본 연구에서는 수리철학의 사상과 과제를 분석하기 위하여 수리철학과 형이상학의 내용의 조화적인 유형의 분석을 중심으로 살펴보기로 한다. 형이상학과 수리철학의 논쟁적인 의문은 특히 수학적 추상의 본질과 관련하여 수리철학적 입장에서만 가능함을 알 수 있다. 따라서 이러한 태도는 미래의 철학에 대한 수학의 관계에 있어서 명백한 영향력을 가지게 될 수 있고 많은 연구가 미래에 큰 의미를 부여할 수 있기를 기대한다. The purpose of this paper is to analysis with contents on thoughts and problems of philosophy of mathematics concerning around harmonical types of metaphysics and philosophy of mathematics. Moreover, we were gratefully acknowledged that the questions at issue of metaphysics and philosophy of mathematics are possible only in a philosophical position of mathematics in relation to nature of mathematical ion. These attitudes, important as they are in the study of an individual thinker, also have a pronounced effect on the future relation of mathematics to philosophy. And we can guess that many mathematician's research will have significant meaning in the future.

By using the notion of interval-valued intuitionistic fuzzy relations, we form the poset (IVIR(X), $\leq$) of interval-valued intuitionistic fuzzy relations on a given set X. In particular, we form the subposet (IVIE(X), $\leq$) of interval-valued intuitionistic fuzzy equivalence relations on a given set X and prove that the poset (IVIE(X), $\leq$) is a complete lattice with the least element and greatest element.

As the advent of the Internet, B2B negotiation process on the Internet has been given attention from both researchers and practitioners. However, literature still shows that only structured conditions have been explicitly considered, despite the fact that unstructured conditions should be rendered as well. In this sense, this paper proposes a new negotiation support mechanism to incorporate causal relationships between structured and unstructured conditions in the process of B2B negotiation. Fuzzy cognitive map was used as a main source of causal knowledge as well causal inference engine. A prototype named CAKES-NEGO was developed to perform experiments with an illustrative example. Results revealed the robustness of our proposed negotiation support mechanism.

Knowledge management has been drawing a great deal of attention from researchers and practitioners since a few years ago. The underlying reason for this phenomenon is that traditional management principles has neglected the importance of the fifth management source named knowledge with which a modern business firm can cope with turbulent environment with a high level of competence and effectiveness. Therefore, as Drucker noted, most of modern business firms realized that they are performing daily managerial activities in a so called knowledge society where knowledge-intensive firms can excel those capital-intensive firms, and be highly evaluated in the market. However, the remaining problem is that there do not exist robust methods for precisely and objectively measuring the amount of intellectual capital or knowledge which is believed to be tacitly stored in the management process, personnel power, and customer relationship which the firm has struggled to obtain in the market.

본 연구의 목적은 인터넷비즈니스 과목에서 교수-학습모형의 개발하였다. 이를 위하여 교수-학습 방법에 대한 기존문헌 연구를 통하여 교수-학습에 사용되는 주요한 변수를 도출하고 이를, 실제 인터넷비즈니스 수업을 수강하였던 학생들을 대상으로 설문을 실시하였다. 또한 이 요인들간의 인과관계를 구조등식모형으로 설정하고 실제적으로 설문을 통하여 분석하고 증명함으로써 교수-학습에 대한 새로운 인과모형을 제시하였다. 이렇게 도출한 인과모형을 중심으로 교수자와 학습자들의 인지지도를 작성하게 하였으며, 이를 반영하여 최종적인 교수-학습모형 (Cognitive Instruction-Learning Model: CILM)을 개발하여, 다양한 문제를 시뮬레이션을 통하여 해결방안을 제시하였다. The objective of this study is to propose the cognitive instruction-learning model for the “Internet Business” class which is currently being lectured in many universities. It is well known that students have different view from instructors in the class, causing unexpected inefficiency in communication between students and instructors. However, the previous studies fail to show concrete and unified resolution results on this issue. To fill the research void like this, this study proposes applying the cognitive map to coordinate different views of both instructors and students, and derive an effective education paradigm. The cognitive map is induced from statistical results using LISREL and 596 valid questionnaires from active students studying the Internet business subjects. Four scenarios are conducted to show how effective the proposed cognitive instruction-learning model is for the “Internet business” class. The results reveal that the proposed education mechanism is valid and robust for teaching the Internet business. Besides, we find that the results of this study can be easily extended to other similar research issues.
