Harmful shell-boring species of the genus Polydora (Polychaeta: Spionidae) were frequently reported from commercially important mollusk species in Korea, Japan and China. The traditional approach based on the morphological characteristics showed limitations for species discrimination among shell-boring species. Therefore, DNA barcoding was adopted to identify Polydora species using molecular markers. Two Polydora species (P. haswelli and P. hoplura) in abalone shells were reported from our previous molecular phylogenetic study. In this study, we additionally reported the presence of shell-boring Polydora haswelli in commercially sold shellfish. The taxon-specific cox1 marker used in this study successfully allowed the isolation of P. haswelli from cockle Scapharca subcrenata, mussel Mytilus galloprovincialis, oyster Crassostrea gigas and scallop Argopecten irradians. Polydora hoplura was not found in these shellfish species. The genetic variations were found on the intraspecific level of P. haswelli and the same genotype was also detected in different shellfish species. This result can provide information on a new host and accurate parasitic Polydora species. Moreover, this report can be used as the biodiversity data of Polydora species on the invasion and transition of harmful Polydora species in mollusk aquaculture farms.
Real Time Playback을 이용한 EMTP-RV와 PSCAD/EMTDC의 출력 데이터 비교 분석

본 논문에서는 Real Time Playback(HTP)을 이용하기 위하여 EMTP-RV와 PSCAD/EMTDC의 출력 데이터를 비교분석하였다. IEEE 13 Node Test Feeder를 EMTP-RV와 PSCAD/EMTDC로 모델링한 후 1선 지락사고를 모의하여 출력데이터를 RTP에 입력하였다. 이 데이터를 이용하여 RTP 이용 시 두 가지 방법에 대한 여러 가지 성능을 비교분석 하였다.
