Undesired trouble such as chatter vibration and burning on the ground surface appears frequently in the cylindrical plunge grinding process. Establishment of a credible fault diagnostic system for the grinding process is the major purpose of this study. Power signals generated during the grinding operation were sampled and analyzed to determine the relationship between grinding troubles and behavior of signal changes. In addition, a neural network was optimized with a momentum coefficient a learning rate, and a structure of the hidden layer through the iterative learning process. Based on the established system, success rates of the trouble recognition were verified.

In a power plant, it is generally accepted that a turbine governor system is necessary to control amount of steam supply toward the turbine system. There are many kinds of trouble at this governor system, which is recognized one of the most sensitive systems in the power plant. Especially we have experienced the internal leakage of motorization oil of servo valve. In the study, we investigated the mechanism of an internal leakage such as erosion by foreign materials and corrosion by chemical reaction between chloric healed oil and motorization oil. A precautionary measures is also performed to help the field service engineers.

Eleven junior-college students in Seoul who are interested in a drama volunteered to take part in the sociodrama. Their ages range between 21 and 35-all not married. The drama was performed 14 tiems. In the sociodrama test the conflicts between parents and their children and between siblings appear to be the factors of uneasiness and trouble. Parents' nrgative attitudes and the conflicts between siblings in childhood are the factors of the conflicts of the children in adolescence. This study is summarized into the following two points. 1. Parents' negative attitude toward their children in childhood can be the cause of the conflicts of their children in adolescence. 2. THe sociodrama is a very effective way to find the trouble between parents and their children and to search for the solution to it.

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).

이 연구는 최근 우리사회에서 급속도로 확산되고 있는 제노포비아에 대한 문제점을 살펴보고 경찰의 대응방안을 찾고자 하는 목적의 연구로서, 연구의 목적을 달성하기 위하여 제노포비아 관련 선행연구 및 관련통계를 활용하여 문제점을 살펴보고 경찰의 대응방안을 제시하였다. 제노포비아란 자신이 속해있는 지역에 편입되는 이방인에 대한 부정적인 반응으로, 동질감을 느낄 수 없는 이방인들에 대하여 혐오하는 태도나 행동을 의미하는 것이다. 국내에서 발생하는 제노포비아는 현재까지 큰 사회문제가 된다고 보기는 어렵지만, 향후 심각한 범죄를 발생시키는 요인으로서 가능성을 가지고 있어 제노포비아를 제거하거나 억제시킬 수 있는 방법을 연구 중에 있다. 우리나라에서 발생하고 있는 제노포비아는 이주노동자의 증가, 외국인에 의한 범죄 증가, 저소득국가 출신자에 대한 부정적인 태도, 원주민들과 이주자들의 충돌과 함께 낮은 다문화수용성 등으로 인하여 제노포비아를 확산되고 있다. 특히, 무분별한 제노포비아의 확산은 무시 차별에 의한 외국인 범죄의 증가와 원주민과 이주민간의 충돌이 빈번하게 발생하고 경찰이 투입되어야 하는 상황이 증가하고 있다. 이러한 문제에 대하여 이 연구에서는 경찰의 대응방안으로 제노포비아에 의한 범죄 발생 시 관련법의 확대해석을 통한 처벌과 제노포비아를 조장하는 각종 매체에 대한 적극적인 대응, 제노포비아를 유발하는 이주민과 내국인과 충돌을 예방할 경찰활동 강화와 외국인범죄 예방방안을 제안하였다.

애니메이션은 전체적인 서사구조 속에서 캐릭터의 미적특징과 행동이 융합되어 표현되며, 이와 같은 캐릭터의 창조는 그것을 탄생하게 한 사회문화적 배경과 극적 구조 속에서 심리학적 접근이 필요하다. 본 연구는 애니메이션 캐릭터 창조에 있어 보다 현실성에 바탕을 둔 캐릭터를 형상화합과 동시에 개성적이고 독창적인 캐릭터와 네러티브 개발의 필요에 의해 시작되었다. 본 논문에서는 미국 정신의학회의 DSM-IV 정신장애와 진단 및 통계편람 을 통해 애니메이션 캐릭터의 성격장애를 분석해 본 결과 캐릭터의 성격유형은 일반적인 경향보다는 과장되게 표현됨으로써 극적인 동기유발과 극에 있어서 개연성을 위한 도구로 쓰였다. 또한 애니메이션 캐릭터에 성격장애와 같은 증세를 성격에 부여받음으로 네러티브 전개에 있어 변화를 가져 왔으며, 애니메이션 캐릭터가 비록 성격장애는 아닐지라도, 성격장애와 같은 기질이 과장 혹은 증폭되어 나타나고 있음을 알 수 있다.

Several aspects of conscious about somato-type were analysed for high school girls among Seoul, Kwangju, Wando. Questionnares was comprised of 24 item of the conscious about somatotype. Questionnaress were sent to sample of students of high school. The data from 593 respondantss were analysed in using Freequency, Crosstab, and T-test. The results were as follows: 1. High school students in Wando tend to have shorter and fatter than Seoul and Kwangju. 2. Respon-dents were conscioused of , , . 3. Of the trouble of somatotype, respondents of all region have troubled about , , , , It was founded that Respon-dents in Seoul have much the trouble about , than other regions. 4. Mean of Agreement of somatotype were scored 3.49 in Seoul 3.37 in Kwangju, 3.39 in Wando. It was founded that respondents in Seoul were not satisfied more than Kwangju, Wando. And then Respondents in Seoul have strong aspiration to be slim about somatotype although they are a stansard somatotype.

As the noise of ship engine room is too loud, the engineer who works in a ship engine-room has the trouble of hearing. In this paper deals the investigation of the noise of ship engine room and cabins with the internationally allowable noise exposure level and noise exposure time. Recently, the problem of engine-room noise is more serious because of shipowner wants to make small number and larger size of cylinder. Therefore, engineers work in a ship engine-room for a long time have the trouble of hearing when they are exposed the high noise level. In this study, two kinds of vessels were used to investigate the noise of engine room, engine-control room, bridge, offices and cabins. As criteria of sound levels, A-weighted sound pressure level and octave band pressure level were used.

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.

The most part of the faculty drop a trouble and damage of machine equipment even if whatever cause they break out take place at local and trifling place and the factor dominating their trouble is due to wear debris occurred in the lubricated machine moving surface. This study has been car-ried out to identify morphology of wear debris on the lubricated machine moving system by means of computer image analysis. Namely the wear debris contained in lubricating oil extracted from movable machine equipment will be filtered through membrane filter(void diameter 0.45${\mu}m$) and will be analyzed with its data information such as 50% volume diameter aspect roundness and reflectivity. Morphological characteristic of wear debris is easily distinguished by four shape parameters it is necessary to divide small class of every 100 wear debris in total wear particles in order to distinguish morphological characteristic of wear debris more easily by computer image analysis. We are sure that operation condition diagnosis of the lubricated machine moving surfaces is possible by computer image analysis.
