Journal of Life Science
Instructions for Authors

1. Aims and Scope

The Journal of Life Science (J. Life Sci., JLS) is a monthly journal that aims to contribute to the development of life sciences in Korea and provide researchers with the latest research trends in the experimentally oriented life sciences by laying a platform for the presentation of high-quality research findings. The journal covers all scientific and technological aspects of biochemistry and molecular biology, bioactive materials, food sciences and microbiology, and biomedical sciences. However, the journal does not accept papers based on results that cannot be repeated or on simple observation.

2. Types of Contributions

JLS features 1) Original research papers, 2) Notes, and 3) Reviews. Original research papers should describe valuable new information and should be submitted in their final complete form. Notes can describe a finding in a specialized field, a new experimental method, or something similar that might not be suitable for publication as a regular paper but needs to be published. Notes should be less than four printed pages, including tables and figures. They should have the same style as full research articles. Reviews should focus on a topic of any subject that is within the scope of the Journal of Life Science. Normally, review articles will be invited by the Editor-in-Chief or managing editors; any person interested in submitting such a review should contact them. All submitted manuscripts will be reviewed by an editor and reviewers.

3. Submission of Manuscripts

All manuscripts should be written in clear, concise, and grammatically correct English or Korean; manuscripts that are inadequately prepared will be returned to the authors without further review. Manuscripts submitted to the journal should not have been published or offered for publication elsewhere. Manuscripts should be prepared in MS Word using Times New Roman 12-point font and double-spacing, and all pages must be numbered at the center of the bottom margin, with line numbering. Manuscript pages should have margins of at least 2.5 cm on all four sides.

All tables and figures should be assembled into a single file together with the main text for submission. All submissions to the Journal of Life Science must be made electronically via the Web-based online manuscript submission and review system (http:/article.jls.or.kr). Authors who are not confident of their English writing should have their manuscripts checked by an English-speaking copy editor. Information regarding acceptable types of files for submission can be found on the online submission page of the journal’s home page. All queries relating to the submission should be directed to lifes@jls.or.kr.

4. Review Process

All manuscripts are reviewed confidentially by members of the editorial board and qualified reviewers. When a manuscript is submitted to the Journal of Life Science, it is given a manuscript number and assigned to a member of the editorial board for review. The manuscript number should be referred to in any subsequent communication between the corresponding author and the editor or the Editorial Office. The reviewers operate under the “guidelines for reviewers” and are expected to complete their review within 3 weeks, or 2 weeks in the case of rapid reviews. The corresponding author is generally notified of the reviewers’ decision within 4 weeks of submission. When a manuscript is returned for revision, it should be returned to the editor within 60 days or it may be considered withdrawn. The authors should supply responses to the editor along with the modified or revised manuscript. Manuscripts that have been rejected or withdrawn may be resubmitted if the major criticisms have been addressed. As with an initial submission, resubmitted manuscripts should be accompanied by a cover letter stating that the manuscript is a resubmission and describing in detail what changes have been made. The same editor that handled the original submission will usually handle the resubmitted manuscript.

5. Proofs

Authors are responsible for ensuring that all manuscripts (whether original or revised) are accurately typed before

final submission. The proof will be sent electronically to authors before publication, and should be returned within 2 working days of receipt. The publishers reserve the right to charge for any changes made at the proof stage (other than printer’s errors) because the insertion or deletion of a single word may necessitate resetting of whole paragraphs.

6. Copyright & Authorship

To protect the Society’s ownership and the original authors from misappropriation of their published work, all authors agree to a copyright transfer when the manuscript is accepted for publication. The corresponding author signs for and accepts responsibility for releasing this material on behalf of any and all coauthors. Copyright of published papers belongs to the society. Copyright transfer can be found during the submission process via homepage (http:// article.jls.or.kr).

Authorship credit should be based on (1) substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data for the work; (2) drafting the work or revising it critically for important intellectual content; (3) final approval of the version to be published; and (4) agreement to be accountable for all aspects of the work in ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved.

7. Ethical consideration

All authors should ensure that they have written entirely original works, and if the authors have used the work and/or words of others, that this has been appropriately cited or quoted. Plagiarism takes many forms, from copying or paraphrasing substantial parts of another's paper (without attribution), to claiming results from research conducted by others. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Evidence or allegations of violations of the standard norms for publishing original research, including publication without approval of all authors, plagiarism, republication of data used previously without acknowledgement, and inappropriate image manipulation, will be investigated. All manuscripts found to contain violations are subject to any of the following actions: they may be rejected without scientific review; authors may be asked to withdraw an article after publication; the publisher may retract the article; and/or the matter may be referred to institutional officials. CrossCheck is a multi-publisher initiative to screen published and submitted content for originality. JLS uses CrossCheck to detect instances of overlapping and similar text in submitted manuscripts. To find out more about Cross Check visit www.crossref.org/crosscheck.html.

Once accepted, the manuscripts are not allowed to be reproduced in part of whole material without the permission from the journal secretary. The articles are not allowed to be reproduced for commercial purpose without the permission from the journal society. Research projects involving human subjects require review and approval by an Institutional Review Board (IRB). When reporting experiments on human subjects, authors should indicate whether the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation or with the Helsinki Declaration of 1975, as revised in 2008. IRB approval number must be cited in the Materials and Methods section of the text. When reporting experiments on animals, authors should indicate whether the institutional and national guide for the care and use of laboratory animals was followed. Any unusual hazards inherent in the chemicals, equipment, and procedures used in an investigation should be clearly identified in the manuscript reporting the work.

8. Paper Charges and Reprints

Page charges are currently 40,000 Korean won (US$ 40.00 or eqivalent) per page and manuscript handling fee are 40,000 Korean won per manuscript. Printed journal will not be provided to authors starting from the issue of June, 2020.However, a separate reprint version will be available based on the beneficiary burden principle. If an important error is discovered after publication, it should be brought to the attention of the editorial section so that an erratum can be published. If the error was made by the author, the costs of publication of the erratum will be charged to the author.

9. Preparation of Manuscripts

(Style) The text should be arranged in the following order: Title, Abstract with five keywords, Introduction, Materials and Methods, Results, Discussion, Acknowledgments, Nomenclature, References, Figure legends, Tables, Figures, and translated abstract (with title, author names, and affiliations) written in Korean. A cover letter stating the title of the manuscript, names of the authors, complete mailing address(es), and telephone and fax number(s) of the corresponding author should be included.

The title page should include the title, author name(s), and affiliation(s), including the complete address(es) for correspondence. The title should be written exclusively in English, with no running title. Title words, except prepositions and articles, should be properly capitalized. Avoid use of abbreviations and acronyms in titles. The corresponding author(s) is to be marked by (*). When there is more than one “first author,” this should be indicated in a footnote (e.g., Gildong Hong and Sunshin Lee contributed equally). Pagination should start from the title page.

The abstract should be written exclusively in English, even if the manuscript is written in Korean. The abstract should be provided with one single paragraph of 200-250 words for original research papers and reviews, and 150-200 words for notes. All abbreviations used only once or for the first time must be spelled out. Keywords should be presented in alphabetical order and must follow the abstract on the same page.

Abbreviations and acronyms, if any, should be spelled out the first time used, and placed in parentheses after the full term. Terms defined in the abstract should be defined independently in the main text.

Introduction (in bold) should state (1) the purpose of the research and (2) its relationship to other work in the field.

Materials and Methods (in bold) should provide all details necessary to allow repetition of the work, and manufacturers or sources of materials should be cited. Subheadings (in bold) should start with indentation and end without a period. Subheadings should be separated from the text by a blank line. Neither third-level subheadings nor numbered headings are allowed.

Results/Discussion (in bold) should be separated ordinarily. However, they may be combined (e.g., Results and Discussion) to make the presentation clearer.

Acknowledgments (in bold) are placed at the end of the Results and Discussion.

References
must include all relevant published works, and all listed references must be cited in the text. Journal names should be abbreviated according to the ISO abbreviations (http://www.ncbi.nlm.nih.gov/nlmcatalog/ journals). References should be listed in alphabetical order beginning on a new page and cited in the text with Arabic numerals in parentheses, e.g., [1], [2, 3], [4, 27, 35], and [8-10].
