This study attempt to test not only the impact of leadership(second-level supervisor's ethical leadership, immediate supervisor's transformational leadership) on followers' proactive behavior, but also the effect second-level supervisor's ethical leadership on leader's transformational leadership(i.e. TL). In particular, immediate supervisor's TL is explored as a mediating variable in the relationship between second-level supervisor's ethical leadership and followers' proactive behavior. The summary of the hierarchical regression analyses results was as follows: First, the paper showed that second-level supervisor's moral behavior was positively related to immediate supervisor's TL. But behavioral integrity and consistency across contexts was not found to play a unique role in predicting immediate supervisor's TL. Second, second-level supervisor's moral behavior was a positive impact on employee' taking charge behavior and helping behavior. and behavioral integrity was a positive impact on employee' taking charge behavior. But consistency across contexts was not found to play a unique role in predicting proactive behavior. Third, immediate supervisor's TL was a positive impact on employee' taking charge behavior and helping behavior. Finally, the effects of second-level supervisor's moral behavior on employee' proactive behavior were mediated by immediate supervisor's TL. Theoretical and practical implications of our findings as well as directions for future research are provided.

In this paper, we apply data mining techniques and machine learning algorithms using R software, which is used to predict, here we applied a regression model to test some factor on the dataset for which we assumed that it effects student performance. Model was built on an existing dataset which contains many factors and the final grades. The factors tested are the attention to higher education, absences, study time, parent's education level, parent's jobs, and the number of failures in the past. The result shows that only study time and absences can affect the students' performance. Prediction of student academic performance helps instructors develop a good understanding of how well or how poorly the students in their classes will perform, so instructors can take proactive measures to improve student learning. This paper also focuses on how the prediction algorithm can be used to identify the most important attributes in a student's data.

Purpose: This study investigated the correlations among resilience, the awareness of patient safety management, proactive behavior, and the performance of standard precautions among nurses working in the emergency department. Additionally, it aimed to identify the factors influencing the performance of standard precautions. Methods: Data were collected through a descriptive survey conducted between June 10 and July 9, 2023. The participants included 208 nurses working in the emergency department in Korea. The collected data were analyzed using SPSS/WINdows software version 29.0, based on the frequency, percentage, mean, standard deviation, t-test, one-way analysis of variance, Scheffé test, Pearson's correlation coefficients, and multiple regression. Results: The analysis based on the participants' general characteristics showed that performance of standard precautions varied significantly according to age (t=2.10, p=.036), size of the emergency department (F=7.46, p<.001), average number of patients treated per day while working in the past month (t=-3.88, p<.001) and standard precautions training experience (t=2.16, p=.032). The main factors influencing the performance of standard precautions among nurses working in the emergency department are awareness of patient safety management (β=.62, p<.001), resilience (β=.18, p=.042), and age (β=-.15, p=.007), with a total explanatory power of approximately 46.0%. Conclusion: It is necessary to establish programs and an effective education system to increase resilience and awareness in patient safety management to improve the performance of standard precautions among nurses working in the emergency department.

Subjects were 151 early childhood teachers in Seoul and Chungcheungnam-do. The collected data were analyzed using simple regression, hierarchical multiple regression and the Sobel test. The main results of this study were as follows. First, teachers' playfulness and teachers'positive play beliefs had a positive influence on their proactive, positive reactive strategies of problem behaviors. On the other hand, teachers' positive play beliefs had a negative influence on their negative reactive strategies of problem behaviors. Second, teachers' playfulness and teachers'positive play beliefs had a positive influence on their teaching efficacy on play. Finally, the effects of teachers' playfulness on their proactive, positive reactive strategies of problem behaviors of preschoolers were totally mediated by their teaching efficacy on play.

Purpose: The purpose of this study was to identify the influencing factors on turnover intention of nurses in long-term care hospitals. Methods: Data were collected from 210 nurses in 11 long-term care hospitals in B city. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and Stepwise multiple regression. Results: Turnover intention was significantly correlated with emotional labor(r=.35, p<.001) and job involvement (r=-.38, p<.001). In a multiple regression, emotional labor (${\beta}=.31$, p<.001), age (${\beta}=-.27$, p<.001), job satisfaction (${\beta}=.24$, p<.001), job involvement (${\beta}=-.23$, p<.001), and number of patients assigned(${\beta}=.14$, p=.009) were associated with turnover intention. These factors attributed to 41.2% of the total variance in turnover intention. Conclusion: Considering the results of this study, proactive educational and/or human resource management interventions need to be developed especially for those younger nurses in order to reduce emotional labor as well as to promote job satisfaction and job involvement of nurses in long-term care hospitals.

Intelligent machines respond to external environments on the basis of decisions that are made by sensing the changes in the environment and analyzing the obtained information. This study focuses on the construction of a knowledge base which enables decision making with that information. Approximately 70% of all errors that occur in machine tools are caused by thermal error. In order to proactive deal with these errors, a system which measures the temperature of each part and predicts and compensates the displacement of each axis has been developed. The system was built in an open type controller to enable machine tools to measure temperature changes and compensate the displacement. The construction of a machining knowledge base is important for the implementation of intelligent machine tools, and is expected to be applicable to the network based intelligent machine tools which look set to appear sooner or later.

This study examined the factors that affect the turnover intention of newly graduated nurses. The basic data was utilized for developing a personnel resource maintenance program for newly graduated nurses. New nurses working at a general hospital in City D were surveyed from May 2016 to April 2018. The questionnaires completed by 232 volunteers were analyzed using the IBM SPSS 21.0 program, and the descriptive statistical analyses included t-tests, ANOVA, Scheffe test, Pearson's correlation coefficient, and multiple regression analysis. Among the general characteristics of new nurses, their workload displayed significant differences in proactive behavior, organizational commitment, social support, and the turnover intention. There was a negative correlation between organizational commitment, employer support, peer support, and the turnover intention. The influential factors were organizational commitment and workload, and the explanatory power for turnover intention was 36.1%. Higher organizational commitment, along with appropriate workload, led to a lower turnover intention. Therefore, appropriate work allocation through work analysis is necessary to lower the nurses' turnover intention. Developing a program that can increase proactive behavior and implementing various intervention strategies can increase the participation of newly graduated nurses when establishing and implementing appropriate hospital policies.

This research was conducted in order to find out the effects of boys' self-control, their parents' behaviors and marital conflict on boys' aggression. Subtypes of aggression in the present research consist of dimensions of the functions and forms (proactive-overt, proactive-relational, reactive-overt, reactive-relational). The participants of this study were 237 boys in the fifth and sixth grades in elementary schools located in Seoul and Gyeonggi province. The questionnaires were derived and modified from Lee Hong (2009) for boys' aggression, from Ju So Young and Lee Yang Hee (2008) for boys' self-control, from Jun Joo Ram (2008) and Heo Seung Yeon (2009) for maternal behaviors and from Kang Na Jung (2008) for marital conflict. In order to grasp the general characteristics of the participants, frequency and descriptive statistics were used. Also, Pearson's correlation was applied to the relationships amomg boys' self-control, marital behaviors and marital conflict on boys' aggression. Lastly, the variables that can predict boys' aggression were analyzed through multiple regression analysis by SPSS 19.0. The major results of this study were as follows. This research showed that this model fit well for boys. To summarize the important results, what is interesting in the present study is the effect of the mother's role in rearing their sons. It was found that mothers' criticism, negative behaviors, and excessive interference can cause boys' high level of aggressiveness. Also, having parents who fight frequently was strongly associated with boys' relational aggression. An interesting finding is that the mother's support influenced boys' reactive-overt aggression. Lastly, boys' self-control was highly associated with boys' proactive-relational aggression. This research may contribute to understanding boys' aggression' subtypes. To that end, the current results suggest that the dimensions of the functions and forms may be a useful tool in an effort to inform developmental theory and intervention. Also, this research may provide guidance for the resolution of problems caused by boys' aggression. Lastly, it was found that self- control training and parental education programs might prove beneficial for helping aggressive boys to overcome their aggressive impulses.
