Demands to Develop Marine Science Technology to Reduce Damage of Disasters Caused by Marine Accidents

The purpose of this study is to ascertain the demands for developing marine science technology to reduce fatalities caused by marine accidents. For this purpose, we analyzed the contents of about 77,000 news articles posted for a month after the tragedy of the Sewol (April 16~May 15) to identify keywords and then we used the Social Network Analysis (SNA) for each keyword. The findings of the analysis show that there are five networks and that each one reveals different aspects about technology development to prepare for marine accidents. Based on these findings, we categorized three kinds of demands for technology development from the perspective of marine science technology: provision of the information about the marine environment, development of equipment and technology to overcome extreme environments, and the establishment of a field support system.
