Using Data

This study suggests the spatial scope of the regional hazard mitigation plan, reflecting the feature of natural hazards occurring beyond the administrative zone boundary. The damage caused by natural hazards is not randomly distributed across a space but has interdependent characteristics with the nearby area; therefore, the spatial influence of an adjacent area should be considered. In particular, as damage due to natural disasters is increasing in Korea, it is necessary to establish a regional hazard mitigation plan considering the spatial characteristics of hazards. However, the current hazard mitigation plan sets the scope of the plan based on administrative boundaries. In this study, we measured the vulnerability index of each area using data spanning 10 years from 2008 to 2017 and verified spatial correlations through LISA (Local Indicator of Spatial Autocorrelation). According to LISA analysis, we found that a link exists between si/gun/gu and we identified the spatial characteristics of natural disaster damage. The results confirmed that natural hazard characteristics occur beyond the boundaries of administrative areas.

Abstract Studied here are the results of the asymmetric problem solution of the thick walled circular cylinder elasticity using the spatial characteristics technique. The practical implementation of the solution of the problem is based on the calculation of the stress-caused deformation state of the stuck drilling string zone affected by the explosion wave action upon the inner wall of the pipe. Suggested here is the technique for determining axual σz and circular σθ stress on the drill pipe wall as well as the radial displacements ur of the stuck drill pipe outer surface under the action of the explosion shock wave. The above technique enables to make a sound selection of the cylindrical explosive charge weight in order to avoid the residual strain during the drilling string shaping off and uncoupling the threaded joints or to prevent them from exceeding the admissible level.
