The VR(Virtuality Reality) technology provides very close experience to reality by stimulating humans' external recognition with artificial technologies. In order to overcome the limitation of real-environment training, VR is being applied in industry field as a key technology to prevent safety accident and its control procedure training. However, it is difficult to build VR-based training system because 3D modeling and software coding are necessary for materialization of VR environment demands of many development resource. In this research referring to VR based training content implementation, a method to utilizing VRDC(VR-based Dynamic visualization Component) is suggested and by applying it to plant safety training system, it was confirmed its practicality.

In the era of noble technology, virtual reality (VR) has been adopted in various fields, with the advantages of VR in education being confirmed through numerous studies. In skill development training education, humans or equipment that interact with the trainee are crucial and currently VR is more preferred. In this study, six projects were selected and reviewed in-depth visualizing the use of VR in training and its potential. Comparison between the learning actions of training in the virtual and real environments were conducted. Training through VR is location-dependent, time-dependent, safe, and reversible. VR application is also determined by the preps and feedback-providing functionality which must be emphasized. All the advantages of VR in skill development training make it an opportunity provider. This article can be used by those developing VR projects for skill development training.

Safety education for crew members is an essential education because it is directly related to life. When ship emergency response training is provided as a hands-on training rather than a sit-down training, the satisfaction of trainees and the educational effect are higher. However, for ship emergency response training to be conducted through practical training, educational conditions such as time and place are insufficient in reality. In recent years, the use of VR technology in education has been in the spotlight. Practicing through virtual reality is an educational method that other educational institutions are also aiming for because it can increase the educational effect regardless of time and place. On the other hand, in order to provide VR-based education, it is essential to develop related technologies and develop contents. In this study, VR-based content development was performed. The development scenario is about navigation and accident response plan, and it was developed for navigation in narrow waterways and limited visibility.

This study investigates the user experience (UX) of first aid training using virtual reality (VR) technology. As VR continues to be adopted for educational and training purposes, it is important to understand how learners perceive and engage with this medium for developing critical skills, such as first aid. In this study, we developed a VR application called "VR First Aid" that includes training modules on three emergency scenarios: heatstroke, shock, and seizure. The application has both tutorial and hands-on training components. We conducted a UX study by administering a questionnaire to participants. The UX of learning through the VR application was then compared to using a traditional e-book format. Results indicate that participants perceived stronger internal behavior control with the e-book but reported better confirmation, engagement, enjoyment, and intention to use when training with the VR system. Gender differences were also explored, revealing that female participants expressed greater interest in learning through the VR platform compared to male participants. These findings provide insights into the strengths and limitations of VR-based first aid training compared to traditional methods. Implications for the design and deployment of VR training systems are discussed, with a focus on optimizing the learner experience and learning outcomes.

In this paper, I developed a scenario-based admission management virtual reality (SAM VR) content for practical training for nursing students and verified the effectiveness. The SAM VR contents used in the study was developed by the researcher using Gear VR and smartphone according to the standard practical procedure suggested by the Korea Acreditation Board of Nursing Education and Evaluation. In the 30 experimental groups who received practical training using SAM VR contents, learning flow, learning confidence, and learning satisfaction increased statistically significantly after the practical training (p<.001). In the control group, who received practical training in the traditional way, learning confidence increased after the practical training (p<.005), but there was no change in learning flow and learning satisfaction (p>.005). It was verified that the SAM VR contents are effective practical education contents for nursing students' learning flow, learning confidence and learning satisfaction.

The system components and implementation methods to be considered when constructing a system for plant safety training in a virtual environment were classified according to plant characteristics. When constructing a safety training system based on VR, the necessary components may be different according to the characteristics of the plant, and the basic system components to be built according to the target plant are presented. In order to support the proposed system, we implemented a city gas governor safety training system, which is a relatively simple facility. Through this, we propose guidelines for the construction of a suitable VR-based plant safety training system in the plant to be applied.

In this paper, we will discuss planning and production of VR contents for effective racing drone steering training. In the real world, direct racing drone training training is obviously a space and economic limit. We propose through the production of VR-based drone infiltration action game as a solution to these limitations and try to improve effective drone handling ability. Especially, we designed the virtual reality contents in a similar environment by using the similarity of FPV goggles and HMD based VR, and designed virtual drones, maps and obstacles considering the characteristics of the structures used in racing drone and drone racing. Also, we tried to increase the user's immersion and presence by increasing difficulty level of obstacles.

National agencies and corporations are making a lot of efforts to educate mechanics from high school to university and enterprise training center to train as skilled mechanic. but the theoretical training using textbooks and the training using equipment not used in the field did not provide proper maintenance training. And education using special equipment or assuming dangerous situation was very dangerous, so we were carrying out education with video or photo. In recent, there have been a number of cases in which effective training simulations have been researched and developed in order to experience situations and solve problems safely through simulation from simple maintenance to special maintenance by combining VR and AR. This paper describes the comparative study of the existing APIs such as Danuri VR, DisTi Engine and Remote AR for general purpose AR/VR contents. We also proposed a AR/VR API based on Unity 3D Engine for AR/VR maintenance contents. The API can be used for maintenance contents developers efficiently.
