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.

The purpose of the study was to explore effective satisfaction factors for continuous partnerships between fashion companies and artists. A questionnaire was developed by the researchers and results were collected from a total of 273 people who were working for a fashion company or working as an artist. Data was analyzed by the use of a frequency test, a reliability test, an exploratory factor analysis and a structure equation model analysis using AMOS 18.0. The results of the study were as follow. First, profitability and adequacy had significant effects, but awareness had no effect on confidence concerning the partnership. Second, awareness and profitability showed significant effects, but adequacy showed no effect on the flow among those in the partnership. Third, confidence had a significant effect on flow. Fourth, among the partnership factors, confidence and flow had significant effects on partnership satisfaction. Fifth, flow showed a significant effect on the intent for a continuous partnership, but confidence showed no effect.

본 연구는 간호학생 실습교육을 위해 시나리오 기반 입원관리 가상현실(Scenario-based Admission Management Virtual Reality, 이하 SAM VR) 콘텐츠를 개발한 후 효과성을 검증하기 위해 수행되었다. 연구에 사용된 SAM VR 콘텐츠는 한국간호교육평가원에서 제시한 표준실무 절차에 따라 기어 VR과 스마트폰을 활용하여 10분 분량으로 개발되었다. SAM VR 콘텐츠 활용한 실습교육을 받은 실험군 30명은 실습교육 후에 학습몰입감, 학습자신감 및 학습만족도가 통계적으로 유의하게 상승했다(p<.001). 전통적인 방식으로 실습교육을 받은 대조군은 실습교육 후에 학습자신감은 상승하였으나(p<.005) 학습몰입감과 학습만족도에는 변화가 나타나지 않았다(p>.005). SAM VR 콘텐츠는 간호학생의 학습몰임감, 학습자신감과 학습만족도에 효과적인 실습교육 콘텐츠임이 검증되었다.

본 연구는 수술실 신규간호사의 웹 기반 동영상 프로그램 선택속성이 학습 몰입을 매개로 차후 간호 수행능력에 관한 확신에 미치는 영향을 검증하는 것이 목적이다. 연구대상은 인천 및 경기도 소재 대학병원의 수술실 근무 중인 간호사를 대상으로 하였으며, 250개의 표본을 분석에 활용하였다. 연구방법은 구조화된 설문지를 사용하여 2019년 7월부터 8월까지 수집되었다. 참가자들은 인천과 경기에 있는 대학병원 수술실 250명의 간호사이다. 수집 된 데이터는 IBM SPSS Statistics 25.0과 AMOS 24.0을 사용하여 분석하였으며, 구조모형을 통해 위에 적합도 지표를 기반으로 직접효과와 간접효과를 측정하였다. 연구 결과, 수술실 신규간호사는 수술과 1차적으로 직결되는 위생 안전요인과 환자 관리요인을 상대적으로 더욱 중요하게 인지하였다. 학습 몰입을 통하여 차후 간호 수행능력에 관한 확신이 있었고, 위생 안전요인의 경우 학습 몰입이 없어도 수술실 신규간호사가 중요성을 인지하여 차후 간호 수행능력에 관한 확신에 긍정적 영향이 미침을 검증하였다. 따라서 향후 시각적 효과에 더 비중을 둔 웹 기반 동영상 프로그램 구성을 통해 간호의 위생 안전요인뿐만 아니라 환자 관리요인 그리고 간호 관련 요인 모두가 환자의 생명과 회복에 핵심적 단계임을 신규간호사에게 적합하게 이해시킬 필요가 있다.

Measurement uncertainty should be evaluated according to ISO/IEC 17025. In Flow measurement area, uncertainty evaluation scheme was applied to the reference flow meter, sonic nozzle. Uncertainty was calculated by evaluating various uncertainty factors affected in flow measurement. The expanded uncertainty of the sonic nozzle was 0.21 % (confidence level of 95 %). This evaluation example will be useful in flow measurement uncertainty determination of other flow meters.

The new piston prover was developed and the flow measurement uncertainty of this piston prover was evaluated according to ISO/IEC 17025. The laser interferometer was employed to measure accurately the testing time. Uncertainty was calculated with evaluation of various uncertainty factors affected in flow measurement. The expanded uncertainty(U) of the piston Over was $1.3{\times}10^{-3}$ (at the confidence level of $95\%$). This evaluation example will be useful in flow measurement uncertainty determination of other gas flow measurement system.
