This article examines the characteristics of the royal tombs of the late Silla Dynasty with the statues of the 12 animal deities(Zodiac) and estimates the process of change. The features of the statues show a difference in their combination in terms of continuity and similarity of the object in their hands. In addition, there is a difference in the shape of the face of the stone statue, and differences are observed in the orientation and aspect ratio of the statue according to the sculptural method. The characteristics of these statues are somewhat different from the previously studied protected-stone and manufacturing techniques. For example, the Zodiac statues that are flattened from high relief to low relief are known to be decorated in realistic expressions, but they tend to be treated as separate conditions because they do not match the change of the stone. In addition, there was a characteristic that did not show regular changes, such as appearing and disappearing again when there was no balustrade in the tomb. Summing up the characteristics of each part, the Zodiac statues are largely divided into curved angles and flat angles according to the sculptural technique, and the head orientation and clothing of the statue are related. They are divided into two categories and can be viewed as having temporality according to the aspect ratio. These characteristic changes are consistent with the continuity of features and changes in the object in the hands of the 12 Zodiac statues. Therefore, the number of faces with protected-stone changes were gradually increasing in trend. As a result, there is a possibility that the Gujeongdong Square-shape Tomb and King Jindeok Tomb are earlier royal tombs than the Wonseong Royal Tomb. Therefore, the royal tombs of the late Silla Dynasty have a complete, tomb structure, containing the 12 animal god statues, ceremonial spaces(拜禮空間), Shindo(神道), stone statues(石像), and tombstones. This can be understood as a basic motif for the royal tomb structures of Goryeo and Joseon.

Host rock or the standing sculptured Buddha in the Yongamsa temple is macular porphyritic biotite granite, which has gone through mechanical and chemical weathering. The rock around the Buddha statue is busily scattered with steep inclinations that are almost vertically discontinuous planes with the strikes of $N8^{\circ}E$. Especially the development of the joints that cross the major joints causes the structural instability of the rock. The rock of the Buddha statue is separated into several rock blocks because of many different discontinuity. Thus it is estimated that the bed rock has not only plane and toppling failure but also wedge failure in all the sides. Since the differential pressure is imposed on the body of the Buddha in the host rock, it is urgent to give a reinforce treatment of geotechnical engineering for the safe of its structural stability. Very contact area of joints have turned into soil, which promotes the growth of weeds and plant roots, then aggravates the mechanical weathering of the rock. Thus conservational treatments should also be considered to get rid of secondary contaminants and vegetation along the discontinuities and to prevent further damages.

Wooden standing Bodhisattva in the collection of the National Museum of Korea (Bon 8239) was purchased as part of the museum's Central Asian collection during the Museum of Japanese Goverment General of Korea. The wooden statue exhibiting classical characteristics of Song Dynasty Buddhist sculptures is colored on the whone. The result of condition check for exhibition in 2014, it has severely damaged, with discoloring and exfoliation in color pigment and crack of wood observed in various areas. The object was therefore treated for conservation. A series of analysis were performed also at this time to determine the production technique and the materials, including testing of the X-ray penetration depth, X-ray fluorescence analysis and wood species analysis. This revealed that the statue was made by joining several separate pieces of wood. As for color pigments, the white pigment was either chalk (CaCO₃) or gypsum(CaSO₄·2H₂O), and the green pigment was emerald green (Cu(C₂H₃O₂)₂·3Cu(AsO₂)₂). The red pigment appeared to be lead red(Pb₃O₄) and the blue pigment was ultramarine blue (3Na₂O·3Al₂O₃·6SiO₂·2Na₂S). All the pigments were repainted in later eras. The analysis, indicated that the wood was derived from a tree of the genus Populus, family Salicaceae. The wooden standing Bodhisattva was repaired and reinforced with natural materials and was brought to a stable condition necessary for display.

This study focus on the surface deterioration diagnosis based on the material characteristics of Taean Dongmunri Maaesamjonbulipsang(rock-carved standing triad Buddha Statue) and the weathering environment analysis. Rock materials of the triad Buddha is coarse-grained biotite granite which is composed mainly of quartz, K-feldspar, plagioclase, biotite and muscovite. The triad Buddha was serious surface irregularity(13.5%), exfoliation(12.3%) and discoloration(46.6%), and the physical characteristics using ultrasonic velocity appeared fourth grade (0.59, highly weathered). Korean style wooden shelter of the triad Buddha(closed type) maintained high humidity environment (daily mean; 86.6%) than exterior environment, and appeared the possibility of deterioration by freezing-thawing because the temperature showed below zero temperatures in winter. The shelter was changed from closed-type to open-type to relieve the moisture problem recently. But the moisture problem is yet to be solved because surface water flowing along northern wayside is flowed into triad Buddha. Therefore, environmental control will need to stop inflow of water into triad Buddha.

This study demonstrates the consolidation effect of ethylsilicate consolidants considering material characteristics and weathering degree of Samneunggyeseongakyukjonbul(rock-carved Yukjonbul Buddha in Samneung Valley) in Namsan, Gyeongju. The buddha statue is composed of alkali feldspar granite and contains numerous sets of joint with exfoliation and granular disintegration, therefore the statue is necessary to be treated for surface strength. The laboratory and in-situ tests of consolidation effect showed more increase of ultrasonic velocity that KSE 300, a relatively highly concentrated consolidant, performed more increase of ultrasonic velocity and decrease of porosity than others after treatments in weathered granite. And the consolidated rock with OH 100 was more resistant to salt weathering. For the buddha statues, KSE 300 is more applicable to enhance surface strength because it showed higher consolidation effect for long term than OH 100 and the statues has not been weathered by salts.

The host rock of standing sculptured Buddha in the Yongamsa temple was macular biotite granite, which has gone through mechanical and chemical weathering. The principal rock-forming minerals are quartz, plagioclase, alkali feldspar, and biotite, the last two of which have been transformed into clay minerals and chlorite due to weathering processes. The bed rock around the Buddha statue is busily scattered with steep inclinations that are almost vertical and discontinuous planes with the strikes of $N8^{\circ}E$. The major joints have the strikes of N4 to $52^{\circ}W$ and N6 to $88^{\circ}E$ and the dips of 42 to $89^{\circ}$. Especially thee development of the joints that cross the major joints causes tile structural instability of the rock. The host rock of the Buddha image is separated into many different rock masses because of the also many different discontinuity, which group accounts for about $12{\%}$ of the rock. Thus it's estimated that the bed rock has not only plane and toppling failure but also wedge failure in all the sides. Since the earth pressure and the inclination pressure are imposed on the body of the Buddha in the basement rock, it's urgent to give a treatment of geotechnical engineering for the sake of its structural stability. The parts where serious fractures are seen should receive the hardening process using the fillers for stones. It's also necessary to introduce a landfill liner system in order to reduce the ground humidity. The rock surface of the Buddha statue are partly contaminated by lichens and bryophyte. The joints have turned into earth, which promotes the growth of weeds and plant roots. Thus biochemical treatments should also be considered to get rid of the vegetation along the discontinuous planes and prevent further biological damages.

This study is about the costume relics that were excavated from M10 of the 6th site, M13 and M14 of the 8th site among all the Runghai(龍海) ancient tomb sites that were known as the royal family's tombs of Balhae, which were built from the late 8th century to the early 9th century. These costume relics were also introduced in the academic journal of Chinese archaeology(考古) 6 in 2009. The summary of the results that focused on finding features of the costume relics and its meaning were as follows: 1. Male and female statues, both of which were excavated from the Runghai ancient tomb sites, had the shape and composition of the government official's costumes such as the Danryeong(團領), Bokdu, and Gwadae. The female's hairstyle and accessories were quite similar to other costume relics of Balhae. In particular, the male statues wearing the Danryeong and Bokdu were considered as the normal figures of government officials of Balhaeafter the mid 8th century. 2. The female statue wearing the male attire is considered as a maid, and we can confirm that women dressing up like a man was a popular trend in Tang(唐), and this trend was introduced to Balhae. 3. The back flap(垂脚) of Bokdu that the male statue is wearing in M10 of the 6th site, has a shape that has not been found in the ancient relics of both Balhae and Tang. Therefore, it is considered as a unique shape of Bokdu of Balhae. However, it needs to be observed more and discussed in the future. 4. In regards to the Gwadae, the outside of the Gwadae is decorated with jade and has an embossed carving that is gold inside. The Gwadae of the Runghaisites has a unique design and it is distinguished from other ancient relics. 5. The gold trefoil crown and the leather conical hat that were found in M14 of the 8th site can be seen as the basic composition of official's hats in ancient Korea. Also, the motif of the gold trefoil is closely related to Anthemion that is often seen in the relics of the Three Kingdom period. Thus, we can assume according to this important finding that the style of ancient Korea official's hats came from either the king or a royal family of Balhae after the mid 8th century.

The subject of this study is the Maae Buddha statue in granodiorite of the Mesozoic Cretaceous period, which is concerned about stability as a standing stone cultural property located in ◯◯-dong, Gyeongsangbuk-do. For stability analysis, three-dimensional face mapping, geological properties of joints, three-dimensional scanning, ultrasonic velocity, polarization microscopy, electron microscopy analysis and XRD analysis were performed. In addition, the safety factor of the Maaebul was calculated by analyzing the damage status investigation, stereographic projection analysis, rock classification, and limit equilibrium analysis. The types and scales of damage and possible collapse by section depend on the degree of weathering of the rock and the orientation and characteristics of the joints, but wedge-failure and toppling-failure are expected to be small-scale. The safety factor of Maaebul in dry and wet conditions is less than 1.2, so stability is concerned. The types of damage were mainly observed, such as exfoliation, cracking, granular decomposition, and vegetation growth. The Maaebul rock is granodiorite, and the surface discoloration materials are K, Fe, and Mg. The 4 sets of joints are developed, J1 is tensile joint and the others are shear joint. The uniaxial compressive strength estimated by ultrasonic exploration is 514kgf/cm2, which corresponds to most soft rocks and some weathered rocks. Rock classification(RMR) is estimated to be grade 5, very poor rock mass. These technique along with the existing methods of safety diagnosis of cultural properties are expected to be a reasonable tool for objective interpretation and stability review of stone cultural properties.

Buddhist Architecture should be set for worship and an ascetic life, which is its main function as it is a religious facility and its space and form can be considered as means to achieve efficiently a religious function. Every religion concludes its religious function through its ideas and form of faith based on scriptures and religious precepts. The thing should be paid attention to from this point of view is how Buddhist doctrines are reflected on the architecture and the background recognition about the fundamental doctrines and religious system should be preceded to clarify it. Existing researches have studied the characteristics of Buddhist temples on the point of functional view and architectural spacial view through phenomenal ways. Though fruitful results bore about the Korean space through that way, more internal viewpoint is required to clarify the fundamental regularities and spatial concepts indwelling in temple architecture. Considering what structural elements were required to compose one space in traditional Korean architecture is the fundamental subject and important. This thesis searches architectural characteristics through inquiring about the main building and annexes and understanding symbolic characteristics about the arrangement of the Buddhist statue and solemn things in the Buddhist temples of tangible cultural assets or above located in Seoul area.
