국내에서 육성된 옥수수 90 품종 및 자식 계통에 대하여 microsatellite 마커를 활용하여 DNA 프로파일 데이터베이스를 구축한 다음 공시품종에 따른 유전적 유사도 분석 및 품종식별력 검정에 대한 연구를 수행하였다. 옥수수 90품종을 100개의 microsatellite 마커로 검정하고 대립유전자의 패턴이 우수하고 다형성 정도가 높은 13개를 선정하여 분석하였을 때 대립유전자의 수는 5 ~ 24개까지 다양하게 분포하였고 평균 대립유전자의 수는 13.69개로 높았다. PIC 값의 경우도 0.716 ~ 0.942 범위에 속하였고 평균값은 0.865로 아주 높았다. 옥수수 90품종 및 계통에 대하여 UPGMA 분석에 의한 계통도를 작성하였을 때, 옥수수의 품종 유형 및 품종 육성 계보에 따라 5개의 대그룹으로 나누어졌다. 본 연구에서 구축됨 옥수수 자식계통 및 품종별 microsatellite DNA 프로파일 데이터베이스는 신품종과 기 육성된 품종과 유전적 유사도 분석이 가능하기 때문에 품종보호출원시 대조품종 선정 및 품종진위성과 관련된 종자분쟁에 매우 유용하게 활용될 수 있을 것이다.

본 연구의 목적은 식용 및 약용버섯인 아위(阿魏)버섯(Pleurotus ferulae) 균주와 느타리버섯속(Pleurotus spp.) 종간의 유전적 유연관계를 이해하는 것이었다. RAPD 분석결과 이들 버섯 종들은 유사도 80% 수준에서 7개의 그룹으로 분류되었다. 노랑느타리(P. cornucopiae), 사철 2호(P. florida), 여름 2호(P. sajor-caju)는 각각의 그룹으로 분류 되었고, 큰느타리 균주인 26060과 P. fuscus var. ferulae 균주인 26065은 같은 그룹으로 분류되었다. 4개의 느타리 균주는 흑평을 제외한 수한 1호, 원형 1호, 춘추 1호가 한그룹을 형성하였고, 아위버섯 균주 중 일본설이를 제외한 박달, 아위, 천산 1호, 아위예산 균주가 하나의 그룹을 형성하였다. 아위버섯 균주인 일본설이는 느타리 균주인 흑평과 같은 그룹에 속하였다.

상업적 가치가 높고 양식 가능성이 있는 백합과 5종을 대상으로 RAPD방법을 이용한 개체간의 유전적 유연관계를 조사하였다. DNA 추출은 protein K-phenol방법을 사용하여 각 종의 후폐각근에서 추출하였다. RAPD-PCR결과 15개의 primer들이 증폭되었고, 그들로부터 각각 1-3개의 band를 볼 수 있었다. 백합과 5종간 유전적 유사도는 살조개와 바지락간에는 0.84, 개조개와 백합간에는 0.87로 각각의 두 종간에는 놓은 유사도를 보였고, 가무락조개는 살조개와 바지락간에 0.78의 유사도를 보였으며, 개조개와 백합, 살조개, 바지락, 가무락조개간에는 0.46의 비교적 낮은 유전적 유사도를 보였다. RAPD 방법으로 종내개체 유전변이를 파악하기는 힘들어도, 양식이나 자원증식을 위한 패류의 우수형질 선택에 있어 기본 정보를 제공 할 수는 있을 것이다. 또한, 살조개 대량종묘생산의 방법은 유전적 유사도가 가장 가까운 바지락을 중심으로 이루어져야 할 것으로 사료된다.

Genomic DNA from the muscle of marsh clam (Corbicula leana) from Gochang was extracted in order to identify genetic differences and similarity by randomly amplified polymorphic DNAs-polymerase chain reaction. 3.28 of the 23.0 polymorphic bands per lane were found to be polymorphic in marsh clam. Also, about 4.34% of total polymorphic bands were either specific to marsh clam. The major common bands of 0.28 kb generated by primer OPB-15 (GGAGGGTGTT) were present in every individuals, respectively, which were polymorphic. This common bands which present in every individuals should be diagnostic of specific strains, species and/or their relatedness. Primer OPB-19 (ACCCCCGAAG) produced the highest number of specific bands, which was 12. The specific minor band of 0.07 kb was present in lane 22, which were polymorphic. Especially, only a specific band (1.35 kb) identifying individuals was observed in lane 22.

The part family (PF) formation in a cellular manufacturing has been a key issue for the successful implementation of Group Technology (GT). Basically, a part has two different attributes; i.e., design and manufacturing. The respective similarity in both attributes is often conflicting each other. However, the two attributes should be taken into account appropriately in order for the PF to maximize the benefits of the GT implementation. This paper proposes a clustering algorithm which considers the two attributes simultaneously based on pareto optimal theory. The similarity in each attribute can be represented as two individual objective functions. Then, the resulting two objective functions are properly combined into a pareto fitness function which assigns a single fitness value to each solution based on the two objective functions. A GA is used to find the pareto optimal set of solutions based on the fitness function. A set of hypothetical parts are grouped using the proposed system. The results show that the proposed system is very promising in clustering with multiple objectives.

AFLPS (amplified fragment length polymorphisms) were used to estimate the genetic diversity of seven populations of Brassica campestis L. ssp. napus var. nippo-oleifera Makino between naturalized and cultivated populations. The seven Korean populations maintained a high level of genetic diversity. For example, all eight primers were high polymorphic, with an average of 3.2 effective alleles per primer set, and the expected heterozygosity was also high. The majority of genetic variance resided within populations The combinations of an insect-pollinated, outcrossing breeding system, large populations sizes, a high degree of gene flow and a propensity for high fecundity may explain the high level of genetic diversity within cultivated populations. Estimates of genetic similarity on the proportion of shared fragments ranged from 0.952 to 0.999. The high level of gene flow In Korean naturalized populations is mainly caused by seed dispersal via sea tide and the gene flow of cultivated populations may be enhanced in part by artificial pollen dispersal.

Clustering of data is of a great interest in many data mining applications. In the field of document clustering, a document is represented as a data in a high dimensional space. Therefore, the document clustering can be accomplished with a general data clustering techniques. In this paper, we introduce a document clustering system based on similarity among documents. The developed system consists of three functions: 1) gatherings documents utilizing a search agent; 2) determining similarity coefficients between any two documents from term frequencies; 3) clustering documents with similarity coefficients. Especially, the document clustering is accomplished by a hybrid algorithm utilizing genetic and K-Means methods.

In this paper, we attempt to prevent certain cases by tracing a history and making genogram about open source software and its modification using similarity of source code. There are many areas which use open source software actively and widely, and open source software contributes their development. However, there are many unconscious cases like ignoring license or intellectual properties infringe which can lead litigation. To prevent such situation, we analyze source code similarity using program dependence graph which resembles subgraph isomorphism problem, a typical NP-complete problem. To solve subgraph isomorphism problem, we utilized harmony search of metaheuristic algorithm and compared its result with a genetic algorithm. For the future works, we represent open source software as program dependence graph and analyze their similarity.
