최근 국가적 차원에서 자연재해대책법에 근거한 여러 방재심의제도를 운영하고 있다. 그 중 최상위 계획인 풍수해저감종합계획을 통하여 저감대책을 마련하고, 위험지구에 대한 대책과 사업을 시행중에 있다. 그러나 방재업무를 진행하는 중앙부처와 지자체, 방재대행업체자 등에서는 심의보고서간의 자료공유와 접근성이 미약하고 잦은 담당자 변경으로 인한 심의보고서 보관과 관리가 힘든 실정이다. 또한 제도간의 연계와 환류기능이 미흡하여 제도별로 산재되어 있는 부분이 많으므로 통합적으로 관리할 수 있는 운영체계가 필요하다. 따라서 본 연구에서는 풍수해 방재심의제도를 통합적으로 운영하고 관리하기 위한 시스템을 구축하는 것이 최종 목표이며, 이를 위해 우선적으로 풍수해저감종합계획 수립제도를 시범적으로 적용하여 운영 관리할 수 있는 시스템 기반을 마련하였다. 또한, 향후에 있을 방재심의제도별 통합적인 운영을 위해 선제적으로 재해위험지구 정비사업과 구성항목의 데이터 연계성을 분석하였으며, 이를 바탕으로 제도별 연계 시스템을 설계하여 제시하였다.

홍수기 하천에서 유량측정은 예산, 인력, 안전 및 측정 시 편의성 등의 이유로 측정에 제한이 많다. 특히, 태풍 등으로 인한 호우사상 발생 시 위와 같은 문제로 홍수량 측정에 어려움이 따른다. 이러한 문제점을 개선하기 위해 Lee et al.(2021)은 드론과 전자파표면유속계의 기능을 융합한 DSVM(Dron and Surface Veloctity Meter using doppler radar) 측정방법을 개발하였다. 전자파표면유속계 측정의 제한 요소인 진동을 감소시키기 위해 댐퍼플레이트를 개발하였고 금강의 지류인 봉황천에 현장 적용을 통해 DSVM 측정방법의 실용성을 확인하였다. 기존 연구에서 DSVM 방법은 드론의 각 측선 이동을 위한 조종과 전자파표면유속계 측정의 제어를 측정자가 수행하였는데 본 연구에서는 통합 드론측정시스템(IDMS, Integrated Drone Measurement System) 개발을 통해 측정자의 조종 의존도를 줄임과 동시에 안전하고 정확한 유량측정을 위해 노력하였다. 기존 댐퍼플레이트의 상하 진동 흡수 기능뿐만 아니라 전자파표면유속계의 흔들림 현상 등 자세 제어 기능을 보완하기 3축 모터를 적용한 방수짐벌을 개발하여 측정 정확도를 향상시켰다. 미션컴퓨터 개발로 측정지점의 측정 임무정보를 DB화하여 각 측선별 헤딩, 고도, 이동 등 자동항법 기능과 기체의 안정화 이후 전자파표면유속계를 자동으로 제어하여 측정을 실시하는 기능을 구현하였다. 또한 통합 GCS(Ground Control System)를 통해 비행 및 측정에 대한 모든 정보를 확인하고 컨트롤 할 수 있게 하였다. 2022년 금산군(제원대교), 무주군(취수장), 경주시(서천교) 지점에서 홍수기 유량측정에 도입하여 중간단면적법, 지표유속법을 적용하여 통합드론측정시스템의 실용성을 검증 완료하였다. 2023년 현장에 18대의 통합 드론측정시스템을 도입하여 홍수기 유량측정에 활용할 계획이다.

Recently, various networks have been introduced in the car of the internal and external sides. These have been integrated by one HMI(Human Machine Interface) to control devices of each network and provide information service. The existing vehicle navigation system, providing GPS based vehicle positioning service, has been included to these integrated networks as a default option. The GPS has been used to the most universal device to provide position information by using satellites' signal. But It is impossible to provide the position information when the GPS can't receive the satellites' signal in the area of tunnel, urban canyon, or forest canopy. Thus, this paper propose and implement the method of measuring vehicle position by using the sensing data of internal CAN network and external Wi-Fi network of the integrated car navigation circumstances when the GPS doesn't work normally. The results obtained by implementation shows the proposed method works well by map matching.

Since more than 30 different information systems are collecting and providing construction related information, it is difficult for information users to figure out where and how to acquire the required information. Even if the user find the information, it is hard to meet users demand. Because the current systems accumulate the data just as administrative data and can do not connect the information from the different phases of the lifecycle for the specific facility. The information collected and managed in different information systems should be integrated in terms of lifecycle of the facility to improve money for value of public investment, the quality of life by improving quality of the facility and to provide the foundation for big data utilization in the construction industry. This paper suggested strategic planning for the development of the (assumed name) "The Lifecycle Integrated Construction Information Portal" as a foundation to use the data in construction industry, by investigating prerequisites and suggesting conceptual framework of the system.

In 2020, the Busan metropolitan library took the lead in establishing an integrated library system (ILS) that integrates bibliographic data from 49 public libraries and 103 small public libraries. However, each library still builds bibliographic data individually and repeatedly, and the bibliographic data built by each library is only physically stored in an integrated DB. Therefore the improvement in work efficiency or data quality has not been achieved. This study aimed to analyze the construction processes and quality of bibliographic data in Busan public libraries and to suggest a new implementation strategy for an integrated environment. To this end, (1) the construction process of bibliographic data was investigated, (2) the quality of the constructed bibliographic data was objectively analyzed, and (3) four implementation strategies were suggested based on critical problems. The implementation strategy aims not only to improve the quality of bibliographic data, but also to increase work efficiency and build an infrastructure for data sharing.
