난바다곤쟁이는 북태평양 동부해역으로부터 베링해, 오우츠크해, 동해와 황해에 이르기까지 광범위하게 분포하는 종으로서 형태학적 분류관점에서 동일종으로 간주되고 있다. 최근에 밝혀진 황해 개체군의 생태학적 특성에 의하면 미국 서부해역과 황해에 서식하는 두 개체군은 지리적으로 멀리 떨어져 있음에도 불구하고 공히 비교적 낮은 수온 (< 1$0^{\circ}C$)의 수심에서 서식하며 강력한 일주수직상승운동 (diurnal vertical migration)을 수행하는 등 많은 특성을 공유하는 것으로 밝혀졌다 (Yoon et al., in press). 본 연구는 미국 서부연안과 한국 서해에 서식하는 난바다곤쟁이 개채군의 물리, 생태, 형태학적인 공통 특성이 유전학적인 측면에서도 관찰되는지를 조사하고자 한다.

선박의 조종성능은 풍조나 파랑등 외력에 의한 영향이나 그 선박의 홀수, 속력등 항행환경에 따라서 조종성능이 달라 질 뿐만 아니라 조타에 대한 선체의 응답운동이 달라지게 된다. 따라서, 조선자는 선박이 항행중 다른 선박이나 위험물에 접근 했을 때 안전하게 피항하기 위해서는 그 선박에 대한 선회성과 추종성 등 조타에 의한 조종 성능을 잘파악하고 있어야 하며, 이러한 조종 성능은 일반적으로 선회시 선회권에 의한 종거 및 횡거와 선회경의 크기로 결정되는 선회성과 조타에 의한 선체운동등 추종성을 나타내는 조종성 지수로써 그 선박에 대한 조종성능의 양부를 판별하게 되는 것이다.

인공방사성 물질이 해양으로 유입되는 경로는 대기권 핵실험에 의한 낙진, 원자력 관계시설에서 액체 방사성물질의 유출, 방사성패기물의 해양 투기 등이 있다. 현재 해양에서 검출되고 있는 인공방사성 핵종은 대부분이 과거의 핵폭발실험에 의해 해양으로 유입된 방사능 물질이 해양내에서 이동되어 검출되는 것으로 볼 수 있다. 이들 핵종 중에서 반감기가 긴 핵종($^{137}$Cs, $^{90}$ Sr, $^{238}$ Pu, $^{239+240}$ Pu)은 방사능 오염의 좋은 지표 일 뿐만 아니라 연안퇴적물의 거동과 분포를 이해하는데 유용하다.

Insulin-like growth factor-I(IGF-I)은 70개의 아미노산으로 이루어진 polypeptides로서 pronsulin과 구조적으로 유사하다(Froesch and Zapf, 1985). IGF-I은 척추동물에서 성장호르몬의 매개로 생성되어 동물의 성장 발달에 중요한 역할을 하고 있으며 세포의 성장, 분화, 대사에 다양한 효과를 보여주고 있다(Cohich and Clemmons, 1993; Baxter, 1993). 또한 체성장을 가속화시키고 in vivo에서는 단백질의 합성을 촉진시킨다(Rotwein et al., 1987). (중략)

Nowadays managers of fisheries enterprises and users of accounting information have a considerable interest in the fishery right. The fishery right, which is given by administrative quarters, is referred to exclusive fishing right in a certain coastal fishing ground, and it has been one of the property rights since the turn of the century. The main purpose of this study is to provide an improved accounting method of the fishery right from the side of accounting. To achieve this purpose, legal nature of the fishery right should be understood in the first place, for the fishery right, an intangible asset, is a sort of property right guaranteed by the fisheries laws, According to the basic law in the fisheries "Fisheries Law, " the fishery right is broken down largely into three categories; culture fishing right, set fishing right and common fishing right. The legal characteristics of these fishery rights are as followings: 1. The fishery right is a private right. 2. The fishery right is a property right. 3. The fishery right is a right in rem, and legal provisions pertaining to land are applied to the fishery right with necessary modifications. In addition to the above fishery rights, the Fisheries Law provides some provisions on the so-called entrance right, and those who obtained the right are authorized to access to a certain common fishing right fishing ground where they have been traditionally fishing. In the inland fisheries, the fishery right system similar to that of the coastal fisheries discussed above is adopted in conformity with the Inland Fisheries Developing and Expediting Law. Viewing from an angle of accounting, there are two kinds of additional fishing rights which are dealt as assets. These fishery rights dealt as asset include the license of entry in the so-called permitted fishing which is also called as fishery right in plain language, and tile entrance right obtained abroad. Although these two kinds of rights are not the fishery right from a viewpoint of law, they are regarded as fishing rights in accounting which intends to provide a useful economic information.formation.

This study regards that a cause of intensifying sovereignty disputes between Korea and Japan over the Dokdo island has resulted from the fallacy of Dokdo's development policy directly related to exertion and consolidation of Korean government's sovereignty on Dokdo, which has been under Korea's effective control since 1953. From this internal view, this study critically reviews the Korean government's development policy for Dokdo from the 1950s to the end of July 2012 and suggests an ideal alternative for future development of Dokdo on the basis of the discussion of the problems of Dokdo's development policy and its different future development directions proposed in Korean society. The Korean government implemented quite passively the development policy for the inhabited island which is required for the consolidation of sovereignty over Dokdo not to hinder the friendly diplomatic relationship between Korea and Japan. Dokdo is currently not acknowledged as the Korea's Dokdo island in international society, but mostly called Liancourt Rocks. It may be due to the fact that Korea did not positively develop Dokdo as a valuable island which a number of Koreans can inhabit. Consequently this paper proposes 'Dokdo eco-village' as an alternative development plan from the perspective of sustainable development which the UN has adopted. It is a small scale village that contains economic function of eco-friendly fishing, eco-tourism and East Sea research. The hope is that Dokdo eco-village draft plan will be a clue to the discussion and establishment of new Dokdo's development policy to strengthen the Korea's sovereignty and effective control over Dokdo in the future.

The government is largely responsible for preventing “the tragedy of the common property”, but fisherman's effort fer an autonomous fishery control is equally required. Especially in these days of EEZ such self- regulated fishery management system should be developed and cared for as well. This study aimed to explore a proper management system for coastal fishing ground that now requires the responsible fisheries management by investigating and analysing more drastically the managerial functions of fishery right by Eochon-Gye(the smallest unit of fisheries cooperative based on a fishing village), a typical fishery producer's organization in Korea. This study also included such contents as (1) an understanding of fishery producer's organization, (2) the utilization and management system of coastal fishing ground, (3) the actual condition of fishing right distribution in Korea, (4) the fishery right management and activity of Eochon-Gye, (5) the operation and distinctive feature of fishery right in Japan, (6) the intervention and limit of fishery producer's organization for fishing ground management function, and (7) summary and proposal. We made all Eochon-Gye of the whole country an object of this study and carried out an investigation into Eochon-Gye through a questionnaire. We extracted 359 Eochon-Gye, 20% of the total 1,719 Eochon-Gye as a random sample and investigated these regions through a questionnaire by mail. The contents of the questions consist of 40 items, including six categories about the organization of eochon-gye, and fishing ground management and activities.

Due to a publicly owned resources, the overexploitation of the fisheries resources can result in externalities in the form of reduced future levels of yield. These problems can be theoretically improved through effective management of the fishery. The paper illustrates maximum sustainable yield(MSY), maximum economic yield(MEY) and F0.1 level of fishing mortality as the concept of optimal yield, and it theoretically shows that MSY is more appropriate for the optimal yield than MEY where prices increase even though MEY achieves the maximization of economic rent in a fishery assuming constant prices. And the paper presents several fisheries management tools and policies such as input controls, output controls and taxes. As the traditional approach to fishery management, input controls involve restrictions on the physical inputs into the production process(e.g. capital, time or technology) and output controls involve limits on the quantity of fish that can be landed. To introduce user cost into the harvest decisions of rent-seeking fishers, taxation, as a bioeconomic management policy of the fisheries, directly addresses the problems associated with the resource being unpriced. As most fisheries management plans, however, have increasing fisher income as an objective, taxes have not been introduced into any fisheries management policies despite their theoretical attraction.

As the UN Fish Stocks Agreement has come into effect since 2001, the actual enforceable management on fish stocks in high seas has started. The Regioanl Fisheries Organizations (RFOs) have emerged as management bodies with a real responsible right to manage fish stocks. RFOs establish a strong and strict management rules providing a fishing right only to member countries and preventing all fishing activities from fishing vessels of non-member countries. In addition, RFOs have an own allocation way of fishing opportunity in their waters so that they can prevent the depletion of fish stocks. It is investigated that deep-sea fisheries have a negative impact from strengthening of RFOs' management right. As the amount of catch is reduced by the control of fishing vessel's activities, the level of fishing revenue becomes low. Moreover, as fishing costs such as oil, fishing fees, labor cost increase significantly, the condition of fishing business is getting worse as a result. In order to gain a fishing right for deep-sea fishing vessels in RFOs waters, there is no other alternative way but become a member of RFOs which are relevant to our fisheries but not joined.

From July to early September 2012, there was mass mortality of fishes, particularly black rockfish, which were being raised in the floating fish cage along the coast of Gyeongsangnam-do. The amount of damage was 1,802,000 fishes and the causes were confirmed to be rapidly rising water temperature and repeated daily changes in water temperature. The water temperature in this area of the sea rose to the maximum $28.4^{\circ}C$ and the daily range of changes in water temperature was maximum $6.5^{\circ}C$. As a result of investigating biological diseases of 194 fishes in 49 fishery areas, major pathogenic organisms such as red seabream iridovirus (RSIV), Vibrio sp. and Vibrio spp. or Microcotyle sp. were detected in rockfish in some fish farms. It is considered that the major causes of the mass mortality were high water temperature accompanied by repeated daily changes in water temperature, it is considered that biological diseases influenced the increase in the perish of fishes.
