In the era of the 4th industrial revolution represented by AI technology, various AI education is being conducted in the education field. However, AI education in the educational field is mostly one-off project education or teacher-centered education. In order to practice student-centered, field-oriented education, an artificial intelligence education program was developed based on design thinking. The AI education program based on design thinking will improve understanding and ability to use AI through the process of solving everyday problems with AI, and will develop the ability to create new values beyond understanding AI. It is expected that various AI education will take place in the educational field through design thinking-based artificial intelligence education programs.

Recently, demand for smart factories is increasing in response to the era of the 4th industrial revolution. Smart factory is basically a manufacturing industry based on massive data, which requires IT services for processing a lot of data, which is accelerating the construction of data centers. Data center computing equipment requires a different approach from the cooling technology of general facilities in terms of heat load and usage time. This study investigates the factors to be reviewed in the recent data center cooling system design and technological change trends, compares and reviews various technological methods for facility configuration of case companies, derives the design decision process, and draws up a conceptual design corresponding to the conclusion.

The Internet of Things plays a role as an important element technology of the 4th Industrial Revolution. This study is currently developing intelligent cars with IT technology, and is at a time when the development of intelligent cars is active and network data communication is possible. However, security solutions are needed as security is still at a weak stage, which can be threatened by intrusions into the network from outside. In this paper, in order to improve security of intelligent cars without causing security problems, we will apply blockchain technology, propose biometric authentication techniques using users' biometric information, and continue to study them in the future.

With the continuous increase of the senior population, it is necessary to introduce the 4th industrial revolution applied technology into the health and welfare field. In addition, a senior emergency management system centered on Nono Care is established due to the shortage of young people, which requires strategization of a welfare delivery system in which senior colleagues notify emergency relief facilities directly in case of an emergency. In this paper, senior emergency management system is designed to collect and analyze individual activities and inactivity information through senior self-learning through smartphone app and to predict emergency situations with voice and image registration information through smartphone app menu.

This paper aims to develop a VR device prototype for reducing eye fatigue. As VR devices become popular, it is hoped that many cases of eye fatigue will be reported, and that the problems of VR devices will be corrected and repaired for a better future so that the fast speed and dynamic environment of 4th industrial revolution can be enjoyed with ease. In this paper, VR devices with a description of VR devices, eye fatigue related cases, time-out sensor for reducing eye fatigue, and eyeball massage functions were designed, and a VR device prototype was developed. These features can help reduce fatigue even if used for long periods of time by blocking electromagnetic waves harmful to the human body, and the future of VR could develop in the future.

The purpose of this study was to assess the implications for Daejeon's business management by analyzing the impact on the management performance of human solidarity among CEOs of small and medium venture companies in Daejeon. From 20th March to 20th May 2018, 212 questionnaires were collected from CEOs of small and medium-sized venture companies in Daejeon for this study and verified using the SPSS statistics Analysis Program. As a result, the study confirmed that the "work" and "school" connection factors have positive effects on securing government projects, improving business management, acquiring the necessary information for business growth, and securing competitiveness in 4th industrial revolution era. On the other hand, the "Region or Kin-group" connection factor does not affect the management performance. The following implications were derived fromthese studies on sustainable growth and development of business in Daejeon. First, it requires a higher level of the CEO solidarity. Second, efforts aimed at building mutual trust among CEOs in Daejeon are needed to develop close relationships and strong connections. Third, each operating association established in Daejeon needs to develop various programs for building relationships among CEOs and operate programs to increase the chances of contact.

With the 4th Industrial Revolution and the development of technology, markets of the VR&AR have increased. Also due to COVID-19 pandemic, demands for a digital environment were required because of physical space constraints. Firms are trying to solve this problem by using Metaverse platforms. However, with markets such as Metaverse, VR, AR, and Digital Twins are expanding, prior research on Metaverse definition or classification system is insufficient. Based on understanding VR&AR, Digital Twin, this study established a Industry-Service classification for Metaverse by defining Case studies on Metaverse and through prior research. And by Industry-Service classification for Metaverse this paper propose Metaverse Industry-Service Matrix to analyze the trend and possibility of Metaverse Platform

With the 4th Industrial Revolution, VR/AR technology is developing, and since COVID-19, the use of VR/AR technology is increasing and is being used in various environments. In particular, AR technology can be used in various educational fields and the perception of VR in the educational field and learning satisfaction, problem-solving ability, and self-directed learning ability when using VR were analyzed. It was analyzed that perception of VR and learning satisfaction had a significant correlation at the significance level of 0.001, and problem-solving competency had a significant correlation between learning satisfaction and self-directed learning ability at the significance level of 0.05.

Intelligence Home and Home Automation, which attracted attention before Smart Home, caused inconvenience to users by focusing on applying cutting-edge technologies to homes, and failed to popularize them due to lack of unemployment efficiency. However, with the 4th Industrial Revolution, various services using technologies related to big data, artificial intelligence, and the Internet of Things are increasing, and the rate of smart home services that operate, manage, and automate products at home is gradually increasing. In line with this trend, this paper implements a program app that can connect, manipulate, and manage products using MQTT server, Django web framework, and WIFI communication module.

After Satoshi Nakamoto published 'Bitcoin: A peer-to-peer electronic cash system' in 2008, Blockchain has been GPT (General Purpose Technologies) that affect the whole cycle of the $4^{th}$ Industrial Revolution. This study attempted to identify the innovativeness of Blockchain. Because of Blockchain's ambidextrous characteristics, Blockchain has two kinds of innovativeness, technological innovation by physical technology and social innovation by social technology. Thus, this study will be useful to increase understanding and establishing strategy for Blockchain.
