The development of a Web-based powertrain performance simulation system is introduced. The development approach of system architecture and each module is introduced along with the H/W and S/W used. The interface with all users is developed via a JAVA applet. The powertrain modeling and other job history data of a user is managed systematically on the server by database to increase the reusability of the data. A self-developed program using object-oriented programming is used as a solver for the performance simulation. The graph tool for the analysis of simulation results has the collaboration support developed based on JAVA so that synchronous users can view the same result. As a result, the powertrain simulation is possible only with Web-browser for the user and the collaboration support among the relevant engineers is possible.

Materials property data are necessary to secure the reliability of failure prevention techniques such as inspection and remaining life assessment of civil infrastructure and industrial facilities. However, there is no properly collected data in Korea, and those foreign data are hard to use because of the scattering of the sources, the difference of standards, etc. In this paper, materials property database system which has been constructed at Korea Research Institute of Standards and Science is introduced. Constructed database contains 145,000 numeric data of materials property for 600 kinds of metals and can be retrieved on the internet. The database system provides graphical user interface-based information searching functions necessary for the life evaluation and safety analysis.

Web development and Internet technology development bring many kinds of works to web. This is the main reason why XML, document standard is popular. XML in web can be used to express document template or standard. XML with java can be more powerful and general. For example, XML can be used to transmit data and to print data into the screen using Ajax in JSP(Java Server Page) and to make interfaces in android, which is useful to reduce development cycle. However, XML is not easy to learn for the novice. In this paper, we propose the easy and effective way to reduce the learning curve of XML and to make and use XML documents. For the purpose, we suggest template base XML document generation and we design and implement XML document generator based on Template. XML document generator of template-based provides user interface and layout of XML document. So, users can generate XML document easily and effectively.

In this paper, the web-based monitoring system is developed for the process monitoring of mold manufacturing. The cutting force is measured by hall-sensors which is low cost and useful to be installed in machine tool indirectly. Specially, the current of main spindle in machine tool is converted into cutting force by various experiments. For effective emote monitoring, the interface that is able to offer the information of current process and cutting signal to client is establish.

웹 기반 교육 시스템은 정보의 일방적인 전달방식에서, 사용자와의 양방향적인 정보교환방식으로 변화되었다. 이에 따라, CGI(Common Gateway Interface)와 같은 서버측 언어와 데이터베이스를 이용하여 각 기능분리에 따른 3-계층 모델로 구현되어왔다. 그러나, 최근 CBSD(Component Based Software Development)기법이 많은 관심을 받으며, 이를 적용하려는 노력들이 나타나고 있다. 이에 따라, 본 연구에서는 컴포넌트 기반의 문제풀이 시스템을 구현하였다. 이를 위하여, 웹 서버측 컴포넌트 모델인 EJB(Enterprise Java Beans)를 이용하였으며, 컴포넌트들 사이의 메시지 흐름에 대한 정형적인 명세를 위하여 페트리 넷을 이용하였다.

This study describes the development of nursing education program on web-based instruction for Nursing Management Practice of nursing school. The program has been developed based on five steps of the teaching-learning design model developed by Chung, In-Sung which is widely used in Web-Based Instruction(WBI). The objective of this study was to develop nursing education program on WEI and to evaluate its effectiveness. The subjects consisted of twenty-four senior nursing students taking the Nursing Management Practice course. Two sets of questionnaires were used for this study. They were asked to evaluate the program in terms of appropriateness of the teaching strategy, precision of the contents, easiness of use, easiness of approaching system, interface design, system management, enhancement of communication, and effectiveness of learning. The program was developed in five steps, analysis of the student, design of the contents, production of the system, implementation of the system, and evaluation of the effectiveness. It is concluded that this program was very useful in increasing the effectiveness of learning and motivation in the students. In addition to this, the web-based learning system would be one of the best qualified educational method for nursing students. Therefore, I would suggest that it can be used for other nursing courses which is available on the Web.

웹 서비스를 기반으로 한 인터넷은 비약적으로 발전하고 있으며, 차세대 웹 표준화를 위한 노력이 전세계적으로 진행 중에 있다. 처음 개발된 당시 웹은 텍스트 기반의 구조에 맞추어 HTTP, HTML, URL이 제안되어 이를 통해 비동기적인 형태의 검색과 단순하고 단일한 방식의 표현 방식을 사용해 왔다. 그러나 최근 인터넷 상의 상당수의 데이터들은 보다 복잡해지고 구조화되어 가고 있으며 동기적인 멀티미디어 정보를 포함하는 등 새로운 구조 및 표현 방식을 요구하게 되었다. W3C의 사용자 인터페이스 도메인 중 멀티미디어 동기화 그룹에서 현재 표준화 작업중인 언어는 SMIL SMIL은 웹 상에서 멀티미디어 요소들이 잘 통합되어 어느 위치에서 얼마동안 표현되는지를 기술하는 XML-기반 언어이다. 본 논문에서는SMIL 관련 표준화 동향 및 주요 이슈들을 연구 분석하고 기술 개발 내용에 대하여 논의한다.

Recently, the conventional controller of machine-tool has been increasingly replaced by the PC-based open architecture controller, which is independent of the CNC vendor and on which it is possible to implement user-defined application programs. This paper proposes CNC­implemented fault diagnosis and web-based remote services for machine-tool with open architecture CNC. The faults of CNC machine-tool are defined as the operational faults occupied by over $70{\%}$ of all faults. The operational faults are unpredictable as they occur without any warning. Two diagnostic models, the switching function and the step switching function, were proposed in order to diagnose faults efficiently. The faults were automatically diagnosed through the fault diagnosis system using the two diagnostic models. A suitable interface environment between CNC and developed application modules was constructed for the internal function of CNC. In addition, a suitable web environment was constructed for remote services. The web service functions, such as remote monitoring and remote control, were implemented, and their operability was tested through the web. The results obtained through this research could be a model of fault diagnosis and remote servicing for machine-tool with open architecture CNC.

Home security has become the prime concern for everyone in present scenario. In this work an attempt has been made to develop a home security system which is accessible, affordable and yet effective.The proposed system is based on 'Remote Embedded Control System' (RECS) which works both on the web and gsm platform for authentication and monitoring. This system is therefore cost effective as it relies on existing network infrastructure. As PCA is most popular and efficient algorithm for face recognition, it has been usedin this work. Next to it an interface has been developed for communication purpose in the embedded security system through the ZigBee module. Based on this embedded system, automated control of door movement has been implemented through electromagnetic door lock technology. This helps the users to monitor the real-time activities through web services/SMS. The web service consists of either web browser command or e-mail provision. The system establishes the communication between the system and authenticated user. The e-mail received by the system from the authorized person will monitor and control the real-time operation and door lock. The entire control system is reinforced using ARM1176JZF-S microcontroller and tested for actual use in the home environment. The result shows the experimental verification of the proposed system.

최근의 웹 기반 교수-학습의 패러다임은 학습자의 능력, 적성, 요구, 흥미, 학습 이력, 학습 활동 프로파일등에 입각하여 학습자의 학습 패턴을 분석해내고, 학습자 개개인에게 적응적인 환경을 제공하는 방향으로 변화되고 있다. 본 연구에서는 학습 활동 데이터를 이용하여 학습자의 학습 패턴을 Apriori 알고리즘을 이용하여 분석해내고 학습자 개개인에게 적응적인 학습 환경을 제공하는 개인화 시스템을 개발하였다. 개인화 시스템은 학습경로, 인터페이스, 상호작용 개인화의 세 부분으로 구성되어있다. 개발된 개인화 시스템을 웹 기반 교수-학습 과정에서 학습자 개인의 학습 만족도를 향상시키는데 효과가 있는 것으로 나타났다.
