This study was planned to find out the most effective process, in regards of acceptability to the target population and possibility to detect the more cases, from various prossible processes for tuberculosis case finding, those processes were designed so as to give a opporlunity to take one sputum examination and one radiography when information was given through various channel.
This study has been done during Apr. 15 to May 17, 1969, and the objuctive population was whole over 20 years of age inhabitants in Mokpo city.
The results obtained were as follows;
1) Among the 65, 882 objective population, 9, 203 were responded to sputum examination(response rate 13.8%) and found 155 hacteriologically positive (positive rate 1.7%).
Number responded to X-ray mass survey was 10.197 (response rate 15.5%) and found suspects was 616(radiological suspect rate 6.0%).
2) Among sputum collection examination, s_(1) is the most effective to detect the more expected cases but required excessive manpower(case detect rate 0.30%). S_(2) is also effective in saving manpower and bigh case detect rate, but the difficulties are to get co-operation with "Banjang" and unclarity of the examince marked on specimen bottle collected by "Banjang.
3) Among X-ray mass survey, X_(2) is excellent in high response rate and high detect rate (19.0% and 1.2% respectively) compared with others.
4) Both in sputum collection examination and X-ray examination the case rate is higher in male and in older age group.
5) In the prevalence survey taken through the random sample of which 97.5% of target popultion was covered, the morbidity rate by X-ray finding was 5.0%, this is lower than that of the whole national rate (1965) 7.3%, in the same age group.
6) It was thought that the combination of S_(1) and X_(2) is recommendable as the best mass case fiding method in unban area.
7) Also it was suggested that to gain more participation to mass radiography, the adjustment of work time is inevitable, from 5 o´clock early morming till noon, etc, and the capability of microscopy was about 50 slides per day per trained personnel, and a health worker is able to visti and collect sputum about 40 to 50 households a day.
