Purpose: The purpose of this study was to investigate the effect of a comprehensive rehabilitation program on physical function, immune response, fatigue and quality of life in mastectomy patients. Method: The subjects included fifty-five patients with breast cancer (27 in the control group and 28 in the experimental group). The subjects in the experimental group participated in a comprehensive rehabilitation program for10 weeks, which was composed of 1 session of education, 2 sessions of stress management, 2 sessions of exercise, and 1 session of peer support group activity per week. Result: The results revealed anincrease in shoulder extension, abduction, external rotation, and internal rotation of the affectedupper extremity, and in shoulder extension and abduction of the healthy upper extremity. Also an increase in quality of life and a decrease in fatigue were significantly higher in the experimental group than the control group. However, the results revealed that the natural killer cell ratio of the experimental group increased but there was no significant difference from that of the control group. Conclusion: The 10-week comprehensive rehabilitation program showed a large affirmative effect on physical function, fatigue and quality of life of breast cancer patients after a mastectomy.

Purpose: This study was conducted to develop a health education program for preschoolers who have defected from North Korea with their mothers, and to evaluate the effects on health knowledge and behavior. Methods: A non-equivalent control group pre-post test design was used with 58 preschoolers who were assigned to either the experimental or control group (29 for each group). The program was composed of five sessions in health education and contracts. To test the effectiveness of the intervention, health knowledge and behaviors, and total bacterial colony counts on hands were measured at one pretest and two post tests (1 week and 4 weeks after the intervention ended). Data were analyzed using the SAS program. Results: Health knowledge and behavior in the experimental group increased significantly compared to the control group. The effects of the intervention were evident even at 4 weeks after the intervention ended. Total bacterial colony counts in the experimental group decreased significantly at the 1 and 4 week posttest intervention compared to the control group. Conclusion: Results indicate that this program is effective in improving health knowledge and behavior in these children and therefore can be utilized to ensure efficient management their health care.

PURPOSE: This study investigated the efficacy of interferential current (IFC) treatment on the improvement of pain, disability, and balance in patients with chronic nonspecific low back pain. METHODS: A double-blind randomized clinical trial was conducted with 40 patients with chronic nonspecific low back pain. The patients were randomly allocated into two groups: the IFC treatment group (n = 20) and the placebo treatment group (n = 20). The IFC group received 30 minutes of IFC treatment on the lumbar region, while the placebo group received IFC treatment without real electrical stimulation. The intervention was administered five days a week for two weeks. RESULTS: The primary outcomes of resting pain and pain during functional movement were measured by a visual analogue scale. The secondary measurements included the Oswestry disability index (ODI) for low back pain and postural sway. The measurements were performed before and after the two-week intervention period. Compared to the placebo treatment group, the IFC treatment group showed significantly greater improvement in pain during anterior trunk flexion in the standing position (p = .029), ODI (p = .039), and postural sway when subjects stood with their eyes closed (p = .010) at the end of the intervention. CONCLUSION: Our findings show that IFC treatment can improve pain, disability, and postural sway, thus, highlighting the benefits of somatosensory stimulation from IFC.

Purpose: This study investigated the changes in body composition and serum lipid composition in obese women that were caused by a 12-week circuit exercise regime including both field and aquatic activities. Methods: Subjects comprised a total of 36 women who had a BMI of more than $25kg/m^2$. The simple obesity group (n=17) had no current or past record of medical complications, whereas the group with complications (n=19) also suffered from hypertension and/or diabetes. The circuit exercise program consisted of 12 weeks of 60%HRmax exercise sessions, five days a week. Results: While changes in every variable of body composition were significant, there was no statistically significant difference in the changes in serum lipid composition variables. With the exception of BMI, the correlation between the simple/complicated groups and exercising was statistically insignificant. Conclusion: These findings suggest that while a complex circuit weight exercise program that includes aquatic exercises significantly and positively alters obese patients' body composition it does not create statistically significant changes in their serum lipid composition. It can still be concluded, however, that increasing the duration of the exercise program would be effective to influence this. Moreover, personalized exercise programs that fit the needs of the individual participants seem necessary, given that the effect of exercise on body composition and serum lipid composition was greater in patients with simple obesity than in those with complications.

Purpose: The purpose of this study is to examine the effects of using a horseback riding simulation on static balance in children with cerebral palsy. Methods: This study was conducted with 30 children with cerebral palsy at levels I~IV in the Gross Motor Function Classification System (GMFCS), who were randomly divided into a control group and a hippotherapy group. Both the control group and the experimental group received NDT for 30 minutes per session, four times per week, for ten weeks, while the experimental group also received hippotherapy, 15 minutes per session, four times per week, for ten weeks, after the neurodevelopmental treatment (NDT). The horseback riding simulators JOBA (JEU7805, Panasonic, 일본) used in this study simulated actual horse movements; static balance was measured in each group before the exercise and five weeks and ten weeks after the beginning of the exercise using a pedoscan system (Diers Pedo, Germany). Results: The intergroup effects on static balance were tested, and the results showed no significant differences (p<0.05). Conclusion: The horseback riding simulation exercise was shown to be effective for the static balance of children with cerebral palsy. Therefore, additional studies should be conducted with more children with CP divided according to type.

Objectives : The purpose of this study is to systematically analyze the effect of Tai Chi as therapeutic exercise on depressing blood pressure. Methods : We reviewed articles published in the PubMed, Chinese Academic Journals(CAJ) and five Korean databases. The searching keywords were "Tai chi AND blood pressure" and "Tai chi AND hypertension". We evaluated the quality with Cochrane risk of bias tool. Results : In the 114 articles searched, 7 randomized controlled clinical trials were selected. Yang(楊) style Tai chi, exercising over 30 minutes a time and over three times a week, had an effect on decreasing blood pressure. However, Wu(吳) style Tai chi was not effective in decreasing blood pressure. Conclusions : Usual exercises for hypertension patients should be performed in the form of moderate exercises intensity for 10-26 weeks by 30-60 minute a time, over 3 times a week. The study of Tai Chi on blood pressure needs to follow this criteria in the future.

The first purpose of this study was to compare kinematic variables during spinning motion with or without upper extremity and identify the most effective spinning method. The second purpose of this study was to compare functional difference between novice and elite dancers with the term of training. Ten experienced female dancers and ten novices were recruited as subjects for this study. Elite group was asked to perform turn motion with three types of upper extremity. Novice group has taken training of spotting technique for five weeks. Four Falcon HiRES cameras were used to analyze kinematic variables including head angular velocity and CG displacement during spinning. These data were sampled before training, after 3-week, and 5-week of training. Eight different events in two consecutive turns were defined for statistical comparison. One-way ANOVA was performed to compare among the kinematics of turning motion with three types of upper extremity. Independent t-test also used to compare kinematics between elite and novice at three different length of training. As results, spinning with both arm increased angular velocity and stability compared to the turning motion with one arm or with arm strapped and found out that the turn with both arm was the most effective way of spin. Also, for novice dancers, three weeks of training were needed to complete spinning motion.

This study was conducted to evaluate the influence of diets containing genistein and soy extract on the growth of MDA-MB-231 cells implanted into female Balb/c mice. Four-week-old female athymic nude mice (Balb/c) were acclimated to an AIN-93G control diet for 1 week and then injected MDA-MB-231 cells ($1{\times}10^6$/site) and were continued on the on AIN-93G control diet. Five weeks after injecting the MDA-MB-231 cells ($1{\times}10^6$/site), two experimental groups were assigned to diets containing genistein (750 ${\mu}g/g$ AIN-93G diet) or 0.6% soy extract (containing genistein at 750 ${\mu}g/g$ AIN-93G diet) until they were sacrificed. Tumor growth was significantly reduced in the groups treated with genistein and soy extract compared to the control group. The results of the proliferating cell nuclear antigen (PCNA) assay also revealed that genistein and soy extract treatment reduced the proliferation of MDA-MB-231 cells in vivo. In the present study, dietary isoflavone was provided just before solid tumor formation, and thus the timing of dietary isoflavone administration may be critical to the suppression of tumor growth.

A total of 60 growing pigs (25.50 ± 1.63 kg) were used in a 6-week trial to investigate the effects of diet supplementation with brewer's yeast (Saccharmyces cerevisiae) on growth performance, nutrient digestibility, and fecal score of growing pigs. Pigs were randomly allocated to one of two dietary treatments [six replications (five pigs·pen^-1)] according to initial body weight. The dietary treatments included: 1) control, basal diet (CON); 2) basal diet supplemented with 1% brewer's yeast. Dietary supplementation with brewer's yeast showed significant improvement in body weight (BW) at weeks 4 and 6; the average daily gain (ADG) and gain : feed ratio (G/F) was higher during week 4 and overall compared with CON (p < 0.05). Brewer's yeast supplementation in the diet had no significant on the nutrient digestibility. There was no significant difference in the fecal score of CON and brewer's yeast supplementation in the diet. In conclusion, the results indicate that dietary supplementation with brewer's yeast can improve growth performance in growing pigs. The results showed that supplementation of brewer's yeast in the diet of growing pigs had a positive effect on the ADG in growing pigs, but no significant effect on nutrient digestibility and fecal score when supplemented with brewer's yeast in the diet of growing pigs.

The aim of the present study was to examine whether repetitive transcranial magnetic stimulation (rTMS) can improve gait ability of acute stage stroke patients. This study was conducted with 39 subjects who were diagnosed as having a hemiparesis due to stroke. The experimental group included 20 subjects who underwent repetitive transcranial magnetic stimulation and the control group included 19 subjects who underwent sham therapy. The stroke patients in the experimental group underwent conventional rehabilitation therapy and rTMS was applied daily to the hotspot of the lesional hemisphere. The stroke patients in the control group underwent sham rTMS and conventional rehabilitation therapy. Participants in both groups received therapy five days per week for four weeks. Temporospatial gait characteristics, such as stance phase, swing phase, step length in affected side, velocity, and cadence, were assessed before and after the four week therapy period. A significant difference was observed in post-treatment gains for the step length in the affected side, velocity, and cadence between the experimental group and control group ( p < 0.05). However, no significant differences were observed between the two groups on stance phase and swing phase ( p > 0.05). We conclude that rTMS may be beneficial in improving the effects of acute stage stroke on gait ability.
