崔鍾三,金官鉉 龍仁大學校 1990 용인대학교 논문집 Vol.6 No.-
The frequency of technical application by weight class towards 370 athletes participated in the 1st Selection Match of the National Representatiues in 1989, Concurrenthy the 28th National Judo Championships by weght class, the frequency of technical application by weight class towards 265 athletes participated in the 1st Selection Match of the National Representation in 1990 and the National judo Champion for the 27th Presidential cup are studiet and avalyzed. The Hand Technique was mush used in the light weight, while the foot technique was mairly applied in the heawy weight auording to the presious srudy. As noted above this diferent from the previous research, both the Hand and Foot Technique were applied in the heavey and light weight in all the compplied in the heavey and light weight in all the competitions of 1989 and 1990. In the case of the application of the Foot Technique showed constauihy a high propation in all heavy weights, while in the heavy weight was much depended on GATAME in the defeat. 1) Extra Light Class Prior to the 1989s athletic match, it was applied in sequence of the Hand Technique (SEOI-NAGE), the Foot Technique (UCHI-MATA) and CATAME (KAMI-SHIHO-GATAME). As the result, it was turned out in the sequence of the Hand Technique, the Foot Technique, an GATAME (UDE-HISHIGI-JUJI-GATAME). 2) Half Light Class In the athletic match of 1989, the sequence was turned out to be the Foot Technique (KO-UCHI-GARI), the Hand Technique (SEOI-NAGE) and GATAME (HON-KESA-GATAME). According to the Athletic Comptition in 1990, the order was stood in sequence of the Foot Technique (O-SOTO-GARI), the Hand Technique (SEOI-NAGE) and GATAME (KAMI-SHIHO-GATAME). 3) Light Class While it showed an order of the Foot Technique (KO-UCHI-GARI), the Hand Technique (SEOI-NAGE) and GATAME in the Athletic mach in 1989. Also the Foot Technique, the Hand Technique and Nurugi were shown as its sequence in 1990. 4) Half Middle Class The sequence stood in order of the Foot Technique and the Hand Technique in terms of the Athlitic match of 1989 Also in the Athetic match was in sequence of the Foot Technique and the Hand Technique. 5) Middle Class The athletic competition has indicated its order as the Foot Technique the Hand Technique and NURUGI in 1989. Also in terms of its order the athletic meeting was the Foot Technique, the Hand Technique in 1990. 6) Half Heavy Class The sequence of the Foot Technique, the Hand Technique and the Waist Technique was applied the athletic competition in 1989. The athlitic completion in sequence was in order of the Foot Technique, the Hand Technique and the Waist Technique in 1990 7) Heavy Class It was used in the sequence of the Foot Technique, NURUGI(KOYT-NURUGI) and the Hand Technique (HOBOKTARI-KOLKI) in the athletic competition in 1990. Meanwhile, the sequence of on application in the 1990. athletic competition was in order of the Foot Technique (HOBOKTARI-KOLKI), the Hand Technique (BIT-DANGKY-O-CHIKI) and NURUGI (KYOT-NURUGI). Recommendations for Further Research There are several directions in which future research in this area could be pursued. Several proposals are conduction for on improvement of our internal Judo. 1) The contest in most cosets was determened either by the hand or the Foot Technique both in 1989 and 1990. Therefore, a variety of techniques are necessarily required to learn other than these techniques in the future. In addition, KUD-CHIKI will be able to exercise a great influence for ocitory. Further, the technique of KUD -CHIKI has to he more often applied. 2) Such technique as may be applied by other athletes shall be researched and improved, also individual player has to do its best in the development of the Korean Style Judo Technique is quite similor to KAWI -CHIKI. 3) A numver of investigators recommended in the foreyuing study, but the Judo player will be able to play more intensive style talon aim at the gaining of points. 4) It is even more desirous that the Judo players of may country have to concentrate extorts in the physical training in order to cope with the changing situation of the international Judo from the technical Judo to the Judo of strength. 5) Currently, the Juo Uniform had a narrow to take hold of during the contests, but the international Judo Federation has taken necessary measures to broaden the uniform's width in order to the athletes, therefore it is helieved argenthy necessary that Judo players are able to egage in the whole hearted devotion to an assault hased on the technique than to a struggle to take hold of its oppaonent.

일부 자동차 공장 근로자들의 職業的 特性과 社會 心理的 Stress의 相關性 硏究
김성삼,홍지우,한현정,최희석,권소희,정해경,김삼태,송용선,이기남 한국전통의학연구소 2004 한국전통의학지 Vol.14 No.1
〈Objective〉 This study were carried out to study to assess the relationship between job characteristics, general characteristics, health behaviors, and psychosocial distress and suggested the preventive oriental medicine approaches in occupational health area. 〈Methods〉 We measured job characteristics(job demand, job control, jop insecurity) by The Karasek's Job Content Questionnaire, health behaviors(smoking, drinking, exercise, coffee), general characteristics at work by a self-administered questionnaire. Psycho social distress was measured by PWI(Psychosocial Well-being Index), a 18-item self- administered instrument. 370 data for research were collected through the process of oriental health examination with questionnaire in workplace. Statistical analysis was done by t test, oneway ANOVA, and hierarchical multiple regression analysis with SPSSWIN (version 10.0) 〈Results〉 Among the 152 respondents, the prevalence of high job strain was 27%(41 persons). The Odds ratio of high job strain was 3.11(95 2.12~4.11), and those of passive group and active group were 2.01(95 0.83~2.76) and 1.80(95 0.83~2.76), respectively. Our results supported the association between psychosocial distress and job strain. 〈Conclusion〉 The odds ratio of high strain isolated group(high strain group+low social support) was 3.59(95 2.05 5.13), but the odds ratio of high strain collective group was 1.32(95 0.23 2.41). Social support at work was modifing factor of the association between psycho social distress and job strain. Therefore we reviewed the evidence that economic depression was associated with psycho social distress in this study, and that the strength of the social support was important in maintain health.

Soon Ki Kwon,Weon Jung Choi,Yun Hi Kim,Sam Kwon Choi Korean Chemical Society 1992 Bulletin of the Korean Chemical Society Vol.13 No.5
Several poly(alkyl methacrylate-b-t-butyl methacrylate) diblock copolymers were synthesized by group transfer polymerization. The molecular weight of poly(t-butyl methacrylate) segments and the composition of the resulting block copolymers were controlled by the monomer feed ratios and mole ratios of monomer to initiator. The poly(t-butyl methacrylate) block was quantitatively hydrolyzed to poly(methacrylic acid) block by refluxing with a catalytic amount of p-toluenesulfonic acid in dioxane at $100^{\circ}C$ for 12 hrs. The thermogravimetric analysis of poly(alkyl methacrylate-b-t-butyl methacrylate) exhibited the lose of isobutylene and subsequent anhydride formation in the range of $205-300^{\circ}C$.

Ehanol에 依하여 損傷된 胃粘膜 上皮의 回復에 關한 實驗的 硏究
최삼임,이혜수,고범권,장성강,강명재,조남표,조성남,김상호 의과학연구소 1992 全北醫大論文集 Vol.16 No.2
This study aimed to investigate muoosal damage and restitution in the rat stomach after absolute ethanol instillation. Four me. of absolute ethanol was instilled to stomach and gastric mucosa was exposed to it for 30 and 45second , and then examined at immediately, 10 minute, 30 minutes, 60 minutes and 6 hours. Morphological studies of gastric tissue were performed by means of epon-toluidine blue section, H&E, and periodic acid Schiff(pAS) stains. The results were as follows. 1. Immediately after exposure to absolute ethanol far 30· seconds(time 0), surface mucous cells and the cells lining the gastric pits were damaged and exfoliated, but the gastric gland cells were not damaged. 2. Immediately after exposure to absolute ethanol for 45 seoends(time 0), superficial epithelium was necrotic and cellular damage was evident in the gastric glands beneath the damaged surface and gastric pits. Some inflammatory reaction was also noted. 3. Hyperemia and hemorrhage in the gastric mucosa were evident in almost all experimental groups 4. Epithelial restitution was begun to observe at 30 minutes in both 30 and 45 seconds-exposure groups, and almost completely restituted at 60 minutes after ethanol exposure. Surface mucous cells in restituted area were somewhat different from normal mucous cells morphologically. 5. According to damage of surface mucous cells, cytoplasmic PAS-positive granules were markedly decreased, but the PAS-positivity was also restored with restitution of mucous cells(even if weaker reaction than in normal mucous cell). It is thought that absolute ethanol-induced mocosal damage is striking even if the exposure time is brief, and epithelial restitution is achieved for 30 or 60 minutes after ethanol exposure. The mechanism of epithelial restitution might be resulting from migration of undamaged epithelial cells.
