Recently, damage caused by natural disasters such as fire, earthquake, heavy rains and heavy snow is increasing. In addition, traffic accidents due to freezing, fog and fire in tunnels and bridges are frequently occurring. In such a disaster situation, it is very important to take prompt action by the person in charge of managing the facility and area.To this end, a disaster broadcasting system is used, but in the existing system, the broadcasting room and the speaker are connected by a wired connection. Also, the person in charge has to be in the broadcasting room to broadcast, which has a problem of delaying the time. In this paper, we design a disaster broadcasting system using LTE modem. The designed system enables a broadcasting person to make a call to a broadcasting system from anywhere using a cellular phone and a public telephone. Broadcasting via telephone is possible only with the telephone number pre-registered in the system and can be registered / deleted by the administrator. The registered telephone number, incoming voice file, and announcement voice for automatic broadcasting are stored in the system internal SD memory for convenient management. This disaster broadcasting system is expected to contribute to quick and convenient disaster broadcasting.

Since the late 19th century, the annual average temperature of the Earth has risen due to excessive emission of greenhouse gases, and abnormal weather phenomena such as heavy rain and heavy snowfall have been increasing frequently all over the world. In a city with high population growth due to high economic growth, fire and terrorist accidents can cause serious property damage and human casualties. The purpose of this study is to propose the need for evacuated facilities to protect victims, and suggest adequate shelters' size which can be protectable them. In spite of the Ministry of Public Safety and Security designated 3.3 square meters of per capita capacity, they does not specify the basis about setting this criterion.

On 7 December 2007, the Hong Kong registered tanker Hebei Spirit, laden with 209,000 tonnes of crude oil, was struck by the crane barge Samsung No 1, whilst at anchor about five miles off Taean on the West Coast in Korea. About 10,500 tonnes of crude oil escaped into the sea from the Hebei Spirit. The recent oil leakage from a tanker in seas off Taean has turned the sea farms and fishing areas on the country's western coast into a sea of oil. Analysts say the spill is considered as one of the world's devastating sea pollution cases involving oil. In our contemporary society where people are exposed to potential dangers in every aspect, no one can be free from such dangers. With an increase in human casualties due to disaster, disaster reporting plays a vital role in preventing and minimizing damages. Despite such enormous significance, however, Korean disaster reporting has not performed effectively. In this contexts, this study analyzed the problems of disaster reporting in Korea, with the case of Hebei Spirit oil Spill in Taean-gun. And, this study suggest the establish ways and means needed to improve the disaster reporting in Korea with the case of Hebei Spirit case.

최근 지구온난화의 영향으로 겨울철 한파를 야기하는 일이 잦아지고 있다. 우리나라에도 그 영향으로 매년 겨울 한파가 지속되고 있다. 그러므로 겨울철 적설량을 기록하고 갑작스러운 재난에 대비하는 것은 지구온난화의 또 다른 숙제가 되었다. 우리나라는 전통적으로 폭설 피해가 크지 않았기 때문에 적설관측소의 수가 강우관측소에 비해 현저히 적다. 그리하여 추가적인 적설관측소의 설치가 필요하다고 판단되지만, 이에 앞서 우리나라의 현재 적설관측소의 분포현황을 분석하였다. 1월, 2월, 12월의 최대 최심신적설량과 관측소 고도자료를 K-평균 알고리즘의 4개의 변수로 사용하였으며, 전국에서 총 94개의 적설관측소를 자료보유기간으로 분류하여 군집분석을 수행하였다. 군집분석 결과 서해안지역, 태백 소백산맥을 따라 존재하는 내륙산악지역, 경상도와 남해안 그리고 제주도지역, 울릉도와 대관령으로 군집이 형성되었다. 또한, 제주도의 적설관측소가 해안가 위주로 설치되어있어, 비교적 눈이 많이 오는 한라산 산간지역에 추가적인 적설관측소 설치가 고려되어야 할 것이다.

This research proposes strategies about providing detour route information and traffic management for flood disasters. Suggested strategies are based on prevention and preparation concepts including prediction, optimization, and simulation in order to minimize damage. Specifically, this study shows the possibility that average travel speed is increased by proper signal progression during downpours or heavy snowfalls. In addition, in order to protect the drivers and vehicles from dangerous situations, this study proposes a route guidance strategy based on variational inequalities such as flooding. However, other roads can have traffic congestion by the suggested strategies. Thus, this study also shows the possibility to solve traffic congestion of other roads in networks with emergency signal modes.

Purpose: The purpose of this study is to examine the directions for establishing a disaster safety village in rural areas where damage from a similar type of disaster occurs repeatedly by conducting the consciousness survey targeting at experts and disaster safety officials in a local government. Method: The risks of disaster in rural areas were examined and the concept and characteristics of disaster safety village which is a measure on the basis of Myeon (township) among the measures of village unit were examined in order to carry out this study. In addition, opinion polling targeting at officials-in-charge in the local government and survey targeting at experts in disaster safety and building village were conducted. Based on the findings, the directions for establishing a disaster safety village that fitted the characteristics of rural areas were examined. Result: The officials-in-charge in the local government answered that rural areas have a high risk of storm and flood such as heavy snowing, typhoon, drought, and heavy rain as well as forest fire, and it is difficult to draw voluntary participation of farmers for disaster management activities due to their main duties. They also replied that active support and participation of residents in rural areas are necessary for future improvement measures. The experts mostly replied that the problem of disaster safety village project is a temporary project which has low sustainability, and the lack of connections between the central government, local governments and residents was stressed out as the difficulties. They said that measures to secure the budget and the directions of project promotion system should be promoted by the central government, local governments and residents together. Conclusion: The results of this study are as follows. First, a disaster safety village should be established in consideration of the disaster types and characteristics. Second, measures to secure the budget for utilizing the central government fund as well as local government fund and village development fund should be prepared when establishing and operating a disaster safety village in rural areas. Third, measures to utilize a disaster safety village in rural areas for a long period of time such as the re-authorization system should be prepared in order to continuously operate and manage such villages after its establishment. Fourth, detailed measures that allow residents of rural areas to positively participate in the activities for establishing a disaster safety village in rural areas should be prepared.

Heavy snow is a natural disaster that causes serious economic damage. Since snowfall has been increasing recently, there is a need for measures against heavy snowfall. In order to make a policy decision on heavy snowfall, it is necessary to estimate the precise amount of damage by heavy snowfall. The direct damage of the heavy snow is severe, however the indirect damage caused by the road congestion and the urban dysfunction is also serious. Therefore, it is necessary to estimate indirect damage of snowfall. The purpose of this study is to estimate the effects on the regional economy from the limitation in traffic logistics caused by heavy snow using the transport demand model and inoperability input-output Model. The result shows that the amount of production loss caused by the heavy snow is KRW 2,460 billion per year and if the period of snowfall removal is shortened by one day or two days, it could be reduced to KRW 1,219 or 2,787 billion in production loss.
