Meanwhile, the research was conducted solely by the research team of Professor Tae-Jun Ha at Kwangwoon University and was funded by the Mid-career Researcher Project of the National Research Foundation of Korea, organized by the Ministry of Science and ICT. Moreover, the first author, Myeong-hyun Kim, achieved the remarkable feat of publishing a paper in a top-tier international academic journal within just three semesters of the master's program.
