Japan is a representative state where the volunteer fire brigade consisting of private citizens is well developed although it has an advanced fire fighting system established by local governments. Japan realized the limitation of response by governmental fire fighting system when large-scale natural disasters such as earthquake or typhoon and has developed and promoted several policies to activate the volunteer fire brigade. This study analyzes the policies of the volunteer fire brigade in Japan in detail and suggests policies which can be introduced to activate the volunteer fire brigade in Korea.

For the identification of the 3 dimensional dynamic characteristics of the Bongjeong Temple, the dynamic test for 1/3 scaled model was performed. Dynamic test with impulse excitation and vibration table excitation can provide useful data for the estimation of dynamic characteristics such as natural frequencies, damping ratios, mode shapes and stiffness center. This will complement the previous research from the 2-dimensional static test and provide the reference data for the enhanced structural analysis of the traditional wooden structures.

This research develops a methodology for standard design of spatial Database utilizing the disaster ethnography. Especially, the disaster response operation is sensitive to the size of the disaster, location, damage situation, resource a variability, etc. Moreover, there are many unknown and unexpected factors that will affect the disaster response strategy. But, the future Crisis Management Systems is needed that past disaster teaching. In another words, from now on the response systems need to prepare several scenarios and spatial data and manual etc. before the disaster. Then, this research is the experimental research which examined the relationship between the disaster-ethnography and the GIS spatial data of disaster.

최근 IT기술발전으로 데이터 저장 및 처리비용은 하락하고 소셜네트워크 서비스 등이 확대되어 데이터의 양적 팽창이 가속화되면서 빅데이터에서 가치를 창출하려는 시도가 늘어나고 있다. 특히, 국내 스마트폰 이용자가 3천만을 넘어서면서 모바일 기기는 대량 데이터 생산의 원천이 되고 있다. 모바일 기기는 스마트시대 대표 통신채널인 소셜미디어 활용을 가속화 시키며 다양한 분야에서 영향력을 발휘하고 있다. 특히 일본과 아이티 지진피해, 강남역 침수 등 재난발생 시 피해상황 파악 및 경보, 정보교환 등에 소셜미디어 채널이 활발히 활용되면서 새로운 매체로 떠오르고 있다. 본 논문에서는 언어분석을 통해 소셜미디어 속에 재난이슈를 모니터링하고 소셜미디어가 재난예방 및 대응에 적극 활용되기 위해 필요한 기술개발 방안을 제시하고자 한다.

지진, 호우, 태풍, 화재 등 긴급한 재난 알림 전달이 필요한 상황에서 청각장애인은 소리를 통한 알림을 인지할 수 없으며 문자를 통한 알림의 인지율도 비장애인에 비하여 상대적으로 낮은 편으로서 일반적인 수단의 재난알림을 신속하게 인지하기 어려운 경우가 많다. 이와 같은 청각장애인의 재난안전 긴급알림 인지의 취약성 문제를 해결하고자 픽토그램을 통한 재난안전 긴급 알림 시스템이 개발되었다. 본 연구에서는 재난문자 통보문의 문구를 기반으로 인공지능을 통하여 청각장애인이 인지하기 보다 용이한 일련의 픽토그램으로 자동으로 변환하는 기술을 개발하고자 하였다. 이를 위해 재난안전 관련 긴급 통보문과 관련되는 픽토그램 기반의 콘텐츠를 수집하고 문자 기반의 그림 출력에 적합한 인공신경망 구조와 훈련방법을 구성하여 인공신경망 기반으로 재난문자에 대응되는 픽토그램 기반의 청각장애인 재난안전 긴급알림이 생성될 수 있도록 하였다.

As a basic data to build a countermeasures against coastal disaster, the conscious survey of people living around the coastal are is needed. This study performed the conscious survey on 5 islands located at Korean southeast ocean including Youngdo of Busan. Among many respondents, 503 effective answers are got and followings are the analyzed results. Among the various kinds of disasters, especially the typhoon(28%), storm surge(19%), earthquake(15%) are selected as menacing disasters in mind to coastal inhabitants. Typhoon(60%) and storm surge(21%) were the representative disasters that the coastal inhabitants experienced. 67% among the respondents get the disaster-related information from TV and/or commercial medias, and other 21% depend on their own experiences. Although 33% of respondents attended the disaster-related training and the training time was less than 2 hours, they answered the training was very helpful. Over 85% among the respondents answered they will evacuate if a disaster occur, but only 19% know the evacuee shelter(s). Except the foods, various living goods are selected and willing to carry with for living at shelter if they have to evacuate.

this study, an expert AHP questionnaire analysis of public and private groups was conducted to take into consideration the requirements for realistic disaster services. Considered are public areas that manage disasters like fires and earthquakes that can be a major threat to national safety, as well as private areas that mainly develop disaster-related technologies. In the questionnaire, the public respondents valued accurate disaster situation information (ranked 4th and 6th) for citizens (1st), managers (3rd), and related organizations (2nd); the private sector highly valued the importance of three-dimensional (3D) control (ranked 1st, 3rd, and 5th) using future technologies. This study suggests the realization of a disaster-response service that meets the needs of public safety and technological innovation based on a 3D safety state information platform. We anticipate that this study will provide useful data for applying technology and for establishing detailed scenarios during the test bed and commercialization phases. We also expect that further studies will be conducted, such as the practical application and operation of realistic disaster response services, on the financial resources for the proliferation of local governments, and on policy support measures.

In order to evaluate the limit earthquake resistance of multi-story steel frames influenced by the strength and stiffness ratios of members, a series inelastic response analysis were carried out. From the analysis results, the damage distribution rules of multi-story steel frames were proposed. Conclusions are summarized as follows; 1)As the stiffness ratios of beam and column becomes small, the damage concentrates on the lower end of columns of the first story. 2) Considering the strength and stiffness ratios of the beam and column with weak beam type mechanism, the equations predicting the damage distribution of multi-story steel flames were proposed. 3) Through the equation which was supposed in this study, it is speculated that the damage distribution of the rigid or semirigid beam collapse type multi-story steel structure building can be predicted.

For free vibration of non-symmetric thin-walled circular arches including restrained warping effect, the elastic strain and kinetic energy is derived by introducing displacement fields of circular arches in which all displacement parameters are defined at the centroid axis. The cubic Hermitian polynomials are utilized as shape functions for development of the curved thin-walled beam element having eight degrees of freedom. Analytical solution for in-plane free vibration behaviors of simply supported thin-walled curved beams with monosymmetric cross-sections is newly derived. Also, a finite element formulation using two noded curved beams element is presented by evaluating elastic stiffness and mass matrices. In order to illustrate the accuracy and practical usefulness of this study, analytical and numerical solutions for free vibration of circular arches are presented and compared with solutions analyzed by the straight beam element and the ABAQUS's shell element.
