토지관리정보체계 구축사업은 1997년에 기본계획을 수립하고 1998년에 대구광역시 남구를 대상으로 시범사업을 실시하였다. 2001년 현재가지 12개 지역에서 구축사업을 완료하고 실제 업무에 활용하거나 시험운영을 하고 있으며 88개 지역에서 수행 중에 있다. 향후 2004년까지 전축 16개 광역시도와 232개 시 군·구에 토지관리정보체계를 설치 완료할 계획이며, 아울러 토지관리정보체계를 유지 관리하는 토지정보센터를 설치할 계획이다. 토지관리행정업무를 수행하면서 발생하는 많은 문제를 해결하는 수단으로써 정보기술을 도입하는 것이 토지관리정보체계 구축이다. 이를 위해서는 현재 아나로그 환경 속에 존재하는 모든 것을 디지털 기술환경에 적합하도록 전환시켜야 한다. 그러나 이는 간단한 일이 아니며, 특히 아나로그 환경 속에 있는 주체를 기본적으로 디지털 세계로 끌어들이는 것이 가장 어렵고 중요하다 따라서 아나로그 토지행정을 디지털 기술환경으로 어떻게 합리적으로 전환시키느냐가 토지관리정보체계 구축사업에서 앞으로 추진해야할 가장 중요한 과제라고 할 수 있다.

This paper surveyed 30 system designers and developers who had been participating in a project for five months to examine the usefulness of design artifacts for object-oriented system development. A set of nine requirement and design documents was selected in consideration of the IEEE guidelines. Overall the respondents appeared to agree that the artifacts were useful for system development. On the other hand, the contribution of design artifacts to maintenance was rated lower due to the frequent changes over the iterative process. Of the artifacts, considered more useful were use case specifications, UI design and operation specifications. The respondents were the most reluctant to write test cases. Designers did not like to document more details in the design artifacts than did developers. A future study is required to determine the economics end change management of documentation.

Configuration management plays a key role in systems engineering process for any project from earlier stage of development. It consists of five major activities, ie., configuration management planing, configuration identification, configuration control, configuration status accounting and configuration verification and audit, and is essential to control system design, development and operation throughout entire life cycle of the system development. And it is directly associated with other part of systems engineering management process, ie., technical data management which provides traceability of important decisions and changes during development. In this paper, we describe how to apply CASE(Computer-aided Systems Engineering) tool-Cradle for the configuration management to achieve effectiveness of Technical Management process.

This paper aims to explore effective ways to improve inspection service and develop customer-centered inspection administration, by carrying out a case study on the K Society of Ship Inspection. The methods applied for this research project are as follows, 1) sector-based examination of the existence of the ISO 9001 system; 2) evaluation of the operation of the system; 3) conduction of a survey questionnaire with the participation of all staff and inspections institutes to analyze customer satisfaction of their inspection service, and 4) statistical analysis of the data collected from the survey questionnaire.

The SRI (Super Resolution Imager) is the development project for the next generation satellite camera. This camera has more high resolution than the present satellite camera. It's used by very accurate observation and other multi-purposes. In this paper, the SRI electronic system is described in terms of H/W (Configuration and Function operation).

RIMS（Rolling Stock Information Maintenance System)　was installed in structure which it can analyze the data base in need of credibility maintenance. So it could accumulate real data without repulsion of working spot. Information system was installed not following to system but following to working spot. The development of RIMS project was started from March 29, 2001 and it has been operating from October 12, 2004 in Chang-dong Car depot for light maintenance in charge subway line4. So substantial data base was accumulated for three years. This study calculated all RAMS data by analyzing data base accumulated in RIMS and used in dada base about credibility maintenance and found investigation of propriety, expectation of the life cycle cost, the improvement plan on credibility of sorts of cars and formation about the cycle of repairing and maintenance. This got MKBSF MKBF and MTBF about devices and sorts of line4 Rolling Stocks for it.

Modern transmission technologies such as automated manual transmission(AMT) and dual clutch transmission(DCT) are interested to all manufactures due to their fuel efficiency and driver's convenience, especially in a hybrid system. AMT has advantages in that they have a high efficiency of manual transmissions(MT) and offer operation convenience similar to automatic transmissions(AT), but it has some disadvantages in that they have torque gap during gear shift and shift time. To reduce disadvantages, it is necessary to evaluate errors and characteristics as a developing simulation model before experimental verification. The purpose of this study is to develop virtual components and simulate the transient response of AMT. A dynamic AMT model and a control logic for an integrated vehicle model have been developed using Matlab/Simulink as a simulation platform. In this paper, the clutch model to describe the stick-slip transition mode and the transmission model to describe the neutral gear shifting is introduced and compared with each other.
