This paper aims at the examination on the fallacy of the name of ‘Dadaepo-gaeksa’. The results are as follow: The so called ‘Dadaepo-gaeksa’ was one of the official buildings of Dadaejin, the naval forces in the late period of J osun dynasty. The building was moved to Molundae near the original site in 1970. And two years later, it was designated as a cultural asset. However it’s real name is ‘Dadaejin-dongheon’, because Dadae-jin gaeksa was demolished about the time of the foundation of Dadaepo-elementary school. Otherwise, Dadae-jin donheon was used as a school building from 1904 to 1970. Futhermore, the architectural style of the existing building is different from the general gaeksa’s in the period of J osun dynasty. Therefore, the name of Dadaepo-gaeksa needs to change into Dadaejin-gaeksa and to restore as its original style.

The study on the government office building in Chungcheong Suyeong(忠淸水營) is very rare. How were the Gaeksa(客舍) and Dongheon(東軒) which are representative government office buildings in Suyeong, maintained and what was the aspect of it, while passing through the upheaval period of the end of Joseon(朝鮮)? And where was the original place and was there any change in use? It is so regrettable that these subjects were not figured out yet. So I thought it is very important task to figure out its actual aspect by investigating the maintain state of the Gaeksa and Dongheon and the change of their places. So this study examined the related historical records and, based on it, analyzed 「Ocheon GoonJi(鰲川郡誌)」in various view points. Through this analysis, this study could figured out the maintain aspect of the gaeksa and dongheon and the change of their places, and be able to deduce the other change of the government office building. This study could assume the places of each government office buildings by comparing this investigated result and the analyzed result of the original cadastral map in various view points. As the result of the study done by this method, this study confirmed the maintain state of the Gaeksa and Dongheon in Chungcheong Suyeong while passing through the upheaval period of the end of Joseon. And this study figured out the places of the Gaeksa and Dongheon, and be able to confirm their places by the lot number on the original cadastral map. Along with this, this study could estimate Jo(趙) family's confliction with the residents at that time by verifying the lot numbers of the Sapaeji(賜牌地) which this family received from the government. And among the names of the government office buildings, for the Jangkyocheong(將校廳) which is in dispute because of the name, this study figured out that the author of 「Ocheon GoonJi」made a mistake in writing Dongheon.

The aim of this study is to investigate the conversion of Dongnaebu Gaeksa block to public market during Japan’s Colonial Period. The block of Gaeksa was converted into the elementary school for the first time and afterwards occupied by the public market. Dongnae Traditional Market(五日場) had kept up since late 18th century. Dongnae public market was transferred to the site of Dongnaebu Gaeksa in 1937. Especially Dongnae public market(東萊公設市場) in the construction cost of establishment was supplied on loan. A number of traditional markets were reformed into the public markets in the 1930s. and the public market was installed more by the organization of colonial period. Dongnae public market was one of those markets, too. Eventually the establishment of public market meant that the block of Gaeksa had disappeared completely.

The purpose of this study is to analyze the process of lots-subdivision within the block of Gaeksa at Dongnae-bu under the rule of Japanese Imperialism. Gaeksa of the old government office was the sanctuary that symbolized the sovereignty. Therefore it was naturally a main object of demolition and then the site was converted to other purpose. And Gaeksa was not only converted into the elementary school and the public market but the historic site also processed to break down for opening the road through Japanese Occupation of Korea. The main reasons of lots-subdivision were the transfer from state property to private ownership and the urban development project. Needless to say, the particular major reason was derived from the intention of Japanese Imperialism to destroy the traditional urban. As a result, Gaeksa can not be recognized the traces of today and contributes to the demolition of the remaining ancient building. Finally the deformed urban structure was left over from destroyed building.
