최신 IT 기술 변화의 중심점에 있는 3D 가상현실이란, 어떤 특정한 환경이나 상황을 컴퓨터로 만들어서, 그것을 사용하는 사람이 마치 실제 주변 상황 환경과 상호작용을 하고 있는 것처럼 만들어 주는 인간-컴퓨터 사이의 인터페이스를 하는 컴퓨터 프로그래밍 기법이다. 이처럼 무한한 가능성을 가진 3D 가상현실을 이용한 여러 가지 프로젝트가 쏟아져 나오고 있다. 현재 의학에 관한 실습 지식을 배우는데 있어서 장비 및 상황이 여의치 않은 경우가 많다. 위와 같은 필요성을 기본으로 하여, 본 논문에서는 가상현실을 기반으로 만든 간단한 의학시술 과제를 통해 교육생들이 실습해보고 기본적인 실습 흐름 및 의학 지식을 습득할 수 있는 간호 교육 시뮬레이션을 개발하였다. 환자의 상태와 병명을 표기해주며 위 환자에게 투여할 수 있는 약에 대한 선택을 교육생에게 주어준다. 교육생은 환자에게 투여할 약을 선택하고 투약할 약의 양을 조절하며, 마지막으로 투약하는 방법에 대해서 선택지를 통해 선택한다. 가상현실을 통해 몰입감을 높일 수 있어 간호교육에 효율적이다.

The purpose of this study is to analyze elementary school students' interest in virtual reality(VR) technology, usability, and the possibility of learning media. In particular, it is intended to be used for content creation for artificial intelligence(AI) education in the future. The effectiveness of elementary education using virtual reality technology was confirmed through the analysis of overseas research, and the applicability to elementary school students in Korea was analyzed. To proceed with the analysis, various virtual reality contents were provided to 5th grader of elementary school, and then, interest, usability, usefulness, and possibility of use in class and learning were surveyed. As a result of the study, it was confirmed that students' interest in virtual reality contents was very high, and that it could be used sufficiently as a learning medium. It suggests that it can be used in artificial intelligence education and data science education, which have recently been emphasized in importance. In particular, virtual reality can be used to simulate abstract data and artificial intelligence.

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.

기후변화, 도시화 등 다양한 요인에 의하여 도시 침수 위험성은 더욱 커지고 있다. 높은 인구밀도와 더불어 학교, 병원 등 인프라가 집중된 도시지역의 경우 대규모 홍수가 발생할 경우 수많은 인적, 경제적 피해로 이어지게 된다. 도시지역 내 침수 위험성을 최소화하기 위해 정확하고 빠른 도시침수모형의 개발과 더불어 사전에 이를 최소화하기 위한 방재교육의 중요성이 더욱 강조되고 있다. 가상현실 (Virtual Reality, VR) 기술은 높은 몰입감을 통해 사용자의 자발적 참여를 유도하여 기존의 교육매체 대비 높은 교육적 효과를 보이고 있다. 특히 침수 등 인명피해 위험성을 내재한 재해에의 VR 적용은 위험성을 동반하지 않아 더욱 효과적이다. 종래의 VR 기반 침수 방재교육은 침수의 동수역학적 거동과 대상 지역의 지리적 특성을 적절히 고려하지 못하여 방재교육에는 효과적이나 방재시스템으로의 활용엔 한계가 있다. 본 연구는 몰입형 파랑해석모형인 Celeris Base를 토대로 몰입형 도시 침수 수치모형을 개발하였다. Unity3D로 개발된 Celeris Base는 가상현실 장비인 HMD (Head Mounted Display) 기술을 이용하여 실시간 모의결과를 360도 가상현실 공간 내에 가시화할 수 있다. 도시지역 내 강우에 의한 침수를 모의하기 위해 연속방정식 내에 강우, 침투 항을 고려하였다. 침투모형으로는 도시지역 내 침수모의에 일반적으로 사용되는 NRCS-CN 방법을 사용하였다. 본 연구는 개발모형을 이용하여 2022년 8월 발생한 집중호우에 의한 강남역 일대 침수 사상을 수치적으로 재현하고, 이를 가상현실 모의환경 내에 가시화하였다. 모의결과는 집중호우 발생 시 지형적 특성에 따라 강남역과 역삼역 인근에서 집중적으로 침수피해가 발생하였음을 확인하였다.

The Republic of Korea Army (ROK Army) is trying to improve the effectiveness of education and training. On the other hand, there are many restrictions in actual training, limiting their practical education and training. Virtual reality technology is being used to overcome these limitations. Virtual reality technology is developing in various types, and the ROK Army needs to introduce a virtual reality training system for cost-effective education. The ROK Army mainly uses high-cost simulator-types that are similar to real equipment. Recently, a low-cost immersive-type virtual reality training system wearing an HMD is also being used. This study analyzed the cost education effectiveness of simulator-type and immersive-type virtual reality training systems in operation at the ROK Army air defense school. First, the research method used AHP to analyze the educational effects. Second, the cost was applied to the production cost of the virtual reality training system to analyze the cost-effectiveness of the education. The immersion-type was 3.4 times higher than the simulator-type in terms of cost effectiveness. These results can be used as basic data for analyzing the cost-effectiveness of a virtual reality training system.
