The purpose of this study was to investigate the effects of 8 weeks of core training on the abdominal muscle strength, sargent lumps, Y-balance and equilibrium freestyle skiers'. Fourteen freestyle players were randomly assigned to the exercise group(Ex)(n=7) and control groups(Con)(n=7). Ex undertook a 8-week training program that included exercises for the Bench, Sideway bench, and Nordic hamstring whereas Con performed their usual activities. Muscular fitness were significant effect observed, but there was no difference between groups. The Y-balance test was effective in the front left, and the left and right left posteromedial showed significantly differences between the groups. In the total score, the Ex decreased to 7.5cm in the left and right difference and 1.66cm in the post, but the control group increased from 3.73cm in the pre-test to 7.01cm in the post-test. In the Equilibrium test, there was significant result in condition(C) in C2, C5, and C6. In conclusion, the 8-week core training was found to have a beneficial effect on the postural control in freestyle skiers'.

This study was to evaluate the fitness and the suitability of size specification of the ready made jacket for women by analysing pattern size and space between skin and clothing using 3D scanner. The results were as follows: 1. Pattern B had the lowest score and the feeling of wearing was significantly different among the given patterns even though all jacket size specification were the same. 2. Ease amount was different between each brand even though the jacket size specification was the same due to the different pattern grading rules. And increasing grading amounts were bigger in horizontal direction rather than in vertical direction. 3. We could obtain accurate a 3 dimensional figure, using 3D scanner which was very useful and more accurate than 2 dimensional data using photography method. 4. Analyzing the average space between skin and clothing of each pattern, there was no significant difference in the average space between skin and clothing among all patterns except waist part of B88 size. And analyzing the average space between skin and clothing of each measured body parts by each size, there existed a significant difference in the interscye, abdomen and hip parts.

This study was made to draft the tight fitting bodice pattern which horizontal and perpendicular stands are to be lightly set, with the consideration of characteristics of body shape in design of clothes. Measurement of body was conducted on 53 women in twenties, and observation was made on surface development pattern by adhesive tape addition method and gypsum method on three standard objects. In the study, bodice pattern was completed by using already made Somato- measurer, compared with existing bodice pattern, and the results are as follows. The result of the correlation analysis by body measurement shows that chest circumference has a relation to B$.$P-front neck point, side neck point, shoulder point, front interscye breadth point, and the item in spine scapulae point has relation to the item of back neck line, and front & back horizontal values. The degree of shoulder slant, width of armhole and of its depth, the amount of breast, back space, back length were shown to be directly measured from the body. In surface development pattern, tight-fit bodice pattern necessary to the breast volume and back space were shown to be investigated and these volume have to be given in setting up basic line for clothes design together with body measurement value. The result of sensory evaluation for appearance test on fitness shows higher value of research bodice including line of shoulder line, front and back interscye breadth, chest circumference, waist circumference, armhole circumference and of its depth, compared with the research bodice in most items. The result of this study is seen showing high effectiveness for the basic data to design the ready-made dress of high sensitivity of high value added tat.

The purpose of this study was to determine the effects of aerobic rhythmical exercise program on $VO_2$ max, leg strength, grip strength, flexibility, exercise self-efficacy and quality of life in elderly. This quai-experimental study was designed as a non-equivalent control group pretest-posttest study. 36 subjects, aged between 65 and 73 years who have normal cognition. sensory function and cerebellum function participated in this study. 19 experimental group subjects participated aerobic rhythmical exercise program. Aerobic rhythmical exercise program was developed on the basis of calisthenics, stretching, aerobic exercise, Korean traditional dance and music by the author. The program consisted of approximately 1 hours of exercise, 3 times a week for 9 weeks. During 1 hours workout, there were 15 minutes of warm-up dancing, 35 minutes of conditioning dance and 10 minutes of cool-down dancing. The intensity for the conditioning phase was between $40\%\;and\;60\%$ of age adiusted maximum heart rates. The $VO_2$ max, grip strength, leg strength, flexibility, exercise self-efficacy and quality of life were measured prior to and following the experimental treatment. Data were analyzed with $x^2-test$, t-test, mean, standard deviation. percentage of change and ANCOVA test using SAS program. Results were obtained as follows. 1. The $VO_2$ max of the experimental group were significantly lower than those of the control group following the aerobic rhythmical exercise program(F=7.76, p=0.008). 2. The grip strength of the experimental group were significantly lower than those of the control group following the aerobic rhythmical exercise program(F=4.61, p=0.039). 3. The leg strength of the experimental group were significantly lower than those of the control group following the aerobic rhythmical exercise program(F=9.29, p=0.000). 4. The was no significantly difference of flexibility between experimental and control group 5. The self-efficacy of the experimental group were significantly lower than those of the control group following the aerobic rhythmical exercise program(F=43.40, p=0.000). 6. The quality of life of the experimental group were significantly lower than those of the control group following the aerobic rhythmical exercise program(F=8.91. p=0.005). The results suggest that aerobic rhythmical exercise program can improve $VO_2$ max, grip strength. leg strength. exercise self-efficacy and quality of life elderly. Thus. aerobic rhythmical exercise program was a useful nursing intervention for elderly.
