In Korean traditional architecture, the Gong-po style is divided into the Jusimpo, Dapo and Ikgong. Jusimpo and Chulmok-Ikong, where only Gong-po is placed on the column, differ in form of Gong-po depending on the viewpoint. Since 'Chulmok-Ikgong' has been generally regarded as 'One Chulmok-Two Ikgong', the precedent researches have been conducted mainly on 'One Chulmok-Two Ikgong' in the Gong-po style classification. However, when it comes to 'One Chulmok', the style of Ikgong can be organized from the one to three steps and this study is particularly for examining the occurrence and transformation of 'One Chulmok-One Ikgong'. One of the case study sites, Bonghwa Cheongamjeong was originally built in the 16th century, and is believed to have been repaired from 'Non Chulmok-One Ikgong' to 'One Chulmok-One Ikgong'. Since the beam linked directly to the upper part of a capital, it does not connect the eave trave(architrave) in between. Also, Soro which supports Jangyeo(the architrave strip) has been placed and linked in comparatively lower position. It is confirmed by the signigicant difference in the hierarchy of Gong-po forms in one architecture. The Jeonju-Hyanggyo Daeseongjeon, which was built in the 17th century among the subjects, was similar with 'One Chulmok-One Ikgong', but it was found to be the type of Jusimpo form because the bottom of the beam and the top of the Ikong are apart. And Gongan is confirmed at Cheomcha. In the 17th century, it can be seen that Heot-Cheomcha disappeared and Ikgong was started to use as a constant figure. The end of the 18th century, it can be seen that it was changed into a ornament added on Haeng-gong, being seen in the case of Hwaseong Dongjangdae. In conclusion, it can be seen that 'One Chulmok-One Ikgong' were developed in both the Jusimpo and Ikong style. The transformation into 'One Chulmok-One Ikgong' was inevitable consequence related with an elevation difference between the eave trave and the column trave.

There were lots of changes of the wooden structure in the middle of Joseon Dynasty. It was the time of replacement from Jusimpo (simple bracket system) to Ikgong (wing-like bracket system) and each bracket had shown mutual variation as well as itself. The aspects of change were discovered that the decorative elements of Ikgong and Dapo (multi-bracket system) had accepted from each other. It was clearly shown that not only the Ungung (carved cloud-shape) and Chotgaji (shape of the acuminate leaf) of Ikgong had affected to Dapo, but also Gaang (pseudo-pointing cantilever) of Dapo had affected to Ikgong. It was mostly found in the Buddhist architecture because there was the conservatization of ruling hierarchy as well as the active growth of Buddhist society.

The purpose of this study is to comprehend strengthening Hwaban(flower-shaped support) design in the Two-lkgong style government buildings in the late Joseon period through the T-shaped wooden shrines, the architectures of royal palace and royal ancestral shrine. Following conclusions have been reached through the study. First, Janghwaban(the long plate carved with flower-shaped support) was installed in Injeongjeon(1805) for the first time. It took 40 years to introduce Janghwaban to the government building of Two-lkgong style compared with Injeongjeon. Second, the quantity of Hwaban had been increased from 1 to 5 for 300 years in the government building of Two-lkgong style. This had been steadily increased with the aim of strengthening design. Third, there was a limit to the increase in the quantity of Hwaban. The first reason was to control the rhythm between the Hwaban and the Pobyeok(the wall between Hwabans). The second reason was that if the Pobyeok was too narrow, it was difficult to plaster. The latter was solved by introducing the Janghwaban. Fourth, in attempting to stylize differently from Jusimpo(simple bracket system), the quantity of Hwaban increase played a very important role in the government building of the Two-lkgong style. Since the reconstruction of Gyeongbokgung Palace, Hwaban combined style with Ungong served as the norm of the royal palace architecture in the last Joseon period.

Jukseoru is a pavilion building located in 44 Jukseoru-gil, Samcheok-si, Gangwon-do. Jukseoru is characterized by the fact that the center 5 bays out of the front 7 bays are in the form of Jusimpo, while the ends of each side are in the form of an Ikgong. In addition, the columns are not aligned with each other because the columns of both compartments are out of the center rather than the columns of the center of the five compartments of the columns do not match each other. Based on this, architectural historical circles initially built five bays in pairs, but later added one space to each side to make it seven bays. Recently, however, a new claim has been made that it was built with seven bays from the beginning. Therefore, this paper proved that Jukseoru were expanded through historical data. We also looked at the characteristics of the Jukseoru period and the process of transformation through comparison of the bracket type.

Thirty-five of Hwaban of Jeongjagak had been built in the last three hundred years, which means a Hwaban was made in almost every ten years. Jeongjagak is a building that requires a certain ornamentation having the identical Gongpo type, called E-ikgong, and maintains the same shape for a long time. While Hwaban is an element that faithfully serves the ornamental role, the field study found that Hwaban-chogak went through various changes over the years unlikely to Jeongjagak. This study enumerates and classifies the various types of Hwaban-chgak by outlining the similarities/differences of the various types of Hwavanchogak, and by discovering what the craftsmen aimed to express through the Hwaban-chogaks. As a result, Hwaban-chogak can be generally divided into two categories depending on the starting point of Chogak: 'Downward-Type' and 'Upward-type' and the study tried to find the origin of that. The first represents the stems of Hwaban crafts flowing from top to bottom, and the latter showing the opposite direction. Around 1740s Upward-type can be chronologically caragorised as; 'original- type' which contains lotus and 'modified- type' which eliminates lotus. It is inferred that the modified-type was caused by the employment system of the craftsmen. It is also recognized that the main frame of Hwaban-chogak had been maintained despite the fact that Chogak became increasingly ornamental for the next a hundred years from the Hwaban-chogak drawings in Whaseong-seongyeog-uigwe, which was completed in 1796. The study has a limitation that the focus of the research is only on the Hwaban of Jeongjagak and expected to look into Hwaban in the context of other construction elements such as Ikgong, Daegong and Anchogong for further studies.

This study was performed to ascertain how HyangGyos based on national ideology were built in Jeju Island and what their detailed styles are. In Jeju-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 Jeju-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 Jeju-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.

This research aimed to suggest a standard design that reflects Hanok design tendency, and present a selective design that can fulfill a building owner's intention beyond the simple function of building permit or report. In addition, this research attempted to become a standard by establishing a criterion in calculating the measurements of section design or primary framework members, in order to be a guideline for designing Hanok in different sizes and forms. The results are as follows. The building area of Hanok standard design was set to be below $85m^2$, with a straight type of $83.16m^2$ and an L-shape of $84.24m^2$. By dividing the plane into a straight type and L-shape, two straight types were suggested: 'general type' and 'large living room type.' The upper floor space, along with the main room and small room, was proposed as an option to be changed into a room where an underfloor heating is installed depending on the building owner's intention. In addition, a criterion for side design and calculation of framework measurements was suggested and applied, while a five-girder design without high pillars was suggested for material-assembling structure. Two types of pillars-circumference and square cylinder-were proposed for the building owner to choose from, and a pointed beam house and ikgong(orthogonally-projected bracket) house were suggested for pojak bracket structure so either of them could be chosen according to the building owner's taste and economic condition. Finally, the sectional size of main materials were divided according to the form of pojak bracket structure to be proposed.

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.

The purpose of this study was to reconsider existing hypotheses on the orinination and changes of changbang-anchogongs and their types and suggest an alternative hypothesis. The earliest changbang-anchogongs in $17^{th}$ century is presumed to originate as imitations of chungbang ppaelmoks for ornamental and reinforcing parts for changbangs. They were framed whole sides of buildings equally, and were used in small numbers of extant royal buildings and Buddhist halls. From late $17^{th}$ century, enlarged dragon shape changbang-anchogongs applied to Buddhist halls maily to decorate and strengthen front side of buildings. As a result of exchange between changbang-anchogongs and Ikgong type brackets, combined changbang-anchogongs in Buddhist halls were invented for stronger connection with upper bracketing units and have been spread during $18^{th}$ century. Danpyeongbang anchogongs were originated by the connection between short pieces of pyeongbangs and early type of anchogongs similar to ppaelmoks. They belong to minority subtype, but were drawn in illustrations by mistake, as parts of main halls of royal palaces from $19^{th}$ century, because of painter's confusion about new techniques for changbang-anchogongs. Combined changbang-anchogongs for royal buildings were presumed to be invented in 1790s by stimulation from a Buddhist hall related to royal tomb. However, unlike Buddhist precedence, they were used to reinforce and decorate whole sides, even corners, of buildings, and their frameworks and shapes were imported from Daeryang-anchogongs at flanks of ritual halls in royal tombs and royal shrines from $17^{th}$ century.
