This study was performed in order to assess the factors influencing pregnant women's behavior in oral iron supplement and to document the reasons to stop oral iron supplement.
The 260 women's data which were collected by chart review and the responses to the prepared questionnaire in Bucheon Se Jong Hospital during 4 months(May, June, July, August) in 1990, were as analyzed.
The results were as follows :
1. The percentage of the women who took oral iron pill was 56.2%.
2. There was significant increase in the oral iron supplement if the pregnant women had higher education or the more income or antenatal care or the knowledge for iron supplement during pregnancy.
3. The most common reason for iron supplement during pregnancy was the knowledge for iron supplement. Then the doctor's advice was the second and the husband's advice was the third.
4. They discontinued iron supplement during pregnancy due to the side effects(32.9%), annoying continuous use(25.7%), forgetting the use(18.6%) and satisfying to herself(5.7%).
5. The mean values of hemoglobin and hematocrit were 11.8gm/dl and 35.3% in adequate supplement group, 11.0gm/dl and 33.3% in inadequate supplement group, and 10.0gm/dl and 30.9% in non-supplement group.

A clinical observation was made on 102 cases of drug intoxication admitted to the Seoul Christian Hospital via emergency room during one year from March 1989 to February 1990.
The observed results were as follows;
1. The ratio of drug intoxicated patients to total patients of emergency room was 1.6%.
2. Female was slightly more than male(1.2:1) and the age group of the third decade was of the largest proportion.
3. The motives of most intoxication(97.0%) were suicidal attempts.
4. In monthly distribution, July had the largest proportion(14.7%). The largest proportion of the time interval on arrival at emergeney room and of presumed time of poisoning was night(8 pm-12 pm).
5. The most common drug of intoxication was rodenticides(28.4%), the remainders were insecticides(21.6%) and sedatives(19.6%).
6. The chief complaints of the patients on admission were mental change(40.5%), nausea and vomiting(19.1%), abdominal pain(10.0%), but asymptomatic cases were as 18.1%.
The observed abnormal vital signs were tachypnea, hypertension, tachycardia and elevated body temperature in order of frequency.
7. The observed abnormal laboratory findings on admission were leukocytosis(57.4%), elevated transaminase(20.0%), elevated blood sugar(16.0%), anemia(13.8%) and elevated serum creatinine(5.3%).
8. The outcomes of the patients were recovery(64.7%), discharge against medical advice and transfer to other hospital(26.5%) and death(8.8%).

To test the hypothesis that family function differs in diabetic patients according to their level of glycemic control, family function was assessed using the Family Adaptability & Cohesion Evaluation Scales Ⅲ(FACESⅢ) questionnaire.
From June to August, 1990, 57 patients with adult-onset diabetes mellitus(Type Ⅱ NIDDM) to be diagnosed and managed for more than 6 months in the Youngdong Severance Hospital were randomly selected. The patients were divided into three groups(good, fair, poor) according to the level of their glycemic control which was obtained in the clinic visits during the 6 months before the date of the assessment of family function.
The results were as follows:
1. There was no statistically significant difference in the state of glycemic control when related to age, duration of diabetes, income, and marital status ; however, there was a statistically significant difference in the state of glycemic control when related to enforcement through diet therapy.
2. In the cohesion according to the level of glycemic control, separated and connected types were more common in the good and fair control groups than in the poor control group, and disengaged type was more common in the poor control group than in the good and fair control groups. This result was statistically significant.
3. In the adaptability according to the level of glycemic control, structured and flexible types were more common in the good and fair control groups than in the poor control group and chaotic type was more in the poor control group than the good and fair control groups.
This was not statistically significant.
4. In the family types according to the level of glycemic control, the relatively more extreme family type was effected more significantly in the poor control group than in the good and fair control groups.

Serum cholesterol, one of the major risk factors of cardiovascular diseases including coronary heart diseases, increases with age and is related to sex, height, obesity, smoking, blood pressure, exercise and stress. To explore the relationship between age or relative body weight and serum cholesterol, we examined serum cholesterol in 673 healthy persons aged more than 20.
The results obtained were as follows :
1. The relationship bewtween age and serum cholesterol was positively associated showing simple linear increase in women.
2. In men, the higher the relative body weihgh, the higher the serum cholesterol. In women, the effect in relative body weight-serum cholesterol relationship was less than in men, while serum cholesterol increased with age independently with relative body weight.
3. In multiple regression analysis associated with age and relative body weight in explaining the variations of serum cholesterol, the association between serum cholesterol and relative body weight was statistically significant in men, but in women the association with age was statistically significant.
Our results suggest that family physicians had to recommend and educate the necessity to reduce body weight, especially in obese men.

82,104 cases of general health people were obtained from Jan. 1986 to Dec. 1989 at Korea Medical Insitiute(KMI) and an immunological studies for rheumatoid arthritis have been performed by using Latex agglutination method(RA 80 'Eiken, Eiken Chemical Co., Ltd.)
The results were as follows:
1.The sera of positive rate of qualitative test were 4,921 cases(8.2%) in male (60,204), 1,569 cases(7.2%) in female (21,900)(average 7.9%)
2. Age distribution of positive rheumatoid factor showed 119 cases(5.1%) in 10~19 year old group, 1,192 cases(5.5%) in 20~29 year old group, 2,230(7.5%) in 30~39 year old group, 1,780(9.5%) in 40~49 year old group, 906(11.5%) in 50~59 year olf group, 224(14.1%) in 60~69 year old group, 39(17.5%) in over 70 year old group. The positive rate of qualitative RF test increased with age.
3. The sera of significant titer(1 : 80 or higher) by quantitative RF test were revealed only in 1.2% among the positive sera of qualitative RF test.
From the above results, we concluded that rheumatoid factor seems to be not a good index for screening test of rheumatoid arthritis.

A clinical study has been made on 76 cases of acute pyelonephritis out of 28,104 patients who were delivered at Ilsin Christian Hospital from January 1986 to December 1989. And 87 normal cases during the same period were selected as a control group.
The incidence of with acute pyelonephritis during pregnancy was 107 cases (0.3%). The acute pyelonephritis developed in 47.7% in second trimester and in 42.1% in third trimester.
Common symptoms and physical findings were flank pain(71.1%), fever(75.1%) and tenderness on costovertebral angle(87.8%).
Urine cultures were positive in 81.4% of cases, the most frequent organism was Esherichia coli (67.1%) which was sensitive to the cefoperazone. The next frequent organism was coagulase negative staphyloccocci.
Average gestational age was 39.3 weeks and average birth weight was 3.20kg.
Intrapartum and postpartum maternal morbidity was significantly higher in the study group than in the control group (P<0.01).
Fetal morbidity was 63.1% in the study group and 32.2% in the control group, which was statistically significant (P<0.01).
As far as fetal morbidity was concerned, only fetal distress showed significant (P<0.05).
Patients who had fever for more than 3 days showed higher incidence of fetal and/or maternal morbidity (P<0.01).
There were five cases (6.6%) of recurrence and readmission.
In conclusion it would seem that acute pyelonephritis during pregnancy is not a causative facter in prematurity or low birth weight but it is important that it be treated quickly during pregnancy because of the higher incidence of fetal and/or maternal morbidity.

A retrospective study has been made of 1,253 cases of traffic accidents which had been treated at the H hospital in Seoul from May 1989 to April 1990.
This study was conducted to find out the nature and pattern of the traffic accident from the clinical and epidemiologic standpoint. The aims of this study were not to indicate direct preventive measures but focus attention on fields in which best results should be given by the preventive measures.

The following results were obtained;
1. Accidents occurred most frequently from 6 p.m. to midnight, 54.2%.
Although there was no significant difference, the descending order of monthly incidence was January(12.3%), March(9.6%), and August(9.6%).
2. Male to female ratio was 2.63:1.
The highest incidence was in age group between 20-29 year(34.7%).
3. The majority of trauma was from taxi and passengers' car (64.1%).
Pedestrians were most commonly injured(43.4%).
4. The types of injury were almost neurosurgical and orthopedic injury(88.1%).
5. Abrasion and contusion were most frequent(25.0%) and cerebral concussion was 21.7%.
6. In abdominal trauma, small bowel (33.3%), spleen(25.0%), liver(12.5%), kidney(8.3%) was the descending order of frequency.
7. Brain damages were responsible for the majority of cause of death (53.6%) and mortality rate was 4.1% in the admitted patients.
