Purpose: The purpose of this study was to identify the effects of a workbook program on percieved stress levels, maternal role confidence and breastfeeding practices of mothers of premature infants. Method: This study employed a quasi-experimental non-equivalent pre-and-post test to compare the two groups. Data was collected from 32 subjects from March 10. to September 5, 2003 at an NICU located in S. city. In the sample, fifteen mothers were in the experimental group and seventeen were in the control group. A workbook program was provided twice during a period from two-three days after the baby's admission to one week after the first intervention. The instruments used were the PSS and self confidence scale. Data was analyzed by means of frequency, SD, $x^2-test$, Fisher's exact test, Mann-Whitney test, and the Wilcoxon signed rank test. Result: There was a significant difference in perceived stress levels between the experimental and control group (U=2.366, p=.018). There was not a significant difference in maternal role confidence between the two groups (U=1.002, p=.316). There was a significant difference in breastfeeding practice between the two groups ($x^2=4.910$, p=.035). Conclusion: It is concluded that a program using a workbook has a positive effect on decreasing the perceived stress level and increasing breastfeeding practice.

Purpose: This study was done to identify learning experiences and self-confidence and to analyze nursing students' self-confidence according to learning experiences for core nursing skills (CNS). Method: Participants were 502 final year nursing students. Data were collected using a structured questionnaire and analyzed using descriptive statistics and t-test. Results: Over 60% of participants had practiced 15 items of the 24 CNS in the basic nursing lab (BNL). In clinical practice (CP), they had practiced five items but experienced only one item in a simulation lab (SL). Items with the highest confidence level were vital signs (4.69) followed by blood sugar test (4.60), pulse oximeter (4.38), and oral medication (4.12). Items with the lowest confidence level were blood transfusion (2.17) followed by enema (2.64) and indwelling catheterization (2.67). The group with CNS experience in the practice curriculum was generally more confident than the group with no experience. Self-confidences in some skills was significantly different depending on availability of SL, credits for BNL and CP, and presence of preceptors. Conclusion: Results indicate a need to develop practice education strategies such as changing the CP to practice-centered learning with preceptors and including well-designed SL to increase confidence of nursing students.

The performance of Precision Guided Missiles is estimated by using hit probability only, which is calculated by hits against total amounts of fires in current domestic live-fire tests. It has a limitation in judging the performance of all produced Precision Guided Missiles by using the calculated hit probability according to the result of live-fire test, because the overall characteristics of the produced Precision Guided Missiles are not considered. In other words, a method is needed to estimate the confidence level which is more reliable than simply calculated hit probability according to the result of live-fire test for guaranteeing the hit probability of Precision Guided Missiles by certain level, which is already being operated or produced. This paper introduces a method to estimate the confidence level of Precision Guided Missiles by minimum live-fire tests using Hypergeometric distribution and Bayes' rule suitable for the characteristics of Precision Guided Missiles, which are small production, high costs and unable to check whether the missile hits the target or not before the live-fire tests. Also, this paper suggests a reasonable confidence level for showing the performance of the Precision Guided Missiles using the results of live-fire tests and domestic and foreign literature, when the result of live-fire tests will be decided.

This study aimed to investigate the influence of career barriers on employment decisions among high school students specializing in beauty-related field. The subjects of this study were 339 students attending beauty-specialized high schools in Gwangju Metropolitan City and Jeollabuk-do, and a self-written questionnaire was employed for conducting the research. This survey was conducted from April 4 to April 18, 2022. A total of 380 questionnaires were distributed, and 350 responses were collected. Of these, 339 questionnaires were considered for the final analysis, as the remaining 11 had incomplete or insincere responses. The results of this study are summarized as follows. First, the career barriers affecting high school students in beauty-specialized schools were categorized into eight factors: lack of interest, economic difficulties, financial support, interpersonal challenges, job information, anxiety about future, conflict with others, and lack of self-clarity. Second, when assessing the impact of career barriers on employment decision-making, it was observed that the level of employment decision-making had a statistically positive (+) effect, and the lack of interest had a negative (-) effect on the level of employment decision-making. Next, the significance of the regression model, considering the specific factors of career barriers in relation to employment confidence, was established as p<.001. Variables such as a lack of interest, limited access to job information, and lack of self-clarity had a negative (-) effect on the level of employment confidence, with a significance level of 0.05.

The purpose of this study was to provide the basic data needed to plan the effective teaching design of scaling education and to measure the changes in students' confidence in performing scaling according to the number of scaling practices. Scaling education is presented as a core basic hygiene competency of dental hygienists and evaluated as the practical competency of dental hygienists. This study selected 48 third-year students from the department of dental hygiene at S University in Asan, and analyzed data from completed participant surveys. The degree of "confidence in facing the subject in clinical practice," "confidence in applying hand instrument to the subject," and "confidence in applying ultrasonic instruments to the subject" was assessed on a five-point Likert scale. The difference in confidence was analyzed during five practice sessions. Each response was compared using frequency analysis, chi-square test, and repeated measurement ANOVA. Students who complained of a lack of confidence in the 14.6%, 25.0%, and 12.5%, respectively, in face-to-face practice, hand instruments, and ultrasonic instrument application responses. The more the practice was repeated, the more confident students were in all three categories, and the more statistically significant (p<0.001). As the number of scaling practice sessions increased, students' confidence in performing scaling also improved. In particular, the level of self-confidence was higher after the third practice session when compared to the first session. Therefore, it is necessary to design effective courses for teaching scaling practices so that at least three repetitive practice periods can be provided in clinical dental hygiene practices.

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)
