Abstract
Purpose: This study aims to empirically analyze the utilization and limitations of the PS-LTE-based communication network in wildfire disaster response and to identify the demand and concerns regarding next-generation integrated networks, including low Earth orbit(LEO) satellite communication, in order to propose practical measures for enhancing disaster communication systems. Method: An online survey was conducted with 127 employees of the Korea Forest Service and its affiliated agencies, and the collected data were analyzed using frequency analysis and the Analytic Hierarchy Process(AHP). Result: The findings revealed low utilization of PS-LTE, frequent communication failures particularly in coverage shadow areas and high demand for satellite communication integration, along with practical concerns such as device portability and compatibility. Conclusion: Upgrading communication infrastructure, strengthening inter-agency interoperability, and expanding field-oriented training were identified as key priorities, underscoring the need to establish both policy and technical foundations for building an integrated disaster communication network.

연구목적: 전기자동차와 ESS 증가로 폐배터리 재사용을 위한 과정에서 발생할 수 있는 리튬이온배터리 화재 위험에 대응하기 위해 비전도성 수계형 소화약제와 전용 소화기 시스템을 개발하고 그 성능을 검증하는 것을 목적으로 하였다. 연구방법: 파우치형 폐배터리를 충전한 후 히팅패드로 열폭주와 화재를 발생시켜 개발된 수계형 소화약제와 미세분무 노즐 소화기를 사용하여 A급(일반화재) 및 C급(전기화재) 소화성능을 평가하였다. 전도도시험, A급 목재더미 화재시험 및 파우치형 리튬이온배터리 화재 시험을 통하여 소화 성능, 냉각 효과 및 재발화 억제 능력을 시험하였다. 연구결과: 개발된 수계 소화약제는 전기 전도도 100μS/m로 C급 전기화재 기준을 충족하였으며, A급 목재더미 화재 시험에서는 60초 이내 진압과 재발화 방지 성능을 확인하였다. 또한 폐배터리 화재 시험에서 열폭주 확산 억제, 신속한 냉각 및 인접 셀 보호 효과를 확인하였다. 결론: 본 연구의 소화약제와 소화 시스템은 폐배터리 재사용 및 보관 시 발생 가능한 화재 위험에 대응할 수 있는 효과적인 안전대책임을 입증하였으며, 향후 다양한 배터리 형식과 대규모 ESS 및 전기차 배터리 팩에 대한 적응성 검증을 통하여 실용화를 확대할 예정이다.
