In the era of the fourth industrial revolution technology, the inclusion of personalized nutrition for healthcare (PNH), when establishing a healthcare platform to prevent chronic diseases such as obesity, diabetes, cerebrovascular and cardiovascular disease, pulmonary disease, and inflammatory diseases, enhances the national competitiveness of global healthcare markets. Furthermore, since the government experienced COVID-19 and the population dead cross in 2020, as well as numerous health problems due to an increasing super-aged Korean society, there is an urgent need to secure, develop, and utilize PNH-related technologies. Three conditions are essential for the development of PNH technologies. These include the establishment of causality between obesity genome (genotype) and prevalence (phenotype) in Koreans, validation of clinical intervention research, and securing PNH-utilization technology (i.e., algorithm development, artificial intelligence-based platform, direct-to-customer [DTC]-based PNH, etc.). Therefore, a national control tower is required to establish appropriate PNH infrastructure (basic and clinical research, cultivation of PNH-related experts, etc.). The post-corona era will be aggressive in sharing data knowledge and developing related technologies, and Korea needs to actively participate in the large-scale global healthcare markets. This review provides the importance of scientific evidence based on a huge dataset, which is the primary prerequisite for the DTC obesity gene-based PNH technologies to be competitive in the healthcare market. Furthermore, based on comparing domestic and internationally approved DTC obese genes and the current status of Korean obesity genome-based PNH research, we intend to provide a direction to PNH planners (individuals and industries) for establishing scientific PNH guidelines for the prevention of obesity.

Purpose - Vietnam has the fastest growing digital economy in Southeast Asia and is emerging as a critical overseas market for Korean banks in the post-COVID-19 era. Accordingly, many Korean banks entered the Vietnamese market to overcome the limitations of the saturated domestic financial market and create new revenue sources. This study examined the current status of digital finance in Vietnam and the cases of Korean banks that have succeeded in the Vietnamese market. Then, importance-performance analysis (IPA) was conducted on local customers, managers and staff members of Korean banks in Vietnam. Design/methodology - In this study, we analyzed the importance and satisfaction factors of mobile banking app usage in Vietnam through IPA. In particular, we identified the differences between the two groups by considering the viewpoint of customers who use mobile banking apps and that of managers and staff members who provide mobile banking services. Findings - The IPA results from the customer group and managers and staff members group were generally similar, but differences were observed in Ease of Use (Technology), Innovativeness (Organization), and Increase in Revenue (Economic). In the case of the customer group, Ease of Use (Technology) is located in the second quadrant, which shows low satisfaction compared to high importance. However, in the managers and staff members group, Ease of Use (Technology) is located in the first quadrant, which indicates high importance and high satisfaction. This difference in perception can cause complaints from local customers; thus, it is necessary to change the perception of the technological aspect for ease of use of mobile banking apps in consideration of the customer's position. In addition, it is necessary to allocate the resources invested in the Innovativeness (Organization) and Increase in Revenue (Economic) to Ease of Use (Technology). Originality/value - In this study, based on the HOTE framework, factors for using mobile banking apps were derived, and IPA was conducted targeting local customers (app user) and managers and staff members (app provider) of Korean banks in Vietnam. Through this, we presented the results of empirical analysis that can help Korean banks efficiently utilize limited resources and budgets.

This study was attempted to promote changes in traditional design education at a time when non-face-to-face education is necessary, such as digitalization, rapid social structure change, and post-COVID-19 situations, and to meet the demands of the times when user-centered design is more emphasized. Therefore, the goal of this study is to explore the process of developing mobile apps and operating education for deaf learners through design thinking-based interaction design education for design students. Specifically, the curriculum was designed by selecting a design thinking methodology suitable for major students to experience empathy and solutions to user problems. The subject that students majoring in this study want to sympathize with is deaf learners, and the subject of the curriculum is the development of educational support applications for deaf learners. Accordingly, a mobile app prototype that can support online learning for deaf learners was created based on the interaction design education plan designed based on design thinking. In addition, after collecting and analyzing the feedback of deaf learners to evaluate the prototype effectiveness, the final mobile app prototype was presented as an output. Through this process, interactive design education based on design thinking helped to strengthen the ability to empathize with and solve the needs of deaf learners to major students and improve the design learning experience. Based on these findings, if a methodology suitable for various user groups is selectively accepted for design education, the students in the major will have the ability to design by prioritizing the actual needs of users despite changes in the environment of the future design society.

Covid-19로 인해 비대면 수업이 지속되고 있다. 과거부터 e-러닝 수업은 있었지만 코로나로 인한 비대면 수업은 실시간 수업과 녹화수업이 결합되거나 대면과 비대면이 결합된 블랜디드(blended) 수업이라는 것이 차이점이다. 또한 전용 스튜디오가 아닌 곳에서 자가 촬영하거나 다양한 강의 플랫폼을 선택할 수 있다는 점이 특징이다. 비대면 수업의 이점은 시간과 공간을 초월하여 학습할 수 있고, 반복 시청, 학습속도를 조절할 수 있다. 녹화수업은 시간과 장소적 제약이 없지만, 실시간 수업은 시간적 제약은 있지만, 학습자와의 커뮤니케이션 효과가 높다는 장점이 있다. 비대면 수업이 대면수업이나 e-러닝과 비교하여 충분한 품질을 제공하는지를 평가하는 일은 포스트 코로나 이후에도 블렌디드 수업을 고려한다면 필요한 일이 될 것이다. 본 논문에서는 비대면 수업의 서비스 품질평가를 위해 Kano 품질속성 관점에서 학습자들이 원하는 필수속성을 도출하고 품질개선 방안을 제안하였다. 비대면 수업이 갖추어야 할 기능의 정도를 X축, 학습자의 만족도를 Y축으로 나타낸 후 23개의 품질속성을 6개로 분류하였다. 그리고 만족계수, 불만족 계수, 고객만족개선지수를 도출하였다. 학습자들의 50%가 비대면 수업에 만족했지만 선호도는 만족도 보다는 약간 높게 나타나 비대면 수업의 지속 가능성을 암시하고 있다. 고객만족개선 지수로 볼 때, 수업 품질을 개선했을 때 만족도 증가폭이 가장 큰 속성들은 학습자의 질문에 대한 교수의 신속한 답변, 교과내용을 반영한 충실한 강의 콘텐츠, 교수가 알기 쉽게 설명해 주는 것, 모바일 폰에서도 학습할 수 있는 고품질의 콘텐츠 개발, 출석체크의 공정성, 그리고 실시간 수업은 정시에 수업 시작 순이었다.
