  • This study was conducted in order to examine the egg development in red spotted grouper, Epinephelus akaara and the morphological development of its larvae and juveniles, and to obtain data for taxonomic research. This study was conducted in June 2013, and 50 male and female fish were used for the study. One hundred ${\mu}g/kg$ of LHRHa was injected into the body of the fish for inducing spawning, and the fish were kept in a small-sized fish holder ($2{\times}2{\times}2m$). Eggs were colorless transparent free pelagic eggs, 0.71-0.77 mm large (mean $0.74{\pm}0.02mm$, n=30), and had an oil globule. Hatching started within 27 h after fertilization. Pre-larvae that emerged just after hatching were 2.02-2.17 mm in total length (mean $2.10{\pm}0.11mm$), their mouth and anus were not opened yet, and the whole body was covered with a membrane fin. Post-larvae that emerged 15 days post hatching were 3.88-4.07 mm in total length (mean $3.98{\pm}0.13mm$), and had a ventral fin with two rays and a caudal fin with eight rays. Juveniles that were formed at 55 d post hatching, were 31.9-35.2 mm in total length (mean $33.6{\pm}2.33mm$), with red color deposited over the entire body, and black chromophores deposited in a spotted pattern. The number of fin rays, body color, and shape were the same as that in the adult fish.

  • The purpose of this research is to expand the realm of a button for a decorative purpose through embossing the effect and gravity of a button in fashion by designing the new ceramic buttons which are mainly used for decorative function in costume. In order to acquire a motif for the design, I analyzed several works of Gustav Klimt. As the result, those feature can be classified into the use of decorative lines, mosaic forms, and harmony of golden yellow and black, and it can be applied to buttons and clothes design. The sort of clay used in manufacturing the ceramic buttons was white clay to have high density and to diffuse light well, and press shaping techniques using plaster mold were employed. The baking was performed in an electronic kiln at $800^{\circ}C$ for the first time and at $1250^{\circ}C$ for the second time. Based on wearable designs in 2002/2003 F/W Trend of Interfashion Planning, I made three pieces of dress which could express the button's capability of decoration with effect. This is expressing a simplified form which shows up in details of and yellow and red pink were used to harmonize with golden yellow clothes. As an application of shapes of foliage in I transformed its size and form to be consistent with a jacket and a tube top. To accord with golden beige costume, I made a curve, showing up in Klimt's paintings, with golden color on a circle shape which was also a main motif in his paintings.

  • From the ancient to these days, there have been used many kinds of pigment which have two types that are inorganic pigment and organic pigment. At the ancient times, natural pigment had been used but the artificially mixed pigment has been used in modern times. By the way, searching for studies has been studied recently, it would be said the ancient pigments such as Danchung, Wall painting and Mural painting are the mainthema. However, studies about the pigments used in modern pictured relics have rarely can be found. Therefore, this analysis of Ilweolokdo would be important at the point of the pigments used in pictures of royal family in modern times and the results can be briefly summarized as below; Firstly, the results of qualitative analysis of the pigments that base or all pigments of picture was detected components of Ca, Fe and As, this results meaning that picture was used filler and basic paint. Secondly, a result of the analysis on the composition elements of the pigments shows that the main components in their composition are ;White - Lead Cyanamide($2PbCO_3$.$Pb(OH)_2$) or Titanium Oxide($TiO_2$)Blue - Ultramarine($2(Na_2O$.$Al_2O_3$ .$2Si_O2$).$Na_2S_2$)Green - Emerald green($C_2H_3A_s3Cu_2O_8$)Gold - Gold(Au), Red-Red Lead($Pb_3O_4$) or Cinnabar(HgS)Black - Carbon(C)Thirdly, X-ray diffraction analysis of crystalline structure for the blue and green pigment peeling off in picture shows that the components of blue pigment is Ultramarine($2(Na_2O$.$Al_2O_3$ .$2Si_O2$).$Na_2S_2$) and green pigment is Emerald green($C_2H_3A_s3Cu_2O_8$). Especially, microcrystalline structure of the green pigment was the shape like a cross section of wood. Consequently, we knew through the analysis of qualitative and microcrystallinestructures seen on the cross section of analyzed pigments layer that the all pigments used in the Ilweoloakdo is possible to use synthetic pigments in modern.

  • This study aims to develop contemporary fashion designs from the unique Yao minority costumes and to explore the possibility of developing creative designs by using knitting materials. The research method is based on the cultural clothing and costumes of the Chinese ethnic minority, as well as literature concerning the Yao costumes and photo data to investigate the cultural background and characteristics apparent in Yao costumes. The overall design characteristics of Yao costumes are as follows. First, the shape of Yao costumes are divided into straight-lined short tops with pleated skirts or shorts, or cardigan tops with pants and aprons, or long shirts, pants, and a belt. Each variant of tribal clothing is different. Second, the colors used are mainly black or dark blue, and these are accented by other colors, such as red, orange, yellow, green, blue, and white. Third, the clothing patterns are mainly in plant, animal, natural, geometric, and human, etc. motifs. The most common patterns in daily life are the patterns using geometric shapes, plants, or animals. Using the background of the unique lifestyles of the Yao ethnic minority, this study applied hand knitting and jacquard techniques for a knit fashion design. In order to develop traditional patterns, Yao patterns were entered into an Illustrator and SDS-ONE APEX3-4 was used for simulation. Using wool fibers as the raw material; the knitting machine used a Bird's eye Jacquard technique-10GG. The results of this research and design work were as follows. First, the knitted clothing design using Yao clothing elements has significance for the development and flexible use of ethnic elements in contemporary creative design. Second, the straight cut design using hand-knitted and jacquard-knit fabrics can minimize waste materials and provide more possibilities for sustainable design development. Third, it provides additional methods for the combination of hand-knitting and jacquard knitting fashion design.

  • Rutile single crystals grown by skull melting method were cut parallel and perpendicular to growth axis, and both sides of the cut wafers (${\phi}5.5mmx1.0mm$) were then polished to be mirror surfaces. The black wafers were changed into pale yellow color by annealing in air at 1200 and $1300^{\circ}C$ for $3{\sim}15\;and\;10{\sim}50$ hours, respectively. After annealing, structural and optical properties were examined by specific gravity (S.G), SEM-electron backscattered pattern (SEM-EBSP), X-ray diffraction (XRD), FT-IR transmittance spectra, laser Raman spectroscopy (LRS), photoluminescence (PL) and X-ray photoelectron spectroscopy (XPS). These results are analyzed increase of weight in air, decrease of weight in water and specific gravity, shown secondary phase of needle shape, diffusion of oxygen ion and increase of $Ti^{3+}$. From the above results, we suggest that the skull melting method grown rutile single crystals contain defect centers such as $O_v,\;Ti^{3+},\;O_v-Ti^{3+}$ interstitials and $F^+-H^+$.

  • Graffiti has been recognized as an art form since the influence of free, black culture and Neo-Expressionism in the 1980s, though Graffiti remains the subject of controversy both inside and outside the school Modem Art. Jean Michel Basquiat is the most famous Graffiti artist of the '80. He was regarded as the genius and star of American art, leaving a lot of experimental and creative works during his short, 9-year, creative period. In his works, Basquiat well expressed the isolated and dark shadows in the U.S., the pursuit of self identification, the purpose of expression and the epochally social phenomenon. The purpose of this study is to investigate the application of Jean Michel Basquiat's Graffiti to fashion painting. To achieve this purpose, we present a lot of fashion painting works which apply Jean Michel Basquiat's Graffiti by focusing on autographic experience, racialism, cartoon themes, monely value, and anatomical death in the characteristics of Basquiat's works. Through this process, we can express and apply Basquiat's Graffiti to fashion painting by analogizing the themes and modeling the methods of his works, such as childish and simple features, intentionally wrong spellings and sentences, and symbols of death including skeletons, intestines, bones and teeth. In addition, Basquiat's techniques are examined in this study, including the representational handling of a brush, primitive and strong colors, and maximized shape. This study found that fashion painting can juxtaposes art and fashion by expressing Jean Michel Basquiats' Graffiti.

  • As modern society advances, women's self-consciousness and attitudes toward beautiful appearances have changed. Amid this trend, the young and slim body of adolescent girls expressed in contemporary fashion incites fantasy on continuing youth among women. In modern society, women's youth is frequently regarded as a subject of consumption and a sex product in the mass media. In this regard, the study is focused on examining desire and psychology of worshipping women's youth and beauty in connection with flapper fashion in the 1920s. In the process, the study took a look at the social and cultural background of flapper fashion and conducted an analysis on formative characteristics and aesthetic sense of flapper fashion as follows: First, the formative characteristics include a short skirt that expresses straight lined shape and the beauty of exposure, lighter clothing, thick make-up, short hair style and black or vivid colors, and they lead to exceptional and innovative aesthetic sense in flapper fashion. Flapper fashion style is focused on completely denying outdated fashion worn by women in the age right before. Second, pursuit of mature, graceful and classical beauty that had continued in previous ages has gone through complete changes in the flapper era in the name of pursuit of youth, and the flapper fashion expresses sensual image through the exposure of slim arms and legs of a young girl. In the formative characteristics, aesthetic sense of youth and sensuality inherent in the flapper fashion was generated. Third, women's free-spirited lifestyle at that time and 'aesthetic sense of freedom and amusement that reflected the speed of machine civilization could be found in the flapper fashion. Material and decoration of the flapper fashion pertained to clothing that enabled a free expression through rapid movements. Aesthetic sense of the flapper fashion generated in the process could be defined as women's internal determination to express individual and free-spirited ideas through the use of fashion when tradition and order of the old age were torn down. And this aesthetic sense is continuously affecting modern fashion design.
