In this study, we developed a test tool to measure the computational thinking ability of middle school students and investigated their computational thinking power using the tool. The test tool used exploratory factor analysis to examine the computational thinking scales of Korkmaz et al. (2017) and derive suitable factors and questions for middle school students in Korea. The developed test tool was applied to 492 middle school students to analyze differences in computational thinking ability according to gender, grade, programming experience, type of programming language, and interest. According to the study, male Korean middle school students had higher computing power than females. In addition, students who had programming experience or used text-based rather than block-based programming languages demonstrated higher computational thinking. There was no significant difference in the computational thinking of middle school students according to grade, and the level of interest in artificial intelligence only had a slight influence on computational thinking.

Purpose: The purpose of this study was to investigate predictors of behavior problems of military children in elementary school. Methods: Participants were 195 military children who were attending D-elementary school in C-city. Data were collected from July 8 to July 10, 2013, using self-report questionnaires which included Han's Externalized Behavior Problems Scale, Lee's Parent's Rearing Attitude Scale, and Hong's Friend/Teacher Support Appraisal Scale. Data analysis was performed using the SPSS/WIN 18.0 program, which included the t-test, the one-way ANOVA, Pearson correlation coefficients, and the multiple liner regression analysis. Results: The mean score of the subjects' behavior problem was 1.47/5.0 points. The degree of the score is similar to or slightly lower than that of ordinary children. There were statistically significant differences in behavior problems according to gender, grade, birth order and economic status. Behavior problems have a negative correlation with parent's rearing attitude, parent-child relationship, teacher's support, and friend's support. Influencing factors of behavior problems were teacher's support, father-child relationship, and mother's rearing attitude, which explained 20.6% of the variance. Conclusion: The finding of this study suggests there is a need to increase teacher's support for elementary students and to educate parents to improve their parenting skills by developing proper school health programs.

Introduction: The objective of the present study was to investigate bedtime, rise time and time-in-bed of Korean college students, separately on weekday and on weekend and to compare them. In addition, this study also aimed to evaluate the influence of gender, age and grade on the above sleep parmeters in Korean college students. Methods: Information regarding bedtime and rise time, separately on weekday and on weekend, of Korean college students were obtained by self-administered questionnaire. Questionnaires of 1,825 students (1,416 females and 409 males, age 18-30；mean age $21.1{\pm}2.2$) were used for statistical analyses. Results: Korean college students retired to bed 50 minutes later (00：49 on weekday；01：40 on weekend；t=39.67, p<0.001), rose 1 hour 58 minutes later (07：52 on weekday；09：50 on weekend；t=39.46, p<0.001), and slept 1 hour 8 minutes longer (t=13.33, p<0.001) on weekend. Compared to male students, female students had earlier rise time (t=8.96, p<0.01；t=3.89, p<0.01) and earlier bedtime both on weekday and weekend (t=7.10, p<0.01；t=6.04, p<0.01), and shorter time-in-bed on weekday (t=1.99, p<0.01). In addition, rise time delay and time-in-bed increase on weekend were more prominent in female students than in male students (t=3.41, p<0.01; t=3.68, p<0.01). Grade was correlated with bedtime and rise time on weekday (${\beta}=0.1022$, p<0.01；${\beta}=0.1009$, p<0.01), bedtime and time-in-bed on weekend (${\beta}=0.1096$, p<0.01；${\beta}=-0.0990$, p<0.01), and differences between week-day and weekend of the rise time and the time-in-bed (${\beta}=-0.0906$, p<0.01；${\beta}=-0.1115$, p=0.02). Conclusions: In this study, Korean college students had earlier bedtime/rise time and shorter time-in-bed on weekday than on weekend. These findings suggest that weekday sleep-wake schedule of Korean college students may be advanced relative to their biological sleep-wake cycle and that this discrepancy may be associated with weekday sleep deprivation. In addition, differences of sleep patterns between weekday and weekend were more prominent in female students and students with lower grade. Therefore, discrepancy between weekday sleep-wake schedule and biological sleep-wake cycle, as well as weekday sleep deprivation, might be more serious in female or lower-grade students.

This study compared the individual, family, environmental factors, and subjective sleep sufficiency according to gender among Korean adolescents and to examine relevance among the individual, family, environmental factors, and subjective sleep sufficiency. The subjects were 65,528 Korean adolescents(male: 33,803, female: 31,725), who were derived from the 12th Korea Youth Risk Behavior Web-based Survey 2016 in South Korea. As a result, the prevalence of the subjective sleep sufficiency in this study was 33.4% male and 19.5% female. The subjective sleep sufficiency was affected by the depression experience, suicidal ideation, school achievement, feeling of stress, feeling of happiness, subjective health status, alcohol experience, smoking experience, substance experience, allergic rhinitis, and atopic dermatitis in individual factors; economic status, educational level of parents and living arrangement in family factors; school grade, school type and emotional support in environmental factors in both males and females. In individual factors, breakfast eating and asthma affected the male's subjective sleep sufficiency and physical activity affected the female's. The mental health of the individual factors was the most influential factor in adolescent's subjective sleep sufficiency. Therefore, nursing intervention to improve Korean adolescent's subjective sleep sufficiency should be applied considering gender differences.

This study aims to evaluate the satisfaction of students with a block system and it's effect on preparing students for a culinary career in the future. Summing up the outcomes of this study, male students reported higher levels of satisfaction than female students not only regarding a block system $perse$ (significant level 0.05) but with regards to career preparation as well (level 0.01). According to the choice variations disclosed by this study, a strong correlation exists with each of the p-values 0.000. Additionally, satisfaction with a block system appears to be strongly related to how well it is perceived to prepare students for future jobs with a RSQ = 0.840. Summing up the study's conclusions on gender effects, satisfaction with a block system is higher for males than females due to its being physically harder to take for female than for male students. Also, student grades have no correlation with satisfaction with a block system while they show significant differences in future job will. Freshmen (first year students) displayed the strongest level of satisfaction regarding future career preparation while seniors (fourth year students) the lowest. According to these results, we can posit a theory; gender and study years have an effect on the satisfaction with a block educational program and perceived value of career preparation. Therefore, culinary instructors and planners should consider this study's results to improve student satisfaction and future job preparedness.
