반복되는 재난을 효과적으로 대응하기 위해서는 과거에 수행한 재난 대응 업무로부터 생산된 기록들의 체계적인 관리가 무엇보다도 중요하다. 흩어져 있는 재난안전 기록정보자원을 기록관리체계로 편입하기 위해서는 먼저 기능분류체계(BRM) 개발이 필요한데, 본 연구에서는 이를 위한 선행 연구로 위기관리 표준매뉴얼(SOP)을 대상으로 재난안전 공통업무를 분석하였다. 총 28개의 매뉴얼을 대상으로 3차에 걸친 분석을 실시하였으며, 그 결과 1,667개의 주요업무가 추출되었고 이는 다시 5개의 중분류 유형, 20개의 소분류 유형으로 그룹핑되었다. 나아가 업무유형별 생산 예상 기록을 살펴봄으로써 재난안전 업무의 수행 및 재난안전 기록정보자원 관리 측면에서 시사점을 도출하였다.

To efficiently attenuate seismic responses of a structure, a novel pneumatic-driven active dynamic vibration absorber (PD-ADVA) is proposed in this study. PD-ADVA aims to realize closed-loop control using a simple and intuitive control algorithm, which takes the structure velocity response as the input signal and then outputs an inverse control force to primary structure. The corresponding active control theory and phase control mechanism of the system are studied by numerical and theoretical methods, the system's control performance and amplitude-frequency characteristics under seismic excitations are explored. The capability of the proposed active control system to cope with frequency-varying random excitation is evaluated by comparing with the optimum tuning TMD. The analysis results show that the control algorithm of PD-ADVA ensures the control force always output to the structure in the opposite direction of the velocity response, indicating that the presented system does not produce a negative effect. The phase difference between the response of uncontrolled and controlled structures is zero, while the phase difference between the control force and the harmonic excitation is π, the theoretical and numerical results demonstrate that PD-ADVA always generates beneficial control effects. The PD-ADVA can effectively mitigate the structural seismic responses, and its control performance is insensitive to amplitude. Compared with the optimum tuning TMD, PD-ADVA has better control performance and higher system stability, and will not have negative effects under seismic wave excitations.

우리나라는 최근 세월호 사건을 계기로 총체적인 국가안전체계 부재라는 사실에 직면해 있으며 정부와 국민 모두에게 큰 경각심과 충격을 주었고 국가적 차원에서의 일원화된 재난통신망 구축과 재난대응관리에 대한 법, 제도, 조직 개선 및 선진화된 재난대응표준절차의 수립이 절실히 필요하게 되었다. 이를 실현하기 위해 PS-LTE 방식을 이용한 통신망 구축이 최적의 방법이며, 700MHz 주파수 대역을 이용하고 동시에 재난대응 관리 측면에서도, 재난관리 표준운영절차 선진화, 개방형 플랫폼 형태의 재난통합대응체계 구성이 필요하다. 효율적인 재난통신망 구축을 위해서는 자체망 구축과 임대망을 혼용하여 사용하는 것이 효과적이며 약 5조 2천억원의 비용이 소요될 것으로 추정된다.

정보통신기술을 활용한 스마트한 재난관리체계는 가장 빈번하게 발생하는 자연재난과 교통사고 범죄 같은 사회적 재난에 충분히 대비할 수 있고 피해를 줄일 수 있는 한 방안이라고 볼 수 있다. 언제 어디서 어떻게 일어날지 예상할 수 없는 재해에 대비하기 위하여 무엇보다 중요한 것은 적절한 위기의식과 재난 초기의 올바른 선택과 대응일 것이다. 본 논문은 향후 국내 재난안전 부문에서 소셜 네트워크 서비스를 효과적으로 활용할 수 있는 방안을 모색하고자 한다. 이를 위해 해외의 재난안전 분야에서의 성공적 활용 사례를 소개하고 우리나라에 적용 가능한 방안을 도출하고자 한다. 결과적으로 유비무환의 자세로 종합적이고 체계적인 재난관리체계를 도입한다면 피해의 최소화와 신속한 재해복구에 효과적으로 기여할 것이다.

In this paper, we propose a method to investigate the safety consciousness of a analyst incident response. This study conducted a statistical survey on 154 analysts who hired as expert in environment monitoring organizations in South Korea. The results of the analyses showed that respondents had good awareness on the equipment incident response and complied with laboratory safety regulations very well. Secondly, respondents were aware of the importance in the order of equipment incident response, an analytical laboratory incident response, and the cause of a chemical substance associated incident in an analytical laboratory in regarding the regulation compliance for creating a safe laboratory environment and the securement of laboratory safety. Therefore, (it was identified that) it would be necessary to create a safe environment and integrate a safety management system.

The scale of disasters is very large, also the influence of disasters is irreversible. Korean people has continuously learned how to deal with disaster management law. However, as time goes by after the many disaster, the concern with the disaster management by the people seems to become old and banal topic which nobody has interest in. If so, can it be said that our society is safe from the disaster? This study start from critical mind of asking this question. This study puts an emphasis on the problems such as following; To realize whole concept of disaster management provided in the basic civil defense law, the combined disaster management should be required to be established, the combined law should play a integral part for prevention for the disaster and should be a concrete basis of various laws for disaster management. Establishing a consolidated organization for disaster managing and united response organization is necessary. This consolidated organization is not temporary one such as civil disaster control headquarter but permanent one such as Disaster Management Office which controls an over all aspects of disaster management. Temporary organization should not be divided into natural calamity and man-made calamity but integrated one as a single control tower for all sorts of disasters. The police and army under fire fighting system should be reconsidered. It is necessary to make leadership system on the disaster place more substantial centered around present fire fighting system. To do so, more clear division of duty is required. The working condition should be improved so that all public servants in this agency can play their roles with pride and worth. The resource owned the existing administrative organization must be used by an appointment system. And to manage a large scale of disaster, it is necessary to have interorganizational network system which many specialized organization including volunteer group are integrated. And the natural disaster happen, many professionals and volunteers are distributed to the spots of disaster in the right man in the right place. Finally, citizen's consciousness about safety supervision needs to be recover.

최근 강우에 의한 자연재해 발생은 특정지역에 발생하던 형태에서 전국 어디든 발생할 수 있는 형태로 변형되었으며, 이에 대한 피해도 날로 증가하고 있는 추세다. 이러한 재해발생은 사회경제적, 재정적, 물질적 및 인명손실에 많은 영향을 초래하고 있으며, 이를 위한 체계적인 관리기반 확립 및 시스템적 해결방안 제시를 위한 모델적립이 필요한 단계라 할 수 있다. 이에 본 연구에서는 재해의 유형을 분석하고 정리함으로서 보다 과학적이고 신속한 재해업무 계획 및 수립을 위한 시스템 설계를 실시하였으며, GIS기법을 활용함으로서 의사결정에 필요한 기초 자료를 제공하고자 한다. 또한, 각 시군에서 구축하고 있는 수치정사영상 및 수치표고모형을 활용하여 실제적 지형형태 및 상황을 분석하여 현황에 맞는 재해관리 업무 수행을 위한 관리시스템을 구축함으로서 현실적 사용에 근접한 관리시스템을 구축하였으며, 수치정사영상과 수치표고모형을 OpenGL을 이용하여 3차원 도시하고 단면분석 모듈을 개발하여 상황발생 부근의 지형형태 및 종단면을 화면에 도시하고 분석하도록 시스템을 구축하였다.

Site response analysis is an important topic in earthquake engineering. A time-domain numerical method called as one-dimensional (1D) finite element artificial boundary method is proposed to simulate the homogeneous plane elastic wave propagation in a layered half space subjected to the obliquely incident plane body wave. In this method, an exact artificial boundary condition combining the absorbing boundary condition with the inputting boundary condition is developed to model the wave absorption and input effects of the truncated half space under layer system. The spatially two-dimensional (2D) problem consisting of the layer system with the artificial boundary condition is transformed equivalently into a 1D one along the vertical direction according to Snell's law. The resulting 1D problem is solved by the finite element method with a new explicit time integration algorithm. The 1D finite element artificial boundary method is verified by analyzing two engineering sites in time domain and by comparing with the frequency-domain transfer matrix method with fast Fourier transform.

Post-earthquake risk assessment technique in Korea is developed in 2013 by National Disaster Management Research Institute, at the same time, related manual and standard regulation is distributed to every local government by National Emergency Management Agency. The objectives of this research are to investigate and evaluate the post-earthquake risk assessment of 9.12 Earthquake (M5.8, Gyeongju City, 2016) and 11.15 Earthquake (M5.4, Pohang City, 2017). To suggest and improve the assessment process of post-earthquake risk, first post-earthquake risk assessment method of advanced foreign countries including US, New Zealand and Japan are compared, and post-earthquake evaluation activities in 9.12 Earthquake and 11.15 Earthquake are analyzed. From the results, it is needed to expand the adapted building and structure types and strengthen the earthquake disaster response capacity of local government.
