        구술사를 통한 아프리카 대륙에서 태권도의 진출과 확산 - 코트디부아르 김영태 사범의 구술사를 중심으로-

        김상천 ( Sang Cheon Kim ) 한국체육사학회 2014 체육사학회지 Vol.19 No.3

        본 연구는 아프리카 대륙의 태권도 진출과 확산에 관한 연구로 코트디부아르의 김영태사범의 면담내용을 중심으로 연구한 결과 다음과 같은 결론을 도출하였다. 첫째, 코트디부아르에 가라데와 유도가 이미 선점하고 있는 어려운 상황에서 김영태 사범의 노력으로 태권도의 우수성을 인정받아 코트디부아르 태권도 협회를 창설하였다. 둘째, 코트디부아르는 김영태 사범의 지도하에 각종 세계태권도대회에서 두각을 나타내었다. 그리고 아프리카 태권도연맹 창설과 제1회 아프리카 태권도대회를 코트디부아르의 아비장에서 개최 하였다. 셋째, 코트디부아르는 태권도가 보급된 지 20년 만에 하향곡선을 타고 있었다. 그 이유는 전 세계에서 태권도를 배우는 나라들이 늘어나 전체적으로 실력이 평준화 되었고 신체적인 조건면에서도 불리하게 작용했기 때문이다. The purpose of this study was to examine the entry and spread of taekwondo in Africa. After taekwondo instructor Kim Young-tae who worked in Cote d``Ivoire was interviewed, the interview data were analyzed. The findings of the study were as follows: First, karate and judo were already popular in this region. Under the harsh circumstances, the excellency of taekwondo was acknowledged owing to the endeavor of instructor Kim, and the Cote d``Ivoire Taekwondo Association was established. Second, this country stood out among different nations in all sorts of worldwide taekwondo competitions thanks to instructor Kim``s guidance. The African Taekwondo Union was founded in Abidian, one of the largest cities in this country, and this city hosted the 1st African Taekwondo Championship as well. Third, taekwondo was on the wane 20 years after it was introduced in this country. The reason was that an increase in the number of countries in which taekwondo was practiced was followed by the equalization of taekwondo skills, and the disadvantageous physical conditions of its people was another reason.

        Original Articles : Clinical significance of occult hepatitis B virus infection in chronic hepatitis C patients

        ( Jae Young Jang ),( Soung Won Jeong ),( Sung Ran Cheon1 ),( Sae Hwan Lee1 ),( Sang Gyune Kim ),( Young Koog Cheon ),( Young Seok Kim1 ),( Young Deok Cho1 ),( Hong Soo Kim ),( So Young Jin ),( Yun Soo 대한간학회 2011 Clinical and Molecular Hepatology(대한간학회지) Vol.17 No.3

        Background/Aims: We investigated the frequency of occult hepatitis B virus (HBV) infection in anti-hepatitis C virus (HCV)-positive individuals and the effects of occult HBV infection on the severity of liver disease. Methods: Seventy-one hepatitis B virus surface-antigen (HBsAg)-negative patients were divided according to their HBV serological status into groups A (anti-HBc positive, anti-HBs negative; n=18), B (anti-HBc positive, anti-HBs positive; n=34), and C (anti-HBc negative, anti-HBs positive/negative; n=19), and by anti-HCV positivity (anti-HCV positive; n=32 vs. anti-HCV negative; n=39). Liver biopsy samples were taken, and HBV DNA was quantified by real-time PCR. Results: Intrahepatic HBV DNA was detected in 32.4% (23/71) of the entire cohort, and HBV DNA levels were invariably low in the different groups. Occult HBV infection was detected more frequently in the anti-HBc-positive patients. Intrahepatic HBV DNA was detected in 28.1% (9/32) of the anti-HCV-positive and 35.9% (14/39) of the anti-HCV-negative subjects. The HCV genotype did not affect the detection rate of intrahepatic HBV DNA. In anti-HCV-positive cases, occult HBV infection did not affect liver disease severity. Conclusions: Low levels of intrahepatic HBV DNA were detected frequently in both HBsAg-negative and anti-HCV-positive cases. However, the frequency of occult HBV infection was not affected by the presence of hepatitis C, and occult HBV infection did not have a significant effect on the disease severity of hepatitis C.

      • 中世 體育이 지닌 現代的 意味 : 유럽地域의 各 階層別 中心으로

        金相洪,李淳川,裵永相 啓明大學校 生活科學硏究所 1986 科學論集 Vol.12 No.-

        This study was conducted to research into the gymnastic circumstances according to medieval thought and its classified classes. The results of medieval physical education and their contributions to us on the basis of characteristics of their classes and their physical activity are as follows: 1. The gymnastics development of the Middle Ages was hindered by Christian view on physical culture. 2. The aristocratic view on gymnastics was changed into equalitarian by the birth of Christianity. 3. The physical education of Knight was actual military training in the early age and a formal one in later age, moralism was introduced into physical education through knighthood. 4. The medieval gymnastics activities avoided by knight, chmchemn, and aristocracy were highly popular among guidsmen, bourgeois and the peasantry as a recreation like ball-game and dancing. This was developed into modern gymnastic tendency. 5. The medieval gymnastics which was called dark age of physical education owing to the gymnastics view of Stoic asceticism was advanced through the middle of medieval era to ward the modern form of sportmanship in later age.

      • 상업스포츠 참가자의 사회경제적 배경과 사회관계 만족 및 관계지속의사의 관계

        김경식,장현철,윤상영,천정필 한국스포츠리서치 2004 한국 스포츠 리서치 Vol.15 No.3

        This study was to analysis a relationship between socio-economic characteristics, social relation satisfaction, and the adherence of social relation at the commercial sports centers. To attain the goal of the study described above paragraphs, some members of commercial sports center held in Seoul were set as a collected group. Then, using the cluster random sampling method, finally drew out and analyzed 713 people in total The material collection device was the brochure named <the survey on socio-economic characteristics, social relation satisfaction, and the adherence of social relation at the commercial sports centers>. The result of reliability check up was here below; social interaction, Chronbach' α=.840~.915, the satisfaction according to social relation, α=.787, the adherence of social relation α=.847. To analyze materials, factor analysis, reliability analysis, oneway-ANOVA, multiple-regression were used as statistic analysis techniques. The conclusion based on above study method and the result of material analysis are here below. First, it is found that there is a significant difference in satisfaction according to social relation. Second, it is found that there is a significant difference in the adherence of social relation. Third, the satisfaction according to social relation influences on the adherence of social relation.

        니켈촉매를 이용한 메탄의 부분산화에 의한 합성가스 제조

        김상범,신기석,박은석,곽윤철,천한진,함현식 한국화학공학회 2003 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.41 No.1

        메탄의 부분산화에 의하여 힙성가스를 제조하였다. 촉매는 니켈 담지 촉매를 사용하였으며, 담지된 니켈의 양은 10-15 wt%이었다. 담체로는 BaO, CaO, MgO를 사용하였다. 촉매는 함침법으로 제조하였으며, 반응은 CH_4:O_2의 비가 2:1, 1 atm, 750℃에서 수행하였다. 반응결과, MgO를 담체로 사용하였을때 가장 좋은 촉매활성을 보여주었으며, 니켈의 담지량이 13 wt%일때 촉매의 활성이 가장 좋았다. 이 13 wt% Ni/MgO 촉매의 경우 80%의 메탄 전화율과 93% 및 94%의 CO 및 H_2 선택도를 각각 얻을 수 있었다. 또한 이 촘매는 약 180시간 정도의 반응 후에도 촉매의 활성이 감소하지 않았다. 논란 중인 반을 기구에 대하여 조사해 보기 위하여 펄스방식으로 반응물을 투입하며 촉매 상 · 하층의 온도를 측정하였고, 반응시간에 따른 반응물과 생성물의 몰수 변화, 그리고 O_2-TPD 실험을 수행하였다. 그 결과 메탄으로부터 합성가스가 생성되는 경로는 2단계반응으로써 메탄이 완전 산화되어 CO_2와 H_2O가 생성되고, 이 생성된 CO_2 및 H_2O가 미반응 메탄과 각각 개질반응을 하여 합성가스가 생성됨을 알 수 있었다. Synthesis gas producution by partial oxidation of methane has been investigated using BaO, CaO and MgO supported Ni catalysts. The catalysts were prepared by the impregnation method. The reaction was carried out at I atm, 750℃, and CH_4:O_2=2:1. The highest catalytic activity was obtained with MgO support when Ni loading was 13 wt%. With the 13 wt% Ni/MgO catalyst, methane conversion was 80%, and CO and H_2 selectivities were 93% and 94%, respectively. The activity of the catalyst remained nearly constant after 180h of the reaction. To investigate the reaction mechanism of this reaction, the temperature of the actalyst bed at top and products were determined with time; and O_2-TPD experiment was carried out. From the results, it is deduced that the reaction takes place by a two-step reaction-first, total oxidation of methane to CO_2 and H_2O takes place, and then the produced CO_2 and H_2O are further reacted with CH_4 to give synthesis gas.

      • 결과지식후 지역간격중 간삽활동이 운동학습에 미치는 영향

        김승철,전상돈 成均館大學校 科學技術硏究所 1992 論文集 Vol.43 No.2

        Information presented from an external source to a learner following a practice response is commonly knowledge of result(KR). The importance of KR can be demonstrated by observing the influence on learning of activity conditions following the receipt of KR during the post-KR interval. The thirty-three subject were random assigned to one of three post-KR interval activity condition (n=11). The 'no-activity' condition involved an empty 10-sec post-KR interval. The 'two-related activity condition required each subject to practice the same patten of movement of the 40cm criterion and then at a 20cm criterion. The 'non-related activity' condition required verval task during 10-sec post-KR interval. The result of experiment provided evidence that post-KR activity conditions did not influence learning a skill.
