This study investigates music learning video content at e-Hakseupteo, a government-supported e-learning platform utilized during the COVID-19 pandemic, and provides suggestions for remote music learning in the future. The data from music learning videos in e-Hakseupteo were extracted via each subject to statistically analyze the data in various aspects including provision regions, the content providers, target audiences, video titles, and contents of each music learning video. As a result, this analysis demonstrated that e-Hakseupteo offered students fewer opportunities to learn music than other subjects because of the significant lack of music learning videos. In addition, e-Hakseupteo has provided unequal music educational opportunities and regional discrepancy due to the unintentional access settings. Finally, the music learning videos at e-Hakseupteo were produced by specific agent groups in Seoul with limited experts. Implications and suggestions are provided for the sustainability of remote learning in music education.

Background This study aimed to investigate the prevalence rate of hepatitis C virus (HCV) infection and identify the demographic, and sociological characteristics and changes in awareness of HCV infection by participating the study for North Korean defectors residing in South Korea. Methods This study prospectively enrolled participants. Demographic, sociological and clinical data, and questionnaire surveys focused on awareness of HCV infection were collected. Results In total, 211 North Korean defectors participated in this study from September 2020 until June 2021. There were 174 women (82.5%), and the overall mean age was 48.9 years (range, 20 to 80 years). Of these participants, 112 (53.1%) had immigrated to South Korea since 2011. The overall prevalence of anti-HCV antibody among North Korean defectors was 1.9%. Thirty participants (14.2%) had hepatitis B surface antigens. A huge lack of awareness regarding HCV infection has been observed among North Korean defectors. Conclusion This is the first prospective study to investigate the prevalence rate of HCV infection among North Korean defectors residing in South Korea. As North Korean defectors are a vulnerable group concerning HCV infection, they may benefit from HCV screening policies and educational interventions for HCV infection.
