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.

The purpose of this study is to investigate the history, space structures, blueprint, and techniques of the construction of Nam-hea city walls. Nam-hea city walls were relocated in 1439 from Whagumhun-Sansung(火金峴山城) to the present site, nearby Nam-hea Um.(南海邑) The city walls were rebuilt after they were demolished during Japanese invasion on Korea in 1592 and their reconstruction was also done in 1757. At present, the city walls only partially remained due to the urbanization of the areas around them. A plane form of the City wall is a square, and the circumference os approximately 1.3km. According to the literature, the circumference of the castle walls is 2,876尺, the height is 13尺, and the width is 13尺 4寸. Hang-Kyo(鄕校). SaGikDan(社稷壇), YoeDan(厲壇), SunSo(船所) which is a harbor, as well as government and public offices such as Kaek-Sa(客舍) and Dong-Hun(東軒) existed inside the castle walls. Inside the castle walls were one well, five springs, one ditch, and one pond, and in the castle walls, four castle gates, three curved castle walls, and 590 battlements existed. The main government offices inside castle walls were composed of Kaek-Sa, Dong-Hun, and Han-Chung(鄕廳) their arrangements were as follows. Kaek-Sa was situated toward North. Dong-Hun was situated in the center of the west castle walls. The main roads were constructed to connect the North and South castle gate, and subsidiary roads were constructed to connect the East and West castle gate. The measurement used in the blueprint for castle wall was Pobaek-scale(布帛尺:1尺=46.66cm), and one side of it was 700尺. South and North gate were constructed in the center of South and North castle wall, and curved castle walls was situated there. One bastion was in the west of curved castle walls and two bastions were in the east of curved castle walls. The east gate was located in the five eighths of in the east castle wall. Two bastions were situated in the north, on bastion in the south, one bastion in the south, and four bastions in the west castle wall. The castle walls were constructed in the following order: construction of castle field, construction of castle foundation, construction of castle wall, and cover the castle foundation. The techniques used in the construction of the castle walls include timber pile(friction pile), replacement method by excavation.

Generally the dynamic characteristics of stone wall structures depend on several factors such as contact, the type of interlocking bonding stones, and the filling materials. This paper describes a non-destructive technique for diagnosis of historic masonry stone structures using the measurement of natural frequency technique. For this purpose, the castle wall of Nag-An Folk Town located in Sunchon, Korea was selected as a model. The Nag-An Town Castle is one of the well maintained historical remains constructed in the Chosun Kingdom of Korea. The construction started in 1397 A.D and was finished in 1626 A.D. The non-mortar castle wall is 1470m long and the average height is 4m with a width of 3 4m. The exterior of the wall is bonded with 1 2 m rectangular rough-faced stone and the inside of the wall is filled with gravel. The traditional village still remains inside the Nag-An Town Castle, and they have a regional food festival every October. Transverse vibrations were measured at 8 points around the castle. The measured natural frequency of the first mode was 26Hz 41Hz, and the shear modulus of filling material was 2.142 x $10^3$ ~ 8.915 x $10^3$kgf/$cm^2$ . With these results, it may be assumed that the filling material is gravel or a sand-gravel mixture. It is expected that the information provided by this paper will be useful for addressing the maintenance problems of the old castle walls.

This study examined the construction method shown in literatures and materials discovered in rampart, barbican and guard platform for Cheongdo-Eupseong castle which was constructed immediately before Japanese Invasions of Korea (1592-98). According to the result of the examination, the construction method used in the coastal areas and inland areas of Gyeongsang province in the early Joseon period was applied to the rampart, barbican and guard platform in the east and north castle walls, which was constructed earlier than other parts of Cheongdo-Eupseong castle. However, from the western end of the northern castle wall, which was later constructed, to the western castle wall was rebuilt using a construction method different from the method applied to the parts that were constructed earlier after Japanese Invasions of Korea. Cheongdo-Eupseong castle was constructed on a flatland on a large scale and at a low height under unreasonable pressures to construct the castle in a short period of time for military defense as well as civil agitation in the imminent situation just before the outbreak of Japanese Invasions of Korea. In addition, various methods of constructing Eupseong castle utilized at that time were used together, and barbican and guard platform were built generally focusing on rapid completion and convenience, using other methods than the one mainly used at that time. This is the reason why there was a difference in the characteristics of the method and period of castle construction between Cheongdo-Eupseong castle and other Eupseong castles in the coastal areas and inland areas of Gyeongsang province.

본 연구에서는 풍납토성 동성벽 내부토양을 대상으로 색도색차계, XRD, 입도분석기 등을 이용하여 색도, 입도, 주요화학조성, 광물결정구조 등을 분석하였다. 성벽토양은 황갈색, 회황색의 모래 또는 실트질 모래(SW~SC)로 분류되고, 입도와 화학 광물학적 특성이 유사하며, 도로나 활주로 등의 성토재료로 적합한 특성임이 확인되었다. 색도, 입도, 화학조성, 강열감량의 4인자를 기준으로 비교분석한 결과, 풍납토성이 위치한 지역의 대조군 토양(PNS)은 성벽축조에 사용되지 않았던 것으로 판단한다. 모든 토양은 풍납토성이 위치한 지역과 지질학적으로 유사한 곳에서 채굴되었던 것으로 추정되지만, 성벽 축조 이전에 분포했던 구지표면의 토양과는 다른 특성을 나타내기 때문에, 유적 주변에 대량채굴이 가능했던 토양분포지가 존재할 것으로 추정된다. 향후 성벽 축조재료의 여러 특성들을 비교 분석하면, 성벽 내부토양의 산지, 축조방법, 보수방법 및 시기 등을 보다 종합적으로 이해할 수 있는 계기가 마련될 것으로 기대한다.

This study examined the background and change of building Yeongam eupseong and characteristics and construction method of its spatial structure. The results of this study can be summarized as follows. First, Yeongam eupseong was built for the same purpose of national border defense against the invasion of Japanese army as other Eupseongs were built and it was found first in the literature in the era of King Munjong of Joseon Dynasty with the scale of three gates and 4,369 cheok of castle wall. Such a scale was continued and in particular, according to flat structure, road network and gate position shown in the map, the form and road system of Yeongam eupseong before the 19th century were mostly identical with the current ones. Second, castle wall was built over foundation by using talcum after leveling the foundation soil and castle wall can be divided into outer wall, filling part and inner wall from the section. Outer wall was constructed by inserting and layering pebbles with big irregular stone, filling part was made with talcum and riprap and inner wall with soil in several layers by keeping gradient. This building method showed common features in inserting and layering pebbles for outer wall, use of protruded base and section form compared to Jeollado Eupseong.

The purpose of this study is that it is made clear the construction method of Japanese Castle Architecture in Korea as I study the construction method of Suncheon-Japanese Castle(順天倭城) in those days of Jeong-yu Japanese Invasion. Moreover, I intend to analyze the similarity and the difference between Suncheon-Japanese Castle and Korean Castle Architecture by a comparative study. The result of the study is showed that Suncheon-Japanese Castle seemed to be built with the object of a long time stay rather than it was of strategic importance for the national defense. In addition, it was different from other Japanese Castle in Korea because the watch tower(天守閣) of it stood in the middle of stronghold and the watch tower stronghold dividing the round of it while that of it stood the comer of stronghold. The face stone used in important part of watch tower, gate, and so on was mostly a trimed hexangular stone. On the other hand, the face abbuting on the Gulf of kwang-yang was made of naturally wild face stone. The stone cleared traces of Si-hyeol(矢穴) and domestic Castle in Japan was also made of this method after Im-Jin Japanese Invasion. According to the construction method, the wall of castle made use of the Netak(內托) method except the gate, the support stronghold and the watch. The early mountain castle in Korea have this construction method in common.

태봉 철원도성은 현실적 접근의 어려움으로 인해 조사와 연구에 제약이 있다. 따라서 현재 고고학계에서 이용되고 있는 고지형분석 방법론의 적용과 해석을 통해 도성의 구조와 내부 공간 구획의 여러 모습을 파악하였다. 태봉 철원도성은 외성의 북쪽 구릉지성 지형에서 시작하여 남서방향으로 흘러 내려온 다섯 줄기의 평탄한 구릉지형을 이용하여 축조하였다. 내·외성벽은 각 구릉의 능선 줄기를 중심으로, 궁성벽은 그러한 능선 줄기의 중심 구릉지에 축조하였다. 각 성벽에는 여러 방향의 성문과 문지 등이 확인되는데, 도성 내부 건물의 방향과 지형 형태에 맞추어 설치한 것으로 파악된다. 도성 내 궁성은 평면 사다리꼴의 형태이며, 그 내부에는 궁전지와 관련 건물지 그리고 배수관련 지형 등이 확인된다. 궁전의 동서방향으로는 추정 도로와 함께 성문의 위치도 확인되었다. 궁성과 내성의 공간은 각각의 구릉 지형에 맞추어 평탄대지를 조성하고 건물지를 배치하였다. 내성의 남쪽에는 연못지로 추정되는 저수지가 궁성에서 내성의 중심을 잇는 수직 선상에 자리하는 모습이다. 내성과 외성 사이에는 건물지 흔적은 잘 관찰되지 않지만 평탄한 대지 지형의 존재로 그 가능성을 파악할 수 있다. 태봉 철원도성의 전체적인 구조는 북동 방향으로 약 9도 치우쳐 평면 장방형의 형태를 띠고 있다. 구릉성 지형의 형태를 따라 설계하였던 것으로 보이며, 남서벽의 꺽임 현상 또한 습지성 지형을 회피를 의도한 것으로 파악된다. 아직 도성 내부의 건물지 기능과 성격이 불명확하여 이를 바탕으로 한 공간 활용의 모습도 분명치 않다. 하지만 내성은 궁전과 함께 관아 건물지로서의 이용 공간으로서, 외성과 내성 사이 공간은 일반민의 생활 공간으로서 구분되었을 것으로 추정된다. 방리제로서의 구획 흔적도 구릉성 지형의 존재로 인해 그 가능성은 낮아 보이지만, 일부 지형은 평탄한 지대가 넓게 확인되고 있어 정연한 공간 구획의 모습을 배제할 수는 없다. 각 성벽의 축조 선후 시기나 방식 등도 아직 명확치 않지만, 적어도 지형을 이용한 도성의 축조와 내부 공간 구조의 활용을 이해할 수 있다.

Ancient masonry towers are regarded as among the most important historical heritage structures of the world. These slender structures typically have orthogonal and circular geometry in plane. These structural forms are commonly installed with adjacent structures. Because of their geometrical shapes and structural constraints, ancient masonry towers are more vulnerable to earthquake damage. The main goal of the paper is to investigate the seismic behavior of Erzurum Clock Tower under earthquake loading and to determine the contribution of the castle walls to the seismic performance of the tower. In this study, four three-dimensional finite element models of the Erzurum Clock Tower were developed and the seismic responses of the models were investigated. Time history analyses were performed using the earthquakes that took place in Turkey in 1983 near Erzurum and in 1992 near Erzincan. In the first model, the clock tower was modeled without the adjacent walls; in the second model, the clock tower was modeled with a castle wall on the south side; in the third model, the clock tower was modeled with a castle wall on the north side; and in the last model, the clock tower was modeled with two castle walls on both the north and south sides. Results of the analyses show that the adjacent walls do not allow lateral movements and the horizontal displacements decreases. It is concluded that the adjacent structures should be taken into consideration when modeling seismic performance in order to get accurate and realistic results.

Vegetation structure of Seokseong fortress in Buyeo-Gun was investigated to suggest a desirable management proposal. Communities by phytosociological method were classified into Pinus rigida-Pinus densiflora community and Quercus variabilis community. The importance value of Pinus rigida, Pinus densiflora, Quercus variabilis, Pinus thunbergii, and Quercus acutissima were 127.06, 70.29, 69.63, 12.39 and 8.57. According to breast diameter analysis results, it is expected that the importance value of Pinus rigida, Pinus densiflora, and Quercus variabilis will be continuously increased. It should be prepared that vegetation management plan over the castle wall should be considered before the repair or restoration of castle wall. Vegetation management around castle wall should be carried out according to the mid or long-term plan and it would be needed to consider the gradual changes from planted Pinus rigida to the historical vegetation of Pinus densiflora.
