The clarification of the psycho-social characteristics and causes of suicide attempts would be essential for the establishment of a therapeutic programs as well as preventive measures.
For this purpose, 63 cases of suicide attempts and 68 controls were studied about their demographic characteristics, related life events, depression, locus of control, social support. The study was conducted for 4 months from June 1, 1989, to September 30, 1989. The studied 63 suicide attempts were patients visited emergency rooms of Kangwha Community Hospital, Chunju Jesus Hospital and Suboo Hospital during that period. The controls of 68 patients were selected from psychiatric outpatients of the hospitals at the same period.
The results of the study are summarized as follows:
1. The sex ratio of the subjects was 1:1.5. The mean age was 34.4 years in subjects and 42.5 years in controls. The younger age group (age 15-34) was the most prevalent of the subjects. The middle social class was the most prevalent of the subjects by socio-economic status index.
2. Among the subjects, the proportion of those who had past and family history of suicide attempt was 17.7% and 12.4% respectively. However, they showed no significant difference compared to controls.
The method of suicide attempts showed significant difference according to their localities. The most common method used by the subjects was the ingestion of sedatives in the urban area and the agricultural chemicals in the rural area.
3. In the comparison of mean scores of suicide attempts and controls on th psycho-social scale, the life events scale, Hamilton Depression Rating Scale and the scale of social support showed significant difference. In the scale of locus of control, there was no significant difference.
4. The discriminant analysis was done on age, sex, residences, marital state, socio-economic status index, past and family history of suicide attempt and rated scales. Only by the rated scales, the standardized discriminant function coefficients were calculable on both groups. It follows that an average 83.3% on subjects and an average 57.1% on controls were correctly classified.

This study has been designed to understand the trend of normal delivery pattem based on the data of the annual statistical reports from medical insurance statistical year book of industrial establishment medical insurance and medical insurance for government employees and private school teachers for the period of 8 years from 1980 to 1987.
The results are as follow :
1. Yearly beneficiary rate of health insurance among general population has been markedly increased from 29.8% in 1980 to 60.9% in 1987.
Also it is increased significantly that the enrollment of medical insurance for government employees and private school teachers and Industrial establishment medical insurance from 24% in 1980 to 46.5% in 1987.
2. The number of normal delivery increased proportionately with the increasing number of women in reproductive ages, 15 to 44 years old in the period of 8 years from 1980 to 1987.
However the rate of normal delivery was statistically decreased disproportionately to the increasing rate of fertile women in those years. Also the fertility rate per 1,000 reproductive women decreased.
3. Highest childbirth rate was occured in women of age group between 25-29 yrs with statistical significance.
Childbirth rate was observed predominantly in women age group of 25-29yrs and 30-35yrs, whereas it was decreasing in the rate of childbirth in women under 20yrs of age and 20-24yrs of age.
4. The number of family which has more than 3 children has reduced from 29% in 1980 to 8% in 1987.
It is very significant fact that the most significant reduction of 3 or more children family have occured in the year of 1982 and 1983(from 23% to 17%) when the new insurance policy which rules reject to cover for the delivery of third child or more has applied.
5. In other hand, the rate of cesarean section has increased from 15% of total delivery in 1985 to 17.1% in 1987.

Patients admitted to emergency room of Presbyterian Medical Center for one year were analyzed to evaluate the role of family physicians in emergency room, and the content of primary care.
The results were as follows :
1. The number of patients managed only by family physicians were 1,560 during the study period, and this number constituted 13.5% of 11,568 patients, total patients managed at the emergency room.
2. Among the 1,560 patients the trauma-poison group was 888 cases (56.9%), and nontrauma-poison group was 606 cases(38.8%).
3. In trauma-poison group, predis posing causes were traffic accident(30.9%), C.O. poisoning (10.2%), fall down(9.3%), in order of frequency. The clinical diagnosises were lace ration(35.5%), contusion(20.3%), cerebral concussion(14.3%), in order of frequency.
4. In non-trauma-poison group, health problems were abdominal pain(37.9%), acute urticaria(13.2%), neurotic disorder(12.9%), in order of frequency.
5. The percentage of patients managed within 1 hour was increased from 8.7% to 18.7% after the establishment of department of Emergency Medicine.

To study the various risk factors related with hypertension, 1525 outpatient who visited Soon Shun Hyang Human Dock Center for general check-up for the period from Dec. 1984 to Sep. 1988 were examined by means of questionnaire on living environment and health behavior and laboratory findings.
Hypertension was defined as blood pressure over 160/95mmHg and normotension was difiened as blood pressure less than 140/90mmHg.
Two normotensive people were randomly sampled to one hypertensive person with same age and sex(1:2 matching).
There were 106 for hypertension group and 211 for normotension group. The results are as follows.
1. There was no significant difference between hyertension and normotension group on environmental factors such as housing area, occupation, working hours.
2. In health behavioral factors, obesity with relative body weight more than 20% (P<0.01), weight gain, drinking alcohol (P<0.05) were statistically significant.
3. In laboratory findings, total lipid, triglyceride, prospective atherosclerotic index, EKG findings, chest x-ray findings, urine protein were statistically significant (P<0.01).
