Since the inception of the Paris Memorandum of Understanding 1982, Port State Control has been recognised as one of the most effective measures available to eradicate substandard shipping from the oceans of the world. This paper explains the basis, genesis and developmt of cooperative arrangements in Port State Control, and aims to suggest that Korea government and shipwoners should be ready to response to the adoption of cooperative arrangement in Port State Control of Asia-Pacific region.
There are numerous mapping, charting, geodetic systems and electronic digital products defined in various local geodetic datum. It becomes a straight forward requirement to simplify the complexity by referencing all the products to a common reference globally. WGS-84 is well known as a state-of-the-art global reference system based on the use of data, techniques and technology available within American Defence Mapping Agency(DMA). Its parameters can be translated into more accurate maps, charts and geodetic positioning compared to others previously. Since Global Positioning System(GPS/NAVSTAR), which is asssociated with World Geodetic System(WGS-84)in reference frame, has been widely used, the unified geodetic system has been required for GPS users in many fields.
We measured lagrangian currents in the coastal regions off east coast of Korea. The experiment sites are the Ulijin region where Polar Front of the East Sea is formed and the Ulgi region where coastal upwelling occurs frequently in summer. Each drifters are equipped with GPS receiver, and their trajectories are montiored by receiving the data transmitted from drifters through radio signal. The experiment with 'transmitting' GPS is very useful in monitering flows in coastal regions. Trajectories of drifters in the Uljin Polar Front region in October 1994 showed counterclockwise flow pattern. The flow pattern agrees with the SST distributions obtained from NOAA-11 AVHRR image for the same period. The lagrangian trajectories of drifters at 5m and 15m depths in the Ulgi region for normal period of April 1995 showed that the currents at the top 15m layer are almost uniform and their magnitude is 29cm/s. However, the currents, measured by KORDI, during the upwelling period of June 1994 showed that the currents at 5m depth were 1.2 times stronger than those at 15m depth. The current pattern in the Ulgi upwelling region agrees with the horizontal and vertical distributions of seawater temperature measured by NFRDA at the same period.
This study examines experimentally and theoretically, the wave deformation by two large cylindrical structure in relation to the case of one structure. The wave height around the structures varies, according to the changes of the incident wave angles, the number of the structure, and the distances between the two structures. The wave deformation around the large cylindrical structures is shown to be well predicted theoretically by the diffraction theory based on the singular point distribution method using a vertical line wave source Green's function.
This study is concerned with developing a heuristic algorithm for solving a class of ninlinear integer programs(NLIP). Exact algrithm for solving a NLIP either may not exist, or may take an unrealistically large amount of computing time. This study develops a new heuristic, the Excursion Algorithm(EA), for solving a class of NLIP's. It turns out that excursions over a bounded feasible and/or infeasible region is effective in alleviation the risks of being trapped at a lical optimum. The developed EA is applied to the redundancy optimization problems for improving the system safety, and is compared with other existing heuristic methods. We also include simulated annealing(SA) method in the comparision experiment due to ist populatrity for solving complex combinatorial problems. Computational results indicate that the proposed EA performs consistently better than the other in terms of solution quality, with moderate increase in computing time. Therefore, the proposed EA is believed to be an attractive alternative to other heuristic methods.
The purpose of this paper is to develop an integrated environment system for finite element structural analysis using OOA(Object-Oriented Analysis) and OOD(Object-Oriented Design), with may reduce inconveniencies in use such as file input of macro command and improve lacks of graphic presentation in the established finite element analysis program. This paper is attempted to suggest an easy approach to object-oriented concept and convenient programming. Two languages are used together in this paper instead of single C++ language for the development of object-oriented program. : Visual Basic with CDK(Custom Development Kit), and Borland C++ with OWL(Object Windows Library).
This study is concerned with the efficient improvement in the shipboard training of trainees for the marine officers in the future. The shopboard training course is given much weight in the curriculum of the seamanship education for the characteristics of that. In spite of various earlier studies to improve shipboard training system, we don't have desirable one until now on this problem based upon practical and empirical analysis. It seems a matter of urgency should be settled to improve the training environment-training facilities and equipment including simulator education - for the efficient pratice off-shore during training vessels in port. And it is also desired to regulate downward the credit system needed to graduate that trainees should be immersed in their practice without regard to their school records if passed the course during the training period.
This study is for decision making on distribution of resources so as to improve the effectiveness of initial disaster relief efforts. It is very important that relief efforts should be accomplished appropriately at the initial disaster. Furthermore, efficient allocation of relief resources such as rescuer, shelter, relief goods, relief funds, medical and relief equipments is also the first step to achieve main objective of relief efforts when disaster occurs. For this purpose, this study establishes flood as a imaginery disaster and develops a model for efficient distribution of resources when flood outbreaks. This model fixes initial 72 hours, which is subdivided into three intervals, as a initial disaster range. The model is to set a prioity against alloction of relief resources by each time zone which is related to damaged degree( Red Tag, Yellow Tag, Green Tag). Experts in this field input their experience into this model, and these are analyzed by Analytic Hierachy Process(AHP)/Expert Choice(EC) software. Therefore, we can decide a prioity against distribution of resources by each time zone which is in accordance with damaged degree. The result of this study would be helpful to a person who is in charge of relief from calamity in order him to make a decision toward distribution of resources.
It is argued that conventional behavior of government, industry, and the public in managing the seas is dysfunctional and must change. Industry manipulation of government regulatory processes, the public complacency that allows it, and its consequences are discussed. Resolving this problem will reqire industry to embrace a code of environmental ideals such as the Coalition for Environmentally Responsible Economies(CERES) principles. A new emerging 'corporate environmentalism' is discussed.
먼저 이 곳 한국해양대학교에서 캐나다 코스트가드를 소개할 수 있게 되어서 대단히 영광스럽게 생각하며, 지금부터 발표를 시작하겠습니다. 기존의 캐나다 코스트가드(the Canadian Cost Guard :C.C.G)는 운수성에서 수산·해양부로 이관·통합되면서 해양관리의 중요한 위치를 차지하고 있다. 본인은 이 시간에 통합 이 후의 C.C.G가 어떠한 조직으로 구성되어 있으며, 해양관리를 위해서 어떠한 기능을 수행하고 있는지에 대한 내용을 소개하고자 한다.
