This paper is about Zhuzi(朱子) writings entitled Yixueqimeng("易學啓蒙"). There are only four research articles on Yixueqimeng("易學啓蒙"), although it had taken important role in the process of formation of Zhuzi(朱子) study of changes, comparing with 30 different kinds of research on his works after this Yixueqimeng("易學啓蒙"). In line with this, the author intends to make this paper as a full-scale research article on Zhuzi(朱子) work - Yixueqimeng("易學啓蒙"). Zhuzi(朱子) exposes the meaning of the Xiangshuyixue(象數易學), to wit, the emblem and numerology of Emblem and Numerology in interpreting Zhouyi("周易") again by accepting Hetu("河圖") and Luoshu("洛書"). When discussing the Zhouyi("周易"), Yiliyixue(義理易學) had drawn supports from Wangbi(王弼) Deyiwangxianglun(得意忘象論). Likewise, Zhuzi(朱子) tried to ruminate upon the meaning of the Hetu("河圖") and Luoshu("洛書") through the Yixueqimeng("易學啓蒙"). As he interprets all things through Hetu("河圖") and Luoshu("洛書"), these two systems of emblem have become essential. Even in Shifa(筮法), he elicited Dayanzhishu(大衍之數) from Hetu("河圖") and Luoshu("洛書") so that he related the divination rule to Hetu("河圖") and Luoshu("洛書"). By doing so, Zhuzi(朱子) concatenates Dayanzhishu(大衍之數) to Hetu("河圖") and Luoshu("洛書") too. Furthermore, by interpreting Yongjiu(用九) and Yongliu(用六), which belong to Qiangua(乾卦) and Kungua(坤卦) as prognostication that will be referred to when all six-line symbols are changed, he had made a great contribution to the history of Zhouyi("周易") study. Zhuzi(朱子) is responsible for a sizable part of the history of Zhouyi("周易") study as much as Wangbi(王弼) and Chengyi(程?). Of course, there are some parts where efforts were made in vain, however, the method to interpret the Zhouyi("周易") have developed day by day owing to the efforts of Zhuzi(朱子).

In order to establish a balanced development plan at the local government level, it is necessary to understand the current urban spatial structure. In particular, since the central area is a key element of balanced development, it is necessary to accurately identify its location and size. Therefore, the purpose of this study was to identify the central area system for Busan and to derive underprivileged areas that were alienated from the service areas where the functions of the central area could be used. To identify the central area system, four indicators(De facto Population, Land Price, Commercial Buildings, Credit Card Consumption) were used to calculate the central area index, and Getis-Ord Gi* and DBSCAN analysis were performed. Next, the hierarchy of the central areas were classified and the service areas were derived through network analysis by using it. As a result of the analysis, a total of 12 central areas were found in Seomyeon, Jungang, Yeonsan, Jangsan, Haeundae, Deokcheon, Dongnae, Daeyeon, Sasang, Pusan National University, Busan Station, and Sajik. Most of the underprivileged areas affected by the central area appeared in the Eastern area of Busan and the Western area of Busan, and were derived from old industrial areas, residential areas, and some new cities. Based on the results of the study, we can find three meanings. First, we have made a new attempt to apply a machine learning methodology that has not been covered in previous studies. Second, our data show the difference between the actual data and the existing planned central areas. Third, we not only found the location of the central areas, but also identified the underprivileged areas.
