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.

전통 목구조 건축물은 크고 작은 부재가 많이 결구되어 있기 때문에 구조해석을 위한 모델링에 어려움이 있다. 기존에 제안된 모델링 기법은 모델링과 해석에 많은 시간이 필요하기 때문에 이를 개선할 수 있는 효율적인 방법이 필요하다. 본 연구에서는 전통 목구조 건축물 중 가장 많은 부재로 구성된 공포의 거동을 구현할 수 있으며 모델링과 해석에 소용되는 시간을 줄일 수 있는 모델링 기법을 제안하였다. 제안된 모델의 적합성을 확인하기 위하여 다양한 하중 재하 형태에 대한 유한요소 모델의 응답과 비교하였다. 해석결과에 따르면 제안된 모델의 응답은 유한요소해석결과와 10% 이내의 오차범위 안에 있어 공포의 해석시 보다 간편하게 활용할 수 있을 것이다.

This study is about the meaning of wooden brackets that are distinctive elements of wooden architecture in Korea, Japan, and China. Existing studies about wooden brackets have been limited to the boundary of formalism, so the object of this study is to make a breakthrough in the field of those studies. The Wooden brackets in this study are considered to be decorative elements, and the principles of their design are examined. The specific subject of the study is wooden architecture with Jusimpo-styled brackets that have brackets only on pillars. The definition of Jusimpo is reexamined first, and ChulMok-Ikkong which has not been regarded as a Jusimpo-styled wooden bracket is interpreted as Jusimpo-styled one in this study. Categorized into three types, Jusimpo is examined how it is expressed according to the type of the roof in a building. In view of the results, the wooden bracket system is an effective technique to express the formality, and two designing principles can be seen in Jusimpo; one that wooden brackets observed externally are standardized and regarded as the same ones, and the other that the style of wooden brackets used in the most formal building is Yi-ChulMok. These designing principles mean that the carpenter who was in charge of building the architecture had certain principles when expressing wooden brackets as well as the roofs according to the class of the architecture. In addition, although the styles of wooden brackets that were used in the most formal architecture during the Chosun period were mostly Dapo, Jusimpo in the form of Yi-ChulMok was also adopted in some temples depending on their scale, and that means Jusimpo-styled wooden brackets were never considered to be inferior to Dapo-styled ones. And this point leaves the argument that the reexamination of Jusimpo-styled wooden brackets which have been regarded as the style used in the attached building or small structures since the Choun dynasty should be conducted.

The purpose of this study is to find framework schema of early J usimpo-style Buddhist halls (Geungnakjeon Hall of Bongjeongsa Temple, Muryangsujeon Hall of Buseoksa Temple, and Daeungjeon Hall of Sudeoksa Temple). Though the halls are known as built in the late Goryeo Period, they show the influence of the architectural style of the early Unified Silla Period. To find the adopted modules and proportions of these halls, this study conceived a schematic diagram based on the whole frame structure taking reference from the Cai-Fen system in Yingzao Fashi. In these three halls, the heights of each cross-beam (Dori) are made up by the layers of member and member units. This study computes the values of Cai, Zhi, and Fen which can apply to both the section and the plan. The vertical section structure is determined by combining the standard member heights (Cai) and the standard unit heights (CaiZhi). The bays of columns are made by multiples of the standard member width (Fen).

현호색속 6종의 대배우자체 발달과정이 공초점현미경(LSCM)과 광학현미경으로 비교, 관찰되었다; 흰현호색, 왜현호색, 섬현호색, Corydalis nobilis, C. solida, C. ophiocarpa. 포원세포는 돌출된 주심조직의 단층 표피 밑에 존재하는 측벽세포의 최외곽층 세포들에서 하나가 기원하였으며, 직접 대포자모세포로서 작용하였다. 대포자모세포는 대포자발생과정을 통하여 연속적으로 2회 분열한 후 선상의 4분체가 되었으며, 이들 중 주공쪽의 3개는 퇴화하고 합점쪽의 1개만이 기능성 대포자로 발달하였다. 자성배우자체의 발달 유형은 단포자성, 마디풀형(Polygonum type)이었다. 개화 전 자성배우자체는 성숙하였고, 따라서 성숙된 배낭은 3개의 세포로 이루어진 난장치, 거대한 핵이 있는 3개의 대형 반족세포 및 2차핵이 존재하는 1개의 중앙세포로 구성되어 있었다. 반족세포 흡기는 반족세포의 정단에서부터 각각 발달되었으며, 주공쪽으로 신장되어 난장치와 접촉하였다. 2개의 조세포는 보통 퇴화된 상태로 관찰되었으며, 이때 반족세포 흡기의 정단은 퇴화된 조세포와 연결되었다. 7-세포성 자성배우자체의 발달과정상 특징은 조사된 모든 종에서 공통적이었으나, 배낭의 형태는 흰현호색, 섬현호색, C. solida 및 C. ophiocarpa에서는 난형이었으며, 왜현호색에서는 반곡형인 반면 C. nobilis에서는 다소 납작한 난형이었다. 또한 대포자낭의 유형은 모든 종에서 도생배주였으나 왜현호색에서는 만곡배주였다.
