  • The prevalence of Intestinal parasite Infections In Inhabitants at the reaches of the Hantan River, Chorwon-gun, Korea, was observed from August 12 to September 14, 1993. Of 465 people observed by cellophane thick smear and formalin-ether concentration method, 2 Ascots lumbricoides (unfertilized), 1 Trichwis Dichturn, 39 Clonorchis sinensis and 16 Metagonimus egg positive cases were found. After treatment, the Metogonimus egg positive cases passed out flukes of Metogonimus Mlyata type. Of 68 fish caught In the Hantan River, 14 (20.6%) were Infected with metacercanae of Metogontmn, while no metacercana of C. sinenis was found. At this area, soul-transmitted nematodes are very low, but clonorchlasis and metagonlmlasis are prevalent by modernate endemicity.

  • Diatomite, bentonite and zeolite were used as porous materials for fabricating hygroscopic panels. Moisture adsorption and desorption of porous materials were investigated and hydrothermal method was applied to fabricate panels. Cheolwon diatomite and Pohang zeolite showed excellent characteristics of moisture adsorption and desorption. These characteristics were caused by higher surface area and pore volume of porous materials. Moisture adsorption contents were influenced by surface area and pore volume of panels, and surface area more effected on moisture adsorption. Moisture adsorption content of panel with 10% Pohang zeolite was 180g/m$^2$and that of 10% Cheolwon diatomite was 170g/m$^2$. Moisture desorption content of panel with 10% Pohang zeolite was 105g/m$^2$. Moisture adsorption contents of panel with porous materials were higher than that of panel without porous materials.
