Reinforced Concrete) structure is as following.
1) high economic performance
2) because resources expense is inexpensive than steel-frame structure) corrosion resistance that prevent corrosion of interior reinforcing rod because is alkalinity is security
3) have excellent modeling.
4) ability that have high hardness and stand in shock of pedestrian or machine operation etc. is big.

1 Introduction
When designing an aircraft, it’s all about finding the optimal proportion of the weight of the vehicle and payload. It needs to be strong and stiff enough to withstand the exceptional circumstances in which it has to operate. Durability is an important factor. Also, if a part fails, it doesn’t necessarily result in failure of the whole aircraft.
The main sections of an aircra

In these days, the boundaries between off-line and on-line are collapsing. We call that 2000s as media scramble, 2010s as new media order. There are many different things in these two times. There are many features that reveal the differences between media scramble and new media order. For example, in competition composition, there are only two competitors (internet company, media company) in 200
Protection risk factors. Internal DU exposure is acknowledged to cause kidney damage, cancers of the lung and bone, respiratory disease, neurocognitive disorders, chromosomal damage and birth defects.
Despite of above, environmental problem has low priority than other problem. But, environment is shared resource in the world. So, we have to try to solve these environmental problems.
