The purpose of this study was to attempt new starting motion and supply present starting motion in the 500M short track speed skating according to the center of gravity position. The center of gravity position ratio was divided starting motion into five(type A : front 80%-back 20%, type B front 70%-back 30%, type C : front 50%-back 50%, type D : front 30%-back 70%, type E : front 20%-back 80%). The three dimension motion analysis with DLT(direct linear transformation) method was executed using two video cameras. The following conclusion was that It was appear that reaction and execution time in starting motion was the most short in type B. It was characteristic that step of skaters was shorten and center of gravity position ratio was not effect to change of the step in each event. It was appear that the displacement of type D and type E were longer than that type A and type B during the starting motion. It was appear that skill types of center of gravity position ratio to the front were lower than that to the back and contract a posture. Observing the above, it was conclusion that skill type B of center of gravity position ratio to the tent was more effect than that to the back. But it is important that these skill type was most used to the competition and estimate the result.

The purpose of this study was to analyze the loss of open space of schools in Ulaanbaatar city and found out main causes of the conversion trend of open space to suggest alternatives. 76 designated sites were selected from 118 public schools within 6 districts of Ulaanbaatar city. These 76 schools were eligible for analysis of the open space change between 2005 and 2015 with Google Earth Pro. The results showed that $175,048m^2$ open space was developed and two dominant types of open space conversion were found; 1) constructions of school facilities such as soccer field, extended school buildings, parking lot, sidewalk, and square, and 2) constructions of apartment buildings and service facilities such as community center, pedestrian, sports facilities, and parking lot. Apartment complex development has commonly happened in all districts and caused bigger open space loss than other types of development. Chingeltei district is located in the center of Ulaanbaatar city, and schools in this district lost the biggest open space, $50,036m^2$/35.24% over 10 years. The rate of open space loss seemed to be related to the distance from the urban center and open space loss was an ongoing event in Ulaanbaatar city. This trend would not be improved without a strong regulation, so, in this study, making strict regulations that prevent conversions of open space were suggested to conserve open space in Ulaanbaatar city.

Purpose: The purpose of this study was to analyze the possible contributing factors and surgical results of rotator cuff tears in patients younger than 40 years of age. Materials and Methods: From July, 1996 to February, 2000, twelve patients were available to participate in the study. The average age was 35 years (range, 17 to 40 years) old. Follow-up averaged eighteen months (range, 12 to 55 months). There were eleven men and one women. Each shoulder was evaluated with UCLA shoulder functional assessment, return-to-work status, return-to-sport status, and overall postoperative satisfaction. Results: After operation, eleven patients (92%) reported diminished pain relative to their preoperative level, and ten patients (83%) were improved in shoulder function. eleven patients (92%) exhibited improved strength after operation. nine patients (75%) returned to employment, and six patients (50%) returned to sports activities. Preoperative UCLA score averaged 12 and postoperative score averaged 31. Ten patients (83%) were satisfied with the outcome of their treatment. Conclusion: A traumatic event was the etiology of the rotator cuff tears in patients younger than 40 years. Results of surgical treatment in this younger group were satisfactory.

Forty-nine partial thickness rotator cuff tears underwent arthroscopic debridement or repair, and were followed up for a minimum of two years. Follow-up evaluations of the results were completed using a detailed functional questionnaire which was comprised of a rating of the UCLA shoulder scale and return to the previous sports activity and job. The average age of the 49 study patients was 46.5 years(range, 14 to 67 years). The patients were divided into four groups on the basis of the onset of the patient's symptoms. Thirty-five patients(72%) had partial tearing only on the articular surface, six(12%) on the bursal surface, and eight(16%) on both surfaces. Group I consisted of 21 patients with an average age of 56.7. Partial tearing in group I was attributed to the impingement syndrome. In group II, partial tearing of the rotator cuff was related to the anterior instability of the shoulder. This group included 9 patients with an average age of 27.9. In group III, all of the 8 patients were overhead athletes with an average age of 21.8. In this group, no isolated instances of significant trauma were related to the development of the shoulder pain. In group IV, 11 patients noted that a significant traumatic event preceded the onset of their pain. The average age of the patients was 34.9. Overall, 82% of the patients demonstrated satisfactory results and 18% revealed unsatisfactory results. The worst UCLA score and rate of return to the prior activity was noted in group III. In conclusion, partial thickness rotator cuff tear can be caused by subacromial impingement, instability, repetitive microtrauma, and macrotrauma. Arthroscopic debridement of partial tear of the rotator cuff provides a favorable outcome except in overhead athletes.

This study was conducted to investigate the technical factors of Cuervo forward straight vaults with single twist, single and half twists, and double twists actually performed by three execellent male gymnasts participated in artistic gymnastics competition of 2003 summer Universiade in Daegu and the 85th National Sports Festival in Cheongju. To accomplish the research goals the Cuervo vaults of three gymnasts were filmed by using three digital camcorders set by 60 Hz, and data were collected through the DLT method of three dimensional cinematography. The kinematic and kinetic variables as each phasic time, CM displacement velocity, release angle inclination angle hip joint angle landing angle, average horse reaction force average moment arm average torque, whoe body's total remote local angular momentum were analyzed, so the following conclusions were reached. Generally to perform the better Cuervo vault, a gymnast should touch down on the board with the great horizontal velocity of the whole body through the fast run-up, and touch down on the horse by decreasing the horizontal displacement of the whole body during the preflight, so raise CM height gradually within a short horse contact time. He should increase the horse reaction force through checking the horizontal velocity of the whole body effectively and the inclination angular displacement of the handstand, if so he can have the large vertical velocity of the whole body. By using the acquired the velocity and the angular momentum of the whole body, he can vault himself higher and twist sufficiently, then he can get better if the body could be tilted by swinging both arms and perform the cat twist with a little flexions at hip joints. According to the above outcomes we can judge that the best athletes is LuBin, the better is YTY, and the next is JSM.

Intentional draw and fade shots could be good weapons for lowering golf score. But how to make such shots? To investigate deterministic variables generating different projectile paths of shots in square stance was the purpose of this study. Ten right-handed male collegiate athletes, showing 1.3 of averaged handicap, participated in this study. They were asked to intentionally perform three different shots such as the straight shot(control condition), draw shot, and fade shot. Swing path, pelvis rotation angle, thorax rotation angle and left forearm supination angle were determined for dependent variables on impact event at each trial. For statistical analysis one-way repeated measures ANOVA were used. The results showed that swing path was one of main factor making differences among three kind of shots. Straight shot vs. Draw shot, Straight shot vs. Fade shot and Draw shot vs. Fade shot showed differences on swing path. And left forearm supination angle revealed significant difference between draw shot and fade shot, showing a significant larger angle of draw shot than fade shot. No other significant difference was detected for the other variables. We found that the shot characteristics were influenced primarily by swing path and left forearm supination angle.

Background: The purpose of this study was to investigate the effects of physical therapy intervention with local vibration on the physical function of patients with traumatic patella fractures. Methods: This study recruited 6 subjects who had suffered traumatic patella fractures. The study was conducted for an average of 12.8 weeks. Before the treatment (2 weeks post-surgery), they were evaluated using the numeric pain rating scale (NPRS), the Korean-version of the impact of event scale-revised (IES-R-K), pressure pain threshold (PPT), range of motion (ROM) of the knee joint, and the Korean knee injury and osteoarthritis outcome score (K-KOOS) and were reevaluated after 7 and 12 weeks, post-surgery. This study was conducted according to ORIF Patella Fracture Post-Operative Rehabilitation Protocol after applying local vibration. The protocol consists of Phases 1~5 and this study has been applied from phase 2. Results: A comparison of the performance of the participants before and after the intervention showed a decrease in NPRS (9.83±.41→4.83±.98), IES-R-K (68.67±2.73→23.83±2.40), and K-KOOS (Function, Daily living: 70.5±5.96→34.0±3.35, Function, Sports and Recreational activities: 22.83±2.32→10.77±1.37, Quality of Life: 19.33±7.33→7.33±.52) scores. And the ROM (Knee flexion: 30.0±4.47°→128.73±3.6°, Knee extension: -6.83±2.48°→-1.33±1.03°) and PPT (9.67±.52kg/cm²→22.44±2.33kg/cm²) scores increased. Conclusion: These results show that physical intervention with local vibration using a Blackroll® booster and head can help to improve pain, physical function, and psychological status. Also, it was possible to select interventions depending on the patient's condition and the desired goal, using physical intervention with the Blackroll® booster technique.

마라톤은 남녀노소 누구나 즐길 수 있는 대표적인 생활체육으로 자리 잡은 지 오래이다. 최근 삶의 균형을 뜻하는 워라밸(Work and Life Balance) 트렌드가 전 사회로 확대되면서 진입 장벽이 비교적 낮은 마라톤은 20-30대 젊은 층에게 인기를 끌고 있다. 마라톤 대회의 이슈와 연관단어를 분석하여 2030 젊은 층들에게 인기 있는 마라톤 대회의 스포테인먼트적인 요소를 키워드를 통해 분석하여 차별화된 대회를 위한 발전방안을 제시하고자 한다. 키워드 및 연관단어 분석을 위해 네이버(Naver)와 다음(Daum)에서 제공하는 블로그, 카페, 뉴스가 분석채널로 선정되었고, 빅데이터 자료 검색을 위한 키워드는 'JTBC마라톤'과 '문화'를 주제어로 추출하였다. 자료 분석 기간은 2019년 JTBC 마라톤대회 참가 신청이 시작된 2019년 8월 13일부터 2019년 11월 13일까지 3개월간의 기간으로 한정하였다. 자료수집 및 분석을 위하여 소셜 매트릭스 프로그램인 텍스톰(Textom)을 통해 빈도 및 매트릭스 데이터를 추출하였다. 또한 텍스톰을 활용하여 단어들 간의 연결 구조와 연결정도 중심성을 분석하여 관계의 정도를 계량화 하였다. 분석결과를 살펴보면 첫째, 마라톤은 개인 운동임에도 불구하고 젊은 층들은 '러닝'이라는 공통분모를 공유하며 다른 젊은 층들과 '러닝크루'라는 새로운 문화 집단을 형성하였다. 이를 통해 홀로 외로이 뛰며 자신과의 싸움을 벌이는 마라톤의 이미지에서 벗어나 같이 훈련하고 같이 참가하며 같이 즐기는 축제의 장으로써의 마라톤 대회문화가 형성된 것을 확인할 수 있었다. 둘째, '훈련'의 과정을 중시하고 이를 다른 이들과 SNS를 통해 공유하는 문화가 확산되었음을 알 수 있었다. 세 번째, 유명인과 관련된 단어가 다양하게 도출되었다. 이는 마라톤대회에 참가하여 함께 레이스를 펼친 유명인은 물론 대회가 끝난 후 '애프터공연'에 출연하는 연예인에 대한 참가자들의 높은 관심을 반영한 결과라 하겠다. 네 번째, '후기'와 관련된 단어가 빈번히 도출되었다. 이는 젊은 마라토너들이 마라톤 준비과정은 물론 대회 당일의 경험을 타인들과 공유하는 문화가 반영된 것이라 분석된다. 다섯 번째, 공연과 관련된 단어가 상위 순위에서 도출되었다. 여섯 번째, '도전', '멋진', '성공', '즐겁' 등 긍정적이고 진취적인 감정을 표현하는 단어가 다수 도출되었다. 이 연구의 결과를 통해 젊은 아마추어 마라토너들의 마라톤대회 참가 동기와 목적은 건강과 체력증진처럼 단일하거나 단편적이지 않으며 다양하고 복합적인 종합 문화체험 행사로 마라톤 대회에 참가하고 있음을 확인할 수 있었다. 결국, 젊은 마라토너들의 마라톤 참여는 참가자체에 목적을 두는 '체력증진'의 목적보다는 대회를 선정하고 대회를 크루멤버들과 함께 준비하고 대회를 끝맺음하기까지의 일련의 과정을 하나의 '축제'로 여기는 것을 엿볼 수 있었다.
