We proposed a new system for the postural balance rehabilitation training. For the purpose, we used the virtual hiking system using virtual reality technology. We evaluated the system by measuring the parameters such as path deviation, path deviation velocity, cycling time, and head movement. From our results, we verified the usefulness of virtual reality technology in rehabilitation. Our results showed that this system was effective postural balance rehabilitation training device and might be useful as the clinical equipment.

The purpose of this study is to design a system that can be used for military simulation and virtual training using the location information of individual soldier's weapons. After acquiring the location information using Arduino's GPS shield, it is designed to transmit data to the Smartphone using Bluetooth Shield, and transmit the data to the server using 3G/4G of Smartphone in real time. The server builds the system to measure, analyze and manage the current position and the tracking information of soldier. Using this proposed system makes it easier to analyze the training situation for individual soldiers and expect better training results.

In order to study the correlation between the pilot's cognitive ability and recovery ability by applying a physical element that can cause spatial loss of position to the pilot, a turntable was installed on the top of the motion system to give a quantitative rotational error. We propose a method of simulating flight movement to reduce a difference in feeling and an intuitive method of forward kinematic analysis.

In the era of 'Untact', virtual reality-based job training platforms are actively being used as part of non-face-to-face education for students with developmental disabilities. Because the people with developmental disabilities may lack sufficient cognitive abilities, it is difficult to conduct untact training seamlessly without the help of a third party. Therefore, it is necessary for training programs to identify the right timing to provide help so that the training can be continued. This research analyzed the visual attention of students with developmental disabilities in virtual reality-based job training program in order to determine the point of time when an intervention is required by the trainee. Results showed that students who completed the mission tended to have intense visual attention on a small number of objects for a certain period of time; the visual attention of the students who failed tended to shift erratically among multiple objects.

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.

육군은 90년대부터 워게임 모의모델을 활용하여 군단 전투지휘훈련, 전구 연합지휘소연습, 사·군단 작전계획 검증을 하였으며, 현재는 차세대 워게임 모의모델을 개발하기 위한 기술적 검토단계에 있다. 워게임 모의모델의 객체인 가상군을 자동화하기 위한 연구는 오래전부터 진행되었으나, 규칙기반 시스템을 적용한 반자동화군에 대한 연구가 일부 진행된 수준이다. 이에 본 논문에서는 게이머 행동패턴을 기반으로 학습한 인공지능으로 차세대 육군 워게임모델의 대항군 기동부대를 완전자동화하는 방안을 제안하였다.

본 논문에서는 제한된 공간에서 효과적인 기초연습이 필요한 장애인 핸드볼 선수들을 대상으로, XR(Extended Reality) 기술을 활용한 특화된 훈련 서비스를 개발하고자 한다. 경기장에 물리적으로 참석할 필요 없이 집이나 사무실에서 편안하게 핸드볼 게임을 경험하고 연습할 기회가 현재 제한되어 있다. 이 연구의 목적은 장애인이 멀티플레이어 환경에서 기초 연습하는 방법 개발에 중점을 두어 이러한 한계를 해결하는 것이다. 이를 통해 선수들은 제한된 실내 환경에서도 가상 현실(VR) 및 증강 현실(AR)을 활용하여 핸드볼 게임을 쉽게 경험하고 연습할 수 있는 가능성을 제공한다.

Commander and staffs on the battlefield are aware of the situation and, based on the results, they perform military activities through their military decisions. Recently, with the development of information technology, the demand for artificial intelligence to support military decisions has increased. It is essential to identify, collect, and pre-process the data set for reinforcement learning to utilize artificial intelligence. However, data on enemies lacking in terms of accuracy, timeliness, and abundance is not suitable for use as AI learning data, so a training model is needed to collect AI learning data. In this paper, a methodology for learning artificial intelligence was presented using the constructive wargame model exercise data. First, the role and scope of artificial intelligence to support the commander and staff in the military decision-making process were specified, and to train artificial intelligence according to the role, learning data was identified in the Chang-Jo 21 model exercise data and the learning results were simulated. The simulation data set was created as imaginary sample data, and the doctrine of ROK Army, which is restricted to disclosure, was utilized with US Army's doctrine that can be collected on the Internet.
