Submission of Manuscripts

Manuscripts should be submitted directly via KJOAS online manuscript submission and review system. Technical difficulties can be resolved by contacting to: The Research Institute of Agricultural Science, Chungnam National University, 99 Daehak-ro, Yuseong-gu, Daejeon 34134, Korea (Phone: +82-42-821-6710, Fax: +82-42-821-8890, Email: cnuagro@cnu.ac.kr).

Manuscripts are to be submitted in their final form and must be written in English or Korean, and authors are urged to aim for clarity, brevity, and accuracy of information and language. Authors whose first language is not English should have their manuscripts checked for linguistic accuracy by a fluent English speaker. Using the KJOAS template available at http://www.kjoas.org would be helpful for meeting the journal’s formatting requirements. A properly completed “Copyright Transfer Agreement” should also be supplied before the manuscript is published. All Authors including the corresponding author are asked to sign it.

Editorial and Review Policy

Editorial policy

Manuscripts submitted for publication should contain no materials that violate any copyright. Submission of a manuscript to KJOAS involves the tacit assurance that no similar paper has been or will be submitted for publication in other journals. Manuscripts that have been published in a conference or meeting proceedings without peer review may be submitted to KJOAS.
It is the responsibility of the authors, not the IAS, to determine whether disclosure of their material requires the prior consent of other parties and to obtain that consent. Statements and opinions given in work published by KJOAS are the expressions of the authors. Responsibility for the contents of published papers rests upon the authors, not the IAS.

Publication type

KJOAS accepts the following types of manuscripts: original research articles, review articles, and technical notes. An original research article represents an original, important contribution to all agricultural science including crop and plant science, forestry, animal science, food science, chemistry, engineering, business and economics. The manuscript should clearly state the scope and purpose of the research work. The information presented must be objective and well organized, and the conclusions should be adequately supported. Review articles should be a critical evaluation of the existing state of knowledge on a particular aspect of agricultural science. Simple literature surveys will not be accepted for publication. Technical notes should be brief descriptions of the development of devices, equipment, techniques, or applications that offer definite advantages in research or practice over those already available.

Peer-review process

All manuscripts are subject to peer review for the validity of the experimental design and results, significance, and appropriateness for KJOAS.
When manuscripts are submitted successfully to the journal online system, they are initially subjected to a pre-screening step by the Editor-in-Chief. Manuscripts that are poorly written or fail to meet the required format will be rejected in the pre-screening step without further review. Manuscripts that pass this step will be reviewed by two anonymous reviewers selected by the Editor-in-Chief or associate editors. The corresponding author is notified as soon as possible regarding the decision to accept, reject, or request revision of a manuscript. The manuscripts evaluated as “accept” or “request minor revision” by the reviewers are considered to be accepted for publication, although some revisions may be required to address the concerns of the reviewers and Editor-in-Chief. In cases where a manuscript is evaluated as “make major revisions” or “reject” by one of the reviewers, the Editor-in-Chief will analyze the reviewers’ comments thoroughly and make a decision on acceptance or rejection. If there are major flaws in the results of the research or the methodological design, the Editor-in-Chief may ask the author to clarify and resubmit or may reject the manuscript. If a manuscript is classified as “accept with revisions,” the author is expected to respond within 3 months, addressing all the comments raised by the reviewers, making appropriate corrections or stating why the comments are unreasonable. The responsible editor or a reviewer will consider the revisions, and recommend that the Editor-in-Chief either accept the manuscript for publication or reject it. The author will be informed by the Editor-in-Chief of the final decision on the publication of the manuscript.
When the final revised manuscript meets all KJOAS content and format requirements and has been accepted for publication without additional revisions, it is scheduled for publication in the next available issue.

Page proofs

This proof stage is not a time for extensive corrections, additions, or deletions. It is advised that editing be limited to the correction of typographical errors, incorrect data, and grammatical errors, and for updating information on references that had been in press. The corrections to page proofs should be sent immediately by e-mail preferably within 2 business days.

Page charges

The KJOAS Editorial board charges a publication fee of 200,000 KRW ($200 US) to the authors when a submitted paper is confirmed for publication.

Organization of the Manuscript

The manuscript should be organized in the following sequence.
Title and Authorship
Abstract and Keywords
Introduction
Materials and Methods
Results and Discussion
Conclusion
Acknowledgements (optional)
References
Appendix or Nomenclature (optional)

1. Title and Authorship

The title should communicate key information about the article’s content. The list of authors should include the full names and institutional affiliations of all the authors. The name of the corresponding author should be marked with an asterisk. The e-mail address of the corresponding author should be provided on the first page.

2. Abstract and Keywords

The abstract should summarize the most important points from the text of the article. It should include the purpose of the research, a brief description of the experimental methods, a summary of the significant results, and major conclusions or implications of the findings for research or practice. The method and results should be presented as specifically as possible within the constraints of the word limit. The abstract of the paper should have a length between 200-250 words. Less than five keywords should be listed for indexing purpose.

3. Introduction

The introduction should be used to review the published literature and issues related to the topic. A thorough introduction will help the reader recognize how the research contributes to the current knowledge in the subject area. Thus, the introduction should include a literature review, a description of the problem addressed by the study or the gap in current research findings, and the purpose of the study.

4. Materials and Methods

Information about materials and methods should be provided in enough detail to allow a competent researcher to repeat the experiments and verify the results. In the materials section, material preparation, specification of the materials, and equipment used in the experiments should be described. The source company of materials, equipment, and software should be stated parenthetically along with the model name, the city, the state or province, and country of the company. The experimental procedure and the data analysis methods should also be stated in this section.

(Description of participants)
Ensure correct use of the terms sex (when reporting biological factors) and gender (identity, psychosocial or cultural factors), and, unless inappropriate, report the sex and/or gender of study participants, the sex of animals or cells, and describe the methods used to determine sex and gender. If the study was done involving an exclusive population, for example in only one sex, authors should justify why, except in obvious cases (e.g., prostate cancer). Authors should define how they determined race or ethnicity and justify their relevance.

5. Results and Discussion

A solution to the problem stated in the introduction should be provided in the results and discussion section. Tables and figures are commonly used to visually show the results. Rather than restating the entire content of tables and figures, only the critical data can be restated in the text to emphasize evidence on which the conclusions are based. The data should also be interpreted in this section. Because the results and discussion are combined, the author may choose to address each finding and then discuss it before moving on to the next point, or present the results followed by the discussion. The discussion should include a comparison with previous findings by identifying how and why there are differences and where there is agreement. Any limitations of the study should be addressed.

6. Conclusion

The main findings of the research should be summarized in the conclusion section. This section should not contain extensive repetition of the Results and Discussion section or reiteration of the Introduction section.

7. Acknowledgments

The sources of financial or material support can be listed in the acknowledgements section. Also, any individuals whose contributions were significant but not deserving of authorship should be described.

8. References

There must be a text citation for each reference and vice versa. The required method for giving references in the text is the last name-publication year system as in Kim (2003) or (Kim, 2003), depending on whether the author is mentioned in the sentence or not. For two authors, the format of Kim and Lee (2010) or (Kim and Lee, 2010), and for three or more authors, Kim et al. (2000) or (Kim et al., 2000) should be used. When more than two references are cited for the same content, they should be arranged alphabetically. The references cited in the text should be listed in the reference section in alphabetical order of the last name of the first author. The references published by the same author in the same year are indicated by placing a, b, and so on, next to the publication year (e.g. 1999a, 1999b, etc.).
