1. Purpose Lee Je-Ma had continued to revise "Donguisusebowon" by adding the contents of the Symptomatic-pharmacology(病證藥理論) on Soeumin, Soyangin and Taeeumin to it from the first establishment of the old version in 1894 to 1900.(new version). This paper tries to find out the contents and meaning of the Discourse on the Constitutional Symptoms and Diseases(病證論) between the old version and new version and what the Discourse on the Constitutional Symptoms and Diseases affected the Theory of Eight Constitution created in subsequent years. 2. Methods I classified the Discourse on the Constitutional Symptoms and Diseases in "DongYiSuseBowon" into old version and new version and tried to find out the Theory of Eight morbidities(8病證論) which is the predecessor of the Theory of Eight Constitution, before reviewing their relation. 3. Conclusions 1) The Discourse on the Constitutional Symptoms and Diseases in the old version specify that the externally sensed diseases are caused by the deep sediment of nature(性) and that the internally touched diseases are caused by the violent activities of emotion(情). In addition, it said that all diseases are caused by the specific characteristics of patient's smaller internal organs(偏小之臟). But in new version, the diseases were understood through the concept Exterior, Interior, Heat and cold(表裏寒熱). The new version said that the diseases may be caused not only the specific characteristics of patient's smaller organs but also by bigger organs(偏大之臟). 2) The Theory of Eight Constitution was derived from the Theory of Eight morbidities, in which all kinds of human diseases are caused by 8 disease-orgin organ and that the diseases therefore can be classified into 8 morbidities. The Theory of Eight morbidities reorganized the Discourse on the Constitutional Symptoms and Diseases in "DongYiSuseBowon" by classifying them into first morbidity and second morbidity. 3) The Discourse on the Constitutional Symptoms and Diseases in "DongYiSuseBowon" has decisively affected the creation of the Theory of Eight morbidities which is the predecessor of the Theory of Eight Constitution. The Theory of Eight morbidities may be deemed another interpretation of the Discourse on the Constitutional Symptoms and Diseases in "DongYiSuseBowon". As the Theory of Eight morbidities put emphasis on the genetic characteristics, the Theory of Eight Constitution stating that Eight morbidities are caused by different specific constitution was derived.

본고는 상수역학(象數易學)과 수학(數學)의 관계에 관한 논문이다. 역학(易學)은 "주역"의 팔괘(八卦)의 상, 음양오행설(陰陽五行說), 자연과학적 지식을 바탕으로 형성된 경학(經學)의 한 학과이다. 한초(漢初)에서 청말(淸末)까지 역학의 발전과 전개에서 상수는 주요한 개념이자 이론으로 자리해왔다. 그리고 이러한 상수역학의 전개에는 수학적 표현체계가 잠재해 있었다. 본고는 진법(進法)과 잉여수(剩餘數), 배수(倍數)와 수열(數列), 구궁도(九宮圖)와 원주솔(圓周率), 비례식(比例式)의 수학적 지식이 상수역학 속에서 어떻게 표현되었는지를 고찰한다. 이들은 역대 역학가들이 "주역"의 연원문제, 괘 효사 해석문제, 우주론의 문제를 논하면서 이용했던 수학적 표현체계들이다. 상수역학은 수학뿐만 아니라 기타 자연과학 즉 천문학, 의학 등과 조응하면서 그 내용을 풍부히 했고, 그 사상을 다양화했다. 상수역학은 이렇게 자연과학의 발전궤적과 함께 자신의 사상과 표현체계를 달리해왔다. 본고는 상수역학이 자연과학과의 조응 속에서 전개 발전 되었다는 전제 속에서 역학의 수학적 표현체계를 개괄한다. 그리고 개괄한 사실들로부터 상수역학이 자연과학과의 조응 속에서 전개 발전한다는 전제를 논증한다.

Niklas Luhmann은 사회학 이론가들 중 가장 논쟁적이고 난해한 학자이면서 동시에 근 10년간 후속연구가 증가하고 있는 학자이다. 이 연구의 목적은 Luhmann의 후속연구들이 Luhmann의 난해한 개념을 어떻게 사용하고 있는지를 관찰하는 것이다. 이 연구는 선행연구와 달리 분석의 단위를 논문이 아니라 키워드로 채택하였다. 키워드는 개념을 관찰 가능하게 만드는 언어적 구성물이기 때문이다. Web of Science의 검색결과 나온 139편의 사회과학 분야 논문의 키워드를 동시출현빈도 분석하였다. 연구 결과는 다음과 같다. 첫째, 가장 중요한 키워드가 Luhmann의 이름과 이론의 이름이었다. 둘째, 클러스터링은 사회적 체계 이론, 일반체계이론, 법 체계와 정치체계, Luhmann 이론의 사회이론적 의의 등 4가지로 묶였다. 셋째, 핵심어가 'systems theory(일반체계이론)', 'communication(소통)', 'Autopoiesis(자기생산)', 'risk(위험)', 'legal system(법 체계)', 'functional differentiation(기능적 분화)', 'environment(환경)', 'social theory(사회적 이론)', 'sociological theory(사회학적 이론)', 'structural coupling(구조적 연결)', 'systems(체계들)', 'evolution(진화)'로 도출되었다. 이 연구의 의의는 다음과 같다. 첫째, 핵심어를 도출해내 Luhmann의 이론을 처음 접근하는 사람들에게 유용한 접근점을 제공하였다. 둘째, 난해한 이론적 연구의 동향 분석에도 키워드 네트워크를 통한 내용분석이 가능함을 증명하였다.

In the present work, a simple first-order shear deformation theory is developed and validated for a variety of numerical examples of the thermal buckling response of functionally graded sandwich plates with various boundary conditions. Contrary to the conventional first-order shear deformation theory, the present first-order shear deformation theory involves only four unknowns and has strong similarities with the classical plate theory in many aspects such as governing equations of motion, and stress resultant expressions. Material properties and thermal expansion coefficient of the sandwich plate faces are assumed to be graded in the thickness direction according to a simple power-law distribution in terms of the volume fractions of the constituents. The core layer is still homogeneous and made of an isotropic material. The thermal loads are considered as uniform, linear and non-linear temperature rises within the thickness direction. The results reveal that the volume fraction index, loading type and functionally graded layers thickness have significant influence on the thermal buckling of functionally graded sandwich plates. Moreover, numerical results prove that the present simple first-order shear deformation theory can achieve the same accuracy of the existing conventional first-order shear deformation theory which has more number of unknowns.

Massive Open Online Course (MOOC) is online education that anyone can register for free and has internet access. MOOC is also called Education Revolution and is spreading rapidly all over the world. Although recent MOOC high-quality classes may enhance the value of MOOC, MOOC learning still needs much research. Since MOOC has low learning completion rate and continuous use rate, various studies on the reasons that learners give up at the beginning of learning have not been tried yet This research is studied for the continuous intention of use of MOOC applying self-determination theory and learning flow theory based on technology acceptance model. In particular, the research are conducted for cultural difference in continuous usage of MOOC between Korean and Chinese. The research results show that self-determination theory applying perceived autonomy, perceived competence, and perceived relatedness and learning flow is useful to explain continuous use of MOOC. The research also shows that Hofstede theory works well in explaining the cultural difference between Korea and China in continuous usage of MOOC. The result shows that korean is more influenced by perceived external motivation like perceived usefulness and chinese is more influenced by internal motivation like learning flow in continuous use of MOOC.

This thesis is to discuss and prove the identity of the acts of the library and the character of the library which regards these as its objects. And this study is analyzed in view of per ceptual problems and scientific problems and scientific problems, in order to make clear the character of the acts of the library. In these processes, some basic propositions are extracted. First, culture can be found in arranged order. Second, human being can create culture by the acquisition of accmulated culture. Third, an individual is purposely related with culture. Fourth, culture is antonomous to mankind. And in this thesis, library science is defined as the systematic formation of mankind's pursuing acts, and to identify this definition, some theoretical models of library science have been offered as follows : Model I 1. Theory of making culture assets informative. 2. Theory of making culture assets empirical; that of imformation treatment. 3. Theory of medial acts of librarians. Model II 4. Theory of organic systems of libraries. Model III 5. Theory of guiding school activities. 6. Theory of extending the inhabitants' interests of communities. 7. Theory of a kind of resources in social improvement. Model IV 8. Theory of a means of principal approach to the succession of culture. In conclusion, this study is to prove that acts of libraries are the universal ones of those human being that are gualified to be the unique means to the creation of culture and, library science is a science that shapes concepts and rules to describe, to make explanation and to foretell these acts.

Objective : Zhang, Zhongjing(張仲景)'s Sanghanlun(傷寒論) is based on Six-channels system(六經) to classified a disease. But the notion of Six-channels system seems to be a very various angles. For example, Meridian and collateral theory(經絡說), Viscera and Bowels theory(臟腑說), Grade theory(段階說), Surface theory(地面說), Symptoms theory(症候群說), Six-disease theory(六病說), Eight principle pattern theory(八綱說) and all the rest of it. Above all things Meridian and collateral theory was very frequently quoted to explain the Six-channels system(六經). But it's true notion is not restrict to a meridian vessel(經脈). Method : I will try to describe the Sanghanlun's Greater yang disease(太陽病) through the Ke-qin(柯琴)'s Taiyangbingjie(太陽病解), and I would like to point out that the existing perception that Greater yang(太陽) is connected with Bladder meridian(足太陽膀胱經) is wrong. Result : Ke-qin's Taiyangbingjie explained the greater yang disease was connected with Heart(yang within yang), which was located in the top half and the outer layer of the body. In addition to the presence of the diaphragm or lungs are involved with. Conclusion : Practical meaning of greater yang disease is not connect with Bladder meridian, but it is related to the Heart and Lung for maintain the Nutrient and defense circulation (營衛循環).
