A seismic intensity map, which describes ground motion distribution due to an earthquake, is crucial for disaster evaluation after the event. The ShakeMap system, developed and disseminated by the USGS, is widely used to generate intensity maps in many countries. The system utilizes a semi-variogram model to interpolate the measured intensities at seismic stations spatially. However, the default semi-variogram model embedded in ShakeMap is based on data from high seismic regions, which may not be suitable for the Korean Peninsula, categorized as a low-to-moderate seismic region. To address this discrepancy, this study aims to develop the region-specific semi-variogram model using local records and a region-specific ground motion model (GMM). To achieve this, we followed these steps: 1) collected records from significant earthquake events in South Korea, 2) calculated residuals between the observed intensities and predictions by the GMM, and 3) created semi-variogram models using weighted least squares regression to better fit short separation distances for PGA, PGV, SA0.2, and SA1.0. We compared the developed semi-variogram models with conventional models embedded in ShakeMap. Validation tests showed that the region-specific semi-variogram model reduced the mean squared error of intensity predictions by approximately 3.5% compared to the conventional model.

The object of this research is to examine the planning principles of Sangju which has an old history The results of the investigation are as follow 1. Sangju placed on the plains in the castle, it is established in Korea Dynasty 2. The formation of Sangju is infruenced Feng-shui. They plants Chestnuts against centipede mountain 3. Sangju is similar to the configuration of the another city in Feng-shui and elements of Component. But, many buildings(jin-Young(Military site), Choong-Ui-Dan, Choong-Yeol-Sa) are associated with the war in Sangju. 4. The City hall is located on the west side of the hotel(Kaek-Sa). It is located on Wang-San which is a place where citizens with symbolism. So, the City hall is higher than Kaek-Sa 5. The cruciform style road which connected with 4 gates was formed in the castle.

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.
