This study identified the acceptance of disability's impact on self-esteem among adults with disabilities in South Korea. This is a four-year follow-up study that obtained data from the Panel Survey of Employment for Persons with Disabilities from 2017 to 2020. In total, 3329 individuals participated.

Association Between Changes in Depressive Symptoms and Hazardous Drinking: Findings From the Korea Welfare Panel Study (2013-2018).

This study aimed to evaluate the longitudinal association between changes in depressive symptoms and hazardous drinking among South Korean adults. This study was conducted using a sample drawn from participants enrolled in the Korea Welfare Panel Study (KoWePS) from 2013 to 2018. Hazardous drinking was defined as a score of 11 points for men and seven points for women on the Korean version of the Alcohol Use Disorders Identification Test.

Diagnostic Concordance and Preoperative Risk Factors for Malignancy in Pancreatic Mucinous Cystic Neoplasms.

Background/aims: As pancreatic mucinous cystic neoplasms (MCNs) are considered premalignant lesions, the current guidelines recommend their surgical resection. We aimed to investigate the concordance between preoperative and postoperative diagnoses and evaluate preoperative clinical parameters that could predict the malignant potential of MCNs.

Methods: Patients who underwent surgical resection at Samsung Medical Center for pancreatic cystic lesions and whose pathology was confirmed to be MCN, between July 2000 and December 2017, were retrospectively analyzed.

Association between tinnitus and depressive symptoms in the South Korean population.

In this study, we aimed to examine the association between tinnitus and depressive symptoms in middle-aged and elderly South Korean population.
