The rate of suicide is the 5th leading cause of death in Korea. Moreover, suicide is the 1st cause of death in from 2nd to 4th decade. In order to treat suicide attempters who have visited the emergency room and to prevent retries, it is necessary to understand the nature of the suicide and to take the right approach. Suicide is more than doubled in women, and retry rates are high among patients with a history of suicide. Suicidal means are throat, fall, gas poisoning, poisoning and drowning. All suicide attempters should suspect and treat cervical spine injury and airway management, and rapid hyperbaric oxygen therapy is recommended for carbon monoxide addicts. Interviewing a suicide attempter requires a sympathetic attitude and examines the underlying depression or adaptation disorders. Interdisciplinary care with mental health departments is necessary, and interventions in emergency roombased suicide attempt management work can be helpful to connect with the community.

지난 50여 년 동안 우리나라의 사망률 감소 패턴에 대한 탐색적 연구에 의하면 연령별 사망률이 모든 연령에서 감소했지만, 특정한 사망률이 개선되고 있는 패턴은 연령과 기간에 따라 다르다는 것을 알 수 있다. 여자가 남자보다 사망률 개선이 뚜렷하고 특히 시간이 지나면서 특정그룹에서의 사망률 개선이 두드러짐에 따라 전반적으로 사망 시간 추세에 구조적인 변화가 존재함을 확인하였다. 이에 본 연구에서는 우리나라 여자 사망률 자료를 이용하여 미래 사망률 예측을 위해 코호트 효과를 고려한 다양한 확률적 사망률 모형을 살펴보았다. 또한 분석 결과를 바탕으로 2067년까지 연령별 사망률과 예측기대수명을 작성하고 통계청(KOSIS)에서 제공하는 장래 연령별 사망률과 기대수명과 비교하였다. 자료이용기간에 따라 최적의 모형이 상이하나 적합력과 예측력을 전반적으로 고려했을 때 우리나라 여자 사망률은 코호트 효과를 고려한 PLAT 모형이 적절하다 볼 수 있을 것이다.

Previous studies on the vast increase in suicide mortality in Southeast Asia have indicated that suicide rates increase in parallel with a rise in unemployment or during periods of economic recession. This paper examines the effects of economic recession on suicidal rates amongst agriculture, fisheries, and forestry workers in Korea. Monthly time-series gross domestic product (GDP) data were linked with suicidal rates gathered from the cause of death records between1993-2008. Data were analyzed using generalized additive models to analyze trends, while a polynomial lag model was used to assess the unconstrained time lag effects of changes in GDP on suicidal rate. We found that there were significant inverse correlations between changes in GDP and suicide for a time lag of one to four months after the occurrence of economic event. Furthermore, it was evident that the overall relative risks of suicide were high enough to bring about social concern.

본 연구는 일반인들 가운데에서 죽음을 어떻게 인식하고 있느냐에 따라 삶의 태도나 방식이 달라지기 때문에 행복에 따른 죽음인식에 차이가 있는지 알아보고, 행복지수가 높은 그룹과 행복지수가 낮은 그룹간의 호스피스 관심이 차이가 있는지 연구하고자 한다. 2017년 4월 22일 D 광역시에서 열린 걷기대회 행사에 참가한 20세 이상 성인 남녀 200명을 대상으로 설문조사를 실시하였다. 설문구성은 일반적 특성이 성별, 연령, 학력, 직업, 결혼상태, 가족 동거여부, 종교, 건강상태 8항목이었다. 행복에 관한문항은 총 29항목, 죽음 인식은 9항목으로 구성하였다. 통계 검정법으로는 설문지의 항목에 대하여 행복지수를 기준으로 카이제곱 검정, 독립표본 t-검정, 상관분석, 정준상관분석을 실시하였다. 연구결과, 임종하기 적합한 장소에 관한 문항에서 행복지수가 낮은 그룹은 "의료기관"이 46.3%로 가장 높았으며, 행복지수가 높은 그룹에서는 "살던 집"이 59.4%로 가장 높게 나타나 유의한 차이를 보였다. 병원에서 임종하는 경우가 훨씬 많은 우리나라의 현실에서 환자들이 원하는 편안하고 익숙한 장소인 집에서 임종을 맞이할 수 있는 방법인 가정형 호스피스의 이용률을 높일 수 있도록 전문 인력의 확보 및 교육 등 관리체계를 보완해야 할 것이라고 보여 진다. 그리고 대상자의 일반적 특성을 고려한 개별적이고 다양한 접근을 통하여 죽음인식을 높이고 호스피스를 효과적으로 이용할 수 있도록 하여야 할 것으로 사료된다.

The incidence and mortality rates of liver and nasopharyngeal cancer in Guangxi province of China have always been among the highest in the world, and cancer is one of the major diseases that pose a threat to the health of residents in Guangxi. However, no systematic study has been performed to evaluate the time trends in the structure of cancer-related deaths and cancer mortality. In this study, we reveal sex, age and geography differences of cancers mortality between three death surveys (1971 to 1973, 1990 to 1992, and 2004 to 2005). The results show that the standardized mortality rate of cancer in Guangxi residents has risen from 43.3/100,000 to 84.2/100,000, the share of cancer deaths in all-cause deaths has increased from 13.3% to 20.7%, and cancer has become the second most common cause of death. The five major cancers, liver cancer, lung cancer, gastric cancer, nasopharyngeal cancer and colorectal cancer, account for 60% of all the cancer deaths. Cancers with growing mortality rates over the past 30 years include lung cancer, colorectal cancer, liver cancer and female breast cancer, of which lung cancer is associated with the sharpest rise in mortality, with a more than 600% rise in both men and women. Cancer death in Guangxi residents occurs mainly in the elderly population above 45 years of age, especially in people over the age of 65. The areas with the highest mortality rates for liver cancer and nasopharyngeal cancer, which feature regional high incidences, include Chongzuo and Wuzhou. Therefore, for major cancers such as liver cancer, lung cancer, gastric cancer, nasopharyngeal cancer and female breast cancer in Guangxi, we can select high-risk age groups as the target population for cancer prevention and control efforts in high-prevalence areas in a bid to achieve the ultimate goal of lowering cancer mortality in Guangxi.

Background: Prostate cancer (PC) is one of the leading causes of death, especially in developed countries. The human development index (HDI) and its dimensions seem correlated with incidence and mortality rates of PC. This study aimed to assess the association of the specific components of HDI (life expectancy at birth, education, gross national income per 1000 capita, health, and living standards) with burden indicators of PC worldwide. Materials and Methods: Information of the incidence and mortality rates of PC was obtained from the GLOBOCAN cancer project in year 2012 and data about the HDI 2013 were obtained from the World Bank database. The correlation between incidence, mortality rates, and the HDI parameters were assessed using STATA software. Results: A significant inequality of PC incidence rates was observed according to concentration indexes=0.25 with 95% CI (0.22, 0.34) and a negative mortality concentration index of -0.04 with 95% CI (-0.09, 0.01) was observed. Conclusions: A positive significant correlation was detected between the incidence rates of PC and the HDI and its dimensions including life expectancy at birth, education, income, urbanization level and obesity. However, there was a negative significant correlation between the standardized mortality rates and the life expectancy, income and HDI.

A total of 167 patients underwent mascroscopic vasovasostomy by a modified double layer reanastomosis to correct postvasectomy sterility during a 5-year period between 1986 and 1991. We obtained the anatomical patency and pregnancy rates from 61 patients whose follow-ups were completed. There by, we report the following results. 1. Of the 167 patients, the mean age and the average duration of vasobstruction were 34.0 and 4. 4 years respectively. The reasons for ecanalization were desire for more baby in 71.9%. death of children, 24.5% and remarriage in 3.6%. 2. Of the 61 patients with complete follow-up. the anatomical patency and pregnancy rates were 83.6%(51 patients) and 50.8%(31 patients) respectively. 3. For the 36 out of 61 patients whose duration of vasobstruction was less than 5 years, the anatomical patency and pregnancy rates were 88.9%(32 patients) and 58.3%(21 patients) respectively. The rates for the remaining 25 patients whose duration was greater than 5 years were 80.0%(20 patients) and 40.0%(10 patients). 4. Of the 61 patients, 51 exhibited sperms from the proximal vas on microscope during the operation. Their anatomical patency and pregnancy rates were 88.2%(45) and 54.9%(28) respectively. The rates for the remaining 10 patients without any sperms were 60.0%(6) and 30.0%(3). From the above results, we can conclude that macroscopic reanastomoses by modified double layer technique has appreciable success rates that could possibly be compared to the microscopic results.

This study was to evaluate hospital characteristics as composition of manpower and facilities to the death rate of patient; and to earmark the factors affecting the overall hospital mortality rates. The data utilized were derived from survey material conducted by the Korean Hospital Association on 32 tertiary referral hospitals in Korea between 1986 and 1994. The findings are : 1. Those hospitals having the most capacity per bed had little difference to the mortality rates than the others. 2. Those hospitals having the most daily patients per specialist had significantly higher mortality rates than the others, but the number of daily patients per nurse had little effect on the mortality rates. 3. Those hospitals which had a relatively sufficient number of quality assurance activities revealed a lower mortality, and particularly in case where such effort was directed to the clinicians, the outcome was remarkable. We concluded that the major factor affecting the hospital mortality rates seems to be the number of specialists per number of beds, the degree of quality assurance assessment of the clinicians, the quality assurance activities of each hospital as a whole, and the number of daily patient per specialist. According to the findings of this study, the composition and quality of specialist and adequate quality assurance activities seemed to be the essential for the improvement of hospital care. Therefore, in this regard e proper implementation of policy and support is highly recommended. Due to lack of available research material, the personal characteristics of specialists haven't been considered in this study. However, this longitudinal observation of 32 tertiary referral hospitals over a nine year period has significant merit alone.

Objectives : This study aimed to calculate the survival rates of cancer patients in Jeju Island residents from 2000 to 2001, based on their major primary sites of occurrence. Methods : Data were extracted from the database of the Jejudo Cancer Registry (JCR). The eligible population comprised 2,382 cancer cases, whose cancers were diagnosed from 1 January 2000 through 31 December 2001. Of the eligible population, 1,438 patients with 5 major cancers defined by the level of incidence rates were selected as the study participants. The period of survival for each case was calculated from the date of first diagnosis to the date of death, or the end of follow-up, i.e., 31 December 2003. The observed survival rates (OSR) and relative survival rates (RSR) were calculated according to sex, age-group, and primary sites of occurrence. Results : The 3-year OSR and RSR in 5 major cancers were higher in women than in men except 75 year-old over group. The 3-year RSR of stomach, colorectum, liver, and lung in both sexes were 61.0%, 62.6%, 24.7%, and 22.8%, respectively. The respective rates in JCR showed some statistically significant differences from those in the Korea Central Cancer Registry (KCCR). Conclusions : These results would suggest some clues about prognostic factors of major cancers in Korean, and could apply to planning and evaluating of cancer control strategies in Jeju Island.

Objectives: Due to their developmental characteristics, adolescents have a higher probability than other age groups of experiencing injuries caused by accidents, violence, and intentional self-harm. The severity and characteristics of injuries vary by the intentionality and mechanism of injury; therefore, there is a need for a national-level estimate of the scale and the severity of injuries in adolescents that takes these factors into account. Methods: By using data from the Emergency Department-based Injury In-depth Surveillance Data, National Emergency Department Information System, the Korean National Hospital Discharge In-depth Injury Survey, and cause of death statistics, we calculated the emergency department (ED) visit rate, hospitalization rate, and death rate of injuries per 100 000 adolescents for each injury mechanism. The calculated rates were used to generate the injury pyramid ratio (ratio of death rate to hospitalization rate to ED visit rate) to visualize the scale and the severity of the injury. Results: The mortality rate in adolescents due to injury was 10/100 000; the corresponding rates for hospitalization and ED visits were 1623 and 4923, respectively, resulting in an injury pyramid ratio with the general pyramid form, with a 1:162:492 ratio of deaths to hospitalizations to ED visits. The mortality rate due to suicide/intentional self-harm was 5/100 000, while 35 were hospitalized for this reason and 74 made ED visits. The pyramid ratio of 1:7:15 for intentional self-harm/suicide showed a steep pyramidal form, indicating considerable lethality. The mortality rate due to motor vehicle collisions (MVCs) was 3/100 000; 586 were hospitalized for this reason, while 1023 made ED visits. The pyramid ratio of 1:195:341 for MVCs showed a gradual pyramid form, indicating that the lethality was low and the scale of injury was high. Conclusions: The main categories of injuries in adolescents were visualized in pyramid form, contributing to an understanding of the scale of each injury by mechanism in terms of levels of death, hospitalization, and ED visits. These findings will be helpful for understanding how to prioritize injuries in adolescents.
