Research in low cost feeds with high nutritional value and immunogenicity is important to reduce production cost and increase yields in the shrimp industry. In this study, immunostimulants of bacterial origin (peptidoglycan and lipopolysaccharides) and egg white were incorporated in shrimp diets as feed additives to determine the growth, survival and tolerance of Penaeus monodon to white spot syndrome virus (WSSV). Although the results obtained were not statistically significant (p>0.05) among the treatments, shrimp fed with bacterial additives and egg white showed higher weight gain, specific growth rate and survival than those fed on commercial shrimp diet. Shrimp fed with artificial diet showed 100% mortality when challenged with WSSV. However, shrimp fed on peptidoglycan supplemented diet had higher survival than their counterpart, whereas shrimp fed on egg white supplemented diet had a higher specific growth rate and better tolerance when challenged with WSSV. Further studies are required to determine the effectiveness and optimization of bacterial strains and egg white as feed additives to increase production and enhance the shrimp immune response to diseases.

In the present study, an optimum protease was selected to hydrolyze the egg white liquid protein for the antioxidant peptides. Alcalase treatment yielded the highest amount of ${\alpha}$-amino groups (15.27 mg/mL), while the control (no enzymatic hydrolysis) showed the lowest amount of ${\alpha}$-amino groups (1.53 mg/mL). Alcalase also gave the highest degree of hydrolysis (DH) value (43.2%) and was more efficient for egg white liquid hydrolysis than the other enzymes. The Alcalase hydrolysate had the highest radical-scavenging activity (82.5%) at a concentration of 5.0 mg/mL. The conditions for enzymatic hydrolysis of egg white liquid with Alcalase were selected as substrate : water ratio of 2:1. Five percent Alacalse treatment did not show significant (P>0.05) increases of DH and ${\alpha}$-amino nitrogen content after 24 hhydrolysis. Thirty two hour-hydrolysis with 5% Alcalase is sufficient to make antioxidative egg white liquid hydrolysate from egg white liquid. DPPH and ABTS radical-scavenging activities were significantly (P<0.05) higher after enzymatic digestion. These results suggest that active peptides released from egg-white protein are effective radical-scavengers. Thus, this approach may be useful for the preparation of potent antioxidant products.

In this paper, multiheterostructure white organic light-emitting device was fabricated by vacuum evaporation. The structure of white organic light-emitting device is ITO/CuPc/TPD/DPBi:DPA/$Alq_3/Alq_3$:DCJTB/BCT/$Alq_3$/Ca/Al. Three primary colors are implemented with DPVBi, Alq$_3$and DCJTB. The maximum EL wavelength of the fabricated white organic light-emitting device is 647nm. And the CIE coordinate is (0.33, 0.33) at 13 V. In the fabrication of white organic light-emitting devices with DCJTB, $Alq_3$, DPVBi, the EL spectrum has two peaks at 492nm, 647nm. Two peaks appeared because the blue light is combined with green light. The maximum wavelength of red light is not changed with applied voltage. After voltage applied, for the first time, the electrons met the holes in the red emission layer and emitted red light. And then the electrons moved to the green emission layer, and blue emission layer continuously. Finally, when all of the emission layer activated, the white light is emitted.

Spurred by the ongoing globalization, an increase in mobility has diversified migrant categories and strengthened intercultural rapport. Alongside the "traditional" migrants, "White" (Caucasian) individuals are coming into greater focus of migration studies as "lifestyle migrants". Although White migrations are not a new phenomenon, the deep-seated idea of White supremacy continues to play an important role in contemporary intercultural communication, awarding Whites across communities a "cosmopolitan" status of highly educated cultural elites. As such, the focus of this research is on highly skilled White European migrants, on their subjective experiences of integration in Japan, and whether they perceive Whiteness as an obstacle or an advantage in this process, if integration is desired at all. To discern the connection between race and integration, this research investigates the non-White majority society of Japan as it has established racial hierarchies according to the Western models, consequently influencing the status of its contemporary White immigrants. Privileged, yet singled out as racial and cultural role models, White Europeans' integration seemingly becomes nearly impossible. The data obtained in fifteen semi-structured interviews confirms that Whiteness grants advantages when entering the Japanese job market, but remains an obstacle in everyday community integration. European professionals do not feel accepted and abandon efforts to integrate, if such were made, retreating into "cosmopolitan islets" wherein they renegotiate their White European identities.

The Imperial Road is Jean Rhys s unfinished manuscript, rejected by publishers for its openly racist tone. Although it describes Rhys s actual visit to Dominica in 1936, it is not a transparent recollection of the travel but a recreation informed by racial dynamics of the 1970s when she wrote the text. This paper examines the manuscript as a troubled (and troubling) response to what Rhys perceived as racial rejection from Dominica at the wake of political independence. Rhys s representation of white Creole womanhood significantly depends on an interwoven configuration of racial dynamics and sexual politics, where an oppressive white European man facilitates a white Creole woman s cross-racial identification with Afro-Caribbeans. However, the political and literary landscape of the West Indies in the 1970s made such cross-racial identification untenable. As a result, The Imperial Road is full of disturbing racial hatred, prejudice, and resentment. And yet, it also reflects Rhys s honest and serious concern over a white Creole s racial identity in postcolonial Dominica, raising a difficult question: How would a postcolonial age change a white Creole identity that belongs neither to the colonized nor to the colonizer (or both)? In The Imperial Road, unable to identify with Afro-Caribbeans, the white Creole is disoriented in time and space, lost at home, stuck between the past and the present, not knowing how to participate in a postcolonial homeland. Through the narrator s racial disorientation, The Imperial Road exposes the white Creole s fundamental dependence on other Creoles.

Korean people have revered the white color and enjoyed wearing white clothes. Various kinds of white clothes have been worn by the Korean people, ranging from everyday wear(便服), and scholar's robe(深衣) for the upper class, to religious costumes like Buddhist monk's robe(僧服), shaman costumes(巫服) and costumes for ancestral rites(祭服), or mourning(喪服). There have been many differing opinions by historians regarding the background of this Baekeuihosang(白衣好尙, the preference for white clothing) tradition and even now, it is frequently being discussed. This study aims to consider and discuss the background of this Baekeuihosang tradition, focusing on Chang-seon Yoo's Baekeuigo(白衣考, the consideration of white clothing), which was published in Dong-A Ilbo in 1934. The purposes of studying literature such as the Baekeuigo is to analyze the arguments on the origin of Baekeuihosang, to analyze Chang-seon Yoo's claim of its origin, and to discuss the culture of Baekeuihosang. Chang-seon Yoo claimed that the existing discussions on the background of Baekeuihosang based on the lack of dyes, or undeveloped technique, economic privation and national control strayed from historical facts, according to literature review. It is not worth discussing the farfetched arguments such as the use of costumes for ancestral rites as everyday wears, or the nation of sorrow. Baekeuihosang tradition mostly originated from the effects of many religions and the taste for innocence, or naturalness. White clothes were infused with the sorrow and emotion of Korean people and were also worn to show resistance to foreign power as symbols of ethnicity. Therefore, there should be a new view of the discussion of white clothes and Korean aesthetic sense, away from the logic distorted by the Japanese colonial view of history.

To investigate the genetic diversity of seven Chinese indigenous meat goat breeds (Tibet goat, Guizhou white goat, Shannan white goat, Yichang white goat, Matou goat, Changjiangsanjiaozhou white goat and Anhui white goat), explain their genetic relationship and assess their integrity and degree of admixture, 302 individuals from these breeds and 42 Boer goats introduced from Africa as reference samples were genotyped for 11 microsatellite markers. Results indicated that the genetic diversity of Chinese indigenous meat goats was rich. The mean heterozygosity and the mean allelic richness (AR) for the 8 goat breeds varied from 0.697 to 0.738 and 6.21 to 7.35, respectively. Structure analysis showed that Tibet goat breed was genetically distinct and was the first to separate and the other Chinese goats were then divided into two sub-clusters: Shannan white goat and Yichang white goat in one cluster; and Guizhou white goat, Matou goat, Changjiangsanjiaozhou white goat and Anhui white goat in the other cluster. This grouping pattern was further supported by clustering analysis and Principal component analysis. These results may provide a scientific basis for the characteristization, conservation and utilization of Chinese meat goats.

Decoys for automatic jigging machines, the body part of a squid hook, have been developed in small and existing sizes in consideration of squid food, color blindness, and retinomotor responses and in utilization of pearl pigment, PP of high transparency, and combined mixture. In comparison of the developed silver-white decoy and existing decoys, the optical characteristics were examined, and the fishing performance of small size silver-white squid hooks was assessed in application of 4 fishing boats with the squid automatic jigging machine and metal halide fishing lamp in July, 2012. The luminances of the three squid hook colors-green, dark green and silver-white-increased as the intensity of illumination increased. Among these, the increase of silver-white was particularly distinguished. As to the average contrast of squid hooks, that of silver-white was 10.33, which was the highest, and then green 1.86 and dark green -0.10 in the order. As to the fishing performance of the silver-white hook, that of the 202 Geumyeong-ho and 101Yongjin-ho which caught squids were similar to that of the existing green hook and was relatively low in the case of the Dongbu-ho. However, that of the Haengbok-ho which caught relatively small squids whose average length was 19.9cm and installed silver-white hook in all automatic jigging machines was significantly excellent. In order to enhance the fishing performance of small size silver-white hooks, therefore, it would be effective to install in every automatic jigging machines of fishing boat and to start fishing before July by which small squids are caught.

We prepared 8 samples of non-silver and silver-added master alloys containing silicon to confirm the existence of nickel-silicides. We then prepared products made of 14K and 18K white gold by using the prepared master alloys containing 0.25, 0.35, and 0.50 wt% silicon to check for nickel release. We then employed the EN 1811 testing standard to investigate the nickel release of the white gold products, and we also confirmed the color of the white gold products with an UV-VIS-NIR-color meter. We observed $NiSi_x$ residue in all master alloys containing more than 0.50 wt% Si with EDS-nitric acid etching. For the white gold products, we could not confirm the existence of $NiSi_x$ through XRD after aqua-regia etching. In the EN 1811 test, only the white gold products with 0.25 wt% silicon master alloys successfully passed the nickel release regulations. Moreover, we confirmed that our white gold products showed excellent Lab indices as compared to those of commercial white gold ones, and the silver-added master alloys offered a larger L index. Our results indicate that employing 0.25 wt% silicon master alloys might be suitable for white gold products without nickel-silicide defects and nickel release problems.
