References List: The list of references is recent, and all references are related to the research topic but it is not sufficient for this study. The names of the researchers must follow the style of the journal format. The double quotation should be omitted from the research titles in the list of references. Some search names in the reference list begin an uppercase letter for each word (such as [4], [5] ... etc.) and others use only an uppercase letter in the first word (such as [2], [9] … etc. ), authors should standardize style. All journal names should be italic. Some references do not contain enough information such as [16], [18] … etc. Some links do not work in the reference list like [22] … etc. The list of references requires an extensive check.
