해양생물다양성 자원에 대한 국가 주권을 인정하는 해양생물다양성협약의 발효로 생물다양성 자원을 확보하기 위한 세계 각국의 경쟁이 치열한 상황이다. 현재 우리나라 각 기관 및 대학들이 보관하고 있는 해양생물자원 정보가 산재되어 있고, DB에 대한 관리 미흡으로 인하여 학술적, 산업적 활용이 어려운 상황임을 인지하여, 통합적으로 관리할 수 있는 정보체계가 필요한 시점이다. 본 논문에서는 해양생물다양성 자원 중 고품질 해양생물자원에 대한 현황을 분석한다. 그리고 해양생물다양성 데이터 고품질 확보 방안을 위한 DB 품질 오류율 산정 기준을 적용하여 메타DB 구축 방안을 제시한다. 본 연구는 향후 해양생물자원에 대한 국가전략수립에 기여할 것으로 기대한다.

The 1972 United Nations Conference on the Human Environment sparked off actions aimed at protecting the ocean on all scales. Physical science was essentially in the foreground, and the ecological dimension remained in the background as well. During the following two decades, ocean uses increased and spread unexpectedly, and there was an urgent need for management patterns to deal with coastal areas, regional seas, and with the ocean as a whole. Meanwhile, mainly thanks to the Man and the Biosphere (MAB) programme, the ecological dimension of the environmental issue became more evident, while the concept of sustainable development was designed by the World Commission on Environment and Development (1987). As far as the ocean is concerned, by adopting Agenda 21, the 1992 Conference on Environment and Development (UNCED) could neither embrace a wholly ecology-oriented policy, nor adopt the concept of sustainable development in its whole extent. This circumstance encourages efforts to consider the ocean from an effective ecological perspective, and to explore how cultural and ecological systems have interacted. Hence the concept of diversity becomes an increasingly key factor.

해양사고 예방을 위해서는 과학적이고 체계적인 해양사고 분석과 평가 및 예측이 우선 필요하다. 이 논문에서는 기존에 연구 개발된 다양한 해양사고 분석과 평가 방법을 검토하였다. 연구결과, 구체적이고 실행 가능한 연구접근 방법과 다양한 분석과 평가기법이 개발되어 있음을 알았다. 특히, IMO의 공식안전성평가(FSA) 절차가 세계적으로 표준화된 규준으로 자리매김하고 있다. 특히, 미국의 유명한 선급 ABS와 노르웨이의 선급 DNV에서 다양한 분석과 평가기법을 보고하였다. 특히, 불확실성이 배제된 위기허용기준(Risk Acceptance Criteria)의 개발이 가장 중요한 요소임을 확인하였다. 향후 해양사고 예방에 적용할 수 있는 고도의 분석과 평가 기법 실용화를 지속 연구할 예정이다.

eDNA, an abbreviation for environmental DNA, means DNA derived from organisms inhabiting in a specific environment. The utilization of eDNA extracted from environmental samples allows for efficient and accurate monitoring of organisms inhabiting the respective environment. Specifically, eDNA obtained from seawater samples can be used to analyze marine biodiversity. After collecting seawater samples and extracting eDNA, metagenome analysis enables the taxonomic and diversity analysis among marine organisms inhabiting the sampled area. This review proposed an overall process of marine biodiversity analysis by utilizing eDNA from seawater. Currently, the application of eDNA for analyzing marine biodiversity in domestic setting is not yet widespread. This review can contribute to establishment of marine eDNA research methods in Korea, providing valuable assistance in standardizing the use of eDNA in marine biodiversity studies.

최근 연·근해 수산자원의 관리 및 어장조성을 통한 자원관리형 수산업으로의 발상 전환과 양식어장의 고도이용 및 생산성 극대화를 위한 기술개발의 필요성이 날로 증대되고 있다. 이와 더불어 세계연안국들에서는 해양목장화시스템의 구상과 관련한 다양한 수중수산시설물의 건설·이용·관리가 빈번해지고 있다. 이에 따라 다양한 수산 증식시설(어초 등), 양식시설, 어장 관리시설 및 부대시설(해저 취·배수관 등)로 구성되는 수중구조물의 종류도 다양하다(D'Itri, 1985). (중략)

The ocean accounts for over 70% of the Earth's surface and is a space of largely unexplored unknowns and opportunities. Korea is a peninsula surrounded by the sea on three sides, emphasizing the importance of marine research. The ocean has an extremely complex environment with immense biological diversity. In terms of microbiology, the marine environment has varying factors like extreme temperature, pressure, solar radiation, salt concentration, and pH, providing ecologically unique habitats. Due to this variety, marine organisms have very different phylogenetic classifications compared with terrestrial organisms. Although various microorganisms inhabit the ocean, studies on the diversity, isolation, and cultivation of marine microorganisms and the secondary metabolites they produce are still insufficient. Research on bioactive substances from marine microorganisms, which were rarely studied until the 1990s, has accelerated in terms of natural products from marine Actinomycetes since the 2000s. Since then, industries for bioplastic and biofuel production, carbon dioxide capture, probiotics, and pharmaceutical discovery and development of antibacterial, anticancer, antioxidant, and anti-inflammatory drugs using bacteria, archaea, and algae have significantly grown. In this review, we introduce current research findings and the latest trends in life science and biotechnology using marine microorganisms. Through this article, we hope to create consumer awareness of the importance of basic and applied research in various natural product-related discovery fields other than conventional pharmaceutical drug discovery. The article aims to suggest pathways that may boost research on the optimization and application of future marine-derived materials.

In this paper, we propose a standardization strategy for next generation electronic navigational chart which can be classified as S-100 Universal Hydrographic Data Model, to accept various requirements arising from various marine information and services as well as support e-navigation service strategies. IMO uses the next generation electronic chart standard, S-100 as Common Maritime Data Structure. It means that a common data model is needed as a key element for realization of e-Navigation and also points out that a new ICT convergence paradigm is needed not only for marine safety but also for maritime information and services. this paper considers he model-based data representation and reference model in order to understand the content and use of the S-100 standard and also considers the interconnectivity and role of the ISO/TC211 standards, which are being used as base standards for profiling to develop S-100 standard. Finally, we look at what standardization items are required for standardization of next generation electronic navigational chart supporting multi-purpose and how they are used mutually.

Bacteria play an important role in biogeochemical cycles in marine environments and their functional attributes in ecosystems depend primarily on species composition. In this study, seasonal variation of bacterial diversity was investigated by pyrosequencing of 16S rDNA in surface sediment and overlying seawater collected in the south East Sea, planned for the site of $CO_2$ sequestration by the carbon capture and storage (CCS) project. Gammaproteobacteria was dominant in the sediment in most seasons, whereas Alphaproteobacteria was a most dominant group in the overlying water. Thus, the bacterial diversity greatly differ between sediment and seawater samples. On the genus level, bacterial diversity between two habitats was also different. However, the number of genera found over 5% were less than 10 in both habitats and the bacterial community was composed of a number of diverse minor or rare genera. Elevation of $CO_2$ concentration during a $CO_2$ storage process, could result in change of bacterial diversity. Thus, this study will be very useful to access the effect of $CO_2$ on bacterial diversity and to predict functional change of the ecosystem during the process of CCS project.
