An, Kwang ; Kim, Inchul ; Kim, Chol-Seong ;
Journal of the Korean Society of Marine Environment & Safety, volume 22, issue 4, 2016, Pages 305~310
DOI : 10.7837/kosomes.2016.22.4.305
This study identified necessary navigational support services to prevent accidents through an examination and a survey on the navigation and communication systems of non-SOLAS ships. The functional and operational requirements for the identified navigational support services were discussed accordingly. Among the navigational support services proposed are an Electronic Navigational Chart (ENC) service, a route planning service, an operation monitoring service, and collision prevention support services for ships in coastal areas. To facilitate the identified navigational support services, ship navigation system, shore supporting centre and maritime communication network were discussed as a digital infrastructure. The operational methode for the digital infrastructure were discussed in the service scenarios for ships carrying dangerous cargo, large ships over 200 meters in length and high speed passenger ships over 15 knots in speed. This study will facilitate the development of policies for the improvement of ship operation management in Korean coastal waters and will contribute to improving the navigational safety of non-SOLAS ships.

The VTS concept was located as a principal methods of maritime safety administration in world's major harbors and expected to become the pivotal role for the future of the maritime and harbor society with e-Navigation epoch. If recent limelight concept of big-data has been included in aspect of information gathering and analysis with various studies, it's required advanced studies to improve the information analysis capability and application range of the data that can be mining by the VTS. In this study, contrast to other studies that aimed quantitative analysis as communication number, it can be mining the time information and each of the communication VTS for the target vessel, including qualitative analysis, such as the purpose or the type of communication. This comparison across multiple items of the collected information, and presenting the VTS data mining model (VCDF) that can be analyzed for the purpose of analyzing way, type and number of communication by ship's type, also number of violations through VTS communication. First, In Busan port case, it shows frequently information service and shows frequently communicating with particular types of vessels. Second, Passive VTS carried out notwithstanding many kinds of traffic violations due to communication congestion. This arranged information can be used as data for the analysis, as possible the level of traffic for VTSO situational awareness, which pointed to the 'workloads' in 'IALA Guideline' and could be used as a database for future research of e-Navigation.

Whereas shipping and Ship-building industries of Korea have been under the direct influence of International Maritime Organization (IMO) conventions and resolutions that aim at maritime safety and the protection of marine environment, it is needed that a specialized institute for dealing with IMO Agenda be established by industry-academy-government collaboration. Accordingly, this study proposes the establishment of a specialized institute to manage the IMO Agenda. To this end, integrating the existing bodies and their functions into a specialized institute, namely, the International Maritime Cooperation Center, is suggested. This center, composed of 40 researchers and operated by the Korea Maritime Institute, could assume this role. This study proceeds by building an estimate of the operational cost of the institute and exploring practical ways to finance it through the private and public sectors, also considering revisions to the Maritime Safety Act to ensure continuous operation of the new institute.

The everyday life of police officers requires them to face a number of criminal acts and enter compromising crime scenes. In this case, officers may be compelled to make a personal expression of negative emotions. Negative emotions of members confidence for effective job processing and contributions duties and achievement of the job within the marine police force. Therefore, to control the emotive dissonance of organization members is a great help to the development of the organization. This study focuses on emotional dissonance among marine police officers to verify the impact of this dissonance on job burnout and consider the mediating effect of emotional intelligence. Research results are as follows: First, the relationship between emotional dissonance sub-factors and job burnout among marine police officers was studied. It was found that marine police did not feel emotionally jarred because they consciously tried to abstain from emotional engagement, but this was found to reduce emotional intelligence as related to desired emotions as well. Second, Emotional intelligence of the Marine Police was found on a significant impact on job burnout. Third, the impact of emotions in relation to emotional dissonance that job burnout of marine police intelligence officials confirmed that there is a statistically significant mediating effect. Finally, in a comparison of direct effects versus mediated effects, marine police were seen to be prone to emotional dissonance and experienced job burnout as a direct result of applying greater emotional intelligence.
A Study of Distribution of Jellyfish by Particle Numerical Experiment in Masan Bay
Choi, Min-Ho ; Ryu, Tai-Gwan ; Kim, Dong-Sun ;
Journal of the Korean Society of Marine Environment & Safety, volume 22, issue 4, 2016, Pages 335~343
DOI : 10.7837/kosomes.2016.22.4.335
The spatio-temporal distribution of jellyfish in Masan Bay was investigated in this study using a numerical model. First, a three-dimensional hydrodynamic model (POM) was constructed,taking into account residual flows, tides, temperature, salinity, and wind effects. A particle tracking model based on residual flow was then used to investigate the jellyfish present in Masan Port, referred to as the Heavy Industry and Gapo New Port in Masan. Jellyfish distribution was concentrated with maximum (2,533 individual) in the North Sea near Machang Bridge. Itcan be concluded that this concentration was due to multi-directional residual flows and topography effects. Residual flow currents are a dominant factor in understanding the aggregation of jellyfish, and this study used a numerical simulation of tide-induced residual currents, wind-driven currents and density currents in distinct cases to thoroughly address the topic. As a result, wind-driven currents (effect of the wind) was found to be superior to other components as an influence on the distribution of jellyfish near Machang Bridge and Modo in Masan Bay.

Kim, Ho-Kyun ; Kim, Young Taeg ; Lee, Dong Hwan ;
Journal of the Korean Society of Marine Environment & Safety, volume 22, issue 4, 2016, Pages 344~353
DOI : 10.7837/kosomes.2016.22.4.344
The cause of abnormal tidal residuals was examined by analyzing sea levels, sea surface atmospheric pressures, winds at ten tide stations, and current, measured at the coast of the Yellow Sea from the night of November
to the morning of the
in 2013, along with weather chart. Additionally, the cross-correlations among the measured data were also examined. The 'abnormal tidal residuals' mentioned in this study refer to differences between maximum and minium tidal residuals. The largest abnormal tidal residual was identified to be a difference of 176 cm occurring over 4 hours and 1 minute at YeongJongDo (YJD) with a maximum tidal residual of 111 cm and minimum of -65 cm. The smallest abnormal tidal residual was 68 cm at MoSeulPo (MSP) during 8 hours 52 minutes. The cause of these abnormal tidal residuals was not a meteo-tsunami generated by an atmospheric pressure jump but wind generated by the pressure patterns. The flow speed due to these abnormal tidal residuals as measured at ten tide stations was not negligible, representing 16 ~ 41 % of the annual average ebb current speed. From the cross correlation among the tidal residuals, winds, and tidal residual currents, we learned the northern flow, due to southerly winds, raised the sea level at Incheon when a low pressure center located on the left side of the Korean Peninsula. After passing the Korean Peninsula, a southern flow due to northerly winds decreased the sea level.

While the amounts of oil spill caused by the VLCC Hebei Spirit indicated 2.5 times more than that of the VLCC Sea Prince, the economic, environmental, and social damages derived from the Hebei Spirit spill were estimated to be about 30 times greater than those from the Sea Prince incident. This study consolidates the appropriate justification for building a multi-purpose large oil spill response vessel to allow swift and efficient handling of catastrophic marine pollution events through an analysis of technical and economic feasibility of such a project. The result of the technical feasibility analysis illustrates that a hopper dredge and oil spill response vessel with a capacity of 4,000 tons should be more appropriate. The result of the economic feasibility analysis indicates that under the most conservative estimates the project appears to be slightly impractical, with a benefit/cost ratio of 0.82, in which self-help efforts, however, can facilitate the project. And medium to optimistic estimates present benefit/cost ratios are estimated to be 2.72 and 5.82 respectively, representing apparent economic feasibility.
The Variability of CDOM Along the Salinity Gradients of the Seomjin River Estuary During Dry and Wet Seasons
Lee, Jae Hwan ; Park, Mi Ok ;
Journal of the Korean Society of Marine Environment & Safety, volume 22, issue 4, 2016, Pages 362~371
DOI : 10.7837/kosomes.2016.22.4.362
The distribution patterns of Chromophoric Dissolved Organic Matter (CDOM) and the chemical characteristics of CDOM in the Seomjin river estuary were investigated in March, June and July 2012 in order to determine the spatial and temporal variability of CDOM along the salinity gradient considering the effects of mixing, nutrients and Chl a. The average CDOM values were
in March, June and July, respectively. A high concentration of CDOM (greater than
) was found at the head of the river which decreased towards the river mouth to as low as less than
. The average concentrations of CDOM increased from the dry season (March and June) to the wet season (July), and the average slope values (
), which were used as indicators of CDOM characteristics and sources, were in the range of
. The CDOM and
values showed that not only the concentration of CDOM but also the chemical properties of DOM clearly changed between upstream and downstream in the Seomjin river. CDOM and FDOM showed a negative correlation with salinity (
> 0.8), and CDOM was positively correlated with FDOM. Furthermore, the mixing pattern of CDOM was confirmed as conservative for all seasons. The main environmental factors influencing the concentration of CDOM was confirmed as conservative for all seasons. The main environmental factors influencing the concentration of CDOM were salinity (mixing) and water temperature, which meant the dilution of low CDOM seawater, was the controlling factor for the spatial distribution of CDOM. Increases in water temperature seemed to induce the production of CDOM during summer (June and July) through the biological degradation of DOM either by microbial activity or photo-degradation.
