The purpose of this study is to analyze the identity and relationship of library and information science by exploring theoretical aspects of LIS research, including theory building and theory use. The sample of this study consists of 1,661 research articles published from 1984 to 2003 in two Korean and two American core LIS journals. Theory articles are analyzed with two scales, such as '4-degree of theory efficiency' and '5-degree of theory use' Each article is coded in terms of journal, country, publication year, subfield, and methodology of the article. and affiliation, department, and research experience of the first author. The theories used therein are coded according to their origin and age. Also, an author co-citation technique is applied to represent intellectual structure on a two-dimensional map, which has been constructed by theory use of LIS authors fur 20 years.

This study investigated Hua Tuo's Shang-han theory, which precedes the period of Zhang Zhong Jing's Shang-han theory, and considers the relationship between the two approaches. Researchers compared terminology and language of Hua Tuo's Shang-han theory as published in Theory in Qian Jin Yao Fang and Wai Tai Mi Yao, with Zhang Zhong Jing's Shang-han theory. In Hua Tuo's theory, Shang-han involves pathogenic invasion of the body surface, where the pathogen transforms to 6 different stages, Pi (皮), Fu (膚), Ji (肌), Xiong (胸), Fu (腹), Wei (胃). Among these, the stage sof Pi (皮), Fu (膚), Ji (肌) can be considered as exterior syndrome (表證). Those that invade the lower chest can be considered as lower chest disease, and those that violate the abdomen or stomach can be considered as Interior heat excess syndrome (裏熱實證). Stomach heat excess syndrome (胃中實熱證) is the most severe and is similar to septicaemia or bubonic plague. Hua Tuo's treatment used three methods which are 汗 (perspiration), 吐 (emesis), 下 (purgation). In the case of Phlegm syndrome (痰?證), HuoTuo's theory was similar to Zhang Zhong Jing's Shang-han exterior syndrome (傷寒表證) and therefore used Zhuling-powder (猪?散). In the case of deficiency hot flush Syndrome (虛煩證) in Shang-han disease, HuoTuo uses ZhuYe-decoction (竹葉湯), of which the drug contents is the same as Zhang Zhong Jing's ZhuYeShiGao-decoction (竹葉石膏湯), which was used for the same condition.

Enhanced lower order shear deformation theory is developed in this study. Generally, lower order theories are not adequate to predict accurate deformation and stress distribution through the thickness of laminated plate. For the accurate prediction of detailed stress and deformation distributions through the thickness, higher order zigzag theories have been proposed. However, in most cases, simplified zigzag higher order theory requires $C_1$, shape functions in finite element implementation. In commercial FE softwares, $C_1$, shape functions are not so common in plate and shell analysis. Thus zigzag theories are useful for the highly accurate prediction of thick composite behaviors but they are not practical in the sense that they cannot be used conveniently in the commercial package. In practice, iso-parametric $C_0$ plate model is the standard model for the analysis and design of composite laminated plates and shells. Thus in the present study, an enhanced lower order shear deformation theory is developed. The proposed theory requires only $C_0$ shape function in FE implementation. The least-squared energy error between the lower order theory and higher order theory is minimized. An enhanced lower order shear deformation theory(ELSDT) in this paper is proposed for smart structure under complex loadings. The ELSDT is constructed by the strain energy transformation and fully coupled mechanical, electric loading cases are studied. In order to obtain accurate prediction, zigzag in-plane displacement and transverse normal deformation are considered in the deformation Held. In the electric behavior, open-circuit condition as well as closed-circuit condition is considered. Through the numerous examples, the accuracy and robustness of present theory are demonstrated.

Huang di's Four Classics introduces the first full-scale Yin-Yang theory. The ancient idea of Yin-Yang could be classified systematically throughout Huang di's Four Classics and make itself the cause of creation, movement, and variation. The Tao of essence and Reason-Law(理法) is a single 'One'(一) and completes the reality of Tao adopting Yin-Yang as an elementary. The elementary of Yin-Yang has rules and laws and then the Tao manifest itself through Yin-Yang. The features of Yin-Yang theory in Huang di's Four Classics are placed on the explanation of the structure of the universe embodied as class and system. The class and system are the structured worlds in the space based on the upper and lower sides Yin-Yang idea(上下陰陽觀). It means the system by Yin-Yang theory, corresponding to the flat structure of the Sky and the Earth mentioned in Gaitian theory, one of the ancient theory of the universe structure. By adopting Huang di's Four Classics' Tian-zhi Yin-Yang theory(天地陰陽論) and developing the class system in human bodies, The Hwangjenegyeng appreciates human bodies as a whole. In addition, by applying Four seasons Yin-Yang theory not only to human bodies but also to the space of Liu-he(六合) and the time of Four Seasons(四時), it developed Yin-Yang theory of Huang di's Four Classics more abundantly and embodied Yin-Yang theory in many fields including physiology, pathology, diagnostics, and prescriptions.

A time-dependent large deformation fracture theory is developed for application to soft biological tissues. The theory uses the quasilinear viscoelastic theory of Fung, and particularizes it to constitutive assumptions on polyvinyl-chloride (PVC) (Part I) and cartilage (Part II). This constitutive theory is used in a general viscoelastic theory by Christensen and Naghdi and an energy balance to develop an expression for the fracture toughness of the materials. Experimental methods are developed for measuring the required constitutive parameters and fracture data for the materials. Elastic stress and reduced relaxation functions were determined using tensile and shear tests at high loading rates with rise times of 25-30 msec, and test times of 150 sec. The developed method was validated, using an engineering material, PVC to separate the error in the testing method from the inherent variation of the biological tissues. It was found that the the proposed constitutive modeling can predict the nonlinear stress-strain and the time-dependent behavior of the material. As an approximation method, a pseudo-elastic theory using the J-integral concept, assuming that the material is a time-independent large deformation elastic material, was also developed and compared with the time-dependent fracture theory. For PVC. the predicted fracture toughness is $1.2{\pm}0.41$ and $1.5{\pm}0.23\;kN/m$ for the time-dependent theory and the pseudo-elastic theory, respectively. The methods should be of value in quantifying fracture properties of soft biological tissues. In Part II, an application of the developed method to a biological soft tissue was made by using bovine humeral articular cartilage.

Philosophers Of aeBthetics have tended to limit their Suhject to include only objects Of art. In contrast to art objects, landscapes include elements of both art and nature, and the aesthetic experiences of landscape are ordinarty ones. Thus, the theoretical alternatives, that cannot be like the traditional aesthetic dogma of art, must be explored. Jay Appleton's theory is the firsts attempt to develop a comprehensive theory of landscape aesthetics. He concentrates on the question 'what do we like about landscape and why do we like it ' He takes the assumption that the aesthetic experience of landscape is pleasurable or satisfying, and suggests the biologically oriented theory, called 'prospect-refuge theory.'Although his theory is stimulating and highly speculative, it depends on the 'aesthetic attitude' theory of Kantian thought. His theory can be criticized for its biologically deterministic nature and its reductionism To respond to Appleton's shortcomings, that is, to resolve the conflict between biological and cultural explanations of aesthetic experience of landscape, Steven Bourassa tries to combine biological, cultural, and personal modes in a comprehensive paradigm for research in landscape aesthetics. This tripartite paradigm seems to promise to be meaningful if helping to pose important questions as well as in. avoiding conceptual errors about aesthetic domain of landscape. However, Bourassa's theory fails to integrate such three separate kinds of moder In the final analysis both Appleton and Bourassa present same succeases in expanding the scope of aesthetics to embrace landscape. Most important for a theory in landscape aesthetics must be its ability to enlarge our awareness of the aesthetic domain and its sound logic and evidence to criticize our problematic beliefs about he aesthetic idea of landscape.

Wittgenstein presents so-called picture theory in the Tractatus Logico-Philosophicus. What is, then, the point of the picture theory? What are the philosophical problems which the picture theory tries to solve? In this paper, I will endeavor to show that the object of a picture is different from the sense of a picture, that the representing relation is different from the projective relation, that picture theory is applied to composite propositions as well as elementary propositions and that on the one hand the basic problems that picture theory tries to solve are problem of theory of meaning and that of theory of truth, but on the other hand the more important problem is what Wittgenstein calls "the mystery of negation." From these discussions, we can see that it is not correct at all to interpret that the picture theory in the Tractatus Logico-Philosophicus is nothing but an analogy which does not have a significant content.

This paper examines whether the conceptual metaphor theory, which has been recently treated as important research topic in the field of cognitive linguistics, can be a new method that can promote the modernization of basic Korean medicine (KM) theory. In addition, the significance and potential of this study are reviewed by looking at Chinese research cases that applied this theory to Traditional Chinese Medicine theories and terminologies. The results are summarized as follows. From the viewpoint of metaphoric cognition, KM is a medicine that attempts to understand the human body (microcosm) through nature (great universe) by metaphorically projecting human experiences of nature on the human body based on the thought of correspondence between nature and human (天人相應). The language system of KM is based on a metaphor that extends our experience of nature to the human body, and an abundance of metaphors can be seen throughout the language of KM. Understanding and interpreting KM theories and terminologies from a metaphorical point of view allow us to understand the nature of KM theoretical key terms more deeply than now. And this understanding can help define and describe KM theoretical key terms and promote the modernization of KM theory research. In addition, various image schema that plays an important role in the metaphorical expansion of physical experience can be used for modeling KM theory. Research of KM theories and terminologies from a metaphorical point of view can serve as a bridge between traditional KM theory and modernization research, opening a new path to the modernization of basic KM theory in difficult situations.

Sense-Making Theory gives persuasive power to information seeking behavior while acknowledging the diversity of subjects. It is being used as a theory and methodology to explain the phenomenon of information seeking in various temporal and spatial contexts related to the communication of individuals' inner realms, face-to-face, organization, and mass communication. However, it is not to be a theory to explain the information seeking behavior of a group in that it explains the individual epistemological interpretation of the subjects. Also, the purpose of the theory was to establish a receiver-centered communication theory that constructs sense-making by itself, away from the receiver who unilaterally accepts the sender's information from the perspective of communication theory. However, Dervin accepted the existence of object information without explaining the relationship between the recipient's external information and the receiver. Owing to the establishing his concept of information following the Popper(1972)'s world concept, its object of observation is not World III(objective content of thought), but the process of sense making in which World II(psychological world) receives information generated in World III. In this context, Dervin's theory is not to explain the communication behavior at a group level.

Purpose: This study examined the trends in domestic research that applied theory to diabetes patients to suggest future directions of nursing practice and research for diabetes patients. Methods: This scoping review followed the Joanna Briggs Institute guidance. The population was diabetes patients; the concept was a research that applied theory and had no limitations in context. Eligible studies were retrieved from electronic databases of RISS, KMbase, KoreaMed, NDSL, NAL, and nine major domestic nursing journals. Of the 509 retrieved articles, 20 studies met the inclusion criteria. Results: The study included the community (57.1%), and the subjects were mainly type 2 diabetes patients (42.9%). The Information-Motivation-Behavior skills (IMB) model was the most applied theory (36.4%). The theories were primarily from psychology disciplines (72.7%) and predominantly applied as a conceptual framework of the study (55%). Conclusion: The studies that applied theory were conducted mainly in the community. The IMB model was the most applied theory, and the theory was most applied as the conceptual framework. Efforts to close the theory-practice gap and further studies on developing nursing interventions based on theory and verifying their effectiveness are needed to improve nursing practice and study for diabetic patients.
