In these days, Disaster Management Systems have still put emphasis on its recovery more than the prevention of disaster events. However, the countermeasure of restoration has limitations to prevent the caused loss because the disasters often happen and are massive. Therefore, we propose a disaster prevention system for supporting the safe urban. In this paper, we try to construct a real-time monitoring system to prevent disaster events using new technologies such as Wireless Sensor Networks (WSN) and Geographic Information System (GIS). As a prototype to simulate the fire disasters on real-time, we construct gas sensors and temperature sensors. Our system consists of a WSN system to collect data of the gas and temperature sensors and to monitor the situation information. Our contribution is to provide a prototype application to prevent the disasters from the fire by constructing a WSN system with gas and temperature sensors.

The accident which is caused by the press work remains a Permanent obstacle in worker's hand or arms, the disaster ratio is high and the fatal case is many. Mainly Like this accident occurs because the hand to enter with inside of the press die, therefore, basic countermeasure is the safety press. In order to prevent access to mechanical moving part by the hand or any part of the body, it is important to making a safety die design Structurally. It presents the design of the safety press die with suitable structure in the Product's attribute which it had shown in samples, There is a possibility of being difficult because the attribute of safety die design that had present all the productions from research does not agree each other. but because the representative process which is used most at sample had designed, If you were imitates with safety die design base which is presented from this research, It comes to be thought to be the part which can are used at the various sides.

As ISO22301 (Societal security-Business continuity management systems-Requirements) related to BCM (BCP) was established in May 2012, KS A ISO22301 (National Standards) will be enacted at the end of the year. Foreign certification agencies at home and abroad are expanding their business, accordingly. And it is expected that there will be a trade barrier such as a demand for compliance with the Standards in the trade between companies. Hence I am trying to find the countermeasures of domestic companies and ways to invigorate Top Company Certification System in the reduction law (The Legislative bill on the support of voluntary activities of enterprises for disaster reduction).

Lately, much researches for information management of web GIS base are gone. Specially, disaster Information Management System development of Web-Based for management and offer of disaster information such as flood or earthquake is necessarily necessary for prevention and countermeasure about disaster, disaster information acquisition of interest area. Spatial DB access for plan/analysis/management business of this system should be possible and must become display of disaster information and disaster mapmaking through internet for disaster prevention but research of web GIS base about this field is childhood yet. This research executed research for disaster information offer using HTML and Javascript and ESRI's ArcIMS that is development tools or web GIS. And this research could search disaster information of interest area through various kinds function and offer in display through user selection. Also, topography of interest area could confirm through third dimension topography model who use VRML. And this research could supply disaster information of Chunchon city using various function thorough system of Web-Based.

The Roads in Gangwon Province generally was made on purpose to use the military road. In case of these roads, tremendous dangerous cut slopes do exist and its road linear shape was badly designed. In order to make up for this situation, the government has continuously established the new road or performed the public works such as the straight line of the curved road. Soksil 2 cut slope was made through the road improvement work. This has small surface failures and collapses. In spite of dry season, this slope are leaking lots of groundwater at the unbelievable point. So as to get curious phenomenon right, we performed a detailed field investigation, the geomorphological analysis, the stability analysis considering field characteristic and ultimately proposed the countermeasure to make sure stability of Sokil 2 cut slope.

Various disasters have been continuously occurred in Korea from 1990s to now. However, there is no substantial improvement against damages as compared with the past due to various reasons such as lack of fundamental recognition, ineffective response systems and widespread insensitivity to safety. More worse, new types of disasters have been frequently generated due to rapid changes in social structures and industrial development, unusual changes in weather and changes of international situations. These disasters request comprehensive countermeasures. In particular, while material damages by disasters can be recovered, the losses of precious lives cannot be recuperated in any ways. Thus, it is critical to set effective disaster medical plans. The first way to minimize damages by disasters is the prevention and the next is to set the disaster medical plans focusing on preliminarily activating the emergency medical system to rapidly rescue and take appropriate emergency medical services for casualties in the early stage when any disaster occurs. Nevertheless, no sufficient researches or references do not exist up to now. Even worse, effective emergency medical systems that play critical roles in increasing survival rates of casualties in actual disaster areas is not deployed. For the United States, the consistent countermeasure system is established in FEMA through a close cooperative system with relevant organizations for serious accidents including terrorists' attacks or natural disasters. For the emergency medical services in disasters, the disaster medical plan is set to cope with any disasters in perfect order by special area as operating the National Disaster Medical SystemESF#8 Role by FEMA. Accordingly, we need to set the extensive and integrated disaster prevention system for rapid and flexible operation against various kinds of serious accidents. This study identified overall problems in disaster control plans in Korea and suggested how to improve the emergency medical service system in disaster areas. Furthermore, it aims to prepare the basic data to set the effective emergency medical service plans when substantial casualties break out and more reasonable and systematic disaster control plans to cope with the future occurrence of serious disasters.

When the structure such as roadway, railway are constructed on abandoned coal mine area, the countermeasure to prevent settlements is necessary. In this study, numerical analyses are performed to evaluate the effect of the various countermeasures. As a results, the method which is filling the coal mine is more effective than that of reinforcing the ground above the coal mine. The ground settlement decreases hyperbolically with increasing the filling ratio of the coal mine. Also, the relationship between the filling ratio and the settlement reduction ratio is discussed precisely.

The subjects of the study are the sedimentary rock slope of the Mesozoic Gyeongsang Supergroup, which has a high risk of failure. The orientation of the slope-face represents a variety of changing characteristics. The rocks of the slope shall be sandstone, siltstone and dacite, and discontinuities shall develop beddings, shear joints, extension joints, and dacite dyke boundary planes. The type and scale of failure varies depending on the type of rock and the strike/dip of the discontinuities, but the toppling failure prevails. Based on the face-mapping data, SMR, physical and mechanical testing of rocks, analysis and review of the stereonet projections and the critical equilibrium analysis, all four representative sections required a countermeasure method because the acceptable safety factor during dry and rainy seasons were far below Fs = 1.5 and Fs = 1.2. After applying the countermeasure method, both the dry and wet conditions of the slope exceeded the allowable safety factor. In particular, the face-mapping data of the slope-face, the geological cross-sections of several representative sections perpendicular to the slope-face, and the critical equilibrium analysis and the presentation of countermeasure methods that have been reviewed based on them are expected to be reasonable tools for the slope stability. In addition, it will be possible to use it as basic data for performance evaluation for slope maintenance.
