The purpose of this study was to examine the relationships between child's self-regulation and stress according to child's sex. The subjects for this study were 380 children of 5-6th grade selected from elementary schools in Busan. Lee, Soon-Kyu's questionnaires(1994) on child's self-regulation and Han, Mi-Hyun's questionnaires(1996) on child's stress were used. Statistical techniques such as Manova, Pearson's correlation, multiple regression, canonical were used. The resets were as follows : (1) According to sex, there were significant differences in child's self-regulation and stress. The girls showed more self-regulation and higher friend-related stress than the boys. The boys showed higher parent-related stress than the girls. (2) Relationships between child's self-regulation and stress showed as follows : The boys who used more impulsive-control perceived lower friend-related stress, lower school-related stress, lower teacher-related stress, and lower surroundings-related stress. And the boys who used more behavioral-control perceived lower school-related stress, lower teacher-related stress, and lower surroundings-related stress. (3) The predicted variable for boy's friend-related stress was impulsive-control. The predicted variables for boy's school-related stress, teacher-related stress and surroundings-related stress were impulsive-control and behavioral-control. (4) Among three dimensions of self-regulation for boy, the effective variables were impulsive-control and behavioral-control. And among six dimensions of stress were surroundings-related stress, school-related stress and friend-related stress. Implications of this study were discussed in terms of child's self-regulation and stress.

Osteoporosis is a major health problem confronting middle-aged women today. Enhancing calcium intake in early adulthood can increase the rate of calcium gain in bone. In this study, we investigated the association of bone health-related nutritional knowledge levels with calcium-related dietary behavior and nutrition education among women. Data were collected using questionnaires from 347 women aged 20~30 residing in Gyeonggi-do. Subjects were categorized into two groups according to their bone health-related nutritional knowledge (high or low-knowledge group). Knowledge related to bone health and calcium, and dietary habits was assessed, and the preference for and intake frequency of calcium-rich food were collected and analyzed using food frequency questionnaires. The high-knowledge group showed a significantly higher rate of nutritional education experience (33.9%) when compared with the low-knowledge group (18.9%). Not only were the perceptions regarding milk and dairy products more positive in the high-knowledge group (P<0.05), but the intake frequency of calcium-rich foods, such as tofu, soybean, and anchovies, was also higher in this group compared to the low-knowledge group (P<0.05). Overall, the preference for all calcium-rich foods was positively correlated to their intake frequency (P<0.05). Nutrition education experience and the recognition of the need for such education were positively correlated with the bone health-related nutrition knowledge score (P<0.05). In conclusion, bone health-related nutritional knowledge can affect calcium-related dietary behavior and increase the intake of calcium-rich food of 20~30-year-old women and this can contribute to the prevention of osteoporosis. To improve bone health-related nutritional knowledge among young women, it may be important to provide nutrition education.

Background: Recently, irregular working hours have become controversial issues in Korea. The health impact of irregular working hours on the work-related musculoskeletal pain (MSP) is scarcely researched before. We sought to investigate the association between irregular working hours and work-related MSP among South Korean workers. Methods: This study used data from the sixth Korean Working Conditions Survey in 2020. The prevalence of work-related MSP was analyzed using the χ² test. A multiple logistic regression analysis was conducted to assess the association between irregular working hours and work-related MSP. We conducted stratified analysis by gender, weekly working hours, and workers' control over their working hours. We calculated the adjusted odds ratios (ORs) of work-related MSP for irregular working hours combined with weekly working hours. Results: The OR for work-related MSP was significantly higher in the population with irregular working hours than in the population with regular working hours (OR: 1.43, 95% confidence interval [CI]: 1.29-1.58). Irregular and long (> 52 hours/week) working hours have the highest risk of work-related MSP in both genders (in men, OR: 3.48 [95% CI: 2.53-4.78]; in women, OR: 2.41 [95% CI: 1.46-4.00]). Conclusions: Irregular working hours were associated with work-related MSP in Korea. The association was magnified with long working hours. Reform of the Korean Labor Standards Act leading to increase irregular working hours may induce adverse health outcome.

Policy of for-profit hospitals permission has provoked debate on how to enhance health care system and medical service industry. The government says that for-profit hospitals could help improve the quality of medical care and develop medical tourism. On the other hand, Medical care related NGO insist that for-profit hospitals will not fix the existing medical problems in Korea, only create new ones. Recently, a type of for-profit hospitals emerged in dentistry and caused much trouble. Accordingly, We try to carefully look at for-profit hospitals related policy and debate.

This study examined the direct and indirect influences of adolescents' self-esteem, impulsiveness, departments of school, perceived communications with mothers and peer support on internet-related delinquencies. The study consisted of 555 second-year students from a vocational, academic oriented girl's high schools that were located in Busan. Data analysis was made through Two-Way ANOVA, Pearson's Correlation, Multiple Regression, and Path Analysis by using SPSS WIN 10.0. The results of this study is described as follows. First, internet-related delinquencies were committed by male students more than by female students. Second, problematic communications with mothers was most directly influenced by internet-related delinquencies of high school students of both sexes and was indirectly influenced by self-esteem and impulsiveness. Third, impulsiveness was directly influenced by internet-related delinquencies in both male and female students. In male students, their school departments indirectly influenced internet-related delinquencies by way of open communication with mothers, peer support, self-esteem, and impulsiveness. In female students, school departments directly influenced on internet-related delinquencies and indirectly by way of peer support, self-esteem and impulsiveness. Internet-related delinquencies by male and female students were not directly influenced by peer support and self-esteem. But peer support did have indirect effects on internet-related delinquencies by way of self-esteem and impulsiveness, and self-esteem also had indirect effects by way of impulsiveness.

This study examined the direct and indirect influences of parental behavioral control on adolescents' school related adjustment by exploring pathways between parental behavioral control, adolescents' anxiety, and school related adjustment. Participants were composed of 319 high school 1st graders (153 male and 165 female students) from the Seoul area. They completed questionnaires on parental behavioral control, adolescents' anxiety, and adolescents' school related adjustment. The collected data were analyzed using Pearson's correlation coefficients, Factor Analysis, and Structural Equation Modeling. It was adapted to SPSS version 19.0 and Amos version 21.0 for Windows. The results indicated that adolescents' anxiety partially mediated the association of parental behavioral control and adolescents' school related adjustment. More concretely, direct effect of adolescents' anxiety on adolescents' school related adjustment were slightly greater than the direct/indirect effects of parental behavioral control on adolescents' school related adjustment. The effect of adolescents' anxiety on adolescents' school related adjustment was the greatest among all associations between research variables. The findings of this study have implications for research and practice that highlights the important considerations for proper parental behavioral control and reducing adolescents' anxiety that should be emphasized to improve adolescents' school related adjustment. We believe that improved parental behavioral control needs to be emphasized when designing prevention and parent intervention education programs for adolescents' psychological problem and school related adjustment.

The purpose of this study was to investigate the effect of perceived parental behavior and children’s coping behaviors with parent-related problems on parent-related stress. The subjects were 234 children composed of 115 3rd-graders and 119 6th-graders elected from three elementary schools in Seoul(121 males and 113 females). Statistical techniques were means, Percentages, Scheffe test, ANOVA and Multiple Regressions. The major findings of this study were as follows : 1) There was a significant difference in parent-related stress with respect to perceived parental behavior and coping behaviors of childrens such as passive, avoidant, and aggressive coping. Perceived parental behavior and aggressive coping behavior showed significant interaction effects. When children perceived parental behavior as being less suppotive and children more aggressively coped with parent-related problems, parent-rotated stress increased in level. 2) Among perceived parental behavior and pasive, avoid, aggressive coping behavior, perceived parental behavior and passive coping behavior were significant predictors of parent-related stress. Perceived parental behavior was much more predictor of parent-related stress than the passive coping behavior.

This study investigated the relationship of demographic and psychological variables with job and family-related stress among 293 employed wives. We found that age, job types, working in weekend, and family cohesion significantly contributed to the explanation of job-related stress. We also found that job types, working in weekend, family adaptation, family cohesion, and employment motivation significantly contributed to explaining the variation of family-related stress. Job-related stress was more explained by demographic variables than psychological ones, whereas family-related stress was more explained by psychological variables than demographic ones. Practical implications of the current findings were discussed.

This study investigated gender differences in science-related attitude and to analyze association patterns among social factors affecting the differences. The relationships between student's science-related attitude and four variables - schools, teachers, friends and parents influencing the attitude were analysed. The questionnaire, which identifies whether the four variables influence students' science-related attitudes, were specially constructed and simultaneously administered with test of science-related attitudes (TOSRA) to 603 subjects: junior high, and high school students. Both boys and girls were not significantly different at TOSRA scores; however, by multiple regression analysis, the boys' TOSRA scores were influenced by the variable of parents and the girls' scores were influenced by teachers and friends. Social factors evoking gender differences on science-related attitude do not influence equally at everyday life of boys and girls. As the gender differences in science-related attitude decrease, perceptual changes of parents and teachers, the two most influential factors to make the differences should be important to drag females in science-related work as a desired occupation for women.
