Present study was undertaken to establish the modified Broca's indices to estimate standard body weight by using a total of 5,496 insured persons who were medically examined at the Honam Medical Room of Dong Bang Life Insurance Company Ltd. from January, 1983 to January, 1986. The results were as follows: 1. The linear regression equations of body weight to $height^3$ to estimate standard body weight were as follows: In male, for $18{\sim}19$ age group $y=7.272{\times}10^{-6}{\times}x^3+23.560$ for $20{\sim}29$ age group $y=8.187{\times}10^{-6}{\times}x^3+22.031$ for $30{\sim}39$ age group $y=8.627{\times}10^{-6}{\times}x^3+23.169$ for $40{\sim}49$ age group $y=9.561{\times}10^{-6}{\times}x^3+20.994$ for $50{\sim}59$ age group $y=8.604{\times}10^{-6}{\times}x^3+23.081$ and for all ages group $y=7.778{\times}10^{-6}{\times}x^3+25.929$ In female, for $18{\sim}19$ age group $y=8.252{\times}10^{-6}{\times}x^3+18.920$ for $20{\sim}29$ age group $y=7.715{\times}10^{-6}{\times}x^3+22.409$ for $30{\sim}39$ age group $y=8.808{\times}10^{-6}{\times}x^3+21.440$ for $40{\sim}49$ age group $y=9.691{\times}10^{-6}{\times}x^3+21.940$ for $50{\sim}59$ age group $y=12.550{\times}10^{-6}{\times}x^3+11.031$ and for all ages group $y=7.300{\times}10^{-6}{\times}x^3+26.601$ In both sexes, for all ages group $y=8.342{\times}10^{-6}{\times}x^3+22.998$ 2. The modified Broca's index is expressed by formula $\{height(cm)-100\}{\times}K(kg)$. K is obtained from the following formula standard weight to average height estimated $\frac{by\;means\;of\;linear\;regression\;equation(kg)}{\{Average\;height(cm)-100\}{\times}K(kg)}$=1 Author's modified Broca's indices are as follows: In male, for $18{\sim}19$ age group $\{height(cm)-100\}{\times}0.85(kg)$ for $20{\sim}29$ age group $\{height(cm)-100\}{\times}0.90(kg)$ for $30{\sim}39$ age group $\{height(cm)-100\}{\times}0.95(kg)$ for $40{\sim}49$ age group $\{height(cm)-100\}{\times}1.00(kg)$ for $50{\sim}59$ age group $\{height(cm)-100\}{\times}0.95(kg)$ and for all ages group $\{height(cm)-100\}{\times}0.95(kg)$ In female, for $18{\sim}19$ age group $\{height(cm)-100\}{\times}0.90(kg)$ for $20{\sim}29$ age group $\{height(cm)-100\}{\times}0.90(kg)$ for $30{\sim}39$ age group $\{height(cm)-100\}{\times}1.00(kg)$ for $40{\sim}49$ age group $\{height(cm)-100\}{\times}1.05(kg)$ for $50{\sim}59$ age group $\{height(cm)-100\}{\times}1.05(kg)$ and for all ages group $\{height(cm)-100\}{\times}1.00(kg)$ In both sexes, for all age group $\{height(cm)-100\}{\times}0.95(kg)$ 3. Several types of modified Broca's index recommended by author are as follows: I. In male, for $18{\sim}29$ age group $\{height(cm)-100\}{\times}0.90(kg)$ and for $30{\sim}59$ age group $\{height(cm)-100\}{\times}0.95(kg)$ In female, for $18{\sim}29$ age group $\{height(cm)-100\}{\times}0.90(kg)$ and for $30{\sim}39$ age group $\{height(cm)-100\}{\times}1.00(kg)$ II. In male, for all ages group $\{height(cm)-100\}{\times}0.95(kg)$ In female, for all ages group $\{height(cm)-100\}{\times}1.00(kg)$ III. In both sexes, for all ages group $\{height(cm)-100\}{\times}0.95(kg)$ Note: The first type of modified Broca's index is the most precise one in estimating standard body weight among several types established by author. 4. Error of estimated standard body weight appearing by applying modified Broca's indices is generally greater in short build persons than in tall build persons and is more dominant especially in female group.

We'd performed the upper gastrointestinal study for a total of 1,033 insureds-male 630, female 403 persons-who were examined at medical dept. of Dae Han Kyoyuk Insurance Co., Ltd., from August, 1986 to January, 1987. The results on diverticulum were as follows; 1. The incidence rate of duodenal diverticulum is exceptionally higher than esophageal diverticulum. 2. In all of 53 insured who have duodenal diverticulum and esophageal diverticulum, there was little difference between male and female in the incidence rate of diverticulum; 5.08% in male, 5.21% in female. 3. The possessing rate of both diverticulums increased by age regardless of sex. ; 0.71% in 20yrs, 2.12% in 30yrs, 11.11% in 40yrs, 12.75% in 50yrs, 30.43% in 60yrs more. 4. The possessing rate of both diverticulums in male is 0% in 20yrs, 1.97% in 30yrs, 7.21% in 40yrs, 15.09% in 50yrs, 27.27% in 60yrs more and in female, 1.16% in 20yrs, 2.40% in 30yrs, 7.87% in 40yrs, 10.20% in 50yrs, 33.33% in 60yrs more. 5. Those who have duodenal diverticulum 47 insureds felt the following subjective symptoms; uncomfortable 8.51%, heartburn and tingling each 4.26%, sore throat 2.13%and esophageal diverticulum's heartburn 16.67%. 6. There occurred the following complications in 47 insureds with duodenal diverticulum-gastric polyp, erosive gastritis, antral gastritis, cascade stomach, fatty liver, polyp in GB and choledocholithiasis; each 2.13% and cholelithiasis 6.38% and cascade stomach. 7. All duodenal diverticulum occurred in duodenal inlet. 8. The number of lesion was single in all esophageal diverticulum, but there was each one case with 2 lesions and 3 lesions in duodenal diverticulum.

We've reviewed 704 cases of claims by death that had occured for one year from April, 1985 to March, 1986. As a result, we came to following conclusions; First, the greater part of the death were due to Accidental death(25.0%), Malignant neoplasm(21.2%), Heart disease(12.9%), Liver cirrhosis(9.1%), and the cerebrovascular disease(5.5%), which were occupied by 73.7% of the whole. Second, classifying them by medical examinations or non medical, death in case of non medical examinations showed 94.3% of whole. And for age, section ranging from 40 to 49, from 50 to 59, and from 60 to 69 took the overwhelming portion by 28.6%, 24.2%, and 16.6% respectively, those of wich showed 69.4% of the whole. Third, for the period elapsed, death within 1 year from the entrance showed 16.9% and that from 1 year to under 2 years 18.8%, Thus the rate of early death under 2 years stood for 35.7% of the whole.

The present study was undertaken to establish the standard body weight by height in Korean adults by using the actually measured heights and weights of a total of 5,496 insured persons who were examined medically at the Honam Medical Room of Dong Bang Life Insurance Company, Ltd. from January, 1983 to January, 1986. The results were as follows: 1. The linear regression equations to establish the standard body weight of Korean adults were as follows: In male, for $18{\sim}19$ age group, $y=7.272{\times}10^{-6}{\times}x^3+23.560$ for $20{\sim}29$ age group, $y=8.187{\times}10^{-6}{\times}x^3+22.031$ for $30{\sim}39$ age group, $y=8.627{\times}10^{-6}{\times}x^3+23.169$ for $40{\sim}49$ age group, $y=9.561{\times}10^{-6}{\times}x^3+20.994$ and for $50{\sim}59$ age group, $y=8.604{\times}10^{-6}{\times}x^3+23.801$ In female, for $18{\sim}19$ age group, $y=8.252{\times}10^{-6}{\times}x^3+18.920$ for $20{\sim}29$ age group, $y=7.715{\times}10^{-6}{\times}x^3+22.409$ for $30{\sim}39$ age group, $y=8.808{\times}10^{-6}{\times}x^3+21.439$ for $40{\sim}49$ age group, $y=9.691{\times}10^{-6}{\times}x^3+21.940$ and for $50{\sim}59$ age group, $y=12.500{\times}10^{-6}{\times}x^3+11.031$ 2. The standard age, height, and weight tables by author were presented with the aid of linear regression equations. 3. The values of standard body weight by height established by author reveal to be a little higher than those of other Korean reports through all age groups of both sexes, and reveal to be considerably similar, compared with those of the reports in Japan for fourth and sixth decade of female group.

A study on hepatomegaly detected by abdominal palpation, and facial telangiectasia in a total of 3,418 insured persons medically examined at the Honam Medical Room of Dong Bang Life Insurance Company Ltd. from February, 1984 to August, 1985 was undertaken. The results were as follows: 1) Hepatomegaly was found in 383 cases(27.5%) among the 1,395 insureds of male and in 163 cases(8.1%) among the 2,023 insureds of female. The difference of incidence of hepatomegaly between all males and females showed statistical significance(p<0.001). In each age group, the incidence of hepatomegaly in :nale was higher than that in female. The incidence of hepatomegaly in each age group in male increased cnosiderably with age; it showed 11.6%,16.2%, 42.6% and 52.9% from second to sixth decade in order, thereafter in seventh decade it decreased to 26.7%, While the incidence of hepatomegaly in female increased slightly in each age group. 2) Facial telangiectasia was found in 318 cases(22.8%) among all males and in 157 cases(7.8%) among all females. The difference of incidence of telangiectasia between all males and females showed statistical significance(p<0.001). In each age group, the incidence of telangiectasia in male was higher than that in female, except of second decade. The incidence of facial telangiectasia in each age group in male increased considerably with age; while it increased slightly in female. 3) Facial telangiectasia accompanied by hepatomegaly was found in 235 cases(61.4%) among 383 cases of hepatomegaly in male and in 69 cases(42.3%) among 163 cases of hepatomegaly in female. The difference of incidence of telangiectasia between males and females show ed statistical significance(p<0.001). 4) Facial telangiectasia without spider angiomata accompanied by hepatomegaly was found in 201 cases(52.5%) among 383 cases of hepatomegaly in all males and in 67 casgs(41.4%) among 163 cases of hepatomegaly in all females; facial spider angiomata accompanied by hepatomegaly was found in 34 cases(8.9%) among 383 cases of hepatomegaly in all males and in 2 cases(1.2%) among 163 cases of hepatomegaly in all females. 5) Abnormal SGOT activity was found in 19 cases(7.9%) among 242 cases of hepatomegaly in all males and in one case(1.5%) among 67 cases of hepatomegaly in all females. The difference of incidence of abnormal SGOT activity showed statistical significance(p<0.001). The incidence of abnormal SGOT activity by the size of hepatomegaly, that is, palpated <1 finger's breadth, <2 fingers' breadth and ${\geqq}2$ fingers' breadth, revealed 2.2%, 6.0% and 60.0% respectively in all males, while abnormal SGOT activity was found only one case in fifth decade among 67 cases of hepatomegaly in all females. 6) In ordinary medical examination(the insured amount is low) abnormal SGOT activity was found in 7 cases(4.8%) among 146 cases of hepatomegaly palpated $1\frac{1}{2}$ fingers' breadth and under, while it was not found in 37 cases of the same sized hepatomegaly in all females. Above mentioned 7 cases are thought to be very significant because 7 cases occupy 35% in 20 cases of abnormal SGOT activity with hepatomegaly. 7) Abnormal SGOT activity was found in 12 cases(4.4%) among 273 cases of hepatomegaly of "not firm" consistency, while it was found in 8 cases(22.2%) among 36 cases of hepatomegaly of "firm" consistency. The difference of incidence of abnormal SGOT activity showed statistical significance(p<0.05). 8) Abnormal SGOT activity was found in 5 cases(17.9%) among 28 cases of spider angiomata with hepatomegaly, while it was found in 10 cases(7.3%) among 166 cases of telangiectasia without spider angiomata with hepatomegaly. Owing to a small number of cases, statistical significance was not recognized, but the incidence of abnormal SGOT activity in spider angiomata cases with hepatomegaly is apt to be higher than that in telangiectasia cases without spider angiomata with hepatomegaly. 9) The incidence of abnormal SGOT activity is apt to be higher with age in male group; abnormal SGOT activity was not found among 4 cases of hepatomegaly in second decade and it was 3.8% in third decade, 4.5% in fourth decade, 9.3% in fifth decade, 17.5% in sixth decade and 33.3% in seventh decade, while the incidence of it was only one case among 67 cases in all females. 10) It is believed that the performance of liver function test to the subjects with hepatomegaly even in ordinary medical examination(the insured amount is low) will give considerable contribution for medical selection of hepatomegaly risk. 11) Age of the insured(young or old), presence of facial telangiectasia or spider angiomata especially and their severity, and consistency of enlarged liver(firm or not) should be considered to increase accuracy in evaluating hepatomegaly risk.
