1. 서론
The wingbone is an important factor in determining the air force characteristics of an airplane's wing. There are many types of wing bones, but it was by NACA, the predecessor of the U.S. space agency, that systematically designed them. Currently, most of the wing bones are classified as four-way, five-way, six-way and supersonic wing bones, which are called NACA standard wing bones. T

1. Summary
Vending machines are comfortable in that they provide goods without human interactions and can be operated 24/7. Also, they minimize the workforce and bring benefits to the maximum. As one-stop shoppers are skyrocketing, the aspect of vending machines that they are not limited by time and space is becoming prominent. Hence, many different kinds of vending machines which target diff
