A study on the structural feature of coffin, compartment protecting coffin, and chamber in the Three Dynastic Period of Korea.

本研究旨在探讨韩国三代墓葬的棺、护棺室和墓室的结构特征，以了解朝鲜三代墓葬的地域特征和变化。结果发现，棺木结构特征的地域性特征在原三朝时期就开始出现，且无论当时墓葬间的结构变化如何，棺木结构特征仍保持在4、5世纪。据我所知，6世纪时，在高句丽、百济、新罗、卡雅等地，这种石棺被改造为国王的主要墓葬设施。

This study project aimed to examine the structural feature of coffin, compartment protecting coffin, and chamber, for finding out the regional characteristics and the change of the tombs in the Three Dynastic Period of Korea. As the result, I revealed that the regional characteristics of the structural feature of coffin began to appear in Proto Three Dynastic Period, and they were maintained still 4th and 5th century, regardless of the structural change among the tombs at that time. And I found that the new style coffin diffused in the territory of the Koguryo, Paekche, Sinla and Kaya in 6th century, when the corridor-style stone chamber was adapted as the main burial facility of the tomb of a king.
