor network and digital home network construction. This need exclusive use application for monitoring, managing, controlling and organizing this nodes. However, these program has weaknesses that is hard to construct flexible system with Internet. This paper will use web server linked with gateway to manage sensor network that is consisted of ZigBee node and design system that manages ZigBee device with relative fast responsibility using AJAX web technology.

In this paper, web based monitoring systems are implemented for multi-axis force control systems of an intelligence robot. A web based monitoring system is implemented by porting Linux at embedded systems which include a Xscale processor. A device driver is developed to receive data from multi-axis force sensors in Linux operation systems. To control this device driver, a socket program for the Labview is also developed.

Cosim (Hardware and Software Co-Simulator) is a JavaBeans-based simulation tool fur validating systems architecture and estimating performance of web applications. Cosim has four components: Modeler, Translator, Engine and Scenario. Users start from Modeler to describe systems architecture in UML(Unified Modeling Language) deployment diagram, and then specify hardware & software performance parameters such as execution delay, network topology, and frame size. All information specified on Modeler are sent to Translator, and then automatically converted to Java programs. Scenario is responsible to run the Java program and produce results in text reports and graphs. Developers can reduce development time and cost by validating systems architecture of web applications before the actual deployment.

In this study, 63 university seniors majoring Child Studies were in an 8-week Web Based Instruction (WBI) program. Student characteristics of learning motivation, self-regulatory learning strategy, and learning style (Kolb, 1985) were the independent variables. Learning effects as dependent variables were measured by paper test and work assessment. Spearman's $\rho$ was calculated and tests of rank order difference were used for the data analysis. Results showed that learning motivation and self-regulatory learning strategy had meaningful positive relations with learning effects on the paper test score. Learning effects showed differences by learning style. These findings indicated that the learner's characteristics should be considered in the design and development of more effective WBI environments.

An upper bound elemental technique (UBET) program has been developed to analyze forging load, die-cavity filling and effective strain distribution for flash and flashless forgings. The simulation for flash and flashless forgings are applied axisy mmetric and plane-strain closed-die forging with rib-web type cavity. Inverse triangular and inverse trapezoidal elements are used to analyze flashless forging. The analysis is described for merit of flashless precision forging. Experiments have been carried out with pure plasticine billets at room temperature. Theoretical predictions of the forging load and the flow pattern are in good agreement with experimental results.
