Abstract PDF: A study was carried out from October 1977 to September 1978 in order to develop health care deliverly system which will meet to rural area in Korea. For the study objective a model of health care delivery system of Myun (township) area was developed which is adopted the net-work of village health voluntary worker who will play the role of bridge for communication related with health and illness between families or village people and health subcenter, and the model health care delivery system net-work was set in the area of Soodong Myun, Yangju Gun, which is the rural health demonstration area of Ewha Women's University since 1972. The activities and attitude of 22 village health voluntary workers were observed and analyzed during the study period. The results are as follows; 1. For the field activities of village health voluntary workers, a guide line which is described with specific behavioral objectives was developed and used for not only training of the workers but also evaluation of their field activities. 2. During the study period, the number of 971 village people were served primary health care service by village health voluntary worker and the service was classified largely into symptomatic medications (92%) and preventive measure (8%). 3. Comparative percentage of the number of 894 symptomatic cases cared by village health voluntary workers to 5,695 cases of patient treated by Soodong Health Subcenter during the same period was 15.7%. 4. Annual utility rate of village health voluntary worker by Myun total people was 16.1% but utility rate by Rie was varied from 38.2% to 2.8% which shown there were considerable difference in each Rie. In order to settle the village health care service, the obstructive factors of utility should be detected and their counter measure must be taken. 5. As the health need of village people increases, it is expected that the supplement of drug excluding present six basic drugs is inevitable, but considering the ability of village health voluntary worker, the selection of additional drugs and education, plan should be carefully studied. 6. It is desirable that a financial resource for supplementary purchase of first aid kit, drugs and materials should be alloted from village public fund like Saemaeul Women's Club fund, which has already practiced in a few villages in the study area. 7. As pointed out by village health voluntary workers, in order to improve the village health, village leaders should be in the center of it and the cooperation of whole village people is a core of healthful village development, and it is reasonable that the health subcenter backs up these voluntary health activities by village people in techniques. 8. It seems effective that a supplementary education for village health voluntary worker be accomplished by a planned education through regular meetings like worker's monthly meeting and irregular post guide when Myun Health Workers can handle the problems found during the round trip of villages. 9. It is desirable that village health voluntary workers, who are recommended by a civil voluntary organization like Saemael Woman's Club, are charged by natural village unit, are given a function of village health care service and used through basic education at health subcenter. 10. It is advisable that the village health voluntary worker's service is compensated not by a form of money, but by other way such as an exemption of medical fee of worker herself or her families in health subcenter can be one method. 11. Daily health activities of each village health voluntary worker should be reported to health subcenter by biweekly or monthly in order to get not only for basic data of the program but also for evaluation the program. It is recommendable that the report form should be simple and clear enough for village health voluntary worker to fill it effectively. 12. Village health care service should be developed into a Saemaeul Movement in which village people actively participate. For this, the appointed function of village health voluntary worker should be absorbed into those of living Environment Betterment Section or Family Planning Section of Saemaeul Women's Club or it is desirable that establish a new section, Village Health Promoting Section and made it involve the appointed functions of those sections mentioned above.; Summary

Abstract PDF: This study was conducted to find out the most suitable weight-height index out of the weight/height(p)-type indices that could be used for the evaluation of nutritional status in an epidemiological survey and for the screening of the obesity. The subjects were chosen randomly, 2,182 males and 719 females from college students and office workers in Seoul districts. The 'best' power-type weight-height index for Korean men and women of all ages from 16 to 59 was found to be weight-height(1.54) for males and weight-height(1.42) for females. Weight-height(2)(Kaup index), however, was the best suited weight-height index for each age group of both sexes except that relative weight (weight-height) was considered to be desirable to apply for males of teen-aged and of over fifties and for females of over forties of age. Normal ranges of Kaup index values for males and females of each age group were presented in tables 5 and 6. These findings suggest that Korean are generally leaner than other ethnic groups of the same sex and age.; Summary

Abstract PDF: In order to investigate air pollution by heavy metals in Seoul city, the suspended particulates in the atmosphere were sampled with high volume air sampler in industrial area(Ku Ro Dong), commercial(Kwang Hwa Moon) and residential(Shin Chon Dong) from January to November, 1977. The sampled suspended particulates were digested and extracted from suspended particulates with the acidic solution by reflux-extraction technique, and were measured by atomic absorption spectrophotometry. And Mercury was measured by mercury analyzer applying the reducing sublimation technique. Among heavy metals analyzed, the iron was identified at th highest level in the suspended particulates and the chromium was the least. Through the surveyed area, the concentration of heavy metals of the industrial area was comparatively high among others and the commercial was the second. It was detected that lead was the most concentrated in the suspended particulate of the commercial area, that might be caused of the traffic emissions. The seasonal variations were analyzed and the correlations among heavy metals and total suspended particulate were also calculated. Especially, the iron was highly correlated with total suspended particulate in all the surveyed areas.; Summary

The following results were obtained. 1. Of the housewives studied, 61.5% knew that B.C.G. is a vaccine for T.B. prevention and 12.3% knew that D.P.T. is a vaccine for diphtheria, pertussis, and tetanus. 2. The vaccination rate of the children under six-year of the housewives studied was : polio 83.1%, B.C.G. 75.4%, D.P.T. 66.2%, and measles 55.4% respectively. 3. The vaccination rate was higher in children in the area near from the health subcenter than in those of the area further away. 4. Out of 87 respondants, 87.5% knew one or more methods of contraception for spacing children. These were ; loop 69.0%, oral pill 66.7% and condom 14.9% respectively. 5. Out of 87 respondants, 82.2% knew the methods of contraception for sterilization. These were : laparascopy 87.5% and vasectomy 16.9%. 6. Out of 87 respondants those who had experience using contraceptive methods were 70.1% and present users were 47.1%. 7. Contraception practice rate was higher in the group of housewives having middle school education or above than those having primary school education or less. 8. Functions of the health subcenter listed by respondents were : patients care 72.4%, family planning 31.0%, vaccination 23.0%, T.B. control 3.4%, health education 3.4%, infant birth delivery assistance 1.1% respectively. 9.
