ABSTRACT
Purpose@#To analyze the findings and serial changes in chest CT lesions in 123 symptomatic patients with coronavirus disease 2019 (COVID-19). @*Materials and Methods@#From February 19 to April 7, 2020, a total of 123 confirmed COVID-19 patients (male, 44; female, 79; mean age, 59.2 ± 18.6) were enrolled in this retrospective study.A total of 234 CT scans were reviewed for the following patterns: acute alveolar insult (AAI) patterns: ground-glass opacity (GGO), crazy-paving appearance, mixed pattern, and consolidation; organizing pneumonia (OP) patterns: perilobular patterns, band opacity, curvilinear opacity, reversed halo opacity, and small nodular consolidation; resolving patterns: pure GGO, remnant curvilinear, small nodular consolidation, and serial changes of lung abnormalities. We compared the proportions of AAI pattern, OP pattern, or resolving pattern with time progression and analyzed the association between the patterns and disease severity using Pearson chi-square and Fisher’s exact test. @*Results@#Predominant CT patterns were AAI pattern (87%) in the early hospital period group (0-10 days, after the onset of symptoms), OP pattern (45.7%) in the later hospital period group (after 10 days), and resolving pattern in discharge and follow-up group (47.2% and 84.8%, respectively). The difference in the proportions of predominant CT patterns with time progression was statistically significant (p < 0.001, Pearson’s chi-square test). No statistically significant association was observed between the patterns and disease severity (p = 0.055, Fisher’s exact test). No fibrous changes in the lesions were observed on follow-up CT scans. @*Conclusion@#The serial CT scans of COVID-19 patients showed the spectrum of COVID pneumonia CT manifestations as different phases of lung injury and repair.

ABSTRACT
PURPOSE: This study aims to examine the influence of vitamin D and calcium on depression and cognitive function of the elderly living alone in a city. METHODS: The participants were registered in eight senior centers in S city and they had lived alone. Data were collected between November 28, 2014 and March 7, 2015. A total of 155 people participated in data collection to measure the serum vitamin D, the serum calcium, depression, and cognitive function. The data were analyzed with t-test, ANOVA, Pearson's correlation and multiple regression analysis. RESULTS: There were significant differences in depression according to gender and perceptions of health status. Depression correlated significantly with the serum calcium and perceptions of health status, and a stepwise regression analysis showed that the perceptions of health status were significant. There were significant differences in cognitive function according to education level and age. Cognitive function correlated significantly with the serum vitamin D and a stepwise regression analysis showed that education level and age were significant. CONCLUSION: Consequently, elderly people with poor perceptions of their health status need a depressive intervention program and those with a higher age and lower level of education need a cognitive function intervention program.

PURPOSE: The purpose of this study was to identify a causal relationship among major satisfaction, career decision autonomy, and career search behavior of nursing college students in clinical practice experience. METHODS: Data were collected using a self-reported questionnaires from 197 nursing students in S city from December 1 to 23, 2016. These were then analyzed by descriptive statistics, ANOVA, t-test, Pearson correlation coefficient, and multiple regression using SPSS/PC+ program. RESULTS: The results suggest that major satisfaction was correlated with career decision autonomy; likewise, major satisfaction was correlated with career search behavior. The factors influencing career search behavior were grades and major satisfaction. CONCLUSION: It is necessary to develop a learning method considering interest and aptitude to increase the satisfaction of the major and to apply the various programs to understand the self and the work environment so as to determine how desirable the course will be.
