The objective of study is to evaluate highway capaicty estimation alternative and to develop capacity from statistical distribution of observed traffic flow. Speed-Volume relation is analyzed from vehicle's headway distribution eliminating the long headway by confidence intervals 99%, 95%, 90%. Capacity estimate alternatives were evaluated from 95% , 90%, 85% level of cummulative distribution of observed hourly traffic flow adjusted to confidence intervals. The result of investigation revealed that maximum hourly rate of flow is 2, 130pcu at confidence interval of 995, 2, 233pcu at 95%, 2, 315pcu at 90% respectively. Compared to the capacity of 2, 200pcu per hour per lane used in HCM and KHCM(Korea Highway Capacity Manual), capa챠y appears to correspond to confidence interval of 95%. Using the traffic flow rate at confidence interval of 95% the maximum hourly flow rate is 2, 187pcu at 95% of cummulative volume distribution, 2, 153pcu at 90%, 2, 215pcu at 85%. The study suggests that raional capacity esimation alternative is to take the 95% of cummulative distribution of observed hourly traffic flow at 95% confidence headway interval eliminating 5% long headway.(i.e. 95-95 rule)

Purpose: This study investigated the relationship between satisfaction with fundamental nursing skills practicum, confidence in fundamental nursing skills performance and learning flow, and examined factors influencing satisfaction with practicum programs of fundamental nursing skills in face-to-face and online classes for nursing students amid COVID-19. Methods: The subjects of the study were 229 junior nursing students from two colleges of nursing located in D and C city, respectively. The collected data were analyzed with descriptive statistics, independent t-test, ANOVA, Kruskal-Wallis test, Pearson's correlation and hierarchical multiple regression, using SPSS/WINdows 23.0. Results: The subjects' satisfaction with practicum showed a high positive correlation with confidence in performance (r=.55, p<.001) and learning flow (r=.70, p<.001) in face-to-face classes, and their satisfaction with practicum showed a high positive correlation with confidence in performance (r=.56, p<.001) and learning flow (r=.73, p<.001) in online classes. The factors affecting the subjects' satisfaction with practicum were learning flow (β=.51, p<.001) and confidence in performance (β=.30, p<.001) for face-to-face classes, and motivation for application (β=.14, p=.034), learning flow (β=.58 p<.001) and confidence in performance (β=.19, p=.015) for online classes. These factors explained 53% and 60% of the satisfaction with practicum in face-to-face classes (F=23.07, p<.001) and online classes (F=20.66, p<.001), respectively. Conclusion: Learning flow and confidence in performance should be considered when developing learning strategy programs to improve nursing students' satisfaction with fundamental nursing skills practicum in both face-to-face and online classes.

This research paper looks into the interrelationships between physical self-perception, performance confidence, physical self-efficacy, dance flow and dance performance satisfaction with dance major students as the central figure. It also looks into the needs of dance majors, and in order to understand the accomplishment in dance and performance satisfaction, studies were carried out on 313 dance major students. According to this research, firstly, in the difference from physical self-perception according to general characteristics, specialists that major in dance have perception about one's body when specialists have a longer dancing time and experience. In the relationship between dancing experience and self-efficacy it could be seen that self-efficacy is postirely comelated with dancing experience. Also, in dance performance satisfaction, the more experience or time one encounters dance the higher the satisfaction. Secondly, when looking at the effect physical self-perception has on performance, confidence and self-efficacy, among the lower factors of physical self-perception, sports competence, condition and fitness have notable amount of effect on performance confidence. Thirdly, when looking at the effect on physical self-perception and self-efficacy, sports competence and condition have a certain amount of influence on body competence. Also sports competence, condition and fitness have some influence on physical confidence. Fourth, when looking at the influence of performance confidence and self-efficacy on dance flow, performance confidence, body competence and physical attraction have some effect on behavioral devotion. Lastry looking at the influence dance flow has on dance performance satisfaction, only behavioral devotion has much influence on dance performance satisfaction.

This study was attempted to verify the mediating effect of perceived interaction in the relationship between learning flow and problem-solving confidence of nursing students who experienced team-based nursing practice learning. The subjects of this study were 148 senior nursing students who experienced team-based nursing practice learning classes. Data were collected using a structured questionnaire. For data analysis, descriptive statistics, Pearson correlation analysis, hierarchical multiple regression analysis, and Sobel test were conducted. The results of the study showed that nursing students' learning flow was 3.58±0.56 points, perceived interaction was 4.06±0.56 points, and problem-solving confidence was 3.67±0.53 points on average. Learning flow of nursing students showed a positive correlation with perceived interaction(r=0.63, p<.001) and problem-solving confidence(r=0.74, p<.001). Perceived interaction showed a partial mediating effect in the relationship between learning flow and problem-solving confidence(z=5.31, p<.001). It may be necessary to develop programs to improve nursing students' learning flow, perceived interaction, and problem-solving confidence, and to improve their clinical practice ability to solve nursing problems in various nursing settings.

This study aimed to examine the effect of selected factors on confidence in nursing performance among new operating room nurses, with a focus on the mediating effect of learning flow. Data was collected from July to August 2019 using structured questionnaires. The participants were 250 new operating room nurses from university hospitals located in Incheon and Gyeonggi. The collected data was analyzed using the IBM SPSS Statistics 25.0 and AMOS 24.0. Structural equation modeling was performed to examine the effect of the selected factors namely web-based video programs on confidence in nursing performance, and the mediating effect of learning flow. Results: The factors of 'hygiene & safety' and 'patient care' from the web-based video programs had a positive effect on the learning flow. The higher the learning flow of the nurses, the greater their confidence in nursing performance. Just the 'hygiene & safety' factor significantly increased nursing performance. Conclusion: The study results suggest that new nurses perceive that 'hygiene & safety' is an important factor in building their confidence in nursing performance, even without the learning flow. Therefore, it is necessary to develop web-based video programs based on nurses' needs and to emphasize the importance of postoperative care.
