윤재만 한국운동역학회 1998 한국운동역학회지 Vol.8 No.2

The major kinematical variables acting upon shooting motion can be described as follows; foot touch point coordination , each shooting movement time, ball velocity angular change of lower limbs segment. The analysis of the above variables presents the following findings: Instep and infront of the ball and the touch foot from the left and right position was significantly different from these of inside. There was stability from the inside position. In terms of the time required for each shooting motion, there was an average of 38.6±18.2 m/sec in TSP stage and 66.8±9.7 m/sec in SSP stage. Maximal velocity showed the mean 24.60±1.45 m/sec. No difference was shown among different types of shooting. Shank segment angle descended toward the minus angle from X direction. However, after knee joint maximal flexion the angle became bigger and before and after the impact, it changed into the plus angle. There was no marked difference between instep and infront at the left foot touch time. At the foot touch time in shank segment angular velocity, instep and infront indicated-227.54±217.36 deg/sec showing the minus rotation and inside showed 46.05±261.59 deg/sec. There shooting in swing leg knee maximal flexion displayed the plus angular velocity and the angular velocity of inside shooting increased significantly compared with other two shooting.

윤재만 한국운동역학회 2000 한국운동역학회지 Vol.9 No.2

The major biomechanical variables acting upon kick motion can be described as follows; reaction force and impulse force, joint force moment. The analysis of the above variables presents the following findings. 1. The maximal value to vertical reaction force was 1431.4±310.9N on the average. The value of instep and infront kick was much larger than that of inside kicks. The force to prevent body movement and to accelerate swing leg rotation accounts for this difference. The average impulse force of the vertical direction was 5720.4±1964N · S indicating the instep kick was mort significant than the other two kicks. This means that inside kick shows a small numerical value in vertical direction velocity change. 2. Dorsi flexion/plantar flexion moment in the right ankle joint from a kicking position in comparison with knee and hip joint, flexion/extension moment showed a form similar to a slow parable shape. The maximal flexion moment emerged when the right foot was off and the impact was in the range of 40-60%

Hemifacial microsomia is a common congenital craniofacial deformity involving bone and soft-tissue. Mandibular hypoplasia is the most obvious skeletal manifestation of hemifacial microsomia. In the past, complete realignment of the skeleton was preferred to soft-tissue correction, which was clearly second choice. However, in this study, simultaneous correction of bone and soft tissue deformities were equally important in treatment of hemifacial microsomia. One-stage and simultaneous bone and soft tissue reconstruction is possible and staged operations of the skeleton and soft tissue are no longer necessary, except in special cases. Even in children and adolescents, good results and normal growth potential can be achieved with simultaneous correction of bone and soft tissue.

오만택,오재화,윤향석 圓光大學校 醫科學硏究所 1999 圓光醫科學 Vol.15 No.2

Background: We tried to occlude the duct with retrievable coil device(Duct-Occlud) in 6 children with patent ductus arteriosus(PDA). And, we reviewed the technical aspects and the short-term results. Methods: PDA occlusion with "Duct-Occlud" system was attempted in 6 patients with small to moderate size PDA from January 1999 to November 1999. Mean age of the patients was 6.56 (1.33 to 14)year. After estimation of the size of PDA, retrievable coil device(Duct-Occlud) was inserted through the femoral vein route. The angiocardiography was performed 10 minutes after the procedure. On next day and one week later, the follow-up echocardiogaphy was checked. And then, it repeated at 3 months, 6 months later. The follow-up duration was 5.5(1 to 11) months. Results: The Qp/Qs was 1.44(1.25 to 1.63), Rp/Rs 0.09(0.03 to 0.15), size of pulmonary end 2.73(2.1 to 3.5)㎜, aortic end 4.58(2.8 to 5.5)㎜, length 5.83(3.8 to 8)㎜. The complication of the procedure occurred in one patient by uneventful earlier detatchment. Flow disturbance was not developed. Conclusions: Coil occlusion with the Duct-Occlud system is a safe and effective method for percutaneous closure of small to moderate-size PDAs. Larger numbers of treated patients and longer follow-up period would be necessary to more precisely define the efficacy, and most appropriate indications for this system.
