Controlling fashion waste throughout the entire product lifecycle is critical in a circular economy. This study explored the possibility of establishing a public recycling system for fashion waste. Since consumer interests and participation are essential, theoretical research, social-text analysis, and quantitative research were conducted to identify consumers' perceptions of the public recycling of fashion waste and circular fashion. Data were collected via an online survey among women in their 20-30's living in Korea, and 304 samples were used for data analysis. The results were as follows. First, consumers' perceptions of recycling fashion waste were composed of recycling difficulty, the need for public recycling, and the need for EPR. Circular fashion perception comprised favor, environment protection, attractiveness, economics, quality and hygiene risks, and lack of diversity. Second, the reuse-recycle attitude and need for EPR affected the favor of all types of circular fashion products. Third, environmental concerns impacted attractiveness, and the favor significantly affected the purchase intention of all types of circular fashion products. In particular, quality and hygiene risk negatively affected the purchase intention of used-fashion products, while attractiveness positively impacted the purchase intention of upcycled-fashion products. The results implied that discussing the public recycling system of fashion waste and EPR policy is imperative. The results also showed the need to classify different types of circular fashion products, such as used, upcycled, and regenerated fashion items, to examine consumers' perceptions. In addition, the recycling of the fashion waste scale developed in this study could be used for further research.

Assistive technologies are necessary for ensuring independent living and equal participation in an information-based society for people living with disabilities (PLWD). This study investigated the assistive technology preference of students with visual disabilities, and the approach academic libraries should adopt in procuring assistive technologies. The study adopted a quantitative research method, with a survey as the research design. The study was conducted among visually disabled students in four public universities in Nigeria. Using the total enumeration method, an online questionnaire was used to obtain information from 151 students who voluntarily agreed to partake in the survey. The study found that access to electronic resources, scanning/conversion of print resources to electronic formats and access to information on the Web were among the technology-based services provided to visually disabled students. COBRA, ZoomText, Supernova and Dragon Naturally Speaking are the most preferred assistive technologies (software). At the same time, handheld scanners ($\bar{x}=4.40$) and braille keyboards ($\bar{x}=4.60$) are the most preferred assistive technologies in the hardware category by visually challenged students. The study further revealed that the library management should consult with students living with a visual disability before procuring assistive technology. Findings from this study thus provide further evidence of the need for librarians to fulfil their moral and legal obligation in advocating the provision of assistive technologies. Library administrators and university stakeholders should expedite actions on meeting the assistive technology needs of people living with visual disabilities. These actions should transcend mere policy formulation on the provision of assistive technologies to restructuring their services and spaces to accommodate assistive technologies as information service delivery tools for people with visual disabilities.
