Convert tightly coupled local variable inside of method into method arguments

As the previous PR #382 and #379.
I find several other samples that have the tendencies of including tightly coupled
variable for each of specific method. 

**Describe the solution you'd like**
Hence I think it will be better to pass it as an argument instead of simply using local variable inside of the method.

**Describe alternatives you've considered**
N/A

**Additional context**
N/A
