  • 건고추는 대부분 세척이나 살균의 과정을 거치지 않고 저장, 유통되므로 해충이나 미생물 오염에 의한 식품위생면이나 상품가치면에서 문제가 되고 있다. 고춧가루의 미생물과 해충 방제를 위하여 ethylene oxide나 propylene oxide 등의 훈증제가 사용되고 있으나 문제점이 많아 점차 사용이 금지되고 있는 실정에 있다. ${\gamma}$-선 조사는 훈증제, 자외선 조사, 초단파 처리등 기존의 방법에 비해 살균 효과는 물론 식품의 품질과 건전성 실험 결과에서도 우수하다고 보고되었다. (중략)

  • 국내 농약의 소비는 최근들어 해마다 증가양상을 보여 농업에서 농약의 일반화는 농약의 중독 및 식품의 오염, 자연생태의 파괴등 자연환경에 미치는 영향에 관해 많은 우려의 대상이 되어가고 있다. 그동안 농약사용에서 야기되는 각종 사고를 방지하기 위하여 행정$cdot$지도계통에서 많은 노력을 해왔으나 아직까지 농약을 소홀히 다루는 경향이 많아 농촌진흥청 시험결과를 소개한다.

  • In this paper, pollen types of plants and Pb, N, P, K, Ca and Na in pallens of trees were investigated to control the air and soil pollutions. Morphological types of about 500 species of plants were identified to make the best use of paleontology, medicine and pharmacy. There were the positive correlations between Pb, N, P, K,Ca and Na contents in pollens and soils, respectively. A heavy metal, Pb, contained in pollens was not absorbed by rats. This fact should be utilized to purify air and soils polluted by Pb. Key words: Pb, Pollen, Pollution, puripication, Control.

  • 적조에 대한 대책으로서 가장 많이 이용되는 황토법은 적조생물을 침전시키므로써 제거하지만, 황토의 침전에 의한 2차적인 오염의 가능성이 있다 (Na et al., 1996). 황산구리, 과산화수소와 Triosyn에 의한 적조 살조효과가 있지만 이러한 화학물질은 모든 생물에 대한 살조효과가 있으므로 현상에 사용하기는 힘들다. 생물학적 방제에는 바이러스, 박테리아의 방법이 강구되고 있지만, 산소고갈 등의 2차적인 부작용이 야기된다. (중략)

  • World-wide crop loss caused by insect pest and nematode reaches critical level. In Korea, similar crop loss has been gradually augmented in the field and greenhouse due to continuous crop rotation. The current methods on controlling herbivorous insects and plant parasitic nematodes are mostly depended on agro-chemicals that have resulted additional side-effect including occurrence of resistant insects and nematodes, environmental contamination, and accumulation in human body. To overcome the pitfalls, microbe-based control method have been introduced and applied for several decades. Here, we revised biological control using by the bacteria, fungi, and virus in order to kill insect and nematode and to attenuate its virulence mechanism. The introduced microbes mainly secreted out the hydrolysing enzymes and toxic compounds to target host membrane or cell wall directly. Indirectly, the microbe-triggered plant innate immunity against insects and nematodes was also reported. In conclusion, we provide a new frontier of microbe-based environmentally friendly procedure and effective methods to manage insects and nematodes.

  • Red pepper is seriously damaged by thrips (Thrips palmi) and anthracnose caused by Colletotrichum acutatum throughout its development. Because of biotic constraints, producers often depend on chemicals that are expensive and have adverse effects on the environment, operator, and beneficial insects. In addition, resistance is developed because of the repeated use of chemicals. In recent decades, the use of microorganisms in crop protection has become a credible alternative because it is eco-friendly. In this study, we aimed to select isolates with insecticidal and fungicidal activities against the pathogens that cause anthracnose and thrips. We treated T. palmi adults and juveniles with 13 strains of entomopathogenic fungi (isolated from the soil by using the insect-bait method), and 6 strains showed excellent insecticidal activity (70-100%) 5 days after the treatment. The selected isolates were cultured with C. acutatum to screen for the strain with excellent anti-fungal activities, among which an isolate FT333 showed more than 95% control efficacy against C. acutatum in vitro. The isolate was identified as Isaria javanica through its morphological characteristics and phylogenetic analysis of the ITS and ${\beta}-tubulin$ nucleotide sequences. The Isaria javanica FT333 isolate could be used effectively for dual bio-control of thrips and anthracnose during red pepper cultivation.

  • The experiments attempted to basic studies on the atmospheric dioxide in Korea and on the elimination of sulfur in oil Thiobacilli in order to control of atmospheric sulfur dioxide. The results of experiments are following as : 1) Content of atmospheric sulfur dioxide in industrial zone which used kerosene for fuel was 0.092 ppm(average) and 0.16ppm(maximum). 2) Content of sulfur dioxide at room air which used briquet for stove fire was 0.44ppm (average) adn 0.50 pp,(maximum). 3) Thirteen strains of thiobacilli were isolated from Korean soil and sewage and they were identified with T. thiooxidans (5strains), T. thioparus(3strains), T.ferrooxidans 3 man's observation and the description in Bergey's manual. 4) Two promising strains, one of T. thiooxidans and one of T. ferooxidans. were selected for elimieation of in kerosene.

  • This study was aimed to make GIS oiling thematic maps and analyze temporal oiling variation patterns for two months after 'Hebei Spirit' oil spill accident in December 7, 2007 using GIS and oiling status surveyed data. As a basic work for making of oiling thematic maps, geometric corrections were performed with IKONOS images using ground control points data. These corrected images were used to make detailed coastline from digital charts, and then spatial unit of coastline were defined using classified coastline types. And to know the representative parameters which reflect oiling situation, relationship between oiling status parameters extracted from four times oiling assessment reports and total petroleum hydrocarbons (TPHs) data (December 2007 and January 2008) monitored by Korea Ocean Research and Development Institute (KORDI). Using these representative oiling status parameters pollution value were calculated, and they were keyed into spatial unit of coastline as attributive value. GIS oiling status thematic maps made with coastline containing pollution value showed the initial two month's situations somewhat well. Also, to analyze temporal variation pattern of coastline types, about 13.4km length coastline around Malripo beach was defined as detailed study area where is the common spatial zone surveyed oiling status by each organizations. Based on this study results, it could be possible to provide oiling status maps quickly and to support decision making for oiling control action and scientific pollution monitoring.
