  • In order to reduce the amount of damage from natural disasters, we needs prevention meteorological database classified into the cause of disaster, damage elements etc. For this, we have analyzed four data, such as Statistical yearbook of calamities issued by the National Emergency Management Agency and Annual Climatological Report issued by the Korea Meteorological Administration and Recently 10 years for natural disaster damage and Statistics Yearbook from the Ministry of Government Administration and Human affairs. Through the analysis of disaster data, we have selected input variables, such as causes and elements, occurrence frequencies, vulnerable areas of natural disaster, etc. In order to reduce damage from natural disaster, the prevention activities and forecasting based on meteorological parameters and damage datas are required. In addition, it is necessary to process meteorological information for disaster prevention activities. Through these procedure, we have established the foundation of database about natural disasters. This database will be used to assess the natural disasters and build risk model and natural disasters mitigation plan.

  • In order for effective disaster prevention, it is necessary to have some idea of when, where, why and what kind of weather disasters may occur, and how large they may be. But the regional characteristics of Shizuoka Prefecture from the viewpoint of weather disasters have not been studied before. In this study, the authors gathered the data which represent how many times weather disasters occurred in Shizuoka Prefecture in the last fourteen years, and then divided it into some regions using a multivariate analysis. The authors adopted principal component analysis on this data, and then adopted cluster analysis with principal component scores which must be significant in the previous analysis. Finally the authors set the regional division based on these clusters and described the regional characteristics. This study could contribute to the weather disaster prevention in Shizuoka Prefecture.

  • The railroad system must ensure not only the safety of facilities but also the prevention of natural and environmental disasters. The infrastructure must be strengthened in order to prevent rail damage by natural disasters and other causes. Thus, it would be able to prevent damage due to such natural factors like heavy rain and snow fall, wind, and catastrophic earthquakes. It seems that it would be the best way to install safety facilities throughout the entire length of a route, but one would not be able to provide for the costs involved in this approach. Therefore, these facilities must be installed at selected locations that is the most vulnerable to disasters. In this paper we propose the examples of both foreign and domestic methods in order to prevent from damages caused by the above-mentioned natural disasters and others.

  • The high density of population and building; can cause catastrophe in urban areas when natural or artificial disasters break out. The aim of this paper is to assess comprehensive disasters risk of urban areas by Geospatial Information System. For this purpose, we classified disasters risk of urban areas into low categories: flood, fire, building-collapse, and shelter, and then determined factors for hazard risk assessment respectively. The results of hazard assessment can be applied to minimize the demage of disasters in establishing the urban management planning. For more systematic and professional approach the further research is need to consider more disaster assessment factors and join with related experts.

  • The number of disasters caused by natural or human-made events such as earthquakes, tsunamis, floods, typhoons, industrial disasters, and the recent outbreak of COVID-19 has increased and the damage caused by such disasters is increasing every year. Disasters can cause physical destruction and also have unexpected psychological impacts, such as post-traumatic stress disorder (PTSD). Ear acupuncture is a treatment modality that can be helpful for both physical and mental health problems. Since ear acupuncture is a cost-effective, flexible, and safe treatment tool, it has the potential to provide medical assistance in disasters. The National Acupuncture Detoxification Association (NADA) auricular acupuncture protocol, originally developed for addiction treatment, has been used for mental illness and behavioral symptoms in both community health settings and in a variety of disaster, terror, and refugee settings. In this review, we introduced the NADA protocol, including its history, features, training, clinical evidence, and cases in disaster settings, suggesting that the NADA protocol could be utilized as a disaster medical support model in Korean medicine.

  • Cultural heritage passing down to posterity is a global concern. But there are many culture heritage that not remained to now disappeared by various disasters. It is told that disaster is learnt from disaster. The most fundamental task in disaster prevention is to collect and analyze cases of accidents so as not to repeat a disaster. In other words, an analysis of various disaster-related materials and their countermeasures in the Joseon period is an actual condition-based phenomenological methodology used to prevent disasters at cultural properties today. In this context, it is important to collect histories of disasters in the Joseon period, to extract disaster-related historical data and to categorize the data to build a disaster literature database. This study has produced [Database of Disasters in the Joseon Era], a collection of articles on fire outbreaks based on The Annals and The Daily Records belonging to the Memory of the World. On the basis of this chronology, human and property damages caused by fires in Joseon have been examined, identified by districts, as well as disaster technologies, have been analyzed. It has also built disaster vulnerability maps in the Joseon Dynasty Era.

  • Multiscattering occurs when a laser transmits into dense atmosphere targets (e.g. fogs, smoke or clouds), which can cause depolarization effects even though the scattering particles are spherical. In addition, multiscattering effects have additional information about microphysical properties of scatterers. Thus, multiscattering can be utilized to study the microphysical properties of the liquid water cloud. In this paper, a Monte Carlo method was used to simulate multi-scattering transmission properties of Lidar signals in the cloud. The results showed the slope of the degree of linear polarization (SLDLP) can be used to invert the extinction coefficient, and then the cloud effective size (CES) and the liquid water content (LWC) may be easily obtained by using the extinction coefficient and saturation of the degree of linear polarization (SADLP). Based on calculation results, a microphysical properties inversion method for a liquid cloud was presented. An innovative multiscattering polarization Lidar (MSPL) system was constructed to measure the LWC and CES of the liquid cloud, and a new method based on the polarization splitting ratio of the Polarization Beam Splitter (PBS) was developed to calibrate the polarization channels of MSPL. By analyzing the typical observation data of MSPL observation in the northern suburbs of Nanjing, China, the LWC and CES of the liquid water cloud were obtained. Comparisons between the results from the MSPL, MODIS and the Microwave radar data showed that, the microphysical properties of liquid cloud could be retrieved by combining our MSPL and the inversion method.

  • With the increase in occurrence frequency and severity of natural disasters due to climate changes arising from global warming, damage in the landscaping field is rising. This leads to legal disputes, and is increasing social and economic damage, too. Especially even though landscape trees which are highly affected by external environments, suffer lots of damage from natural disasters, there is no specific scope of disaster criteria and thus it brings plenty of problems of damage restoration and compensation. Therefore, this study aims to suggest that gives ways to improve related criteria for damage of landscape trees from natural disasters. For this objective, this study analyzed damage cases of landscape trees and precedents, and compared Korean and Japanese legal systems and criteria regarding natural disasters with each other. The analysis result showed that opinions of experts have a great deal of influence on judgment results, since there is no definite legal basis on damage from natural disasters in the landscaping field. This implies the need for a professional and objective appraisal process. According to the comparative analysis of Korean and Japanese legal systems and criteria regarding natural disasters, Korea lacked in laws and criteria on natural disasters of landscape plants in Korea, whereas there were concrete disaster assessment standards of landscape trees in Japan. For improving natural disaster-related systems and criteria in the landscaping field, therefore, this study presented 'Revision of related laws', 'Revision of appraisal and loss assessment criteria', 'Revision of standard specification of landscaping project', 'Compulsory insuring against disasters', 'Reasonable fulfillment of contract', and 'Compulsory cost estimation for disaster restoration', as improvement plans.
