The Republic of Korea Army (ROK Army) is currently developing the Army Synthetic Battle Training System (ASBTS) by 2026 and will use it to advance division-level LVC integrated training. This study proposes a way to improve the effectiveness and efficiency of training by applying VR/AR technology to the ASBTS. To this end, we analyzed cases of VR/AR technology use in the defense field in advanced countries and the ROK military. As a result, we confirmed that the effectiveness and efficiency of training can be improved when the training system is converted to an immersive system. Accordingly, we selected and presented defense training subjects to be applied to VR/AR technology, considered the development direction for applying VR/AR technology to the ASBTS, and proposed a way to apply VR/AR technology to the ASBTS.

In this paper, we proposed a software framework structure to apply ORB-SLAM, the most representative of SLAM algorithms, so that map creation and location estimation technology can be applied through tethered AR glasses. Since tethered AR glasses perform only the role of an input/output device, the processing of camera and sensor data and the generation of images to be displayed through the optical display module must be performed through the host. At this time, an Android-based mobile device is adopted as the host. Therefore, the major libraries required for the implementation of AR contents for AR glasses were hierarchically organized, and spatial recognition and location estimation functions using SLAM were verified.

Smartphones provide users with environment for communication and sharing information and at the same time play an important role of mobile technology and mobile art development. Smartphone technology-related researches are being accelerated especially with the advent of mobile Augmented Reality(AR) age, but the studies on user participation that is essential for AR content industry were insufficient. In that regard, the assistance from mobile art area that has already developed these characteristics is essential. Thus, this article is to classify mobile art that has not been studied a lot domestically into feature phone usage and smartphone usage and to analyze each example case with the three most used methods. The usage of feature phones which use the sound and images of mobile devices can be divided into three: installation and performing methods, single channel video art method and five senses communication method. On the other hand, the usage of smartphones that use sensors, cameras, GPS and AR can be divided into location-based AR, marker-based AR and markerless AR. Also, as a result of examining mobile AR content utilization technology by industries, combined methods are utilized; tourism and game-related industries use location-based AR, education and medicine-related industries use marker-based AR, and shopping-related industries use markerless AR. The development of AR content industry is expected to be accelerated with mobile art that makes use of combined technology method and constant communication method through active participation of users. The future development direction of mobile AR industry is predicted to have minimized HMD, integration of hologram technology and artificial intelligence and make the most of big data and social network so that we could overcome the technological limitation of AR.

In this study, our primary focus was on preserving the unique characteristics inherent to the medium of printmaking art, such as cultural implications and formal features, during the digital transformation of traditional printmaking. We investigated methods to incorporate augmented reality (AR) technology into the creation process of traditional printmaking. To help understand the intended fusion of traditional printmaking art and AR technology in this digital transition era, we categorized AR artworks into four types and conducted an analysis of various AR artwork examples from across the globe. From this analysis, we derived the methodologies and design directions for combining AR technology with traditional printmaking. Moreover, we created an AR printmaking piece based on the author's artwork "Spring, Summer, Fall, Winter," thereby demonstrating the significant role AR technology can play in the evolution of printmaking. Through this research, we were able to verify the potential and value of AR printmaking as an immersive art form capable of providing a more expansive narrative.

The $Sr_{0.7}Bi_{2.3}Nb_2O_9$(SBN) thin films are deposited on Pt-coated electrode(Pt/Ti/$SiO_2$/Si) using RF sputtering method at various $Ar/O_2$ ratio. We investigated the effect of deposition condition(specially $Ar/O_2$ ratio) on the structural properties of SBN thin film. As $Ar/O_2$ ratio was increased, the peaks in the XRD pattern became more sharp. Also, the peaks(008)(115)(220) in 80/20 of $Ar/O_2$ ratio were suddenly appeared. The optimum of the rougness showed about 4.33 nm in 70/30 of $Ar/O_2$ ratio. The crystallinity of SBN thin films were increased with the increase of $Ar/O_2$ ratio. Also, Deposition rate of SBN thin films was about 4.17 nm/min in 70/30 of $Ar/O_2$ ratio. The capacitance of SBN thin films were increased with the increase of $Ar/O_2$ ratio.

Augmented Reality (AR) is a mix of the real world that is enhanced by virtual objects from computer-generated information. AR is currently used in a variety of information systems and library services. AR technologies are also being developed for today's children, who are digital natives and are exposed to various technologies even earlier. To assist librarians who need to accurately understand users' information needs and perceptions of the technology being used in their libraries, we conducted a study of AR perceptions among children. We conducted two online co-design sessions using "Would you rather?", a co-design technique that facilitates research into children's opinions. Through the co-design sessions, we found that children were psychologically wary about AR technology due to a lack of trust in the technology, and realism had a significant impact on these judgments. We also identified that children considered AR technology environments as an extension of the real world. Their real-world values directly influenced their perceptions of AR. This research provides insights into the wariness that libraries need to be aware of when developing AR content for children in the future, and how libraries can use AR as an educational tool.

Selecting promising technology is becoming more and more difficult due to the increased number and complexity. In this study, we propose hybrid AHP/DEA-AR method and hybrid AHP/DEA-AR-G method to evaluate efficiency of technology alternatives based on ordinal rating data collected through survey to technology experts in a certain field and select efficient technology alternative as promising technology. The proposed method normalizes rating data and uses AHP to derive weights to improve the credibility of analysis, then in order to avoid basic DEA models' problems, use DEA-AR and DEA-AR-G to evaluate efficiency of technology alternatives. In this study, we applied the proposed methods to clean technology and compared with the basic DEA models. According to the result of the comparison, we can find that the both proposed methods are excellent in confirming most efficient technology, and hybrid AHP/DEA-AR method is much easier to use in the process of technology selection.
