Objectives : The concepts of many Korean medicine terms have changed for a long time and cumulatively been recorded in later medicine literatures. And, the same terms have very often been used for different meanings depending on context. Methods : This study was performed so that conceptual magnitude of Korean medicine terms could intuitively be recognized for the purpose of quantization. Results : This study was performed under the premise that terms used in old literatures of Korean medicine are related mostly to treatments that could immediately be reverted to types of medical herbs used. Through this, conceptual magnitude of terms was quantified by the method that frequency of medical herbs used for treatment was changed to numerical values. For this, data of "Compilation of Formulas and Medicinals Addendum" were used. First, after 'specificity' of each medicine herb corresponding to representative disease symptoms was calculated, medians in the set were selected, and 'values of conceptual magnitude' for representative disease symptoms were calculated. Conclusions : As a result, if disease symptoms are diverse, concept range is diachronically changed greatly, and specific disease symptoms of great conceptual difference are included, value of conceptual magnitude was great. Meanwhile, if disease factor and treatment are singular or limited to several types, and many medical herbs with high specificity are used, value of conceptual magnitude was less.

IT environment gets more complicated in terms of open platform, network standards, device design and hardware, etc. Smart network and application are in the fields of corporate as well as national competition for future fusion technology. In development environment focused on computers, the ideas of authoring tool have been presented in terms of improved software productivity. In smart environment where subdividing works are consecutively done, current authoring tool should be effectively updated for effective development of programs and easier access to business works. The basic concept of a new conceptual App development tool, Smart App Authoring Tool, which has been designed in this study and enables to apply on-site requirements to smart phones, is to develop Apps on the level using easy-to-learn Word or Excel in a computer. Therefore, this study is intended to design a conceptual Smart App Authoring Tool to optimize the cost and time for developing and maintaining new application services under various smart phone platform environments. Based on the performance of smart app authoring tool herein, every people can develop a smart app program at moderate level. So this paper have designed a conceptual smart app authoring tool. This study presented educational efficiency of the authoring tool by developing business Apps under various business environments and applying them under university and high school environments.

Recently we have seen a noticeable trend in ports to establish port clusters. Despite this trend, little research has actually been undertaken to fully define and analyse port clusters. A couple of exceptions have descriptively defined port clusters but the boundaries of port clusters are not apparent. Therefore, the aim of this paper is to define port clusters in terms of set theory and in particular look at them in terms of their distinct characteristics and system boundaries. The main concern of this paper is that there is a need to distinguish, from a system and a competition perspective, between port clusters, ports, maritime clusters and port ranges. This paper proposes a conceptual model relevant to the relationship among port clusters related assemblages and that has been applied to the north western europe region This model suggests six levels of competition that will help port authorities and government to develop appropriate policies and strategies for port operation and port industry.

기하학의 기본용어인 점과 선에 대한 유클리드의 사전적 정의에서 힐베르트의 수학적 정의 개념으로의 변화과정을 살펴보았다. 이러한 수학에서의 정의 개념 변화의 인식론적 배경은 바로 수학적 대상의 존재 방식에 대한 실재론, 개념론을 거쳐 유명론에 도달하는 철학적 인식의 변화이다.

The purpose of this study is to develop a method of applying response surface analysis to trade-off techniques for the conceptual design of armored vehicle. The problem areas of concern are the use of this method in the selection of optimum design points when user requirements are in conflict. The application of this method to trade-offs of performance parameters in terms of weight are presented.

본 연구의 목적은 수학 문장제 해결에 기초가 되는 수학과 용어의 유형에 따른 한국어학습자의 이해 특성 및 오류유형을 파악하여 한국어학습자의 문장제 해결에 효과적인 교수·학습 지도 방안 마련을 위한 기초 자료를 제공하는 것이다. 이를 위해 학교에서 별도의 한국어 수업을 듣는 한국어학습자 4명을 대상으로 교육과정 등재 용어와 교과서에 사용된 교육과정 미등재(정의/무정의) 용어에 대한 구체적인 개념이미지를 분석하는 사례 연구를 하였다. 연구 결과 첫째, 한국어학습자가 수학과 용어에 대하여 적합한 개념정의를 정립할 수 있도록 충분한 시각화 자료를 활용하여 지도할 필요가 있다. 둘째, 한국어학습자의 가정 내 사용 언어와 수학과 용어에 대한 적합한 개념이미지 형성 사이의 구체적인 관계를 파악할 필요가 있다. 셋째, 능동형 용어보다 의미 이해에 어려움을 겪고 있는 피동형 용어에 주의하여 지도할 필요가 있다. 넷째, 일상의 의사소통에 어려움이 없는 한국어학습자의 경우에도 수학 교과서에 사용되는 교육과정 미등재 일상어에 대하여 지도할 필요가 있다. 다섯째, 용어에 대한 설명에서 나타난 한국어학습자의 언어적 특성이 반영된 오류 유형을 고려하여 수학과 용어를 지도해야 할 것이다. 이러한 인식은 언어적 배경이 다른 한국어학습자의 문장제 해결 지도에 도움이 될 것으로 기대된다.

The purpose of this study was to investigate the effects of using graphing calculators on students' understanding of the linear and quadratic function concepts. The populators of this study are tenth graders at high school in Seoul, one class for the treatment group and another class for the comparison group, and experiment period is 14 weeks including two weeks for school regular exams.Function tests used in the study was proposed which described a conceptual knowledge of functions in terms of the following components: a) Conceptual understanding, b) Interpreting a function in terms of a verbal experission, c) Translating between different representations of functions, and d) Mathematical modeling a real-world situation using functions. Even though the group test means of the individual components of conceptual understanding, interpreting, translating, mathematical modeling did not differ significantly, there is evidence that the two groups differed in their performance on conceptual understanding. It was shown that students learned algebra using graphing calculators view graphs more globally. The attitude survey assessed students' attitudes and perceptions about the value of mathematics, the usefulness of graphs in mathematics, mathematical confidence, mathematics anxiety, and their feelings about calculators. The overall t-test was not statistically significant, but the students in the treatment group showed significantly different levels of anxiety toward mathematics.

A successful, computer-aided design support system can help a process designer focus on making effective design decisions, not merely tedious routine calculations. Such a system is essential to enhance quality of design in terms of economics, environmental benignity, reliability, robustness, and operability. Such a statement is even more accepted when applied to conceptual design problems, where gross design specifications are given while a combinatorial number of design alternatives exists. This paper presents an agent-based approach as a systematic and efficient way to design a design support system for the synthesis of conceptual chemical processes. An agent-based approach allows us to handle design knowledge as an object and thus greatly improve the modularity and reusability of that knowledge. Such modularity and reusability lead to the increased productivity in the development of a design support system and the increased ease in the relaxation of design decisions and the generation of design alternatives, both of which functions are critically important in dealing with the complexity and uncertainty of conceptual design problems.

이 논문에서는 초등학교 교과서에서의 가분성(divisibility) 개념을 중심으로, 개념적 사고의 과정을 그대로 Python 언어로 코딩하고 Computational Thinking (이하, CT) 중 하나인 자동화에 따른 계산의 효율성을 고찰하였다. 이로부터 얻을 수 있는 교육적 시사점은 다음과 같다. 수학적인 개념적 사고를 CT의 관점에서 생각해 보고, 또한 역으로 컴퓨터 과학에서 중시하고 있는 CT에서 수학적 개념을 추출해 볼 수 있는 쌍방향의 활동이 수학 중심의 코딩교육에서 필요하다.
