This study was surveyed among 1136 respondent of high school girls in seoul from Feb. 6, till Feb. 22, 1992 for the purpose of analysing the smoking of high school girls and its factor. The data was analied by X²-test and Multiple Regression and shows the following. 1. Out of 1,136 respondent, the current smokers were found to be 176, 15.5% and the former smokers were 204, 18.0%. This implies that 23.5% of high school girls seoul have experience smoking. 2. For the first smoking time in both smoking group and former smokers, it shows that the third grade of middle school lead the lists. 36.9% (65) of the smokers and 37.3(75)of former smokers experienced the first smoking at that time. 70.5%(124) of the smoking group have the intention to stop smoking and the first reason of it is health problem, 65.6%(75). 3. For the type of the school the smoking rate rages from 2.7%(7) of literary part in day time to 25.3%(97) of vocational part in evening time and the rate of smoking experience shows from 9.9%(26) literary part in day time to 25.3%(97) of vocational part in evening time. This data show that literary part in day time has the lowst rate while vocational part in eveing time the highest rate. 4. Compared with non smoker group, smoking group and former smoking group spent more money (P<0.001) and felt dissatisfied with school life and didn't have good school records. 5. Smoking group and former smokers have more boy friends than non smoking group and in most cases their boy friend have smoking habits (P<0.001) and it is the same with their gril friend (P<0.001). 6. Compared with non smoker group, smoking group and former smokers lack of their parents' interest (P<0.001). But whether it is strict or free there is little difference among the three group. 7. For smoking group and former smoking group, in most cases their parent, brother and sister tend to smoke and especially their sisters' smoking has much influence on their smoking in comparison with non-smokers. 8. Compared with non-smoker group, smoking group and former smoking group tend to think less of the harm of smoking. In regard with health problem, more smoking group and former smokers think that smoking can relieve the stress (P<0.001), and more non-smokers know that when a pregnant woman smokes, it can cause the lack of supply of Oxygen{P<0.01). 9. Smoking group and former smoking group have more positive attitude towards smoking than non-smokers and tend to agree to their boy and girl friends' smoking(P<0.001).

본 연구는 청소년의 자존감이 노동참여와 어떤 관계가 있는가를 분석하는데 그 목적이 있다. 연구 결과는 다음과 같다. 첫째, 자존감이 학년별로 차이가 있는가를 분석한 결과 자존감(긍정)은 학교 밖 학생들이 가장 낮았고, 재학생은 학년이 높을수록 자존감이 높게 나타났다. 둘째, 자존감에 대한 성별 차이에서 남학생이 여학생보다 자존감(긍정)과 자존감(합계)에서 다소 높게 나타났다. 셋째, 자존감과 노동참여 관계를 분석한 결과 자존감이 낮은 집단에서 아르바이트 경험이 있다고 응답한 비율은 50.4%, 자존감이 높은 집단에서는 50.6%이었다. 자존감의 높고, 낮음이 아르바이트 경험과는 차이가 없는 것으로 나타났다. 넷째, 아르바이트 의향과 자존감과의 관계를 분석한 결과 아르바이트 의향이 있다고 응답한 학생 중에 자존감이 낮은 집단의 비율은 50.5%이고, 자존감이 높은 집단의 비율은 49.5%이었다. 따라서 자존감의 높고, 낮음이 아르바이트 의향과는 차이가 없는 것으로 나타났다. 마지막으로 아르바이트 이유와 자존감과의 관계를 분석한 결과 자존감이 낮은 집단에서 아르바이트를 하는 이유가 경제적 이유가 아닌 자발적 동기인 경우가 68.1%이고, 경제적 비자발적 동기인 경우가 31.9%이었다. 또한 자존감이 높은 집단에서 아르바이트를 하는 이유가 경제적 이유가 아닌 자발적 동기인 경우가 75.2%이고, 경제적 비자발적 동기인 경우가 24.8%이었다. 자존감이 높은 집단이 자존감이 낮은 집단에 비해서 자발적 동기가 높고, 비자발적 동기가 낮게 나타났지만, 통계적으로 유의미한 차이는 나타나지 않았다.

The aim of this paper was to diagnose Korean college students' listening skills on the TOEFL. The researchers identified which section, among the TOEFL listening Part A, B, and C, is most easily teachable/ improvable during the period of a semester. First, the result of this research shows that Korean students tend to have lower scores in Part A than Part B or Part C. The results indicate that the short informal conversation doesn't give sufficient clues to students, and they don't have enough time to infer the answer. Second, the results revealed that. students showed the lowest progress in Part B after they studied TOEFL listening items and essential idioms for the listening section for 13 weeks. Because students didn't have much experience learning the informal conversation as opposed to the formal one in English, it is harder to achieve an improved grade in Part B, which consists of the informal conversation. But after a semester-long listening course, the average score on TOEFL listening sections increased.

The gas-assisted injection molding process is often perceived to be unpredictable, because of the extreme sensitivity of the gas. Since a slight change in design or process parameters can significantly change the resulting gas penetration, few designers and molders have the level of experience with the new gas-assisted injection molding process required for the development of new parts. This paper is concerned with the unified molding for a thick cosmetic chest by using gas-assisted injection molding. CAE analysis was carried out to design the part and the gas channel without inducing sink marks. And based on the part weight measurement, the processing parameters to control gas penetration percentage were chosen through the method of design of experiments. A thick cosmetic chest was successfully produced using the gas assist technology. The sink mark issue associated with the conventional injection molded parts was resolved. Weight savings and cycle-time reduction were also achieved.

Rapid Prototyping has made a drastic change in all industries which needs to reduce the time for the development of new products. Orientation and packing in rapid prototyping is considered as the most important factors to maximize the utilization of space in the build chamber and reduce build time. However, the decision of these parameter is mainly dependant on the operators's experience. This paper presents the methodology to find the optimal build layout considering an orientation and packing of multiple parts in SLS processing. Each part is represented as a voxel structure to deal with the inefficiency in a bounding box approach. Test results show that the adapted BL algorithm with a genetic algorithm(GA) can be applicable to a real industry.

재미있는 게임을 만들기 위해 다양한 측정기법들이 개발 과정에서 사용된다. 경험적인 부분에 대해서는 측정 및 분석이 어렵기 때문에 일반적으로 데이터를 수치화하기 쉬운 부분에 대해서만 측정, 분석하게 된다. 이는 게임의 재미는 경험적인 부분이 중요하다는 점에서 한계가 명확한 방법이다. 본 연구는 게임을 진행하는 사용자의 경험을 손쉽게 수치화하기 위하여 게임 사용자의 안면을 인식하고 인식된 정보로부터 감정 변화를 측정하는 기술을 활용하는 시스템을 제안한다. 시스템은 게임을 진행하는 사용자의 안면으로부터 실시간으로 감정을 인식하고 수치화하여 기록한다. 이렇게 기록된 데이터에는 시간 및 게임 진행과 관련된 수치, 안면으로부터 인식된 감정에 대한 수치 등이 포함된다. 기록된 데이터를 이용하면 특정 시점에서 게임이 사용자에게 어떤 감정을 유도하는지 판단할 수 있게 된다. 본 연구의 시스템을 활용하여 기록된 경험적인 부분에 대한 수치 데이터는 게임을 개발자의 의도대로 개발하는데 도움을 줄 수 있을 것으로 기대한다.

An Operating Experience Report(OER) has written about events and accidents happened at a Nuclear Power Plant(NPP). The purpose of publishing the OER is to prevent the similar event or accident repeatedly by spreading the experience of a single plant to other plants personnel. In this paper, it is analyses that the foreign NPPs' OERs on JIT published by the International Nuclear Agency(WANO, INPO, COG, BE). The analysis introduced in this paper is performed along with the various factors such as type of work, root-cause, and equipment. The root-cause analysis about the OERs shows that the Human-error is the major factor in foreign NPPs, but on the other hand equipment problem is the main part of the Domestic NPPs. The ratio of the foreign NPP's OERs on JIT according to the type of work was applied to KHNP-JIT developed nowadays for the first time in KOREA.

Most of Static electricity forms part of our daily experience broadly. Most people have noticed from time to time electric shocks when closing of their car or after walking across a carpet, operating shredder in winter and touching a metal handle. This electrostatic discharge nuisance is normally a minor inconvenience, but in some cases static electricity can cause more serious problems. Static electricity can also be harnessed to good effect in Position Control System.
