The purpose of this study was to identify mediating effect of major satisfaction in the effect of critical thinking disposition on disaster recognition. For this study, 237 students of nursing students from universities in Jeollanam do participated in the study. The data collection was collected on Dec 1 to 7, 2017. The descriptive statistics was used to analyze general characteristics of participants, the differences in disaster recognition according to general characteristics were analyzed by t-test or ANOVA. Regression analysis was conducted to confirm the effect of critical thinking disposition on disaster recognition and Baron, R.M. And Kenny, D.A.'s mediation effect statistic analysis was used to confirm the mediating effect of major satisfaction in critical thinking disposition on disaster recognition. As a result, the critical thinking disposition affects the disaster recognition, and it was judged that the major satisfaction was mediating role. intellectual fairness sub-factor showed perfect mediating effect and confidence and general truth sub-factor showed partial mediating effect. Based on the above findings, it can be seen that not only critical thinking but also satisfaction with the major should be considered in order to increase the recognition of the sudden disaster. In this case, research for linking critical thinking disposition and major satisfaction is likely to be meaningful. Through the results of this study, we suggest the program development of a linkage between critical thinking disposition and major satisfaction to increase the recognition of disaster.

To solve the problems existing in the process of Weibo disaster rumor recognition, such as lack of corpus, poor text standardization, difficult to learn semantic information, and simple semantic features of disaster rumor text, this paper takes Sina Weibo as the data source, constructs a dataset for Weibo disaster rumor recognition, and proposes a deep learning model BERT_AT_Stacked LSTM for Weibo disaster rumor recognition. First, add adversarial disturbance to the embedding vector of each word to generate adversarial samples to enhance the features of rumor text, and carry out adversarial training to solve the problem that the text features of disaster rumors are relatively single. Second, the BERT part obtains the word-level semantic information of each Weibo text and generates a hidden vector containing sentence-level feature information. Finally, the hidden complex semantic information of poorly-regulated Weibo texts is learned using a Stacked Long Short-Term Memory (Stacked LSTM) structure. The experimental results show that, compared with other comparative models, the model in this paper has more advantages in recognizing disaster rumors on Weibo, with an F1_Socre of 97.48%, and has been tested on an open general domain dataset, with an F1_Score of 94.59%, indicating that the model has better generalization.

Purpose: The study examined disaster recognition, disaster preparedness, and the willingness to participate in disaster response among healthcare students. It also identified the factors that can improve healthcare students' willingness to participate in disaster response. Methods: A structured questionnaire was designed, and data were collected from 171 students, who agreed to participate in the study at C-province between December 14, 2022, and December 28, 2022. Results: The scores of disaster preparedness and the willingness to participate in disaster response were 3.22 and 3.53, respectively. The willingness to participate in disaster response was high among those who had experienced a disaster and had disaster-related education. Furthermore, the willingness to participate in disaster response was significantly and positively correlated with disaster preparedness (r = 1.357, p<.001). Conclusion: It is important to mandate the provision of disaster preparedness education to increase the level and quality of disaster preparedness and the willingness to participate in disaster response.

The purpose of this study was to analyze the structural relationship between radiation hazards and radiation benefits effecting on overcoming recognition of Fukushima nuclear disaster (FND) in Japan by using structural equation modeling (SEM). The subjects were 248 undergraduates from one university in Chungbuk province in Korea. From June 1, 2017 to July 30, 2017, we conducted a questionnaire survey on the radiation hazards and radiation benefits and on the overcoming recognition of FND. As a result, it showed that the recognition of radiation hazards has a significant effect on the benefits of radiation, but does not directly affect the overcoming recognition of FND. However, the recognition of radiation benefits has been mediating between radiation hazards perception and the overcoming recognition of FND. Therefore, it can be empirically confirmed that despite the radiation hazards the recognition of overcoming the FND depends on the level of radiation benefits by using the SEM.

The administration of Korean local governments in charge of natural disaster management and manmade disaster management has been completely or partially integrated to the fire fighting headquarters since 1990's. Therefore the relationship between the fire fighters and the regular officers has been more important. So in this study, I made a questionnaire about management ability, rescue activities, disaster, business efficiency of the disaster management organization. And then I did a question research to the comparison analysis of recognition between fire fighter and regular officers of Seoul disaster management organization. As a result of the comparative analysis of understanding, there is a meaningful difference among facilities of management ability, man-made disaster of disaster, business cooperation and business connection of business efficiency. Through the comparison analysis of recognition, I tried to present the improvement of Seoul disaster management organization.

Recently, Domestic situation have been occurred lots of accidents related with disaster and safety including Sewolho Accident. Nevertheless there is insufficient about IoT recognition service technics. Furthermore mosf of people aware of M2M and IoT technics, but there is no service system at a whole perspective. Goverment have been discuss about that disaster and saftey but it is hard to construct that service system. In this paper, we suggest a process and technology about IoT recognition service on disaster and safety.

A special purpose machine with two manipulators and quadruped crawler system is being developed to work at disaster sites where it is intended to quickly respond in the initial stages after the event. In this study, a terrain recognition module is developed so that the above special purpose machine can quickly obtain ground information to help choose its path while recognizing objects in its way, this is intended to enhance the remote driver's limited situational awareness. Terrain recognition modules were developed for two tasks (real-time path guidance, precision terrain measurements). The real-time path guidance analyzes terrain and obstacles while moving, while the precision terrain measurement feature provides more accurate terrain information by precisely measuring the ground in front of the vehicle while stationary. In this study, an air-cooled sensor protection module was developed so that the terrain recognition module can continue its vital tasks in the event of exposure to foreign substances, including scattered dust, mist and rainfall, as well as high temperatures.

Since the mankind started its space mission, the number of artificial space objects has been increasing exponentially. It contains not just the space machines which are in use but the machines which are out of order. Meantime, those dead machines are being a serious danger, a real threat to human's lives and property because of it could re-enter into the earth's atmosphere and fall to the ground causing mega-disaster. As the number of space activities gets growing so far, the re-entry of the space objects will be a lot more happened in the future. Therefore, not just natural space object like asteroids but the artificial space object like artificial satellite and space station can cause the disaster by falling to the ground. To protect our nation and our property, the government has set up the space disaster management center in Korea astronomy and Space science Institute. In this study, we surveyed public's recognition of the space object's re-entry situation and analyzed it to contribute building national space disaster management policy.

People generally believe that disaster forecast and warning systems and response systems are well established in the age of cutting edge technology. As a matter of fact, reliable systems to respond to disasters are not properly equipped, as we witnessed the Sewol ferry disaster in 2014. The existing forecast and warning systems are based on sensor information with low efficiency, and image information is only operated by monitoring staff manually. In addition, the interconnection between a warning system and a response system in order to decide how to cope with the recognized disaster is very insufficient. This paper introduces the CCTV based disaster recognition and real time crisis response system composed of the CCTV image recognition engine and the crisis response technique. This system has brought the possibility to overcome the limitations of existing sensor based forecast and warning systems, and to resolve the problems in the absence of monitoring staff when responding to crisis.
