For necessary information sharing or operation control via wire-wireless/mobile network connecting of devices at disaster area in greatest need of attention, an emergency network efficient construction method quickly connecting nodes within specific range using Delaunay triangulation is proposed. The emergency network constructed by proposed method shows the same aggregate network length, but does more excellent performance in term of network construction time the more long max length connectable to adjacent node as compared with the network by naive method. In experiment of 1000 input terminal nodes, 5 max length connectable to adjacent node, our proposed method enhances 89.1% in execution time without network length increase compared to naive method. So our method can go well to many useful applications as shift construction of communication network of adjacent devices, internet of things and efficient routing in the sensor network in continuous improvement of communication capability.

High capacity UPS and emergency generators are commonly employed at facilities where power interruption is not allowed. Nowadays, combinations of existing commercial incoming power and an emergency generator or combination of multiple generators and CTTS(Closed Transition Transfer Switch) is adopted sometimes for more reliable power supply. In this paper, application of CTTS and STS(Static Transfer Switch) to dual-power line is suggested for highly reliable uninterruptible power. By realizing such a system, construction of incoming power facilities, installation of emergency generator and large capacity UPS can be omitted, through which saving of the installation space and corresponding capital investment can be expected.

Recently, the regulation about HEE(horizontally installed emergency exit) established at upper 4story in apartment houses was introduced by revising enforcement degree of Building Act. HEE is a facility for egress to lower story through floor breach and ladder system so that it gives a useful evaquation way directly to an individual household in apartment when they failed to evacuate through the entrance door. HEE may offer an opportunity to optain two way egress path ways instead of evacuation space at balcony and through path way to adjacent household in building and that might be an big strengh. but it needs to guarantee for against the crime, getting detailed reviews for being security and supplementation of fire test methods.

In this research, we determine the proper number of entrances in the evacuation facilities for civil and military personnel. The current standards on the emergency evacuation facility only sets the number of possible evacuees and the according architectural floor area since the evacuation have been completed. However, other than static standards such as the floor area, there is needs to consider the dynamic standards along with allowable evacuation time such as the number of entrance, staircases and so on. Therefore, we need to consider the number of entrances and their location in order to account for the allowed evacuation time of particular number of people in a set area. The outcome could be contributed to the standards which should contain the dynamic conditions associated with evacuation.

The Railroad Safety Act was implemented in 2005 due to the increased concerns regarding railroad safety since the Daegu subway fire in 2003. In line with this, the Act became a standard to build the total railroad safety systems which has been overlooked compared to the quantitative growth of the railroad business. The minister of the ministry of Land, Transportation and Maritime Affairs lays down the Act for railroad Companies to conduct emergency programs in response to the emergency occurring on the railroad such as fire, explosion, derailment, etc. By enacting the Safety Act, the nation's construction of the contingency management system for railroad emergency increased", and it made the railroad company prepare the Emergency SOP by establishing 'The guideline on the Establishment of the railroad Emergency Plan' in order to support the efficiency of the Act. In line with this, I would like to analyze a matter of system development and the main function of the "railroad Emergency Training Program" for activation improvement of standardized operation procedure developed through the 'Total capitalize Safety Technology development'.

Although the railroad industry has progressed in terms of amount and quality because of the opening of the new express ways in 2004 and the construction and openings of the express railroads of cities, the establishment of safety has been poor so there has been lurking accidents and it resulted in big accidents like a Daegu subway fire. Therefore, this study is to minimize damages of life and property by establishing GIS, a map for emergency and Activity-Action and emergency reaction scenario through a web in case of emergencies mentioned before.

Today many people live in various risks due to rapid industrialization. High-rise buildings and underground facilities are increasing in the heart of the city. It probably would be developed into a gigantic disasters complicated with sudden climate change. To effectively cope with these disasters, National Emergency Management Agency was set up, but it has been pointed that the Agency's role is limited to treat the problems. Therefore, emergency management system and disaster case study were reviewed and analyzed. And a Proposals for Improvement of the National Emergency Management System based on Past Disaster Cases was suggested in this paper.

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.

Arbitration has grown a unique resolving method for international commercial disputes. However, it has considered a similar court process, such as interim relief, during arbitration proceedings. Further, it would be asked for urgent measures before the arbitrators are constituted in the proceedings. In this case, the disputing party has to apply in the court. This is an unattractive factor in international arbitration; therefore, some institutions are trying to reform such an inconvenient system by adopting the emergency arbitrator. The purpose of this study is to look into ways of utilizing the emergency arbitrator for effective dispute resolution in shipbuilding and shipping industries. The emergency arbitrator needs to solve problems such as making a decision on leaving cargos in the ship, matters involving a ship arrest, or issues regarding vessels under construction. In order to utilize the emergency arbitrator system, it needs to make a close partnership with related institutions, prepare Korean-style standard shipbuilding and shipping contracts, and provide training programs for new emergency arbitrators and staff of institutions. Next, the arbitration institution has to have a great working relationship with a court. Finally, it should try to implement a new system, such as on-line service, for the procedures of the emergency arbitrator.
