배상석,서성교,홍은식,김승모,조미정,한혜정,이두성,김세훈,민석홍 국립7개대학공동논문집간행위원회 2001 공업기술연구 Vol.1 No.-

The thermal decomposition process of Mo(CO)_6 on chemical vapor deposition was investigated by analyzing the effects of deposition temperature, pressure, and reaction gas on the phase change of deposited films. Mo_2C was deposited at or below 350℃ due to the incompleteness of thermal decomposition of Mo(CO)_6, but Mo films was successfully deposited at 400℃ or higher temperatures. The variation of deposition pressure did not change the dependence of decomposition process on deposition temperature. The activation energy of surface reaction was 5.8 ㎉/mole.

密度高度의 適用에 關한 考察

李晶模,朴溶寒 한국항공대학교 1985 論文集 Vol.23 No.-

Although most of the aircraft pilot understand that the accurate and practical flight performance can finally be determined by the air density they have tendency to neglect the recognition and the application of the density altitude as a measuring scale of the air density affecting directly to the actual flight performance. Probably this tendency is caused by the complexity of applying process of the D A factor for the actual flight and their general idea of thee resultant errors which would be small amount being negligible for the safety flying. This paper is to deal with examination dy reference to the applying method of the density altitude for the flight and to the anticipated errors of flight performance in relation to the computing process of the density altitude and is emphasizing the importance of density altitude for the pilot.

國內航空交通의 發展方向에 關한 硏究

李晶模,金七永 한국항공대학교 1989 論文集 Vol.27 No.-

GNP 上昇에 따라 사람들이 要求하는 交通서비스 질은 높아지고, 他 交通手段과의 競爭을 度外視한 상태에서는 시대흐름에 따라 變貌하는 交通市場需要를 充足할 수 없는 것이다. 국토면적이 좁은 우리나라의 경우, 道路産業의 發達과 鐵道産業이 高速化에 對應하여 航空交通 發展은 어렵게 되어있다. 따라서 交通需要增加 추세와 他 交通手段에 대한 敎通政策 등을 分析하여 需要變化에 따라 伸縮性있게 대처하기위한 不定期 및 一般航空機의 航空交通體系를 硏究하여 航空交通의 發展方向을 도출하였다. The service qualities of transportation must be raised with G.N.P inereasement because most people prefer to more comfortable and higher class transportation means. And the time is more worthy for a high - income people than another. In these circumstances air transportation have been developed remarkably. But it is doutful that air transportations are able to maintain a superior position in competitive transportation market because advanced high way expresses and super railroads are under the rapid improvement conditions. This paper is to deal with analysis the increasing tendency of transportation demands and other transportation policies, and suggestions for improvement of domestic air transportations.

XML 문성의 효율적인 미세 접근 제어 시스템을 위한 명시적 접근 권한 트리 생성 기법

이헌길,강정모 강원대학교 산업기술연구소 2003 産業技術硏究 Vol.23 No.A

차세대 웹 문서의 새로운 표준으로 자리 잡아 가고 있는 XML은 전자 상거래나 병원 관리 등과 같이 다양한 응용 분야에 적용되고 있다. 이러한 응용 분야는 XML 문서의 각 구성 요소 수준의 세밀한 액서스 제어를 요구한다. 따라서, 현재 XML 문서의 미세 접근 제어 기법에 대한 연구가 활발히 이루어지고 있다. 현재 제안된 XML 문서를 위한 미세 접근 제어 기법은 대부분 묵시적 권한 기법을 사용하여 상위 구성요소에 한번의 권한 부여로 하위 노드에 권한을 부여하는 효과를 가지는 장점을 가지나. 각 구성 요소간의 권한을 체크하는 시간 오버헤드를 가지는 단점이 있다 본 논문에서는 권한을 체크하는 시간을 감소시키기 위하여 XML 문서의 미세 접근 제어를 위한 명시적 권한 기법을 제안하고, 이를 이용하여 노드의 권한에 대한 모든 정보를 저장하고 있는 접근 권한 트리 모델을 제시하였다. 본 논문에서 제안한 접근 권한 트리 모델을 사용하면, 권한 정보를 저장하는 공간 오버헤드가 있지만, 권한 체크 시간을 감소시켜 사용자에게 보다 빠른 뷰를 제공할 수 있다.

경제발전과 GNP증가에 따라 여러 교통수단중 특유의 장점을 지닌 소형항공기의 수요가 증가 되면서 새로운 소형비행장 건설이 요구되고 있으며 이로 인하여 소형항공기의 소음영향도 새로운 문제로 부각되고 있는 추세이다. 본 연구는 비행기 소음이 Peak치를 나타내는 이륙시 엔진소음을 실측하여 활주로 부근의 소음분포를 분석 평가 하였으며 소형비행장 건설 및 운영에 필요한 소음영향평가 자료로서 도움이 될 것을 기대한다. With the increase of GNP the demand for small aircraft and the needs for small airfield increase considering small aircraft have peculiar merits. Owing to this, noise influences against small aircraft stand out in new problems recently. This paper attempt to take the accurate measurements of the engine noise levels of small airplane on the takeoff leg in which peak noises are produced. And the paper also analyzed and evaluated the distributions of engine noises made out on the basis of these measurements. It is to deal with materials for valuations of noise influences planning small airfield are being built or operated.

The purpose of this study was to evaluate the accuracy of CPR skills and the satisfaction of CPR Training targeted for college students. Also, this study made comparative study of nursing students and non-nursing students. The sample consisted of 248 students(132 nursing students, 116 non-nursing students). CPR Training was designed by two components which were a lecture and demonstration by one professor and individual practice 표 instructors. As tool of measurement estimation satisfaction of CPR Training questionnaires were developed based on educated contents. The accuracy of CPR skills were checked by SkillReporter CPR training manikin. Collected data were computerized and analyzed by SPSS-WIN program. The results were as follows : 1. The skills of CPR were cardiac compression 92.79 times/min, correct cardiac compression rate 90.85%, ventilation 9.93 times/min. correct ventilation rate 79.34%. 2. The mean of the accuracy of CPR skills were 2.94(SD .87). 3. When errors were analyzed, the highest item was stomach distension(51.2%) of ventilation skills and too little(70.6%) of cardiac compression skills. 4. The mean of the satisfaction of CPR training were 2.87(SD .17), the highest item of the satisfaction of CPR Training was practice. 5. We found significant statistical differences based on the accuracy and the error, non-nursing students were high in correct cardiac compression per minute(t=3.615, p=0...) and ventilation too much(t=4.292, p=.000), nursing students were high in correct ventilation rate(t=-3.885, p=.000) and cardiac compression too shallow) t=-2.842, p=.005).

The purpose of this study was to investigate school children's monthly incidence rates and causes of accident. The number of studied subjects were 279 school children. The results were as follows: 1. Average monthly incidence rate of accident for male was 17.8 per 100 persons, and that of female was 12.7. That of the 6th grade was 32.7, and the 1st grade was 5.6, and March was the highest in incidence rate of studied months. 2. The accidents occured most frequently in the 6th grade and relatively low in the 1st grade. 3. The presence of parents, their occupation, and education and monthly income of household were not affected school children's accident. 4. Time required and distance from house to school were concerned to children's accident. Walking was relatively lower than other way in the way of transport from house to school. 5. The majority sites of injury were legs & arms. 6. Most of injured children treated at the medical institute.
