Ocean Literacy is an understanding of the ocean's influence on you and your influence on the ocean. This research developed the 7 ocean education model courses using ocean literacy based on the analysis of ocean education programs which executed 23 agencies in Busan. These model courses are combined in the type of indoor theory, indoor experience, field study and field experience. Also, this makes the guide map for ocean education in a 76cm*56cm size to distinguish and choose the course easily. This map is the format combined in geological location and tourist attraction spots in Busan, includes education centers, contents, lead time and so on, and it is possible for educatees to handle their preference and seasonality elastically. This map including ocean education model course is a milestone to activate ocean education, and is helpful to reach the goal of ocean education and to lead ocean professionals. In addition, this research presents the development of teaching materials, training aids to complement the weakness of indoor education, the development of cyber education through making video contents as the activation measures of ocean education.

The objective of this study is to examine the nonlinear fluid characteristics near and inside a moonpool in various sea conditions. We estimate the flow of the free surface in a moonpool taking into account the viscosity effect and the hydrodynamic forces that affects a moonpool and hull through CFD calculations. The comparison of horizontal forces per wave length shows that the hydrodynamic force is greater for the long wave length than short wave length, and the greatest hydrodynamic force acts on the moonpool when the wave length is equal to the ship's length. The horizontal force decreases as the wave amplitude decreases, and the hydrodynamic force acting on the moonpool in
is 10 times that in
. The free surface demonstrates the piston mode, in which it oscillates up and down while remaining essentially flat, and the rise of the free surface level increases as the wave length increases. We can assume that the hydrodynamic force acting on the moonpool increases owing to the effect of a strong vortex for
and owing to the rise of the free surface level for

Lab scale experiment was carried out to study biological wastewater treatment technology developed for shipboard. RCM process using BM(Beneficial Microorganisms) was investigated for practical application on shipboard sewage treatment. RCM process is an environmental friendly treatment system, with minimum production of sludge. In the test, BOD5, CODcr, T-N and T-P were reduced a 96%, 97%, 78% and 81.68% respectively. From the result it was suggested that RCM process with BM might be a suitable process for shipboard sewage treatment, maintenance of useful microorganisms and creating special environment as the SDC tank is circulating in the non-biodegradable organics sludge generated during the wastewater treatment, thus reducing the amount of sludge generated. Therefore, the RCM process does not require additional equipment to strengthen it to meet the marine pollution standards.
A Vector-based Azimuth Algorithm using Indoor-Positioning Systems for Mobile Nodes
Son, Joo-Young ;
Journal of Navigation and Port Research, volume 38, issue 5, 2014, Pages 457~462
DOI : 10.5394/KINPR.2014.38.5.457
Indoor-positioning systems are useful to various applications. Navigation system is one of the most popular applications, which needs the information of directions of nodes' movements. Specifically the applications should get the information in real-time to properly show the current moving position of a node. In this paper, simple vector-based algorithms are proposed to compute amount and direction of changes of azimuth of mobile nodes' heading directions using existing indoor positioning systems in indoor environments where azimuth sensors do not work properly. Previous algorithms calculate the azimuth changes by too many steps of topology-based formula. The algorithms proposed in this paper get the amount of changes of azimuth by simple formula based on vector, and determine the direction of changes by the sign of value of simple formula based on the previous movement of nodes. The algorithms are much simpler and less error-prone than previous ones, and then they can detect changes in many location-based applications as well. The performance of the algorithms is proved logically and mathematically.

Nam, Taek-Kun ; Jung, Chang-Hyun ; Kim, Jin-Man ; Choi, Hyuek-Jin ;
Journal of Navigation and Port Research, volume 38, issue 5, 2014, Pages 463~470
DOI : 10.5394/KINPR.2014.38.5.463
In this paper, calculation of towing force required to tow the ship and experiments to verify its appropriacy are discussed. Friction, wind and wave-making resistance of vessel are considered to calculate towing force of specified vessel. Propeller resistance is also reflected and it is assumed that the propellers are locked. Node analysis to estimate additional resistance on towline is applied. Total towing force could be obtained by adding the ship's resistance and towline resistance. Experiments with training ship SAE YU DAL was executed to check the effectiveness of calculation methods and some comparison between experiments and calculation results was also done. From the comparative analysis, we confirmed that towing speed is primary terms in the calculation of towing force and propeller resistance is a major elements of ship's resistance with the increasing of towing speed. We can see that additional resistance induced by yawing of ship during towing have to be considered for total tow resistance.
A study on Problems of Charterparty for Tug & barge Ship which Employed in Marine Construction and its Systematic Improvement Plan
Jang, Yeong-Jun ;

In general, a regular charterparty form is used as a charterparty for tugboats which are employed in marine construction and a bareboat charter form is generally used for barge boat charterparty. As the tug-barge charterparty which are currently used do not have a standardised form, contracting parties arbitrarily decide on the terms and conditions of the contract. As a result, provisions of the charterparty usually do not specify in the contract which party bears the burden of liability in case of accident. Furthermore, the terminologies used in the charterparty are different from legal terms of current commercial law which causes confusion. These problems can be solved mostly by clarifying the legal character of the charterparty between the contracting parties and by conforming the terminologies. In addition, endeavour to standardise the contract form must be carried forward at the same time. This research purports to study actual condition of current charterparty for tug-barge ship which are employed to marine construction and to suggest systematic improvement plan. For this purpose, this research focuses on studying cases in which dispute arose due to lack of clarity in the provisions of the contract with regard to which party bears the burden of liability in case of accident. This research also purports to suggest forming the standardised contract terms of the charterparty as one way of solution and examine matters to be attended in writing a standardised form.

Yang, Won-Jae ;
Journal of Navigation and Port Research, volume 38, issue 5, 2014, Pages 479~484
DOI : 10.5394/KINPR.2014.38.5.479
This paper presents the crew members fatigue survey in order to understand the current state of various fatigue causal factors and personnel fatigue subjective symptoms, and then analyzes the survey items. The results of this survey are as follows. Firstly, many crew members were struggling with the lack of sleep and rest hour. Secondly, environmental factors such as weather, ship motion and vibration, noise, accommodation condition etc. disturbed the sleep of crew members. In third, their duty hours were more than 10 hours per day in certain types of ship. In fourth, they felt fatigue a lot when they were on board because of the workload and stress. Lastly, in some measurement items of fatigue symptoms(physical, mental, emotional), many crew members were experiencing more than moderate fatigue symptoms.
Study on Simulator Sickness Measure on Scene Movement Based Ship Handing Simulator Using SSQ and COP
Fang, Tae-Hyun ; Jang, Jun-Hyuk ; Oh, Seung-Bin ; Kim, Hong-Tae ;
Journal of Navigation and Port Research, volume 38, issue 5, 2014, Pages 485~491
DOI : 10.5394/KINPR.2014.38.5.485
In this paper, it is proposed that the effects of simulator sickness due to scene movement in ship handling simulator can be measured by using center of pressure (COP) and a simulator sickness questionnaire (SSQ). For experiments of simulator sickness, twelve participants are exposed to scenes movement from ship handling simulator according to three steps of sea states. During experiments, COPs for subjects are measured by force plate. After exposure to scenes movement, subjects describe their sickness symptoms by answering the SSQ. Throughput analysing the results of scene movement, SSQ, and COP, the relation between the simulator sickness and COP is investigated. It is suggested that formulations for SSQ score and COP with respect to sea state are obtained by the curve fitting technique, and the longitudinal COP can be used for measuring the simulator sickness.
Routing of ALVs under Uncertainty in Automated Container Terminals
Kim, Jeongmin ; Lee, Donggyun ; Ryu, Kwang Ryel ;
Journal of Navigation and Port Research, volume 38, issue 5, 2014, Pages 493~501
DOI : 10.5394/KINPR.2014.38.5.493
An automated lifting vehicle(ALV) used in an automated container terminal is a type of unmanned vehicle that can self-lift a container as well as self-transport it to a destination. To operate a fleet of ALVs efficiently, one needs to be able to determine a minimum-time route to a given destination whenever an ALV is to start its transport job. To find a route free from any collision or deadlock, the occupation time of the ALV on each segment of the route should be carefully scheduled to avoid any such hazard. However, it is not easy because not only the travel times of ALVs are uncertain due to traffic condition but also the operation times of cranes en route are not predicted precisely. In this paper, we propose a routing method based on an ant colony optimization algorithm that takes into account these uncertainties. The result of simulation experiment shows that the proposed method can effectively find good routes under uncertainty.
Numerical Analysis of Reflection Characteristics of Perforated Breakwater with a Resonant Channel
Kim, Jeong-Seok ; Seo, Ji-Hye ; Lee, Joong-Woo ; Park, Woo-Sun ;
Journal of Navigation and Port Research, volume 38, issue 5, 2014, Pages 503~509
DOI : 10.5394/KINPR.2014.38.5.503
In this study, a new concept perforated breakwater is proposed, which is having resonant channels. In the channel, perforated plate is installed for dissipating wave energy induced by flow separations. The breakwater has two advantages compared with conventional perforated breakwater having wave chamber with slotted walls. One is easy to control the target wave condition for dissipating wave energy, and the other is having the high structural safety because the structural members are not exposed to impact waves, directly. To evaluate wave reflection characteristics of the proposed breakwater, numerical experiment was carried out by using Galerkin's finite element model based on the linear potential theory. The results indicated that considerable energy dissipation occurs near the resonant period of channel, and wave reflection characteristics are affected by channel shape, location and opening ratio.

The history of the Korean lighthouse have been known to be begun from which installed by the purpose of the Japanese invasion of the outside. Modern navigational aid system have configured during the Japanese ruling era since the Incheon Palmido Lighthouse was built in 1903 as the first lighthouse in Korea. But in this regard it needs to be considered more carefully. Busan, as the city of international port and of Choryang Waegwan, had been a center of foreign relations between Korea and Japan since early 15th century. Because that reason, International port facility has been developed for a long time ago in Busan for example lighthouse, breakwater, wharf, jetty and so on. Nevertheless the lack of historical data and basic research related to the marine caused the proper history could not be established until now. In recently the basic translation of Korean Maritime Customs documents started to finish, and a compilation book of old pictorial maps on Choryang Waegwan was issued. As a result, more objective history of Busan Aids to Navigation can be investigated.

Kim, Gha-Ryong ; Yhang, Wii-Joo ;
Journal of Navigation and Port Research, volume 38, issue 5, 2014, Pages 519~525
DOI : 10.5394/KINPR.2014.38.5.519
The study was to investigate the effect of the environmental factor on the emotion and satisfaction at the waiting lounge of the Busan International Cruise Terminal. This study focus on tourist at the waiting area in the Busan International Cruise Terminal. The data was collected through self-administered questionnaires and the research performed to face-to-face interview. For data analysis, used SPSS 18.0 and AMOS 18.0 of a structural equation model. The results of the study were found as follows: first, the physical environmental factor of the lounge influenced on the positive emotion. Second, the social factor affected the positive emotion. Finally, emotion affected the positive satisfaction. This study suggested that environmental factor was totally affected by emotion and thus environmental management depended on an individual characteristics of the individual place. The port authority will need more efforts to make a better waiting lounge setting for higher tourist satisfaction.
A Study on the Effects of the Type of Mixed Manning and the Ratio of Foreign Crew, the Acceptance and Adaptation of Cross-Culture to the Group Cohesiveness, Job Satisfaction and Organizational Commitment in Ship Organizations
Heo, Ki-Young ; Kim, Jin-Pil ; Shin, Yong-John ;
Journal of Navigation and Port Research, volume 38, issue 5, 2014, Pages 527~539
DOI : 10.5394/KINPR.2014.38.5.527
This study establishes the research model and sets up the hypothesis in order to analyze the effect of the type of mixed manning and the ratio of foreign crew on the group cohesiveness, job satisfaction and organizational commitment in ship organizations and the moderating effect of the acceptance and adaptation of cross-culture. For statistical hypothesis testing, it conducts a questionnaire survey targeting mixed manning ships and examines empirically the inter-variables relation through the regression. The result of empirical research is that the group cohesiveness, job satisfaction and organizational commitment in the ship organization of Korean master(chief engineer) and foreign officers is higher than that of Korean master and officers. Moreover, it is found that the group cohesiveness of 31~50% foreign crew group is less than that of the others. However, There is no moderating effects of the acceptance and adaptation of cross-culture. Additionally, it demonstrates the higher job satisfaction and organizational commitment in the stronger cohesiveness groups. The finding suggests the rationale that shipping and ship management companies could raise the group cohesiveness, job satisfaction and organizational commitment by moderating the type of mixed manning and the ratio of foreign crew.

Busan was known firstly to the western world in the end of 18th century. When the Joseon opened a port under the western powers in the late 19th century, Busan was an important port. The increasing number of international ship exchange had magnified the harbor facility and the importance of lighthouses of Busan port. Busan maritime customs officer were in charge of installation and management of lighthouses. The operations of maritime customs became historical origin of Joseon changing from feudal society to modern nation. The majority of the documents from maritime customs was disappeared. So it was hard to know the exact history. But investigating documents and papers of Joseon, even media records will enable us to establish the objective fact relations. Moreover, published and translated data from the past make it possible such investigations. As a result, modern lighthouse of Busan harbor in the late Joseon after opening port was could be found. It could be offered to establishing the Korean modern history as the objective data.

The increasing demand of maritime transportation and port development especially due to increased international trade resulted in a strengthening of regulating the greenhouse gas emissions mainly from ships by International Maritime Organization (IMO). Responding to these international environmental regulation and enforcement, the United States and the European seaports have expanded their Green Port Policy, which can promote the public welfare by reducing pollution caused by ships and ports. Accordingly, in 2010, Korean government enacted "The Framework Act on Low Carbon, Green Growth" and had pushed for all Korean ports to establish and implement their own green port policies. Therefore, the objective of this study is to establish the Green Port Policy Plan for sustainable and environmental friendly operations and developments of Ulsan port, which plans to be the oil hub port of Northeast Asia. To this end, we studied the current status of the environmental policy issues in Ulsan Port and international-&-domestic case studies on establishment of green port policy. With these studies, Ulsan green policy alternatives were identified that through the experts advice, and then were prioritized by adopting AHP survey analysis. As the result of this study, it was notified that LED lights replacement and AMP establishment as the hardware policy and the port environmental management department as the software policy were equally important policy options for the implementation of sustainable Ulsan Green Port Policy to meet port's characteristics.
