  • Despite the number of developed theories, it still remains a difficult task for some established and emerging scholars in various academic fields to clearly articulate new theories from research studies. This paper reviews and collates the views of scholars on what a theory is and how a good theory can be developed. It explains the concept of a theory, and the different components that make up a theory. The paper discusses the different processes of theory development by emphasizing what theory is and what theory is not. This review found that scholars differ in their definition of a theory, which leads to using terms such as model, paradigm, framework, and theory interchangeably. It found the lack of theoretical constructs in a study to be one of the factors which explains why articles are rejected for publication. This paper may be of benefit to established researchers who may be struggling with theory development, and especially younger academics who are the future of scholarship in various academic fields, particularly in information science.

  • The meteorological elements were measured to investigate cause of summertime ice formation at Unchiri, Gangwon Province. The cause of freezing at valley was conformed as adiabatic expansion theory, latent heat of evaporation, natural convective theory, cold air remain theory, and convective freezing theory according to former study. However nither theory produced a satisfactory explanation. This studying area is not valley but ridge, and underground water surface exists at below than freezing height. wintertime temperature drop and summertime cold air spouting were explain as natural convective theory, generation of water drop on the rock was explained as cooling theory by air expansion, and ice formation on the rock was explained as adiabatic expansion theory. In conclusion, formation of ice valley at Unchiri was formed by natural convective theory, adiabatic expansion theory, and latent heat of evaporation successively.

  • This paper deals with the current phonological theory named the elementary theory Before manipulating this theory with highest depth, we need to discuss the distinctive feature theory which can be estimated as playing a central role in the standard generative trends. En the element-based phonological theory, the followings might act as tile main traits in differentiating it from other theories: the notion of phonological opposition is regarded as privative one, treating the univalent element as an analysing unit in a phonological process instead of distinctive features, and the nile convention in standard theory is replaced by the element. In chapter 2, a brief history of generative theory is to be described with respect to the merits and demerits of the distinctive feature theory. In chapter 3, After dealing with the current tendency and some prominent aspects of each element theory, a couple of problems thought to be confronted by the distinctive feature theory And the analysing method taken from the element-based theory which may be regarded currently as the alternative to the problems mentioned above will be discussed mainly, The government-based theory introduced by KLV(1985, 1988) may be the main target in discussing the current topic.

  • Previous studies have found that the use or development of theory in library and information science (LIS) research is comparatively low and may be trending downward. LIS has also been criticized for relying on theories imported from other disciplines rather than applying or developing theories from within. The theory of information worlds, a social information behavior theory originally introduced in 2008, represents a newer LIS theory whose level of adoption is understudied. This study features a systematic literature review of peer-reviewed research articles which cited or used the theory of information worlds from 2008 to early 2022 to identify trends related to levels of theory use, publication venues, author affiliations, countries, and collaborations, as well as research methods, topics, and populations. Findings suggest that both awareness and use of the theory of information worlds are positively trending, though at slower rates for higher levels of theory use, such as full applications of the theory to guide the collection and analysis of empirical data. The theory has also been used by researchers from around the world and across disciplines, most often with mixed and qualitative methods. While the growth of a new LIS theory is promising, the authors echo calls for increased use and development of the theory of information worlds, and other LIS theories more broadly, and as more interdisciplinary collaboration.

  • International trade theory is largely divided into the pure theory of international trade and the theory of trade policy. The pure theory of international trade is an academic field that conducts research related to the trade flow of goods and services between countries and the movement of production factors across borders. Meanwhile, the theory of trade policy studies the positive and normative aspects of trade policy which a government adopts to achieve its policy goals. In this study, about 230 papers in the field of international trade theory published in the Korea Trade Review over the past 45 years (1975~2019) are examined in meta analysis by period and subject. First, this study provides the main research subjects of international trade theory, and historically reviews the overall development of trade theory by paying attention to the core and pioneering papers, domestic and foreign. Second, the publications in the field of trade theory are classified by subject, and the domestic and foreign research trends are also examined for each subject with the analysis of major publication of this Journal.

  • Objective The purpose of this study was to show that the characteristics of the Sasang Constitutional Medical theory(SCM) are different from the traditional medical theory by comparing their theories of humans and pathophysiology. Methods The establishments and developments of the traditional medical theory were reviewed. Then the hypothesis that the theoretical foundation of SCM is different from that of the traditional medical theory was tested by comparing the traditional medical theory and SCM with respect to the theories of humans and the reconstructed theory of pathophysiology. Results The main findings of this study can be summarized as follows. 1. The theory of SCM reconstructed the traditional medical theory by shifting the paradigm concerning the structure of human existence. 2. The theory for SCM reconstructed the theory of pathophysiology by expanding Confucian moral theory from an experiential perspective. 3. The theory of SCM categorizes humans into four constitution groups according to congenital individuality in emotional expressions and pathophysiological functions. The categorization is based on medical treatment through which it was found that there are congenital individuality in the expression of his moral feelings. 4. The reconstructed pathophysiological theory of the SCM provides the foundation for establishing a verifiable medical theory. Discussion and conclusion The Sasang Constitutional Medical Theory is based on the idea that humans do not follow the changes of Nature but pursue morality and wealth in the Sasang system of the Heavenly qi and human affairs. Therefore, the theory is founded on Confucian moral theory but develops its own view of the theory of pathophysiology by way of experiential interpretation.

  • Purpose: This study was to understand to the nursing theory frame contained in the traditional philosophy and western nursing theory for the theory development fit for Korean people and to identified the strategy for nursing theory development. Method: To perform this study various relevant texts-western, eastern, classical and contemporary were reviewed. Result: The metaparadigm of the nursing in western considers four major factors-Human being, Environment, Health and Nursing. In Korea, the metaparadigm of nursing considers three major factors-Universe, Human being (body, life, health, disease) and Nursing. The key strategy for establishing comprehensive nursing theory which combines both western and eastern is to study the nursing literature based on eastern and western philosophy. Theorists should study the life and culture of the specific nation in order to understand the essence of the thoughts and psychology of the patients and to investigate the phenomena, which will be the foundation of theory development. Conclusion: Western nursing theory must be utilized to provide practical framework for the development of nursing theory, and practical approach is necessary for combining western and eastern theory.

  • Clausewitz’s theory of war can be divided between the theory of conduct of war and the theory of preparations for war, and the theory of war that Clausewitz means, is the theory of conduct of war. But before Clausewitz, men regarded a theory of preparations for war as the theory of war. The theory of preparations for war concerns generally about the material side of war, but not its spiritual aspect. The activity of war is basically a human spiritual and psychological action. And because the war is dangerous, the anxiety occurs and diverse human feelings, for example courage, have been required. Also the informations in war is normally very uncertain, so an insight of the commander is in war very needed. The Theory of war has to consider this spiritual aspect. To end the war and to acquire the peace, an excellent talent of commander is necessary. And it is a genius. Men who are difficult to move but have strong feelings, these are the men who are best able to be a genius.

  • Aging is a senescence and defined as a normal physiologic and structural alterations in almost all organ systems with age. As Leonard Hayflick, one of the first gerontologists to propose a theory of biologic aging, indicated that a theory of aging or longevity satisfies the changes of above conditions to be universal, progressive, intrinsic and deleterious. Although a number of theories have been proposed, it is now clear that cell aging (cell senescence) is multifactorial. No single mechanism can account for the many varied manifestations of biological aging. Many theories have been proposed in attempt to understand and explain the process of aging. Aging is effected in individual by genetic factors, diet, social conditions, and the occurrence of age-related diseases as diabetes, hypertension, and arthritis. It involves an endogenous molecular program of cellular senescence as well as continuous exposure throughout life to adverse exogenous influences, leading to progressive infringement on the cell's survivability so called wear and tear. So we could say the basic mechanism of aging depends on the irreversible and universal processes at cellular and molecular level. The immediate cause of these changes is probably an interference in the function of cell's macromolecules-DNA, RNA, and cell proteins-and in the flow of information between these macromolecules. The crucial questions, unanswered at present, concerns what causes these changes in truth. Common theories of aging are able to classify as followings for the easy comprehension. 1. Biological, 1) molecular theories - a. error theory, b. programmed aging theory, c. somatic mutation theory, d. transcription theory, e. run-out-of program theory, 2) cellular theories - a. wear and tear theory, b. cross-link theory, c. clinker theory, d. free radical theory, e. waste product theory, 3) system level theory-a. immunologic/autoimmune theory, 4) others - a. telomere theory, b. rate of living theory, c. stress theory, etc. Prevention of aging is theoretically depending on the cause or theory of aging. However no single theory is available and no definite method of delaying the aging process is possible by this moment. The most popular action is anti-oxidant therapy using vitamin E and C, melatonin and DHEA, etc. Another proposal for the reverse of life-span is TCP-17 and IL-16 administration from the mouse bone marrow B cell line study for the immunoglobulin VDJ rearrangement with RAG-1 and RAG-2. Recently conclusional suggestion for the extending of maximum life-span thought to be the calory restriction.
