The 21 Century is definded as an age of culture or image characterized by the fact, that modern society are being overwhelmed with virtual reality, that is full of visual images. The cultural concentration on the visual image and the excessive tendency to attend it become not only today but also ever as the leading style of culture. Nevertheless, it is particularly noteworthy that the visual image has become so one of the basic conditions of modern society, that one holds it as the society of the spectacle. So can the problem of seeing that resulted from the oculocentric culture, that is the problem of the fundamental relationship between the world and the eyes of human beings, be examined in the phenomenological sense. For this study, I believe that 『Phenomenologie de la Perception』 of Merleau-Ponty provides a important approach. The theme of this study is to refer, first, how man has dealt with the seeing in the history of philosophy, such as Plato, Kant, and Merleau-Ponty, who although not the anti-oculocentricism, but also makes serious reflection about an excess of visual images. Second, it is to explain what characteristics and problems are located in these considerations, and thirdly, it must be brought into the light, what is the essence of the seeing with regard to the beauty, the truth and the morality.

Recently, the frequency and range of algae occurrence in major rivers and lakes are increasing due to the increase in water temperature due to climate change, the inflow of excessive nutrients, and changes in the river environment. Abnormal algae include green algae and red algae. Green algae is a phenomenon in which blue-green algae such as chlorophyll (Chl-a) in the water grow excessively and the color of the water changes to dark green. In this study, a 3D virtual world of digital twin was built to monitor and control water quality information measured in ecological rivers and lakes in the living environment in real time from a remote location, and a sensor measuring device for water quality information based on the Internet of Things (IOT) sensor. We propose to build a smart water environment service platform that can provide algae warning and water quality forecasting by predicting the causes and spread patterns of water pollution such as algae based on AI machine learning-based collected data analysis.

This study aims to explore the direction of Christian public practice in the post-COVID era, seeking to overcome the uncanny feeling caused by increased division and exclusion during the pandemic period. Firstly, we will investigate the unequal impact of COVID-19 on the labor market and examine ways to achieve economic justice in the post-COVID era. Subsequently, we will deliberate the role of Christianity in establishing publicness in the digital world and virtual spaces. Finally, viewing COVID-19 as a catastrophe caused by an anthropocentric worldview and exploitation driven by greed, we will explore the tasks of Christianity to overcome the crisis of the Anthropocene. Christian public practice should fulfill its mission of care and stewardship not only in social context but also in an ecological dimension. The author proposes "planetary citizenship education" for a harmonious relationship between human species and the Earth they inhabit.

The key success factors for Franchise Enterprise as a virtual company which is established based on franchise system are the competitiveness of sub-systems in franchise system such as franchisor, franchisee, vendor(supplier), and customer, and to sustain the symbiotic relationship among sub-systems. In this regard, evaluating franchise system is considered to be implemented in different contexts and methods comparing with extant evaluation system in franchise business which is more focused on the relationship between franchisor and franchisee. The flagship role of establishing franchise system is to be franchisor system, however, the symbiotic relationship among other sub-system including franchisee, vendor, and customer leads to successful Franchise Enterprise. The purpose of this study is to research existing evaluation systems for franchise business and to explore the model of evaluating franchise system, what is called, "Symbiosis Index".

An elevator is a mechanical and electronic device composed of about 20,000 various parts, and is systematically operated with a close relationship with each other. By intuitively understanding this complex elevator structure and efficiently recognizing the operating model, it will be possible to increase the understanding of the elevator system and the efficiency of maintenance. The existing elevator management system is a process of collecting and understanding information based on data generated from elevators, and has a structure that lacks efficiency in expressing and managing real-world information during elevator maintenance. Therefore, this paper proposes a simulator framework that can operate efficiently based on the actual elevator model. By constructing the recognition of specific objects through a 3D-based service model and visualizing the operation process, it will be possible to enhance the understanding of the structure and operation required for elevator operation. To this end, the core components of the elevator system are identified, the relationship between them and the operating method are visualized, and a simulator is implemented. Based on this, it will be possible to provide a realistic information management and operating environment in virtual space and real platform.

When conducting metaverse-based logistics education, educational, entertainment, and sense of reality were presented as preceding factors as factors that content should have, and the effect on learner satisfaction by mediating learner participation was verified. The results and implications are as follows. First, educational, entertainment, and presence were found to be important factors that can improve learners' participation. Since it is a content provided as part of university education, it can be expected that the educational value will be the highest, but entertainment has been identified as the most influential variable. Therefore, in order for metaverse-based logistics education to induce learners' participation, it is necessary to plan contents that students can enjoy and enjoy. Second, it was found that learner participation has a positive effect on learning satisfaction. Although it is a virtual world, if it is real and you can interact with other learners, you will be satisfied with your learning. Therefore, it is necessary to develop contents that can induce learners' participation in order to continuously provide learning satisfaction when providing metaverse-based logistics education.

This study aims to rediscover the industrial value of a borderless service in the hyper-connected era by producing fashion content at the forefront of the cultural industry as XR content and contributing to developing fashion content for edutech. The research method employed design aesthetic theory, while the empirical proposal utilized scientific knowledge information to build a framework for 3D convergence content. The characteristics of fashion content exhibitions that apply the neumorphism technique are as follows: The first is a virtual space that produces clothing culture by type. Africa, where dyeing and crafts are developed, selects a product-oriented exhibition type; Asia, where weaving and textiles are excellent, selects a random movement type; and Europe, where the evolution of clothing design over time is evident, selects a guided movement type to create a three-dimensional fashion edutech. The goal was to produce content. The second is creative reproducibility, which combines a new fashion design that embraces the aura of the original with a trendy sense. The realistic folk costume style of the original allowed for its implementation in the AR exhibition space using historical traditional style techniques such as weaving and textiles. The third is building organic, modular content. By designing and then saving/editing/arranging the basic VP zone for each style, learners and instructors can freely edit the content for each fashion class topic and create various presentations to ensure that it functions as non-face-to-face edutech content around the world.

In this paper, we propose a solution to apply a proximity voice dialog system to voice dialog technology, one of the interaction systems in multimedia environments. A voice dialog between multiple users in a multimedia space is designed by adjusting the volume of the voice according to the distance between the user avatars and muting the user who is beyond the audible distance. The main feature of this research is a reliable UDP-based active server system that delivers low-quality voice data to users who are far away based on distance and does not transmit voice data to users who enter the inaudible area for economic development. The performance of the proposed system was measured in a previously completed project based on the Unity game engine, and it is expected that the system proposed in this research will be actively used in environments that provide interaction between multiple users such as met averse content and real-time battle action games.

This study was conducted with the purpose of providing suggestions for improvement through a comparison and analysis of the services of the U.S. National Library of Medicine, the world's largest medical library, and the National Center for Medical Information and Knowledge, Korea's national medical library. Core services that need to be improved are topic-specific services, community services, services by user type, educational services, technology, facility/space services, research support services, and marketing and public relations and cooperation services. Specialized libraries are also increasingly interested in topic-specific services and public services. Efficiency in access through services for each type of user is needed, and various types of educational services that do not limit the target audience are also needed. Marketing through AI, virtual reality, and technology, facility, and space services to support the disabled, research support services centered on research ethics, research grants, and programs, and collaborative services with domestic and international libraries, academic societies, institutions, and local communities in other related fields and publicity are also needed.
