Purpose: This study aimed to identify core domains for pre-registered nurses by comparing licensing competencies with program outcomes (POs) in undergraduate nursing education. This was accomplished in preparation for the transition of the Korean Nurse Licensing Examination (KNLE) from a tradition seven-subject format to a newly integrated, competency-based single-subject format that reflects current trends in nursing assessment. Methods: A literature review and survey were conducted. From 828 studies retrieved via PubMed, CINAHL, and Google Scholar using keywords such as “newly graduated registered nurses” and “competency OR competence,” 18 were selected according to pre-established inclusion and exclusion criteria. Documents from national and international nursing organizations were included to extract relevant licensing competencies. We also reviewed POs from all undergraduate nursing schools in South Korea to align educational outcomes with the identified core domains. Results: The core domains identified were clinical performance and decision-making, professional attitudes and ethics, communication and interpersonal skills, leadership and teamwork, quality improvement and safety, health promotion and prevention, and information technology and digital health. These domains showed strong alignment with POs under the fourth-cycle accreditation standards. Conclusion It concludes the seven core domains will be appropriate for evaluating pre-registered nurses in the integrated KNLE. Based on the seven identified core domains, expert consensus should be sought in the next phase to support the development of integrated, competency-based test items grounded in these domains.

Purpose: This pilot study aimed to evaluate the effects of the Floating Nurse system designed to improve nurses’ shift work conditions on individual and organizational outcomes. Methods: A non-equivalent posttest-only control group design was used. Individual-level data on job satisfaction, work-life balance, and turnover intention were collected through anonymous self-administered questionnaires from January 16 to 27, 2023, six months after system implementation. Organizational-level turnover rates were obtained from administrative records for the period before and after implementation (January-June and July-December 2022). The study included 352 nurses from 38 general wards at a tertiary hospital in Seoul-250 from 27 wards where the system was implemented (participation group) and 102 from 11 wards without the system (non-participation group).Multilevel modeling was applied, accounting for individual-level (Level 1) and ward-level (Level 2) factors. Results: Job satisfaction was significantly higher in the participation group than in the non-participation group (B=2.28, p=.008). Work-life balance was higher but not statistically significant (B=4.10, p=.120), and turnover intention showed no significant difference (B=-0.48, p=.204). Turnover rates decreased in both groups, with a larger reduction in the participation group (from 2.5% to 1.8%) than in the non-participation group (from 4.5% to 3.5%). Conclusion The Floating Nurse System improved job satisfaction and contributed to lower turnover rates, suggesting potential benefits for workforce stability. Although improvements in work-life balance and turnover intention were not statistically significant, enhanced job satisfaction may indirectly mitigate turnover intention. Further multi-site and longitudinal studies are warranted to confirm long-term effects.

Background: This study aimed to evaluate the effects of kombucha on the surface of composite resins and to examine thedegradation-inhibiting effect of adding calcium to kombucha. Methods: Six experimental groups were established, with three types of liquid kombucha: one with 3% added calcium,carbonated water as a positive control, and mineral water as a negative control. The pH and titratable acidity values of the experimental groups were measured. The samples were filled with condensed composite resin and placed in the experimental drinks for 5, 15, 30, and 60 minutes. The Vickers microhardness of the surface was measured before and after immersion, and the changes were compared. Results: The pH values of the experimental group were I’m alive (2.87±0.02), Hollys (2.95±0.01), Ediya (2.99±0.01), I’m alive +3% Ca (4.09±0.01), carbonated water (4.66±0.01), and mineral water (7.67±0.02). I’m alive (–12.35) showed the largest reduction in surface hardness, followed by Hollys (–9.78), carbonated water (–7.97), I’m alive +3% Ca (–7.82), Ediya (–7.60), and mineral water (–1.56). In the Vickers microhardness measurements, all experimental groups, except for the mineral water group, showed significant differences (p＜0.05). The scanning electron microscope results showed that the experimental group and positive control had rough surfaces and micropores. Conclusion The surface hardness was significantly reduced in all experimental groups except for water. In particular, in the caseof kombucha with low pH, the reduction rate increased, weakening the physical properties of the material. In addition, the reduction rate of surface hardness was lower in kombucha with added calcium, and it is believed that drinking kombucha containing calcium can minimize the erosion of dental materials.

Background: s/Aims: Reported incidence of extrahepatic bile duct cancer is higher in Asians than in Western populations. Korea, in particular, is one of the countries with the highest incidence rates of extrahepatic bile duct cancer in the world. Although research and innovative therapeutic modalities for extrahepatic bile duct cancer are emerging, clinical guidelines are currently unavailable in Korea. The Korean Society of Hepato-Biliary-Pancreatic Surgery in collaboration with related societies (Korean Pancreatic and Biliary Surgery Society, Korean Society of Abdominal Radiology, Korean Society of Medical Oncology, Korean Society of Radiation Oncology, Korean Society of Pathologists, and Korean Society of Nuclear Medicine) decided to establish clinical guideline for extrahepatic bile duct cancer in June 2021. Methods: Contents of the guidelines were developed through subgroup meetings for each key question and a preliminary draft was finalized through a Clinical Guidelines Committee workshop. Results: In November 2021, the finalized draft was presented for public scrutiny during a formal hearing. Conclusions The extrahepatic guideline committee believed that this guideline could be helpful in the treatment of patients.

Purpose: This study aimed to report the projected cancer incidence and mortality for the year 2024 to estimate Korea’s current cancer burden. Materials and Methods: Cancer incidence data from 1999 to 2021 were obtained from the Korea National Cancer Incidence Database, and cancer mortality data from 1993 to 2022 were acquired from Statistics Korea. Cancer incidence and mortality were projected by fitting a linear regression model to observed age-specific cancer rates against their respective years and multiplying the projected age-specific rates by the anticipated age-specific population for 2024. A joinpoint regression model was used to determine the year in which the linear trend changed significantly; we only used the data of the latest trend for prediction. Results: In total, 292,221 new cancer cases and 83,770 cancer deaths are expected to occur in Korea in 2024. The most common cancer site is expected to be the thyroid, followed by the colon and rectum, lung, breast, and stomach. These five cancers are expected to represent 55.7% of the overall burden of cancer in Korea. The most common type of cancer leading to death is expected to be lung cancer, followed by liver, colorectal, pancreatic, and stomach cancers. Conclusion The age-standardized incidence rates for female breast and prostate cancers are estimated to continue to increase. These up-to-date estimates of the cancer burden in Korea could be an important resource for planning and evaluating cancer-control programs.

Purpose: The current study provides national cancer statistics and their secular trends in Korea, including incidence, mortality, survival, and prevalence in 2021. Materials and Methods: Incidence, survival, and prevalence rates of cancer were calculated using the Korea National Cancer Incidence Database, from 1999 to 2021, with survival follow-up until December 31, 2022. Deaths from cancer were assessed using causes-of-death data obtained from Statistics Korea. Results: The number of new cancer diagnoses in 2021 increased by 27,002 cases (10.8%) compared to 2020. In 2021, newly diagnosed cancer cases and deaths from cancer were reported as 277,523 (age-standardized rate [ASR], 289.3 per 100,000) and 82,688 (ASR, 67.6 per 100,000), respectively. The overall cancer incidence rates increased by 3.3% annually from 1999 to 2012, and decreased by 5.3% from 2012 to 2015, thereafter, followed by non-significant changes. Cancer mortality rates have been decreasing since 2002, with more rapid decline in recent years (annual decrease of 2.8% from 2002 to 2013; 3.2% from 2013 to 2021). The 5-year relative survival between 2017 and 2021 was 72.1%, which contributed to prevalent cases reaching over 2.4 million in 2021. Conclusion In 2021, the number of newly diagnosed cancer patients increased as healthcare utilization recovered from the coronavirus disease 2019–related declines of 2020. Revised cancer registration guidelines expanded the registration scope, particularly for stomach and colorectal cancer. Survival rates have improved over the years, leading to a growing population of cancer survivors, necessitating a comprehensive cancer control strategy. The long-term impact of the pandemic on cancer statistics requires future investigation.

Objective: This study aimed to evaluate the diagnostic performance and procedural characteristics of fluoroscopy-guided percutaneous transthoracic pleural forceps biopsy (PTPFB) in patients with exudative pleural effusion. Materials and Methods: Patients with exudative pleural effusion who underwent PTPFB between May 1, 2014, and February 28, 2023, were included in this retrospective study. The interval between percutaneous catheter drainage (PCD) and PTPFB, number of biopsies, procedural time, and procedure-related complications were evaluated. The sensitivity, specificity, and accuracy of diagnosing malignancy were computed for pleural cytology using PCD drainage, PTPFB, and combined PTPFB and pleural cytology. Results: Seventy-one patients, comprising 50 male and 21 female (mean age, 69.5 ± 15.3 years), were included in this study.The final diagnoses were benign lesions in 48 patients (67.6%) and malignant in 23 patients (32.4%). The overall interval between PCD and biopsy was 2.4 ± 3.7 days. The interval between PCD and biopsy in the group that underwent delayed PTPFB was 5.2 ± 3.9 days. The mean number of biopsies was 4.5 ± 1.3. The mean procedural time was 4.4 ± 2.1 minutes. Minor bleeding complications were reported in one patient (1.4%). The sensitivity, specificity, and accuracy for pleural cytology, PTPFB, and combined PTPFB and pleural cytology were 47.8% (11/23), 100% (48/48), and 83.1% (59/71), respectively;65.2% (15/23), 100% (48/48), and 88.7% (63/71), respectively; and 78.3% (18/23), 100% (48/48), and 93.0% (66/71), respectively. The sensitivity and accuracy of cytology combined with PTPFB were significantly higher than those of cytological testing alone (P = 0.008 and 0.001, respectively). Conclusion Fluoroscopy-guided PTPFB is an accurate and safe diagnostic technique for patients with exudative pleural effusion, with acceptable diagnostic performance, low complication rates, and reasonable procedural times.
