A collective theory is tried in analysis on the architectural history of Temple Gowoon in Gyongbook Province. For this purpose, firstly, the chronicle of construction was composed based on the critical study of the old documents. Secondly, the drawings of existing facilities were made after the field survey. And lastly, the collective theory was be able to extracted from the relation between chronicle and physical composion of the Temple Gowoon. The whole temple is composed of two territories, northern one and southern, which are divided by the central ravine. Northern territory was enlarged from Gukrakgeon's cluster through Myongboogeon's to Yeonsoogeon's. On the other hand, southern territory was reduced its position and its size from Daewoongeon's cluster, which was one of the main cluster, to Monigeon's, sub one. These processes were the results of the architectural adjustment, that is say, the dogmatic principles adapted in the topographical environments. The collective forms of clusters are different from each other. Gukrakgeon's cluster is composed of four buildings which enclose the empty inner court. Monigeon's is similar to the small temple type, Myongboogeon's selects the straggling form, and Yoensoogeon's has the type of Confucian shrine. The various types of clusters were the physical settings to symbolize the religious heirarchy of their buildigs. In the front of temple area, Gawoonloo, which located on the ravine and has a big volume, integrates straggling clusters.

비가역성 소자인 광대역 마이크로스트립 Y형 써어클레이티는 Bosma의 Green함수를 적용하여 Rosenbaum이 해석하띠 산란행렬로 실제적 이론치인 삽입손실, 아이솔궤이션을 구하였다. 중요한 설계 변수로는 전봉선과 접합각인 ${\psi}$이고 이를 알맞게 선택하여 광대역 정합을 이루었다. 또한 Y형 써어쿨레이터의 입력칟지던스를 구하였다. 제작시 실표반학은 이론치보다 7.5% 적은것을 요하며 5-11GHz에서 V.S.W.R.은 1.5이하였고 최대 삽입손집은 0.5dB, 아이슬레이션은 15dB 이상이었다. Broadband operation of Y-junction microstrip circulator withlnonreciprocal device is predicteg by Rosenbaum using Bosma's Green function analysis. The anslysis has been modified to enable the scattering matrix and therefore the circulator bandwidth, to be found. The width of the coupling transmission lines is found to be a significant design parameter${\psi}$. A comparison of experimental and theoretical results for the 3-port junction shows that wide lines and a smaller 7.5U than usual disk radius can be used to obtain broadband operation. Circulator operates in the frequency band 5-11 GHz. The obtained maximum insertion loss is 0.5dB and the isolation is more than 15dB.
