  • In this study, Particulate carbon were determined from 1990 to 1995. The annual variation were investigated. The sampling was carried out using high volume air sampler. Average concentrations of EC and OC during the yellow sand event were $25.70{\mu}g/m^3$ and $13.91{\mu}g/m^3$, respectively, $22.10{\mu}g/m^3$ and $10.33{\mu}g/m^3$ during the non-yellow sand event. TC concentration of TSP were 10.7% during the yellow sand event and 20.6% during the non-yellow sand event. Average concentration rate of EC and OC of TC were 64.9% and 35.1%, respectively during the yellow sand event, 67.6% and 32.4% during the non-yellow sand event.

  • Among 96 color combination stimuli, male students evaluated 47 set as harmonized, but female students evaluated 32 set, so proved that male's range of harmony more extensive than that of female. Specially red shirt and yellow red necktie in all tone was evaluated as harmonized coloration by both male and female students. Female evaluated as the best harmonious coloration that red shirt-yellow necktie in dark, blue shirt-yellow necktie in dark, purple shirt-red necktie in light, green shirt-blue necktie in dull, and male evaluated red shirt-yellow red necktie in light, blue shirt-yellow necktie in light, purple shirt-red necktie in light, green shirt-yellow necktie in dark. It is significant difference between female and male on red-green in vivid, and blue-purple in vivid, blue-blue in dull, blue-yellow in dark, and purple-purple in dull. And shirt color and necktie color, necktie color and tone, tone and perceiver' gender influenced on the harmony evaluation by interaction.

  • 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.

  • In this technical information, the springtime TSP measurement data between 1993 and 1996 at Kosan are presented. Based on the data, it was found that the concentrations of crustal species increase when Yellow Dust phenomenon occurs. Among anthropogenic species, the concentration of Pb and NO$_3$$^{[-10]}$ increase when Yellow Dust phenomenon occurs. Further research agenda are discussed to study the effects of Yellow Dust.

  • 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.

  • 황사가 식물플랑크톤에 미치는 영향을 파악하기 위해, 황사가 발생한 2006년 4월 22 ~ 26일까지 태안반도 인근해역에서 현장조사 및 생리실험을 수행하였다. 황사발생동안 식물플랑크톤 군집은 $26{\sim}290{\times}10^3cells{\cdot}L^{-1}$의 범위로 다소 낮은 현존량과 주요 분류군인 돌말류의 증가, 특히 혼합해역의 대표종인 Paralia sulcata와 같은 저서성 돌말류의 증가가 뚜렷하였다. 또한 황사발생 후의 Chl-a 농도는 황사 발생 전의 조석에 따른 Chl-a 농도변화범위를 초과하였다. 황사투여실험에서는 황사투여 농도가 증가함에 따라 일차생산력은 점차 감소하였고, 최대 탄소 동화계수 역시 같은 경향을 보였다. 48시간 배양실험에서는 황사투여 초기(T0)에 실험구(test)가 대조구(control)에 비해 낮은 일차생산력을 보였으나, 48시간 후(T48)에는 실험구가 대조구보다 높은 일차생산력을 보였다. 특히 실험구는 초기보다 48시간 후의 일차생산력이 약 321 %로 크게 증가하였다. 따라서 중국과 인접한 조사해역의 식물플랑크톤은 황사와 함께 수반되는 강한 물리적 환경이 발생초기에 식물플랑크톤의 성장을 일시적으로 저해시킬 수 있으나, 이후 안정적인 수괴가 지속될 경우 식물플랑크톤의 성장을 촉진시키는 잠재적인 요인으로도 파악되었다.

  • 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.
