To investigate antioxidative and antiaging effects of yellow and black soybeans in vivo system, male SD rats (n＝24) were fed the diets containing casein (C), yellow soybean (YS) or black soybean (BS) for 8 weeks. Experimental groups showed the preventive effect on lipid and protein oxidation, especially protein oxidation of plasma was significantly inhibited in BS group. SOD and catalase activities were not different among the groups, but hepatic glutathione peroxidase (GSH-px) activity was significantly lowered in YS and BS groups compared with control group. The contents of superoxide anion radical in cytosol were significantly lowered in experimental groups compared with control group. And hydroxyl radical was slightly lowered in soybean groups. Lipofuscin accumulation on the heart and eyes of rats was effectively inhibited by yellow soybean and black soybean, respectively. In conclusion, these results suggest that yellow soybean and black soybean have the antioxidative/antiaging effect in vivo system and they have similar activities despite different color of seed coat.

In 7 kinds of Gulbi purchansed from Yosu, Sunchon and Chinju, N-nitrosamine (NA) such as N-nitrosodimethylamine (NDMA), N-nitrosodiethylamine (NDEA) and N-nitrosodipropylamine(NDPA), were detected and their content was 2.8∼78.3$\mu\textrm{g}$/kg, trace and 0∼1.4$\mu\textrm{g}$/kg, respectively. This experiment was conducted to study the effect of processing conditions on NA formation in the salted and dried yellow corvenia(Guibi), prepared by using the different salting method like dry and brine salting by pure and crude salt. NDMA, NDEA and NDPA were not detected in raw sample, but NDMA content increased in yellow corvenia during its salting (27.6∼37.4$\mu\textrm{g}$/kg), and then drastically decreased in Gulbi stored for 40 days, ranging from 2.8 to 4.3$\mu\textrm{g}$/kg. Content of above NA was inhibited more effectively in the samples prepare with brine salting method than with the dry salting method during its processing and storage. Especially, NA in the sample prepared with brine salted and dried yellow corvenia using the pure salt was detected in the lower concentrations, and that of NDMA, NDEA and NDPA was 2.8∼27.6, trance and ND-2.7$\mu\textrm{g}$/kg, respectively.

We conducted the experiment in order to evaluate the control effect of whitefly using the sticky trap. Both Bemisia tabaci and Trialeurodes vaporariorum were more attracted to yellow sticky trap than white or blue colored traps. When yellow sticky traps were installed in different height around tomato, catches of B. tabaci were not significantly different among the traps and catches of T. vaporariorum on the traps in the upper position were more than lower position. T. vaporariorum was more attracted to trap when host plant is smaller. The attracted number to yellow sticky traps were not significantly different between whiteflies (B. tabaci and T. vaporariorum) and their parasitoids (Encarsia formosa and Eretmocerus mundus). Yellow sticky trap reduced population density of both B. tabaci and T. vaporariorum by more than 80% on tomato nursery in a screen cage. Population density of whiteflies in greenhouse installed yellow sticky traps was less than one third of that in untreated greenhouse.

The effect on the particulate matters in the atmosphere was investigated in Seoul area from March, 1984 to Aprill, 1985. Aerosols were collected by filters on nine stages Andrsen Air Sampler, and size distribution and total concentration of the aerosols, Fe and Pb were measured. In spring with Yellow Sand the concentration of particles in aerosols was 185.55$\mug/m^3$ and CP/TA was 65.9%. But in spring without Yellow Sand those of particles was 135.45$\mug/m^3$ and CP/TA was 58.6%. Accordingly the concentration of coarse particles with Yellow Sand was higher than without them in Spring. Above results indicate that in Seoul Area the main source of air pollution originated from natural burdens, especially from soil. The concentration of Pb was similarly valued through both seasons in Seoul area but fine particles valued above coarse particles. On the other hand, in urban area, the natural and anthropogenic sources have influenced on the concentration of Pb. With referred to particle size distribution for Fe, the concentration of coarse particles was 0.168$\etag/m^3$ (CP/TA: 74.3%) in Spring with Yellow Sand, 0.096$\mug/m^3$ (CP/TA: 71.6%) without Yellow Sand and 0.083$\mug/m^3$ (CP/TA: 67.4%) in winter, respectively. Compared with fine particles, all of them were higher. It indicated that the origin of coarse particles in urban air was not related to anthropogenic source. The concentration of Fe was influenced by Yellow Sand and contributed to air pollution.

The effect of atmospheric gas on the surface cleanliness in the batch annealing furnace(BAF) is presented. It is very important to improve the surface cleanliness to investigate the surface defects such as carbon contamination, smudge and yellow color phenomenon on the surface of steel sheet. In order to study the occurrence of surface defects of steel sheet, the annealing operations were carried out in the H2 BAF with 75% hydrogen and conventional BAF with 4% hydrogen. The hydrogen is important factor that affect the energy saving in the entire annealing cycle and the surface cleanliness. In the conventional BAF, it shows that to protect the yellow color phenomenon the proper finish temperature is $80^{\circ}C$ and in the smudge sample the oxidized thickness has the depth of $120{\AA}$.

An experiment was carried out to study the effect of environmental color on the eating behaviour in broiler chicks. A total of ninety broilers with average 350g of initial body weight were randomly assigned in the $3{\times}3$ randomized complete block design with 3 treatments(yellow, blue, red) and 10 birds per replication of various environmental color at walls, feeders and electric bulbs. The results obtained from these experiments are summarised as follows: 1. Feed Intake and average daily gain were significantly(P<0.05) increased by yellow colored environment. 2. Eating time and eating rate were significantly higher in the red colored than the other, indicating that yellow colored environment would maximize body weight gain and feed conversion for broiler chicks.

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.
