This paper proposes a method for improving efficiency of high-voltage motors off-line insulation diagnostic test. The conventional manual test method has measurement errors and excessive processing time. We developed the KITAS system and solved these problems by using the instrument remote control and communication technology. The result of proficiency testing by interlaboratory comparisons using Power Factor Tip-Up test was '${\mid}E_n{\mid}$ < 1'. It was possible to confirm the validity of acquired data from the KITAS and establish a remote diagnostic system for easy access without physical limitations.

Objective: The purpose of this study is to identify the strengths and problems of the current in-service education system, and suggest ways to improve it in the future by looking at the current status of in-service education to strengthen the expertise of teachers and directors of childcare centers. In particular, I would like to search the current status of in-service education, including on-line special job competency education, which is responsible for one of the pillars of in-service education, and present the problems and measures to improve them. Methods: To that end, the present study conducted an analysis of issues based on the previous research on in-service education of childcare teachers' education, and conducted a literature examination focusing on laws, policies, and foreign cases related to in-service education. Results: In-service education for childcare teachers was categorized into educational process diversification and professionalism, educational method diversification, qualification management, and educational support, which were again organized into 14 core tasks. In addition, as a recent phenomenon that has not been discussed in detail in the preceding study, the phenomenon of increased participation in on-line special job competency education at the site of in-service education was analyzed and the problems were presented. Conclusion/Implications: Based on the results of this study, I proposed development measures such as changing the term 'in-service education' and recognizing the diversity of job competency education, the credit rating banking system for job competency education, the provision of on-line job competency education curriculum (basic courses/enhancing courses) for collective education courses, the expansion of education support for promotion to a higher grade courses and the conversion of the mandatory evaluation system for in-service educational institutions.

지금까지 대부분 전자계산기를 사용코저 하는 사람, 즉 user가 직접 전자계산소에 가서 service를 요청하면, 계산소에서 필요한 처리를 하여 그 결과를 용지에 인서하여 user에게 수도하는, 즉 off-line batch처리방식이 위주였다. 그러나 KIST등 일부에서는 중앙의 전자계산소와 통신선으로 연결된 user의 원격단말장치(remote terminal)에 의하여 user가 직접 계산소에 가지 않아도 이 단말장치에서 service를 받을 수 있는 on-line방식이 시도되었으며, 최근에는 대한항공회사의 항공좌석예약 on-line real time system과 외환은행의 은행창구업무 on-line real time system의 개발이 결실을 보기에 이르러, 우리나라에서도 이제 본격적인 정보사회의 모습을 갖추게 될 단계에 다달하게 되었다. 따라서, 여기서는 on-line real time system의 개념을, 이 방면에 관한 지식이나 상식이 없는 회원을 위하여 되도록이면 쉽게 해설코자 한다.

The advent of the Internet and the enormous increase in volume of electronically stored information (SGML, Image, Sound, etc.) has led to substantial work on IR(Information Retrieval). To service on the WWW, construction and retrieval technology of SGML, which is the fundamental standard data format for CALS/EC, is needed specially. Due to such a change, it becomes essential to change the existing paradigm of conventional information retrieval systems and to adopt new Internet service system with search engine, SGML browser and advanced Internet technology on WWW. KIPRIS(Korea Industrial Property Rights Information Service), which is the specialized and integrated Internet service systems in the field of industrial property rights information service, is trying to be a guide for our country to establish its technological competitiveness with providing the online service of high quality. The objective of the paper identifies features and technologies of KIPRIS IR(Information Retrieval) system based on WWW as follows. First, it describes the development background and process of KIPRIS. Second, it presents a fundamental technology that consists of IR(Information Retrieval) concept, BRS(Bibliographical Retrieval System) search engine, SGML implementation technologies and the Internet/WWW technologies. Third, it provides information about system configuration, architecture, and the features and characteristics of KIPRIS. Finally, the implemented KIPRIS system is introduced.

This study developed the algorithm of location-based service for supplying the efficient tourism service to traveller using mobile device and applied it to the Jeonju HANOK village. First, the location service was advanced using algorithm coupling with GPS error range and travel speed in single line, and with GPS location and nearest neighbor method to line in multiple one. Also this study developed a program using DuraMap-Xr spatial engine for establishing topology to Node and Link in line automatically. And the foundation was prepared for improving travel convenience by programming location-based service technology to single and multiple lines based on Blackpoint-Xr mobile application engine.

Recently, xDSL(x Digital Subscriber Line) service has got more and more interest not only in Korea but also all around the world. Many of telecom service companies around the world began to supply ADSL service, a kind of xDSL. And VDSL has been emerging as the next-generation technology of this ADSL. VDSL is very hish bit rate digital subscriber line and the fastest service of xDSL. VDSL is enough to service IP Multicasting, VoD, Broadcast video and etc. which become more important. In this paper we'd like to help making most suitable situation of Internet service by designing this VDSL networks architecture.

Background: The aim of this study was to examine the relationship between improvements in lip asymmetry at rest and while smiling after orthognathic surgery in patients with skeletal class III malocclusion. Methods: This study included 21 patients with skeletal class III malocclusion and facial asymmetry. We used preoperative and postoperative CT data and photographs to measure the vertical distance of the lips when smiling. The photographs were calibrated based on these distances and the CT image. We compared preoperative and postoperative results with the t test and correlations between measurements at rest and when smiling by regression analyses. Results: There were significant correlations between the postoperative changes in canting of the mouth corners at rest, canting of the canines, canting of the first molars, the slope of the line connecting the canines, and the slope of the line connecting first molars. The magnitude of the postoperative lip line improvement while smiling was not significantly correlated with changes in the canting and slopes of the canines, molars, and lip lines at rest. Conclusions: It remains difficult to predict lip line changes while smiling compared with at rest after orthognathic surgery in patients with mandibular prognathism, accompanied by facial asymmetry.

In this study, we newly classify services and service products in EC into Mass Service, Interactive Service, Ordering Service, and Professional Service. For classification, five selected variables and two factorized dimensions such as 1) ease of on-line interaction and 2) needs of on-line interactions are used. On the result of classification, we investigate the relationships with customer purchase intentions in EC. For this purpose, customer surveys were conducted on the respondent groups who are known to be frequent purchasers in EC and have advanced knowledge on services and service products. The survey is analyzed by statistical methods such as factor score plot, cluster analysis, analysis of variance, etc.

The trial business of e-trade service providers for supporting small enterprises to find their markets abroad is about to begin from the end of March, 2003. The department of Industrial Resources held the "Committee of e-trade service provider selection" with professors of e-trade field, and selected three companies: ECplaza, EC21 and Tpage Global. The e-trade service providers combine the various technologies of on-line trades and off-line trades to support small enterprises with lack of marketing skills by intermediation of overseas buyers and production, registration of e-catalogs and offers, administration of inquiries, trade negotiations, and contract settlement. Prospective small enterprises with exports under US$ 5 million will be selected by 2005. The selected companies will be supported fully by the government, and will be provided with the services by the e-trade service providers. e-Trade service will be the most potential and successful ones in the future, which helps traders and organizations preparing for globalization.
