국내에서 석회석 산업은 대규모의 시장이 형성되어 있는 국가적 기간산업이고, 석회석의 부존자원으로서의 잠재성도 크다는 것은 주지의 사실이다 그러나 값싼 소재자원으로서 대규모 개발 및 수요 특성을 가졌던 종래의 석회석 산업에서는, 품위 및 품질 개념의 인식이나 구분도 없이 단순히 화학분석 자료에만 의존하여 개발과 가공이 이루어질 수 밖에 없었다. 최근에 대두되는 환경문제와 생산원가의 상승으로 인해서 국내 석회석 산업계에는 국내 석회석 자원의 효율적 개발과 부가가치의 증진이 절실히 요구되는 상황이다. 이를 위해서는 종래의 화학분석치 일변도의 석회석 평가방식을 지양하고, 보다 합리적인 응용광물학적 광석평가 방식이 적용되어야 할 것이다. 석회석의 광물상, 광물조성 및 광물특성을 그 용도별로의 품위 및 품질 개념을 적용해서 평가함으로써, 우리의 소중한 자연의 기반물질이자 부존자원인 국내산 석회석을 효율적으로 개발 및 가공하는 지혜가 필요할 것으로 여겨진다. 이에 따라 석회석에 대한 새로운 관점에서의 평가 개념을 국내산 주요 고품위 석회석을 대상으로 논의하였다. 또한 이를 토대로 국내산 석회석의 효율적 개발과 부가가치 제고를 위한 새로운 광물특성 평가방안을 제시하였다.

본 연구에서는 추상적 사고를 가능하게 해주는 개념은유 표현의 서술어를 분석하여, 추상개념의 근원영역을 찾는 알고리즘을 HowNet 지식 시스템을 이용하여 제안하고자 한다. 실제로 추상개념 '문화' 가 쓰인 242개의 은유 표현 용례 문장을 가지고 제안된 알고리즘으로 근원영역을 찾고. 이를 토대로. 목표영역 '문화' 의 근원영역이 추론기에 의하여 자동적으로 추론되는 HowNet 기반 은유 온톨로지의 구축 방안을 제시하고자 한다. 또한, 한국어 '문화' 와 영어표현 'Culture'의 근원영역 비교를 통하여 구축된 온톨로지를 영어 번역 및 작문에 어떻게 활용할 수 있는지 보이고자 한다.

In Hegels Wissenschaft der Logik wird die Idee als Leben des Begriffes, objektive Vollendung und Einheit von Subjekt und Objekt bezeichnet. Die Idee ist die Einheit von Begriff und dessen Existenz und des weiteren die "allgemeine Bedeutung des wahren Seins". Die Idee ist nicht die Namensgebung einer Abstraktion der Sache als abstrakte Sache oder einer reinen Form, sondern 'das Werden zum Diesem' oder 'das Diese' des konkreten und realistischen Objektes 'Dies hier und jetzt'. Auf einer solchen logischen Bestimmung beruhend, behauptet Hegel in seiner ${\ddot{A}}sthetik$ die Gleichheit zwischen "$Sch{\ddot{o}}nheit$" selbst und der "Idee der $Sch{\ddot{o}}nheit$". "Das $Sch{\ddot{o}}ne$ selbst" ist gleichzusetzen mit der "Idee der $Sch{\ddot{o}}nheit$" und wenn die Idee in einer bestimmte Form hineinpasst, wird dies das Ideale genannt. Hier liegt der Grund, weshalb wir die Idee als Begriff, Begriff des Daseins oder Einheit des Objektes bezeichnen $k{\ddot{o}}nnen$. Die Idee ist die Einheit von Begriff und dessen $Realit{\ddot{a}}t$, jedoch ist die dominierende Kraft der Einheit der Begriff. Die Idee ist die $Totalit{\ddot{a}}t$ der subjektiven Bestimmung und nur das Werk dass mit dem Begriff passend Einheit und $Objektivit{\ddot{a}}t$ hervorbringt, ist wirklich $sch{\ddot{o}}n$. Umgekehrt gesagt bedeutet diese Aussage, dass etwas wirklich $sch{\ddot{o}}n$ ist, wenn dies zu dem Begriff passt, und dass das genau zum Begriff passende ist mit dem Begriff gleichzusetzen ist. Wie bereits $bewu{\beta}t$, hat Kant die $f{\ddot{u}}r$ den kognitiven Begriff verantwortliche bestimmende Urteilskraft und das ${\ddot{a}}sthetische$ Urteil treffende reflektierende Urteilskraft, differenziert. Im Gegensatz dazu $erkl{\ddot{a}}rt$ Hegel die Beziehung zwischen Sein und Denken, Dasein und Begriff, Begriff und Idee mit dem Blickpunkt dass das $Verm{\ddot{o}}gen$ und die Funktion der Urteilskraft selbst eine grundliegend auf Reflektion beruhende Bestimmung ist und eine auf Bestimmung beruhende Reflektion ist. Nach dieser Logik entsprechend $f{\ddot{u}}hrt$ er die Beziehung zwischen der $sch{\dodt{o}}nen$ Sache und $Sch{\ddot{o}}nheit$ zusammen. In dieser $Erkl{\ddot{a}}rung$ verwirft Hegel Kants Begriffe wie Urteilskraft und Geschmack, und verwendet vorwiegend die von seiner Lehre vom Begriff auftauchende Begriffe. Die Zielsetzung dieser Arbeit ist, den Satz in Hegels ${\ddot{A}sthetik$ "Das $Sch{\ddot{o}}ne$ ist die Idee des $Sch{\ddot{o}}nen$" auf den Grund zu gehen. Um dieses Ziel zu verfolgen, wird das epistemologische $Verh{\ddot{a}}ltnis$ zwischen Dasein und Begriff, das logische $Verh{\ddot{a}}ltnisas$ zwischen Begriff und Idee betrachtet.

The notions of conditional probability and independence are fundamental to all aspects of probabilistic reasoning. Several previous studies identified some misconceptions in students' thinking in conditional probability. However, they have not analyzed enough the nature of conditional probability. The purpose of this study was to analyze conditional probability and students' knowledge on conditional probability. First, we analyzed the conditional probability from mathematical, historico-genetic, psychological, epistemological points of view, and identified the essential aspects of the conditional probability. Second, we investigated the high school students' and undergraduate students' thinking m conditional probability and independence. The results showed that the students have some misconceptions and difficulties to solve some tasks with regard to conditional probability. Based on these analysis, the characteristics of reasoning about conditional probability are investigated and some suggestions are elicited.

In this study, we identified the conceptions of heat and temperature on a basis of the science history, and analyzed the explanation types in elementary, and secondary school science textbooks. From these data, we tried to discover the cause of students' misconceptions. The results revealed that the explanation types of the textbooks don't include modem sight. Different conceptions developed in different era mixed in the textbooks. We can infer that students who learn heat and temperature concept by the textbooks could have misconceptions because of the above problems.

이 글에서 필자는 결정론적 인과를 토대로 속성 수준의 인과와 사건 수준의 인과의 연관성을 주장하는 하우스만(Hausman 1998)의 이론을 비판하고 두 수준의 인과의 관계를 바르게 이해하는 데 무엇이 필요한지를 제시한다. 하우스만은 결정론과 배경 조건의 다양성을 토대로 그리고 비결정적 상황에서는 확률에 대한 결정론적 인과를 토대로, 속성 수준의 인과는 사건 수준의 인과에서 도출된다는 의미에서 속성 수준의 인과는 사건 수준의 인과의 일반화라고 주장한다. 필자는 그 관계에 대한 문제를 제기하고 이 문제는 사건 수준의 인과에 본질적인 인과 연결을 주목하지 않은 채 변수들 간의 의존 관계만으로 두 수준의 인과의 관계를 단순히 해명하는 데에 있다고 지적한다. 필자는 두 수준의 인과의 관계는 단순히 한 가지 관점이나 방식으로 파악될 수 없고 해명, 설명, 예측 둥 다양한 관점에서 복합적으로 파악되어야 한다고 주장한다. 특히 사건 수준의 인과는 속성 수준의 인과에 개념적으로 의존하는 관계를 주목한다.

The software pattern is knowledge representation derived from the verified solutions or the experience of the experts. On account of the design varieties of software development, however, it is not the facilitated task to discover the best proper software pattern. This situation requires that software patterns be categorized in terms of their innate concepts. This paper proposes software pattern ontology(SPO) for the systematic categorization of software patterns by means of conceptual properties of patterns after the comparative analysis of association between software pattern and ontology. The SPO presented in this paper can establish the basis for the software pattern management system at the conceptual level. This paper also shows an idea for the application by unifying conceptual properties of software pattern and ontology.

This paper provides an analysis of a survey on high school students' understanding of definite integral. The purposes of this survey were to identify high school students' private concept definitiones and concept images on definite integral. Definitions and images, as well as the relation between them of the definite integral concept, were examined in 108 high school students. A questionnaire was designed to explore the cognitive schemes for the definite integral concept that evoked by the students. The students' individual answers were collected through written environment. Four types of the private concept definitiones and concept images were identified in the analysis.

Two conceptually thorny issues in IT governance definition and understanding are examined and discussed. It is argued that the traditional IT governance definition, which defines governance in terms of the content of enterprise IT activity, is prone to logical inconsistency and indeterminacy. A new objectives-bound definition of IT governance is proposed as a remedy to the problem. It is proposed that the essence of the objectives-bound IT governance lies in making enterprise IT activity explicit, formal and subject to external scrutiny in its effort to achieve the effectiveness, transparency and accountability of IT. A conceptual apparatus called IT activity axes is employed to characterize and distinguish the different approaches to IT governance definition and understanding. It is suggested that IT governance can be defined using a simple frame of reference with logical consistency and coherence. The theoretical and practical implications of the IT governance definition are discussed at the end.
