  • Seventy wild rats were caught from Seoul city, Kyonggi, Kangwon, Honam, and yongnam provinces. All of them were in same species, Rattus norvegicus, except two R rattus from Kyonggi province. Seventy sera from wild rats were studied by immunofluorescent antibody assay for evidence of infection by spotted fever group rickettsia. The antidody prevalance was 37.14%(26/70) for spotted fever group rickettsia. The sero-prevalence rates for spotted fever group rickettsia antibody was the hightest in Kyonggi province with 55.56%(10/18), yongnam province with 50.00%(10/20), Kangwon province with 25.00%(2/8), Seoul city with 18.75%(3/16), and Honam province with 12.50%(1/8). The sero-positive rates difference between sexes were higher in female with 46.15%(12/26) than in male with 31.81%(14/44) for spotted fever group rickettsia. Twenty six of 68 Rattus norvegicus with antibody for spotted fever group rickettsia were in subadult with 50.00%(6/12), young adult with 38.89%(7/18), middle-aged adult with 35.29%(6/17), and old adult with 33.33%(7/21). No antibody was detected from R rattus.

  • It is very important to investigate the sanitary chemical conditions of farmwaters used for cattle breeding in the dairy farms. For this purpose we examined pH, KMnO4 consumption, total hardness, chloride, sulfate, NH3-N, NO3-N, fluoride, lead, iron, manganese, cadmium, copper, zinc and chrome in the farmwaters sampled 2 times(spring and summer)in Choongcheongnam and Kangwon Province. The pH of farmwaters in Choongcheongnam and Kangwon Province was 6.49$\pm$0.09, 6.70$\pm$0.06, total hardness 90.21$\pm$7.07, 64.53$\pm$6.38 mg/ι, consumption of KMnO4 4.13$\pm$0.62, 4.34$\pm$0.26mg/ι, NO3-N 6.51$\pm$0.55, 3.61$\pm$0.58 mg/ι, chloride ion 20.51$\pm$1.99, 5.41$\pm$1.36 mg/ι and sulfate ion 6.61$\pm$1.02, 7.28$\pm$1.30 mg/ι, respectively. But NH3-N was scarcely detected. Fluoride, iron, lead, cadmium, zinc, manganese and chrome were not detected from the tested farmwaters. There was high significance between each other in total hardness, NO3-N, chloride ion and sulfate ion. There was regional and seasonal significance in only NO3-N but only regional significance in total hardness and chloride ion.

  • Fumonisin $B_{1}$ ($FB_{1}$) is hepatotoxic in all species, and initiator and promotor for hepatocarcinogenesis produced mainly by Fusarium moniliforme. This fungus is commonly natural contaminant of corn and other grains worldwide, and has been associated with animal and human diseases. In these study, natural occurrence of $FB_{1}$ was surveyed in 30 healthy domestic corn kernels in Chonbuk and Kangwon province, harvested in 1994 and intended for human consumption, and 15 imported American and Chinese samples of each, collected from different ship-loading at Inchon harbor for animal foodstuffs. $FB_{1}$ contents were measured by high-performance liquid chromatography (HPLC) with a fiourescence detector. The data revealed that 2 out of 12 corn kernels from Kangwon province with 1.1 and 0.7 ppm, and 2 out of 18 corns from Chonbuk province with 0.5 and 1.3 ppm, respectively. However, there was no detection of $FB_{1}$ in imported corn samples, even though those were visibly moldy.

  • Blueberry, which produces phenolic compounds, is one of the most popular fruits in Korea. During a survey on blueberry diseases, 16 Colletotrichum isolates were obtained from blueberry leaves in Chuncheon and Gosung, Kangwon province, Korea. Using morphological and molecular analyses, the isolates were identified as Colletotrichum aenigma, C. fioriniae, C. fructicola, C. gloeosporioides, and C. nymphaeae. C. gloeosporioides was the most frequently isolated (11 isolates), and only one or two isolates of the other species were found. After inoculation with all isolates, those leaves and fruits with wounds easily developed anthracnose; whereas, fruits without wounds became infected but leaves without wounds were infected by only two of C. gloeosporioides. Typically, around seven fungicidal agents are used to control anthracnose on blueberries in Korea. Fluzinam and prochloraz manganese complex strongly (over than 80%) inhibited the growth of all Colletotrichum species, while dithianon and mancozeb only weakly (about 80% or less) inhibited their growth.

  • This study was carried out to investigate the flora of indigenous habitat of Simjeok forest wetland, Mt. Jeombomg forest wetland, Mt. Sohwangbyung forest wetland, Jilmoi-neup, and Mt. Myeon forest wetland in Gangwon Province. The vascular plants were summarized as 547 taxa; 92 families, 296 genera, 468 species, 4 subspecies, 67 varieties, 8 forms. The plants that are specially noteworthy are 17 taxa of Korean endemic plants, 3 taxa of Critical Endangered Species (CR), 4 taxa of Endangered Species (EN), 8 taxa of Vulnerable Species (VU) and 17 taxa of Least Concemed Species (LC) in rare plants as categorized by the Korean Forest Service. Furthermore, V, IV, III degrees of floristic regional indicator plants as categorized by the Korean Ministry of Environment included 9 taxa, 14 taxa and 34 taxa, respectively. In addition, 25 taxa of naturalized plants were observed. In this study, we identified a variety of plants observed in the wetlands of Gangwon Province. We believe that this study will provide useful data for future research on the conservation and management of wetlands.

  • This survey was carried out to investigate the seroprevalence of antibodies to Neospora caninum in Korean native cattle (KNC) raised in Kangwon province in Korea. A total of 867 sera collected from KNC were tested for N. caninum antibodies using an indirect immunofluorescent antibody test (IFAT). One hundred and fifty five (17.9%) KNC were positive by IFAT. Seroprevalence of cows was 19.6% (44/224) and seroprevalence of boars was 17.3% (111/643). Among the seroprevalences of cattle according to the raised areas, five counties or cities, Hwacheon was 33.3% (1/3), Wonju was 30.8% (4/13), Chuncheon was 25.8% (24/93), Hongcheon 18.3% (22/120) and Wheongsung was 16.6%(104/628). It was proved that KNC raised in Kangwon provinces exposed extensively and seriously to N. caninum.

  • This survey was carried out to investigate the seroprevalence of antibodies to Neospora (N.) caninum in dairy cattle raised in Kangwon province in Korea. A total of 349 sera collected from dairy cattle were tested for N. caninum antibodies using an indirect immunofluorescent antibody test (IFAT). Ninety six (27.5%) dairy cattle were positive by IFAT. Seroprevalence of cows was 28.9% (91/315) and seroprevalence of boars was 14.7% (5/34). The seroprevalences of cows were increased according to the ages from 19.6% in cows less than 2 year-old to 50.0% in cows more than 7 year-old. Among the seroprevalences of cattle according to the raised areas, five counties or cities, Wheongsung was 34.6% (27/78), Wonju was 29.3% (46/157), Hongcheon was 28.9% (13/45), Chuncheon was 15.0% (3/20) and Cheolwon was 13.3% (2/15). It was proved that dairy cattle raised in Kangwon provinces exposed extensively and seriously to N. caninum.
