In this study, we aimed to build the basic calculation model for linkage effects of fishery industry among Korea, China and Japan. For the calculation, we reconstructed the asian international input-output table, and on the basis of the reconstructed table, we made some analyses on the inter-relations among 3 nations focusing fishery industry. As the results, some positive backward linkage offsets of the fishery industries were found among 3 nations, and especially, production inducing effect of Chinese fishery industry to Japanese supplier was remarkable.

This study focuses on the off-shore trawl fishery, specifically on its restructuring and new regulations governing its operation since the 1990s. This fishery has an important role in terms of fishing capacity and production amount and is dependent on close diplomatic relations with adjacent fishing countries. The off-shore trawl fishery has been shrinking since the 1990s. In addition to a decrease in stock and an increase in imports, there are vessel buyback programs and a decrease in fishing grounds related to a tri-lateral agreement among Korea, China and Japan which have sped up the shrinking of the fishery. In this processing, costs exceed the increase of revenue. Excess investments in fishing gear and salary for crews have lowered profits in this fishery. Considering the above, the off-shore otter trawl fishery should stop increases in production and restructure the fishery by coordinating fishing gear restrictions and fishing areas, and down-sizing management capacity.

The main purpose of this study is to explain fishery relation in the seas surrounding Korea and how the Prisoner's Dilemma (PD), within game theory is applied to the region and suggest possible co-operative approaches in the region. The seas surrounding Korea are very productive fishing grounds with abundant fisheries resources because of the favourable marine environment, including its geographical features and physical oceanography. Nevertheless, Fishery relations among the coastal states in the region have been historically characterized by conflict rather than co-operation. Based on the PD game where there is always an incentive to do better by not co-operating, in order to ensure a share of the short-run benefits, fishing countries in the region have so far pursued the non-co-operative strategy of 'don't fish responsibly' rather than the co-operative strategy of 'fish responsibly'. Considering rapidly deteriorating situations in terms of fishery resources, regional co-operation among coastal states is urgently required to eliminate overfishing and increase fish stocks to sustainable levels. The West Sea/East China Sea and the East Sea, semi-enclosed seas, have unitary ecosystems, and many migratory fish species are shared between coastal states. Therefore, one countries' efforts alone cannot effectively manage and conserve the fishery resources and close co-operation among coastal states is required. The 1982 UN Convention and other international instruments emphasize the role of RFOs in managing and conserving capture fisheries and encourage states to establish Regional Fishery organizations (RFOs) or strengthen existing RFOs to facilitate conservation and management for fish stocks. Therefore, an international regime is worthy of serious consideration in that it provides fundamental advantages for the conservation of fish stocks for the fishery characteristic of the region.

This study is to focus on the status of implementation of bilateral-fishery order based on the Korea-China fisheries agreement and aims to improve fisheries relationship between two countries. Korea-China Fisheries Agreement entered into force in 2001, and serves as a basic framework of the bilateral fisheries order. However, the fishing order between Korea and China has the following limitations. First, it is standstill of joint response for a practical resource management. Second, there are still gaps between the quotas of mutual accord fishing and fishing operation work performance. Third, China's illegal fishing is taking place consistently. Fourth, the effective cooperation between two countries in fisheries is not carried out. Finally, the Korea has faced difficult situations to adhere to a balanced position in the fishery negotiations due to conflicting positions on China and Japan. In order to solve these problems, the fishing order between Korea and China will be able to maintain the competitiveness of Korean fishery sector by reinforcing Korea's fishing sovereignty, Korea and China, based on trust and cooperation, will make efforts to improve bilateral fisheries relations to maximize mutual benefit in fishery sector. Specifically, first, the two countries should strengthen the resources management based on the scientific research and the improvement of imbalance of the mutual agreed fishing in EEZ. Second, Korea has to achieve our targeted performance of fishing operation and establish a joint resources management system between two countries in the provisional measure zone. Third, Korea should implement to collect fisheries information about China fishing vessels which are operating in the EEZ of Korea. Finally, Korea and China should be building up effective governance framework for the establishment of fishing order.

With the major changes in fisheries management brought about by technological, politico -legal, and economic and biological development, new problems have emerged in the fisheries sector of the European Community countries. In 1986, the entry of Spain and Portugal to the European Community made the Community the third biggest producer of fishery products in the world. It also had considerable impact on the Common Fisheries Policy (CFP) due to their fishing fleets. This article examines the complexity of establishing the Common Fisheries Policy in the European Community, while underlining the value of such an approach. It reviews four main areas of the common fisheries policy : access to waters and the conservation and management of stocks ; organization of the market ; structural changes and research, and international relations. It also discusses the specific fisheries problems to which the approach of CAP has been applied. It is argued that the fishery resource policy was the most trublesome to put into practice. It is the forum for such thorny questions as total allowable catch (TAC) and the sharing out of TAC between member states. It is shown that there are many things to be tackled in the CAP for the deeper integration in the fisheries sector. The author concludes by suggesting that the Common Fisheries Policy would be a suitable example to which Republic of Korea could refer in concluding reciprocal fisheries agreements with other countries and making the cooperative fisheries policy with North Korea.

This study aims to evaluate the status of implementation of bilateral-fishery order since the Korea-Japan Fisheries Agreement came into effect in 1999 in order to improve fisheries relationships between two countries. The agreement regulates bilateral-fishery order by the principle of the EEZ regime and mutual benefits among countries. (e.g. the mutual agreed fishing in EEZ and cooperation for resource management). However, the Korea-Japan Fisheries Agreement has some limitations such as reducing quotas of the mutual agreed fishing in EEZ, strengthening Japanese fisheries regulation, insufficient cooperation for fisheries management and joint countermeasures. In order to improve fisheries relationships between the two countries, it is imperative to rebalance quotas for the mutual agreed fishing in EEZ, to establish effective resource management systems in the Intermediate zone, to invigorate fisheries cooperation in the private sector, and to introduce new management systems by species over the all waters around East Asia. To accomplish such measures, it is necessary for Korean and Japanese governments to improve fisheries relationships based on trust and cooperation, achieving a win-win situation. Additionally, it is required to incorporate fisheries management among Korea, China, and Japan.

For the analysis of geothermal energy utilization in agriculture the relations between soil temperature and geographical variables such as latitude longitude and sea level in Korea were analyzed and the regression equations were suggested among them. The measured soil temperature data for four years in eighteen cities were used to get the soil temperature fitting equation depending on the soil depth and the time of year in each city. The mean correlation coefficient for those data fitting was 0.980. the correlation coefficient of regression analysis for the mean soil temperature($T_{m}$) on the geographical variables such as latitude longitude and height above sea level was 0.958 and those for soil surface temperature amplitude(Tss) and phase constant(tp) were 0.889, 0.835, respectively. The relation between the apparent thermal diffusivity of the soil and the three geographical variables was not significant. The regression equations for the mean soil temperature($T_{m}$) soil surface temperature amplitude(Tss) and phase constant(tp) adopting latitude($X_{1}$) longitude($X_2$) height above sea level($X_3$) were as follows : $T_{m}$=50.049 - $0.849X_1$-$0.03131X_2$-$0.00622X_3$Tss=-6.970 +$0.584X_1$+$0.00530X_2$-$0.00214X_3$tp=70.353 - $1.404X_1$+ $0.02098X_2$+ $0.00312X_3$

This research examined the transformations of the fisheries relations between Japan and Russia since the establishment of the Exclusive Economic Zone (EEZ) system. The author reviewed the transformations with investigation on mutual fishing access to EEZ including salmon & trout catches. The Japan-Russia fisheries relations have evolved through multiple developmental stages, which include mutual fishing access to EEZ, the reductions of a fishing quota to balance catches of the nations, provision of financial and technical support, and a payment system of EEZ fishing access fee. The Japanese salmon industry also has done similar practices, continuing to catch salmon and trout in the Russian EEZ. Additionally, Japan and Russia have attempted to develop joint fisheries projects and to assure fishing operation safety around Kuril Islands. The case of Japan-Russia mutual fishing access shows that a country that has authority over crucial fisheries resources tends to establish specific conditions of mutual fishing access so that it maximizes its national interest. Thus, this case gives us implication what could be future directions of Korea-China-Japan multinational fishing access. The principle of same number of fishing vessels and quantities of catches has worked in existing mutual fishing access to EEZ among Korea, China, and Japan. However, it is expected that a nation that is endowed with abundant fisheries resources would limit counterpart's fishing access to its EEZ. Therefore, Korean fisheries administration should prepare for all possible situations like a dramatic cut in fishing quota and the termination of fishing access. International fisheries cooperation and payment of fishing access could be viable options for such a situation.

This study aimed to analyze the relationship between catch amount and market price of sandfish for improvement of fishing revenues and effective fisheries management. By estimating the sandfish price function by fishery, the study tried to investigate changes of prices by catch amount as well as changes of fishing revenues by catch amount and price. Results showed that time series data on catch and price were estimated to be non-stationary from unit root tests, but long-term equilibrium relations between catch amount and price were found from a cointegration analysis. Results of regression analyses indicated that the catch amount would have negative impacts on prices of sandfish in both coastal gillnet and danish seine fisheries.

Since the middle of the 70s, the countries with the marine resources declared the exclusive water zone of two hundred miles. As a result, our country lacked many foreign fishing grounds. This awakened our perception of fishing grounds. The fishing ground is an important factor in the economical effectiveness of fisheries. The fishing ground must have the following basic conditions. 1. It must be the place the fishery resources inhabit and wander. 2. Their catching or aquaculturing must be possible by the technical methods. 3. It must have economic worth in the management. The fishing ground that achieves the above basic conditions is affected by the following factors. This is the factor of the fishing ground location. A. Natural factor 1). Suitable climate 2).Abundant resources 3). Good quality of the sea-bottom 4). Not to be pollutted area B, Economic factor 1). Be adjacent to fishing port and fisheries market 2). Good working conditions 3). Be abundant of economical resources C. Social factor 1). Be possible to work legally 2). Be permitted in the political relations 3). Be acquainted with the customs of foreign countries The fishing ground location is mainly affected by the natural factor of the above factors. The abundance of resources depends on the natural resources. The resources in the fishing ground have the cycle of developing period, maturing period, and decaying period according to the fishing efforts. The point that we sustainably yield the maximum of fishery resources is the changing point of maturing period and decaying period. We call this point MSY, so the resources of fishing ground should be managed by the MSY. Therefore, when we select the fishing ground location. We should judge the natural factor, the economic factor and the social factor synthetically according to the situation and environment, so we can achieve the efficient management.
