  • 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.

  • This study suggests a plan to expand the rural experience program linked to natural disaster through the case analysis of the village of Garisan-ri, Inje-gun, Gangwon-do, Republic of Korea. This will help to establish the necessary improving and policies for Re-leap of rural villages in disaster areas and activation of rural experience villages. The local residents have created flood recovery stories, disaster response content, and disaster prevention camp sites, all of which have been hit by serious disaster damage. It has also contributed to the revitalization of the village by providing various experience programs such as disaster response training, crossing rapids, and evacuation experience. This is a way to get rid of the negative perception of disaster and utilize it. The conversion of idea through disaster experience content contributed to the activation of the area. By linking the disaster experience contents to the rural experience program in the future, it can be helpful to avoid the duplication of contents and limit the similar operation method, which is an existing problem of rural experience villages.

  • In the background of rapid urbanization and frequent earthquakes, earthquake disaster prevention planning has become an important topic of current research. Universities are irreplaceable disaster shelter, as they are public institutions with a lot of open space. This article puts forward the concept of "disaster prevention campus". With the refuge behavioral and psychological characteristics of people in the campus when the earthquake happens, it integrated uses GIS spatial analysis technique, takes Shandong Agricultural University as an example, and studies the spatial pattern of earthquake disaster prevention planning in campus from five aspects. The aspects include building distribution, population distribution, analysis of service radius, infrastructure configuration and choice of the optimal refuge path. On the basis of researches above, reform proposals and specific strategies are put forward to build the safe and harmonious disaster prevention campus.

  • This study has purpose on deducting problems of evacuation plan for vulnerable populations in disaster and suggesting improvement plan through analysis of disaster weakness in domestic rural region aiming at vulnerable populations in disaster like old people containing most of domestic rural population, sometimes being in blind spot of safety when landslide or disaster occur. As a result, we could know that rural regions have high proportion of vulnerable populations in disaster like old people, also being so weak to landslide and slope collapse. So we suggested development of manual describing prevention of disaster and evacuation for vulnerable populations in disaster like old people and disaster evacuation organization for house and minimizing solution for damage of human life through improvement of steep slope evaluation criteria.

  • Recently the use of smart phones and mobile devices is increasing rapidly, data search and retrieval in the mobile environments are generalized. There are only few mobile applications available in the area of agriculture while huge amount of new applications are developed and uploaded. The purpose of this study was to develop the android based mobile application for providing agricultural infrastructure and disaster information. The mobile application was designed through the database establishment and management system, server management system, and mobile application development. The database is composed of weather data, agricultural infrastructure data, and agricultural disaster data. By developing the mobile application which provides agricultural infrastructure information, it is expected to improve the accessibility to agricultural information and mitigate the agricultural disaster damages.

  • Nonpoint sources of pollution (NPS) is defined as diffuse discharges of pollutants (e.g., nutrient, pesticide, sediment, and enteric microorganism) throughout the natural environment and they are associated with a variety of farming practices. Previous studies found that water soluble anionic polyacrylamide (PAM) is one of the highly effective measures for enhancing infiltration, reducing runoff, preventing erosion, controlling nonpoint source of pollutants, and eventually protecting soil and water environment. Potential benefits of PAM treatment in agricultural soil and water environments have been revealed by many research and they include low cost, easy and quick application, and suitability for use with other Best Management Practices (BMPs) for NPS control. This study reviews the various applications of PAM and discusses its further potentials in agricultural environment.

  • Recently the life damage is increasing due to the house disruption and burying accident by the landslide, and most of the damages are concentrating on the agricultural area. This study is a basic study for developing the personal disaster evacuation apparatus that can be installed in the house for the people in agricultural area vulnerable to the disaster in case of the landslide. This study carried out the numerical analysis and the object load test on the personal disaster evacuation apparatus. As a result of this study, it was judged the life damage could be minimized if the personal disaster evacuation apparatus using the glass fiber reinforced plastic (GFRP) materials was installed in the steep slope-land with a high possibility of the disruption.

  • This study intends to conduct a thorough research and analysis on the designated temporary residential facilities for the disaster victims in order to bridge the gap between the temporary residential facilities for the disaster victims in country and city, and understand the current status of the designated temporary residential facilities for the disaster victims in rural and urban areas. As a result, the designated temporary residential facilities for the disaster victims in urban areas are bigger and have higher capacity, implying the necessity to designate facilities in rural areas that can accommodate larger number of people. As to the analysis of the representative temporary residential facilities for the disaster victims in rural areas, different regions had different types of designated facilities and the number of facilities also showed big difference depending on regions. So it is believed that local governments should improve the process and system of designating temporary residential facilities for the disaster victims.
