Korea has disposed of medium and low level radioactive waste generated by operating nuclear power plants permanently through the radioactive waste repository located in Gyeongju. However, the maritime transport of radioactive waste is exposed to the risk of marine accidents, and it will be necessary to introduce a system to secure safety from the viewpoint of the function and role of the Korea Coast Guard. Especially, Korea is affected by large-scale marine accidents, such as the Hebei Spirit or Sewol accidents. From this point of view, we analyzed the current status of Korea radioactive waste shipping and examined the response systems of major foreign countries. As a result of examining major cases of accidents, we have operated an Emergency Towing Vessel (ETV) fleet centering on European countries in order to respond urgently to marine casualties that may have social, regional and international effects, such as accidents of similar nuclear material carriers and dangerous cargo ships. It proves a partial effect. Based on this, we propose the introduction of the Korean ETV System. In other words, it is necessary to respond to large-scale marine accidents that could lead to enormous environmental, property, and personal damage, such as marine accidents involving nuclear material ships, large oil tankers, and large passenger ships. For this, it seems necessary to introduce Korea ETV, which can carry out emergency towing, oil pollution control function, large - scale rescue equipment and manpower. This will lead to the enhancement of the Korea Coast Guard response to marine accidents, and will not miss the golden time of the initial response to the national disaster, which will help protect precious people, property and the environment.

To induce container cargos to Gunsan port, we should struggle on securing the quantity of goods transported from the competitive Jeonbuk and Chungcheong areas by reducing transportation expenses by land, and make an activating plan for the international exchange between Gunsan port and nearby ports in China. As a result, if the plan to induce container cargos to Gunsan port is activated, the regular liners will stop at Gusan port. So the new sea route will be opened so that consignors can ship cargos in the proper time. The consignors will use Gunsan port frequently because of the reduction of distribution expenses. To do so, for the first, many incentives should be implemented to attract container cargos. In addition, various facilities should be fully equipped and improved. This paper is to improve the problems for which consignors, the shipping lines and forwarders may feel uncomfortable when they use Gunsan port. According to the research on the actual condition, the biggest problem in Gunsan port is the depth of water. The management, relation system, infrastructure and information system of Gunsan port are also insufficient. Therefore, this paper will make an alternative plan to improve these problems and help the container cargos induce to Gunsan port.

Blockchain is being applied in various fields home and abroad and its application cases can be explained in the banking industry, public sector, e-Commerce, medical industry, distribution and supply chain management, copyright protection. As examined in the blockchain application cases, it is expected to establish blockchain that can secure safety through distributed ledger in trade transaction because blockchain is established and applied in various sectors of industries home and abroad. Parties concerned of trade transaction can secure visibility even in interrupted specific section when they provide it as a base for distributed ledger application in trade and establish trade transaction model by applying blockchain. In case of interrupted specific section by using distributed ledger, blockchain model of trade transaction needs to be formed to make it possible for parties concerned involved in trade transaction to secure visibility and real-time tracking. Additionally, management should be possible from the time of contract until payment, freight transfer to buyers through land, air and maritime transportation. Conclusions - In order to boost blockchain-based logistics/distribution industry, the government, institutionally, needs to back up adding legal plan of shipping, logistics and distribution, reviewing standardization of electronic switching system and coming up with blockchain-based industrial road maps. In addition, the government, technologically, has to support R&D for integration with other high technology, standardization of distribution industry's blockchain technology and manpower training to expand technology development.

Young Jong Grand Bridge is approach traffic road of New Inchon International Airport which covers hub airport function in northeast asia. The total span length of this bridge is $4,420{\cal}m$ and this main bridge type is, the first in the world, Double Deck Self Anchored Suspension Bridge, designed as double deck systems to be arranged by road and railroad. Approach bridges to be connected with main span also are composed double deck steel truss and steel box girder to consider a continuity with this span. Our company erected $1,375{\cal}m$(about 60,000tons) of double deck steel truss bridge type which is composed by 6 traffic lane on upper deck and 4 traffic lane and Double track railroad on lower deck. The original installation method of this bridge was planed to install about 75 meters bridge blocks to use floating crane, after temporary bent was constructed between permanent piers. But this method which had to construct many temporary bents in the sea had the matter that construction periods can become lengthen and construction cost can be risen. To overcome the uncertainty to ensure high qualify of bridge and economic project execution, our company developed new bridge erection method to assure both quality control and economic construction work. The new erection method which was developed by us was one that could transport and install long bridge block, $120{\cal}m$ unit at a time and that temporary bent was not required. We hope that this paper is used as technical data which will erect bridge in the western sea and others marine region.

Leasing is one of the main methods for Chinese airlines to introduce aircraft from overseas manufactures, and this method has been used for more than 30 years by Chinese airlines. Aircraft leasing in essence is a kind of financial transaction, through which lessors provide finance to lessees by means of the delivery of possession of the leased aircraft. At the time when China started to introduce aircraft through leasing some 30 years ago, the Chinese domestic laws were very insufficient to regulate these activities. Therefore, a construction process for the law of aircraft leasing was triggered then, and some fruit has been gained. By far, there are rules to adjust the aircraft activities in the aspects of contract, real right, default and bankruptcy remedies. However, as the improvement of any system must undergo a process of exploration, the law of aircraft leasing in China is still faced up with many challenges. Especially with the emergence and prosperous of domestic leasing industry, new transaction structures and models of aircraft leasing have emerged, which leaves new challenges to current legal system. On the basis of introducing the history and main contents of Chinese legal regime of aircraft leasing, this paper offers an analysis of achievements and challenges on present Chinese laws in the aspects of contract, real right and remedies.

Crude oil is a resource that is being used as a raw material in major industries, representing the price of the raw material market. It is also an important element that affects the shipping market in terms of fuel costs for freight vessels. As a result, crude oil and freight rates are closely related. Therefore, from January 2009 to June 2019, this study analyzed the dependency structure between oil price (WTI) and freight rates (BDI, BCI, BPI, BSI, and BHI) using daily data. The main results are summarized as follows. First, according to the copula results, survival Gumbel copula in WTI-BDI, Clayton copula in WTI-BCI, Survival Joe copula in WTI-BPI, Joe copula in WTI-BSI, and survival Gumbel copula in WTI-BHI were selected as the best-fitted model. Second, looking at Kendall's tau correlation, there is a positive correlation between BDI and oil price. Furthermore, freight rate index (BCI, BPI, BSI) and oil price show positive dependencies. In particular, the strongest dependence was found in BCI and oil price returns. However, BHI and oil price show a negative dependency. Third, looking at the tail-dependency structure, a pair between oil price and BDI, BCI showed a lower tail-dependency. The pair between oil price and BSI showed the upper tail-dependency.

The increased threat to commercial shipping by Somalia-based pirates has triggered an increased use of PMSC(Private Maritime Security Contractors). The use of PMSC to protect merchant ships against Somali-based piracy threat seems to have been most effective counter-piracy measures. However, there are various legal and practical questions around using PMSC and PCASP(Privately Contracted Armed Security Personnel) on board at sea. This paper aims to study the regulation and its problems of PMSC and PCASP on board to protect merchant ships against Somali-based piracy in the Indian Ocean and Gulf of Aden. In particular, this paper focuses on the legal issues including jurisdictional issues of PCASP on board merchant vessels, use of force by PCASP in self-defense, and authority for using PMSC. Currently, the legal framework relating to use of PMSC and PCASP on board protecting ships from Somali-based piracy is complex, sometimes ambiguous or inconsistent, and currently in a state of flux. Thus, this paper concludes that at this juncture an effort to coordinate this legal framework is necessary, as regards both the interpretation of existing rules related to PCASP on board merchant ships under UNCLOS(United Nations Convention on the Law of the Sea) and the creation of new rules. Also, this paper suggested that there is an urgent need to establish the PMSC-specific laws in Korea.

The present SOLAS Convention has maintained safety regulations in a largely prescriptive form and this has become overly prescriptive now. The prescriptive rules do not properly reflect technical advances and changing environments in the maritime sector in a timely manner. The purpose of this study is to provide preliminary research to lay a foundation for the development of a new regulatory framework based on safety performance which is not a prescriptive rule making bases. This study reviewed the concept and characteristics of a minimum requirement, the implications of safety regulations in terms of strategic, commercial and technical aspects, the compensative correlation between constructional requirements and operational measures, the concept of safety with regard to final stage confirmation of functions, expansion of implementers and objects of safety regulations, and the balance between safety and environmental protection requirements. Based on these research, 10 principles for the rule formulation process has been suggested such as consideration on the hardware requirements and software requirement, the multi-stage approval concept, new safety concerns for complex shipboard systems, considerations on the human element, regulatory impact assessments and measures to reduce administrative burdens.

In late 2010, the Korea Hydrographic and Oceanographic Administration proposed a national monitoring project involving the deployment of 8 realtime ocean data buoys. The area occupied by the buoy-array, located south of the Ieodo Ocean Research Station, can be regarded as a kind of gateway to Korean waters with respect to warm currents and the shipping industry. The acronym for the project, KOGA (Korea Ocean Gate Array) was derived from this aspect. To ensure the success of the project, international cooperation with the neighboring countries of China and Japan is highly desirable. Once KOGA is successfully launched and the moored buoys start to produce data, the data will be applied to various areas such as data assimilation for operational oceanography, circulation dynamics, biogeochemical studies, satellite observations, and air-sea interactions. The aim of this paper is to provide suggestions for KOGA planning and applications.
