  • The purpose of this paper is to identify the difference between Sangsan-Simhak(象山心學) and Yangming-Simhak(陽明心學). This means that the whole history of Sung Confucianism needs to be understood based on changing philosophical paradigm according to the times, not general perception which regards the whole history of Sung Confucianism as Li-Hak (理學) and Sim-Hak(心學). This kind of perception is caused by the general perception which divides Sung Confucianism into Sim-Hak and Li-Hak. We regard the former as Chung-Chu study and the latter as Liu-Yang study. Because of this, Sangsan study is recognized as the former stage study of Yangming study and can not be placed in independent position in whole history of Sung Confucianism. And Sang is regarded that it takes diametrical opposition with Chuhsi study. So it is said that there is no point of sameness among them. But Sangsan study was generated from 'Song-Hak(宋學)' based on paradigm of Li-Hak and Yangming study was generated from 'Ming-Hak(明學)' based on paradigm of Sim-Hak. The difference between 'Song-Hak' and 'Ming-Hak' is generated from proposition called 'Sim is Li (心卽理)' that most research has overlooked. To identify these things, this paper examine the philosophical difference between 'Song-Hak' and 'Ming-Hak' and analyze the proposition 'Sim is Li(心卽理)' that regards Sangsan study and Yangming study as same philosophical system. And this paper identify the philosophical difference between Sangsan study and Yangming study by examining the method that the concept of 'Sim is Li(心卽理)' is applied in moral cultivation. This paper shows that the difference of interpretation about the concept of Li(理), between 'Song-Hak' based on Li paradigm and 'Ming-Hak' based on Ki-Hak(氣學) paradigm, causes different meaning in 'Sim is Li(心卽理)'. Through these, this paper demonstrate the difference between the paradigm of 'Song-Hak' that Chuhsi study and Sangsan study have and the paradigm of 'Ming-Hak' that Yangming study has and the fact which Sangsan study is systematic philosophy of Sung Confucianism in itself not former stage of Yangming study.

  • The KaiFangFa開方法 of traditional mathematics was completed in ${\ll}$JiuZhang SuanShu九章算術${\gg}$ originally, and further organized in Song宋 $Yu{\acute{a}}n$元 dinasities. The former is the ShiSuoKaiFangFa釋鎖開方法 using the coefficients of the polynomial expansion, and the latter is the ZengChengKaiFangFa增乘開方法 obtaining the solution only by some mechanical numerical manipulations. ${\ll}$SanHak JeongEui算學正義${\gg}$ basically used the latter and improved the estimate-value array by referring to the written-calculation in ${\ll}$ShuLi JingYun數理精蘊${\gg}$. As a result, ZengChengKaiFangFa was more refined so that the KaiFangFa algorithm is more consistent.

  • This paper is a sequel to the paper [8], where we discussed the connection between ShiShou KaiFangFa originated from JiuZhang SuanShu and ZengCheng KaiFangFa. Investigating KaiFangShu in a Chosun mathemtics book, SanHak JeongEui and ShuLi JingYun, we show that its authors, Nam ByungGil and Lee SangHyuk clearly understood the connection and gave examples to show that the KaiFangShu in the latter is not exact. We also show that Chosun mathematicians were very much selective when they brought in Chinese mathematics.

  • 국부적이지만 수 mm단위까지 스캔이 가능한 지상LiDAR 장비를 이용하여 사면을 스캐닝한 후에 사면의 6개 지점에 대하여 강제로 변화를 준 후 다시 스캐닝하여 분석한 결과 0.008m의 평균편차를 나타내었다. 이것을 볼 때 미세변화 탐지를 위한 기법으로 지상 LiDAR자료의 적용이 유효할 것으로 판단된다.
