최근 가상현실과 공간에 대한 다양한 연구들이 진행되면서 메타버스(Metaverse)를 중심으로 다양한 연구들이 진행중에 있다. 본 연구는 음악을 정량화하여 발생한 데이터를 이용하여 다양한 가상의 도시공간을 생성하는 작업을 진행한다. 이렇게 생성된 작업은 하나의 음악을 2-3명의 연주자가 연주한 내용을 바탕으로 진행이 되며, 분석 방법은 기존 연구 중 하나인 '뮤직 스카이라인(Music Skyline)'과 '크레페(CREPE)' 등의 방식을 통해 이루어지게 된다. 향후 추가 연구로서 이러한 부분들이 보완되고 개선된다면, 다양한 음악 정보를 활용한 자신만의 도시를 컴퓨터 기술이 아닌 음악 작곡만으로도 가능하도록 플래폼화 하고, 그 근거를 찾아내는데 많은 노력이 필요할 것으로 보인다.

최근 취향 관심사를 기반으로 한 소모임 플랫폼 수요가 높아지듯, 대학 내외의 사회 전반에서 수준 높은 네트워킹에 대한 욕구가 강한 상황이다. 나아가, 교육 환경, 거주 지역, 개인의 성향 등의 변인들이 성장의 주요 발판이 될 인적 자원을 만드는 데에 지대한 영향을 끼친다는 점에서, 진입 장벽을 낮출 서비스에 대한 니즈가 존재한다. 한편, 기존의 플랫폼은 대학 동아리 및 소모임 활동을 분산적으로 취급하며 총괄하지 못한다. 따라서, 본 논문은 기존 플랫폼의 문제점을 개선한 메타버스 웹 플랫폼인 클러버스(Clubverse)를 소개한다. 이는 대학 내 동아리 간의 소통 및 외부 업체와의 연계를 제고하고 성장기회를 공평하게 분배해 변화에 대비할 수 있는 가능성을 지닌다.

As a result of the study, the poorest keywords were information, big data, management, policy, government, law, and smart. In addition, as a result of network analysis, related research was being conducted on topics such as data industry policy, data governance performance, defense, governance, and data public. The four topics derived through topic modeling were "DG policy," "DG platform," "DG in laws," and "DG implementation," of which research related to "DG platform" showed an increasing trend, and "DG implementation" tended to shrink. This study comprehensively summarized data governance-related studies. Data governance needs to expand research areas from various perspectives and related fields such as data management and data integration policies at the organizational level, and related technologies. In the future, we can expand the analysis targets for overseas data governance and expect follow-up studies on research directions and policy directions in industries that require data-based future industries such as Industry 4.0, artificial intelligence, and Metaverse.

In this paper, we describe the process and method of converting tens of TB of time-varying AMR (adaptive mesh refinement) volume data generated as a result of numerical model simulation into optimized data that can be used for various XR devices. AMR volume data is a useful data format for complex modeling and simulation, and it can efficiently express materials such as star clusters and gases that exist in the very wide outer space used in this study. we analyzes the metadata of AMR data, samples it at low resolution, optimizes information in important areas, and converts it into a data set that can be used even on relatively low performance XR devices. Finally, we introduces how the optimized data was utilized and visualized through the development of immersive XR content using the data set.

3D reconstruction is important issue in many applications such as Augmented Reality (AR), eXtended Reality (XR), and Metaverse. For 3D reconstruction, depth map can be acquired by stereo camera and time-of-flight (ToF) sensor. We used both sensors complementarily to improve the accuracy of 3D information of the data. First, we applied general multi-camera calibration technique which uses both color and depth information. Next, the depth map of the two sensors are fused by 3D registration and reprojection approach. The fused data is compared with the ground truth data which is reconstructed using RTC360 sensor. We used Geomagic Wrap to analysis the average RMSE of the two data. The proposed procedure was implemented and tested with real-world data.

In today's modern fashion industry, along with the Fourth Industrial Revolution, the digital fashion industry using new technologies such as AR (Augmented Reality), VR (Virtual Reality), and Metaverse is gradually expanding. Accordingly, in the field of fashion design education, a new form of fashion illustration using VR technology is attracting attention as a new expression method. Recently, the use of digital tools such as iPads is gradually increasing in the field of education at universities majoring in fashion design, and students' interest in new digital tools is continuously increasing in the process of fashion illustration work. Therefore, this study implements fashion illustration using VR technology, which has been commercialized and popularized in the fashion industry, analyzes the differentiated characteristics compared to fashion illustration completed with iPad, and explores the possibility of using VR technology for fashion illustration as a new expression tool. We looked at the limitations. Through this study, it was found that VR is a positive help to fashion illustration to express the conception and overall connectivity in the three-dimensional aspect of fashion design, and the iPad was found to be suitable for specific and delicate fashion illustration expression. The results of this study are intended to provide basic data for fashion illustration education that can increase students' interest and achievement.

Currently, the domestic traditional market has not escaped the swamp of stagnation that began in the early 2000s despite various projects promoted by many related players such as the central government and local governments. In order to overcome the crisis faced by the traditional market, various R&Ds have recently been conducted on how to build a smart traditional market that combines information and communication technologies such as big data analysis, artificial intelligence, and the Internet of Things. This study analyzes various previous studies, users of traditional markets, and application cases of ICT technology in foreign traditional markets since 2012 and proposes a model to build a smart traditional market using ICT technology based on the analysis. The model proposed in this study includes building a traditional market metaverse that can interact with visitors, certifying visits to traditional markets through digital signage with NFC technology, improving accuracy of fire detection functions using IoT and AI technology, developing smartphone apps for market launch information and event notification, and an e-commerce system. If a smart traditional market platform is implemented and operated based on the smart traditional market platform model presented in this study, it will not only draw interest in the traditional market to MZ generation and foreigners, but also contribute to revitalizing the traditional market in the future.

2023 년 워크넷 구직자 데이터에 따르면 취업 취약 계층은 46.4%를 차지하며, 2019 년 KOSIS 국가 통계 포털에 따르면 취업 기관 및 프로그램 이용 경험이 없는 자는 전체의 93.7%를 차지한다. 이러한 현황은 대면 프로그램 부담과 정보 부족이 원인으로, 취업 기관 및 지원 프로그램의 활용도가 낮음을 의미한다. 일자리 및 자격증 등의 정보를 각각 찾아야 하는 불편함과 대면 활동 부담, 및 구직자 간의 정보 공유 어려움 등이 문제가 된다. 이를 해결하기 위해 웹 프로그램을 통해 사회적 취약 계층인 경력 단절 여성, 노인, 청년에게 구직 관련 정보를 제공하고 메타버스 가상 공간에서 다양한 활동을 통해 취업 취약 계층에게 적극적인 도움을 제공하는 서비스를 제안한다.

Immersive contents is content that provides a realistic experience by maximizing the user's five senses, and includes virtual reality, augmented reality, and mixed reality. In order to provide a sense of reality to users in immersive content, it is necessary to provide realistic visual images, hearing, and touch. However, due to the rapid change in the environment for developing immersive content, experts in training human resources are having difficulties in designing the curriculum. In this study, we propose a series of educational courses that use drones to acquire and process real-world measurement data and apply the derived data to VR, AR, and MR to help experts in training immersive content develop talent. The design of training process composes through demand survey and analysis of companies, students, and local communities. This study can be a useful resource for education experts who want to train immersive contents manpower.
