The purposes of this study were to investigate kinematic parameters of racket head and upper extremities during squash back hand stroke and to provide quantitative data to the players. Five Korean elite male players were used as subjects in this study. To find out the swing motion of the players, the land-markers were attached to the segments of upper limb and 3-D motion analysis was performed. Orientation angles were also computed for angular movement of each segment. The results were as follows. 1) the average time of the back hand swing (downswing + follow-through) was 0.39s (0.24 s + 0.15 s). 2) for each event, the average racket velocity at impact was 11.17m/s and the velocity at the end of swing was 8.03m/s, which was the fastest swing speed after impact. Also, for each phase, 5.10m/s was found in down swing but 7.68m/s was found in follow-through. Racket swing speed was fastest after the impact but the swing speed was reduced in the follow-through phase. 3) in records of average of joints angle, shoulder angle was defined as the relative angle to the body. 1.04rad was found at end of back swing, 1.75rad at impact and it changes to 2.35 rad at the end of swing. Elbow angle was defined as the relative angle of forearm to upper arm. 1.73rad was found at top of backswing, 2.79rad at impact, and the angle was changed to 2.55rad at end of swing. Wrist angle was defined as the relative angle of hand to forearm. 2.48rad was found at top of backswing, 2.86rad at impact, and the angle changes to 1.96rad at end of swing. As a result, if the ball is to fly in the fastest speed, the body has to move in the order of trunk, shoulder, elbow and wrist (from proximal segment to distal segment). Thus, the flexibility of the wrist can be very important factor to increase ball speed as the last action of strong impact. In conclusion, the movement in order of the shoulder, elbow and the wrist decided the racket head speed and the standard deviations were increased as the motion was transferred from proximal to the distal segment due to the personal difference of swing arc. In particular, the use of wrist (snap) may change the output dramatically. Therefore, it was concluded that the flexible wrist movement in squash was very important factor to determine the direction and spin of the ball.

The purpose of this study was to examine the effects of the stretching and recreation exercise including health education on physical flexibility and health behavior compliance of women in elderly. Subjects included 28 women elderly who were residents of H Dong, Dondae moon-Gu, Seoul. The treatment intervention was applied during total 8 weeks as 5 times/week for stretching exercise with 2 times/weeks for health education. Data collection were from February to April, 2004. SPSS Window program was used by aims of this study for data analysis. The results were as following: 1. 75 old age above (39.3%) was the most of age in subjects. None education (42.9%) was the most of subjects in this study. Perceived health state was the most as 71.4% in moderate and good health state. 2. Physical flexibility of both shoulder(right z=-4.301, p=,000)(left z=-4.306), both arm(right z=-3.623, p=.0001)(left z=4.111, p=.0001), heel on both ankle(right z=-3.472, p=.0001) (left z=956, p=.0001), both before food(right z=-4.205, p=.0001)left(z=4.191, p=.0001) and both knee(right z=-4.118, p=.0001)(left z=4.082, p=.0001) was increased after 8 weeks more than before stretching and recreation exercise including health education were done. 3. Health behavior compliance(z=-4.073, p=.0001) was significantly on the effect. Therefore, it is confirmed that stretching exercise included health education is an effective nursing intervention for physical, mental, and psychological health management in elderly. Accordingly, authors are proposing that variously effective health management exercise programs must be developed for elderly, at the same time, the application and following up on the programs will be more important in the future.

The purpose of this study : 1. The total 56 range measurements of active dynamic motion of 40 subjects (20's and 30's) were measured using 3-D dynamic motion analysis system. 2. Various comparisons were performed for the right and left side, male, age groups (20's, 30's, and 40's ∼ 60's) using previous studies. The results were compared with the other studies in the aspects of age. In this study, the 3-D motion analysis system based on photogrammetry was established and used to analyze the human's motion and posture. The system consists of VICON 140, data acquisition system, and data analysis program (KRISSMAS). The result of this study were as follows : 1. Comparing 20's with 30's the result shows that 30's have larger ROM at some joints, which is inconsistent with the previous result. The reason is that female subjects in 20's were improperly sampled according to the representatives of anthropometry characteristics. 2. There are significant differences in some joints related with age. 20's male subjects have more flexible joints in the neck while 30's male subjects have more flexibility in their shoulder joint and elbow joint. But most of the significances were not high (p〈0.05). The prediction that the right side of Korean bodies would be more flexible was not a good hypothesis. And the joints flexibilities are not correlated with Rohrer's Index.

This study develops a post-operative brassiere suitable for changed breast shapes and the characteristics of breast augmentation patients. Six subjects who experienced breast augmentation surgery with a cup size of C or D cup participated in the wearing test. We conducted a wearing test to evaluate the superiority of the developed post-operative bra. As a result, the evaluation of the developed bra was excellent in the outer cup, outer circle of breast front gore, shoulder straps and the wing pressures. Second the satisfaction of the developed brassiere was high in the front center part, and in the evaluation of wearing satisfaction of the subjects; in addition, the degree of close contact with the cup, flexibility, touch, and overall evaluation. The satisfaction of the developed bra was also higher than a commercial bra. Third, the developed bra proved superior in the adaptability test, such as prevention of breast shaking, prevention of bra and breast separation during movements, and ease of body movement.

The purpose of this study was to investigate the effects on skin temperature, pain, muscle tone, and ROM after applying the massage robot "PIRO-ZERO" to 6 men and 4 women in their 20s who complained of non-specific pain in the shoulder or back for more than 12 weeks. As a result of the study, there was a significant increase in skin temperature not only in the area where the massage was applied, but also on the opposite side and throughout the body due to increased blood flow. Pain in the upper trapezius, rhomboid, and erector spinae muscle was decreased, and muscle tone in the erector spinae muscles was significantly decreased. There was a significant increase in ROM of neck and trunk flexion, which is thought to be because the massage reduced muscle tone around the spine, increasing flexibility. In the future, as the safety and effectiveness of massage robots are further verified and the pressure, speed, and path become more diverse, satisfaction is expected to increase.

Purpose: This study was conducted from March to August, 2003 to evaluate the process and outcomes of a program to promote healthy joints in older adults residing in the community. Method: A quasi experimental research design (one group pretest posttest design) was used in this study. The participants were 26 older adults (but 74 older adults also participated in a program immediately after the study program). Program had 4 sessions (8 hours) once a week. Data were collected before the program, immediately after and 4 weeks after the program was completed and were analyzed with paired t-test. Results: The level of a satisfaction, interest and understanding of the program were high. Significant differences were found in the health state, the flexibility of neck and shoulder joints and joint exercise habits between the scores before the program started and 4 weeks after it finished. Conclusion: This results suggest that the joint health promotion program for older adults in the community developed this study is effective. So this program can be recommended as an effective nursing intervention for joint health promotion in older adults living in the community.
