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 mushrooms have been used as traditional medicines and food resources in many countries. The objective of this study was to determine antioxidant compounds and to evoluate tyrosinase inhibitory activity of extracts from Hypsizigus marmoreus. The pileus and stipe of Hypsizigus marmoreus were extracted with methanol and water, separately. The methanol extract of Hypsizigus marmoreus were fractioned by hexane, chloroform, ethylacetate and buthanol. The concentrations of total polyphenolics and flavonoids in methanol extracts were investigated by colorimetric methods. The concentrations of total polyphenolics and flavonoids in methanol extract of the pileus was higher than methanol extract of the stipe. The DPPH redical scavenging activity of the pileus extract was also higher than stipe extract in methanol extract. The IC50 of DPPH redical scavenging activity of the pileus and stipe in methanol extract were 18 mg/ml and 1 10 mg/ml, respectively. The IC50 of tyrosinase inhibitory activity of the pileus and stipe in methanol extract were 500 mg/ml and 1,000 mg/ml in methanol extract. These results suggest that Hypsizigus marmoreus can be potentially used as a source of natural antioxidant agent in the cosmetic industry as well as the food, pharmaceutical and medicinal industry.
