A Study on the Water Pollution of Mountain Wells around Seoul Area / 예방의학회지

Mountain Wells are very important water source of the most the climbers in Seoul area. But the facilities around the wells are not modernized to prevent from contamination of microorganism and the other pollutants. We focussed our intention on the detection of some harmful chemical ingredients and contaminants. A total of 58 wells were examined according to the Standard Methods(APHA) and the following results were obtained : 1) Among the examined 58 wells, only 10 wells adequate to the drinking water standard, 2) 7.9mg of liberated CO2 was found in the Tchun-Ho-Dong Mineral Well, 3) Chemically harmful ingredients were not found, 4) The Mountain Wells were contaminated by Coliform Groups as many as 18 times than rural well.

A Study on the Physical Growth and Health Status of the Freshmen in a Private University / 예방의학회지

For the purpose of ascertaining the status of physical growth and health status of the University students, an intensive survey was conducted by the authors towards a total of 1,250 (Male 792, Female 458) who passed the written entrance examination at the Kyung Hee University in 1972. The items included the measurements on physical growth, various physical and nutritional indices, status of visual distourbance, dental status and tuberculosis. The findings and results can be summarized as follows ; 1. Physical Growth and Development. i) The average of body height by anthropometric was 169.39+/-5.05cm in male and 157.45+/-4.43cm in female. ii) The averages of body weight by sex were 59.42+/-6.47Kg and 51.81+/-5.21Kg, respectively. iii) The averages of chest-girth were 87.18+/-5.30cm and 80.51+/-4.53cm. iv) The averages of sitting-height were 92.21+/-2.79cm and 86.28+/-2.57cm. In all cases the male measurements were higher than female. 2. Various ludices about Physical Growth and Development; i) Relative body weight by sex were 35.08and 32.91, relative chestgirth 51.47 and 51.13, and relative sitting-height 54.43, 54.79, respectively. ii) Rohrer index was 1.222 in males and 1.327 in females, Kaup index 2.071 and 2.089, Verveck index 86.54 and 84.04, and Pelidisi index 91.15 and 93.08, respectively. 3. Status of visual distourbance. The vision of the students under 0.8 with Landolt's testing chart was 45.4% in left eye and 46.6% in right eye (male : 44.4% and 45.7%, female : 47.2% and 48.0%), while under 0.6in both visions was 41.0% and 40.5% (male 40.8% and 40.7%, female : 41.5% and 40.2%),respectively. 4. Dental Status. Out of total 19.4% (male 19.2%, female 19.6%) had gingivitis, the female incidence rate of gingivitis was higher than male. Average number of teeth in each subjects was 29.6 teeth; male had 29.9 teeth and female had 29.1 teeth. The caries rate was 78.9%(male 75.6%, female 84.5%), the female caries rate was higher than male. The average number of i) Caries per tooth rate was 8.5% in male and 9.2% in female, ii) Missing per tooth rate was 0.3% and 0.2%, iii) Filling per tooth rate was 3.9% and 4.2%, in all cases, the female incidences were higher than the male. The average number of D.M.F. was 3.8 teeth in male and 4.0 teeth in female, female was higher than male. The average rate of D.M.F. was 12.7% in male and 13.7 in female, female was higher than male. 5. Pulmonary infiltration. Among the total, 53 students were diagnosed as pulmonary infiltration (tuberculosis), of whom 51 were minimal cases, one were moderately advanced case and one were far advanced case.

A Study on Status of Birth and Death in an Urban Area / 예방의학회지

A survey was conducted by the staff of the Dept. of Preventive Medicine, Kyung Hee University, School of Medicine, from April through May 1971, on such events as delivery, death, abortion and family planning. The survey directed to a total population 6,552 (Male 3,133; Female 3,419) residing in this area (1,262 households) led us to the following findings : 1) Two year averages of crude birth rate, crude death rate and natural increase rates were 24.9, 5.0 and 19.9 respectively. 2) Infant death rates for the years 1969 and 1970 were 13.2 and 5.8 respectively, mean for the two year period being 9.3. 3) Hospital deliveries rated 68.5 percent, Home deliveries 28.4 percent and deliveries at midwives' offices 2.7 percent. 4) Deliveries other than hospital and midwives' office deliveries were found to be attended more often by mothers. 5) About 41.4 percent of all pregnant women during last two years received prenatal care once or more. 6) The induced abortion rate was 6.7 percent in 1969 and 7.5 percent in 1970. 7) The spontaneous abortion rate was 1.1 percent in 1969 and 1.4 percent in 1970. 8) Hypertension was the most frequent cause of adult death(21.6%). 9) The rate of current practice in family planning was 43.3 percent of all women.

Studies on Fluorine Compounds among the Air Pollutants / 예방의학회지

This study was conducted by the Dept. of Preventive Medicine, Kyung-Hee University, School of Medicine as a preliminay test for the effects of Fluorine Compounds to the Plants from April through August, 1971. Fluorine was measured with Zirconium-Alizarine method and the following findings could be obtained : 1. Most high densities (25.7pptm) was found around the industrial areas and lowest (19.3pptm) around residential sections in Seoul. 2. Average density of Fluorine in the atmosphere of Seoul City was 22.3 pptm which can damage such plants as Pine, Strawberry, Peach and Grapes. 3. Fluorine contests (22.3pptm) in Seoul area atmosphere of shows about 4 times more than that of Cincinnati, Ohio, U.S.A.
