  • 본 연구는 증명을 성공적으로 구성하는 학생들은 수학적 개념을 어떻게 이해하고 있으며, 증명을 어떻게 구성하는 지를 살펴보고 이를 통해 증명을 구성하는 다양한 방식과 개념 이해의 관련성을 분석하는 데 목적이 있다. 증명 구성에 도움이 되는 수학 학습에 제언을 얻기 위해서는 증명을 구성하는 과정과 그 과정에서 개념이 어떻게 반영되고 이용되는 지를 살펴볼 필요가 있다. 이를 위하여 4명의 수학교육과 학생들을 대상으로 사례연구를 실시하였다. 그 결과 구문론적 증명을 하는 학생들은 형식적 개념의 내용을 정확하게 알고 있을 뿐만 아니라 그 개념이 담겨있는 명제는 어떠한 방식으로 증명하는 지 그 방법까지 알고 있었다. 실제 증명에서도 평소 증명 경험을 통하여 학습한 증명 전개 방법을 이용하여 증명하는 것을 볼 수 있었으며, 이로부터 증명 방법에 대한 절차적 지식이 구문론적 증명에는 중요한 요소라는 결론을 얻을 수 있었다. 의미론적 증명을 하는 학생들은 형식적 개념의 내용을 정확하게 알고 있고 그 내용과 의미를 본인만의 언어나 그림으로 표현한 개념 이미지를 가지고 있었다. 구문론적 증명을 하는 학생들의 개념 이미지와 비교해보았을 때, 의미론적 증명을 하는 학생들의 개념 이미지는 구문론적 증명을 하는 학생들의 개념 이미지보다 형식적 개념의 내용을 잘 반영하고 있었다. 이러한 개념 이미지는 개념 이미지를 활용하여 증명의 아이디어를 생각하고, 생각한 아이디어를 증명의 형식에 맞게 표현하는 데 사용된다는 점에서 의미론적 증명에 필요한 요소라는 것을 발견할 수 있었다.

  • To easily understand and systematically express the behaviors of the industrial systems, various system modeling techniques have been developed. Particularly, the importance of system modeling has been greatly emphasized in recent years since modern industrial systems have become larger and more complex. Multilevel flow modeling (MFM) is one of the qualitative modeling techniques, applied for the representation and reasoning of target system characteristics and phenomena. MFM can be applied to industrial systems without additional domain-specific assumptions or detailed knowledge, and qualitative reasoning regarding event causes and consequences can be conducted with high speed and fidelity. However, current MFM techniques have a limitation, i.e., the dynamic features of a target system are not considered because time-related concepts are not involved. The applicability of MFM has been restricted since time-related information is essential for the modeling of dynamic systems. Specifically, the results from the reasoning processes include relatively less information because they did not utilize time-related data. In this article, the concepts of time-to-detect and time-to-effect were adopted from the system failure model to incorporate time-related issues into MFM, and a methodology for enhancing MFM-based reasoning with time-series data was suggested.

  • The purpose of this study is to present the cognition of speculative aesthetics in the architectural space. Architectural space as the subject of the aesthetical study has been ignored such a long period though it should be centered of the whole architectural theory. Even it has not been dealt with independently but just only as a part of aesthetic or artistic field. Also it is also true that academic approach to the architectural space as per the aesthetic recognition has not been done so satisfactorily. The transcendental subjectivity as the aesthetic cognitive viewpoint of the architectural space means speculative aesthetics and the understands the essential meaning of the function and composition The conclusions of this study are as follows : The formalistic cognitive concepts including organic functional space between the whole and the part and anti-cubic synchronous space are included in the architecture of the speculative cognition, and finally the contextual cognitive concepts including the restoring analogical space of the in-depth constituent factors and associated centripetal spaces.

  • In this paper, design measure were proposed for the construction of terminal systems for airborne platforms, which are key element in the Joint Tactical Data Link System (JTDLS) complete system. The Korean perfect tactical data link (JTDLS) is a communication system to establish an independent tactical data link network and needs to develop a MIDS-LVT (Link-16) communication terminal for datalink. Once a Ground/Navy JTDLS terminal system is established around airborne platform, it will be possible to break away from reliance on NATO-based tactical data link joint operations and establish independent Korean surveillance reconnaissance real-time data sharing and tactical data link operations concepts. in this paper, the essential development elements of airborne platform mounting and operable JTDLS terminals are presented, and the concept of system design is proposed to embody them. Further, improved system performance was analyzed by applying the concepts of complex relative navigation system and Advanced TDMA protocol for the deployment of airborne tactical datalink networks.

  • Future-oriented train design should be able to provide highly refined traffic culture and public transportation service by achieving 'higher value addition, sensitization, and humanization' and then securing safety, convenience, and amenity. Therefore, design of FRT, as a means of environment-friendly public transportation, should have new concepts achieving harmony between design and technology. Consequently, when designing interior of trains for public transportation, it should aim for user-centered strategies. This approach is essentially applied to vehicle design and inducement to new concepts by design aesthetics and their verification become requirements for train Interior design, which should be equipped with sensitivity and functional images. Accordingly, a study on the correlation between constituents in order to implement design is essential to design planning and realization of strategies.

  • Facing the issue of global climate change, it is important for environmental educators to prepare a person who is able to understand of, communicate about, and make informed decisions on the climate change. Climate change education is to help learners understand of human influence on climate and climate's influence on them and society. This study was conducted in a way to discuss how climate change education could be implemented in Korean context. For this purpose, several documents and research articles on climate change education and communication were analyzed: Climate literacy, guidelines for K-12 global climate change education, and guidelines for effective climate change communication and message and so on. Many of the documents emphasize age appropriateness, positive thinking, participation and empowerment in climate change education while suggesting not to burden young learners with fears. Some documents such as the climate literacy suggest key concepts and/or essential principles of climate change education. Based upon the analysis, several considerations to incorporate the concepts in climate change into educational programs were suggested for further discussions.
