  • 녹색꽃양배추는 이용부위를 기준으로 할 때 화채류로 분류되어 화전을 수확대상으로 하며 화뢰의 발육적온은 15-18℃로, 재배시기가 고온에 가까워지는 초여름부터 초가을 수확의 작형에서는 화뢰형성 불량 등 이상화뢰의 발생이 많아지게 된다(Fujime와 Hirose, 1981). 특히 봄철 노지 재배에서는 15-25℃의 생육적온을 벗어나는 저온과 고온에 조우될 위험성이 크며, 생육초기의 저온과 후기의 고온이 품질저하의 원인이 되므로 (Takuya와 Tugio 1994), 무리한 조기정식을 피하고 가능한 6월 중순 이전에 수확을 마쳐야 한다.

  • This study analyzes the , one of the three panels of 《Welcoming Banquets for the Governor of Pyeong-an》, a documentary painting of the late Joseon Dynasty, with the aim to identify the coloring materials used in the painting. The painting was first imaged at each wavelength in order to minimize the potential problems in the process of analyzing specific parts. This study applied X-rays to identify ink, gold, and organic and inorganic pigments and used infrared rays to find ink and copper-based pigments. It also applied hyperspectral imaging to distinguish organic pigments from black, blue, and green materials. It also analyzed spots selected for each color to identify the following materials: white lead (white), ink/indigo (black), a combination of red lead and cinnabar (red), pink dye, purple dye, iron oxides (brown), orpiment/dye (yellow), malachite/malachite and yellow dye/indigo (green), azurite/white lead and indigo/indigo (blue), indigo and cochineal (violet), and gold leaf (gold). It is expected that more efficient analysis will be made possible by securing a sufficient library for each wavelength.

  • Bonneh, Cooperman and Sagi (2001) reported that when a global moving pattern was superimposed on high-contrast stationary stimuli, the latter disappeared and reappeared alternatively for periods of several seconds. They named this as motion-induced-blindness. In present research a rotating transparent cylinder composed of white dots was superimposed on a stationary green dots. When observers watched these stimuli wearing a red filter on his/her right eye, the stationary green dots disappeared or reappeared as did in Bonneh et al. The new MIB was observed only when the cylinder rotated and observers weared a red filter. As the luminance contrast of the green dots and that of white dots against the background reduced, and as the number of green dots and white dots decreased, the duration of MIB reduced. Also, the relative depth of the rotating cylinder and the stationary green dots affected the duration of MIB. These results imply that the new MIB is different from the MIB which was observed by Bonneh et al and that the new MIB cannot be explained by binocular rivalry. Further more, the results imply that the later stage of visual information processing is involved in the new MIB.

  • Green mold disease caused by Trichoderma species has recently caused considerable damage to oyster mushroom industries in Korea. This disease Trichoderma, Penicillium, Aspergillus, such as in (genus) to be included in a disease caused by a species that collectively the largest incidence and damage is caused by the pathogen Trichoderma genus. T. longibrachiatum, Trichoderma koningii, Trichoderma virens, T. hazianum, T. atroviride, and T. pseudokoningii were detected on oyster mushroom beds and, of them, T. virens, T. hazianum, T. longibrachiatum was the most frequently detected. The knowledge concerning physiological and ecological properties of Trichoderma spp. was essential for their effective control. T. longibrachiatum hyphal growth is very fast, spore formation, and, particularly well-chlamydospore formation characteristics, and reviews are dark green discoloration. T. koningii, fast mycelial growth, aerial hyphae and spores in aerial hyphae formation is concentrated. T. virens, especially if the color change caused by spore-forming, slow, late in infection, the more severe the damage is discovered. T. hazianum fast mycelial growth, white aerial hyphae and late turns dark green. After spore formation hyphae glob of white pustules or tufts on the top of the formation. T. atroviride. aerial hyphae usually the mycelial growth and spore formation in the unlikely event of the formation and smells similar to the smell of coconut is that. Fast T. pseudokoningii mycelial growth, spore formation is formed around the inoculation site, discoloration of the medium color and well formed chlamydospores.

  • The green pigments of shamanic paintings (83 items) in the 19~20th century were analyzed with X-ray fluorescent spectrometer(XRF), scanning electron microscopy (SEM) and fourier transform infrared spectroscopy (ATR-FTIR). In 60 items, copper and arsenic were detected in green pigments of the paintings by XRF spectra. Cu $K{\alpha}$/As $K{\beta}$ (peak intensity ratio of copper and arsenic) of shamanic paintings of Bokgaedang (shrine), solemn paintings (romance of three kingdoms) of Donggwanwangmyo and unknown enshrined place were 5.93~12.04 and higher compared to 5.67-6.26 of standard emerald greens and 4.01~7.89 of remaining shamanic paintings. The SEM images of crystal forms of copper-arsenic green pigments were various. Crystal forms were divided into oval and round spherulite with intersecting plate crystals and spherulite with agglomerate plate crystals. The crystals of the latter were found in shamanic paintings of Bokgaedang (shrine), solemn paintings (romance of three kingdoms) of Donggwanwangmyo and unknown enshrined place and the former were found in the rest of shamanic paintings. Copper-arsenic green pigments of shamanic paintings were identified as Scheele's green from shamanic paintings of Bokgaedang (shrine) and romance of three kingdoms. Emerald green from the rest of shamanic paintings by ATR-FTIR. From analytical results, it is confirmed that Scheele's green of shamanic paintings of Bokgaedang and romance of three kingdoms was used in the 1850s~1870s and emerald green had been widely used from late 19th century to 1970 in the rest of shamanic paintings.

  • 터키는 알파인 조산대 내의 테티얀 광상대(Tethyan belt)에 위치한다. 이 광상대는 섭입과, 충돌, 열개 운동으로 형성되었고 후기 백악기에서 신생대 화성암류와 오피올라이트(ophiolite)와 관련된다. 터키 지표의 5.5%를 덮고 있는 변성지괴는 북동부의 스트란야(Strandja), 카쟉(Kazdag), 서부의 멘데레스(Menderes), 중부의 키르세히르(Kirsehir), 남동부의 비틀리스(Bitlis)와 포투르지(Poturge)에 분포한다(그림 3과 4). 비교적 연구가 많이 진행된 서부지역의 변성지괴 연구결과에 따르면 변성작용연대는 선캠브리아기에서 올리고세이다. 변성상은 녹색편암상과 각섬암상에서 에콜로자이트상과 백립암상에 이른다(Yigit, 2009). 상기 여러 지괴는 여러 번에 걸쳐 변성작용을 겪었다. 서부의 멘데레스 지괴는 다섯 개의 변성상을 보여주고 있으며, 두 번째 변성작용까지는 알파인 조산운동 이전의 시기이다. 다양한 지질과 지체구조는 터키의 다양한 광상의 부존 가능성을 가능케 한다. 주요자원인 금-동-몰리브덴 광상은 주로 후기 백악기에서 신생대의 화산호와 관련된 반암동과 천열수 광상이다. 동-연-아연 광상은 VMS 중 쿠로코와 사이프러스형 광상과 MVT 광상에 속한다. 알려진 크롬광상의 대부분은 포디폼광상이며 알파인-오피올라이트 암석과 관련된다.

  • Precambrian Jirisan gneiss complex suffered retrograde metamorphism ranging from granulite facies to the amphibolite facies and/or greenschist facies. Intrusive anorthositic rocks in gneiss complex are influenced by late metamorphism. Mafic mineral in anorthositic rock composed mainly of amphiboles, which can anticipate the information about metamorphic conditions and metamorphic facies. Amphiboles from anorthositic rock show subhedral to anhedral in shape and mostly blueish green and/or green in colour in plane polarized light. Some of brownish amphiboles show zonal texture with brownish to blueish green in color from core to rim. Reaction parts in clinopyroxene which exchange with amphibole. It suggests retrograde metamorphism and/or alteration. Amphiboles composing anorthositic rocks can be classified into two types depending on the size and occurrence of amphibole. The first type is microcrystalline amphibole occurring matrix [Group I: ferrohornblende]. The second type is amphibole with 1 mm or larger in size, which is usually occurred in the boundary between opaque mineral and plagioclase [Group II: ferropargasite]. Electron microscopic analyses base on the $Al^{vi}$ composition in amphiboles suggest that the metamorphic pressure of anorthositic rock was low with 5 kbar or less. Ti compositional range in amphibole and representing hornblende+ plagioclase+garnet+biotite+chlorite mineral assemblage suggest that metamorphic facies of anorthositic rock is in amphibolite facies.
