PURPOSE
This study was conducted to analysis the trends and states of external auses of mortality in Korea from 1985 to 1998.
METHODS
This study was based on data published in 1985-1998 from the annual report of cause of death statistics of National Statistical Office.
RESULTS
In the proportion of total death cases during 1985-1998, External causes of mortality was ranged from 11 percent to 15 percent. Death rate(per 100,000) of external causes of mortality(ECM) decreased recently from 85.7 in 1991 to 68.9 in 1998. Death rate of ECM in male was 2.6 times higher than that of female. Among total cases of ECM, the first leading cause of death was transport accidents. intentional self-harm was the second leading cause of death(26.8 percent in 1998). In trends of death rate(per 100,000) for ECM during 1885-1998, there were decreased for following causes of death; transport accidents, falls, accidental drowning and submersion, exposure to smoke, fire and flames, accidential poisoning by and exposure to noxious substances, Death rates of ententional self-harm and assault were increased during the periods. The age specific death rate increased with age for all ECM except for assault. The risk of death caused by ECM was higher in aged 65 and over than in ages 0-19 years among all ECM. The risk of death for male aged 65 and over were 6.9 times in transport accidents, 26 times in fall, 37 times in accidential poisoning by and exposure to noxious substances, and 18 times in intentional self-harm compared with 0-19 years. The risk of death for female aged 65 and over were 27 times in fall, 22 times in accidential poisoning by and exposure to noxious substances compared with 0-19 years. In seasonal variation of ECM cases for 1998. There was highest proportion in August(10.4 percent). The highest proportion by death seasion were winter(32.7 percent) in exposure to smoke, fire and flames, summer(27,7 percent) in fall, summer(52.4 percent) in accidental drowning and submersion, summer in 32.0 percent) in accidential poisoning by and exposure to noxious substances, spring(28.2 percent) in intentional self-harm, assault. and autumn(28.2 percent) in transport accidents.
CONCLUSION
Above results suggest that a preventive education program for safety accidents should be developed by considering gender and age of the objecties and seasons of the year.

Among 950 subjects, the prevalence rate of low back pain showed 46.5%, premarital low back pain experience consist of 15.6%, postmarital low back pain was 70.6%. 3. In relation of general characteristics and low back pain prevalence, the age, age of marriage and number of family showed no significance but education, economics and lenght of marriage were highly significant (p<0.01). 5.

In relation of obstetric and gynecology factors and low back pain prevalence, number of child birth and method of child birth were not significant but statistically significant to amount of house work during pregnancy and highly significant The cause of low back pain consist of 28.0% unknown, 18.1% claim of long period of working with squatting position, 15.6% claim long period of work with stoop position. The type of low back pain symptom among present low back pain group consistent of 83.7% are low back pain only, 44.3% and 38.5% have distal and proximal radiating pain respectively and 21.0% felt weakness to lower extremities. Among the present low back pain group, 76.9% have experience of treatment, in that 47.5% low back pain medical information gained through friends high risk factors by biological, house and house-work environment.
