Japan's new Basic Ocean Law took effect in 20 July 2007. This law contains that 1) calls for the consolidation of eight government offices that previously worked separately on maritime issues; 2) establishes a basic plan for maritime matters, and; 3) creates a comprehensive maritime policy headquarters, run by the Prime Minister. The result is a structure for the integrated promotion of maritime policy. The Minister of Land, Infrastructure and Transport has been appointed to the newly established position of maritime minister. Japan has been in conflict with Korea and China over EEZ and territory, which has caused the country to turn to ocean. If Japan puts more emphasis on sea, it will be on a collision course with neighboring countries such as Korea, China, Russia, and Taiwan. Japan has been at odds with these countries; with Korea over Dokdo islets, with China over the Senkaku Islands and the East China Sea, where gas fields lie, with Taiwan over fishery rights in the East China Sea, with Russia over the Kuril Islands. Korea's position about the establishment of Japan's new Basic Ocean Law is followed: 1) expression of Korea's position in maritime resourcces of east china sea, 2) understand of strategy for maritime resources development and maritime delimitation in China and Japan, 3) a caution for extention of EEZ and maritime activities, 4)effective and comprehensive policy establishment, and strength in R&D, 5) construction of active and responsive system for maritime issues in neighbor country.

통영 연안 양식장 주변 해역에서의 환경특성을 조사하기 위해 2013년 7월부터 12월까지 통영 주변 10개 정점에서 해수와 퇴적물 내의 pH, 용존산소(DO), 용존무기질소(DIN), 용존무기인(DIP), 화학적산소요구량(COD), 산휘발성물질(AVS)에 대해 분석하였다. 양식장 주변 해수의 수질항목들은 계절별에 따른 경향성을 나타내었으며, 퇴적물 속 COD와 AVS를 분석한 결과 수질항목과는 달리 어장으로부터의 거리에 따라 농도가 감소하는 경향을 나타내었다. 이는 본 조사지역에서 반폐쇄성 만에 위치하고 있는 어장 활동에 의해 오염된 유기퇴적물이 비교적 빠른 유속으로 인해 주변 해역으로 분산된 것으로 예측된다.

With the efforts to development of renewable energy technologies, and increasing awareness to environmental issues, the usage of wood pallets has been increasing every year since the introduction of wood pallet technology to the domestic market. until 2009, majority usage of pellet boiler was in the residential houses. In an effort to increase the distribution of wood pellet boiler to cultivation facilities with high usage of fuels, The Ministry of Agriculture and Forestry has launched a distribution project of wood pellet boiler for fuel usage as a part of the agricultural and fishery energy efficiency projects. Although only small number of farms with a heat-culturing facility have replaced from conventional boiler to pellet boiler. Although part of reason for low usage of pallet boiler is lack of understanding and information of it, the main reasons are high initial cost and uncertainty of its cost efficiency. Also, most people from agricultural industry don't realize it's significance in terms of environmental benefit due to lack of understanding in 'resource circulation' and 'adopting to climate change'. In this study, first, we did a cost-efficiency analysis of the farm which uses a diesel boiler to grow cucumber, tomato, paprika. Then we replaced the diesel boiler to a pallet boiler and measured its cost-efficiency again. By comparing the cost-efficiency of the diesel boiler with the pellet boiler, we analyzed the economic viability of pellet boiler. Then we analyzed viability of pallet boiler usage in terms of 'resource circulation' and 'adopting to climate change'. As a result of our analysis, we have found out that under the current system of government support, the energy usage varies depends of the types crops grown and the higher the energy use, the more cost efficient it is to use the pallet boiler. Also, it is economically viable to use the pallet boiler in terms of 'resource circulation' and 'adopting to climate change'.

The economic efficiency for fishery products can be related to their freshness and the quality. In order to freshly storage the product, freezing equipment system is necessary for fishing vessels. For this purpose, the horizontal plate freezer (HPF) is mostly used. In this research, our major objective is to improve the freezing performance of the HPF. Therefore, it is important to analyse the relationship between the shape of channels and the cooling temperature of the HPF. In order to save calculation time while checking the trend analysis between shape and performance, we used scaled models, and evaluate the cooling temperature of full scale model based on trend analysis results. The produced HPF in domestic was used, and the same operating conditions are considered. Based on this paper, the future research will be a comparison and verification through the experiments.

This study examines the effects of consumer beliefs for food certifications on the behavioral intentions and the behavioral intention biases to purchase the certified seafoods by a subjective probability model which is on the basis of the mathematical probability model and the covariance model. The food certifications used on this study are 'Organic foods', 'Traceability system of food products' and. 'HACCP'. The representative foods of fishery products on this study is seasoned laver. The current study showed the following results. First, consumers have more than two different beliefs each for all certifications which are the subjects of this study. The beliefs of the certifications have an impact on the consumers when they consider to buy the certified seafood products. Second, consumers try to persuade by themselves to ensure that their particular belief about the certification could lead to a purchase the seafood products. Consumer beliefs of the "environmentally friendly production" on the organic foods certification is an important factor as much as the "guarantee of food safety" belief making a positive purchasing behavior intentions(PBI) bias for the organic seafood products. Consumers also have a positive PBI bias for certified seafood products in all certifications as long as a certification is considered to "guarantee the transparency of the food distribution process" as its belief. 'Traceability system' was the only one which didn't generate a positive PBI bias from the belief of "guarantee of food safety" out of three certifications.

The sea of north-east Asia is biologically interrelated and one country's mishap in the management of fisheries could have a critical effect upon the other. Accordingly under the TAC system adopted by all the countries of Korea, Japan and China, the mismanagement o( trans-boundary fish stocks under the provisional fisheries agreement prior to the delimitation of EEZ could lead to the irrevocable depletion of fisheries resources in case of absence of close cooperation among the countries concerned. To tackle the problems above, it is necessary, from a short term perspective, to promote the combined efforts to do researches on fisheries resources, find ways to improve the transparency of fisheries management, adjust the fisheries management regulations of each country, standardize fishing gears and methods, and exchange fisheries-related statistics and data for socio-economic analysis and strengthen joint research activities for the mutual benefits. From a longer term prospective, regional fisheries organization need to be set up to oversee the whole area of north-east Asian sea. The organization as such could play a role in adjusting the conflicting interests of Korea, Japan and China, and efficiently manage the fisheries resources, which is complex and challenging in nature. In addition, unlike China, the historical fisheries relationship between Korea and Japan, spirit of reciprocity and the Article 62 of the United Nations Convention On the Law Of Sea need to be taken into account when seeking for fisheries cooperation between the two countries through the international specialization. In other words, the data obtained through the joint researches on the fisheries resources for the specific ocean along with such factors as capital, labor, fisheries technology and consumption of fish products could be used to assign the specific sector of fisheries to the country who has a comparative advantage, thus achieving the mutually benefiting results Up to the present, concerted efforts by Korea, Japan and China on the fisheries cooperation have been consistently made, but the results have yet to be materialized, It is also beyond doubt that governmental consultations among the countries should be made on a consistent basis, but non-governmental organizations' exchanges and related joint researches will more likely help bring about the desired fruition in a shorter time.

국립수산진흥원이 관측한 염분자료를 분석하여 여름철 남해의 저염화 현상을 규명하였다. 6월과 8월에 남해 전 수심의 저염화는 강수량과 강물의 유입으로는 설명될 수 없고, 주위 해역 중 유일하게 저염수가 존재하는 제주해협 서편 해역 저염수의 유입으로만 설명이 가능하다. 염보존 Box 모델의 결과에 의하면, 대한해협 서수도의 수송량을 1.4-2.0$\times$$10^{6}$ ㎥/sec이라고 할 때, 이 수송량의 31-36% 정도인 0.5-0.6$\times$$10^{6}$ ㎥/sec(평균유속은 10-13cm/sec)의 수송량이 제주해협을 경유하여 남해로 유입되고, 나머지는 제주도와 대마도 사이로 유입된다.

1980년 6월과 1981년 8월 제주해협과 황해의 동남 해역에서 8-16해리 간격으로 수 온-염분의 정밀 관측을 실시한 결과, 대양성의 고온 고염수가 제주도 서쪽연안 20 km 이내에 존재함을 발견하였다. 동시에 제주도 주변 해역의 표층에 나타나는 저염분 골 이 양자강퇴 해역의 저염분수에서 기원함이 확인되었다. 이 골에 의해 고온 고염수는 황해 표층수와 분리되며, 저층에서는 황해의 저층냉수와 전선을 이루고 있다. 황해 냉 수는 양자강퇴의 70 m 수심을 따라 동지나해를 향하여 남하하며, 또한 부분적으로 제주 해협의 북쪽 단면에도 나타나 남해로 유입 가능성이 크다. 이러한 복잡한 수계구조와 공간적 분포는 황해난류가 한국 서해안을 향하여 북상한다는 기존 학설(Uda, 1934)과 는 일치하지 않으며, 지속적인 조밀한 정선관측을 제주도 주변 해역에서 순서하여 해 류 구조의 시·공간적 변동상을 파악하여야 한다.

새우에 일정량의 식염, 아질산염, 질산염 및 아스코르브산을 첨가하여 숙성시키면서, NA생성에 미치는 영향에 대해 조사한 결과는 다음과 같다. pH는 담금직후 8.1에서 숙성 110일 후 6.5로 산성화되었다. TMAO 질소는 숙성중 감소한 반면, TMA 및 DMA질소는 증가하였다. 아질산염 첨가구는 숙성중 NDMA함량이 증가하였고, 아스코르브 산첨가구는 NDMA생성이 억제되었다. 모델계실험 결과, 새우젓의 니트로소화 최적 pH는 3.5이었고, 아스코르브산은 NDMA생성을 크게 억제시킨 반면 thiocyanate는 촉진시켰다. 본 실험 결과, 새우젓 자체에는 NDMA가 거의 검출되지 않았으나, 질산염이나 아질산염의 함량이 많은 물질과 함께 섭취된다면 위내에서 NDMA가 생성될 가능성이 충분한 것으로 판단되었다.
