Walls for preventing floods using overturning or buoyancy method have been developed as replacement construction for preventing floods in and outside country. However, as they have some problems with pre-inspection and maintenance control, Eco-moving wall structure for preventing floods was studied and first developed using Glass Fiber Reinforced Composite which has not only light weight but outstanding strength. The developed wall structure for preventing floods offering structural stability and field applicability through numerical analysis was confirmed to reduce construction expenses by around 87~95% and secure waterproof property with the inside of the wall installed rubber water stopper.

The current streetlight system have been tried various attempts. but during maintenance, it has caused the traffic congestion and many risk factors. In addition, maintenance costs are very expensive to manage and the local government have to establish countermeasures about the present condition. If neglected, it may cause a variety of social problems. so, there should be a measure to prevent problems. This rotational and up-and-down type streetlight can be a solution to these factors and it has been highlighted indirectly in terms of green growth because we have to take advantage of the value.
