Methods: Data were collected using a questionnaire to measure perceived smartphone addiction and physical and mental health of 314 female students attending a college located in D city from April 9 to May, 31, 2019. The collected data were analyzed using descriptive statistics, 𝑥² test, t-test and stepwise multiple regression with SPSS 18. Results: The respondents were classified into two groups, the perceived smartphone addiction group (29.3%) and the perceived smartphone non-addiction group (70.7%). Perceived smartphone addiction was significantly different according to daily smartphone usage time (p<.001), smartphone usage fee (p=.005), most satisfying thing about using smartphones (p=.006) and importance of smartphones in daily life (p<.001). The perceived smartphone addiction group had more physical health problems (p=.001) and more mental health problems (p<.001). The factors affecting physical health were perceived smartphone addiction and importance of smartphones in daily life, with 62% of explanatory power (F=10.15, p<.001). As for mental health, the affecting factors were also perceived smartphone addiction and importance of smartphones in daily life, with 87% of explanatory power (F=14.52, p<.001). Conclusion: It is important to raise awareness of smartphone addiction including its negative impact on physical and mental health, reduce smartphone usage time, and build offline social relationships.

Objectives Ketamine has been reported to have antidepressant effects or psychotomimetic effects. The aim of this study was to investigate the behavioral effects of ketamine treatment at various sub-anesthetic doses in adolescent and adult naïve mice. Methods In each experiment for adolescent and adult mice, a total of 60 male Institute of Cancer Research mice were randomly divided into 6 groups, which were intraperitoneally treated with physiological saline, 10, 20, 30, 40, and 50 mg/kg ketamine for consecutive 3 days. At 1 day after last injection, the locomotor and depressive-like behaviors were evaluated in mice, using open field test (OFT) and forced swim test (FST), respectively. Results In case of adolescent mice, ketamine dose was negatively correlated with total distance traveled in the OFT (Spearman's rho = -0.27, p = 0.039). In case of adult mice, we found significant positive correlation between ketamine dose and duration of immobility in the FST (Spearman's rho = 0.45, p < 0.001). Immobility time in the 50 mg/kg ketamine-treated mice was significantly higher compared to the saline-treated mice (Dunnett's post-hoc test, p = 0.012). Conclusions We found that the repeated treatment with ketamine could decrease the locomotor or prolong the duration of immobility in mice as the dose of ketamine increased. Our findings suggest that sub-anesthetic doses of ketamine might induce schizophrenia-like negative symptoms but not antidepressant effects in naïve laboratory animals.

Purpose: The purpose of this study was to investigate the effect of exercise on mental health in female elementary school teachers. Methods: The subjects were 1,861 female elementary school teachers in Seoul. Data were collected through an online survey from November 16 to December 7, 2008. Collected data were analyzed by descriptive statistics, ${\chi}^2$-test, t-test, one way ANOVA and Scheff$\acute{e}$ test, using IBM SPSS 20.0 program. Results: Not many female elementary school teachers were engaging in exercise. Even though their perception of stress and degree of depression were high, the rate of suicidal thoughts were low. The perception of stress was lower in the female teachers who engaged in walking or high-intensity workout than those who did not. The teachers who walked or stretched for exercise showed a lower rate of depression than those who did not and the teachers who walked for exercise displayed a lower rate of suicidal thoughts.

Purpose: This study was intended to integrate the evidence of intervention for child and adolescent perpetrators of school violence through an integrative literature review. Methods: Using combinations of the terms 'bullying', 'school violence', and 'intervention' as key words, the researchers searched eight electronic databases for relevant studies. Fifteen studies were selected through full-text screening of related research published in academic journals before June 2018. The framework was used to identify the selected studies' intervention patterns and classify the various intervention components. The extracted intervention components were grouped into potential themes to determine whether the researchers clearly showed the interventions in the studies. Results: The intervention components of 15 selected studies were categorized into five themes: 1) Utilizing intervention techniques for voluntary participation, 2) Enhancing self-awareness, 3) Strategies to improve emotional intelligence, 4) Promoting interpersonal skills, and 5) Emphasis on responsibility through future vision experience. Conclusion: As a result of analyzing interventions for children and adolescent perpetrators of school violence, five components were derived. It is suggested that these components should be considered in the field, and intervention programs development and research using them are needed.

Objective The aims of the present study were to explore the occurrence of childhood trauma and importantly to determine the impacts of childhood trauma on psychosocial features in a Chinese sample of young adults. Methods A survey was carried out in a group of 555 university students by using Childhood Trauma Questionnaire (CTQ), Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS), Dysfunctional Attitudes Questionnaire (DAS), Eysenck Personality Questionnaire (EPQ), and Social Support Rating Scale (SSRS). The moderate-severe cut-off scores for CTQ were used to calculate the prevalence of childhood trauma, and then psychosocial features were compared between individuals with and without childhood trauma. Results A proportion of 18.6% of university students had self-reported childhood trauma exposures. Subjects with childhood trauma reported higher scores of SDS, SAS, DAS, and psychoticism and neuroticism dimensions of EPQ (t=4.311-5.551, p<0.001); while lower scores of SSRS and extraversion dimension of EPQ (t=-4.061- -3.039, p<0.01). Regression analyses further revealed that scores of SAS and DAS were positively (Adjusted B=0.211-0.230, p<0.05), while scores of SSRS were negatively (Adjusted B=-0.273- -0.240, p<0.05) associated with specific CTQ scores. Conclusion Childhood trauma is still a common social and psychological problem. Individuals with childhood trauma show much more depression, anxiety, distorted cognition, personality deficits, and lower levels of social support, which may represent the social and psychological vulnerability for developing psychiatric disorders after childhood trauma experiences.

Objectives: This study was conducted to investigate the relationships among job stress, job satisfaction, and mental health in marine officers. Methods: The researchers gathered data on marine officers working at a harbor in Chungcheong Province, South Korea, using a self-reported questionnaire. Mental health was measured by the Symptom Checklist-90-Revision (SCL-90-R), and general characteristics including socioeconomic factors, job stress, and job satisfaction were measured by structured questionnaires. Multiple regression analysis was performed to investigate the relationships among job stress, job satisfaction, and mental health status according to the symptom dimensions of the SCL-90-R. Results: Among the marine officers, obsessive-compulsive behavior, depression, and somatization were the most problematic symptoms. Those who reported poor health, low job satisfaction, and high job stress had a higher prevalence of psychoticism, somatization, depression, anxiety, and phobic anxiety. Conclusions: An occupational health system should be introduced that would regularly check the mental health of marine officers in charge of ships and sailors, in order to help reduce their stress levels, enhance their job satisfaction, and thereby improve their mental health.

Objectives : The aim of this study was to examine attitudes of middle-school students toward happiness, suicide, and factors associated with suicide. Methods : A self-administered questionnaire was used in a cluster sample of 1,319 middle-school students (male 793, female 526). Data were obtained on a wide range of constructs regarding their attitude towards happiness, suicidal ideation and attempts, and factors associated with suicide. Results : Middle-school students choose 'love within family' as most important factor for their happiness. Subjective mental health status was mostly associated with happiness. Subjects in lower socioeconomic status tended to respond their mental health status was not good and have more suicidal idea. 48.7% of subjects had permissive attitudes toward suicide, especially, girls. However, 65.0% responded that suicide was preventable problem. Compared to older people, middle-school students perceived that environmental factors were more important than innate and personal factors for suicide. Conclusion : Results of the study indicate that middle-school students have permissive attitudes toward suicide, but positive attitudes for the prevention of suicide. This suggest that education in these age group could be effective for the prevention of suicide. Also, approaches to suicide prevention programs should be developed based on the family intervention. Especially, we should care about girls and adolescents in lower socioeconomic status.
