Objectives: The objective of this paper is to study influence of self esteem, family support and adaptation to school life on adolscents' suicidal ideation adjsuted for general characteristics effect. Methods: Using cluster sampling, 318 high school freshmen from T city were extracted as survey subjects. Independent t-test, ANOVA, Duncan test, Pearson's correlation coefficients and multiple regression analysis were applied for statistical analysis. Results: Among general characteristics, religion, family income, single-parentedness, health status and school grades were statistically significant with suicidal ideation. Controlling the above variables, increase in self-esteem (${\beta}$=-.300) and family support (${\beta}$=-.267) showed statistically significant decrease in suicidal ideation but adaptation to school life did not. Conclusions: Therefore, it is proposed that measures for enhancement of self esteem and family support to be included in development of suicide prevention programs.

Objectives : Among adolescents, the proportion of daily smoking tends to increase with age, and does not return to the previous level. Therefore, we examined the factors associated with smoking frequency in a nationwide sample of Korean adolescents to help prevent the progression of smoking. Methods : Among 127,804 adolescents who participated in the 2016 and 2017 Korean Youth Risk Behavior Web-Based Survey, data from 7,781 adolescents who replied that they currently smoked were analyzed. According to the frequency of cigarette smoking, participants were classified into daily and non-daily smokers. Participants' socio-demographic characteristics, smoking behavior, and psychological problems including perceived stress, depressive mood, and suicidality were assessed. Results : There were 3,627(47.4%) daily smokers and 4,154(52.6%) non-daily smokers. Low parental educational level, and early smoking experience were positively associated with daily smoking. High academic achievement, and high socio-economic status were negatively associated with daily smoking. Daily smoking was positively associated with lower happiness, lower sleep satisfaction, and severe stress during the past 12 months. Factors affecting suicide attempts of smokers were sex, residential type, socioeconomic status, and early smoking experience. Conclusion : The results indicated that socially disadvantaged families, and smoking experience with young age influenced daily smoking among Korean adolescents. Daily smoking was associated with psychological problems including lower happiness, lower sleep satisfaction, and severe stress. Early smoking experience influenced suicidal attempts among Korean adolescent smokers. Early intervention for smoking cessation in this high-risk group may contribute to prevention of these psychiatric complications of smoking.

Objectives: Non-suicidal self-injury (NSSI) and suicidal behavior, including suicidal ideation (SI) and suicide attempts, are important predictors of suicide in adolescents. This study aimed to investigate the associations between NSSI, SI, NSSI+SI, mental health problems, and family factors in Korean adolescents in Jeju Island, with an emphasis on key findings. Methods: A total of 561 adolescents completed self-report questionnaires regarding demographics, NSSI, SI, suicidal behavior, perceived family functioning, and mental health problems, which were assessed using Center for Epidemiological Studies Depression Scale for Children, Screen for Children Anxiety-Related Disorders (SCARED), and Youth Self-Report (YSR). Data were analyzed using descriptive statistics, one-way analysis of variance, chi-square test, post-hoc analyses, and multivariate logistic regression. Results: In this study, 22.3% of adolescents reported either NSSI or SI, with 5.5% reporting NSSI and 20.7% reporting SI. Combined (NSSI+SI) group showed a significantly higher SCARED score, anxiety/depression, thought problems, attention problem, and rule breaking on YSR than did the SI only group. Higher level of depression and anxiety were significantly associated with NSSI and SI. Female sex and perceived family dissatisfaction were significantly associated factors for SI, but not for NSSI in multivariate logistic regression. Conclusion: This study provides insights into the clinical characteristics and associated factors among adolescents with NSSI, SI, and NSSI+SI in Jeju Island. Identifying these results can inform the development of targeted prevention and intervention strategies to mitigate the negative consequences of these behaviors and contribute to a better understanding of the role of family in this context.

매년 20여명 정도의 경찰이 자살에 이르고 있다. 업무량이 많은 타 공무원에 비해서도 높은 수준이다. 경찰의 자살에는 여러가지 원인이 있지만, 특히 조직의 폐쇄성으로 인해 개인문제로 치부하는 경향이 높다. 경찰의 치안환경은 더욱 안 좋아지고, 위험성에 노출될 확률이 과거에 비해 높아졌으며, 잔혹한 범죄를 마주해야 하는 상황이 많아짐에 따라 우울증이나 업무부담 등으로 인해 자살을 하게되는 경우를 볼 수 있다. 따라서 경찰의 자살을 예방하기 위해서는 심리부검을 도입하는 방안을 법적으로 검도하고, 자살유형들을 분석하여 그에 맞는 자살예방모형 개발하여 자살률을 감소시킬 수 있는 방안을 모색해보고자 한다.

Purpose: The purpose of this study was to examine the prevalence and risk factors of suicidal ideation among middle class Korean. Methods: Cross sectional study was designed for secondary data analysis. From the 8th Korea Health Panel survey (2008~2013), a total of 6,037 data was drawn and analyzed by developmental stage using descriptive statistics including frequency, percentage, $x^2$ test, and logistic regression analysis. Results: Across all age groups, high physical-mental stress, frustration, anxiety about the future and low self-perceived health status or social class were found to be the risk factors of suicidal ideation. Peer-compared subjective health status and frustration significantly influenced the adolescents. The young adults'suicidal ideation was mainly influenced by physical and mental stress, frustration and absence of economic activity. For the middle-aged, physical and mental stress, frustration, future anxiety, low peer-compared subjective health status were found to be the major influencing factors. The predominant risk factors for the elderly were frustration and low peer-compared subjective health status. Conclusion: Making comparisons to others significantly influence suicidal ideation throughout all life cycles. Improvement of mental health and suicide prevention can be enhanced by avoiding negative comparison to others.

Purpose The purpose of this study is to develop a prediction model and decision rules for the elderly's suicidal ideation based on the Korean Welfare Panel survey data. By utilizing this data, we obtained many decision rules to predict the elderly's suicide ideation. Design/methodology/approach This study used classification analysis to derive decision rules to predict on the basis of decision tree technique. Weka 3.8 is used as the data mining tool in this study. The decision tree algorithm uses J48, also known as C4.5. In addition, 66.6% of the total data was divided into learning data and verification data. We considered all possible variables based on previous studies in predicting suicidal ideation of the elderly. Finally, 99 variables including the target variable were used. Classification analysis was performed by introducing sampling technique through backward elimination and data balancing. Findings As a result, there were significant differences between the data sets. The selected data sets have different, various decision tree and several rules. Based on the decision tree method, we derived the rules for suicide prevention. The decision tree derives not only the rules for the suicidal ideation of the depressed group, but also the rules for the suicidal ideation of the non-depressed group. In addition, in developing the predictive model, the problem of over-fitting due to the data imbalance phenomenon was directly identified through the application of data balancing. We could conclude that it is necessary to balance the data on the target variables in order to perform the correct classification analysis without over-fitting. In addition, although data balancing is applied, it is shown that performance is not inferior in prediction rate when compared with a biased prediction model.
