9$\cdot$10월은 중$\cdot$만생종의 수확기이다. 이제까지의 고된 작업과 병해충과의 씨름도 어느정도 마무리 단계에 접어들게 되나 아직까지도 자칫 방심하면 다지어 놓은 농사를 망치기도 하고 조기낙엽에 의하여 내년도의 개화결실에도 나쁜 영향을 미치게 된다. 따라서 작업의 선후를 잘 계획하여 한 해의 농사를 마무리 지어야한다. 9$\cdot$10월의 중요한 과수원작업은 착색관리, 적기수확 및 저장, 추비시용인데, 병해충이 많을 때에는 약제방제도 소홀히 할 수 없으며, 태풍의 피해가 우려되는 과수원에서는 이에 대한 대비도 하여야 한다.

지난해에 이어 연속적인 풍년을 이룩하여 주곡의 안정적 자급을 유지하려는 것이 국민 모두의 염원이다. 그러나 풍년농사를 이룩한다는 것은 그렇게 쉬운 것은 아니다. 농민은 농민대로 연중 모든 어려움을 참고 꾸준히 노력하여야 하고 관계 유관기관에서는 농사가 잘 지어질 수 있도록 여러 가지 여건을 사전에 조성하여 주어야 한다. 따라서 금년에도 풍년농사를 기필코 달성하기 위하여 분야별로 치밀한 계획을 수립하여 사전준비를 단계적으로 추진중에 있다. 그중에서도 수량에 가장 영향을 많이 미치는 병충해 방제에 대한 금년도 대책을 약술하면 대략 다음과 같다.

우리가 농토배양을 선두로 못자리 설치에서부터 긴 여름불볕 더위속에서 열심히 벼농사를 짓는 것은 결실의 계절인 가을에 질이 좋은 쌀, 보다 많은 쌀을 풍성한 마음으로 거두기 위해서 이다. 특히 올해는 벼 안전 다수확을 위해서 겨울 논물가두기부터 시작하여 못자리 조기설치, 일찍 모내기를 끝내고 적기병충해 방제와 마지막 단계에서 뜻밖의 폭우가 있었지만 폭우의 피해까지도 어느 정도 슬기롭게 극복하여 이제 최후의 거두어 들이는 작업에 온 정성을 다할 때가 되었으며 또 내년을 위해 금년 한해동안의 벼농사에서 잘 되었던 점과 못 되었던 점을 정리해 두었다가 거울로 삼는 것도 바람직하다.

That occur in the ocean and the efficient management of marine litter on marine pollution oil spill response one step further strategies are needed. Marine pollution accidents occurred in 2011, a total of 287 and was found in runoff 369 kL, respectively compared to the previous year decreased by 13% and 39%. Average amount of marine materials during 5-years represent the oil flow of 310.5 kL (heavy fuel oil of 106.0 kL, diesel of 178.9 kL, oily bilge water of 22.3 kL, other oil of 7.7 kL) and the waste of 62.3 tons, the hazardous and noxious substances (HNS) was 510.6 kL. Marine emissions in 2011 by type of waste that a total amount of dumping 3,972 $m^3$, and livestock manure 795 $m^3$(20%), waste water 1,431 $m^3$(36%), sewage sludge 887 $m^3$(22%), wastewater sludge, 813 $m^3$(21%), manure 5 $m^3$(0.1%), other 41 $m^3$(0.9%), respectively. The concept of marine waste and needs to be more clearly defined. Integrated management of hazardous chemicals according to the incident management system should be established. To remove of coastal pollution, response officer needs korean coast response system. Like the marine pollution response, coastal pollution response systems also require step response.

Sunflower, selected as a trap plant that can be controlled by attracting Ricania spp. adults via attraction has the highest attractiveness during the preoviposition period. Considering the ecological characteristics of Ricania spp., adults are distinguished by the preoviposition and oviposition periods and the attractiveness of sunflower to Ricania spp. adults was 91.4~95.2% higher than that of blueberry during the preoviposition period. On August 20, when Ricania spp. adults entered the oviposition season, sunflower attractiveness was low at 9.8~11.6% owing to preference for tree species. Based on the result of the selection of systemic chemicals that could be used concomitantly with sunflower, all chemicals, except etofenprox, showed a high controlling effect of over 90%, and among them, dinotefuran showed the highest insecticidal rate of 95.8%. The systemic chemicals acetamiprid, dinotefuran, thiamethoxam, and imidacloprid persisted for 13 days (survey period). Therefore, the concomitant use of sunflower and systemic chemicals can reduce the density of Ricania spp. entering farmlands and their populations in surrounding habitats, which are expected to help in stabilizing the ecosystem.

This study was conducted to investigate the effect of integrated pest management (IPM) with 3point 5score microscopic monitoring method for laying farms infected with poultry red mites. A total of 8 laying farms infected with poultry red mites were divided into two treatments: 1) integrated pest management with 3point 5score microscopic monitoring method and 2) normal pest management with 3point 5score microscopic monitoring method. The results revealed that there is no significant difference between the groups with respect to the score of poultry red mites not only regardless of disinfection for the laying farms but also from week 4 to week 20 (P>0.05). However, the farm with IPM had a lower (P<0.05) score than those with the normal pest management method on week 24. Based on the result of the present study, controlling the presence of poultry red mites using IPM, along with consistent monitoring and supplementation using the 3point 5score microscopic monitoring method, is deemed effective in reducing the ultimately targeted infection rate of poultry red mites.

When oil is spilled at sea, the oil boom is commonly used to tackle the movement and spreading of oil in an early stage of oil spill combat. But the retaining capability of oil boom is affected by various factors, such as water velocity, viscosity and density of oil, water depth, oil volume and the length of boom draft. In this study, a computer modelling was peformed to investigate how these factors influence the oil retaining process. The Fluent, most popular one of many CFD(computational fluid dynamics) programs is chosen for modelling and modelling results were verified using the empirical data. It is expected that results of this study will be useful data for oil boom designer and oil spill response commander.
