3. Manuscript Preparation

A. Article types

JEEM publishes four categories of publications: original article, review article, technical report, rapid communication, and letter to the editor. All submissions undergo a rigorous peer review process. Additional publication types may be considered in consultation with the editorial office.

Academic Progress Report: Review articles, which is overview and perspective statements on the research progress in a specified field by senior researchers. It is whether invited or submitted, should offer a thorough and comprehensive analysis of specific topics, synthesizing current knowledge and identifying future research directions.

Tutorial Status Report: Practical guides to fresh researchers for experimental setups and property measurements. It is whether invited or submitted, should offer important insights into specific protocols, methods, or case studies.

Regular Paper: Original research articles should present a comprehensive investigation and draw clear conclusions that contribute to significant findings in the field, which is bound for the scope of the journal.

Early Stage Report (Graduate Research / Undergraduate Research): Experimental results insufficient for regular article but good enough to contribute to the research database, failed results that help preventing other researchers from repeating the same failure, and undergraduate research works awarded by the KIEEME annual meetings.

B. General requirements

Language Requirements: Papers can be submitted in English or Korean. However, for those written in Korean, it is mandatory that the abstract, keywords, illustrations (tables/figures), and bibliography are provided in English.

Formatting Standards: The manuscript must be uploaded in Microsoft Word format, while image files (figures) should be submitted separately. The document layout requires A4 paper size (210 × 297 mm) with 2.5 cm margins on all sides. Use an 11-point Times New Roman font and ensure the entire text is double-spaced.

Measurements and Terms: Authors must consistently apply SI units throughout the text. The use of abbreviations should be kept to a minimum; at the first instance of use, the full term must be written out followed by the abbreviation in brackets.

Policy on Generative AI Technologies: Authors may utilize generative AI platforms (such as LLMs, chatbots, or image generators) solely to improve the clarity and linguistic quality of their writing. However, the following regulations must be observed:

• Disclosure Protocol:

• o General language editing or readability enhancements using AI do not typically require disclosure at submission.
• o Statistical Analysis: If AI tools assisted in performing statistical calculations, this must be reported. Authors should specify the software details (name, version, and provider) and explain the methodology.
• o Data Generation: Any data produced or simulated by AI must be clearly identified, noting the specific tool used and its function in the process.

• Drafting Restrictions:

• o While AI can refine existing text, it is strictly forbidden to use these tools to compose or draft the manuscript. Authors must not delegate the writing of significant sections or the entire paper to AI.

• Submission Integrity:

• o Upon filing, authors are required to confirm that the manuscript draft was not produced by AI. This ensures that the authors maintain full intellectual ownership and accountability.
• o Authors must guarantee that AI-assisted content is free from plagiarism. The final responsibility for the work’s validity and ethics rests entirely with the authors.

• Referencing AI Content:

• o AI-generated material is not permitted as a primary citation in the References list. Any such content used for analysis must be presented as supplementary data.

Keywords: Provide a maximum of five relevant terms at the end of the abstract.

G. Main Text Structure

Original articles should be organized using these specific headings: Introduction, Experimental Section, Results and Discussion, and Conclusion. Technical reports follow a slightly different structure: Introduction, Technique, Results, and Discussion.

Guidelines for Original Articles:

Introduction: Offer a concise background of the study, citing essential literature. Clearly state the findings of previous research and define the specific goals or questions your study aims to answer.

Experimental Section: Provide enough technical detail to allow for exact replication. Reference established protocols and describe any modifications made. Only provide extensive details for significantly new procedures. For standard techniques, briefly identify the method used and provide the relevant citation. New methods require a thorough, detailed explanation.

Results and Discussion: Report your findings clearly, avoiding redundancy with other sections. Interpret your data by comparing it with existing literature and within the scope of your experimental design. Subheadings may be used to enhance organization.

Conclusion: Provide a brief summary of the study's primary outcomes and its most important conclusions.

H. Mathematical Formulae

Submit all mathematical equations as editable text rather than embedded images. Every equation should be numbered chronologically using Arabic numerals, with the number enclosed in parentheses and justified to the right margin.

Ex) $f=f_{\mathrm{\infty }}+(f_0-f_{\mathrm{\infty }})\exp (-{\gamma }_r/{\tilde{\gamma }}_r)$         (1)

K. Tables and Figures

Tables
Tables must be formatted to stand independently from the text, ensuring clarity and data integrity.

• - Placement & Numbering: Start each table on a new page. Number them sequentially (Table 1, Table 2, etc.) according to their citation order in the manuscript.
• - Titles & Notes: Place the title above the table and any explanatory notes below.
• - Content: Avoid duplicating data already presented in the text or figures. Clearly define all units of measurement.
• - Formatting: * Minimize the use of vertical (longitudinal) lines. Use alphabetical symbols for footnotes in the specific order: $a), b), c), d), e), f). List all abbreviations alphabetically within the footnotes.
• - Citations: For previously published tables, the original source must be cited in the footnote.

Figures
High-quality visual data is essential for technical publication.

• - Resolution & Quality: Color and grayscale images must be at least 300 dpi. Line art should be crisp, high-quality black-on-white graphics.
• - File Formats: Submit each figure as an individual file in PPT, JPG, GIF, or PDF format.
• - Legends: Do not place legends within the image file. Instead, list them after the reference section in the main manuscript. Legends must be comprehensive, including stain types and magnification levels for micrographs.
• - Consistency: Figure numbering must strictly follow the order of mention in the text.

Permissions
Authors are responsible for securing usage rights for non-original content.

• - Copyright Clearance: Obtain formal permission via the Copyright Clearance Center or the original publisher for any modified or reprinted materials
• - Open Access: Materials from Open Access journals (Creative Commons) do not require formal permission but must be properly credited in the footnotes
• - Note: "Free-access" journals are not the same as "Open Access"; the former still requires explicit publisher permission.

L. Graphical Abstract

The Graphical Abstract should feature a high-impact original figure—either 60 X 50 mm or 100 X 40 in size—that clearly communicates the study's primary message, accompanied by a concise 30–50 word summary of key findings tailored for a general audience. While authors may incorporate existing manuscript elements, they must hold the copyright for all visual content and are encouraged to design a unique illustration for maximum clarity; otherwise, they will be required to designate a representative figure from the paper to fulfill this requirement.

4. Manuscript Submission

Authors are encouraged to submit their manuscripts through the official JEEM online portal (https://submit.jeem.org/), which offers a streamlined, step-by-step submission workflow upon user registration. Detailed guidelines are provided on the website to ensure all technical requirements are met; however, if any difficulties arise during the process, the editorial office is available for support via email at manage@kieeme.or.kr.

6. Final Preparation for Publication

A. Post-Acceptance Processing

Upon final acceptance, manuscripts undergo professional editing, after which a proofread version is dispatched to the corresponding author for a thorough review. Authors are expected to scrutinize the text for any remaining misspellings or technical inaccuracies; please be advised that a delayed response at this stage may result in the publication being rescheduled for a subsequent issue.

B. Galley Proof and Final Verification

Following the initial corrections, authors will receive a final PDF galley proof for a definitive quality check. A strict deadline of five working days is provided to notify the editorial office of any lingering errors regarding the title, affiliations, figure positioning, or reference list. While the corresponding author may request multiple revisions if necessary to ensure precision, they bear full responsibility for the accuracy of the final content once the manuscript proceeds to print.

7. Discussions After Publication

To address inaccuracies in published articles, the corresponding author must submit a comprehensive description of the necessary changes to the editorial office. Depending on the nature and origin of the error, corrections will be formally processed through one of the following mechanisms: an erratum for publisher-related mistakes, a corrigendum for author-related errors, or a retraction in cases where the findings are no longer considered reliable.
