This study aimed to investigate the effects of the virtual reality simulation for malocclusion examination for dental education. A 4-step modeling procedure was applied to develop a tooth model with a realistic level in order to be held and observed in detail. Eighty-six participants used HMDs to examine the developed virtual dental simulation to identify their perception according to expertise levels. The independent variable, expertise group, included three levels: 29 juniors, 29 seniors, and 28 dentists, respectively. The dependent variables, that were task-load and usability, were measured through two cases. Results showed that the junior group perceived a higher level of mental demands and embarrassment than the dentist group. It indicated that the perceived task load varies according to the expertise levels in the simulation task. However, the senior group perceived a higher level of ease of use than the dentist group. This study presented the implications for the development of virtual reality simulation in detail.

Purpose : This study was performed to evaluate the effects of virtual reality combined robot assist gait training (VRG) on improvement of balance and respiratory function in chronic stroke patients. Methods : A single-blind, randomized controlled trial (RCT) was conducted with 35 chronic stroke patients. They were randomly allocated 2 groups; VRG group (n=18) and conservative treatment group (CG; n=17). The VRG group received 30 minutes robot assisted gait training combined virtual reality training, robot assisted gait training was conducted in parallel using a virtual reality device (2 sessions of 15 minutes in a 3D-recorded walking environment and 15 minutes in a downtown walking environment). In the conservative treatment group, neurodevelopmental therapy and exercise therapy were performed according to the function of stroke patients. Each group performed 30 minutes a day 3 times a week for 8 weeks. The primary outcome balance and respiratory function were measured by a balance measurement system (BioRescue, Marseille, France), Berg balance scale, functional reach test for balance, Spirometry (Cosmed Micro Quark, Cosmed, Italy) for respiratory function Forced vital capacity (FVC), forced expiratory volume in 1 second (FEV₁), and maximum expiratory volume (PEF) were measured according to the protocol. The measurement were performed before and after the 8 weeks intervention period. Results : Both groups demonstrated significant improvement of outcome in balance and respiratory function during intervention period. VRG revealed significant differences in balance and respiratory function as compared to the CG groups (p<.05). Our results showed that VRG was more effective on balance and respiratory function in patients with chronic stroke. Conclusion : Our findings indicate that VRG can improve balance and respiratory function, highlight the benefits of VRG. This study will be able to be used as an intervention data for recovering balance and respiratory function in chronic stroke patients.

Purpose : This study aimed to understand the influence of the virtual reality program combined with cognitive activity on elderly people's balance ability. Method : We randomly divided 14 elderly people receiving daytime protection service from D daytime protection center for senior citizens located in Busan-si into a group(seven) with cognitive activity combined with virtual reality program, and the other group(seven) with only virtual reality program. In order to compare the balance ability before/after the therapeutic intervention, the Berg Balance Scale was carried out. The Mini-Mental State Examination-Korea(MMSE-K) was also conducted to compare their cognitive functions. Result : Both groups showed statistically significant differences in balance ability before/after the therapeutic intervention(p<.05) while there were no statistically significant differences in balance ability after the therapeutic intervention(p>.05). The cognitive functions before/after the therapeutic intervention were not statistically significantly different in both groups(p>.05). Conclusion : The findings showed that the application of virtual reality program combined with cognitive activity could improve elderly people's balance ability. It is considered that the application of virtual reality program can have positive influence on the improvement of elderly people's balance ability, as an intervention method for improving balance ability in the future.
