This report is a part of the health survey, which was carried out in the summer of 1973 on all adults older than 15 years of age, inhabiting in the sampled area. Thirteen villages out of 31 natural villages in Shindong Myon, Chunseong Gun, Kangwon Province, a typical rural area of Korea were randomly sampled. A little over 70 percent of the population sampled, or 1198 persons were examined. The health survey included laboratory screening tests, history taking, physical examination and consultation to specialists for selected cases. Diseases of circulatory system were classified by WHO ICD A-List (150). Hypertensive heart disease was defined by the criteria that was used in U.S. Health Survey, and hypertension by WHO criteria for the purpose of comparison. Results obtained were as followings: 1. The overall prevalence of the diseases of circulatory system per 100 adults examined was 8.6 for male and 9.9 for female. 2. Age specific prevalence of the diseases showed gradually increasing pattern as age advanced for both sexes. For example, the prevalence for 15~19 years old age group was 2.4/100 adults which increased to 24.8 when age reached over 60 years. 3. The most prevalent disease category, 3.6/100 adults, was A-88: other diseases of circulatory system that was consisted mainly of varicose vein and hemorrhoids; the second one was hypetensive heart disease, 2.4. 4. Female had higher prevalence than male in A-84: other form of heart diseases (4 times, arrhythmia, beriberi heart disease, and heart disease secondary to anemia), in chronic rheumatic heart disease (4.5 times), and in hypertensive heart disease (1.4 times); in other hand, cerebrovascular diseases (4.5 times) and diseases of arterioles and capillaries (1.5 times) occurred more frequently among males than females. 5. The proportion of hypertensive heart disease among persons with definite hypertension was 22.0% for male, 25.8% for female, and it increased gradually as age increased. Hypertensive heart disease among persons with borderline hypertension was 2.2%. Only 27% of hypertensive heart disease patients had previous treatment for hypertension. 6. The prevalence of definite hypertension per 100 adults examined (double blood pressure check with interval of 30~40 minutes) was 9.5 for male, 9.4 for female, with increasing pattern by advancing ages; marked increase occurred after age of 45 years for male and 35 years for female. The prevalence of hypertension in this study was much lower than that of the study on employees of Korea Electricity Comparny when compared with the same age groups. 7. Electrocardiographic findings on 105 heart disease suspects revealed left ventricular hyperspecific change in 4 persons. This study was supported by China Medical Board of New York Inc.

In Korea, the nosocomial infection control program is not well estabilished. This study was carried out to investigate the incidence rate of nosocomial infection occurred among patients of 18 hospitals for 7 days ; cases of hospital infection per 10,000 patients discharged during the same period in Korea. The study was done in 18 volunteer hospitals and nosocomial infection cases for 7 days were collected retrospectively. The result was as follows; 1. The incidence rate of nosocomial infection for 7 days was 578 cases per 10, 000 patients discharged. 2. Pneumonia was the most prevalent nosocomial infection ; the incidence rate 112.7 cases per 10,000 discharges. The incidence rate of urinary tract infection was 85. 7 cases and that of septicemia was 36. 7 cases per 10, 000 discharges. 3. The incidence rate of nosocomial infection among patients of neurosurgery department was the highest(2,742 cases per 10,000 discharges). And the incidence rate of nosocomial infection was 6 times higher among the patients of intensive care unit than that of general ward. The reasons of higher nosocomial infection rate of intensive care unit and neurosurgery appeared to be due to many invasive procedures. Thus the priority in nosocomial infection control program must be given to those groups.

Dynamic strategy(DS) is a fast threshold algorithm for the Octopus 101 perimeter. To analyze the efficiency of DS, we compared the results of visual field measurements using DS and conventional normal strategy(NS). Subjects comprised 60 eyes of 30 normal individuals in the 3rd decade who has not experienced perimetry before. Program G2 was performed on all subjects at random and enough intervals between the two tests(more than 1 hour). Mean testing time was 1047.63+/-219.38 seconds in NS and 684.98+/-130.95 seconds in DS. Testing time reduction rate was 32.69+/-14.35% on average. Mean defect(MD) was 2.80+/-1.02dB, 2.15+/-0.94dB in the two strategies, respectively. Corrected loss variance(CLV) was 1.31+/-0.50dB2 and 1.03+/-0.61dB2 in each test. There was significant difference in MD and CLV statistically(P<0.01). Mean short term fluctuation(SF) was 1.38+/-0.49dB and 1.45+/-0.50 dB; mean reliability factor(RF) was 2.05+/-2.73% and 1.98+/-2.80% in the two strategies, respectively. There was no significant difference in SF and RF statistically(P>0.01). It took less time with DS than NS in Octopus 101 perimeter, but further study will be needed for clinical application of DS.

Study of filariasis to determine important factors involved in its ecology was carried out on Che Ju Island for three consecutive years from 1968 to 1970 in seven villages, three coastal villages and four islets remote from the main island. One village which was located in mountainous area far from the coast was surveyed to serve as control area. About 90% of population inhabiting the study area had at least one blood smear during the three-year period; about one third had three blood smears, and a little over one third had two, and the rest only one examination. Animal and mosquito surveys were carried out at the same period. Followings are the results obtained: All human cases but several had microfilariae identical to the description of B. malayi. The several cases who had morphologically different microfilariae from that of B. malayi need further study for definite conclusion. Five persons randomly sampled from Mf positives and bled every two hours demonstrated nocturnal periodicity between 9 p.m. and 3 a.m. Human is considered to be only reservoir host for human filariasis in the area since animal survey and experimental exposure to the infective larvae of human filaria species showed failure to infect animals. Microfilaria rate, microfilaria density, prevalence of elephantiasis varied by area and age with correlation, which indicated cumulative process of the parasite by repeated exposure and development of host immunity to certain extent. Clinical manifestation of filariasis (symptom complex and elephantiasis ) taken from history and inspection was low in its prevalence with range of 0.9% 11.8% of total population. Only 5.2% of 517 Mf positives had the clinical manifestation. 24.8% of 109 persons with clinical manifestation had microfilaria; 42.9% with symptom complex only, 23.1% with both symptoms and elephantiasis, and none with elephantiasis only were microfilaria positive. Ae. togoi was the only species infected with the filaria. Mosquito infection rate by area showed positive correlation to the Mf rate and density of human population; where the Mf rate and density were high, the mosquito infection rate also high.
