1.Methodological Aspects of a Telephone Survey on the Behavioral Risk Factors in Korea.
Journal of the Korean Academy of Family Medicine 1997;18(10):1054-1068
BACKGROUND: A survey is the only direct way of determining the distribution of behavioral risk factors among a population. The department of Family Medicine in Seoul national university hospital adopted telephone interviewing for collecting information about behavioral risk factors of Koreans. Because methodological aspect of telephone survey is different according to the telephone and communication environment of the area in which the survey would be held, we tried to figure out adequate methodological aspects of a telephone survey on the behavioral r isk factor in Korea. METHODS: We sampled telephone numbers from the telephone number database which is supported by Infornet Ltd. with stratified cluster random sampling method and selected respondent by using algorithm of Kish. 13 part-time job interviewers were trained for 6 hours and then interviews were made in a fixed area for the time assigned. RESULTS: 13 interviewers tried to do 1,826 interviews for 4 weeks. Sociodemographic characteristics of respondents were compared with the census estimates and another face to face interview and there were no significant differences. A response rate of 79.8%, refusal rate of 12.9% and interview efficiency of 58.1% were obtained, yielding 1060 completed interview. A total of 28,830 person minutes of interview time were spent on the survey with an average of 27.2 minutes per completed interview. CONCLUSIONS: Sampling method using the telephone number database could be used keeping the representativeness of the samples and telephone survey was considered to be reliable and affordable method for determining the prevalence of behavioral risk factors in Korea.

2.The Effects of Long-Term Training of Aerobic Exercise on Some Risk Factors of Cardiovascular Disease.
Korean Circulation Journal 1990;20(2):226-231
25 males, aged 40-60 years, who participated in aerobic-type exercise on moderate intensity(60~85% of MHR), 3~5 days a week for 6~12 months were selected. Data were obtained at pre- and post-participation of tranining period for height, weight, girths of chest and abdomen, body fat, BP, HR, serum cholesterol, triglyceride, HDL-cholesterol, glucose, uric acid, BP and HR during graded treadmil exercise, and VO2max. After training for average 38.4 weeks, significant reductions occured in percent of body fat, HR and SBP both at rest and exercise, triglyceride, but not in cholesterol, LDL-cholesterol. And DBP, HDL-cholesterol were elevated. VO2max was increased apparantly by 16.4%. From the results was concluded that training of aerobic exercise could reduce the risk of coronary heart disease by 1) decreasing myocaridal oxygen demand, 2) improving on lipid profile, 3) increasing cardiac work capacity.

Korean Ginseng (Panax C.A. Meyer) has survived empirical efficacy as tonic and geriatric agents for several thousands of years in oriental herbal medicine. But there has been numerous controversial reports about its use in aged hypertensive men due to its allegedly hypertensive effects. Therefore, the author conducted the pharmacological studies of Korean Ginseng extracts on the blood pressure and blood lipid metabolism, during development of hypertension, using SHR(Spontaneously Hypertensive Rat), counterpart model of human essential hypertension. The results obtained were as follows: 1. SHR could be grouped, according to their age, as prehypertensive stage(<6th week after birth), labile hypertensive stage(6th 14th week), early established hypertensive stage(14th-20th week), and late established hypertensive stage(>20th week). 2. Plasma renin activity tended to rise steadily, until established hypertensive stage was reached. Thereafter, plasma renin activity tended to decline. 3. The changes of blood pressure due to Ginseng extract, depended on the amount, route and duration of its administration. Low dose of Ginseng tended to increase blood pressure but high dose of Ginseng tended to decrease blood pressure, until 1 week of intraperitonal administration. But prolonged administration of Ginseng extract beyond 1 week, showed delayed hypertensive effect in the intraperitoneal administration but not in oral administration. 4. SHR seemed to have abnormalities in the lipid metabolism. SHR showed lowered level of serum cholesterol and phospholipid, whereas slightly higher level of triglyceride, and showed lower alpha-lipoprotin fraction but higher pre beta-lipoprotein fraction, as compared with NCR.(=Normal Control Rat). 5. When high fat cholesterol salt diet was fed on, it was possible to indece hyperlidemia and increment of hypertension in SHR. but when high fat cholesterol salt diet and Ginseng extract were fed on concomitantly, Ginseng showed significant inhibiting effect on the development of hyperlidemia and hypertension.
