전력사용량이 산업발전과 더불어 기하급수적으로 증가하고 있으며, 한정된 공간내에서 대용량의 전력설비를 설치하기 위해 폐쇄형 배전반이 운영되고 있다. 한국전기안전공사에서 발표한 통계자료에 의하면, 고압이상 전기설비 검사결과 절연내력이 불합격인 경우가 다수 발생하고 있으며, 이는 아크 플래시 사고의 원인이다. 특히 수배전반의 경우 부하설비 또는 외부의 영향을 확인할 수 있는 장치 및 보호설비가 설치되어 있으나 자체 안전장치가 마련되어 있지 않아 자체사고를 신속히 검출하고 판단할 수 있는 기술이 필요하다. 본 논문에서는 해상도가 낮은 저가의 열화상 센서에 고속 DSP를 사용하여 영상처리 기법인 이차원 보간 법으로 해상도를 올려서 사용하는 기술을 이용하여 아크에 의해 발생되는 열특성을 검출하고 검출된 데이터를 전송하여 전기화재사고를 미연에 방지할 수 있는 장치 개발을 위한 기초 특성조사를 실시하였다.

The purpose of this study is to survey the learner's recognition about the descending life lines for the fire emergency escaping purpose (DLL-FEEP). For that, we surveyed 307 adult males and females in Chungcheongnam-do, Daejeon metropolitan city, and Sejong metropolitan autonomous city. The surveyed data was statistically analyzed by SPSS 20.0 win program. In the results, 72.64% research participates have received a fire safety education. However, among them, 39.46% research participates have received a fire safety education without the contents of the DLL-FEEP. The style of the education for the DLL-FEEP is mainly the instructor-led training which is 79.26%. The 81.43% research participates have never used a DLL-FEEP. Based on the results in this study, the political proposal based on these results was as follows. We think that the expansion of the educational contents for the DLL-FEEP need in the fire safety education. We believe that results of this paper will help to serve as a basis for the efficient fire safety education with adults.

The development of industry and the increase in the use of fossil fuels have accelerated the process of global warming and climate change, resulting in more frequent and intense natural disasters than ever before. Since electricity facilities are often installed outdoors, they are heavily influenced by natural disasters and the number of related accidents is increasing. In this paper, we analyzed the statistical status of domestic electrical fires, electric shock accidents, and electrical equipment accidents and hence analyzed the risk associated with climate change. Through the analysis of the electrical accidental data in connection with the various regional (metropolitan) climatic conditions (temperature, humidity), the risk rating and charts for each region and each equipment were produced. Based on this analysis, a basic electric risk prediction model is presented and a method of displaying an electric hazard prediction map for each region and each type of electric facilities through a website or smart phone app was developed using the proposed analysis data. In addition, efforts should be made to increase the durability of the electrical equipment and improve the resistance standards to prevent future disasters.

This study was conducted to investigate whether ego - resilience plays a mediating role in the relationship between adult attachment and job stress of fire officers, and to derive implications for job stress reduction of fire officers. A questionnaire survey was conducted for 480 fire officers working in Seoul and Gyeonggi - do, and correlation analysis and regression analysis were conducted using SPSS 21.0. The results showed that there was a negative correlation between instability attachment and job stress in adult attachment, negative correlation between instability attachment and ego - resilience in adult attachment, and negative correlation between ego - resilience and job stress. Adult attachment and ego - The results showed that there was a statistically significant effect on stress. Ego - resilience was found to full mediate the effect of anxiety of adult attachment on job stress and to partial mediate the effect of avoidance on job stress. This study suggests the need to develop a program that can improve ego - resilience considering the importance of ego - resilience and the occupational characteristics of fire officer. This means that the psychological and psychological factors of the individual should also be considered in order to reduce the level of job stress of the fire service personnel.

This study analyzed the structural and electrical characteristics of an iron fittings type Corrugated Stainless Steel Tubing (CSST) damaged by the Primary Current Injection Test System (PCITS). CSST consists of cladding, tube, nuts, clamp ring, flare cap, socket, and ball valve. For an evaluation of the dielectric withstand voltage, the area between the live part and non-live part of the CCST shall withstand a voltage of 220 V AC for one minute. For an evaluation of the insulation performance by 500 V DC, it is required that the insulation exceed more than $1M{\Omega}$ before the temperature rise test, $0.3M{\Omega}$ after the test. Although the average resistance of the product was $11.5m{\Omega}$, that of the product damaged at a current of 130 A by the PCITS was $11.50m{\Omega}$. Furthermore, parts of the cladding were melted and black smoke appeared when a current of 130 A applied for 10 s. After 60 s, most parts were heated and turned red. At 120 s, the parts that turned red had widened. Although it did not form a normal distribution because the P value was 0.019 with a confidential interval of 95%, it revealed outstanding characteristics with an AD (Anderson-Darling) value of 0.896 and a standard deviation of 0.5573.

In Korea, the Emergency Medical Service, EMS is provided by Fire Services with 119 EMS and all the public uses the service for free. Although it appears very successful and is respected nationally, structural problem EMS exist and are worsening. First of all, the "free riding effect" becomes increasingly problematic. Some argue that 30% of the demands is not urgent or emergent. The total number of demands is increasing even without the free riding effect. The Current EMS system itself cannot meet the increasing EMS demand. The medical aspect is so poor that the EMS cannot dispatch a medical specialist to the scene. The cardiac arrest resuscitation rate is only $1.24{\sim}9.9%$, compared to 40% in Boston, MA, USA. But due to the regulations and limitations of the Fire Service organization, it is difficult to secure enough EMS resources. To work out these problems, it needs a structural innovation. To secure enough resources and achieve higher medical performance we should invite the medical sector and the private sector into EMS arena by contracting partnerships with Fire Services and charging a reasonable EMS fee. We found through statistical test that any partnership system is more effective than fire-alone system and most countries around the world have partnership system rather than fire-alone system.
