The elderly people with advancing years have many problems such as the decline of the proprioceptive, visual & vestibular function and muscle weakness. Furthermore the decrease of the reflex which influences the balance ability in sudden change of the movement could cause the falls. The difficulty of the balance caused by the fear releated to the fall aggravates the Falls Efficacy and causes a lot of the disability of the independent activities of daily living. The purpose of this study was the effect of a Virtual Reality Program on Static Balance control and Fall efficacy of Elderly people. 14 elderly people(subjects) who were ≥65years of age partiripated in this study and they were divided into VR(Virtual Reality) group(n=7) and Control group (n=7). VR group took the general physical therapy & IREX and only the general physical therapy was carried out in the control group. VR group of intervention was carried out for 30min. total 8times. They were evaluated by BIO-Rescue, Fall Efficacy Scale before and after treatment. The Static Balance control and Fall efficacy were assessed by Bio-Rescue & Falls Efficacy Scale. The analysis of the resulf was assessed by Wilcoxon signed test & Mann-Whitney U test. The result showed that the static balance of VR group with the open eyes was improved in a static balance test and range of the movement was increased in limited of stability. And Falls Efficacy was also efficacious. IREX was effective to static balance control and Falls Efficacy of the elderly When we think about these effects, various treatments and objective assessments using VR program will be needed for the elderly

The purpose of this study was to determine the effect of mechanical horseback riding training on trunk control, balance function in stroke patients. 15 stroke patients were recruited for this study. The subjects were randomly assigned to two groups: experimental(n=7) and control(n=8). All subjects received a routine physical therapy. The mechanical horseback riding training was for 30 min in the case of the EG subjects. This study was carried out approximately 8 weeks from March 4 to May 3. The assessment tools of this study involved the trunk control test, postural assessment scale for stroke, Berg balance scale and timed up and go test. The measurements were recorded before the intervention and after the intervention. In the cases of the EG subjects and CG subjects, the variables measured after the intervention significantly differed from trunk control test, postural assessment scale for stroke, Berg balance scale and timed up and go test before the intervention (p<.05). Also, there were significant differences in trunk control test, postural assessment scale for stroke, Berg balance scale and timed up and go test at post test between the 2 groups (p<.05). The findings indicate that mechanical horseback riding training exerts a positive effect on trunk control, balance function in stroke patients. Further studies are required to generalize the result of this study.

Objectives: To find evidence that sleep is necessary for normal brain function, thus indicating that declines in both sleep quality and quantity are related to worse performance of many daily tasks and deteriorated physical functions. The present study investigates the relationships of balance control and reaction time with sleep quality. Methods: 58 healthy (male 20, female 38) volunteers with informed consent participated in this study. The Self-reported Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality and relevant factors, and the subjects were divided into groups A (PSQI < 5) and B ($PSQI{\geq}5$) based on this index. Static balance control and reaction time to visual stimuli were conducted to assess their relationship with sleep quality. Results: Group B exhibited excessive daytime sleepiness significantly more often compared to group A. Static balance control did not markedly change relative to sleep quality, but reaction time and error to visual stimuli were significantly increased in group B compared to group A. Conclusion: These findings indicate that a decline in sleep quality can result in delayed reactions, as well as decreased accuracy of these reactions. They also suggest that low sleep quality may be associated with changes in physical functions, including balance control through reduced selective attention.

In this study, we analyzed the effects of game-based visual feedback training on postural balance control in young adults. We provided postural balance training for four weeks in fifth minute a day and three days a week using training system of postural balance based forceplate. We evaluated the ability of postural balance using balance SD(Biodex, medicalscience Inc., USA) for the validation of game contents based visual feedback training program. The results showed that postural stability and limits of stability were improved significantly before and after the training(p<0.05). Our study indicates that postural balance training of visual feedback based game could be adapted for improving postural balance. Also, for application of this game-based visual feedback training in older adults, we could develope of various game contents for disease types and conduct quantitative analysis and data collection of postural balance in the aged.

The Purpose of This study is amid competition, High-quality human resources in food service industry make a lot of efforts. Especially, Work and Life Balance(WLB) is a considerable factor when modern workers decide and maintain the workplace and also it could be supposed as one strategic method that corporations could attract and maintain talented people. This study built a exploratory model that there is causal relationship of WLB(work and life balance) to employee's organizational commitment. Additionally this study examine the Moderating Effect of perceived value of work between WLB(work and life balance) and organizational commitment. This study utilized total 217 responses from workers of food service industrial employees and as analysis methods, it used descriptive statistic analysis, correlation analysis, multiple regression analysis, and hierarchical analysis.

We examined the moderator roles of negative belief in emotional expression and emotional clarity between work-life balance and psychological symptoms (depression, anxiety and somatization). Also we identified gender differences in their moderating effects. This study was based on a sample of 869 married working employees (man: 424, women: 445). Hierarchical moderated regression analyses showed that work-life balance, negative belief in emotional expression and emotional clarity were strongly associated with depression, anxiety and somatization. While negative belief in emotional expression significantly moderated the relationship between work-life balance and depression and anxiety, emotional clarity showed no significance. We found gender differences in moderating effects of two moderators. In specific, the only women who had more negative belief in emotional expression were more psychological symptoms in a low work-life balance situation. On the other hand, the only men who had higher emotional clarity were less depressive and anxious under the conditions of high work-life balance. We discussed about implications of these results.

The purpose of this study is to assess the ability of balance control in virtual moving surround stimulation using head mount display (HMD) device and force platform in patients with brain injury. Fifteen patients with stroke (mean age 54.47 yrs) and fifteen healthy normal persons participated. COP parameters were obtained total path distance, frequency of anterior-posterior and medial-lateral component by FFT analysis, weight-spectrum analysis in the two different conditions; (1) during comfortable standing with opened or closed eyes, (2) during virtual moving surround stimulation delivered using HMD with four different moving pattern. Moving patterns consisted of close-far, superior-inferior lilting (pitch) , right-left tilting (roll) and horizontal rotation (yaw) movement. In all parameters, the test-retest reliability was high. Also, the construct validity of virtual moving surround stimulation was excellent (p＜0.05). A posturographic balance assessment system equiped with virtual moving surround stimulation using HMD is considered clinically useful in evaluation of balance control in patients with brain injury.

In this study, we examined the impact on balance ability and jump performance of soccer players with functional ankle instability using virtual reality based neuromuscular posture control fusion training. Soccer players were divided into 15 people of virtual reality-based neuromuscular posture control fusion training group and 15 people of common treadmill training group and performed for 30 minutes three times a week for 8 weeks. In order to evaluate the balance of ability, using biorescue, it measured surface area, whole path length, limit of stability. In order to measure jump performance, it measured counter movement jump with arm swing and standing long jump. The results showed the statistically significant difference in the balance comparison of surface area, whole path length, limited of stability and the jump performance comparison of counter movement jump with arm swing, standing long jump. As a result, virtual reality-based neuromuscular posture control fusion training was found to be more effective to improve its balance ability and jump performance than common treadmill training.

This study was designed to verify that the positive relationship between career management behavior and turnover intention is mediated by employability. Futhermore, investigation whether work-life balance and communication climate moderate this relationship was also the purpose of this study. The results from 300 office workers younger than 34 that (1) employability mediated the relationship between career management behavior and turnover intention, (2) the moderating effect of work-life balance about mediating effect of employability was not statistically significant, but when the level of work-life balance was high, the relationship between employability and turnover intention was reinforced, (3) the moderating effect of communication climate against mediating effect of employability was not statistically significant, and the moderating effect of communication climate between employability and turnover intention was also not found. Based on this non-intuitive results, researcher offered new interpretation which can be acquired from rejections of hypotheses, implications, limitations, and the proposal for future research.
