Dokdo, a group of 33 small and rocky Islets, in the East Sea have been administered by Korea for years since 1953 and are currently occupied by Korean Police Unit. Located about 217Km off the eastern border of Korea and 87Km east of UIleung Island in North Gyeongsang Province. Situated in the East Sea of Korea, Dokdo itself has valuable strategic implications for Korea as well as another countries such as Russia, Japan, U.SA etc. The first historical testimonies to Dokdo were in Korean documents referring to it as a part of an independent island district known as Ulleung Island(Usanguk), which was incorporated into Silla Kingdom in 512 A.D. in '1454 Sejong Authentic History'. Historically, since at least 1881, the island has been called Dokdo by Koreans, meaning 'Rock Island' or 'Lonely Island'. Also Korea, which regained a full sovereignty and have exercised it for decades continuously, keeps a small police detachment on the Island. That is, Dokdo is under effective control of Korea until today. Therefore Dokdo, which is a problem that is related to our territory and sovereignty, is clearly a cluster of Islands of Korea.

Recently, there are severe tension between Korea and Japan around Dokdo area. Because the marine resources near Dokdo are much plentiful. Especially, development of deep sea water and natural gas are hopeful in this area. In order to preoccupy a development plan of marine resources, many scientific investiment for ocean research are needed. We must have continuous concern about marine resources near Dokdo area.

Bacteria were isolated from roots of plants belonging to family Solanaceae and Gramineae, inhabited in Dokdo island. Fifty six endospore-forming bacteria grown on tryptic soy broth (TSB) agar medium and 23 nitrogen-fixing bacteria (NFB) grown on nitrogen free agar medium were isolated, respectively. The isolates were partially identified by analyzing the 16S rDNA and categorized into phylogenetic groups. The 16S rDNA sequences of each identified isolates were compared with sequences of each type strains to analyze phylogenetic relationship by phylogenetic tree. As a result, endospore-forming bacteria and nitrogen-fixing bacteria were classified into 4 and 6 lineage groups, respectively. Among these isolated, 18 were presumed to be novel species candidates based on the similarity (lower than 98%) analysis of the l6S rDNA sequences.

To understand the function of nursery grounds, the seasonal variation of ichthyoplankton was investigated in the East Sea, off Dokdo, from September 2009 to May 2010. The dominant species was Engraulis japonicus (92.7%), which occurred in May and September. The next abundant species was Maurolicus japonicus (5.7%), found in all four seasons. Several rare warm-water species were found in September and November, when the species diversity was higher than in the other two seasons. Several fish species used Dokdo as a nursery ground for a restricted season, while M. japonicus used it in all four seasons.

Ichthyoplankton (fish eggs and larvae) were collected seasonally collected from 2017 to 2019 to clarify whether Dokdo serves as a fish spawning and/or nursery ground. Fish eggs were identified and classified into 16 species. The dominant fish egg species were Engraulis japonicus, Maurolicus japonicus, and Parajulis poecilepterus. Fish larvae were identified and classified into 15 species. The dominant fish larvae species were E. japonicus, M. japonicus, and Sebastes owstoni. A cluster analysis similarity percentages revealed two distinct groupings according to sample location (stations) with E. japonicus and M. japonicus as the main group influencers. E. japonicus was the dominant species off Dokdo. The species diversity and abundance peaked in summer. The diversity index, richness index, and evenness index fluctuated seasonally. There were no predominant species variations among the years. Sedentary species such as P. poecilepterus, Semicossyphus reticulatus, and Glyptocephalus stelleri occurred in the inshore stations. E. japonicus, M. japonicus, and Trachipterus trachypterus occurred in the offshore stations. Our results show these species use Dokdo as spawning and nursery grounds.

독도 지명의 변천과 표기의 다양성을 고찰하고, 이를 바탕으로 54개 국가도서관의 목록레코드를 조사하여 독도관련 자료의 표기 실태 및 특성을 비교 분석하였으며, 결과를 요약하면 아래와 같다. 첫째, 독도관련 자료가 대부분 미국, 호주, 영국 등 일부 특정 국가도서관에 집중되어 있는 반면, 한 건도 검색되지 않은 곳이 5개관에 달했다. 둘째, 각국의 국가도서관에서 독도관련 자료의 표제 키워드는 한국에서 독도를 지칭하는 용어인 '독도'로 표기한 경우가 76.1%, '다케시마' 17.6%, '리앙쿠르암' 0.4%, 이들 용어의 병기가 5.9%로 나타났다. 셋째, 각국의 국가도서관에서 독도관련 자료가운데 '독도(한국)' 또는 '독도'라는 의미로 주제명을 나타낸 경우가 54.9%, '다케시마(일본)' 또는 '다케시마' 11.2%, '리앙쿠르암'과 '독도/다케시마' 병기가 각각 1% 미만, 일반주제명이거나 주제명이 나타나 있지 않은 경우가 33%로 나타났다.

Thirteen decapod crustaceans of Dokdo Island were identified and classified based on samples collected around Dokdo Island from May 1999 to November 2004. Of the 13 species, 7 were unrecorded from Dokdo Island: Axiopsis princeps, Pagurus angustus, Pagurus japonicus, Pagurus nigrivittatus, Pagurus spina, Portunus trituberculatus, and Hemigrapsus penicillatus. Of these 7 species, Pagurus nigrivittatus and Pagurus spina were new to the Korean decapod fauna. However, P. spina was only reported as the type series from the Pacific coast of northern Japan. Its geographic range now extends to the East Sea. To date, 25 decapod crustaceans (1 caridean, 1 thalassinidean, 11 anomurans, and 12 brachyurans) have been reported from Dokdo Island.

A two-year survey on the insect fauna of Dokdo located at the eastern end of Korean territory, was carried out from 2009 to 2010. A total of 11 Orders 65 Families 131 Genera 133 Species of insects was reported to exist in Dokdo by Park et al. (2012). This study was focused on the collection of small insects (under 1 mm in body length) in Dokdo. Form the collection, the comparison of the species composition to past records in Dokdo was carried out.

독도는 약 $300{\sim}220$만 년 전에 형성된 해양섬 기원의 화산체로서 동도와 서도로 구성되어 있다. 비록 규모는 작지만 동해의 형성 및 진화와 연관된 지질과학적 중요성 외에 자원적, 생태적, 영토적 가치, 그리고 일본과의 독도 영유권 문제와 관련한 국민적 관심 등 경제 사회 과학 기술적 측면에서 무한한 잠재적 가치와 의미를 갖고 있는 지역이다. 최근 동도 육상부에서 급속하게 진행되고 있는 풍화 및 침식작용으로 인한 각종 균열로 인하여 독도 지반의 안정성 평가의 필요성이 제기되었다. 본 논문은 독도의 지반안정성 분석을 위한 사전조사단계로서 독도의 지질과 층서, 지반불안정을 발생시키는 요인에 대하여 알아보고 육안관찰에 의해 위험요소로 판단된 지역에서 수행되었던 독도 암석의 역학적 특성을 분석하였다. 독도의 암석은 주로 응회암, 조면암, 조면안산암으로 구성되어 있으며, 전체적으로 풍화와 침식에 의해 국내 암석의 역학적 물성수치에 비해 상대적으로 낮았다.

독도에 대한 연구는 여러 분야에서 수행되고 있으나, 독도의 해양연구 자료에 대한 체계적인 관리와 지속적인 축적이 미흡한 실정이다. 특히 독도 및 독도주변해역의 해양환경 및 해양생태계 등 해양과학 자료의 체계적인 데이터베이스가 구축되지 못하였다. 따라서 독도 해양조사자료의 체계적인 관리와 효율적인 활용을 위한 공간기반의 GIS 데이터베이스 구축이 요구되며, 이를 수행하기 위한 설계 단계에서 GIS 기반의 해양데이터 모델 수립이 필요하였다. 본 연구에서는 기존의 해양관측자료를 수집하여 데이터 종류와 특성에 따라 GIS 기반의 프레임워크 자료(framework data), 연구조사자료(research data) 및 주제도 자료(thematic data) 등 세 개의 그룹으로 분류하였다. 또한 각 연구조사자료의 속성은 GIS 프레임워크 자료와 연계되도록 설계하였다. 이와 같은 통합적인 GIS 데이터 모델 수립의 연구 결과는 향후 독도 뿐 아니라, 다른 해역에서 관측된 해양연구자료의 관리시스템 개발에도 적용될 수 있을 것이다.
