생물학적 유전자 배열에서 다양한 레벨로 분자 세포 간 네트워크를 입증하여 고 처리를 응용하여 수치학적인 표현 모델 분석으로 정보공학 네트워크를 연구한다. 확률적 그래프 모델을 사용하여 네트워크의 계층적 구성 특성을 이용하여 생물학적 통찰력을 확률함수를 응용해 복잡한 세포 간 네트워크에 대한 고 대역 처리 데이터의 근원인 DNA 마이크로 배열을 응용하여 유전자 베이스네트워크 논리를 유전자 표현 레벨로 나타낸다. 유전자 데이터로부터 확률적 그래프 모델들을 추정 및 분석하고 논리적으로 예측하여 확률적 그래프 모델이 정보공학 네트워크로 확장 추론 한다.

Currently, oriental medicine research is focused with modern research technology and validate it's various biochemical effect by combining with molecular biology technology. But there are few searching system for finding biochemical mechanism which is related to major compounds in oriental medicine. In this research, we aimed developing korean herb database based on text-mining system by analyzing PubMed data. We have developed prototype system for searching chemical, gene and biological relation in oriental medicine. It is characterized by modern oriental medicine research trend with major chemical, gene and protein information. Analysis results can be searched on the prototype system with visualization of the biological interactions.

화학적 산화처리와 bioremedation 기법을 개별적 또는 복합적으로 동시에 적용함으로써 한 개별 기법의 단점을 보완하고 현장적용성을 증대시킬 수 있는 통합기법을 개발하고자 하였다. 펜톤유사 반응을 통해 고농도의 유류를 산화분해 시킨 후 미생물 처리를 통해 잔류 유류 오염물질을 제거하고자 하였다. 유류 오염토양의 화학 생물학적 통합처리 공정의 현장 적용성 및 토양 미생물에 미치는 영향을 검증하기 위해 처리과정 전 후의 미생물 군집구조를 분석하였다. 또한 토양 내 유류 분해균을 분리하기 위해 탄소원으로 경유와 벙커C를 이용하여 농화배양을 수행하였다. 경유 분해균 10여종, 벙커 C 분해균 6종을 분리하여 분해능 및 동정을 시도하였다. 또한 유류 분해미생물의 consortia를 분자생물학적 기법으로 분석을 시도하였다.

A systematic review for Korean Liliopsida was carried out with rbcL and atpB sequence data. Congruent phylogenetic trees were obtained from two different data sets. Korean Liliopsida consists of the three orders, Asparagales, Liliales, and Dioscoreales sensu Dahlgren et al. Members of Dioscoreales were used as an outgroup for inferring relationships among Asparagales and Liliales in the molecular studies. Iridaceae showed close relationship to Asparagales both in the rbcL and atpB sequence trees rather than to Liliales. Family Nartheciaceae (previously included within Melanthiaceae s. lat.) appeared as a paraphyletic assemblage basal within Liliales, but did not show relationships to other orders. Genera of Ruscaceae (previously Convallariaceae) like Disporum, Clintonia, and Streptopus had to be transferred to Colchicaceae, Liliaceae, and Calochortaceae, respectively. A revised list of families for Korean members of Liliopsida is suggested.

‘바이오칩(biochip)’ 이란 컴퓨터 칩(computer chip)에서 유래되어 바이오(bio)와 관련된 어떤 집적회로의 요소와 관련된 용어로 지칭되어 왔으나, 최근 몇년 동안 기술개발이 구체으로 이루어 지면서, DNA를 포함한 생체분자(biomolecule)에 대하여 생화학적 분석에 사용되는 프로브(probe)를 정렬(array)시킨 물질 및 장치라고 정의되고있다.(중략)

Recently, it has been reported that low molecular weight laminarin had the enhanced biological activities. In this study, molecular structure of low molecular weight laminarin prepared by ionizing irradiation was studied. Low molecular weight laminarin samples of 13.5, 8.5, 7, and 6 kDa were obtained from 15 kDa laminarin by irradiation. From gel permeation chromatography data, low molecular weight laminarin was shown to have low polydispersity. To define the changes of functional groups in laminarin with different molecular weights, Fourier-transform infrared analysis was carried out. There was found no significant changes of functional groups in low molecular weight laminarin, except the increase of carbonyl group. The granular fissures from scanning electron microscopy showed the breakage of glycosidic bond in low molecular weight laminarin. These results could be utilized for the investigation of the enhanced biological activities of low molecular weight polysaccharides including laminarin.

Han River is very important as a source of drinking water in metropolitan area. This study was conducted to figure out diversity and dynamics of plankton community in the seven lakes (lakes Paro, Chunchon, Soyang, Uiam, Chungpyung, Paldang, Chungju) of Han Riversystem. A total of 76 genera and 121 species were investigated by taxonomic identification in November 2008. Cyclotella sp. and Microcystis sp. was a dominant species in lake Paro and Chungju respectively. Aulacoseira granulata was dominant in lakes Chunchon, Paldang and Chungpyung. And Fragilalia crotonesis was a dominant species in lake Soyang and Uiam. Our results can be useful when compared to the results using molecular biological method to supplement taxonomic identification.
