To quantitatively estimate mass contribution of long-range transported yellow sand, their sources should be separated independently from various local soil sources having similar elemental compositions. While it is difficult to estimate total mass loadings of pure yellow sand by traditional bulk analysis, it can be clearly solved by an particle-by-particle analysis. To perform this study, two yellow sand samples and three local soil samples were collected by a mini-volume sampler. These samples were three analyzed using a scanning electron microscope(SEM) equipped with an energy dispersive x-ray analyser (EDX) was used to obtain basic chemical information of individual yellow san particles. A total of 19 elements in a single particle were measured to develop a source profile with newly created homogeneous particle classes (HPCs) as chemical variables. The present study showed that the yellow sand samples as well as three local soil samples were characterized with reasonably well created HPCs. Finally the mass fraction of each HPC in each sample was calculated and then compared each other.

We have investigated the optical and electrical properties of surface mounted white light emitting diode (LED) chips prepared by using yellow phosphors on the blue LED chip. The yellow phosphor mixed with transparent epoxy was coated on the prepared LED chip. The optimum mixing conditions with epoxy and yellow phosphor is obtained at the mixing ratio of epoxy:yellow phosphor = 97:3 wt%. The maximum luminance and light emitting efficiency are above $80,000cd/m^2$ and 23.2 lm/W, respectively, at the bias voltage of 2.9 V. There was no distinct change in the luminance strength with changing of the yellow phosphor ratios. The current of the white LED chip is about 30 mA at 2.9 V.

The objective of this study was to investigate the correlation between cattle breeds and deposit of adipose tissues in different positions and the gene expressions of peroxisome proliferator-activated receptor gamma ($PPAR{\gamma}$), fatty acid synthase (FASN), and Acyl-CoA dehydrogenase (ACADM), which are associated with lipid metabolism and are valuable for understanding the physiology in fat depot and meat quality. Yanbian yellow cattle and Yan yellow cattle reared under the same conditions display different fat proportions in the carcass. To understand this difference, the expression of $PPAR{\gamma}$, FASN, and ACADM in different adipose tissues and longissimus dorsi muscle (LD) in these two breeds were analyzed using the Real-time quantitative polymerase chain reaction method (qRT-PCR). The result showed that $PPAR{\gamma}$ gene expression was significantly higher in adipose tissue than in LD in both breeds. $PPAR{\gamma}$ expression was also higher in abdominal fat, in perirenal fat than in the subcutaneous fat (p<0.05) in Yanbian yellow cattle, and was significantly higher in subcutaneous fat in Yan yellow cattle than that in Yanbian yellow cattle. On the other hand, FASN mRNA expression levels in subcutaneous fat and abdominal fat in Yan yellow cattle were significantly higher than that in Yanbian yellow cattle. Interestingly, ACADM gene shows greater fold changes in LD than in adipose tissues in Yan yellow cattle. Furthermore, the expressions of these three genes in lung, colon, kidney, liver and heart of Yanbian yellow cattle and Yan yellow cattle were also investigated. The results showed that the highest expression levels of $PPAR{\gamma}$ and FASN genes were detected in the lung in both breeds. The expression of ACADM gene in kidney and liver were higher than that in other organs in Yanbian yellow cattle, the comparison was not statistically significant in Yan yellow cattle.

Phalaenopsis (Phal.) "Yellow Dream" was developed by the National Institute of Horticultural & Herbal Science (NIHHS), Rural Development Administration (RDA) in 2005. This hybrid came from the progenies of a cross between Phal. "3031" which has yellow colored petals and small plant size, and Phal. "Golden Emperor" which has yellow colored petals with red spots and small plant size in 1995. "Yellow Dream" was finally selected in 2005 after the investigation of the growth and flower characteristics from 2000 to 2004. "Yellow Dream" had a yellow (Y4D) base color and light orange stripe petals (ORN34A) with a red lip (R42D). The average leaf length and flower width of "Yellow Dream" were 21cm and 6.8cm, respectively. It has a half erect leaf form and is a fast growing cultivar. This hybrid is relatively easy to make clones.

To investigate the effect of yellow dust on phytoplankton, a field survey and physiological experiments were carried out in the waters near Taean Peninsula from April 22 to 26, 2006, when yellow dust occurred. Phytoplankton populations during the yellow dust period were in the range of $26{\sim}290{\times}10^3cells{\cdot}L^{-1}$, a somewhat low standing crop. An increase in diatoms (a main taxonomic group), especially benthic diatoms such as Paralia sulcate, a typical species for active mixed sea water areas, was also remarkable. In addition, the Chl-a concentration after yellow dust exceeded the Chl-a concentration change range according to the tide before yellow dust. As the concentration of yellow sand increased in a yellow sand treatment experiment, primary productivity decreased, and the maximum assimilation number showed the same tendency. In the 48h culture experiment, primary productivity of the test group was lower than that of the control group at the early stage (T0) of yellow sand treatment, but after 48 hours (T48), the test group showed higher primary productivity than the control group. In particular, the primary productivity of the test group significantly increased to 321 % after 48 hours. Therefore, strong physical environment accompanied by yellow dust may temporarily inhibit the growth of phytoplankton in the waters adjacent to China in the early stage of yellow dust, but the formation of stable water mass has also been identified as a potential factor promoting the growth of phytoplankton.

This study carried out to investigate the effects of yacon powder on yellow layer cake made with weak flour. After making yellow layer cake with yacon powder, water activity, crumb texture, crumb color, and sensory characteristics were investigated. After 1 day of storage, Aw value of control cake with weak flour did not show any significant differences, whereas those with 2, 4, and 6% yacon powder showed a significant increase in Aw. During storage, the Aw values of yellow layer cakes containing yacon powder decreased. Hardness and gumminess of yellow layer cakes containing yacon powder decreased compared to those of control, whereas springiness and cohesiveness of yellow layer cakes increased compared to those of control. Hardness, springiness, cohesiveness, and gumminess all increased with storage time. Further a higher percentage of yacon powder was associated with lower L and b values as well as a higher a value. The micrographs of yellow layer cakes with yacon powder showed slightly coarser porosity than that of control. The results of the sensory test showed that the overall acceptability of 2% yacon powder cake was the highest.

This study examined the quality characteristics of soybean curd prepared with the addition of yellow paprika juice. The yield rate, pH, and ${\Delta}E$, L, a, and b values of the yellow paprika juice were 80.56$\pm$0.07%, 5.41$\pm$0.06, 25.34$\pm$0.14, 24.83$\pm$0.13, -0.61$\pm$0.24, and 26.28$\pm$0.27, respectively, and its moisture, crude ash, carbohydrate, crude protein, crude lipid, vitamin A, and vitamin C contents were 93.08 g, 0.40 g, 4.95 g, 0.85 g, 0.02 g, 25.26 IU, and 115.08 mg, respectively. The yield rate of the soybean curd did not differ significantly according to the level of added yellow paprika juice, however, there was a significant decrease in pH and a significant increase in acidity. The ${\Delta}E$ and b values of the soybean curd increased as the amount of yellow paprika juice in the formulation increased, whereas the L and a values decreased. Furthermore, hardness significantly increased as the level of yellow paprika juice increased. In terms of overall acceptability, the preferred soybean curd samples were the control and that containing 10% yellow paprika juice.
