  • This study was conducted from April 1 to September 31, 1973. Ten strains of Fusarium spp. were isolated from the diseased ginseng in two local areas at Kangwha-Gun nad Kumsan-Gun in Korea. Among of them, 2 strains ($G_1$, $G_4$) did not have virulence to ginseng in reinoculation. Their cultural, morphological characteristic and hose virulence to pea seedling were examined. Taxonomical identification of 8 isolates followed by the method of Wollenweber, Snyder nad Toussoun, Booth, Matuo and Snyder. All of eight strains were identified as the Fusarium solani f.sp.pisi(Jones) Synd. et Hans.

  • 위기관리의 목적은 각종 재해 ${\cdot}$ 재난으로 인한 비상사태 발생시 기업의 업무를 지속하고, 신속하게 피해 업무를 복구하는데 있다. 이러한 위기관리의 목적 자체는 언제 어디서나 변함이 없지만, 그 구성 내용과 운영 방안은 시대와 장소에 따라 업무 환경에 알맞도록 적절하게 구성되어야 한다. 따라서 본 논문에서는 한국 기업 환경에 적합한 Business Continuity를 위한 위기관리시스템 개발 모델을 DR. PEAS(Disaster Recovery Plan & Execution Automation System)의 사례를 통하여 제시하고자 한다.

  • The behaviour of interfacial charge in EPDM/XLPE laminates has been investigated by measuring charge distributions using a pulsed electroacoustic (PEA) method. Homocharge develops in EPDM while heterocharge develops in XLPE. A broadly interfacial charge peak is observed at EPDM/XLPE interface. When EPDM /XLPE laminates are treated in high temperature for different times, the amount and polarity of interfacial charge are changed.

  • Chilling-sensitive plants are damaged severly by chilling in the light. The activity of photosystem I(PSI) is known to be inhibited by low light-chilling and its iron-sulfur centers are presumed to be its primary target. In this report, the effect of chilling at 4$^{\circ}C$ in the light was investigated in the level of pigment-protein complexes in cucumber leaves compared with pea leaves. (omitted)

  • Understanding how ionizing radiation propagates from molecular clouds to the intergalactic space is the key to the study of reionization and the emergence of $Ly{\alpha}$ emission from galaxies. In this contribution, I will present our new efforts to better understand the escape of UV photons from turbulent clouds with different masses, star formation efficiencies, and spectral energy distributions using radiation-hydrodynamic simulations. I will also show predicted Lya profiles from turbulent clouds and discuss a few interesting differences identified when compared with the properties of the local green pea galaxies.

  • In March of 2003, the gray mold occurred severely on pea (Pisum sativum) grown in the green houses and open fields in Changseon-myon, Namhae-gun, Gyeongnam Province, Korea. The symptoms started with water-soaking lesions in the leaves, stems and pods. The typical symptoms of the leaves, stems and pods became withered, discolored and blighted, and then eventually died. The mycelia, conidia and conidiophore of the pathogen appeared on leaves, stems and pods. The conidia were gray, 1-celled, mostly ellipsoid or ovoid in the shape and were $8{\sim}17{\times}5{\sim}13\;{\mu}m$ in size. Conidiophores were $14{\sim}30\;{\mu}m$ in size. The sclerotia were formed abundantly on potato dextrose agar. The optimum temperature for sclerotial formation was $20^{\circ}C$. Pathogenicity of the causal organism was proven according to Koch's postulate. The causal organism was identified as Botrytis cinerea based on mycological characteristics. This is the first report on gray mold of Pisum sativum caused by B. cinerea in Korea.
