  • Objective : We suggested the clinical effect of Rainbow therapy on Bell's palsy. Methods : 20 Bell's palsy patients were divided into two groups. One group(A group) was treated by acupunture and the other group(B group) was treated by acupunture and Rainbow therapy. The effect of these treatments was evaluated by Yanagihara's unweighted grading system and House-Brackmann grading system. Results and Conclusions : In Yanagihara's unweighted grading system After 1 week and 2weeks treatment, group B marked more higher than group A in treatment outcome. We discovered that it is significant differences between two groups. After 3 weeks treatment, group B marked more higher than group A in treatment outcome but it is not significant differences between two groups. In House-Brackmann's facial nerve grading system, After 1 week treatment, group B marked more higher than group A in treatment outcome. We discovered that it is significant differences between two groups. After 2 weeks and 3 weeks treatment, group A marked more higher than group A in treatment outcome but it is not significant differences between two groups.

  • This study explores influences of the relationship between social capital and residents' perception in a collective aspects, and also explores the differences of influence between two groups in 10 rural communities. This study conducts regression analysis with residents questionnaires, and analyzes the relationship of influence among the latent factors, and differences between the two groups. As a results, associational network and social trust factors of social capital are identified as the most important factor in the quality of life and residents' attitudes. In addition, the differences in socio-cultural factor of quality of life and residents' attitude between two groups are identified by comparison with the relationship between two groups, although the explanatory power of both groups is not high. To achieve a successful rural tourism based on the result of this study, rural tourism should consider the regional and demographic characteristics, such as age, occupations and education and so on. The major contribution of this study is to confirm that the impact of social capital on the residents' perception would be different by regions in comparison with two groups, and it will be able to provide useful implication for the rural tourism development in the future.

  • To demonstrate the effect of massages on the skeletal muscles of immobilization ddY mice models induced by right side sciatic nerve neurectomy, the cross sectional histological profiles of the muscularis (M) gastrocnemius, M. tibialis cranialis and M. tibialis caudalis were observed after 28 days of treatment of massages with the changes of body weight, thickness of hind limb and individual muscle weights. In addition, changes of serum aspartate amino- transferase (AST) and creatine phosphokinase (CK) levels were also demonstrated with diameter of individual muscle fiber and muscle fasciculata, and number of muscle fiber in each of three types of muscles located in the calf. The experimental groups were divided into five groups, 1) Sham-operated group (Sham), 2) Neurectomized but not massage control group (Control), 3) Neurectomized and massage at knee joint regions (T1), 4) Neurectomized and massage at calf regions (T2), and 5) Neurectomized and massages at achilles tendon regions (T3). The experimental animals were used 5 per groups. The results are as follow: 1. No significant changes of body weight were demonstrated in this groups during whole experimental periods compared to that of Sham group. In addition, no significant changes of body weight gains during experimental periods (Day 0 - Day 27: 28 days of treatment) were also observed. 2. The thickness of intact left side hind limb was not changes in all tested groups compared to that of Sham group. However, the thickness of right side hind limb were remarkedly decreased in Control, T1, T2 and T3 groups compared to that of Sham group. In addition, the differences of thickness of hind limb between right and left sides were also significantly increased in Control and massage groups (T1, T2 and T3) compared to that of Sham group. However, the thickness of right side of hind limb were significantly increased and the differences of thickness between both sides of hind limb were dramatically decreased in massage groups compared to that of Control group in followed order: T1 > T3 > T2. 3. Absolute and relative weight of M. gastrocnemius in the intact left side of hind limb was not changes in all tested groups compared to that of Sham group. However, the weight of right side M. gastrocnemius were remarkedly decreased in Control, T1, T2 and T3 groups compared to that of Sham group. In addition, the differences of weight of M. gastrocnemius between right and left sides were also significantly increased in Control and massage groups compared to that of Sham group. However, the weight of right side M. gastrocnemius were significantly increased and the differences of weight between both sides of M. gastrocnemius were dramatically decreased in massage groups compared to that of Control group in followed order: T3 > T1 >. 4. Absolute and relative weight of M. tibialis cranialis in the intact left side was not changes in all tested groups compared to that of Sham group. However, the weight of right side M. tibialis cranialis were remarkedly decreased in Control, T1, T2 and T3 groups compared to that of Sham group. In addition, the differences of weight of M. tibialis cranialis between right and left sides were also significantly increased in Control and massage groups compared to that of Sham group. However, the weight of right side M. tibialis cranialis were significantly increased and . the differences of weight between both sides of M. tibialis cranialis were dramatically decreased in massage groups compared to that of Control group in followed order: T3 > T1 > T2. 5. Absolute and relative weight of M. tibialis caudalis in the intact left side was not changes in all tested groups compared to that of Sham group. However, the weight of right side M. tibialis caudalis were remarkedly decreased in Control, T1, T2 and T3 groups compared to that of Sham group. In addition, the differences of weight of M. tibialis caudalis between right and left sides were also significantly increased in Control and massage groups compared to that of Sham group. However, the weight of right side M. tibialis caudalis were significantly increased and the differences of weight between both sides of M. tibialis caudalis were dramatically decreased in massage groups compared to that of Control group in followed order: T3 > T1 > T2. 6. A significant increase of serum AST levels were demonstrated in Control group. However, serum AST levels of massage groups were significantly decreased compared to that of Control group in followed order: T3 > T1 > T2. In case of 73 group, the values decreased into similar levels compared to that of Sham group. 7. A significant increase of serum CK levels were demonstrated in Control group. However, serum CK levels of massage groups were significantly decreased compared to that of Control group in followed order: T3 > T1 > T2.

  • Background: Tapered grafts, which have a smaller diameter on the arterial side, have been increasingly used for arteriovenous fistula (AVF) formation. We compared the outcomes of 4-6-mm tapered and 6-mm straight forearm loop arteriovenous grafts. Methods: A total of 103 patients receiving forearm loop arteriovenous grafts between March 2005 and March 2015 were retrospectively analyzed and separated into 2 groups (group A, 4- to 6-mm tapered grafts, n=78; group B, 6-mm straight grafts, n=25). In each group, complications and patency rates after surgery were assessed. Results: Clinical characteristics and laboratory results, except for cerebrovascular disease history (group A, 7.7%; group B, 28.0%; p=0.014), were similar between the groups. No significant differences were found for individual complications. Kaplan-Meier survival analysis revealed no significant differences in 1-year, 3-year, and 5-year patency rates between groups (61.8%, 44.9%, and 38.5% vs. 62.7%, 41.1%, and 35.3%, respectively). Conclusion: We found no significant differences in complication and patency rates between the tapered and straight graft groups. If there are no differences in complication and patency between the two graft types, tapered grafts may be a valuable option for AVF formation in light of their other advantages.

  • The objective of this study was to examine the effects of auditory biofeedback training and kicking training on walking times in patients with hemiplegia to determine if the effects of such training would be maintained even after stopping the intervention. Thirty hemiplegia patients were selected and randomly assigned to a control group of 10 patients to receive general exercise treatment; an auditory biofeedback training group of 10 patients to receive auditory biofeedback training, along with general exercise; and a kicking training group to receive kicking training, along with general exercise. All the patients received their respective training 12 times in total, three times per week for four weeks. In addition, all those in the control and experimental groups received the same general exercise treatment 12 times in total, three times per week for four weeks, and underwent follow-up tests thereafter. The patients' 10m walking times were measured using a stopwatch. The significance was analyzed using repeated-ANOVAs. In cases where there were interactions between measuring times and groups, in each group were examined using repeated-ANOVAs. In cases where there were differences, post-hoc tests were conducted using repeated of contrast test. The 10m walking times of the control and experimental groups were significant differences in 10m walking times were shown between measurement times(p<.05), and significant differences in the interactions between measuring times and groups were shown between the groups(p <.05). However, no significant differences in 10m walking times were shown between the groups(p>.05). The auditory biofeedback training group showed significant decreases in walking times four weeks after the beginning of the intervention(p<.05) and significant increases eight weeks after the beginning of the intervention(p<.05). The kicking training group showed significant decreases in walking time four weeks after the beginning of the intervention(p<.05) and maintained the walking times without showing any significant differences eight weeks after the beginning of the intervention(p>.05). The walking speeds of only the kicking training group were maintained until eight weeks after the beginning of the intervention.

  • Purpose: The purpose of this study was to compare parenting stress between married migrant women and Korean women. Methods: Subjects were 68 married migrant women and 70 Korean women raising children aged seven years or younger, living in three different cities in Gangwon Do. To measure parenting stress, we used Kim's (1997) questionnaire that had been modified from Richard & Abidin's (1990) Parenting Stress Index (PSI). Results: There were significant differences between the two groups in age, academic credentials, job, monthly income, and achievement of maternal role. No statistically significant differences were found for parenting stress scores (p<.355), but there was a significant difference in the child characteristics of parenting stress (p<.007) between the two groups. There were no differences in the demographic variables influencing parenting stress between the two groups. Conclusion: The development of multi-cultural parenting and family support programs should consider the nationality and marital satisfaction of the family.

  • Purpose : The purpose of this study was to demonstrate the effects of lumbar stabilization exercise on static and dynamic balance performance with unstable supporting surface and an even surface. Methods : The subjects of this experimental study were 30 patients among hospitalized stroke patients. They were randomly divided into two groups: unstable supporting surface group(USS; n=15) and an even surface group(ES; n=15). The lumbar stabilization exercise program for patients in two groups went through 40 minute exercise sessions three times a week for 8 weeks. To analyze the effects of a variety of supporting surface, Functional reaching test(FRT), Berg's balance scale(BBS), and Overall stability index(static balance) were measured before and after the exercise. The paired t-test was used to compare mean differences between before and after exercis and the independent t-test was used to compare mean differences between groups. Results : After 8 weeks exercise program, there were significant differences between before and after exercise in FRT, BBS, and static balance. But there were not significant differences in balance between two groups. Conclusion : This study suggest that lumbar stabilization exercise on unstable supporting surface and an even surface can improve FRT, BBS, and a static balance.

  • The purposes of this studs were 1) to identify web navigation values and classify consumers based on these values and 2) to determine differences between consumer groups and between types of shopping mall in evaluation of website attributes when shopping apparel. The data were collected via a self-administered questionnaire from 204 male and female students who experienced shopping at the website, living in Cheju and analyzed by factor analysis, cluster analysis and t-test. Two factors of navigation value were found and labeled as; information value and entertainment value. Two groups were identified based on navigation value; users of information value (53%) and users of entertainment value (47%). Significant differences between two groups were found in evaluating website attributes selling products of various types regarding apparel products and processes for information search, order and payment. However, for shopping mall website selling only apparel products, differences between two groups were not significant in evaluating most attributes except for two items to evaluate apparel products. Differences between shopping mall types (shopping malls selling products of various types and selling only apparel product) were significant in evaluation of internet users of information value regarding attributes of apparel products while differences between shopping mall types were not significant in evaluation of users of entertainment value regarding all attributes. Internet users of information value showed favor to shopping mall website of department store type chi e internet users of entertainment value showed favor to shopping mall website selling only apparel products.
