Background: The prevalence of service-oriented roles in the contemporary workplace has led to an increased demand foremployees to engage in emotional labor to navigate the challenges of a service-oriented economy. This study aimed to examine the association between emotional labor and work absence due to dental treatment and assess the role of various factors between emotional labor and work absence due to dental treatment. Methods: Four hundred and eighty-three workers participated in this survey. Work absence was an outcome variable, andemotional labor was an independent variable. Logistic regression analyses were performed to find the association between emotional labor and work absence due to dental treatment controlling for age, sex, and education. The impacts of mediators (work type, employment type, and stress) were also assessed. Furthermore, the association between emotional labor and absenteeism due to dental treatment was assessed according to the stress level. Results: Emotional labor was associated with a 1.75 times higher risk of absenteeism due to dental treatment (95% confidenceinterval 1.04∼2.83) across adjusted models among Korean workers. The impact of stress was the highest among the mediators.Despite the non-statistical significance of the results, it was observed that elevated stress levels were correlated with increased dental absenteeism due to emotional labor. Conclusion The findings of this study indicate that the performance of emotional labor is associated with an increased prevalenceof absenteeism due to dental treatment. High stress levels may result in even higher rates of absenteeism among Korean workers.

In the 2023 series, we summarized the major clinical research advances in gynecologic oncology based on communications at the conference of Asian Society of Gynecologic Oncology Review Course. The review consisted of 1) Endometrial cancer: immune checkpoint inhibitor, antibody drug conjugates (ADCs), selective inhibitor of nuclear export, CDK4/6 inhibitors WEE1 inhibitor, poly (ADP-ribose) polymerase (PARP) inhibitors. 2) Cervical cancer: surgery in low-risk early-stage cervical cancer, therapy for locally advanced stage and advanced, metastatic, or recurrent setting; and 3) Ovarian cancer: immunotherapy, triplet therapies using immune checkpoint inhibitors along with antiangiogenic agents and PARP inhibitors, and ADCs. In 2023, the field of endometrial cancer treatment witnessed a landmark year, marked by several practice-changing outcomes with immune checkpoint inhibitors and the reliable efficacy of PARP inhibitors and ADCs.

This manuscript represents the official position of the Korean Society of Echocardiography on valvular heart diseases.This position paper focuses on the clinical management of valvular heart diseases with reference to the guidelines recently published by the American College of Cardiology/American Heart Association and the European Society of Cardiology. The committee tried to reflect the recently published results on the topic of valvular heart diseases and Korean data by a systematic literature search based on validity and relevance. In part I of this article, we will review and discuss the current position of aortic valve disease in Korea.
