With the development of digital technology and the influence of the global pandemic, the metaverse, a three-dimensional virtual world, is receiving attention in society, economy and overall industry, and the manufacturing industry is also accepting it as a major strategic agenda for digital transformation. Therefore, in this study, the concept of the industry metaverse from the perspective of the manufacturing industry was defined, and the types of the industry metaverse were classified into four types by reflecting the characteristics of the manufacturing industry based on the general metaverse scenario presented in previous studies. These are Virtual behavior simulation, Augmented operation of business objects and Virtual experience simulation, Augmented decision of business subjects. In addition, through case analysis of solutions used in the manufacturing industry, it was confirmed that the central technology of the Industry Metaverse is the digital twin, and that it is being implemented by convergence with major digital technologies such as virtual reality, augmented reality, digital human, and AI. This study will be able to provide guidelines for future research on the metaverse from the perspective of the manufacturing industry and establishment of a digital transformation strategy for the industry.

재난안전사고는 인명과 재산 손실에 막대한 피해를 주기 때문에 이에 대한 대비와 대응이 국가적으로 산업적으로 중요하게 다루어지고 있다. 최근 정부와 산업체에서도 그 중요성을 인식하고 재난의 원인과 대책 마련에 대한 연구와 해결 방법을 다각적으로 모색하고 있다. 가상현실 기술을 적극적으로 활용한다면 사회적 비용을 절감하면서 재난에 대한 대비와 훈련이 용이할 것이다. 하지만 이에 대한 학술적인 연구는 의외로 활발하지 못한 실정이다. 무엇보다도 재난안전을 가상현실 콘텐츠와 접목하여 총체적으로 분석하거나 정리한 자료는 찾기가 쉽지 않다. 따라서 본 논문에서는 재난안전의 유형별 현황을 사고유형과 물리적 피해 등을 토대로 정량적 자료를 분석하고 정리하였다. 또한 가상현실 콘텐츠에 적용되고 있는 국내외 현황을 분석하여 그 특징을 살펴보고 그 의미를 고찰하고 시사점에 대해 논의하였다. 이를 위해 재난안전 가상현실 콘텐츠 범주에서 국내외 개발 사례를 탐구하고 특징을 정리하였다. 또한 향후 재난안전 콘텐츠의 고도화와 그 효과를 높이기 위해 요구되는 가상현실 기술과 재난안전 콘텐츠에서 고려되어야 할 이슈를 제안하였다.

Safety is paramount for construction industry throughout the world. Human errors which contribute to more than half of construction accidents, could be proactively prevented through effective education and training methods. Although Virtual Reality (VR) and Augmented Reality (AR) have gained much attention in various disciplines, few studies applied them for construction safety education. This research presents a new approach in construction safety education by utilizing VR and AR. The vision of aligning teaching & learning strategies is examined in order to ensure the potential benefits of the new method. This innovative approach shifts safety education from "Listen, and I will forget. See, and I may remember" towards "Practice, and I understand".

Recently, virtual reality (VR) and augmented reality (AR) technologies are attracting attention as core technologies in the era of the 4th industrial revolution. These virtual and augmented reality technologies are being used in a variety of industries, including the construction industry, healthcare industry, and manufacturing industry, to innovate in communication and collaboration, education and simulation, customer service and reinvention of the customer experience. In this paper, VR-based experiential safety education was conducted for workers of shipbuilding companies in Ulsan city, and for them, the educational effectiveness such as immersion, site applicability, safety accident prevention, education satisfaction, overall performance, and safety behavior in VR-based safety experience education were measured. In addition, we examined whether the immersion of VR-based safety experience education affects site applicability, safety accident prevention, educational satisfaction, overall performance, and safety behavior. Furthermore, it was analyzed whether site applicability plays a mediating role in the relationship between immersion and safety accident prevention. As a result, it was found that the immersion of VR-based safety experience education affects site applicability, safety accident prevention effect, education satisfaction, overall performance, and safety behavior, and that site applicability mediates between immersion and safety accident prevention. Based on these results, we suggests a direction for the development of VR-based contents in the field of safety and health and the transformation of safety and health education in the future.

Virtual reality technology is very useful for the 21C science education, and is able to contribute to the development of new teaching and learning methods in science education. One of these computer-based technologies, virtual reality, is possible to use in many directions. It is a new communication medium that is receiving a lot of attention, and is usually identified by a collection of technological hardware. Virtual reality is defined as a highly interactive, computer-based, multimedia environment in which the user becomes the participant, with the computer in a virtual real world. A key feature of virtual reality is real-time interactivity, in that the computer is able to detect user inputs and instantaneously modify the virtual world. It is being used in a wide variety of fields including physics, chemistry, human biology, biomedical sciences, military, architecture, industry and the entertainment. In classroom, using science educational program developed by virtual reality technology can increase the interests of students, promote understanding of basic science concepts, help laboratory skills, and encourage creative learning for them.

Virtual Reality makes a virtual environment more realistic and, furthermore, it provides a variety of experiences which we cannot have in reality. A drastic growth of GPU performance and increase of computing capability make virtual environment more realistic than ever. One important element of constructing virtual environment is to animate 3D characters. Many researchers have been studying 3D characters animating and a myriad of methods have been proposed to make them more realistic. In this paper, we discuss the technologies and characteristics of 3D character animation. We believe that realistic characters in Virtual Reality will be applied to various fields: education, film and game industry, business and, particularly, medical area such as telemedicine, virtual surgery, etc.

Extended reality (XR) provides an immersive virtual experience by using various media. The XR virtual environment enables interactions between the real and virtual worlds in virtual, augmented, and mixed reality scenarios. XR is being used in various areas such as industry, medical care, road transportation, gaming, education, and culture. XR and multimedia enhancement are important business scenarios for fifth-generation (5G) mobile networks. As users' demand for emerging media services gradually increases, enhancements in networks should be implemented for delivering multimedia services such as XR. We describe related standardization trends and requirements of the XR service in 5G mobile networks. We also discuss technological enhancements for 5G mobile networks as specified by the 3GPP SA2 working group.
