Background
: It is expected that Korea Medical Insurance and Health Care Delivery System made change the contents of inpatients in Family Medicine and increased the role of Family Mediine in primary care. We have tried to prove the above hypothesis by comparative study on the inpatient related seeral factors in the year of 1998 and 1991.

Methods : We examined the medical records of the patients who were hospitalized to the department of Family Medicine, Korea University Kuro Hospital from January 1. 1998 through December 31, 1988 and January 1, 1991 through December 31, 1991. We analyzed the number of patients, age, sex, living district, the length of stay, the route of admission, condition at the time of discharge, and diagnosis.

Results : A total of 95 patients were hospitalized in 1988 and those of 183 patients in 1991. The increased rate of total numbers of hospitalized patients was 92.6%. There were no significant difference in age, sex, living district distribution in between those study groups. The length of stay was increased from 5.8±3.8 days to 13.3±8.2 days. In the route of admission, the patients via out patient department was decreased from 97.8% to 91.8% and those via emergency room was increased from 2.2% to 8.2%. In patient's condition at the time of discharge, improved state was increased from 38.9% to 66.7% and unimproved state was decreased from 49.5% to 16.9%. In 1988, the most common diagnosis was chronic hepatitis of 14 cases(14.7%) and the next was neurotic disorder of 8 cases (8.4%). In 1991, the most common diagnosis was diabetes mellitus of 20 cases(11.0%) and the next was acute and subacute necrosis of liver of 12 case(6.6%).

Conclusion : It is concluded that these changes were induced by increased hospitalization for treatment compared to decreased hospitalization for diagnosis due to decreased the amount of money that patient has to pay from their own pocket besides medical insurance coverage. Also, it is believed that the increased role of family medical insurance coverage. Also, it is believed that the increased role of family medicine in primary care affected these changes.

Background
: In recent years, the incidences of atherosclerosis is increased among Korean because of socioeconomic and diet change. And it is known that many biochemical markers for atherosclerosis including serum total cholesterol, triglyceride, LDL-cholesterol and HDL-cholesterol are exist. Among these markers, serum total cholesterol is most basal parameter for screening the risk of atherosclerotic coronary heart disease. In order to determine the cut off value of serum total cholesterol for risk of atherosclerosis in Korean people, we carried out this study.

Methods : Data were gathered from 679 adults over 20yrs-old who were evaluated for general check-up during period from June 1990 to May 1991. Except 383 abnormal groups on physical examination and laboratory study, 296 healthy groups was analyzed and evaluated. Serum total cholesterol, LDL-cholesterol, triglyceride level was distributed with age, and serum total cholesterol was utilized for cut-off point.

Results : The serum total cholesterol and LDL-cholesterol were increased with age in both sex, and triglyceride was increased with age in woman but in men. There were no relation-ship between HDL-cholesterol and age. There was no significant difference of serum total cholesterol by sex. The cut-off point of total cholesterol for moderate risk was 186mg/dl at 3rd decade, 202mg/dl at 4th decade, and 205mg/dl at 5th decade, and 223mg/dl at 6th decade, and 249mg/dl at 7th decade. Also the cut-off points of total cholesterol for high risk were 202mg/dl at 3rd decade, 223mg/dl at 4th decade, 229mg/dl at 5th decade, 236mg/dl at 6th decade and 260mg/dl at 7th decade.

Conclusion : Results of this study may be not sufficient to apply on all Korean adults because this study group was limited and small. But we tried for cut-off value of serum total cholesterol for risk group of atherosclerosis. And, further study and effort for reducing the risk of atherosclerosis should be evaluated.
