The purpose of this study was to analyze the kinematic variables of glide kip motion on the uneven bars through a two-dimensional cinematography. Three expert female gymnastics players were involved in the data gathering process. The followings were concluded according to the results. The arm, trunk and leg segments were fully extended throughout the kip movement. The whole body center of gravity showed the biggest changes during 66 to 87% of the kip motion. During the kip phase, the horizontal displacement of the leg was greater than the vertical displacement the leg. Glide kip motion should be done in orders of upward movement of leg, forward movement of leg, upward movement of trunk and forward movement of trunk segment. It was found that trunk segment and hip joint movements showed bigger changes than those of leg segment and shoulder joint in the glide kip motion. The largest angular velocity of hip joint was shown in the middle of the kip Phase. In conclusion, effective kip movement could be resulted when the trunk was displaced posterior-upward direction with fast hip joint extension after the leg segment was elevated upward and thrusted forward in advance.

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.

Purpose: This study was done to identify the effects of stress management program on perceived stress, geriatric depression, and somatic symptom in elderly Korean subjects. Methods: A pre-post test design with a nonequivalent control group was used. Fifty elderly Korean subjects with mild depression were recruited from the registerants at four public senior citizen centers within S-gu in Seoul. They were randomly allotted to the experimental group(n=25) and control group(n=25). The intervention was performed for one hour each week at each center for 5 weeks. The effects were measured by Perceived Stress Scale, Geriatric Depression Scale-Korean, and Patient Health Questionnaire-15. Results: Perceived stress and depression were significantly reduced in experimental group. The somatic symptom was not significantly different in the experimental group. Conclusion: The stress management program may have merit in improving mental health of elderly Koreans, although this conclusion is equivocal pending further well-controlled studies that include mediation techniques such as conversion therapy and health gymnastics.

The purpose of study was to investigate the kinematic variables of Kenmotsu motion in Parallel bars. To this study, by 3 dimensional kinematical analysis of 4 male national gymnasts participants in the 28th Athens Olympic Game in 2004, kinematic data collected using video camera. Coordinate data were smoothed by using a fourth-order Butterworth low pass digital filter with cutoff frequency of 6Hz. The conclusions were as follows. 1. In P2, because the constrained swing movement made the movement of a rising back difficult7, the movements of Reg. were performed at low position after Air phase. 2. In E5 event, for the shake of a stable handstand and applied techniques like a Belle(E-value), a Belle Piked(super E-value), a vertical velocity in E2, a horizontal velocity in E3 and a vertical velocity in E4 were necessary for high velocities. 3. In E4 event, it was appeared that for a flexible body's movement of a vertical up-flight, the large angle of the shoulder joint and the flexion & extension of the hip joint were necessary in Air phase and a long flight time and vertical displacement made Reg. movements stable at the high position.

PURPOSE: The purpose of the present study is to investigate the changes in the cognitive function of elderly dementia patients residing in a residential care facility, following six weeks of brain-computer interface (BCI)-based cognitive training and to determine whether BCI-based cognitive training effectively improves their cognitive functions. METHODS: Thirty subjects diagnosed with dementia were randomly assigned to either the experimental or control group. Pre- and post-test cognitive function assessments were conducted using the mini mental state examination-Korean (MMSE-K) and Korean-dementia rating scale (K-DRS). The experimental group received BCI-based cognitive training, which consisted of games such as flying a ball and exploding a bomb, while the control group participated in music listening activities and National Health Gymnastics. Both groups engaged in a total of 18 sessions (3 times per week for 6 weeks, for 40 minutes per session). RESULTS: After 6 weeks of intervention, the experimental group had significantly increased MMSE-K scores ($19.53{\pm}1.30$ to $22.20{\pm}1.15$; p<.0011) and total K-DRS scores ($87.20{\pm}4.16$ to $99.33{\pm}1.15$; p<.0011). In addition, the experimental group showed greater cognitive improvements than the control group. CONCLUSION: The results of this study suggest that BCI-based cognitive training is a positive intervention tool for improving the cognitive function of dementia patients.
