Tributyltin Compound in Sediments and Tissues of Oysters and Rock Shell in Gwangyang Bay, Korea
심원준,임운혁,김남숙,홍상희,오재룡 한국환경생물학회 2004 환경생물 : 환경생물학회지 Vol.22 No.-
- Tributyltin (TBT) and its degradation products, dibutyltin (DBT) andmonobutyltin (MBT) were quantitatively determined in surface sediments and twomolluscan species, Pacific oyster ( Crassostrea gigas ) and rock shell ( Thais clavigera ),from Gwangyang Bay, Korea. Butyltin compounds were detectable in almost all sedi-ment and biota samples. Tributyltin concentrations in surface sediment ranged 2~ 33ng g-1, which is at a lower end of TBT concentrations in industrialized bays in Korea.However, TBT levels in sediments were related to boating activities around the bay. Inbiota samples, TBT concentrations were in the range of 178 ~ 2,458 ng g-1 for oyster and47~ 236 ng g-1 for rock shell. Relatively high TBT concentrations in biota were foundnear wharves for fisherboats and harbor areas. About 90 ~ 100% of the female T. clav-igera displayed imposex, and relative penis length index of the imposexed -female wasin the range of 20.9 ~ 107.9%. Furthermore, TBT body residue had a significant positiverelationship with degree of imposex in T. clavigera . Overall, TBT concentrations inGwanyang Bay were much lower than other major bays in Korea.

Ocean Science Journal indexed in the Science Citation Index Expanded
심원준 한국해양과학기술원 2014 Ocean science journal Vol.49 No.2
It is my great pleasure to announce that Ocean Science Journal (OSJ) has been recently selected for a coverage in the Science Citation Index Expanded™ (SCIE) and Journal Citation Reports/Science Edition (JCR) bibliographic and citation databases. Indexing of OSJ covers from its first issue in 2005. The journal will soon receive a Journal Citation Impact Factor. We believe the visibility, recognition and citation of papers in OSJ will increase by this indexing. Until OSJ was indexed in SCIE, members of the OSJ Editorial Board devoted themselves to mold OSJ as a world-class scholarly journal representing Asia. They maintained fair but stringent review processes to significantly improve the quality of manuscripts. Especially, we focused on inviting outstanding manuscripts from Asian scientists with a goal to specialize in Asian regional seas research. Since 2010, OSJ marked a new era of publication by entering into a strategic parnership with Springer. This partnership enabled worldwide distribution of OSJ. I would like to thank everyone who contributed in so many different ways to achieve this great success. Especially, I am truly grateful to all members of the Editorial Board for their devotion, our reviewers for exerting the most powerful impact on the quality of the journal, and all authors for submitting their invaluable research outcomes to OSJ. We believe that OSJ will become an essential journal for scientists in the world. We look forward to your continuous supports and contributions to OSJ.

Application of a Sediment Quality Index to the Masan Bay, Korea
심원준,홍상희 한국해양과학기술원 2007 Ocean and Polar Research Vol.29 No.4
A sediment quality index (SQI) and a mean sediment quality guideline quotient (M-SQGQ) were applied for the assessment of sediment quality in Masan Bay, Korea where metals and organic pollutants are of concern. The SQI was calculated by two functions, 'scope' (the number of variables that do not meet guideline objective) and 'amplitude' (the magnitude by which variables exceed guideline objective), with six different sediment quality guideline values from Canada, USA and Australia/New Zealand. Categorization of sediment quality was on the basis of SQI scores. The SQI values were compared with six guideline values applied as well as with the M-SQGQs. The SQI values were severely influenced by a few variables of high exceedance in the degree of non-compliance. The SQI values were very dependent on both the numbers and values of guideline variables used in index caluculation. Nevertheless, the SQI could provide integrated and simplified information from a large number of chemical data set. It is required to further evaluate protocols and guideline applied for deriving SQI and to compare it with field based sediment toxicity test and ecosystem integrity.
