The purpose of this study is to find framework schema of early Jusimpo-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).

The results of analyzing opening types in the rear elevations of ninety-six buddhist temples which would be existence can be summarized as follows ; 1) Opening types in the rear elevations of buddhist temples in the Koryo Dynasty were various as the type of doors and windows, and the type of combining with walls. but the fact had something in common that whole door was the swinging pannel one, and the type of the whole window was the lattice and the mullioned casement one. 2) The type of the lattice windows were disappered and the only type of the mullioned casement windows were put in an apperance in the early period of Cho-sun Dynasty. 3) The type of doors + walls and the type of doors + windows in the rear elevations of buddhist temples of the seventeenth century were absolute. Especially the mullioned casement windows were used mainly in buddhist temple of the type of doors + windows. 4) The type of doors + windows in the rear elevations of buddhist temples of the eighteenth century did not be seen, but types of doors + walls and walls + walls which were much enclosed, were mainly put to use in those.
