Currently, the establishment and management of civil defense shelters are under the initiative of the government and local governments to protect the lives of citizens. In the future, there is a need for efficient civil defense shelters operation through the expansion of general shelters, including designated dedicated shelters. Therefore, it is more efficient to consider the distribution of residents and the location of access to shelters, not the quantitative operation considering only the number of residents. This study uses genetic algorithms and Huff gravity model based on census output data, building data, and road network information to understand the distribution of inhabitants more precisely than existing administrative district data. In addition, the spatial- database was used for efficient data management and fast processing, and if this study is improved, it can be used as a basis for the selection and improvement of general shelters positioning for a wider area.

In this paper, we described configuration and construction of infrastructure for the KASS Reference Station (KRS), subsystem of Korea Augmentation Satellite System (KASS). KASS system consists of three subsystems(KRS, Mission Control Center (MCC), KASS Uplink Station (KUS)). One of these subsystems, KRS receives GNSS data for generating range error and integrity verification and sends to MCC. It is needed to antenna facilities for mounting GNSS antenna and shelter for operating KRS and infra equipment(power and network system, lightning and grounding system, fire extinguish) for operating KRS. For this reason, we have established the requirements for KRS infrastructure and constructed infrastructure for KRS to meet the requirements of KRS infrastructure.

Various studies have been conducted to analyze the location appropriateness and capacity of shelters. However, research on how to select new shelters is relatively insufficient. Since the shelter is designated in case of emergency, it is also necessary to efficiently select the location of the shelter. Therefore, this study presented a method for selecting the location of the shelter using network analysis that has been used to analyze the location appropriateness of shelters and genetic algorithm which is a representative heuristic algorithm. First, the network analysis using the existing civil defense evacuation facility data was performed and the result showed that the vulnerability of evacuation has a high deviation by region in the study area. In order to minimize the evacuation vulnerable area, the genetic algorithm was designed then the location of new shelters was determined. The initial solution consisting of candidate locations of new shelters was randomly generated and the optimal solution was found through the process of selection, crossover, and mutation. As a result of the experiment, the area with a high percentage of the evacuation vulnerable areas was prioritized and the effectiveness of the proposed method could be confirmed. The results of this study is expected to contribute to the positioning of new shelters and the establishment of an efficient evacuation plan in the future.

우리나라는 지구온난화에 따른 기후변화에 의해 홍수피해가 점점 늘어나고 있는 실정이다. 이에 따라 홍수피해를 최소화 하는 주민대피체계를 제시하고 있지만 각각의 지자체의 특성을 반영하지 못하고 있다. 이재민 수용소의 인원이 부족하거나, 대피로 경로가 안전하지 못하여 2차 피해가 일어날 수 있는 가능성을 가지고 있는 곳들이 존재하고 있다. 이러한 상황에서 재해가 발생한다면 2차 피해가 발생할 가능성을 가지고 있기 때문에 이재민 수용소의 추가 지정과 대피로 경로를 새로 지정한다면, 재해 발생 시에 피해를 줄이고 보다 신속하고 안전한 대피가 이루어 질 것을 기대할 수 있다. 본 연구에서는 의령군이 현재 지정하고 있는 이재민 수용소 및 대피로를 평가하여 이재민 수용소를 재선정하였다. 의령군은 위험지역에 대해서 32개의 이재민 수용소를 지정하여 운영하고 있었으며, 그 규모는 7,165명을 수용할 수 있는 것으로 조사되었다. 하지만 이 중 봉수면과 의령읍은 이재민 수용시설의 규모가 대상지역의 대피 인원보다 작게 조사되어 이재민 수용소의 증원이 필요한 것으로 나타났으며, 가례천의 대피로는 하천을 wlsk가야 하는 경로로 지정되어 있어 2차 피해의 우려가 있는 것으로 나타났다. 이와 같이 수용인원이 부족한 이재민 수용소에 대해서는 증원을 통하여 문제를 해결하였고, 이재민 수용소의 위치는 피재자의 평균보행속도를 고려하여 15분 동안에 남녀가 이동할 수 있는 보행거리인 1,125m 이내에 위치하는 이재민 수용소를 채택하였다(유완, 도시의 재해대피소 적정 위치선정 2005). 이재민 수용소의 적절한 위치 선정을 통하여 지정한다면 재해발생시 피해를 최소화 할 수 있으며, 신속하고 안전한 대피를 할 수 있을 것으로 판단된다.
