According to the increasing attention to safety and security in maritime shipping, there are diverse security systems in international logistics activities. Although prior studies on maritime transport and port security reviewed security policy and practices in order to provide useful insights for strategic agenda, a few focused on attitude to respond it. Moreover, there are no prior study on a comparative study between continents. To tackle this, this paper compared confrontation attitude to maritime transport and port security between South Korea and European Union. Results identified that maritime shipping security incorporates container cargo security management, logistics security management, logistics security certificate system, and environmental impacts management caused by maritime shipping. Further, the comparison between two countries suggests that South Korea need to take more positive attitude to respond, such as investment in equipment and technologies for maritime shipping security, construction of comprehensive management system, political supports for logistics security, and training and education for safety and security. The results provide useful insights for strategic review of security systems in South Korea, and to help strategic agenda for future improvement.

We show a new scheme and implementation of maritime data communication systems for GMDSS ship which performs e-Navigation and removes the functional limitation of those systems through comparing to service fee, call processing reliability, and bit rates of all of those systems within communication range at sea. We confirmed available each frequency band communication and application services at sea by experimental result with proposed new system, MF/HF band being useful to a short text message service, VHF band to 9600bps email service, Fleet Broadband Maritime Satellite system to one or more Mbps multimedia service each.

The aims of this study were to validate the Occupational Basic Competencies of Fisheries and Maritime High school. Fisheries & Maritime key competencies were defined as the abilities that include the essential knowledge, skills, attitude, and experiences required for the workforce on the fisheries and maritime job condition. This research collected preliminary data from 1,113 fisheries & maritime high school students. Data were analyzed to obtain reliability and validity analysis. The results of the study were as follows; First, fisheries & maritime key competencies were divided into 6 elements. Second, fisheries & maritime key competencies were consisted of marine vocational ethics, marine information capacity, marine elementary knowlegde, marine safety management skill, management & utilization of marine life and marine consciousness. Third, Cronbach-${\alpha}$ proves that the scale developed in the study is reliable. In consequence, the results of this study help to reconceptualize fisheries & maritime and apply the scale to measure students in high school settings.

Enhancing the performance of maritime wireless communication has been highlighted by the issue of cell planning in the sea area because of lack of an appropriate Propagation Loss Model (PLM). To resolve the cell planning issue in vast sea areas, it was essential to develop the (PLM) matching the intended sea area. However, there were considerable gaps between the prediction of legacy PLMs and field measurement in propagation loss and there was a need to develop the adjusted PLM (A-PLM). Therefore, cell planning was performed on this adjusted model, including modification of the base station's location, altitude, and antenna azimuth to meet the quality objectives. Furthermore, in order to verify the availability of the cell planning, Communication Service Quality Monitoring System (CS-QMS) was developed in the LTE-Maritime project to collect LTE signal quality information from the onboard equipment at regular intervals and to ensure that the service quality was high enough to satisfy the goals in each designated grid. As a result of verification, the success rate of RSRP was 95.7% for the intensive management zone (IMZ) and 96.4% for the interested zone (IZ), respectively.
