Since 2000, S. Korea is building yachts through government supported localization, cooperation between industry and educational organizations, or partnerships with foreign firms but the yacht building has yet only accomplished trial manufactured ships and one-time production. Because of a lack of mass production, the industry assesses the domestic technical skills to an average 50~60% of developed countries and its market share is less than 1% in the world. In addition, domestic marine equipment is heavily depending on imports and the industry is experiencing shortage of technology and experts, small-sized companies, insufficient industry and educational organizations' cooperation networks, inadequate legislation and policies, deficient domestic market vitalization, and scarce international information. Thus, this study focuses on the alternative plans to strengthen competitiveness and to cope with problems in the southeast marine leisure equipment industry.

This study is an attempt to look into the future role of the ROKN and to provide a strategic way forward with a special focus on naval strategic concept and force planning. To accomplish this goal, this research takes four sequential steps for analysis: 1) assessing the role and utility of naval power of ROKN since its foundation back in 1945; 2) forecasting features of various maritime threats to influence the security of Korea in the future directly or indirectly; 3) identifying the roles to be undertaken by future ROKN; and 4) recommending Korean way of naval force planning and the operational concept of naval power. This study seeks to show that ROKN needs comprehensive role to better serve the nation with respect to national security, national prosperity and development, and future battle-space management. To safeguard the national security of Korea, it suggests three roles: 1) national guard for the peaceful unification; 2) protector of the maritime sovereignty; and 3) suppressor to maritime threats. Three more roles are highlighted for national prosperity: 1) escort of the national economy; 2) guardian for national maritime activities; and 3) contributor to the world peace. These roles need to be closely connected with the role for the battle-space management. This paper addresses the need for a dramatic shift of the central operational domain from land to maritime in the future. This will eventually offer future ROKN a leading role for developing strategic concept and force planning rather than merely a supporting one. This study finally suggests 'balanced' strategy both in concept development and force planning. A balanced force planning is a 'must' rather than an 'option' when considering a division of function between Task Fleets and Area Fleets, constructing cutting-edge conventional forces such as Aegis destroyer, CVs, or submarines, and the mix of high-profile platform and low-profile when composing future fleets. A 'balance' is also needed in operational concept. The fleet should be prepared to fulfill its missions based on two different types of force operation i.e., coercive or cooperative application of the utility of naval force. The findings and recommendations of the study are relevant today, and will be increasingly important in the future to achieve various political goals required by enhancing the utility of naval power.

In recent, the ships of the Republic of Korea have been suffered from acts of piracy at the seas. With the increase of the threats from the acts of piracy and armed robbery against ships, some of the countries have dispatched their navy warships to the international waters and to carry out military operation against the pirates. However, the total eradication of the piracy has not been achieved due to the lack of international cooperation and the limitation of the international maritime convention itself. In addition, the absence of counter-measures to be taken by the ships itself including the employment of the professional maritime security forces should not be overlooked. In this connection, this paper examined the reality of the piracy together with armed robberies at the seas and the problems in the response were also analyzed. Based on the research, it suggested some possible measures with special reference to the private security. The limitation of this paper is that it only focus on the aspect of the private security. In this paper, the cooperation among the countries according to the maritime convention and internationally accepted norms and practices. To achieve the goals of this paper, through the comparative review of the related literatures, the practical measures applicable to the prevention of the piracy were suggested.

A suction bucket foundation, especially useful at depths of more than 20m, is a method of construction. The method first places an empty upturned bucket at the target site. Then, the bucket is installed by sucking water or air into it to create negative pressure. For stability, it is crucial to secure the verticality of the bucket. However, inclination by the bucket may occur due to sea-bottom conditions. In general, a repeated intrusion-pulling method is used for securing verticality. However, it takes a long time to complete the job. In this paper, we propose a real-time suction bucket verticality monitoring system. Specifically, the system consists of a sensor unit that collects raw verticality data, a controller that processes the data and wirelessly transmits the information, and a display unit that shows verticality information of a circular steel pipe. The system is implemented using an inclination sensor and an embedded controller. Experimental results show that the proposed system can efficiently measure roll/pitch information with a 0.028% margin of error. Furthermore, we show that the system properly operates in a suction bucket-based model experiment.

The need for analysis of the operational efficiency and productivity of the Busan Port Container Terminal is increasing because of the Hanjin Shipping's bankruptcy and the re-establishment of the Maritime Alliance. This paper analyzes the efficiency and productivity of five Busan New Port Container Terminal companies by using the DEA analysis and Malmquist productivity index model based on the port construction disclosure data and the collected terminal internal data. According to the analysis, the average efficiency of the five container terminals increased in 2018 but declined slightly in 2019, and the Malmquist index showed that all terminals except A have advanced productivity. Additionally, relative to facility productivity, operators at the North Container Terminal had higher facility productivity than operators at the Busan New Port Nam Container Terminal, and regarding capital productivity, the D terminal ported by HMM, a national shipping company, was the highest in facility productivity. Regarding labor productivity, the C terminal showed the highest productivity, and regarding ship work productivity, the A terminal showed the highest productivity.

The aim of this study was to assess visible implant fluorescent elastomer (VIE) tagging and stress response in marine medaka, Oryzias dancena. The experimental fish were anesthetized individually and marked with red, yellow, or green elastomer at each of the following three body locations: (1) the abdomen, (2) the back, and (3) the caudal vasculature. During 12 months, the accumulated survival rates of fish in the experimental treatments were not different among red, yellow, and green elastomers. The experimental fish retained > 85% of the tags injected in the back, > 70% of the tags injected in the caudal vasculature, and > 60% of the tags injected in the abdomen (P < 0.05). An important observation was that the abdomen site was associated with poor tag retention. For all injected sites, the red and green tags were able to be detected more easily than the yellow tags when observed under both visible and UV lights. Tag readability was lower for the abdomen site than for the other sites (back and caudal vasculature). Thus, VIE tags were easy to apply to marine medaka (< 1 min per fish) and were readily visible when viewed under UV light.

The purpose of this study was to confirm that the formation and influencing factors of ocean governance in Busan. Recently it has been observed that the concept of ocean governance increasingly popular in the field of maritime administration, as the concept helps us understand more comprehensively the new or emerging roles of the government and other stakeholders(private enterprise, citizen, etc) in a rapidly changing environments. Therefore, this study aims to investigate the status of ocean governance and draw alternatives in applying appropriate ocean governance structure of maritime administration in Busan. The result of this study shows that ocean governance level in Busan was not high in some factors such as participation, cooperation, collective decision making. This is caused by the lack of a ocean governance structure. Based on these significant research findings, theoretical and practical implications were discussed.

Today, all the countries of the world newly recognize importance of sea, which are focused on efforts for security of marine territory and fishes resources. Many of the coastal state, to strengthen the rights of their own country EEZ, marine survey and continental shelf development, travels through such maritime jurisdiction in the territorial sovereignty and the EEZ overlaps, deepening complex interests between neighboring countries cooperation activities of the fierce competition, the domestic and foreign been has been carried out. Under such circumstances, is devastated coastal of China, our territorial waters and EEZ has been violated more and more, in spite of the powerful crackdown maritime public power, illegal fishing more resistance intensified. They tend to be gradually organization, collectivization and atrocities. Currently, illegal fishing of Chinese fishing boats in the West Sea of Korea, including the waters near Yeonpyeong Island is prevalent as operating in the coast of the country. Furthermore regrettable one is illegal on a scale and the situation where South Korea of scale of damage caused by it have not been accurately grasp of the operation, but that there is damage of Korea official duty enforcement to crack down the increase to illegal operations year after year have occurred. Violent, illegal fishing of Chinese fishing boats, in order to eradicate the operations of insane at our sea, we investigated to the infringement situations of fisheries resources by multiple fields. each of problems presenting a specific preservation plan in accordance with the function and role of the maritime enforcement organization and other government organization the point. at the same time we will try to seek measures such as a scheme that it is possible to increase the capacity.

This study aimed to review the reorganization of fisheries and the future tasks in accordance with the establishment of new fishery order in the Northeast Asian Seas. As the United Nations Convention on the Law of the Sea, which recognized the sovereign rights of Coastal States in a 200-nautical mile exclusive economic zone (EEZ), entered into force in 1994, the three countries of Korea, China and Japan ratified the United Nations Convention on the Law of the Sea in 1996 and started negotiations to establish a new fishery order consistent with the EEZ system. However, a conflict of interest occurred because of differences in fisheries between countries, negotiations many times have proceeded, resulting in the signing of fishery agreement between China and Japan in 1997, Korea and Japan in 1998, and Korea and China in 2000. Each fishery arrangement consists of a dual system of EEZ and provisional waters (middle waters, provisional waters). The two countries are engaged in mutual fishing based on coastal states in EEZ, and in the fishing operation under the principle of flag state in provisional waters. There are overlapping or ambiguous jurisdictions in the intermediate waters and provisional waters that are jointly available to both fisheries. The presence of these seas is a challenge to the establishment of a reasonable international fisheries management system for the entire Northeast Asian Seas. In this context, the challenges of the reorganization of the new fisheries order are as follows: 1) conversion to a fishery order for coexistence of fisheries, 2) expansion to an international fishery management system, and 3) establishment of a multilateral fishery cooperation system. Although the jurisdiction of their own waters has been expanded through the establishment of EEZ according to new fishery order, the need for mutual cooperation grows when considering the movement and migration of fishery resources, fishery management, fish consumption and trade. In addition to the fisheries cooperation between the governments, it is also necessary to revitalize the civil cooperation focused on fishermen who exploit fishing grounds together.
