Spectroscopic ellipsometry 은 다양한 물질의 광학적 특징을 연구할 수 있는 강력한 기술이다. 현재 실리콘 웨이퍼 위의 박막 분석에는 그 효율성이 확실히 입증되어 있다. 그러나 현재 산업은 유리 기판위의 박막을 분석하기를 원하고 있다. Ellipsometry로 투명기판을 분석하기 위해서는 후면 반사에의한 비간섭성 효과를 고려해야 한다. 기존의 반사공식을 투명기판의 비간섭성을 고려하여 수정하였다. 투명기판 위의 샘플과 scratch를 낸 같은 샘플을 측정 분석하여 정확성을 확인하였다. 수정된 반사공식을 이용하면 디스플레이와 같은 투명재료를 이용하는 곳에 유용하게 사용될 것으로 기대되고 있다. A Spectroscpic ellipsometry is very strong technology to study optical properties of many materials. It has already substantiated a analytic efficiency about thin films above wafers to be made of silicon. However, the current industry needs thin films analyzed on a glass. When we analyze a glass using a ellipsometry, we have to consider a efficiency of incoherence due to reflect at the back side. So then, we slightly altered the original formula. We compared a scratched sample with a sample on the glass, because off getting a exactitude. Our technical development, using the changed formula, is expected the useful utilization in a part of using gIasses such as display.

The gamma irradiation effect of dried fernbraken was investigated on the physical and sensory qualities during and after soaking process. Dried fernbraken packaged in vacuum was irradiated up to 7 kGy with γ-ray produced by 132 Cs at 0℃. Moisture content and rehydration rate of gamma-irradiated fernbraken after soaking increased significantly depending on the irradiation doses(p<0.05). Lightness(L), redness(a) and yellowness(b) values of Hunter color system increased significantly in the gamma-irradiated fernbraken after soaking, compared with control, while the hardness and chewiness by the texture analyser decreased significantly in irradiated ones. Sensory evaluation results showed that the mean scores of flavor, appearance, taste, texture and over-all acceptability in soaked fernbraken irradiated were not significantly different from those in control, except higher preference score of texture in irradiated ones. From these results, it might be concluded that the irradiation does not affect the physical and sensory qualities of dried fembraken during and after soaking, especially in texture.

In this work, the characterization of adsorption of Cu, Zn and Cd on granular activated carbon in water has been studied. The factors that affect adsorption in boundary between activated carbon and wastewater are concentration, temperature, contact time, pH and so on. As the result of this study, the maximum adsorption amount of Cu occurred near pH 7, while that of Zn and Cd was near pH 9.6 and 10, respectively. As contact time and temperature are transformed, such factors as optimum contact time and temperature are taken into consideration in an adsorptive process of heavy metal because an adsorption and a reducing process occur. In isotherm of Freundlich, 1/n values of Cu, Cd capacity were between 0.16 and 0.5.

Followings are summaries of test results done on ten univeristy women majoring in Korean dancing at H and S universities with daucing experience of more than five years to evaluate anaerobic and aerobic power of Korean dancers using wingate test and gradually incresasing load method. 1. Korean dancer's anaerobic power parameters of peak power(W peak power), mean power(W mean power), and Fatigue Index were found to be 303.5+25.56 watt, 238.9+22.57 watt and 34.5+3.98% resoectuvety. 2. Korean daucer's aerobic power parameters of maximum oxygen absorption amount(VO_(2) max), anaerobic reverse level, lactase concentration accumulation in blood, and maximum heart pulse number were found to be 39.3+4.12㎖/㎏/min, 54.5+3.78%,8.3+1.79㎜ and 193.5+7.42beat /min. Above result shows that Korean dancer's auaerobic and aerobic power level is lower than that of other sports players and similar to that of common people and this resulted from long-term Korean dancing training concentrated on technies and action expression rather than on athletic power. However, as action performing in Korean dancing requires medium level athletic power to express work and static action expression also requires high concentration and athletic powers so training to intensify anaerobic and aerobic athletic ability is serionsly required for the consistent superior action performance and expression during the entire work performing duration.

To simulate accurate spectral reflectance from the red-green-blue output of a video digitizing system, a set of basis functions were computed. 1565 reflectance spectra of the chips in the Munsell Book of Color(Glossy) were measured with a spectrophotometer in KRISS. The autocorrelation matrix of these samples was formed and the eigenvectors and the eigenvalues of this matrix were computed by using Karhunen-Loeve transformation.

Study on the ignition of methane fuel system highly diluted with argon was carried out in the temperature range of 1515∼1905K behind a reflected shock wave to investigate the rate coefficients for the reaction CH3+O2=CH3O+O. Ignition delay times were measured by monitoring the light absorption by methyl radical at ca. 214nm and pressure profiles. Computer modeling study of methane oxidation was also performed using a GRI_MECH, version 2.11 mechanism for sensitivity analysis and calculation of ignition delay times. The correlation of τp with the maximum heat release rate (dq/dt)max in the reaction zone was also investigated.
