Objectives: In most retrospective studies, the clinical performance of restorations had not been considered in survival analysis. This study investigated the effect of including the clinically unacceptable cases according to modified United States Public Health Service (USPHS) criteria into the failed data on the survival analysis of direct restorations as to the longevity and prognostic variables. Materials and Methods: Nine hundred and sixty-seven direct restorations were evaluated. The data of 204 retreated restorations were collected from the records, and clinical performance of 763 restorations in function was evaluated according to modified USPHS criteria by two observers. The longevity and prognostic variables of the restorations were compared with a factor of involving clinically unacceptable cases into the failures using Kaplan-Meier survival analysis and Cox proportional hazard model. Results: The median survival times of amalgam, composite resin and glass ionomer were 11.8, 11.0 and 6.8 years, respectively. Glass ionomer showed significantly lower longevity than composite resin and amalgam. When clinically unacceptable restorations were included into the failure, the median survival times of them decreased to 8.9, 9.7 and 6.4 years, respectively. Conclusions: After considering the clinical performance, composite resin was the only material that showed a difference in the longevity (p < 0.05) and the significantly higher relative risk of student group than professor group disappeared in operator groups. Even in the design of retrospective study, clinical evaluation needs to be included.

Students must be familiar with clinical skills before starting clinical practice to ensure patients' safety and enable efficient learning. However, performance is mainly tested in the third or fourth years of medical school, and studies using the validity framework have not been reported in Korea. We analyzed the validity of a performance test conducted among second-year students classified into content, response process, internal structure, relationships with other variables, and consequences according to Messick's framework. As results of the analysis, content validity was secured by developing cases according to a pre-determined blueprint. The quality of the response process was controlled by training and calibrating raters. The internal structure showed that (1) reliability by generalizability theory was acceptable (coefficients of 0.724 and 0.786, respectively, for day 1 and day 2), and (2) the relevant domains had proper correlations, while the clinical performance examination (CPX) and objective structured clinical examination (OSCE) showed weaker relationships. OSCE/CPX scores were correlated with other variables, especially grade point average and oral structured exam scores. The consequences of this assessment were (1) making students learn clinical skills and study themselves, while causing too much stress for students due to lack of motivation; (2) reminding educators of the need to apply practical teaching methods and to give feedback on the test results; and (3) providing an opportunity for faculty to consider developing support programs. It is necessary to develop the blueprint more precisely according to students' level and to verify the validity of the response process with statistical methods.

Purpose: This study was conducted to test a path model for the factors related to undergraduate nursing students' clinical practicum stress, based on Lazarus and Folkman's stress-coping model. Methods: This study utilized a path analysis design. A total of 235 undergraduate nursing students participated in this study. The variables in the hypothetical path model consisted of clinical practicum, emotional intelligence, self-efficacy, Nun-chi, and nursing professionalism. We tested the fit of the hypothetical path model using SPSS/WIN 23.0 and AMOS 22.0. Results: The final model fit demonstrated a satisfactory statistical acceptance level: goodness-of-fit-index=.98, adjusted goodness-of-fit-index=.91, comparative fit index=.98, normed fit index=.95, Tucker-Lewis index=.92, and root mean square error of approximation=.06. Self-efficacy (${\beta}=-.22$, p=.003) and Nun-chi behavior (${\beta}=-.17$, p=.024) were reported as significant factors affecting clinical practicum stress, explaining 10.2% of the variance. Nursing professionalism (${\beta}=.20$, p=.006) and self-efficacy (${\beta}=.45$, p<.001) had direct effects on emotional intelligence, explaining 45.9% of the variance. Self-efficacy had indirect effects on Nun-chi understanding (${\beta}=.20$, p<.001) and Nun-chi behavior (${\beta}=.09$, p=.005) through emotional intelligence. Nursing professionalism had indirect effects on Nun-chi understanding (${\beta}=.09$, p=.005) and Nun-chi behavior (${\beta}=.09$, p=.005) through emotional intelligence. The variables for self-efficacy and nursing professionalism explained 29.1% of the Nun-chi understanding and 18.2% of the Nun-chi behavior, respectively. Conclusion: In undergraduate nursing education, it is important to identify and manage factors that affect clinical practicum stress. The findings of this study emphasize the importance of Nun-chi, self-efficacy, emotional intelligence, and nursing professionalism in the development of an educational strategy for undergraduate nursing students.

This study investigated the effects of emotional intelligence and ego resilience on the clinical practice of nursing students. The subjects of this study were 203 college students who were in the third year of a nursing college in G province, Korea from June 12 2018 to August 29, 2018. The data was analyzed using means, standard deviations, Pearson correlation coefficients, t-tests, ANOVA, and multiple regression analysis of the SPSS 26.0 statistical program. The emotional intelligence, ego resilience, and clinical practice showed significant differences according to students' satisfaction with the nursing department, and these variables all have significant positive correlation. The regression analysis showed that emotional intelligence (β=.23, p<.001) and ego-resilience (β=.20, p<.05) were the significant variables affecting the clinical practice of nursing students, and these variables explained 15% of adaptation to their clinical practice (F=18.71, p<.001). Based on the results of this study, it is necessary to develop and utilize a program to enhance emotional intelligence and self-elasticity as a way to improve the adaption to clinical practice of nursing students.

Purpose: This study was performed to investigate the perceived relationship among professional self-concept, head nurse's leadership, and nursing clinical competency by clinical nurses. Methods: This study was a cross-sectional survey. Participants were 601 nurses working at the five general hospitals in four provincial cities, Gyeungbuk, Korea. Data were collected from July 14, 2010 to August 31 and analyzed by SPSS/PC ver 18.0 programs. Results: Professional self-concept and head nurse's leadership were slightly above the middle average, but nursing clinical competency was good. According to participants' age, marital status, job satisfaction, and length of service, there were perceptional differences in professional self-concept, head nurse's leadership, and nursing clinical competency. Nursing clinical competency could be explained by head nurse's leadership, professional self-concept, job satisfaction and length of service. Head nurse's leadership was independent variable affecting nursing clinical competency, professional self-concept was partial mediating variable, and job satisfaction and length of service were extraneous variables. Conclusion: It is concluded that head nurse's leadership is more important than professional self-concept to improve nursing clinical competency. Nursing managers should plan various strategies to improve head nurse's leadership and professional self-concept, to increase clinical nurses' job satisfaction and length of service.

Purpose: This exploratory study aims to identify various factors influencing the level of nursing professionalism among nursing students. Methods: This study surveyed 246 senior nursing students in U city with a structured self-report questionnaire analyzed with SPSS 22.0. Results: The average scores for clinical practice learning environment, self-leadership, clinical practice belonging, and nursing professionalism were 3.16, 3.77, 3.53, and 3.60, respectively. There were significant differences in nursing professionalism according to the subjects' satisfaction with the nursing major and satisfaction with the amount of nursing. The most significant factors affecting nursing professionalism included clinical practice learning environment (${\beta}=.40$, p<.001), self-leadership (${\beta}=.21$, p=.001), and clinical practice belonging (${\beta}=.16$, p=.011). These variables explained 39% of the total variance in nursing professionalism. Conclusion: Clinical practice learning environment, self-leadership, and clinical practice belonging are factors in the nursing professionalism of senior nursing students. Collaborative efforts by universities and clinics are needed to improve the clinical training environment and to produce good nurses. Particularly since few studies have been conducted in Korea on clinical practice belonging, it is meaningful to explore how clinical practice belonging affects nursing professionalism.
