논산딸기시험장에서 시설하우스 내에서 시험 중인 시설딸기에 대하여 프로폴 리스를 농도별로 처리하여 경도, 당도, 산도 및 잿빛곰팡이의 이병과율을 비교하였 다. 경도는 Propolis처리 1일 후 1,000배 처리시 무처리대비 증가하였으나 7일후에 는 유의성이 없었고, 고온기 처리시 250배와 500배처리에서 무처리 대비 7일정도 경도 증가하였다. 당도는 Propolis처리 1일 후 무처리대비 감소하는 경향을 보였으 나 7일 후에는 증가하였고, 고온기 처리시 무처리와 큰 차이는 없었다. 산도는 Propolis처리 1일후에는 무처리와 유의성이 없었으나 500배처리는 7일후 감소하 는 경향을 보였다. 과실의 착색은 Propolis처리시 무처리 대비 L은 같았으나 a(적 색)와 b(황색)는 감소하는 경향이었고 처리간 유의성은 없었다.
Catch of garden thrips, Frankliniella intonsa, on sticky traps was assessed by color and height in commercial plastic vinyl house strawberry crops grown on 40-㎝-high trellises. Yellow, blue and white sticky cards were tested for color attractiveness, and upper (50 ㎝), lower (10 ㎝ above the floor) and ground were for height. At each height, trapped thrips on yellow, blue and white were significantly different. Blue sticky cards were significantly greater than traps on yellow and white. The trapped thrips were also significantly greatest at 50 ㎝ above the floor, less at lower and ground. However, there is no significantly different the population of garden thrips on the flower in each tested site.
The Bridge Safety Department of Seoul Metropolitan Government has regularly conducted precise inspection and precision safety inspection to maintain the bridge's function and safety. During a precise safety inspection in 2015, oil leakage progression was found on the cable anchorage system within the stiffened girder of Nilsen Arch bridge and as a follow-up measure, the cable replacement for the cable ACD11 was carried out in order to identify the relevant cause of the oil leakage and evaluate the integrity of the existing cable. The mechanical properties and fatigue performance tests of the cable strands of bridge inservice for about 20 years and comprehensive analysis of oil leakage were carried out. They were described hereby.
