In this paper, we propose a study related to the development of a Digital-Twin platform using a smart factory based CPPS (Cyber Pysical Production System) using ICT (Information Communication Technology) technology. The platform developed through this study performs a 3D model simulation function in conjunction with P3R (Product, Process, Plant, Resource) including BOP (Bill of Process) management function from the preceding manufacturing process planning stage. In addition, we propose a digital twin platform that can predict production processes, equipment, layout, and production. The platform proposed through this paper proposes a feature that can manage the entire smart factory manufacturing process from the initial planning design stage to the manufacturing, production, operation, and maintenance stages.

It has recently been combined with advanced technologies such as AR and VR, and its application range is expanding to various forms of smart signage. However, until now, digital signage service that reaches us is installed in many floating populations such as bus stops, elevators, and banks and is used in the form of providing news, weather, and advertisements. In addition, large companies, government offices, and outdoor advertising companies occupy the market. The use of such services in small and medium-sized businesses and small retail stores is costly and expensive to manage. Also, it is difficult to generalize the market because services and solutions are being deployed in the market in the form of top-down. Therefore, in this paper, we proposed a digital signage system for transmitting a remote video advertisement that uses a show window in front of the store as a beam project screen for small retail stores, and can remotely set and manage and update it in OSGi service platform.

This paper is a study aimed at facilitating a comprehensive understanding of the music metaverse platform that will emerge in the era of Web 3.0 and exploring productive strategies for its construction. We examine the significance of the metaverse music platform from various perspectives and investigate the developmental process of digital music platforms from Web 1.0 to 3.0. Subsequently, assuming the emergence of metaverse platforms as a transition to Web 3.0, we align this transition with technological(VR technology, wearable devices, generative AI), cultural(digital avatars, fandom), and economic(NFT) discussions related to Web 3.0. These discussions are integrated with the developmental strategies of the metaverse music platform. Through this study, we hope to enhance the understanding of the metaverse music platform and provide insights into potential construction strategies.

Virtual reality seems to be the center of the next generation platform, which is founded on various engines that can easily make device progress and content. However, the interaction between virtual reality contents and users is thought of as relatively requiring technological advances. In this paper, we propose a technique to improve the interaction technique based on the case of Virtual Figure Model Crafting (VFMC) to analyze the problem of interaction caused by virtual reality contents. We introduced the concept of Head-Up Display (HUD) to present a more natural interaction method. The HUD is the digital visual interface of the aircraft. The advantage of HUD visual interface is to minimizes the user's visual movement by displaying the information of the scattered view to the forward direction of the pilot. In other words, we can reduce unnecessary left and right movements that make it is possible to expect an effect of reducing fatigue and increasing immersion.

본 논문에서는 제작한 가상현실 게임의 소개와 적용기술에 대해여 논한다. HTC VIVE를 이용하여 강력한 주요 게임 개발엔진 중 하나인 Unreal engine4를 이용하여 쉽게 접근 할 수 있는 VR 리듬게임 구현을 목적으로 한다. 플랫폼의 한계의 벗어나 HUD로 좀 더 현실감과 몰입을 요구하는 게임개발을 목표로 리듬감 증진 혹은 운동효과도 기대할 수 있다. 사운드 플러그를 이용하여 주파수별 스펙트럼을 시각화하여 재생되는 음원중 스펙트럼 값이 조건을 만족하면, 노트가 자동으로 생성되고 일정 시간이 경과한 후 사라지거나, 플레이어가 타격하여 점수를 획득 하는 방식으로 진행되며, 플레이어가 노트를 맞을 경우 체력값이 단계별로 낮아져 게임이 종료된다. 더 많은 곡과 맵을 추가하여 흥미소요를 늘릴 수 있으며, 단순타격이 아닌 조건이나 임무를 부여 다양성과 복잡함을 추가해 낮은 접근성과 높은 정복성을 가질 수 있다.

In this paper, we propose a platform for learning deboning technology of Korean beef through vr-based experiential learning. The Korean beef deboning process is not only a food ingredient that has represented Korea for a long time, but also an object with high traditional cultural value. However, due to the hard and dangerous work envrionment of the deboning field, the number of skilled dobiners is gradually decreasing. This study proposes a platform that can train these deboning technicians in virtual reality and covers applied technologies used. In particular, we discussed how processes such as bending, opening, and cutting are implemented during meat cutting, which is a very important part of deboning work. In the experiment, cutting work was performed based on actual meat modeling, and complete cutting was tested.

As the non-face-to-face situation continues for a long time due to COVID-19, the underlying technologies of the 4th industrial revolution such as IOT, AR, VR, and big data are affecting the metaverse platform overall. Such changes in the external environment such as society and culture can affect the development of academics, and it is very important to systematically organize existing achievements in preparation for changes. The Korea Educational Research Information Service (RISS) collected data including the 'metaverse platform' in the keyword and used the text mining technique, one of the big data analysis. The collected data were analyzed for word cloud frequency, connection strength between keywords, and semantic network analysis to examine the trends of metaverse platform research. As a result of the study, keywords appeared in the order of 'use', 'digital', 'technology', and 'education' in word cloud analysis. As a result of analyzing the connection strength (N-gram) between keywords, 'Edue→Tech' showed the highest connection strength and a total of three clusters of word chain clusters were derived. Detailed research areas were classified into five areas, including 'digital technology'. Considering the analysis results comprehensively, It seems necessary to discover and discuss more active research topics from the long-term perspective of developing a metaverse platform.

본 논문에서는 360도 카메라기반 식물 전자 상거래서비스 어플을 제안한다. 식물을 이용한 재테크 일명 "식테크"라고 불리는 재테크가 증가하고 있는 추세이다. 현재 다른 중고거래 플랫폼에서는 본 거래가 제안되어 있어 거래가 어렵고 일종의 재테크의 개념이라 전문적으로 거래하기 힘들다는 문제점이 있다. 이를 해결하기 위해 본 프로젝트에서는 실시간 차트를 활용하여 식물 거래가를 알려주고, 360도 카메라와 VR을 활용하여 식물의 육성일기 공유하여 어플 사용자들의 커뮤니티 장소가 되고, 은퇴 후 귀농을 하는 사용자에게는 식물을 잘 기르는 법의 정보를 알 수 있는 다방면에서 활용이 가능하여 여러 문제를 효율적으로 해결할 것으로 기대된다.

Recently, metaverse is rapidly expanding its area as a platform that can be applied to various fields. In particular, the function that allows many users to interact in a three-dimensional space allows VR/AR-based educational content to be used as a more advanced concept. Due to the nature of engineering education, it is often based on three-dimensional objects. In the case of a three-dimensional object, it is difficult to explain through two-dimensional videos or documents, and it becomes more difficult to express when the process of changing the object is included. The three-dimensional space of the metaverse can improve this difficulty based on real-time rendering. Another characteristic of engineering education is that there are many invisible elements. Although it is involved in the movement of objects due to electromagnetic fields, magnetic fields, and forces, it is the main reason for increasing learning difficulty because it is invisible. These problems can also help learning because they can be visually represented in the metaverse space. In this paper, the results of the establishment of the metaverse platform for engineering education and the real-time lecture contents produced based on it are described, and the applied results and lecture evaluation are discussed. Lectures using a total of 9 metaverse contents were conducted, and 90% of the positive lecture evaluation results were obtained.
