Multiple people using places are being managed to prevent disasters by the special law for safety supervising of multiple people using spots. The KESCO is managing the places through intensification of inspection. Perfect safety is not insured by frequencyinspections because disaster symptoms in electrical facilities include invisible faults. Especially, entertainment spots, such as entertainment bars and karaoke bars, are different from other multiple people using places, and active reaction to prevent electrical fires is impossible. Therefore, special protection plans to prevent electrical disasters are needed. In this paper, equipments of entertainment spots were researched, and their electrical characteristics were analyzed. The function for detecting aloose terminal, which is one of the main causes of electrical fires, was developed.

Heavy snowfall was occurred over the south-western part of the Korean Peninsula called as Honam Districts, on two days from 21 December 2005. The development mechanism of snowfall and its characteristics were analysed using observation and numerical data provided by Korea Meteorological Administration. In comparison with other years Arctic air mass developed and maintained during all December 2005 due to active planetary waves with three branches. And jet streams at lower and higher levels make easy development of snow convection cells. Especially thermal low induced by mesoscale heat and dynamic sources, also help the developments of convection cells in strong ascension. The understanding the relation between synoptic and mesoscale circumstance, therefore, is also important to predict the heavy snowfall and to prevent the disaster.

Construction victims have increased year by year. Disaster proportion is also increasing continuously. Looking over the causes of disasters by each type of work, fall from working platform indicate the highest rate above all so that it is urgently required to set up safety measures. This study is to grasp the present status of construction accidents, to identify areal characteristics of the top 20% accidents on the basis of working platforms with the highest accident rate, to grasp the causes of accidents after their analyses, and to present methods to reduce casualties related to working platforms. As measures to reduce construction disasters, this study proposes to improve safety management and training on working platforms, to complement safety regulations, and to better performance including the development and expansion of certified products suitable for safety regulations.

Although installations and usages of gang-form that has advantages of preventing fall disaster, the serious disasters from gang-form occur every year. This research focused on the continuous prevention of disasters in construction of outer wall of apartment working site through step by step safety management worker's checking table. The result is the worker's checking table for safety management in apartment gang-form works, through safety guidelines case studies, interviews with safety management experts and then extracting a check list.

현재 상용화 중인 4세대 이동통신의 사용자가 급증하고 있다. 현재 4세대 이동통신 국내 가입자는 천만 명이 넘어섰으며, 4세대 이동통신에 어느 기술이 사용이 되고 데이터 전송속도가 얼마나 빠른지 알고 사용하는 사람은 많지 않다. 따라서 본 논문에서는 4세대 이동통신에 사용되고 있는 3GPP계열의 LTE-Advanced와 와이맥스 계열의 IEEE802.16m의 데이터 전송속도 기반의 이론적인 속도값과 현재 상용화된 4세대 이동통신의 데이터 전송속도의 실제 측정값을 비교, 분석하여 상호간의 특징적 차이를 분석하는 연구를 수행하였다.

현대 사회에서 대부분의 사람들이 SNS 어플리케이션을 선호하고 자주 이용하고 있다. 그 동안 삐삐, 휴대폰, 문자, 싸이월드&메신저 등 커뮤니케이션의 도구가 진화해왔으나 점차적으로 단순화를 추구하는 경향이 증가하고 있다. 또한, 인터넷을 이용한 인간관계가 대중화되면서 삶을 살아가는데 있어 SNS(Social Networking Service)는 매우 중요한 요소가 되고 있다. 따라서 본 논문에서는 현대 사회에서 SNS에 열광하는 이유와 SNS의 사용목적, 선호도 등을 설문 방식의 적용으로 조사, 분석하는 연구를 수행하였다.

서울에는 지상 60층이 넘는 초고층 건물과 지하 8층 이상의 초심층 건축물. 지하철과 상가, 백화점, 호텔, 전시장등이 연결된 대규모 복합유통시설 지역 등이 있다. 이런 지역이나 시설에서 화재와 같은 재난사고가 발생시 진압작전을 위해 투입된 소방관의 위치를 제대로 파악할 수 없으면 투입된 소방관의 안전은 물론 효율적인 지휘통제가 제한되어 결국 더 많은 자체 피해와 더불어 화재 진압 및 시민 구조에 제한을 받을 수밖에 없다. 이러한 대형재난에 유비쿼터스 기술을 활용하여 투입한 소방력의 효율적인 운영과 과학적인 진압작전을 구사하여 시민의 생명과 재산을 최대한 보호할 수 있는 재난대응지원 시스템 구축방안을 제시하였다.

This study has analyzed applicable characteristics on big data of the meteorology and climate depending on press releases in the media. As a result, more than half of them were conducted by governmental departments and institutions (26.9%) and meteorological administration (25.0%). Most articles were written by journalists, especially the highest portion stems from straight articles focusing on delivering simple information. For each field, the number of cases had listed in order of rank to be exposed to the media; information service, business management, farming, livestock, and fishing industries, and disaster management, but others did rank far behind; insurance, construction, hydrology and energy. Application of big data about meteorology and climate differed depending on the seasonal change, it was directly related to temperature information during spring, to weather phenomenon such as monsoon and heat wave during summer, to meteorology and climate information during fall, and to weather phenomenon such as cold wave and heavy snow during winter.

For the period between 1991 and 2009, the annual average of 448 forest fires occurred in Korea. Above all, approximately 94% of the total fires frequently occurred during the spring and fall seasons. Therefore, we need to minimize the damage of forest fire and manage them systematically. In this study, we analyzed the spatio-temporal distribution patterns for the frequency of forest fire occurrences by each city and gun during dry season between 1990s and 2000s using GIS. Then we compared to analyze the frequency of forest fire occurrence by ten-day intervals in 2000s with that in 1990s. As a result of analysis, early April showed the highest frequency of forest fire occurrence in both 1990s and 2000s. Compared to the 1990s and 2000s, the regional change of forest fire showed the most frequent fire events around Chungcheong province. Especially extra 27 fires increased in Daejeon city, and the second most frequent fire had more than 10 fires in Jeolla province and Incheon. However, the number of fire frequency decreased by 12 fires at the end of April in Hongcheon-gun(the province of Gangwon). This is the largest drop over the study period. We consider that this paper will utilize usefully to establish regional counterplan for forest fire prevention by understanding regional forest fire patterns from seasonal change.

Purpose: Due to the change of demography, the ratio of senior drivers has increased and the transition to a super-aged society is expected to make more seniors drive in the future. Method: In this research, we analyzed medical characteristics of the driver's age-specific decline in body function and saw that both the function of the physical as well as mental capacities deteriorates as people age. Among them, various functions are precipitously weakened after reaching 70, implying that those over the age of 70 are classified as seniors in a medical sense. In this context, we also could identify that based on such age criteria, various safety policies for senior drivers should be developed and set up in Korea. Result: We could find a steep fall in the physical function of body after reaching 70 from the chronological change of cognitive function and judgment ability. In particular, it is revealed that the driving license institution and aptitude test for drivers over 70 should be thoroughly examined, as physical functions necessary for driving such as eyesight and hearing ability is not strong enough in many drivers over 70. Conclusion: Focusing on the physical capacity to drive, we tried to find the hazardous age bracket of senior drivers which might influence driving behaviors. Going forward, we expect this work would help to understand the policies for senior drivers and drivers' physical differences.
