Five dictyostelid cellualr slime molds were found in forests of Pinus densiflora and Quercus mongolica in Mt. Surak, uijeongbu, Kyunggi-do, South Korea. isolates were Polysphondylium pallidum, Dictystelium firibasis, D. crassicaule, P. tennuissimum and D. valenstemmum. Dominant soecies was P. pallidum. This species had occurred widely in South Korea as well as in the world. Especially, new dictyostelid, D. valenstemmum shim et Chang, was found in the fermentation layer of P. densiflora and Q. mongolica mixed-forest soils. D. firmibasis had not been described until now and found in the mountain forests.

The investigation was cycle of aluminum of surface soil elements in dynamic grassland ecosystems at a steady state in a Zoysia japonica and a Miscanthus sinensis ecosystem in Mt. Kwanak, Korea. Average amounts of total storage for aluminum in Z japonica and M. sinensis grasslands were 8,426mg /$m^2$ and 7,849mg /$m^2$ respectively. Decay constants estimated on the base of experimental and mathematical model, were 0.04 in Z japonica grassland, and 0.08 in M. sinensis grassland. Half time to decay aluminum of litter soils were 17.33 years in Z japonica grass-land, and 8.66 years in Al. sinensis grassland. 95% decay times in Z japonica, and in M. sinensis grassland were 75.0 years and 35.0 years respectively. Needed times to lose almost all of elements in Z japonica and M. sinensis grassland were 125.0 years, and 62.50 years respectively. The metals were losed more rapidly in M. sinensis than in Z japonica grassland. The cycle of aluminum was investigated to be related with soil acidity. Key words: Cycle of aluminum, Zoysia japonica. Miscanthus sinensis, Mt. Kwanak, Decay constants, Soil acidity.

The purpose of this study was to examine the elementary and secondary school pre-service teachers' perceptions about life science. The instrument consists of three domains. Data were collected from 154 pre-service teachers(elementary: 55, secondary: 99 and male: 60, female: 94). Quite a few elementary and secondary pre-service teachers had unbiological perception about the meaning of life. Even though there were no difference between male and female pre-service teachers, more elementary pre-service teachers had unbiological view about it than secondary ones. Most of secondary and elementary pre-service biology teachers had the highest interest in genetics and human metabolism. Topics that they want to know is related to biotechnology. It was investigated that topics related to biotechnology and evolution were what they wanted to know about.

This study was carried out to investigate occurrence and distribution of cellular slime molds by vegetation in Mt. Seorak. Eleven species were isolated from surface soil samples as follows: P. violaceum, P. candidum, P. purpureum, D. brefeldianum, D. minutum, D. delicatm, D. crassicaule, D. macrocephalum, D. firmibasis, D. polycephalum and D. implicatum. The dorminant species was D. brefeldinum. D. delicatum, D. implicatum, D. polycephalum and P. candidum of them were isolated rarely in Korea. It can be thought that these results were caused by characteristics of forest zone and geographical condition which Mt. Seorak is located at east side of central areas of Korea.
