Even the short history of the Web system, the technology related to the Web system has been developed rapidly. Yet, the quality of the Web-based application software has not been improved that much. For this reason, the efficient method to develop the Web-based application software is needed. This paper describes the items necessary to develop the Web-based application software. On the basis of ISO/IEC 12207-Software Life Cycle Processes this paper mainly suggests the analysis and design stage of the Web-based model for developing software. Also, this paper describes the methods to define the process and the entity for applying contents to Web-based application software. With the web-based model suggested in this paper the Web-RoadMap Methodology of KCC Information & Communication, a system provider in Korea, has been applied to the public-domain projects. Through the application, Web-RoadMap Methodology has been proved to be an applicable model for analyzing and designing the systems based on the web environments.

This Paper Presents an Internet-based Java self-learning educational system which consists of a management system named Java Web Player (JWP) and creative multimedia contents fer Java language. The JWP Is a Java application program free from security problems by the Java Web Start technologies that supports an Integrated learning environment including three Important learning Procedures: Java concept learning Process, Programming practice process and assessment process. This JWP enables the learners to achieve efficient and Interesting self-learning since the learning process is designed to enhance the multimedia capabilities on the basis of various educational technologies. On-line voice presentation and its related texts together with moving images are synchronized for efficiently conveying creative contents to learners. Furthermore, a simple and useful compiler is included in the JWP fur providing user-friendly language practice environment enabling such as coding, editing, executing and debugging Java source files on the Web. The assessment process with various items helps the learners not only to increase their academic capability but also to appreciate their current degree of understanding. Finally, simple multiple choices are given suddenly to the learners while they are studying through the JWP and the test results are displayed on the message box. The proposed system can be used for an efficient tool for learning system on the Web.

We introduce about XBRL, eXtensible Business Reporting Language, which is widely accepted as the international standard language for business financial reporting. XBRL is a language for the electronic communication of business and financial data which is revolutionizing business reporting around the world. It provides major benefits in the preparation, analysis and communication of business information. It offers cost savings, greater efficiency and improved accuracy and reliability to all those involved in supplying or using financial data. XBRL is a kind of XML application based on the open Internet technologies. We propose a framework for enterprise information supply chain using XBRL Web services. A Web service is defined as a software system based on XML and designed to support interoperable machine-to-machine interaction over a network by the W3C. Web services are frequently just application programming interfaces (API) that can be accessed over a network, such as the internet and executed on a remote system hosting the requested services. An XBRL Web service-based enterprise information supply chain enables for companies to implement seamless information supply chains from businesses to financial institutions, to supervisory authorities, and to other stake holders for real time information access. And thereby it is expected to contribute to the increase in the value of companies due to the enhanced visibility and transparency of accounting and management.

In this paper, an example of implementation of a embedded system technology for web based monitoring and control system is presented. For it interfaces with target board as an embedded system was developed, which was applied to specific green room model and verified of its usefulness. We implemented client/server socket programs using Java classes, and web based green room monitoring and control system as an user interface using JavaApplet. The implemented system did send information of green room model to client programs well on TCP/IP and control signals from client to green room model well too.

The outer race of the constant velocity(CV) joint is an important load-supporting automotive part, which transmits torque between the transmission and the wheel. The outer race is difficult to forge, because its shape is very complex and the required dimensional tolerances are very stringent. Therefore, the internet based shape inspection system is developed in this study to provide quick and accurate data through the easy control from users. Proposed system uses mechanical displacement sensors to measure the shape of CV joint that has six inner ball grooves, and commercially available Lab-View program is used to process measured data into the dimensional shape. Developed program provides a simple user interface that enables users real-time access of data measured from industrial production lines. Furthermore, it can exchange measured data via the internet between users and forging system operators. A java applet helped the system connection via internet. A data, IP access, is transmitted to the packet by TCP/IP. Our proposed system has many advantages over current measuring systems including fast and efficient data processing by real-time control, and system flexibility.

In this paper, we propose a mutual Authentication module, using ECDSA(Elliptic Curve Digital Signature Algorithm) for web-Camera system. which. is based on three module. first is authentication module which is based on ECDSA algorithm. second is transfort module using stream socket. the last module is graphic module. This paper describes cipher algorithm which can be used restrict condition for the same secret service with wire internet. we made a authentication module using based client and server system.

Recently, growth of internet causes rapid changes in many areas of statistics such as statistical computation and analysis. Especially, bootstrap is the most interesting statistical methods applying computer resampling simulation. In this paper, we try to present how to use a method of bootstrap on the internet. We also develop to user a statistical system which is programed with ASP for user to handle easily in manufacturing system.

This paper introduces a Web-based vibration analysis system for rotary-type refrigerator compressors. Concern for vibration reduction in compressors has been growing for many years. What is important in vibration reduction is to easily predict the vibration without using a physical compressor. The dynamic model of the compressor is represented as a multi-body dynamic system. Solving the dynamic model is run on a high-performance server. The interfaces of the system are accessible via Web browsers, such as Netscape or Explorer. Anyone who wants to analyze the vibration of the rotary compressor or share the results data can access the system over the Internet regardless of their OS, platform. or location.

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.
