This study is a systematic review study to confirm the characteristics, effects, and application strategies of domestic and foreign virtual reality programs provided by dementia education. This study is based on the literature published up to July 2020, CINAHL, Cochrane, EMBASE, and Pubmed electronic databases were used overseas, and RISS, KISS, and DBpia were searched in Korea. Based on the selection criteria and exclusion criteria, the final six papers were used for analysis. As a result of the analysis, the subjects of the selected literature were two informal caregivers (33.3%), one general (16.7%), and three students (50.0%) including nursing students and medical and pharmacy students. The virtual reality program was effective in a total of five areas(empathy ability, dementia attitude including knowledge and comfort of dementia, trust in own abilities, dyadic relationship scale), of which 75% of the studies measured empathy ability had significant effects. The results of this study confirm that virtual reality technology can be used for human-centered nursing based on empathy.

This study applied virtual reality to women health nursing practicum for nursing students and analyzed the educational effect on meta-cognition and critical thinking. The study design was a convergent mixed method using single-group pre-post test design and individual in-depth interviews. After applying the virtual reality program, the post-score (104.16±12.98) was statistically significantly higher than the pre-score (98.59±18.09) (t=1.85, p=.030). There was no statistically significant difference in critical thinking after the program, with the post-score of 101.66±7.18 and the pre-score of 99.18±15.13 (t=1.00, p=.108). Therefore, women health nursing practice education using virtual reality can help improve the meta-cognition of nursing students.

Computerized 3D virtual dental models are currently available, and their use has started to improve treatment outcomes. The accuracy of digital models has been demonstrated by many studies and various intra-oral scanners are innovated for short scanning time and high precision. Recently, a digital model was combined with a high technology computer-driven system, which was developed for the application of a digital set-up and indirect bonding of lingual attachments. In this section, virtual treatment planning using a virtual set-up program is be introduced, and the clinical applications and accuracy of computer-generated indirect bonding are discussed.

The paper describes system design of next-generation Ship Simulator using Virtual Reality (VRSS), well known as human-computer interaction. VRSS system is required to have special condition that comprises multiple user participants such as captain, officer, pilot, and quartermaster. To cope with that condition, core technologies were explored and proposed multi-networking system with broker server. The evaluation of the proposed system was done with PC-based immersion-type VR device, constituted with HMD (Head Mounted Display), Head Tracking Sensor, Puck, Headphone, and Microphone. Using the VR device, assessment test was carried out in a virtual bridge with 3D objects, which are created by VRML (Virtual Reality Model Language) program. As results of tests, it is shown that the cybernetic 3D objects were act as if real things in a real ship's bridge. Therefore, interesting interaction with participants can be obtained in the system, Thus, we found that the proposed system architecture can be applicable to VRSS system construction.

This paper introduces a practical implementation of virtual crowd simulation software. Usual commercial crowd simulation softwares are complex and have program-like script interfaces, which makes an animator hard to learn and use them. Based on the observations that most crowd scenes include walking, running and fighting movements, we have implemented a crowd simulation system that automatically generates movements of virtual characters given user's minimal direction of initial configuration. The system was implemented as a plug-in of Maya which is one of the most commonly used 3D software for movies. Because generated movements are based on optically captured motion clips, the results are sufficiently natural.

In this paper force feedback control system is investigated for improving the quality of the haptic feedback in virtual reality applications. We suggested the method of controlling the haptic device and modelling the virtual environment. Haptic device is composed of five bar link structure, voice coil motor, control board, and virtual environment modeling program. We applied voice coil motor in the actuating system for simple structure and easy control. Virtual environment modelling is constructed in PC, and the control signals of the actuators and the encoder data are transferred to the control system through USB. Experiment is performed to evaluate the characteristics of the haptic device.

This research explored the impact the thoughts and opinions of lecturers teaching university general English courses have on their virtual classes and discussed the differences and similarities in their perspectives. As a research methodology, the Q-method was used, which usually consists of five steps: Q-population, Q-statements, Q-participants, Q-sorting, and factor analysis using PQMethod, a computer software program. A total of 30 statements were finally selected and 26 people directly involved in teaching online university general English courses were selected as participants in this study. Based on the results of the factor analysis, this research discovered three different factors, which were interaction & content-oriented, online teaching favored, and content-oriented. The results of this study can contribute to developing the future directions of virtual university general English classes to help learners improve their English skills and prepare lecturers for the future.

This paper show that, without installation of expensive VR (Virtual Reality) program, the sharing information is possible through posting three-dimensional road structures on the web, and avoiding the conventional top-down decision making method, fast bottom-up communication is possible base on the Virtual GIS (Geographic Information System). In this paper, using Viewpoint Scene Builder, internet-based software, the transformation was conducted to give pertinent type for web posting. In order to use the completed route at the scene builder, the output with ASCII Export is required, and ASE (ASCII Scene Export) contains the property information including the coordinate and frame of mesh vertex. Through in advance recognition of the problems regarding route design and petition due to environmental rights infringement, the time and cost due to design alteration can be reduced. It's difficult to provide VR based on the internet because file that embodied with internet GIS was complicated and its capacity comes to scores of mega-bites. But, this study provides VR with internet according to a basis by simplification of files.

In the era of 'Untact', virtual reality-based job training platforms are actively being used as part of non-face-to-face education for students with developmental disabilities. Because the people with developmental disabilities may lack sufficient cognitive abilities, it is difficult to conduct untact training seamlessly without the help of a third party. Therefore, it is necessary for training programs to identify the right timing to provide help so that the training can be continued. This research analyzed the visual attention of students with developmental disabilities in virtual reality-based job training program in order to determine the point of time when an intervention is required by the trainee. Results showed that students who completed the mission tended to have intense visual attention on a small number of objects for a certain period of time; the visual attention of the students who failed tended to shift erratically among multiple objects.

Purpose: This study aimed to develop 360° virtual reality videos and common videos for cardiac arrest recognition. Methods: A sequential mixed methods study was conducted, using qualitative interviews (with a total of seven experts) and a quantitative survey. Results: First, the cardiac arrest situation should be developed within 2-3 minutes after witnessing the patient collapse, for each of the four cardiac arrest videos about apnea, gasping, seizure, gasping, and seizure. Second, the education program should be designed so that the education on cardiac arrest recognition can proceed before CPR practice begins. Conclusion: 360° virtual reality videos and common videos for cardiac arrest recognition can play an important role in the education of the general public about cardiac arrest experience.
