  • This study was attempted to develop the physicochemical ad morphological stability test methods for the cream and lotion formulations among the cosmetic foundations and to provide the guidance for the stability methods with respect to basic emulsions and creams. With these developed stability test methods, we can evaluate the expired date or life time of the available basic cosmetics, especially basic lotions ad creams. Also, the stability test methods established in this study can be used as a guideline to test physical and morphological stability of cosmetics in the future. Thus, we selected two types of basic cosmetics such as lotions and creams made by four different cosmetic companies ad applied them to the stability test methods depending on the temperature changes such as temperature cycling and freezing-thawing cycling test. After the temperature changes, the conductivity, turbidity, particle size, creaming ratio and pH changes of the creams and lotions were evaluated and morphological changes such as crystal formation, odor, color and feeling of the creams and lotions were also tested. As the results of the stability tests, all the tested creams and lotions except for one lotion were stable. Therefore, it may be concluded that these short-term accelerated stability tests as physical stability test depending on the temperature change study were suitable for the stability testing methods for the basic cosmetics and may be useful for the establishment of the guideline for the stability test of cosmetics.

  • Quality characteristics of white bread added with lotus root powder(3, 6%) were investigated. Moisture content of white bread added with lotus root powder were higher than control. As the amount of added lotus root powder increased, the lightness, redness and yellowness of bread crust as well as the volume of the bread decreased, but the redness and yellowness of the crumb increased slightly. The content of free amino acids increased by the addition of lotus root powder and the major ones were L-glutamic acid, L-alanine, L-valine and threonine. The major flavor components were 2-methyl butanal and 3-methyl butanal, which were formed by the amino-carbonyl reaction in baking bread at high temperature. Aldehyde flavor components such as 2-ethylfuran, 2-butanedione and 3-butanedione were formed by yeast fermentation. Ethyl acetate and vinyl acetate also influenced the flavor of the bread. The addition of lotus root powder increased the hardness and fracturability, and decreased the gumminess, chewiness and cohesivenes of the bread. Sensory evaluation of white bread indicated that the addition of 3%, 6% lotus root bread enhanced the grain formation, color, mouth feeling, appearance, hardness, moistness, flavor and overall acceptability. Overall, the addition of 6% lotus root powder showed the best performance in the nutritional and functional aspects of the bread.

  • In this study, we investigated the physicochemical quality characteristics and antioxidant activities of water extracts ($20^{\circ}C$ and $95^{\circ}C$) against different parts (leaf and petiole) from Wasabia japonica (wasabi). Water extracts were divided into six types of wasabi powders: leaf hot air dried (LD), petiole hot air dried (PD), whole (leaf+petiole) hot air dried (WD), leaf steamed and hot air dried (LSD), petiole steamed and hot air dried (PSD), and whole steamed and hot air dried (WSD). Turbidity was higher in wasabi $20^{\circ}C$ water extracts than in $95^{\circ}C$ hot water extracts. Browning degree was higher in wasabi leaf extracts than in petiole extracts. The pH of hot water extraction was lower than that of room temperature extraction. Wasabi extracts did not show much difference in Hunter's color values according to extraction temperature, expected that b value of yellowness was significantly higher in leaf extracts than in petiole extracts. Carbazole pectin contents of leaf extracts were significantly higher than in petiole extracts, however water soluble pectin was higher in petiole extracts. The total polyphenol contents of LD20 and LD95 were 1,561.43 mg gallic acid equivalent (GAE)/100 g and 1,163.02 mg GAE/100 g, respectively, and total polyphenols decreased during hot water extraction. Extracts from different parts of wasabi showed a significant difference in total flavonoid contents. Total flavonoid contents of LD20, LD95, PD20, and PD95 were 554.44 mg/100 g, 396.65 mg/100 g, 55.42 mg/100 g, and 47.68 mg/100 g, respectively. In the sensory evaluation, LD95 extract showed significantly higher values than other samples in terms of color, flavor, taste, mouth feeling, and overall acceptability. In the analysis of sourness, saltiness, umami, sweetness, and bitterness taste by an electronic tongue, the sourness values of LD20 and PSD95, saltiness values of WSD20 and WSD95, and umami values of PD20 and PD95 were significantly higher than other extracts. The results of this study suggest that wasabi leaf and petiole extracts enhance qualities and antioxidant activities when used different parts together.

  • The goal of this study is to express the image of chameleons-that change their colors by light, temperature and its mood-into the sexy styles of corresponding coquettish temperamental people in Wearable Art. The method used in this study was experimenting various production mediums, including creating the textured stretch fabric, in the process of expressing the conceptual characteristics of the chameleon in Wearable Art. The concept of the work was a concoction of 'tempting', 'splendid', 'brilliant', 'fascinating', etc. that highlighted the real disposition of the chameleon. The futuristic preference of the researcher was also implicated. "Comfortable" and "enjoyable" concepts via motions were improved with the its completeness. The point of the design and production is to express symbolically the chameleon in real life, analyzing its sleek body lines, conditional colors changing, outer skins and the cubic textures. The coquettish temperamental image, the conceptual image of the chameleon, was also expressed by implication into the whole work. The entire line of this work is body-conscious silhouette. It was symbolically selected to image the outline of the chameleon that has the slim and sleek body. The exposed back is intended to express symbolically the projected back bones of the chameleon. The hood of gentle triangle line expresses the smooth-lined head part. The irregular hemlines represent the elongated chameleon's tale. The chameleon with its colors of vivid tones is characterized the colors changing by its conditions. This point was importantly treated in the working process by trying the effects that the colors are seen slightly different according to the light and angles. The material was given the effect that its surface colors are seen different in lights and angles because of the wrinkles protruded lumpy-bumpy. The various stones of red and blue tones are very similar to the skin tones of the real chameleon, and their gradation makes the effect that the colors are visibly changed with each move. The textures of the chameleon were produced via the wrinkle effect of smoke-shape, which is the result of using the elastic threads on the basic mediums stitched with 50/50 chiffon and polyester along with velvet dot patterns. The stretching fabric by the impact of the elastic threads is as much suitable for making the body-conscious line. The stones are composed of acrylic cabochon and gemstone. They are symbolically expressed the lumpy and bumpy back skin of the chameleon and produced the effect of the colors visibly different. The primary technique used in this dress is the draping utilizing the biased grains. The front body piece is connected to the hood and joined to the back piece without any seam. For the irregular hemline flares, leaving the several rectangular pieces with bias grains, they were connected by interlocking. What defines the clothes is the person in action. Therefore, what decides the completeness of clothes might be its comfortable and enjoyable feeling by living and acting people. The chameleon dress could also reach its goal of comforting and pleasing Wearable Art in the process of studying the techniques and effects that visibly differentiate the colors. It is considered as a main point of the Wearable Art, which is a comfortable enjoyable clothing tempered with the artistic beauty.
