There are various schemes to improve the environment of a rir in which we dwell. Among them environment color is one of formative elements that compose a city environment, the recognition about it is coming to be high gradually. A stabilized appropriate color of city environment gives a psychological social cultural effect to the people and also can be a useful method even in public information of city image, To give a citizen sensitive aesthetic and emotional satisfaction, a systematic rational design approach is necessary in an environment color plan. Hereupon, this study suggests one model of a concrete substantial color design through analyzing a present condition, for example, an existing environment, a case study about similar space, and a question investigation for finding out preference image and applying them to the color design. Through a rational systematic environment color design one can expect several effects making identity in a region, increasing a peculiar image or unity reinforcement by total application of color scheme, creating a visual environment with aesthetic characteristic, and efficiency of continuous color management system.

The present study was conducted to evaluate effect of Sauropus androgynus extract (SAE) on egg production and lipid metabolism in layer chickens. Forty-eight layers aged 42 weeks (strain RIR) were distributed to 6 treatment groups as follows. One group was fed diet without SAE as the control ($P_0$), and other five groups were fed diet plus hot water-extracted SAE at level of 9 g/kg diet ($W_9$), diet plus ethanol extracted SAE at level of 0.9 g/kg diet ($E_{0.9}$), diet plus ethanol extracted SAE at level of 1.8 g/kg ($E_{1.8}$), diet plus methanol extracted SAE at level of 0.9 g/kg ($M_{0.9}$), and diet plus methanol extracted SAE at level of 1.8 g/kg ($M_{1.8}$). It was shown that SAE inclusion significantly increased egg production (p<0.05). Methanol-extracted SAE groups had lower egg production than ethanol-extracted SAE group (p<0.05). SAE supplemented groups had better feed conversion efficiency than the unsupplemented group (p<0.05). It was shown that ethanol extracted SAE resulted in the lowest feed conversion efficiency among the SAE supplemented groups (p<0.05). SAE supplementation significantly reduced abdominal fat, gizzard surrounded fat, liver fat (p<0.05), serum triglyceride, total cholesterol, VLDL+LDL-c (p<0.01), atherogenic index (p<0.05), egg cholesterol and triglyceride (p<0.05), but it had no effect on mesenteric fat, sartorial fat and fatty liver score. In conclusion, SAE supplementation could increase egg production but reduced egg cholesterol.

This study aims to examine the early use of Da-bo tap and their transformation by analyzing the various meanings of the term pagoda in Chinese translations, the Sanskrit version of the Lotus Sutra, as well as Dabotap in the Mogao Caves of Dunhuang. In addition, we aim to highlight changes in Dabotap usage, which started out as residential spaces, but transformed into burial spaces over time. The details can be summarized as follows. First, early Buddhist monuments were usually either pagodas serving as burial places for the dead or shrines that were not. A Dabotap is a type of pagoda enshrining the body of Prabhutaratna, and was initially used as a residential space, rather than a burial place for the dead. Second, the terms stupa and caitya are clearly distinguished from each other in the Sanskrit scriptures, and stupa is also further classified into dhatu, sarisa, and atmabhava based on the object being enshrined. In Gyeon-bo-tab-pum, the preconditions for caitya to transform into stupa is presented by explaining that worshipping the space enshrining the body of Prabhutaratna is worthy of the same status as the space enshrining sarira. Third, the Mogao Caves of Dunhuang had been depicted from the Western Wei of the Northern Dynasties until the time of the Yuan Dynasty. It was used as a residential space until the early Sui Dynasty, but was used as both residence and burial places until the Tang Dynasty when pagodas were first being constructed with wheel or circles forms on top, which then gradually changed into stupa (grave towers).

An experiment was carried out with day-old "Sonali" (♂RIR$\times$♀Fayoumi) chicks to investigate the efficacy of locally made low cost brooders for brooding chicks in rural areas. Three types of indigenous brooders viz. charcoal, haricane and sawdust brooders were used for brooding chicks throughout the experimental period of 28 days. The efficiency of the brooders was observed in respect of their ability to maintain temperature, fluctuation in temperature during operation and cost effectiveness. Following initial trial of temperature maintenance for 48 h, the chicks were put under the brooder stoves and brooded up to 28 days. The experimental birds were fed on chick starter diet. Maintenance of temperature with sawdust brooders was found satisfactory and optimum for brooding the chicks at different stages of brooding and at the same time involved least cost for brooding in comparison with charcoal and haricane brooders which did not perform well in generating heat necessary for brooding and were not economically feasible for poor farmers. On the other hand, performance of charcoal brooders was better in respect of temperature maintenance during initial stage (when the brooder was started) but the temperature fluctuated rapidly, whereas fluctuation of temperature was gradual in sawdust brooders. Body weight gain and feed conversion were best in sawdust brooders. Survivability was highest in sawdust brooders and lowest in haricane brooders. Sawdust brooders may be appropriate for brooding chicks in rural areas, where electricity is not available.

A number of Korean Chicken breeds were registered in Domestic Animal Diversity Information System (DAD-IS, http://dad.fao.org/) of the Food and Agriculture Organization (FAO). Evaluation of genetic diversity and relationship of local breeds is an important factor towards the identification of unique and valuable genetic resources. Therefore, this study aimed to analysis the genetic diversity and relationship of 22 Korean Chicken breeds using 12 microsatellite (MS) markers. The mean number of alleles for each variety was 5.52, ranging from a 3.75 (Leghorn F; NF) to a 7.0 (Ross). The most diverse breed was the Hanhyup3 (HCC), which had the highest expected heterozygosity (H_Exp) (0.754) and polymorphic information content (PIC) (0.711). The NF was the least diverse population, having the lowest H_Exp (0.467) and PIC (0.413). As a result of the principal coordinates analysis (PCoA) and factorial correspondence analysis (FCA) confirmed that Hy-line Brown (HL) and Lohmann Brown (LO) are very close to each other and that Leghorn and Rhode Island Red (RIR) are clearly distinguished from other groups. Thus, the reliability and power of identification using 12 types of MS markers were improved, and the genetic diversity and probability of individual discrimination were confirmed through statistical analysis. This study is expected to be used as basic data for the identification of Korean chicken breeds, and our results indicated that these multiplex PCR marker sets will have considerable applications in population genetic structure analysis.

Microsatellite markers have been a useful genetic tool in determining diversity, relationships and individual discrimination studies of livestock. The level of genetic diversity, relationships among two Korean indigenous chicken brand populations (Woorimatdag: WR, Hanhyup3: HH) as well as two pure populations (White Leghorn: WL, Rhode Island Red: RIR) were analyzed, based on 26 MS markers. A total of 191 distinct alleles were observed across the four chicken populations, and 47 (24.6%) of these alleles were unique to only one population. The mean $H_{Exp}$ and PIC were estimated as 0.667 and 0.630. Nei's $D_A$ genetic distance and factorial correspondence analysis (FCA) showed that the four populations represented four distinct groups. However, the genetic distance between each Korean indigenous chicken brand (WR, HH) and the pure population (WL, RIR) were threefold that among the WR and HH. For the STRUCTURE analyses, the most appropriate number of clusters for modeling the data was determined to be three. The expected probabilities of identity among genotypes of random individuals (PI) were calculated as $1.17{\times}10^{-49}$ (All 26 markers) and $1.14{\times}10^{-15}$, $7.33{\times}10^{-20}$ (9, 12 with the highest PI value, respectively). The results indicated that the brand chicken breed traceability system employing the own highest PI value 9 to 12 markers, and might be applicable to individual identification of Korean indigenous chicken brand.

Nano-sized PtRu-Ni/VC and PtRu-Sn/VC electrocatalysts were synthesized by a one-step radiation-induced reduction (RIR) (30 kGy) process using distilled water as the solvent and Vulcan XC-72 as the supporting material. The obtained electrocatalysts were characterized by transmission electron microscopy (TEM), scanning electron microscope energy dispersive spectroscopic (SEM-EDS), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS), respectively. The catalytic efficiency of electrocatalysts was examined for oxygen reduction, MeOH oxidation and CO stripping decreased in the following order, Hydrogen stripping : PtRu-Sn/VC > PtRu-Ni/VC > PtRu/VC$^{(R)}$ (E-TEK). MeOH oxidation : PtRu-Sn/VC > PtRu-Ni/VC > PtRu/ VC$^{(R)}$ (E-TEK). Unit cell performance : PtRu-Sn/VC > PtRu-Ni/VC > PtRu/VC$^{(R)}$ (E-TEK) catalysts.

Thyroid hormone (TH) plays a role in growth of the poultry. Thyroid-stimulating hormone (TSH) stimulates production and distribution of TH, and is a heterodimer which is formed by ${\alpha}$- and ${\beta}$-subunits. Most of TSH activity is known to rely on ${\beta}$-subunit. TSH-${\beta}$ gene is located on chicken chromosome 26 and associated with growth performances. Therefore, this study aimed to investigate the association of TSH- ${\beta}$ SNP (G1031C) with economic traits (layday, layw, layno, bw150, bw270, layw270) in Korean Native Black chicken, Rhode Island Red and Cornish. Allele frequency of GG genotype in Rhode Island Red (RIR) was found to be 1.00 in this study. A significant effect was only observed on body weight at day 150 in Cornish. In Cornish, body weights of chicken with the CC genotype ($302.15{\pm}6.336$) were significantly higher than that of the GG genotype ($294.56{\pm}4.537$) (p<0.05). These findings suggest that the G1031C SNP of TSH-${\beta}$ gene can be used for improvement of growth-related traits in Cornish.
