Objective : The purpose of this study was to investigate the effect of virtual reality program on fall efficacy and activities of daily living(ADL) for patients with stroke. Method : Twenty stroke patients were participated voluntarily and were assigned randomly into the control and the experimental groups. Both control and experimental groups were given same basic rehabilitation treatment while only the experimental group was given virtual reality program. The fall efficacy of both groups was assessed using fall efficacy scale(FES) and ADL performance ability was assessed by functional independence measure(FIM). Result : Fall efficacy and ADL performance ability showed a statistically meaningful difference for both experimental and control groups(p< .05), the fall efficacy and ADL performance ability of the experimental group improved meaningfully in a statistical way than that of the control group(p<. 05). Conclusion : It was found that carrying out virtual reality program with occupational therapy has an effect on fall efficacy and ADL performance ability of patients with stroke. Therefore, virtual reality program can be a way of treatment for patients with stroke to improve their fall efficacy and ADL performance ability, and the program can also be applied in clinics as well as occupational therapy.

The purpose of this study was to investigate effects of North Korea defectors' living experiences in South Korea on their self-perceptions and perceptions of South Korea. For this purpose, a questionnaire was distributed to 66 defectors with no living experiences at all and 99 defectors with living experiences of an average of 2.7 years in South Korea. They were asked to rate their own as well as South Koreans' values, personality, attitudes toward sexual misbehavior, gender stereotypes. Also, they evaluated the society of South Korea and its political control. The results indicated that those defectors with living experiences tended to perceive more negatively their own and South Koreans as well, and yet that they were less negative for sexual misbehavior and weaker for gender stereotypes. Also, results suggested that living experiences led defectors to perceive South Korea in a more negative way. Those findings were discussed in terms of changes in culture.

This study was designed to test the convergence effectiveness of virtual reality programs for patients with stroke by using meta-analysis. Based on the PICOS criteria, we searched domestic literature and selected the final 9 studies in relation to 'stroke' and 'virtual reality programs'. Evaluation of the risk of bias in individual studies was conducted using evaluation tools according to the design of each study. The effect size of the meta-analysis was calculated using CMA program. The mediating effect analysis was conducted by sub-group analysis and meta-regression analysis. The overall effect size of the virtual reality program on the activities of daily living ability was Hedges's g=0.302(95% CI: 0.064~0.540), Therefore, virtual reality programs can increase the activities of daily living in stroke patients and have a positive impact on the medical industry that the convergence of virtual reality industry and healthcare industry.

The purpose of this study was to verify the clinical usefulness of the virtual reality rehabilitation system which Academic-Industrial cooperation develop through clinical experiment for recovering the functional abilities in stroke. For this purpose, 24 Stroke(hemorrhage13, infarction11)participated in a clinical experiment. They were randomly assigned to the virtual reality rehabilitation system group(n=13) and conventional rehabilitation training(Activities of daily living, cognition training, motor control) group(n=11). All participant were evaluated with three standardized assessment tools(Functional Independent Measure; FIM, Mini-Mental State Examination for Korean; MMSE-K, Self-esteem scale) before and after the planned intervention sessions. All participant were intensively carried out for 8weeks, 3times a week. The results were as follows. The experimental group showed significant improvements for Activities of daily living, basic cognitive abilities and self-esteem related with life satisfaction after the interventions(p<.05). There were no significant differences between two groups for all assessment tool after interventions. Because of this experimental results, the virtual reality rehabilitation system showed the clinical utility for recovering the function in stroke. Further studies are needed to verify the clinical usefulness on the improvement of various functions in brain injury and dementia.

Objective : The purpose of this study was to investigate the effects of virtual reality-based activities of daily living (ADL) training on ADL and rehabilitative motivation in patients with traumatic brain injury. Methods : This study was performed using a pre-post design with seven traumatically brain injured patients. Subjects were subjected to virtual reality-based ADL training for 30 minutes a day, 2 to 3 times a week for 4 weeks. Evaluation was conducted before and after the intervention using the Korean Modified Barthel Index (K-MBI), Cognitive Functional Independence Measure (C-FIM), and Volitional Questionnaire (VQ). Changes before and after intervention were analyzed by Wilcoxon signed-rank test, and correlations were analyzed using Spearman's coefficient. Results : After intervention, patients with traumatic brain injury showed significant improvements in K-MBI (p<.05). There was no significant change in total C-FIM score and VQ score (p>.05). Total C-FIM score correlated significantly with VQ score (p<.05, r=.755). The social cognition domain of C-FIM had a significant correlation with VQ score (p<.05, r=826). Conclusions : Virtual reality-based ADL training can improve ADL performance, but further research is needed to determine whether improvements in social cognition and rehabilitative motivation are possible.

메타버스는 가상, 초월을 의미하는 '메타'(meta)와 세계, 우주를 의미하는 '유니버스'(universe)를 합성한 신조어이다. 메타버스는 기본적으로 가상의 세계이다. 그러나 향후 현실과 메타버스가 공존한 세상에서 태어나 성장할 아이들에겐 메타버스 자체가 현실의 일부이고 메타버스를 통한 소통과 사회활동이 일상이 될 것이다. 메타버스 안에서 학습, 놀이, 휴식, 경제활동 등 일상의 모든 현실과 연속성을 띠고 소통하면서 가상세계의 나와 현실의 내가 직접적인 영향을 주는 세상이 될 것이다. 이 기술들을 인간 생활에서 가장 중요한 부분일 수 있는 커뮤니케이션 활성화에 활용하기 위해서는 기술과 인간에 대한 많은 고민과 연구가 필요할 것으로 보인다.
