The rate of suicide is the 5th leading cause of death in Korea. Moreover, suicide is the 1st cause of death in from 2nd to 4th decade. In order to treat suicide attempters who have visited the emergency room and to prevent retries, it is necessary to understand the nature of the suicide and to take the right approach. Suicide is more than doubled in women, and retry rates are high among patients with a history of suicide. Suicidal means are throat, fall, gas poisoning, poisoning and drowning. All suicide attempters should suspect and treat cervical spine injury and airway management, and rapid hyperbaric oxygen therapy is recommended for carbon monoxide addicts. Interviewing a suicide attempter requires a sympathetic attitude and examines the underlying depression or adaptation disorders. Interdisciplinary care with mental health departments is necessary, and interventions in emergency roombased suicide attempt management work can be helpful to connect with the community.

The purpose of this study is to identify and analyze suicide factors of adolescents using the Random Forest algorithm. According to statistics on the cause of death by the National Statistical Office in 2019, suicide was the highest cause of death in the 10-19 age group, which is a major social problem. Using machine learning algorithms, research can predict whether individual adolescents think of suicide without investigating suicidal ideation and can contribute to protecting adolescents and analyzing factors that affect suicide, establishing effective intervention measures. As a result of predicting with the random forest algorithm, it can be said that the possibility of identifying and predicting suicide factors of adolescents was confirmed. To increase the accuracy of the results, continuous research on the factors that induce youth suicide is necessary.

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.

Background: External-cause mortality is an important public health issue worldwide. Considering its significance to workers' health and inequalities across industries, we aimed to describe the state of external-cause mortality and investigate its difference by industry in Republic of Korea based on data for 2018. Methods: Data obtained from the Statistics Korea and Korean Employment Information System were used. External causes of death were divided into three categories (suicide, transport accident, and others), and death occurred during employment period or within 90 days after unemployment was regarded as workers' death. We calculated age- and sex-standardized mortalities per 100,000, standardized mortality ratios (SMRs) compared to the general population and total workers, and mortality rate ratios (RRs) across industries using information and communication as a reference. Correlation analyses between income, education, and mortality were conducted. Results: Age- and sex-standardized external-cause mortality per 100,000 in all workers was 29.4 (suicide: 16.2, transport accident: 6.6, others: 6.6). Compared to the general population, all external-cause and suicide SMRs were significantly lower; however, there was no significant difference in transport accidents. When compared to total workers, wholesale, transportation, and business facilities management showed higher SMR for suicide, and agriculture, forestry, and fishing, mining and quarrying, construction, transportation and storage, and public administration and defense showed higher SMR for transport accidents. A moderate to strong negative correlation was observed between education level and mortality (both age- and sex-standardized mortality rates and SMR compared to the general population). Conclusion: Inequalities in external-cause mortalities from suicide, transport accidents, and other causes were found. For reducing the differences, improved policies are needed for industries with higher mortalities.

Objectives: This study is to gain an understanding of the characteristics of suicides committed by university students in Korea by assessing news reports. Methods: A total of 97 news reports on university student suicides on daily newspapers and TV newscasts from 2000 to 2011 are included in this study. Analyses were performed on sociodemographic characteristics of suicided university students and temporal and other characteristics of the suicides. Results: Suicide rate was higher among males than females. The most frequently used method of suicide was jumping off while the most common place was the students’ residence. Issues related to academic and financial problems topped as the reasons for suicide. There were no differences in the reasons for committing suicide by school year and enrollment, but the location and season of committing suicide differed by reasons for suicide. Conclusions: Implication of this study, discussion on the results and suggestions for suicide prevention are discussed.

Purpose: This study aims to analyze the number of suicide deaths in women, trends in suicide mortality, characteristics of suicide by age, and outcomes of suicide means over the past decade (2011-2021) in South Korea. Methods: Using cause of death data from Statistics Korea, an in-depth analysis of Korean women's suicide trends was conducted for the period of 2011-2021. Results: In 2021, women's suicide death in Korea was 4,159, a rate of 16.2 per 100,000 population. The rate increased by 1.4% from the previous year. Since 2011, women's suicide rate has been on a steady downward trend, but since 2018, it has been on the rise again. Suicide rates among women in their 20s and 30s have increased, especially since the coronavirus disease 2019 pandemic, and suicide rates among women over 70 years remain high. As compared to 2011, pesticide poisoning and hanging among the means of suicide have decreased significantly, while drug and carbon monoxide continue to increase. Conclusion: Suicide rates for Korean women in their 20s and 30s have increased significantly in recent years, and those for women over 70 years remain high. Therefore, it is necessary to investigate the causes and establish national policies for targeted management of these age groups, which contributes significantly to the rising suicide rate among Korean women.

Purpose: The purpose of this study is to identify the effects of suicide reports by mass media and social support on suicide ideation for college students. Methods: Participants are 350 undergraduate students in one university. This study uses three questionnaires: Perception and Attitude toward Suicide Reports, Social Support, and Suicidal Ideation. The SPSS/WIN 12.0 program is used to analyze the data. In particular, the participants' biographical data are analyzed into frequency and percentage. The degrees of suicide reports, social support, and suicide ideation are calculated into Mean and SD. Moreover, the suicide ideation by suicide report and social support are analyzed by the two-way analysis of variance (ANOVA). Results: This study reveals that college students have an average of 30 minutes to one hour news time a day (38.9%) and have at least one suicide report in a month (30.3%). 79.7% participants believe that the suicide report of mass media results in the cause of the copycat suicide. In terms of suicide report and suicide ideation, the types of mass media (F (4,340)=2.41, p<.05) and suicidal urge (F (1,340)=31.23, p<.01), respectively, have significant influences on suicide ideation. On the other hand, the social support and suicide ideation, whether college students have their mentors (F (1,328)=13.26, p<.001) and/or careres (F (1,328)=26.84, p<.001) have significant influences on suicide ideation. Conclusion: College students have higher suicide ideation at news by internet site rather than by radio, TV, and so on. Moreover, college students who have a suicide feeling in the last one year, have more suicide ideation than who have not. On the other hand, college students who have a mentor and carer tend to have less suicide ideation.

Objectives: Adolescent suicide, a major cause of adolescent death, is affected by various factors, including attitudes toward suicide. This study investigated the association between parenting style and adolescents' attitudes toward suicide and the mediating role of attitude toward suicide between parenting style and suicidal ideation. Methods: We surveyed 1,071 adolescents from eight middle schools in Incheon, Korea. The survey included sociodemographic information, attitudes toward suicide, perception of parenting style, depression severity, and suicidality. Results: Students in the authoritarian parenting group had a more permissive attitude toward suicide compared with the democratic and permissive parenting groups. These students considered that suicide is justified in certain situations and that choosing suicide is an individual's right. They also had a negative attitude toward talking about suicide or intervening in others' suicide. This association remained statistically significant after adjusting for the impact of confounding factors that could affect attitudes toward suicide, except for suicidal processes and preparedness to prevent suicide. In the mediation analysis, we observed that some factors of the attitudes toward suicide mediated between authoritarian parenting attitudes and suicidal ideation, namely, suicide as a right, preventability, suicide as normal/common, preparedness to prevent suicide, and resignation. Conclusion: This study revealed the significant impact of parenting style on children's attitudes toward suicide. Educating parents about the appropriate parenting attitudes-sympathetic and rational-can help prevent youth suicide.

The increasing suicide rate is a serious problem in Korea. Because of increased awareness of suicidality as a problem and because completed suicide is the fourth leading cause of death, it is very important to assess the risk of suicide. The purpose of this review is to provide a systematic examination of predictive validity of measures of suicidal ideation and behavior. A number of instruments are described as useful for identifying individuals "at high risk" for suicidal behavior. However, the predictive validity for most suicide measures has not been established. The present review only includes suicide assessment instruments with published predictive validity. In addition to evaluating the suicide assessment with respect to predictive validity, the present review describes and summarizes the psychometric properties of each measure. In conclusion, because of the complexity of studying the risk of suicide and the paucity of well-designed studies, it is extremely difficult to compare and generalize these findings. In addition, only a few instruments, such as the Scale for Suicide Ideation, Suicide Intent Scale and the Beck Hopelessness Scale, have been found to be significant risk factors for completed suicide. Another problem in the field involves that there have been few suicide measures designed for elderly populations. Clearly, future research is needed to investigate the predictive validity of standardized measures for completed suicide, especially targeting elderly populations.

2011. 3. 자살예방 및 생명존중문화 조성을 위한 법률(이하 '자살예방법'이라 한다)이 제정되었다. 자살예방법의 제정의미는 사람의 삶의 일부인 질병을 넘어서 죽음을 막기 위한 국가적 개입의 시작을 의미하는 것이기도 하다. 그러나 국가는 이러한 법을 만들기 이전부터 자신의 본연의 임무로서 국민의 삶을 건강하게 보존시켜야 할 의무가 있어 왔다. 역사적으로 자살이 금지된 이유는 노예는 주인에게, 군인은 왕에게, 교인은 신에게 복속된 생명체여서 죽음을 자신의 뜻대로 할 수 없다는 의미를 가지고 있다. 역사에 나타났던 주인 왕 신의 역할을 현대 사회에서는 국가가 대신한다. 국가는 과거 주인이나, 왕, 신이 맡았던 역할을 대신하면서 국민의 자살행위들에 개입하기 시작한다. 자살자는 죽었기 때문에 처벌할 수는 없지만, 그에 개입하는 자살관여자(형법상 자살교사자, 자살방조자 등)를 처벌하고, 자살시도행위에 대해서는 건강보험급여를 제한하며(국민건강보험법 제53조에 의한 고의행위에 대한 급여제한), 군인의 근무기피 목적의 자상(自傷, 군형법 제41조)을 처벌한다. 사람의 의식적이고, 의도적인 자기생명의 절단은 주로 사회적 법적 보호들로부터 배제되어 있을 때 발생한다. 정신질환자 빈곤자 노령자 등의 자살이 높은 이유는 그들이 일정한 사회적 법적 보호들로부터 떨어져 나왔기 때문이다. 사회적 법적으로 보호받는 존재였다가 그러한 보호들로부터 배제되거나 탈락하는 것(이혼이나 해고) 또한 마찬가지이다. 정신질환 또한 사회적 배제의 장치가 작동되어 그를 법적 보호의 바깥에 두면서 그는 불안한 생명이 된다. 이러한 사회적 법적 배제의 시스템을 완화하고, 그러한 배제의 공간에 있는 사람들을 사회적으로 결속시키는 것이 자살예방의 근본적 해결책이 될 수 있다. 사회적 배제(social exclusion)의 시스템은 정신질환자뿐만 아니라 보통의 사람들에게도 삶의 두려움을 강화시켜 원하지 않는 자살을 부추긴다. 사회적 법적 배제의 완화를 위한 노력이 자살예방의 근본적 치유책이라 보고서 본 연구에서는 자살예방법을 사회적 법적 배제의 완화라는 관점에서 비판적으로 고찰해 본다.
