  • 가축 사육시설에서 배출되는 축산폐수는 도시하수와 달리 발생량에 비해 오염부하량이 대단히 크므로 수질오염의 주범일 뿐만 아니라 처리에도 어려움이 많아 축산폐수를 수거하여 전문적으로 처리하는 공동처리장에서도 현재 만족 할만한 처리효과를 기대하기 힘든 처지에 있다. (중략)

  • Methodology and application of Strategic Environmental Assessment (SEA) for policies, plans, and programs are still new approach in Vietnam. With a support from Vietnam-Swedish Project (SEMLA) and Ministry of Natural Resources and Environment (MONRE), SEA for the Tonkin Gulf Coastal Economic Belt Development Plan was conducted in 2008. Lessons obtained from this SEA may contribute to improving methods and practicing SEAs for regional development. The main lessons summarized in this paper are: (i) close cooperation between the planning and environmental teams from the beginning phase of a master plan; (ii) SEA should focus not only on impacts to the natural environment but also on main issues of socio-economic aspects; (iii) approaches and methods used in SEA should be appropriate to properly predict the impacts at regional-levels and cumulative impacts; (iv) a good SEA study may be achieved when detailed data on the environment and socio-economy of the study area are available and have active engagement of stakeholders, including project affected sectors, ecologists, planners, policy makers, etc. This paper is useful for whom, those work in SEA in regional development.

  • The main objective of this paper is to investigate the potential utility of multisensor remotely sensed data for improved coastal wetland mapping. Five data fusion models, three algebraic models (Multiplicative (MT), Brovey (BT) and Wavelet transform (WT)) and two spectral domain models (Principals component transform (PCT) and Intensity-Hue-Saturation (IHS)) were implemented and tested over the multisensor data. The fused images were then compared based on visual and statistical approaches. The results show that the wavelet transform provides greater flexibility for combining optical data sets and has good potential for preserving the spatial and spectral content of the original images . However, this model yields poor information when combining optical and microwave data. Brovey transform is more reliable for fusing optical and microwave image data and yields improved information about different wetland features of the coastal zone.

  • Traffic density has increased recently in Korean waters due to an expansion of the sea trade and the development of coastal fisheries. The enlargement of the coastal industrial belts and the development of coastal inslands further increases marine traffic. The rapid increase of marine traffic has often resulted in marine casualties with the attendant loss of life, damage to property, and marine pollution. Especially, tanker casualties may destroyed the food web and an untold amount of ocean resources. Un regard to the potential of tanker spills in Korean waters, systematic research in this field is lacking. In this paper, the data relating to a total of 261 tanker casualties in Korean waters has been compiled and statistically anlaysed. The result of this study describes the general trend of marine casualties in Korean waters, and describes the casualtiy database, from which their causes and consequences are derived and this results in the determination of the causal relationships connected to tanker casualties, and quantifies the effective level of causal factorsin Korean waters.

  • This study estimated the technical efficiency of coastal composite fishery in Korea by using the data envelopment analysis (DEA) and the stochastic frontier analysis (SFA) methods, and the results on the respective method were compared. In the DEA method, the constant returns to scale (CRS) and the variable returns to scale (VRS) output-oriented DEA models were separated and technical efficiencies were estimated, respectively. The average estimated value of technical efficiency by the SFA method (0.633) was found to be lower than that by the VRS-DEA method (0.738), while it was higher than that by the CRS-DEA method (0.479). It was found that strong correlation exists between the SFA method and the VRS-DEA method. The method which can utilize both methods in mutually complementing way for the estimation of technical efficiency was also considered.

  • The increase in seaborne cargoes has made our coastal traffic congested, and future coastal traffic is also expected to increase considerably as result of our economic development and high dependence on foreign trade. This increased traffic may be a cause of serious sea pollution as well as greater number of sea accidents. In view of this problem the introduction of VTMS along on our coast is required, following careful study of a large number of foreign systems. This paper analyzes the actual condition of 132 VTMSs in the world from the view point of management method authority of VTMS, coverage and characteristics of system. And this results provide helpful information for the development of VTMS in the future and for the implementation of VTMS in our coastal waterway.
