공익을 목적으로 제공되는 재난경보 서비스에서 누군가의 해킹으로 잘못된 재난경보 메시지가 전달되면 사회적으로 큰 혼란이 발생할 수 있다. 본 논문에서는 지상파 UHD 방송을 통한 재난경보 메시지가 해킹으로부터 안전하게 보호될 수 있도록 ATSC 3.0 표준에 정의된 서명 방식을 기반으로 하여 보안 기능을 구현하는 방안을 제안한다.

기상이변에 의한 자연재해나 방사능 유출, 가스폭발 등에 의한 인재는 예보방송도 중요하지만 사고 현장에 있는 사람들에게 현재의 상황 정보를 전달하고 행동지침 요령을 전달하여 2차 피해를 예방하고 재난 지역 및 재산상의 손실을 최소화 시킬 수 있기 때문에 긴급 재난 방송 또한 매우 중요하다. 지상파 DMB는 휴대폰, PMP(Portable Multimedia Player), 내비게이션 등과 같이 개인 휴대 단말기와 결합된 형태로 보급되어 보급률 및 사용률이 매우 높으며 이동 중에도 별도의 비용 없이 양질의 데이터 수신이 가능하기 때문에 긴급 재난 방송 서비스를 시행하는데 있어 가장 최적화 된 모델로 평가된다. 이에 본고에서는 국내 재난방송의 특성을 살펴보고 지상파 DMB를 이용하여 어떻게 긴급 재난 방송 서비스를 할 수 있는지 서비스의 구조와 특성에 대해 알아본다. 또, 향후 긴급 재난 방송이 우리 생활에 끼치는 영향과 앞으로의 해결되어야 할 문제점에 대해 고찰한다.

국가기반시설의 기능 상실은 신속한 재난 대응 및 복구를 불가능하게 할 뿐만 아니라 국가안보의 심각한 위협요인으로 작용한다. 본고에서는 국가주요시설의 체계적 위험도 관리를 위한 DB 현황 조사 및 분석을 수행하였으며 국내외 국가기반시설의 취약성 평가 절차를 조사 분석하였다. 조사에 따르면 선진국의 경우 다양한 기반시설 분야에 적합한 재난관리 방법론을 연구하고 그에 적용할 수 있는 시스템을 구축하여 재난 예방, 관리, 분석 등의 서비스를 제공하고 있다. 우리나라의 경우 국가에서 관리되는 시스템의 활용범위와 같이 시스템의 대부분이 상황전파 및 재난신고접수와 사후 피해 상황 보고 등의 복구진도관리 위주로 운용되고 있으며 취약성 분석 및 시설체계관리의 효율성을 증대하는 기능은 미비하여 복합적인 재난 유형에 적합한 관리체계가 마련되어 있지 못하고 있다. 이에 본고에서는 다양한 국내외 체계 및 사례를 조사하여 국가기반시설 간 상호의존성을 고려한 복합재난 관리 체계를 소개하였다.

Governments intend to use the public warning system to deliver timely and accurate information using accessible communication technologies for protecting the population and reducing damage to life and property. In particular, many countries implement system interworking with smartphones to notify of disasters or emergencies. In Korea, since 2020, due to the influence of the coronavirus disease, frequent emergency text messages led people to turn off related notifications, and complaints for receiving irrelevant messages from nearby warning areas have increased. Therefore, technical improvements for issuing more accurate disaster information to a specific region should be devised through a geography-based emergency disaster message transmission service. We analyze development trends of public warning systems and service cases of geography-based emergency text transmission services in various countries.

This study was attempted to understand the relationship between disaster awareness, disaster attitude, and disaster response ability of the general public, and to be used as basic data to raise awareness of disasters and prepare countermeasures. This study was conducted from July 16 to July 31, 2021 for a total of 250 ordinary people living in K-do and D metropolitan cities. As a result of this study, it was found that it had an effect between disaster awareness, disaster attitude, and disaster response ability. Specifically, it was found that the general public's awareness of disaster had a significant effect on disaster attitude (necessity for disaster preparation, disaster management) (p<.001). In addition, among the sub-factors of disaster attitude, disaster management was found to have a significant effect on disaster response ability (p< .01). Therefore, specific and periodic education should be prepared to increase the ability to cope with disasters by increasing the general public's awareness of disasters.

Marine disaster, such as 'Dolphin Lake ship', "the Sewol ferry', on the ocean needs emergency communication with land post and Rescue services. It needs of emergency communication system has increased in Republic of Korea peninsula with the sea on three side. The system will be more fully equipped to deal with disasters linked to communication so alone sailing ship is at sea. Research is needed on communication links to submarines operated by submarine to sink a ship, as well as immersion in the sea with. And it is necessary in the study of the land in preparation for the emergency disaster ship and submarine communication links for offshore and subsea oil and associated communication systems. Will be studied in preparation for the communication protocols and emergency and disaster location and land the plane or for a career in the satellite systems are linked through this.

In Korea, various information related to COVID-19 has been provided to the public through an EAM (Emergency Alert Message) service using CBS (Cell Broadcast Service) technology to respond to COVID-19. In particular, local governments have been actively using the EAM service as a major means of responding to COVID-19. However, since excessive use of EAM service has caused the inconvenience of the people rather than the positive effects, the authority to be able to send EAMs has be limited. In this paper, with the purpose of providing primary data for establishing a plan to properly operate EAMs, we compare and analyze the number of EAMs issued and the incidence rate of COVID-19 cases during the period from 2020 to the present. In addition, the monthly EAM usage and incidence rate of COVID-19 cases are compared in detail and correlation analysis is performed for local governments that have issued many EAMs. We expect that the analysis results of this paper will be used as primary data in establishing strategies for EAM service to counteract the prolonged COVID-19.
