많은 인구가 몰리면 군중 추돌 현상과 도미노 현상이 발생하여 압사 사고가 일어나 이에 대한 해결책이 요구된다. 본 논문에서는 위 문제를 개선하고자 보행자 상황 인식을 이용한 재난 경고 시스템을 구현하였다. 이 시스템은 재난관리기관에서 기존에 운영하고 있는 것과 같은 CCTV영상을 이용하여 딥러닝 영상인식 기술을 사용하여 보행자 안전 규정에 따른 보행자 상황을 인식해 재난 상황을 표시해주고, 경고를 한다. 보행자 상황 인식하기 위해 엣지컴퓨터에서 연결된 카메라 영상을 받아 상황인식을 하고, 인식된 상황과 영상을 서버로 전송하여 정보를 저장하고, 상황을 경고 한다. 상황인식을 위해 보행자 데이터는 직접 수집하여 학습시킨 weights 파일을 사용하였다. 보행자 인식은 YOLOv4-tiny를 사용하였고, 위험 단계는 총 4단계로 설정하였다. 이를 활용하여 기존의 CCTV영상을 활용하여 관리자를 보조하여 보행자 재난 상황시에 신속하게 재난을 인식하여 구호 조치를 할 수 있다.

The purposes of this study were to examine the coping behavior of the elderly in the warning phase of disaster and to explore factors influencing the coping behavior of the elderly. Data were collected from 130 senior citizens aged over 60 who are residing in Pyungchang and Injae of Kangwon province which had damaged by flood disaster in 2006. Perry & Lindell (1997)'s index, a series of six categories that represent coping behaviors which progressively approximate the action of evacuating in the warning phase of disasters was used. Results showed that respondents have high coping skills. Although Activities of Daily Living (ADL) has positive influence on the coping behavior, length of residence has negative effect on the coping behavior of the elderly. This finding proves the elderly are not uncompliant or uncooperative population in the warning phase of disaster. This result also emphasizes the importance of rapid and accurate giving of public warning system of disaster and necessity of prior notification of useful information about natural disaster and effective evacuation plan for the elderly.

In the event of a disaster (or accident), first of all, the ability to respond to an immediate disaster is important. This study investigated the disaster response capacity and the effects of disaster response exercise personnel. A questionnaire consisting of 28 items was used to assess disaster response capabilities. The questionnaire consists of contrast, preparedness initial response, warning, and response steps. Survey participants are self-service fire-fighters of small and medium-sized manufacturing companies participating in exercise. The effectiveness of the exercise. was measured by dividing the subjects before and after the exercise. Analyzing the difference between before and after exercise, it was confirmed that disaster response exercise. had significant effects on improving disaster response capacity. This study suggests that the disaster response exercise. has the effect on the disaster response capacity of the members and the necessity of disaster response exercise. As in the case study, if a company or organization regularly conducts disaster response exercise., its disaster response capabilities will improve. In addition, it is anticipated that in the event of a disaster (or accident), it will be possible to prevent or reduce property damage as well as property damage.
