Enhancing Implementation Capability of National Maritime Administration for Preventing Marine Pollution
Journal of the Korean Society of Marine Environment & Safety, volume 1, issue 2, 1995, Pages 1~15
Almost of all impediments to enhancing ship safety and preventing vessel-source marine pollution arise from the interaction between direct and indirect factors. The direct factors come from human errors and failure in compliance with the international convention standards for the operation of cessel. The indirect factors derive from the will and attitudes of the countries taking little responsibilities with appropriate seriousness for policing their fleets. By focusing on these aspects, this paper reviews the effectiveness of existing countermasures adopted by IMO and intends to propose a new paradigm to improve the implementation capability of each nation by suggesting frameworks of maritime administration models.
A Study in Regime for Establishing Port State Control in Korea
Journal of the Korean Society of Marine Environment & Safety, volume 1, issue 2, 1995, Pages 17~37
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.
A Study on the Ocean Safety According to the Geodetic Datum Transformation
Journal of the Korean Society of Marine Environment & Safety, volume 1, issue 2, 1995, Pages 39~52
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.
Lagrangian Observations of Currents in the Coastal Regions off East Coast of Korea
Journal of the Korean Society of Marine Environment & Safety, volume 1, issue 2, 1995, Pages 53~60
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.
Wave Deformation by Large Cylindrical Structures
Journal of the Korean Society of Marine Environment & Safety, volume 1, issue 2, 1995, Pages 61~67
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.
Development of a Heuristic Method for Solving a Class of Nonlinear Integer Programs with Application to Redundancy Optimization for the Safely Control System using Multi-processor
Journal of the Korean Society of Marine Environment & Safety, volume 1, issue 2, 1995, Pages 69~82
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.
Development of Finite Element Structural Design System using Object-Oriented Concept
Journal of the Korean Society of Marine Environment & Safety, volume 1, issue 2, 1995, Pages 83~94
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).
A Study on the Efficient Improvement in the Shipboard Training
Journal of the Korean Society of Marine Environment & Safety, volume 1, issue 2, 1995, Pages 93~105
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.

Decision Mking for Efficient Resource Allocation in Initial Disaster of Flood
Journal of the Korean Society of Marine Environment & Safety, volume 1, issue 2, 1995, Pages 107~118
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.
Government, Industry and Public Management of the Seas in the 21st Century
Journal of the Korean Society of Marine Environment & Safety, volume 1, issue 2, 1995, Pages 133~138
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.
