Purpose : This study investigated the effect of 4 weeks training of virtual reality game on balance and gait ability, depression of elderly people. Methods : The subjects of this study were 12 elderly people over 65 age. The subjects were treated by training using virtual reality gam (during 60 minutes, 3 times a week for 4 weeks). The results of the experiment were analyzed using paired T-test along with averages and standard deviations as the statistical methods for data analyses. Results : In comparison of depression, gait and balance ability between pre-test and post-test, there were statistically significant differences. Conclusion : Our study finding indicate that training using virtual reality game could improve balance and gait ability, depression in elderly people. According to our study, training using virtual reality game is judged to be used for elderly people with gait and balance problems, depression to prevent fall down.

The digital age start in earnest with the widespread use of the Internet. As a digital product, virtual idols bring new value to the design and dissemination of commercial brand images. "Luo Tianyi" is the world's first avatar and VOCALOID voice bank of Chinese. It has a large number of fans in China and is widely used in brand promotion. Therefore, "Luo Tianyi" is taken as the research object. Initially, we investigated the virtual idols through books, literature on the internet and other materials. Then we discussed semiotics and theories related to culture code brand design methodology (CCBD). After that, putting the above theories into practice, combined with brand design cases, we analyzed the strategy of virtual idols in brand promotion and dissemination, at last, we have the conclusion as followed. The results show that the virtual idols, visual symbol of "Luo Tianyi" can express the Index and Symbol corresponding to the brand information according to the characteristics of the brand. As an image of cultural code, "Luo Tianyi" can present three visual images at the same time, which are contemporary, traditional and future. In addition, these three visual images are presented in a strong and weak combination, which has a positive impact on the visual communication of the brand.

A study using 3D virtual garment simulation is carried out for the evaluation and application on the pants fit for obese women in their age of 20s and 30s. The results are as follows; 5 obese women in their 20s and 30s were selected for the testing 3D body. They showed no significant differences in all items, comparing with the data of 5th Size Korea body dimensions. The average waist circumstance of the subjects' 3D body dimensions was 87.0cm, hip circumstance was 102.4cm, BMI was $27.1kg/m^2$, and their obese body types had similar mean values. Based on the detailed design of ready made pants and the study results of 20~30s obese women preference for pants design, pants of straight silhouette and semi-tight fit which have waist line lowered, no front dart and one back dart, were manufactured with 100% black cotton and cotton spandex mixed fabrics. When comparing the appearances between real garment and virtual garment, the average of the real garment with 100% cotton was 3.70 and the virtual garment was 4.05. The average of real garment with cotton spandex mixed fabrics was 3.75 and the virtual garment was 4.06. Therefore, the average of virtual garment was highly evaluated. When comparing the results of evaluating the appearance, there was no significant difference caused by materials between real garment and virtual garment. The expression for the ease of virtual garment and real garment was also similar for good evaluation. Thus, 3D virtual garment simulation did positively prove its reliability and effect.

There are many spreading effects that never experienced before due to digital progress of the present age. Digital progress produce innovative changes now in cultural environment, architectural process, exhibition techniques, called the age of digital technology. The functional relation between 'Digital' and' Architecture' must not to be overlooked in field of cyber architecture, further more, space design, so that requests some necessary to build new paradigm for digital presentation and spatial experience.

Purpose : The purpose of this study was to investigate the effects of virtual exercise training programs on the improvement of balance in the elderly women. Methods: The subjects were fifteen female citizens, 67 years of age or older living in G city, the subjects were randomly divided into groups; Virtual exercise training group(n=9), control group (n=6). After treatment measured balance by Berg Balance scale test and One-leg stand test during virtual exercise training program at pre-intervention and post-intervention. Results : The results of this study were as follows : Virtual Exercise Training Program (Wii fit) after applying the Berg balance test scores and One-Legged Stance Test, the evaluation results showed significant results(p<05). Conclusion : Virtual exercise training programs can be used to improve the balance of the elderly, as it has been shown to increase Berg balance test and one-leg stand results conducted after virtual training programs. Virtual Exercise Programs(Wii fit) were applied to demonstrate the effecting the balance of the elderly to promote more research on the impact of the ADL survey.

본 논문에서는 현실세계의 사용자와 주변 환경의 컨텍스트를 이용하여 가상환경과 상호작용하는 컨텍스트 기반 분산 갸상 환경 시스템을 제안한다. 제안된 시스템은 컨텍스트를 이용변경, 공유함으로써 다음과 같은 특징을 갖는다. 첫째, 가상환경의 응용서비스는 사용자의 신원, 연령, 언어 등의 컨텍스트에 따라 가상 환경을 제어하기 위한 인터페이스를 변경함으로써 개인화된 상호작용 환경을 보장한다. 둘째, 가상 환경에 있는 대상물을 제어하는 사용자의 입력 장치 신호를 컨텍스트 정보로 추상화함으로써 사용자가 다른 가상 환경 시스템으로 이동하여도 동일한 입력 장치를 가지고 해당 대상물을 제어할 수 있는 가상 환경과 장치의 적응적 접근성(adaptive access)을 보장한다. 마지막으로 분산 가상 환경 시스템들은 가상환경 변화에 대한 컨텍스트를 공유하여 이기종의 가상 환경 시스템 사이에서 발생하는 데이타 표현의 불일치성을 제거함으로써 이기종 분산 가상 환경 사이의 효과적인 동기화 메카니즘(synchronization)을 제공한다. 따라서 CIVE는 원격회의, 게임, 가상문화 관람 등과 같이 짐차 보편화되고 있는 가상환경 응용분야에서 활용될 수 있다.

뇌기능 장애 환자에서 자세균형 제어능력의 저하는 보행 및 일상생활동작 수행 등에 어려움을 초래하며 이에 대한 정확한 평가 및 치료를 위하여 일상의 환경변화와 유사한 상황을 제공하고 이에 따른 자세균형 조절 능력을 파악하는 것이 중요하다. 본 연구는 뇌기능 장애 환자에서 가상적 움직이는 환경에 따른 자세균형 조절 기능을 정확히 평가하고 환경의 움직임이 자세균형 조절에 미치는 영향을 분석하였다. 15명의 뇌기능 장애 환자들과 정상인 15명을 대상으로 실생활과 유사한 환경의 조성을 위하여 HMD를 이용한 가상 환경 움직임(Virtual Moving Surround)을 네 가지 다른 패턴으로 제공하였다. 자세동요의 정도는 힘판을 이용하여 신체압력중심의 변화를 전체이동거리, 동요주파수, 최대 빈도 COP 위치로 측정하였으며 가상 환경의 차이에 따른 변화를 비교 분석하였다. 연구결과 검사 재검사 신뢰도평가에서 일관된 분석결과를 나타냈고 뇌 기능장애 환자와 정상인의 분석에서는 두 그룹간의 차이를 확인할 수 있었다. 특히 전후로 빠르게 변하는 가상 환경에서 가장 큰 자세동요를 나타내었고 통계적으로 유의한 차이가 있었다. 본 연구를 통해 뇌기능 장애 환자에서 가상 환경 변화가 자세균형 조절에 미치는 영향을 확인할 수 있었으며 이러한 환자들을 위한 치료와 평가 환경 조성 등에도 유용한 자료로 쓰일 수 있을 것으로 사료된다

Virtuality is a product of the information age, and as it plays a larger role in the activities of individuals, groups and organizations, the issue of how human behavior varies between virtual and physical space has become one of the most important questions facing the management environment of today. The purpose of this article is to examine how virtuality shapes individuals' social relationships within and outside their work groups. We developed a conceptual framework that explores the links between virtuality and social network based on computer-mediated communication theory and social network theory. Using data from 172 individuals of 42 project teams in 5 global business consulting firms, we tested cross-level hypotheses. The results of hierarchical linear modeling (HLM) indicate that virtuality significantly influences individual's internal tie strength as well as external bridging ties. The results also show the effects of virtual process via CMC vary along with the virtual context.

본 연구는 시뮬레이터 멀미 측정 도구인 SSQ를 이용해 가상현실 멀미를 유발시키는 지수를 도출하여 각 증상별로 심각도를 진단함으로써 가상현실 멀미를 위한 측정 방식을 제시하였다. 그래서 본 연구는 기존 가상현실 콘텐츠에서 주로 사용하는 1인칭, 3인칭게임 및 $360^{\circ}$ 실사 콘텐츠를 이용했고 SSQ를 이용하여 다양한 멀미 증상을 측정하였으며 통계분석을 통해 산출한 결과는 가상현실 멀미 증상을 완화하는데 기여하고자 한다. 또한 본 연구에서는 성별, 나이, 경험유무에 따라 가상현실 멀미에 차이가 있는지에 대해서도 통계방법론을 이용해 입증하였다.
