This study applies the Information Adoption Model (IAM) to examine how users adopt health information when searching for health-related content on YouTube. Reflecting the characteristics of the YouTube platform, this study analyzes the effects of health information quality (relevance, timeliness, and conciseness) and the credibility of YouTubers as information providers (expertise, reputation, and trustworthiness) on health information adoption, with perceived usefulness serving as a mediator. An online survey was conducted among users who had experience watching health-related videos on YouTube, yielding 212 responses, of which 189 valid responses were used for the final analysis. Data were analyzed using SPSS 27.0 and SmartPLS 4.1, with PLS-SEM employed as the main analytical method. The results show that all subdimensions of health information quality—relevance, timeliness, and conciseness—have significant positive effects on perceived usefulness. Among the credibility factors of YouTubers, trustworthiness has a positive effect on perceived usefulness, whereas expertise and reputation have no significant effects. In addition, perceived usefulness has a strong positive effect on health information adoption. This study contributes theoretically by empirically identifying the cognitive mechanisms underlying health information adoption in the YouTube context and provides practical implications for enhancing the quality and credibility of health-related content.

This study analyzed the effects of early adaptation capacity on post-graduation career outcomes, mediated by academic achievement (GPA), among 51 Library and Information Science graduates from a junior college based on data collected across three time points. The findings are as follows. First, among the adaptation capacity variables, family conflict was the factor most strongly associated with direct differences in career outcomes across groups, suggesting that the home environment during college has a lasting influence on post-graduation career transition. Second, self-control increased the likelihood of employment by approximately 4.6 times, indicating that self-regulatory ability is closely associated with career preparation in the library and information science field. Third, future adaptability, goal orientation, and self-esteem indirectly affected post-graduation career outcomes through academic achievement, empirically confirming a pathway through which positive future expectations, academic motivation, and psychological resources contribute to post-graduation career outcomes through academic achievement. These findings suggest that student support should extend beyond academic achievement to include psychological and emotional interventions, such as strengthening self-control and assessing home environmental risks. Regular counseling and support programs for students from vulnerable backgrounds may improve both academic persistence and adaptability during career transitions. In addition, practical career education reflecting employment conditions in the library and information services field, combined with self-regulation training, may further enhance graduates’ career adaptability.

This study analyzes specialized public libraries in Korea from the perspective of local revitalization and proposes their typology and operational models. The cases were classified into five types: theme-based, user group-based, function-based, local resource-based, and hybrid specialization. The findings show that specialized public libraries function not merely as libraries with distinctive collections or programs, but as public platforms that connect local memory, culture, everyday issues, local industries, and community networks. Based on the analysis, this study proposes six operational models: the local resource archive model, the cultural creation and experience model, the everyday problem-solving model, the local industry and entrepreneurship support model, the social inclusion and life-cycle support model, and the local collaboration platform model. The study redefines specialized public libraries as strategic public infrastructure for local revitalization.
