  • Modeling and simulation has widely been used in the weapon systems acquisition, the military training, and the warfighting experimentation. A study of the warfighting experimentation had been relatively scarce in comparison to other fields (acquisition, training). The main reasons are 1) reliability of simulation model isn't sufficient and 2) collaboration between professional groups is too difficult. To solve this problem, the application framework of warfighting experimentation for military operations was proposed. And through the framework, the case study about sea fight was fulfilled. This framework provides connectivity between warfighting experimentation and military operations planning procedure. With improved reliability, active application of warfighting experimentation could contribute to fighting capability.

  • The warfighting experimentation is the most important for the weapon acquisition process because the warfighting experimentation shall support the operation effectiveness as well as acquisition logicality. Therefore, ROK Navy is starting to set up the next generation warfighting experimentation systems. According to literature studies, there have been many studies regarding the interoperability of Simulators(Virtual) and Exercising models(Constructive), but not for studies regarding interoperability between Simulators(Virtual) and Analysis models(Constructive) that is the core component of next generation maritime warfighting experimentation systems. This study is dealing with the V-C(Analysis model) interoperability test and methodology of interoperation analysis. The purpose of the study is to provide the new analysis methodology through V-C(Analysis model) interoperation, which can be applied for the concept of operations(CONOPS) of next generation maritime warfighting experimentation systems. In addition to that, the study validates the suggested analysis methodology by the case study of a naval operation.

  • This study was intended to suggest the desirable direction in the 7th national curriculum revision through the illustration analysis of the elementary science textbooks in the 6th national curriculum. The analysis system was composed of two categories, (1)the kind of illustrations (2)the .ole of illustrations The kind of illustrations was divided into five subcategories such as photograph, pictures, illustrations, cartoons and diagrams. And the role of illustrations was divided into four subcategories such as motive induction, guidance for experimentation, the presentation of data and the results of experimentation. Each sentence in the textbooks was considered as an analyzing units. The frequency and percentage of each category were counted and the rates were calculated. The findings could be summarized as follows: 1. The illustration in the primary science textbooks was mostly composed of photographs (87.1%). 2. The examination of the role of illustrations showed that the presentation of data was 46.2%, the guidance for experimentation 38.4%, the results of experimentation 8.6% and the motive induction 6.8% respectively. 3. In the domains of physical and chemical science, the role of guidance for experimentation was emphasized. But the biological and earth science domains showed high tendency of the presentation of data.

  • Response surface methodology (RSM) is a useful collection of experimentation techniques for developing, improving, and optimizing products and processes. When we are to estimate second-order regression model and optimize quality characteristic by RSM, central composite designs and Box-Behnken designs are widely in use. However, in developing cutting-edge products, it is very crucial to reduce the time of experimentation as much as possible. In this paper small-sized second-order designs are introduced and their estimation abilities are compared in terms of D-optimality, A-optimality, and variance of regression coefficients, ease of experimentation, number of experiments. Then we present a guideline of using specific designs for specific experimentation circumstances. The result of this study will be beneficial to experimenters who face experiments which are expensive, difficult, or time-consuming.

  • The most bottleneck of development of automation excavator system is the making mathematical linear model. Because of non-linear of control circuit, cylinder, join in hydraulic circuit, and heavy loading so on. Therefore, whatever robust controller is designed, real experimentation is necessary. But, a real experimentation has many risks. The excavator is expensive and large size. Therefore a development of experimentation system is difficult and not safe. Specially, there have a difficulty, because of big noise. So, on experimentation is difficult in school. Manufacturing pneumatic excavator modeland using system identification, design a system transfer function in this paper. Also, planning m-PID Controller using CDM, and examining usefulness applied to actuality model.

  • The purpose of this study was to research the experimental dance drama of the world-class choreographer Pina Bausch who, in the latter half of the twentieth century, broke the boundaries of genres with radical experimentation and overcame the limits of expressionism dance tradition, creating her exclusive dance drama. Pina Bausch was born in Germany and naturally inherited the expressionist dance tradition, but did not stay there and introduced the post-Brecht drama theater through radical experimentation. Her bold attempts have overcome the limitations of the expressionist tradition and have revolutionized the genre of dance and have played a role in expanding dance arts while pioneering her own dance language.

  • 본 연구에서는 이언 해킹(Ian Hacking)의 실험 철학에 대한 철학적 관점을 탐구하고 이 관점이 학교 실험 교육에 미칠 영향에 대한 논의하였다. 그간 다수의 철학자들은 실험이 이론을 검증할 때에만 중요하다는 이론 선행적인 관점을 주장하였다. 이와 마찬가지로 학교 교육에서도 실험의 주요 목적은 이론의 확인과 입증에 초점을 맞춘 관점이 주류를 이룬 것으로 보인다. 그러나 이러한 이론 선행적인 관점과는 대조적으로 해킹을 포함한 실험 철학자들은 실험 자체가 자율성과 생명력을 갖는다는 주장을 제안하였다. 해킹은 개입하기와 조작하기를 통해 실험의 이론 자율적인 성격을 강조하면서 실험에서 그동안 상대적으로 간과되었던 도구 사용, 재료, 과학자의 솜씨와 같은 요소들의 중요성을 강조하였고, 과학 활동에서의 실험의 역할과 그의 중요성을 재고하였다. 본 연구에서는 이러한 철학적 입장이 학교 실험교육에도 적용할 수 있는 것으로 보았으며, 본 연구에서 제시하는 현상중심의 관점을 통해 도구 사용, 실험자의 개입, 모델링 활동과 같은 과학적 실천을 가르치는 데 도움이 될 것으로 예상한다.

  • Purpose: In this paper we propose modified Notz designs which are useful to experimenters who want to adopt the sequential experimentation strategy and to estimate second-order regression model with as few experimental points as possible. Methods: We first present the design matrices and design points in two or three dimensional spaces for such small sized second-order designs as small composite, hybrid, and Notz designs. Modified Notz designs are proposed and compared with some response surface designs in terms of the total number of experimental points, the estimation capability criteria such as D- and A-optimality. Results: When sequential experimentation is necessary, the modified Notz designs are recommendable. Conclusion: The result of this paper will be beneficial to experimenters who need to do experiments more efficiently, especially for those who want to reduce the time of experimentation as much as possible to develop cutting-edge products.

  • The purpose of this study is to find out the effects of taping therapy on muscle activities between the group of taping therapy treatment and control group before or after exercises. The subjects are 18 S college's healthy male students who do not have any problems in the legs and could bend the knee joint normally. Considering physique, condition of health and capacity for locomotion, 3 groups of each 6 persons for the experimentation were classified. Three groups composed of control group without taping therapy treatment for control group, group I with taping therapy treatment only before the experimentation and group II with taping therapy treatment during 24 hour. before and after the experimentation. EMG MP150 was used to evaluate the parameter of the lower leg's muscle activities the exercise before 5 min. after 10 min. and after 24 hour. for the experimentation. Compared with control group, group I and group II had more increased muscle activities in vastus lateralis and rectus femoris and was statistically significant. And group I and group II also had more increase in muscle activities than control group in vastus medialis, although there was no statistically significant. We found that taping therapy increased muscle activity positively. The application of taping therapy could be used not only for preventive effects for sports man but also therapeutic effects for general people.
