목적 : 본 연구의 목적은 비디오 자기 모델링 기법(video self-modeling)이 아스퍼거 증후군 청소년의 운 동수행기술에 미치는 영향을 알아보기 위함이다. 연구방법 : 연구 대상은 아스퍼거 증후군으로 진단받은 3명의 청소년이었고, 연구 설계는 개별사례 실험 연구 (single subject experimental design)중 ABA' 설계와 교대중재설계(alternating treatments design)을 함께 사용하였다. 실험은 기초선 과정(A1)이 3회 진행되었고, 비디오 자기 모델링 기법 (B) 4회, 재 기초 선 과정(A2) 3회로 총 10회기로 이루어 졌다. 독립변수는 자신의 행동을 모델링 하는 방법인 비디오 자기 모델링기법을 사용하였으며, 종속변수로 운동수행기술과 캐나다 작업수행측정(Canadian Occupational Performance Measure; COPM)의 수행도 및 만족도를 측정하였다. 운동수행기술은 매 회기 수행시간과 수행의 질로 평가하였고, COPM은 치료 전과 후에 측정하였다. 결과는 시각적 그래프를 통해 제시하였다. 결과 : 3명의 대상자 모두 기초선에 비해 비디오 자기 모델링 기법 적용 후 운동수행시간이 중재 적용 후 점차 감소하는 경향을 보였고, 운동의 질은 향상되었다. 또한 재 기초선 기간동안 대상자 모두 습득한 기술이 유지되었다. COPM을 사용하여 대상자들의 농구 드리블에 대한 수행도, 만족도를 살펴본 결과 유의미한 점수가 향상되었다. 결론 : 비디오 자기 모델링 기법 후 모든 대상자의 운동수행기술을 향상시킬 수 있는 유용한 중재법임을 확 인할 수 있었다.
This study is intended to examine the motor skill learning and treadmill exercise on motor performance and synaptic plasticity in the cerebellar injured rats by harmaline. Experiment groups were divided into four groups and assigned 15 rats to each group. GroupⅠ was a normal control group(induced by saline); GroupⅡ was a experimental control group(cerebellar injured by harmaline); GroupⅢ was a group of motor skill learning after cerebellar injured by harmaline; GroupⅣ was a group of treadmill exercise after cerebellar injured by harmaline. In motor performance test, the outcome of groupⅡ was significantly lower than the groupⅢ, Ⅳ(especially groupⅢ)(p<.001). In histological finding, the experimental groups were destroy of dendrities and nucleus of cerebellar neurons. GroupⅢ, Ⅳ were decreased in degeneration of cerebellar neurons(especially groupⅢ). In immunohistochemistric response of synaptophysin in cerebellar cortex, experimental groups were decreased than groupⅠ. GroupⅢ's expression of synaptophysin was more increased than groupⅡ, Ⅳ. In electron microscopy finding, the experimental groups were degenerated of Purkinje cell. These result suggest that improved motor performance by motor skill learning after harmaline induced is associated with dynamically altered expression of synaptophysin in cerebellar cortex and that is related with synaptic plasticity.
This project was conducted in order to examine visual of the elite athletes and compared the different visual abilities between elite and non-elite athletes by employing seven different visual ability tests. After administring the visual ability tests, important visual characteristics which might have important role to become elite athetes were identified. In the second experiment, two different visual abilities(dynamic visual acuity and depth perception) selected in order to examine the visual training effect for baseball hitting performance for these visual abilities had shown the most relevant visual characteristics for batting performance in the first experiment. The results revealed there were different visual characteristics between athletes in different sports (archery, shooting, ice hockey, baseball), and elite and non-elite athletes. The results also found specific relationship between certain visual characteristics and the sports events. The results of the second experiment revealed the subjects in the experiment group(visual training group) improved their visual abilities significantly through specially designed visual training in the laboratory and the improved visual abilities had positive effect on batting performance in the field.
