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 physical characteristics of the major varieties of perilla were analyzed to use as basic data for the design of a high-quality, high-efficiency perilla cleaner and stone separator. Because the size, thousand-grain weight, angle of repose, angle of friction, bulk density and terminal velocity of perilla have significant differences according to the perilla variety, the different of characteristics by variety should be considered for performance improvement of a perilla cleaner and stone separator. Therefore the cleaner and stone separator using a sieve could be improved by the application of a detachable sieve or by using equipment such as a 2 - 3 stage sieve and regulating the slope. Moreover, because differences in the terminal velocity occur due to the differences in the size and thousand-grain weight according to the perilla variety, a blower with an adjustable fan speed was considered for the design of the improved cleaner. Additionally, it was shown that the length of perilla has the greatest correlation based on a comparison of the coefficients of the other characteristics. Accordingly, the length of perilla could be used as a major factor for the fine adjustment and parts replacement of the device. These results can be used as basic data for a high-quality, high-efficiency perilla cleaner and stone separator. In the future, the development of the machine and follow-up studies based on the basic data are needed to determine the optimized operating conditions and mechanism of action.

The wooden pagoda was first appeared in about late 4th century in Korea. And between the late 6th century and the eary 7th centry, the multistoried wooden pagoda was replaced with the stone pagodas, in order to improve their stability and durability. In Three-kingdom and Unificated-Silla period, there are two types of stone stupas in Korea. The one is Paekche(百濟)style, and the other is Silla(新羅) style stone pagoda. These two styles are basically different in each part like podium, roof stone, body stone, structure and the others. Two types of stupas are distributed in two regions which devided into the East(Silla territory) and West(Paekche territory) in the Korean peninsular. The origin of the Korean stone pagoda can be traced to the Paekche dynasty and Silla dynasty. The former were the result of the careful study of their skillful wooden pagodas, where the latter were actualy originated from copying their sundried brick pagodas with stone. Two important pagodas of the primitive stage are the stone pagoda of Miruksa(彌勒寺) temple in Iksan and Bunhwangsa(芬皇寺) temple in Kyungju. These two pagodas are compared with each other in the style of their construction. Silla style have sharp straight lines and short distance between roof stone and eaves. They give us strong as well as intelletural feeling. Howerever, Paekche style has curved lines and dull angles of cutting area of stone, they give us soft feeling.

Recent earthquakes in Korea caused some damages to stone pagodas and thereby awakened the importance of earthquake preparedness. Korean stone pagodas which have been built with very creative style of material use and construction method are worthy of world heritage. Each stone pagoda consists of three parts: top; body; and base. However each tower is uniquely defined by its own features, which makes it more difficult to generalize the seismic assessment method for stone pagodas. This study has focused on qualitative preliminary evaluation of stone pagodas that enables us to compare the relative seismic performance across major aspects among many various Korean pagodas. Specifically an analytical model for multi-block stone pagodas is to be proposed upon the investigation of structural characteristics of stone pagoda and their dynamic behavior. A strategy for seismic evaluation of heritage stone pagodas is to be established and major evaluation factors appropriate for the qualitative evaluation are identified. The evaluation factors for overall seismic resisting behavior of stone pagodas are selected based on the dynamic motions of a rigid block and its limit state. Numerical simulation analysis using discrete element method is performed to analyze the sensitivity of each factor to earthquake and discuss some effects on seismic performance.

적석목곽묘는 목곽 외부에 석재를 쌓거나 채운 다음 목개 위에 일정한 두께로 적석하고 점토로 밀봉한 구조이다. 경주 중심부라는 한정된 공간 속에 거의 모든 지배자가 지속적으로 한 묘제를 사용하였다는 점, 타 지역에서 확인되는 적석 형태와 전혀 다르다는 점 등에서 경주식 적석목곽묘로 정의하고자 한다. 적석목곽묘는 경주 중심부에서 5C 전반대부터 축조되기 시작한다. 평면형태, 목곽, 이중곽, 석재충전, 석단, 순장 등은 이전시기의 목곽묘에서 계보를 잇고 있다. 이외에 석축과 목주, 적석, 성토분구는 적석목곽묘의 출현과 함께 새롭게 나타나는 요소이다. 특히 석축과 목주는 황남대총을 비롯한 지상식 초대형분에서만 확인된다. 석축과 목주, 적석은 모두 성토 분구 축조과정 속에서 하나의 공정을 이루고 있다. 석축은 지상에 설치된 목곽의 외벽을 견고하게 유지시켜 주면서 성토 분구의 하중을 분산 수용한다. 목주는 석축의 붕괴를 방지하기 위한 보조장치로서 횡가목, 버팀목 등과 함께 사용되었다. 적석은 일정 크기의 석재를 갖고 일정한 두께로 목개 상부에 덮었다. 그리고 그 위에 점토로 밀봉한 다음 분구를 성토하였다. 적석은 경주지역의 입지적 특성이 반영된 것으로 파악된다. 경주 중심부의 적석목곽묘는 하천부지가 넓고 평탄한 형산강 동안을 따라 분포한다. 기반층은 대부분 모래와 냇돌로 구성되어 있다. 따라서 성토분구는 모래성분을 많이 함유하고 있다. 목개를 횡가한 다음 바로 성토할 경우 유수에 의한 붕괴 가능성 또한 크다. 고분의 외형을 유지하면서 내부구조물의 파괴를 방지하기 위하여 적석과 점토밀봉이 이루어진 것으로 판단된다. 상부의 봉토가 유실되더라도 하부의 적석은 형태를 어느 정도 유지할 것이기 때문이다. 성토분구는 국가 혹은 단위정치체가 성장단계에 진입하면서 나타나는 하나의 특징이다. 국가 출현단계 이후 성장단계에 진입하면서 사회구조에 변화가 나타나고 이와 맞물려 새롭게 출현한 지배등급에서 전대의 목곽묘와는 다른 적석목곽묘를 축조하기 시작한 것으로 판단된다. 이 과정에서 분구를 함께 성토한 것으로 파악되며, 지배등급의 성격에 따라 규모와 구조에서 차이를 보인다. 평면형태, 곽과 석단, 순장자의 수, 유물의 양과 질 등은 지배등급의 사회적 지위를 반영하고 있다. 따라서 적석목곽묘는 신라가 성장단계에 접어든 시점에 전대의 묘제로부터 분화 발전된 양상을 보이면서 나타난것으로 생각된다.

Stone has been one of the most intensely studied materials in conservation. Understanding the deterioration of stone needs various knowledge in different mineralogical and physical characteristics and its weathering response under different climate and environment. The alteration and weathering of stone is affected by natural or artificial elements whether they are physical, chemical or biological damaging factors. It can be said that the bio deterioration of stone is coupled with every environmental factors, which induce decomposition of stone structure, either directly or indirectly as a form of catalysis. Many elements contribute to the deterioration of stone monuments and other objects of cultural value such as pagoda, stature of Buddha, etc. This report concentrates on the action of biodeteriorative factorsincluding bacteria, algae and higher plants. Preventive and remedial methods and a selection of chemical treatments are also described.

The stone lantern of the Damyang Gaeseonsaji temple site is a cultural heritage built during the Unified Silla period (AD 868). The reason for its value as a cultural property is due to wittern the background and the period created on inscription of the lamp stone engraved by letters. The stone lantern consists of two types of lithic tuffs for the 23 original properties, the replaced stones in 1991, and the biotite granite for its ground stones replaced in 2005. The lithic tuffs selected as the replacement parts in 1991 and 2017 have been examined and got to properties of hardly exposure moisture as well as very similar geochemical characteristics. There were various types of physical deterioration of the stone properties and structural cracks; in particular, on the northern side of the stylobates. Chemical and biological deterioration can be identified as black, white, and brown discolorations as well as by the presence of lichens, bryophytes, and herbaceous plants. In the evaluation of the physical properties of the stone lantern, the mean and maximum ultrasonic velocities were found to be similar in each direction. However, the lowest velocity on the east and south sides were found to be lower than those of other stone properties. It was found that physical damage to the stylobates resulted from water expansion in a freeze-to-thaw phenomena related to water content. Therefore, dismantling repair was carried out in the protection facility to restrict further water supply to the stone as much as possible.
