  • The importance of the air and vessel traffic control center is increasing rapidly after the recent accident of 'Sewol ferry'. Aviation, marine, and the logistics sectors are already using monitoring and control technology widely. However, the monitoring and control system for complex and dangerous construction sites operation has yet to be employed. A monitoring/control system is required for effective communication between the control center and the construction equipment fleet at a construction site, and also the exact role that notifies accurate process and identification of hazards on construction sites as needed. Therefore, this paper presents the study about communication between the construction equipment fleet and the control center through the comparison of air traffic, marine, and logistics control systems for the development of construction equipment fleet management system.

  • People generally believe that disaster forecast and warning systems and response systems are well established in the age of cutting edge technology. As a matter of fact, reliable systems to respond to disasters are not properly equipped, as we witnessed the Sewol ferry disaster in 2014. The existing forecast and warning systems are based on sensor information with low efficiency, and image information is only operated by monitoring staff manually. In addition, the interconnection between a warning system and a response system in order to decide how to cope with the recognized disaster is very insufficient. This paper introduces the CCTV based disaster recognition and real time crisis response system composed of the CCTV image recognition engine and the crisis response technique. This system has brought the possibility to overcome the limitations of existing sensor based forecast and warning systems, and to resolve the problems in the absence of monitoring staff when responding to crisis.

  • Our society is endemic in safety insensitivity, yet we have been concerned for safety education and disaster drill since the Sewol Ferry accident. However, the practical training costs very high, and it has its limit to increase reality. Recently, industry fields put emphasis on virtual reality (VR) as alternatives, so various contents are invented by using advantages of VR. The paper explores crucial application in 3-dimensional simulation for fire drill, suggests novel design, and contemplates about educative result through designing process. In order to construct and materialize the suggested system, practical 3D spatial information model and various disaster-drill scenarios are necessary. Also, to apply game elements for augmentation in users' utility, educations based on computer science and visual art are inevitable, which requires skills in programing and modeling respectively. Thus, this study investigates educational effect of convergence field through the suggested system designing process.

  • In hosting outdoor activities and school trips, safety issues are gaining serious attention lately. In addition to Sewol ferry tragedy and an incident at Kyungjoo Mauna Resort, there have been grown problems related to this crucial factor. This research analyzes negligent accidents occurred from domestic and foreign schools and aims to provide effective safety education and policy through comparative analysis between domestic and foreign cases. We mainly relied on documents such as newspapers, internet articles and legal papers to investigate cases and cooperated with relevant government departments for collecting references and setting agenda for safety supervision. The analysis on both domestic and foreign cases revealed that students abroad receive opportunities for first-hand experience regarding safety and systematic education, as safety maintenance is prioritized. Based on this culture, safety education should be habituated domestically, while participatory safety programs that students can actively involve must also be devised. Moreover, through preparation of entertaining contents such as SNS game programs, skits and activities employing multiple facilities and vehicles at school safety education, we must induce students to actively participate in the program with interests.

  • The Ministry of Public Safety and Security was established in order to handle all sorts of disasters because of Sewol ferry tragedy and the fundamental reform on the emergency management system will be performed. The establishment of the Ministry of Public Safety and Security is considered as the landmark for the emergency management when it is compared to those in the United States and Japan in terms of the size and the authority. However, there are many tasks to be done for the settlement of the Ministry of Public Safety and Security. More specifically, a real and substantial plan should be prepared because the organization was established without blueprints or detailed implementation plan. This study suggests that all-hazard approach which is the one of the disaster management principles should be applied when the substantial plan is prepared. All possible hazard should be analyzed, assessed, and prioritized. In addition, Based on the results, the effective policies should be established with the consideration of Korean context.

  • After the Ferry Sewol accident, public interest in marine safety has increased. However, as the marine leisure tourism population increases, the number of casualties caused by marine accidents is increasing, so marine safety education is urgently needed. Since facilities related to marine safety education in Korea are geographically biased to the west, regional imbalances in education are significant. Therefore, this study suggested solutions to the problems of developing educational contents and securing budgets and professionals by using idle facilities of the Korea Institute of Maritime and Fisheries Technology(KIMFT) located in Busan as a maritime safety education center. In addition, as a result of estimating demand using the gravity model, it was estimated that the demand would range from 150,000 to 130,000 per year. This study sufficiently proved social policy validity for policy suggestions using existing idle sites as maritime safety education centers based on objective verification methods and is expected to contribute substantially to policy promotion in the future.
