본 연구는 2004년은 한국에서 개최된 APCG 8(The 8th Asia-Pacific Conference on Giftedness, 2004)을 통하여 일반 영재교육의 최근 동향을 탐색하였다. 1980에서 2002년까지의 ERIC(Education Research Information Center)에 나타난 수학영재관련 문헌을 검색하여 644개를 선정 분석하여 그 연구 동향을 파악하고, 2003년에서 2004년까지는 ICME 10(the 10th International Congress on Mathematical Education, 2004)과 ICCME&EGS'03 (The Third International Conference Creativity in Mathematics Education and the Education of Gifted Students, 2003)을 통하여 수학영재교육의 최근 연구 동향을 분석하여 수학영재교육 발전과 활성화에 도움을 주는데 목적을 두고 있다.

DNA fingerprint patterns of 8 Brucella reference strains and 15 B. abortus field isolates were characterized by repetitive element sequence-based PCR (rep-PCR) using BOX- and ERIC-primers in this study. AMOS PCR differentiated all Brucella field isolates from B. abortus RB51, a vaccine strain by producing a B. abortus-specific 498 bp band. Rep-PCR using BOX-primer produced 13 to 18 bands with sizes of between 230 and 3,300 bp, and discriminated Brucella strains to the species level except B. canis and B. suis. PCR products amplified with ERIC primers were, however, not appropriate for differentiating the Brucella isolates. DNA fingerprint patterns for all B. abortus field isolates were identical among them and were put on one cluster with B. abortus biovar 1 reference strain in the dendrogram, indicating they were highly clonal. These results suggested that rep-PCR using BOX primer might to be a useful tool for calculating genetic relatedness among the Brucella species and for the study of brucellosis epidemiology.
