The snow brings affluence if it is dealt with appropriately. but causes huge damages if it is dealt with improperly when it snows heavily. Following with the development of road transportation, tile snow causes damages by becoming a serious obstacle for traffic, increasing traffic accidents, causing damages to the road, and requiring a lot of snow removal expense. As farming in the winter becomes flourishing, damages to agricultural facilities and farm produces caused by the snow become bigger and bigger. Now in our country, heavy snow or heavy rain is likely to fall at anywhere and at any time without restricted to a particular area. Safety first is one way of practicing human respect. Disasters will disappear from our neighborhood if we adopt prevention measures and follow them thoroughly. And also this is the shortcut to achieve a welfare society.
