This study refers to our lack of cognition about the limit of our own presumption ragarding natural disasters as meta-ignorance. It investigated how people tend to suffer from meta-ignorance regarding fire disaster occurred due to earthquake and then examined the effect of disaster simulation to mitigate the meta-ignorance. The result indicated the phenomenon of meta-ignorance: those who underestimate the level of the earthquake fire hazards tend to underestimate the possibility of occurrence of situations exceeding his or her estimation. It was also found that meta-recognition regarding one's own presumption about earthquake fire was associated negatively with the tendency of dependence on government for disaster prevention. Furthermore, it was shown that the presentation of disaster simulation has an effect to reduce the tendency of meta-ignorance.

 The role of local government officials in emergency period after disaster occurred is exceedingly important. It is necessary for effect responses to prepare the emergency operations plan before disaster occurred. This study examines perceptions of local government officials related to business continuity plan. The research area is Naruto City in Tokushima Prefecture. The questionnaire survey was conducted to Naruto City local government officials. Question items are perceptions of emergency response issues and important operation contents associated with Nankai Trough Earthquake. In the analyses, each item was aggregated and their structures were pictured based on pass analysis. The results shows that local government officials recognized importance of resources related to life in emergency period and living materials for the support service. Another results indicate that perceptions of emergency response issues and important operation contents are mostly related, on the other hand a little part are not found relevant.

 In a large scale disaster, regional organizations must strategically cooperate with the others to recover and reconstruction disaster regions. A District Continuity Plan (DCP) and its action plan are required for each organization to facilitate cooperative actions after a disaster. However, to build consensus among DCP developer is difficult because important bases of the organization are different. In order to solve the problems, it is effective a decision support system which enable to present a specific recovery plan for action plan. In this study an attempt is made to propose a District Impact Analysis (DIA) method using a genetic algorithm and a concept of the development action plan based on live design. Several recovery planning of road access and logistics functions are presented to demonstrate the effectiveness and applicability of the proposed method.

 For emergency responses, it is necessary to prioritize the district continuity response by strategically coordinating local organizations. It is necessary to establish a guideline, with the presumption that the entire region prioritizes the district continuity, and to consensually decide structural measures and recovery sites ahead of time, so that each organization could strategically implement the action in the event of an emergency. This strategic plan is the DCP, and the plan needs to be formulated ahead of time.
 In this study, a definition of DCP in the event of a large-scale flood disaster is provided.

 It is difficult to judge and forecast flood risk on small-medium rivers, because the risk is related to various local factors such as channel network and land use. In this research, high-resolution flood inundation analysis model was utilized to confirm details of flood risk and a result of the analysis is transformed to local disaster information which is familiar to inhabitants (Local weather information). An availability of this method is checked and its relations to weather information are evaluated. As an example, this research taked an event of the Okuetu heavy rainfall, which happened on September in 1965 around Oono City and caused heavy damages. The practical disaster education with the local disaster information based on the results of flood inundation analysis was provided to some students in Yushunishi elementary school in Oono and we have checked the effect from the pre/post questionary surveys.

 In case of emergency, we should act according to disaster prevention manuals that are usually provided beforehand. However, in many cases, as time passes, we forget the measures in case of emergency as it rarely occurs. Also, in order to act correctly in an emergency, emergency training is indispensable. As checking before action cannot be secured in case of emergency, it is important that each person involved must remember and act with certainty. In the present research, an attempt to include emergency practices in the daily routine was made and measures were proposed. Finally, the effectiveness of the trial was confirmed through a questionnaire.

 This study attempts to evaluate the effectiveness of earthquake preparedness to the improvement of regional resilience by analyzing the reliability of road network based on the safety of human life. This reliability analysis extracts vulnerable points to the reachability of fire truck and ambulance and the evacuation of residents. By comparing the reinforcement of extracted elements with the ongoing plan, this paper demonstrates that the proposed preparedness based on the regional resilience more improves the safety of residents with the enhancement of the continuity of road network. The assessment of earthquake preparedness from various viewpoints is necessary to predict and minimize the seismic crisis. In this paper, it was implied that the evaluation that put a priority on the human life could be a criterion for the improvement of regional resilience.

 On the basis of some instructions of the East Japan Grate Earthquake Damage, it is required for the local government that the BCP is shoud be made to keep main important functions in out of supposition. Even if the functions fall into be faires, it is required to recovery as soon as possible. In this paper, the concept of BCP and disaster mitigation as well as disaster prevention for local government based on 4 disaster resilience indices such as “robustness”, “redundancy”, “resourcefulness”, “rapidness”. Furthermore, it considers loading a resilience engineering function (four capability, respond, pay attention to, anticipate, and study) on the problem of reservation of the resource which becomes important for disaster developmental time. And the governmental agency BCP decision technique in which the effectiveness by construction of resilient organization control is high is proposed.

 In Japan, we have more than 600,000 drag-shovels and the death labour accidents relating with drag-shovels happened more than 70 per a year until 2006. So that we analysed the accidents relating with drag-shovels in details. As a result, there are 4 types of labour accidents: a drag-shovel falls down due to its unstable condition, a burden hanged hits a worker, slope or trench collapses due to excavation and weight of a drag-shovel, a drag-shovel drives backward or pivots and hits a worker. It is revealed that a drag-shovel becomes unstable condition due to dynamic operation such as driving forward or pivoting in a slope and that a drag-shovel and worker are working together within the maximum excavation radius of the drag-shovel. As the countermeasure for the safety, we recommend the use of a drag-shovel with ROPS (Roll-Over Protective Structure) and fastening a seat belt, to set the maximum stable grade considered with dynamic operation, the system alerting both an operator and worker to their approach.

 Deaths resulting from falling accidents account for 40% of all labor-related deaths in the construction industry and outnumber deaths from any other cause at construction work sites. Measures to reduce accidental falls from working surfaces other than scaffolding are of the highest priority. This paper details a survey (questionnaire) of companies to ascertain the equipment they actually use to prevent falls from construction work sites on slopes. We collected basic data and engineering findings useful for preventing falling accidents through construction safety management on “cliffs and slopes, ” the major working surfaces, apart from scaffolding, from which falling accidents occur. We also identified issues to consider in the future based on the results of the survey and past accident analyses.

 This paper treats an evacuation behavior simulation from inundation. We calculate a expansion of flood flow with 2-dimensional unsteady flow model, and the emergency evacuation behavior from the inundation is simulated by using Multi-agent model. Multi-agent modeling is a computational method that allows building an artificial environment populated with agents which are capable of interacting with each other. In this paper, we investigate the influence of the physical environment and the properties of evacuees on the evacuation results. Through the simulation and the analysis by design of experiments, it is shown that the existence of evacuation building to evacuate temporarily besides the evacuation center is effective for a inundation disaster.

 Slope disasters such as slope failures often occur in Japan due to various natural phenomena. Shotcrete and other slope works are carried out to protect social infrastructure and dwellings from slope disasters. Lifelines and safety belts are used to prevent falling accidents and ensure the safety of the workers who engage in slope works. A number of standard lifeline fixing methods are widely used and reported, but their engineering rationale is unclear. In the present study we considered the proper diameters, driving depths, and shapes of the anchors used to fix lifelines, in order to prevent friction and wear of the lifelines and better maintain safety during work on slopes. This paper reports the results of an impact loading experiment performed with experimental banking simulating a construction work site on a slope.

 For effective maintenance and management of pipeline system, it is necessary to evaluate not only the damage of pipe materials but also the detection of pressure waves such as water hammer. In this study, non-destructive inspections of pressure waves are proposed by applying acoustic emission (AE) and image analysis. Thus, pressure waves were detected in the model pipeline system, based on control of valve closing time (0.40-10.48s). The AE behavior of pressure waves were dependent on the degree of maximum pressure scale and could be evaluated applying AE parameter analysis. Using digital image correlation method (DICM), a relationship between maximum pressure level and displacement is correlated. By monitoring the pressure waves in model pipeline based on these results, the generated pressure waves was successfully detected by non-destructive inspection methods.
