본 조사에서는 서로 다른 주거환경에서 생활하는 집단군에 대해 셀로판테이프항문주위도말법으로 요충감염현황에 대하여 조사한 결과 다음과 같은 결론을 얻었다. 1) 국민학교 및 집단시설거주아동 2,966명을 조사하여 484명이 요충란 양성자로 나타나 16.3%의 양성률을 보였다. 2) 지역별 조사에서 대도시지역의 경우 총 1,144명을 조사하여 79명이 양성자로 나타나 6.9%의 양성률을 보였고, 농촌지역에서는 총 1,268명을 조사하여 193명이 양성자로 나타나 15.2%의 양성률을 보여 대도시지역보다 농촌지역에서 터 높은 감염양상을 보였다. 3) 남, 여별 조사에서는 남자, 1,528명을 조사하여 240명이 양성자로 나타나 15.7%의 양성률을 보였으며, 여자의 경우 1,438명을 조사하여 244명이 양성자로 나타나 16.9%의 양성률을 보여 남, 여별 감염률은 큰 차이를 타나내지 않았다. 4) 국민학교 아동의 학년별 조사성적을 보면 대도시지역 국민학교 아동의 경우 저학년에서 고학년으로 올라갈수록 감염률이 저하되었으나 농촌지역 국민학교 아동의 경우 감염률에 있어서 학년별로 현저한 차이를 나타내지 않았다. 5) 주거환경별 조사에서는 국민학교 아동 2,412명을 조사하여 272명이 양성자로 나타나 11.3%의 양성률을 보였고, 고아원(영아원, 육아원) 아동 416명을 조사하여 136명을 조사하여 76명이 양성자로 나타나 55.1%의 높은 양성률을 보여 국민학교보다 집단거주시설 아동에서 더 높은 감염양상을 보였다. An epidemiological study was undertaken to evaluate the prevalence of E. vermicularis infestation among children in primary schools and orphanages. A total of 2,966 children in primary schools and orphanages was examined for F. vermicularis by means of cellotape anal swab technique. The purpose of the present studies is to determine the prevalence of enterobiasis among children and to make a comparison with the rate of infestation by survey areas. The result could be summarized as follows : 1) The egg positive rate of cellotape anal swab method was 16.3% out of 2,966 children. 2) The egg positive rate of urban area was 6.9% out of 1,144 children and the egg positive rate of rural area was significantly higher than that of urban area. 3) The egg positive rate of boys and girls were 15.7% out of 1,528 children and 16.9% out of 1,438 children. 4) The egg positive rate of primary schools, orphanages and mental retardation child group was 11.3% (out of 2,412), 32.7% (out of 416) and 55.1% (out of 138) respectively. There was noted a tendency of decrease in prevalence by increase of the age.

In Korea, the position of health among the sectors of everyday life lies behind the others. The inhabitants don't consider health so important and immediate as food and shelter. Primarily, it seemed more important for them to eat something and to educate their children than to secure health. Under this situations we must take into consideration their health status and health problems in terms of the social system. Health cannot be maintaned by itself. It inter acts with a set of social conditions such as income, knowledge about health, health institution, health insurance, social class, culture and etc. But the community health projects which have carried out in Korea since the beginning of 1970s focused mainly on the medical care and medical delivery itself regardless the background of health care. According to the existing results of socio-epidemiological and medico-sociological researches, a set of social conditions has a great effect on the inhabitants' health status and health care. So, such conditions will be considered primarily in Korea University Health Project. This paper is prepared as a preliminary step for such a program. In this paper we mainly inquired into the relationship between health and the attitudes of inhabitants.

Face-to-face interviews were carried out to investigate the relationship between social networks and hypertension in 958 rural residents(males=440, females=518) aged 60-64 of a community-dwelling sample of Dalsung County from April to September in 1996. Eight elements of social network were measured : marital status, regular religious attendance, membership in groups, number of friends, relatives, siblings, children, grandchildren. Hypertensives were defined as meeting at least one of following criteria : hypertension history, systolic blood pressure more than 160 mmHg, diastolic blood pressure more than 95 mmHg. In univariate logistic regression for males, having 1-4 friends vs. none showed odds ratio 0.43 (95% Confidence interval CI 0.19-0.96) and having 2-3, 4 and more than 5 children had reduced prevalence of hypertension with odds ratios 0.21 (95% CI 0.06-0.72), 0.14 (95% CI 0.04-0.49), 0.24 (95% CI 0.07-0.82), respectively when compared with persons without children. In females, there was no elements of social network statistically significant. Having 5-9 grandchildren vs. none showed a marginally significant odds ratio 0.42. In multivariate logistic regression models for males with adjustment for age, education, body mass index, smoking and drinking, number of friends and children showed increased odds ratios and number of close relatives gained a statistically significant odds ratios (0.44-0.50). In females, the adjustment yielded little changes of odds ratios except number of grandchildren which gained a statistically significance. These results suggest that only a certain elements of social network may be associated with reduced risk of hypertension and they may be different between genders in rural resident aged 60-64.

The usage or agricultural chemicals is on the increasing tendency. Methyl bromide and organophosphate are the most widely used toxic agricultural chemicals in Korea. We try to set up the methods to detect the accumulation of these chemicals in Korean farmers. Blood samples were collected for 121 farmers of slack's season in February 1998. And survey about arable acreage and usage of the gloves and masks was also performed. Serum cholinesterase activities and bromide concentrations were measured with gold chloride method and colorimetric method. The reference ranges of serum cholinesterase activity and bromide concentration were 1.6~15.9 U/mL and below $72.9{\mu}g/mL$. Serum bromide concentrations of farmers and normal controls showed no differences. Serum cholinesterase activities of farmers were significantly higher than those of normal controls. According to the arable acreages and usage of the gloves and masks, serum bromide concentrations and cholinesterase activities showed no differences. In conclusion, serum cholinesterase activities and bromide concentrations showed no differences between farmers of slack's season and normal controls.

Paragonimus westermani is one of the most popular endemic parasitic diseases in Korea. The nation-wide prevalence survey were carried out by Gobayashi (1921) with sputum examination and by Walton and Chyu (1959) with the intradermal skin test respectively. Recent studies showed the decline of positive rate in intradermal skin test of the local inhabitants and also showed the less distribution of intermediate host. The fact seemed that caused by economic improvement of village people, decrease of intermediate host by increasing use of pesticides, becoming lower water level at streams and rivers and better irrigation and finally by better community health education etc. Gangwha area of Gyeonggi-Do was found out as an endemic area of Paragonimus westermani through some studies in the past, however, in the vicinity area of Gangwha, the study in Kyodong island (myon) was carried out in 1965 by Yun et al. Therefore author carried out the intradermal skin test for 2,380 students of primary, middle and high school in Kyodong island and Samsan island. The results showed as follows : 1) The positive rate of intradermal test for paragonimus westermani infection showed positive in 152 among 1,845 students (8.2%) in Kyodong island, and 21 among 637 students (3.3%) in Samsan island respectively. 2) According to grade levels, 49 among 973 students (5.0%) in primary school, 62 among 962 students (6.4%) in middle school and 53 among 445 students (11.9%) in high school showed positive rate. This showed the higher grade the higher positive rate. 3) Among these total 164 positive cases in the intradermal skin test, only in 3 cases eggs were found in sputum. 4) Finding out the intermediate host, only 28 crayfishes from Kyodong island and 12 from Samsan island were collected and examined for metacercaria infection, however, none of metacercaria was found. 5) As a control group, 2 primary schools from the main island were selected. In these schools from the sixth grade students showed positive rate of 4.8% in Naega primary school and 0% in Hajeom Primary school respectively. Those results showed much decrease than studies carried out in the past. 6) The survey for food habit showed that 15 among 1,274 students (1.2%) had experiences of eating raw intermediate host(crayfish) and 266 among 988 students (27.0%) ate cooked.

Toxocariasis is a parasitic zoonosis caused by infestation of humans with larvae of Toxocara canis, the common roundworm in dogs. Two syndromes have been identified : visceral larva migrans and ocular toxocariasis. In this study we were characterized proteinase activity in crude extracts from liver, lung, kidney and heart of mice infected with Toxocara canis and the dynamics of their changes in different stages of disease. The optimal pH was 5.5. In liver of mice infected with Toxocara canis, the maximun activity of proteinase was observed in 5 day post infection. In lung, the activity reached its maximun on 5th day in A group (infected with 100 embryonated eggs), and on 5th week in B group (infected with 50 embryonated eggs). In kidney, the maximum activity was shown at 6th week in A group, and in B group was shown at 10th day. In early infection, the activity reached its maximun in heart of mice infected with Toxocara canis. As we could see, the dynamics of the changes of proteinase activity in mice is similar in the case of the disease with other biochemical and immunological indices observed in toxocariasis.

Clonorchiasis sinensis is one of the most important endemic diseases in Korea, and this disease has been known to be one of public health concern in many areas of Korea. This survey was undertaken to evaluate the status of clonorchiasis in Yeoju Gun, Gyeong-gi Do from July to September 1980. A total of 1,194 male students were examined by intradermal test with Clonorchis antigen. In order to detect Clonorchis egg, the stool examinations were undertaken to 1,158 students, and the intensity of the Clonorchis infection was estimated by the Stoll's egg count. The prevalence rate was reanalyzed by the regional groups for an investigation of regional characteristics of infection. The following results were obtained in this survey. 1) Among 1,194 students in Yeoju Eup, positive rate of intradermal test with C. sinensis antigen was 17.2 percent. (middle school14.6% and high school 20.1%). 2) In the examination of 1,158 stool specimens, Clonorchis eggs were found in 97 (8.4%) cases. 3) Mean E.P.G. of Clonorchis infected case was $1,330{\pm}2,620$. 4) The degree of the intensity of Clonorchis infection by E.P.G. count was distributed as 73.6% in light infection (100-999), 22.6%, in moderate infection (1,000-9,999), and 3.8% in heavy infection (10,000-29,999). 5) High prevalence rate of Clonorchis sinensis was found in the Sang-Ri(9,3%) and Ha-Ri(8.4%) in Yeoju Eup. Neighbouring Bugnae Myun (11.5%), Gangcheon Myun(12.1%) and Neungseo Myun (11.1%) adjacent to the river had a similary high prevalence of C. sinensis.
