This paper was designed for the purpose of helping the functional comprehension on the concept of a circumcenter and an incenter of triangle and offering the help for teaching-learning process on their definitions. We analysed the characteristic of the definition on a circumcenter and an incenter of triangle and studied the context, mean and purpose on the definition. The definition focusing on the construction is the definition stressed on the consistency of the concept through the fact that it is possible to draw figure of the concept. And this definition is the thing that consider the extend of the concept from triangle to polygon. Meanwhile this definition can be confused because the concept is not connected with the terminology. The definition focusing on the meaning is easy to memorize the concept because the concept is connected with the terminology but is difficult to search for the concept truth. And this definition is the thing that has the grounds on the occurrence but is taught in a made-knowledge. The definition focusing on both the construction and meaning is the definition that the starting point is vague in the logical proof process. We hope that the results are used to improve the understanding the concept of a circumcenter and an incenter of triangle in the field of mathematical education.

There are many definitions around brand. It complexify academic literature. Thus, this study collected meaningful definitions among many statements about brand and analyzed and classified them by available perspectives. This is especially necessary contents in domestic brand study, which is short of concept research about brand. Various literatures are refereed to brand definition introduction. But to etymological definition, several European linguistic theses are deeply reviewed and to institutional definition, wide range of information such as history, law and society is refereed. Total brand definitions are classified in . It is divided into 2 parts which are non-commercial context (etymological and institutional definition) and commercial context (producer, customer and the relation or interaction between producer and customer). In etymological definition, the word origin is clear word 'brandr' which means 'burning wood' and cattle-brand made this 'brand'. In legal definition, legal and institutional meaning of 'trademark' is examined. Etymological definition and institutional definition are fundamental and lexical definition which show brand history. These are foundation stones in brand studies.

형식개념(Formal Concept)은 외연(extent)과 내포(intent)를 이용하여 어떤 대상에 대한 정의를 내리거나, 그 대상들을 분류하여 군집화하기 위한 논리적 도구로 사용되어왔다. 여기에서 외연이란 객체(Object)들의 집합이고, 내포는 그 객체들이 지니고 있는 속성(Attribute)들의 집합이다. 이러한 형식개념은 어떤 문제에 나타나는 다양한 데이터로부터 객체와 속성들을 추출하고 이로부터 개념(Concept)들의 계층구조(hierarchy)를 형성하여 데이터를 분석하는데 적용될 수 있다. 본 논문에서는 형식개념의 정의와 성질을 소개하고, 이를 일반화한 완비격자에서의 형식개념을 정의한다. 또한 이 형식개념에서의 외연과 내포격자에 대한 성질을 알아본다.

The purpose of the study was to investigate the definitions and concept images of Infinity and limits for high school students. In addition, the error patterns of the students were also investigated. The participants were 121 girls highschool students and survey method was used to co11ed data. Only 11 % and 5% of the participants revealed the definitions similar to the standard textbook definitions in limits of infinite sequences and infinite series respectively. The participants showed 6 types of error patterns and had more difficulties in understanding and applying concepts and properties of infinite series than those of infinite sequences.

This paper examines how Nietzsche, criticizing anti-naturalist philosophies, reformulated concepts of nature and human nature, and revaluated them from the perspective of naturalism. Especially, it focuses on his task for naturalistic ethics to naturalize nature and to place man back into nature. This paper also tries to reinterpret his attempt to transfer the concept of justice from the metaphysical realm to the naturalistic one, which seems to give some important insights to develop theory of environmental justice, while pointing out some limitations in his naturalistic concept of justice.

This study aims to explore the concepts and nature of records in digital environments based on analyzing recent theoretical studies of records. This is not intended to defining records for management in a specific environment. This study is divided into two parts. Firstly, it classifies the definitions of records in three perspectives; evidence, information, and representation of activities, and explores the concepts and theoretical backgrounds underlying each definition. Secondly, it articulates some implications for understanding the concept and nature of records in digital environments by four categories such as i) fixity, ii) materiality, iii) activity and context, and iv) trustworthiness, which were derived from the definition of "persistent representation of activities" by Geoffrey Yeo.

The concepts of entrepreneurship are very various. So many researchers are confused or not sure of the concepts of entrepreneurship. Some entrepreneurship researches has defined the entrepreneurship as 'self-employment. This study try to set a comprehensive conceptual model of concepts of entrepreneurship through classification of word and phrase with job analysis and competence model. Several concepts of entrepreneurship which important prior researchers, had defined are analysed into 'subject', 'object', 'verb', 'goal and behavioral results' with content analysis. Also, Several concepts of entrepreneur which important prior researchers had defined, are analysed into 'individual psychological traits', 'competence and ability', 'motive', and 'function or job (business).' This study suggests a integrated conceptual model of entrepreneurship based on analysed results.

일상생활에서 우리가 정하는 대상중에 명확하게 그 소속을 정의 할 수 없는 경우가 많다. 이러한 대상들을 수학적으로 다루기 위하여 퍼지집합의 개념을 도입하였다. 이 퍼지집합 개념은 각 대상이 속한다, 안속한다라는 이원론적인 논리오부터, 각대상을 그 모임에 속하는 정도로 이해함으로써 일반화된 개념이다.

지식 정보의 확산에 따라 기존 전문분야 용어집에 수록되지 않은 용어의 수가 폭발적으로 증가하고 있다 이에 따라 용어집을 자동으로 구축하는 작업이 필요하게 되었다. 본 논문에서는 의학분야 코퍼스에서 주어진 전문용어에 대한 정의문을 자동으로 추출하는 방법을 제안한다. 우선, 정의문의 구문적 패턴과 용어의 어휘구성 패턴을 이용하여 용어의 상위개념을 추정한다. 상위개념별로 구축된 특성 어휘 목록을 이용하여 구문적 패턴으로 뽑힌 문장에 등장하는 어휘의 적합성 여부를 판단하여 정의문을 추출한다. 실험 결과 코퍼스에 정의 정보가 있는 48개의 용어에 대하여 71.43%의 정확률을 보인다.

객체와 객체, 객체와 환경(공간 객체) 사이의 상호작용을 Field 라는 개념을 도입하여 개념적으로 장 이론이라는 방법론으로 객체들간의 상호작용을 해석하였다. 구체적으로 환경은 공간에 대한 수학적 개념으로 정의하고 객체와 환경사이의 상호작용은 해석하였다. 구체적으로 환경은 공간에 대한 수학적 개념으로 정의하고 객체와 환경사이의 상호작용은 일련의 상호 의존적 사실들로 표현하였다. 따라서 공간에 대한 수학적 개념과 힘의 역동 개념을 동원해서 객체와 환경이 주어진 상황에서 나타나는 구체적인 행동을 기술한다. Vector, Algebra, Topology 등과 같은 물리학적 및 수학적 개념을 도입하여 객체 상호작용을 해석하기 위한 과학적 이론 시스템 개발에 활용할 가능성을 제시하였다.
