The objective of this study is to identify the kinematic variables of giant swing backward to handstand as well as individual variations of each athlete performing this skill, which in turn will provide the basis for developing suitable training methods and for improving athlete's performance in actual games. For this end, 3 male athletes, members of the national team, who are in ${\Box}{\Box}H{\Box}{\Box}$ University, have been randomly chosen and their giant swing backward to handstand performance was recorded using two digital cameras and analyzed in 3 dimensional graphics. This study came to the following conclusion. 1. Proper time allocation for giant swing backward to handstand are: Phase 1 should provide enough time to attain energy for swing track of a grand round movement. The phase 3 is to throw the body up high in the air and stay in the air as long as possible to smoothen up the transition to the next stage and the phase 4 should be kept short with the moment arm coefficient of the body reduced. 2. As for appropriate changes of locations of body center, the phase 1 should be comprised of horizontal, perpendicular, compositional to make up a big rotational radius. Up to the Phase 3 the changes of displacements of vertical locations should be a good scale and athlete's body should go up high quickly to increase the perpendicular climbing power 3. When it comes to the speed changes of body center, the vertical and horizontal speed should be spurred by the reaction of the body in Phase 2 and Phase 3. In the Phase 4, fast vertical speed throws the body center up high to ensure enough time for in-the-air movement. 4. The changes of angles of body center are: in Phase 2, shoulder joint is stretching and coxa should be curved up to utilize the body reaction. In the Phase 4, shoulder joint and coxa should be stretched out to get the body center as high as possible in the air for stable landing. 5. The speeds of changes in joints angles are: in the Phase 2 should have the speed of angles of shoulder joints increase to get the body up in the air as quickly as possible. The Phase 3 should have the speed of angles in shoulder joint slow down, while putting the angles of a knee joint up to speed as quickly as possible to ensure enough time for in-the-air movement.

목적: 근위 상완골 골절의 치료 방법은 일반적으로 Neer 분류법에 의하고, 심하게 전위된 3분 골절 및 4분 골절의 경우 상완골두 치환술의 적응증이 된다. 저자들은 근위 상완골의 분쇄 골절로 인하여 상완골두 치환술을 시행 받고, 최소 1년 이상 추시 가능하였던 10례의 단기적 임상적 결과를 보고 하고자 한다. 대상 및 방법: 저자들은 1999년 7월부터 2005년 3월까지 상완골 근위부 골절로 상완골 두 치환술을 시행 받은 환자 중 최소 1년 이상 추시 가능 하였던 10명(10 견관절)의 환자를 대상으로 하였다. Neer 분류법에 의하면 5명은 3분 골절이었고, 나머지 5명은 4분 골절이었으며 외상 후 수술까지 소요 시간은 평균 6.1일 이었다. 남자 4명, 여자 6명이었고, 평균 연령은 67.4세(최소 56세, 최고 76세)였다. 술 후 견관절 기능은 Constant score와 SST(Simple shoulder test) 및 UCLA 평가법(modified UCLA score for hemiarthroplasty)을 이용하여 평가하였다. 결과: 최종 방문 시 Constant 점수는 평균 51.4(최저 34점, 최고 60점)점이었고, 변형된 SST의 경우는 12개 문항 중 평균 7.8개 문항이 가능하다고 하였다. 수상 당시 액와동맥 파열 및 상완신경총 손상이 있었던 1예를 제외한 경우 Constant score는 평균 53.5(최저 44점, 최고 60점)점 이었고, SST의 경우는 12개 문항 중 평균 7.2($1{\sim}8$)개 문항이 가능하다고 하였다. 최종 추시 UCLA score는 동통, 기능성, 근력 및 운동 범위 항목 각각이 평균은 8.2($6{\sim}10$)점, 6.6($2{\sim}8$)점, 6.9($4{\sim}8$)점 이었고, 총점 21.7($12{\sim}26$)점 이었다. UCLA 평가법에 의한 결과는 우수 3예, 양호 6예, 불량 1예 이었고 불량의 경우는 혈관 및 신경 손상이 있었던 1예 이었다. 환자의 주관적 만족도는 10명의 환자 중 2명의 환자는 흡족, 7명의 환자는 양호한 결과라고 하였으나, 1명의 경우는 불만이었다. 결론: 단기 추시 결과이지만, 상완골 두 치환술은 관혈적 정복술이 어려운 상완골 근위부 골절에있어서 일차적 치료방법이라고 생각된다. 상완골 두 치환술은 고령의 환자에게 있어서 강직을 예방할 수 있고 일상적인 생활이 가능하도록 하는 수술 방법이나, 관절운동 범위 및 근력의 회복은 충분하지 않았다.

Purpose : To evaluate the neurologic abnormalities in the donor limb after contralateral C7 transfer in brachial plexus injury. Materials and Methods : From August 1996 to December 1999, five patients with brachial plexus injury were treated with contralateral C7 nerve root transfer. The average follow up was 16 months(range, 5 to 36 months). The clinical findings were assessed using the British Medical Research Council Grading System, and also measured grip power, pinch power of hand and two point discrimination of the fingers. Results : We had no difference in shoulder abduction and elbow flexion after contralateral C7 transfer. The grip and pinch strength were recovered within 4weeks. Sensory loss occurred in all patients and was noted to be more severe on index and middle finger. Four patients recovered within 2 weeks, one continued till one year. Subjective numbness and pain on percussion minimally persisted until last follow-up. Conclusion : The division of the C7 nerve root resulted in minimal and temporary functional deficit in the donor upper limb.

Purpose: The purpose of this study was to investigate the effects of constraint-induced (CI) movement using self-efficacy on U/E function of chronic hemiplegic patients. CI movement discourages the use of the unaffected U/E, combined with intensive training of the affected U/E. Method: A non-equivalent pretest-posttest design was used. Study subjects were 40 hemiplegic patients conveniently selected from 2 different community health centers. The experimental subjects participated in the CI movement program for 6 hours daily over a period of two weeks. The exercises for affected U/E consisted of warming up, main exercise and ADL practice. To encourage the participants' behaviors self-efficacy enhancing strategies were used, which included performance accomplishment, vicarious experience, verbal persuasion and emotional arousal. Result: After 2 weeks of treatment, the grip power, pinch power, wrist flexion/extension, elbow flexion, and shoulder flexion/extension were significantly higher in the experimental subjects than in the control subjects. However, there was no significant difference in hand functions of the two groups. Conclusion: The above results show that the constraint-induced movement using self-efficacy could be an effective nursing intervention for improving U/E function of chronic hemiplegic patients. Long term studies are needed to determine the lasting effects of constraint-induced movement.

To improve surface wettability, each sample was treated by atmospheric pressure plasma (APP) using dielectric barrier discharge (DBD) system. Argon and oxygen gases were used for treatment gas to modify the $TiO_2$ surface by APP with RF power range from 50 to 200 W. Water contact angle was decreased from $20^{\circ}$ to $10^{\circ}$ with argon only. However, water contact angle was decreased from $20^{\circ}$ to < $1^{\circ}$ with mixture of argon and oxygen. Water contact angle with $O_2$ plasma was lower than water contact angle with Ar plasma at the same RF power. It seems to be increasing the polar force of $TiO_2$ surface. Also, analysis result of X-ray photoelectron spectra (XPS) shows the increase of intensity of O1s shoulder peak, resulting in increasing of surface wettability by APP. Moreover, each water contact angle increased according to increase past time. However, contact angle increase with plasma treatment was lower than without plasma treatment. Additionally, the efficiency of $TiO_2$ photocatalyst was improved by plasma surface-treatment through the degradation experiment of phenol
