The foundations of ancient wooden pagoda consist of the stylobate soil, exteriors, stairways and etc. The factors were different according to the time, region and the architects. As a result of many archaeological researches, we have the data of horizontal gutters as a part of the foundations of ancient wooden pagodas in Gogureyo, China, Japan. But so far archaeological researches have not revealed such data in Baekje and Silla~Unified Silla period wooden pagodas. In genarally, the eaves must protrude as much as the outer line of the foundation to protect its upper side from rain. The purpose of the aforementioned horizontal gutter was to protect the foundations of ancient wooden pagodas. In this article, we call this horizontal gutter the Naksubaji. After researching many archaeological findings of ancient wooden pagodas of China, Korea and Japan from 5th century to 7th century, it is suggested that the Naksubaji was installed to wooden pagodas of Baekje period in 6th century and Silla~Unified Silla periods in 7th century. In wooden pagodas of Baekje period in 6th century, Naksubajis were found in wooden pagodas of Gunsurisaji temple site, Neungsanrisaji temple site, Wangheungsaji temple site. Especially in case of the Wangheungsaji temple site, presumed line to make stylobate of wooden pagoda in Baekje period was confirmed by archaeological research and this case is similar to the early period wooden pagodas in Japan. Goryeocheok(ruler used in the Three Kingdoms) was used to construct wooden pagodas. According to the restoration plan of wooden pagodas to verify the protrusion of eaves, the ratio of the length of the foundation:the length of 1st storied building:the length of the center:the length of the corner was 4.9:2.7:1:0.9 between Gunsurisaji temple site pagoda and Wangheungsaji temple site pagoda. Also I found tne same length of tne 1st storied building between Gunsurisaji temple site pagoda and Wangheungsaji temple site pagoda. Therefore the exact scales and planning were adapted to the establishment of wooden pagodas in 6th century in Baekje period. But the Naksubaji was not producted after 6th century in Baekje period. Because the big wooden pagoda had been appeared, they were needed other style of the foundation. In wooden pagodas which were made in Silla~Unified Silla periods in 7th century, I found the Naksubaji in wooden pagodas in Youngmyosajl temple site, Hwangnyongsaji temple site, Sacheonwangsa temple site. The line of stone in Youngmyosajl temple site, the 2nd line expressed the area of pagoda, the relative analysis of the lower foundation between Neungsanrisaji temple site pagoda and Sacheonwangsa temple site pagoda were examined the Naksubaji. In Silla~Unified Silla periods, the establishment of wooden pagodas was started at 7th century. So they had the exactly details of wooden pagoda, but we had no data of the Naksubaji after the time made Sacheonwangsa temple site.

It is hard to predict the mechanical characteristics of discontinuous stone masonry structures by the static analysis method, because of irregularity of face stones and also due to randomness of backfill materials. Inversely, one can estimate the mechanical characteristics by comparing the natural frequencies between measured and computed. The aim of this paper is to investigate the computational modeling method of ancient stone arch bridges in Korea and to find the factors influencing their dynamic characteristics. The results revealed that the rigidity of spandrel walls and backfill materials are the most important factors influencing the natural frequencies of stone arch bridges.

This paper studied the 3D modeling process for the restoration of the 'Three-story Stone Pagoda of Bulguksa Temple in Gyeongju', a stone pagoda from the Unified Silla Period, using artificial intelligence (AI). Existing 3D modeling methods generate numerous verts and faces, which takes a considerable amount of time for AI learning. Accordingly, a method of performing more efficient 3D modeling by lowering the number of verts and faces is required. To this end, in this study, the structure of the stone pagoda was deeply analyzed and a modeling method optimized for AI learning was studied. In addition, it is meaningful to propose a new 3D modeling methodology for the restoration of stone pagodas in Korea and to secure a data set necessary for artificial intelligence learning.

The Five-story Stone Pagoda from the Dongsa-ri Temple Site in Buyeo, dated to early Goyeo Dynasty, is valuable in that it is the southernmost example of the capital Kaesong pagoda style. This pagoda exhibits characteristics of the central Goryeo style featured in the pagodas built in and around the capital Kaesong, such as the diagonally curved section of the support for the cover stone above the upper stereobate. It also shares stylistic affinities with eleventh-century stone pagodas. The ansangmun (elephant eye patterns) in the lower stereobate of the Dongsa-ri Five-story Stone Pagoda resemble those in the pedestal of the Stone Seated Buddha (which was likely repaired in 1028 during the reign of King Hyeonjong), at the Jeongrimsa Temple site in Buyeo. It also reflects elements found in the flagpole supports from the Cheonheungsa Temple site in Cheonan. The sculpting techniques used in these patterns are also similar. Such congruencies suggest that the Dongsa-ri Five-story Stone Pagoda was built in the eleventh century. The Dongsa-ri Temple Site in Buyeo, located near the Geumgang River, served as a principal route for transporting grain-tax during the Goryeo Dynasty. It was also situated along the way to the Goryeo royal temple, Gaetaesa Temple. The geographical significance of the site and the extensive repairs undertaken at Jeongrimsa Temple during the reign of King Hyeonjong (r. 1009-1031) of the Goryeo Dynasty appear to have impacted the production of the Dongsa-ri Five-story Stone Pagoda. The Dongsa-ri Five-story Stone Pagoda also bears stylistic resemblances to the stone pagoda and flagpole supports found at neighboring Cheonheungsa Temple, which is presumed to be related to the establishment of Honggyeongsa (or Honggyeongwon) Temple in 1021 in Cheonan. This indicates the route of the transmission of the Kaesong pagoda style. The Five-story Stone Pagoda from the Dongsa-ri Temple Site pays testimony to the cultural accomplishments of eleventh-century stone artworks in Buyeo and adjacent regions. This pagoda embodies the majestic and assertive aesthetics that define of the Goryeo Dynasty, as do early Goryeo colossal Buddhist sculptures, including the Stone Standing Maitreya Bodhisattva at Daejosa Temple in Buyeo, the Stone Standing Buddha Triad at Gaetaesa Temple in Nonsan, and the Stone Standing Maitreya Bodhisattva at Gwanchoksa Temple in Nonsan. All of these bear similarities to the massive stone lantern and pagoda at Hyeonhwasa Temple in the capital Kaesong. The production of the light, sleek, sharp, and sophisticated Dongsa-ri Five-story Stone Pagoda is presumed to reflect the maturity of the cultural competence of the people in Dongsa-ri, Buyeo under the influence of Buddhist culture from the capital Kaesong during the eleventh century, a time marked by active cultural exchanges among regions.

In the 7th century, Sachunwang-sa temple had two extra building-sites behind the Main hall. These two building-sites were found to be in peculiar form different from any another existing stone bases. The stone bases of northern put of these building-sites were decorated to molding as the protruding comers of eaves, which was pierced into a circular hole, and was carved into a form of Gomeck-ii(the stone bases lot supporting the wall). The northern building of sachunwang-sa temple was found to be used as the altar following munduru(文豆婁) method, through the observations of the archives of Samkukyusa(三國遺事) and the Abhiseka stura(skt. 灌頂經). The molding as the protruding cornets of eaves of stone bases was shaped as the roof of a building and the carving of Gomeck-ii gives a proof of the existence of the wall between columns in the altar. The hole of the stone bases protected the wooden cylinder of munduru from the exterior world. The author concludes, through this research, that the altar of Schunwang-sa temple was used lot the religious service during the war for worthship and protecting from the enemies. Also he concludes that these buildings must have been in wooden pagodas constructed upon a square plan, that is with both front and side width equal, haying a quite small scaled and low floored building with its first floor closed on all sides, being different item the usual form.

The purpose of this study is to investigate the significance of Buddhist stone art in the cultural zone of Mt. Bukhan. Mt. Bukhan witnessed the prevalence of Buddhist culture in and around it since the introduction of Korean Buddhism and served as the center of Buddhist culture in the nation, where new Buddhist temples continued to be built from the Three Kingdoms Period to the Joseon Period. Of the characteristics of its Buddhist culture, it is very noteworthy that the construction of military temples in and around it in the latter half of Joseon supported the function of Buddhist temples as basic places of worship. These military temples were closely related to the mountain's geopolitical location, traffic routes, and position in the national defense system-- its mountain fortress was an important defense facility. The stone art works of Mt. Bukhan can be categorized into various types, including stone stupas, stone pagodas, rock-carved Buddhas, stone Buddhas, towers and monuments (stone monuments), stone lanterns, flagpole supports, and rock-carved sarira pagodas. There are diverse types of stone art left on the mountain. As for its period characteristics, it is clear that the Buddhist art of Silla spread even to the Gyeonggi region, and that most of the works of stone art were created during the first half of Goryeo and the latter half of Joseon. Starting in Goryeo, the Buddhist temples of the mountain maintained close relations with the royal court by operating as the royal buddhist shrine for the royal family. In the latter part of Joseon, the construction of the Bukhan mountain fortress became the most important opportunity to produce stone art. As for the distribution of the stone artwork, it was usually created in the west part of the mountain from Unified Silla to the first half of Goryeo and in the southern and eastern parts of the mountain from the latter half of Goryeo to the latter half of Joseon. It is estimated that central Buddhist temples of the mountain changed due to Silla's military goal of advancing toward the west coast along the Han River in its early days and the construction of the Bukhan mountain fortress in the latter half of Joseon to protect the capital city. Finally, the stone art of Mt. Bukhan holds very high significance in art history because various types of stone art continued to be created on and around the mountain, the stone artwork of the mountain reflected representative styles for each period, and e rare and ofthe works produced on the mountain exemplified rare and unique styles.

It was identified by the excavation that architecture remains were confirmed buddhist temple consist of ruins of main building of a temple, auditorium site, ruins of stone pagoda, embankment, pedestrian Facilities and drainage etc. in the Gwangmyeong-dong site. The site has been held temple arrangement with 1 main building of a temple, twin Pagodas from the Unified Silla period to Goryeo dynasty. The temple constructed after that was destroyed the architecture in the Unified Silla period. It seems that aristocrat or royalty power of within group of the nearby remains of city which was constructed in the Unified Silla period build and visit the temple. Considering there are excavations, it assumes that the temple had been constructed during the last days of the Unified Silla, was closed up during the mid-Goryeo Dynasty.

Black surface layers collected from stone pagodas were analyzed to study the effects of carbon compounds on the blackening of stone surface layer. The total amounts of carbon was measured through elemental analyser. Organic and elemental carbon were measured by combustion ihrornatographic $CO_2$ determination after elimination of carbonates carbon with acid treatment. The elemental carbon concentration in the black surface layer measured 0.52wt.%. This value is not sufficient to explain the complete blackening of stone surface. To trace the origin of carbon in black surface layer on the stone pagoda, aerosol samples for PM 10 were collected at the near sites of the pagoda. The major components of them were soluble ions(42.8wt.%), carbon(38.4 wt.%) and crustal matter(16wt.%). From the high content(13wt.%) of elemental carbon in aerosol ran be deduced that it may be a prime origin for the elemental carbon in the black surface layer on the stone pagoda. The crustal matter in aerosol can be also a origin of silicate mineral in black surface layer and plays a important role in the darkening of black surface layer.
