  • In this study, around Jeju area where climatic change is most considerably appearing in Han Peninsula, we prepared sea level rise height caused by sea level rise (Seogwipo 5.6 mm/yr, Jeju 5.3 mm/yr) and a sea level rise scenario for the case when an enlarged typhoon attacks during high water ordinary spring tide, and evaluated flooding area and effect on road and facility using Digital Elevation Model(DEM) and GIS Spatial Analysis Technique. As a result, the flooding areas were shown to be 2.9 $km^2$ in 2040, 5.4 $km^2$ in 2070, and maximum 5.4 $km^2$ in 2100. Analyzing the effect of flooding on each type of road, the local roads(Gun-do) were shown to be mostly affected. The most flood effected facilities were individual houses. Especially, as there is a possibility for casualties to occur due to disaster in Hwabuk-dong because the effect of flooding on individual houses in this area was shown to be high. In addition, flood on port facilities will considerably affect logistic and marine activities. This study is thought to be a basic data which can be utilized for establishment of strategic coping measures and policies of government affiliated organizations through analysis of effect of sea level rise on construction field.

  • In the era of the fourth industrial revolution, Maritime Autonomous Surface Ship(MASS) are expected to emerge in the shipping industry. There has been much active research on collision avoidance systems regarding MASSs, but most of it has focused on merchant ships. A study of collision avoidance systems in fishing vessels is also essential, because Maritime Autonomous Surface Ships will encounter all type of vessels. In this study, the minimum passage distance between small-medium-sized fishing vessels and other vessels was investigated for the Ship's domain analysis. Based on the AIS data of Busan port and the adjacent area, the separation distances of fishing vessels were analyzed. The results indicated that as the speed of fishing vessels increased, the distance increased from 4L to 8L, and as length of the fishing vessels increased, the distance decreased from 10L to 6L. It is believed that the results of this study can be applied in the future to collision avoidance models for MASSs that reflect the domain of fishing vessels.

  • Safety and security measures in the shipping industry play a pivotal role in ensuring efficient and reliable cargo and passengers operations at each stage of the supply chain. The ISPS Code was adopted into SOLAS convention to protect seafarers and vessels from security threats. Furthermore, according to the Manila amendments to STCW Convention in 2010, personnel employed on board are required to participate in security training. Effective seafarers' education and training programs are of major importance to guarantee satisfactory performance levels onboard to minimize security-related risks. The study's contribution focuses on empirically evaluating the relationship between personal level of awareness and security performance when seafarers undertake security training courses. Findings of this study suggest that (1) seafarers who undertake maritime security training have a higher awareness of ship security, (2) security training and security awareness have a positive influence on security performance, and (3) security awareness mediates the impact of security training and security performance. In conclusion, education and training programs are key tools in enhancing seafarers' security awareness and security performance which, from an industry viewpoint, can translate into major economic, operational and reputational benefits.

  • Recently, international convention competition has greatly expanded with the globalization and expand of world economy. As the conventions market has grown, so have the number of places and facilities of convention competing for business, and numerous trade show and the related meetings held the several cities toward world city such as the United States, Europeans Countries, Japan, and Singapore. Convention, in general, are defined as an assembly, often periodical, of members or delegates, as a political, social, professional or religious group. Convention center means the place that hold several social, political, economic conferences and meetings, trade show, exhibitions, and events. Convention center are consisted the several facilities such as meeting room, exhibition hall, event hall. Historically, meetings, conventions, and trade show have been serviced primarily by hotel and convention centers. With the expand of world trade and flow in recent, the conventions, expositions, and meetings industry (CEMI), however, is one of the most rapidly growing industries in hospitality and tourism, and CEMI provides import effect on regional economy and regional development including regional tourism industry. This study focuses on the establishment strategies and location analysis of convention center as a agent for regional development in a case of Yosu Peninsular Area (YPA). YPA is one of the major industrial area of our country, and displays the rapid regional urbanization and social change with the construction such as Kwangyang container port facilities, Yulchon industrial complex, and the extension planning of industrial estate related to Kwangyang Iron and Steel Company, and population size of this area will be reached about two million peoples in 2011. This area, particularly, will be functioned as a major container & export port of our country after the completion of Kwangyang container port facilities in 1988. If the planned industrial estate is constructed, the convention center for conference exhibition, information exchange, and resort facilities for exhibition, international communication will be needed. In addition, resort and leisure facilities for conventions' participants need. This area, therefore, has to make the establishment of convention center for regional development in future. Thus, the major strategies and idea for establishment of convention center as follows: first, this area has requirements for resort convention center, because this area will be functioned as a major export port and industrial district in 21 century; second, in the location analysis of convention center site, Sinwol & Woongchon district, Soho district, and Yongju & Hodu district are selected as developing possible sites; third, the convention center of this area has to consist of two functions such as convention facilities and marine resort facilities; fourth, in order to establish convention center, the selection of main group, financial raising strategies, and the organization of propulsion committee for establishment of convention center are required.

  • Since 2008, China's shipping industry has been in a slump, with shipbuilding orders falling sharply, and high-growth excess capacity has become increasingly apparent, leaving many firms with sharply reduced orders at risk of bankruptcy and shutdown. To ensure the development of the shipbuilding industry and enhance the international competitiveness of the shipbuilding industry, it is necessary to analyze the present situation of the shipbuilding industry and the financial situation of the shipbuilding enterprises. And analyzing the problems faced by enterprises from the perspective of capital structure is very meaningful to the shipbuilders with high capital operation. We are trying to analyze the determinants of capital structure of China's shipbuilding listed companies. 30 listed Chinese shipbuilding and listed companies have been designated as sample companies that can obtain financial statements for 13 consecutive years. They also divided 30 sample companies into shipbuilding, shipbuilding-related manufacturing, and shipbuilding-related transportation. Dependent variable is the debt level of the year, independent variable includes the debt level of the previous year, fixed asset ratio, profitability ratio, depreciation cost ratio and asset size. The regression model of the panel used to analyze determinants is capital structure. The results of the empirical analysis are as follows. First, a fixed-effect model for the entire entity showed that the debt-to-equity ratio and the size of the asset in the previous period had a positive effect on the debt-to-equity ratio in the current period. Second, the impact of the profitability ratio on the debt level in the prior term also supports the capital procurement ranking theory rather than the static counter-conflict theory. Third, it was shown that the ratio of the depreciation of the prior term, which replaces the non-liability tax effect, affects the debt-to-equity ratio in the current period.
