Gi(氣) transformation theory is the foundation of Traditional Chinese Medicine[TCM]. This theory matured during the period of "Hwangjenaegyeong(黃帝內經)", and later in the history of TCM was a source of significant impact on the development process and direction of general medical theory. The concept of "gi transformation[氣化]" mainly originates from the definition of the three levels which are nature, the relationship between nature and human, and the body's own metabolism, and is used to describe the usage and the resulting changes of 'gi(氣)'. Gi transformation possesses six characteristics which are permanence, universality, representationalism, directional, variability, and orderliness. The research of the concept and characteristics of gi transformation[氣化] in "Hwangjenaegyeong" will help identify the important academic value and practical significance of the formation of the basic theory of TCM as the result of the gi transformation theory, and highlight the unique characteristics of TCM.

이 논문은 국내 해양영토 정책을 분석한 것이다. 해양영토는 본래 국가영역(territory)에서 영해 하층토(subsoil)의 해저지형을 말한다. 정책적으로 해양영토는 영해와 배타적경제수역(EEZ), 대륙붕 등 우리나라 주권(sovereignty)이나 주권적 권리(sovereign rights)가 미치는 관할 해역을 넘어서 도서(島嶼)와 극지를 포함하는 광의적인 개념으로 해석된다. 또한, 국내 연구자 사이에서 해양영토는 독도 등의 도서 영토에서부터 이어도 등의 EEZ와 같은 해역(maritime zone)을 광범위하게 지칭하는 데 쓰이기도 한다. 이 연구의 목적은 이처럼 다양한 국내 해양영토의 개념을 검토하고, 정책의 형성과 변천을 살피는 것이다. 이러한 연구목적에 따라 이 연구의 구성은 다음과 같다. 2장에서는 해양영토 관련 기존의 논의를 검토하고, 이를 바탕으로 해양영토의 개념을 분석한다. 기존 학계에선 해양영토 개념에 관한 충분한 논의가 부족했고, 그 결과 해양영토라는 용어가 섬과 무분별하게 사용됐다. 이 장은 그러한 해양영토 개념을 심층 분석했다. 3장은 해양영토 정책의 형성 과정과 그 변천을 추적한다. 오늘날 국내 해양영토 개념은 공공영역에서 비로소 완성됐다고 볼 수 있다. 이를 설명하기 위해 국내 해양영토 정책의 사령탑인 해양수산부의 활동을 정리한다. 4장에선 해양영토 개념과 유사성을 보이는 중국의 남색 국토(藍色國土)와의 비교를 통해 그 개념을 분석한다. 중국의 남색국토 개념은 오늘날 중국의 해양활동을 위한 정책적 토대로서 해양영토와 여러 유사점이 있으므로, 이 두 가지를 비교하는 것이 유의미하다고 판단했다. 이를 통해 마지막 5장에서 해양영토 정책추진을 위한 제언을 도출한다.

A new concept of reduced quasi-dimensional combustion model for a direct injection diesel engine is developed based on the previously developed quasi-dimensional multi-zone model to improve the computational efficiency. In the reduced model, spray penetration and air entrainment are calculated for a number of zones within the spray while three zones with aggregated spray zone concept are used for the calculation of spray combustion and emission formation processes. It is also assumed that liquid phase fuel appears only near the nozzle exit during the breakup period and that spray vaporization is immediate in order to reduce the computational time. Validation of the reduced model with experimental data demonstrated that the new model can predict engine performance and NO and soot emissions reasonably well compared to the original model. With the new concept of reduced model, computational efficiency is significantly improved as much as 200 times compared to the original model.

Jang Gyung Ak thought the Yang Gi was the basis of life. This is why he said doctors should emphasize on preserving Yang Gi. Before his emphasis on Yang Gi he had to study and criticize the medical concept of HaGan, DanGye and DongWon. By criticizing and overcoming their medical concept's fallacy and limitations, he made his own medicine. JangGyungAk found the importance of YangGi in the theory of changes. In the "the Book of Changes" it is said the rising movement of YangGi is expressed by recipricals and propels heaven and earth, yin and yang to change. The phenomenon of life is also a reciprocal and is lead by YangGi, and so medicine should value Yang Gi. Because the phenomenon of life is lead by this Yang Gi, it is right to base changes of diseases and organize pattern identification. The pattern identification JangGyungAk presented as two Gang six Byun sets its base on YangGi.

The purpose of this study is to clarify the concept and construct of the problem recognition stage in consumer decision making process of apparel Purchase. This study was supplemented by the theoretical study and field interviews. 40 women were interviewed on their apparel purchase situation to identify problem recognition process. As a result, the concept of problem recognition in apparel purchase is the perceived difference between the ideal state of apparel affairs and the actual situation sufficient to arouse and activate the decision making process. And the problem recognition stage in apparel purchase is constituted of the following steps: gestation, categorization, problem definition, and purchase intention formation. In most cases, these four steps existed, but in some cases several steps were deleted or condensed.

Chaotic dynamics have been studied by many researchers in the fields of biology, physics, and engineering. Interest in chaos is also expanding to the social sciences such as politics, economics, and others, including the prediction of societal events. The concept of leisure has developed from a passive concept correlated with relaxation, entertainment, and ideology formation into a positive concept that assumes a more active role. As information and communications technology develops, digital leisure activity is expected to continue spreading. This expansion of digital leisure function correctly, as well as. Traditional leisure activity functions correctly more, whereas digital leisure activity is predicted to function incorrectly more often. In this paper, we propose a mathematical addiction model of digital leisure that deals with its dysfunctions such as addiction to digital leisure, including computer games, internet search, internet chatting, and social media. Herein, to solve addiction to digital leisure, we propose a model derived from a nicotine addiction.

Since nursing has come of age both as a profession and as a scholarly discipline, there has been increasing concern with delineating its theory base. In 1978 Chinn and Jacobs asserted that “the development of theory is the most crucial task facing nursing today.” The basic building blocks of theories are concepts. Concept formation begins in infancy, for concepts help us to categorize and organize our environmental stimuli. Concepts help us to identify how our experiences are similar or equivalent by categorizing all the things that are alike about them. concepts can be primitive, concrete, or abstract. Concept Analysis is a strategy that examines the attributes or characteristics of a concept. It is a formal, linguistic exercise to determine those defining attributes. It encourages communication. Its basic purpose is to distinguish between the defining and irrelevant attributes of a concept similarities. It is a process of determining the differences between concepts and it is useful for several reasons. It is an excellent way to begin examining information in preparation for research or theory construction and results in an operational definition and a list of defining attributes and antecedents. It provides the scientist with an excellent beginning for a new tool, is an excellent way of evaluating an old one and is useful in evaluating existing instruments. The steps of concept analysis are : 1. Select a concept, 2. Determine the aims or purposes of the analysis, 3. Identify all uses of the concept that you can discover, 4. Determine the defining attributes, 5. Construct a model case, 6. Construct borderline, re-lated, contrary, invented, and illegitimate cases, 7. Identify antecedents and consequences, 8. Define empirical referents. In this paper, the concept selected for analysis was Love. The concept of love is of great interest to nursing because loving care is considered vital to the nursing care of patients. The aims of the concept analysis of love were to clarify the meaning of love, to develop an operational definition for it and to contribute to existing nursing theory. Love influences the quality of life which is the goal of nursing according to Parse in her Human Becoming Theory. Lived experiences are the entities for study in Parse's Research Methodology. Human caring, human understanding, and human becoming are the most important issues in lived experiences. In this research, dictionaries and literature from nursing philosophy and other human disciplines were used to identify the concept of love. As many different instances of the concept as could be found were examinned. The model case was a real life example of the use of the concept. Next borderline, related, invented, and contrary cases were constructed for the purpose of providing examples of “not the concept” and for promoting further understanding of the concept being discussed. The defining attributes of the concept of love were concern, responsibility, respect, understanding and dedication. Love was defined as showing concern and understanding. relating with mutual respect and dedicating oneself responsibly to others. Concept analysis is a highly creative activity and may add significant new information to a given area of interest. It is a strategy for developing a concept based on observation or other forms of empirical evidence. The purpose of concept analysis is to generate new ideas. It provides a method of examining data for new insights that contribute to theoretical development. This concept analysis suggests that a nurse’s love for patients is shown in the process of giving oneself in mutual relationships of responsibility and respect and in continuously providing understanding and quality human care for them.

In this paper we introduce three kinds of theory on the origin of the world, the formation theory, the emanation theory and the creation of nothing. Especially through Augustinus, great scholar of patristic philosophy in the Middle Ages, how the relationship between the God and the creature was shown with the concept of the infinity and the finite.
