  • The effects of various fractions from the aerial parts of Echinosophora koreensis Nakai on the antimutagenic and the immuno-regulating activities were evaluated by in vivo bone-marrow micronucleus test and HA titer reaction. No significant suppressive effects of these extracts and echinoisosophoranone were shown on cyclophosphamide-induced micronuclei, but HA titers were significantly enhanced in ether and BuOH extract treated-group. Tetracosanol and docosanol were isolated from the ether extract of this plant.

  • The paper studies on the site and space composition of Lee Ha-Bock's traditional thatched roof house. The house is located at a site with back to the mountain and facing the water and the rear and front mountains formulate a shape of Myungeonhyung(a sleeping dog figure) with HyungGug theory of Pungsu. The house has ㄱ shaped Anchae, ㅡ shaped Sarangchae and Gwangchae. Those are formulate ㅁ lay out followed the land form. Through the research I found the house shows a typical traditional farmhouse in the middle of Korea of Josen period. Nowadays there are many large Giwajip(tile roofed house) of Josen period is remained but only a few thatched-roof house is lived. In this situation, the house has considerable architectural values as a traditional thatched roof house.

  • The fall-of-potential method is commonly used in measuring the ground resistance of large-scaled grounding system and the current and potential auxiliary electrodes are horizontally arranged. Because the distances between the ground grid to be tested and auxiliary electrodes are limited in downtown areas, it is very difficult to measure accurately the ground resistance of large-scaled grounding system. In this paper, the fall-of-potential method of measuring the ground resistance with the vertically-placed current and potential auxiliary electrodes was examined and discussed. The validity and good accuracy of the proposed method of measuring the ground resistance were confirmed through various simulations and actual tests carried out in uniform and two-layer soil structures.
