This article examines Zhu Xi(朱熹)'s theory of I-Qing(易經) present in Yi Xue Qi Meng. Zhu Xi aims to establish a novel Confucian theory of I-Qing, examining the study of I-Qing in Han Dynasity and the Taoist theory of I-Qing. To this end, he embraces Shao Yong(邵雍)'s theory of Xian Tian. Adapting the notion of Xian Tian(先天) as developed by Shao, he completes the Image-Number(象數) Theory of Hetu-Luoshu(河圖洛書). While discussing Hetu Luoshu, Zhu Xi argues that the Image and Number are not merely a form of prognostication, but a medium that reveals the principles of the nature and the sagely ways of mind. In addition, by studing I-Zhuan(易傳) in authoring Yi Xue Qi Meng, Zhu Xi maintains that the notions of Image and Number as he understands were to be approved by Confucius. This leads to the unification of Sho Yong's Tai-Ji(太極), Zou Dun Yi(周 敦頤)'s Tai-Ji, and Tai-Ji in Hetu. Through this work, Zhu Xi attempts to construct a systematic philosophy that straddles ontology and value theory, while identifying Li (理) with Xiang (象) and Shu (數). The Image-Number Theory of Hetu-Luoshu has replaced numerous theories of Image and Number at the time of Zhu Xi. Based on this theory, he restores the method of divination as presented in Xi CI Zhuan(繫辭傳). By successfully applying his theory of Image and Number to interpreting a number of recorded examples of divination during the Spring and Autumn period and the Warring States period, Zhu Xi demonstrates that his theory is not only an abstract metaphysical theory, but also can function as an adaptable method of divination.

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).

This article aims to investigate the studies of Yi Xue Qi Meng(易學啓蒙) performed by the researchers of Neo-Confucianism in Ki Ho region in later Chosun period. Philologically speaking, these studies were mainly performed by Han Won Jin and his colleagues. While the study of Yi Hwang(李滉)'s Qi Meng Zhuan Yi(啓蒙傳疑) performed by the researchers of Toegye(退溪) School lasts from the end of the sixteenth century to the nineteen's century, the Ki Ho(畿湖) scholars' study of Yi Xue Qi Meng are centered in the eighteenth century and hardly any significant work on this text is found before and after this century. In order to single out the distinctive features of Ki Ho School of Neo-Confucianism, this article examines three subjects the Ki Ho scholars delved into: (i) their theory of Tai Ji(太極), (ii) their theory of He-Tu(河圖) and the formation of eight trigrams, and (iii) the so-called Wu Wei Xiang De Shuo(五位相得說) discussed in one of the sections in Yi Xue Qi Meng titled the Source of He-Tu and Luo Shu[本圖書]. The Ki Ho scholars are remarkable in interpreting Tai Ji in Yi Xue Qi Meng in the context of the theory of Li-Qi and the theory of human nature. There are differences in opinion among the Ki-Ho scholars with regard to the relation between He-Tu and the formation of eight trigrams. Eventually, they withhold Zhu Xi(朱熹) and Hu Fang Ping(胡方平)'s attempt to synthesize He-Tu, the rectangular diagram of Fu Xi(伏羲)'s eight trigrams, and the circular diagram of Fu Xi's eight trigrams into one single principle. Han Won Jin tries to explain the relation between He-tu and the formation of eight trigrams in terms of the relation between He-Tu and the circular diagram, and his attempt is widely supported by his colleagues. This theory runs counter to traditional model of explaining truth. My conjecture is that such academic trend is further developed by the defenders of Practical Learning such as Hong Dae Yong(洪大容), who vigorously reject traditional system of truth and science, and that it partly explains why the study of Yi Xue Qi Meng ceases in the nineteenth century.

颐斋在『颐斋乱藁』中记录了自己对周易进行学习的内容.他从1760年(庚辰)32岁开始正式在白羊寺的众多庵堂里进行研读, 历经３年, 于1763年(癸未)7月23日离开白羊寺.之后, 他与金时粲, 徐命膺, 沈定镇, 韩晚裕, 李得显等人一起对周易进行了讨论, 并将自己的见解记录下来.他留下的注释书有 『皇极经世书解』 『朱子明筮赞解』, 『阳九阴六用数图』, 『经世天地始终之数图』, 『经世四象体用之数图』, 『易学啓蒙解』 等. 还有 『读易学啓蒙』, 『论易吟』, 『大易吟』 等３首与周易相关的诗.本论文则通过这３首诗对颐斋的周易特色进行阐明, 其特色大致可以概括为受容, 继承并发展了朱熹的主张.但他对周易的理解, 就像他所说的'通过象和数可以进行更好地理解'那样, 与义理相比, 他更关心象数, 实际上关于象数的注释和讨论也更多.因此, 虽说周易从象数易和义理学方面发展为图书易和儒家易, 并由朱熹完成了象数易和义理易的大统一, 但颐斋可以说则是一位以义理易和儒家易为基础, 十分看重象数易的易学者.

Lee Ik(李瀷) had put emphasis on the achievements by self-regulated academic learning through doubts, and at the same time that it was all-embracing. His academic attitude had set an example among the members of Seongho school(星湖學派), and his disciples had strived to emulate his style. The greatness of Seongho(星湖)'s study had been revealed by development of Seongho school(星湖學派) right after his death. He had argued that the six strokes of I-Ching should be read having it divided into inward and outward divine signs. He had stated his view clearly that the divine signs ranging from one stroke to six strokes were not connected, same as Shao yong(邵雍)'s method, but, the three strokes of inward divine sign as well as the three strokes of outward divine signs were independent from each other. Seongho(星湖) also had raised many questions about Shifa(筮法), and Bianyao(變爻) and Zhuzi(朱子)'s Shifa(筮法), or Yixueqimeng("易學啓蒙") "Kaobianzhan("考變占")". In view of the Shifa(筮法), Seongho(星湖) had helped Dasan(茶山) to present 'Shiguafa(蓍卦法)' by proposing different divination rule from Zhuzi(朱子)'s Method of Divination by Shiyi("筮儀"). Seongho(星湖) had not professed something significantly different from Zhuzi(朱子) in his I-xue. His study on I-xue had been accomplished under his goal of achievements by self-regulated academic learning through doubts. "Shiguakao("蓍卦攷")" is also same. I-xue of Seongho(星湖) had made a great contribution to form Dasan(茶山)'s I-xue in the later years.

고탁수 장기화 문제를 해결하기 위한 방법으로는 고탁수층을 선택취수하여 우선 배제함으로써 하류하천의 고탁수 발생일수를 최소화하는 방법이 있는데, 이와 같은 선택적 취수기법은 저수지 운영에 있어서 고탁수층을 우선 배제한 후 홍수기 이후에 저수지내로 유입되는 청수를 담수하여 호소 내 탁도 저감 효과를 얻을 수 있다. 본 연구에서는 선택취수 시 성층수괴의 동수역학적 변화를 분석하기 위하여 국내에서 처음으로 Two-tank 기법을 이용하여 성층구조를 구현해 내었는데, 소금물의 밀도변화를 이용하여 수심 1m의 성층수조를 만들었고, 밀도경사가 상이한 성층구조에서 취수조건을 변화시키면서 비교란 유속계인 PIV 시스템을 이용해 유속의 흐름을 Vector와 Contour로 분석하였다. 선택취수에 대한 흐름의 동수역학적 분석결과 취수유량보다는 밀도성층경사 변화에 더 민감한 반응을 보였다. 취수유량을 줄이거나 밀도성층경사를 급하게 했을 때에는 선택취수 영역(withdrawal zone)의 수직방향 폭은 줄어드는 반면, X축으로의 영향범위는 증가함을 나타냈다. 취수유량을 증가시키거나 성층밀도경사를 완만히 했을 땐 선택취수 영역(withdrawal zone)의 수직방향 폭은 증가하였고 X축으로의 영향범위는 축소됨을 나타내었다. 이 결과는 Richardson 수로도 판단되어지는데, Richardson 수가 증가하면 유속에 비해 상대적으로 밀도성층경사가 크다는 것인데 이럴 경우 선택취수 영역(withdrawal zone)의 수직방향 폭 최대가 되고 선택취수 영역(withdrawal zone)의 수직방향 폭은 최소가 된다. 선택취수 영역(withdrawal zone)의 수직방향 폭이 최소가 되면 취수구 직경 D의 1.8배의 값을 가지고 Richradson 수가 최소가 되더라도 취수구 직경 D의 3.3배를 벗어나지 않는다는 결과를 도출할 수 있었다.링 목적으로 사용될 수 있다. 본 연구에서 개발한 영상수위계는 한강홍수통제소 관할의 전류, 청담대교 등 4개소 낙동강 홍수통제소 2개소, 지자체 등에 적용되었으며, 적용 결과 비교적 안정적이면서 정확하게 수위를 측정하는 것으로 나타났다. 한편 기존 CCD 카메라 이외에 CCTV를 이용한 영상수위계를 개발하여 영상의 화질 개선뿐 아니라 하천화상 감시 기능을 강화하였다.소류의 섭취율은 높았다. 집단간의 상관도를 보면 교육별로 김치, 장아찌, 콩이 각각 p>0.5 수준에서 유의한 차가 없었고, 나머지는 유의한 차가 있었다. 연령별로는 멸치가 유의한 차가 없었고(p>0.5), 수입별로는 콩이 유의한 차가 없었다(p>0.5). 4. 영양지식(營養知識) 검토 가정생활(家庭生活)에 필요(必要)한 일반적(一般的)인 영양지식(營養知識)은 대체적으로 낮은 편이었다. 어린이 영양, 편식의 해로움, 비만증의 해로움, 임신부 그리고 수유부 영양에 대하여는 일반적으로 알고 있다고 하였으며, 그다음으로 이유기 영양, 어린이 발육에 필요한 식품, 식품과 영양소와의 관계, 우유의 성분, 노인영양에 대하여 잘 알고 있는 비율이 낮았으며, 인체의 영양소, 식단작성여부, 간식의 이론, 식품감별법에 대하여는 가장 낮은 비율을 나타냈다. 각 영양지식은 교육정도가 높을수록 영양지식이 높았고, 교육별 집단간의 유의한 차가 나타났다.

This essay seeks to answer the question of how best to understand Korean new religious movements (KNRMs). KNRMs have the characteristics of folk religion, ethno-religion, or popular religion. KNRMs are products of the national consciousness promoted by Korean society during the Late Joseon Dynasty at the turning point of modern Yi-Jing Studies. From the perspective of social evolutionary theory of developmental history, during that period, Joseon (Korea), like China, was faced with a double-edged sword consisting of the strength of tradition and the upheaval of modernity. If the strength of tradition depended on the Yi-Jing Studies to promote national enlightenment toward anti-imperialist aims, then it was equally the case that modernity depended on the sense of urgency to guide the people to secure livelihoods and edification regarding anti-feudalism. In this essay, the KNRMs that appeared during this transition period of Yi-Jing Studies will be a significant focus, and the worldview of Daesoon Thought will be the main focus. As one of the central topics, intensive discussion will be dedicated to the issue of the nature of pre-experientialism (先驗主義) which characterized the Great Opening (開闢). The principles of Daesoon Thought have a religious dimension of realistic awareness that guides the people's lives and edifies them. The process of the Great Opening aims to secure an ontological clock that tracks the Great Itineration of the world toward Daesoon Truth. This in turn as a process establishes the epistemological world of the Reordering Works of Heaven and Earth (天地公事) and reaches the axiological boundary of the future world. The links among the Three Realms is characterized by a pre-experientialist line that experiences the space-time nature of the universe as the Great Opening of the Later World (後天) within the framework of Heaven and Earth. Throughout this course, humans look to enjoy the infinite vitality of the universe from within their own finite vitality. Therefore, Daesoon Thought can overcome perceived reality through pre-experientialist channels such as the Great Opening of the Later World and aim for a state of self-awareness such as the Earthly Paradise. This is an attempt to participate and practice in the actual world rather than pursuing a world of transcendental ideas, and therefore, it tends to be proactive in the world rather than exhibit a passive tendency to be worldliness. In conclusion, the truth of Daesoon Thought, which is characterized by the Great Opening of the Later World, contains a future-oriented outlook that longs for a Nextopia full of hope and promise rather than idealistic fancy towards a Utopia or well-founded dread and disdain towards Dystopia.

Zhōuyì周易 is intended to explain the affairs of human beings by observing the images and works of all things in the universe, abstracting them into the $b{\bar{a}}gu{\grave{a}}$八卦, calculating the process and inducing the outcome by the method of stalk divination, in which this paper finds the origin of natural scientific thought of Zhōuyì. The way of Zhōuyì's thought on the natural science is distinguished from that of the Western's. In the West, people dismantled the objects into the parts until they reached the atom and analyzed them by the principle of causality to draw an axiomatic truth. In the meantime Zhōuyì observed and studied the dynamic functions and changes of all things for the convergence of the whole. While the way of Zhōuyì's thinking could have not contributed to the development of modern scientific development, that of the West overwhelmed Asian development passing through the period of enlightenment during 16-17 century. This paper tries to articulate the points where Zhōuyì can share its theory with the contemporary science by finding the traces of scientific thoughts in Zhōuyì. It encounters its ground from the methodology of natural science and scientific statements proposed by Zhōuyì. The essential concepts of Zhōuyì are induced from all things in nature. This can be considered as the idea of '法自然'(emulating the patterns and examples from nature). Also they observed the images and changes seen by the habits of animals, plants and human beings to sense and perceive their laws. These are regarded as the methodology of natural science in Zhōuyì. As a book of divination, the way of stalk divination is designed to calculate the future by using the system of 'numbers'. 'tàijí太極', ' yīnyáng陰陽', 'four symbols四象', '$b{\bar{a}}gu{\grave{a}}$八卦' and 'wǔxíng五行' are the essential concepts of Zhōuyì to represents the dynamic phenomena and changes of the natural order. Among them '$b{\bar{a}}gu{\grave{a}}$八卦' is a presentment to explain the structure of the world not by the individual analysis of things but by the unification of the whole through the contradictions and interchanges among them to reach the new orders. As of now, the studies of Zhōuyì in Korea have focused on the traditional perspectives, such as political and ethical philosophy. Some of recent studies, having interpreted Zhōuyì with scientific inclination have generated controversy 'Can Zhōuyì be a science?', for which scholars have hard time to reach the agreement. This paper tries to find the headwaters of the contemporary natural science by elaborating the methodology of natural science stated in Zhōuyì.
