The negative factors of fishery in environmental aspect of view are Greenhouse gas emission problems by high usage of fossil fuel, destruction of underwater ecosystem by bottom trawls, reduction of resources by fishing and damage of ecosystem diversity. Especially, the Greenhouse gas emission from fisheries is an important issue due to Canc$\acute{u}$n meeting, Mexico in 1992 and Kyoto protocol in 2005. However, the investigation on the GHG emissions from Korean fisheries did not much carry out. Therefore, the quantitative analysis of GHG emissions from Korean fishery industry is needed as a first step to find a relevant way to reduce GHG emissions from fisheries. The purpose of this research is to investigate which degree of GHG emitted from fishery. Here, we calculated the GHG emission from Korean bottom pair trawl fishery using the LCA (Life Cycle Assessment) method. The system boundary and input parameters for each process level are defined for LCA analysis. The fuel use coefficient of the fishery is also calculated. The GHG emissions from the representative fishes caught by bottom pair trawl will be dealt with. Furthermore, the GHG emissions for the edible weight of fishes are calculated with consideration to the different consuming areas and slaughtering process also. The results will be helpful to understand the circumstances of GHG emissions from Korean fisheries.

The concern on the greenhouse gas emissions is increasing globally. Especially, the greenhouse gas emission from fisheries is an important issue due to Cancun Agreements Mexico in 1992 and the Kyoto protocol in 2005. Furthermore, the Korean government has a plan to reduce the GHG emissions as 5.2% compared to the BAU in fisheries until 2020. However, the investigation on the GHG emissions from Korean fisheries has not been executed much. Therefore, the quantitative analysis of GHG emissions from Korean fishery industry is needed as the first step to find a relevant way to reduce GHG emissions from fisheries. The purpose of this research is to investigate which degree of GHG emitted from the major coastal fisheries such as coastal gillnet fishery, coastal dual purpose fishery, coastal pots fishery and coastal small scale stow net fishery. Here, we calculated the GHG emission from the fisheries using the LCA (Life Cycle Assessment) method. The system boundary and input parameters for each process level are defined for LCA analysis. The fuel use coefficients of the fisheries are also calculated according to the fuel type. The GHG emissions from sea activities by the fisheries will be dealt with. Furthermore, the GHG emissions for the unit weight of fishes are also calculated with consideration to the different consuming areas. The results will be helpful to understand the circumstances of GHG emissions from Korean fisheries.

The global warming related to GHG (greenhouse gases) emissions from industries is a major issue globally. Furthermore, GHG emissions from the fishery industries also represent an important issue, as indicated by "The Code of Conduct for Responsible Fisheries" at the Cancun, Mexico, meeting in 1992 and by the Kyoto protocol in 2005. Korea pronounced itself to be a voluntary exclusion management country at the 16th IPCC at Cancun, Mexico, in 2010. However, few analyses of GHG emissions from Korean fisheries have been performed. Therefore, a quantitative analysis of GHG emissions from the major Korean fisheries is needed before guidelines for reducing GHG emissions from the fishing industry can be established. The aim of this study was to assess the present GHG emissions from the Korean Purse seine fishery using the LCA (life cycle assessment) method. The system boundary and allocation method were defined for the LCA analysis. The fuel consumption factor of the purse seine fishery was also calculated. The GHG emissions for the edible fish were evaluated by determining the weights of whole fish and gutted fish. Finally, the GHG emissions required to produce 1kg of whole fish and 1kg of edible fish were deduced. The results will help determine the GHG emissions from the fishery. They will also be helpful to stakeholders and the government in understanding the circumstances involved in GHG emissions from the fishing industry.

변전기기의 전력손실은 전력계 전체 중에서는 얼마 안되는 양으로, 그 전력손실에 관련되는 온실효과가스 배출의 비율은 비교적 적다고 할 수 있다. 그러나 일본 전체의 온실효과가스 배출량이 증가추세에 있음을 고려하면, 변전기기에 대해서도 꾸준한 개선노력이 필요하다. 변전기기에 대한 당초부터의 제품개발 방침은 소형화(小型化)$\cdot$간소화(簡素化)이며, 주로 설치환경의 배려(配慮)와 경제성 추구를 목적으로 한 것이므로, 온난화(溫暖化)의 영향을 의식하게 된 것은 지난 몇 년 동안의 일이다. 이들의 제품개발 방침에 의거하여 제품 제작에 따른 환경부하(環境負荷)에 대하여 상대(相對) 비교는 할 수 있으나, 라이프사이클을 고려한 경우에는 운용과 제작시의 환경부하 합계가 지금까지에 대하여 경감(輕減)되었는지를 추정하기가 곤란하다는 문제도 있다. 그래서 제품의 라이프사이클 전체를 통하여 환경에 미치는 부하의 크기를 수치화(數値化)하여 평가하는 것이 필요하게 된다. 라이프사이클 어세스먼트(LCA, Life Cycle Assessment)는 이러한 관점에서 개발된 틀로서 데이터를 취득하는데 많은 시간이 걸리지만, 용도에 따라서는 간편한 방법을 선택하거나 소형화$\cdot$간소화쪽으로 방향을 좁혀 LCA로 상세하게 평가하는 구성도 할 수 있다. 그 최대의 효과는 환경부하를 정량화(定量化)할 수 있는 것이며, 아울러 환경부하의 가일층의 저감이 가능하다는 것을 생각할 수 있다. 또한 LCA사례에서, 제품개발방침인 소형화$\cdot$간소화가 환경부하 저감에 합치하며, 이 방침이 유효하다는 것을 확인하였다.

Corrosion behaviour of water intake gate steel structures with different protective measures was investigated. Five material alternatives were taken for investigation, including: imported and recycled stainless steel, carbon steel with hot zinc spraying, painting and composite coatings. Results of corrosion rate for carbon steel, SUS 304, hot zinc spray coats in three water systems of Mekong river basin (saline, blackish and fresh) were also presented. Corrosion rate of carbon steel decreased with decreasing salinity in the investigated water environments. Meanwhile, these values for zinc coated steel, behaved by another way. Environmental data for these systems were filed and discussed in relation with corrosion characteristics. Method of Life Cycle Assessment (LCA) was applied in materials selection for water intake gate construction. From point of Life Cycle Cost (LCA) the following ranking was obtained: Zinc sprayed steel < Recycled stainless steel < Composite coated steel < Painting steel < SUS 304 From investigated results, hot zinc spray coating has been applied as protective measure for steel structures of water intake systems in Mekong river basin.

지구 온난화의 주범인 온실가스 배출량을 규제하고자 하는 전 세계적인 기조에 따라 건설 분야에서도 이와 관련하여 다양한 노력이 시도되고 있다. 그 일례로 LCA (Life cycle Assessment) 방법론 도입을 통해 $CO_2$ 배출량을 정량적으로 측정하려는 연구가 활발하게 수행되고 있다. 그러나 일반 제조업에서 수행되고 있는 기존의 LCA 방법론은 다양한 자재의 투입과 복잡한 생산구조를 가지고 있는 건설업에 활용되기에는 많은 한계가 있다. 이에 본 연구는 보다 정확하고 세분화된 환경영향 평가를 도출할 수 있도록, 기존 LCA 방법론에 ABC원가관리방식을 도입한 Activity-based LCA 모델을 제안하였다. 이를 기반으로 대표적 온실가스인 $CO_2$의 주요 배출 Activity와 각각 배출량에 대한 정확한 예측이 가능하도록 하는 모델을 제시하였으며, 실제 시공 중인 건물의 커튼월 시스템 공정을 대상으로 하여 그 유용성을 검증하였다.
