The aim of this study was to analyze the isokinetic strength of ankle, lumbar and shoulder in fin swimmers. For this study, 7 male fin swimmers and 7 men general swimmers were selected. Isokinetic strength of ankle, lumbar and shoulder were measured by Biodex System 3,000. Statistical techniques for data analysis were a descriptive statistics and t-test. The results of this study were as following; The first, significant difference between two groups in right and left plantar flexion of ankle at $30^{\circ}/sec\;and\;180^{\circ}/sec$. But no significant difference was found between right and left in two groups. The second, significant difference between two groups in right dorsiflexion of ankle at $30^{\circ}/sec$. The third, significant difference between two groups in extension of lumbar at $60^{\circ}/sec$. The fourth, significant difference between two groups in right flexing of shoulder at $60^{\circ}/sec$ and $180^{\circ}/sec$. As result of this conclusion, the isokinetic strength of ankle and lumbar in fin swimming group showed significantly higher than non-fin swimming group.

"Lolita," a novel by a Russian-American novelist, Vladimir Nabokov, has been the center of controversy since its first publication in 1955. As it gained wide fame across culture, it has exercised a great influence, altered or developed to diverse forms. Lolita, the title of the novel as well as the heroine's name, now takes a significant part in our society through all cultures and is used as various meanings and symbols. The purpose of this study is to reanalyze and reinterpret the current use of Lolita based on the characteristics initially portrayed in Nabokov's novel. The traits of the heroine were categorized into purity, seductiveness, and dualism and the commercial use of each in the mass media and fashion in Korea was closely examined. First, purity was interpreted as the archetypal image of a 12-year-old girl, while seductiveness was construed to involve temptation and enticement, ultimately leading a man astray. The dualism of an under-aged sexualized nymphet delineated in the novel as a poor little girl as well as a depraved temptress was stated as another trait of Lolita.

Purpose: The purpose of this study was to investigate the effects of lumbar stabilization exercise on balance ability in patients with adolescent idiopathic scoliosis. Methods: This study was one group pretest-posttest design. Twenty young idiopathic scoliosis patients were recruited for this study. They had the lumbar stabilization exercise program for 40 minutes a day, three times per week for 3 weeks. The lumbar trunk muscle endurance test and clinical balance tests (functional forward reach, functional lateral reach, Fukuda 50-stepping, one leg standing with eyes open and eyes closed) were measured before and after the lumbar stabilization exercise. Results: There were significant differences between pre-and post-test in absolute value of the difference between right and left lateral reach, distance of Fukud 50-stepping and one leg standing on the each side with eyes closed(p<.05). The results showed that the lumbar trunk muscle endurance significantly increased(p<.05). Conclusion: In this study indicated that the lumbar stabilization exercise was effective on balance ability and lumbar trunk muscle endurance in patients with young idiopathic scoliosis.

The purpose of this study were to examine the effect of two different pelvic alignments and the back belt on electromyographic(EMG) activity of the erector spinae during lifting. The results were as follows: 1) EMG activity of erector spinae was greater when the pelvis was tilted anteriorly than when the pelvis was tilted posteriorly during lifting. 2) EMG activity of erector spinae was greater when the back belt than when without the back belt during lifting. These results suggest that the greater EMG activity of erector spinae with an anterior pelvic tilt position and with back belt during lifting may ensure optimal muscular support for the spine while handling loads.

Purpose: The purpose of this study was to determine the effects of the hand acupressure and lumbar strengthening exercise on young adult women with back pain. Methods: The study used a nonequivalent control group pretest-posttest design. The subjects consisted of 37 female young adults (19 persons in the experimental group and 18 persons in the control group). The hand acupressure and strengthening exercise for lower back were developed by the investigator and a hand acupressure expert. The experimental group was exposed to this program 5 days a week for 4 weeks. The visual analog scale, back muscle strength, flexibility, and quality of life were used as measurement instruments. The data were analyzed with frequency, t-test, and repeated measures ANOVA using SPSS 18.0. Results: In this study, the hand acupressure and strengthening exercise showed siginificant effects on the back muscle strength, flexibility, and quality of life in the experimental group compared to the control group. However, back pain score was not significantly decreased after the program. Conclusion: The study suggests that this program can be applied for the women with low back pain in order to enhance the back muscle strength, flexibility, and quality of life.
