Objectives: For the purpose of preparing the fundamental data and assessing the status of exposure level of chemical substances in painting process. Methods and Materials: The author determined the concentration of organic solvents, lead(Pb), Chromium(Cr), and Toluene-2, 4-diisocyanate(TDI) in air of painting process to 90 industries classified by 15 types of manufacturing industry during a period from Jan. 1st 2001 to Dec. 31st 2001. Results: The results were as follows: 1. The geometric mean level of each chemical substance was 0.1706 ppm for exposure index in organic solvents, 0.0019㎎/㎥ for Pb, 0.0024 ㎎/㎥ for Cr, and 0.0004ppm for TDI, respectively. 2. The exposure level of each chemical substances by type of painting was the highest in dipping and brush painting for organic solvent, in spray-painting for TDI, and in spray gun-painting for Pb and Cr, respectively. 3. The exposure level of each chemical substances by type of local ventilation equipment was higher in enclosed and booth type for organic solvents. Cr, and TDI, and in exterior type for Pb, respectively than those of other types. 4. The exposure level of each chemical substances by type of hazardous material arresting media was higher in using water for organic substances, in using bag filter for Pb, TDI, respectively than those of other types.

현대 박물관 건축에 나타나는 상징성의 유추 근거와 구현 방식

This study shows how an architect, when he designs a museum, analogizes symbolism and clarifies relations between the basis of analogy and its characteristics through the classification of materialization methods of symbolism. The basis of analogy can be divided into two groups: ①an analogy based on internal reason like an exhibition program; ②an analogy based on external reason like a sense of place. Two materialization methods are a symbolism expressed partially and a symbolism expressed wholly. The former can be classified into two cases: ①disposition of a specific object in the foreground; ② exposure of sheds or skylights. The latter can also be divided into two: ① imagination of a museum formally; ②consideration of a sense of place. Among them, the example which considers a sense of place corresponds to an analogy based on external reason, the others are results of an analogy based on internal reason. In the case of the analogy based on internal reason, a museum can catch sight of visitors easily due to a distinction against neighboring context. In the case of the analogy based on external reason, a museum can be harmonized easily with environment formally or metaphorically.

Modern Dramaturgy: Chekhov's The Three Sisters and O'Neill's Long Day's Journey into Night

李龍官 水原大學校 1997 論文集 Vol.15 No.-

본 논문의 목적은 소위 Ibsen에게서 비롯되었다고 간주되는 현대극이 Chekhov을 거쳐 O'Neill에 이르기까지 어떠한 극적 기법의 변화와 차이를 보이고 있는가를 고찰하기 위함이다. Chekhov의 The Three Sister와 O'Neill의 Long Day's Journey into Night는 아리스토텔레스적 전통에 입각한 Ibsen극과는 달리, 잘 짜여진 외부구조를 갖고 있지 않다. 그러나 그것들은 외견상, 산만한 외부구조를 각기 독특한 내부구조로서 극복한다. Long Day's Journey into Night는 시각적인 꿈과 안개의 내부구조, The Three Sister는 청각적인 음향효과의 내부구조를 사용하여 과거, 현재, 미래의 시제를 자유로이 넘나든다. 본고는 이러한 내부구조를 조성하는 요소들이 어떻게 효과적으로 어우러져서 극적 효과를 자아내는지 연구한다.

李勇仁,權光善,權五奭 忠南大學校體育科學硏究所 1986 體育科學硏究誌 Vol.4 No.1

As upward kip motion is the basic motion on parallel bars, it is easily trained in the classes of physical education. The purpose of this study is to offer some useful data for teaching and improve the skill of upward kip motion . For this study, two members of the national team and a high-class male player in University were sampled at random. their motion was photographed with 16mm movie camera(48frames/sec) and the gravitational censer of the body was searched for through the drawing figure method. Upward kip motion was divided into 3 phases. And then the movement of the center gravity and the angle change of joint were analyzed and compared with mechanical method. The conclusions are as follows : 1. In phase 1, when kipping legs form an angle of 90 degrees with the parallel bars, the moving speed of center gravity on Subject A was 2.4 m/sec. that of Subject B 2.1 m/sec. that of Subject C 2.4m/sec. As we have seen, Subject A and C were of the same speed. and Subjects B was 0.3m/sec later than Subject A and B, so that I think that the moving speed of the conter gravity must be fast. 2. In phase 2. when the legs are in parallel with the parallel bars. hip joint angle of Subject A was Flex 151° degrees. Subject B Flex 136degrees, Subject C Flex 144 degrees. There fore I think that the legs must extend extend the most. 3. In phase 3, when the motion was perfected, elbow joint angle of Subject A in the last frame was Flex 178degrees, Subject B Flex 170 degrees, Subject C Flex 177degrees. Subject B was shown unstable motion because flexed more than Subject A and B . 4. The perfection of the upward kip motion in the parallel bars depend on the moving speed of body gravity when the kipping legs form an angle of W decrees with the parallel bars. the size of elbows angle. hip angle. and shoulder angle when the legs are in parallel . flexion and extention of elbow joint when the motion was finished, and the waste of the P. and F.

Try to find a scheme for activation to College Physical Education, this Report informs the various kinds of Survey and process those were projected for improvement of management methods on Cultural Physical Education in Kang Weon National University. From experimentally carried out "Sports events Choosing System" not as usual be inforced "Total practical Skill System", Following Positive effects and sujestions were Presented; 1. "Sports events choosing system" gave birth to more students' interesting and more voluntary participation to the sports events they chose, and sports skill and instruction level was elevated due to charge of expert according to each sports events. This system would be managed continuously hereafter for it related to life sports. 2. This System needs to closed cooperations between College and Community, for the facilities of community are utilized by college. 3. To complete the plan for activation of college Physical Education, additionally, the successional study ; namely "autonomous extracurricular sports activity" should be excuted hereafter.

Coevaporation에 의한 cd₁-xZn_(x)S 박막 제작 및 특성에 관한 연구

李載亨,李虎烈,朴鏞冠,申成浩,申載爀,朴光子 성균관대학교 1998 학술회의지원논문목록집 Vol.1998 No.-

In this paper, structural optical and electrical properties of Cd_(1-x)Zn_(x)S thin films prepared by coevaporation method were studied. Also, effects of ZnS mole ratio(x) to CdS on properties of thin film Cd_(1-x)Zn_(x)S/CdTe solar cells were investigated. When the ZnS mole ratio was less than 0.85, the crystal structure of Cd_(1-x)Zn_(x)S films was hexagonal with the c axis aligned perpendicular to the substrate. For x>0.85, however, the Cd_(1-x)Zn_(x)S films were grown with cubic zincblende structire. As the ZnS mole ratio increased the lattice constant of Cd_(1-x)Zn_(x)S films rapidly increased with ZnS mole ratio. The open circuit voltage of Cd₁xZnxS/CdTe solar cells increased with x due to reducing of the electron affinity difference between Cd₁xZnxS and CdTe films. However, the increase of series resistance due to the high resistivity of Cd_(1-x)Zn_(x)S films results on reducing conversion efficiency.
