Purpose: The purpose of this study was to investigate suicidal ideation and its associated factors according to sex in the elderly, by focusing on socio-demographic and health characteristics. Methods: Data were derived from the fifth Korean National Health and Nutrition Examination Survey (KNHANES V-2, 2011). The subjects were 1,464 elderly aged 65 years or more (620 male and 844 female). The SPSS/WIN 21.0 program was used for data analysis. Results: Suicidal ideation was positively associated with depression and stress in both male and female subjects. For elderly men, those aged 75 years or more, had no spouse, and had activity limitations showed a higher suicidal ideation risk. For elderly women, those who had low a education level and were perceived to be unhealthy showed a higher suicidal ideation risk. Conclusion: Nurses should consider sex differences when designing suicide prevention programs for the elderly.

This study attempted to test the path model that can predict Korean adult suicidal ideation. The subjects were 459 adults aged between 19 and 64 who agreed to this study among quota sampled by the population, sex, and region of the metropolitan city. The path model of collected data was estimated using SPSS 24.0 program and AMOS 22.0. The results of the bias-corrected percentile method for verifying the significance of the mediator effect of the final model showed that suicidal attitude, depression, and stress were found to be mediating effects of health status on suicidal ideation. Suicide attitude and stress were found to mediate the effects of health status on depression. And the effect of drinking on depression was mediated by stress. This result is expected to be used as a practical basis for the development of suicide prevention and intervention programs for adults in the future.

The necessity for the investigation of death occurred in military services has no differences to the death of civilians. But the death of military service members under the Universal Conscription System in Korea has special considerations because of hard accessibility by the bereaved family and closed environment of the army. The analysis of the death occurred during military service was carried out and the advanced death investigation system to prevent the death was proposed to prevent the declination of fighting spirit and efficiency and also to restore the solid support by the people. The deaths in the period 1995~2006 were 330 persons in 1995, 359 persons in 1996 and were decreased to 135 persons in 2006. The death caused by safety accidents including vehicle accident, drowning, fall were 56% and by military crimes including suicide, arms, homicide were 44%. The numbers of suicides were 108 persons in 1995 and were decreased to 79 persons in 2006. The numbers of suicides were decreased constantly, but the ratio of suicide to death were increased, so the suicide prevention is more important. The autopsy ratio was increased to 51.5% in 2005 and was much higher compared to the ratio for civilians. The main reasons of complaints by the bereaved family were for regaining reputation, death in harness and reinvestigation of death. The proposals for the advanced death investigation system were as follows. The unnatural deaths including the obvious accidental deaths and homicides have to be defined by the rules. The human resources to perform the autopsy can be supported by the forensic pathologists from medical school. The special training and quality assurance programs are needed for the crime scene investigator. To regain the impaired reputation from the suicide and to support the bereaved family has to be discussed by the government.

Background Rosenthal et al. classified female, habitual, non-suicidal wrist cutters as a group and introduced the concept of wrist-cutting syndrome. We investigated the characteristics of wrist-cutting patients at our institution in comparison with results reported previously. Methods We conducted a retrospective study involving 115 patients who had cut their wrists and been examined at the emergency department of a single hospital in Seoul, Korea, between March 2014 and August 2018. Results There were more women (73 patients; 63.5%) than men (42 patients; 36.5%), and the women (mean age, 34.42 years) were significantly younger than the men (mean age, 50.07 years). The patients who had cut their wrists repeatedly were mainly women (22 of 26 patients; 84.6%); however, men caused more severe damage than women. Substance use before a suicide attempt did not significantly increase the severity of wrist cutting. Our institution planned and implemented a suicide prevention intervention program to improve the continuity of outpatient care. The number of patients who continued psychiatric treatment increased significantly after program completion. Conclusions We confirmed that most patients were young women who were not suicidal in the true sense because their wounds were not severe. Our study showed a protective role of the barrier tendons (flexor carpi radialis, palmaris longus, flexor carpi ulnaris), and we suggest careful repair of the barrier tendons to protect neurovascular structures against subsequent cutting events. We found that it was possible to improve the continuity of patient counseling by managing patients through a psychiatric treatment program.

In the age of low fertility and aging society, youth suicide is not the problem of a certain class but it should be recognized as an urgent and important social problem to be solved by our society. We aim to support the training of youth gatekeeper who can acquire the right attitude and understanding of suicide for adolescents, detect premature suicide signs of peer friends and link them to specialized institutions. In this paper, we propose a scenario based learning program that is linked to the concrete situation that the young people can sympathize with and a serious educational game of visual novel type that encourages participation of youth. We expect that the proposed serious game will improve the accessibility of educational facilities and youths through smart devices.

A Convergence study was attempted to identify the effects of stress on Suicidal ideation and mediating effects of depression in the relationship. The study were 166 elderly's over 65 years at G city and period was from August 29 to September 9, 2018. Data were analyzed PASW 18.0 program. As a result, stress had a significant effect on depression in stage 1, stress had a significant effect on suicide ideation in stage 2, stress and depression of parameter were significant predictors in stage 3. The explanatory power of the two variables was 24.3% in stress, 26.8% for stress accompanied with depression, and the partial mediating effect of depression on the effect of stress on suicide ideation. Based on this study, it can be used as a basic data for reducing suicide ideation of the elderly and study is needed to develop suicide prevention programs.

In 2016, the number of suicides per 100,000 population in Korea was 24.6, which is the highest record of OECD countries. The number of suicide deaths increased with age. Elderly people have a higher risk of completed suicide than any other age group. The purpose of this study was to analyze the panel data of the Korean Welfare Panel Study to identify the factors affecting the suicide of Korean older people. This study analyzed the data of the 11th Korean Welfare Panel Study, which was constructed in 2016. The mean age of the participants was 75.55 years and 37% were man and 63% were women. The annual prevalence of suicidal ideation was 3.4%. The effects of depression(Exp(B)=1.113) and subjective health status((Exp(B)=.767) on suicidal ideation was statistically significant by stepwise logistic regression analysis(Nagelkerke $R^2=.248$). Therefore, for the effective application of suicide prevention program for the older people, assessment of subjective health status and depression screening should be preceded.

Purpose: The purpose of this study is to develop a model for predicting mental health risk among adolescents based on health behavior information by employing a hybrid machine learning method. Methods: The study analyzed data of 51,850 domestic middle and high school students from 2022 Youth Health Behavior Survey conducted by the Korea Disease Control and Prevention Agency. Firstly, mental health risk levels (stress perception, suicidal thoughts, suicide attempts, suicide plans, experiences of sadness and despair, loneliness, and generalized anxiety disorder) were classified using the k-mean unsupervised learning technique. Secondly, demographic factors (family economic status, gender, age), academic performance, physical health (body mass index, moderate-intensity exercise, subjective health perception, oral health perception), daily life habits (sleep time, wake-up time, smartphone use time, difficulty recovering from fatigue), eating habits (consumption of high-caffeine drinks, sweet drinks, late-night snacks), violence victimization, and deviance (drinking, smoking experience) data were input to develop a random forest model predicting mental health risk, using logistic and XGBoosting. The model and its prediction performance were compared. Results: First, the subjects were classified into two mental health groups using k-mean unsupervised learning, with the high mental health risk group constituting 26.45% of the total sample (13,712 adolescents). This mental health risk group included most of the adolescents who had made suicide plans (95.1%) or attempted suicide (96.7%). Second, the predictive performance of the random forest model for classifying mental health risk groups significantly outperformed that of the reference model (AUC=.94). Predictors of high importance were 'difficulty recovering from daytime fatigue' and 'subjective health perception'. Conclusion: Based on an understanding of adolescent health behavior information, it is possible to predict the mental health risk levels of adolescents and make interventions in advance.

Global climate change is becoming one of the greatest challenges facing humanity. This article proposes a psychological perspective of climate change adaptation. Climate change-related severe adverse weather events may trigger mental health problems, including increased post-traumatic stress disorder (PTSD), depression, anxiety, violence, and even suicide. Forced migration could be considered a coping method for dealing with weather events, but it may also pose a psychological threat. People respond to severe weather events in different ways based on their individual characteristics. Psychological risks from adverse weather events are mediated and moderated by these factors, which are influenced by personal cognition, affect, and motivation. Examinations from a psychological perspective, which have been neglected in the science of climate change thus far, may provide keys to successful adaptation and the prevention of serious psychological problems resulting from the experience of severe weather events. A new prevention strategy has been suggested for coping with climate threats through encouraging attitude change, establishing proactive support systems for vulnerable groups, establishing a PTSD network, and implementing a stress inoculation program.
