This paper is a study on structural measurement by using a terrestrial camera. The aim of this paper is to understand the method of a composition by analyzing the geometrical compositive ratio of threestoried pagodas at Gamun-Sa, Gosun-Sa, Bulguk-Sa, Seated iron Buddha in Kwang-Jn, and Main-Seat Buddha at Sukkuram Cave-temple. Measured data and contour maps are accurately obtained by means of photogrammetry, and the following points are able to he found by analyzing them. At first, for Stone Pagodas. the breaths of the Okgesuks are made to the ratio, 8 : 7 : 6. And when an equililateral triangle and an 45$^{\circ}$ isosceles triangle are drawn of which the bases are the length of the upper Gabsuk, and then a circle is drawn whose radius is the length between the vertexes of the two triangles and its center is the vertex of the former the circle passes the upper line of the third Oksin. Also it can be found that an $70^{\circ}$ isosceles triangle being drawn at base line, the triangle passes the edge point of the upper Gabsuk and the center of the third Okgesuk. Also for Budha statues, it can be found that circles whose center is that of eyes can be drawn, and if 2 lines which pass the shoulder and the center of Buddha's body are extended, they intersect the knees.

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.

The Three storied Stone pagoda in Gameunsa Temple site, one of the early staged stone pagodas, has been known as a standard for Silla stone pagodas. A stone pagoda is not only a stone art work and but also a stone structure. Most studies and investigation of the stone pagoda has done mainly based on style and chronological research according to an art historical view. However, there is not an attempt to research the stone pagoda as a stone architecture. Most Korean experts at the stone pagoda has art history in their background. Engineers who can understand the structure of the stone pagoda are very limited. More architectural and engineering approach is need to research not only art historial understanding but also safety as a structure. We can find many technical know-how from our ancestors who made stone pagodas. 1. To reduce any deformation such as relaxation and sinking of BuJae which is caused by a heavy load, the BuJae (consist of a foundation stone and lower stereobates) should be enlarged. 2. A special construction method for connection between Myonsuk and Tangjoo was invented. This unique method is not used any longer after the Three storied Stone pagoda in Gameunsa Temple site. 3. The upper BuJae and the lower BuJae are missed each other by making a difference of Okgaesuk and Okgaebatchim in size. It is done for a distribution of perpendicular load and a prevention for relaxation of BuJae. 4. The center of gravity in the BuJae is located to the center of the stone pagoda by trimming the upper surface of the Okgaebatchim into a convex shape. The man who made stone pagodas had excellent knowledge on the engineering and techniques to understand the structure of the stone pagodas. We can confirm it as follows: the enlarged BuJae, dislocated connection between upper Bujae and lower BuJae, and moving the center of gravity close to the center of the stone pagoda.

The Uiseong Tapriri Five-Storied Stone Pagoda (National Treasure No. 77) is typical stone cultural heritage in Unified Silla Dynasty, Korea. The pagoda has been occurred black, brown discoloration and microcrack, exfoliation, granularity decomposition with white discoloration because of continuous weathering. As the results of analysis for the contaminants, chemical weatherings are generated that black contaminant by manganese oxide, brown contaminant by iron oxide, white contaminants by gypsum and taranakite. And physical weatherings, such as microcrack, exfoliation, are occurred by salt(gypsum) crystallization. Therefore, these need to remove the contaminants according to the conservation treatment manual, and regular monitoring using P-XRF to preserve long-term the Five-Storied Stone Pagoda at Tapri-ri, Uiseong.

The Bunhwangsaseoktop is the oldest stone brick pagoda in Silla Period. The pagoda body is made by piling small brick-shaped stones trimmed from black andesite and the first-story core has a shrine, which is made by granite. In 1915 it was repaired on a large scale, but now is severely damaged. Many kind of the stone decay like flaking, granular disintegration have occurred especially on the granite surface of the pagoda. In this study have been investigated the stone decay type and its cause in relation to efflorescence on the body part. Various analysis show that the deterioration on the granite is due to the same materials that lead to efflorescence on the body stone surface. The soluble salt like sodium nitrate, calcium sulfate and sodium sulfate come from white joint mortar. This salt solution is recrystallized in the outside of the pagoda, but most of them flow down with rain. In This process the porous granite absorbes the dissolved salts with moisture into the inside by capillary action. In order to reduce this problem, therefore, white joint moral is changed with other less soluble materials. And it is necessary to take steps to prevent water from seep into the inside of the stone, because this water dissolves the white joint mortar.

The Bunhuangsa stone pagoda, constructed in AD. 634, National Treasure no. 30, has been named as 'brick-copied pagoda' since the Japanese-ruling period by scholars. It is said that the Chinese brick pagoda was its precedent model, however the Bunhuangsa Pagoda is the oldest of all the Chinese-style brick pagodas except one, the Sungaksa Pagoda. The Chinese pagoda cannot have been a precedent model to copy due to its complex detail of wood vestige, as the Bunhuangsa pagoda is simple form without ornament. Domestic brick pagodas cannot have been a precedent model to copy as well, because all the domestic brick pagodas are younger than the Bunhuangsa Pagoda. Therefore, the terminology 'brick-copied pagoda' is a fallacy; it is rather that later brick pagoda copied the precedent the Bunhuangsa stone pagoda. The Bunhuangsa Pagoda is simply a piled-up pagoda of thick or thin, big or small slates of stone, facing only one smooth side and therefore needing nothing to relate to brick. The originality of the pagoda is more related to simple piled-up Indian stone stupa rather than Chinese brick pagoda. The roof form of its gradually stepped projection comes from the harmika of the summit of Indian stupa. Contrary to general history, old Silla Dynasty imported Buddhism directly from India by sea. From written national history and by temple foundation history, the Indian Buddhism evangelist possibly made influence to the erecting of temple and pagoda. The original wrong terminology has made a harmful effect gradually to the naming of mass-styled stone pagoda of only carved stepped-roof form after brick-copied pagoda. The false term 'brick-copied pagoda' should be discarded, which comes with superficial observation based on toadyism to China and colonialism to Japan. Instead of the fallacious term, this paper suggests multi-storied 'piled-up pagoda with slate stone.'

According to the previous studies about Shilla's cremate grave, in the process of importing the cremate grave, there has been correlation with Chinese Buddhism, and there have been a lot of mentions about the change of the grave, Yinwha(Stamp) patterns and its existence, and about the characteristics of the vessels to contain the bones. The cremate grave is categorized into two-parts type and mono-type, depending on the dead person. The cremate graves that are in local areas such as Wang-Gyeong, show difference in types. The typical vessel to contain the bones, called "Yeongyeol Gori Yoogaeho" is again proved to have existed from A.D 8c. ~ A.D 9c., judging from the Yinwha pattern stamp's existence. Yet, the Yeongyeol Gori Yoogaeho from 9th century used the patternless pottery, also seen from the Won-wha 10 yeon-myeong cremate grave. Due to the prosperity of Buddhism, when the "Mukuchonggwang Taranikyong(Sutra)", translated into Han language in 704 at Dang, was imported into Shilla, the funeral ceremonies of Shilla people changed from making cremate graves with vessels or scattering the bones in oceans, into building stupas in temples with hopes and wishes to bring oneself and family's fortune and the next life of the dead. As a result, the meaning of "Grave" disappeared for the cremate graves, and rather the ceremony changed into scattering bones and wishing fortunes for the dead person. In other words, the ancestor-worship ceremony which was focused on the tomb changed into commemorating the ancestors and wishing individual fortunes by the religious assembly in temples and the building process of stupas. In conclusion, this social change was the cause of the extinction of stone chamber with tunnel entrance and the tombs such as cremate grave.

The Gyeongju Bunhwangsa Stone Brick Pagoda, which was built with bricks of andesite, is the oldest brick stone pagoda of Silla period. The damage patterns in the stone pagoda are pollutants such as white crust, black crust, discoloration, soil adsorption, and microorganisms, and repair materials. The damage pattern of structural factors in the Stone Brick Pagoda is a bulging phenomenon. According to the X-ray diffraction analysis, white crust are mainly consist of calcite ($CaCO_3$) and thermonatrite ($Na_2CO_3{\cdot}H_2O$) that evaporite finds in nature. Damage pattern varies depending on location of stone pagoda. The pollutants are first story body of pagoda. The microorganisms are confirmed at base, lion statues, first and second story capstone, and repair materials observed at base. The bulging phenomenon appeared on the first story body of the pagoda. Occupancy rates by damage type were higher in the order of microorganisms, pollutants, repair material, bulging phenomenon, and peeling. The highest percentage of individual damage patterns were black microorganisms (39.3%), followed by lichen (17.9%), discoloration (8.0%), white crust (5.5%), cement mortar (5.1%) and peeling (3.1%).

The sarira reliquary excavated as a lot of fragments were restored by conservation treatment by us. The sarira reliquary was made using fine techniques such as chasing work and engraving work, etc. The analysis of base metals showed that different materials had been used on decorative parts in consideration of the casting and forging technique. Gold granules $(97wt\%\;Au)$ of the small bell were adhered by using a soldering material $(85wt\%\;Au,\;10wt\%\;Ag)$. The lead isotope analysis of lead glass $(74wt\%\;PbO)$ revealed that it agreed with the lead mine in the middle of south area in Korea.

Korean pagodas were constructed in the shape of a wood pagoda, brick pagoda, stone pagoda, etc. On the other hand, the currently remaining traditional pagodas are those having nonflammable materials, such as brick, stone, etc. Compared to the stone pagoda, there is data regarding brick pagodas, but there is little literature data on how to construct these pagodas. This appears to be because there are relatively few Korean brick pagodas currently remaining, they are locally restricted, the material limit is not overcome, pagoda's historical and regional problems have not been analyzed, and pagoda construction is centered on pagoda construction. Therefore, this study examined the local cultural characteristics on the construction of brick pagodas. As a result, cultural exchange between Korea and China was performed through the silk road and there was a marine route for cultural exchange. Such exchange was shared with the East Asia area as well, which can be found by comparing remains at related areas. Exchange with China can be mentioned as the selective exchange of local powers as well as blind learning. Second, brick pagoda were constructed in Korea because of the good quality soil easily. Uisang's Hwaeomjong was negotiated with the main power not agreeing with Buddhism, which was popularized and the local power. Third, brick pagoda construction was influenced by negotiation related between Balhae and Silla, in which the ethnic influence was locally affected and could be mentioned as being a culturally selective result transferred from China. As a result, brick pagodas can be oriented by forming a unitary state rather than a small country within China's influence range as well as cultural transfer through the silk road.
