This study was carried out to evaluate the relations between sociodemographic, work-related factors and health related behaviors in a group of 1,042 workers in Taejeon and Chungnam area. The results were as followings: The older workers took more irregularly meals, more cigarette and more alcohol than the younger. Men had more appropriate sleeping time, more regular exercise than women, but more frequent alcohol consumption and cigarette smoking. The married had more regular sleeping habit than the unmarried. The group of married were smoking more and obese. In view of monthly income which represent the socioeconomic state of workers, the group of more than 1 million won had more frequent alcohol ingestion, more heavier body weight than another group of less than 1 million won. Workers having their work hours exceed 9 hours had inappropriate sleep duration, and shift workers took more irregularly meals. The group having poor self-rated health status showed more regular diet, exercise and overweight. Workers recently experienced chronic illness were more overweight and lesser smokers. Above results showed that the health related behaviors were related to the sociodemographic characteristics and occupation-related characteristics. The study for relationship between variant factors affecting health behavior and disease or mortality is need and it should be emphasized that the publicity and education of health related behavior for industrial workers is necessary.

This study aims to provide basic evidence for establishing prevention programs of school' mental health by identifying the factors of middle and high school student's depression and suicidal ideation related to stress of peer-relationship. For this purpose, we analyzed the data of 6,924 (who Experienced stress related to peer-relationship) among the 2012 Korean Youth Health Risk Behavior Online Survey(8th). In demographic characteristics, subjective academic achievement affects depression in the case of girls. In health-related characteristics, medical treatment by violence, drinking experience, smoking experience have an effect on depression in the case of boys. Subjective health, drinking experience, smoking experience, drug experience are the factors affecting suicidal ideation both boys and girls. In order to promote mental health of youth, school-based prevention education complementing existing realistic problems needs to be implemented.

The main purpose of this study was to examine the mediating roles of mothers' psychological well-being and support/control in the relationship between maternal child-related stress and adolescents' school adjustment. Participants were 389 3rd grade middle school students and their mothers. Mothers completed questionnaires about child-related stress and psychological well-being. Adolescents completed scales of maternal controlling/supportive parenting and school adjustment. Results indicated that a direct effect of mothers' child-related stress on adolescents' school adjustment was not significant. However, mothers' psychological well-being and support/control mediated the relations between child-related stress and adolescents' school adjustment. A higher level of child-related stress in mothers was associated with a lower level of psychological well-being, followed by a lower level of adolescents' school adjustment. Mothers who reported a higher level of child-related stress tended to be less supportive and more controlling, which led to a lower level of school adjustment. These findings suggest the need for considering both maternal characteristics and parenting in explaining adolescents' school adjustment.

This study investigated the academic achievement of science and high school students according to the characteristics of R&E activities in mathematics and science. In addition, based on the survey results, the correlation between R&E activity characteristics and mathematics and science academic achievement was studied through correlation analysis and factor analysis between subjects. There was a difference in academic achievement in mathematics and science according to the characteristics of the R&E activity area, and the experience of R&E activity was found to be closely related to the academic achievement of related subjects. Depending on the area of R&E activity, mathematical and scientific academic achievement was found to be two factors: mathematical logic and natural understanding. Natural understanding factors significantly influenced students' academic achievement in mathematics, physics, and life sciences, and mathematical logic factors significantly influenced the academic achievement of students in chemistry and earth science subjects. In particular, mathematical logic ability was concentrated in excellent physics class students, and natural understanding ability was concentrated in excellent life science class students. Since the characteristics of the R & E activity area greatly influence the academic achievement of mathematics and science, it will significantly contribute to the selection and operation of the R & E activity area of science high school students.

Objectives: The purpose of this study is to identify the general characteristics of manufacturing workplaces and the characteristics of safety and health organizations, and to determine the impact of safety and health-related communication within these organizations mediated by supervisory safety and health management personnel. Methods: This study is based on the Korea Occupational Safety and Health Agency's 2018 Occupational Safety and Health data targeting 1,486 manufacturing sites. Data were analyzed using descriptive statistics, t-test and ANOVA, and mediator variable regression analysis using SPSS 25.0. Results: The average score on communication levels related to safety and health was 11.20 out of 15. The average score of the safety and health management level was 31.04 out of 40. As a result of mediation regression analysis, it was found that safety and health-related communication had an effect on the safety and health management level (𝛽=0.434), and the number of safety and health supervisors was found to mediate the effect of this variable (𝛽=0.069). Conclusions: The level of safety and health-related communication affects the level of health and safety management, and the number of supervisors mediates this influence. Therefore, the role of the supervisor is important in safety and health communication. It is expected that the level of safety and health management can be improved through management and supervisors.

In this paper, we posit that time-related effects (i.e., the importance of saving time) on patronage preference for shopping online will be moderated by consumer characteristics. To explore these moderating effects, we empirically examine the moderating roles of consumer characteristics on the respective effects of shopping-time-saved and delivery on online purchase preference. On the basis of analyses performed on data gleaned from an Internet-based survey, this study demonstrate that time effects related to both shopping-time-saved and delivery on online purchase preference are more pronounced for consumers who are male, young, and more starved for time. In addition, the effect of delivery time on online patronage preference is amplified by disposable income, but attenuated by online shopping experience. Through our analyses, we also find that Japanese consumers value delivery time to a greater degree than Chinese and American consumers do.

Voltage-dependent transmittance characteristics associated with various cell parameters have been studied in-plane switching liquid crystal display when both common and pixel electrodes are transparent. When both electrodes are opaque, the transmittance is related to only the distance (I) between electrodes. However, where transparent electrode is used, it is influenced not only the 1but also an electrode width (w) and rubbing angle. In addition, these factors are related to operating voltage which shows maximal transmittance. To maximize the light efficiency of the cell and obtain low operating voltage, the above-mentioned cell parameters need to be optimized.

Purpose: There is little known about teachers' self-efficacy in health teachers even though over 75% of Korean health teachers have offered school health education. The purpose of this study was to examine factors related to teachers' self-efficacy in Korean health teachers. Methods: Data were collected from school nurses from 474 schools such as 236 elementary schools, 140 middle schools and 98 high schools in Seoul with the stratified random sampling method. The associations among school characteristics, health teachers' characteristics, and teachers' self-efficacy were examined by ANOVA (Anlaysis of variable). To identify the possible predictors of teachers' self-efficacy, ANCOVA (Analysis of covariance) was performed. Results: Two factors, school stage (elementary, middle or high schools) and types of school (public or private school), were significantly related to teachers' self-efficacy. Teachers' self-efficacy of health teachers in elementary schools was significantly higher than that in middle and high schools. Health teachers in private school had significantly higher teaching self-efficacy than ones in public school. Conclusion: Given the fact that health teachers in elementary and private school had higher teachers' self-efficacy, an intervention to strengthen teachers' self-efficacy of health teachers in middle and high schools as well as ones in public school is required to help children and adolescents learn good health behaviors.

Purpose: The study aimed to investigate the factors associated with long hours of smartphone usage and to identify the characteristics of the high-risk group among female middle school students in South Korea. Methods: The study analyzed the data of 13,648 female middle school students using their own smartphone extracted from the 13th Youth Health Behavior Online Survey (2017). The factors related to using smartphones for a long time was analyzed by binomial logistic regression. The characteristics of the high-risk group was defined by a decision tree analysis. Results: The average hours spent on smartphone usage was 269.54 minutes per day. The significant factors associated with the long hours of smartphone usage were grade, living with parents, perceived household economic status, perceived academic achievement, stress, sadness and hopelessness, the main purpose of smartphone usage, drinking, body mass index, breakfast, and satisfaction with sleep quality. The subjects showing low academic performance and having breakfast four times a week or less were more likely to use their smartphone for a long time. Conclusion: Based on the results of the research, we need to establish intervention strategies focusing on the factors influencing long-time usage of smartphone. Particularly, the subjects who show poor academic performance and skip breakfast frequently should be considered as the high-risk group for spending long hours on smartphone usage.
