Backgrounds: Deaths from pesticides poisoning has increased annually, but no studies have been reported. Especially paraquat is suspected to be a major material in pesticide poisoning deaths. In Korea, simple epidemiology of pesticides poisoning is not well known. So, there is no effective method to prevent pesticides poisoning. We tried to investigate the present status of pesticides poisoning with data from Korea National Statistical Office and suggest an effective counterplan. Methods: We analysed death cause data derived from Korean Statistical association, deaths causes being pesticides poisoning in the year 2002. Also, we investigated data from internet, mainly from Korea National Statistical Office home page. Results: Total 2,875 persons died after pesticides poisoning in 2002 year. Average age is 54.2 year, standard deviation being 17.7 year. Many victims (about $41\%$) died during the herbicides' non-necessary period (JanuaryMarch, October-December) Conclusion: Herbicides sale should be restricted only during herbicides' necessary period, and so called a pesticides safety supervisor system shall effectively prevent herbicides poisoning.

Objectives: Many epidemiological studies have suggested that a variety of medical illnesses are associated with suicide. Investigating the time-varying pattern of medical care utilization prior to death in suicides motivated by physical illnesses would be helpful for developing suicide prevention programs for patients with physical illnesses. Methods: Suicides motivated by physical illnesses were identified by the investigator's note from the National Police Agency, which was linked to the data from the Health Insurance Review and Assessment. We investigated the time-varying patterns of medical care utilization during 1 year prior to suicide using repeated-measures data analysis after adjustment for age, gender, area of residence, and socioeconomic status. Results: Among 1994 suicides for physical illness, 1893 (94.9%) suicides contacted any medical care services and 445 (22.3%) suicides contacted mental health care during 1 year prior to suicide. The number of medical care visits and individual medical expenditures increased as the date of suicide approached (p<0.001). The number of medical care visits for psychiatric disorders prior to suicide significantly increased only in 40- to 64-year-old men (p=0.002), women <40 years old (p=0.011) and women 40 to 64 years old (p= 0.021) after adjustment for residence, socioeconomic status, and morbidity. Conclusions: Most of the suicides motivated by physical illnesses contacted medical care during 1 year prior to suicide, but many of them did not undergo psychiatric evaluation. This underscores the need for programs to provide psychosocial support to patients with physical illnesses.

Calf losses have an economic impact on larger Korean native cattle (KNC) breeding farms due to replacement, productivity, and marketing. However, little research on KNC calf mortality or causes of calf death on large-scale breeding farms has been conducted. Based on medical records and autopsy findings from the Hanwoo experimental station of the National Institute of Animal Science, calf death records from 2002 to 2011 were used to identify the causes of mortality. Mortality rate of KNC calves was 5.7%. Large differences (1.8~12.6%) in yearspecific mortalities were observed. Calf deaths were due to digestive diseases (68.7%), respiratory diseases (20.9%), accidents (6.0%), and other known diseases (2.2%). The main cause of calf death was enteritis followed by pneumonia, rumen indigestion, and intestinal obstruction. The greatest number of calf deaths occurred during the fall followed by summer. These results indicated that enteritis and pneumonia were the main reasons for calf death. However, autopsy findings demonstrated that other factors also caused calf death. This study suggested that seasonal breeding and routine vaccinations are the most important factors for preventing calf death, and improving calf health in high land areas with low temperature.

Neonatal mortality rate (NMR) or infant mortality rate (IMR) are the rate of deaths per 1,000 live births at which babies of either less than four weeks or of one year of age die, respectively. The NMR and IMR are commonly accepted as a measure of the general health and well-being of a population. Korea's NMR and IMR fell significantly between 1993 and 2009 from 6.6 and 9.9 to 1.7 and 3.2, respectively. Common causes of infantile death in 2008 had decreased compared with those in 1996 such as other disorders originating in the perinatal period, congenital malformation of the heart, bacterial sepsis of newborns, disorders related to length of gestation and fetal growth, intra-uterine hypoxia, birth asphyxia. However, some other causes are on the increase, such as respiratory distress of newborn, other respiratory conditions originating in the perinatal period, other congenital malformation, diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism. In this study, we provide basic data about changes of NMR and IMR and the causes of neonatal and infantile death from 1983 to 2009 in Korea.

Purpose: To know for what the medical expenditure had been used and to seek the way how it can be efficiently redistributed, I investigated total medical expenditure according to the time period to death in the expired patients for recent 2 years. Methods: 21patients were enrolled in this study. Total medical expenditure including benefit charge and non-benefit charge charged to patients in in-patient department(IPD) and out-patient department(OPD) was counted according to the period for one year by death. Results: 94.7% of the total medical expenditure had been payed for admission-related expenditure and 89% during period 3 and 4 for 6months before death, which may be due to the more days of admission during those periods. 70.1% of the total expenditure had been charged on the admission-fee, room charge, diet, and administration of the fluid, medicines, and blood etc. Conclusion: Majority of medical expenditure has been used in the affairs being unable to improve the survival or quality of life of patients and during the periods closer to death. Here, it would be needed heartily to look for the best ways in detail how the idea of hospice can come true through nation-wide and social consensus.

Life table of Korean population for years 1983 1985 1987 and 1989 were constructed byt the National Bureau of Statics. The ago specific death rates were calculated froom the death registral ion for numerators and the estimated population by age and sex for denominators. In the course of constructing life tables, we have maole some adjustments for deficiencies in regist rat ion olata as follows. First, the non-registered portion oof infant deaths especially for neo-natal deaths was estirnateol and added too the original data. The main reason is that deaths occorring in the neo-natal period and prior to the registrat ion of birth leave little incentive for the registration of either the birth or the death. Second. t he do~hayed p(ortioon of deaths registering after one year of occurrence was estimated and added too the original data. Third t the ptortioon haying in, occuracies in ,~oge reporting was also estimated. Fourth the moving average methood was finally employed in an effort too remove the random error. The major fin(hings are as foolloows. 1. the average life expectancy at birth in 1989 is calculateol as 70.8 years in 1989, 2. a gap netween the male and female life expectancies is widened to more than 8 years toorm 1.8 years in 1906 10. It means that the female life expectancy has increased substantially, 3. the death rates of the middle - aged men starting age 40 are found to he relatively higher than those of females and younger age groups. This peculiar pattern was also found with the comparison of those of other countries.

Objectives: The goal of this study was to identify chronic conditions and multimorbidity patterns in patients with coronavirus disease 2019 (COVID-19) and to examine their associations with pneumonia and death. Methods: This cross-sectional study analyzed the official data of COVID-19 patients in Mexico through May 18, 2020 (released by the Secretaría de Salud de México). Adjusted logistic regression models were applied to assess the associations of comorbidities with pneumonia and death. The marginal effects were estimated, and the probability of pneumonia or death according to the number of comorbidities was graphed for each year of age. Results: Of the 51 053 COVID-19 patients enrolled in the final analysis, 27 667 (54.2%) had no chronic conditions, while 13 652 (26.7%), 6518 (12.8%) and 3216 (6.3%) were reported to have 1, 2, and 3 or more simultaneous conditions, respectively. Overall, a significant incremental gradient was observed for the association between multimorbidity and pneumonia (p<0.001); for 2 chronic conditions, the adjusted odds ratio (aOR) was 2.07 (95% confidence interval [CI], 1.95 to 2.20), and for ≥3 conditions, the aOR was 2.40 (95% CI, 2.22 to 2.60). A significant incremental gradient was also found for the relationship between multimorbidity and death (p<0.001); an aOR of 2.51 (95% CI, 2.30 to 2.73) was found for 2 chronic conditions and an aOR of 3.49 (95% CI, 3.15 to 3.86) for ≥3 conditions. Conclusions: Underlying chronic conditions and multimorbidity are associated with pneumonia and death in Mexican COVID-19 patients. Future investigation is necessary to clarify the pathophysiological processes behind this association, given the high burden of chronic diseases in various countries, including Mexico.
