이상엽,신수연,Lee, Sang-Yeob,Shin, Sooyeon 대한턱관절교합학회 2008 구강회복응용과학지 Vol.24 No.4

임플란트의 도입으로 악골이 흡수된 무치악 환자의 보철 치료에 획기적인 변화가 가능해졌다. 특히 하악 무치악 환자의 경우 2개의 임플란트에 의해 유지를 얻는 피개의치가 일반적인 총의치의 대안으로 자리잡았으며 첫 번째로 고려되어야 할 치료 방법으로 받아들여지고 있다. 본 증례는 상하악 완전 무치악 환자로서 상악에는 일반적인 총의치, 하악에는 2개의 임플란트를 식립하고 $Locator^{(R)}$ Attachment를 사용하여 수복한 임상과정 및 결과에 관하여 보고하고자 한다. It is difficult to provide prosthodontic treatment to fully edentulous patients with severe alveolar bone resorption, because this makes patents hard to endure functional load, and to adapt to the dentures, which result in emotional stress to patients. Implant supported overdenture can be chosen to solve these problems. Among several types of them, the implant retained and tissue supported overdenture, is available to the patients of low masticatory force with the reduced cost. Attachments also can be used for increasing retention and esthetics in dentures. Especially, $Locator^{(R)}$ system needs a small vertical interarch space for restoration and is able to compensate the difference of angle between fixtures. In this study, we restored maxilla with conventional complete denture, and mandible with implant and tissue supported overdenture and $Locator^{(R)}$ system.

이상엽,류재당,김홍기,Lee, Sang-Yeob,Ryu, Jae-Dang,Kim, Hong-Gi 한국식물병리학회 2005 식물병연구 Vol.11 No.2

Ampelomyces quisqualis 94013는 중복기생균으로 흰가루병 생물적 방제용 우수균주로 선발하여, 이 균의 효율적 이용을 위한 배양적 특성을 조사하였다. A. quisqualis 94013의 균사생육 적은은 $26^{\circ}C$이였으며, 균사생육 최적 pH는 6.5였다. 감자한천배지(PDA)배양시 광조건(형광등 12시간주기)보다는 암조건에서 더 많은 포자를 형성하였다. 이 균의 포자발아 온도범위는 $10\~35^{\circ}C$이고, 최적온도는 $20^{\circ}C$이였다. 포자발아는 $24^{\circ}C$에서 8시간 배양 후 시작되었으며, 포자발아율은 포자현탁액의 농도가 $5{\times}10^7/ml$보다 $5{\times}10^5/ml$나 $5{\times}10^6/ml$에서 높았다. 이 균은 탄소원으로는 dextrin을, 질소원으로는 neopepton을 가장 잘 이용하였다. Ampelomyces quisqualis 94013 (AQ94013), a hyperparasite, was selected as an effective biological control agent against cucumber powdery mildew. Optimal temperature for mycelial growth of AQ94013 was $26^{\circ}C$, and the optimal pH was 6.5. Conidia of AQ94013 were more Produced on potato dextrose agar (PDA) in darkness than under alternating cycles of 12 hr fluorescent light and 12 hr darkness. Temperature range for spore germination of the fungus was $10\~35^{\circ}C$, and optimal temperature was $20^{\circ}C$. Conidial germination of the fungus began 8 hr after incubation at $24^{\circ}C$. Germination rate of conidia at concentration of $5{\times}10^5\;spores/ml\;and\;5{\times}10^6\;spores/ml$ was higher than at concentration of $5{\times}10^7\;spores/ml$. The best source of carbon and nitrogen for mycelial growth of the fungus were dextrin and neopeptone, respectively.

이상엽(Lee Sang Yeob),주헌식(Joo Heon Sik) 한국컴퓨터정보학회 2008 韓國컴퓨터情報學會論文誌 Vol.13 No.1

소규모 환경에서 크로마키 기법은 UCC 콘텐츠를 제작하는데 매우 필요한 부분이다. 지금까지는 크로마키를 하기 위해 배경에 단일 색을 사용한 막을 사용 하였다. 본 논문은 일반 배경에 객체가 설정 되었을 때 객체를 추출하는 크로마키를 제안한다. 본 논문은 웨이블릿을 이용하여 고주파와 저주파를 분리 하여 노이즈를 제거하는 새로운 방법으로 크로마키를 시도 하였다. 결과로 성능 좋은 크로마키 기법을 개발 하였다. The man who wants to create advance user created contents is in need of using chroma-key method in a certain environment. Recently, pavilion that is painted with mono-color is used for the application of chroma-key. This paper aims to introduce a robust automatic adaptive chroma-key method without using pavilion. In this research, a new chroma-key method is applied to the separation of high frequency and low frequency using Wavelet is done in order that the noise can be eliminated. As a result, a chroma-key method with good capacity is shown from the research.

The prototypes, Rto-x+Ca(NO₃)₂, K-Ca, and Rto-xβ, which were extracted from spent mushroom substrate of Hericium erinaceus, strongly inhibited the growth of Ralstonia solanacearum. The control efficacies of tomato bacterial wilt by treatment with Rto-x+Ca(NO₃)₂, K-Ca, and Rto-xβ were 87.4~92.4%, 46.0~100%, and 65.0~91.9%, respectively. These results indicate that Rto-x+Ca(NO₃)₂, K-Ca, and Rto-xβ have a potential as eco-friendly antibacterial materials for the control of tomato bacterial wilt caused by R. solanacearum.

Streptomyces sp. A75와 A501 균주의 인삼 잘록병에 대한 방제효과

이상엽 ( Sang Yeob Lee ),송재경 ( Jaekyeong Song ),윤봉식 ( Bong-sik Yun ),박경훈 ( Kyeong Hun Park ),김정준 ( Jeong Jun Kim ),한지희 ( Ji Hee Han ) 한국균학회 2016 韓國菌學會誌 Vol.44 No.4

Streptomyces sp. A75 and A501 inhibited the mycelial growth of pathogenic Rhizoctonia solani and Pythium sp., which cause the ginseng disease known as damping-off. Three methods were evaluated for the control of these pathogens, using a mixture of the culture broths from Streptomyces sp. A75 and A501. The methods tested were seed dipping with 50-fold diluted broth, drenching of soil with 100-fold diluted broth after sowing, and combined seed dipping and drenching. These methods reduced the incidence of ginseng damping-off caused by R. solani by 81.3%, 84.8%, and 32.2% and that caused by Pythium sp. by 51.0%, 52.1%, and 75.3%, respectively. Based on these results, the combination of seed dipping and soil drenching after sowing using a mixture of the culture broths from Streptomyces sp. A75 and A501 effectively reduced the incidence of dampingoff in ginseng.

보문 : Bacillus amyloliquefaciens M27에 의한 오이 흰가루병의 생물적 방제

이상엽 ( Sang Yeob Lee ),원항연 ( Hang Yeon Weon ),김정준 ( Jeong Jun Kim ),한지희 ( Ji Hee Han ),김완규 ( Wan Gyu Kim ) 한국균학회 2013 韓國菌學會誌 Vol.41 No.4

Bacillus amyloliquefaciens M27 was isolated from the cotton-waste compost for cultivation of oyster mushroom (Pleurotus ostreatus). B. amyloliquefaciens M27 is a biocontrol agent with antagonistic activities against a wide range of fungal pathogens. The aim of this work was to evaluate the possibility of exploiting antagonistic bacteria, B. amyloliquefaciens M27, in the biological control of the cucumber powdery mildew fungus, Podosphaera fusca. In greenhouse tests, the isolate was found to be very effective to control powdery mildew on cucumber leaves showing 4.0% diseased area, whereas diseased area in the control was 80.5%. The filtrate of the isolate cultured on MH and LB media were more effective for control of the disease than those cultured on TSB, NB, and KB media. When two, five, ten, 20, 50 and 100-fold diluted culture broth of isolate on LB media were treated, disease areas were 0%, 0%, 0%, 1.3%, 3.1% and 5.0%, respectively, whereas diseased area in the control was 60.0%. The filtrate of the isolate cultured on LB media was treated to cucumber plants on July, October and December just before the outbreak of the powdery mildew occurred. When 10-fold diluted filtrate of the isolate was treated, control efficacy was 88.9~98.9% in the treated seasons. The results showed that the culture filtrate of B. amyloliquefaciens M27 was very effective to control powdery mildew of cucumber.
