Purpose: This study analyzed the changes in the number of surgeries and surgical patterns due to the adoption and diffusion of new medical technology while focusing on radical prostatectomy. Materials and Methods: Medical equipment status report data and the National Health Insurance claims data from 2007 to 2019 were used. A total of 62798 radical prostatectomies from 135 medical facilities were analyzed. Radical prostatectomy was classified into open radical prostatectomy (ORP), laparoscopic radical prostatectomy (LRP), and robot-assisted laparoscopic radical prostatectomy (RARP) using the fee schedule codes. A linear mixed model was used to determine whether the adoption of a robotic surgical system had an effect on the number of surgeries and surgical patterns after adjusting for medical characteristics. Results: The number of radical prostatectomies performed in Korea increased from 1756 in 2007 to 8475 in 2019. During this period, the proportion of RARP in total surgery increased from 17.5% to 74.3%. The mean number of surgeries at medical facilities adopting the robotic surgical system was 128.3, which was higher compared to 18.5 cases in medical facilities that did not adopt it. The adoption of a robotic surgical system increased the number of radical prostatectomy surgeries by 12.1 cases and the RARP share by 47.2% in a linear mixed model.  Conclusion The adoption and diffusion of robotic surgical systems in Korea increased the number of surgeries as well as the share of robotic surgery. It is necessary to manage a technology that is widely used in a state where its clinical effectiveness is uncertain.

PURPOSE: MEN1 gene mutation causes multiple endocrine neoplasia type 1. It also suggests that somatic MEN1 gene mutation plays a role in sporadic endocrine tumor. In this study, we examined whether somatic mutations of MEN1 gene are responsible for sporadic parathyroid tumors and correlate with clinical manifestations of parathyroid tumors. METHODS: Somatic mutation of MEN1 gene in the formalin-fixed, paraffin-embedded parathyroid tumor tissue from 8 adenomas, 2 carcinomas and 1 hyperplasia were analyzed by direct sequencing. Clinicopathological parameters were reviewed from medical records and compared with the mutational data. RESULTS: Eight of eleven (73%) sporadic parathyroid tumors had somatic MEN1 mutations of 14 different types. In the 14 types, 13 were a point mutation which is composed of 8 missense mutations, 2 nonsense mutations and 3 silent mutations. One of 14 types is a frameshift deletion of 27 base pairs in exon 2. Somatic mutation was frequent in the exon 2 and exon 10. Four types of polymorphism were found. There was no correlation between the presence of mutations and clinicopathological phenotype of parathyroid tumors. CONCLUSION: This result suggests that somatic mutation of MEN1 gene plays a definite role in sporadic parathyroid tumor formation.

PURPOSE: Most students choose the same option to questions in course evaluation surveys. Identical answers to each question render the results unreliable. The purpose of this study was to analyze the trend of medical student' consistent responses to course evaluations. METHODS: The data of this study were the results of a course evaluation over 3 years (from 2006 to 2008) at the School of Medicine at A University. RESULTS: The proportion of students who replied with the same answers to each question was below 20%. This result was consistent in freshmen, sophomores, and junior students. Using a 5-point Likert scale, more than 40% of the students gave 5 points consistently. CONCLUSION: We conclude that student' responses to evaluations do not have a significant impact on the reliability of course evaluations at Medical School at A University. These results differ significantly from those of previous research. Hence, future studies are required to analyze course evaluations in medical schools using diverse aspects.

PURPOSE: Following the first in 1990, the use of course evaluations(CE) by medical schools across the Republic of Korea has grown steadily since 1997. The purpose of this study was to investigate these CE programs and to make general recommendations for further implementation. METHODS: A questionnaire survey was conducted by mail. From June 20 to September 22, 2006, data was obtained from 38 of the 41(93%) medical schools in the country. Of those who responded, 27 schools also sent their CE forms as requested. RESULTS: There was little difference among the 38 medical schools in the main body, methods, frequency, grades, systems of evaluation, and types of survey. Evaluation criteria such as instructor effectiveness, course management efficiency, and student satisfaction showed high frequency, whereas issues concerning learning objectives and workload were less common. In contrast, the stated purposes of employing CE varied from school to school. While 92% of the respondents regarded improvement to the quality of instruction as the goal of their programs, 32% indicated that CE results also factored in administrative decisions concerning promotion, tenure, and salary increases. CONCLUSION: In addition to embracing the expanding role and influence of CE in Korean medical education, schools must proactively enact measures to enhance further implementation. First, evaluation criteria should be better formulated to increase the consistency, reliability, and validity of CE results. Next, to promote efficiency, the scheduling and methodology of CE administration should carefully consider the medical curriculum. Finally, professional attitudes should be fostered to recognize the value of CE as a tool for raising educational standards overall.

PURPOSE: Although problem-based learning (PBL) has been popularized in many colleges, few studies have analyzed the relationship between individual differences and PBL. The purpose of this study was to analyze the relationship between learning style and the perception on the effects of PBL. METHODS: Grasha-Riechmann Student Learning Style Scales was used to assess the learning styles of 38 students at Ajou University School of Medicine who were enrolled in a respiratory system course in 2011. The data were analyzed by regression analysis and Spearman correlation analysis. RESULTS: By regression analysis, dependent beta=0.478) and avoidant styles (beta=-0.815) influenced the learner's satisfaction with PBL. By Spearman correlation analysis, there was significant link between independent, dependent, and avoidant styles and the perception of the effect of PBL. CONCLUSION: There are few significant relationships between learning style and the perception of the effects of PBL. We must determine how to teach students with different learning styles and the factors that influence PBL.

PURPOSE: This study examined how important graduates consider the 15 items of educational outcomes (importance) and how much they feel that they have achieved at graduation (accomplishment), determined whether outcomes varied according to profession, and assessed what graduates' educational needs are. METHODS: A questionnaire was given to 85 graduates of Ajou University School of Medicine. The data were analyzed by Kruskal-Wallis test using SPSS 12.0. The Borich formula was used to examine graduates' educational needs. RESULTS: Educational outcomes, such as medical knowledge and clinical skills at the basic medical levels, communication skills, and social accountabilities, were considered important in every profession. The Kruskal-Wallis test results demonstrated that the 15 items of educational outcomes were not significantly different between careers (p>0.05), but the average scores were. Doctors in private practice placed an emphasis on keeping a healthy body and mind and continuing lifelong learning; doctors in general hospitals emphasized understanding the health care industry's policies; and professors at university hospitals focused on proper medical ethics-the house staff emphasized teamwork with colleagues. CONCLUSION: These test results can be used as basic materials for reflecting on educational objectives, student performance, and revision of the curricula. Further studies on how to measure educational outcomes are necessary.

Purpose: The purpose of this study was to examine the differences in the medical students’ satisfaction on online flipped learning by the learning style. Methods: A total of 42 second-year medical students were participated in this study. As study tools, Felder and Soloman’s Index of Learning Styles and the Korean Educational Development Institute’s National Assessment of Student Engagement in Learning were utilized. Data analysis was conducted with the Kruskal-Wallis test, a nonparametric statistical method. Results: Results showed that there were statistically significant differences within active–reflective types and sensing–intuitive types. The active–reflective type has been shown to have statistically significant differences for the three effects of learning, such as problem solving and understanding, active participation, and self-directed learning attitudes. For sensing–intuitive type, active participation showed a significant difference from other effects of learning. Conclusion The learning style is an important concept in understanding the diverse ways in which students process and absorb new information. Hence research is needed to conduct successful small group activities through online. In the future, it is necessary to find the factors that can lead to successful online classes in medical schools.
