The possibility of using the dried powder form of Sarcodon aspratus fruitbody (a kind of mushrooms) as a meat tenderizer was explored in this study. The freeze-dried powder had higher protease activity compared to the hot air dried powder of S. aspratus. The powder kept higher activity when preserved at -20℃ than at ambient temperature. The hardness of the meat decreased and the cooking loss increased more rapidly when the meat was treated with the mushroom powder at ambient temperature than at -41℃. In terms of sensory evaluation, 0.1% of the powder based on the meat and 3 hours of treatment at 4℃ gave the highest acceptability score. In the comparison test, the meat was more acceptable when treated with the mushroom powder than with the imported commercial tenderizer. This led to the conclusion that it is quite feasible to develop a natural meat tenderizer using the Sarcodon aspratus fruitbody.

Soil microarthropods and heavy metal concentrations in the watershed soil of Hantan River, and water quality of streams were investigated. Heavy metal concentrations of the watershed soil was higher in Shincheon stream where the water quality was lover than the other investigated streams. And soil pH was lowest in the watershed of Shincheon stream. Especially, the concentration of Cr in the watershed soil of Shincheon stream was 2 to 3 times higher than the other investigated sites. Most abundant soil invertebrates were Acari and Collembola, whose proportion was over 90% in the total density. The density of soil invertebrate was much lower in the watershed soil than in the riverbank soil. Among the watershed soil sites, the density of soil invertebrates was lowest in the Shincheon stream which had the lowest water quality and higher concentration of heavy metals in its watershed soil. Biomass of Diptera and Coleoptera were higher in the watershed soils than in the riverbank soils. In the watershed soil of Shincheon stream the biomass of Diptera was much more prominent.
