Efficacy and Safety of Virtual Reality-Based Versus Traditional Emotion-to-Emotion Therapy for Treatment of Hwa-Byung: A Protocol for a Single-Center, Randomized, Assessor-Blind, Parallel-Group Clinical Trial.

Background: Hwa-Byung is a culturally bound syndrome prevalent in Korea, characterized by intense emotional distress and physical symptoms related to suppressed anger. Patients frequently report experiencing chest tightness, heat sensations, and globus pharyngeus (the sensation of a lump in the throat). These physical symptoms often accompany psychological distress and can exacerbate the sense of frustration and helplessness associated with the condition.

Risk factors associated with SGLT2 inhibitor discontinuation in diabetic patients with heart failure.

Sodium-glucose cotransporter 2 inhibitors (SGLT2i), have shown benefits in patient with heart failure (HF), however, adherence remains a significant issue: with only 60% of patients continuing usage beyond a year. This study aims to identify patients at risk of discontinuing SGLT2i and promote its judicious use to reduce hospitalizations and improve cardiovascular outcomes. Using the Korean National Health Insurance Service database, patients diagnosed with HF and diabetes mellitus (n = 1,665,565) between 2013 and 2018 were identified.

A long view of social mobility in Scotland and the role of economic changes.

Changes in the social mobility of men in Scotland between the late-19th and the late-twentieth century are examined using new individual-level data from nineteenth-century censuses, linking records of men aged 0-19 in 1871 to their records in 1901, and then comparing their patterns with the social mobility of men aged 30-49 in 1974 and in 2001 as recorded in social surveys at these dates. The extent of social mobility in the nineteenth century was large. In particular, the social origins of people in the highest classes-the salariat-were very varied, indicating a society that was more open than is sometimes supposed.

Socioeconomic disparities and cardio-cerebrovascular diseases: A nationwide cross-sectional study.

Background: Venoactive drugs (VADs) based on Vitis vinifera extract are widely used in Korea. However, studies on the clinical effects and head-to-head comparisons with other groups of VADs are limited. This trial aimed to evaluate whether Vitis vinifera seed extract was noninferior to the micronized purified flavonoid fraction (MPFF) in relieving venous symptoms and improving quality of life in patients with chronic venous disease.

Vertically Phase Separated Photomultiplication Organic Photodetectors with p-n Heterojunction Type Ultrafast Dynamic Characteristics.

Photomultiplication (PM)-type organic photodetectors (OPDs), which typically form a homogeneous distribution (HD) of n-type dopants in a p-type polymer host (HD PM-type OPDs), have achieved a breakthrough in device responsivity by surpassing a theoretical limit of external quantum efficiency (EQE). However, they face limitations in higher dark current and slower dynamic characteristics compared to p-n heterojunction (p-n HJ) OPDs due to inherent long lifetime of trapped electrons. To overcome this, a new PM-type OPD is developed that demonstrates ultrafast dynamic properties through a vertical phase separation (VPS) strategy between the p-type polymer and n-type acceptor, referred to as VPS PM-type OPDs.
