최근 기업은 설계를 비롯한 모든 공정을 합리적이고 최적화된 기술을 도입하여 성장시키고 있다. 특히 ICT기반의 클라우드 플랫폼이 등장하여 기업 및 학교에서는 필요한 모든 비즈니스 서비스가 탑재된 솔루션의 등장으로 지금까지 경험하지 못한 기술교육 및 기업 성장에 영향을 주고 있다. 이 플랫폼을 활용한 HMD 디바이스의 가상현실 기술과 융합은 기업발전의 새로운 전환점이 되고 있다. 이에 본 연구의 방법으로 1차적으로 3DEXP와 HMD VR 기기 기반으로 디자인에 활용되는 VR 기능을 실험하였고, 2차적으로 앞에서 실험 데이터를 근거로 설문조사를 통해 디자인 활용성 연구 및 이 논점에 관한 연구하였다. 연구 결과 디자인 활용 측면에서 3DEXP와 HMD VR 기술은 밀접한 연관성을 가지고 있으며, 매개 회귀분석과 매개 요인의 HMD VR의 통계분석을 통하여 디자인 활용에 유의미한 것으로 증명되었다. 아직 일부 공대학생들을 연구대상의 결과로 일반화하기에는 부족하다. 하지만 HMD VR 기술 도입은 교육과 가상현실기술 구현의 한 축이며, VR 기술 활용 측면에서 일부 밝혀냈다는 점에서 의미가 있다.

The purpose of this study is to develop a method of applying AR(Augmented Reality)/VR(Virtual Reality) to educational and training systems from a comprehensive perspective, rather than applying AR/VR technology to specific education and training systems. We suggested whether to apply AR or VR technology to education and training system, the level of application of technology when constructing using AR/VR technology, and the criteria of priority among many education and training systems. To do this, we presented the framework of application of AR/VR technology, the evaluation criteria for selecting priority of education and training system applying AR/VR, and the systematic procedure for utilization of developed method. This study is significant in that it has developed a method to determine the direction of systematic AR/VR technology application for all education and training systems operated by the military or organization. This is expected to contribute to the overall efficiency of the organization in terms of economical utilization of the limited budget as well as the various benefits of utilizing basic AR/VR technology.

딥러닝에 기반한 광학 음악 인식 기술(Optical Music Recognition, OMR)을 사용하여 도출된 결과를 가상현실 (Virtual Reality, VR) 게임에 적용시킨 것을 제안한다. 딥러닝 모델은 YOLO v5를 사용했으며 검출되지 않은 객체를 검출하기 위해 Hough transform 사용, 보표 크기 수정 등을 수행한다. 출력된 결과 파일을 사용하여 VR 게임에서 BPM, 최대 콤보 수, 음정과 박자를 분석하여 사용하고 리소스 관리를 위한 Object Pooling 기술을 통해 노트가 밀리는 현상을 방지한다. 광학 음악 인식 기술을 통해 나온 음악 요소로 VR 게임을 제작하여 VR 콘텐츠 제공과 함께 광학 음악 인식의 활용성을 넓히는 것을 확인하였다.

In this paper, we present that Virtual Reality (VR) is a type of media that has attracted interest in storytelling and media utilization. VR was first discussed as a specific narrative medium with traditional story medium. Via this discussion, The innate difference of VR is that the role of the media users in which the narrative is communicated were active in the development of the narrative unlike that of most classical narrative media. We also discussed specific features related to VR based on the theories of traditional literary criticism, movie reviews, and plays. Through these discussions, we aruged two directions of VR storytelling production as an narrative medium, its specificity, and its expressiveness for VR producers. First, story processing and characters can be introduced as part of continuing a new narrative by altering the interaction history that appears in VR stories to user interest ratings. Second, VR interaction responds intuitively to the idea that it represents a trajectory across the story surface of all possible interactions. More specific theories and controvercials are discussed.

Background: This study was aimed at surveying the health science students' interest, demand, and awareness of virtual reality (VR) devices for learning to accumulate data necessary to develop and implement a curriculum with VR devices. Methods: We investigated the perception of health science students regarding VR device application and utilization. Statistical analyses were performed using SPSS 25.0 (IBM SPSS Statistics). Frequency and descriptive analyses were performed for the perception level of VR device use for university education. An independent twosamples t-test was performed to statistically analyze the perception level according to the VR device experience. A p-value < 0.05 was set to indicate statistical significance. Results: To the question "Do you wish to use VR devices for educational purposes?," 73% of the participants answered "yes." To the question "Do you think VR is necessary for the course curriculum?," over 65% answered "yes." Conclusion: In this study, health science students reported a great need for VR devices for education. VR-based classroom curriculum is expected to improve students' concentration, interest, and motivation.

This study investigates the characteristics of VR stores that emerged as new fashion communication media. Two case studies on Hyundai and eBay VR Department stores were conducted along with a discussion of the function and meaning of the fashion VR store. The results showed that both stores provide novel shopping experiences; however, the two were differentiated in terms of production method and technology implementation level. Functional aspects such as providing shopping efficiency and purchasing service was insufficient in both stores. Instead, they were complementing by means of product rotation, recommendation system, voice guidance, or linkage with an online shopping mall. In experiential aspects, both stores provided a strong sense of immersion. Hyundai VR store enhanced immersion with a high resolution image of a real offline store; however, it lacked in the ability to provide multisensory stimulation such as kinetic sense or auditory stimulation. The eBay VR Department store intensified the immersion experience by providing auditory stimulation as well as visual stimulation that enhanced the speed and distance sense through the utilization of animation. However, the extent of experience was limited in terms of agency and transformation because of the low interactivity found in both store systems.

The purpose of this study is to develop and technically implement the design and scenario of cabin safety contents for virtual reality (VR)-based cabin safety learning for aviation service majors. The process for developing VR cabin safety learning contents consisted of a total of four stages: learning stage, research stage, verification stage, and application stage. The cabin safety scenario items for the production of VR learning contents reflected the occurrence of an emergency, the procedure for survival from impact, and the evacuation procedure from the aircraft as the core. For the technical implementation of learning contents, modeling work is conducted by checking scenario reviews, types and numbers of objects related to equipment and facilities, and items of interaction. In addition, the connection work with the actual metaverse platform is carried out to enable the utilization of the manufactured facilities and equipment objects. Finally, application tests were carried out to reconfirm supplementary items.

Hands-on education and training is a key part of fixing and developing technology knowledge and is an inherent part of many engineering and scientific curricula. However, access to large complex training facilities, such as nuclear reactor, could be limited by various factors, such as unavailability of those facilities in the region, high traveling costs or harmonization of the schedules of hands-on E&T with theoretical lectures and with the operational schedule of the facility. To handle the issue, several success stories have been reached with the introduction of the Internet Reactor Labs (IRL). The Internet Reactor Labs can strongly contribute to accessibility of training at research reactors and can contribute to improvements in their utilization. The paper describes the development of the Internet Reactor Lab at the VR-1 reactor of the Czech Technical University in Prague. Contrary to single-purpose IRLs, it presents various modalities of online teaching and training in experimental reactor physics and reactor operation in general as well as outreach activities that have been developed in recent years.
