China is one of the few countries where natural disaster strike frequently and cause heavy damage. In this paper, we mathematically develop two models to assess fuzzy risk of natural disaster in China. One is to assess the risk based on database of historical disaster effects by using information diffusion method relevant in fuzzy information analysis. In another model, we give an overview over advanced method to calculate the risk of release, exposure and consequence assessent, where information distribution technique is used to calculate basic fuzzy relationships showing historical experience of natural disasters, and fuzzy approximate inference is employed to study loss risk based on these basic relationships. We also present an examples to show how to use the first model. Result show that the model is effective for natural disaster risk assessment.

In this paper, we conducted a study on ways to not only check disaster information on smart-phone in the event of a disaster, but also simultaneously check it on wearable devices using short-range wireless communication. Wearable devices commonly used include such devices as wireless earphones, smart bands and smart-watches. Among these devices are smart-watches that allow users to view disaster information in the event of a disaster. However, because current disaster message can only check on smart-phones, research was conducted on how to deliver disaster information received from smart-phones to smart-watches. If studies such as this paper continue, we will be able to recognize disasters more efficiently in the event of a disaster and to carry out preparations for them.

In this paper, we identified the national alert service and recognized the problem that disaster message is received only from smart phones, which are mobile communication devices in the event of a disaster. Thus, we conducted a study on how to use NFC to identify disaster characters in navigation. Research was conducted on how to receive and utilize disaster message and disaster information when using smart phone navigation as well as application development-enabled navigation. If studies such as those in question continue, disaster situations and information will be provided in a more diverse environment and users will all be able to access disaster content to prepare for disasters and prevent or reduce damage.

One of the purposes of Information Technology (IT) is to support human response to natural and social problems such as natural disasters and spread of disease, and to improve the quality of human life. Recent climate change has happened worldwide, natural disasters threaten the quality of life, and human safety is no longer guaranteed. IT must be able to support tasks related to disaster response, and more importantly, it should be used to predict and minimize future damage. In South Korea, the data related to the damage is checked out by each local government and then federal government aggregates it. This data is included in disaster reports that the federal government discloses by disaster case, but it is difficult to obtain raw data of the damage even for research purposes. In order to obtain data, information extraction may be applied to disaster reports. In the field of information extraction, most of the extraction targets are web documents, commercial reports, SNS text, and so on. There is little research on information extraction for government disaster reports. They are mostly text, but the structure of each sentence is very different from that of news articles and commercial reports. The features of the government disaster report should be carefully considered. In this paper, information extraction method for South Korea government reports in the word format is presented. This method is based on patterns and dictionaries and provides some additional ideas for tokenizing the damage representation of the text. The experiment result is F1 score of 80.2 on the test set. This is close to cutting-edge information extraction performance before applying the recent deep learning algorithms.

Due to recent climate change, lager-scale storm and flood disasters have occurred. To prepare for this, the government is operating the national disaster management information system(NDMS), it is insufficient that unification and standardization of disaster site information data. In this study, to establish a disaster information display system, spatial DB was stored, quality standards were presented and the quality of spatial information currently provided was evaluated. As a result of evaluation, spatial information is established as different standard for each institution. So it is difficult to integrate and use. It considered that prepare a common standard to redeem this difference.

Large-scale natural disasters such as typhoon and localized torrential downpour cause widespread human and property damages. Recently, management systems using GIS are being developed to manage such disasters from various angles. Integrated disaster management encompasses diverse areas such as prediction through the computation of disaster information and field support for response. The development of disaster information systems must also consider the installation of various computation modules. Furthermore, GIS is generally included for realistic description of the field situation and for spatial operations. This study aims to develop the core module of a visualization platform for the 3D GIS services of integrated disaster information using Unity engine This system will enable integrated disaster management from various angles, encompassing disaster prevention experts, field support personnel, and citizens.

Large-scale and complex disasters have frequently occurred all over the world recently, and they are repeated every year. Accordingly, the need for the systematic management and utilization of raw-data and processing information in the past has increased. For this purpose, this study proposed a construction strategy for disaster and safety record information resources archives based on automatic acquisition, which can be used as a hub for disaster and safety information. Based on local and foreign case studies, several consideration factors for building the archives are determined. Finally, this study proposed four steps for constructing the archives. These are as follows: 1) complete enumeration survey of the disaster and safety record information resources, 2) automatic acquisition possibility study, 3) selection of the resources for preservation, and 4) automatic acquisition of metadata. The construction of the archives proposed in this study will facilitate integrated management, sharing, and use of scattered information resources on disaster and safety.

Purpose: The risk of disaster from extreme weather events is increasing due to the increase in occurrence and the strength of heavy rains and storms from continued climate change. To reduce these risks, emergency weather information customized for the characteristics of the information users and related circumstances should be provided. Method: A first-stage emergency weather information delivery system has been developed to provide weather information to the disaster-risk area residents and the disaster response personnel. Novel methods to apply artificial intelligence to identify emergencies have been studied. The relationship between special weather reports from meteorological administration and disaster-related news articles has been analyzed to identify the significance of a pilot study using text analytic artificial intelligence. Result: The basis to identify the significance of the relations between disaster-related articles and special weather reports has been established and the possibility of the development of a real-world applicable system based on a broader analysis of data has been suggested. Conclusion: Through direct alert delivery of weather emergency alerts, a weather emergency alert system is expected to reduce the risk of damage from extreme weather situations.

In the event of a disaster, we need people who specialize in rapid regional disaster recovery. However, in the present disaster response system, disaster relief is carried out at the level of public support, volunteer service, etc. There are various problems such as initial response due to lack of expertise, delays in disaster recovery, and inadequate response to disasters. Therefore, it is necessary to establish a unit with early ability to respond to local governments in the event of a disaster and expertise to enable rapid disaster recovery. Therefore, this study limited the preparation of the reserve forces emergency response units for the direction of local security, disaster relief and disaster relief through emergency disaster recovery under the disaster situation.
