      • 거대 긴장성 낭종으로 내원한 폐 Langerhans 세포 조직주증

        양석철,손장원,윤호주,신동호,박성수,함시영,장세진,박용욱 한양대학교 의과대학 2000 한양의대 학술지 Vol.20 No.1

        Pulmonary Langerhans cell histiocytosis is a hetergenous group of conditions of unknown etiology characterized by an abnormal proliferation of antigen presenting cell of bone marrow derivation known as Langerhans cells that invade and destroy distal bronchioles. The outcome is highly variable, ranging from rapid spontaneous resolution to irreversible respiratory failure. We describe a patient with biopsy-confirmed pulmonary Langerhans cell histiocytosis who presented with large tension cyst, treated with pneumothorax tube with Heimlich flutter valve.

      • 정맥내 통증자가조절법을 이용한 Nalbuphine-Ketorolac과 Butorphanol-Ketorolac의 술후 진통효과 비교

        윤석화,이원형,손수창,신용섭,김윤희,양신영 충남대학교 의과대학 의학연구소 2003 충남의대잡지 Vol.30 No.1

        This study aimed to compare analgegic efficacy, satisfaction score and side effect of nalbuphine-ketorolac and butorphanol-ketorolac by using intravenous patient controlled analgesia(IV-PCA) for postoperative anlgesia following a gastrectomy for stomach cancer. Ninety patients who had undergone gastrectomy for stomach cancer under general anesthesia were randomly divided into two groups. Each group recieived nalbuphine 50mg with ketorolac 150mg(Group 1, n=45) and butorphanol 5mg with ketorolac 150mg(Group 2, n=45) by using IV-PCA during postoperative 48hrs. Assessments for pain with numerical rating scale(NRS), and side effects were evaluated at 2hr, 6hr, 12hr, 24hr, 36hr and 48hr after the operation. There were no significant difference in NRS for pain during rest, but Group 2 requested significantly greater amount of supplementary diclofenac during first 24 hours. Side effects were higher Group 1 in pruritus, nausea and vomiting and Group 2 in sedation, nausea and vomiting. This study suggests that adding ketorolac with intravenous nalbuphine or butrophanol in using an intravenous PCA can decrease analgesics requirement and improve analgesic property without the major morbidity like respiratory depression, but needs for the careful observation and treatment on the side effects like nausea. vomiting, pruritis and sedation...

      • 매트운동에서 핸드스프링 앞수완동작의 운동학적분석

        권오석,윤양진 釜山大學校 附設 體育科學硏究所 2002 體育科學硏究所 論文集 Vol.18 No.1

        In this study, 4 gymnasts who were students of B University at the same time was taken and their performance of forward Handspring salto with body stretched was looked at through 3 dimensional of the body, the tract of moving and its kinematic element. It is all to provide basis data for efficient training of gymnasts and the findings are as follows: 1. From the examination of the sequence of duration phase, it appeared that in phase 1, the superior group had longer duration with long strider in home step, in phase 2, they bent their upper body making big shoulder angle and changed the straight-line motion to circular motion. And it appeared to result in efficient circular motion while in flight phase of 4 and 5. 2. It appeared that in the event 2 in which the movement of support with hands took place, the Superior group had bigger shoulder angle so that the Handspring movement was faster in its rotation on the axis of hands supporting. In event 3 of jump in feet, the hips angle was big enough to produce with its weight sufficient pressure on feet to maximize the reaction of the floor. 3. For the speed in each phase, the Superior group spurred rapid speed with the hips angle curved a little bit in event 4 in which the body made vertical angle to the floor while in handspring salto forward piked movement of the body and in event 5, the hips angle extended rapidly producing good rotation speed. In summery of all the elements considered above, big strider with the body bent to produce decisive support on the hands seemed to result in increased rotation speed in handspring, bigger pressure on feet, and good speed in handspring salto forward stretched.

        핸드스프링 몸펴 앞공중1회 비틀기 동작의 소요시간 및 각운동량 분석

        권오석,윤양진,서국웅 한국운동역학회 2002 한국운동역학회지 Vol.12 No.2

        남자 기계체조 국가대표 선수 3명과 대학선수 3명을 대상으로 핸드스프링 몸펴 앞공중1회 비틀기 동작을 구간 및 국면별로 분석하고 동작의 숙련도에 따라 역학적 변인이 집단 간 어떠한 차이를 보이는지를 구명하기 위하여 Kwon3D 프로그램을 활용하여 분석한 결과 다음과 같은 결론을 얻었다. 시간요인에서 보폭을 크게 딛는 것이 손을 빠르게 지지 할 수 있고, 핸드스프링 체공시간은 짧게 하여야 발구르기의 압력을 높여 비틀기동작에서 체공 소요 시간이 길어지므로 비틀기 수행의 완성도를 높일 수 있는 것으로 나타났다. 각운동량 요인에서 기술수행 시 전체적으로 좌우(X)축에 대한 각운동량이 전후(Y)축과 수직(Z)축에 대한 각운동량에 비해 더 큰 값을 보였다. 좌우 축 각운동량은 지면에서 이지되어 동작을 수행하는 핸드스프링회전과 앞공중1회 비틀기에서 숙련자가 상대적으로 더 큰 각운동량 보이는 것으로 나타났다. The purpose of this study were a two-fold: ⑴ to analyze event and phase of handspring salto forward stretched with turn; ⑵ to know the differences in the kinematic variables between two groups. A Kwon3D program served for the estimation of this study. The group was divided into three National representative and three well-trained calisthenics in this study. The results of this study revealed that ⑴ the forward somersault performance was increased when duration time in the air was long during the salto forward stretched that the duration time of Handspring is short, the pressure at takeoff is high, the stride is large, and hands are supporting on the ground quickly; ⑵ comparing the angular movement of anterior and posterior y axis and vertical z axis, the angular movement of right and left x axis was higher during the performance. As a result, the national representative players showed better performance in Handspring salto forward stretched with turn.

        핸드스프링 무릎굽혀 앞공중돌기동작과 몸펴 앞공중돌기동작의 운동학적 비교분석

        권오석,윤양진 부산대학교 사범대학 2002 교사교육연구 Vol.41 No.-

        In this study, 4 gymnasts who were students of B University at that time were taken and their performance of handspring salto forward tucked and handspring salto forward stretched at through 3 dimensional movement analysis to tell the duration for each phase of the movement, the movement of the articulation of the body, the tract of moving center of the body, and its kinematic element. It is all to provide basic data for efficient training of gymnasts and the findings are as follows: 1. The time duration for phase 1 and 2 differed each other and faster landing on hands in forward handspring salto forward stretched than in forward salto with the body bent helped the straight-line movement change to circular movement giving the handspring a big circular movement, and forward jumping on feet with rapid upright of the upper body maximized the circular radius on the axis of the jaw, contributing to rapid backward circular movement of the lower part of the body. 2. In the observation of the position of the body center, the sway of the body center and the power dispersion was smaller in general in forward salto with the body stretched than in forward salto with the body bent. And in its forward and backward position, it showed lower position in handspring phase of 1 and 2, but higher in the salto of phase 3, 4 and all these contributed to bigger and more stable circular motion. 3. Articulation angle of the body in each phase of handspring forward salto with the body bent and in forward salto with the body stretched appeared to be different through 5 phases. It had more centripetal force in forward salto with the Elbows, shoulders, hips, knees having more curve. In forward salto with the body stretched, centrifugal force appeared to be strong with the elbows, shoulders, hips, knees all being extended. To summarize, Handspring forward salto with the body bent seems to have curved articulation and be slow, while in forward salto with the body stretched, its circular movement appeared be faster with speedy landing on hands, extended knees angle for good jump, and with accelerated hips articulation. Handspring forward salto with the body stretched appeared to enhance its technical performance with far-reaching circular motion. Therefore, forward salto with the body stretched is considered to produce more gracious and dynamic motion than forward salto with the body bent does.
