PURPOSE: The purpose of this study was to investigate the effects of a simulation-based practice program on nursing students' self-efficacy, critical thinking disposition and problem solving process.METHOD: A quasi-experimental non-equivalent control group pre-post test, design was used. A total of 111 students, 53 students for the experimental group and 58 students for the control group. The experimental group participated in the program for 30 hours during 4 days. Data were analyzed using descriptive statistics, X2-test, Fisher's exact probability test, and t-test.RESULTS: The results showed that the simulation-based practice program significantly improved self - efficacy and critical thinking disposition of nursing students. However, there was no significant difference in the problem solving process.CONCLUSION: Therefore, to promote self-efficacy and critical thinking disposition in nursing students, it is necessary to actively use simulation-based practice program. To improve the problem solving process in the future, it is necessary to apply the simulation-based practice program to the nursing curriculum continuously and to use it considering sufficient education periods.

PURPOSE: We created an 'AAPM TG18 Evaluation Tool' and we determined its usefulness for the quality control of a diagnostic monitor. MATERIALS AND METHODS: We created an evaluation tool (the AAPM TG18) for conducting quality control of a diagnostic monitor, and we evaluated the measurement items of the AAPM TG18 evaluation tool. The measurement items were geometric distortion, fixed quantity assessment and visual assessment of the veiling glare, and we carried out adjustment for the luminance meter 0% calibration, which was used to revise the diagnostic monitor DICOM LUT. RESULTS: With the AAPM TG18 Evaluation Tool, we measured the 2-dimensional length when evaluating the quantitative geometric distortions in the TG18-QC test pattern, and we measured the veiling-glare ring response function, which provided information regarding the spatial extent of the luminance spread, and this measurement of the can be performed using the TG18-GV pattern. Additionally, the AAPM TG18 Evaluation Tool can be used for sensor calibration to standardize the basic rate of 0% luminance when performing periodic calibration. CONCLUSION: The evaluation tool is a very useful for easily evaluating many of the examination items of the AAPM TG18 for performing quality control of a diagnostic monitor.

PURPOSE: To report the short-term results of second-generation metal-on-metal total hip arthroplasty (THA). MATERIALS AND METHODS: One hundred and sixty-five patients (169 hips) were followed for more than 2 years after primary THA using a modern metal-on-metal bearing conducted between April 2000 and March 2002. All patients were examined clinically and radiographically. RESULTS: The average Harris hip score improved from 53.9 points preoperatively to 94.2 points at the time of the last follow-up. All prostheses demonstrated radiographic evidence of bone ingrowth. Nine patients (10 hips) had an osteolytic lesion localized at the greater trochanter. Patients with osteolysis had a significantly higher rate of positive skin-patch tests for cobalt than controls (p=0.031). Of these, two hips underwent revision operation due to recurrent dislocation and imminent fracture through the greater trochanter, respectively. There was no evidence of metal wear on the retrieved bearing surfaces, but microscopic analysis of periprosthetic tissues revealed abnormal histological findings consistent with delayed-type hypersensitivity. CONCLUSION: Early results of THA using the current metal-on-metal bearing design were encouraging in most of the patients. However, this implant bearing should be avoided in patients with a history of allergic reaction to metals.

Objective: The purpose of this study is to identify the types of pain changes that affect older Koreans, as well as their effects on depressive symptom. Methods: We analyzed the Korean Longitudinal Study of Aging data collected from 2010 to 2018. A data of total of 1,359 participants, aged 65 or older were used to estimate the change in pain. A latent growth model and growth mixture modeling were performed to estimate the overall change in pain and to categorize the types of pain changes. Results: The pain changes of older adults were classified into two categories: low-stable and high increasing. The depressive symptom showed a stronger relationship among the high-increasing type of pain than the low-stable type. The high-increasing type had a higher percentage of females, lower income, relatively low educational attainment, and a higher percentage of rural residents than the low-stable type. Conclusion The significance of this study is that it reiterated the importance of early pain diagnosis and intervention by identifying the types of pain changes in older adults and analyzing their effects on depressive symptoms. Therefore, it is especially important to pay attention to interventions that are designed to help vulnerable groups with a high risk of pain obtain effective pain management.

PURPOSE: This study aimed was done to analyze recent trends in nursing research published in the Journal of Korean Academy of Nursing by focusing on the content of nursing interventions and their level of evidence. METHODS: A total of 209 studies published between 2007 and 2008 were reviewed using analysis criteria developed by the researchers. RESULTS: The number of quantitative studies was greater than that of qualitative studies. There was a slight increase in the number of qualitative studies and studies including elderly populations, which reflects the recent population trend in Korea. More randomized controlled trials with a low risk of bias were needed to support more evidence-based nursing practice. Concerning the low rate of ethical consideration, stricter application of research ethics needs to be encouraged. CONCLUSION: The findings of this study suggest the recent trends in nursing research and the direction of nursing research and review in the Journal.

Endoscopic retrograde cholangiopancreatography (ERCP) fails occasionally due to a surgically altered anatomy, periampullary diverticulum, difficult cannulation, or poor general condition of the patient. In these cases, alternative treatment options are necessary, including percutaneous transhepatic biliary drainage (PTBD) or percutaneous transhepatic gallbladder biliary drainage (PTGBD). Here, we report a case of cholangitis treated with percutaneous transhepatic gallbladder papillary balloon dilatation (PTGBPBD). A 61-year-old male was admitted for cholangitis associated with biliary sludge. ERCP cannulation had failed due to the position of the papilla within a large periampullary diverticulum, and PTBD had failed due to a non-dilated intrahepatic bile duct. Following PTGBD, papillary balloon dilatation was completed successfully through the PTGBD tract. The patient tolerated the procedure and was discharged without complications. We conclude that PTGBPBD is an acceptable and safe procedure in a patient with cholangitis who underwent failed ERCP or PTBD procedures.
