This research focused on the regional and temporal attributes of tuff architecture in Mokpo, spanning the Japanese colonial period and the post-liberation era. It aimed to uncover the distinct regional and temporal features of tuff architecture by integrating concepts from vernacular architecture and regionalism, framed through a lens of critical regionalism. The study traced the historical progression of tuff architecture in Mokpo within this context. A significant part of the research was an in-depth analysis of four constructions by Son Yang-dong, a renowned technician in post-liberation Mokpo, to closely examine the contemporary relevance and regional significance of his work. Tuff, as an indigenous material, distinctly articulates the local architectural character. In line with regional properties of tuff, the material has adeptly responded to contemporary construction needs. This has laid a foundation for the development of innovative building designs and techniques. Tuff architecture is particularly noted for its exhibition of raw material textures, offering a unique aesthetic that diverges from classical Western architectural styles. Importantly, through the examination of Son Yang-dong's contributions, the study highlights the role of Korean builders in an industry dominated by Japanese influences during the colonial period, underscoring a strong regional identity. As a representation of Mokpo, tuff architecture not only upholds and protects regional identity within the broader scope of Western modernization and Japanese impacts but also plays a role in its progressive enhancement.

본 연구는 동아시아 핵심 국가의 지역주의와 패권 경쟁의 전환기 역사 관계에 대한 이해를 제공하고자 한다. 세계화는 1970년대 이후 동아시아에서 성장하는 국가에게 새로운 경제의 기회를 제공했다. 동아시아에서 새로운 지역주의의 출현은 1980년대 말부터 핵심 국가 간의 헤게모니 경쟁과 함께 증가했다. 미국과 호주가 시작한 APEC의 경제적 자유주의 전략은 동아시아 개발도상국의 개발 전략을 지원하는 EAEC와 대조된다. 아시아 금융 위기 이후 구조적 시장 지배력과 독립적인 정치적 주권을 바탕으로 한 중국의 출현은 아시아 지역주의를 재편했다. 그리고 APT는 중국과 일본 간의 경쟁을 촉진했다. 이 연구는 동아시아의 지역 조직이 강국의 지역 헤게모니를 강화하고 약한 국가의 주권을 유지하는 도구라고 주장한다.

The core idea of the critical regionalism could be summarized as a self-conscious synthesis between universal civilization and world culture. After World War Ⅱ, it has been applied to architecture for overcoming the problem of Industrial Capitalism and uniformity of 20th century Modern Architecture. Naturally, religious architecture cannot also be an exception in this cultural trend, thus we can also apply the critical regionalism to the Korean Catholic Church Architecture with the basic premise that the Traditional Western and Modern Style Church Architecture should be regarded as universal civilization, and the Traditional Korean Architecture and endemicity as one of world culture. In the context, this article attempts to analyze the regionality of Korean Modern Catholic Church Architecture constructed between the 19th century and 1980's, and how it has been differently transformed with the view of the critical regionalism. Its analysis will be carried out within three types; transformation of the Traditional Korean Architecture and the influence of Japanese Modern Architecture, representation of the Traditional Korean Architecture, and abstraction of the Traditional Korean Architecture with each advantages and disadvantages.

This writing is to understand some trends and its meaning of Regionalism Architecture in Jeju Island since 1950's.This thesis began with an interestin the identity crisis implicitin the simultaneous striving formodernism and the so-called regionalvalues in Jeju Island.Regionalism is a response in architecturalterms to re-establish continuity in a given place between pastand presentforms,and also a uniqueresultrelated to particularplaces,culturesand climatesin region.Thisisone wayoflookingattheissuesofregionalidentity. Thestudy began by observing thegeneralcharacteristicsofcontemporary ideason Regionalism inJejuarchitecture.Thismeansthattracingthehistoryofdevelopmentof Regionalism architecture in research area is notthe focus ofthis thesis.The thesis demonstratesthatRegionalism architecturesin Jeju showssometrendsrelated to the local cultural elements (or ideas) such like traditionalarchitectural forms,natural environment,local construction-materials,etc.In summation,in the perspective of Regionalism architecture,mostofbuildingsin Jeju bring outthem only asvernacular architectureasitwasonceproduced,by thesimplecombination andimitation without anycreativeinteractionoftheregionalculture.
