The purpose of the study was to investigate the effects of early childhood teachers' professionalism and teaching efficacy on their teacher-child interaction. A total of 761 early childhood teachers working at childcare centers and kindergartens in South Korea were selected as the participants for the study. The study variables were measured using survey questionnaires. Pearson's correlation analyses and regression analyses along with Sobel test were conducted. The results demonstrated that early childhood teachers' teaching efficacy had a significant mediation effect on the relationship between their professionalism and teacher-child interaction. The results suggest the need to support early childhood teachers' recognition and development of professionalism as well as teaching efficacy that result in positive teacher-child interaction.

Purpose : This study identified the factors affecting the clinical competence of emergency unit nurses caring for foreign patients. Methods : This study utilized a descriptive correlation design. Participants were 112 emergency unit nurses working in different hospitals designated as the government's emergency medical centers and agencies in 2018. The collected data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple linear regression analysis. Results : Subjects' clinical competence showed positive relationships with cultural competency (r=.45, p<.001) and intercultural communication (r=.53, p<.001). Factors that affect the clinical competence of subjects showed intercultural communication (β=0.38, p=.001). Conclusion : It is necessary to develop programs to improve intercultural communication, factors that influence clinical competence of emergency unit nurses, and apply them to practical fields.

In the case of incumbent training, unlike training for the unemployed, it is difficult to show the results of training. In this study, factors affecting the performance of vocational competency development training were selected and the main factors were derived. Data were collected through Focus Group Interview(FGI), and regression analysis was performed through factor analysis and reliability analysis. As a result, empathy, training participation type, reliability, working experience, and training operation type were derived as factors affecting job satisfaction. did. Confidence and training participation patterns were derived as factors affecting training satisfaction, and the results showed that the larger the variable, the more positive it was. Therefore, as factors affecting the vocational competency development training performance, there are empathy, training participation type, reliability, work experience, training operation type, certainty, and training participation type. It was confirmed that the results had an effect.

This paper presents floating absorber for safety at transient (FAST) which is a passive safety device for sodium-cooled fast reactors with a positive coolant temperature coefficient. Working principle of the FAST makes it possible to insert negative reactivity passively in case of temperature rise or voiding of coolant. Behaviors of the FAST in conventional oxide fuel-loaded and metallic fuel-loaded SFRs are investigated assuming anticipated transients without scram (ATWS) scenarios. Unprotected loss of flow (ULOF), unprotected loss of heat sink (ULOHS), unprotected transient overpower (UTOP) and unprotected chilled inlet temperature (UCIT) scenarios are simulated at end of life (EOL) conditions of the oxide and the metallic SFR cores, and performance of the FAST to improve the reactor safety is analyzed in terms of reactivity feedback components, reactor power and maximum temperatures of fuel and coolant. It is shown that FAST is able to improve the safety margin of conventional burner-type SFRs during ULOF, ULOHS, UTOP and UCIT.

This study aims to find the better working environment for the start-ups by tracking and analyzing the data from the firms that have occupied in the business incubator and also the firm that already left the business incubator. To do so, a total of the sixteen firms were responded and ten out of the sixteen were the firm that have occupied in the business incubator and the rest six were the firm already left. Based on the response, the positive things that they earned from the business incubator were renting an office or higher levels of technical skills; however, the negative things were low operating profit can be negative. The results of this study can contribute to the development of the business incubator for the future. The further study regarding satisfaction survey might help to build more creative and constructive environment for the business incubator.

Purpose: This study aimed to determine the effects of grit, nursing work environment, and job esteem on the intent to stay among military hospital nurses. Methods: This study employed a descriptive cross-sectional design. Data were collected from February 7 to 18, 2022 from 232 nurses working at four military hospitals under the Armed Forces Medical Command. The analysis was conducted using the SPSS/WIN 26.0 program, and descriptive statistics, t-test, ANOVA, Pearson coefficient correlations, and multiple regression analysis were performed. Results: Factors affecting the intent to stay included job esteem (β=.44, p<.001), total clinical experience of more than 10 years (β=.24, p=.001), and nursing work environment (β=.17, p=.009). Conclusion: The results can be used to ensure personnel quality at military medical institutions and can contribute to improving patient safety and medical services. Further, nursing managers need to formulate and implement strategies to foster a positive nursing work environment.

Objectives: This study aimed to confirm the relationship between occupational safety and health information and self-rated health among precarious workers. Methods: A cross-sectional explanatory study design was conducted using data from the Korea Occupational Safety and Health Agency's 6th Korean Working Conditions Survey. The participants were 1,569 precarious workers living in South Korea. Descriptive statistics, t-test, ANOVA, Pearson correlation analysis, and hierarchical regression were used for data analyses by SPSS (version 25.0). Results: As a result of the study, occupational safety and health information had a significant positive effect on the self-rated health of precarious workers. The results suggest that occupational safety and health information contributes to the self-rated health of precarious workers. Conclusions: Therefore, it is suggested that policies should be developed to improve occupational safety and health information in workplaces. In addition, strategies should be developed to promote the usefulness of occupational safety and health information to precarious workers.

The purpose of the study was to examine the effects of early childhood teachers' professional development and Grit on their teacher-child interactions. The subjects were 363 early childhood teachers working at kindergartens or childcare centers of South Korea. We used self-reporting survey questionnaires to measure the major variables and utilized the SPSS 28.0 Program to analyze the collected data. Cronbach's alphas were calculated and the descriptive statistical analyses were conducted. To investigate the research questions, Pearson's correlation analysis and multiple regression analysis were done. As results, the higher early childhood teachers' professional development and Grit were, the higher their teacher-child interactions were. Early childhood teachers' professional development and Grit were found to have positive effects on their teacher-child interactions, which showed that professional development and Grit would predict the quality of interactions between teacher and young children. Based on these results, we suggest the importance of early childhood teachers' professional development and Grit so that they practice excellent interactions with young children in order to support development and learning through play.
