Global fashion houses have recently incorporated traditional Korean motifs within their inspiration. This trend is an opportunity to showcase the colors of traditional Korean culture by investing in the new design content. Products specifically based on traditional Korean culture are lacking in brand awareness despite the success of Korean content. Accordingly, this study designs cultural products based on Korean folk painting that captures Korean people’s satirical sense of humor. Korean folk painting theories are analyzed, from which different types of folk paintings are classified based on research of bibliographies and online documents. Following classification, the results are dataized as different types of folk paintings and their meanings. Furthermore, images of folk paintings are categorized and scanned digitally. The digitized images of the folk paintings are processed through Adobe Photoshop CS for overall layout and Adobe Illustrator CS for detailed designs. Traditional categories of Korean folk paintings are used, including flowers and birds, letters, and study stationery. Using the main elements of the flower and birds category, designs with cultural products such as images of flowers, birds, animals, and fish are produced. The final designs are used to create fashion items that can easily be used for embellishment or self-presentation: a scarf and a necktie. The scarf and the necktie are not only merchandise; they also symbolize the story, humor, and hope that Korean folk paintings once symbolized.

The purpose of this research was to revive the bathochromic effects of wool fabrics by using natural dyestuffs with minimum heavy metallic mordants. The natural dyestuffs used in this research were the indigo plant, Phellodendron amurense, and Caesalpinia sappan. Sample no. 1 was pre-dyed five times with indigo. Sample no. 2 was pre-dyed five times with indigo and then once dyed with Phellodendron amurense. Following the same method as sample no. 2 with an additional Phellodendron, Sample no. 3 consisted of a pre-dye five times with indigo and twice with Phellodendron amurense. Sample no. 4 was pre-dyed six times with indigo and then once dyed with Caesalpinia sappan. Sample no. 5 followed the same method as no. 4 with an additional dye of Caesalpinia sappan. Sample no. 6 was pre-dyed five times with indigo and then once dyed with Phellodendron amurense and once dyed with Caesalpinia sappan. The results were as follows: first, all samples showed deeper colors. Second, according to the results of the surface K/S measurement, the surface K/S of wool fabrics was >20. Third, the results of lightfastness measurement showed superiority over grade 4 in samples no. 1, 2, 3, 5, and 6. However, sample no. 4 was grade 3. In the colorfastness to washing measurement, sample no. 2 showed greater superiority than grade 3—4, while samples no. 1 and 3 were grade 3. In addition, the colorfastness to dry cleaning for all samples was satisfactory or excellent by more than grade 3.

The purpose of this study is to offer basic data on cosmetics by investigating college women’s purchasing and use behaviors regarding cosmetics according to their experience with side effects. A questionnaire was administered to 351 college women in the Seoul and Kyoung-in areas. The data were analyzed with SPSS Statistics V22.0 using frequency, χ2-test, and t-test. The results are as follows. First, 72.6% of surveyed women reported experiencing side effects from cosmetics. The largest side effects were acne and boils, and the primary ways of coping with these side effects were discontinuing use and using other products. Second, the group that experienced cosmetics’ side effects used brands that were more expensive and eco-friendly than the group without side effects. Third, the group that experienced side effects continued to use the product more than the group without side effects. The primary reason for continued use was efficacy, and the reasons for discontinued use were efficacy and curiosity. Fourth, the side-effects group proactively identified cosmetics ingredients more than the non-side-effects group. Specifically, they checked the major components, the function, and for any hazardous ingredients. Fifth and finally, 98.3% of survey respondents purchased and used functional cosmetics. The group that had experience with side effects used more functional cosmetics than the group without side effects.

The purpose of this study was to examine visually impaired people's clothing behavior, using a qualitative approach. The results are intended to be used as baseline data to make an instrument that can measure the factors that have an effect on visually impaired people's clothing needs from the perspective of environmental and social relationship contexts. This study was made through in-depth interviews with people with grade-1 visual impairment, and the results were as follows: First, when purchasing clothing, they were accompanied by trusted people, and chose trusted brands and trusted products. They spent as little time as possible, did not try on many clothes, and they preferred colors, designs, and purchase methods that carried as low a risk as possible. Second, they wanted basic product information and simple procedures when purchasing and using clothing products. Third, they were able to manage their own clothes themselves. However, there was insufficient laundry information available. Fourth, the main reason why visually impaired people took care of their appearance was that they wanted to look neat and clean to be respected by others. Based on the study results, it is necessary to provide information on clothing to improve quality of life and welfare and thus ensure visually impaired people’s independence.

The purpose of this research is to revive the colors of combination dyeing and mixed dyeing with natural dyestuffs. The fabrics used were cotton and rayon. The natural dyestuffs used in this research were indigo, Phellodendron amurense, and Caesalpinia sappan. The effects of combination dyeing were as follows. First, all samples showed deeper colors. Second, according to the results of the surface K/S measurement, while the surface K/S of cotton was over 15, that of rayon was over 17. Third, the results of the light fastness measurement showed the superiority (by over grade 4) of all the samples, except in the case of rayon fiber sample no. 6 (which had been pre-dyed with indigo five times before being dyed with P. amurense once and then being dyed with C. sappan once). In the color fastness to washing measurement, all fibers showed superiority (by over grade 3~4). In addition, the color fastness to dry cleaning of all fibers was satisfactory or excellent (by over grade 3). Fourth, according to the results of the tensile strength measurement, it tended to decrease in the case of cotton and increase in the case of rayon. Fifth, the results of the density measurement showed that the density of cotton decreased by about 15~20% in the case of warp and 10% in the case of weft for all samples. The density of rayon decreased 20% in the case of warp for all samples and increased 30% in the case of weft for all samples.

The purpose of this study was to examine laundry behavior according to the number of households and the type of washing machine that each household used. The data was obtained from questionnaires filled out by 417 households, which included college students living in Seoul and Gyeonggi province. The results of this study are as follows: first, according to the results of survey about the number of household members and type of washing machine that household had, one or two-person households accounted for 24.0%. Regarding the type of washing machine that each household used, there were more drum washers. In households comprised of three or more persons, a higher percentage had a machine with a pulsator. Second, with regard to the method of classifying the wash in doing the laundry, all families classified the wash according to color and textile material. Third, with regard to the amount of detergent in doing the laundry, 63.5% of households used the recommended amount of detergent while 28.3% of households used more detergent than the recommended amount. Fourth, with regard to the set temperature of water in doing the laundry, 36.2% of households used cold water; this was the highest percentage. Fifth, with regard to input sequence in doing the laundry, most households put the wash in the machine in advance, and then filled the washer with water; 56.1% of households added a rinsing process for all washing processes.
