初生雛 育成飼料의 主飼料인 옥수수의 代置飼料로서 밀을 이용한 代置水準을 究明하고저 本 實驗을 實施하였던 바 그 結果는 다음과 같다. 1. 增體量은 옥수수와 밀을 各各 50%씩 使用한 區와 밀보다 옥수수를 많이 使用한 區가 밀 만을 使用한 區에 비해서 增體量이 좋았다. 2. 飼料攝取量은 옥수수를 제일많이 使用한 區가 제일 적었고, 반대로 밀을 많이 사용한 區 일수록 높았다. 3. 飼料效率은 옥수수와 밀을 50%씩 使用한 區가 옥수수와 밀의 單用區 보다는 좋았다. 4. kg增體에 所要된 飼料費는 옥수수와 밀을 50%씩 사용한 區가 제일 낮아 本 試驗에 의하면 養鷄配合飼料의 穀類 60%中 밀을 30%程度 使用할 수 있다고 하겠다. To investigate the substitute level of wheat for corn used as major ration of laying hen, was carried out. The results obtained were as follows: 1. Body weight gain was higher in the treatment of Corn 50% : Wheat 50% and in used more corn than wheat in contrast with the treatment used only wheat. 2. Diet intake was least in the treatment used only corn and on the other hand, the only wheat was higher than other treatment used corn in the diet intake. 3. Feed efficiency was more improved in the treatment used 50% of wheat and corn, respectively than in the treatment used only wheat. 4. Feed cost required per kg body gain was lowest in the treatment used 50% of wheat and corn. Therefore, according to the present experiment it may be to say that s0% of wheat will be substituted for corn in the formulated ration of laying hen using 60% cereals.

마늘 잎마름 症狀의 藥劑防除 效果

吳正行 단국대학교 1994 論文集 Vol.28 No.-

To obtain a basic information necessary for controlling leaf blight caused by complex infection with Stemphyllium botryosum and Alternaria porri in gralic, fungicides, Capro WP, Ipro WP and Metasyldong WP were examined for the inhibition activity of growth and control value to the pathogens. The result obtained were summarized as follows. 1. Leaf blight of gralic caused by the complex infection with S. botryosum and A. porri occured at the beginning of May and drastically increased at the beginning of July when the aged plants were subjected to high temperature and mositure short of fertilizer. 2. Mycelial growth of S. botryosum and A. porri was more inhibited by Capro WP and Ipro WP than Metasyldong WP and it was marked even at the concentration of 1㎍/ml which is used for field spary in general. S. botryosum was more inhibited than A. porri. 3. Sporulation of S. botryosum and A. porri was markedly reduced by the fungicides, even at the concentration of 1㎍/ml. There was not significant in difference between the fungicides but the reduction was greater in S. botryosum than A. porri. 4. Control value of the fungicides was 75.0% in Metasyldong WP, 80.1% in Capro Wp and 80.6% in Ipro WP. The value increased positively in proportion to inhibition of mycelial growth and spore formation. 5. It could be concluded that the fungicides tested might be not sufficient for controlling leaf blight of gralic caused by complex infection with S. botryosum and A. porri, because A. porri was less sensitive to the fungicides.

송하정,박수정,황윤찬,오원만,황인남 大韓齒科保存學會 2008 Restorative Dentistry & Endodontics Vol.33 No.4

본 연구는 레진 시멘트의 색 안정성을 평가하여, 레진 시멘트의 변색에 의한 심미 수복물의 실패의 가능성을 평가하고자 시행하였다. 4종의 이원중합형 레진 시멘트인 Panavia-F (PA; KURARAY), Duolink (DL; BISCO), Variolink II (VL; Ivoclar Vivadent),및 RelyX Unicem (UC; 3M ESPE)과 1종의 자가중합형 레진 시멘트인 Resiment Ready-Mix (with fluoride) CE (RM: j.l.Blosser)를 사용하였으며 , 대조군으로 복합레진 Gradia Direct (GD; GC)과 복합 레진 인레이용 Tecera Dentin A3 (TE; Bisco)를 사용했다. 각 재료 당 직경 6.5 ㎜, 두께 4.5 ㎜의 디스크형 시편 10개를 제작하였다. 중합 후 시편은 분광색채계측기인 Spectrolino (GretagMacbeth)를 이용해 CIE L^(*)a^(*)b^(*)값을 측정하고 가속시험을 위해 빛이 차단된 refrigerated bath circulator에서 60 ℃ 증류수에 30일간 보관 후에 색 측정을 시행하고, 시험 전 후의 색차를 계산하였다. 가속 시험 후 L^(*) 값은 감소하는 앙상을 보였고, a^(*) 값은 증가하는 양상을 보였지만 유의한 차이는 없었다. 반면 b^(*) 값은 유의하게 증가하였다 (p<0.05). TE가 15일과 30일 모두에서 가장 적은 색변화 (p < 0.05)를 보인 반면 GD는 15일 가속 실험 후 큰 색변화를 보였다. 30일 가속 실험 후 PA, VL, RM, DL 그리고 UC 순으로 ΔE^(*)값이 커졌으며 (p < 0.05), 30일 후 모든 레진시멘트들은 육안으로 변색을 인지할 수 있는 3 이상의 ΔE^(*) 값을 보였다. The purpose of this study was to evaluate the color stability of resin cements with accelerated test. Four dual curing resin cements: Panavia-F (KURARAY), Duolink (BISCO), Variolink-II (Ivoclar Vivadent), and RelyX Unicem (3M ESPE) and 1 self curing resin cement: Resiment CE (j. 1. Blosser) were used in this study. In control group, Gradia Anterior (GC) composite resin and Tescera Dentin (Bisco) indirect composite were used. Ten disk shape specimens were made from each resin cement. The specimens were subjected to an accelerated aging process in a refrigerated bath circulator at 60 ℃ for 15 and 30 days. Spectrophotometric analyses were made before and after 15 days and 30 days of accelerated aging time. The color characteristics (L^(*), a^(*), b^(*)) and the color difference (ΔE^(*)) of the specimens before and after immersion were measured and computed. Regardless of type of the resin cements, L^(*) value was decreased and a^(*) value was increased, but there were no significant difference. But b^(*) value was increased significantly (p < 0.05). Tescera inlay showed least color change (p < 0.05), but Gradia showed notable color change after 15 days. After 30 days on accelerated aging, ΔE^(*) value was increased (Panavia-F < Variolink-II < Resiment CE < Duolink < Unicem) (p < 0.05), but there were no significant difference among Panavia-F, Variolink-II, and Resiment CE groups. After 30 days of accelerated aging, ΔE^(*) value of all resin cements were greater than 3.0 and could be perceived by the human eye.

Efficacy of Fluazinam and Iprodione+Propineb in the Suppression of Diaporthe phaseolorum, Colletotrichum truncatum and Cercospora kikuchii, the Causal Agents of Seed Decay in Soybean

Oh, Jeung-Haing,Kang, Nag-Won The Korean Society of Plant Pathology 2002 Plant Pathology Journal Vol.18 No.4

Seed decay of soybean caused by Diaporthe phaseolorum, Colletotrichum truncatum and Cercospora kikuchii is a serious disease when soybean is harvested under warm and wet weather conditions. Benomyl has been used for controlling the disease, however, benomyl application may be limited due to common occurrence of resistance. The efficacy of 21 fungicides against the pathogens was evaluated in vitro. Among the fungicides tested, benomyl, carbendazim, fluazinam, iprodione+propineb, thiophanate-methyl, and triflumizole were found effective and were evaluated for their ability to control the seed pathogens. Fluazinam completely inhibited mycelial growth at a concentration of 100 $\mu\textrm{g}$/$\textrm{m}{\ell}$ for D. phaseolorum; and at a concentration of 500 $\mu\textrm{g}$/$\textrm{m}{\ell}$ for C. truncatum and C. kikuchii. $EC_90$ values of fluazinam were similar to that of benomyl. Because fluazinam, iprodione+propineb, and triflumizole were found effective against the seed pathogens, these were subjected for field-testing. Suppression of pod and seed infection by fluazinam and iprodione+propineb was as high as that of benomyl without any reduction in agronomic characters of soybean. This study shows that fluazinam and iprodione+propineb may be used in combination with benomyl to control seed pathogens, manage resistance, and ensure production of high quality soybean seeds.

Jeung Haing Oh,Hoo Sup Chung 한국응용곤충학회 1984 한국응용곤충학회지 Vol.23 No.1

대두갈색무늬병균의 포자발아(分生胞子發芽) 미치는 외부영양공급(外部營養供給) 및 self-inhibitor의 영향(影響)을 조사하여 다음과 같은 결과(結果)를 얻었다. 1. 갈색무늬병균의 포자발아율은 감자한천배지 및 대두잎조각을 첨가한 증류수에서는 양호하였으나 살균된 증류수에서는 극히 불량하였다. 2. 갈색무늬병균의 포자발아에는 탄소원의 외부공급이 절대 필요한 것으로 보였으며 인산, 가리 등은 큰 영향이 없는 것으로 보였다. 3. 탄소원으로서는 가용성 전분이 가장 효과적이었고 다음이 포도당, 유당 등이었으며 포도당의 경우 농도에서 가장 높은 발아율을 보였다. 4. 포자발아율은 포자밀도가 높을수록 현저히 감소하여 포자농도 이상에서는 거의 발아하지 않는 것으로 보아 self-inhibitor가 존재하는 것으로 보였다. 5. 기질(基質)을 세척한 포자의 발아율은 세척하지 않은 포자의 발아율에 비해 낮았으며 이러한 현상은 포자농도가 이상으로 증가할 때 더욱 현저하였고 건조된 한천배양기위에는 발아율 감소가 현저하였다. Conidial germination of Septoria glycines Hemmi, brown spot fungus of soybean, was studied by slide germination test. Poor conidial germination of S. glycines was observed on sterile distilled water, but potato dextrose agar(PDA) and distilled water floated with soybean leaf disc furnished a satisfactory medium for conidial germination. Exogenous supply of carbon source was essential for conidial germination, while phosphorous and potassium were not evident as that for carbon. Soluble starch was the most suitable as a carbon source for conidial germination and followed by D-glucose, D-galactose and lactose in that order. Maximum germination was attained in the . concentration of glucose. Germination was decreased with increment of conidial concentration and was almost completely suppressed in the density of 10,000 conidia per . It suggested existing a self-inhibitor(s). Non-washed conidia germinated more than washed conidia and this was obvious when the conidia density was over conidia per on the dry agar block.

JEUNG HAING OH 한국응용곤충학회 1985 한국응용곤충학회지 Vol.24 No.2

The present study was carried out to determine appropriate growth stage for evaluating resistance to septoria brown spot in field and to search resistance sources from soybean germ plasm. Disease severity expressed by log was different with soybean genotypes and vertical progress of the disease was related to the diseased leaf area. Correlation between diseased leaf area and the area under septoria brown spot disease progress curve (AUBC) was highest at full blooming stage, indicating a reasonable stage for measuring the disease severity to evaluate resistance in field. There was no lines highly resistant to the disease among 1,428 native soybean lines tested. 대두(大豆) 갈색무늬병에 대한 저항성(抵抗性)의 포장검정(圃場檢定)에 적합한 생육시기(生育時期)를 결정하고 수집재래종(蒐集在來種)으로부터 저항성인자원(抵抗性因子源)을 찾기 위 하여 본실험(本實驗)을 수행하였던 바, 1. 갈색무늬병에 대한 저항성(抵抗性) 품종간(品種間)에 차이(差異)가 현저하였으며 수직감염율(垂直感染率)과 병반면적율간(病斑面積率間)에는 상관(相關)이 있었다. 2. 병반면적율(病斑面積率)과 병진전곡선면적(病進展曲線面積)과의 상관도(相關度)는 대두(大豆) 생육기중(生育期中) 개화기(開花期)에서 가장 높아 포장에서의 저항성 검정시기는 개화기(開花期)가 적당한 것으로 보였다. 3. 수집재래종(蒐集在來種) 1,428계통의 저항성(抵抗性) 검정결과(檢定結果) 고도저항성(高度抵抗性) 계통(系統)은 발견할 수 없었고 중도저항성(中度抵抗性)인 4 계통(系統)을 선발할 수 있었다.

The Relation of Soybean Seedcoat Mottling with Podding Location and Seed Transmissibility in Soybean Mosaic Virus

Oh, Jeung-Haing The Korean Society of Crop Science 1984 Korean journal of crop science Vol.29 No.3

Association of SMV infection in soybean plants with seedcoat mottling and with seed transmission of SMV was examined. Seedcoat mottling was increased positively in proportion to the SMV severity in variety Clark. No correlation was found between the incidence of mottled seed and the seed's position on the plant. Susceptible variety with virus symptoms gave rise to mottled seeds but only a small percentage of these mottled seeds could transmit the virus. SMV could be transmitted even by nonmottled seeds harvested from SMV infected plants in similar rate with mottled seed. It seemed that the amount of mottled seed could be used as an indicator of the amounts of SMV infection in a seed production field. 콩모자이크 바이러스(SMV)에 의한 갈반립의 형성율과 SMV의 종자전염율을 조사하기 위하여 대두품종 Clark, Woodworth, 북해1호를 재료로 SMV 이병정도와 갈반립율 결협절위 및 갈반립형성등의 관계를 조사하고 그 갈반립을 통한 SMV의 종자전염율을 면역이중확산법과 유묘감염률로 조사하였다. 1. 갈반립의 형성율은 식물체의 이병정도와 정비례적인 상관(r=0.796)을 보였다. 2. 이병식물체의 갈반립형성은 결협절립 및 협중종실위치와 유의상관이 없었으며 (r=0.34), 동일절위 및 협내에서도 갈반립과 비갈반립이 함께 형성되었다. 3. 면역이중확산법으로 조사한 SMV의 종자전염율은 4.2 -33.3%로 비교적 낮았으며 품종에 따라 현저한 차이가 있었다. 4. 유묘에 나타난 SMV 증상으로 조사한 종자전염율은 면역이중확산법으로 검정한 종자감염율보다 약관 높게 나타났으며 이는 항혈청의 역가 또는 Virus의 체내증식과 관계가 있는 것으로 보였다. 5. 이병직물의 갈반립은 SMV 종자전염율과 일치하지는 않으나 SMV의 포장이병율 추정에 유용한 지표가 될 수 있으며 파종시 갈반립의 제거는 SMV 전염원의 감소효과를 가져올 수 있을 것으로 보였다.

( Jeung Woo Kim ),( Myeung Su Lee ),( Chang Hoon Lee ),( Ha Young Kim ),( Soo Uk Chae ),( Han Bok Kwak ),( Jae Min Oh ) 생화학분자생물학회 (구 한국생화학분자생물학회) 2012 BMB Reports Vol.45 No.5

Osteoclasts are multinucleated cells that are formed by the fusion of pre-fusion osteoclasts (pOCs). The fusion of pOCs is known to be important for osteoclastic bone resorption. Here, we examined the effect of IFN-γ on the fusion of pOCs. IFN-γ greatly increased the fusion of pOCs in a dose-dependent manner. Furthermore, IFN-γ induced pOC fusion even in hydroxyapatite- coated plates used as a substitute for bone. The resorption area of pOCs stimulated with IFN-γ was significantly higher than that of the control cells. IFN-γ induced the expression of dendritic cell-specific transmembrane protein (DC-STAMP), which is responsible for the fusion of pOCs. IFN-γ enhanced DC-STAMP expression in a dose-dependent manner. The mRNA expression of c-Fos and nuclear factor of activated T cells (NFAT) c1 was enhanced in the pOCs treated with IFN-γ. Taken together, these results provide a new insight into the novel role of IFN-γ on the fusion of pOCs. [BMB reports 2012; 45(5): 281-286]
