  • The theory of household arts and practical acts are two traditional mainstream topics of official South Korean secondary home economics education. The clothing and textile education within the Secondary School Home Economics Textbook (1948) is various and practical. The first year textbook discusses the symbolism and maintenance of uniforms that provides information on the characteristics of cotton. Clothing and textiles are covered in 26 pages out of the 76 page book. The second year textbook includes the theory of color and form, along with the characteristics of flax and silk. Clothing and textile education is covered in 33 pages out of the 97 second year textbook. The third year textbook deals with the characteristics of wool, manufactured fibers, cross weaving, removing stains, clothing arrangements, and equipment; 5 chapters (56 pages out of 137) are spent on clothing and textiles. The fourth year textbook introduces the history of clothing, laundry principles, dyeing, bedclothes, and bed accessories; 4 chapters (63 pages out of 125 pages) are spent on clothing and textiles. The Secondary School Home Economics Textbook (1948) is highly extensive and profound in depth. It is comparable with modern college or specialized high school level clothing and textile education in terms of clothing materials, clothing maintenance, color theories, and dyeing.

  • Since the ancient times, black has been the most valuable color. Also, it has played a more important role in a history of fashion than other colors. In general, black was regarded as a color of negative images. However, as people have recognized the aesthetic value of black color, they have expressed unique and various images of black through the medium of clothes. This studies on images of black dress for woman was based on reference to literatures and valid investigations. The images toward black clothing are categorized by study participants' perceptions according to age, marital status and education. The result was as followed. Dignity and modernity were the most frequently cited image of black dress among women followed by feminine, sorrow, sensuality, and abstinence. Age significantly affected the recognition of black dress images. Woman showed significant difference in recognizing dignity, modernity, sensuality, and sorrow in black dress according to their age. Woman more strongly recognize dignity and modernity in black dress when they are younger, while increasingly recognizing abstinence and sensuality in black dress as they become older. Marital status significantly affected woman's recognition of black dress. They showed meaningful difference in recognizing dignity, modernity, and abstinence in black color. In sum, single women recognized more easily dignity and modernity in black dress and less easily abstinence than married women. Women also showed the trend with relation to education level. In general, as women got higher education, they also increasingly recognized dignity and modernity in black dress.

  • The mechanical characteristics (texture and color) and consumer preference of Doraji Yanggengs using different pre-treatments and added levels of Doraji were presently evaluated. Three kinds of Doraji Yanggengs were made with differing amounts of Doraji powder (DPY; 30, 50, or 70 g), ground raw Doraji (GRDY; 100, 200, or 300 g), and Doraji juice (DJY; 100, 200, or 300 g). Texture characteristics (hardness, adhesiveness, springiness, chewiness, gumminess, cohesiveness) and color values (lightness, redness, yellowness) were measured three times in three experiments conducted with each formulation. Preference was measured with a nine-point hedonic scale for Yanggengs once every three experiments. Consumer preference was measured with color, flavor, taste, appearance, texture, and overall acceptability. Significant differences according to the amount of Doraji powder were evident with DPY for hardness (p<0.001), adhesiveness (p<0.05), and cohesiveness (p<0.001). Hardness (p<0.001), adhesiveness (p<0.001), chewiness (p<0.01), and gumminess (p<0.01) of 100 g GRDY displayed higher scores than 200 g and 300 g GRDY, but displayed significantly lower scores in cohesiveness (p<0.01). Hardness (p<0.001), adhesiveness (p<0.001), chewiness (p<0.001), gumminess (p<0.01), and cohesiveness (p<0.05) of DJY showed significant differences according to amount of Doraji juice. The highest score in a preference test among DPYs was evident for 30 g DPY. There were no significant differences in preference among GRDYs and DJYs. Color, flavor, taste, appearance, texture, and overall acceptability were significantly (p<0.01) correlated in all Yanggengs. DJY was preferred more than DPY and GRDY. Women in their forties and fifties preferred Yanggeng more when compared to women in their twenties and thirties.

  • Natural dyes are environmentally and human compatible. But they are not various or not fast in color. The mixed dyeing have been attempted to solve these disadventages of natural dyes. The persimmon juice dyed fabrics have brown-color and good hygienic properities however low color fastness. The onion dyeing show similar brown-color and have good color fastness caused by querectin existed in onion outer skins. Mixed dyeing was carryied out on silk fabrics using persimmion juice and onion outer skin extract in this study. The mixing method were persimmon juice dyeing and then onion dyeing(P-O), onion dyeing and then persimmon juice dyeing(O-P) and dyeing in the mixture of persimmon juice and onion outer skin extract simultaneously(P+O). The mordants were none-mordent, gallic acid after-treatment and alum after-treatment. Several persimmon juice dyed fabrics were irradiated for 2 hours before onion dyeing(PU-O). The color values of dyed silk fabrics were as follows. The persimmon juice dyed silk fabric developed to yellow-red color after 2 hours of uv irradiation. Onion dyed fabrics show similar yellow-red color after dyeing without uv irradiation. The effect of alum after-treatment on color difference were highest in onion dyeing. The dyeabilities of both P-O and O-P were higher than persimmom juice dyeing and onion dyeing. The dyeabilities of P+O was lower than persimmom juice dyeing and onion dyeing. The value of color difference of alum-treated fabric was the highest. The color difference of P-O and O-P caused from 2 to 4 hours of uv-irradiation were lower than those of persimmon juice dyed fabrics. Onion skin extract could prevent the color-change of persimmon juice dyed fabrics in mixed dyeing. The color difference of PU-O was higher than the P-O.

  • Many cities in developed countries are showing their unique urban image reflecting their own culture, history, and aesthetic tastes. Especially color, one of the major design elements, has greater impact than other visual factors to form an unique urban characteristic. Despite the long history and cultural background, Seoul as a capital city of Korea does not have been successful to show an unique city image with the perspective of color. As a leading city of design, Seoul is trying to make its own urban identity through the symbolic environmental color, 'Seoul Color'. The purpose of this study is to identify the perception on the Seoul Color established by Seoul City among design practitioners and to suggest strategies for implementing the 'Seoul Color' in various fields of environmental design to set up un unique urban image of Seoul City. For this purpose, questionnaire survey was used and 77 questionnaires were analysed. Although most of the respondents did not know the 'Seoul Color', they recognized the importance of it as a major tool of building an unique urban identity of Seoul City. Respondents recognized the representing color image of Seoul as gray. Therefore, it shows a need for environmental policy to make an eco-friendly and lively city image of Seoul instead of current monotonous image. Also in order to make a unique urban image of Seoul city, 'Seoul Color' should be applied to the shape of landscape of Seoul differently. In addition, many strategies including advertisement, education, making up obvious goals for using the 'Seoul Color', and so on were suggested as conclusion.
