Purpose: In South Korea, suicide mortality has rapidly increased, so it has become a major public health concern. Multicultural adolescents are regarded as a high-risk group due to their situation. In this study, we compared the prevalence and risk factors of suicide ideation between Korean and multicultural adolescents. Methods: Data from the eleventh Korean Youth Risk Behavior Web-based Survey (2015), collected by the Korean Centers for Disease Control and Prevention, were statistically analyzed using the descriptive statistics and multivariate logistic regression. The total participants were 63,376 in numbers. They were composed of 62,649 (98.9%) Korean and 727 (1.1%) multicultural adolescents. Results: I found that the prevalence of suicide ideation was significantly higher among the multicultural adolescents (15.8%) compared with those of Korean (11.3%). The risk factors of suicide ideation in the Korean group were co-residence without family, poor perceived health status, depressive mood, high stress level, poor perceived happiness level, and experience of violence. Conversely, the risk factors of the multicultural group were smoking, depressive mood, and experience of violence. Conclusion: These findings suggest that appropriate and practical prevention strategies should focus on psychological and environmental factors in order to prevent suicide ideation and reduce suicide behavior in Korean and multicultural adolescents.

An exhibitional suicide is a case of death that the purpose is to demonstrate one's own real intention for others. This exhibitional suicide has a few characteristics that are different from a suicide: seriousness of suicide intention, a method of suicide attempt, and the place of a suicide. In other words, an exhibitional suicide lacks suicide intention, uses a slower method of death, and attempts a suicide at the place which others can easily find. In this light, this paper ascertains that a fair number in poisoning deaths are an exhibitional suicide on the basis of the result of an autopsy by department of forensic medicine school of medicine, Kyungpook National University. The research also confirms that juveniles and women attempt a suicide as often as adults and men, and a great number of suicides are indeed an exhibitional suicide. In terms of a commercial law, many specialists see an exhibitional suicide as an accidental death. However, if we consider an exhibitional suicide as an accidental death, we cannot verify the authenticity of death in an accident. In addition, if we observe the purpose of insurance and suicide exemption period of insurance company, we rather get to know to distinguish an exhibitional suicide from an accident. According to the research, most of the exhibitional suicide results from little or no-relation with others. Therefore, a little interest from family, friend, and neighbor plays a pivotal role in preventing this suicide. Finally, an effort to build database concerning an exhibitional suicide by a psychological autopsy will help people access a plenty of statistical materials and facilitate further study about an exhibitional suicide.

Purpose: The purpose of this study is to examine the effects of clinical art therapy programs utilized at schools on adolescents' suicidal thoughts and stress relief and to validate their effectiveness as a type of adolescent suicide prevention program. Methods: 12 sessions of clinical art therapy for youth suicide prevention were provided, once a week for 90 minutes, for 20 students at five middle schools in Seoul who were at high risk of committing suicide. By using the paired sample t-test, the study presented qualitative data on the analysis of pre- and post- questionnaires and on the subjects' EEG test and saliva test. Results: First, through the clinical art therapy program, the subjects' happiness index improved significantly while their scores of depression and suicidal ideation (suicidal thoughts) decreased. Second, in the EEG and saliva test conducted after the art therapy sessions, emotional stability increased and stress was reduced significantly. Third, according to the results of pre- and post- K-HTP tests and individual activities, the subjects started to recognize the seriousness of suicide and show emotional stability and positive changes in overall attitudes, valuing the rights and life of their own 'precious selves' (self respect). Conclusion: The results of this study indicate that the clinical art therapy program is significantly effective at preventing suicidal ideation by reducing suicidal impulses and depression, by increasing the happiness index, which can serve as a protective factor against suicide, and by increasing emotional stability while reducing stress. Based on the results, there is a need to develop policy measures regarding art therapy programs which can be utilized at schools.
