With increasing interest in key areas of the 4th industrial revolution such as artificial intelligence, deep learning and big data, scientific approaches have developed in order to overcome the limitations of traditional decision-making methodologies. These scientific techniques are mainly used to predict the direction of financial products. In this study, the factors of apartment prices, which are of high social interest, were analyzed through SOM. For this analysis, we extracted the real prices of the apartments and selected a total of 16 input variables that would affect these prices. The data period was set from 1986 to 2021. As a result of examining the characteristics of the variables during the rising and faltering periods of the apartment prices, it was found that the statistical tendencies of the input variables of the rising and the faltering periods were clearly distinguishable. I hope this study will help us analyze the status of the real estate market and study future predictions through image learning.

Most universities are attempting educational innovation through multidisciplinary approaches, such as interdisciplinary programs and convergent majors, to nurture convergent talents in the era of the 4th Industrial Revolution. The purpose of this study is to identify the priorities of the educational needs of students who complete the interdisciplinary program and to find its effective operation plan. For this purpose, research was conducted to search for the university-level support required to vitalize the interdisciplinary program by doing focus group interviews with students who have participated in the interdisciplinary program. And the final priority was derived by applying the t-test, Borich's need assessment model, and The Locus for Focus Model, using online research. As a result of the analysis, 'formation and operation of dedicated organizations' and 'dedicated classrooms and practice rooms' were deduced as factors to be considered as a top priority, 'curriculum specialization,' 'interdisciplinary program scholarship support,' 'interdisciplinary program promotion,' and 'assignment of dedicated teaching assistants' were derived as secondary consideration factors. Based on these research results, a plan of vitalizing the educational needs for the interdisciplinary program at university and its implications were suggested.

The purpose of this study is to find out the spatial expression characteristics of Philipstock from a heterotopic perspective in the background of the times of modern people struggling to live in the era of an infectious disease called COVID-19 along with the era of the 4th industrial revolution. As for the research method, a total of 11 places were selected, focusing on the completed works of interior space from 2015 to the present, when they are more active after retirement, to find out the characteristics of spatial expression through literature and case studies. As a result, the spatial expression characteristics of narrative that only space has were the most frequent, and it was found that the characteristics of imaginary space and fantasy, which are the form of overlapping time to express a place, were interrelated. Philip Stock's design method, which uses narrative, fantasy, and imaginary spatial characteristics, can be seen as sufficiently representing heterotopic characteristics and can be used as another design methodology when designing a new space.

The VR / AR market has grown significantly due to the development of virtual reality and augmented reality in the core technology field of the 4th Industrial Revolution. Since VR is basically focused on space and time, and the human brain is very sensitive to temporal events, it is important to make accurate I / O interface technology, one of the virtual reality technologies, not to affect the brain's cognitive ability. VR depends on the technology of the hardware such as the display and the sensor for biometric signal recognition. In this paper, in order to prevent the sensitive brain from affecting the sensor device in consideration of hardware dependency of VR, it is necessary to make various corrections to lower the motion to photon (MTP) to 20m / s or less experiments on the method and filtering were carried out.

This study aims to measure Korea's global competitiveness in intelligent information technology, which is the core technology of the 4th industrial revolution. For analysis, we collect patents of each field and prior patents cited by them, which are applied at the U.S. Patent Office (USPTO) between 2010 and 2018 from PATSTAT Online. A global knowledge transfer network was established by grouping citing- and cited-relationships at a national level. The in-degree centrality is used to evaluate technology acceptance, which indicates the process of absorbing existing technological knowledge to create new knowledge in each field. Second, to evaluate the impact of existing technological knowledge on the creation of new one, the out-degree centrality is investigated. Third, we apply the PageRank algorithm to qualitatively and quantitatively investigate the importance of the relationships between countries. As a result, it is confirmed through all the indicators that the AI sector is currently the least competitive.

In this paper, we propose a Leveled Micro-Degree Job Competency Certification Model that considers the level of the job based on the job defined in the NCS. There is a mismatch of manpower due to the problem of university education that cannot keep up with the rapidly changing technological environment caused by the 4th Industrial Revolution. The Nano-Degree and Micro-Degree systems designed to solve this problem are used for job competency certification of cyber security personnel. NCS sub-categorized job field is defined as Micro-Degree and detailed job by ability unit is defined as Nano-Degree, the level of the ability unit defined by level is equally applied to the Micro-Degree. And it is a system that certifies the job competency corresponding to the degree-based university academic background. By applying this system to the curriculum of Cyber Security School, Yeungnam University College, we proposed a method to configure the Nano-Degree course based on NCS duties. The method proposed in this paper can be used as a method for verifying job competency of Nano-Degree and Micro-Degree, which are recently introduced by many universities.

Interest and investment in drones that apply the concept of the 4th industrial revolution and ICT convergence advanced technology are continuing. The purpose of drone operation has been widely spread from the initial military use to the use of various industries such as construction, forestry, facilities, and agricultural support. In these industries, the training of pilots who can actually operate drones is increasing centering on the qualification system. However, the detailed standards including the training place, training place, educational environment, and education method for nurturing pilots are ambiguous, so the education through the oral instruction of the training instructor is continuing at the drone training site. In order to solve this problem, this study conducted a study on a dual control platform in which a training instructor could directly intervene in the pilot's flying drone to execute a map in order to improve the quality of synesthesia, which is essential in the field.
