TL;DR: In this paper, a method of designing several rows of stabilizing piles to prevent a large landslide has been investigated, where the ground conditions of a slope are fixed, and the selections of the fixity condition of pile head, the number of pile rows, the position of piles rows, and pile length above sliding surface are carried out, followed by the systematic selections of factors of mobilization of lateral force, pile diameters, intervals between piles, and piles stiffnesses.

TL;DR: To evaluate the status of intestinal protozoan infections in inhabitants of Gangweon-Do, Korea, a total of 1,310 stool specimens was collected from 2 cities and 3 counties and the highest positive rate was found in 20-29 age group.
Abstract: To evaluate the status of intestinal protozoan infections in inhabitants of Gangweon-Do, Korea, a total of 1,310 stool specimens (male 669, female 641) was collected from 2 cities and 3 counties. They were examined routinely 1 time by the method of formalin-ether sedimentation technique. The results were as follows: 1. The positive rate for any kind of the intestinal protozoan cysts was 8.9 %. 2. A total of 6 kinds of the intestinal protozoan cysts were detected. The prevalence rate of each protozoa were; E. histolytica 0.8 %, E. coli 7.6 %, E. nana 1.4 %, I. butschlii 0.2 %, G. lamblia 0.5 % and C. mesnili 0.5 %. 3. Sogcho-city showed the highest positive rate as 15.2 %, Myeongju county was the next as 11.3 % and Weonju-city showed the lowest positive rate as low as 3.9 %. 4. By age, the highest positive rate was found in 20-29 age group(12.4 %). Female (9.5 %) showed a slight higher positive rate than male (8.4 %).
