Background: This study was aimed at surveying the health science students' interest, demand, and awareness of virtual reality (VR) devices for learning to accumulate data necessary to develop and implement a curriculum with VR devices. Methods: We investigated the perception of health science students regarding VR device application and utilization. Statistical analyses were performed using SPSS 25.0 (IBM SPSS Statistics). Frequency and descriptive analyses were performed for the perception level of VR device use for university education. An independent twosamples t-test was performed to statistically analyze the perception level according to the VR device experience. A p-value < 0.05 was set to indicate statistical significance. Results: To the question "Do you wish to use VR devices for educational purposes?," 73% of the participants answered "yes." To the question "Do you think VR is necessary for the course curriculum?," over 65% answered "yes." Conclusion: In this study, health science students reported a great need for VR devices for education. VR-based classroom curriculum is expected to improve students' concentration, interest, and motivation.

최근 기업은 설계를 비롯한 모든 공정을 합리적이고 최적화된 기술을 도입하여 성장시키고 있다. 특히 ICT기반의 클라우드 플랫폼이 등장하여 기업 및 학교에서는 필요한 모든 비즈니스 서비스가 탑재된 솔루션의 등장으로 지금까지 경험하지 못한 기술교육 및 기업 성장에 영향을 주고 있다. 이 플랫폼을 활용한 HMD 디바이스의 가상현실 기술과 융합은 기업발전의 새로운 전환점이 되고 있다. 이에 본 연구의 방법으로 1차적으로 3DEXP와 HMD VR 기기 기반으로 디자인에 활용되는 VR 기능을 실험하였고, 2차적으로 앞에서 실험 데이터를 근거로 설문조사를 통해 디자인 활용성 연구 및 이 논점에 관한 연구하였다. 연구 결과 디자인 활용 측면에서 3DEXP와 HMD VR 기술은 밀접한 연관성을 가지고 있으며, 매개 회귀분석과 매개 요인의 HMD VR의 통계분석을 통하여 디자인 활용에 유의미한 것으로 증명되었다. 아직 일부 공대학생들을 연구대상의 결과로 일반화하기에는 부족하다. 하지만 HMD VR 기술 도입은 교육과 가상현실기술 구현의 한 축이며, VR 기술 활용 측면에서 일부 밝혀냈다는 점에서 의미가 있다.

Virtual reality (VR) simulation in nursing education, especially in the teaching of VR simulations just prior to clinical practice, has the potential to enhance the effectiveness of clinical practice and better prepare nursing students for patient care. The aim of this study was to evaluate the effect of a preclinical VR simulation education program on the development of critical thinking, self-efficacy, problem-solving ability, and perceived clinical competency among undergraduate nursing students. The study was conducted between May and June 2021 using a pretest-posttest design with a control group. A total of 42 nursing students were recruited through convenience sampling from two separate classes. The intervention group participated in VR simulation education, while the control group engaged in lecture-based education, before beginning clinical practice. Assessments were conducted before preclinical education and after completing clinical practice using structured questionnaires. The data was analyzed using chi-square tests, independent t-tests, and ANCOVA. The findings indicated that the intervention group had a significantly higher score in perceived clinical competency compared to the control group (F = 5.25, p = 0.029) after controlling for pretest scores. However, there were no statistically significant differences in critical thinking, self-efficacy, or problem-solving abilities between the two groups. These findings suggest that preclinical VR simulation education is partially effective in preparing nursing students for their clinical practice, underscoring the need for a balanced educational approach that integrates VR with clinical practice to develop a full spectrum of nursing skills and knowledge.

국가기관과 기업은 정비사를 양성을 위한 고등학교부터 대학교, 기업 훈련센터 같은 교육기관을 만들어 숙련된 정비사로 훈련시키려고 많은 노력을 하고 있다. 하지만 교재를 이용한 이론교육과 현장에서 사용하지 않는 장비를 이용한 실습교육으로는 제대로 된 정비교육을 진행하지 못하며 특수장비를 활용한 교육이나 위험한 상황을 가정한 정비의 교육은 매우 위험하여 영상이나 사진으로 교육을 진행하고 있었다. 최근에는 VR과 AR을 접목하여 단순정비에서 특수정비까지 시뮬레이션으로 안전하게 상황을 체험하고 문제를 해결하는 효과적인 교육 시뮬레이션이 연구되고 개발되는 사례가 많이 있다. 본 논문에서는 다누리 VR과 DisTi Engine, Remote AR을 비교분석하고, 유니티 엔진 기반으로 외부에서 전달된 정보를 기반으로 콘텐츠를 디바이스 화면에 최적화하여 출력하는 AR API를 소개하고, VR 디바이스인 HTC Vive의 컨트롤러와 HMD의 정보를 실시간으로 수집하고 수집된 정보를 파일에 저장하는 VR API를 구현한 사례를 소개했다. 본 연구에서 구현한 API를 사용하면 콘텐츠를 제작할 때 도움을 줄 수 있을 것이다.

In the era of noble technology, virtual reality (VR) has been adopted in various fields, with the advantages of VR in education being confirmed through numerous studies. In skill development training education, humans or equipment that interact with the trainee are crucial and currently VR is more preferred. In this study, six projects were selected and reviewed in-depth visualizing the use of VR in training and its potential. Comparison between the learning actions of training in the virtual and real environments were conducted. Training through VR is location-dependent, time-dependent, safe, and reversible. VR application is also determined by the preps and feedback-providing functionality which must be emphasized. All the advantages of VR in skill development training make it an opportunity provider. This article can be used by those developing VR projects for skill development training.

Three-dimensional (3D) modeling of the liver can be especially useful for both the surgeon and patient to understand the actual location of the tumor and planning the resection plane. Virtual reality (VR) can enhance the understanding of 3D structures and create an environment where the user can focus on contents provided. In the present study, a VR platform was developed using Unreal Engine 4 software (Epic Games, Potomac, MD, USA). Patient's liver based on magnetic resonance image was imported as a 3D model that could distinguish liver parenchyma, vascular structure, and cancer. Preoperative education videos for patients were developed. They could be viewed inside the VR platform. To evaluate the usefulness of VR education program for patients undergoing liver resection for hepatocellular carcinoma, a randomized clinical trial evaluating the knowledge and anxiety of the patient was designed. The case presented in this report was the first experience of performing the VR education program and examining the knowledge and anxiety using questionnaires. When the knowledge score increased, the anxiety score also increased after the education program. Based on findings of this pilot case study, the timing and place where the questionnaire will be answered can be modified for formal initiation of the randomized controlled study to examine the usefulness of VR in patient education.

The purpose of this study is to develop a method of applying AR(Augmented Reality)/VR(Virtual Reality) to educational and training systems from a comprehensive perspective, rather than applying AR/VR technology to specific education and training systems. We suggested whether to apply AR or VR technology to education and training system, the level of application of technology when constructing using AR/VR technology, and the criteria of priority among many education and training systems. To do this, we presented the framework of application of AR/VR technology, the evaluation criteria for selecting priority of education and training system applying AR/VR, and the systematic procedure for utilization of developed method. This study is significant in that it has developed a method to determine the direction of systematic AR/VR technology application for all education and training systems operated by the military or organization. This is expected to contribute to the overall efficiency of the organization in terms of economical utilization of the limited budget as well as the various benefits of utilizing basic AR/VR technology.

Purpose To develop an educational program using virtual reality (VR) and augmented reality (AR) in oriental medicine education, this study investigated the status of programs currently being used mainly in the fields of medicine, nursing, and dentistry, and was the basis for developing an oriental medicine education program. We plan to use this for future research purposes. Methods To investigate medical simulation education using VR and AR technologies, 72 studies were searched using the ProQuest Central Database (period 1.1.2000 to 10.10.2023.) Of these, 22 were selected for analysis. Results Among the selected studies, the educational fields of the program were 59% (13 studies) in medicine, 32% (7 studies) in nursing, 9% (2 studies) in dentistry, 73% (16 studies) were VR in terms of applied technology, and 27% (6 studies) in AR. Conclusions Recently, research on VRand AR has increased in the medical field. As patient rights and medical environments change, clinical practice education programs using new technologies are needed, in addition to traditional face-to-face practice. Related research is expected to be active in the field of Oriental medicine in the future.
