A severe down mildew of Astragalus membranaceus occurred in Gangwon province in 1999 and 2000. Symptoms developed on young leaves and shoots, showing grayish white mycelium on the lower leaves. The infected plants had reduced internodes and twisted leaflets when the disease was severe. Peronospora trifoliorum was identified as the causal agent of the disease based on mycological characteristics. Pathogenicity of the fungus was confirmed by artificial inoculation. This is the first record of downy mildew on astrgal plant caused by Peronospora trifoliorum in Korea.

Three sediment traps were placed at the toe of sloping fields in the alpine belt of Korea and sediment removal efficiency was estimated. Soil texture of the site was sandy soil and 5 runoff and sediment events were observed during 2002. Sediment was largely affected by both the amount and intensity of rainfall. Especially, rainfall intensity seemed to have profound effect on sediment yield from sloping sandy fields. Sediment removal of the sediments ranged widely from 266 kg/ha to 16,974 kg/ha depending on tillage method, slope and slope length, and amount and intensity of rainfall. Sediment removal efficiency was estimated to be more than 98.8%. It was suggested that rational combination of sediment trap and drainage channel might well contribute to control sediment discharge from alpine sloping fields.

The highest degree of callus formation was obtained from the shoot tips of Dianthus superbus when cultured on the MS medium supplemented with 2.0 mg/L NAA and 0.5 mg/L BAP. Embryogenic calluses were obtained from the seperated friable calluses on MS medium containing 2.0 mg/L 2,4-D after 7-8 wk of culture. For plant regeneration, embryogenic calluses were selected and cultured on te proliferation medium. After 3 wk, somatic embryos appeared on MSK medium (0.5 mg/L NAA, 2.0 mg/L kinetin) and N6 medium (2.0 mg/L kinetin, 0.1 mg/LNAA, 0.1 mg/L 2,4-D and 2.0 g/L casein hydrolysate). When these somatic embryos were kept under continuous illumination, shoots were successfully regenerated on the both media. The shoots were rooted on MS medium supplemented with 2.0 mg/L NAA.

This study was undertaken to evaluate the effect of legume reseeding on legume establishment, dry matter yield, quality and botanical composition of grasses in timothy(Ph1eum prarense L.) dominated pasture at alpine area. Establishment number and percentage of legume in timothy dominated pasture were increased with spring, red clover(Tr$olium pratense L.) and gramoxone $treatment Dry matter yield of pasture was increased with fall and grazing after overseeding, but, there waq no difference in legume species. Crude protein content(%) of grasses at the first cutting was increased with red clover and paraquat (gramoxone) treatment. Based on the results, it is suggested that spring in seeding time, red clover in legume species and oveneeding after gramoxone treatment are good for effective renovation of timothy dominated pasture at alpine area.

This study examined the multi-functionality of an eco-pastoral system in alpine grassland and measured its economic value. The multi-functionality can be divided into three categories: direct-use value, indirect-use value, and heritage value. Direct-use value includes both extractive (forage and livestock production) and non-extractive (recreation and tourism) functions. Indirect-use value includes the functions of water conservation, soil erosion control, atmospheric control, landscape, livestock-manure management, and forest firebreaks. The heritage value includes the function of species diversity. The results showed that the annual value for 1 hectare of the eco-pastoral system in alpine grassland's direct use was estimated to be 21,090,874 Korean won; the indirect-use value was 15,562,203 won when the landscape in grassland system, and 16,018,224 won when the landscape comprised in silvopastoral system. The value of the species diversity in heritage terms ranged from 767,273 to 1,578,845 won, depending on whether it included any endangered species. The total value of multi-functionality of the eco-pastoral system in alpine grassland was estimated to be a minimum of 37,420,350 won/ha and a maximum of 38,687,942 won/ha. The results of this study can provide useful insights for the eco-pastoral system in alpine grassland policies in Republic of Korea.

The purpose of this study is to adopt qualitative research methods for alpine snowboard athlete to analyze their injury factors in depth from a psychological perspective. Therefore, in-depth interviews were conducted on four outstanding Alpine Snowboard athlete, and the results were as follows. Among the factors of the injury of Alpine snowboard athlete, the psychological point of view was derived from five factors: 'Trait Anxiety', 'Personality Characteristic', 'Expectancies of Significant Others, 'Discrepancy between ability and expectation' and 'Trauma Injuries'. The five psychological injury factors have expressed the raw data of the subject in a case-oriented manner, and empirical and field-oriented interview data will enable in-depth analysis of psychological factors related to injury to future Alpine snowboard athlete and coaches. It is expected to be used as a basis for injury prevention and countermeasures. All data can be used as a basis for positive effects on the quality of life of athletes and athletes in winter sports.

Pasture establishment techniques successfully employed in the alpine region of Korea are outlined. The subsequent management of the mixed grass/legume pasture to maintain a high producing sward is also described. Relevant overseas literature has been reviewed and related to the methods in use at the ROK/NZ Beef Farming Research and Demonstration Project in the alpine region of Kangweon-do.
