  • We selected eight resistant cultivars including 'Heukryongsamcheok', 'Heukgeumsolsamcheok' and 'Gangryeoksamcheok' showing high suppressive effect against cucumber downy mildew (CDM) through plastic film house and field trials in spring and autumn season in 2015. Of them, these three varieties, 'Heukryongsamcheok', 'Heukgeumsolsamcheok' and 'Gangryeoksamcheok' were used to evaluated suppressive effect against CDM by comparing disease severity (area under disease development progress curve, AUDPC) with those of three susceptible varieties under plastic film house condition. AUDPC of three resistant cultivars was in the range of 10.9 to 23.6, meanwhile those of three susceptible cultivars was in the range of 286.7 to 290.3. Consequently, we confirmed that cultivation of the selected resistant cultivars can reduce CDM in vivo. When disease severity (diseased leaf area) was investigated on a resistant cultivar ('Heukryongsamcheok') sprayed without any organic materials and susceptible cultivars sprayed single-, two times- and three times with Bordeaux mixture, sulfur-loess mixture and $Kocide^R$ (copper hydroxide), respectively, it was the lowest in the resistant cultivar plot compared to susceptible cultivar plots sprayed with any organic materials. In addition, we evaluated control effect of the selected resistant cultivar by comparing that of organic materials including lime sulfur mixture, Bordeaux mixture and garlic extract. As a result, Bordeaux mixture showed the highest control effect against CDM. AUDPC of Bordeaux mixture, resistant cultivar, lime sulfur, garlic extract and untreated control was 3.9, 10.6, 95.6, 24.9, and 258.7, respectively. Based on the above-mentioned results, we think that the resistant cultivars and Bordeaux mixture can be effectively used to control CDM as one of control measures under the farmhouse condition.

  • Landslides induced by heavy rainfall from typhoon 'Rusa' in 2002 and typhoon 'Meami' in 2003 were investigated at Samcheok area, and the relationship between landslides and rainfall on that area was analyzed. The average annual rainfall at Samcheok area is generally $1,200mm\~1,300mm$. However, the average annual rainfall at samcheok for 2003 and ton was increased more than 2,000mm because of typhoon 'Rusa' and typhoon 'Meami'. The number of landslides and the landslides area are largely occurred in a area of the relatively high maximum hourly rainfall and 2days cumulative rainfall. Therefore, it confirmed that landslides are directly depended on the hourly rainfall and the cumulative rainfall. The landslides at Samcheok area induced by heavy rainfall due to typhoon are more influenced by the maximum hourly rainfall at the landslide occurrence day. In order to predict a rational landslide size, a new method included the maximum hourly rainfall and the landslide area in a traditional way was proposed. As the result of applying the new proposed method, the landslide size at Samcheok area is involved in the large scale landslide.

  • 삼척시 산불(1991년~2011년) 21년간 73건에 대하여 원인별로 분석한 결과이 입산자에 의한 산불이 42건으로 가장 많았으며, 연도별 산불발생은 2000년에 9건으로 가장 발생하였다. 산불발생이 가장 많이 발생하는 시기를 월별로 살펴본 결과 연중 가장 건조한 봄철인 2~4월에 산불 건수와 피해 면적이 가장 많았으며, 특히, 4월에 29건이 발생하였다. 피해면적별 산불 현황은 1ha 내 외로서 피해 규모가 크지 않는 것으로 분석 되었다.

  • 원전입지에 대한 주민반발문제는 경제성장과 더불어 가일층 증가일로에 있는 전력수요에 안정적으로 대처해야만 한다는 측면에서 시급히 극복해야만 할 사회문제이다. 본 연구에서는 바로 이러한 사회문제를 극복하기 위해 원전입지반발과 주민참여와 관계를 이론적으로 고찰하였고, 또한 삼척 원전 반발사례를 분석하였다. 분석결과, 원전반발과 주민참여는 매우 밀접한 관계에 있는 것으로 나타났다. 즉, 미흡한 주민참여는 원전반발에 직접적인 영향을 미치는 것으로 나타났다. 따라서 원전을 성공적으로 입지시키기 위해서는 정부가 일방적으로 원전정책을 결정하고 집행해서는 곤란하며, 원전정책에 반드시 지역주민들의 의사를 적극적으로 반영할 필요가 있다.
