Ancient Farm Tools in Japan and Korea -Comparative Study on the History and the Functions-

关于日韩农具史的比较研究还不够深入。这一联合研究项目促成了两国就这一主题举行的4次国际联合研讨会。这些研讨会迈出了第一步，并将进行下一阶段的比较研究和合作。发展的方面; 1）日本与韩国多个地区的历史联系是独立的; 2）与半岛南部地区卡拉的联系应重新评估; 3）济州岛对考虑东海文化区的重要性，特别是在犁、铲和锄头的技术转移方面。这种方法是结合历史研究中的一般研究方法来界定过去农具的有效方法。数值和力学分析弥补了文献证据的不足。利用有限元法对保存在首尔国立中央博物馆的古代犁剪和模板进行了分析，确定了犁削过程中的牵引阻力。在联合研讨会上介绍了这一方法的应用，并讨论了其可用性。

Comparative study on Japanese-Korean history of farm tools has not enough been studied. This joint research program promoted 4 international joint seminars on this topic in both countries. The first step was established by these seminars, and will be proceeded to next stage of comparative researches and collaborations. Evolved aspects were ; 1)the historical connections are independently seen between Japan and plural regions in Korea, 2)especially the connection with Kara, south region of the peninsula, should be reestimated and 3)Cheju Island is important for considering East China Sea cultural region, especially on the technology transfer of plough, spade and hoe.This project is also remarked by the research method of the application of functional analysis on farm tools. This method is effective to define the past farm tools by combining ordinary research method in historical study. Numeric and mechanics ayalysis compensates the lack of documentary evidence. The ancient plough shear and mold board stored in Nation Central Museum of Seoul was analyzed by using finite elemental method to define the drawing resistance in ploughing. The application of this method was presented in joint seminars, and its availability was discussed.
