In order to clarify the contamination of vegetable gardens with human intestinal helminths, the soil samples were examined for the presence of eggs and larvae during the period from September 1973 to August l974. When soil samples collected from the vegetable gardens in Taegu were examined, four species of helminth eggs (ascarid, whipworm, hookworm and liver fluke) and a number of unknown eggs were found. Ascarid was found to be highest in the rate of detection(82.5 percent), followed by whipworm. The rates of hookworm, liver fuke and Trichostrongylus species were unexpectedly low. There was no difference between detection rate of vegetable gardens and that of vinyl green houses. However, the average number of helminth eggs detected from the soil of vinyl green houses was higher than the number of vegetable gardens. In the monthly incidence of ascarid eggs, the highest rate was found in September, and the least often was observed in August. While, the peak in the average number of the egg was encountered in August. There was no distinct trend in the monthly incidence of whipworm. However, it is likely that the detection number of whipworm per 100 gm of soil examined was relatively abundant in a period from May to August, and very little from October to April of next year. When the soil of vegetable gardens was divided into superficial, intermediate and deep layers and examined for presence of ascarid egg. The average number of the eggs found of the superficial layer was more abundant than those of the intermediate and deep layers, but the rate for the former was similar with the latter. In the demonstration of larval nematodes from the soil of vegetable gardens and vinyl houses, there found the filariform and rhabditoid larvae of hookworm and the larvae of Trichostrongylus species and unknown one. The majority of the larvae detected was belonged to unknown species, followed by hookworm larvae. The least was found in the rate of Trichostrongylus species. Generally, the filariform larva of hookwom could be detected during the hot season from May to August, but no larva was found in the winter. This suggests that the soil of vegetable gardens and vinyl green houses in Taegu is contaminated with human intestinal helminths.

7.Observation on Neck Form Changes Related to Aging in Men (Part ll) - by the Neck Surface Changes Using the Tape Method.

As a mean to get a better understanding of the kind of form changes to which is subject the neck of the men in their aging process, replicas of neck surfaces were made on 9 subjects (3 in their twenties, 3 in their forties and 3 in their sixties) using the tape method. Three positions of the neck were taken in account : 1) normal position 2) right turn position 3) bent forward position. Measurements of the developed tape replicas have given us the following results : 1. Shapes of the different developed replicas ; Developed replicas of the elder subject show a more curved shape than the replica of the middle age subject, the younger subject having its neck base line the least curved. 2. Surface Area Changes ; In normal position, the neck replica of the elder group covers a smaller surface (average 163.7cm2) than the corresponding one of the younger group (average 193.5cm3). The bent forward position, increases the back surface of the neck in a percentage ranging from 19% to 26% without any major differences between the 3 age groups. The front neck surface being decreased at the same time we verified that the total surface compared to the normal position, had not increased.
