Analysis of Financial Ratios of the Korean Coastal Passenger Shipping Company and Proposal for Improving their Business Performances
Journal of the Korean Society of Marine Environment & Safety, volume 8, issue 1, 2002, Pages 1~14
This paper discusses the analysis of financial ratios of the Korean coastal passenger shipping company 1997 and 2000. Coastal passenger shipping company shows a very high ratio of the fixed-assets because these shipping company own relatively expensive ships. The current debts are composed of short-term borrowings and lease and the ratio of the current debts is rather high considering to the size of shipping company. The equity ratio of passenger shipping company has recently been decreased, but the debt ratio has been increased. Both the profitability and activity ratios have grown worse in recent years. In order to improve the performance of coastal passenger shipping company, they should develop the leisure facilities and good items to attract travellers.
A Comparative Study on Risk Management Systems for Hazardous and Noxious Substances at Sea, in Korea and USA.
Journal of the Korean Society of Marine Environment & Safety, volume 8, issue 1, 2002, Pages 15~52
According to International Maritime Organization. more than 50% of cargoes transported by sea today can be regarded as dangerous or hazardous ones, mainly consisting of chemical cargoes in bulk, likely solid or liquid and other materials, such as gases and products for and of the oil refinery industry. 46% of total cargoes handled in ports of Korea in 1999. is said to be dangerous cargoes. These dangerous and hazardous cargoes are quite within a high realms of possibility of accidents, likely to be grave disaster. This paper reviews current risk management system for the dangerous and hazardous cargoes sea-transportation, mainly focusing on the prevailing regal regimes in both USA and Korea. And it aims to suggest some points for advancing the existing Korean system.

The state-of-the-art suits for one-man operation by integration of conning information and central information presentation. Further, it is desirable to enable two man ship operation for emergency operations, training purposes and redundancy. In this point of view, this thesis would like to design a conceptual bridge.
APPLYING THE THEORETICAL CONCEPT OF SUSTAINABILITY TO THE DEVELOPMENT OF PUBLIC POLICY
Song, Jae-Shuck ;
Journal of the Korean Society of Marine Environment & Safety, volume 8, issue 1, 2002, Pages 61~80
Since the 1980s, no concepts have been paid more attention to in discussions of environmental policy and natural resource management than ″sustainability″ and ″sustainable development.″ The concepts, however, are still vague and elusive even though they are frequently being used by a wide range of fields including academia. governments, and the private sector. To identify the diversity, range and concepts of sustainability. this paper will conceptualize the theoretical paradigms and social implications of sustainability and will develop general principles in Public policy.
Study on the Design of Shaft Strut for Naval Ships with Twin Screw
Journal of the Korean Society of Marine Environment & Safety, volume 8, issue 1, 2002, Pages 81~87
High speed naval ships are configured with open shafts The shafts, bearings, and propellers are supported by shaft struts. Proper design of struts involves issues of structural, vibration, and hydrodynamic analysis and design. Strut arm cavitation in high speed occurs because of a misalignment of the strut arm with the local incident flow. Proper selection of the strut section can minimize the generation of cavitation. This paper describes issues in the design struts and notices based on the design of Patrol Craft and Amphibious Ship.

A Study on Unsteady Flow Characteristics of Triangular Grooved Channel
Journal of the Korean Society of Marine Environment & Safety, volume 8, issue 1, 2002, Pages 101~108
This experimental study was performed to investigate internal flow and unsteady flow characteristics using a model for actual shape of a Plate heat exchanger and visualization of flow through the particle image velocimetry. Seven Reynolds numbers were selected by calculation with the height of grooved channel and sectional mean velocity of inlet flow in the experiment, and instantaneous velocity distributions and flow characteristics were experimently investigated. The triangular grooved channel had a compound flow consisting of the flow in lower channel and the groove flow receiving shear stress by the channel flow in the experiment. The sheared mixing layer, in the boundary between the triangular groove and the channel. affected main flow to raise turbulent in the channel.
Comparative Analysis of Maritime Safety Administrative System in the APEC Region
Chang, Hak-Bong ;
Journal of the Korean Society of Marine Environment & Safety, volume 8, issue 1, 2002, Pages 109~125
This paper has dealt with the efficiency of maritime safety administrative system in the APEC region. under the hypothesis that officient maritime safety and marine environment. Many factors affect administrative structures, which generate various types of administration. The factors include social, economical and political factors. Further, the addition of historical factors to these factors makes it tougher to draw out an optimal model for maritime safety administration. In this regard, the result of this study will be within the extent of volition capable of accepting it under the existing maritime safety administration system. The result of the study to help APEC member states(economies) to compare their own system with those of other economies and finally to help to improve their maritime safety administrative structure for safer shipping.
A Web-based Solver for solving the Reliability Optimization Problems
Journal of the Korean Society of Marine Environment & Safety, volume 8, issue 1, 2002, Pages 127~137
This paper deals with developing a Web-based Solver NRO(Network Reliability Optimizer) for solving three classes of reliability redundancy optimization problems which are generated in series systems. parallel systems and complex systems. Inputs of NRO consisted in four parts. that is, user authentication. system selection. input data and confirmation. After processing of inputs through internet, NRO provides conveniently the optimal solutions for the given problems on the Web-site. To alleviate the risks of being trapped in a local optimum, HH(Hybrid-Heuristic) algorithm is incorporated in NRO for solving the given three classes of problems, and moderately combined GA(Genetic Algorithm) with the modified SA(Simulated Annealing) algorithm.
A Study on the Required Stockpiles of Marine Oil Spill Response Equipments in the Busan Area
Journal of the Korean Society of Marine Environment & Safety, volume 8, issue 1, 2002, Pages 139~148
As the Busan harbor is getting susceptible to oil Pollution. the authors analyze the historical records of oil spill accidents and investigate the shoreline features. In addition. we evaluate the response capabilities and compute the required stockpiles of marine oil spill response with the worst case scenario in this area. As a result, it is shown that the recommendable oil spill response is to contain and mechanically recover all oils at sea surface in winter. while chemical dispersants can be used in summer with mechanical containment and recovery, and it is also found that off-shore booms of 3,000m and off-shore skimmers of 986MT/hour recovery rate should be stockpiled with 10,000∼60,000 liters of concentrate chemical dispersant and small amount of synthetic organic sorbents for possible use.
