The purpose of this study is to analyze the research published in Korea on the live atrium of Toegye Lee Hwang and present its applicability as a health dance program.To this end, Korean academic journals, the Korean Institute of Information Scientists and Engineers, and DBpia searched Korean journal publications with the keyword 'active visit', and 24 articles published from 1974 to December 2018 were classified into the Korean Research Foundation.According to the criteria, they were classified and analyzed into subclasses. As a result, first, the research trends of academic disciplines by year tended to increase the participation of various academic disciplines in the atrium.The interests of the live atrium differed in the order of physical education.Second, in terms of research subjects, more researches attempted to identify active atria as a research topic than research suggesting a plan.Third, the trends of the research topics were in order to study academic definition of live atrium, to find out the relationship between live atrium and other disciplines, to propose ways to use them, and to develop programs.Fourth, by applying the live atrium to a dance program, we found the potential as a dance program for health promotion.It is expected that these findings will not only provide the basic data for the possibility of a health dance program integrated with various fields, but also contribute to the search for the direction of health dance program research.

This paper illuminates the philosophical meaning of appropriateness(中節) in Yi Yik(李瀷) and Shin Hudam(愼後聃)'s theories of moral emotion. According to this paper, there was a difficult problem in Toegye Yi Hwang (退溪 李滉)'s philosophy. That is, How we could regulate the relation between Four Beginnings(四端) and appropriate Seven Feelings(七情). Yi Yik tried to solve this problem by elucidating philosophical significances of appropriate Seven Feelings as it were, one hand, he approved the morality of appropriate Seven Feelings, and on the other hand, differentiated appropriate Seven Feelings from Four Beginnings. Thereby He achieved to explain this problem. His solution was dependent on the concept of 'impartial sympathic spectator' that he suggested. It is valuable that Yi Yik reexamined the ethical meaning of appropriateness. His pupil Shin Hudam, however, criticised Yi Yik's opinion and identified Four Beginnings with appropriate Seven Feelings. Shin Hudam deconstructed the conceptual scheme of moral emotion suggested by Yi Yik and regarded appropriate Seven Feelings as Four Beginnings. According to Shin Hudam, the concept of appropriate Seven Feelings designed by Yi Yik was very ambiguous, actually there was no any dividing line between Four Beginnings and appropriate Seven Feelings. Both are equally moral principle manifestation(理發)and moral public(公). Now old concept category of moral emotion(Sadan and Chiljeong) was disappeared and new concept category of moral emotion was appeared, that is public and private.

Kim Ee-man was born and grew up in Jecheon (堤川). As a government officer and a Confucian scholar belonging to Namin School, Kim Ee-man was active in the early and middle of 18th century. Kim Ee-man composed good poems since he was a child. In addition to being a good poet, Kim Ee-man later became a model government officer, who had thorough awareness on serving citizens (爲民). When he was a governor in Yangsan (梁山) county, he built an embankment for farmers by out of his own salary. The academic world of Kim Ee-man faithfully succeeded the basis of Toegyehak (退溪學) and he took Sohak (小學) as important. The reason of Kim Ee-man having established a practical guideline in the form of inscription and proverbs was also directly related to the issue of moral practice. Kim Ee-man also received the influence of ancient classic study from his teacher Lee Seo-woo (李瑞雨) and took Yookgyeong (六經, Six Classics in China) important in practice. Kim Ee-man started the study on Joojahak (朱子學, the doctrines of Chu-tzu) in later years. He became more thorough in being a public figure while reinforcing effort on differentiating the principle of heaven (天理) and human desire (人欲).

This study aims to explore Yulgok Yi I(栗谷 李珥)'s political intention through his presenting Seonghakjibyo(The Essentials of the Studies of the Sages, 聖學輯要) to the King Seonjo(宣祖), paying attention to his political situation in early reign of the King. Until presenting the book to the King in December 1576(the 8th year of King Seonjo's reign), Yulgok had been neglected from the political development of the King. So his presenting Seonghakjibyo, which basically professed the perfection of the studies of the Sages(聖學), to the King included another aim to convert the King's negative view on him by synthesizing his political views and appealing to the King. Yulgok's political views are intensively summarized in the book's beginning "Jincha(進箚)" and the final chapter "Seonghyeondotong(聖賢道統)". Through "Jincha", he recalled the past of his political situation during early reign of the King and expressed his own will to participate in the government again by presenting this book that was the summary of his political views. Then through "Seonghyeondotong", he suggested his own specific political opinions to the King as the successor of Taotong(道統) in Chosun by expressing such an ethos that he succeeded directly to Chutzu(朱子). This study firstly tries to identify Toegye Yi Hwang(退溪 李滉)'s presenting Seonghaksibdo(The Ten Diagrams on Sage Learning, 聖學十圖) to the King and Yulgok's successive will on it. Then we will review the times till presenting Seonghakjibyo to the King, 8 years of early reign of King Seonjo when he had been neglected from the political development of the King. Finally we will specifically analyze how his political views are expressed in each beginning and final chapter of the book.

Yeoheon is a representative recluse and philosopher in the 17th Joseon dynasty. His contemporary intellectuals considered him as a sincere nobleman, Confucius in the Joseon, and moreover a saint, a cornerstone of culture, and a model for Confucianists. As a politician, he was regarded as practicing the stabilization of the people's livelihood and education, which are the key ideas of Confucian politics, when he serviced as a local governmental office twice. In addition, his ruler thought that he was right, wise, and modest, and therefore had the dignity of the old sage. His subordinates considered that he possessed the way of the old great ministers and the eye to see the current state of affairs. His theory of the Yijing is based on Cheng-Zhou learning, but developed their interpretation of the text. In addition, he discussed that Confucianism is a practical learning. His theory of the ritual was considered to follow Zhu Xi's works, but refer the old rituals and overcome the aspect of minor customs. His contemporary scholars thought that his theory of Neo-Confucianism revealed the essence of Li-Four and Qi-Seven theory regardless of scholarly parties, which were formed after Toegye and Yulgok. However, he proposed the Li-longitude and Qi-latitude theory in order to restore the real values, but it is similar to Yulgok's theory, which was criticized by the schools of Toegye and South Faction near Seoul. However, his theories revealed the fact that Joseon Confucianism cannot be simply differentiated as two major theories of "Centering on Li" and "Centering on Qi. In addition, his ideas of the universe and concern for the old showed that Joseon Confucianism is not just a theory, but is related to our lives and therefore practical in its nature.

Jeong Si-Han(丁時翰) completed "Siqibianzheng"("四七辨證") at the age of 72, and later had the argument over Runwuxingtongyilunzheng(人物性同異論爭) with his disciple, Lee Sik(李?). Jeong Si-Han(丁時翰) had the position of Runwuxingyilun(人物性異論) and Lee Sik(李?) Runwuxingtonglun(人物性同論). Yet, the argument over Runwuxingtongyilunzheng(人物性同異論爭) had been forgotten and "Siqibianzheng"("四七辨證") could be acknowledged because Toegye school(退溪學派) and Yulgok school(栗谷學派) were conflicting and criticizing each other's stance at that time. It seems like Lee Hyeon-Il(李玄逸)'s "Liqulishilunsiduanqiqingshubian"("栗谷李氏論四端七情書辨") had a great influence on the completion of "Siqibianzheng" ("四七辨證"). Lee Yi(李珥)'s thought of Siduan(四端) and Qiqing(七情) was 'the position of Hunlun(渾淪)' that 'Qiqing(七情) includes Siduan(四端)', and Lee Hwang(李滉) had the 'position of Fenkai(分開)' that Siduan(四端) and Qiqing(七情) should be interpreted differently. Jeong Si-Han(丁時翰) criticized the stance of Hunlun(渾淪) from the position of Fenkai(分開). What did Jeong Si-Han(丁時翰) try to pursue through "Siqibianzheng"("四七辨證")? This fact tends to make us forget the controversy over Runwuxingtongyilunzheng(人物性同異論爭) between Jeong Si-Han(丁時翰) and disciple Lee Sik(李?). Now we know the fact that Jeong Si-Han(丁時翰) criticized Lee Yi(李珥) in "Siqibianzheng"("四七辨證"), but don't care much about the fact that Jeong Si-Han(丁時翰) caused the controversy over Runwuxingtongyilun(人物性同異論). Why "Siqibianzheng"("四七辨證") has remained in our memory even though it was an important one? It might be because "Siqibianzheng"("四七辨證") had an impact on Lee Sik(李?), Shin Hu-Dam(愼後聃), and even Jeong Yak-Yong(丁若鏞) in the process of summarizing the arguments over Siduanqiqinglunzheng(四端七情論爭) since Jeong Si-Han(丁時翰) regardless of whether Jeong Si-Han(丁時翰) had hoped it or not.

본 논문은 도로투자 사업성분석시 사업주체의 현금흐름을 결정하는 항목들을 고정값(Deterministic Value)이 아닌 확률적으로 추정함으로써, 사업의 재무적 변동으로 인한 위험도를 민간사업자의 견지에서 사업성분석과정에 내재화하는 모형을 개발하는 것이다. 즉, 확률적 비용추정기법으로 국소적으로 활용되던 위험도분석을 재무모형에 내재화함으로써 사업의 재무적 변동을 보다 포괄적으로 분석할 수 있는 틀을 제공한다. 본 연구에서는 몬테카를로 시뮬레이션기법을 이용한 위험도분석(Risk Analysis)을 적용하여 사업성 평가지표와 비용의 확률밀도함수(Probability Density Function : PDF), 누적확률분포함수(Cumulative Distribution Function : CDF)를 산출하고, 그 결과로 해당 사업의 위험도를 고려하여 사업성을 평가한다. 이 모형은 사업의 모든 변동요인을 복합적으로 추정하여 사업기간 내 사업주체의 현금흐름을 분석할 수 있다. 따라서 사업주체는 효용에 따라 합리적인 위험도 관리 목표값(Target Value)을 선정하고, 사업의 위험도를 고려하여 건설비, 예비비를 결정할 수 있다. 본 연구에서 정립된 모형을 서울외곽순환고속도로(일산-퇴계원 구간)와 대전당진고속도로를 대상으로 사례분석을 수행하였다. 그 결과, 대전당진고속도로의 경우 사업성이 없으며, 서울외곽순환고속도로의 경우, 일부 위험도 발생변수를 합리적으로 관리한다면, 사업성이 충분한 것으로 분석되었다. 본 사례분석은 사업의 위험도를 반영한 사업성분석 방법으로 우리나라 민자유치대상고속도로의 사업성분석의 하나의 지침이 될 것이다.

기존에 개발된 수위-유량관계곡선을 이용하자면 때에 따라서는 이 곡선의 적용 범위를 벗어나는 저수위나 고수위의 수위-유량관계곡선이 필요하며, 따라서 기존의 수위-유량관계곡선을 외삽할 필요가 있다. 저수위에 대하여 외삽할 때에는 흐름이 0인 수위(GZF)를 안다면 이 수위와 유량측정자료의 최소치를 연결함으로써 오차를 최소화시킬 수 있지만, 보통 고수위의 범위에 유량측정자료가 있는 경우는 거의 없기 때문에 고수위에 대한 수위-유량관계곡선의 외삽은 거의 모든 경우에 필요하다. 또한 설계홍수를 추정하기 위한 자료, 즉 홍수수문곡선이나 연최대유량계열의 유량자료를 구성하기 위해서는 고수위에 대한 수위-유량관계곡선의 외삽이 반드시 필요하다. 기존에 고수위에 대한 외삽법은 수위-평균유속-통수단면적법, 횡단면 측량자료와 Manning 식을 이용한 방법 그리고 Stevens 방법이 있다. 하지만 각 방법들마다 많은 단점을 가지고 있어 적용에 있어서 세심한 주의가 필요하였다. 따라서, 본 연구에서는 기존 방법들을 응용한 고수위 외삽법을 제시 및 적용하였다. 실제 2007년 한강수계 유량측정 지점 중 총 6개 지점인 경안, 퇴계원, 성남, 중랑교, 시흥 그리고 신정 지점에 대하여 적용하였다.

현재 전국적으로 하천을 횡단하는 보에 어도시설이 되어 있는 곳은 4.6%에 불과하고, 기존에 설치된 어도의 경우에도 설계단계에서부터 회유성 어류의 통로로 부적합하거나, 시공 후 관리부실로 하상이 세굴되거나 퇴적되어 어도로서의 기능을 상실한 경우가 많은 실정이다. 또한 어도의 위치는 통수장애 및 퇴적을 고려하여 하천의 유심(流心)과 연결되는 위치에 설치해야 함에도 불구하고 엄밀한 수리계산 없이 어도의 설계가 이루어지는 경우가 많다. 따라서 본 연구에서는 1차원 및 2차원 흐름해석을 통해 어도 효율을 높일 수 있는 방안을 강구하였다. 흐름해석 대상구간은 왕숙천의 퇴계원 수위표 지점부터 상류 약 4km 구간이며, 이 구간에 3개의 보가 존재한다. 상하류 연속성 확보를 위해 어도 설치시 고려 대상 종으로 왕숙천 중류에만 출현하는 긴몰개를 삼았다. 보에 어도가 없는 상태에서 흐름 및 하상변동 해석을 수행하여 이를 바탕으로 어도를 설치하기에 적정한 위치를 도출하였다. 2차원 흐름모형의 하나인 RMA-2를 사용하여 유심선을 파악하였으며, 하상변동 해석 모형인 SED-2D를 이용하여 홍수시 어도 입,출구에 예상되는 세굴 및 퇴적양상을 확인하였다. 갈수시 설치된 어도에 충분한 유량이 확보되는가를 확인하기 위해 HEC-RAS를 이용하여 1차원 흐름해석도 병행하였다. 2차원 흐름해석 결과 대상구간의 좌안쪽으로 유심선이 발생하므로 어도는 이를 따라 보체의 좌안쪽에 설치함이 타당하다. 그러나 홍수시 하상변동해석 결과, 좌안쪽에 상당량의 퇴적이 발생하는 경우에는 퇴적이 진행되지 않는 보의 중앙부에 어도를 설치함이 타당하다고 사료된다.

In most PFI(Private Finance Initiative) projects in Korea, the project management are in charge of the Special Purpose Company(SPC) established for carrying out the project. This paper is a case study about an owner CM executed by the organizations and staffs of SPC itself. : Seoulbeltway (Ilsan $\~$ Toegaewon) Private Investment Project. In time management area, the SfC was the leader of project management throughout the life circle - plan, design, permit, construction, operation and maintenance - beyond the schedule manager's role. In cost management area, the methods of reducing the total costs by VE, new technologies, etc. has been needed assuming the construction risks were subject to SPC.
