In the ancient Buddhist temple area, various metal artifacts are still excavated. Therefore, the aim of this study is to approach the characteristics of ancient architecture through ancient metal artifacts. First, metal decoration of ancient architecture appears for the purpose of structure, decoration, arson. Then, as the method of wood structure is developed, the application is separated into structural, functional and decorative purposes. In ancient times, metal decoration has reduced the role of structure, but its decorative role has expanded. Second, various metallic ornaments were used on the roof of ancient architecture. As the wooden technology developed, the metal decoration was gradually omitted while applying the curve to the roof. Third, the metal ornaments used on the roof of ancient architectures include the ridge central decoration, roof top decoration, a nine-ring decoration, gable board Ornamental Metal, corner flower decoration, eaves nail, wind bell. And subsequent research requires a terminology that can link the results of archeology and Buddhist art through excavation as a result of architecture.

This study was conducted to find proper structural reinforcement methods for the 4.5m-high (eaves height) 1-2W type plastic greenhouse. 3D finite element analysis was used to analyze the steel-tube structure. The 4.5m-high 1-2W type plastic greenhouse was modified by welding 1.5m-long steel-pipes into a 3.0m-tall columns of the standard 1-2W type plastic greenhouse. This remodeling method is widely used in Korea with farmer's discretion to increase the production when they grow paprika. But it is not based on the quantitative structural analysis. The proposed reinforcement methods were proved to stand against the design wind velocity of $40m{\cdot}s^{-1}$ and snow depth of 40cm. It strongly implies that the cross beam between side columns and wind resistance walls, and the lattice type cross beam should be good reinforcements to improve the structural safety of the elevated eaves height plastic greenhouse.

The shape of the roof is very important, as it determines the beauty of the exterior of Korean wooden architecture. In particular, the curve of the eaves is the most representative of the characteristics of Korean wooden architecture. Rafters and buyeon (浮椽), flying rafters, create curves for the eaves, and buyeon in particular makes the roof lighter and more dynamic. Although the function and role of buyeon are already known, nothing is yet clear about the beginning of its use in Korean ancient architecture. Accordingly, the purpose of this study is to determine when buyeon was first used in Korean architecture. To this end, I examined various records, buildings, remains, and artifacts that have architectural shapes in Korea, China, and Japan. The results are summarized as follows. First, the use of buyeon in China appears during the Northern Qi Dynasty (北齊) in the mid-6th century, but became common in the 7th century during the Tang (唐) Dynasty. Second, the use buyeon in Japan appears in the mid-8th century, when the capital was relocated from Asuka (飛鳥) to Nara (奈良). It corresponds with the time that Japan began importing Chinese culture directly. Third, the use of buyeon in Korea may have been introduced to Baekje from China in the mid-6th century, but it was not common. It is believed that it became common after active exchanges with the Tang Dynasty during the Unified Silla Period in the mid-7th century.

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 objective of this study is to find out the recent trends of hanok design based on 58 hanoks appeared in architecture magazines in the last 10 years. The cases are analyzed in terms of location, size, building form, spatial organization, material, roof form, and the ceiling form of living room. The consequences of this study is as follows; Most of the recent hanoks are built in rural area (91.4%), which shows the hanok is not accepted as an urban house type. Hanoks tend to be built in 2 stories whose 2nd floor is smaller than the 1st floor. (34.5%) The preferred size is total floor area of $99.2{\sim}165.2m^2$ (62.0%), 3 rooms (46.6%) with a traditional ondol room (60.3%). The buildings with ㄱ-shape (43.1%) and linear-shape (27.6%) are preferred, and the compact plan type similar with apartment house appears (13.8%). In the roof design that greatly influences the appearance of building, the traditional design factors such as half-hipped roof (55.2%), double eaves (27.6%), and eaves curve tend to be sustained. In terms of spatial organization, most of recent hanoks have double-layed plan (74.2%). The living room mostly has separately defined space. (82.8%) The indoor and outdoor tend to be connected by a narrow wooden veranda (39.7%), while some cases don't have any wooden floor space (48.3%). The entrance is adopted as an important spatial element in front part of building (75.9%), and it influences the appearance of building. The living room, the counterpart of the wooden floor hall in traditional hanok, and kitchen tend to be interiorized. In terms of material, the cement roof tile and red clay brick are preferred. Consequently, the walls of recent hanoks have the image of brick structure rather than the wooden frame structure of traditonal hanok.

It is difficult to build a hipped and gable roof in slender rectangular type due to restraint in variation of lateral length caused by gongpo arranged on the side, purlin space and the form of gable part and aesthetical effect of chunyeo maru. Against this backdrop and with the assumption that this phenomenon is more apparent in roofs of three-bay-kan Buddhist temples with the hipped and gable roof among national treasure Buddhist temples, this study has aimed to prove that a roof can be built in a less slender rectangular type than that of flat form and to present the building methodology and found the following findings. First, The ratio of lateral to longitudinal length of the roof has been adjusted by protruding the chunyeo and the method of adjusting the ratio of lateral to longitudinal length of the roof is considered to be determined depending on the availability of woods to be used in chunyeo. Second, in order to symmetrically arrange the edge of the roof, which is critical from the perspective of construction morphology, the chunyeo angle has been intentionally adjusted to reduce the gap of length between the front roof and the lateral roof. To sum up, the characteristic of the hipped and gable roof, which is difficult to be built in slender rectangular type, is more clearly shown in the roof and it is identified that the length of the front roof and the lateral roof has been intentionally adjusted to achieve the symmetrical arrangement of roofline of the roof edge.

The aim of this study is to analyze the daylight performance at Changdeokgung Nakseonjae that is the representative and most well preserved Korean royal palace. As a result of measuring illuminance and luminance, direct sunlight is cut off by the eaves and reflective light from the court yard comes in the inside of the floor. As the layer of window is increased, daylight is decreased and the illuminance distribution is more stable because of decreasing of illuminance changes. Also, the lower part luminance is higher than upper part of window surface because direct sunlight is cut off by the eaves. This study would be used as preliminary data for applying characteristics of lighting environment of Korean royal palace to modem architecture.

HyangGyo had been built for teaching peoples as a place of educational practice, and also for the order and stability of country through Confucianism. This study analyzed and researched the building structure of Daejeong-HyangGyo in Jeju Island In Daejeong-HyangGyo, unique architectural characteristics are shown as they have been built in an island independent from the mainland. Also up-down system was well reflected in detailed architectural styles. The main temple of Daejeong-HyangGyo was built in the type of one-Chulmok(a subsidiary material of Gongpo and a piece of wood to support the eaves) of which ancon supports a purline from the center of a pillar and two-Ikgong(a piece of wood engraved to put on an ancon), but in the case of the lecture hall, its Gongpo(a piece of wood to support the eaves) was inferior in quality. In the case of Jeju abutments were used in main temples and fire walls were mostly used. In particular, their abutments are difficult to be observed in HyangGyo in the mainland. It is presumed that the abutment and the fire wall used in Jeju Island might be the best solution to protect structures from rain and moisture. To sum up, local characteristics and traditional rules were thoroughly reflected in Dajeong-HyangGyos built in Jeju Island from the aspect of arrangement and detailed style. In conclusion, it is significant that architectural styles, not to mention the other aspects of Jeju culture, were suitably adapted to Jeju Island.

Since 'Hanok Expanse Support' has been started in Seoul, its target was expanded from renovation to new construction and from 'Hanok District' to all area in Seoul. The newly built hanok with Hanok Expanse Support had to follow the standards about the form of the hanok and adapt to modern lifestyle. However, the newly built hanok were planned with 'kan' since it retained the traditional wooden structure. So their composition of kan were considered to be influenced by the standards of each district and modern lifestyle. Therefore the aim of this study is to understand the architectural characteristics of newly built hanok in Seoul since 2000 focusing on the kan composition. Because of the differences in site conditions and the district unit plan, newly built hanok in Hanok District have more limited changes than Other District. However, kan is composed variously in horizontal and vertical ways to make the most space according to site conditions and most of the newly built hanok have opened courtyard rather than closed courtyard layout. With kan composition in various directions and kan added under the eaves, kan is highlighted in form. On the other hand, the composition of kan as an interior spatial element has changed and weakened because the lifestyle has changed compared to the traditional hanok and the 20th century urban hanok. Also the regular kan composition of Mom-chae and Nalgae-chae has changed. And kan is divided regardless to the wooden structure. Also, with the added kan under the eaves the main kan is dismantled inside. This paper indicates that although there is an undeniable premise that the case is restricted to hanok received Hanok Expanse Support on the condition of following the standards of the form of hanok, it is a part of the transitional changes that hanok is experiencing.

This study is designed to find out the role and relation of the Nemok-dori support members in order to clearly specify the structure of the Dapogye architecture which adopts the Nemok-dori. The dori at the eaves in the Dapogye architecture was expanded to include Oemok-dori, Jusim-dori and Nemok-dori in cooperation with the bracket. The Oemok-dori is used to lengthen the eaves and the Jusim-dori makes the reasonable transfer of loads while the Namok-dori contributes to the stability of the building through the balancing of the bracket. Nemok-dori is located higher than Oemok-dori or Jusim-dori, depending on the slope of Jangyeon and the distance of Chulmok. But as it is not directly supported by bracket or beam, it needs an independent support. The vertical support of Nemok-dori is selectively involved with Cheomcha, lower Jangyeo, support Wall and upper Jangyeo. As the time went by, the vertical height increased, thus making the omitted members less. The horizontal support of Nemok-dori is made in various ways. There are also special cases such as the Nemok-dori □ type chain structure for small rectangular buildings, the 'Nemok-dori = Jung-dori' type for the buildings having small sides and the 'Nemok-dori = Meongechangbang' type appearing on the lower part of the Bankanmulrim type middle height buildings. The horizontal support of Nemok-dori usually uses either the support of the Toeryang type member, the support of beam directed Hwaban or the support through overlaying of internal Jegong. As the time went by and the number and distance of Chulmok increased, the multiple support structures acted together rather than as one support structure. Nemok-dori got stabilized as it has both the vertical and horizontal supports and this support structure also has he role of decoration.
