We first used radiocarbon dating, TL/OSL dating and archaeo-magnetic dating to calculate the absolute chronology of various objects excavated from the Gyesil-ri archaeological site at Gongju. After we had summarized the probability density of all absolute chronologies of each object by using the KDE model performed a peak deconvolution with a normal distribution, and found that human activity first occurred at the Gyesil-ri site in 840 $\pm$ 160 AD (1$\sigma$ SD) and continued from 1,250 $\pm$ 160 AD (1$\sigma$ SD) to 1,670 $\pm$ 180 AD (1$\sigma$ SD). Those periods correspond to the Unified Silla, Goryeo dynasty and late Chosun dynasty, respectively. Within the Gyesil-ri site, the objects related to metallic works, including the slag layer in the late Chosun dynasty period were located perpendicular to the contour lines, which means that the metallic works were carried out at higher places in the Gyesil-ri site and that slag, as well as other residuals, were naturally discarded in lower places.
