우리 나라는 오래 전부터 민방위 차원에서 각 지역에 대피소를 선정해두고 정부 해당 부처의 게시판으로 알리고 있다. 그러나, 민방위 훈련이 거의 실시되지 않는 터라 대부분의 국민들은 어느지역에 어떤 대피소가 마련되어 있는지 알지 못한다. 최근에는 민방위 뿐만 아니라 바닷가 해일에 대비하기 위한 대피소도 늘어나고 있는데 이를 알고 있는 국민 또한 많지 않다. 따라서 이 연구에서는 현재 위치 주변에 어떤 대피소가 있는지와 가장 가까운 대피소까지의 길을 안내하는 긴급 대피소 안내 앱을 개발한다. 그 외에 이 앱은 지역별로 최근 발송된 재난 문자를 검색하는 기능도 제공한다.

In Korea 2016, the largest earthquake occurred in Gyeongju since the beginning of monitoring earthquakes. Consecutively the second-largest earthquake occurred in Pohang. At that time, immediately after the earthquake, citizens were not notified adequate information for evacuation. In consequence the response process was very confusing and citizens were not able to properly evacuate to shelter. For resolving these problems, it is needed of a service to inform quickly information which citizens want to know immediately after the earthquake. So, we have developed the customized information service model, the earthquake safety service which help citizens to escape safely using an earthquake shaking alert device. In this paper, we will introduce this model and present the future direction of R&D and strategic plans for technology dissemination and improvement of practicality through user demand survey.

This study aims to determine the factors affecting the level of satisfaction with the Cell Broadcast Service (CBS) among citizens in Incheon. Partial least squares (PLS) regression, instead of multiple regression, was used for the analysis because it can solve multicollinearity and sample size issues. The analysis results are as follows: The factor with the greatest effect on satisfaction with CBS among Incheon citizens, was the elimination of redundancies (VIP=1.185). Therefore, local governments, government agencies, and public organizations must coordinate their ideas and collectively create guidelines to eliminate redundancies. The second most influential factor was the expansion in the broadcast medium from legal, institutional, and policy aspects (VIP=1.087). This is because differences in generation, age, gender, and personal characteristics were not considered. Therefore, it is necessary to devise a customized messaging tool through the expansion of broadcast media. The broadcast criteria of the legal, institutional, and policy perspectives comprised the third most influential factor, with a high VIP value of 1.053. Consequently, it is essential to devise a plan to avoid distributing unnecessary cell broadcast services, by establishing criteria for areas and sections, time, and the direct and indirect impact zones of a disaster. In the future, this study could be used as base data to develop policies, guidelines, and response measures for Incheon CBS. Given the lack of research on the diverse characteristics of each social class and the city traits of each region, and a lack of concrete empirical research on each factor, continuous and in-depth studies are required in the future.

In this study, a formula was derived to calculate the damage impact distance using the Chemical Accident Response Information System (CARIS) so that local governments can decide on the evacuation and notification of 13 types of substances. The National Institute of Chemical Safety selected 16 out of 97 types of accident preparedness substances in 2018 and called them residents' evacuation preparedness substances. In a chemical accident, local governments should prepare for resident notification, such as emergency disaster texts. Using the CARIS in Chungju, this study modeled the damage-affected distances of 13 types of substances for the evacuation of residents. Under all conditions, the coefficient of determination R2 was 0.99 or higher, representing a range of at least 0.9921 to a maximum 0.9999. The relative standard deviation between the damage impact distance obtained using the calculation formula, and the CARIS result was compared. The minimum separation distance was corrected considering the actual chemical accident response situation, and the range was found to be between 0.58 and 5.97%. The damage impact distance can be calculated at the site using the calculation formula derived from the research, and local governments can determine whether to evacuate or notify residents.
