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.

〈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.

Synthesis of Amphiphilic Poly(alkyl methacrylate-b-methacrylic acid) by Group Transfer Polymerization and Selective Hydrolysis

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 $205-300^{\circ}C$.

권경배,권삼,고희신,최성민,김두권,신형종,강승완,김우택 東國大學校醫學硏究所 1994 東國醫學 Vol.2 No.-

외인성 지방성 폐렴은 1925년 Laughlen에 의하여 처음으로 기술되었으며, 우리나라에서도 소아에서 다수가 보고되었다. 이 지방성 폐렴은 지방성 물질을 흡인 또는 흡입함으로서 쉽게 발생하며 임상적으로 질식, 빈호흡, 호흡곤란, 세균감염의 합병 및 성장 장애 등을 특징으로 한다. 방사선학적 소견으로는 병변의 부위는 환자의 자세와 투약 형태에 따라 드물며 광유 흡인에 의한 경우 종속 위치에서 기름을 비점적 흡인한 경우에 좀 더 광범위하게 분포를 하게되며 가장 잘 침범되는 부위는 우측 폐 하엽의 내측 분절과 심폐 분절 등이고 중력 의존적(gravity-dependent) 침윤에서부터 무기폐에 이르기까지 다양하게 나타난다. 예후는 침범된 병변의 부위, 환자의 전신상태 및 감염의 합병에 따라 다양하며 지방성 폐렴에 대한 특별한 치료가 없기 때문에 예방이 최선의 방법이다. 저자들은 심해 상어 간유 복용후 발생한 지방성 폐렴 2례를 경험하였다. 증례 1은 5개월된 남아로서 입원 당시 흉벽 함몰, 빈호흡을 호소하였고, 흉부 X선 촬영상 양폐야의 침윤을 나타내었고, 약 10개월 후에 실시한 흉부 X선 추적검사에서 병변은 여전히 남아있었다. 증례 2는 15개월된 여아로서 입원당시 잦은 상기도 감염, 발열 및 위식도 역류에 의한 성장 장애를 나타내었고, 흉부 X선 촬영상 양폐야의 침윤을 보였고, 약 9개월 후에 실시한 흉부 X선 추적검사에서 병변은 많이 호전되었다. 저자들은 심해 상어 간유에 의한 지방성 폐렴 2례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Exogenous lipoid pneumonia was first described by Laughlen in 1925 and a few cases of the pneumonia were reported during childhood in our country. It can be easily developed by the aspiration of lipoid substance through the airway. It is characterized by choke, tachypnea, chest retraction, dyspnea, superimposed bacterial infection and growth retardation. Roentgenographically the appearance is very diversed from gravity-dependent infiltration to atelectasis. The prognosis is also diversed according to the degree of involved lision, the general condition of the patients, and the superimposed infections. There's no specific treatment of lipoid peumonia. Therefore, prevention is the most important treatment. We experienced the two cases of exogenous lipoid pneumonia occurred shortly after having several capsules of the deepsea-shark-liveroil(Squalene). In the first case the 5-month-old male infant suffered from chest retraction and tachynea and the patchy and streaky infiltration of the both lung fields on the chest X-ray was revealed at the admission time. About 10 months later the lesion was remained reentgenographically. In the second case the 15-month-old female patient suffered from frequent upper respiratory infections, mild to moderate fever, and failure to thrive probably due to gastroesphageal reflusx. The chest X-ray was similar to the first case, but the lesion is nearly clear about 9 months after the discharge. We report two cases of lipoid pneumonia with brief review of relevant literature.

Is the panoramic mandibular index useful for bone quality evaluation?

Kwon, Ah-Young,Huh, Kyung-Hoe,Yi, Won-Jin,Lee, Sam-Sun,Choi, Soon-Chul,Heo, Min-Suk Korean Academy of Oral and Maxillofacial Radiology 2017 Imaging Science in Dentistry Vol.47 No.2

Purpose: The aim of this study was to determine whether the panoramic mandibular index (PMI) is useful for assessing bone mineral density. We also analyzed the potential correlations between PMI parameters and patient age. Materials and Methods: Four observers measured the PMI of both sides of the mental foramen using a picture archiving and communication system and images in the Digital Imaging and Communications in Medicine format. They studied 300 panoramic radiographic images of patients belonging to the following age groups: 40-49 years, 50-59 years, 60-69 years, 70-79 years, and 80-89 years. The observers were allowed to zoom in or out and to adjust the contrast of the images. Further, they were instructed to record the reasons for any measurements that could not be made. Then, we conducted a reliability analysis of the measured PMI and assessed the correlations between different patient age groups and the 3 parameters used for determining the PMI from the available data. Results: Among the 600 data items collected, 23 items were considered unmeasurable by at least 1 observer for the following 4 reasons: postoperative state, lesion, unidentified mental foramen, and alveolar bone loss. The intraobserver reproducibility of the measurable data was 0.611-0.752. The mandibular cortical width (MCW) decreased significantly as patient age increased. Conclusion: PMI had limited usability when the margin of the mental foramen was not clear. In contrast, MCW, a parameter used for determining the PMI, had fewer drawbacks than the PMI with respect to bone mineral density measurements and exhibited a significant correlation with patient age.
