Cyclosulfamuron이 벼의 생육과 Acetolactate Synthase 활성에 미치는 영향

지승환,송성도,정병룡 한국환경농학회 2003 한국환경농학회지 Vol.22 No.1

토양혼화실험을 동한 초장의 신장 억제틀 조사한 결과 초장이 50% 억제되었을 때의 cyclosulfamuron의 농도를 품종별로 비교하여 보면 동진벼, 화성벼, 일품벼의 경우 각각 6.3, 9.2, 146.8 mg/kg으로 동진벼가 제초제 cyclosulfamuron에 가장 민감하게 지상부의 생육이 억제되었다. 또한 cyclosulfamuron은 동일한 농도에서 지상부보다는 지하부의 생육을 더 크게 억제하였으며, 0.3 mg/kg 처리 수준에서 동진벼의 경우 건물 중의 억제정도는 지상부가 4.8% 정도이었으나 지하부는 38.9%이었다. 벼의 acetolactate synthase 활성을 cyclosulfamuron의 농도별로 검정한 결과 공시된 품종간에 큰 차이가 없었으며 50% 억제되는 농도는 화성벼, 동진벼 및 일품벼의 경우 각각 42.7, 32.7 및 56.7 μM이었다. Cyclosulfamuron, a herbicide of sulfonylurea type, is a relatively new compound which control broad leaves and perennial weeds in rice field. However, this herbicide has a minor disadvantage of decreasing rice plant growth, especially in early growth stage. Therefore, for introducing this cyclosulfamuron as a herbicide in rice field, it is important to minimize the suppression of early plant growth with maintaining weed control efficacy. This study was conducted to evaluate effects of cyclosulfamuron on early plant growth and acetolactate synthase activity of rice (Oryza sativa cv Dongjinbyeo, Hwasungbyeo, Ilpumbyeo). Rice growth was inhibited by cyclosulfamuron in their early growth stage. The concentrations required for 50% inhibition of Dongjinbyeo, Hwasungbyeo and Ilpwmbyeo growth were 6.3, 9.2 and 146.8 mg/kg, respectively. Inhibition effect of cyclosulfamuron on the root elongation was greater than the effect on the shoot growth. Concentrations required for 50% inhibition of acetolactate synthase activity from Dongjinbyeo, Hwasungbyeo, Ilpumbyeo were 42.7, 32.7 and 56.7 μM, respectively.

웹 브라우져를 통한 서버 클라이언트 환경의 영상처리 실습 시스템 설계

이병일,손병환,최항묵,최흥국 인제대학교 2001 仁濟論叢 Vol.16 No.1

웹 기반의 환경은 인터넷과 컴퓨터의 접목으로 실생활에서 연구활동에 이르기까지 다양하게 그 효용성의 범위를 굳혀가고 있다. 교육기관에서 활용하는 가상강좌는 이러한 웹의 장점을 활용한 학습방법의 다양화의 결과이다. 본 논문에서 설계한 웹 브라우져를 통한 서버 클라이언트 환경의 영상처리 실습 시스템은 가상강좌나 웹 환경이 구축된 장소에서 교육자와 피교육자사이의 교육효과를 증진시키도록 상호 의사전달의 효율성을 가지게 하는 시스템이다. 각 클라이언트가 다운로드 받은 컴포넌트를 실행하여 구동하게 되면 클라이언트들이 자신의 실습을 위한 프로그램을 로컬에서 가동할 수 있도록 하였기 때문에, 서버측의 부하가 얼어서,실습 결과영상을 로컬 클라이언트에서 부하시간 없이 얻을 수 있게 하였다. 또한 서버의 수정 혹은 갱신으로 바뀌어진 컴포넌트는 클라이언트 측에서 접속시 업데이트가 가능하므로 각 클라이언트에 대한 업 데이트를 따로 고려하지 않아도 되는 장점이 있다. 또한 컴포넌트가 가지는 여러 가지 메쏘드들은 다양한 영상처리의 결과를 볼 수 있게 해 줌으로써 고가의 소프트웨어를 따로 구입하지 않아도 되는 장점을 가지게 된다. The environment of web is applied variously from our life to research activities thanks to the internet and the computer. The virtual lecture utilized by an educational institution is the result of application of a learning system with the advantage of web. In this paper, a design of the image processing training system at the environment of server-client through web browser is the system of high degree of efficiency at the point of communication between lecturer and student. A client can get the result image from another client without load balancing of the server, because the processer for image processing is operated at the container of a client after downloaded as the form of a component. Clients can get the new version of component when they contact, so clients do not need to consider the status of updated component locating in the server. Furthermore, the client can handle an image with the many operations included in component with no purchase of the software additionally, that is another merits of this system.

정병열,임현숙,김봉환 한국수의공중보건학회 2003 예방수의학회지 Vol.27 No.1

We surveyed the prevalence of Listeria spp. in cecal contents of pig and chicken collected from abattoirs. only 4 L. lnnocua isolates were detected in a total of 100 pig samples. From the 100 chicken samples, 47 were confirmed positive for Listeria spp. Twenty eight of these 47 positive samples contained only L. lnnocua; 15 contained both L. monocytogenes and L. lnnocua; 4 contained only L. mnocytogenes. No other Listeria spp. were detected in this study. Listeria spp. were detected in 471115 (40.9%) blackened Fraser broth samples and in 4/85 (4.7%) samples in which Fraser broth did not blacken. Fourteen (73.7%) L. monocytogenes isolates were recovered after 48 h, not 24 h, Fraser broth secondary enrichment.

모든 해결 단일자를 구하는 알고리즘

In AND parallelism, all the links connecting literals in a clause are resolved concurrently. The most general unifiers of all links connected to literals in a clause are obtained first. All the unification can be done in parallel. Obtaining the resolvent using the solution unifier is merely a trivial substitution. The difficult step in AND parallelism is to find all solution unifiers from the given set of mgu's. We can obtain all solution unifiers by getting all combinations of mgu's and checking for consistency and obtaining the solution unifiers for all consistent combinations. Checking for consistency and obtaining a solution unifier for a combination can be achieved by solving multisubstitutons (or multiequations), However, this method is inefficient because it wastes so much time to find solution unifiers of combinations of mgu's which have no solution unifier. We propose an improved algorithm for calculating all solution unifiers of a clause. Our approach is based on the pairwise consistent relation which is similar to the pairwise strongly compatible relation used in subsumption test. For efficient pairwise consistent test, we define the consistent list of mgu's and, by using this lists and appropriate bit operations, we single out unnecessary mgu's and reduce possible combinations of mgu's which have no solution unifier. Furthermore, we provide a new method for consistency test in function-free domain, in which it is not needed to calculate a solution unifier of two unifiers to check for consistency. We also show that a solution unifier of a set of mgu's in function-free domain can be obtained by simple transformation, not by solving multisubstitutions.

This study aims to examine the relationships between multi-facet self-esteem and demographic characteristics of female collegians. Specifically, the purposes of this study are to identify the level of self-esteem of Hyosung female collegians, to test the differences of grade, living, residence, school traffic, religion, circle activity in multi-facet self-esteem, and to test the significances of correlation coefficients between multi-facet self-esteem scores and several traits(the number of siblings, birth order, level of IQ, level of academic achievement, level of college satisfaction, level of department satisfaction, level of library-using, job-satisfaction, level of father, mother education, and level of income). The data of 430 female Hyosung collegians who completed the questionnares were analysed by personal computer using SPSSPC+ packages. The results from the results and discussion were as follows. First, the multi-facet self-esteem scores of Hyosung famale collegians were as usual. Second, in some demographic characteristics grade differences were between sophomores and seniors. Living style and residence had differences in ability, college study, college life area self-esteem. And collegians’ religious activity and circle activity contributes to career and college study positively. Third, there were some close relationships between level of achievement, level of college satisfaction, level of department satisfaction, level of library-using and some area-specific self-esteem. level of father, mother education, and level of income were related to home-enviroment self-esteem. Level of job-getting confidence was related to various domain-specific self-esteem.

광범위하게 진행된 다발성 섬유성이형성증

이병도,황의환,이상래 대한구강악안면방사선학회 2000 Imaging Science in Dentistry Vol.30 No.2

Fibrous dysplasia is a benign disorder of bone consisting of intramedullary proliferation of fibrous tissue and irregularly distributed, poorly developed bone. The disease manifests itself in the monostotic form in which only one bone is involved and the polyostotic form in which multiple bones at different sites are affected. We reported a extensive case of polyostotic fibrous dysplasia with involvement of craniofacial bones, mandible, ribs and extremities. A 18-year-old man showed remarkable right facial swelling who had been treated on right femur 3 years ago with a bone graft for pathologic fracture and he recognized facial swelling 5 years ago. Extraoral radiograms and computed tomogram showed diffuse sclerosis with a ground glass appearance of the most cranial bones, facial bones, The right mandibular lesion showed very expansive lesion with mottled appearance. Bone scans showed mutifocal increased uptakes in craniofacial bones, right mandible, bilaterally in ribs, humerus, femur, tibia and characteristic varus deformity of right femur (shepherd's crook defomity). This case showed exceptionally bilateral, extensive nature of bone lesion and didn't show any features of skin pigmentation and endocrine disturbances.(Korean J Oral maxillofac Radiol 2000 ; 30 : 117-122)
