Recently development trends in information technology expand the activity boundaries for human living beyond coastal zones. These rapid changes of paradigm are stimulating scientists and strategists to be encouraged in making adequate model for marine geographic information system (MGIS) and their applications. Coastal zones are places which are affected by many factors, such as water quality, tide, wave, atmosphere, population, industry, etc. Therefore information related to the coast has to be integrated and analyzed for managing it efficiently. GIS-based Ocean Informatics is suited for those purposes and used in the study for establishing and managing coastal geographic and environmental information system. This paper reviews the properties of ocean and coastal spaces, then defines some MGIS related terminologies for clarifying the scope of MGIS boundaries. In this study, coastal geographic information is established by digital geographic information and digital terrain information. Digital coast chart having information on digital chart and map can merge and analyze various coastal information and can be a useful tool for the coastal integrated management.

연안습지로 분류되는 갯벌은 육상과 해양을 연결하는 주요 전이대로서 다양하고도 고유한 생물상을 포함하면서 필수적인 생태적 기능을 수행하고 있다. 우리 인간을 포함하여 주변의 생물들이 누려왔던 갯벌의 생태계서비스 기능과 그것의 긍정적 효과를 유지 또는 강화하기 위해서는 갯벌의 보전이 매우 중요하나 국내의 경우 지금까지 보존보다는 개발이 우세하게 진행되어 왔다. 따라서 본 연구에서는 갯벌매립으로 인한 환경영향을 최소화할 수 있도록 해안개발사업으로 인한 갯벌훼손의 사례를 유형별로 분석하여 이를 토대로 저감방안을 수립하고자 하였다. 지금까지 해안개발사업을 추진하면서 입지선정단계에서 사업대상지가 갯벌로 구성되어 있다는 사실을 중요한 고려사항으로 인식하지 못하여 왔다. 이에 따라 1960년대 이래 우리나라 갯벌 면적의 거의 절반에 해당하는 갯벌이 매립되었고, 개발로 인해 주변 갯벌은 직 간접적으로 훼손되었으며, 모든 계획을 수립한 이후 환경영향평가의 협의단계에서 문제점이 지적되어 사업이 원래의 계획과는 다르게 수정해야 하는 경우도 나타나게 되었다. 이러한 문제점을 해결하기 위해서는 사업을 계획하는 초기단계에서 갯벌 환경에 대한 고려가 우선적으로 이루어져야 한다. 특히 입지선정단계에서 해양환경이 양호하여 다양한 생태계 기능을 수행하는 갯벌 (펄갯벌 및 모래갯벌)을 포함하여 암반 조간대, 사빈, 조하대 잘피숲 및 해중림 지역은 배제하도록 하여야 할 것이다.

The natural ecology of our coastal zone has been well preserved because of the designation of Han-Ryea national sea park. However, recently, it is being threatened by the frequent request of district regulation of national park and relaxation of green belt, etc. And also, with the reclamation of the foreshore by the development of industrial complex and tourism resource cultivation on a large scale, development pressure for natural coast is increasing. For that reason, preservation of the ecology, organized management and investigation is needed for the islands which scenery is beautiful and rare animals and plants inhabit. And also, it is worried that major habitats of migrants are diminishing because of the district regulation of national park, relaxation of green belt zone and construction of coastal streets. Therefore. on the basis of the through environmental impact assessment, only the business which are aimed at the preservation and restoration of the natural coast should be admitted and the act of eroding must be restricted.

A study on the changes of the oceanographical environment caused by Mokpo coastal zone development was carried out. Special emphasis was placed on the clarification of the water level changes and coastal current structure and influence of the environmental factors on the coastal area. In order to understand the structure oceangraphical environemnt, such as water temperature, salinity, suspended solids, pH, dissolved oxygen, chemical oxygen demand, biochemical oxygen demand, distribution of bottom sediment, tide and current were measured. To investigated the structure of tide and current for the future development, a numerical analysis was carried out. In certain zones, it was found to be flooding problems near the lowlying commercial area.

이 연구에서는 단면 수리모형실험을 통해 파의 여러 위상에 따라 단일 및 이중유수실 유공케이슨 방파제의 연직벽에 작용하는 최대 수평파력을 계측하고 그 크기를 서로 비교하였다. 본 실험 자료 분석 결과 이중유수실 케이슨의 유수실 전체 폭이 단일유수실의 폭과 동일한 경우 이중유수실 케이슨에 작용하는 총 수평파력이 평균적으로 9.6% 작은 것으로 나타났다. 이러한 파력 저감 효과는 이중유수실 케이슨 방파제의 유공 전면벽과 무공 후면벽 사이에 위치한 유공 중간벽에서 파 에너지가 소산되기 때문인 것으로 파악되었다.

In this paper, we propose a robust background removal integral projection(BRIP) method which can detect close surface targets in coastal environment for IRST. Row pixels of background region from coastal infrared image show similar response. Thus, the proposed BRIP is calculated after horizontal and vertical background estimations and removals are performed sequentially. Finally, surface large targets can be detected using the results of the BRIP. Experimental results on a set of real infrared image sequence show that the proposed method could fully detect ships in every frame.

The variety of organic and inorganic pollutants are introduced to coastal sediment and making highly contaminated due to rapid development of industralization and economic development. Numerous contaminants are release into marine sediment and it significantly affect marine aquatic environment. In the present study stated the optimize the biostimulant ball (BSB) in coastal sedimentand stabilse the heavy metals present in the sediment. The effective variables like BSB size, distance and month variables on Cu stabilization was determined by using Response surface methodology(RSM). The analysis of variance (ANOVA) and coefficient determination (R2) of Cu reduction 0.9610 and maximum stabilisation was obtained in 3cm ball size and 5.5cm distance and 4 month interval time. This result revealed that the BSB in effective for Cu reduction in coastal sediment.

This study is to set up some models and make plans of the seaside resorts at coastal area in Korea. In order to do this we analyse the characteristics of east, south and west coastal areas of Korean peninsula. And we divide coastal areas into three categories, such as suburban area, fishing village area, and island area, according to their development phases and the distances from nearby big cities. Three types of seaside resort model for three categories of coastal areas are set up. At last we make site plans and images of three types of seaside resort model.

Understanding the flow circulation is of primary importance for studies of marine ecology and Pollution protection etc. However the circulation in coastal area is complicated with various processes and can not be considered as forced only by tides. The coastal area off South China is now playing an important role in economic development in southeast Asia with Hong Kong, Macao, Guangzhou and other cities situated in its central part (Fig. 1).

As wind waves generated in deep water approach nearshore zone, they experience various physical phenomena caused by bathymetric variations, nonlinear interactions among different wave components and interferences with man-made coastal structures. Among these, the bathymetric variations may play a significant role in the change of wave climate. The accurate calculation of reflection and transmission coefficients of incident waves over a bottom topography is indispensible for the proper and economical design of coastal structures. (omitted)
