Affective boundaries
In 2024, the Seoul Metropolitan Government launched the Foreign Housekeeping Managers Pilot Project, employing Filipino domestic workers to address care labour shortages amid low fertility and aging. As Korea's first formal institutionalisation of migrant care work, it offers a rare chance to observe how public commenters on Naver, the country's dominant news portal, interpret and contest this change. Using a mixed-methods computational approach …
The role of three-dimensional knowledge target teaching combined with immersive clinical experience in otology teaching practice
OBJECTIVE: This study aimed to evaluate the impact of three-dimensional knowledge-targeted teaching combined with immersive clinical experiences on otology education. METHODS: A prospective study was conducted on 100 undergraduate interns in their eighth semester of otolaryngology training at Anhui Medical University from June 2023 to November 2024. They were randomly assigned to either a control group (n = 50), which received conventional teachi…
Predicting and explaining recurrent child abuse using interpretable machine learning
From Bureaucracy to Startups
a widely used anonymous platform for Korean employees. Using topic modeling techniques, we examine bullying-related discourse across four organizational types: public institutions, large companies, midsize companies, and small firms/startups. Our findings indicate that workplace bullying manifests differently across organizational types. In public institutions, it is characterized by hierarchical pressure and institutional rigidity; in large comp…
Examining the Changes in Bullying Discourse on Reddit
Bullying, a type of power abuse, deserves to be addressed, and this study examines bullying-related discussions on Reddit before and after the pandemic to better understand its dynamics during this time. We analyzed 8,720 posts and 21,607 comments from the r/Bullying subreddit using static and dynamic topic modeling (DTM) to understand the major topics discussed in the subreddit. Based on static topic modeling, we discovered that before the COVID…
Comparing social media engagement between women with suicidal ideation and those who have attempted suicide
This study examined differences in social media engagement between women with suicidal ideation only (SI-only) and those who had attempted suicide (SA). We used content, statistical, and time series analyses on 3,510 tweets from 41 women in South Korea who had ideated and/or attempted suicide. Most tweets focused on everyday life and interests (38.0%, 1,355 tweets), while others expressed mental health distress and challenges (0.6%, 22), school o…
Understanding Double Stigma Toward Minority Groups on Social Media in the Covid-19 Pandemic
This study aims to compare social perceptions of four minority groups in South Korea categorized by religion, sexual orientation, and occupation. Using data collected from Naver News, a prominent Korean website, between February and June 2020, dynamic topic modeling was conducted on over 200,000 data points. The findings revealed that stigma-related topics such as labeling, negative stereotypes, separation, and status loss emerged in discussions …
Stalking Discourse on Reddit
Stalking, a widespread and distressing phenomenon, has recently garnered considerable attention. The advent of digital platforms has revolutionized the landscape of stalking, presenting new avenues and challenges for research. However, the impact of the coronavirus disease (COVID)-19 pandemic on stalking remains underexplored, despite extensive studies on similar crimes such as intimate partner violence and domestic violence. To address this gap,…
Linking suicide and social determinants of health in South Korea
Introduction: Studies have shown that suicide is closely related to various social factors. However, due to the restriction in the data scale, our understanding of these social factors is still limited. We propose a conceptual framework for understanding social determinants of suicide at the national level and investigate the relationships between structural determinants (i.e., gender, employment statuses, and occupation) and suicide outcomes (i.…
Analyzing China’s research collaboration with the United States in high-impact and high-technology research
This study investigates China’s international research collaboration with the United States through a bibliometric analysis of coauthorship over time using historical research publication data. We investigate from three perspectives: overall, high-impact, and high-technology research collaborations using data from Web of Science (WoS), Nature Index, and Technology Alert List maintained by the U.S. Department of State. The results show that the Un…
