The purpose of this study was to investigate the properties of yellow layer cake made with bamboo leaf powder. Physical properties of the medium and cake flour with bamboo leaf powder were tested by falling number, farinogram, alveogram and after making yellow layer cake, which were tested by rheometer and water activity etc. We found that falling numbers increased with addition of bamboo leaf powder and adding bamboo leaf powder to the flour decreased peak viscosity, holding strength, final viscosity etc. The p value of the alveogram increased for the flour containing bamboo leaf powder increased, but development time and stability decreased. The water activity of the yellow layer cakes made with bamboo leaf powder decreased during storage, but they did not show significant differences. The results of the sensory test showed that the 3% of addition of bamboo leaf powder had the best scores.

Yellow sand event has been studied using SeaWiFS data in order to examine the aerosol optical characteristics in the Yellow Sea and their influences on the atmospheric correction for the ocean color remote sensing. Two SeaWiFS images of April 18 and April 25, 1998, representing Yellow Sand event and clear-sky case respectively, are selected for emphasizing the impact of high aerosol concentration on the ocean color remote sensing. It was shown that NASA's standard atmospheric correction algorithm treats yellow sand area as either too high radiance or cloud area, in which ocean color information is not generated. SeaWiFS aerosol optical thickness is compared with nearby ground-based sun photometer measurements and also is compared with radiative transfer simulation in conjunction with yellow sand model, examining the performance of NASA's atmospheric correction algorithm in case of the heavy dust event.

It was many differances to evaluate of the effect of excipients on colour fading in FD & C Yellow No.5 by use Tintometer and nearly is not effective in FD & C Red No. 2. When we observed colour fading in suger coating formulations by tintometer, FD & C Red No.2 was appeared to follow zero order reaction and FD & C Yellow No. 5 was not follow zero order reaction or first order reaction. Also, we could know the tendency of colour fading by visible spectrum, but it was net suitable method for this experiment more than by tintometer. The relative colour fading effect of the surfactants(Polysorbate) was as follows: Tween 60> Tween 80> Tween 20. In addition to, Benzalkonium chloride was reacted with FD & C Yellow No.5, so the stronger colour was appeared. On the other hand, the weaker colour was appeared in FD & C Red No.2. While, the sunscreening agents was not almost effective in colour fading of FD & Yellow No. 5 and FD & C Red No. 2.

The Yellow-Sand phenomena occurred during the period from l0C to 14C in Korea have been investigated using the historical record of the Koryosa. It is written as the "dust rain"or "mud" which means the falling down of dust from the sky. The authors have extracted 50 historical writings of dust rain from the Koryosa. The results show that the observation records concerning Yellow-Sand phenomenon for the period of Korea Dynasty (918~1392) are described with the scientific accuracy for the Yellow-Sand phenomena as the pure dust phenomena, the mixture of Yellow Sand with snow or rain, and the Yellow-Sand associated with fog or hail, etc. It is also found that the occurrence of Yellow-Sand phenomena was the incomprehensible natural phenomena such as Yellow-Sand were interpreted as a warning from the Heaven to the king and people of their fail in moral principles.in moral principles.

Yellow gold는 아름다운 광택과 손쉬운 가공성의 장점 때문에 장신구를 비롯한 다양한 분야에서 그 활용 가치가 매우 높다. 본 연구에서는 yellow gold의 hardness 강화 및 품질향상을 위하여 다양한 열처리 조건 별 기계적 특성 변화를 비교 관찰 하였다. 열처리 전 yellow gold alloy의 구성성분을 조사하기 위하여 EPMA와 ICP-MS를 사용하여 정성분석 및 정량분석 결과를 수치화 하였다. 총 44개의 14K yellow gold를 사용하여 $750^{\circ}C$, 30 min 의 조건에서 solid solution treatment 후 $200{\sim}350^{\circ}C$ 온도 범위에서 $50^{\circ}C$ 간격으로 age-hardening을 실시하였다. 또한 열처리 전과 후 grain 들의 배열 및 size 변화를 관찰하기 위해 식각을 실시하였다. 식각된 시료는 optical microscope (OM)을 통해 각 열처리 조건에 따라 전 후 변화를 관찰 하였다. 열처리 전 14K yellow gold의 hardness의 평균값은 120.6 Hv를 나타내었다. Solid solution treatment 후 hardness는 95.7 Hv로 평균값이 감소하였고, age-hardening 후에는 14K yellow gold는 $260^{\circ}C$에서 159.8 Hv, $270^{\circ}C$에서 170.2 Hv로 열처리 전에 비해 약 41% 증가된 결과를 나타내었다. 하지만 $270^{\circ}C$ 부터는 over-aging 현상을 나타내었다. OM 분석 결과 열처리 전 불균일했던 grain들의 배열이 solid solution treatment 및 quenching 후 다소 균일해 짐을 확인할 수 있었고, grain size 또한 열처리 전에 비해 증가함을 알 수 있었다. Solid solution treatment 후 모든 시료의 hardness 값이 전반적으로 감소하였다가 age-hardening을 통해 grain들의 배열이 점차 안정화 되면서 hardness가 증가 하였고, over-aging 구간에서는 급격히 감소하는 경향을 나타내었다. 이 결과로 우리는 14K yellow gold에 대한 age-hardening 최적조건을 도출 하였고, 각 열처리 조건 별 grain 배열 상태의 변화를 관찰 할 수 있었다.

It is, as everyone knows, very important for human beings to protect and conserve marine environment. We has believed the ocean is so wide and deep that it cannot be polluted. But it has begun to doubt the capacity of self-purification of the ocean due to pollution arising from marine casualities. It has proved that semi-enclosed sea is likely to be polluted and cannot be restored easily once pollution occurs. Therefore, first of all it is important to take preventive measures for prevention of marine pollution in the semi-enclosed sea like the Yellow Sea. Many of regional conventions for prevention of marine pollution have come into existence. this dissertation was set out for the fact that the Yellow Sea is semi-enclosed sea which is vulnerable to marine pollution. It is desirable not to deal with marine preservation of the Yellow Sea by a single exclusively but to deal with it by cooperation of all coastal states under the present circumstances. I proposed a program of regional cooperation to protect and conserve the Yellow Sea. This program must be progressed with gradual arrangements. First, they must establist a basic cooperation committee to work basic affairs on the protection of marine environment within the Yellow Sea. The Committee Mainly play parts of study and research concerned with pollution of the Yellow Sea in the non-governmental side and consist of legal and scientific experts. Second, they must establish the control Committee to prevent marine pollution of the Yellow Sea substantially. There is a reason that regional cooperation cannot be directly concluded with the regional tready. Because there is a problem of Recognition of States left. In principle, a subject of tready must be a state in the International Law. But they have not made Recognition of State which is demanded by International Law between North and South Koreas. Therefore, the Control committee must play a substantial part of prevention from pollution instead of the treaty. Finally, we concluded tentatively named $\ulcorner$Convention on Regional Cooperation for Protection of Marine Environment of the Yellow Sea from Pollution$\lrcorner$ if the matter is settled which is related to Recognition of States in the International Law.

A total of 116 surface sediment samples were obtained on the Yellow Sea and analyzed for grain size and geochemical elements in order to interpret the present sediment transportation. Thirty-nine cores and 3,070 line-km shallow seismic profiles are analyzed for sedimentary records of Yellow Sea in the past. Results show that the boundary of sediment transport between Korean side and Chinese side is about between $123^{\circ}E$ and $124^{\circ}E$. The similar result is produced from Shi et al. (in this publication). Two cyclonic patterns of surface sediments are recognized in the northeastern and southwestern Yellow Sea, while the strong front zone of the mud patch and sandy sediments are found in the southeastern Yellow Sea (the southwestern part of Korean coasts). The formation of fine-particle sediment packages, called for Northwest Mudbelt Deposit (NWMD), Hucksan Mudbelt Deposit (HSMD) and Jeju Mudbelt Deposit (JJMD), are resulted from eddies (gyres) of water circulations in the Yellow Sea. NWMD has been formed by cyclonic (anticlockwise) eddy. NWMD is composed of thick, homogeneous, relatively semi-consolidated gray clay-dominated deposit. On the other hand, HSMD and JJMD are formed by anticyclonic (clockwise) eddies. They are thick, homogeneous, organic-rich gray, silt-dominated deposit. Both core and surface sediments show that the middle zone across Chinese and Korean side contains bimodal frequency of grain-size distribution, indicating that two different transport mechanisms exist. These mud packages are surrounded by sand deposits from both Korea and China seas, indicating that Yellow Sea, which is the shallow sea and epicontinental shelf, is formed mostly by sand deposits including relict sands. The seismic profiles show such as small erosional/non-depositional channels, sand-ridges and sand-waves, Pleistocene-channelfilled deposits, a series of channels in the N-S major channel system, and thick Holocene sediment package, indicating that more complex sedimentary history exists in the Yellow Sea.

In serious crimes, bloody fingerprints are crucial evidence that make links between suspects and victims. There have been many studies related to bloody fingerprints for a long time. There are many comparative studies for effectiveness of Acid Fuchsin and Acid Yellow 7, but nothing about Eosin-Y in this country. Acid Fuchsin is a useful reagent that has unique red color distinguishing from light colored background. but it is useless on dark surfaces. In order to make it visible, we should use BVDA Gel lifters. On the contrary this, Acid Yellow 7 makes stronger fluorescence on a dark background. In this study, we got the conclusion that Eosin-Y is more useful than the others not only on dark background but also light background.

The purpose of this study were to investigate characteristic changes on nonwoven fabric for disposable work clothes by the yellow soil printing. It separate grind yellow soil as two different size of particles $45\sim52{\mu}m$ and $53\sim65{\mu}m$ for hand screen printing on three kind of nonwoven fabrics. To examine the effect of yellow soil printing on nonwoven fabric were to observe, dyeability by using spectrophotometer, moisture regain by oven method, air permeability, anion property and antibacterial activity. The results were as follows: When yellow soil concentration increased from 5 to 10%, K/S value also increased from 1.05 to 1.88. When yellow soil concentration increased, moisture regain also increased. In same concentration, moisture regain occurred higher as particle of small size. Air permeability decreased when the charcoal printing concentration increased. Anion occurrence appeared $140\sim160ion/cc$ from three different kinds of nonwoven fabrics in 3% and 9% yellow soil concentration. Therefore, occurred anion ineffectively. In concentration of 3%, rate of deodorization measured as 89%, 83% and 87%, and 9% concentration caused 96%, 86% and 93% of high deodorization. Antibacterial activity examination in nonfinished nonwoven fabric resulted range of 60%, however, 3% and 9% concentration finished nonwoven fabric resulted 99.9% of excellent antibacterial activity Surface temperature increased $1.5\sim2^{\circ}C$ by yellow soil finishing.
