        Steeper한 base curve를 갖는 안경렌즈 설계

        이수천 대한시과학회 2015 대한시과학회지 학술대회 Vol.2015 No.10

        본 논문은 +4.00D의 구면 굴절력을 사용하여 같은 굴절력을 갖는 두 형태의 볼록 메니스 커스 형태의 렌즈 중 렌즈의 curve가 더 steeper한 Wollaston 형태의 렌즈를 설계하여 눈의 모형안과 함께 최적화 과정을 통해 설계하였다. 사용한 렌즈 재질의 굴절률은 1.523이고 아베 수는 58.9이다. 안경렌즈의 직경을 50mm로 하고 구한 중심 두께는 3.4mm이다. 이렇게 설계 하여 얻은 렌즈의 유효굴절력은 +4.70D, back vertex power는 +4.92D 그리고 front vertex power는 +4.54D이다. 또한 제 1 주점은 1면으로부터 –1cm 위치에 있고, 제 2 주점은 2면으 로부터 –0.7cm에 위치해 있다. 또한 설계한 렌즈로부터 구한 image surface의 곡률반경은 – 309mm이고 far point sphere의 곡률반경 값은 –176mm이다 이로부터 나타낸 power error를 그림 1에 나타내었다. 그리고 종 색수차 값은 0.07D 값을 보였다. 설계한 렌즈의 수차를 알아 보고, 성능 평가는 회절광학적인 MTF를 계산하여 알아보았으며 그 값은 10lp/mm의 공간주파 수에서 대략 70% 정도 값을 보였다. 이를 통하여 flat한 base curve를 갖는 경우보다 steeper한 base curve를 가질 때 더 선명한 시야뿐만 아니라 더 넓은 시야를 가질 수 있음을 비교해 볼 수 있었다.

        타우린 섭취와 운동훈련이 고지방식이 흰쥐의 글리코겐 저장량 및 항산화 활성의 변화에 미치는 영향

        이수천,김해헌,류승필 한국운동영양학회 2004 Physical Activity and Nutrition (Phys Act Nutr) Vol.8 No.2

        Taurine (2-aminoethane sulfonic acid), a nonprotein amino acid, has hypolipidemic, antiatherosclerotic, and antioxidative effects. In this point of view, twenty-one male Sprague-Dawley rats were used as the subjects. They have fed 40% of high fat diet with or without 15 g/kg of taurine. In addition, they exercise on the treadmill at 27 m/m, 8% of incline for 4 wks. Stored glycogen contents in liver and skeletal muscles were analyzed. In addition. SOD activity and MDA concentration in liver were analyzed. Liver and gastrocnernius muscle glycogen content were significantly increased in taurine supplemented group (p<.05). MDA was significantly decreased in taurine supplemented group (p<.05). And SOD was significantly increased in exercise and taurine supplemented group (p<.05). These results suggested that taurine supplementation before exercise might prevent exercise induced lipid peroxidation and enhance glycogen storage, which might increase exercise performance.

        탈진운동 후 (-)-Hydroxycitrate 섭취가 저장글리코겐회복능에 미치는 영향

        이수천,임창수,장응찬,임기원,윤신중,류승필 한국운동영양학회 2003 Physical Activity and Nutrition (Phys Act Nutr) Vol.7 No.2

        Hydroxycitric acid (HCA) is not interfere fat oxidation during moderate intensity exercise and reduce fat accumulation in the body. Depleted glycogen by exhausted exercise caused fatigue that reduced exercise performance in the continuos day or match. lf considering the effect of HCA, even so, ingestion after exhaustive exercise. Therefore, 500 mg of HCA was intubated to the Sprague-Dawley male rats that have exercise trained for 3-week and exercise on the treadmill until exhaustive. Liver and muscle (soleus, gastrocnemius and quadriceps) glycogen and blood glucose, lactate, and FFA were analyzed. Glycogen contents were reduced after exhaustive exercise then increased 24-h of recovery periods without HCA effect. Blood profiles were not affected by HCA either. These result suggested that HCA effect was showed only during exercise in rats.

      • 씨름競技에 있어서 重心點 移動이 勝敗에 미치는 影響(Ⅱ) : 高等部 中心으로

        李秀川 영남이공대학 1982 論文集 Vol.11 No.-

        The purpose of this paper is to analyze how much the transference of the gravity effects wins or defeats in the Ssireum Gaines. Generally, persons are keeping the balance according to the physical and if one were to receive force from external, on the size of the force he falls down to break the balance. This fact of the falling down proves transfering of the graving on account of external force. After considering the importance and principle of the Ssireum Games in the study, I try to analyze the facts to influence wins or defeats in the Games. The result are as follow: 1) In movement inclination, the left leg was more often used as the upholding leg and the rotating direction than the right one was. It was certain, from the rotation comparism in accordance with the left and right direction one received the force from the opponet by stastistics, that to rotate rightward is faster than leftward. 2) judging from a result of measurement and analysis about the graving transference direction in the attacks, it was acknowleded that persons were apt to preponderate the rotation, when transfered from the top to the under, from the back to the front, from the right to the left, and that the rate of win was higher than defeat. 3) As a result of 1) and 2), I come to an apparent conclusion in this paper, that is to say the rate of success in Ssireum Games was hiher than that of loss when rotating the gravity from the right to the left the center of gravity was transferred from the back to the front, the under to the top.

        아동의 임파워먼트가 행복감에 미치는 영향: 지역아동센터를 중심으로

        이수천,박진희,조미애,최윤석 한국학교사회복지학회 2013 학교사회복지 Vol.- No.25

        This study explores the empowerment factors which affect the subjective well-bing of some 291 community child center children, aged between 7 to 15 years old. The subjects of the study were selected from 16 community child centers located in Seoul and Gyeonggi province. The major findings were as follows. First, the intrapersonal empowerment affects the subjective well-being by simple regression analysis. Second, the interpersonal empowerment affects the well-bing by simple regression analysis. Third, the self-esteem, the user satisfaction in community child center use, and the intrapersonal empowerment except the interpersonal empowerment affect the subjective well-being by multiple regression analysis. Based on these results, the following conclusions are suggested. It is necessary to pay attention on the empowerment, specially on the intrapersonal empowerment, in order to increase the subjective well-bing of the community child center children. And it is necessary to provide programs promoted empowerment. 행복추구는 인간의 기본적 권리로서 이는 아동에게도 동일하게 적용되는 것이다. 아동의 행복은 헌법과 아동복지법 등에서 권리로 천명되고 있지만 이에 대한 실증적인 연구는 많이 드러나지 않고 있다. 임파워먼트는 아동이 가지고 있는 강점 및 자원을 충분히 활용하는 것을 이른다. 특히 관련연구들을 통하여 아동에게 있어 임파워먼트는 행복감에 영향을 미치는 요인임을 추정할 수 있다. 아동의 임파워먼트가 행복감에 영향을 미치는 것이 밝혀지면 사회복지실천에 있어 아동의 행복을 위한 구체적인 논의들을 이어갈 수 있다. 따라서 본 연구는 이를 실증적으로 밝히기 위하여 서울, 경기 지역 16개 지역아동센터에서 7세부터 15세까지 291명의 아동을 대상으로 임파워먼트와 행복감의 영향관계를 살펴보았다. 연구결과, 먼저 개인내적 임파워먼트는 행복감에 영향을 미치는 요인으로 나타났으며 대인관계 임파워먼트 역시 행복감에 영향을 미치는 요인으로 나타났다. 그런데 다른 변인들과 함께 영향관계를 파악하기 위하여 위계적 회귀분석을 한 결과 자아존중감, 지역아동센터만족도, 개인내적 임파워먼트는 아동의 행복감에 영향을 미쳤으나 대인관계 임파워먼트는 영향을 미치지 않는 것으로 나타났다. 대인관계 임파워먼트의 영향력이 다른 요인들에 의하여 상쇄되었음을 보여준다. 영향력의 크기는 자아존중감, 지역아동센터만족도, 개인내적 임파워먼트 순이었다. 연구 결과에 따라 아동의 행복을 증진시키기 위하여 특히 아동이 가지고 있는 강점 및 자원인 임파워먼트를 강화시키는 것이 필요함을 제언하였다.

      • 씨름 選手들의 스포츠 傷害에 관한 硏究

        李秀川,權泰東 慶北大學校 師範大學 體育學硏究會 1988 體育學會誌 Vol.16 No.-

        This study was aimed at investigating the injury of Ssireum athletes. The Subjects employed were a 909 Ssireum athletes. To put the subjects concretely premary school students were 246, middle school were 261, high school were 305 and college and general athletes were 246, The result obtained about physical site of injury, injury ocurred season, necessary period in remedy and ways of treats are summarized as follows. 1. In view of physical site of injury, knee joint injury was 28%, vertebra injury was 22% and ankle joint 21% of all. 2. In view of injury occurred season, the case of injury occurred in winter was 37.7% and next was the case of injury occurred in spring as 28.8%. 3. Necessary period in remedy was generally appeared 2∼3 months in the injury of ankle joint, knee joint and vertebra. The other injury generally needed within 1 month in remedy. 4. Ways of treats were different in accordance with the Physical site of injury. But knee joint injury mostly relyed upon physical therapy and vertebra and ankle joint injury geneally relyed upon chinese medicine.
