This research is to aim at presenting arrangement of colors, visual and symbolic through combined coupling ofI-Ging and Sackdong. This combined couplings is attempted to be approached by the following 4 conceptual steps :ⅰ) Is it appropriate to even try to coupleI-Ging with Sackdong\ulcorner ⅱ) Is the basic structure of Kwai an object of stripe colorizing\ulcorner ⅲ) What are the fundamental colors for this purpose\ulcorner ⅳ)combined of Kwai and the fundamental colors. Theoretical background for this study is as follows.ⅰ) Color accord and arrangements of existing Sackdong. ⅱ) An attempt to coupleI-Ging with Sackdong The purpose of this research is to expand concrete concept of Sackdong, which is to be utilized not only in costume design, but in the whole realm of design, by presenting feasible application of stripe coloredI-Ging. The summary of conclusion of this research is as follows. A. Is this aforementioned attempt academic\ulcorner B. Standardization of stripe-coloring is essential. Furthurmore we can conclued that the under-standing ofI-Ging and its basic philosophical background and the fundamental mechanism of colors in traditional costumes is necessary condition for standardization of Kwai. Along this path, however, conditions to be satisfied and priorities to be given depend upon the decision of an individual or a group. In my view, sripe-colorizing of 64 Kwais ofI-Ging followed by intuitive matching of colors with the in-terpretation of Kwais seems to be the most appropriate solution.

NGC147 and NGC185, paired satellites of the Andromeda galaxy, possess the same order of mass and analogous structures, but they show different star formation and different amounts of interstellar gas and dust. Therefore, we present the first reconstruction of the star formation history of NGC147 and NGC185. Asymptotic Giant Branch stars are highly evolved stars that are brightest in K-band. This maximum K-band magnitude is related to the birth mass of stars. As a result, we have found a 9.9 Gyr old single star formation epoch for NGC185 followed by relatively continuous star formation. NGC147, however, has passed through two star formation episodes; one is as old as ~6 Gyr and the other is as recent as ~850 Myr. Asymptotic Giant Branch stars are also important dust factories; by fitting Spectral Energy Distributions to observed near and mid infrared data for each star, we were able to measure the dust production rates of individual stars; on order of $10^{-5}M_{\odot}yr^{-1}$. Hence, we estimate the total mass entering the interstellar medium to be $1.06{\times}10^{-4}M_{\odot}yr^{-1}$ and $2.89{\times}10^{-4}M_{\odot}yr^{-1}$ for NGC147 and NGC185.

The object of this study was to obtain single oral dose toxicity of Arisaema Rhizome (Arisaema amurense f. serratum (Nakai) Kitag) aqueous extracts. Arisaema Rhizome (Chunnamsong in Korean) is one of the most important folk remedy plants used in Asia. In the study, a 28-day rat oral gavage study has been conducted with the extracts from Arisaema Rhizome at dose of 1,250, 2,500 and 5,000 ㎎/㎏/day. The following endpoints were evaluated: clinical observations, body weight, gross and microscopic pathology, clinical chemistry, and hematology. Based on the analysis of these endpoints, it was estimated that NOEL (no observed effect level) for male rats and NOAEL (no observed adverse effect level) for female rats are 5000 ㎎/㎏/day of the water-extracts from Arisaema Rhizome.

Pulse diagnosis is one of the representative diagnostic methods in Oriental medicine. In this study, a pulse pressure sensor array coated with silicone, which includes 6 piezo-resistive sensors and 1 thermistor, is fabricated for pulse measurement. It is necessary to coat the pulse sensor array with silicone to avoid the fracture or damage of pressure sensors when the sensor is in contact with the skin and a constant pressure is applied. However, the silicone coating on the pulse sensor array can cause signal interference among the sensors in the pulse sensor array. The interference number (IN), a calculation for expressing the degree of interference among channels, is changed according to the silicone thickness on the pulse sensor array. The IN is increased by a thick silicone coating, but the fabrication error, an important index for the mass production of the sensor array, is reduced by the thickness of the silicone coating. We propose that the thickness of the silicone on the pulse sensor array is an important consideration for the performance of the fabricated sensor and manufacturing repeatability.

본 연구는 확률교육 실제의 개선 방향을 제시하기 위해 2000년 이후 출간된 국내 확률교육 연구논문 85편을 분석하였다. 연구 결과, 지난 20년 동안 국내 확률교육에 관한 논문의 양이 상당히 적은 것으로 나타났으며, 인간 대상 연구가 인간 비대상 연구 비중보다는 조금 더 높았으나 더 많은 교수실험 연구가 필요함을 확인하였다. 연구 주제별 분석 결과, 독립성과 조건부확률, 조합과 세기가 많이 다루어지고 있었는데 국외에서는 이 주제들이 어린 아동들을 대상으로 다루어져야 하고 직관적인 수준에서 어떻게 교수-학습이 가능할지 많이 연구되고 있는 것에 비해, 국내에서는 대부분 고등학생 이상을 대상으로 이루어졌음을 확인하였다. 이러한 결과를 바탕으로 향후 국내 확률교육 연구의 과제와 발전 방향에 대한 시사점을 도출하였다.

Nondestructive nonlinear acoustic method in two dimensions is suggested as a useful tool for detecting defects in a composite layer-structured material. Spectrum level changes in fundamental and harmonic frequencies are observed in the presence of a layer type defect compared with in the absence of such a defect. It is proposed in this study that such spectrum changes we due to the mode conversion. The layer type defect makes different normal modes due to different boundary conditions in the thickness direction for the Lamb waves propagating in a layer-structured material. Specifically, the normal mode with the fundamental frequency in the case of the water-layer gap is converted to the normal mode with the second harmonic frequency in the case of the air-layer gap.
