Pollination is an essential process for plants to carry on their generation. Pollination is carried out in various ways depending on the type of plant species. Among them, pollination by insect pollinator accounts for the most common. However, these pollinators have be decreasing in population density due to environmen- tal factors. Therefore, use of artificial pollination is increasing. However, there is a lack of information on microorganisms present in the artificial pollens. We showed the... -

한국식물병리학회 The Plant Pathology Journal 2020, 36권 5호 3 406-417 (12 pages)
Early warning services for crop diseases are valuable when they provide timely forecasts that farmers can utilize to inform their disease management decisions. In South Korea, collaborative disease controls that utilize unmanned aerial vehicles are commonly performed for most rice paddies. However, such controls could benefit from seasonal disease early warnings with a lead time of a few months. As a first step to establish a seasonal disease early warning service using seasonal climate... -

Take-all of Wheat and Natural Disease Suppression: A Review
한국식물병리학회 The Plant Pathology Journal 11 Pages
한국식물병리학회 The Plant Pathology Journal 2013, 29권 2호 2 125-135 (11 pages)
In agro-ecosystems worldwide, some of the most important and devastating diseases are caused by soil-borne necrotrophic fungal pathogens, against which crop plants generally lack genetic resistance. However, plants have evolved approaches to protect themselves against pathogens by stimulating and supporting specific groups of beneficial microorganisms that have the ability to protect either by direct inhibition of the pathogen or by inducing resistance mechanisms in the plant. One of the best... -

Nonpoint source (NPS) pollution continues to degrade the water quality. NPS pollutants signals high concerns against a sustainable environment. Low impact development (LID) is the leading management practice which regulates and treats stormwater runoff especially in highly impervious urban areas. Constructed wetlands are known to have efficient removal capability of NPS pollutants. Likewise, these LID facilities were intended to maintain the predeveloped hydrologic regime through series of... -

In order to assess the role of aeration in stormwater wetlands, oxygen supply and consumption in a wetland treating runoff from livestock farms were estimated and analyzed. Furthermore, oxygen mass balance was conducted during day time and night time. Internal production by algal photosynthesis dominated the oxygen production particularly in the shallow marsh due to the large amount of algae. Consequently, algal respiration was also the major oxygen depletion element with nitrification and... -

본 연구는 도시 강우유출수 처리를 위한 하이브리드 빗물정원 시스템을 개발하고자 수행되었으며, Pilot scale 모니터 링을 통하여 시스템 내의 서로 다른 구성요소간의 효율을 검증하였다. 유입수는 국내·외 도로강우유출수의 농도를 고 려한 인공강우유출수를 이용하여 수행하였다. 모니터링 결과 하이브리드 빗물정원은 시설 내 저류 80%, 지하수의 침 투 15%로 유입수의 약 95% 저감되는 것으로 나타났다. 이는 ST의 저류 및 PB와 IT의 침투 기작이 물순환 효과에 기 여한 것으로 판단된다. 또한 오염물질 저감효율을 산정한 결과,... -

Diverse and comprehensive countermeasures were established to prevent water pollution in coastal areas such as constructed wetlands(CW).This study was conducted to assess the water quality improvement through CW constructed along the shoreline of Hwaseong coastal reservoir. The CW is located in Hwaseong-si, Gyeonggi-do and consisted of a forebay and a wetland. The CW was monitored twice during rainy days and 10 times during dry days. The monitoring results indicated that in and out flowrates... -
겨울철 한강 장항습지에 서식하는 매 멸종확률 예측에 대한 연구
한국습지학회 한국습지학회지 2016, Vol.18 No.3 10 282-285 (4 pages)
매(Falco peregrinus)는 천연기념물 323호이며 멸종위기종으로 등재되어 있다. 본 연구는 한강의 장항습지에 서식하는 매의 멸종확률을 개체군변이분석을 통하여 시도하고자 한다. 장항습지는 개체군이 1999-2005년 동안 모니터링되었으 며 평균 10.8 개체가 서식하는 것으로 조사되었으며, 개체군을 이용하여 향후 5년간(2015-2020) 변이분석을 실시하였 다. 초기개체군을 이용하여 기간 동안 20%의 멸종확률이 예측되었으며, 이 확률은 지역의 수질오염과 서식지 손실을 고려하면 적은 것으로 나타났다. PVA는 개체군이 적고 다른... -

A set of lab-scale polymer synthetic fiber packed column wetlands composing three columns (CW1, CW2 and CW3) with different hydraulic regimes, recirculation frequencies and pollutant loading rates, were operated in 2012. Synthetic fiber tested as an alternative wetland medium for soil mixture or gravel which has been widely used, has very high pore size and volume, so that clogging opportunity can be greatly avoided. The inflow to the wetland was artificial stormwater. All the wetlands achieved... -

도시화는 불투수면의 증가를 초래하여 자연적인 물순환 시스템의 왜곡, 비점오염물질 유출 증가, 하천의 수질악화 및 수생태계 훼손 등의 문제를 발생시킨다. 불투수면 증가로 인한 수리수문학적, 생태학적 및 환경적 영향을 저감하기 위하여 선진국에서는 저영향개발(Low Impact Development, LID)기법을 주요한 대안으로 적용하고 있다. 국내에서도 2012년에 비점오염원관리종합대책을 통하여 LID 기법을 비점오염 관리의 주요 방안으로 추진하고 있다. LID 시설은 물순환 구축을 통한 강우유출수의 유출저감과 함께 식물, 미생물,...
