Digital TV broadcasting's resolution or tone quality is very excellent than analog broadcasting and has many advantages including various multimedia functions such as home shopping, home banking, internet search, telecommuting, VOD, etc. In this study, it is essential to analyze the regional electromagnetic environment before Digital TV broadcasting, and therefore we analyzed Busan area's limitation using ETRI propagation model. For maintaining high-quality Digital TV signals, we measure electric field intensity wide and far in Busan including mountains area and high-rise buildings. Generally, it has lower value by a standard ETRI propagation model than simulated value about standard model, but distribution pattern are similar with it. Compared theoretical values with the measured results, they have similar values for flat area but very different values for crowded city area and mountains area So we conclude that ETRI propagation model and theoretical model are not suitable for Busan in a free space.

This paper attempts to examine the effect of EXPO 2012 Yeosu on the economy of Gwangyang bay area. Based on previous successful EXPOs, We identified four major positive effects (direct economic impact, regional infrastructure developments, redevelopment of slum areas and industrial complex, and internationalization of Gwangyang bay area). Especially, EXPO 2012 Yeosu will contribute to make the job creation of 97,842 employees and promote tourism industry. To maximize the above positive effects of EXPO 2012 Yeosu, we suggest several strategic alternatives in this paper. First of all, we need to make several plans for realizing the specialized theme of EXPO 2012 Yeosu. Second, local governments should create a more favorable business environment for foreign investors. Third, we have to make the strategic tourism programs to attract foreign tourists. Finally, local governments need to make the several communication strategies of utilizing mass media and non-mass media.

Piracy is the enemy of the human race. Pirates commit acts of murder, robbery, plunder or other villainous deeds at sea, cruelly against humanity. The Republic of Korea(ROK), as a big maritime country, is obliged to suppress piracy under international treaties it ratified, including the UN Convention on the Law of the Sea and the two 1988 Conventions against maritime terrorism The Korean government is recently taking a positive attitude towards the regional cooperation which is necessary for the suppression of piracy in the waters of Southeast Asia In spite of the effects of international cooperation to prevent piracy, it is recently on an increasing trend every year. Such circumstances may have a bad effect on the sound development of world economy by means of trade at sea as well as treat to the safety of crews and safe operation of ships. This paper aims to suggest the countermeasures against piracy in terms of criminal law, civil law and international law in order to secure safe operation of vessels at sea.

The purpose of this study is to examine the main features of South Korea's New Northern Policy and to make some suggestions for cooperation with neighboring countries' initiatives. The New Northern Policy encompasses the whole of Eurasia, but the starting development area would be the border region of the Korean Peninsula. In this viewpoint, this study examines the Belt and Road Initiative of China, the New Eastern Policy of Russia and the Steppe Road Initiative of Mongolia, and presents the characteristics, problems and some implementation strategies of the New Northern Policy. Apart from the future possibilities of the regional cooperations that include North Korea, it would be necessary for South Korea to secure and expand the possible opportunities for "Korea-China-Mongolia-Russia" cooperation. In order to create a close cooperative environment with North Korea in the future, it would also be necessary to build a maritime route, with port development around major border regions on the Korean Peninsula, including Russia, and to develop the port-railway intermodal transportation system with neighboring countries. South Korea need to actively cooperate with neighboring countries to develop the new Eurasia logistics routes would be more favorable to the Korean Peninsula in preparation for the time when the North Korean nuclear issue will be resolved.

Marine accidents and legal violations result from mistakes and negligences of ship officers, deck officers and engine officers, during the ship navigation and lay days. Due to these accidents and violations, these officers are subjected to disciplinary actions for certification. The disciplinary action, namely certificate punishment is carried out by right rules, processes and equity. However, it is revealed that present situations are different from the principles. For the purpose of finding current states relating to certificate punishment, this study examines and analyses 737 punishment cases, accomplished in 'B' regional office of oceans & fisheries for 5 years from 2014 to 2018. The contents to be analyzed are reprimand agencies, certificate kinds, officers ranks at that time, disciplinary level, violated acts, annual reprimand state, punishment rule and it process, and disciplinary reduction levels. From such valuations various problems, such as disciplinary level deviations among laws, insufficient punishments rules, disciplinary certificate deviation, insufficient reprimand reduction rules, and lack function of crew administrative disciplinary council, are identified. Finally, methods to alleviate the problems identified will be proposed. This study, for the first time analyses the actual administrative disciplinary cases for ship officers'certificates and proposes improvement plans for its incorporation in Korea, This analysis will be useful in the examination of the study for the ship officers and making a plan for them.

Aids to Navigation(AtoN) Accident can reduce the credibility of AtoN by adding extra works to the administrators, and cause burdens and inconveniences to the users during their navigation leading to social costs (or economic losses). Prior research on social cost estimation model to determine the Encounter cost, Administrative cost and Risk cost on the Aton model was done to estimate the economic losses due to AtoN Accident. However, this research could not provide adequate study results on risk cost estimates. Therefore, this study complements the estimation model presented in the previous study, and the estimated social cost of 249 AtoN Accidents that occurred during the last 10 years (2008-2017) in the Busan Regional Office of Oceans and Fisheries jurisdiction area. The risk cost was estimated using contingent valuation method since the AtoN is a non-market goods. As a result, the social cost of AtoN Accidents for the past 10 years was estimated to total 12.4 billion won including Encounter cost of 3.1 billion won (25.38%), Administrative cost of 1.7 billion won (13.62%), and Risk cost of 7.5 billion won (61.01%).

In the Northeast Asian region, including Korea, China, and Japan, with rapid economic growth since the 1990s, intra-regional oil logistics has been increasing. Under such external circumstances, Korea has been pursuing a policy to become a Northeast Asian petroleum logistics hub since the mid-2000s. In order to become a Northeast Asian logistics hub, it is important to establish and promote a business model to promote the value-added oil logistics business. This study aims to propose policies and practical implications for increasing petroleum logistics by analyzing Korea's petroleum logistics business model in Northeast Asia. The results of case analysis through interviews with 23 tank terminal companies are as follows. First, most of the oil storage tank terminal companies interviewed are conducting value-added petroleum logistics such as blending, breaking bulk, and consolidation etc. Second, value-added petroleum logistics is caused by an imbalance in supply and demand among neighboring countries in Northeast Asia. In particular, there is a high demand for breaking bulk and blending connecting Japan, Oceania, the United States, and South America. Third, it is necessary to promote the promotion of value-added logistics by improving infrastructure, institutions, and regulations in response to the demand for value-added petroleum logistics, which will greatly contribute to Korea's policy for being Northeast Asian oil hub.
