The purpose of this study is grasp the problem of the gymnast, Kim, Dong-Hwa's Kip to Swallow Motion in Rings, and make up for the weak points to help him to perform a better performance. Therefore, two tryouts for $28^{th}$ Athens Olympic Games were filmed using video camera then finalized with Kinematical Analysis using 3D motion analysis program followings are the form of conclusions. 1. In the very first tryout, when he was doing a Swallow Support Scale, his CM position was high and arm slope was deduction because when he was doing Kip, the ascent velocity was low and he tried excessively to pull him on rings due to relying upon angular movement of shoulder joint. 2. When he was doing drop, he let his hip angle bend only little bit and let fall so making shoulder angle wider and maintain the level horizontally occurs strong drop motion when vertical descent is happening. 3. As a result, lowering the direction of a kick makes CM's movement path lower, increase vertical ascent velocity, and it helps to do the Swallow Support motion in short period of time. 4. After a strong drop motion, which is deep and fast, would make rope of ring shake so there is a defect that the body moves to forward area. However, it does not effect in Swallow Support Scale motion. 5. In the second tryout, trunk rotation angle and arm slope was fixed decrease while doing rotary motion. When rotary motion was happening, before the body was going under the rings, maintained his arm slope horizontally so his Swallow Support Scale motion was nearly perfect.

This study was intended to contribute to allowing athletes to raise a technical understanding of two motions of high difficulty such as the Swallow motion and the Nakayama motion and enhance their competitive power by analysing the kinematical factors required to link those two motions on the competitive scene on the rings for current national athletes. For this purpose, the game of the ring event was videotaped for male heavy gymnasts participating in the final elimination match of the 2004 Athens Olympic Games. This study attempted to select the performing motions of the final 1st-and 2nd-place athletes performing the linking motions from the Swallow motion and the Nakayama motion using the DLT(direct linear transformation) method. As a result, it arrived at the following conclusion : A1 properly performed the flexing and extending movements using the angular velocity of the segment and joint as the switching motion using the body at the time of linking the motion from the Swallow skill to the Nakayama skill. A2 was evaluated to perform the skill taking the form of depending on the force at the static state. Therefore, it is thought that A1 should take care of shaking at the time of using the elasticity of the body. It is thought that in case of A2 the proper use of the elasticity of the body take care of shaking at the switching motion while taking advantage of the force will contribute to his competitive power.

The objective of the study is to analyze the myoelectrical activity involved in performing the Swallow movement, a D-level technique, in order to use it as the basic research data in helping train gymnasts in how to perform strength-related techniques. To this end, four national representative athletes who participated in the 2002 Busan Asian Games were selected. The results of the comparison analysis of the individual models are summarized as follows. 1) The results of the E.M.G analysis showed that during the Swallow movement, the myoelectrical activity was detected higher in pectorialis major muscle and bicep brachii muscle than in trapezius muscle and deltoid muscle. 2) The results of the E.M.G analysis showed that during the Swallow movement, the myoelectrical activity was measured high in triceps brachii muscle and palmaris longus muscle, while the myoelectrical activity was recorded low in latissimus dorsi muscle and rectus abdominis muscle. 3) In performing the Swallow in the rings, the mean average (%) was found high in the order of erector spinae, pectorialis major muscle, palmaris longus muscle, triceps brachii muscle, deltoid muscle, latissimus dorsi muscle, and trapezius muscle. All taken together, the athletes showed a difference in the distribution of the muscles during the performance of the Swallow. The muscle that showed a constant distribution among the athletes was pectoralis major muscle, which proves that for a stable performance, it is ideal to increase the myoelectrical activity in pectoralis major muscle.

본 연구는 뇌졸중 환자들의 대표적인 후유증인 삼킴 장애의 양상을 14개의 하위 항목으로 분류하고 그 특징을 조사하는데 그 목적이 있다. 연구 대상자는 소뇌 천막을 기준으로 천막상 병변의 소견을 보이는 아급성 뇌졸중 환자 49명 이었다. 삼킴 문제의 양상을 조사하고 그에 따른 생리학적 근거를 조사하기 위해 모든 피검자에게 비디오투시조영 삼킴 검사를 시행하였으며 삼킴 장애 평가에는 삼킴 장애 프로파일(The Modified Barium Swallowing Impairment Profile, MBSImP)이 사용되었다. 조사 결과, 뇌졸중 환자의 95.9%는 입술 조절기능에서 문제가 있었고 98%는 혀 조절 기능에서 문제가 있었다. 또한 환자의 57.1%는 음식물을 인두쪽으로 이동시키는데 문제가 있었으며 51%는 구강에 음식물의 일부를 남기는 증상을 나타내었다. 음식물이 인두족으로 유입됨과 동시에 일어나는 인두 삼킴 반사의 경우에는 89.8%의 환자가 지연된 삼킴 반사 증상을 보였으며 후두와 설골의 운동은 각각 42.9 %와 87.8% 환자가 문제가 있는 것으로 조사되었다. 또한 연구개는 환자의 18.4%가 이상 소견을 보였고 후두개의 경우에는 단지 4.1%만이 이상 소견을 보여 대체로 후두개 기능은 잘 보전되어 있는 것으로 조사되었다. 뇌졸중 환자의 30.6%는 후두 폐쇄 기능에 문제가 있었고, 식도 근육의 경우에는 모든 환자(100%)가 이 근육의 상부를 적절히 조절하지 못하는 것으로 조사되었다. 혀 기저부 움직임 또한 환자의 91.8%에게서 문제가 있는 것으로 나타났으며 인두에 음식물을 남기는 증상도 91.8%의 환자에게서 관찰되었다. 본 연구의 결과로부터 뇌졸중 환자의 삼킴 문제의 구체적 양상들에 대해 살펴보았으며 이는 삼킴 장애 중재 및 치료 개발을 위한 기초 자료로 활용 될 수 있을 것이다.
