This study was focused on digital restoration and structural stability evaluation applying 3D scanning system of five-storied Magoksa temple stone pagoda in Gongju. For these, the digital restoration of the pagoda was completed using laser scan data which is measured 16 directions and data processing program of 7 stages. As a result of digital restoration, the overall height and width of stone properties showed a little difference in directions and the width of roof stones appeared very high difference of each floor. The width of pagoda body become smaller to the fifth floor, but gradual decrease rate showed irregular characteristics. Also, as result of 3D image analysis for structural stability evaluation, the displacement occurred toward northwest in second body stone to upper final stone except for central axis of the first body stone which inclines toward southwest. Such 3D image analysis is required quantification of survey method and should be applied to various field such as quantitative damage maps in order to utilize a conservation of stone cultural heritages, continuously.

The findings of a 2017 safety inspection of the Three-story Pagoda from the Goseonsa Temple site in Gyeongju suggested the possibility that the stone for the second story of the pagoda may have been rotated after the pagoda was disassembled for removal from its original site in 1975. The materials from the pagoda were investigated using photographs and other relevant data from both the Japanese colonial period and from around 1975. The analysis found that the materials of the pagoda were not changed after analleged reconstruction in 1943, but that during the process of relocating the pagoda in 1975 the body of the second story was indeed rotated counter clockwise by 90 degrees and one of the four stone elements making up the first-story roof was exchanged with a part from the second-story roof. In order to discover whether the materials had been incorrectly placed, each part of the pagoda was precisely measured and the elements of the roofs were virtually reconstructed using 3D scanning data. The investigation did not find any singularities with in the components of each roof; the four part sof the first-story roof were 75 to 76 centimeters thick and those for the second-story roof were 78 to 79 centimeters thick. The connections between each part of the roofs also appeared natural. This seems to indicate that there was indeed an undocumented repair of the pagoda at some point between its creation and 1943 and an error that took place during this repair was corrected in 1975. In addition, the study suggested a possibility that the body of the second story was rotated counter clockwised to a change in the locations of parts of the two roofs.

In Korea, only a few wooden pagodas are extant because some wooden pagodas were lost due to artificial environment like war. Fortunately, only Eight Depictions Hall(Palsangjeon) in Beobjusa temple and main hall of Ssang-Bong Sa the main temple are extant. Though main hall of Ssang-Bong Sa the main temple shows old style in construction and outstanding creativity, survey and investigation for the hall have been poor. Accordingly, this study investigated pillar part, bracket structure part, and roof part composing pagoda body section which actively reflects structure and design skill compared to floor or upper part. And for better understanding, in the part that is similar to pagoda body section of main hall or needs examples, wooden pagoda in China or Japan was referred. Through this investigation, it was known that unique skill applied to main hall of Ssang-Bong Sa the main temple is based on plane in one room ${\times}$ one room - Ssang-Bong Sa the main temple has common form of wooden pagoda in appearance.

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.

Buddhism was introduced to Gyeonggi-Do early on and thus created various types of Buddhist culture there. Since the introduction of Buddhism into Gyeonggi-do, the there has been continuous construction of stone stupas. More stone stupas were built in southern Gyeonggi than in northern Gyeonggi-do. In particular, Anseong, Icheon, Yongin, and Yeoju were centers of construction. Looking at the characteristics of each period, stone stupas remain from the Unified Shilla Period to Joseon, indicating that stone stupas were steadily built during this period. The stone stupa corresponding to the Unified Shilla Period is meaningful in that it shows the northern limit of Shilla Buddhist culture. Since then, the stone stupas of the Goryeo Dynasty were actively constructed in the southern part of Gyeonggi-do in the early Goryeo Dynasty. By the late Goryeo Dynasty, the stupas were built throughout Gyeonggi-do, indicating that the construction of the stupa was active. In the Joseon Dynasty, stone stupas were built in temples near Hanyang and deeply related to the royal family. Stone pagodas were erected mainly on major traffic routes. Stone stupas built in Gyeonggi-do have a variety of artistic and historical significance.

The west stone pagoda of Gameunsa temple site(National Treasure No. 112) has been seriously damaged by surface weathering, and conservation treatment is needed. In the second story body stone, vertical cracks developed parallel to the main compressional axis. The vertical cracks seem to grow much more with the compression. Chemical and biological weathering along the vertical cracks could have enhanced the crack growth. In the third story capstone, the surface cracks strike toward NE and NW directions, which are intersecting each other. In the eastern and southern parts of the third story capstone, lots of vertical cracks develop along the lines from the axial center to outer rim, whereas horizontal cracks are easily observed at the outer rim of the capstone. On the other hand, a few horizontal cracks develop in the western and northern parts of the third story capstone. This fact indicates that the compression along the vertical axis is not uniform in direction. The west stone pagoda leans toward the east and the south, so it is considered that compression by deviatoric stress prevailed at these directions.

The position of each part of the Ten storied pagoda of Gyeongcheonsa has been changed because of illegal dismantlement and assembling throughout the history. There remain carved letters in the part of pagoda, which let us know the incorrect assembling of the parts, however, we still don't know the reasons. The pagoda has been under conservation process by the conservators from Conservation Science Division in the National Research Institute of Cultural Properties. It is one of the main purposes to find an original structure of the pagoda by appropriate assembling. The existence of iconography and carved letters are very useful in the conservation process. Mis-assembled parts are mostly in the pedestal of the Chinese letter('아') and in the bodies up to third floor. The iconography of the pagoda has many similarities to the Ten storied pagoda of Wongaksaji.

We performed conservation treatment for the sarira reliquary from the pagoda of Hwangnyongsa temple site. The sarira reliquary is in the shape of gilt-bronze octagonal miniature pagoda. Through radiography, it was newly proved that a radial design exists on the roof part. The gilded layer was plated with amalgam. Each part was plated first before being put together. We restored the lost parts and made supports, and then assembled it in the following order: base, upper part of the base, shaft and roof part.

Until now, most studies regarding stone pagodas of the Honam region have been about stone pagodas with Baekje style because it was the territory of Baekje. However, after reviewing the designated cultural properties, I found that among the 94 stone pagodas in the Honam region there are 15 stone pagodas with Baekje style built in the Goryeo Dynasty and 34 stone pagodas with Silla style. So far, most research efforts have been concentrating on stone pagodas with Baekje style. Through a review of stone pagodas with Silla style, I sought to reveal new aspects of the pagodas in the Honam region. After reviewing the placement of pagodas, I found stone pagodas with Silla style were built mostly in South Jeolla Province during the Unified Silla period. However, in the Goryeo Dynasty stone pagodas with Silla style were erected throughout the Honam region. This shows enhanced Buddhist control over the Honam region than in the previous period. It can be verified especially in Gimje, Jeongeup, Sunchang, Damyang, Yeongam, and Gangjin, where stone pagodas with Baekje style and stone pagodas with Silla style coexist. The types of stone pagodas with Silla style in the Honam region can be divided into two. There are 21 pagodas with two-story foundation, and 12 with single foundation. They seem to have inherited characteristics of the two-story foundation of Silla pagodas. Two pagodas with single foundation were made of a single rock or natural rock for lower foundation. Regarding the body of the pagoda, there are 21 three-story pagodas and 12 five-story pagodas. 25 pagodas have first floors made of a single rock. These are likely to be in the tradition of Silla pagodas. However, the lower part of the roof stones vary as there are three, four, or five-tiered ones. Overall, 12 out of 16 pagodas with middle column in foundation, and 15 out of 21 three-story pagodas are located in South Jeolla Province. This proves that stone pagodas in the South Jeolla Province well maintained the tradition of Silla and became popular.

The three-story stone pagodas in Hyeon-ri and Hwacheon-ri,Yeongyang Gyeongsangbuk-do are stone pagodas that exhibit the typical style of Unified Silla. The two pagodas are believed to have been built in the mid- and late 9th centuries at the latest, considering the style of the three-story roof stone on top of the double-tier base. This is also confirmed by the reliefs carved at the base and the first-story of the pagoda. The Four Heavenly Kings and the Twelve Zodiacal Animal Deities were first combined in the late 8th century in the stone pagoda at the Wonwonsa Temple Site, and the Eight Classes of Divine Beings was also the most popular carved pagoda reliefs in the 9th century. However, the two Yeongyang stone pagodas are characterized by a combination of the Four Heavenly Kings (1st story), the Eight Classes (top base), and the Twelve Zodiacal Animals (lower base), and the stone used for the pagoda consists of sedimentary rocks of the sandstone family, which comprise most of the geological strata in the Yeongyang area, rather than ordinary granite. The new combinations of the three types of guardian deities and the Eight Classes changed from seated to standing poses is interpreted as an attempt to enhance the Buddhist faith and cultural status of the Yeongyang area, along with the fact that the stone pagoda was built using local natural materials. The Eight Classes of the Yeongyang stone pagoda does not follow the two types of arrangement of the pagodas with the Eight Classes, but some of the deities have been relocated to a new location. Composed of AsuraGandharva on the east side, Naga-Mahoraga on the south, Deva-Garuda on the west, and Kimnara-Yaksa on the north, this form can be classified as a unique 'third layout of the Eight Classes' in the Yeongyang area. Such changes in the shape and posture of the reliefs reflect a new perception of the pagodas. The reason why the Gandharva and Yaksa statues were carved on the east and north sides, respectively, was because they were deemed subordinate to the Four Heavenly Kings, and the fact that the Naga and the Mahoraga were carved on the south side was presumed to have influenced the geographical location of the two pagodas on the northern side of Banbyeoncheon Stream. The Hyeon-ri and Hwacheon-ri three-story stone pagodas inherited the tradition of typical Unified Silla-period pagodas, while also bearing their own new regional characteristics.
