Unprecedented high-temperature triggers a rapid shift in ecological characteristics of phytoplankton succession in the southern coastal waters of Korea.

Marine heatwaves (MHWs) are increasing in frequency and intensity worldwide, significantly impacting marine ecosystems. However, studies on phytoplankton community changes in coastal waters under such conditions remain. In the summer of 2024, an extreme high-temperature event (>28 °C) occurred in the southern coastal waters of Korea, providing an opportunity to investigate phytoplankton community dynamics under thermal stress.

Predictors of self-assessed likelihood of future drug use among Korean adults: the role of health beliefs and personality traits.

Substance use is a growing public health concern in South Korea. However, research on the predictive factors influencing future drug use remains limited.

Drug use is increasing in South Korea, necessitating evidence-based policy interventions. However, there is a dearth of reliable tools for identifying the personal and psychological factors that drive drug use among Korean adults. In this study, we developed and validated an instrument based on a motivational model to measure drug use motivation in the Korean context.
