as your suggestion, i used “cudaStreamSynchronize” function, however nothing to channge.
Even I don’t know if i correctly used the function 
i think i didn’t get cuda Stream from “getCurrent CUDA Stream” function.
Because stream variable look like empty as 2nd screenshot.
Should I make the stream to input data for using cudaStreamSynchronize?
Result
