A ship handling simulator is popular means of preventing marine accidents caused by human error. It can also be used to train navigators. A real-time 3D visualization system, a component of a ship handling simulator, is an important component, as realistic and intuitive image generation play an essential role in improving the effects of education using ship handling simulators. This paper discusses the design of a new real-time 3D visualization system based on an open source 3D graphics engine as well as its implementation. The developed real-time 3D visualization system satisfies the operational requirements derived in terms of visualization functionalities, reuse of legacy graphic data, and interoperability with other systems constituting a ship handling simulator. This system has an architecture in which new functionalities are easily added.

The authors adopt the Unmanned Undersea Vehicle(UUV), the shape of which is like a manta. They call here it Manta UUV. Manta UUV has been designed from the similar concept of the UUV called Manta Test Vehicle(MTV), which was originally built by the Naval Undersea Warfare Center of USA(Lisiewicz and French, 2000; Simalis et al., 2001; U.S. Navy, 2004). The present study deals with the effect of Reynolds numbers on hydrodynamic forces acting on Manta UUV at large angles of attack. The large angles of attack cover the whole range of 0 to
180 degrees in horizontal plane and in vertical plane respectively. Static test at large attack angles has been carried out with two Manta UUV models in circulating water channel. The authors assume that the experimental results of hydrodynamic forces (lateral force, yaw moment, vertical force and pitch moment) are analyzed into two components, which are lift force component and cross-flow drag component. First of all, Based on two dimensional cross-flow drag coefficient at 90 degrees of attack angle, the cross-flow drag component at whole range of attack angles is calculated. Then the remainder is assumed to be the lift force component. The only cross-flow drag component is assumed to be subject to Reynolds number.entstly the authors suggest the methodology to predict hydrodynamic derivertives acting on the full-scale Manta UUV.

As the increase in maritime traffic and leisure, the marine accident risk has increased in the domestic coast. In this study, the cause and the environment of domestic marine accidents from 1990 to 2009 have been investigated and analyzed by using the statistics issues of Korean Maritime Safety Tribunal. Based on the analysis of most domestic marine accidents such as engine damage, collision, capsizing of small vessels, we propose how to use mobile telecommunication terminals for preventing marine accidents and the best countermeasures.
Comparative Studies of Evacuation Time According to the Distribution Characteristics of Training Ship's Personnels
Hwang, Kwang-Il ;
Journal of Navigation and Port Research, volume 35, issue 3, 2011, Pages 213~218
DOI : 10.5394/KINPR.2011.35.3.213
This study simulates and compares the evacuation time and characteristics according to the living patterns on board a training ship which was launched in Dec. 2005, on the viewpoint of the various activities being possible on board a cruise ship. Based on interviews with personnels on board, 3 living patterns are set as representative living conditions; Pattern A(all personnels are positioned at their cabins), Pattern B(all personnels are positioned at lecture rooms, offices or else), Pattern C(all personnels are positioned at restaurant or cafeteria). The simulation results show that Pattern B is comparatively ideal because the evacuation time is short and there is less delay of personnels' movement on each deck. On the contrary, Pattern C is evaluated as the worst because the average evacuation time took more than 360 seconds and the bottle-neck happened at Upper deck. As a result, this study proposes the needs of various countermeasures against the fire and/or disaster, considering the various living patterns on cruiser(s) and/or passenger ship(s).

Kim, Jung-Man ; Lee, Do-Hwa ;
Journal of Navigation and Port Research, volume 35, issue 3, 2011, Pages 219~226
DOI : 10.5394/KINPR.2011.35.3.219
This study aimed to empirically identify the determinants of turnover intention of seafarers under the recognition that the number of seamen is decreasing. The results of regression analyses on questionnaire survey data are as follows. The more satisfied over wage and working condition, the lower the level of turnover intention of seafarers. The higher social identification and career vision, the lower the level of turnover intention of seafarers. In addition to this, older, married seamen were found to have lower turnover intention as compared to younger, unmarried ones. Lastly, four-year college graduates were, on the other hand, found to have higher turnover intention.

DOI : 10.5394/KINPR.2011.35.3.227
This paper presents the tracking and stabilization problem of a night vision system for marine surveillance. Both a hardware system and software modules are developed to control azimuth and elevation axes independently with compensation for ship motion. A two degree of freedom(2DOF) PID controller is designed and its parameters are tuned using a real-coded genetic algorithm(RCGA). Simulation demonstrates the effectiveness of the proposed method.

Ha, Chang-Seung ; Kwak, Kyu-Seok ;
Journal of Navigation and Port Research, volume 35, issue 3, 2011, Pages 235~241
DOI : 10.5394/KINPR.2011.35.3.235
The shuttle that currently connects Busan New Port to the logistics companies in the Hinterland has the following companies: first, resources are consumed redundantly as each logistics company has independent transport vehicles. Second, the companies are not taking advantage of geographical merits of clustered complexes because different vehicles are used each time due to irregular schedules. In this respect, this study had the following purposes to realize these solutions: first, heuristic approach was made for operation scheduling and real-time operating rules to configure the best possible dynamic plan. Second, the reduction of consumption of resources with the shuttle and the efficiency were examined through a simulation of pooling and dual cycling applied to logistics companies' shipping plans.

The container ports have been increasingly changed according to the industry structure and differentiated customer's needs. So it seems to need the differentiated service strategies to have their competitiveness. To assess the customer requirements objectively, this paper associated the service process of container ports with the service quality scale by using the Quality Function Development(QFD). This paper analysed the service process of Busan port and then compared it with those of Shanghai port and Tokyo port which are the typical port of the northeast asia. Also, after drawing the importance of the service process as well as its priorities by representing the relation between service quality scale and processes of the container ports, this paper proposed the House of Quality(HOQ) for service quality improvements.

Kim, Sang-Goo ; Seong, Eun-Hye ;
Journal of Navigation and Port Research, volume 35, issue 3, 2011, Pages 253~258
DOI : 10.5394/KINPR.2011.35.3.253
This study aimed to analyze the effect of New University for Regional Innovation in terms of the users. The evaluation indicators based on the reports of NURI port logistics education project from 2005 to 2009 are overall satisfaction, detailed satisfaction, comparative advantage for from the other universities, continuous employment intention, necessity of re-education, and priority of educational needs and so on. And the percentage of employment was chosen from 2006 to 2009 for the more objective analysis. Analysis shows that the effect of the program is founded because the satisfaction increased gradually and the comparative advantage for from the other universities was higher and the necessity of re-education declined less and less. Especially the program filled the foreign language demands. But it needs to reinforce the links between schools and industries. And also the percentage of employment for the participated departments has continuously increased compared with that for non-participated departments, it shows that the effects of NURI project.

Lee, Ji-Hoon ; Hwang, Kwang-Il ;
Journal of Navigation and Port Research, volume 35, issue 3, 2011, Pages 265~270
DOI : 10.5394/KINPR.2011.35.3.265
The purpose of this study is to compare and analyze the differences of a building's heating and cooling loads depending on the weather variation. Followings are the results. The temperature, humidity and wind speeds of standard year are bigger than those of 2006~2009. The 2006~2009's total horizontal solar irradiance is greater than that of standard year, and the direct solar irradiance of standard year is bigger in winter and vice versa in summer. As results of simulation on heating and cooling loads, it is difficult to find out the bilateral influences between maximum thermal loads and annual's. The equivalent-time operating ratio(EOR) is defined on this study to estimate the differences between year and year, and the EOR of standard year shows low value comparing to 2006~2009 years'.
