In the present age, the social and economic structures are rapidly shifting to a digital base. In the cosmetics and beauty field, “contactless industry” which is grafted into the digital technology has been on the issues. In the field of education, educational standard is increasing through digital transformation using “Edu-Tech”. This study is to explore a new paradigm of beauty education to respond to the digital transformation era. Moreover, it aims to find academic basis to train digital savvy manpower in the field of cosmetics and beauty. The research methods are as follows: trends in domestic and foreign cosmetics and beauty industries were analyzed by referring to academic and degree papers, academic presentation documents, trends and research reports, and websites with the keywords of the 4th Industrial Revolution, Digital Transformation, Edu-Tech, beauty education, and cosmetics and beauty industry trends. This study results can be summarized in five points as follows. Firstly, government announced a plan to build a related infrastructure to increase productivity dramatically with the “Digital New Deal”. Secondly, “Edu-Tech” industry can lead the digital transformation to provide customized education. Thirdly, the government selects and promotes four key projects: the development of sustainable K-beauty innovative technology, enhancement of corporate activities through regulatory improvement, support for strategic overseas expansion, and creation of the K-beauty industry ecosystem. Fourthly, major issues in the global cosmetics market include differentiation of clean beauty, realization of substantiality, marketing with the new technologies such as AI, AR, VR, and Metabus, and expansion of the customized cosmetics market. Finally, domestic and foreign companies leading those industries also take the head of digital transformation in manufacturing, distribution, and marketing. Based on the research results above, three conclusions are presented. First of all, it is the development of a curriculum for the digital indigenous generation that has to actively respond to changes in the future society. Nextly, innovation is also required in the development of digital education programs and textbooks. Lastly, it is an effort for instructors to change the perception of digital transformation and to strengthen digital capabilities. Digital transformation should be accompanied by a selfdirected educational system centered on learners rather than the existing system centered on instructors. The reason is that it is necessary to respond to the continuous reduction in the number of students, the crisis of higher education due to COVID-19, and the rapidly changing both internal and external environments.

This study mainly aims to analyze how the appearance management behaviors from active seniors affect quality of life by mediating selfesteem. A survey for the research was conducted on 396 men and women in their 50s and 60s living in Seoul metropolitan area, and the results of data analysis using SPSS WIN 23.0 program are as follows. The factors of appearance management behavior were extracted into three factors: fashion, beauty, and body type management. For the quality of life, it was extracted into physical health, mental health, and social health. As a result of conducting multiple regression analysis to clarify the effect of appearance management behavior and self-esteem on the quality of life, body type management and self-esteem had a statistically significant effect on the quality of life: physical, mental, and social health (p<.001). In brief, self-esteem played a complete mediating role in the relationship among fashion, beauty management, and quality of life with physical, mental, and social health. At the same time, it became a complete medium between body type management and quality of life with social health. In addition, self-esteem plays a partial mediating role in the relationship between body type management and quality of life with physical and mental health. Through the results of this study, it was confirmed that appearance management behavior is a significant factor in increasing self-esteem of active seniors. In particular, appearance management behavior is an important factor for them to prepare their own healthy old ages physically, mentally, and socially. Thus, active seniors’ appearance management behavior should be considered in terms of marketing and service or developing customized products for them in the beauty and cosmetic industry.

Customized cosmetics sales will be legalized from March 2020. People can make and purchase their own cosmetics at the store, and a new qualification system called customized cosmetics preparation manager will be established. This qualification allows people to do manufacturing and purchasing customized cosmetics. The purpose of this study is to examine these both customized cosmetics and the system of preparation manager who dispense the customized cosmetics. Especially, an online survey of adult men and women from the all parts of the South Korea was conducted to provide an academic foundation. In addition, this academic foundation is designed to quickly recognize and cope with the changes in the cosmetics industry environment and in the needs of consumers. Collected data were used for the frequency analysis and technical statistics using SPSS21.0. To sum up, most respondents do not have any experience using customized cosmetics, and they tend to have low awareness concerning new system of customized cosmetics. Nevertheless, there are many positive respondents about the customized cosmetics because they believe that those are suitable cosmetics based on consumers’ skin conditions. They think that new system which is related with the customized cosmetics needs to be established, too. They also responded that a verification system for the sellers of customized cosmetics is essential and that the training of experts with the national qualification is necessary. Meanwhile, most respondents think that makeup is a tool for transformation when asked about individual makeup behaviors. Furthermore, most of them answered that natural makeup which is suited to them is much better than copying other people’s makeup unconditionally. People can predict that the era of customized cosmetics will gradually come with these research findings. Through this new cosmetics system and that of preparation manager, domestic cosmetics markets not only can create new jobs but also can take another opportunity to make a new leap forward.

Purpose: The purpose of this study was to evaluate the effect of denture cleansers on the flexural bond strength of heat curing denture base resin and reliners. Methods: The denture base resin was bonded to the reliners(vertex self curing, kooliner, rebase Ⅱ) to make the specimen. The specimens were immersed in denture cleansers(Polident, Cleadent) and evaluated after 1week, 3week, 5weeks. After denture reliners were injected, flexural bond strength was measured. Results: The bond strength of denture base resin and vertex self curing resin as reliner was significantly decreased at 5 weeks in cleadent and polident(p<0.05). The bond strength of kooliner and rebase Ⅱ was significantly decreased at 5 weeks in denture cleaners(p<0.05). Kooliner was significantly decreased at 3 and 5 weeks in polident and rebase Ⅱwas significantly decreased at 3 and 5 weeks in all denture cleansers(p<0.05). Conclusion : The flexural strength between the denture base resin and the reliners decreased significantly as the treatment time increased.

자동차 내 운전자나 동승자에게 여러 정보와 오락적인 기능 모두를 제공해 주는 IVI(In-Vehicle Infotainment)가 자율주행 자동차의 다양한 연구 영역 가운데 특별히 주목받고 있다. 더불어, 현재 자동차 업계에서는 IVI의 위치 가 달라지고 있다는 점이 특징적이다. 본 연구의 목적은 자율주행 자동차 내 IVI의 위치 변화에 따른 탑승자 경험을 분석하고 적절한 자동차 HMI(Human Machine Interface), UX(User Experience), 디자인의 활용 방 향에 대한 토대를 마련하는 데 있다. 이에 따라 개방 코딩을 통해 자율주행 자동차 내 IVI를 통한 탑승자 경험을 분석하였고, 컨셉카를 조사하여 IVI 위치별로 매핑하였다. 이후 결과물을 간접적으로 검증하고자 전문가 인터뷰 를 진행하였다. 연구 결과, IVI에 대한 탑승자 경험의 주요 요인은 ‘공간적’, ‘시간적’, ‘품질적’, ‘문화적’ 총 4가지 요인으로 도출되었고, 컨셉카를 기반 으로 조사한 결과 각 IVI의 위치는 ‘운전석’, ‘조수석’, ‘후석’, ‘측면’, ‘천 장’, ‘바닥’과 같이 총 6가지로 구분되었다. 도출된 탑승자 경험과 위치를 매핑한 결과를 전문가 인터뷰와 함께 종합하였을 때, 각 IVI 위치에 따라 어떠한 탑승자 경험을 제공하는 것이 적합한지 확인할 수 있었다. Among IVI(In-Vehicle Infotainment), which provides both informational and entertainment functions to the driver and passengers in the car, is of particular interest. Furthermore, the current position of IVI in the automotive industry is characterized by its evolution. The purpose of this study is to analyze the occupant experience of IVI in autonomous vehicles and lay the groundwork for the appropriate use of autonomous vehicle HMI(Human Machine Interface), UX(User Experience), and design. Accordingly, we analyzed the occupant experience of IVI in autonomous vehicles through open coding, and concept cars were examined and mapped by IVI location. Expert interviews were then conducted to indirectly validate the findings. As a result of the study, the main factors of occupant experience with IVIs were identified as 'spatial', 'temporal', 'quality', and 'cultural', and based on the concept car, each IVI was categorized into six locations: 'driver's seat', 'passenger seat', 'back seats', 'door trim', 'roof', and 'floor'. When the results of mapping the derived passenger experience and location were combined with expert interviews, it was possible to confirm what kind of passenger experience it is appropriate to provide for each IVI location.
