최근, 우리나라는 소득수준 향상, 교통여건 개선 등으로 여가활동 및 관광형태가 다양화되면서 육지 레저에서 해양 레저 활동이 증가하고 있다. 하지만 이런 여가활동을 수용할 수 있는 기반시설을 구축하고 있지만, 아직도 부족한 실정이다. 또한, 시설 구축 시 도입되는 기자재는 거의 전량을 수입하고 있으며 특히 마리나 구축 시 사용되는 긴장계류장치도 비슷한 상황이다. 따라서 이 논문에서는 에틸렌 프로필렌 고무와 아라미드섬유 등 재료를 이용하여 긴장계류장치를 구성하고 신뢰성 기반 강건 설계를 통해 국내 해양환경에 적합한 제품을 개발하여 해양레저문화 활성화와 산업발전에 이바지할 수 있을 거라고 생각한다.

The costal area where takes up over 32% in domestic teritory is considered as very importantly because it has not only economic facilities such as harbor and an industrial complex but also recreation facilities. Moreover, the tidal flat area has been used as culture ponds and salt farms because this area is occupied by various oceanic species. Also, the tidal flat area has played an important role to purify ocean pollution and maintain an ecosystem. However, the costal ecosystem has seriously threatened by domestic reclamation projects and a large-scale tide embankment during recent 10 years in Korea. This serious problem results in loosing 34%(810$km^2$) of the entire domestic costal area. In this paper, the micro-landform in the tidal flat area, which is called as Garolim bay in Korea, is classified by using Landsat TM images also verified through a filed report. Through the result of this, the tidal flat area is expected to manage efficiently especially through analyzing sediment environment and characteristic of grain size by using satellite images.

We investigated the growth and phosphate uptake of a toxic dinoflagellate, Gymnodinium catenatum, isolated from Yeosuhae Bay, South Korea. A short-term phosphate uptake experiment revealed that its maximum uptake and the half-saturation constant were 1.39 pmol/cell/hr and $2.65{\mu}M$, respectively. In a semicontinuous culture, the maximum specific growth rate and minimum phosphorus cell quota of G. catenatum were 0.39/day and 1.27 pmol/cell, respectively. Thus, G. catenatum is a poor competitor in terms of inorganic nutrient use and is unlikely to form blooms in Yeosuhae Bay.

Recent studies have shown the importance of viruses as potential sources of plankton mortality, which affect primary production and biogeochemical functions of their hosts. Here, we report basic characteristics of a novel virus (Stephanopyxis palmeriana virus: SpalV) that causes lysis of a culture of the diatom S. palmeriana, which was isolated in Jaran Bay, Korea, in August 2008. SpalV is a round-shaped viral particle ~25-30 nm in diameter that propagates in its host's cytoplasm. In addition, it shows species-specific infectivity among the tested diatom species. The burst size and latent period are estimated to be roughly 92 infectious units $cell^{-1}$ and <80 h, respectively.

Longline type aquaculture facilities are being used for scallpop culture in 30 m of water 2.5 km off the coast of Joomoonjin, Kangwon-do. In this paper, the facilities are modeled by the cabele-buoy-weight system, subject to the nonlinear behaviors of the mooring lines and the effects of current. Its static configuration is shown as a solution of 3-D nonlinear static equation and Runge-Kutta $4^{th}$ method is employed.

1-Acetyl-$\beta$-carboline was isolated as an anti-MRSA agent from the fermentation broth of a marine actinomycete isolated from marine sediment. The producing strain was identified to be Streptomyces sp. by phylogenetic analysis of the 16S rRNA gene sequence. The anti-MRSA agent was isolated by bioactivity-guided fractionation of the culture extract by solvent partitioning, ODS open flash chromatography, and purification with a reversed-phase HPLC. Its structure was elucidated by extensive 2D NMR and mass spectral analyses. Combination of 1-acetyl-$\beta$-carboline with ampicillin exhibited synergistic antibacterial activity against MRSA.

As the international society becomes more and more open, the international marine transportation demand is growing. And the growth of international tour demands and the developments of new passenger ship routes make the role of passenger terminals crucial. In this context this study analyzes and compares the terminals of Korea and Japan and defines design criteria for the construction of a passenger terminal. As a result of this study, it is proposed that an urban context, an architectural type and spatial characteristics be taken into account for the construction cf a passenger terminal. The ultimate purpose cf this study is to build a future-oriented international passenger terminal based on the result of this study, which will lead the ocean culture.

해산 copepod는 어류 양식을 위한 초기먹이생물로 가장 이상적인 것으로 알려져 있으며 최근 이들의 대량배양에 관한 연구가 많이 시도되고 있다. 따라서 본 연구는, 기수산 copepod인 Paracyclopina nana의 대량생산을 위해, 실용화 가능한 배양방법개발의 일환으로 rotifer 대체를 위한 P. nana의 nauplius 생산법과 Artemia 대체를 위한 P. nana의 C4-성체 생산법으로 나누어 대량배양을 시도하였다. P. nana의 nauplius 생산 시, 수확된 nauplius는 약 95% 이상이 N1-N2였다. 15일 동안 수확된 nauplius의 일일 평균 생산량은 1, 2차 각각 $6.9{\times}10^6$, $7.2{\times}10^6$였으며, 배양수 내의 암컷과 포란한 암컷의 수는 시간이 경과할수록 약간 감소하는 경향을 보였으나 15일 동안 비교적 일정한 개체수를 유지하는 것으로 나타났다. C4-성체의 생산시, 수확된 copepod의 비율은 C4-수컷, 암컷 및 포란한 암컷이 각각 약 49%, 28% 및 18%였으며 일일 평균 생산량은 1, 2차 각각 $8.2{\times}10^5$, $9.0{\times}10^5$ 개체였다. 결과적으로, P. nana 대량배양 방법에서 nauplius와 C4-성체의 일정한 생산이 가능하였으며 어류의 입 크기에 따라 배양 방법의 선택에 의해 연속적인 먹이 공급이 가능할 것으로 판단된다.

수변공간개발 사례를 중심으로 문화예술을 활용한 도시공간 재생의 의미를 이해해 보고자 한다. 특히 지역문화의 활성화를 핵심적인 의도로 가지는 문화도시전략에서 문화예술의 역할을 해항도시의 수변공간개발에서 문화정책 및 그 실현과정을 통해 고찰한다. 이를 위해 수변공간을 둘러싼 역사적 건축물이나 수변 경관 등 개성적이고 매력 있는 도시경관과 지역자원을 활용하여 문화예술공간 창출을 통한 성공적인 수변공간개발을 진행하고 있는 일본 요코하마를 대상으로 살펴본다. 요코하마는 일본의 '문화예술창조도시' 전략의 일환으로 '창조도시 요코하마'라는 문화정책을 펼치고 있는데, 그 중 공간계획정책이라고 할 수 있는 '내셔널 아트 파크 구상'은 문화예술공간 창출을 통해 수변공간 재생을 실현하고 있다. 이 사업의 기본적 의도와 구체적 실행과정 등을 살펴봄으로써 해항도시의 수변공간개발에서 문화예술이 가지는 역할을 이해하고 수변공간 재생에 있어서 문화정책의 방향성에 대해 검토한다.

This study investigated the productivity and growth of copepods, Sinocalanus tenellus 2 strains, Paracyclopina nana 3 strains, Apocyclops royi 2 strains, Tachidius triangularis 1 strain and Tigriopus sp. 1 strain at different temperatures $(24,\;28\;and\;32^{\circ}C)$ under 15 psu and various salinities (10, 20, 30 psu) at $28^{\circ}C$ for an individual culture. And the mass culture was carried out to evaluate the production of these copepods in the 500 mL vessel. For an individual culture of copepod, survival period of a brood female tended to increase with the decrease of temperature, but was not significantly influenced by salinity. With an increase of temperature and a decrease of salinity, maturation period of nauplii in all species tended to decrease. Total nauglii production from a broodo female at $24^{\circ}C$ was higoher than that from a brood .female at either 28 or $32^{\circ}C$ for S. tenellus and at $32^{\circ}C$ than either 24 or $32^{\circ}C$ for A. royi Haenam stram, but was not influenced by temperature for another copepods. And total nauplii production from a brood female at 10 and 20 psu tended to be higher than that from a brood female at 30 psu, expect for Tigriopus sp. and P. nana Hwajinpo strain. Total nauplii production from a brood female was the highest in Tigriopus sp. (350 nauplii) at $28^{\circ}C$ under 20 psu, followed by A. royi Haenam strain (187 nauplii) at $32^{\circ}C$ under 15 psu and P. nana Hwajinpo strain (152 nauplii) at $24^{\circ}C$ under 10 psu. In the mass culture of each copepod, P. nana was the most productive (26.6 mg dry weight) and this value was two and four times higher than productivity of Tigriopus sp. and A. royi, respectively.
