3) Results: Results should be clear and concise. Dividing the results into proper subsections is recommended to improve readability.

4) Discussion: Academic discussion on research findings and relevant references should appear. It is also possible to compose a manuscript by integrating the “Discussion” section and “Results” section into a “Results and Discussion” section.

5) Conclusions: This is an optional section briefly explaining the critical conclusions of the study. The “Conclusion” section may also appear as a subsection of the “Discussion” section.

2.2 The manuscript file is written in Korean and English. In the case of Korean, the paper should be arranged in the following order: abstract (English), keywords (English, Korean), introduction, research methods (or materials and experimental methods), results, consideration (or results and considerations), conclusion, history, symbol explanation, references (English), tables (English), and figures (English). In the case of English, the order should be: abstract, abstract (Korean), key words, introduction, materials and methods, results and discussion, conclusion, acknowledgments, references, tables, and figures.
