    This attempts was made to analyse by applying the methods of the variation comparison and correlation analysis for 32 structural indices concerned 23 villages in Iwate-Ken during 10 years from 1960 to 1970 on the base of 5 years', 3 years' average and a year in accordance with the characteristics of indices. The groups of structural indices were classf ied 3 groups of the health with 11 indices, agricultural with 9 indices, and social with 12 indices. According to the results of this study, the group with the lowest variation of indices was agricultural structure accepted as? significant with all positive rates on the rank correlation relationship of indices between 1960 and 1970. The next group was social structure and the group of health structure had the highest variation among 3 groups. The ratio of items accepted as significant of the rank correlation for the mutual items ofjndices in 1960 was 31.8% for total items, and the ratio in 1970 was 18.8%. The number of indices items accepted as significant in company with 1960 in 1970 was 60 items and this ratio was 6.1% for total items. The feature of village structure was found a tendency to take the higher mortality rates with higher birth rates in 1960, and also the index of infant mortality rate and the other maternal children health indices had the very important view points of analysis for villege structures. In 1970, the feature had a tendency with relation of mortality in connection with the chronic diseases for the elderly people, so called, cerebral vascular disease and hypertension, cancer and heart disease. The village structures were divided 2 major structural zone of rice bowl and farm as the results of indices analysis. Although the zone of rice bowl had a feature of high mortality rate for the elderly people, the level of medical services and finance of villages was higher than the level of farm zone. The farm zone had not only a feature of higher birth rates, but also the relative lower level for social structure within 23 villages. But the mortality of cerebral vascular disease and hypertension had even though increased at the farm zone in 1970. The results classf ied on similar types of ranking 23 villages on the base of indices linkages with highly significant correlation both 1960 and 1970 were f ormd 3 types of classification accepted the system area of Kitakami mountains, Kitakami plain area and the other neigboured area. The level of 23 villages structures was founded that the lowest level was the Kitakami mountains area mostly appropriated with the farm zone and the highest level was Kitakami plain area nearly appropriated with the zone of rice bowl and the other neigboured area was an intermediate rank.

    Biologic and serologic properties of Escherichia coli strains isolated concurrently from the urine and stool in 63 cases of urinary tract infections were studied with the findings as follows ; (1) Type O E. coli isolates from the urine included nine different serotypes : 1, 4, 6, 7, 14, 19, 21, 28 and 75, whereas those obtained from the feces showed fourteen serotypes, i. e. 1, 2, 4, 6, 7, 8, 11, 14, 15, 19, 28, 40, 75 and 80.(2) Types O-4 and O-6 were conspicuously frequent, accounting respectively for 19.3 and 35.4 % of all the serologically identifiable isolates from the urine.(3) The most frequent serotype among all the serologically identified fecal isolates was O-2, accounting only for 13.1 % ; hence moreover low rates for the remaining 13 types.(4) Among the pairs of E, coli isolates obtained concurrently from the urine and stool in 41 cases, 17.0 % proved to be serologically identical.(5) Antibiotic sensitivity tests conducted by the dilution technique revealed that 61.9 of the urinary isolates and 41.4% of the fecal isolates were resistant to chloramphenicol, streptomycin and tetracycline, showing MIC values over 50mcg per ml .(6) A little more than a half of the urinary isolates, 51.4 %, were hemolytic for humanred cells whilst only 12.1 % of the stool isolates proved to have such activity .(7) The hemolytic activity for human erythrocytes was demonstrable with 82.3 % of types O-4 and O-6 isolates from the urine. The corresponding ratio with the same serotype population from the stool was as low as 33.3 %.(8) Sixty-eight and a half percent of the urinary isolates and only 24.2 % of the fecal isolates were found to cause hemolysis of sheep red blood cells.(9) The De-tests with lapine intestine in vitro were positive with 27.6 % of the urinary isolates and with 5.0 % of the fecal isolates.(10) Of the types O-4 and O-6 isolates from the urine, 46.1%were demonstrated to show positive De-tests whereas none of the isolates of the same serotypes from the stool proved to give a positive De-tests.

    The population growth in Okinawa Prefecture is classified into three phases as a whole, i. e. a stagnation from 1920 to 1944, an upheaval due to the cease of World War II, and a diversification among regions after 1950. The diversification after 1950 is restatable as the rapid growth of urban populations and the stagnation or decrease of rural or small islands populations. The distance from the central part of population increase to each administrative regions has been related to the pattern of population growth in each regions, and as such centers, three areas; urbanized area in central and southern parts of Okinawa Island, Hirara City and its neighbour, and Ishigaki City, are denoted.
