Validation of the Korean Version of the Pain-related Beliefs and Attitudes about Sleep (PBAS) scale Among Patients with Chronic Pain.

Objectives: We assessed the reliability and validity of the Korean version of the Pain-related Beliefs and Attitudes about Sleep (PBAS) scale among patients with chronic pain. Furthermore, we investigated whether pan-related dysfunctional beliefs about sleep mediate the relationship between sleep severity and pain.

Methods: Overall, 100 participants with chronic pain were recruited using an anonymous online survey.

Risk of extrahepatic malignancies in patients with autoimmune hepatitis: a nationwide cohort study.

Introduction: Nationwide, population-based data on the risk of extrahepatic malignancy in patients with autoimmune hepatitis (AIH) in Asian countries are scarce. This study aimed to examine the risk of developing extrahepatic malignancies in a nationwide cohort of patients with AIH.

Methods: Using claims data from the Korean National Health Insurance Service database, patients diagnosed with AIH between 2007 and 2019 (n=7,382) were matched in a 1:8 ratio with an age- and sex-matched control population (n=58,320).

Ionic Diode-Based Drug Delivery System.

Drug delivery systems hold promise for delivering cytotoxic drugs by controlling the timing and location of the drug release. However, conventional delivery mechanisms often fall short of achieving spatiotemporally controlled yet sustained release, which is crucial for ensuring drug efficacy and minimizing impact on surrounding tissues. Here, an ionic diode-based drug delivery system is reported that is controlled by an electric potential and capable of releasing drugs at scales ranging from nanogram to microgram.

Solution-processed nickel oxide passivation on large-area silicon electrodes for efficient photoelectrochemical water splitting.

Photoelectrochemical water splitting is a promising technology for converting solar energy into chemical energy. For this system to be practically viable, the materials and processes employed for photoelectrode fabrication should be cost-effective and scalable. Herein, we report the large-scale fabrication of nickel oxide-coated n-type silicon (n-Si) photoanodes chemical bath deposition for efficient photoelectrochemical water oxidation.

Korean adolescents' experiences studying abroad and subsequent readjustment to life after returning.

Introduction: This qualitative study explored the socio-cultural adjustment and re-adjustment experiences of South Korean adolescents who studied in English-speaking countries and later returned to South Korea.

Methods: The study interviewed 12 adolescents (6 males, 6 females) aged 12-16 who studied in countries such as the U.S.
