Disaster psychiatry is a new emerging area of psychiatry, in which psychiatrists help to minimize psychological impact of a disaster and to reduce secondary morbidities. In our society, more children and adolescents are facing disasters nowadays. Thus, the necessity for the disaster psychiatry is increasing. After a trauma, children express various symptoms in relevance to their age, development, and their environmental support. The recovery from the disaster and its long-term effect are also influenced by those factors. Psychiatric intervention in a disaster consists mainly of crises intervention and supportive psychotherapy, which includes counseling the victims, educating and providing information to the public, providing support and consultation to the community, and referring of at-risk or severely impaired individuals for more intensive clinical evaluation and care. In addition to a summarized concept of disaster psychiatry, this article presents the adverse psychological effects of children and adolescents exposed to disaster and issues related to the psychiatric intervention.

Recently, large-scale multi-hazards have been occurred in the various areas of the world. A variety of Earth observation sensors such as satellite EO, aerial and terrestrial LiDAR have been utilized for global natural disaster monitoring. Especially, commercial satellites which observe the Earth regularly and repeatedly, and acquire images with cm-level high spatial resolution enable its applications to extend in the fields of disaster management from advanced disaster monitoring to timely recovery. However, due to existing satellite operation systems with some limitations in almost real-time and wide regional disaster response, close international collaborations between satellite operating organizations like NASA, JAXA, KARI etc. have been required for collecting satellite images in time through a satellite platform with multi-sensors or satellite constellation. For responding domestic natural disaster such as heavy snowfall and extreme rainfall in 2011, this paper proposes a disaster management system for timely decision-making; rapid acquisition of satellite imagery, data processing, GIS analysis, and digital mapping through cooperation with NDMI in Korea and International Charter-Space and Major disasters.

Natural disasters are occurring frequently due to typhoon and flood. Especially, damage scales are increasing these days because of climate change. When natural disasters occur, civil engineering officers investigate them for the recovery. If public facilities are damaged, the disaster damage investigation must be finished within 7days. Currently, natural disaster damage investigation is done on two levels, field investigation and data input into NDMS. However, having those two overlapped most of the time, and we must do subsidiary works things to register field investigation data into system. Work efficiency is decreased due to repetition of additional work. So, many civil engineering officers indicated problems such as lack of manpower and time. In this study, We developed work process on natural disaster damage investigation that involves using smart phone to solve problems such as shortage of time and manpower.

Remote sensing which observes repeatedly the whole Earth and GIS-based decision-making technology have been utilized widely in disaster management such as early warning monitoring, damage investigation, emergent rescue and response, rapid recovery etc. In addition, various countermeasures of national level to collect timely satellite imagery in emergency have been considered through the operation of a satellite with onboard multiple sensors as well as the practical joint use of satellite imagery by collaboration with space agencies of the world. In order to respond heavy snowfall disaster occurred on the east coast of the Korean Peninsula in February 2011, snow-covered regions were analyzed and detected in this study through NDSI(Normalized Difference Snow Index) considering reflectance of wavelength for MODIS sensor and change detection algorithm using satellite imagery collected from International Charter. We present the application case of National Disaster Management Institute(NDMI) which supported timely decision-making through GIS spatial analysis with various spatial data and snow cover map.

This study aimed to analyze the authenticity of dark tourism, and to discuss the possibilities and limitations of disaster tourism as an alternative type of tourism in post-modern society. For this purpose, disaster tourism related with the Great East Japan Earthquake was analyzed. After the disaster occurred, the boundaries between guests (tourists) and hosts (residents) dissolved and disaster communities emerged temporarily. This was followed by social contributive tourism, in which both guests and hosts shared their matter of life-and-death experiences, so existential authenticity became the most important motive and experience for tourism. As time passed, however, existential authenticity was reconstructed ideologically in the socioeconomic political context of disaster recovery, and replaced constructive authenticity. After all, the possibilities of disaster tourism as an alternative type of tourism based on the introspection of modernity were restricted. To discuss the underlying ethical issues of the commodification of disaster tourism, further researches should conducted to consider dark tourism as an alternative type of postmodern tourism.

In the disaster of collapse, an immediate response is needed to prevent the damage from worsening, and damage area calculation, response and recovery plan should be established. This requires accurate detection of the damage affected area. This study performed the detection of the damaged area by using UAV which can respond quickly and in real-time to detect the collapse accident. The study area was selected as B-05 housing redevelopment area in Jung-gu, Ulsan, where the demolition of houses and apartments in progress as the redevelopment project began. This area resembles a collapsed state of the building, which clear changes before and after the demolition. UAV images were acquired on May 17 and July 9, 2019, respectively. The changing area was considered as the damaged area before and after the collapse of the building, and the changing area was detected using CVA (Change Vector Analysis) the Representative Change Detection Technique, and SLIC (Simple Linear Iterative Clustering) based superpixel algorithm. In order to accurately perform the detection of the damaged area, the uninterested area (vegetation) was firstly removed using ExG (Excess Green), Among the objects that were detected by change, objects that had been falsely detected by area were finally removed by calculating the minimum area. As a result, the accuracy of the detection of damaged areas was 95.39%. In the future, it is expected to be used for various data such as response and recovery measures for collapse accidents and damage calculation.

This study derives essential information elements that should be shared in the situation board by utilizing the concept of common operating picture (COP). The COP's concept and actual overseas cases were confirmed, and COP information elements that should be considered for disaster situations were redefined. The COP disaster response information elements were derived by analyzing the standard manual for disaster response and daily situation reports issued in Korea. The information elements were divided into four stages (①Report reception and recognition stages, ②Situation propagation and reporting stages, ③Emergency equipment operation stages, ④Recovery and recovery stages), centered on storm and flood damage. Further analysis of the detailed information elements was conducted to derive the information elements that must be shared in the context board. The information is shared along with spatial and geographical characteristics due to the characteristics of the COP, providing complex information to decisionmakers and officials, enabling diverse access to disaster situations. Furthermore, it is expected that disaster response will be more efficient by sharing the information in common.
