Compared to Early Chosun Dynasty, the spatial structure of most local Eupseongs of Korea had a standardized change with the expansion and spread of the Rye-hak(禮學:a study of confucius Rite). Meanwhile in the process of rebuilding Eupseongs there was a tendency of relocation of the local government offices(官衙) and its attached facilities in terms of functions and use. Although it was PyeongSanseong Miryang Eupseong had an unreasonable spatial structure locating Gaeksa(客舍; accommodation house for visitors) in the middle of the local government office complex, and Dongheon(東軒;main office building) in the east of it before the Japanese Invasion of Korea in 1592. However with the reorganization of spatial Structure of local Eupseongs after the Japanese invasion Gaeksa was moved to the foot of Adongsan where commanded a fine view of river. Dongheon was moved to the center of Eupseong for the effective management of its auxiliary organizations. It was because road system and administrative efficiency had a serious effect on deciding the location of the local government office and its attached facilities. After the Japanese invasion Hyangchoeng(鄕廳), having been out of Eupseong, also was moved to the independent location within Eupseong separate from Dongheon and Gaeksa. It seemed to take into account the autonomy of Hyangchoeng. Dongheon, Gaeksa, and Hyangchoeng which are the crucial facilities of Milyang Eupseong were arranged at each angular point of big triangle. In order to enhance the administative efficiency, the attached administrative facilities were arranged surrounding Dongheon and Hyangchoeng. The spatial structure of Milyang Eupseong in the late Choseon dynasty was of great difference from that of uniformly organized system of early Choseon Period. It was because the development of administrative function, the pursuit of efficiency, and commercial progress had a great impact on the change of urban space.

울산광역시 울주군 서생면 서생리 진하해수욕장 서편 야산 구릉에 위치한 서생포왜성(西生浦倭城)은 임진왜란 시기에 가토 기요마사(加藤淸正)에 의해 축성되었다. 서생포왜성은 남․동해안 각지에 현존하는 30여개의 왜성 가운데 보존상태가 가장 뛰어나 왜성 연구의 최적지가 되고 있으며 임란 중 사명대사가 가토 기요마사와 4차례에 걸친 평화교섭을 진행하여 많은 외교적 성과를 거둔 역사적 장소이기도 하다. 또한 임진왜란 직후부터 1895년까지 약 300년 동안 조선 수군(水軍)의 동첨절제사영(同僉節制使營)으로 사용되었기에 근세기 한일간 축성법의 비교연구뿐만 아니라 성곽이용방식에 대한 상호 고찰도 가능하다. 이에 본 연구는 지금까지 주로 일본인 학자들에 의해 연구가 진행되었던 서생포왜성에 대한 조사연구를 진행함으로써 일차적으로는 왜성의 성곽구조와 체성 축조기법상의 특성을 밝히고 이차적으로 한국성곽과의 비교연구를 위한 기초 자료를 제공하고자 하였다. 연구방법으로는 일차적으로 문헌조사를 실시하고 이를 토대로 현장실측조사를 진행하였다. 그 결과 입지 및 평면형태, 성곽 내부의 공간구조, 虎口와 해자 등의 방어시설물, 체성 및 隅角部축조수법, 성벽의 기울기 등 서생포왜성의 제반 특성을 이해할 수 있게 되었다.

Periodically, the Japanese Castle was created in the domestic of Japan and then 2 invasions into Chosun was started. The Japanese Castle in the domestic of Japan was repaired several times by the building boom of castle before & after 2 invasions and so the initially-built type of castles was changed. Accordingly, there are much difficulties to understand the original shape of Japanese Castle. Through the Japanese Castle within Korea called as the fossil of Japanese Castle, I would like to examine & consider its building period and characteristics. The terminology called as [Two Side Stone's Wall] is that of castle which is not acknowledged in the Japanese Academic Circles. However, it means the two-fold wall of Japanese Castle which was widely applied to the fortification way in the Age of Japan Edo. The terminology of [Sori] says the stonework curve in the corner of Japanese Castle which is indicated best in the Japanese Castle. It calls the curve as like the fan frame. [Curb Stone's Wall] says the type of castle wall constructed with over 1 face in wall body of Japanese Castle. (1) About classifying the construction period of Japanese Castle, the curb stone's wall and the castle having no two side stone's wall must consider the building period as that of Japanese Invasion of Korea in 1592. If there was [Sori], the two-side stone's wall was used and the place which supported the documentary data, in particular, the place having the record of contraction is considered to be confirmed as the castle constructed in the period of Japanese Invasion of Korea in 1597. (2) The two-side-type stone's wall shown in the Modern Japanese Stone Castle is difficultly considered to be generated from the Japanese Castle at the period of Japanese Invasion of Korea in 1592 and in 1597. (3) The beautiful [Sori] shown in the Modern Japanese Stone Castle was started from the Japanese Castle of Korea at the period of Japanese Invasion of Korea in 1597. It is difficultly considered which its indication was firstly generated by the Chaesung-Folded Segment Structure.
