This paper describes on the real-time monitoring of net setting and hauling process for fishing operations of Danish seine vessels in the southern waters of Korea as an application of a PC based ECDIS system. Tracking of fishing process was performed for the large scale Danish seine vessel of G/T 90 and 350 PS class using the fishing gear which the length of net, ground rope, head rope and sweep line including warp in both sides were 86m, 104m, 118m and 3,200m, respectively. Tracking information for net setting and hauling process was continuously recorded for 23 fishing operations performed on November and December, 2003. All measurement data, such as trawl position, heading, towing course and past track which was individually time stamped during data acquisition, was processed in real time on the ECDIS and displayed simultaneously on the ENC chart. The results indicated that after the separation of a marker buoy from Danish seiner, the averaged running speed of vessel and the averaged setting period while shooting the seine on the course of diamond shape to surround the fish school in the 23 fishing operations were 8.3 knots and 13.1 minutes, respectively. And with the maker buoy taken on board, the averaged running speed of vessel and the averaged towing period while closing the seine on the straight route was 1.0 knots and 47.0 minutes, respectively. After the closing stage of hand rope, the hand rope was towed by the averaged speed of 2.2 knots during the 13.0 minutes. The average area for route of diamond shape swept by sweep lines of the seine in 23 fishing grounds was $709,951.6m^2$. Further investigation is also planed to provide more quantitative tracking information and to achieve more effective surveillance and control of Danish seine vessels in EEZ fishing grounds.

처벌규정이 없는 불가벌적 대향자에 대한 공범규정 적용을 부정하여 처벌하지 않는다는 논거는 적극적인 관여행위까지 처벌하지 않는다는 문제점을 가지고 있다고 볼 수 있다. 이를 해결하기 위해서는 일반적인 불가벌적 대향자가 대향범 구성요건을 실현하기 위해 최소한의 정도를 초과하지 않은 경우에는 불가벌이지만, 최소한의 정도를 초과하는 경우에는 공범으로 처벌이 가능하다고 볼 수 있다. 또한 불가벌적 대향자가 보호받는 자이거나 기대가능성이 없는 경우에는 불가벌로 파악할 수 있다. 이와 같이 해석하는 것은 일방행위자에 대한 처벌규정이 없는 불가벌적 대향자에 대한 불가벌의 근거를 설명하는데 적합하다고 생각한다.

Tuna and tuna fishing extend over most of the tropical waters of the world oceans, especially, this study of the Indian Ocean and the fish and the fishing vessels are highly mobile. No country can deal in isolation with the problems of its tuna fishery and of any tuna fishery in its waters, without collaborating with other countries. This cooperation is often best established through some formal international mechanism. The essential requirements are for information-on the resources, the fishery, the trade-and to identify where management actions are needed to consore the resources or to maintain the economic or social function of the fishery. These will also usually require some form of international mechanism. With the changes in the Law of the Sea, the siuuation in respect of management of tuna-considered among the highly migratory species, requirng special treatment-has also changed. At present there are both uncertainty regarding tuna management and political arguments as to how such management can be best implemented. Bearing this in mind, together with the fact that only few tuna stocks have shown clear evidence of serious depletion through over-exploitation, present emphasis will be placed on information requirements. This study included compiling the data necessary to review the state of stoks in the Indian Ocean tuna fishing grounds. Information on the resources-where the fish are, their quantity, their movements, etc. is important, whether in planning development of new fisheries, or considering the need for collaboration with other countries (in ascertaining to what extent their catches may affect catches of the natoinal fleet) or for conservation measures. A major source of information is the statistics of for conservation measures. A major source of information is the statistics of catch and fishing effort from existing commercial vessels. These need to be assembled for all fisheries on the same stock on an oceanwide basis. The statistical data also need to be analysed and intepreted, and combined with biological data(e.g., on growth, mortality and migration rates) to provide information that is intelligible and useful for administrators and other decision-makers. This must also be undertaken on a resource-wide or ocean-wide basis. Finally, because of the world-wide similarities in the methods of datching, processing and marketing fish, there is a particular tut not exclusive need in those countries just beginning to develop their tuna fisheries-to have ready access to a syntheis of information on tuna, tuna biology and tuna fisheries and tuna fisheries economics and management on the Indian Ocean.

The article is devoted to the study of the issue of liability for the dissemination of inaccurate information on the Internet. The article emphasizes that now the public opinion of socially active segments of the population is mainly formed on the basis of not critical but subjective ("consumer") analysis of the received information. The modern realities show that the main source of its origin is the Internet: electronic media and, above all, the relevant social networks. The problem of dissemination by the mass media of inaccurate information obtained via the Internet is solved; it is seen in bringing the laws of Ukraine, which regulate public relations regarding the dissemination of information, into compliance with the Civil Code of Ukraine. The issues of development and implementation of new legislative acts aimed at regulating the status of subjects of informational relations on the Internet and establishing the grounds for their liability are also investigated.

Flash memories are one of best media to support portable computer's storages in mobile computing environment. The features of non-volatility, low power consumption, and fast access time for read operations are sufficient grounds to support flash memory as major database storage components of portable computers. However, we need to improve traditional transaction management scheme due to the relatively slow characteristics of flash operation as compared to RAM memory. in order to achieve this goal, we devise a new scheme called Flash Two Phase Locking (F2PL) scheme for efficient transaction processing. F2Pl improves transaction performance by allowing multi version reads and efficiently handling slow flash write/erase operation in lock management process. We also propose a simulation model to show the performance of F2PL. Based on the results of the performance evaluation, we conclude that F2PL scheme outperforms the traditional scheme.

China is defending the terrorist crime through the Anti-Terror Law and anti-terrorism criminal legislation. China's Anti-Terror Law and the Criminal Code Amendment (9), which were promulgated in 2015, provide legal grounds for preventing and hurting ever-growing terrorist crimes. In particular, China's amendment to the Criminal Code (9) is designed to rigorously enforce the legal framework for terrorist crimes, protect prejudicial rights that might be violated by serious terrorist crimes, and protect the penalties for terrorist crimes. However, China's anti-terrorism legislation still has drawbacks such as lack of systematicity, limited regulatory boundaries, and lack of rigorous penalties for the establishment of anti-terrorism legislation. To counter this, China's anti-terrorism legislation must strictly regulate the legal system of terrorist crimes, secure penalties, and prescribe anti-terrorism laws as professional chapters.

In this paper, we propose a plural subject account of group beliefs using grounding concept, which bridges the gap between the two main approaches of ACLs, the mentalistic accounts and the social commitment accounts. The key idea of this Gilbert's plural subject account of group beliefs is to extend the grounding logic into the common ground framework for the semantics of ACLs which is fully verifiable, fully formalized and easily applicable. Thus, we formalize the proper group belief concept using common ground framework and we define the semantics of the primitive speech acts of FIPA-ACL such as inform, request and confirm as case studies. Also, we illustrate our framework on an e-commerce agent purchase negotiation and compare this proposed framework with two traditional semantics for ACLs.
