Advances in white OLED tandem architecture are discussed.With these structures, stable and low-power full color AMOLED displays can be fabricated that are anticipated to be suitable for large area applications such as TVs. With a tandem architecture, efficient (24 cd/A) OLED structures with exceptional stability (${\sim}100,000\;h$ at $1000\;cd/m^2$) are described. In addition, excellent color gamut (>100% NTSC) can be attained by incorporating advanced color filters into the AMOLED backplane in a typical bottom-emitting configuration.

The PLA2G4A catalyzes the hydrolysis of membrane phospholipids to release arachidonic acid, which is metabolized into lipid-based cellular hormones that regulate inflammatory response. The circulating blood cell numbers can be influenced by stress, infection or inflammation. Quantitative blood cell count traits analysis for the 19 SNPs in the PLA2G4A gene in the Korean Association Resource (KARE) cohort (7551 subjects) was performed. The only one SNP (rs10752979) in the all blood cell count was satisfied with the Bonferroni corrected P-value (<0.00263). Furthermore, 6 of the 19 SNPs in the PLA2G4A gene showed a weak or moderate association with blood cell count (P-values: 0.0048~0.042), suggesting the clue of an association between the PLA2G4A gene and blood cell count, especially white blood cell count. This study may provide insight into the genetic basis of blood cell count related with reaction of infection.

Haploid cell obta-ined from microspores of Solanum nigrum were cultured on two kinds of medium, "Callus-inducing medium" and "Differentiation medium", in order to conduct histological studies of callus and examine differentiation of plantlets. On the callus-inducing medium the calli grew rapidly. The bulk of callus mass was light brown colored "Wet callus" covered on the surface with thin layers of rough and gleaming "White callus". The wet callus was consisted of parenchyma and meristematic tissues, while the white callus had no meristematic tissues. Large parenchyma cells, by successive divisions, became multicellular or poly nucleate cells which developed later to be meristematic tissues. The calli embedded on the differentiation medium quickly turned to dark brown color. Plantlets, however, came out later from these blackened callus mass. In the callus sectioned about ten weeks after imbedding on the differentiation medium, radially elongated tissue, concentric tissue, epidermis, tracheid-like structure, and plant jprimordia were observed.ure, and plant jprimordia were observed.

The rainbow hologram provides views of reconstruction with rainbow color within a large viewing zone. In our recent paper, a Fourier rainbow holographic display using diffraction grating and a white-light LED source was introduced. In this technique, the rainbow effect is realized by the dispersion of white-light source on diffraction grating, while the slit is implemented numerically by reducing the demands of the space-bandwidth product of the display. This paper presents a novel analysis on the visual perception of the Fourier rainbow holographic display using Wigner distribution. The view-dependent appearance of the image, including multispectral field of view and viewing zone, is investigated considering the observer and the display parameters. The resolution of the holographic view is also investigated. For this, a new quantitative assessment for image blur is introduced using Wigner distribution analysis. The analysis is supported with numerical simulations and experimentally captured optical reconstructions for the holograms of the computer model and real object generated with different slit size, reconstruction distance, and different observation conditions.

The objective of this experiment was to investigate the development of gastrointestinal tract and activities of pancreatic enzymes in White Roman geese. Thirty developing embryos at the 22th, 24th and 26th day of incubation and at hatching, and sixteen or eight goslings, half males and half females, at the 1, 3, 7 or 11, 14, 21 and 28 days of age were sampled, respectively. The weights of the yolk, gastrointestinal tract and intestinal length, and the activities of pancreatic enzymes were measured. Residual yolk weight decreased rapidly during late incubation and was nearly depleted at 3 days of age. The protein and energy contents in the residual yolk of goslings at 3 days of age were significantly (p<0.05) less than those at the late incubation. From 6 days before hatching to 28 days of age, the absolute weights of gizzard, proventriculus, liver, pancreas, small intestine and large intestine in goslings increased by 48, 457, 94, 2334, 89 and 76 times, respectively. The relative weights of proventriculus, gizzard, liver, pancreas, small intestine and large intestine reached peaks at 3, 3, 14, 14, 11 and 11 days of age, respectively, and then decreased gradually. However, the relative lengths of small intestine and large intestine reached peaks at 3 days of age and at hatching, respectively. The activities of pancreatic trypsin and chymotrypsin increased sharply from hatching to 14 day of age, and then decreased gradually until 21 days of age. The activity and specific activity of pancreatic amylase were increased following by age and peaked at 7 to 11 and 21 days of age, respectively. The activity and specific activity of pancreatic lipase reached a plateau from 11 to 28 days of age. These results indicate that the gastrointestinal tract and activities of pancreatic enzymes developed more rapidly than body weight through the early growing period of goslings.

The polymorphism of insulin-like growth factor-I (IGF-I) in 13 pig breeds (total n=559) was detected by PCR-Hha I- RFLP, and allele A (151 bp and 28 bp) or allele B (116 bp, 35 bp and 28 bp) were observed. In these pig breeds, it was found that European pig breeds carried high frequencies of allele B, while Chinese native pig breeds carried high frequencies of allele A. Meanwhile the role of porcine IGF-I was investigated in 117 Nanchang White pigs and 360 Large Yorkshire pigs. Eight traits about growth and carcass were recorded for analyzing the associations between IGF-I gene polymorphism and performance quantitative traits. In the Nanchang White pigs, those with AA genotype generally had higher birth weight than those with AB genotype (p<0.05), but all these genotypes had no significant effect on the other traits which had been analyzed. In Large Yorkshire pigs, those with BB genotype had higher 2 months and 6 months body weight than those with AA genotype (p<0.05), and had a thicker hind-back-fat thickness and mid-back-thickness than those with AB and BB genotypes (p<0.05). And those with BB genotype were the thinnest in Large Yorkshire. Furthermore, pigs with AA genotype had a lower lean percentage than those with AB and BB genotypes (p<0.01), and the lean percentage of those with BB genotype was the highest. Based on these results, it is possible to make the IGF-I gene locus into the application of marker-assisted selection programmes.

The Korea Institute of Oriental White Stork Rehabilitation Research (KIOWSRR) is breeding oriental white storks for residential rehabilitation in South Korea. Three oriental white storks were referred with anorexia and depression. Two storks were died before examinations and one stork was died after 1 day of fluid therapy. On necropsy, salmon-colored subcutaneous and visceral fats were examined in all storks. Multiple focal necroses on liver surface were also examined. In gizzards, many gravels and grasses were severely tangled; therefore, it produced a large mass that blocked digestive system of the storks. Small intestinal segments of the stork, which was dead after the fluid therapy, were severely adhesive. On histopathology, diffuse necroses with/without inflammation were examined in the liver, gizzard and intestine in all storks. Bile stasis was additionally examined in the liver. According to the results of the examinations, all storks were diagnosed as gizzard impaction caused by parorexia.

In this study, to examine genetic variability within a breed and genetic relationships between populations/breeds, we genotyped 606 birds from seven Japanese native chicken breeds at seven polymorphic loci of egg white proteins and compared those with Asian native chicken populations and commercial breeds. Genotyping of the Japanese native breeds showed that ovalbumin, two ovoglobulins and ovotransferrin were polymorphic, but ovomacroglobulin, ovoflavoprotein and lysozyme were monomorphic. The proportion of polymorphic loci ($P_{poly}$) and average heterozygosity ($\bar{H}$) within a population ranged from 0.286 to 0.429 and from 0.085 to 0.158, respectively. The coefficient of gene differentiation ($G_{ST}$) was 0.250 in the Japanese native chicken breeds. This estimate was higher than that of Asian native chicken populations ($G_{ST}$ = 0.083) and of commercial breeds ($G_{ST}$ = 0.169). Dendrogram and PCA plot showed that Satsuma-dori, Jitokko, Amakusa-daio and Hinai-dori were closely related to each other and grouped into Asian native chickens and that Tsushima-jidori, Nagoya and Chan (Utaichan) were ramified far from other Japanese native chicken breeds. The egg white protein polymorphisms demonstrated that the population differentiation of the seven Japanese native chicken breeds was relatively large.

This study investigated the effect of dietary paprika on the skin coloration of red- and white-colored fancy carp Cyprinus carpio var. koi, in two age groups: 0-age ($7.4{\pm}0.1$ g/fish) and 1-age ($164{\pm}2.9$ g/fish). Three isonitrogenous diets were formulated to contain 0, 5, and 10% paprika (Con, P5 and P10, respectively). Three replicate groups of 0-age fish and two replicate groups of 1-age fish were fed one of the experimental diets for 9 weeks. Survival, weight gain, and feed efficiency were not significantly affected by the dietary paprika level (P>0.05) at both fish sizes. The dietary paprika level influenced the redness ($a^*$), lightness ($L^*$), and yellowness ($b^*$) of fish skin. The $L^*$ value of the skin of the fish fed the P5 and P10 diets tended to decrease with feeding period. The skin $a^*$ value of 0-age fish (small) fed the diets containing paprika increased significantly with feeding period and was higher than that of fish fed the control diet after 3 weeks (P<0.05). However, the $a^*$ value of 1-age fish (large) fed the diets containing paprika tended to increase slightly with feeding period. At the end of the experiment, the skin total carotenoid level was increased significantly in fish of both sizes fed the P5 and P10 diets compared to fish fed the control diet. Therefore, 5% paprika powder in the diet increases the skin redness of red- and white-colored fancy carp, especially in small fish.
