This study was carried out to investigate the effects of various dietary lipid sources on the growth performance, body composition, and fatty acid profiles of juvenile fancy carp (Cyprinus carpio var. koi). Three replicate groups of fish (initial mean body weight, 15.1±0.18 g) were fed one of five experimental diets containing fish oil (SLO), soybean oil (SO), linseed oil (LO), lard (LA), or a mixture of SLO, SO, and LO (Mix) for 8 weeks. Fish fed the LA diet gained less weight than did fish fed the LO diet. The feed efficiency and protein efficiency ratio of fish fed the LA and Mix diets were lower than those of fish fed the SO and LO diets. The body lipid content of fish fed the SO diet was lower than those of the other groups. Whole-body fatty acid compositions reflected the fatty acid compositions of dietary lipid sources. Fish fed the SO diet had high concentrations of linoleic acid and arachidonic acid, whereas fish fed the LO diet were rich in linolenic acid. Fish fed the SLO diet had significantly higher levels of eicosapentaenoic acid and docosahexaenoic acid compared with fish fed the SO, LO, and LA diets. The results of this study suggest that SO or LO could be used as a replacement for SLO in the diets of juvenile fancy carp without any negative effects on growth and feed utilization when the dietary essential fatty acid requirements are satisfied for juvenile fancy carp.

This study was conducted to investigate the effects of Spirulina level in the diet on growth and skin color of red- and white-colored fancy carp Cyprinus carpio var. koi at different feeding periods. Five experimental diets (designated as Con, S5, S9, S13 and S17) were prepared to contain 0, 5, 9, 13 and 17% Spirulina. Each experimental diet was fed to two replicate groups of fish (6.6 g/fish) to visual satiation three times a day for 12 weeks. Weight gain and feed efficiency of fish were not affected by dietary Spirulina level. The values of redness ($a^*$), lightness ($L^*$) and yellowness ($b^*$) of the fish skin were influenced by dietary Spirulina level at different feeding period. The $L^*$ value of skin in the fish fed S9, S13 and S17 diets tended to decrease with feeding period. The skin $a^*$ value of the fish increased significantly with feeding period and dietary Spirulina level. The skin $a^*$ value of the fish fed the diets containing 5-17% Spirulina was higher than that of fish fed control diet at 6 and 12 weeks of feeding. The skin $a^*$ value and total carotenoids of the fish fed the S17 diet was the highest among groups. Based on the results of this study, it can be concluded that dietary inclusion of Spirulina powder could increase the skin redness of red- and white-colored fancy carp.

The yarn company needs to conform to the consumers' sensibility, which has become diverse, in developing its yarn, which fixes the matter property and the sensibility in knit product. In particular, the development of fancy yarn, which is expected to have great influence upon the sensibility of material due to being a diverse form of knit yarn, may increase activation of the knit industry. Eight different fancy yarns were chosen: loop, Ratine, tam tam, fur 1, fur 2, chenille, ladder and tape yarn. The manufacturing methods of these yarns are all different. The sensibility was evaluated through a questionnaire targeting 60 women in their 20s of the expert group. Factor analysis, reliability, correlation analysis, ANOVA, Duncan, and regression analysis were carried out by using SPSS 12.0. First, according to the results of analyzing the sense factor, three factors were extracted: 'inflexibleness/rugged', 'lightweight' and 'smooth'. 'Activity', 'grace' and 'purity' were extracted in regard to the sensibility factor. H3(tam tam) sample showed high value in all of preference, purchase intention and word-of-mouth intention. To increase consumers' preference, purchase intention, and word-of-mouth intention, its effect is thought to be likely to be possibly seen only when increasing the factor of pure and simple grace and when reducing the hard and stiff inflexibleness/ruggedness sense. It is expected to be likely to possibly secure marketability as knit product, which has product competitiveness, given the product planning in a company of producing knit.

Current global textiles and fashion industries have gradually shifted focus to high value-added, high sensibility, and multi-functional products based on new human-friendliness and sustainable growth technologies. Textile design CAD systems have been developed in conjunction with computer hardware and software sector advances. This study compares the patterns or images of actual woven fabrics and virtual fabrics prepared with a textile design CAD system. In this study, several weave structures (such as fancy yarn weave and patterns) were prepared with a shuttle loom. The woven textile images were taken using a CCD camera. The same weave structure data and yarn data were fed into a textile design CAD system in order to simulate fabric images as similarly as possible. Similarity Index analysis methods allowed for an analysis of the index between the actual fabric specimen and the simulated image of the corresponding fabric. The results showed that repeated small pattern weaves provide superior similarity index values than those of a fancy yarn weave that indicate some irregularities due to fancy yarn attributes. A Complex Wavelet Structural Similarity(CW-SSIM) index resulted in a better index than other methods such as Multi-Scale(MS) SSIM, and Feature Similarity(FS) SSIM, across fabric specimen images. A correlation analysis of the similarity index based on an image analysis and a similarity evaluation by panel members was also implemented.

A feeding trial was conducted to investigate the effects of dietary carotenoid source and level on growth and skin color of red- and white-colored fancy carp Cyprinus carpio var. koi. Nine experimental diets (designated as CON, SP5, SP10, AS50, AS100, CA50, CA100, PA5 and PA10) were formulated to contain 5-10% Spirulina powder, 5-10% paprika powder, 50-100 ppm astaxanthin and 50-100 ppm canthaxanthin. The CON diet without supplementation of carotenoid source was considered as the control diet. Each experimental diet was fed to three replicate groups of fish (3.6 g/fish) to visual satiation three times a day for 8 weeks. Survival, growth and feed efficiency of fish were not significantly affected by dietary inclusion of carotenoid source and level (P>0.05). After 8 weeks feeding period, the values of $a^*$, $L^*$and $b^*$ of fish skin were significantly changed by dietary carotenoid source (P<0.05), but not carotenoid level. The $a^*$ value of fish fed the diets containing CA and PA was higher than control and SP diets (P<0.05). Based on the results of this study, it can be concluded that dietary inclusion of 50 ppm canthaxanthin or 5% paprika powder could increase the redness of red-and white-colored fancy carp fingerling.

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.

This study was conducted to investigate the growth and skin color of red- and white-colored fancy carp Cyprinus carpio var. koi juvenile reared at different water temperatures (21, 24, 27, and $30^{\circ}C$) for eight weeks. Two experimental diets were prepared to contain 10% Arthrospira platensis or 10% Arthrospira pacifica powder. After the feeding trial, survival was 100% in all group. Weight gain of fish reared at 24, 27, and $30^{\circ}C$ was higher than $21^{\circ}C$ group. Feed efficiency was not affected by water temperature and dietary Arthrospira sp. Daily feed intake tended to increase with water temperature. The $a^*$ value of skin coloration was affected by Arthrospira sp., but not by water temperature. Fish fed the diet containing A. pacifica powder reared at $27^{\circ}C$ had the highest $a^*$ value among the groups. Total carotenoids were highest in fish fed the diet containing A. pacifica powder reared at $21^{\circ}C$. Based on the results of this study, we conclude that 24-$30^{\circ}C$ water temperature was the optimal range for growth, and dietary inclusion of A. pacifica improved the skin redness of red- and white-colored fancy carp reared at $27^{\circ}C$.

Blood samples were collected from eight native Japanese breeds of chickens (Miyadi-dori, Ohiki, Onaga-dori, Shoukoku, Tosa-Jidori, Tosa-Kukin, Toutenkou and Uzurao) and two foreign breeds of chickens (White Leghorn and Rhode Island Red) to examine the genetic variability and relationships among the breeds by using a microsatellite DNA technique. Except for the Shoukoku breed, the other Japanese chicken breeds all originate from Kochi Prefecture. Ohiki, Onaga-dori, Tosa-Jidori, Toutenkou and Uzurao are fancy fowl, and Miyadi-dori and Tosa-Kukin are utility fowl. Among the fancy fowl, Ohiki, Onaga-dori, and Toutenkou males have thick and long feathers in the saddle and tail. Genetic variabilities of the 20 microsatellites examined, varied depending on the breed: the mean number of alleles per locus ranged from 2.05 (Miyadi-dori) to 3.90 (Rhode Island Red); proportion of polymorphic loci ranged from 0.75 (Miyadi-dori) to 1.00 (Rhode Island Red, Shoukoku and Uzurao); and mean expected heterozygosity ranged from 0.330 (Miyadi-dori) to 0.607 (Rhode Island Red). Unique microsatellite alleles were detected in each breed. Using the neighbour-joining method, phylogenetic trees were constructed based on the genetic distances of D$_{A}$ and D$_{ST}$. Among the breeds originating from Kochi Prefecture, fancy and utility breeds belonged to different clusters. Among the fancy breeds, those having thick and long feathers in the tail and saddle showed a close genetic relationship to the Shoukoku breed, which also has thick and long feathers in the tail and saddle.

A feeding trial was conducted to investigate the effects of dietary carotenoids sources on growth and skin color of red- and white-colored fancy carp Cyprinus carpio var. koi. Nine experimental diets (designated as Con, CP, PA, SP, OP, MB, TO, BE and PO) were formulated to contain Carophyll Pink, red paprika, Spirulina, Opuntia, mandarin bark, tomato, beet and Porphyra, respectively. Each experimental diet was fed to two replicate groups of fish (22.9 g/fish) to visual satiation three times a day for 8 weeks. Weight gain and feed efficiency of fish fed the diets containing Spirulina or Opuntia were higher than those of fish fed the control diet (P<0.05). The values of $a^*$, $L^*$ and $b^*$ of fish skin were significantly changed by dietary carotenoids sources (P<0.05). The $a^*$ values of fish fed the diets containing Carophyll Pink, red paprika and Spirulina were higher than those of fish fed other diets (P<0.05). The skin total carotenoids of fish fed the diets containing Spirulina and Opuntia were higher than those of others (P>0.05). Based on the results of this study, it can be concluded that dietary inclusion of red paprika and Spirulina pacifica could increase the skin redness of red- and white-colored fancy carp.

This study assesses the formaldehyde and TVOC emissions from bio-composites with attached fancy veneer manufactured using wood flour and polypropylene (PP) measured using the Field and Laboratory Emission Cell (FLEC) method and 20 L small chamber method. To determine and compare the effects of the adhesive, samples were prepared with different manufacturing methods. In the FLEC result, the formaldehyde emission level of the bio-composites with attached veneer by hot-press was the lowest than pure bio-composite and bio-composite attached veneer using adhesive. The TVOC emission levels are similar to the formaldehyde emission. The TVOC emission level is very low in all of the samples except fancy veneer that is attached with bio-composites using adhesive. The TVOC emission varies depending on how attaching fancy veneer. The results of the 20 L small chamber method were very similar to those obtained with the FLEC, but the correlation was not perfect. However, the FLEC method requires a shorter time than the 20 L small chamber method to measure the formaldehyde and TVOC emissions. The internal bonding strength exceeded the minimum value of $0.4N/mm^2$ specified by the KS standard. All of the bio-composites with attached veneer satisfied the KS standard.
