Due to change in circumstances in the 2000s such as severe birthrate decline and shortened military service period, the armed forces of the Republic of Korea is currently turning to technologies and equipments from manpower, developing it to become high-tech, high-speed, and complex, resulting in an environment in which a single mistake could cause a mass mortality crisis.It is also evident that, considering aspects such as safety training curriculums and achievements of advanced countries and private education, hands-on training is a must in preventing suicides and accidents in the military, and establishing safety training centers is crucial for systematic and effective hands-on training.Soldiers who are joining the army as of now have experienced the Internet ever since they were born and easily use both virtual and augmented reality, and the current level of science and technology has developed to the point where most of the public safety experience centers are able to be replaced by virtual and augmented reality (VR/AR). Therefore, considering the aspects such as installation space, construction costs, maintenance costs, user characteristics, and education effects, other than for those trainings where real models and objects are more effective such as first aid training, it is with a strong recommendation that establishing military safety training facilities with VR/AR (Virtual and augmented reality) is a must in the coming future. We have derived the need for hands-on training by considering the development of virtual and augmented reality (VR/AR), analysis of operation status of the public safety experience centers, characteristics of military units, installation and maintenance costs, and proposed plan to establish safety training centers where effective training performance can be achieved at a lower cost than the public safety experience center. In addition, we suggested the scale of the required safety training center and the composition of the experience rooms considering the number of trainees and the environment of each military units. Given this analysis it will contribute to the prevention of military safety and suicide by building a safety training center in the future.

Virtual reality(VR) is known as immersive multimedia or computer-simulated reality, is a computer technology that replicates an environment, real or imagined, and simulates a user's physical presence and environment to allow for user interaction. Virtual realities artificially create sensory experience including sight, touch, hearing, and smell. Owing to the use of a single device in most VR contents, user have difficulty in manipulating user interface and game object. And also immersion of the game goes down because they can't see the mouse and keyboard in virtual space. In this paper, we design and implement the chess game to easily and accurately control user interface to improve the immersion in game.

With the rapid development of digital technology and the growing trend to integrate it into the medical field, recent studies suggest language rehabilitation for people with aphasia using virtual reality (VR), augmented reality (AR) and mobile applications. This study conducted a scoping review to summarize the features of digital technology-based language rehabilitation for aphasia in the last four years (2018-2021) and draw implications for future research. A total of 20 papers met the selection criteria among the documents retrieved from the Web of Science, CINAHL, and RISS. This review demonstrates that digital technology could offer unique treatment content by gamification, individualization, and creating a realistic communication environment, and by utilizing them in various ways. Therefore, we expect digital technology-based language rehabilitation for aphasia could supplement the limitations of conventional language rehabilitation and provide a novel perspective on development of treatment content.

가상현실 기반 훈련시스템은 3D 모델링 기법으로 개발되어 실시간 렌더링(Realtime Rendering)되는 훈련용 콘텐츠와 운동감 제공을 위한 모션플랫폼, 촉감 제공을 위한 햅틱장치 등 다양한 하드웨어를 이용하여 인간 감각에 대한 모의 체험환경을 제공함으로써 높은 훈련 몰입감을 제공한다. 훈련시스템의 구성요소 중 하드웨어들은 설계 성능을 바탕으로 정량적 시험평가로서 검증(Verification)과 확인(Validation)이 가능하나, 훈련환경에 대한 사실적 가시화가 요구되는 훈련용 콘텐츠는 시현을 위한 실시간 렌더링 성능 등의 정량적 시험평가 만으로 검증과 확인에 어려움이 많다. 본 연구에서는 일반 소프트웨어와 콘텐츠 소프트웨어 테스팅 요소 차이와 상용게임 콘텐츠와 훈련용 콘텐츠의 차이점을 분석하고, 훈련용 콘텐츠의 정량적 시험평가를 위한 명세서의 작성과 활용을 제안한다.

Recent studies have reported about UAV-based disaster rescue system adopting AR technology. Performing a disaster rescue training in an environment similar to an actual disaster site results in high costs and risk of accidents. In this paper, we propose a simulation software using VR technology so that rescuer can safely and inexpensively train the operation of the disaster rescue system. Through the analysis of the existing system, we derived the requirements for virtualizing training, and developed the simulation software using Unreal Engine and Airsim API. Simulation results show that the proposed simulation software can effectively simulate the operation of the conventional disaster rescue system.

Metaverse is the most emerging technology due to the recent 4th industry and the non-face-to-face society of Corona 19. As one of the core technologies of Metaverse, VR·AR technology is being industrialized in various fields such as medical care, education, and service. Among them, education and training are the most important fields of application, and nuclear power plant operation also requires this technology. In this paper, we will look at the fields of application of VR·AR technology in existing industries and suggest a plan for use in nuclear power plant work.

본 논문에서는 증대하고 있는 재난안전사고에 효율적으로 대응할 수 있도록 훈련할 수 있는 시뮬레이터 플랫폼을 제안한다. 최근 재난은 복합적이며, 타 부처 간의 협력이 필요한 대규모 성격을 띠고 발생하는 빈도가 커지고 있는 반면 훈련도구는 각 부처별로 재난유형별 시스템들이 필요에 따라 독립개발 및 운영되고 있기 때문에 다양한 시나리오에 의한 종합적 분석결과를 기반으로 하는 스마트한 재난대응 방안 모색이 어려운 실정이다. 이러한 이유로 본 연구에서는 재난에 대응하는 사람의 다양한 능력을 반영하여 인공지능 기반 하에 훈련 시나리오가 생성될 수 있는 지능형 재난대응훈련 시뮬레이터 개발을 위한 플랫폼을 제안한다. 또한 몰입감을 가지고 가상의 상황 하에서 훈련할 수 있도록 가상현실 기반의 시뮬레이터 플랫폼이 될 수 있도록 제안한다.
