Purpose: To investigate the arthroscopic findings, and to evaluate the clinical outcomes of the treatment of posterior internal impingement of the shoulder in baseball players. Materials and Methods: We followed up 5 cases who were diagnosed as posterior internal impingement for the mean 15 months. All of the cases complained of the pain in the posterior shoulder at late cocking, and were positive in the relocation test added by hyper-horizontal abduction at $120^{\circ}$ abduction of the arm. We sutured posterior labral tear and SLAP lesion arthroscopically, and conducted debridement for rotator cuff. Three cases were performed of anterior capsular plication and the other two were performed of thermal capsular shrinkage. Pain, range of motion, and level of return to sports activity were assessed for the results. Results: As to the arthroscopic findings, all the five cases showed the fraying in posterosuperior labrum, and two of them was accompanied with the flap tear in posterosuperior labrum and the other one was accompanied with type 2 SLAP lesion. All the cases showed the fraying in supraspinatus, and one case showed partial tear. Meanwhile, in all the cases, the rotator cuff was impinged to the labrum at $90^{\circ}{\sim}120^{\circ}$ of abduction and external rotation. As to the postoperative results, all the cases did not complain of pain or instability while pitching, and the competition was recovered to be the mean 88%($80{\sim}100%$) of that before the injury. Conclusion: Definite diagnosis for the posterior internal impingement would be possible through arthroscopic examination. Favorable outcomes could be obtained with capsular plication or shrinkage for anterior microinstability and stretching exercise for posterior capsule tightness inducing the internal impingement.

Purpose: The purpose of this study is to evaluate the clinical results for the treatment of osteoarthritis of the knee by arthroscopic procedure according to presence or absence of mechanical symptoms. Materials and Methods: We studied sixty patients (60 knees) who underwent arthroscopic procedure for the treatment of osteoarthritis of the knee from October,2000 to January,2002. The average follow up period was 15 months(12-30 months). We evaluated the mechanical symptoms by simple radiographs, history taking and physical examination. We analysed the clinical results by Baumgaertner's scale. Results: The Baumgaetner's score improved from 3.1 preoperatively to 8.1 postoperatively in the group with mechanical symptoms, whereas the scores in the group without mechanical symptom improved from 3.5 preoperatively to 5.4 postoperatively. The patients with mechanical symptoms were satisfied more than the patients without mechanical symptoms. Conclusion: The arthroscopic surgery could be one of good alternative treatment methods for the osteoarthritis of the knee with mechanical symptoms . But, more than these patients will be needed for further evaluation.

Purpose: All-inside meniscal repair using FasT-Fix (Smith & Nephew Endoscopy, Andover, Massachusetts, USA) is a popular method for the meniscal tear. However, there was no report after all-inside repair using FasT-Fix for the meniscal tear in Korea. Therefore, the purpose of this retrospective study was to report clinical outcomes after all-inside meniscal repair using FasT-Fix. Materials and Methods: 25 consecutive patients underwent meniscal repairs using FasT-Fix for tears of the posterior horn of the medial or lateral menisci combined with hamstring anterior cruciate ligament (ACL) reconstructions. Postoperative evaluations included Lysholm knee score and Tegner activity scale. Using clinical criteria, a repaired meniscus was considered healed if there was no effusion or joint line tenderness, negative McMurray test, and no sense of giving way. Results: The average follow-up was 47.9 months (range, 40 to 61 months). At follow-up, the mean Lysholm score was 91.8 and the mean Tegner activity scale was 5.6. According to clinical criteria, 20 (80%) menisci was healed, and 5 (20%) failed. Conclusion: All-inside meniscal repair using FasT-Fix showed satisfactory results in patients with hamstring ACL reconstructions.

The purpose of study was to evaluate the economic evaluation of Chuncheon curling stadium. In oder to estimate economic evaluation, benefit/cost ratio, net present value and internal rate of return were used. Additionally, in order to investigate the socio-economic spread effect, literature review and input-output analysis were used. The results of study were as follows. First, as a result of analyzing the demand for curling stadiums in Chuncheon, it was believed that the construction of the stadium will attract athletes from the Chuncheon region as well as athletes from Seoul, Incheon, Gyeonggi Province and North Chungcheong Province. Second, economic validity analysis showed that the initial investment did not make sense, but the players' training and competitions and the advantages of the potential experience of curling events for citizens in nearby areas, including Chuncheon, make the construction and operation reasonable. Third, as a result of the review of the social and policy validity of the curling stadium, the project to build a curling stadium in Chuncheon was secured with a policy validity as a public sports facility necessary for both professional and living athletes. Finally, the analysis of socio-economic spread effect of curling stadiums had shown that it would have a positive effect on the level of satisfaction of the general public as well as the discovery of elite athletes.

Anthropometry has been broadly explored in various fields including automobile industry, home electronic appliances, medical appliances and sports goods with aiming at reaching satisfaction to consumer's need and efficiency. However, current technologies to measure a human body still have barriers in which the methods mostly seem to be contingent on expensive devices such as scanner and digital measuring instruments and to be directly touchable to the body when obtaining body size.. Therefore, in this paper, we present a general method to automatically extract size of body from a real body image acquired from a camera and to utilize it into recommend systems including clothing and bicycle fitting. At first, Haar-like features and AdaBoost algorithm are employed to detect body position. Then features of body can be recognized using AAM. Finally clothing and bicycle recommending modules have been implemented and experimented to validate the proposed method.
