This study strives to seek the background in Ho-Seo Bank(HQ)'s foundation and its urban meaning. First, the thesis intends to understand the autonomous characteristics of Ho-Seo Bank which had been supported by Korean capitalists(landowners and merchants), keeping their pure capitals acquired by regular traditional marketplaces and farming works around Yesan. Second, through quantification data, it deals with reasons that the Ho-Seo Bank have been situated on a triangular corner that meets three roads toward a main thoroughfare toward Gongju to Hongseong, a railroad station, and a downtown area(Honmachi(本町通)) each. Third, it discusses the subsequent changes of Yesan's urban landscape that resulted from the Ho-Seo Bank's foundation(1913). In other words, thanks to a newly founded Ho-Seo Bank's headquarter(1922) and partly opening of a railway(Gyeongnam, 1922), Yesan became more advanced constructing both a political venue for a military police, a county office, et cetera, and then an educational place for schools. In conclusion, such urban phenomena shows there would be a dual combination between Korean people(aboriginal landowners and intellectuals) in autonomous efforts and Japanese officials in heteronomous controls. This thesis further contends that Ho-Seo Bank architecture itself reflects their status in the locality, who envisioned a 'cultural equality,' competing with Japanese aggressors, and its firm and massive form shows a new building type of bank architecture, literally representing the safeness and firmness, so differentiated from other buildings with the 'Secession' style in colonial areas under the control of the world powers.

본 연구에서는 라우릴 알코올에 에틸렌 옥사이드 3 몰과 프로필렌 옥사이드 1 몰을 부가한 후 설페이션을 공정을 거쳐서 ASCO^Ⓡ SLES-430을 제조하였으며, 합성한 계면활성제의 구조를 FT-IR, ¹H-NMR 및 ¹³C-NMR 분석을 통하여 확인하였다. 합성한 ASCO^Ⓡ SLES-430의 임게 마이셀 농도, 정적 표면장력, 유화력, 접촉각 등의 계면 물성과 경구 독성 및 피부 자극성 등의 안정성 지표 등을 측정하였으며, SLES 계면활성제 내에 에틸렌 옥사이드가 각각 2 몰 및 3 몰 부가된 ASCO^Ⓡ SLES-226 및 ASCO^Ⓡ SLES-328 계면활성제들과 비교하였다. 특히, ASCO^Ⓡ SLES-430의 기포 생성력과 기포 안정성을 평가하여 기존 세제 제품에서 널리 사용되고 있는 ASCO^Ⓡ SLES-226과 ASCO^Ⓡ SLES-328과 비교함으로써 ASCO^Ⓡ SLES-430의 소형 빌트인 세탁기용 세제 적용 가능성을 검토하였다.
