Suicides have been considered to be one of the grave problems of modern societies. According to recent police statistics of Republic of Korea, 28.6 suicides in every 100, 000 were reported. Psychiatric Patients are believed to be predisposed to suicidal tendencies. This study was performed to investigate the characteristics of suicidal attempts and to analyse the environmental factors involved in the suicidal accidents of patients admitted to psychiatric hospitals. Records of 66 suicidal accidents from three psychiatric hospitals during the period of January 1971 through June 1971 were sampled. Data were analysed by percentile score. Results are as follows; 1. The age group of 21~30yrs. was revealed to be the highest in frequency of suicidal attempts (50.0%) Among the unsuccessful suicides; the age group of 31~40yrs. in men and the age group of 21~30 yrs. in women revealed to be the highest in frequency-Among the unsuccessful suicides; the age group of 21-30 yrs. in both sex revealed to be the highest in frequency. 2. Suicidal accidents occurred more frequently to the unmarried(63.6%)- Among the successful suicides; higher frequency was shown to unmarried in men and the frequency is contrasted in women. Among the unsuccessful; the unmarried in both sex were revealed to be highest in frequency. 3. Schizophrenia was revealed the highest of suicidal attempts in frequency (81.8%). 4, Suicides were most frequently attempted in the spring(46, 9%). Among the successful suicides; highest frequencies were shown in men in tile winter and in women in the summer season. Among the unsuccessful suicides :highest frequencies were shown in men in the winter and in women in the spring. 5. Suicidal attempts were most frequently occurred in hospital wards (40.9%), In women, unsuccessful attempts were found to be the highest on authorized leave at their homes. 6. The hanging was revealed to be the most frequently adopted methods for suicidal attempts (31.8%). Among the successful suicides; hanging was the most frequent method adopted in men white in women the drug over-dose, Among the unsuccessful suicides ; stabbing by sharp devices while in women drug-overdosage was adopted as well 7. The most frequently adopted instrument of different suicidal attempts were: house-hold wrapper (26.3%) in cases of hanging, knives (31.8%) in cases of stabbing, and drugs. 8. The suicidal attempts have occurred most frequently at dawn through early morning (2-6A. M.) (34.8%). Among the successful suicides i most frequent time of occurrence on week-days were revealed to be dawn, while on holidays the occurrence were in the evening as well Among the unsuccessful; the most frequent time of occurrence was the day hours while on holidays at dawn. 9. Suicidal attempts within the hospital ward were first noticed by nurses most frequently (42.2%). 10. Manifestations such as restlessness, depression, self-depreciation were revealed to be the most frequent pre-suicidal attempt behavior characteristics. 11. Among the successful suicides ; manifestations of physical damage were found on the neck while among unsuccessful attempts, the damages were found on exterminates.

Objectives: The purpose of the present study was to explore the relationships between views on suicide, death, and life and lifetime suicidal attempts in the Korean context. Methods: Multiple logistic regression model was tested using data from Korean General Social Survey of 2009. We utilized the nationally representative survey data obtained via multistage stratified area probability sampling design from 1,599 respondents aged ${\geq}18$ years. Results: The proportion of lifetime suicidal attempts was 12.1% of entire sample in Korea. Some components of views on suicide and death influenced significantly on lifetime suicidal attempts after adjusting for demographic and health-related factors. The positive view on suicide(OR=0.76, 95% CI: 0.62-0.94), the naturalistic view on afterlife(OR=0.37, 95% CI: 0.67-0.99) and death concern(OR=0.67, 95% CI: 0.55-0.83) were risk factors of lifetime suicidal attempts. In contrast, the social responsibility view on suicide(OR=1.17, 95% CI: 1.00-1.37) and the transcendental view on afterlife(OR=1.25, 95% CI: 1.02-1.54) lowered the risk. Conclusions: Practical implications of the findings were discussed exploring policy evidences to screen high risk groups out and to reframe educational programs for suicide prevention. Strategic health messages need to be developed and transmitted for prevention of suicide.

Objectives:Recently, polymorphisms of several serotonin genes have been suggested to be associated with suicide, but the results are still unclear. We examined whether the T102C polymorphisms of the serotonin 2A receptor gene and the G861C polymorphisms of the serotonin 1B receptor gene were associated with suicidal behavior using drug intoxication. Methods:The subjects were 52 patients who visited emergency room with suicidal behaviors. Fifty controls were selected from healthy volunteers matched for sex and age to the suicide subjects. The polymorphisms were analyzed with TaqMan$^{(R)}$ assay using primers based on previous studies. Results:The T102C polymorphism of the serotonin 2A receptor gene showed no significant difference between the suicidal attempters and controls in both genotype and allele frequency analyses(p=0.179 and p=0.422, respectively). There was no statistically significant difference between the suicidal attempters and the controls in the G861C polymorphism of the serotonin 1B receptor gene and any significant effect of the genotype distributions or the allele frequencies was not observed(p=0.092 and p=0.987, respectively). Conclusion:These findings suggest that the T102C polymorphism in serotonin 2A receptor gene and the G861C polymorphism in serotonin 1B receptor gene are not related to the susceptibility to suicide attempts using drugs. To clarify the genetic influences of the serotonergic system on suicidal behavior, the polymorphisms of other candidate genes in the serotonergic system should be studied with larger numbers of subjects.

Suicide is a behavior that is intended to cause death by itself and requires medical treatment, resulting in suicidal attempt or completion. Suicide causes loss of life, damages the body, costs a lot of medical expenses, and causes families to fall into sorrow and suffering therefore this suicide is a huge loss to family and society. There have been attempts to reduce and prevent suicide by understanding the mechanism of suicide. The mechanism of suicide can be thought of as psychological mechanism and biological mechanism. In the past, if we considered the psychological and biological mechanisms separately, the development of neuroscience now connects and integrates these two. Psychological factors affect biological factors and biological temperaments also affect perception or thinking about the situation and increase psychological vulnerability. Distant factors in suicidal behavior-such as childhood adversity and family and genetic predisposition-increase the lifetime risk of suicide. They alter the response to stress and other processes through changes in gene expression and regulation of emotional and behavioral characteristics. Distant factors affect the biological system and consequently changes in these systems can increase the risk of suicide. In other words, the distal factor does not directly induce suicidal behavior but rather acts indirectly through developmental or mediating factors. These mediating factors are impulsive aggressive and anxious trait, and chronic use of substances. The mechanism of this disorder is the abnormality of the serotonin system and the abnormality of the lipid level. Proximal factors are associated with the onset of suicide events and include changes in the major neurotransmitter systems, inflammatory changes, and dysfunction of glial cells in the brain. A series of studies, including a variety of research methods and postmortem and in-vivo imaging studies, show the impairment of the serotonergic neurotransmitter system and hypothalamic-pituitary-adrenal axis stress response system for suicidal behavior. These disorders lead to suicidal behavior due to difficulty in cognitive control of mood, pessimism, reactive aggression, abnormality in problem solving abilities, excessive response to negative social signals, severe emotional distress, and cognitive dysregulation of suicidal ideation.

Objectives : Severe mental illness is a major risk factor for suicide. This study aimed to identify characteristics of patients who died by suicide among subjects who had been received service from a community mental health center. Methods : We searched individuals who had committed suicide in Gwangju Bukgu Community Mental Health Center since 2006. Sociodemographic and clinical data were gathered from medical records and their case managers and they were compared with those of general members in the center. Characteristics of schizophrenia patients who died by suicide were particularly summarized. Results : Twelve person committed suicide between 2006 and 2016. The characteristics of those who died by suicide were male (67%), diagnosis of schizophrenia (75%), aged below 50 (83%), unemployed (92%), past history of psychiatric hospitalization (100%), recent admission within 3 months (67%), past history of suicidal attempt (78%), family history of schizophrenia (58%), poor adherence to medication (58%), and use of daily rehabilitation program (42%). Ten out of twelve (83%) showed warning sign for suicide. All identified method of suicide in patients with schizophrenia was jumping from high building. Many patients with schizophrenia, who committed suicide, suffered from comorbid depressive symptoms (67%) and auditory hallucination (78%). Conclusion : Case managers should pay attention to and carefully manage individuals who showed suicidal warning, particularly with risk factors for suicide, such as unemployment, admission state or recent discharge from psychiatric hospital, poor adherence to medication, family history of schizophrenia, and a history of suicidal attempt.

본 연구의 목적은 자살에 영향을 미칠 수 있는 일반적 특성들과 동시에 체질량지수(Body Mass Index, BMI)를 통제함으로써 체형지수(A Body Shape Index, ABSI)가 자살생각과 자살시도와 어떠한 관련성이 있는지에 대해 알아보는 것이다. 2013년부터 2015년까지 질병관리본부의 제 6기 국민건강영양조사 자료를 이용하였으며, 자살행동에 영향을 미칠 수 있는 변수들에 대한 정보가 없는 자들을 대상에서 제외한 총 13,155명을 대상으로 카이제곱검정과 다변량 로지스틱회귀분석을 실시하였다. 분석 결과는 BMI에서 '비만'에 해당하는 자들이 BMI에서 '표준'에 해당하는 자들보다 자살생각과 자살시도가 높았고, ABSI에서는 Q3에 해당하는 그룹이 Q1에 해당하는 그룹에 비해 자살생각이 높았다. 자살시도는 ABSI에서 Q3에 해당하는 그룹이 Q1 그룹에 비해 3.623배(95% CI 1.027-12.772) 높았으며 유의한 결과를 보였다. 본 연구의 결과는 BMI와 비교하여 ABSI가 높이 나타나면 단순히 자살생각보다는 자살시도라는 더욱 극단적인 선택을 할 수 있음을 의미하는 것으로 우리사회는 ABSI가 높은 자에 대해 사회적인 관심과 적절한 관리를 할 수 있도록 해야 할 것이다.
