Planting models for restoration forest on the seaside have been demanded because coastal reclaimed land has increased for habitation sites, industrial complexes and new towns on the west seaside of Korea. The planting models have to consider endurance for bad environmental conditions in order to make a role to protect the urban space against the extreme seaside environment. The dominant species, relative impotance value, individuals and species number were analysed in natural forests that were exposed to extreme seaside conditions in Deokjeok island and Younghung island, Incheon. The native species such as Pinus thunbergii and Pinus densiflora, which survive on the seaside, were mainly recommended because the coastal reclaimed land had extreme environmental conditions. Stable vegetation structures could be made by multi-layer planing by using these species. A diverse vegetation community could be made according to these planting models. The maritime forests made by these planting models might be more effective for environmental adaptation and a windbreak forest than alone tree, and the young trees below 3m height could easily adapt to these conditions.

최근에까지 대형구조물이 해양공간이용의 목적으로 외해공항 및 해양터미날로 건설되어 왔다 그러나 때로는 이와같은 큰 규모의 구조물은 파량에 대해 현저한 벽으로 작용하게 되고 해안에 심각한 침식현상을 야기하게 된다 본 연구는 해안선으로부터 각기 다른 거리에 외해구조물을 건설할 때에 해저지형변화를 다룬 것으로 일련의 3차원 이동상실험으로 상세히 조사하였다 또한 해빈류와 외해구조물 배후의 국소침식과의 관계를 분명하게 하기 위하여 수리모델실험과 같은 규격으로 Boussinesq방정식 모델로 해빈류를 계산하고 비교하였다.

The road construction near the existing lighter's wharf has completed but the lighter's wharf has been still unavailable and neglected. Therefore, the site needs the urgent measures to clean up and properly take advantage of the lighter's wharf. This study sought to improve the regional amenities and revitalize the coastal environment by creating an environment-friendly waterfront park utilizing features of the existing lighter's wharf as part of improvement measures. In addition, surveys were conducted to develop an waterfront park capable of effectively using the land and improving the cleanliness and safety of the coastal scenic beauty, leading to various meaningful opinions on the residents' awareness of the potential park site, the facilities necessary for the park, the development directions of the park and the timing of park development. If an waterfront park is created through the residents' participation, It can share a sustainable utility value of the coastal area. Therefore, this will result in boosting the connection with redevelopment plan for the North Port, along with improving the quality of the residents' life, strengthening Busan's status as a maritime tourism city.

현대 사회에서의 항만공간은 과거와는 달리 단순히 항구로써의 기능만을 위한 공간이 아닌 주거, 레저, 관광 등 다양한 기능이 복합화 되고 있다. 그에 따라 더욱 많은 사람들이 밀집하는 공간으로 변모해 가고 있다. 반면 항만 공간은 지형적, 환경적 특성 상 재해에 취약한 공간이기도 하다. 하지만 아직까지 국내에서는 방재 도시계획이 명확히 자리 잡고 있는 실정이 아니다. 따라서 항만공간의 특성을 감안한 방재 도시계획을 강화하고, 이를 통해 안전성을 확보할 필요가 있다.

Tsunami disaster caused great damages and very large victims especially when occurs in urban area along coastal region. Therefore information of evacuation in a map is very important for disaster preparedness in order to minimize the number of victims in affected area. Here, information generated from remote sensing satellite data (SPOT 5 and DEM) and secondary data (administration boundary and field survey data) are used to simulate evacuation route and to produce a map for Padang City. Vulnerability and evacuation areas are determined based on DEM. Landuse/landcover, accessibility areas, infrastructure and landmark are extracted from SPOT 5 data. All the data obtained from remote sensing and secondary data are integrated using geospatial modelling to determine evacuation routes. Finally the simulation of evacuation route in Padang City for tsunami preparedness is provided based on the parameters derived from remote sensing data such as distances from shelters, save zones, city's landmarks and the local community experiences how they can survive with the disaster.

Oceanic architecture means architectural space created by directly or indirectly using the features of the ocean in the design. A range of marine structure for residential, leisure, cultural, and industrial uses has been and will be created by adopting these features in spatial composition, program, function, and form. This is a clearly distinct category of architecture which can produce unique and creative environments for man's living. Here this kind of architecture is called oceanic architecture. Nowadays the demand for ocean space is increasing and in the near future the law of oceanic architecture will be established by the government. Even with the present trend in design practice, few academic researches on the new architecture have been executed from an architectural design viewpoint. Accordingly, this study aims to examine the design aspects of oceanic architecture. In this paper firstly the design characteristics and contents of oceanic architecture are dealt. And then the concept architecture is defined on the basis of design characteristics.

심해 파랑변형으로부터 형성된 Dirichlet 경계치 문제를 free space Green함수를 써서 경계적 분방정식으로 바꾸었으며 이 적분방정식을 Cubic spline 요소법을 사용하여 차분한 수치모델이 제시되었다. 유도된 제 1종 Fredholm적분방정식의 수치계산시 안정도를 높이기 위한 Hsiao와 MacCamy(1973) 방법이 사용되었다. 수치계산 결과의 검증을 위해 엄밀해가 존재하는 두 경우를 택하여 비교하였고, 본 모델의 높은 정밀도가 입증되었다.

Retrieval of ocean color information from Multispectral Camera (MSC) on KOMPSAT-2 was investigated to study and characterize small-scale biophysical features in the coastal oceans. Prior to the derivation of such information from space-acquired ocean color imageries, the atmospheric effects largely from path and the air-sea interface should be removed from the total signal recorded at the top of the atmosphere (T$_{TOA}$). In this study, the 'path-extraction' is introduced and demonstrated on the TM and SeaWiFS imageries of highly turbid coastal waters of Korea. The algorithms for retrieval of ocean color information were explored from the remote reflectance (R$_{rs}$) in the visible wavebands of MSC. The determination of coefficient (R$^{2}$) for log-transformed data [ N = 500] was 0.90. Similarly, the R$^{2}$ value for log-transformed data [ N = 500] was found to be 0.93.

This study is aimed to compare stock assessment models depending on how the models fit to observed data. Process-error model, Observation-error model, and Bayesian state-space model for the Korean Western coast fisheries were applied for comparison. Analytical results show that there is the least error between the estimated CPUE and the observed CPUE with the Bayesian state-space model; consequently, results of the Bayesian state-space model are the most reliable. According to the Bayesian State-space model, potential yield of fishery resources in the West Sea of Korea is estimated to be 231,949 tons per year. However, the results show that the fishery resources of West Sea have been decreasing since 1967. In addition, the amounts of stock in 2013 are assessed to be only 36% of the stock biomass at MSY level. Therefore, policy efforts are needed to recover the fishery resources of West Sea of Korea.
