Manuscript’s Structure

The manuscript should have to be formatted in Microsoft Word, not exceeding 7,000 words (about 15 pages typed in A4 size including references).
Margin left 3 cm, right 2.5 cm, top 2.5 cm, bottom 2.5 cm. The authors should have to use Unicode code, Times New Roman font, font size 12; spacing: single line, before: 6pt, after: 0pt; justified text. The first line of each paragraph should be indented by one-tab space (0.5 in or 1.27 cm).

A manuscript could have various structure but must ensure all the necessary contents of a complete research. A scientific manuscript usually includes the following sections:

1.    Introduction

The introduction should be precise with no subtitles, mentions the research’s the necessity, the research’s objectives, the expected theoretical and practical contributions, and the research innovations.

2.    Theoretical basis

This part presents the basic theories/thesis and clarifies the views related to the manuscript.

The part presents the summary of other pieces of research (Authors, years, name of the study, methods, and the results).

Based on that, the authors would propose a research model, an analytical framework, or research assumptions for their work.

3.    Research method

Based on the identified research models, the analytical framework, or the research hypotheses, the research specifies the appropriate analytical methods/ research models to produce scientifically sound results.

The scope of the research is presented clearly through methods of data collection; these methods also describe in detail how to measure variables in the study.

Sources of data must be fully and reliably cited.

4.    Research results

The research findings could be from qualitative and quantitative analysis. This part also indicates the difference of the research results of the study compared with other previous relevant studies, identifies the scientific & practical contributions, limitations of research, and proposals for further studies.

The study should only discuss what has been stated and defined in the manuscript; the results will directly support the conclusion.

5.    Conclusion

Conclusions are driven directly from the results of the study after contrasting with previous studies’ research objectives. The policies, solutions, proposals are practically recommended based on the results of the research.

The authors employ "Figure" to describe all images, charts, maps, flowcharts, etc. used in the manuscript. They must be centered and placed immediately after the content referring to them. The images used in the manuscript must be clear and of good quality. The figures’ title must be set below the image and numbered with the Arabic system.

"Figure" which is in bold, lowercase, and only the first letter is capitalized. The title of the figure (not bold, lowercase, except the first letter) will immediately follow the word "Figure" after a period. Units should be included in the figure.     

                                                                                                  Figure 1. The title places on the bottom of the figure


Note & Source

Note: The notes (if any) place at the bottom of the table/figure, font size is 10, justified text, integrated into the table/figure.

Source: font size is 10 and located at the bottom, left corner of the table/figure



Any equations should be editable texts, not images. Equations should be numbered consecutively (numbers are in parentheses) on the right side of the page and mentioned as equations 1,2, etc.. The fractions are displayed in one line; a [/] sign separates the numerators and denominators. Additionally, any more complex equations should be shown using the equivalent software.




Measurement units must be presented accurately by using the International System of Units (SI).
