RESUMEN
This study examines the usability of communication-assistive applications for hearing-impaired users, with a focus on enhancing user experience and promoting social inclusion. Although such applications have been developed and evaluated previously, interface designs that consider the intimacy needs of hearing-impaired users remain under-explored. We performed a comprehensive usability evaluation employing a mixed-method approach, which involved hearing-impaired individuals as well as field experts. The findings revealed areas for improvement in the design, validated the feasibility of implementing these applications, and emphasized the importance of incorporating the unique needs and preferences of hearing-impaired users. Furthermore, this paper discusses the importance of introducing guidelines and evaluation scales for the "Design for Emotion and Life Knowledge" levels to facilitate smooth and effective human-computer interactions. Such measures will promote the development of intelligent assistive technologies that reflect the qualitative needs of people with disabilities and contribute to social rights for hearing-impaired users. With the growing demands of artificial-intelligence-powered assistive technologies, the inclusion of individuals with disabilities in the design and research process is anticipated to increase. In future, studies should be conducted to blend the culturally shared experiences and emotional bonds expressed by users (having mild-to-severe hearing impairment) with the design and development process of assistive devices or services.

Escherichia coli has commonly been associated with diarrheal illness in humans and animals. Recently, E. albertii has been reported to be a potential pathogen of humans and animals and to be carried by wild birds. In the present study, the prevalence and genetic characteristics of intimin-producing E. coli and E. albertii strains were evaluated in wild birds in Korea. Thirty one of 790 Enterobacteriaceae strains from healthy wild birds were positive for the intimin gene (eaeA) and twenty two of the 31 strains were identified as atypical enteropathogenic E. coli (aEPEC) that did not possess both EAF and bfpA genes. A total of nine lactose non-fermenting coliform bacterial strains were identified as E. albertii by PCR and sequence analysis of housekeeping genes. A total of 28 (90.3%) eaeA-positive strains were isolated from waterfowl. Fifteen aEPEC (68.2%) and two E. albertii (22.2%) strains had a ß-intimin subtype and 14 aEPEC strains harboring ß-intimin belonged to phylogenetic group B2. AU eaeA-positive E. albertii and 3 aEPEC strains possessed the cytolethal distending toxin gene (cdtB). The eaeA-positive E. coli and E. albertii strains isolated from healthy wild birds need to be recognized as a potential pathogroup that may pose a potential threat to human and animal health. These findings indicate that eaeA-positive E. coli as well as E. albertii can be carried by wild birds, posing a potential threat to human and animal health.
