Here is the procedure:
The abstract should be concise, factual, and state briefly the purpose of the research, the principal results and major conclusions. An abstract is often presented separately from the article, so it must be able to stand alone. For this reason, References should be avoided. Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.
Abstract contains neither picture nor tables, justified, italic in 11 Times New Roman (font), single spaced, and should not exceed 350 words.
Keywords should be justified, 10 Times New Roman (font), single spaced, and maximum 5 keywords.
