Increased attention has been paid to the presence of veterinary antibiotics in various environmental matrices due to their toxicological behavior in the ecosystem and development of antibiotic-resistant strains of pathogenic bacteria. In the this review, 37 target antimicrobials were selected based on annual sales of antibiotics for livestock in South Korea 2014. Also, extraction and clean-up methods for the determination of the antibiotic residues in liquid samples including water, milk, and honey were comprehensively reviewed in the literature. Solid-phase extraction (SPE) was commonly used as a pre-treatment method for the samples. Most of the analytes were extracted in acidic conditions (2.5~4.0) except for aminoglycosides, which were extracted in neutral conditions (7.0~8.0). ${\beta}-Lactams$ showed the highest recoveries in neutral pH due to their degradation characteristics in acidic media. Starta-X, Oasis HLB, and Oasis MCX were frequently applied as an SPE cartridge and Oasis HLB showed the highest recoveries for the majority of antibiotic classes. The homogenized honey and milk were extracted by mixing with acids for deproteinization. Solids and other interfering substances in the extract were eliminated by centrifugation followed by membrane filtration or SPE before injection into HPLC.

Objectives: The purpose of this study was to examine trends in duplicate publication in Korean medical articles indexed in the Oriental Medicine Advanced Searching Integrated System(OASIS). Methods: We searched the list of papers published in Korean medical journals by using OASIS. We randomly extracted 10% of total articles (n=1,162). We searched using OASIS by entering keywords from the title and names of the first and last authors of each indexed article. After the librarian selected the candidates of duplicate publication, three authors reviewed the full texts of the articles independently. When their opinions were not in agreement, reconciliation was made by discussion. The patterns of duplicate publication, such as copy, salami slicing (fragmentation), and aggregation (imalas), were also determined. Results: A total of 1162 articles were evaluated, 24 (2.1%) index articles of which were duplicate articles. Among 24 index articles, Two were triple publications and 22 were double publications. The patterns of duplication publication were as follows; (1) copy (n=8, 33.3%); (2) salami (9, 37.5%), (3) imalas (5, 20.8%) (4) others (2, 8.3%). Conclusion: Duplicate publications have appeared in Korean medical journals in a small proportion. Education on publication ethics and authors'ethical awareness is needed.

The historical, social, and cultural value of Internet resources is indisputable, therefore many national institutions have created Web archiving projects to hand down this heritage to future generations. The selection guidelines are the most crucial aspect of these projects because they aid in differentiating which resources are worth collecting and preserving from the large number of web resources available. The purpose of this study was to suggest improvements for the OASIS Selection Guidelines by analyzing the selection guidelines of other domestic and international Web archiving projects. First, based on the results of Web archiving projects abroad, we proposed improvements for the definition of Web data and other terms, the basic principles of the collection, collection methods, and collection cycle. Second, we proposed substantial improvements in the target resources for archiving, and also stated what kind of web resources must be excluded from Web archiving. Finally, we discussed the relationship between data collection methods and the legal deposit of online resources, the necessity of constructing a database for selected target materials, and the necessity of cooperative archiving policies.

This study aims at discussing development of web archiving policies in South Korea. The study is based on the understanding of that the institutional environment and efforts for keeping Web information resources are insufficient, compared to the value and importance of them. For the study, Web archiving practices are analyzed into three aspects: scope, method, and quality. Futhermore, they are graphically schematized as a comparative analysis model. Based on the model, the study classifies national Web archiving practices into seven unique types and diagnoses their cons and pros. In this context, a combined Web archiving policy is discussed as an optimal Web archiving approach. As a case study, the France National Library's Web archiving is discussed in depth and the Korean National Library's Web archiving project, OASIS, is critically analyzed. As a result, the study proposes two alternative plans for the development of Web archiving policy in South Korea.
