This paper presents multi-fidelity modeling and simulation (M&S) methodology to enhance simulation performance of engineering-level defense models. In this approach, a set of models with varying degrees of fidelity is exercised to reduce computational expense maintaining a similar level of system effectiveness. For multi-fidelity M&S principles, this paper defines model fidelity from two perspectives (i.e., model behavior and execution), and suggests the Fidelity Change Point (FCP) to specify the fidelity conversion. With these concepts, this paper centers on three ideas: 1) two models' structure which are the Behavioral-Fidelity Interchangeable Model (B-FIM) and the Executional-Fidelity Interchangeable Model (E-FIM), 2) modeling formalism, and 3) a simulation algorithm to support them. From an abstract case study regarding a target tracking scenario with the utilization of the proposed method, we can gain interesting experimental results regarding the enhancement of simulation performance. Finally, we expect that this work will serve various M&S-based analysis areas for enhancing simulation performance.

This study is to compare and analyse the high school chemistry curriculum in Korea and Japan from the viewpoint of the structure, objectives, contents, teaching-learning method, and assessment plans. From the comparative analysis, we found some common and different aspects. The suggestive ideas which is useful for study of Korean science curriculum were deduced, such as more expansion of selective subjects and enhancing the guidance, more flexible teaching methods, enhancing the individualized instruction plans suitable to each student's condition, careful selection of educational contents and enhancing the base and foundation, and transition period.

Currently, in the field of spinal surgery around the world, various new technologies have been rapidly developed and applied to patients. The author believes that it is necessary to discuss whether these new technologies are being fully reviewed for efficacy and safety before being applied to patients. To consider this issue, the author analyzed the basic research data and clinical application process of the intradiscal electrothermal therapy, which was developed as a new technology for discogenic pain disease in the 2000s and has been widely used worldwide. As a result, it was found that this procedure has been performed on patients in a state where there is insufficient base research on efficacy and safety. The author judges that this case reveals an essential problem related to the clinical operation of new medical technologies in the field of spine surgery. Therefore, the author believes that in order to minimize the side effects that new medical technology in the field of spinal surgery may have on patients, more full-fledged basic research and higher clinical acceptance standards should be established.

The wind force coefficient of a transmission tower frame shows several characteristics when the section shape, solidity ratio, and wind direction angle are changed. In this study, the wind force characteristics of a transmission tower frame with a basic structure were evaluated using different solidity ratios and wind direction angles in a wind tunnel test. According to the solidity ratio, the size of the structure and the rectangular-frame model of the transmission tower were changed by adding a two-dimensional (2D) or three-dimensional (3D) structure. The transmission tower's rectangular frame was tested by changing the wind direction angle of the 2D-type structure from 0 to $90^{\circ}$ and by changing the wind direction angle of the 3D-type structure from 0 to $45^{\circ}$ Based on the results that were obtained, it can be concluded that the wind force coefficient of a transmission tower frame can be used as preliminary data in deciding the transmission tower's wind load.

The development of modem technology made people more aware of the importance of science education, which was followed by research on textbooks based on the new curriculum. This study compared physics textbooks that were published after the new curriculum started in 2000 and 2002 in Korea and Japan, respectively, and aimed to become a reference for further improvement of science curriculum and textbook reform. The results were as follows : 1. The number of teaching topics in Korean science textbook is greater than those in Japan. 2. In detail, the field of physics appeared to be relatively more important in Korea's textbooks, while it was the field of biology that was given more weight in textbooks in Japan. 3. The textbooks in Korea and Japan covered in more detail the concepts of 'power and energy' and 'electricity and magnetism', respectively. 4. The textbooks in Korea introduced the contents of magnetism initially, whereas their counterparts in Japan, the contents of light. As a whole, the contents of the science textbooks in Korea and Japan were very similar. However, more detailed concepts were included in Korea's textbooks, and therefore, Korea's textbooks seemed to have richer contents than Japan.

This research was studied in regard to theatre perspective and the directing methods of the 'Theater Duke Georg II.', the ruler of the Duchy of Saxe-Meiningen in modern Germany, in his contemporary context based on the Meininger Principle. He was a theatre-cultural politician, producer and a regisseur, who used theatre as purposive media to arbitrate domestic and international reality and enhance national prestige. Especially as a regisseur, he established directing principles and methods which was performing the original texts representing playwright's perspective targeting to creat theatre as synthesis of the arts at Meningen Company. It was innovative thing itself which was that his directing art was accompanied by new theatrical aesthetics, practical principles, and staged process. He established independence and originality of directing which was breakthrough of modern stage-director's theatre. Furthermore he layed a foundation for the development of the modern and contemporary director's theatre.

섬유 패턴 디자인을 체계적이고 객관적으로 기술할 수 있는 도구를 패턴 디자인의 지각적 속성에 기초하여 개발하였다. 세 단계로 이루어진 연구의 첫 단계에서는 패턴 디자인의 단계를 실제 디자인 과정에 기초하여 'PP의 디자인', 'RPU의 디자인', 'RPU의 배열'의 순서로 개념화한 후, 이 데 영역에 걸쳐 30개의 지각적 특징들을 추출하였고, 섬유 패턴 디자인을 충실히 기술할 수 있다는 것을 확인하였다. 다음으로 추출된 30개의 지각적 특징들을 'PP의 모양에 의한 돌출성', 'PP의 색채에 의한 돌출성', 'PP들 모양의 다양성'. 'PP들의 변화도', 'PP들 색채의 다양성', 'RPU의 돌출성', 'RPU의 다양성'이라는 7개의 상위 특징으로 수렴시킨 후, 이 7개의 상위특징들을 다시 'PP에 의한 다양성', 'RPU의 돌출성' 'RPU의 다양성'이라는 4개의 최상위 특징으로 수렵시키는 방식으로 위계화 하여 섬유 패턴 디자인 요소 분석체계를 구성하였다. 또한 대표적인 섬유 패턴 디자인에 대한 이 체계의 기술 가능성을 검토함으로써 본 체계를 수정·보완하였다.
