This study was performed to identify the difference in nursing process competency, critical thinking disposition and self-efficacy after applying virtual reality simulation education. The data were collected from 31 nursing college students using URL from February to April 2021 and analyzed SPSS 22.0. The pretest and posttest result of each group showed statistically significant improvements in nursing process competency(t=-3.776, p=.001), critical thinking disposition(t=-3.608, p=.001) and self-efficacy(t=-3.580, p=.001). As a result of this study, it was found that virtual reality simulation education improve nursing process competency, critical thinking disposition and self-efficacy of nursing students. Therefore, virtual reality simulation education will be the basis for preparing effective clinical practice education strategies for nursing students. It is suggested to have follow-up studies on virtual reality simulation education and various scenarios should be developed.

본 논문에서는 가상현실에서 작업 과정별 컨트롤러 활용에 관하여 연구한다. 가상현실은 실제와 유사한 공간적, 시간적 체험을 하게 하여 교육, 산업, 훈련, 관광 등 다양한 분야에서 가상현실을 활용하고 있다. 하지만 실제 작업 과정과 비교했을 때 컨트롤러의 모양, 진동, 시각효과, 소리 등 여러 차이로 인하여 몰입감이 떨어지는 상황이다. 본 연구에서는 그중에서 컨트롤러를 활용하여 실제 작업과정과의 차이를 줄이는 방법에 관하여 연구한다. 실제 작업 과정과 차이를 줄인다면 사용자에게 최적의 경험을 주고 현실 작업과 가상현실 작업과의 차이를 줄여 교육, 훈련, 산업 분야에 도움을 줄 수 있을 것으로 기대된다.

To maximize educational effect with new educational methods in the 4th Industrial Revolution era, immersive education has become the core type of education and virtual reality (VR) is at the center of realistic content. VR education is increasing in school, but researches on VR production education are insufficient. Our study has proposed a school-level curriculum for students to create their own VR content. The output and the survey results were analyzed to find out the learner characteristics of elementary school students, middle school students, and pre-service teachers at each school level. As a result, there were some noticeable differences in concentration, content subject, and production time according to school level. Primary school students focused on their subjects, middle school students related to learning, and pre-service teachers put top priority on contents useful for primary education.

As the software education which utilizes the virtual reality in the education field becomes more interested in the teachers and the students, researches are being conducted for the education of virtual reality contents production. The purpose of this study is to analyze the curriculum, outcomes, and evaluation results of virtual reality contents production for educational students, elementary school students, and middle school students. As a result of analysis on each group, there was no difference in adaptability to specific tools, differences in ability of object production in production, and self-confidence and interest in production and utilization of virtual reality in learning attitude.

This study examined the reality of military counseling education applied by the Army and studied the effects of military counseling training using virtual reality. First, we explored the cases of virtual reality application related to counseling, reviewed the virtual reality technology that can be benchmarked in the Army military counseling education, and examined the applicable technology. We classified the education method and the curriculum for the students and tested the difference using the analysis of variance, which is a statistical analysis method, through the satisfaction measurement of the current education. In addition, after having students experience virtual reality contents, the effects of practical training applied with virtual reality technology were derived and the difference in actual training was compared and analyzed through T-test. Then, the reliability of the study was improved by analyzing the effects of practical training using virtual reality by using the Analytic Hierarchy Process for the expert group who can consider the overall situation. Based on the results of the analysis, the development plan of military counseling training combined with virtual reality technology and the supplements of current military counseling education were presented as policy implications.

본 논문에서는 가상현실을 기반으로 하는 컴퓨터 조립과정 학습 시스템을 구현하였다. 컴퓨터 조립과정을 교육하는데 있어서는 실습이 가장 중요하다. 그러나 기존의 자료들은 과정을 설명한 텍스트나, 2차원 이미지 데이터를 사용하고 있어 그저 보여주는 학습에 그치고 있다. 이런 단점을 보완하기에는 가상현실을 이용한 학습이 가장 좋은 대안일 것이다. 본 논문은 VRML과 EAO를 이용한 Java를 사용하여 시스템을 구현하였다. 이는 학습자들에게 좀더 현실감 있는 교육환경을 제시해 주어서 학습효과를 극대화시킬 수 있다.

The purpose of the study was to review the evidence of effects of virtual reality (VR) technology in nursing education. Four databases were searched for articles publised until November 2018 that databases include PubMed, Proquest (nursing and allied health), CINAHL, & RISS. Key word used for search include 'education, nursing', 'simulation', 'skill training', 'virtual reality' and 'VR'. Of 695 papers searched, Seven studies were selected for data analysis. Of seven studies, five studies used quasi-experimental design and two used one group design. There were two studies used VR technology for skill training and five were scenario based VR simulation program. Studies evaluated outcomes including students performance, time spent on practice, self-efficacy and communication ability that most studies reported positive effects while some figures were not statistically significant. The findings of this study provides evidence of nursing education program using VR, however, additional research with rigorously designed studies using systematized measurements for study outcomes are required. In addition, comparison with existing skill training and simulation education should be considered in the future studies.

가상현실 (Virtual Reality, VR) 기술은 3차원 가상공간 내에서의 높은 몰입감에 기반한 체험을 바탕으로 다양한 분야에서 활용되고 있다. 소방훈련이나 태풍, 지진 등 재해 대응훈련과 같이 인명피해의 위험이 있는 재해에 대한 VR 기술을 활용한 방재교육은 위험성을 동반하지 않으면서도 현장감에 기반한 높은 교육적 효과를 창출할 수 있다. 한국전자통신연구원에서는 VR 기술을 이용하여 소방훈련을 위한 실감 소방훈련 시뮬레이터를 개발한 바 있으며 목동재난체험관에서는 홍수, 태풍, 지진 등 다양한 재해에 대한 안전교육을 위한 자연재해 가상현실체험을 운영하고 있다. 이외에도 전국 지자체 및 교육청에서는 방재교육을 목적으로 VR 기술을 활용하고 있다. 그러나 기존의 VR을 활용한 수재해 방재교육은 범람의 수리학적 특성과 함께 수해지의 지형적 특성을 적절히 반영하지 못하는 단점을 가지고 있다. 이는 방재교육이나 경각심을 부각하는 데엔 효과적이나 실질적인 방재 가이드라인을 제시하는 데엔 한계가 있다. 본 연구는 몰입형 파랑해석모형인 Celeris Base를 기반으로 3차원 가상현실 시각화를 활용한 수리학적 홍수추적 모형을 개발하였다. 3차원 가상현실 시각화는 Unity3D를 이용하여 모의환경 내에 구현되었다. 강우-유출 과정의 수리학적 해석을 위해 동수역학 수치모형의 연속방정식 내에 강우와 침투에 대한 항을 추가하였다. 침투모형으로는 Horton 모형, Green-Ampt 모형과 함께 사면의 기울기를 고려한 Green-Ampt 모형을 적용하였다. 실제 유역에서의 홍수추적 모의결과는 관측값과 비교적 잘 일치함을 확인하였다. 개발된 모형은 VR 방재교육을 통해 일반인의 수재해 대응능력 향상에 기여함과 동시에 정확성 높은 홍수추적 모의결과에 기반한 홍수대책 마련에도 활용 가능할 것으로 기대된다.
