This study examined the moderating role of self-control and emotion regulation in the relationship between academic stress and mental health among Korean adolescents. The Korean Youth Panel Study (KYPS) was used as sample data with a total of 3121 $11^{th}$ grade students involved in this study. Hierarchical multiple regression was applied to test the moderation model following Baron & Kenny's (1986) model. Results revealed that self-control (for male adolescents) and emotion regulation (for female adolescents) played the role of moderators in the relationship between academic stress and mental health problems. Academic stress proved to have a negative effect on mental health of adolescents.

This paper develops a statistical mode which estimates mental and physical loads of light work from sinus arrhythmia (SA) scores. During experiments, various levels of mental and physical loads (respectively scored by information processing and finger tapping rates) were imposed on subjects and SA scores were measured from the subjects. Two methods were used in developing workload estimation model. One is an algebraic inverse function of a multivariate regression equation, where mental and physical loads are independent variables and SA scores are dependent variables. The other is a statistical multivariate inverse regression. Of the two methods, inverse function resulted in larger mean squqre error in predicting mental and physical loads. Hence, inverse regression model is recommended for precise workload estimation.

Various web browsers offer mouse gesture functions because they are convenient input methods. Mouse gestures enable users to move to the previous page or tab without clicking its relevant icon or menu of the web browser. To maximize the efficiency of mouse gestures, they should be designed to match users' mental models. Mental models of human beings are used to make accurate predictions and reactions when certain information has been recognized by humans. This means providing users with appropriate information about mental models will lead to fast understanding and response. A cognitive response test was performed in order to evaluate whether the mouse gestures easily associate with their respective functional meanings or not. After extracting mouse gestures which needed improvement, those were redesigned to reduce cognitive load via sketch maps. The methods presented in this study will be of help for evaluating and designing mouse gestures.

Purpose: The purpose of this study was to investigate the associations of mental health recovery to internalized stigma and meaning in life of community-dwelling people with mental disorder. Methods: Participants were 150 people with mental disorder who were enrolled at one of the community mental health institutions in D, S, and U cities, South Korea. Data analyses included a descriptive analysis, t-tests, ANOVA, Pearson's correlation coefficients, and stepwise multiple regression using SPSS 25.0 software. Results: There were significant mean differences in mental health recovery according to education, religion, residential status, diagnosis, and day program use status of people with mental disorder living in the community. The significant predictors of mental health recovery included presence of meaning, stigma resistance, diagnosis (Major depressive disorder), and search for meaning. The regression model explained 58.7% of mental health recovery. Conclusion: Improving meaning in life and stigma resistance will increase the chances of mental health recovery among community- dwelling people with mental disorder.

Purpose: This study was a part of preliminary survey for establishing Korean HPS(Health Promoting School) model which was originally suggested by WHO. Methods: Three elementary and middle schools were sampled in urban and rural area across three level of social-economic status, and survey was conducted on one class in each grade by random selection. To measure mental health and social and familial factors, self-esteem scale, self-efficacy scale, depression scale, family cohesion scale, parent-child communication scale, adolescent's mental health and problem behavior questionnaire(AMPQ), and other question items about family status and economic level were conducted. Students' mental health level was compared by region, sex, grade, and other familial and economic factors. Results: Familial and social factors such as economical and educational level of parents, number of family members were different between rural and urban area. Also, students of rural area got lower scores at self-esteem, self-efficacy, but higher scores at extroverted problem behavior than their urban counterparts. In pre-school students, high grade students' self-esteem, and family cohesion scores were lower than low grade students. And sexual differences were found across problem behavior domain and region in middle school students. Especially, the students of single-parent family and lower economic family got insistently low scores at various mental health related scales. Conclusion: These results should be considered, when the HPS model is designed and applied in Korea.

The study investigates mental models of scientifically gifted, middle school students when it comes to tides. This was done by analyzing facet of conceptual types for two contexts. We carried out two performance tasks of tide with different context. A large number of students showed different conceptual types by context. As a result of analyzing facet of conceptual types by context, there was a slight difference in content-specific facet, but a remarkable one in strategic facet. We classified four mental models about tide by configuring facets of conceptual types: (1) Tide model (2) Force model (3) Phase model (4) Hybrid model. The Tide model is scientifically accepted model, but Force model and Phase model are incorrect models, and Hybrid model is mixed model. In cases of Force model and Phase model, conceptual types concur with each other, but these types of students comprehend tides as a result of joined forces of Moon & Sun and phase change of Moon, respectively. Arranging low mental models in proportional order, Tide model (45.0%), Hybrid model (30.0%), Force model (12.5%), and Phase model (7.5%).

The purpose of this research was to investigate the mediation effect of bullying on the associations between children's overweight and obesity problem and mental health problems. Data from a subsample of 2,306 adolescents, who participated in the "child-youth synthesize survey" was utilized. The measurement and structural models were estimated using structural equation modeling. Partial and full mediation models were compared, and X2 difference test was conducted between the two models. The study results show that children's overweight and obesity problem have a direct effect on mental health problems. In addition, bullying was found to mediate the association between children's overweight and obesity problem and mental health problems. The analytic results confirmed that the model fit for the full mediation model was better than the partial mediation model when examining the mediating effect of bullying on the relations between children's overweight and obesity problem and mental health problems. Efforts to prevent mental health problems may require interventions for children's with overweight and obesity problems as well as inventions for reducing bullying in general.

Background: While attention has been paid to physical risks in the work environment and the promotion of individual employee health, mental health protection and promotion have received much less focus. Psychosocial risk management has not yet been fully incorporated in such efforts. This paper presents good practices in promoting mental health in the workplace in line with World Health Organization (WHO) guidance by identifying barriers, opportunities, and the way forward in this area. Methods: Semistructured interviews were conducted with 17 experts who were selected on the basis of their knowledge and expertise in relation to good practice identified tools. Interviewees were asked to evaluate the approaches on the basis of the WHO model for healthy workplaces. Results: The examples of good practice for Workplace Mental Health Promotion (WMHP) are in line with the principles and the five keys of the WHO model. They support the third objective of the WHO comprehensive mental health action plan 2013-2020 for multisectoral implementation of WMHP strategies. Examples of good practice include the engagement of all stakeholders and representatives, science-driven practice, dissemination of good practice, continual improvement, and evaluation. Actions to inform policies/legislation, promote education on psychosocial risks, and provide better evidence were suggested for higher WMHP success. Conclusion: The study identified commonalities in good practice approaches in different countries and stressed the importance of a strong policy and enforcement framework as well as organizational responsibility for WMHP. For progress to be achieved in this area, a holistic and multidisciplinary approach was unanimously suggested as a way to successful implementation.
