Since marine accidents cause large-scale damage to human lives and the marine environment, prompt response measures are crucial including salvage operations for ships and cargoes along with lifesaving operations. In Korea, marine salvage operations are mainly dependent on global salvage companies in case of large-scale marine accidents due to lack of national capacity for marine salvage. The purpose of this study was to suggest public measures for the promotion of the private salvage industry by identifying the current situation and problems in the domestic marine salvage industry. As a result of the study, the measures of setting up a dedicated agency to support the domestic salvage industry and the function of the dedicated agency were identified and presented. In addition, the main points of the bill of "Law on the Promotion of the Domestic Salvage Industry" were presented to support and promote the salvage industry. To prepare the draft bill of law, relevant domestic laws and international conventions were examined to define the terms and regulations. Based on the legislation enacted as a result of this study, relevant ministries should focus on the legislative process. Legislation can be pursued by competent ministries in cooperation with the private sector and academia. It is expected that this study will help in the development of the domestic marine salvage industry and enhance the national response capacity for marine accidents in Korea.

Recently, novel viral infections such as COVID-19 have spread and pose a serious public health problem. In particular, these diseases have a fatal effect on the elderly, threatening life and causing serious social and economic losses. Accordingly, applications such as telemedicine, healthcare, and disease prevention using the Internet of Things (IoT) and artificial intelligence (AI) have been introduced in many industries to improve disease detection, monitoring, and quarantine performance. However, since existing technologies are not applied quickly and comprehensively to the sudden emergence of infectious diseases, they have not been able to prevent large-scale infection and the nationwide spread of infectious diseases in society. Therefore, in this paper, we try to predict the spread of infection by collecting various infection information with regional limitations through a virus disease information collector and performing AI analysis and severity matching through an AI broker. Finally, through the Korea Centers for Disease Control and Prevention, danger alerts are issued to the elderly, messages are sent to block the spread, and information on evacuation from infected areas is quickly provided. A realistic elderly support system compares the location information of the elderly with the information of the infected area and provides an intuitive danger area (infected area) avoidance function with an augmented reality-based smartphone application. When the elderly visit an infected area is confirmed, quarantine management services are provided automatically. In the future, the proposed system can be used as a method of preventing a crushing accident due to sudden crowd concentration in advance by identifying the location-based user density.

Most of marine casualties occur at the coastal sea areas where maritime traffics are heavy and on the coastal regions such as the beaches and breakwaters, etc. where a lot of people visit. Recently, tile risk of casualties along the coasts has been on the increase due to the revitalization of marine leisure activities in Korea. However, the measures to prevent accidents along the coasts have not kept step with increasing rate of the accidents and the safety management system has not been organized. Recent marine casualties were analyzed to propose alternative measures for safety management to minimize marine casualties along the coasts. Comprehensive safety system and networks are necessary to be established and the integration and unification of the relevant authorities in charge should be accomplished in Korea. In rapid response to marine casualties, the search and rescue system should be established for the systematic and effective life-saving operations in Korean coastal areas.

Traffic accidents are caused by a variety of factors. Among the factors that cause traffic accidents are weather conditions at the time. There is a difference in the percentage of deaths according to traffic accidents, due to the weather conditions. In order to reduce the number of deaths due to traffic accidents, to predict the incidence of traffic accidents that occur in response to weather conditions is required. In this paper, it propose a model to predict the incidence of traffic accidents caused by weather conditions. Predictive modeling was applied to the theory of Markov processes. By applying the actual data for the proposed model, to predict the incidence of traffic accidents, it was compared with the number of occurrences in practice. In this paper, it is to support the development of traffic accident policy with the change of weather.

As the era of the 4th Industrial Revolution has progressed and the information and communication technologies have developed dramatically, the cyber threats will gradually become more intelligent and sophisticated. Therefore, in order to take systematic and prompt action in case of an accident while preparing measures against the threat, the role of intelligence agency is important. However, Korea is having difficulty in responding to the threats due to the lack of support for the national cybersecurity bill or the amendment bill of the National Intelligence Service. In this paper, I examine the cybersecurity function of the intelligence agency, the recent debate trends, and implications for the role of intelligence agency in our current situation. And then I intend to suggest some measures such as concentration on information gathering and analysis, enhancement of cyber threat prediction and response capacity, and strengthening of legal basis as a way to establish the role of intelligence agency for reinforcement of cybersecurity performance system.

High cognitive workload decreases a driver's ability of judgement and response in traffic situation and could result in a traffic accident. Electrocardiography (ECG) has been used for evaluation of drivers' cognitive workload; however, individual differences in ECG response corresponding to cognitive workload have not been fully considered. The present study developed an evaluation method of individual driver's cognitive workload based on ECG data, and evaluated its usefulness through an experiment in a driving simulator. The evaluation method developed by the present study determined the optimal ECG evaluation condition for individual participant by analysis of area under the receiver operating characteristic curve (AUC) for various conditions (total number of conditions = 144) in terms of four aspects (ECG measure, window span, update rate, and workload level). AUC analysis on the various conditions showed that the optimal ECG evaluation condition for each participant was significantly different. In addition, the optimal ECG evaluation condition could accurately detect changes in cognitive workload for 47% of the total participants (n = 15). The evaluation method proposed in the present study can be utilized in the evaluation of individual driver's cognitive workload for an intelligent vehicle.
