With the increasing needs on various leisure activities, the users of passenger ships and cruisers have been increased year by year. Although over 15 accidents per year betide on domestic passenger ships for last decade, the researches on the safety of crews and guests on boards are difficult to find. This study performed the comparative analysis by experiments on the evacuation characteristics between experience levels on board a training ship. The followings are the results. From the seniors' experiments, it is found that more various evacuation scenarios have to develope and drill as a part of education contents. And from the freshmen's trials, the importances of the evacuation education and the roles of existing crews on evacuation guides are pointed out as to increase the safety of new crews and/or guests who are not accustomed to onboard a ship. On the other, it is explained that the communications between evacuees are worthy and useful, and also save more evacuation times. And on the viewpoint of evacuation methodology, it is clear that captain and evacuation-related crews have to control all the evacuation passages and evacuees of each passages to save more lives.

The purposes of this study are to propose architectural design and evacuation management guidelines for child care center with disabilities. To achieve these purposes, the questionnaire has carried out for director who manage child care center and analyzed the architectural characteristics of child care center for children with disabilities. The results of this study are as follows : (1) 65.3% directors think that less than 30% of children with disabilities in child care center can evacuate by oneself, and 73.2% of child care centers have difficulties for safe evacuation because of more than 50% of children with complex disabilities. (2) The moving or visual impaired children who live more than 2nd floors are need safe refuge areas for waiting in child care centers. (3) The child care centers for children with disabilities which were renovated from housing and multi-family housing have difficulties in vertical evacuating, and needs renovating for promotion of convenience and evacuation of children with disabilities.

Currently, South Korea is exposed to various attacks of North Korea such as traditional, nuclear, and ABC weapons. Now it is hard to make an accurate estimate the damage may have been occurred to citizens due to those attacks. It is only possible to assume the rough outline. As a countermeasure to such military threats of North Korea, government-aided evacuation facilities services are going along across the board concerning the object, installation range, budget, and drawing standards. Whereas, in case of public evacuation facilities, there is no special regulation or principle in designation. Since various facilities are regarded as applicable, any protection against military threats can't be anticipated. In this study, military threats provoked by North Korea are figured out, thus the problem of plan and design that public evacuation facilities have are pointed out. This study suggest the result and proposal.

Lately, losses and damage from natural disasters have been increasing. Researchers across various fields in Korea are trying to come up with a response plan, but research for evacuation plans is still far from satisfactory. Hence this paper proposes a model that could find an optimized evacuation route for when disasters occur over wide areas. Development of the model used methods including the Dijkstra shortest path algorithm, feasible path method, genetic algorithm, and pareto efficiency. Computations used parallel computing (SPMD) for high performance. In addition, the developed model is applied to a virtual network to check the validity. Finally the adaptability of the model is verified on a real network by computating for Gumi 1stNational Industrial Complex. Computation results proved that this model is valid and applicable by comparison of the fitness values for before optimization and after optimization. This research can contribute to routing for responder vehicles as well as planning for evacuation by objective when disasters occur.

This study focused on the emergency evacuation guidelines considering the behaviors of people with disabilities in Korea. For these purposes, this study reviewed the movement behaviors of people with disability and the treatment characteristics of emergency and hazards in United States. The results are as follows. First, it is necessary to suggest establishment requirements and building design guidelines considering the behaviors of inhabitants and the occupant load in social welfare facility for people with disabilities. Second, it is important to establish disaster preparedness and evacuation planning in emergency and hazards reflecting the movement behaviors of people with disabilities in national organizations and institutions on disability. Third, periodical emergency and fire drills are necessary for people with disabilities and should be managed considering the impaired prototypes, evacuation aids and service animals.

Emergency and evacuation planning is critical to reduce potential loss of life from flooding. In order to develop evacuation plans, emergency managers and decision makers require estimates of probable inundation areas and times of inundation. In this paper, we present an agent-based modeling approach that incorporates in a hydrodynamic model to estimate both of these properties. A case study is conducted modeling the failure of a dam located in Andong, South Korea. We estimate flood travel times for Manning's roughness coefficients and discharge using a coupling of the continuity equation and Manning's equation. Using the output from the hydrodynamic model and the flood travel times, the agent-based model produces flood inundation maps at each time interval. The model estimates that for two-thirds of the Andong region the time of inundation is estimated to be slightly less than three minutes. The results of this study can be used to in the development of emergency and evacuation planning for the region.

In Korea, fire hazard and risk analysis and response management planning related to existing decrepit buildings, including interior construction and architectural layout revision, due to various occupancy purposes have not been researched or established. Therefore, regulations and technical standards that can manage and reduce fire hazards and risks based on fire hazard analysis and evaluation are required. This study was performed based on a site survey and fire evacuation assessment including performancebased analysis in 3 actual existing buildings to find the life safety issues and provide improvement recommendations.

Every year, many people are severely injured or lose their lives in accidents such as fire, chemical spill, public pandemonium, school shooting, and workplace violence. Research indicates that the fate of people in an emergency situation involving one or more hazards depends not only on the design of the space (e.g., residential building, industrial facility, shopping mall, sports stadium, school, concert hall) in which the incident occurs, but also on a host of other factors including but not limited to (a) occupants' characteristics, (b) level of familiarity with and cognition of the surroundings, and (c) effectiveness of hazard intervention systems. In this paper, we present EVAQ, a simulation framework for modeling large crowd evacuation by taking into account occupants' behaviors and interactions during an emergency. In particular, human's personal (i.e., age, gender, disability) and interpersonal (i.e., group behavior and interactions) attributes are parameterized in a hazard-impacted environment. In addition, different hazard types (e.g., fire, lone wolf attacker) and propagation patterns, as well as intervention schemes (simulating building repellent systems, firefighters, law enforcement) are modeled. Next, the application of EVAQ to crowd egress planning in an airport terminal under human attack, and a shopping mall in fire emergency are presented and results are discussed. Finally, a validation test is performed using real world data from a past building fire incident to assess the reliability and integrity of EVAQ in comparison with existing evacuation modeling tools.

Most of the Historic Preservation Areas are very vulnerable to disasters. The aim of this study is to build probability of street blockade for evacuation routes planning from each house to an evacuation place at a large-scale disaster in such a historic preservation area. The study area is Hamanaka Machi Happongi Shuku in Kashima city, Saga Prefecture, which has been designated as a preservation district of traditional buildings. To achieve this aim, we referred to the formula for probability of street blockade for normal city area made by Tokyo Fire Agency. We revised it, considering the width of street under 4 m, structure of houses along the street, and the distance from the house to main street with the width over 4 m. Then, we applied the revised formula to the study area.
