Objectives : The objective of this study was to identify the risky behavior subtypes in adolescents with depression, and the relationship between those subtypes and suicide attempt. Methods : Ninety adolescents who met the Diagnostic and Statistical Manual of Mental Disorders-4th edition criteria for major depressive disorder, dysthymia, or depressive disorder not otherwise specified participated in the study. Participants were interviewed about suicidal attempts, non-suicidal self-injuries. Smoking, drinking behaviors, and searching for the word "suicide" on the internet, negative life events including bulling-bullied experiences, and history of abuse were also included with questionnaires. Results : The results of cluster analysis showed that four risky behaviors were divided into three clusters : non-risky type, characterized by few risky behaviors ; delinquency type, which was characterized by smoking and drinking ; non-suicidal self-injury type. In non-suicidal self-injury type, percentage of girls was higher and clinical symptoms were more severe than delinquency type. In addition, delinquency type members could be a bully, while non-suicidal self-injury type members could be abused by a family member. Logistic regression analysis showed that both risky behavior subtypes were significant predictors of suicide attempt. Conclusion : These results suggest that two types of risky behaviors of depressed adolescents have an effect on the suicide attempts independently. Then, the implications and limitations of the study were discussed and directions for future studies were suggested.

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.

This study analyzed how mental health affects stress in adolescents. The subjects of the study were data of about 60,000 middle and high school students living in the country, using cross-tabulation data and chi - square test to analyze the relationship between stress and mental health of adolescents. As a result of the research, it was found that the adolescents exposed to the excessive stress showed a poor correlation with the recovery of the fatigue, while the adolescents with relatively low stress showed the good recovery of fatigue. In the case of mental illness, depression or despair, the students who answered that they were stressed showed a lot of experience. In the case of suicide ideation, suicide attempt, and suicide attempt, the number of attempts to commit suicide was high when the level of perceived stress was high similar to the result of previous analysis. This finding confirms that stress is an important factor in the quality of life in adolescent mental health. It can be used as a strategy and business to prevent the problem of youth suicide in modern society in advance by stress management.

Gene-environment interactions are important in pathogenesis of suicide or suicidal behavior. Twin and adoption studies and family studies show that genetic factors play a critical role in suicide or suicidal behavior. Given the strong association between serotonergic neurotransmission and suicide, recent molecular genetic studies have focused on polymorphisms of serotonin genes, especially on serotonin transporter and tryptophan hydroxylase genes. Some studies have revealed a significant interaction between s allele of the serotonin transporter gene and the risk of suicide attempt associated with childhood trauma. In addition, the polymorphism of brain-derived neurotrophic factor gene also may influence the effect of childhood trauma in relation to the risk of attempting suicide. Future studies should explore genetic and environmental factors in suicide or suicidal behavior and examine for gene and environment interaction.

Purpose: The purpose of this study was to develop and compare the prediction model for suicide attempts by Korean adolescents using logistic regression and decision tree analysis. Methods: This study utilized secondary data drawn from the 2019 Youth Health Risk Behavior web-based survey. A total of 20 items were selected as the explanatory variables (5 of sociodemographic characteristics, 10 of health-related behaviors, and 5 of psychosocial characteristics). For data analysis, descriptive statistics and logistic regression with complex samples and decision tree analysis were performed using IBM SPSS ver. 25.0 and Stata ver. 16.0. Results: A total of 1,731 participants (3.0%) out of 57,303 responded that they had attempted suicide. The most significant predictors of suicide attempts as determined using the logistic regression model were experience of sadness and hopelessness, substance abuse, and violent victimization. Girls who have experience of sadness and hopelessness, and experience of substance abuse have been identified as the most vulnerable group in suicide attempts in the decision tree model. Conclusion: Experiences of sadness and hopelessness, experiences of substance abuse, and experiences of violent victimization are the common major predictors of suicide attempts in both logistic regression and decision tree models, and the predict rates of both models were similar. We suggest to provide programs considering combination of high-risk predictors for adolescents to prevent suicide attempt.

Purpose: The study explored the influence of the suicide of two famous entertainers on the suicide attempts of the public. Method: The subjects of the descriptive study were 888 suicide attempt patients recruited from October 2007 to September 2009 in an emergency centre located in S-city. The research tools were developed at the Centre for Disease Control. Results: The frequency of suicide attempts during the 6 months and 12 months preceding and following the gas-related suicide of celebrity A were ${\chi}^2$=18.14 and ${\chi}^2$=25.97, respectively, and both were significant(both p<.001). The frequency of suicide attempts of the 6 and 12months before and after the release of report of celebrity B's hanging suicide were ${\chi}^2$=3.85 and ${\chi}^2$=3.47, respectively, and both were significant (both p<.05). Conclusion: These results showed that reports of suicide of celebrities influences suicide attempts of the public. Multiple factors that can influence suicide attempts should be further identified and researched.

The purpose of this study is to conduct an in-depth interview on 5 middle aged women who have attempted suicide in the past and to explore their suicide attempts and the vivid empirical value of life after the attempt. The collected data were analyzed using Giorgi's phenomenological approach. The data analysis resulted in 21 sub categories and 7 essential categories. Study participants experienced an-'selected death at the end of a cliff', 'standing on the border of life and death', 'life became clear after escaping delusion', 'working toward life once again', 're-evaluating their past life and discovering new possibilities', 'experiencing the vividness of life here', 'spiritual growth and deeper insight'. Such results offer a discussion on existence toward self-completion, and hold significance in that it increased our in depth understanding and recognition beyond the narrow perceptions of individuals who attempt suicide.

Objectives : The aim of this study was to investigate the factors including possibility of bipolar disorder that are related to intensity of suicidal idea. Methods : The study subjects consisted of 50 patients who did suicidal attempt and treated at the Inje University Haeundae Paik Hospital Emergency Room. All participants underwent psychiatric interview and underwent Columbia Suicide Severity Rating Scale(C-SSRS), Beck Depression Inventory(BDI), Korean Version of Mood Disorder Questionnaire(MDQ) and Bipolar Spectrum Diagnostic Scale(BSDS) to evaluate patient's suicide attempt, severity of depression and possibility of bipolar disorder. Results : Compared to non-high risk group, suicide high risk group showed significantly higher BDI(p<0.001) and intensity of ideation(IOI) in C-SSRS(p<0.001). Also intensity of ideation(IOI) was correlated with Mood Disorder Questionnaire(MDQ) bipolarity positive(p=0.033). Conclusions : The present study indicated that possibility of bipolar disorder plays a significant role in suicide attempters. Assessment of suicide ideation severity and possibility of bipolar disorder should be considered when suicide attempters come to emergency room.

Introduction : Suicide in Korea has increased to 31.2 persons per 100,000 population, the world's highest level. Suicide is the 10th leading cause of death in the world, but in Korea, it is 4th leading cause of death. Therefore suicide is a serious problem in Korea. Many suicide prevention strategies have been proposed. Despite efforts to prevent suicides in Korea, a steady increases in the number of suicides has been brought into question the effectiveness of suicide prevention activities in Korea. Methods : Strategy of restricting suicide methods in many countries was reviewed. Systematic approach to restrict suicidal methods in Korea is proposed. Results : Restricting suicide methods is one of the effective suicide prevention strategies employed in the UK and other countries. Since many suicides occur impulsively, suicide attempt lethality is an important factor in determining the rate of deaths in suicidal attempts. Physical restriction of suicide methods is important in preventing suicide, but restriction of cognitive access to information about suicide and suicide method is more important in preventing suicide. In particular hanging is one of the most common methods of suicides in Korea, it is crucial to develop strategies to prevent suicide by hanging cognitively. Also information about suicide should be properly controlled. To do this, suicide news reporting guidelines should be observed, and website makers whose websites provoke thoughts about suicide should be more strictly sanctioned. Conclusion : Restricting suicide methods along with other suicide prevention plans may be the most effective way to prevent suicide in Korea.

Purposes: The purposes of this study were ① to identify the rate of suicide attempts, and ② to investigate relevant variables(family dynamic environment, personality factors) and risk factors for attempting suicide among Korean adolescents. Method: Data were collected through a questionnaire survey. Internal consistencies for this questionnaire ranged from 0.63 to 0.88. Nine hundred and twenty two adolescents were surveyed (delinquent : 367, student : 555), using a proportional stratified random sampling method. Statistical methods employed were chi-square, t-test, and logistic regression analysis. Results: ① The rate of suicide attempts was 10.8％ for the total sample, and the delinquents(19.6％) had a higher rate of suicide attempts than the students(5.1％). ② Adolescents attempting suicide had a greater dysfunctional family dynamic environment and more maladaptive personality than those who did not attempt suicide. ③ Risk factors for suicide attempts among Korean adolescents were way of coping, psychosomatic symptoms, and parental child-rearing attitudes, in that order. Conclusions: Suicide and suicidal behaviors are multifaceted events. For suicide prevention, there is a need to make an independent assessment of the variables such as familial problems, personality and dynamic environment of the families of the adolescents.
