Abstract
To identify the changes in trends of death rates and causes of death for the population of Kangwha County for the past 10 years from 1975 to 1985, the total 652 death occurred during the study period(1981-1985) in three townships(Sunwon, Naegaļ¼Buleon Myuns)were analysed and compared with the previous five-year data(1975-1980).
All death with causes of death were identified and confirmed by health project team consisted of a family health worker, Myun health workers, a public health nurse and field project director.
The major findings of this study were as below:
1. Age adjusted death rate in average for the five-year period(1981-1985) was 5.6 per 1,000 population, 6.9 in male and 4.3 in female respectively which are about 20% reduction in death rate compared with the previous 5 years.
2. In general, age specific death rates revealed an U shaped curve for the past 10 year periods(1975-1985). The age specific death rates particularly for ages under 20 have markedly for both sexes for the study period.
3. Infant and neonatal death rates were markedly decreased from 18.8 and 12.9 per 1,000 live births in the previous period to 8.9 and 4.5 per 1,000 live births in average for the study period. The prematurity was the most common cause of neonatal death both the two study periods one case of neonatal tetanus was found during the 5 year study period.
4. The most common cause of death was cerebrovascular diseases with the magnitude of 139.1 per 100,000 population, in 5 year average, 148.9 in male and 122.5 in female. However, it showed a decreasing trend in comparing with the previous period(180.8 per 100,000:1975-1980)
5. The next leading cause of death was malignant neoplasms with magnitude of 120.7 per 100,000 population, 143.9 in male and 87.5 in female. However, an increasing trend in comparing with the previous period(94.5 per 100,000:1975-1980). All types of accidents rose to the 3rd from the 4th leading causes of death.
6. 84.4% of all deaths were due to any type of disease entities and suicide and poisoning/accidents comprised 5.7% and 5.4% respectively.
7. The proportion of treatment received from health care facilities(including drug stores, herb clinics, hospitals) prior to death increased, from 57.0% in 1975 to 68.1% in 1985. The most common place of death occurred was residence of their own(with 86.7%) and only 5.0% of deaths were occurred in hospital. This pattern persisted without changes for the past 10 years.

Abstract
Arterial blood pressures, height, weight, skinfold thickness, blood pressure, 2 lead ECG, serum cholesterol of 1169 voluntary participants whose age were between 40-64 were examined in a rural community Korea in order to identify risk factors in developing CVD.
The influences of 19 enables on the blood pressure were examined and their independent association with blood pressure was analyzed by means of multiple regression analysis. The most important factors influencing both systolic and diastolic blood pressure were: age, weight, height and cholesterol. The following factors were identified significantly correlated with blood pressureļ¼ pulse rate, hemoglobin and triglyceride.
All 19 variables including modified variable from weight, height and age (Ponderal index, Quetelet index, age2, age3, weight2, weight3) could explain 14.4% of total variation of systolic blood pressure and 20.5% of total variation of diastolic blood pressure. Among 25 variables the most important factors influencing systolic blood pressure were: Ponderai index, age, Quetelet index, cholesterol and pulse rate.
With these 5 variables 13% of total variation of systolic blood pressure could be explained. The most important factors influencing diastolic blood pressure were: weight, cholesterol, ponderal index, hemoglobin and triglyceride. With these 5 variables 16% of total variation of diastolic blood pressure could be explained.

Abstract
To identify mortality pattern of a rural community, the total death, 711 occurred in three townships (Sunwon, Naega, Buleon Myuns) in Kang Wha County during 1975-1980 were studied.
All death was reported weekly to health workers by 37 family health workers of villages. Causes of death was identified by one public health nurse & three public physicians using questionnaries.
This study focuses on death rates & causes of death.
The following is brief summary of results of the study.
1) Crude death rates
The trend in the crude death rates showed slowly downward tendency & especially male. 5-year (1976-1980) average crude death rates was 7.9 per 1,000 and 8.6 in male & 7.2 in female.
2) Age-specific death rates revealed a U-shape & similiar patterns were shown during the study period.
3) The trend in the infant death rates showed also downward tendency. 5-year average infant death rate was 12.9 per 1,000 live births and the neonatal death rate 18.8. The most common cause of neonatal deaths was prematurity.
4) Proportional Mortality Indicators ranged between 71%-83%.
5) The most common cause of deaths was cerebrovascular diseases (180.8 per 100,000) and was followed by malignant neoplasms (94.5 per 100,000).
The death due to pulmonay tuberculosis ranked 5 with a death rate of 47.2 per 100,000 and the death due to pneumonia & respiratory diseases ranked 10 with a death rates of 11.5 per 100,000.
