Purpose: This study investigated the effects of 1 year of training on imaging diagnosis, using static ultrasonography (US) salivary gland images of Sjögren syndrome patients. Materials and Methods: This study involved 3 inexperienced radiologists with different levels of experience, who received training 1 or 2 days a week under the supervision of experienced radiologists. The training program included collecting patient histories and performing physical and imaging examinations for various maxillofacial diseases. The 3 radiologists (observers A, B, and C) evaluated 400 static US images of salivary glands twice at a 1-year interval. To compare their performance, 2 experienced radiologists evaluated the same images. Diagnostic performance was compared between the 2 evaluations using the area under the receiver operating characteristic curve (AUC). Results: Observer A, who was participating in the training program for the second year, exhibited no significant difference in AUC between the first and second evaluations, with results consistently comparable to those of experienced radiologists. After 1 year of training, observer B showed significantly higher AUCs than before training. The diagnostic performance of observer B reached the level of experienced radiologists for parotid gland assessment, but differed for submandibular gland assessment. For observer C, who did not complete the training, there was no significant difference in the AUC between the first and second evaluations, both of which showed significant differences from those of the experienced radiologists. Conclusion: These preliminary results suggest that the training program effectively helped inexperienced radiologists reach the level of experienced radiologists for US examinations.

The purpose of this study is to examine relations between the job satisfaction and separation intent of radiologists from secondary medical institutes, providing basic information needed to earlier prevent radiologists' separation, improve their quality and effectively manage them. 1. The subjects' job satisfaction was 2.32 points in mean score, which was below the average. 2. Concerning difference in job satisfaction among the subjects in accordance with their demographic characteristics, it was found that radiologists are significantly different among them in job satisfaction according to their age and position. 3. The surveyed radiologists' intent of separation was 2.89 points in mean score, which was not significantly high. 4. Concerning difference in the intent of separation among the participants in accordance with their demographic characteristics, it was found that radiologists are significantly different among them in the intent of separation according to their age, marital status, position and average monthly income. 5. There were significant correlations between the subjects' job satisfaction and intent of separation. In other words, the higher radiologists are in job satisfaction, the lower they are in the intent of separation.

Objectives: The purpose of this study was to evaluate the optimal distance and angle of observers by modulation transfer functions(MTFs) and receiver operating characteristics(ROCs), Material and Methods: Digital periapical radiograms were taken from 43 patients who have dental diseases(19 patients : dental caries. 12 patients : periapical lesions, 12 patients : periodontal diseases). Segmental images(4×4cm) were evaluated by 4 MTFs and ROC analysis. Results: The optimal distance(magnification) using MTF by Mannos & Sakrison was 12.97. and those by Nill. Ngan and Rao were 8.39, 4.78. 5.84 respectively. The optimal distance obtained from 4 radiologists by ROC analysis was 32cm(Az value: 0.89). and it was 40cm(Az value: 0.78) from 4 non-radiologists. There were significant differences of Az values between 4 radiologists and 4 non-radiologists at 24. 32 and 40cm (P<0.05). No significant differences of optimal distances were observed using 4 MTFs among +20, +10, 0, -10, -20 degrees(P>0.05). The optimal angle obtained from 4 radiologists by ROC analysis was +20 degree(Az value: 0.91). and no significant differences of Az values were observed among +20, +10, 0, -10 and -20 degrees(P>0.05). The optimal angle obtained from 4 non-radiologists by ROC analysis was 0 degree(Az value : 0.81). and no significant differences of Az values were observed among +20, +10, 0, -10 and -20 degrees(P>0.05). And there was significant difference of Az value between 4 radiologists and 4 non-radiologists at +20 degree(P<0.05). but no significant differences of Az values were observed among +10, 0, -10 and -20 degrees(P>0.05).

The purpose of this study is to grasp the image of radiologists perceived by college students of radiology. The survey subjects of this study were selected college students with major in radiology with 3-year system who are attending universities where are located in Daegu and Gyeongbuk area. As for distribution and collection of questionnaire, the objective of research was explained from April 2, 2012 to April 30. 220 people's questionnaires were finally analyzed with a self-administrative method after being widely distributed. Statistical analysis was carried out frequency analysis, t-test, ANOVA, and correlation analysis. To examine factors of having influence upon the image of radiologists, the multiple regression analysis was carried out. As for survey subjects' general characteristics, gender was indicated to be 58.2% for men and 41.8% for women. School year accounted for 38.2% for freshman, 29.1% for sophomore, and 32.7% for junior. Age was the largest in under 21 years old with 43.6%. The next was in order of over 23 years old with 32.7% and 22 years old with 20%. As a result of research, the image of radiologists was being perceived positively. The radiologist was being recognized as a specialist who is sincere oneself and has strong responsibilities, does valuable and worthwhile work, and has the matured professional knowledge. However, the individual image of radiologists was a little negative. Accordingly, to promote the individual image of radiologists, a specific and positive strategy is needed for approaching people as the specialized job with autonomy and responsibility as well as radiologist oneself.
