This study was intended to define the spatial concept of the boundary structure of the architectural space as well as evaluate the Hyangdan which well represents the features of Korean traditional building in such a way of reviewing the building structure of Korean traditional residential space. The boundary is categorized into visible boundary and invisible boundary which was also functionally classified into the features of isolating, passing, mediating and overlapping. The major elements comprising the boundary structure was analyzed by the characteristic of the pattern so as to define them as the concept of surrounding, duality, hierarchism, continuity and overlapping. Based on such concepts, a boundary structural characteristics of Hyangdan were reevaluated and outlined as follows. The surrounding feature was seen through the outer side of the structure surrounded, two courtyards and eaves, and a duality showing both the closure of main house and openness of detached house was seen through the characteristics of surrounding structure. And the continuous activities toward the inner room and the empty space to link them in a systematic way and repeatedly aligned rooms reveal the overlapping as continuous and transitional space. And finally, an elevated stylobate demonstrates the hierarchical features of the structure.

This study examined the structural characteristics of the royal tomb equipped with only rail stones in the early Joseon Dynasty. Bongneung(封陵: the burial mound of royal tomb) equipped with only rail stones was constructed from 1468 to 1632. During this period, Hyeongung(玄宮: the underground chamber for the coffin of the king or queen) was constructed with lime. When the Hyeongung is completed, the soil is covered with a thickness of 1 foot parallel to the ground surface. On top of that, as the base of the Bongneung, the rail ground stone is constructed with a height of about 1.5 to 2 feet. The inside of the rail ground stone is also firmly filled with soil. On top of this, semicircular lime is installed with a convex center. Lastly the soil is divided and compacted several times to form a hill, and then covered with grass to complete the Bongneung. The notable feature is that between the Hyeongung made of lime and the Bongneung made of soil, the rail ground stone serves as a stylobate with the inside compacted by the soil.

The grade of East Asian architecture is generally classified by the size, the shape of the roof, and the type of bracket set. The craftsmanship of columns, beam, purlin, stylobate, column base stone and paintwork is also a contributing factor for such classifications. These classifications can be found not only in historical documents such as 「Oksajo(屋舍條)」 of 『Samguksagi(三國史記)』 but also in 「house details regulations of residential architecture(家舍規制)」 of Joseon Dynasty. However, there are differences in detailed designs among the same grade of architecture regardless of the classification. In this research, the Palace, the Royal Residence(宮家), and the Jaesil(齋室) are considered as the Palatial Buildings and Royal Residences. And the advanced architectural o details which appear only in the Royal Architectures are defined as the 'The Architectural Crafts as a Code of Manners'. The Architectural Crafts as a Code of Manners is detailed design, which can be seen as fabrication of materials and supplementary factors. The Architectural Crafts as a Code of Manners used in the Palatial Buildings and Royal Residences reveal the types and their historical changes. This research will present a basis for the repair and restoration of cultural heritages to be carried out in the future, and also prevent them from further damages, thus help to preserve the cultural heritages.

The wooden pagoda sites which have been confirmed in Baekjae's former territory so far have flattened surface of the earth or foundation pert made by digging up the earth. In particular, the latter is found more often in the pagoda sites of Baekjae, which is essential and absolutely necessary because of the characteristics of pagoda structure. The wooden pagoda sites with foundation part made by digging up the earth under the stylobate are found at Yongjeongli ruined temple site of Woongjin area, and at Neung-sa temple site, Wangheung-sa temple site, Geumgang-sa temple site, and Mireuk-sa temple site of Sabi period. They are also observed at Hwanglyong-sa nine-storied wooden pagoda of Shilla and at Biin five-storied stone pagoda of early Goryeo. They are important data improving that the construction technologies of Baekjae continued to be applied to build stone or wooden pagodas, transcending time and space. Recently, the site assumed as a wood pagoda site of Hanseong area was examined in Gyeongdang sect ion of Pungnap mud fortification. If this is proved to be a real wooden pagoda site, this digging-up construction technology of foundation part ann be concluded to be a traditional engineering technology of Baekjae which was frequently used from Hanseong period to Sabi period. On the other hand, this digging-up construction technology of foundation part has been found only at pagoda sites and main building sites of temple ruins, and it helps examine their symbolism.

This study aims to investigate the architectural characteristics of the Da-bo stupa by examining the correlation among architectural languages and by studying the features of its architectural components and transitional changes shown in Da-bo stupa line drawings in Dunhuang Mogao Grottes. The results are as follows. 1st, the Da-bo stupa of Dunhuang faithfully follows the sutra of lotus, and although the form changes, the fundamental essence of Bo-tap-yong-chul and two seated Buddhas provided by the Gyun-bo-tap-pum in the sutra of lotus is consistent. 2nd, the pagoda body can be periodically divided into parasol, stupa, and royal palace types. The parasol type has an incomplete tower body, which makes distinguishing each of its architectural components difficult. The stupa type appeared between the early (AD 618-712) and middle (AD 766-835) Tang dynasty. It combines the form of Indian stupa type and East Asian wood structural architecture. The royal palace type, which appeared between the peak period of the Tang (713-765) and Sung Dynasties, shows the standardized pattern of the Da-bo stupa described as two seated Buddhas and Bo-tap-yong-chul. 3rd, the use of a stylobate does not appear in the early construction of Da-bo stupa, only in the later period, in the form of high pillars. Forms include many Su-mi-jwah and three-way stairways and Dab-do, but as time passes, the forms are simplified to the form of high pillars. 4th, the purpose of early Da-bo stupa was to provide space for Da-bo-yu-rae of Gyun-bo-tap-pum; hence, it did not have sangryoon(the top part). However, after it was influenced by general pagodas, sangryoon was established. Toward the Tang Dynasty, sangryoon has come to emphasize the forms of boryoon(nine wheels) or dome. However, this form is eventually simplified to only retain bo-joo(the orb).

After the great King Munmu constructed Donggung-palace and Wolji-pond in 674, original landscape could not be estimated due to lack of related materials for some 1,250 years until it was surveyed in 1922. Accordingly, the study, to estimate changes of Wolji-pond landscape more accurately, analyzed the study of Hara(1932) and pictures in the Japanese ruling period etc. - these had not been studied so far. The study results are as follows. As a result of comparing survey maps of 1922 and one of 1975, it was found that during 53 years, whole area excluding island showed eroded part by 2~4m, severely, there was mounding area which was lowered by 10m. And it was identified through survey map of 1922 and pictures of the 1950's that inside southern shore protection of the No. 1 construction site were many landscape-stones(景石) which can make imagine a hill; here was water path. Trace of such path etc. remained just before excavation. 2) The construction site No. 3 and 5 in peak shape were higher than construction site No. 1, 2, and 4. Accordingly, there is high possibility that construction stood on high stylobate. So it is wrong that construction site No. 3 and 5 are restored in same height as other construction sites. Comprehensive restoration basic plan made in 2012 was also wrong. As a result of estimating changes of landscape through pictures before excavation of Wolji-pond, the author could identify changes of landscape in mound area and pumice stones which showed much changes in drawing. The study has limit due to lack of space. But if more pictures can be analyzed, it could further help for estimating original landscape of Wolji-pond.

The Octagonal nine storied pagoda of Woljeongsa Temple consists mainly of granite with the rockforming minerals quartz, plagioclase, microcline, and biotite. The surface of the stone stupa is light brown that has been discolored by the rust from the metal ornament and aids. The surface of the stylobate and roof stone is colonized by biological contaminants. Therefore, a comprehensive deterioration diagnosis was carried out in this study, and conservation treatment was conducted. It was proven that the $Fe^{2+}$ yield increases depending on the count of poultice used with oxalic acid, but the $Mg^{2+}$, $Al^{3+}$, and $Ca^{2+}$ yields were marginal following the preliminary test. Therefore, the use of poultice is an effective way of removing the rust, and only marginally influences the rock. The biological contaminants were removed through dry cleaning, and the soil located under the contaminants was removed through wet cleaning. Based on this, the dry and wet cleaning of all the biological contaminants, and the use of poultice with oxalic acid, were done to remove the rust. For the conservation treatment of the metal ornament, the rust was removed through physical cleaning, and anticorrosion treatment was performed on the iron ornament using Renaissance wax and copper ornament by BTA.

The Stupa of State Preceptor Jigwang from Beopcheonsa Temple Site in Wonju (National Treasure) is a representative stupa of the Goryeo Dynasty, with outstanding Buddhist carvings and splendid patterns, clearly indicating its honoree and year of construction. However, it was destroyed by bombing during the Korean War (1950-1953) and repaired and restored with cement and reinforcing bars in 1957. The surface condition of the original stone shows long-term deterioration due to the m ortar used in past restorations. In order to identify the exact causes of deterioration, the m ortar and surface contaminants on the original stone were analyzed. Portlandite, calcite, ettringite, and gypsum from the mortar were identified, and its ongoing deterioration was observed through pH measurements and the neutralization reaction test. Analysis of surface contaminants identified calcite and gypsum, both poorly water-soluble substances, and their growth in volume among rock-forming minerals was observed by microscopy. Based on those results, semi-quantitative analysis of Ca and S contents significantly influencing the formation of salt crystals was conducted using P-XRF to analyze the basis of surface deterioration, and cross-validation was performed by comparing the body stone affected by the mortar and the upper stylobate stone unaffected by the mortar. Results indicate that the elements are directly involved in the surface deterioration of the body stone.

Pan-jang(板墻) has become the lost facility, and the examples of its original form can be found no more due to its variable material characteristics. In order to study panjang as a lost facility, the following are needed: - To bring to light its usage and examples. - To investigate its components and structure. Panjang refers to the wall made of wooden plate and is classified as a special wall according to its material characteristics. In addition, Chinese mokyeongbyuk(木影壁) and Japanese panbyeong(板?) are similar to Korean panjang in terms of the materials, but there are clear differences in their structures. Panjang was also transformed into various types according to their materials or forms. As the wooden elements of panjang, sinbang(信防), pillars, do-ri(道里), jungbang(中枋), inbang(引枋), parn(板), dae(帶), choyeop(草葉), bangyeon(方椽), gaeparn(蓋板), pyeonggodae(平高臺), and yeonharm(椽檻) were selectively used, and they are similar, in particular, to the components of ilgakmoon(一角門). The stylobate of panjang is largely classified into three according to the kinds and structures of the wooden elements; and its frame into two according to whether sanginbang(上引枋) is used or not. The materials for the roof area include planks(蓋板) and tiles and have the distinct structural differences according to each material.

This study was conducted to provide useful basic data for restoration and maintenance of the Changdeokgung Palace(昌德宮)'s inner palace area in the future by exploring the background of terraced flower beds installed in the front space of Seunghwaru(承華樓) and grasping the reality before and after terraced flower beds were installed. The main results of this study can be summarized as follows. First, in the early 1900s, the front space of Seunghwaru formed a relatively higher terrain than the Nakseonjae(樂善齋) area. In addition, along the topography of high north and low south, a yard surrounded by Haenggak(行閣) and a rectangular open space connected to the West Haenggak of Nakseonjae were created. In particular, the rectangular open space was a staircase-type slope in which rectangular stone columns were arranged at regular intervals. Second, the terraced flower beds of Seunghwaru originated from the renovation of the new building of Nakseonjae West Hanggak, which was implemented in the late 1920s. This is because in order to secure enough available land for construction and auxiliary space during the renovation of the new building, the terraced flower beds for topographic treatment was created along the cutting area after cutting off the original topography of the front space of Seunghwaru. Third, after the construction of the terraced flower beds, many deformation occurred in the topographic features of the front space of Seunghwaru. The front yard of Seunghwaru was relatively higher than the Nakseonjae area, but most of them were cut off and disappeared as the terraced flower beds were created. The staircase-type also disappeared after the construction of the new building and terraced flower beds. The stylobate and front fence of Seunghwaru were newly built along the alignment of terraced flower beds and the unique style of narrow gate and auxiliary stairs were also relocated to the new fence.
