  • As the modern maritime industry rapidly progresses through technological advancements, data processing technology is emphasized as a key driver of this development. Natural language processing is a technology that enables machines to understand and process human language. Through this methodology, we aim to develop a model that predicts the proportions of outcomes when entering new written judgments by analyzing the rulings of the Marine Safety Tribunal and learning the cause-providing ratios of previously adjudicated ship collisions. The model calculated the cause-providing ratios of the accident using the navigation applied at the time of the accident and the weight of key keywords that affect the cause-providing ratios. Through this, the accuracy of the developed model could be analyzed, the practical applicability of the model could be reviewed, and it could be used to prevent the recurrence of collisions and resolve disputes between parties involved in marine accidents.

  • Purpose - This study aimed to analyze the dynamic effects of progress in globalization on firm performance by employing individual companies' financial statement datasets. Design/methodology - The analysis leveraged the variables of operating revenue (OPRE) and pre-tax profit and loss (PLBT) as measurement variables for firm performance over 2011-2019. As a proxy variable for globalization, the trade index, a subordinate indicator of the KOF Globalization Index, was used. Through panel regression analysis, the relationship among those variables was ascertained, and the local projection (LP) method was subsequently utilized to identify dynamic effects. A subsample analysis was further performed by classifying companies based on their sizes and industries to determine the differential effects of globalization on each group. Findings - The panel regression analysis derived positive effects of an increasing degree of globalization on OPRE of Korea maritime and fishery firms. However, the impulse response functions, obtained from the LP, showed that in the short run, globalization affects PLBT negatively but in the long run, it gradually converted into a positive effect. In addition, according to the subsample analysis based on company size, the effects of globalization on OPRE became greater as each company became larger. Moreover, the industry-based analysis showed heterogeneous effects, depending on the industries in which the maritime and fishery companies operated. Originality/value - The analysis of the dynamic effects of globalization on firm performance, which revealed that the effects vary depending on the time points, is the important contribution of this study. The results also suggest that the effects of globalization vary depending on the company size and industry.

  • Korea's shipbuilding industry has led the world in the technical area over the last century. Despite this commendable performance, around 2,000 workers experience accidents almost every year with 40 being killed. This raises a question of whether the safety level of our shipbuilding industry, in particular the safety of workers, is actually at the world-class level. Accordingly, this research has analyzed several types of safety training currently provided in the field through investigating statistical data of serious accidents occurring from 2006 to 2015 in the domestic shipbuilding industry, analyzing its occurrence and causes, and conducting a survey targeting employees in the shipbuilding industry. Based on this, it has investigated problems of safety training in the shipbuilding industry and suggested improvements. First, it is essential to create a standard system for safety training in the shipbuilding industry to address problems of different kinds and levels of safety training provided by each shipyard and low quality of training, and operate more organized and systemized training. Second, safety training curriculum specializing in the shipbuilding industry should continue to be developed and standardized based on a standard system for safe training to prevent serious accidents and improve safety awareness of workers. Lastly, both employers and employees should actively provide and participate in safety training to secure safety of workers through preventing serious accidents and ultimately create safety-first culture in workplace.

  • The International Maritime Organization(IMO) which is responsible for measures to improve the safety and security of international shipping and to prevent marine pollution from ships is a specialized agency of the United Nations. It is involved in legal matters, including liability and compensation issues and the facilitation of international maritime traffic as well. But the ROK has not been actively coping with the environment of the shipping industry because of the absence of the organization or researching bodies that specialized in the field related to IMO. Therefore this paper investigates the maritime administration system of the major countries such as the USA, japan and the UK. And particularly by conducting IMO research and responding system, this study gathers relevant materials from those countries for the comparison and analysis with the purpose of providing the ROK with the assistance in forming the responding measures in the shipping and shipbuilding industries.

  • Korea has established the MOMAF (Ministry of Maritime Affairs and Fisheries) in 1996 while only a few countries have adopted the unified management system for the area of maritime, oceans and fisheries affairs. The Ministry has been broken up to three parts of maritime affairs, oceans and fisheries and allocated to each related ministries in 2008, and reorganized as the Ministry of Oceans and Fisheries including maritime affairs in 2013. However, the newly established MOF (Ministry of Oceans and Fisheries) has been evaluated as simply duplicated the former organization so as not to meet the oceanic environmental changes. This paper aims to suggest the appropriated organizational reinforcements measures on the basis of analysis of questionnaire survey which has been conducted targeting experts such as academic researchers and industry field players in the area of oceans, maritime and fisheries. The survey pointed out mainly five scopes such as (1) transferring the administrative task of shipbuilding and plant industries from the existing Ministry to the MOF, (2) reinforcing the structural functions of maritime, port construction and logistics affairs, (3) collaboration system with related Ministries for the ocean sovereignty, (4) securing the financial support system for the maritime industries, (5) transferring the management authority of maritime and ocean universities from the existing Ministry to the MOF. Looking back on the interministerial interest conflicts, it is very difficult to agree on the transfer of the existing task of above first and fifth suggestions. But the remain three suggestions could be done with interior abilities of the MOF by means of structural changes and professional manpower supplement.

  • Carbon fiber is an excellent structural material, which has been proven in many industries, and the shipbuilding industry is no exception. In particular, in advanced maritime countries, special ships of the Navy and Coast Guard with carbon fiber composite hulls have already been deployed. In Korea, carbon fiber composite materials have been applied to a 10-ton class leisure craft or a 30-ton class patrol, but no research has been done on a hundred of tons or more vessels. In this study, the feasibility study of a 500-ton patrol vessel with a carbon fiber composite hull was conducted through an analysis of similar cases abroad. As a result, it was recognized that the developed hull can be reduced in weight by about 21% to 25% compared to the existing aluminum or FRP hull. It was also confirmed that this light-weight effect can induce the improvement of the maximum speed and the improvement of the operating range via simulations.
