Abstract: The present invention relates to a method and a system for recognition of objects near a ship by using a deep neural network to prevent a collision with the object by recognizing a neighboring object that may be risky to the ship sailing in a restricted condition such as a foggy environment. All object movements within a predetermined radius are detected and recognized so that collision accidents with objects on the sea in an environment such as fog caused by bad weather at sea can be prevented, and a risk alarm is notified to a captain when the object is detected so that collision accidents can be remarkably reduced. In addition, peripheral environments are detected by only installing a CCTV camera so that expenses can be reduced, human negligence can be prevented, and the system can be easily constructed to prevent collisions.

Abstract: Disclosed is a method of synthesizing graphene, wherein a Cu—Ni thin film laminate including a copper thin film and a nickel thin film formed thereon is placed in a chemical vapor depositor, brought into contact with a graphene precursor and subjected to chemical vapor deposition (CVD), thus synthesizing thickness-controlled graphene on the copper thin film, whereby the thickness of multilayer graphene can be easily and reproducibly controlled by adjusting only nickel thickness and CVD time, and a process window for obtaining reproducible results can be widened due to self-limiting properties whereby the maximum thickness of graphene is obtained after a certain synthesis time due to the thickness-controlled nickel thin film. Also, carbon atoms absorbed to the nickel thin film reach the copper thin film opposite thereto through internal diffusion of the metal laminate to thus grow graphene via surface-mediated reaction thereon, thereby improving the uniformity of synthesized graphene.
