The research of combining virtual reality technology with the design elements of children's picture book education is a relatively new topic in virtual reality technology in recent years. Based on the combination of picture book design elements with virtual reality technology and the development of a children's picture book teaching game, this article analyzes the effectiveness of the application of virtual reality technology in children's teaching, and explores the usability of picture book design elements in teaching [1]. Through literature research methods, practical research methods and investigation research methods, this paper lucubrates the application of virtual reality technology in the design elements of children's picture book education so as to provide adequate theoretical and practical support for the research theme. The spatial positioning, vision, sound, and functional requirements of children's picture book games play a leading role in teaching. Practical statistics have proved that it is easier to promote children's mastery of teaching knowledge in a virtual environment. Moreover, use VR's game management function and setting function to solve the boringness of traditional education methods and the limitations of the teaching environment. The feasibility of game operation provides a virtual teaching platform system for children's education, and the teaching effect is remarkable.

With the advent of the Fourth Industrial Revolution, virtual reality, a technology that has recently attracted attention, is emerging as a core technology that will lead the future industry by changing the paradigm of various industries. The development of 3D rendering, computer graphics, and mobile technologies enabled the development of various smart devices and led to the popularization of virtual reality services using them. Recently, with the development of virtual reality-related technology, various devices and contents such as VR-related HMDs are being developed and released. However, since the classification for VR technology has not yet been established, it is difficult to define a range of industries and services to which VR can be applied. Therefore, in this study proposes a service classification system in terms of industries that can apply VR technology and services that can be provided based on the studies on industries and services of VR technology related to the Fourth Industrial Revolution. VR's industrial classification consists of eight industries including entertainment, media, education, medical care, architecture, manufacturing, distribution, tourism and each service is divided into two service categories and composed 16 services. Through the collection and analysis of virtual reality service cases, the service distribution and characteristics of each industry can be analyzed. In addition, we can develop a virtual reality new business model and present a service case for the intersecting areas. This study is expected to be used as a basic research for the activation of virtual reality services in the future.

Recently, virtual reality (VR) and augmented reality (AR) have received increasing attention, with the development of VR/AR devices such as head-mounted displays, haptic devices, and AR glasses. Medicine is considered to be one of the most effective applications of VR/AR. In this article, we describe a systematic literature review conducted to investigate the state-of-the-art VR/AR technology relevant to plastic surgery. The 35 studies that were ultimately selected were categorized into 3 representative topics: VR/AR-based preoperative planning, navigation, and training. In addition, future trends of VR/AR technology associated with plastic surgery and related fields are discussed.

본 연구는 군(軍)에서 적용하고 있는 병영상담교육의 현실태를 살펴보고 가상현실을 활용한 병영상담 실습교육의 효과를 연구하였다. 먼저 상담에 관련한 가상현실 적용사례를 탐색하고 육군 병영상담교육에 벤치마킹(Benchmarking)할 수 있는 가상현실 기술을 검토하여 적용이 가능한 기술에 대해 고찰하였으며 교육생을 대상으로 교육방법과 교육과정을 분류하여 현 교육의 만족도 측정을 통해 통계적 분석방법인 분산분석을 사용하여 차이를 검정하였다. 또한 가상현실 콘텐츠를 교육생에게 실제 경험하게 한 후 가상현실 기술이 적용된 실습교육효과를 도출하고 현재 실습교육과 차이를 T 검정으로 비교 분석하였다. 이어 전반적인 상황을 고려할 수 있는 전문가 집단을 대상으로 계층적 분석기법을 활용하여 가상현실을 활용한 실습교육의 효과에 대해 분석하여 연구의 신뢰성을 높였다. 분석결과를 바탕으로 가상현실 기술이 접목된 병영상담실습교육의 발전방안과 현(現) 병영상담교육의 보완사항을 정책적 시사점으로 제시하였다.

가상현실 산업의 성장으로 인해 이용자 수가 급격히 증가하면서 가상현실환경에서 보안이 중요시 되고 있다. 가상현실 서비스를 안전하게 사용하기 위해서는 사용자가 보안취약점과 보안 위협의 심각성을 인지하고 보안 대책을 갖추어야 한다. 하지만 취약점 및 보안 위협에 대한 정보부족뿐만 아니라 사용자들의 보안 의식 또한 미흡하다. 이러한 점을 돌이켜 생각해 볼 때 가상현실환경에서 보안 가이드라인이 필요하다. 본 논문에서는 가상현실 서비스를 보다 안전하게 제공하기 위해 고려해야 할 보안 요구사항을 제시한다.

The application of visual and auditory senses into virtual reality is easily taken for granted, but the sense of smell has been largely ignored. But many researches have shown that olfactory stimulation in virtual environments can increase the immersion and reality. In practical virtual reality, the use of scents is not always able to increase the immersion and reality. An ill-matched scent can decrease the reality. To solve this problem, we developed scent devices that can adjustable scents and scent intensity in order to display a well-matched scents in virtual reality. And we propose simple and practical way to program specific location to display scents and developed API function to control a developed scent device at virtual reality software.

5세대 이동통신 기술의 발전은 이상(理想)적 초연결 사회 정보통신기술(ICT)을 가시화하고 있다. 특히 가상현실(VR)기술은 새로운 확장과 도약의 출발점에 놓여있다. 본 연구는 이러한 맥락에서 가상현실을 미디어로 규정하고, 공간과 소통이론을 중심으로 그 확장성에 대한 담론들을 수집·분석(thematic literature review)하였다. 먼저 1990년 가상현실 개념의 초기 논의들을 시작으로 개념을 정교화하였으며, 물리적 세계와 디지털 정보의 관계, 매체로서 표현과 상호작용 몰입감, 시뮬레이션, 예술창작론, 그리고 마지막으로 진화적 발전방향에 대해 논의하였다. 결론적으로 가상현실의 기술에 대한 담론들을 넘어 학술적 대상으로 가상현실의 발전과 진화를 위해 인지과학, 신경과학, 사회과학, 그리고 인문학적 쟁점(윤리, 인격 등)에 대한 이론적 프레임워크가 요구됨을 필역하였다. 즉, 가(假)를 넘어 가(加)로 넘어갈 수 있는 가상현실 진화가 논의될 시점이다.

We are designed to solve cyber motion sickness, an important task that must be addressed for the growth of the virtual reality content industry. Not only the industry but also academia are paying a lot of attention. However, despite long interest and research on the phenomenon of cyber motion sickness, a solution has not been drawn. This is deeply related to the lack of tools that can effectively measure cyber motion sickness. Therefore, in this paper, prior studies on cyber motion sickness were analyzed to develop a tool that can effectively measure cyber motion sickness when users experience immersive virtual reality. The measurement method of cyber motion sickness used in previous studies, each characteristic and limitation, and common factors related to cyber motion sickness were analyzed. Each of the related factors was derived as sub-factors. Based on the analyzed contents, an effective cyber motion sickness measurement evaluation tool model in immersive virtual reality was presented. It is expected that the evaluation tool model can be used for the study of cyber motion sickness.
