A turnout serves to switch train from one line to another. The turnout consists of a Point which is switchs the rail to induce direction, and a Crossing which is cross over two line on the plane surface, and a Lead where is middle section in Point to Crossing. Point machine, consists of a turnout, is important facilities in railway signal, that is safety issue relates in derailment of the train. Recently, train delay and accident frequently occurred because of the turnout include in a point machine trouble of electrical and mechanical. So in order to prevent train accident the research is advanced, install of normal and reverse indication lamp in a point machine, development of adherence detector for sensing the status of adhesion between the stock rails and tongue rails etc. In this paper investigates the problem which is connected with a turnout trouble, include in a point machine, occurrence at the time of train accident, and then proposed to the safety system model in order to prevent the train accident in turnout.

PID Control Data Base creation device of DCU is safety operation technology of train door. For keeping the normal condition of door, measured value of regular condition and unusual(trouble detected) condition should be recorded by encoding. The door should be measured itself as this value is compared with standard vale. If it's condition of the door and for reaching the datum point and ot does self-diagnosis. This aim for Technical Realization is that carry out safety train operation by using the Estimation Data Base and protect before door-trouble.

The present study aims to examine how the roles of teacher and learners affect the repair patterns of both teacher's and learner's utterances in English as a second language (ESL) classroom discourse. The study analyzed beginning ESL classroom discourse and found that the structure of repair seems to be greatly influenced by the roles of participants in a second language classroom. The teacher's repair work was mainly characterized by self-repair. In contrast, learners' repair sequences were predominantly characterized by other-repair. More specifically, self-initiation by the learner of the trouble source was cooperatively completed by the teacher and the other learners. Other-initiated and other-completed repair was the most prevalent form in the current classroom data, which was carried out by the teacher in both modulated and unmodulated manners. When the trouble sources were mostly concerned with the learners' problems with linguistic competence and information presented in the textbook, other-repair took place in a modulated manner (i.e., recasting and prompting). On the other hand, when dealing with learners' errors with factual knowledge, other-repair was conducted in an unmodulated way (i.e., 'no' plus correction).

가입자시설 집중보전 시스팀(SLMOS)의 데이터베이스 역할은 가입자 시설에 대한 모든 정보를 유지하며 최근의 정보를 신속히 변경, 추가해야 한다. 또한 수시로 발생하는 고장 정보에 대한 유지가 필요하다. 이에 대한 데이터베이스 시스팀은 SLMOS의 구조와 UNIX 시스팀 구조와의 양립성을 파악하여 이 기반위에 데이터베이스 시스팀을 구성함으로써 목적을 달성할 수 있으며, 시스팀의 확장과 운용상의 효율성에 대비한 분산처리 방식을 겹합구성함으로써 SLMOS에 적합한 데이터베이스 시스팀 구성을 보인다.

Recently, the development of diagnosis technique with high confidence is important on power equipment, for this reason is to use for measurement and analysis of PD with prior appearance of insulation breakdown In this paper, we presents the analysis of trouble signal to use both method of general analysis of $\Phi$-Q-N in PD and statistical parameter by this interpretation Equipment of simulation has made independently DS for 170kV GIS of one phase with same on field. The detected signal through the sensor of Induction and Acoustic Emission is classified which used to characteristic neural network algorithm and then it is analysis.

클러스터 시스템의 노드 수가 수백에서 수천노드와 같이 대규모라면 시스템 관리에 많은 수고가 필요하다. 특히 노드 수가 많으므로 발생하는 빈번한 장애에 대하여 체계적인 장애관리가 필요하다. 본 논문에서는 대규모의 클러스터 시스템 환경에서 노드에 장애가 발생하는 시점부터 복구까지 체계적인 장애관리를 위하여 장애관리시스템(Trouble Management System, TMS)을 설계하고 구현하였다. 본 시스템으로 장애를 체계적으로 관리하여 효율적인 클러스터 시스템 관리에 도움이 될 것이다.

본 논문에서는 플랜트에서 발생되는 각종 노이즈의 장해사례에 대한 원인 분석과 대책을 제시하였다. 이들 노이즈 장해 현상은 각종 설비들의 오동작과 소손 등을 일으키며, 그 원인은 주로 노이즈를 차단하기 위한 방호소자의 부적절한 적용과 접지계통의 다원화에 의한 전위차에 기인한 것으로 분석되었다. 따라서 이러한 문제해결을 위해 본 연구에서는 적정한 방호소자의 선정과 설치, 접지계의 단일화에 의한 등전위 구성 등으로 노이즈 문제를 해결하였다.

Increased cumulative running times of railroad vehicle brings out such degradation as wear and fatigue. It don't adapt corrective maintenance which repairs a poor pan after a trouble but use preventive maintenance which fixes a bad part before a trouble. There were a few researches for preventive maintenance such as inspect affairs and facilities management. They couldn't estimate the operation reliability on railroad vehicle. Therefore, this study proposes the preventive maintenance procedure that predict repair period of end beam for uncovered freight car using reliability function and instantaneous failure rate on the basis of fatigue test and load history data.
