Stage-specific generative AI use and dependency in learning
Generative artificial intelligence (GAI) is increasingly used in education, but its role across learning stages remains unclear. This study examined whether GAI use during learning comprehension, task-solving, or task-reviewing was associated with test performance, perceived learning, and learning satisfaction. Using a randomized between-subjects experimental design, 94 participants were recruited and 88 were included in the final analyses; prior…
Selective media exposure and political polarization in a high-choice media environment
This study investigates how homogeneous media consumption shapes political polarization by introducing a novel user-centered metric, Average Media Relatedness (AMR). Drawing on panel data from the Korea Media Panel Survey, we examine the extent to which individuals’ media repertoires exhibit internal similarity, and how this homogeneity relates to changes in political attitudes over time. Unlike traditional measures of selective exposure that rel…

The effects of regional capacity in knowledge recombination on production efficiency
Knowledge recombination, combining knowledge existing (exploitation) or new knowledge capacity (exploration) for creating knowledge collaboration, is one of the important ways of achieving innovation. However, little has known about how the knowledge recombination types affect differently to production efficiency at a regional level. This study explores the relationship between the knowledge recombination types of exploitation and exploration and…

Technology Network Structure Conditions the Economic Resilience of Regions
This article assesses the network robustness of the technological capability base of 269 European metropolitan areas against the potential elimination of some of their capabilities. By doing so, it provides systematic evidence on how network robustness conditioned the economic resilience of these regions in the context of the 2008 economic crisis. The analysis concerns calls in the relevant literature for more in-depth analysis on the link betwee…
Technological knowledge spaces and the resilience of European regions
Regional knowledge spaces are heterogeneous, and the structure of these knowledge spaces can play a significant role in shaping regional economic performances during economic downturns. This article explores the relationship between a region’s technological profile and its resilience to exogenous shocks. To identify the determinants of regional economic resilience, we perform panel analyses of EU 15 NUTS II level data covering the years before an…
Measures to Promote Rural Healthcare Tourism with a Scientific Evidence-Based Approach
The present study aimed to evaluate the effects of physical activities on human health in forests in countryside and rural areas. The test experiment was conducted in a countryside forest, whereas the controlled experiment was conducted in an urban area where the study participants resided. A total of 22 participants (aged 20.9 ± 1.3 years) were evaluated in this study. Heart rate variability and salivary cortisol level were used as indices of ph…
The effects of popularity metrics in news comments on the formation of public opinion
The influence of online comment sections on the news has increased based on the development of collective online behaviors in the digitalized news media era. In this study, we focus on the effect of comment order (e.g., sorting comments by the number of likes or by the time of posting) on the formation of public opinion. We explore whether reading comments sorted by number of likes (a) induces more comments from users, (b) increases the expressio…
Does working long hours cause marital dissolution? Evidence from the reduction in South Korea's workweek standard
Despite its important implications, little is known about the possible impact on marital dissolution of workweek standards, which set the maximum working hours for full-time workers and may, therefore, reduce their likelihood of working long hours. Moreover, evidence on the effect of working hours on marital dissolution comes predominantly from non-causal studies on Western women's work status. The Korean government reduced its workweek standard …
The Effect of Adult Children’s Working Hours on Visits to Elderly Parents
The Effect of a Reduced Statutory Workweek on Familial Long-Term Care in Korea
We interpret the findings within the context of developed Asian countries with long work hours and Confucian traditions, and suggest regulating workweeks as a policy tool to encourage familial long-term care in the rapidly aging societies
