This article's aim is to review the jurisprudence which has emerged pursuant to the international dispute settlement provisions and to provide a provisional expectation as to the future of international dispute settlement under "UNCLOS". Globally, marine fisheries play an important role in ocean biodiversity and the food security of millions of people, providing a vital source of high-quality dietary protein and supporting individuals' livelihoods and income. In the 1982 Convention, the establishment of co-operative mechanisms for effective monitoring, control, surveillance and enforcement, decision-making procedures facilitating the adoption of such measures of conservation and management, and the promotion of the peaceful settlement of disputes are called for. In this study, 'Northeast Asian Sea' means that the Yellow/East China Sea, the East Sea, the Ohotsk Sea, the Kamchaka Sea, the Alaska Sea, and the Bering Sea surrounded by Korea, China, Japan, Russia, U.S.A. and Canada including their EEZs. There are several bilateral fisheries agreements existing in Northeast Asian area, the Fisheries Agreement between Republic Korea and Japan, between Republic of Korea and China, between China and Japan, between Republic Korea and U.S.A., between Republic Korea and Russia, between Russia and Japan, And there are several regional fisheries organizations existing in Northeast Asian area, for example NPAFC(Convention for the Conservation of Anadromous Stocks in the North Pacific Ocean), CBSPC (Convention on the Central Bering Sea Pollack Conservation), PICES(North Pacific Marine Science Organization), NPFC(North Pacific Fishery Commi-ssion) etc. It analyzed the proliferation of bilateral treaties and multilateral treaties due to the adoption of the EEZ in Northeast Asia reviewed the strengthening of management rights on the high seas marine living resources and marine environment preservation of regional fisheries organizations. In view of the changes in the international fisheries mechanism this paper suggested the future direction of the country in overseas fisheries. We concluded as follows. We shall apply bilateral treaties first, regional fisheries organizations' treaties secondly, and provisions under "UNCLOS" for dispute settlement last.

The authors investigated the existing international fishery relationship in the sea around the Korean Peninsula, and prospected on the reformation of the fishery order which might be followed by mutation of the international political condition and by effectuation of the U.N. Convention on the Law of the Sea in the future. It can be explained that the existing international fishery order in this sea has been constituted on the basis of restricting Japanese indiscriminate fishery expansion. But. when the South Korea and China proclaim the 200-mile EEZ in the future, a considerable part of existing fishery agreements will forfeit the role as general norms of the international fishery relationship. Accordingly a counterplan against the revision or abrogation of the Korea-Japan Fishery Agreement must be considered. And also a rational fishery relationship between Korea and China, as confronting countries, must be organized. The South-North Korea fishery relationship must be settled on the basis of co-operation. trust, and common interest. For this purpose, a political discussion on the establishment of the joint fishery zone around the military demarcation line and on the conservation for the fishery resources must be begun in earnest.

The purpose of this study is to suggest improvement directions and strategies for the minimization of ex-post damage and prevention of the generation of derelict fishing gear which lead to decreased fisheries resources and deteriorated marine ecosystem through ghost fishing and damaging spawning and growth grounds. Current problems related to derelict fishing gear in Korea are lack of reliable data on the generation amount of derelict fishing gear, absence of life-cycle monitoring and management system, insufficient supports for derelict fishing gear collection programs and R&D investment in environmentally friendly fishing gear, etc. Thus, this study suggests three basic improvement directions to prevent the generation and minimize the damage of derelict fishing gear. Such improvement directions contain more detailed strategies such as establishment of fishing gear management law and life-cycle management system, strengthening entry regulations on fisheries causing serious ghost fishing problems, increased supports for R&D investment and dissemination of bio-degradable fishing nets, and promotion of voluntary agreements among competing fishermen's groups.

The worldwide proliferation of regional trade agreements combined with rising interests of 37countries has led to the emergence of a possible GSTP between each country. Although there are many obstacles to GSTP, its effect, if a realized, will go beyond trade related issues. This study was to specify and estimate a model of Korea-GSTP Ground in Korea that can be used to evaluate and improve management decisions. The development of the model relied on several submodels. On the trade negotiation side, a import demand function was estimated in order to account for the increasing amount of import. In terms of margin of preference(MOP)s, they were used to estimate values after decreasing tax based on scenarios I, II, and III. The results showed that the highest effects for increasing value and amount of import are a freezing crab(HS code 0306143000) and freezing hairtail(HS code 0303793000). This paper will be provide to help policy makers understand the Korea-GSTP Ground in the Korea fishery.

The effect of change in exchange rates on an economy is very important, especially, to a small open economy like South Korea. I explore whether Free Trade Agreements (FTAs) have positive influences on exchange rate-pass through import price of import market for fishery products in South Korea. Competition among FTA partners is enhanced after FTAs are effective. I expect that the extent to which are exchange rate pass-through (hereafter, ERPT) into import price of fishery products (in terms of Korea currency) would be reduced since the import market for fishery products in South Korea is an oligopolistic market. Specifically, I investigate two research questions with six South Korea's FTA partners-Norway, Thailand, Peru, U.S., China and Vietnam. First, whether the extent to which are exchange rate pass-through into import price of fishery products from six FTA partners would decrase in the post-FTA era; seconds, the size of reduction has a negative relation with the size of their market share in the import market for fishery products in South Korea if it decreases. The empirical results indicate that the degree of ERPT into import price from other FTA partners than Norway has been reduced after FTA, statistically and significantly; however, I do not find the evidence that the size of reduction is related to their market share. The findings in this study imply that FTAs have negative effects on producers' economic welfare in South Korea's fishery industry by reducing the extent to which are exchange rate pass-through as well as reducing tariff barriers.

The water-quality control for coastal waters is continuously required in view point of the environmental protection. The purpose of this study is to simulate the hydrodynamic process and the dispersion phenomena of several pollutants in Suyeong Bay, Pusan. The present study employs the depth-averaged 2-dimensional model for nemerical simulation of the hydrodynamics and diffusion. The nemerical solution is obtained by ADI(Altenating Direction Implicit) scheme which is frequently used for tidal current and diffusion computations in the coastal zone. To verify the nunlerical results, the field observations of various water quality parameters such as COD, SS and nutrients were performed during the spring tide. In the results of this study, the computed tidal currents show the clockwise flows for ebb tide and counter-clockwise flows for flood tide. In comparison with the water-qualities in ebb tide and flood tide, there seems to be slightly deteriorated in ebb tide and especially near the estuary of Suyeong River. In flood tide, however, the water-quality near Kwangan Beach is deteriorated. The computed distributions of COD and SS are in god agreements with the observed ones, while those of $PO_4\;^{3-}-P\;and\;NO_3\;^--N$ show slight differences due to the complex transformation processes.

In this study, a new numerical procedure for the generation of a nonlinear tailored group of waves is presented. The procedure is based on the transient wave group technique. In order to integrate the nonlinearity during the wave propagation in the computational method, the Navier-Stokes equations are applied as governing equations. The governing equations are discretized by finite volume approximation. The deformation of the free water surface in each time step is pursued with a moving grid. A two-dimensional, numerical wave tank for the simulation of the wave propagation is developed and tested in detail. The numeric results are compared first with analytical wave theories and with measurements, in order to examine the correctness of the numerical wave tank. Wave surface elevation and associated fields of velocity and pressure are numerically computed and compared with measurements. Very good agreements show up.

A cartridge type hydraulic logic valve consists of simple two port valve whose poppet is closed or opened by means of pressure signal of a pilot line. Accordingly, the logic valve can be used not only for direction, flow and pressure control purpose but also for versatile function valve which enables all above mentioned functions. In addition, the valve has little internal leakage and pressure loss, superior response characteristics and easiness in making small block type valve. The above mentioned good performances being recognized recently, the logic valve has been used widely in the large scale hydraulic system such as a hydraulic press system, for the performance requirements of high speed operation and precise control characteristics. However, there are scarce reports until now, except for a few ones from Aachen Institute of Technology in West Germany, so it is necessary to be studied on development and investigation for practical application. This paper showed that the static and dynamic characteristics of a logic valve when the logic valve is used for directional control, to investigate the relations between the valve operating characteristics and the valve design conditions. From the above mentioned procedure, it was ascertained that the valve operation characteristics obtained by numerical analysis showed good agreements with experimental results. The representative results obtained are as follows; 1. During the valve is closing, the poppet velocity is almost constant in the logic valve. 2. The pilot pressure P sub(3) and the resistance R in the pilot line have much influences on the valve operation time. 3. Spring strength have not such a severe influence on the valve operating time. 4. The operation characteristics of the logic valve can be estimated with good accuracy comparatively by numerical analysis with the equations describing poppet motion.

The study, using the input-output analysis of 402 industrial sectors by Bank of Korea(BOK) and the resulting outcomes of price model, aims to evaluate the spillover effects the international fluctuations in crude oil prices have on the commodities prices and consequently, analyse the management and profitability of the offshore fisheries in Korea. At present, the fisher men are provided with tax-free oils for their fishing operations as specified under the Special Tax Treatment Control Law. However, the exhaustion of marine resources and new international fisheries agreements, which resulted in the loss of fishing grounds, made the stable catch even more unpredictable and the hike in the price of the international crude oil would have adverse effects on the fishing industry. The study revealed that the increasing rise in the price of crude oil would exert sweeping spillover effects on other industry sectors in general and accordingly, lead to a poorer performance by fisheries. The price spillover coefficients for the diesel oil was 0.6026, which would translate into the 42.6% increase in the prices of oil when the increase ratio of 73.3% for the base crude oil was applied based on the calculation methods employed in the study. This in turn increased the ratio of diesel oil required in the offshore fisheries from 23.3% to 16.6%, diminishing the ratio of current net profits to minus 2.0% from 4.2% otherwise. By fishing type, the Pair Trawl suffered current net profits loss most by ratio of minus 9.4% and other fisheries such as Coastal Stow Nets, Coastal Angling, Danish Sein also suffered ratio of 7% and more in the loss of current net profits. With the deteriorating fishing performance, coupled with the increasing international crude oil prices, it is urgently required that the authorities concerned deliberate in depth on such schemes as follows in efforts to secure stable fishing production. First, provision of large-scale storage facilities for oil is needed to timely adapt to the fluctuations in international crude oil prices. Secondly, in line with the stabilization of tax-free oil prices, duty levied on oils for fishing and tax collected from the refineries need to be tax-exempt. Thirdly, the beneficiaries from the provision of tax-free oil should be broadened, not limited to special fishing operation only. Fourth, investment in stabilization of the oil prices should be encouraged, possibly through funding from the formation of fisheries development funds underway.

Cooperative scientific research in Antarctic has been successful since the International Geophysical Year 1957/1958. Presently, 43 nations have joined the Antarctic Treaty as consultative parties or acceding states, and other treaties and agreements have evolved to conserve the integrity and to manage the resources of the Antarctic ecosystem. Although yet to be designated, tourism areas in Antarctica are under consideration. Due to its remoteness and vast magnitude, Antarctica's science is slowly emerging. Satellite technology has enabled observation of the progression of the ozone hole above Antarctica. Mineral exploitation has yet to take place, as has the transport of Antarctic icebergs to some arid nations. On the other hand, both seal and whale exploitations have occurred, devastating these populations. The lessons learned from past human greed are used to design krill and squid fisheries, though the life histories of these organisms are yet to be adequately understood. An ecosystem approach to managing Antarctic resource exploitation is essential. Procuring the needed logistics to do so is daunting, requiring the highest degree of international cooperation and educational outreach to nurture the needed effective scientific and engineering talent, both natural and social.
