Recently, Trouble of sand supply is occurred according to exhaustion of natural sand resources. therefore, various measures are proposed for solution of trouble of sand supply. also the government settled trouble of sand supply through application of EEZ sand and crushed sand. but because both EEZ sand and crushed sand are poor against general sand, they lead to lowering of quality of ready-mixed concrete. Therefore, this study evaluated physical properties of mortar using EEZ sand and crushed sand and applied evaluation result to fundamental data The result of this study have shown that quality of mortar using EEZ sand and crushed sand independently is poor against general mortar. but, mortar flow and compressive strength is increased in case of mixing 222 sand and crushed sand properly.

Recently, trouble of sand supplying is occurred according to exhaustion of natural sand resources. Therefore various measures are proposed for solution of trouble of sand supply and crushed sand among measures is used as one of most universal measures. But because crushed sand have poor particle shape and plenty of makes micro particle, the quality of concrete using crushed sand deteriorated. Therefore, this study evaluated engineering property of concrete with replacement ratio of crushed sand and EEZ sand and applied evaluation result to fundamental data for quality control of concrete using crushed sand and EEZ sand. The result of this study have shown that quality of concrete using crushed sand and EEZ sand and The compressive strength of concrete up to 50, 70% EEZ sand replacement by crush sand, nearly equal to that of general sand.

Ieodo is a submerged rock within a Korea's Exclusive Economic Zone(EEZ) in the East China Sea with its most shallow part about 4.6m below the sea level which has no specific rights for the EEZ delimitation. The United Nations Convention on the Law of the Sea (UNCLOS) stipulates that any coastal state has the rights to claim an EEZ that stretches up to 200 nautical miles from its shore, except where there is an overlap with a neighboring country's claims. Korea claims that Ieodo is within its EEZ as it sits on the Korean side of the equidistant line and the reef is located on the Korea section of the continental shelf. China does not recognize Korea's application of the equidistance principle and insists that Ieodo lies on its continental shelf. According to UNCLOS, Ieodo is located in international waters, rather than one country's EEZ as the two countries have failed to reach a final agreement over the delimitation of the maritime border. This study seeks to understand the evolution of the People's Liberation Army Navy(PLAN) strategy as main obstacles for the EEZ delimitation between Korea and China. PLAN's Strategy evolves from "coastal defense" to "offshore defence", since the late 1980s from a "coastal defence" strategy to an "offshore defence" strategy which would extend the perimeter of defence to between 200 nm and 400 nm from the coast. China's economic power has increased It's dependence on open trade routes for energy supplies and for its own imports and exports. China want secure Sea Lane. PLAN's "offshore defence" strategy combines the concept of active defence with the deployment of its military forces beyond its borders. China's navy try to forward base its units and to achieve an ocean going capability. China's navy expects to have a 'Blue Water' capability by 2050. China insists that coastal states do have a right under UNCLOS to regulate the activities of foreign military forces in their EEZs. China protests several times against US military forces operating within It's EEZ. The U.S. position is that EEZs should be consistent with customary international law of the sea, as reflected in UNCLOS. U.S. has a national interest in the preservation of freedom of navigation as recognized in customary international law of the sea and reflected in UNCLOS. U.S. insists that coastal states under UNCLOS do not have the right to regulate foreign military activities in their EEZs. To be consistent with its demand that the U.S. cease performing military operations in china's EEZ, China would not be able to undertake any military operations in the waters of South Korea's EEZ. As such, to preserve its own security interests, China prefers a status quo policy and used strategic ambiguity on the Ieodo issue. PLAN's strategy of coastal defence has been transformed into offensive defence, Korea's EEZ can be a serious limitation to PLAN's operational plan of activities. Considering China'a view of EEZs, China do not want make EEZ delimitation agreement between Korea and China. China argues that the overlapping areas between EEZs should be handled through negotiations and neither side can take unilateral actions before an agreement is reached. China would prefer Ieodo sea zone as a international waters, rather than one country's EEZ.

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.

이 논문은 일본의 배타적 경제수역(EEZ)에서 한국어선의 피납실태를 분석하여 그러한 문제에 대한 대응방안을 제시하는 것을 그 목적으로 한다. 일본의 배타적 경제수역에서 벌어지고 있는 한국어선의 피납실태를 분석해 보면 우리나라의 어민들이 연근해 수산자원의 고갈과 해양오염으로 인하여 연근해조업이 곤란한 상황에서 수산자원이 풍부한 일본의 배타적 경제수역 경계선 부근이나 경계선을 침범하여 조업을 하고 있는 것으로 나타난다. 과거에는 그러한 행위가 관행상 자유로운 공해상의 조업이었지만 UN해양법협약(1994)과 한일어업협정(1999)이 발효함으로써 범법 행위가 되었다. 그러한 문제를 해결하기 위해서는 장기적인 관점에서 어업정책의 방향전환, 어민들의 생계대책마련 및 한일양국의 어업관리 협조체제의 구축이 필요하다. 무엇보다 당장 시급한 것은 외국에서 집행된 형의 감면이며, 어업지도와 단속을 위한 인적·물적 자원의 확충 및 해양경찰과 해양수산부의 긴밀한 공조체제 구축도 시급한 것으로 보인다.

With it being inevitable to change the method of supervising as it is reorganized to EEZ coming out of the old concept of contamination in Korean area of the sea, it costs a lot to have good enough systems of total control for sea contamination and prevention of contamination as well as the effective marine superintendence because the governing bodies such as Ministry of Maritime Affairs and Fisheries, National Maritime Police Agency, and Authorities of Guiding Ships for Fishery, have their own source of laws and different ways to execute. In order to change such a wrong method of marine superintendence, it is necessary to conduct the merger and abolition of similar authorities with similar functions into authorities which are light but can be expected to play a major role, and to open the high-costing low-efficient organizations to make them remodel to be reborn as economical bodies. In addition to that, the maritime authorities, which are falling to incapable organizations not being able to work out any complicated tasks, have to be reborn as preventing bodies which take care of security and public peace and cut off a pollution source from sea and land.
