The human genome project decoded 99% of human genes for $ 3 billion by 1990-2003. However, as many studies on genes have progressed, it has become clear that there are many cases where diseases occur without structural alteration of genes. The latest study, Epigenetics, has come up with the answer to this problem. The famine that hit Jeju until 1670-1795, the ban on the exclusion of Jeju Island to the outside 200 years of suffering, and in 1948, one third of the citizens were killed by the 4.3 incident generate Epigenetic. It has been shown in the world history science that starving-stress can be manifested as obesity and disease in progeny due to hereditary phenomena. 5G-based healthcare IoT technology can be used for the treatment of obesity by enabling Epigenetic analysis of this phenomenon.

NFT art is a new art formed based on NFT technology. This is attracting great attention in the existing art world and art market. Therefore, it is required to analyze whether NFT art can establish itself as a new area of art. Therefore, the formation and development process of NFT art is analyzed from the perspective of Actor-Network Theory of Science and Technology and Studies, and the case of NFT artist 'beeple' is a representative example. It also discusses the artistic value of NFT art and its relationship with traditional art networks based on the aesthetics of science and technology researcher Graham Harman. In particular, it analyzes the future and genre sustainability of NFT art through the case of NFT project "Cryptopunks" and "PUNKISM" advocating a new art genre. By analyzing NFT art with ANT, I would like to raise a technical, aesthetic, and philosophical questions and propose a positive prospect as a new art genre.

As the need for software development manpower increases, various educational programs appear and the popularity of bootcamp style education program for software development increases. However, despite the operations and forms of bootcamp education programs are completely different from the existing software development education programs, there is a lack of research in understanding bootcamp as a software education program. Therefore, this study tried to derive the core elements of the education program through a case study on bootcamp software developer education program. After conducting interviews of 7 members who have completed a series of bootcamp software developer education program X, seven characteristics of bootcamp-type software development education program were derived: intensive theory education, sense of growth and achievement, team project-based learning, community characteristics, peer pressure, stress and fatigue due to short-term learning, and contact-free specialty. Based on the derived characteristics, the advantages and improvements of bootcamp-type education were described, and the direction of the bootcamp-type education program for software developer was discussed.

Recently, as per a representative education method to develop core capabilities (such as critical thinking, communication, collaboration, and creativity) problem based learning (PBL) has been widely adopted in universities. Two important features of PBL are 'collaboration between team members' and 'participation based self-directed learning'. These two features should be satisfied in online education, although it is difficult due to the limitation on space and time in the COVID-19 pandemic. This paper presents a new design of PBL class in Metaverse, based on improving the online PBL class operated in the previous semesters in the H university. In the proposed PBL class, students are able to display materials (e.g., image, pdf, video files) in 3D virtual space, that are related to problem solving. The 3D virtual space is called gallery in this paper. The concept of gallery allows for active participation of students. In addition, the gallery can be used as a tool for collaborative meeting or for final presentation. If possible, the new design of PBL class will be applied and its effectiveness will be analyzed.

As the era of metaverse approaches, there are challenges that need to be solved. Among them, 'cyber motion sickness' is a representative problem from 2016;when VR technology began to attract attention. According to the theory of sensory conflict, motion sickness is caused when the perceived direction of motion information and the expected value are not the same. The paper was written to theoretically explore the relationship between brain cognition and cyber motion sickness, and to prove the effect of user immersion on motion sickness symptoms based on this. Through the SSQ experiment, it was found that the rotation value of the camera aggravates the symptoms of cyber motion sickness and can alleviate cyber motion sickness by increasing the immersion of the game by giving the viewer visual and shift missions to solve. This study was conducted to solve the problem of cyber motion sickness during the process of developing the VR rhythm game "beatale", and it is expected to be the basis for improving cyber motion sickness not only in the development of the project but also in the production of VR contents in the future.

Due to COVID-19, organizations are rapidly changing the way they work by providing telecommuting and flexible work, and by expanding Smart Work spaces. In a Smart Work situation, workers have improved their job autonomy to choose their work methods, hours, and places. However, previous studies do not reflect the Smart Work situation and there are limitations to still using the previous job autonomy concept and measurements. To overcome these problems, this study derived job autonomy types such as methods, scheduling, criteria, time, and place applicable to Smart Work environments and verified that the five types of job autonomy have a statistically significant positive effect on Smart Workers' creative behavior. This study is meaningful in that it categorized job autonomy into five types applicable to Smart Work by adding temporal and spatial flexibility to the traditional job autonomy concept such as method, scheduling, and criteria autonomy and provided the basis for subdividing and evaluating the operation performance of Smart Work through multi-dimensional job autonomy verification.

최근 기후변화로 인해 강수량 및 강우패턴이 변화하고 있으며, 기록적인 가뭄이나 홍수와 같은 극한사상의 발생빈도가 점차 증가하고 있다. 국외의 경우 2000년부터 2021년까지 미국 서부 지역에서 극한 가뭄사상이 발생하였으며, 호주에서는 2017년부터 2019년까지 호주 남동부와 뉴사우스웨일스 지역에 극심한 가뭄이 나타났다. 국내의 경우 2000년대에 들어서 가뭄이 국지적으로 빈번하게 발생하고 있으며, 2022년부터 20023년까지 전라남도 지역에 극심한 가뭄이 발생하였다. CMIP6(Climate Model Intercomparison Project Phase 6)는 기후변화에 관한 정부간 협의체(Intergovernmental Panel on Climate Change, IPCC) 6차 평가보고서 (Sixth Assessment Report, AR6)에서 기후 모델 간의 비교와 평가를 위해 설립된 국제 협업 프로젝트로 기후변화를 예측하기 위해 다양한 기후 모델을 사용하여 미래의 기후 시나리오를 제시하였다. SSP (Shared Socioeconomic Pathways) 시나리오는 CMIP6에서 사용되는 미래 사회경제적 발전 경로를 나타내며, 기후변화의 다양한 미래 상황을 평가 및 기후영향을 분석할 수 있다. 국내 논 용수는 주로 저수지와 같은 수리시설물을 통해 공급되는 반면, 밭 용수의 경우 수리시설물로부터 용수를 공급받는 관개전은 일부에 불과하고 대부분의 밭의 경우 용수공급을 강우에 의존하여 가뭄에 더욱 취약한 실정이다. 본 연구에서는 CMIP5 기후모델 기반 RCP (Representative Concentration Pathways) 시나리오 및 CMIP6 기후모델 기반 SSP 시나리오를 적용하여 미래 기후 데이터를 비교하고자 한다. 또한, 미래 기후변화 시나리오를 토양수분모형을 적용하여 미래 밭가뭄을 전망하고자 한다.
