In recent years, using a smart phone that can access the Internet becomes routine in society through development of information and communication technology. On land, as especially actual accidents and research results show risk that using the smart phone while driving at the same time, and there are traffic laws and regulations that restriction of using of smart phone. But the regulations on the use of smart phones at sea is incomplete state. On this paper. We invested present status of use and reality of smart phone at sea and analyzed the subjective risk for judging to apply to regulation. And we analyzed risk quantitatively by using the simulation experiment; it Suggested a direction of guideline for use of smart phone at sea.

The increasing trade volume between Korea and China has rapidly expanded the maritime transport between the two countries. However, safety, particularly considering the ship collisions in the Yellow Sea and East Sea waters, has not been fully ensured. These collision accidents in that region endanger traffic safety and the marine environment, moreover, it has the potential to cause legal complexity because Korea and China haver domestic legislation, that are considerably different in some aspects. International conventions and domestic legislation in China provide detailed laws with respect to ship collisions, however, the theory of ship collision infringement still needs to be improved, enriched, and developed. Because these laws are not very clear on the resolution of disputes resulting from ship collisions, we focused on the final judgments by the Supreme Court of China (SPC), and the judicial judgments set by the Maritime Court of China. This study aimed to explore the domestic legislation applicable to disputes related to ship collisions in China, and comparatively investigate the legal provisions of Korea and China on the issue of ship collisions, particularly on the aspect of damage compensation, fault ration, and liability apportionment.

Although navigation systems and automatic identification technologies are in use for nautical safety of ocean vessels, ship collisions are increasing due to the growing number of overseas transportations. Since these accidents are mostly caused by the watch officers and crews' human mistakes, it is essential to develop a new set of systems to prevent such misfortunes. Therefore, we suggest a control and management system which monitors crews in order to conduct secure on-board navigation and nautical safety. We also materialized a mobile terminal system and portable device for the crews to check the status of the ship, and we designed a platform for an integrated surveillance system to assure a harmless voyage. Lastly, we attested the mutual connections of integrated safety-related data.

Aids to Navigation (AtoN) are marine traffic facilities to improve the safety and efficiency of shipping. "New Dangers" should be appropriately marked using lateral, cardinal or isolated danger marks or by using an Emergency Wreck Marking Buoy. However, Emergency Wreck Marking Buoys are difficult to implement in terms of speed and accuracy of installation. In the case of sinking accidents, it is often difficult to immediately install an Emergency Wreck Marking Buoy because of weather conditions, the marine environment or accident positioning. This study concerns Auto-Releasing Emergency Wreck Marking Buoys, which should be installed in all vessel for safe marine navigation and efficient maritime transport with reference to the Maritime Buoyage System (MBS). Auto-Releasing Emergency Wreck Marking Buoys include an auto-release unit, auto reel chain and auto lighting lantern. These buoys can be automatically released from the deck of a vessel and will float in the water for quick installation at the scene of an accident, even in the case of sinking accidents. Auto-Releasing New Mark Buoys are expected to reduce to installation process, prevent secondary accidents by the risk of navigation and be search and rescue rapidly.

A variety of decarbonized energy sources are being developed globally to realize carbon neutrality (Net Zero) by 2050 as a measure to address the global climate crisis. As the Korean government has also established a Renewable Energy 3020 policy and promoted energy development plans using solar or wind power, large-scale offshore development projects not present before in coastal waters, such as offshore wind farms, are being promoted. From ships' point of view, offshore facilities present obstacles to safe navigation, and with the installation of marine facilities, ship collisions or contact accidents between ships and marine facilities may occur in the narrowed water areas. In addition, there are concerns about environmental pollution and human casualties caused by marine accidents. Accordingly, we review overseas and domestic offshore wind farm development plans, analyze whether institutional devices are in place to ensure the safe passage of ships in wind farm areas, and study the safe operation of large-scale offshore wind farms and safe passage of ships along the Korean coast by comparing overseas legislative cases with domestic laws and presenting a proposal to illuminate the legal blind sectors.

Ulsan Port is the biggest base port for liquid cargoes in Korea and is pushing in earnest for the development of the 'Ulsan New Port' and 'Northeast Asia Oil-Hub' to prepare for continuous shipment growth. However, Ulsan is in the situation which the harbour limit and anchorages are narrower than other trading ports and the occurrence probability of marine accidents is very high due to heavy marine traffic. We will find and suggest the plan to enlarge the harbour limit essentially needed to expand anchorages considering the geomorphological features of Ulsan and the volume of marine traffic in this research. For the enlargement of harbour limit needed to expand anchorages, the anchorage area needed for Ulsan New Port was calculated after the quantitative analysis of enlargement range through the mutual comparison of the area of harbour limit and anchorages with berths and the volume of marine traffic. The reasonable type of harbour limit, which is based on the survey by a group of experts, was also determined after the decision of the range of harbour limit to accommodate the relevant anchorages.

Many countries are developing transportation technologies aimed at reducing environmental pollution and the environmental burden. For example, environmentally friendly transportation routes and methods are being used to improve inland waterways in Europe. Against this backdrop, a case study was conducted on special cargo (weight cargo, earth and sand, etc.) on Korea's Gyeong-In Ara Waterway, an inland waterway connecting the Han River and the West Sea, serving a distribution function. The results of the analysis showed that coastal shipping could be promoted using the waterway, including a positive synergy among environmental, economic, and social aspects. That is, by shifting from overland transportation to marine transportation, it is possible to reduce environmental pollution, ease traffic congestion, decrease traffic accidents, and shorten the licensing period for the weight cargo demand of the northern area of the Han River. In this respect, the Gyeong-in Ara Waterway could become an environmentally friendly transportation route, promoting coastal shipping in Korea. However, for this to occur, support systems such as subsidies for marine transportation and using the inland waterway are required, as happens in the EU. Furthermore, existing policies to promote coastal shipping should be improved and applied more broadly.

Recently, vessel's average speed in the sea becomes fast because of the increasing of high-speeds vessel like a container ship and ferry. So, it is considered that speed control in the korean narrow waterway isn't the proper vessel traffic management, now. And, there is a rare paper studied about speed control quantitatively and numerically, especially speed control is discussing continuously, as abrogation of Incheon Port's speed control and alleviation of Kwangyang Port's speed control a according to navigating mariner's request. After this paper replayed the navigation traffic flow in the straight waterway using marine traffic flow simulation, the Environmental Stress Model is introduced to evaluate difficulty of each vessel's traffic.
