South Korea has the highest reported suicide rate among all countries belonging to the Organization for Economic Cooperation and Development. Nitrogen is a colorless, odorless and nontoxic gas. Nitrogen gas has, however, been recently used as a method of attempted suicide, its nontoxity notwithstanding. We herein report on an unusual case involving a 30-year-old male who presented with symptoms after a suicide attempt by nitrogen inhalation. Diffusion-weighted imaging of his brain was showed curvilinear high signal intensity in the bilateral frontal and right occipital cortices, with subtle low apparent diffusion coefficient value. In addition, T2-weighted images and fluid attenuated inversion recovery images revealed subtle high signal intensity in the bilateral frontal cortices, basal ganglia and occipital cortices with contrast enhancement.

Purpose: To identify the types and characteristics of subjective structures among nursing students toward individuals who attempt suicide. Methods: A group of 32 third- and fourth-year nursing students with experience in clinical practice rated 35 Q-statements on a nine-point scale according to their opinion. Data analysis was conducted using the PC-Quanl program. Results: Subjectivity among nursing students toward individuals who attempt suicide was analyzed for three types. Type 1 (social responsibility emphasis) subjectivity recognizes the social responsibility for suicide attempts and emphasizes the importance of social support systems as a preventive effort. Type 2 (rational reprimand) subjectivity emphasizes the willpower and effort to overcome challenges in life, because happiness and unhappiness are dependent on one's thoughts and will. Type 3 (situation acceptance) subjectivity regards the suicide attempt as an optional means to avoid a deeply strenuous, painful, and difficult situation. Conclusion: This study investigated the subjectivity of nursing students toward individuals who attempt suicide and to provide a better understanding of them. In addition, the development of training programs that take advantage of the subjective characteristics of individuals based on subjectivity types demonstrated in this study is expected to provide nursing students with useful educational materials for their future careers as nurses.

The Korea Convergence Society. The purpose of this study was to examine the effect of suicidal attitude, perception of life, and depression on adolescents' suicide(ideation, plans, attempts). Data on general characteristics, the Attitude Toward Suicide, the Perception about Life, and the Korean version of Center for Epidemiologic Studies Depression Scale-Revised were collected in 889 second-year middle school students in the I area. Two hundreds forty six students (27.67%) indicated they had suicide ideation, 85 had suicide plans (9.56%), and 46 had suicide attempts (5.17%). The proportion of female students was significantly higher than that of male students. The suicide indices (ideation, plans, attempts) increased as one shows lower body image satisfaction, higher depression, lower subjective mental and physical health, and lower leisure satisfaction. Predictors of suicide ideation included suicidal attitude (solution and permissiveness), depression, subjective mental health, and body image satisfaction. Predictors of the suicide plan were permissiveness and solution among suicidal attitude, and depression, subjective mental health, and those of suicide attempts were permissiveness and depression. Conclusion: This study suggests that much effort is required to decrease depression and improve perception of life and suicidal attitude in the suicide prevention education for adolescents.

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.

Background: Although Korea ranks first in the suicide rate of elderly individuals, there is limited research on those who attempt suicide, with preventive measures largely based on population-based studies. We compared the demographic and clinical characteristics of elderly individuals who attempted suicide with those of younger adults who visited the emergency department after suicide attempts and identified the factors associated with lethality in the former group. Methods: Individuals who visited the emergency department after a suicide attempt from April 1, 2017, to January 31, 2020, were included. Participants were classified into two groups according to age (elderly, ≥65 years; adult, 18-64 years). Among the 779 adult patients, 123 were elderly. We conducted a chi-square test to compare the demographic and clinical features between these groups and a logistic regression analysis to identify the risk factors for lethality in the elderly group. Results: Most elderly participants were men, with no prior psychiatric history or suicide attempts, and had a higher prevalence of underlying medical conditions and attributed their attempts to physical illnesses. Being sober and planning suicide occurred more frequently in this group. In the elderly group, factors that increased the mortality rate were biological male sex (p<0.05), being accompanied by family members (p<0.05), and poisoning as a suicide method (p<0.01). Conclusion: Suicide attempts in elderly individuals have different characteristics from those in younger adults and are associated with physical illness. Suicides in the former group are unpredictable, deliberate, and fatal. Therefore, tailored prevention and intervention strategies addressing the characteristics of those who are elderly and attempt suicide are required.

Purpose: This study was designed to analyze recent trends in adolescent suicide intervention research in Korea and to suggest future research directions in this area. Methods: Studies Thirty-four studies selected from http://www.riss4u.net over the for last 20 years were analyzed by field and design of the study, study participants, and the outcome variables used in intervention studies. Results: Nineteen (55.9%) of the 34 studies were conducted in the fields of welfare (9), psychology (5) and nursing science (5). Ordinary adolescents were the most frequently studied participants. A nonequivalent control group pretest-posttest design was used in twenty one (61.7%) of the 34 studies. The most frequently measured outcome variables were depression, suicidal ideation and self-esteem. Conclusion: These results suggest that research on adolescent suicide intervention programs is expanding with a focus on ordinary adolescents as and subjects. In order to prevent suicide, research on family, teachers, and friends, who all are important parts of a teenager's support system, is needed. It is also necessary to develop a post-management intervention program to prevent recurrence in high-risk teenagers who have attempted suicide.

Purpose: The suicide rate of adolescents in Korea is increasing annually. Therefore, this research was done to identify the suicide attempt rate of middle and high school students and to identify factors that influence suicidal attempts. Methods: The Korea Youth Health Risk Behavior Web-based Survey (2007) was used as data. Discriminant analysis and logistic regression were performed to analyze the data depending on gender to consider the gender difference in assessing the influence of each independent variable on suicidal attempts. Results: Discriminant analysis according on gender showed that 13 factors correlated with suicidal attempts for boys, and 20 factors for girls. The most highly correlated factors were smoking, depression and inhalation experience. For inhalation experience, boys had 2.7 times higher possibility of suicide attempts (95% CI 1.8-3.0) and girls, a 2.4 times higher possibility (95% CI 1.7-3.5). Conclusion: The results of the study indicate a need to classify adolescents for expectation of suicide risk and high danger for suicidal attempts through, and introduce suicide prevention programs for these adolescents. In particular, it is necessary to start intervention with students who smoke, have sexual and inhalation experiences and high levels of depression.

This study is a secondary data analysis study using the 1^st Panel Survey of School Dropouts in Korea for investigating predictors of suicide attempts in out-of-school youths (OSYs). Data analysis were performed using the SPSS 26.0 statistical program. Suicide attempts were reported in 62 (8%) of the 776 participants included in the study. Logistic regression analysis revealed that suicide attempts before school dropout (OR=10.66), experience of violence victimization (OR=6.97), alcohol consumption (OR=3.73), depression (OR=2.62), parental attachment (OR=0.47), peer relationships (OR=0.63) before school dropout were significant predictors of suicide attempts. Prevention of suicide attempts by OSYs should be preceded by confirmation of their experience in suicide attempts before school dropout. In addition, it is required to establish a suicide prevention program considering psychological situations, interpersonal relationships, and violence experiences.

Suicide has been a long-standing problem for global public health, along with almost 800,000 deaths from suicide worldwide in 2016, accounting for 1.4% of all deaths. South Korea was ranked first in suicide mortality in 2018 among countries in the Organization for Economic Cooperation and Development. This study aimed to suggest up-to-date information about suicide-related indicators such as the rate of suicidal ideation, suicide attempt, and suicide death, and its trends by applying sampling weight to make it nationally representative. In this study, we used the data sources: Korea National Health and Nutrition Examination (KNHANES, '07-13, '15-18), Korean Community Health Survey (KCHS, '08-09, '13, '17), Korean Wealth Panel Study (KOWEPS, '12-18), Korea Health Panel Survey (KHP, '10-13), and Statistics Korea (1983-2017). The rate of suicidal ideation as recent year was 4.73% (KNHANES, '17), 6.96% (KCHS, '17), 2.29% (KOWEPS, '18), and 5.39% (KHP, '13). That of suicide attempt as recent year was 0.51% (KNHANES, '18), 0.32% (KCHS, '17), and 0.15% (KOWEPS, '18). Annual percentage change (APC) of suicidal ideation was -15.4% (KNHANES, '07-13, '15, '17), -2.5% (KCHS, '08-09, '13, '17), -10.8% (KOWEPS, '12-18), and -10.9% (KHP, '10-13). APC of suicide attempt was -4.4% (KNHANES, '07-13, '15-18), -4.4% (KCHS, '08-09, '13, '17), and -13.6% (KOWEPS, '12-18). APC of death by intentional self-harm was -1.25% (Statistics Korea, '07-18). All suicide-related indicators were found to be decreasing in the overall from 2009. Individuals with lower income level were more likely to experience suicidal ideation and suicide attempts. Even though suicide rate had been continuously decreasing from its highest point in 2011 (suicide rate: 31.7 per 100,000 population) to 2017 (suicide rate: 24.3 per 100,000 population), it increased again in 2018 (suicide rate: 26.6 per 100,000 population). This information would be grounded on policy implementation for suicide prevention, thus continuous data observation is necessary.
