This study examines different individual and environmental factors that affect children's self-control. For an analysis, locus of control, perceived competence, and achievement motivation were all included in individual variables. For family variables, mothers' parenting and patents' marriage conflict were examined. For classroom psycho-social environment, teacher support, peer relationship, class involvement, and teachers' supervision were used. The sample consisted of 548 fifth and sixth grade children. Statistics and methods used for the data analysis were Cronbach's alpha, frequency, percentage, Pearson's correlation, and Hierarchical Regression. Several major results were found from the analysis: First, locus of control, perceived competence, and achievement motivation had a positive correlation with children's self-control. Second, mothers' affective parenting had a positive correlation with children's self-control. However, mothers' controlling parenting and parents' marriage conflict had a negative correlation with it. Third, teacher support, peer relationship, and class involvement had a positive correlation with children's self-control. In addition, teacher supervision had a positive correlation with girls' self-control. Fourth, class involvement, locus of control, and academic competence were important variables predicting boys' self-control. On the other hand, Class involvement, achievement motivation, academic competence, teacher's supervision, and mothers' controlling parenting were important variables predicting girl's self-control.

This is an investigative study to identify the degree of post-traumatic stress and anxiety of nurses in relation to the COVID-19 pandemic, and to analyze the relationship with the nurse's belief in behavior and control that affects nursing intentions to determine their impact on the belief in behavior. The subjects of this study were nurses with experience of directly nursing COVID-19 patients at medical institutions located in Gyeonggi-do. The SPSS 22.0 version was used for the descriptive analysis, independent t-test, one-way ANOVA, Pearson's correlation coefficients and multiple regression. Post-traumatic stress of the participants in this study was found to be 24.20±20.58, anxiety 48.31±6.61, behavior beliefs -1.00±17.12, and control beliefs 3.41±11.66. According to this study, the belief in conduct is negatively correlated with post-traumatic stress (r=-4.71, p<).001) and showed a significant negative correlation with anxiety (r=-2.248, p<.05). There was no significant correlation with control beliefs (p>.05). Based on the results of this study, it is proposed to develop an appropriate psychological arbitration program for mediating post-traumatic stress in order to promote the nurse's behavior beliefs.

Objective : This study aims to verify the validity and reliability of the Korean version of the Sensory Processing and Self-Regulation Checklist (SPSRC) for children with and without autism spectrum disorder. Methods : The Pearson product-moment correlation coefficient was calculated using Short Sensory Profile (SSP) to verify concurrent validity. Construct validity was verified by comparing the sensory processing ability and self-regulation ability of the two groups. Cronbach's α was calculated in the case of internal consistency for reliability verification, and the test-retest reliability was verified through the Pearson correlation coefficient. Results : Based on the verification of the concurrent validity, the Korean version of SPSRC and SSP showed a statistically significant correlation (p < 0.01). The construct validity was found to have a statistically significant difference between the two groups in the area and sub-items of the Korean version of SPSRC (p < 0.001). For the internal consistency, Cronbach's α ranged from 0.700 to 0.975. The test-retest reliability showed that the correlation coefficient ranged from 0.937 to 0.997. Conclusion : The Korean version of SPSRC was confirmed to be an evaluation tool with high validity and reliability. It is expected to be used as an evaluation tool for planning treatment goals in clinical trials and as a meaningful basis for future research.

The purpose of this study was to examine the reliability and validity of the K-CPQ in 299 children with developmental disorder and non-disabled children to prove their level of participation in Korean children with developmental disabilities. In order to verify the reliability of the K-CPQ, Cronbach ${\alpha}$ was calculated and Pearson correlation analysis was used for test-retest reliability test. As a result, the internal consistency(${\alpha}=.81{\sim}.90$) in each area of K-CPQ was relatively high and the Pearson correlation coefficient (r=.807~.843) in the test-retest reliability test was significant in all areas(p<.01). It showed statistically significant difference in all areas(t=2.32~5.18) in comparison with the non-disabled children group in order to verify the discriminant validity of K-CPQ. For the criterion-related validity of the K-CPQ, Pearson correlation analysis of K-SMS and K-SFA shows statistically significant static correlation(r=.817, r=743) showed(p<.01). Through this study, K-CPQ has been confirmed as a reliable and reasonable assessment tool and we expect that diverse research by K-CPQ will provide appropriate interventions for children with disabilities.

Many countries around the world using ICT technologies have various technologies to keep pace with the 4th industrial revolution, and various algorithms and systems have been developed accordingly. Among them, many industries and researchers are investing in unmanned automation systems based on AI. At the time when new technology development and algorithms are developed, decision-making by big data analysis applied to AI systems must be equipped with more sophistication. We apply, Pearson's correlation analysis is applied to six independent variables to find out the job satisfaction that office workers feel according to their job characteristics. First, a correlation coefficient is obtained to find out the degree of correlation for each variable. Second, the presence or absence of correlation for each data is verified through hypothesis testing. Third, after visualization processing using the size of the correlation coefficient, the degree of correlation between data is investigated. Fourth, the degree of correlation between variables will be verified based on the correlation coefficient obtained through the experiment and the results of the hypothesis test

In this study, the exhaust characteristics of the diesel engine for the change of the mixing ratio of biodiesel fuel were quantitatively analyzed by using the numerical analysis method. As the fuel used in the experiment, the diesel and biodiesel(waste oil, soybean oil), the mixed fuel BD2(Diesel only), BD3, BD5, BD20, BD50 and BD100 were used. The injection pressure($p_{inj}$) was set to 400bar, 600bar, 800bar, 1000bar and 1200bar as the experimental variable. Also the concept of the standard deviation, Pearson's correlation coefficient and Spearman rank-order correlation coefficient based on the statistics was introduced in order to analyze the exhaust characteristics of the quantitative NOx and Soot according to the injection pressure and the mixing ratio variation of biodiesel blending fuel. It is considered that as a result of studies, for the waste oil, NOx and Soot can be simultaneously reduced through control of the mixing ratio at the regions of $p_{inj}=400bar$ and $p_{inj}=600bar$, and the Soot can be reduced without affecting on the emission of NOx at more than $p_{inj}=800bar$. For the soybean oil, NOx and Soot can be simultaneously reduced at $p_{inj}=400bar$ and the Soot can be reduced without affecting on the emission of NOx at $p_{inj}=600bar$.
