Within the context of urban planning in the 21st century, it is important to evaluate landscape design impressions, which can be stakeholders’ important criteria for selecting urban green space proposals in public offering processes. In this study, we aimed to establish a questionnaire for rating impressions of urban green spaces in public offering processes. First, we conducted a qualitative pilot survey collecting 127 items for expressing impressions of urban green spaces selected from recent cases of public offerings in Tokyo. Then, based on the results of two online questionnaires (N = 300 and 100, respectively) and exploratory factor analyses, we identified 22 items classified into 3 factors, such as beautiful sight, unsatisfactory maintenance, and accessibility. General structure of these 3 factors was reproduced by a confirmatory factor analysis, indicating that factors found in this study can be useful for rating impressions of urban green spaces in public offering processes.

We evaluated the suppressing effect of weak-acidic polyester on itching during sleep when wearing a sleep garment made of weak-acidic polyester for the patients with atopic dermatitis. The weak-acidic polyester knitted fabric was prepared from commercial weak-acidic polyester, and applied for a sleep garment. The degree of itching during sleep was evaluated by VAS, and it was confirmed that the degree of itching was lower in patients with atopic dermatitis when wearing a sleep garment made of weak- acidic polyester than when wearing that made of untreated polyester. When the patients with atopic dermatitis work up a sweat during sleep, the sweat contains histamine as an itching component so that they feel itchy while sleeping. The weak-acidic polyester has an antibacterial effect against Staphylococcus aureus by maintaining the skin pH around 5.5, and it is considered that itching could be inhibited by suppressing the growth of Staphylococcus aureus.
