All published materials are also assigned a Creative Commons Attribution License (https://creativecommons.org/licebses/by-nc/3.0/). The Journal accepts manuscripts for consideration with the understanding that the manuscript has not been published previously and is not currently under consideration for publication elsewhere, and in addition the authors (or their employer, if it holds the copyright) are authorizing the transfer of the copyright to the Institute, when the manuscript is submitted.
Authors, editors, and publisher all have ethical obligations with regard to the publication of the results of research. For the policies on research and publication ethics that are not stated in these instructions, please refer to the Committee on Publication Ethics (COPE) Guidelines (http://publicationethics.org/resources/code-conduct).
Authorship should be credited based only on substantial contributions to conception and design, or analysis and interpretation of data, and drafting the article or revising it critically for important intellectual content, and final approval of the version to be published. All authors are responsible for the accuracy, quality, and ethics of the work. After the initial submission of a manuscript, any changes whatsoever in authorship (adding author(s), deleting author(s), or re-arranging the order of authors) must be explained by a letter to the editor from the authors concerned. The content of this letter must be acknowledged and agreed by all authors of the paper.
2.2 Conflicts of Interest
If there are any conflicts of interest, authors should disclose them in the manuscript. Examples of potential conflicts of interest are financial support from companies, connections to companies, and political pressure from interest groups. In particular, all sources of funding applicable to the study should be explicitly stated.
2.3 Overlapping Publications
All submitted manuscripts should be original and should not be considered by other scientific journals for publication at the same time. Any part of the accepted manuscript should not be duplicated in any other scientific journal without the permission of the Editorial Board. If duplicate publication related to the papers of this journal is detected, the authors will be announced in the journal, their institutes will be informed, and the authors will be penalized.
Plagiarism is the use of others' published and unpublished ideas or words (or other intellectual property) without attribution or permission, and presenting them as new and original rather than derived from an existing source. Plagiarism is scientific misconduct and should be addressed as such. If some part of the article is published elsewhere in print or online by the authors, it should be stated. The editors should make decisions about a manuscript based only on its importance, originality, clarity, and relevance to the Journal's scope and content. If there are any ethical issues from the manuscripts, it should be first reviewed by Editorial Board and the recommendation should be processed by the supporting Institute.
All correspondence concerning submission is between the contributors and the Editor-in-Chief. The Journal receives manuscripts only through the electronic submission system, e-submission at http://www.ijfis.org/. The system provides the standard submission process in steps, and asks the contributors to upload manuscripts in the PDF or Microsoft Word files for review along with the scanned copyright transfer form. The contributors are kindly asked to use the standard submission formats provided in the following links, MS-Word and LaTex. The contributors can keep track of the stage of review process on the electronic submission system.
Review management is under the direction of an editor who will solicit three reviews for each submission. The editor will ordinarily wait for at least two reports before a decision is reached. The review process can be repeated till three times if the request of revision is suggested by reviewers. If the review is repeated more than three times, it may not be considered for publication. If two reviewers do not agree to accept the article, it may not be considered for publication.
The Journal publishes papers under 5 categories: regular papers, correspondence, review papers, technical report, editorial, book review.
• Regular papers normally have a length of 6–10 pages of A4 size papers to report original research results or a well-focused survey on specific theories. Longer manuscripts will be considered, but have a proportionately lower probability of acceptance.
• Correspondences are reports of preliminary results or short reports on completed works that are of current interest to many researchers in the field. Comments on material previously published in the Journal, suggestions for new directions, and errata could be included. Their lengths must be less than 4 pages.
• Review papers will be published by direct submission as well as from invited experts. In both cases, the work will be subject to editorial review. Review papers should critically review topics not only to inform the reader of the background, but also to communicate the state of the art and outstanding research problems. A review is organized as follows: title page including abstract and keywords, introduction, body text, conclusions or summary, acknowledgments, and references. Their lengths must be less than 10 pages.
• Technical reports are articles in this category introduce scientific work on novel skills dealing with new methods and techniques with results obtained from the methods.
• Editorial is an invited perspective in fuzzy logic and intelligent systems theory, dealing on very active areas of research, fresh insights and debates.
All manuscripts should be written in good English. This is the responsibility of the authors, not the editors. Contributors for whom English is not a native language are recommended to get professional helps for English prior to submission. The electronic submission system (http://www.ijfis.org) provides the standard formats for manuscripts in MS-Word and LaTex. All manuscripts should be prepared according to the following guidelines.

Each Table should include column heads, footnotes, and data. The table should list all abbreviations in the table in footnotes at the end. Tables should be numbered according to their order of mention in the text. Each table must be submitted as an electronic file. Omit internal horizontal and vertical lines. A title of table is concise and describes the table’s contents. The table should be self-explanatory and supplement, not duplicate the text. If the table or any data therein have been published, a footnote to the table must give permission information to the original source. The structure should be clear, with simple column headings giving all units. A table should not exceed one page when printed. Use lower case letters in superscripts a), b), c) ... for special remarks. Unaltered computer output and notation are generally unacceptable.
6.6 Figures and Legends for Illustrations
Figures are numbered consecutively in the sequence mentioned in the text and must have a caption written in one paragraph style. The caption should contain an explanation of all abbreviations and symbols used, and indicate the size value of lines or bars unless shown directly on the figure. In multi-part figures, the legends should distinguish (a), (b), (c), etc., components of the figure. Figures should be submitted as Tiff or EPS file format. If the only possible file format is JPEG, it must be in highest quality with minimum compression. It is recommended to size original figure widths to 4 inches wide. The minimum requirements for digital resolution are:
• 900 DPI/PPI for black and white images, such as line drawings or graphs.
• 300 DPI/PPI for picture-only photographs.
• 600 DPI/PPI for photographs containing pictures and line elements, i.e., text labels, thin lines, arrows.
The Acknowledgments section is the general term for the list of contributions, disclosures, credits, and other information included at the end of the text of a manuscript but before the references. Co-workers and others who contributed significantly to the current study, but were not co-authors, should be mentioned in the acknowledgements. All sources of financial and other support should also be stated. Authors must obtain written permission to include the names of all individuals included in the Acknowledgments section.
6.8 Units and Abbreviation
If authors describe length, height, weight, and volume, they should use standard metric units. Temperature should be given in degrees Celsius. All others should follow the International System of Units (SI). All units must be preceded by one space except percentage (%) and temperature (°C). Abbreviations must be used as an aid to the reader, rather than as a convenience of the author, and therefore their use should be limited. Generally, avoid abbreviations that are used less than 3 times in the text, including tables and figure legends. Standard SI abbreviations are recommended. Other common abbreviations are as follows (the same abbreviations are used for plural forms): h (hour), min (minute), s (second), d (day), wk (week), mo (month), y (year), L (liter), mL (milliliter), μL (microliter), g (gram), kg (kilogram), mg (milligram), μg (microgram), ng (nanogram), pg (picogram), g (gravity; not g), nm (nanometer), μm (micrometer), mV (milivoltage), mA (miliampere), mW (miliwatt), C (coulomb), μF (microparad), mH (milihenry), n (sample size), SD (standard deviation of the mean), and SE (standard error of the mean).
6.9 Mathematical Notation
For convenience of citation of equations, authors are encouraged to number all displayed equations. Equations should not be referred to by their numbers alone; e.g., say "substituting in Eq. (21)" rather than "substituting in (21)." Mathematical notation should be clear, distinct, and consistent throughout the manuscript. Care should be taken to distinguish between O (capital oh), o (lower-case oh), and 0 (zero); l (alphabet el) and 1 (one); ε (epsilon), and ∈ (set membership symbol); k (italic kay) and κ (Greek kappa); v (italic vee) and ν (Greek nu); and φ (Greek phi) and ∅ (empty set symbol). Vectors are normally distinguished by bold lower case type (e.g., b); arrows over symbols are not recommended to denote vectors. Matrices are normally distinguished by bold upper case type (e.g., M). If other fonts are needed to distinguish functions or other operators from italic (R), script (calligraphic) characters (ℛ) are preferred.
7.1 Format of Final Contributions
Upon acceptance of an article, the author or authors are asked to submit the final manuscript. The contributors are kindly asked to use the standard submission formats provided in the following links, MS-Word and LaTex.
7.2 Manuscript Editing
The finally accepted manuscript will be reviewed by manuscript editor for the consistency of the format and the completeness of references. The manuscript may be revised according to the opinion of the manuscript editor.
7.3 Page Proofs
Authors will be given an opportunity to review the laser printed version of their manuscripts before printing. One set of page proofs in PDF format will be sent by e-mail to the corresponding author. The review should be solely dedicated to detection typographical errors. Editorial changes and corrections are not to be made at that time. To meet production deadlines, a rapid turnaround of these proofs is necessary.
The corresponding author is charged US50.00 each extra page, for his accepted manuscript. The published articles are open accessible on the web http://www.ijfis.org. The members of Korea Institute of Intelligent Systems receive the journal issues in print.
