Korea is experiencing various disasters both natural and artificial. This study is descriptive research designed to examine the perception of the disaster response ability of fire-paramedics during the response stage of disaster management. The subjects of this study were EMT-P's who had more than 2 years of experience in the field at a fire station in G Province. The questionnaire, including the items for the sub-factors of the field response ability, were prepared and 161 final questionnaires were collected and analyzed with the SPSS program. The mean scores of triage ability, patient treatment ability, patient transfer ability, disaster support ability, and disaster response speed were 3.53, 3.68, 3.66, 2.95, and 3.44, respectively. As a result of multiple regression analysis, variables affecting the speed of disaster response were in the order of patient treatment ability, patient transfer ability, and disaster support ability. In conclusion, fire-paramedics will have to consider the ability to treat patients, transfer patients, and disaster support to improve disaster response speed, and, ultimately, disaster response guidelines should be developed to improve disaster response capabilities.

The research of psychological supporting systems as safety and welfare for disaster victims damaged psychologically as well as physically by a sudden disaster to return to effectively their social life has been carried. The domestic National Emergency Management Agency(NEMA) is operating the Disaster Victim Psychology Support Center that helps with curing damaged psychology and studies the transmission system of psychology management services, the classification of victims for disaster psychology support, and emergency consultation method to systemically support disaster psychology management. However, current psychology supporting centers provide the simple information for supporting centers such as medical and social welfare organizations. The development research of IT-based management systems to obtain needed information to construct the proposed systems curing psychological damage is still primitive step. Therefore, this paper shall propose a GIS-based integrated management system for victims and managers to effectively share related information one another and to return to victims' social life as soon as possible. Also, we implement a simple prototype system based on the Web. The proposed system supports the spatial search and statistical analysis based on map as well as keyword search, because having the location information on disaster victims, damage occurrence places, welfare and medical institutions, and psychological supporting centers. In addition, this system has the advantage reducing the frequency of disaster damage by providing aids in making efficient policy systems for the managers.

The reason of source for a tragic death by the occurrence of an event is $\ulcorner$unobservant of safety rule,$\lrcorner$ $\ulcorner$negligence of staff,$\lrcorner$ $\ulcorner$deficiency of responsibility$\lrcorner$ and $\ulcorner$deficiency of safety value$\lrcorner$ and for certain reason that is insufficiency of space for safety education also think little of a people, unobservant of safety rule, selfishness and so on. It makes new and specific plan that is simulation room before I compare the inside and outside of the country for a nation the reform of consciousness. Next, go ahead with a plan for about safety-simulation room. The Government can support to plan if it make a proposal to center of Government. It should be make a people of safety system, and it build the safety-simulation room $1{\sim}2$ in the city or county. And, the city cannot build the big safety-simulation room the reason are size of building and money. Accordingly, it will be make a system and installation for different type of safety-simulation room for about calamity, disaster and different type of accident in Korea. It must be build the building of space that should be make a space of knowledge and information by many books and media, develop of education program from life-safety.

The average growth in the wind power energy market during the past five years has been 26% per year. Renewable energy resources, of which wind energy is prominent, are part of the solution to the global energy problem. Wind power system and the rotor blade concepts are reviewed, and loadings by wind and gravity as important factors for the mechanical performance of the materials are considered. So, the mechanical properties of fiber composite materials are discussed. In addition, it is necessary to analyze and evaluate the stress distribution and deformation for them in the design level. This study shows the result that CFRP rotor blade of wind turbine satisfies the strength and deformation through numerical analysis using the commercial finite element analysis program.

Wind power system is composed by 3 major parts, rotor blade, nacelle and tower. Especially, the nacelle cover has an important role to prevent the component of nacelle and rotor from an extreme external circumstance. Therefore it is necessary to analyze and evaluate the stress distribution and deformation for them in the design level. There are two major points in nacelle cover analysis. The one is nacelle cover itself and the other is cover support structure. According to GL specification, this study shows the result that CFRP nacelle cover of wind turbine satisfies the strength and deformation through numerical analysis using the commercial finite element analysis program.

In terms of deregulation requests from business, incidents at construction sites are rapidly increasing after reducing the regular safety training hours. Especially, to prevent incidents through safety trainings for construction site workers, who have lots of hazardous tasks than general manufacturing, is not only to protect property of both the companies and the country but also to increase their profits. That is why there are loud voices regarding that the safety training is a core mandatory to prevent industrial incidents. But, most companies, as soon as the deregulation for safety training is implemented, mitigated conducting safety trainings to prevent incidents. With this, the incidents are currently to be increased and caught in a vicious circle of many incidents at the smaller companies because of their absentmindedness regarding safety training due to their poorness as subcontractors of major companies, comparing to major companies. This study explains that the difference between managers and workers are existing about safety awareness and knowledge. And, we confirmed that the educational factor led by deficiency of safety awareness and knowledge was the major factor.

With regard to industrial accidents, large corporations and public institutions are continuously reducing disasters through systematic management. However, industrial accidents continue to increase in small-scale workplaces. In order to ensure the safety of workers, the government supports the purchasing of industrial accident prevention equitments through financial support projects for small business. However, despite the financial support, the effectiveness of the project is hardly verified. In this study, we analyze the policy effectiveness of the financial support program for industrial accident prevention in a small-scale workplace using the difference-in-difference method. To achieve research purposes, we used the data on the occurrence of industrial accidents, the status of workplaces by year and the data on the status of workplace benefiting from financial support program for the past 10 years. This study is significant in that it analyzed the net effect of financial support programs for disaster reduction in the small business site.

The permeability coefficient is an essential parameter for the study of seepage flow in fractured rock mass. This paper discusses the feasibility and application value of using readily available RQD (rock quality index) data to estimate mine water inflow and grouting quantity. Firstly, the influence of different fracture frequencies on permeability in a unit area was explored by combining numerical simulation and experiment, and the relationship between fracture frequencies and pressure and flow velocity at the monitoring point in fractured rock mass was obtained. Then, the stochastic function generation program was used to establish the flow analysis model in fractured rock mass to explore the relationship between flow velocity, pressure and analyze the universal law between fracture frequency and permeability. The concepts of fracture width and connectivity are introduced to modify the permeability calculation formula and grouting formula. Finally, based on the on-site grouting water control example, the rock mass quality index is used to estimate the mine water inflow and the grouting quantity. The results show that it is feasible to estimate the fracture frequency and then calculate the permeability coefficient by RQD. The relationship between fracture frequency and RQD is in accordance with exponential function, and the relationship between structure surface frequency and permeability is also in accordance with exponential function. The calculation results are in good agreement with the field monitoring results, which verifies the rationality of the calculation method. The relationship between the rock mass RQD index and the rock mass permeability established in this paper can be used to invert the mechanical parameters of the rock mass or to judge the permeability and safety of the rock mass by using the mechanical parameters of the rock mass, which is of great significance to the prediction of mine water inflow and the safety evaluation of water inrush disaster management.

About one hundred twenty thousand ($\pm$twenty thousands) people are wounded and about two thousand persons are dead from industrial accidents in Korea ［1］, Therefore, Korea is notoriously called as a haven of disaster. This study investigated the safety situation of industries and attitude of safety managers to reduce the occurrence of accidents. The period of investigation was during March through August, 1977. Two hundreds of safety managers were replied, but replies of 183 were used because some of them were inappropriately answered for the questions. Their replies were analyzed by SAS program. As a result, only three persons out of 183 managers were women, 83% of them are married, 25.1% were graduated from university, 15.2% were graduated from two-year college. Full time safety managers were only 8% of them. Safety managers who have experienced injured before their current position were 26.3%. This confirms that company allocated injured persons to a safety department. Korea also needed an educational agency like NIOSH and a punishment agency like OSHA in USA［5］. These agencies can solve a fundamental problem of safety management for small-and-medium size industries. Furthermore, a new safety management bureau for controlling these two agencies will be necessary to reduce accidents in near future.
