Generally, virtual machine platform is composed of a compiler, an assembler, and VM(Virtual Machine). To develop it, the design of VMC(Virtual Machine Code) is an essential task. And it is very important to verify the virtual machine platform. To do this and furthermore to execute VMC, it needs to implement VMC execution system using compiling method, interpreting method, or decompiling method. In this paper, we suggested and implemented the executing system of VMC using decompiling method out of three methods to execute the VMC. In our implementation, the VMC is SIL(Standard Intermediate Language) that is an intermediate code of EVM(Embedded Virtual Machine). Actually, we verified the usefulness of the decompiling method. And the decompiling method suggested in this paper can be used to minimize the mistake in developing Virtual machine platform.

Although pipe performs various functions in industrial sites and residential spaces, if it is damaged due to corrosion caused by the external environment, it may cause equipment failure or a major accident. For this reason, various studies for safety management are being conducted, but studies on detecting corrosion or cracks on the pipe surface using a laser displacement sensor have hardly been conducted. Therefore, in this study, the corrosion degree of the pipe surface was compared and classified into 4 corrosion conditions, and inspection equipment using a laser scanner was manufactured. The corrosion height was calculated from the four surface data obtained from the measuring equipment and applied to various CNN algorithms, and 91% accuracy was obtained during training using the Modified VGGNet16 code with reduced number of parameters.

Construction equipment plays an important role as one of resources in construction process. It is obvious that the machine intensive construction method achieves productivity and quality improvement as well as safety improvement. The number of registered construction equipment in Korea is over 320,000 in 2005 according to the national statistics safety, but recent crisis of construction equipment industrialist has been deepen by lack of skilled workers, rise in wages, diminution of working and etc. The main objective of this paper is to propose an improved management and application policy for the better construction equipment utilization. A classification method for construction equipment and a licensing system for construction equipment operators are newly suggested to revise the Construction Equipment Management Law. In order to satisfy the objective, this research performs literature reviews on domestic and overseas related laws and regulations for operating license, and conducts surveys and interviews with experts in the field of construction equipment industry. The results of this research can be considered as an important reference to update the Law that can improve construction productivity and equipment operating rate.
