Silgyeong sansuhwa (Realistic landscape paintings) are drawn in Korea since 17th century. It has characteristics of more realistic description of landscape than painting from previous periods. Kim Hong Do's 'Haedong Myeongsan docheop (The album of paintings of famous mountains in Korea)' has been recognized as fine example of realistic description of geomorphic landscapes. Kim Hong Do and Kim Eung hwan did official travel to Gwandong and Geumgangsan area by order of King Jeongjo in 1788. As a result of that travel they draw about 100 piece of landscape painting. About 60 pieces of the paintings are still remaining. These are open to public by Korea National Museum in 1996. 14 pieces of painting, Daegwanryeong and Gangneung, Gyeongpo-dae, Hohae-jeong, Gahak-jeong, Cheonggan-jeong, Mun-am, Mangyang-jeong, Wolsong-jeong, Neungpa-dae, Naksan-sa, Mureung-gye, Gyejo-gul, and Hyeonjong-am, are analysed in this study. Coastal depositional landforms, like lagoon, sand beach and spit or barriers, erosional forms, like sea stack, sea cliff and sea cave, depicted in the paintings are analysed. In addition, structural landforms, colluvial landform and bedrock incision form by the running water in mountain area were analysed and weathered forms of granite and excursion to karst cave also discussed. It is found that sea arch in the printing destroyed since 1788, though exact position and reason is still unknown. There are strong need for discovery and identification of geomorphic landscape resources, for applied geomorphological studies and for prepare educational materials for non-face-to-face education. It also be emphasized that it can be used of the course work materials for future education using augmented reality and virtual reality technology.

The purpose of this study is to explore the potential of digital graffiti as a new creative tool in fashion through analysis of its expressive features and methods merged in fashion. The results from the analysis of fashion cases using digital graffiti may be summarized as follows. First, 'Mixing of Materials and Non-materials' matched immaterial lights and images with physical clothing materials and space, effectively expressing imaginary spheres that were not expressible with the existing materials. Second, 'Fantastic Storytelling' expressed theme such as 'Sun', 'UFO', 'Science Fiction Film', 'Fantasy Fairy Tale', and 'Universe' through lasers, lights, augmented reality and LED graffiti. Third, 'Convergence with Human and Digital Media' accentuated the active participation of spectators thereby causing human and digital media to interact with each other. Designer's ideas and unexpected responses of spectators realized various digital graffiti effects, which came across by sheer chance. Fourth, 'Utilizing of Site-Specificity' met with the best results when the digital graffiti was expressed in context of a place or location where fashion performance is taking place. Fifth, ' Playfulness by Consumer Participation' intended to induce voluntary participation from consumers by providing the fashion digital graffiti as play tools, and created new fashion digital graffiti or altered existing stereotypes, thereby invoking new visual and tactile experiences. Likewise, today's digital graffiti are emerging in various fields, and the trend of fashion-digital graffiti integration has already created interesting works.

In this paper, we examined the research trends and characteristics related to the metaverse in global journals published between 2000 and 2022 from the Web of Science database. The analysis included descriptive statistics, multidimensional scaling, keyword network analysis, and visualization. In addition, semantic network models were constructed, and centrality (betweenness and degree) analysis was performed using R and KH coder in two separate categories based on the trends and aspects of the publication: analysis period 1 (Jan 2000 to Dec 2020) and period 2 (Jan 2021 to Jun 2022). The results showed that the recent global research trends related to the metaverse could be quantitatively characterized using the semantic network analysis. Also, the results could be applied to suggest future research topics in the field of metaverse based on quantitative and empirical data.

The 3D position of pedestrians is a physical quantity used in various fields, such as automotive navigation and augmented reality. An inertial navigation system (INS) based pedestrian dead reckoning (PDR), hereafter INS-PDR, estimates the relative position of pedestrians using an inertial measurement unit (IMU). Since an INS-PDR integrates the accelerometer signal twice, cumulative errors occur and cause a rapid increase in drifts. Various correction methods have been proposed to reduce drifts. For example, one of the most commonly applied correction method is the zero velocity update (ZUPT). This study investigated the characteristics of the existing INS-PDR methods based on shoe-mounted IMU and compared the estimation performances under various conditions. Four methods were chosen: (i) altitude correction (AC); (ii) step length correction (SLC); (iii) advanced heuristic drift elimination (AHDE); and (iv) magnetometer-based heading correction (MHC). Experimental results reveal that each of the correction methods shows condition-sensitive performance, that is, each method performs better under the test conditions for which the method was developed than it does under other conditions. Nevertheless, AC and AHDE performed better than the SLC and MHC overall. The AC and AHDE methods were complementary to each other, and a combination of the two methods yields better estimation performance.

Purpose - As the scope of existing digital transformation expanded to various degrees, the Fourth Industrial Revolution came into being. In 2016, Klaus Schwab, Chairman of the World Economic Forum (WEF), said that the new technologies that lead the fourth industrial revolution are AI, Block chain, IoT, Big Data, Augmented Reality, and Virtual Reality. This technology is expected to be a full-fledged fusion of digital, biological and physical boundaries. Everything in the world is connected to the online network, and the trend of 'block chain' technology is getting attention because it is a core technology for realizing a super connective society. If the block chain is commercialized at the World Knowledge Forum (WKF), it will be a platform that can be applied to the entire industry. The block chain is rapidly evolving around the financial sector, and the impact of block chains on logistics, medical services, and public services has increased beyond the financial sector. Research design, data, and methodology - Figure analysis of data and social science analytical software of IBM SPSS AMOS 23.0 and IBM Statistics 23.0 were used for all the data researched. Data were collected from hotel employees in China from 25th March to 10th May. Results - The purpose of this study is to investigate the effect of the block chain characteristics of the existing hotel reservation system on the intention to use and to examine the influence of the block chain characteristics of the hotel reservation system on the intention to use, We rearranged the variables having the same or similar meaning and analyzed the effect of these factors on the intention to use the block chain characteristic of the hotel reservation system. 339 questionnaires were used for analysis. Conclusions - There are only sample hotel workers in this study, and their ages are in their 20s and 30s. In future studies, samples should be constructed in various layers and studied. In this study, the block chain characteristics are set as five variables as security, reliability, economical efficiency, availability, and diversity. Among them, Security and reliability made positive effects on the perceived usefulness. Also, security and economics did on the perceived ease. Availability and diversity did on both perceived usefulness and perceived ease. Perceived ease did on perceived usefulness. And perceived ease and perceived usefulness did on user intent. But security and economics did not on the perceived usefulness

This article aims to explain the concept and characteristics of the 'Intelligent Science Lab', which is being promoted nationwide in Korea since 2021. The Korean Ministry of Education creates a master plan containing a vision for science education every five years. The most recently announced '4th Master plan for science education (2020-2024)' emphasizes the policy of setting up an 'intelligent science lab' in all elementary and secondary schools as an online and offline space for scientific inquiry using advanced technologies, such as Internet of Things and Augmented and Virtual Reality. The 'Intelligent Science Lab' project is being pursued in two main directions: (1) developing an online platform named 'Intelligent Science Lab-ON' that supports science inquiry classes, and (2) building a science lab space in schools that encourages active student participation while utilizing the online platform. This article presents the key features of the 'Intelligent Science Lab-ON' and the characteristics of intelligent science lab spaces newly built in schools. Furthermore, it introduces inquiry-based science learning programs developed for intelligent science labs. These programs include scientific inquiry activities in which students generate and collect data ('data generation' type), utilize datasets provided by the online platform ('data utilization' type), or utilize open and public data sources ('open data source' type). The Intelligent Science Lab project is expected to not only encourage students to engage in scientific inquiry that solves individual and social problems based on real data, but also contribute to presenting a model of online and offline linked scientific inquiry lessons required in the post-COVID-19 era.
