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.

Premise: The demographic histories of temperate plants in Northeast Asia in response to Quaternary climate oscillations have long been the focus of evolutionary biologists, but have rarely been studied in herbaceous plants. Here, we investigated the phylogeographic patterns of Mukdenia and Oresitrophe.
Methods: We sequenced two plastid regions for O.

The classification of the European hornet, Vespa crabro, into subspecies based on thoracic and abdominal color patterns remains controversial. This study combined morphological assessments and mitochondrial genetic analyses to critically evaluate subspecies delimitation and introduction pathways of V. crabro, focusing on two traditionally recognized subspecies in Korea: V.

In this study, the complete genome of strain GA_C_14 was sequenced and analyzed. We isolated the strain GA_C_14 from gajami sikhae, the Korean traditional food purchased from a local market in Gangneung, Korea. The genome of the strain GA_C_14 consisted of one circular chromosome (3,196,348bp) with a guanine + cytosine (GC) content of 44.
