Objectives: Hanging is a common method of attempted suicide. This study investigated the epidemiological profile of attempted and completed suicides by hanging in southern Iran. Methods: This cross-sectional study was performed on 1167 suicide attempts by hanging between 2011 and 2019. All data related to suicide attempts by hanging were collected from the Fars Suicide Surveillance System. The trends in suicide cases and the mean age of attempted and completed suicides were plotted. The chi-square test was used to identify suicide-related factors. Crude rates of incidence, mortality, and standardized fatality during the study period were calculated. Finally, logistic regression was used to identify the predictors of death in individuals who attempted suicide. Results: The mean age of those who attempted suicide was 33.21±16.82 years; the majority were male (80.5%). The rate of attempted and completed suicide by hanging were 3.50 and 2.79 per 100 000 people, respectively. The case-fatality rate was calculated as 79.34%. The results of our study indicated an increasing trend in suicide attempts by hanging. The likelihood of death was 2.28 times higher in individuals with a previous history of suicide attempts and 1.85 times higher in those with a psychological disorder. Conclusions: The findings of this study suggest an increasing trend in attempted and completed suicide by hanging, especially among individuals with a history of suicide attempts and psychological disorders. It is necessary to take action to reduce the rate of suicide attempts and identify the underlying causes of suicide attempts by hanging.

Background: Due to an increasing number of workers aged 50 years and above, the number of those employed is also on the rise, and those workers aged 50 and over has exceeded 50% of the total fatal occupational injuries. Therefore, it is necessary to implement the selection and concentration by identifying the characteristics of high-risk groups necessary for an effective prevention against and reduction of fatal occupational injuries. Methods: This study analyzed the characteristics of high-risk groups and the occupational injury fatality rate per 10,000 workers among the workers aged 50 and over through a multi-dimensional analysis by sex, employment status of workers, industry and occupation by targeting 4,079 persons who died in fatal occupational injuries from January 2007 to December 12. Results: The share of the workers aged 50 years and above is increasing every year in the total fatal occupational injuries occurrence, and the high-risk groups include 'male workers' by sex, 'daily workers' by worker's status, 'craft and related-trades workers' by occupation, and 'mining' by industry. Conclusion: The most frequent causal objects of fatal occupational injuries of the workers aged 50 years and above are found out to be 'installment and dismantlement of temporary equipment and material on work platforms including scaffold' in the construction industry and 'mobile crane, conveyor belt and fork lifts' in the manufacturing industry.

Purpose: There has been no nationwide surveillance survey of poisoning cases in Korea. This study examined the clinical characteristics of poisoning admissions in order to obtain preliminary data for future planning. Methods: This study retrospectively reviewed the data on poisoning admissions of 150 hospitals based on the hospital discharge injury surveillance data of Center for Disease Control and Prevention in Korea from January to December in 2004. The demographic data, poisons used, causes of poisoning, reasons for attempted suicide and mortality rate was investigated according to the age group. The factors associated with mortality were also evaluated. Results: A total 836 patients admitted for poisoning were analyzed. Their mean age was $46.5{\pm}19.5$ years (male 415, female 421). The most frequent age group was the 4th and 5th decades. The most common poisons involved were pesticides (45%) and medications (23%). The majority (64%) involved intentional poisoning except for those in the 1st decade. The most common reason for the attempted suicide was family problems. However, individual disease was the most common reason in those over 60 years. The overall mortality rate was 8.7% (73/836). Pesticides and being elderly (over 65 years old) were strongly correlated with fatality. Conclusion: The incidence of intentional poisoning increases from the 2nd decade making it a preventable injury. "Overall, the incidence of intentional poisoning increases from the 2nd decade". Therefore, there is a need to frame a prevention policy corresponding to each factor related to fatality, such as an elderly population and pesticides.

To estimate the incidence rate of coronary heart disease in Korea, of all residents in Taegu city aged 25 or above, those who had an acute MI or a fatal coronary event between 1 July 1996 and 30 June 1997 were registered. Seven hundreds and eight patients were registered during the study period(685 were identified at hospital and 23 were autopsy cases). Age-standardized annual incidence rate of men in city area was 93 per 100,000(95% CI; 61-142) and 35% CI; 16-67) in women(100 in men and 20 in women aged 35-64). The incidence was rapidly increased after age 40 in men, however, in women after age 60. Twenty-eight-days case fatality rate was 45% in men and 47% in women. However, in the age group of 45-59 case fatality rate in women was two times higher than that in men. In conclusion, crude annual incidence rate of CHD in city area was 73 per 100,000 in men and 33 in women. The age-standardized annual incidence of CHD in men(93 per 100,000) was 2 times higher than that in women (33 per 100,000) in Korea.

연구배경: 국가 결핵관리 체계내의 결핵환자중에서 만성 배균 환자로 판정받은 환자들의 치명률, 생존률, 균음전률 등을 관찰하기 위하여 본 조사를 실시하였다. 방법: 강원도내의 22개 보건소에 등록하여 치료를 받은 환자중에서 1987년 초부터 1992년 말까지의 6년 동안에 재치료실패로 판정받은 환자들을 대상으로 하였다. 대상자들중 조사시점(93년 10월~11월)까지 생존해 있는 경우는 3회의 객담도말 검사와 배양을 실시하여 균의 배출여부를 조사하였다. 이미 사망한 경우는 보관된 자료에 근거하여 사망일시 및 원인을 조사하였다. 또한 대상자 모두 재치료 실패로 판정받은 이후의 치료력과 균음전여부도 조사하였다. 결과: 1) 성별분포를 보면 약 4.2:1의 비율로 남자에서 높았으며, 1990년도 우리나라 실태조사에서 밝혀진 성별 비율과 비교해보면 약 1.6배로 난치성환자로 될 위험성이 남자에서 높음을 보여주었다. 2) 보건소 내소 당시의 흉부 엑스선 사진을 보면, 이미 대상자의 94.6% 정도가 중등증이상으로 병변이 진행된 상태임을 보여주었다. 3) 누적결핵치명률은 1년에 19.74%, 2년 26.81%, 3년 31.16%, 4년 34.55%로 증가하다가 그후부터는 거의 증가하지않는 모습을 보여주었다. 4) 생존률을 보면, 1년에 만성 배균자의 80.26%가 생존하고, 그후 4년까지 생존률이 65.45%로 감소하지만 그후는 거의 변함이 없음을 보여 주었다. 결론: 만성 배균 난치성 폐결핵 환자로 진행되는 위험성이 남자에서 높았고, 내소당시 중등증이상으로 폐가 손상되었던 환자가 대부분이었다. 5년동안에 1/3 정도가 사망하였으며, 약 2/3는 균양성인채로 생존하고 있었다. 이것은 치료받지 않은 결핵환자들의 자연적인 운명과 비교할 때, 결핵치명률은 낮고 생존률은 높았다. 치료처방이 개선되면서 난치성 환자의 수가 줄어드는 추세이지만, 향후 계속적으로 난치성 환자를 줄여나가기 위해서는 전반적인 환자관리의 질적인 향상에 관심을 기울여야할 시점이다.

Objective : The case fatality rate of nonlesional intracerebral hemorrhage (n-ICH) was high and not changed. Knowing the causes is important to their prevention; however, the reasons have not been studied. The aims of this study were to determine the cause of death, to improve the clinical outcomes. Methods : We retrospectively analyzed consecutive cases of nonlesional intracerebral hemorrhage in a prospective stroke registry from January 2010 to December 2010. Results : Among 174 patients ($61.83{\pm}13.36$, 28-90 years), 29 patients (16.7%) died during hospitalization. Most common cause of death was initial neurological damage (41.4%, 12/29). Seventeen patients who survived the initial damage may then develop various potentially fatal complications. Except for death due to the initial neurological sequelae, death associated with immobilization (such as pneumonia or thromboembolic complication) was the most common in eight cases (8/17, 47.1%). However, death due to early rebleeding was not common and occurred in only 2 cases (2/17, 11.8%). Age, initial Glasgow Coma Scale, and diabetes mellitus were statistically significant factors influencing mortality (p<0.05). Conclusion : Mortality of n-ICH is still high. Initial neurological damage is the most important factor; however, non-neurological medical complications are a large part of case fatality. Most cases of death of patients who survived from the first bleeding were due to complications of immobilization. These findings have implications for clinical practice and planning of clinical trials. In addition, future conduct of a randomized study will be necessary in order to evaluate the benefits of early mobilization for prevention of immobilization related complications.

In this study, the current regulations to be adequate in industrial site have to be renew in order to prevent the fatal injuries by mobile cranes. Fatal injury analyses were conducted with several accident cases by the mobile cranes. For each accident, the causes of the injuries were examined and proper safety measures were proposed. This study proposed a revision of the standard guideline as an accident prevention measures through in-depth analysis of fatal accidents. First, fatality rate per 10,000 persons by the mobiles cranes was 0.57 in 2011. Second, the in-depth analysis of the mobile crane accidents showed that the main factors of the accidents were the overturn of mobile crane, the fracture of connection part between mobile crane boom and rope, the breaking of rope and the misunderstanding over the signal between a mobile crane driver and workers around a mobile crane. Third, the order of high defection of connecting parts was bucket bolt, bracket and extension parts. Fourth, since there were several cases of overturn of mobile crane by itself in the in-depth analysis of the mobile crane, the over slop-proof device was proposed as the main alternative in this study. Fifth, the revision of standards of safety factor that shall be more than 10, of connecting parts of mobile crane was proposed.

The authors collected epidemiological and clinical informations on 1,307 CO patients from the questionairefilled by attendants of patients and from the clinical records kept in the hospital. All patients were treated by hyperbaric oxygenation at the Hyperbaric Chamber Unit of Seoul National University Hospital during 5 years, from January, 1969 to December, 1973. The following findings were obtained. 1. Female showed higher incidence rate than male. The highest incidence rate was observed in the age group of 15-29 years in both sex. 2. The most important variable influencing the recovery of the patients was the starting time of treatment. It was evident that earlier the starting time, shorter the recovery time. 3. Duration of admission was within 5 days in 57.1 percent of the admitted cases and 76.1 percent of them was discharged within 8 days. 4. As the complications, pulmonary edema, bronchopneumonia and trophic changes were observed. Also the neurological disorders were found. 5. The fatality rate followed by the hyperbaric oxygenation was 1.07 percent.
