Among elements of play, there are puppets performances and shadows performance which are replacing actors by puppets and shadows. Puppet performance is characteristic of expressing various movements and symbols at its conveniences by the reduced models of human form with various materials. Shadow performance is realized in various colors that cannot be discovered in other countries by expressing mysterious cubic effect in reflecting the light against various forms. Mansukjung Nolum is a unique shadow performance that has been inherited in Korea. There are found many shadow performances inherited in the northern Europe and South-eastern Asia. Recently the silhouette animation in application of shadow performance is made. In the northern Europe and South-eastern Asia, they performed in white and black color while Mansukjung Nolum is performed in natural colors. Since they adopted the leather materials for making puppets, their opaque feature cannot reflect the colored light. But in Korea we adopted the specially colored semi-transparent Korean paper, which gives the colored shadows to spectators. Mansukjung Nolum consists of three acts for arousing attention of fallen monks destroying the teaching of Buddha. Seosanbakchumji Nolum is a puppet performance inherited in a village in Seosan, Choongnam instead of wandering artists. The story and form of performance in Namsadangpae's puppet play is mostly similar to it, but it is woven by its villages natural environment and specific dialects, reflecting their consciousness in mind. The villagers made the puppets and manipulate them in communicating their wisdom of life between them. Parkchumji Nolum is a kind of integral art combining puppet manipulation, witticism, songs and dances. The hero of Parkchumji discloses the social and structural conflicts of feudalism, in arousing the spectators' rich attention of self-awareness and lessons.

To become a person that is suitable to the 'High-Touch' generation where emotion takes over, we can focus on 6 skill including design, story, harmony, empathy, play, and meaning. Among these skills, harmony with design was chosen as the most important skill. Design can be seen as the basic element of all business, but it will be difficult to match the flow of the future Sensibility and intuitive generation with just the modern design that has been made based on reasonable and objective information and knowledge. This study suggests system and standardization of Sensibility surface processing design that satisfies great quality, attractive quality and Sensibility quality by applying surface processing design of product and Sensibility cognitive factors felt by the consumer by setting differentiated strategy and CMF (Color, Material, Finishing) understanding along with the importance of design materials in primary aspect. By considering the efficacy/characteristic of new surface processing characteristic/differentiation/possibility of implementation according to setting direction of differentiated CMF strategy per type of parts applied to the product, visual surface processing sample was implemented. Through this, it is expected that practical communication connected tool and Sensibility surface processing design's strategic access framework can be applied by understanding and sharing comprehensive elements such as target product, part type, applied material, applied surface processing, surface color, surface texture, and implementing feeling to environments such as designers, CMF designers, surface processing experts, and engineers in IT, electronics, and other areas. when developing a product.

In photoreceptor cells, light activates visual pigments consisting of a chromophore (retinal) and a protein moiety (opsin). Activated visual pigments trigger an enzymatic cascade, called phototransduction cascade, in which more than ten phototransduction proteins are participating. Two types of vertebrate photoreceptor cells, rods and cones, play roles in twilight and daylight vision, respectively. Cones are further classified into several subtypes based on their morphology and spectral sensitivity. Though the diversities of vertebrate photoreceptor cells are crucial for color discrimination and detection of light over a wider range of intensities, the molecular mechanism to characterize the photoreceptor types remains unclear. We investigated the amino acid sequences of about 50 vertebrate opsins, and found that these sequences can be classified into five fundamental subfamilies. Clear relationships were found between these subfamilies and their characteristic spectral sensitivities. In addition to opsins, we studied other phototransduction proteins. The amino acid sequences of phototransduction proteins can be classified into a few subfamilies. Even though their spectral sensitivity is considerably different, cones fundamentally share the phototransduction protein isoforms which are different from those found in rods. It is suggested that the difference in phototransduction proteins between rods and cones is responsible for their sensitivity to light. Isoforms and their selective expression may characterize individual photoreceptor cells, thus providing us with physiological functions such as color vision and daylight/twilight visions.

The objective of this study was to investigate the antioxidant activity of Korean yam (Dioscorea batatas $D_{ECNE.}$) by different extraction solvents including 70% methanol, 70% ethanol and chloroform-methanol mixture (CM, 2:1, v/v). Raw yam was analyzed for its color property, total phenol content and antioxidant activity. Yam possessed high $L^*$ value and $H^{\circ}$ value, which were $81.64{\pm}2.59$ and $83.36{\pm}0.15$, respectively. Raw yam was found to have great antioxidant activity evaluated through ABTS [2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt] radical scavenging activity, DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, reducing power, and ferric reducing antioxidant power. Total phenol contents of various extracts from raw yam increased in the following order: 70% methanol extract ($37.62{\pm}0.88mg\;CAE/g$), 70% ethanol extract ($43.38{\pm}0.66mg\;CAE/g$) and CM extract ($67.17{\pm}0.12mg\;CAE/g$), respectively. The same trend was also could be found in the ABTS radical scavenging activity, DPPH radical scavenging activity and ferric reducing antioxidant power assays. These results implied that Korean yam might play an important role in antioxidation and serve as the bio-health functional food to take a good part in prevention of human diseases and aging.

Background: Dietary fats can alter the deposition and distribution of body fats in ruminants. The deposition and distribution of body fat play a vital role in the quality of ruminant carcasses and are of great commercial value since they influence the profitability and consumer acceptability of ruminant meat. The current study examined the effects of dietary blend of 80 % canola oil and 20 % palm oil (BCPO) on carcass characteristics, meat yield and accretion of fatty acid (FA) in subcutaneous, omental, perirenal, and mesentery adipose depots and m. supraspinatus (SS) in goats. Methods: Twenty four Boer crossbred bucks (BW $20.54{\pm}0.47kg$) were randomly assigned to diets containing on DM basis 0, 4 and 8 % BCPO, fed for 100 d and harvested. Results: Diet had no effect (P > 0.05) on slaughter weight, dressing percentage, carcass and non-carcass components, meat yield, color, moisture and carotenoid contents and weight of adipose tissues in goats. The proportion of C18:1n-9 and cis-9 trans-11 CLA in the omental, perirenal and SS was higher (P < 0.05) in goats fed 4 and 8 % BCPO compared with the control goats. Dietary BCPO reduced (P < 0.05) the proportion of C14:0 in the omental, perirenal and mesentery depots, C18:0 in the perirenal depot, C16:0 in the SS and C16:1n-7 in the SS, omental and perirenal tissues. Dietary BCPO enhanced the proportion of C18:1 trans-11 Vaccenic and C18:3n-3 in SS and C20:5n-3 in SS and mesentery depot. No significant changes were found in the FA composition of subcutaneous depot. Conclusions: Results indicate that dietary BCPO can be utilized to alter the FA composition of adipose tissues without detrimental effects on carcass characteristics in goats. Nonetheless, dietary BCPO is not an effective repartitioning agent for body fats in goats.

When it comes to clothing design, after the mid 20th century some internationally renowned designers began to recognize the pivotal role clothing materials play in attracting the hearts of customers. Accordingly, they started to take advantage of new clothing materials in the sector of clothing design. While the theme of fashionable clothing products shifts from style and color to clothing materials, fashion designers place the quality of materials at the center of clothing designs. Fashion designers also realize that good quality of materials should be used to boost the value of products as well as to satisfy the conditions of creativity, practicality and aesthetics. In particular, as the non-apparel industry in which clothing materials are the most important aspect between fashionable color, silhouette and details is enhancing their attention to develop various materials in order to meet the needs of customers, the fashion industry places a high premium on textile design which is the pinnacle of expressing emotion on clothing materials. In addition, the industry raises awareness of developing more sophisticated and differentiated materials. Our thesis covers the way how to apply $moir{\acute{e}}$ pattern to clothing design on the basis of research. In order to put that research into practical use, we produced textiles which effectively display $moir{\acute{e}}$ pattern. Before this process, we tried to ensure that radial grating created $moir{\acute{e}}$ pattern effects. To this end, the weaving process was applied, depending on whether light can penetrate textiles or not. Then, we manufactured test-products using $moir{\acute{e}}$ pattern.

The systematic study of the future began with curiosity and imagination about the future; a unique trait of human mental effort-and this seems to be based on the idea that the future can be different depending on current choices or effort. In this sense, it would be seemly to encourage more interest and academic study on the progress of future fashion. In this study, we examine recent changes of fashion material; e.g. that which science and technology have more impact and importance in futuristic fashion since the 1990�s. The period analysed is from the1990's to the present and related data from recent fashion collections and fashion books has also been included The current prediction of the future is largely based on what was formed between the 19th Century and the 20th Century which has persisted until now and has been influenced by the view that science will play a bigger role in the future. This is especially reflected in fashion which chiefly represents material culture. New materials used for fashion are strong and permanently durable, in addition to being very light, thin, flexible, hygienic, ecological and comfortable to wear-almost like a second skin. These fashionable new materials roughly function in two different ways according to external and internal characteristics. First, they cause external change. Second, they exemplify or allow new functions. Examples of external change are the use of silver color, achromatic color, metallic material, smooth-to-the-touch shiny material and the use of luminous material. Examples of the extended function of clothing through the use of new materials are the use of conducting thread, the use of special material for blocking & opening and the use of material which changes colors as the surroundings change. These days, the use of new material which changes its appearance is a novelty unique to the fashion world but we also expect to witness the debut of diverse new materials with extended inner functions.

The purpose of this study was to know how helmet and armor was reinterpreted in historical play by considering general concept and type of old helmet and armor from the aspect of costume history and comparing the helmet and armor types of TV historical plays, Yeongaesomun and Taewangsasingi, whose historical backgrounds were based on the age of Goguryeo. The helmet and armor type shown in Yeongaesomun was reinterpreted as the one, which is close to historical investigation, by reappearing lamellar armor and jongjangpanju(helmet made of slim, long plate) shown in Goguryeo wall painting. The helmet and armor type shown in Taewangsasingi expresses fantastic helmet and armor by adding fantastic factor regardless of historical investigation. The study result reveals that there are several common characteristic factors between the helmet and armors of two historical plays. First, there was a classification in the display of character and story. The helmet and armor type shown in Yeongaesomun classified color and detail design depending on lamellar armor or character. In Taewangsasingi, the helmet and armor was manufactured depending on character's nature and the chain armors, which are lighter than existing helmet and armors, were usual. Second, they escaped from the historical investigation about traditional helmet and armor. In Yeongaesomun, myeonggwangae(a type of armor), which might be popular, was not expressed and Taewangsasingi is free from an imperative idea of historical investigation by manufacturing helmet and armor referring to that of ancient Rome age. The modern sense was reflected to increase dramatic effect. The helmet and armor of Yeongaesomun provides modern feeling by using stainless steel material and modern color arrangement and that of Taewangsasingi is designed in modern, splendid way as it aimed at game development from the planning step.

We investigate the connection between the presence of bars and AGN activity, using a volume-limited sample of ~6,000 late-type galaxies with axis ratio b/a > 0.6 and $M_r=-19.5+5logh$ at low redshift (0.02 < z ${\leq}$ 0.055), selected from Sloan Digital Sky Survey Data Release 7. Although bars are believed to play an important role in fueling AGNs, it is still an open question whether AGN activity is connected with the presence of bars. We find that the bar fraction in AGN-host galaxies (44.1%) is 2.5 times higher than in non-AGN galaxies (17.6%), implying an AGN-bar connection. However, this trend is simply caused by the fact that AGN-host galaxies are on average more massive and redder than non-AGN galaxies since the bar fraction increases with u-r color and velocity dispersion. When AGN-host and non-AGN galaxies with fixed u-r color and velocity dispersion are compared, the excess of bar fraction in AGN-host galaxies disappears. Among AGN-host galaxies we find no strong difference of the Eddington ratio distributions between barred and non-barred systems. These results indicate that AGN activity is not directly connected with the presence of bars.

We examined the cause of albinism in a hatchery population of flounder in terms of environmental and nutritional factors, including the effects of light intensity (130-12,300 lux), photoperiod (12L/12D or 24L/0D), tank substrate (concrete or fiber-reinforced polymer), tank color (white or dark green) and supplement with enriched live food, and also compared the growth of normal and albino fry under both 12L/12D and 24L/0D. Further to, normalization of the skin pigmentation pattern on the ocular side has been juvestigated after rearing the albino fry for 2 years after their identification and classification and found that, light intensity did not play a critical role in the development of normal pigmentation or albinism in the flounder. By contrast, the photoperiod was a weak inducer of albinism in the flounder. Tank substrate and color also affected the hypomelanosis on the ocular side of the flounder fry. The choice and supplementation of enriched live foods could drastically reduce the incidence of albinos in hatcheries. On comparing the growth of normal and albino fry, while there was no difference between the groups under 24L/0D, the growth of the albino flounder was slower under 12L/12D. Although coloration resulting from xanthophore and melanophore, but not iridophores, occurred on the ocular side, evidence of albinism remained on the ocular side of flounders.
