Overcoming the extremely rigid, thus seemingly unchanging modern academic discipline system and the need for convergence research to do so are leading to even stronger demands today. Against this backdrop, this work mainly aims to open academic public spheres, in which various discussions can be derived from presenting 'convergence research as a synthesis'. This is in fact achieved by means not merely of introducing 'A Comprehensive Investigation into Nujeongs and Their Pyeonaeks in the Era of Joseon Dynasty', which was selected in 2022 as a convergence study granted and supported by National Research Foundation of Korea, but of applying its core methodology to Jiseonjeong (止善亭) and Wolsongjeong (月松亭), Cheongju's representative Nujeongs. The work adopts the convergence research method crossing linguistics, philosophy, cultural studies, architecture, landscape architecture, and cultural heritage studies, based on which case studies on the two Nujeongs are conducted. In the case studies, it comprehensively judges and analyzes the following: an approach of linguistics to the variants of some Pyeonaeks in Jiseonjeong, that of literature and philosophy to the view of Jiseon (止善) by Oh Myeong-Lip (吳名立), the builder of Jiseonjeong, that of cultural studies to the intertextual value of a Pyeonaek in Jiseonjeong, that of architecture to the relationship between the main functions of the two Nujeongs and their architecture, that of landscape architecture to their location and landscape characteristics, and that of cultural heritage studies to the values of all major elements such as location, landscape, architecture, and Pyeonaeks. In the final analysis, it mentions some limitations and possibilities among which ‘from physical bonding to chemical bonding’ and ‘adding today's social (re)interpretation to past cultural heritage and transforming it into a future cultural asset shared by every citizen’ are most notable for following researchers.
