Severe Acute Respiratory Syndrome is being impacted worldwide by the prolonged COVID-19 situation. Due to the impact of COVID-19, domestic educational institutions have also changed their teaching methods. Domestic universities traditionally aim for face-to-face lectures, but due to the pandemic, they are conducting non-face-to-face lectures. This study aims to evaluate the effect of non-face-to-face lectures on radiology students. The subjects of this study are students of the Department of Radiology at University D in Daegu. As for the contents of the study, satisfaction with non-face-to-face lecture delivery, concentration, and comprehension was evaluated. Data analysis was performed in SPSS Ver. 26 was used, and the reliability measurement was found to be Cronbach's alpha coefficient = 0.805. In the results of this study, the satisfaction of non-face-to-face lecture delivery, concentration, and comprehension was overall high. However, satisfaction with theoretical subjects (2.08±0.88) was significantly different from that of practical subjects (2.51±1.10) (t=-9.880, p<.001). Satisfaction by grade level was highest in the first grade. As a result, it is judged that non-face-to-face theoretical lectures require more careful preparation from lecture planning than practical lectures, and further research is expected in the future.

Objective: We compared appendiceal visualization on 2-mSv CT vs. conventional-dose CT (median 7 mSv) in adolescents and young adults and analyzed the undesirable clinical and diagnostic outcomes that followed appendiceal nonvisualization. Materials and Methods: A total of 3074 patients aged 15-44 years (mean ± standard deviation, 28 ± 9 years; 1672 female) from 20 hospitals were randomized to the 2-mSv CT or conventional-dose CT group (1535 vs. 1539) from December 2013 through August 2016. A total of 161 radiologists from 20 institutions prospectively rated appendiceal visualization (grade 0, not identified; grade 1, unsure or partly visualized; and grade 2, clearly and entirely visualized) and the presence of appendicitis in these patients. The final diagnosis was based on CT imaging and surgical, pathologic, and clinical findings. We analyzed undesirable clinical or diagnostic outcomes, such as negative appendectomy, perforated appendicitis, more extensive than simple appendectomy, delay in patient management, or incorrect CT diagnosis, which followed appendiceal nonvisualization (defined as grade 0 or 1) and compared the outcomes between the two groups. Results: In the 2-mSv CT and conventional-dose CT groups, appendiceal visualization was rated as grade 0 in 41 (2.7%) and 18 (1.2%) patients, respectively; grade 1 in 181 (11.8%) and 81 (5.3%) patients, respectively; and grade 2 in 1304 (85.0%) and 1421 (92.3%) patients, respectively (p < 0.001). Overall, undesirable outcomes were rare in both groups. Compared to the conventional-dose CT group, the 2-mSv CT group had slightly higher rates of perforated appendicitis (1.1% [17] vs. 0.5% [7], p = 0.06) and false-negative diagnoses (0.4% [6] vs. 0.0% [0], p = 0.01) following appendiceal nonvisualization. Otherwise, these two groups were comparable. Conclusion: The use of 2-mSv CT instead of conventional-dose CT impairs appendiceal visualization in more patients. However, appendiceal nonvisualization on 2-mSv CT rarely leads to undesirable clinical or diagnostic outcomes.

This study was conducted with a goal to identify the factors that determine radiology students' satisfaction with their major and to provide the basic data for efficient education and career guidance. The result indicated that the students' satisfaction with the professors' roles was high. However, overall, the level of satisfaction with the curriculum was found to be low. In addition, it was analyzed that there was a large gap between recognition and practice of self-directed learning. In the correlation analysis, the professors' roles were also found to be a very important factor. Based on the result, the professors' roles of center(teaching or state examination, students with questions etc.,), it was concluded that improvement of the radiology students' satisfaction with their major would help the students adapt themselves to the major and school successfully and develop a positive character to perform as professionals in the future.

The personality education of the existing university is mainly focused on occupational ethics education or basic education, but the purpose and method of the personality education program is changed in preparation for the 4th industry and the related occupational personality education program is needed. In Korea, however, there is a lack of research on the development of educational programs for occupational personalities that Health care workers should have. Therefore, this study aims to confirm the effect by developing and applying a program for occupational personality education for Health care workers required for the 4th Industrial Revolution based on case-based learning. In this study, general cases and occupational cases were developed, and research tools were developed to verify the effectiveness of the occupational personality education program. The program developed in this study was provided four times for 52 students in the second and third grades college and university. This study was performed with a single group pre-post design. The data were analyzed by means of mean, standard deviation, and paired t-test. By applying the program developed in this study, accountability, honesty, consideration, collaboration, communication, and competency were improved. This confirmed the positive effect of vocational character education

Purpose: This study was done to provide basic data for developing an in-service education program to improve nurses' quality. First, frequency of nursing activities and competency levels of emergency nurses according to their career ladders were compared through job analysis and then practical education programs were presented on based of the results. Method: Data were collected from 335 nurses working in emergency rooms in 31 tertiary hospitals. Data collection was done from September to November 2005 using the job analysis questionnaire. Results: There were 41 nursing activities that showed differences in frequency and 78 activities that showed differences in perceived competency level. Irrespective of emergency nurses' careers, activities that show high frequency but low competency were sputum liquefying therapy, assessment of cranial nerve function, identification of diagnostic radiology, and communication with various departments. In-service education content according to nurse's career ladders was presented by adding high frequency nursing activities and activities with low competency level even though having high frequency. Conclusion: There is a need to develop and provide in-service education programs, which consider nurses' difference in frequency and competency level for their career ladders.

This study was performed to understand the bacteriologic contamination level of radiological equipments which have frequent contacts with patients in the Department of Radiology of an university hospital in Busan area. Before sterilizing in-patient of the radiology rooms, MRSA, VRE, acinetobacter baumannii, candida albicans, and enterococcus sp. were detected. After sterilization, all the bacteria were not found. As examine times become longer, more bacteria were detected and after 7 hours, bacillus sp.(GPR), CNS, acinetobacter baumannii, and Enterococcus sp. were detected. After examining infected patients, bacillus sp.(GPR), VRE, enterococcus sp. CNS, and micrococcus sp. were detected and on the hands of radiological technologists, CNS, enterococcus sp. escherichia coli, and enterobacter sp. were detected. Similar species of bacteria were detected from each radiology room, but pseudomonas aeruginosa was detected on the handles of portable radiological equipments and the chair in the waiting room. Therefore, it is the most important to regularly sterilize radiological equipments and devices which have frequent contacts with patients and to sterilize them right after the use of infected patients in order to prevent the spread of infection. Also, thorough hand washing, education on infection and management for the characteristics of Department of Radiology should be performed for the systematic prevention of infection.

The purpose of this study was to discuss the required items and feasibility of medical records of radiological examinations performed by radiological technologists at medical institutions. An online survey was conducted to a total of 10,000 radiation-related workers, of which 1,026 (10.3%) responded. As a research method, self-made questionnaires were used. The online survey was conducted from September 10 to September 20, 2021 for the survey period. For response data, a Chi-square test was performed according to demographic characteristics using SPSS 27.0 version (IBM Inc., Chicago, Ill, USA), and it was judged to be significant when the P value was less than 0.05. The reliability of the questionnaire response was found to be Chronbach α=0.933. More than 90% of the medical records related to radiological examinations are necessary, and they answered that a curriculum, remuneration curriculum, and legal system for medical records should be prepared. More than 90% of the respondents agreed with the proposal of the Radiological Technologist Independent Act for legal preparation, and most of the information required for medical records is currently recorded in DICOM images. According to the demographic characteristics, the medical record requirement for radiological examination, curriculum, continuing education, and legislation were found to be higher with higher education and higher with longer working experience. In addition, most of the radiology departments showed a high demand for medical records, so most of them responded positively to the medical records requirements for radiological examinations. This study analyzed the medical record requirements for radiological examinations, and as shown in the results, medical record requirements for radiological examinations was found that most radiological technologists felt need for the new law and supported it. In addition, if the information recorded in the DICOM image is used, it is considered that medical records could be easily prepared without additional work by the radiological technologists.

To treat congenital heart disease, it is important to understand the anatomical structure correctly. Three-dimensional (3D) printed models of the heart effectively demonstrate the structural features of congenital heart disease. Occasionally, the exact characteristics of complex cardiac malformations are difficult to identify on conventional computed tomography, magnetic resonance imaging, and echocardiography, and the use of 3D printed models can help overcome their limitations. Recently, 3D printed models have been used for congenital heart disease education, preoperative simulation, and decision-making processes. In addition, we will pave the way for the development of this technology in the future and discuss various aspects of its use, such as the development of surgical techniques and training of cardiac surgeons.

This study was conducted to confirm the safety of the operator's radiation exposure in the micro PET-CT image acquisition experiment using the ¹⁸F-FDG. The usage of ¹⁸F-FDG and the exposure dose of handlers were measured at University B in Metropolitan City A, which uses ¹⁸F-FDG for micro PET-CT image acquisition. As a result of the measurement, the exposure dose is far below the effective dose limit of radiation workers, 50 mSv per year, and the equivalent dose limit of 500 mSv per year for hands, feet, and skin. has been measured Since these exposure doses can be further increased according to the number of times of use of ¹⁸F-FDG, it is judged that the exposure dose compared to the handling amount of ¹⁸F-FDG shown in this study can be used as reference data. In addition, as changed environments such as the use of materials other than unopened RI are occurring in education and research environments, such as the use of ¹⁸F-FDG at University B, radiation exposure with more interest in safety management by checking the factors of radiation exposure of the handler concerned We will always do our best to reduce it.
