Mongolia is aiming at connect and expand global trade to third countries using Russia, China and East Asian ports. Also, trying to evolve infrastructure and super-frastructure in international maritime transportation. This paper presents maritime development trends in Mongolia and focuses on discussing the current situation of international maritime plan and points out some issues currently facing by the policy to develop promoting the country's maritime businesses. Finally, this paper presents some future directions for developing the maritime transportation in Mongolia.

Smart Maritime Autonomous Surface Ship(MASS) is aiming to provide eco-friendly smart maritime navigation service based on safety, reliability and efficiency for maritime safety and marine environment protection. In the future, it is expected to bring about a radical change across the marine industry such as marine, maritime, port, logistics, ship-building and so forth. Therefore, in this paper, policy priorities related to the introduction of MASS were identified, and response strategies for each industry were set up, and a policy plan for establishing a smart maritime logistics system covering shipping, port and shipbuilding fields was proposed.

The ratio of the mobility handicapped person is about 25.8% of the total population in Korea(MCT, 2006). In order to prepare for the enforcement of the "Transportation Services Improvement Act for the Mobility Handicapped People"(MCT, 2006), various equipments and installations should be developed to ensure appropriate safety level for the mobility handicapped persons in maritime transportation. While approximately 10 million people are using domestic passenger vessels annually, preferences for maritime transport is very low, especially for the mobility handicapped. This study reviewed a current status of the mobility handicapped person in domestic passenger ship and analysed the improvement plan for them. To investigate the current status of domestic passenger vessel usage by the mobility handicapped, to analysis the requirements for amenities necessary for the mobility handicapped and select the ones to be developed based on the investigated results and to do feasibility study of barrier-free ship.

Nowadays, the issue of maritime safety is an extremely important issue in the maritime industry and Human' Stress is one of the biggest causes of maritime accidents. The purpose of this study was to research and compare the risk marine accidents analysis methods and find the methods which used to analysis data of the human' stress and obtained the relationship between it and the risk of maritime accidents.

Recently, the navigation risk is increasing significantly with growing of vessels' volume and propelling marine facilities, water bridges and port development etc. As a result, Ministry of Land, Transport and Maritime Affairs enacted a new law called MSA(Maritime Safety Audit) as a comprehensive maritime traffic safety management scheme in order to ensure safety improvements from the early planning stage to post managing of the development which affect the maritime traffic environment. MSA as a tool for improving maritime traffic safety is a formal safety diagnosis assessment in the existing or future ship's fairway by an independent audit institute. It examines the potential hazards of maritime traffic safety about the port development, if necessary, and is to ensure the implementation of appropriate safety measures. The primary purpose of MSA is to identify potential risk elements affecting safe navigation. This paper is aimed to introduce the backgrounds, the necessity and efficiency of MSA and also to describe some technical standards and diagnostic procedures.

The International Maritime Organization (IMO) states that the recommended horizontal accuracy for coastal and offshore areas is 10 m, the Alert Limit (AL) is 25 m, the time to alert is 10 seconds, and the integrity risk (IR) is 10^-5 per three hours. For operations requiring high accuracy, such as tugs and pushers, icebreakers, and automated docking, the IMO dictates that a high level of positioning accuracy of less than one meter and a protection level of 0.25 meters (for automated docking) to 2.5 meters should be achieved. In this paper, we analyze a method of calculating the user-side protection level of the centimeter-level precision Global Navigation Satellite System (GNSS) that is being studied to provide augmentation information for the precision Positioning, Navigation and Timing (PNT) service. In addition, we analyze standardized integrity forms based on RTCM SC-134 to propose an integrity information form and generate a centimeter-level precise PNT service plan.

R-Mode is terrestrial based Global Navigation Satellite System (GNSS) backup radio navigation technology which used existing maritime information service infrastructure. It has advantages on reduce the cost and reutilize the frequency resource. In this paper, we propose a method to develop a medium-frequency (MF) band R-Mode transmitting station by utilizing the currently operating Differential GNSS (DGNSS) reference station infrastructure. To this end, the considerations for co-operating the DGNSS reference station and the MF R-Mode transmitting station are analyzed. In this process, we also analyze what is necessary to configure the communication system as a navigation system for range measurement. Based on the analysis result, MF R-Mode transmitting station system is designed and architecture is proposed. The developed system is installed in the field, and the performance evaluation results is presented.

The sea-communication fishing equipment installed on small vessels such as offshore fishing vessels is highly dependent on foreign products due to its high dependence on foreign products. From the perspective of domestication, the development of localization at the overseas level is underway, and we intend to demonstrate it by creating a dedicated testbed in order to secure track records. In this paper, we wanted to derive the testbed shape and design method through basic research for the design of the testbed.
