The purpose of this study is to develop and validate the disaster safety awareness scale for high school students. For this purpose, the previously developed disaster safety awareness scale and related prior research was analyzed. Questionnaire data was collected from March 22 to May 25, 2021 from 1054 students (male: 569, female: 485) in the first, second, and third grades of 5 high schools in 3 cities. Through the process of revising, supplementing, and reviewing the items extracted through preliminary research and preliminary test together with experts and students, a final disaster safety awareness scale consisting of 24 items was developed. This scale consists of four sub-factors: 'disaster prevention', 'disaster response A', 'disaster response B', and 'disaster recovery'. Good reliability and validity were secured through exploratory and confirmatory analyses. The significance of this study is that it laid a basic and objective foundation for high school students' disaster safety awareness research by developing a validated scale in a situation where the development of disaster safety awareness scales for high school students was still insufficient. It can be used as useful data for fire safety education as well as a psychological measurement tool for fostering fire safety awareness.

신호처리원과 그 방식은 네트웍 구성시 매우 중요하다. 따라서 대단위단지에서 많이 적용되고 있는 자동화재탐지설비의 화재수신기 네트웍과 통신네트웍에 접속시와 수신기에서 발생하는 통신 데이터를 일반 통신네트윅에 접속하여 발생하는 데이터전송시 문제점에 대하여 고찰한 것이다. 경보설비의 구성에서 중계기와 수신기간의 통신 형태를 측정하여 보편화된 통신방식을 사용하였다는 것을 알 수 있었으며 수신기에서 통신네트윅간의 연결은 수신기의 Ethernet 통신모듈을 통한 프로토콜 형태를 확인하였다.

On this study, we extracted pending problem and controversial point from management of disaster such as terror for domestic massive performance and then, investigated countermeasure plan against disaster for massive performance through comparison and analysis between anti-disaster strategy of Korea and U.S. U.S are conducting security system actively for passenger of major facilities such as public institution. Nonetheless, In U.S that has the world's best security system, serious affair such as 911 terror and Boston marathon terror are continued to happen. When considering domestic situation that North Korea and South Korea are antagonistic to each other, it is judged when it is high time to prepare for threat of terrorism. Accordingly, On this study, through analyzing of latest terror attacks in U.S and disaster risk in the nation, we analyzed in detail countermeasure plan classified as legislation, operation of security system, instilling a sense. As the result of this analyzing, using by flow-chart, we suggested domestic optimized disaster management system for massive performance. Consequently, we propose to establish systematized disaster management system such as preliminary survey of disaster influence for massive performance.

Disaster prevention resources consist of persons, equipments, goods, and facilities. Specially, equipments and goods are internally managed in the regional office, and may be leased to the inter-offices. National Disaster Management System(NDMS) managed the resources in the separated system. That is, one system is managed by regional disaster prevention system, the other is managed by the central disaster prevention system which receives the data from the regional disaster prevention system. Because the regional disaster prevention system updates the resource information quarterly, it is difficult to confirm the exact information. In this study, we propose the model which makes to supply in timely the resource to the disaster using the managed resource with RFID technology. Firstly, we classified the resources based on the resource types for the easily search. After then, we defined ID and attributes information of the resources. From the information, we described the management model for the real time resource.

In the case of a disaster, the damage caused by the disability vulnerability of persons with disabilities is significantly increased, discussing about a problem for the protection of the vulnerable class. However, until now policy, technology and response guidelines for disaster and safety have been focused on the general public. Therefore, it is necessary to develop customized support technology for disaster and safety considering vulnerable characteristics of vulnerable class. Firstly, it is necessary to prepare draft improvement proposal of act and support system related disaster and safety for persons with disabilities and older persons. So, this study was carried out analysis of act, policy and support system on disaster and safety for persons with disabilities and older persons of domestic and overseas in order to draw implication. Furthermore, we established direction for improvement of act and policy on disaster and safety for persons with disabilities based on the analysis, and suggested draft improvement proposal.

This is a basic research on potential application of fire detection by measuring fire detection tendency of indoor air quality measurement factors. In this study, operation experiment using smoke detector sensitivity tester and paper fire experiment specified in UL 268 standards were conducted to evaluate the fire detection tendency of indoor air quality measurement factors. Based on the cross-substitution of values measured in the paper fire experiment, PM10 (excluding average) and HCHO (excluding average and maximum) for the indoor air quality meter (IAQ); PM1.0, PM2.5, and PM10 for IAQ S2; and CO (excluding the average and maximum) for combustion gas analyzers showed consistent tendency despite changes in the measured values for smoke generation under all experimental conditions. In particular, PM10 and CO are considered the most applicable fire detection factors among the factors measured in the experiment.

This study evaluates the radiation protection effects of Schizonepeta tenuifolia water extract on white rat by gender. Schizonepeta tenuifolia contains polyphenol and flavonoid, which are typical substances that remove free radical. Thus, to determine the effectiveness of radiation protection, the Schizonepeta tenuifolia water extract was administered to Sparaqu-Dawely (SD) rat males and females for two weeks, followed by hematological analysis, analysis of changes in the length of the small intestine villi length, and SOD activity evaluation. The male rat in ST+IR group showed a slightly greater recovery of platelets than the IR group. The ST+IR group also showed a higher platelet recovery capability than the IR group. lymphocyte showed that male and female rat ST+IR groups have higher resilience than IR groups likewise platelet. After irradiation, the villi length of the male rat and female rat decreased less in ST+IR group than in the IR group, indicating that the villi length of all genders was less damaged. This result confirmed that the Schizonepeta tenuifolia water extract had a radiation protection effect.
