Purpose: The purpose of this study was to determine the effects of infection control education, knowledge, attitude and self-confidence of student nurses, regarding nosocomial infection control. Method: This was a nonequivalent control group nonsychronized design. The participants were 83 student nurses who were conveniently assigned to the experimental or a control group. The data were collected from March 5 to June 11, 2008 and analyzed based on Fisher's exact test and t-test. Result: The 1st hypothesis, "Posttest nosocomial infection control knowledge scores for the experimental group will be higher than scores for the control group" was supported (t=2.057, p=.043). The 2nd hypothesis, "Posttest nosocomial infection control attitude scores for the experimental group will be higher than those for the control group" was not statistically significant (t=.466, p=.643), The 3rd hypothesis, "Posttest nosocomial infection control self-confidence scores for the experimental group will be higher than those for the control group" was not statistically significant (t=2.290 p=.025). Conclusion: This infection control education was effective in increasing the levels of knowledge and self-confidence for student nurses regarding nosocomial infection control.

Purpose: The purpose of this study was to provide basic data for the development of health and safety programs by examining child-care teacher's knowledge, self-confidence and practice concerning the health and safety of children under their care. Method: The participants were 72 teachers from 15 child care centers in Seoul City and Chung-Nam Province. Data were collected using self-report questionnaires. Data were analyzed using descriptive statistics, ANOVA and Pearson correlation coefficients with SPSS 12.0 Win program. Results: The mean score for self-confidence was lower than knowledge and practice. Self-confidence score about emergency care for falls, fractures and resuscitation were lowest. For safety knowledge, scores about facility and environment were lowest. For health knowledge, scores about disease and symptoms were lowest. For practice, scores about seat belts and safe furniture arrangement were lowest. Significant correlations were found between practice and self-confidence. There were significant differences in the degree of knowledge according to education, and in practice according to age. Conclusions: Health and safety education programs for child care teachers are necessary for the promotion of knowledge, self-confidence and practice in health and safety. The results suggest that health and safety education program should be provided systematically and continuously for child care teachers.

Purpose: The purpose of this study was to determine relationships between academic achievement, clinical competence, and confidence in the clinical performance of nursing students, and to identify factors that influence them. Methods: This was a descriptive correlation study. Data were collected from 118 nursing students at a nursing college in Seoul. One-way variance analysis, Pearson's correlation coefficient, and multiple linear regression analysis were used to examine relationships between academic achievement, clinical competence, and confidence in clinical performance. Results: Clinical competence was related to academic achievement in students' previous semester and to students' academic scores in a fundamental of nursing course. Clinical competence showed a weak positive correlation with academic achievement in students' previous semester and academic scores in a fundamental of nursing course in both evaluations by the professor and students' self-evaluations. However, confidence in clinical performance had no significant correlation with academic achievement. The factor affecting the clinical competence was academic scores in a fundamental of nursing course, and factors affecting confidence in clinical performance were health status, personality, major suitability, and class satisfaction in a fundamental of nursing skills course. Conclusion: These findings indicate that students with high academic achievement have better clinical performance, but confidence in clinical performance is not related to academic achievement.

This study is descriptive research to investigate frequency of performance, self-confidence and performance assessment scores of core nursing skills by 227 nursing students. As the result of this study, they who experienced more than 10times in clinical practice was V/S and they never experienced items such as transfusion, enema and T-tube care. For pre self-confidence, they had the highest V/S and the lowest transfusion. For post self-confidence, they had the lowest IM. As a result of the evaluation, oxygen therapy with nasal cannula was measured highest, and IM was measured lowest. Frequency of performance had positive correlations with self-confidence(r=0.414, p<.001) and performance assessment scores(r=0.322, p=.007). Self-confidence with performance assessment scores had positive correlation(r=0.281, p=.003). Study results suggested that clinical practice is carried out, non-invasive, simple measurements, and they had low self-confidence of the items with low frequency of performance, so convergency training methods to complement this point are needed.

Purpose: The purpose of this study was to develop a first aid coaching program (FACP) and to investigate its effects on the first aid knowledge, confidence, and performance of childcare teachers. Methods: A Delphi survey that included 16 experts was used to develop the FACP. A total of 60 participants were included to test the effectiveness of the program. The FACP developed using the survey results focused on improving first aid knowledge, confidence, and performance using a coaching-based method. First aid and cardiopulmonary resuscitation (CPR) performance was assessed using 39 items from the program content. Results: Using a 3-round Delphi survey, 6 areas and 42 detailed topics for group and individual coaching programs were developed. The knowledge scores were significantly higher in the experimental group than in the control group (t=4.24, p=.001). The confidence scores were significantly higher in the experimental group than in the control group (F=3.89, p<.001). The performance scores were significantly higher in the experimental group than in the control group (t=12.40, p<.001). Conclusion: Continuous application of the FACP among child care teachers is expected to minimize the harm caused by minor accidents at child care facilities. This program should be formally implemented on a consistent basis.

This paper proposes a new confidence measure for utterance verification with posterior probability approximation. The proposed method approximates probabilistic likelihoods by using Viterbi search characteristics and a clustered phoneme confusion matrix. Our measure consists of the weighted linear combination of acoustic and phonetic confidence scores. The proposed algorithm shows better performance even with the reduced computational complexity than those utilizing conventional confidence measures.

Purpose: The purpose of this study was to identify the influencing factors of mothers' confidence in their maternal role during the early postpartum period. Methods: Participants were 178 postpartum women who delivered at three specialized obstetrics and gynecology facilities and used the postpartum care facility in city B. Data were collected from February to April, 2012 using the scales of measurements of self-confidence in maternal role performance, maternal self-esteem, mother-to-infant attachment, social support, and childcare stress. Descriptive statistics, Pearson correlation coefficients, and stepwise multiple regression were used with the SPSS/WIN 18.0 program to analyze the data. Results: The scores for self-confidence in the maternal role showed significant negative correlations with the scores of childcare stress (r=-.40, p<.001). Parity and maternal attachment were significant predictors and accounted for 97.4% of the variance in self-confidence in the maternal role. Conclusion: To strengthen self-confidence in the maternal role of early postpartum mothers, prenatal class programs need to be complemented in order to reduce childcare stress and promote mother-to-infant attachment.

Computer vision techniques have been widely employed in automated construction management to enhance safety and prevent accidents at construction sites. However, previous research in the field of vision-based approaches has often overlooked small-sized construction tools. These tools present unique challenges in data collection due to their diverse shapes and sizes, as well as in improving model performance to accurately detect and classify them. To address these challenges, this study aimed to enhance the performance of vision-based classifiers for small-sized construction tools, including bucket, cord reel, hammer, and tacker, by leveraging synthetic images generated from a 3D virtual environment. Three classifiers were developed using the YOLOv8 algorithm, each differing in the composition of the training dataset: (i) 'Real-4000', trained on 4,000 authentic images collected through web crawling methods (1,000 images per object); (ii) 'Hybrid-4000', consisting of 2,000 authentic images and 2,000 synthetic images; and (iii) 'Hybrid-8000', incorporating 4,000 authentic images and 4,000 synthetic images. To validate the performance of the classifiers, 144 directly-captured images for each object were collected from real construction sites as the test dataset. The mean Average Precision at an IoU threshold of 0.5 (mAP_0.5) for the classifiers was 79.6%, 90.8%, and 94.8%, respectively, with the 'Hybrid-8000' model demonstrating the highest performance. Notably, for objects with significant shape variations, the use of synthetic images led to the enhanced performance of the vision-based classifiers. Moreover, the practical applicability of the proposed classifiers was validated through confidence scores, particularly between the 'Hybrid-4000' and 'Hybrid-8000' models. Statistical analysis using t-tests indicated that the performance of the 'Hybrid-4000' model would either matched or exceeded that of the 'Hybrid-8000'model based on confidence scores. Thus, employing the 'Hybrid-4000' model may be preferable in terms of data collection efficiency and processing time, contributing to enhanced safety and real-time automation and robotics in construction practices.

Purpose: To investigate the effect of infant massage on stress, immune function and self-confidence in postpartum mothers. Method: From September, 2003 to February, 2004, 65 women who had delivered babies and were enrolled in the postpartum clinic were assigned to the experimental group or control group. In the experimental group, infant massage was given for 20 minute sessions twice a day from 4 days to 14 days after delivery. The instruments were Parental Stress Index, serum cortisol levels, WBCs, lymphocytes, and Self Confidence Scale. Results: Stress scores, WBCs and lymphocytes showed significant differences by the time, but there weren't significant differences according to the group and interactions between the group and the time. Cortisol and self-confidence scores showed significant differences by the time and the group. Conclusions: Applying massage to their newborn baby influenced cortisol levels of postpartum mothers. Therefore stress, cortisol, and immune functions in postpartum mothers should be generally screened and follow up studies are needed for the effective application of massage in postpartum mothers.
