The feeding habits of Sebastes schlegeli collected from the Tongyeong marine ranching area throughout 2002 were studied. S. schlegeli is a carnivore (piscivore), and consumed mainly fish. Its diet also included a small amount of caridean shrimps, crabs, amphipods, polychaetes, and isopods. The diet of S. schlegeli underwent size-related changes. Small individuals (standard length (SL)<6 cm) fed mainly on fishes, caridean shrimps, and amphipods, and the proportion of fish increased with SL. Large individuals (SL>20 cm) ate fish predominately. The diet of S. schlegeli changes seasonally, and caridean shrimps were consumed mainly from May to July. The dietary breadth index of S. schlegeli varied with SL and season.

Cell number of Vibrio spp. was examined for the surface and bottom sea water harvested from the 9 stations in the Jeonam Archipelago Marine Ranching Ground in 2006～2007. Species population composition and dominant species were analyzed as well. The largest number of Vibrio spp. was detected in summer (June, 2007) among the 4 seasons with the surface and bottom sea water samples of 5.4～93.2 cfu㎖-1 and 1.0～53.1 cfu㎖-1. respectively. In winter (January, 2007), Vibrio spp. was not detected at all except that one station from which 0.2 cfu㎖-1 of Vibrio spp. was counted in the surface sea water sample. Cell numbers were 0～11.9 cfu㎖-1 and 0～8.3 cfu㎖-1, respectively, in the surface and bottom sea water samples retrieved in spring (April, 2007), and the corresponding sea water samples in autumn(November, 2006) were contaminated with 0.1～21.4 cfu㎖-1 and 0～2.9 cfu㎖-1, respectively. Species population composition of Vibrio spp. was found to be V. parahaemolyticus, V. alginolyticus and V. cholerae non-01 among which V. parahaemolyticus and V. alginolyticus were dominant in all seasons. V. alginolyticus was detected from all stations even in the winter season indicating that this species seems to be less temperature dependent than the other Vibrio spp..

The purpose of this study is to introduce United States Coast Guard (USCG) in order to suggest a direction to advance the system of Korea Coast Guard. After the effect of United Nations on the Law of the Sea in 1994, the world is facing with new era of maritime age with emergence of new maritime border 'Exclusive Economic Zone(EEZ)'. Along with new maritime era, Korea also has been facing with the conflicts caused from EEZ. Also, there is a increasing concern about maritime safety and security since people looking for maritime tourism and leisure sports are dramatically increasing in Korea. Moreover, national security matters are a big issue in Korea due to the several incidents occurred in the sea such as the attack on Yeon-Pyung Island and the sinking of Cheonan naval vessel. Arising concern on these issues in maritime space requires Korea Coast Guard to handle these effectively. However, the systematical and structural limitation of Korea Coast Guard limits the effective management of recent issues. The United States Coast Guard which is considered as one of the military force in the United States has continuously reformed and developed its system and structure to better handle the maritime safety and security issues through developing project such as the Integrated Deep Water system. Also, maritime police system and structure in the United States is different with in Korea. This study expects to suggest a way to advance the system and structure of Korea Coast Guard through examination of United States Coast Guard and comparing maritime police system and structure between Korea and the United States in order to properly deal with the maritime safety and security issues arising recently.

Donghaean Byeolsingut itself reflects the ideals and dreams of seaside life. Imagination and interest in water are fully reflected in Donghaean Byeolsingut as a living in a seaside town. For the beach people, water is the foundation of life and the object of fear. It is the water of life and the water of death. It projects the whole process of life into the imagination created by the world encompassed by the sea. The beach's imagination is an existential insight into the whole process of life and a reflection of existential agony. At Poongeoje, the villagers hope for a specific blessing from God. People are free only when God's retribution comes down. The villagers feel free because of the virtue of the shaman's blessing. Individual trauma is experienced to a certain extent by gaining mental freedom. It can be said that the state of aesthetic pleasure experienced by creating an art work by itself and the nature of aesthetic pleasure experienced through Pungeoje and Byeolsingut are not different. The prototype of Poongeoje is a free spirit, and a religious aesthetic to strengthen the free spirit is the core of the aesthetic.

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.

지구 표면적의 71%를 차지하고 있는 해양은 평균 수심이 4,000 m, 염분 농도가 35%$_{o}$, 해수의 $90{\sim}95%$의 평균온도가 $5^{\circ}C$ 이하인 특성을 지닌다. 이러한 높은 수압, 고염도, 저온 등 육상에 비해 극한 환경에 속한다 할 수 있는 해양환경에 적응하기 위하여 해양생물은 육상생물과는 다른 특성을 발전시켜왔다. 이러한 육상 생물과는 다른 물질이나 기능을 바이오산업에 이용하려는 추세가 급증하고 있어 해양생물은 생명공학의 주요 자원으로 급부상하고 있다. 그러나 3면이 바다인 우리나라의 좋은 여건에도 불구하고 해양수산부를 중심으로 한 해양바이오 독자기술의 확립과 특화기술개발에 대한 투자는 아직 타부처에 비해 미미한 상황이다. 본고에서는 해양바이오 산업을 미래 첨단 국가기간 산업으로 육성하기 위하여 해양수산부가 추진하고 있는 해양바이오 연구사업의 현황과 신규 대형 장기 연구사업으로 추진하고 있는 마린바이오 21 사업에 대하여 소개하고자 한다.

현대 사회는 정보의 홍수 시대로서, 날로 늘어나는 정보의 바다 속에 검색의 한계도 존재하며 사람들이 원하는 정보를 선별하는 능력이나 방법도 고도화 되어져야 한다. 본 논문에서는 이러한 문제점을 해결하기 위해서 교육용 문서에 적합한 카테고리를 가지고 있는 RSS에 대한 소개와 함께 RSS 리더를 설계하고 구현하고자 한다. RSS 신디케이션 포맷은 누구든지 코멘트, 뉴스 헤드라인, 최신기사에 대한 링크, 설명 그리고 이미지 등을 쉽게 공유할 수 있도록 해준다. 이러한 정보는 웹사이트뿐만 아니라 PDA, 핸드폰, 이메일 등에서도 자유롭게 볼 수 있다. 이러한 RSS 기술은 e-learning에서도 추후 변화를 가져다 줄 것으로 예상된다. 교수설계자가 설계한 학습단위의 완성을 위해 자료를 수집하여 초고와, 원고를 만들기 위해 교정, 교열을 하며, 디자이너를 통해 HTML 페이지를 만들던 기존의 프로세스를 대폭 간소화시켜 줄 수 있기 때문이다.

최근 원도우XP에 대한 기술지원 종료가 사회적 이슈로 대두되고 있다. 우리나라는 다른 나라에 비해 데스크톱 OS 분야에서 원도우 OS를 사용하는 비중이 높은 상황이다. 과거 국산 OS 개발 노력은 있었지만, 원도우 환경의 편리함, 업무환경 등의 동반지원 부족 등으로 원도우 OS 제품을 성공적으로 대체한 사례는 아직까지 없다. 한편, 모바일 OS에서는 바다(Bada), 타이젠(Tizen) 등 상용화 사례가 있다. 윈도우XP 서비스 종료는 특정 솔루션에 대한 의존에서 탈피하기 위한 기회라는 점에서 정부는 오픈소스 기반 OS를 개발하여 행정용 PC에 활용한다는 계획이다. 데스크톱 OS 전환의 선결과제로 OS 자체에 대한 사용자 편리성, 안정성 그리고 보안성이 해결되어야 하며, 관련 기술 생태계가 확보되어야 한다는 지적이다. 본고에서는 먼저 OS 시장의 규모와 국내 시장점유율 현황을 검토하였다. 그리고 찬성론과 신중론 관점에서 윈도우XP 서비스 종료로 불거진 OS 개발 논쟁에 대해 살펴보았다.

A case of distal lower leg replantation, in an elderly patient, was successfully performed after retrieval of the amputated limb from 3 hours of immersion in seawater. Due to the patient's age, bony union was delayed and functional nerve recovery was unsatisfactory. After massive saline irrigation of the amputated part, employing a catheter through the main artery, as well as, prophylactic antibiotics to prevent infection by Aeromonas, there were no postoperative complications. Despite the issue of age, immersion of an amputated part into seawater is not a contraindication of replantation.
