Disaster safety education that can respond when a disaster occurs is very important in Korea, where many human resources are generated due to safety insensitivity. Recently, with the development of virtual reality devices and manufacturing technology, the possibility of using a training system incorporating virtual reality technology in the field of safety education is attracting attention. The virtual training system is very effective for training and education because it has an excellent sense of immersion and allows you to experience various disaster situations without time and space limitations. In this study, cases of disaster safety virtual training contents in Korea are collected and investigated, and the current status of domestic disaster safety virtual training contents is identified and analyzed to identify problems and suggest improvement plans.

The 2006 Millennium Ecosystem Assessment (MA) defines ecosystem services (ES) as "the benefits people obtain from ecosystems". Identifying where ES originates, whom it benefits and how it is changing over a period of time is critical in rapidly developing country like Nepal, where the risk of ES loss is high. In the context of various ecosystem services provided by watershed, this study, particularly deals with water yield, Soil loss and Carbon sequestration computation and evaluation in Bagmati Basin of Nepal. As Bagmati Basin incorporates capital city Kathmandu of nepal, land use change is significant over decades and mapping of ES is crucial for sustainable development of Basin in future. In this regard, the objectives of this study are 1) To compute the total and sub-watershed scale water yield of the basin, 2) Computation of soil loss and sediment retention in the basin, and 3) Computation of carbon sequestration in the basin. Integrated Valuation of Environmental Services and Tradeoffs (InVEST), a popular model for ecosystem service assessment based on Budyko hydrological method is used to compute Ecosystem services. The scenario of ES in two periods of time can be referenced for various approaches of prioritization and incorporation of their value into local and regional decision making for management of basin.

High intensity of population distribution in deltaic setting especially in Asia tends to have increased and causes coastal flood risk due to lower elevations and significant subsidence. Maximum or peak discharge of flood always causes numerous deaths and huge economic losses. New technology of spatial satellite image has been applied to analyze flood damage. In this research, the relationship of nightlight intensity associated with flood damages has been determined during 1992-2013 with spatial resolution of 30 arc sec ($0.0083^{\circ}$) which is nearly one kilometer at the equator in whole six countries along the Mekong River (i.e., China, Myanmar, Lao PDR, Thailand, Cambodia and Vietnam). ArcGIS Hydrological Flow Length Tool has been used to determine the distance of each pixel areas from the rivers and streams. Statistical analysis results highlight the significant correlation R = 0.47 between nightlight digital number and economic damages per unit area (US$/km2) and R = 0.62 for number of affected people for unit area ($people/km^2$). The areas near by the Mekong River and its tributaries correspond to high flood damage. This spatial analysis result is going to be prestigious key information to the regions and all related stakeholders for decisions and mitigation strategies.

Ecosystem service valuation is a crucial step for the sustainable management of watershed. In the context of various ecosystem services provided by watershed, this study, particularly deals with water yield computation in Bagmati Basin of Nepal. The water availability per population in Bagmati Basin is lowest compared to other basins in Nepal. Also, the rate of urbanization is rapidly growing over a decade. In this regard, the objectives of this study are 1) to compute the total water yield of the basin along with computation on a sub-watershed scale, and 2) Study the impacts of land use change on water yield based on CLUE-S model. For the study, Integrated Valuation of Environmental Services and Tradeoffs (InVEST), a popular model for ecosystem service assessment based on Budyko hydrological method is used to compute water yield. As well, CLUE-S model is used to study land use change, which is further related to study variation on water yield. The sub-watershed wise outcome of the study is expected to provide the guidelines for the effective and economic management of a watershed on a regional scale.

최근 지구온난화에 따른 기후변화로 인해 집중호우와 태풍의 영향으로 토석류를 동반한 산사태가 빈번하게 발생하고 있다. 산지에서 짧은 시간동안 강우가 집중되어 발생하는 토석류는 고수위의 홍수파를 형성하며 유목 및 흙, 자갈 등이 함께 유동하여 주변도로와 하류지역의 민가나 하천구조물에 큰 피해를 발생시킨다. 특히 강원도 지방도로의 경우 대부분이 산지와 급경사지로 이루어져 있어 집중호우시 산사태나 토석류에 매우 취약한 실정이다. 이러한 피해를 사전에 예방하기 위해 국내에서는 부처별로 다양한 풍수해 관련 재해지도를 작성하여 제공하고 있지만 표준모델이 없고, 서로 다른 형태의 지도를 관리하고 있어 재난 발생 시 도로관리에는 효율적인 활용이 어려운 실정이다. 따라서 본 연구에서는 재난 시 효율적인 지방도로 관리를 목적으로 다양한 재해지도의 중첩을 실시하였다. 또한 도로에서 빈번하게 발생하는 재해를 분석한 결과 산사태와 토석류가 높은 비중을 차지하였으며, 해당 재해지도를 중첩하여 지방도로 중심의 재해지도를 작성하였다.

In the field of forest disaster prevention, drones are expected to save higher human resources than the existing manpower has, and produce high-efficiency results over time. However, operational limitations brought by short flight times have brought the environment of limited use of the various capabilities of the drone, and the existing development systems operating the multi-drone are mainly for performance purpose, so it is a difficult to use for forest disaster prevention. The purpose of this paper is to design the concept based on multi-drone operation procedure through analysis of mission of ground control system for forest disaster prevention.
