Purpose: The purpose of this study was to identify changes in image of nurses of nursing students before and after their first clinical practice. Methods: The survey was performed to 60 nursing students in one university in Goseong-gun, Gangwon-do. All participants had their first clinical practice for 8 weeks at four general hospitals in Seoul. The data were collected by questionnaires and were analyzed with frequency, independent t-test, one-way ANOVA using SPSS 19.0. Results: After the first clinical practice, the mean score ($4.05{\pm}0.85$) of the image of nurse was slightly higher than that of the image ($4.03{\pm}0.93$) before the clinical practice. However, there was no statistical significance in the scores between before and after the clinical practice (t=-0.55, p=.589). In four subcategories, before the first clinical practice, professional image was the highest followed by traditional, personal, and social image in order but after the clinical practice, professional image was the highest followed by traditional, social, and personal image in the mean scores of the image of nurse. Conclusion: The findings of the study may be a basis for expanding nursing practice and education related to image of nurse.

The purpose of this study was to identify how nurse's image was perceived by nursing college students. The subjects included were 315 students experienced clinical practice during $20{\sim}22$ weeks and 134 students not with a total of 449 nursing students in Gwangju and Chonnam. The data were collected from November 21 to December 5, 2001 by the structured questionnaires. The research tool was measured by 30 items divided into four dimensions; traditional, professional, social and personal image of nurse. Cronbach $\alpha$ for the tool of nurse's image was 0.8960. The data were analysed by SPSS 8.0 for Windows program using frequency, percentage, mean, standard deviation, t-test, ANOVA and scheffe. The results of this study were as follows; 1. In the nurse's image related to general characteristics, there were significant differences for school graduation, applicative motivation, interpersonal relationship and image forming factor. 2. In the Image forming factors, nursing college students perceived the nurse's image by visiting hospital or admission(37.9%), watching TV(25.8) and others; nurses' appearance during clinical experience(16.3). 3. The mean score for nurse's image of clinical experience group (2.76$\pm$0.28) was lower than that of non-clinical experience group(2.89$\pm$0.31) in significance (t=4.319, p=0.000). 4. In the nurse's image according to clinical experience, there were significant differences for traditional, professional, social, personal image between two groups and the lower mean scores were found in the clinical experience group in all dimensions. The ranks of dimensions were professional image(3.08), traditional image(2.76), social image(2.65), the personal image(2.59) in clinical experience group, whereas professional image(3.21), traditional image(2.93), social image(2.75), personal image(2.71) for non-clinical experience group.5. The high score items of nurse's image were 'worthwhile work(3.48)', 'always working hard(3.30)', 'profession(3.17)', 'strong responsibility toward work(3.08)', 'have a high technical skill(3.05)' in clinical experience group and 'worthwhile work(3.69)', 'always working hard(3.28)', 'clean and decent(3.22)', 'profession(3.21)', 'have a bountiful professional knowledge(3.18)' in non-clinical experience group. 6. The highest mean score for nurse's image related to the image forming factors was 86.8 by novels or literature and the second highest was 84.3 by visiting hospital or admission. And others(mean=82.1)was the most negative nurse's image by clinical experience. In conclusion, nurse's image perceived by nursing college students will be the mirror of themselves. And clinical experience will be the important opportunity to form the professional image with white uniformed nurses in future. Therefore it is important for clinical nurses to play professional roles rightly so that nursing students could form positive nurse's image.

Objective: To develop a machine learning (ML) pipeline based on radiomics to predict Coronavirus Disease 2019 (COVID-19) severity and the future deterioration to critical illness using CT and clinical variables. Materials and Methods: Clinical data were collected from 981 patients from a multi-institutional international cohort with real-time polymerase chain reaction-confirmed COVID-19. Radiomics features were extracted from chest CT of the patients. The data of the cohort were randomly divided into training, validation, and test sets using a 7:1:2 ratio. A ML pipeline consisting of a model to predict severity and time-to-event model to predict progression to critical illness were trained on radiomics features and clinical variables. The receiver operating characteristic area under the curve (ROC-AUC), concordance index (C-index), and time-dependent ROC-AUC were calculated to determine model performance, which was compared with consensus CT severity scores obtained by visual interpretation by radiologists. Results: Among 981 patients with confirmed COVID-19, 274 patients developed critical illness. Radiomics features and clinical variables resulted in the best performance for the prediction of disease severity with a highest test ROC-AUC of 0.76 compared with 0.70 (0.76 vs. 0.70, p = 0.023) for visual CT severity score and clinical variables. The progression prediction model achieved a test C-index of 0.868 when it was based on the combination of CT radiomics and clinical variables compared with 0.767 when based on CT radiomics features alone (p < 0.001), 0.847 when based on clinical variables alone (p = 0.110), and 0.860 when based on the combination of visual CT severity scores and clinical variables (p = 0.549). Furthermore, the model based on the combination of CT radiomics and clinical variables achieved time-dependent ROC-AUCs of 0.897, 0.933, and 0.927 for the prediction of progression risks at 3, 5 and 7 days, respectively. Conclusion: CT radiomics features combined with clinical variables were predictive of COVID-19 severity and progression to critical illness with fairly high accuracy.

The image intensifier is the key component which determines the imaging characteristics in a fluoroscopic imaging system. A system performance program for clinical evaluation of two image intensifiers, that is simple, non-invasive and time effective, was described. Tests were grouped into three headings: x-ray generator, image quality, and collimation. For the x-ray generator, the kVp accuracy and the automatic exposure control operation were compared. Low- and high-contrast resolution measurements, and mesh pattern study belong to the image quality tests and those tests were performed for the video monitor and photospot images. For the collimation, usable field diameter and image distortion of image intensifiers were measured and quantified. The procedures and the results are hoped to be used for the clinical evaluation of system performance and/or acceptance tests for image intensifiers.
