Research articles to be published in SAUJS should not be longer than 20 pages, including references, appendices, figures, and tables, and review articles should not be longer than 30 pages. Tables and figures should be added directly to the article near where they are cited. Both tables and figures should be numbered sequentially. Tables and Figures should not be renumbered for each section in the article. The article should be written in Microsoft Word. It is important that authors follow the instructions.

You can find more details and suggestions on formatting an article in the author guide below, presented in a typical article style.

This document is adapted from previous style guides used for “Sakarya University Journal of Science (SAUJS)”. Please write your articles using this style guide.

Page Limit
Research articles to be published in SAUJS should not be longer than 20 pages, including references, appendices, figures, and tables, and review articles should not be longer than 30 pages. The abstract should not exceed 300 words.

Spelling and Grammar
Please check your document for spelling and grammar before submitting it.

Page Margins
The first page containing the Title and Abstract should be 5 cm from the top and 2.5 cm from the bottom, left and right. Left and right margins for other pages should be 1.5 cm and others 2.5 cm, and the text should be justify to both sides. This guide is a sample file for all these requirements. It is recommended that you hyphenate words to achieve more even word spacing.

Line Spacing
The article’s main text should be single-spaced and fully justified in 12-point Times New Roman font. Do not leave a single line space between paragraphs, and do not indent the first line of a new paragraph. Use a space after punctuation marks such as periods, commas, semicolons, and colons. Do not use spaces after dots in abbreviations (for example, i.e., etc., U.S.).

Titles
For the main headings, 12 point Times New Roman bold font, all letters should be capitalized and centered. Use 12 pt line before the main headings and 18 pt line after the main headings. For second headings, use 12-point Times New Roman font and capitalize the first letter of the first word. For third headings, use 12-point Times New Roman font, and only the first letter of the first word should be capitalized.

Header/Footer
Please do not put headers or footers in your article.

Title Page Information
• Title of the Article
Do not use a separate title page. For the title of the article, use 14-point Times New Roman bold font with only the first letter of each word (excluding the conjunctions) capitalized and centered.
• Authors
Do not write any information about the author(s) at this stage. Author information will be requested after your submission is accepted for publication.
• Abstract
No more than 300 words should be used in the abstract to indicate the nature of the subject and briefly explain the article’s findings. A summary is usually presented separately from the article, so it should be understandable. References should not be used in the abstract. In addition, non-standard or uncommon abbreviations should be avoided. If necessary, they should be defined where they are first mentioned in abstract.
• Keywords
No more than five keywords should be written immediately after the abstract. Only abbreviations that are strictly defined in the related field may be used. Keywords will be used for indexing purposes. Keywords are recommended to be chosen from the Science Terms of Turkey (http://www.bilimterimleri.com).

Article Structure
The body of the article should be separated from the abstract by two-line spaces. The "body text" style used here is a justified 12-point Times New Roman font. Single line spacing (12 points) should be left between paragraphs. The first word of a new paragraph should not be indented.

Footnotes, Figures and Tables
• Footnotes
Footnotes are not recommended, but can be used when necessary. They should be numbered consecutively and placed at the bottom of the page on which they appear, separated from the body of the text by a line 25 mm. A line spacing should separate two footnotes on the same page. Make sure you follow the margin requirements at the bottom of the page. Footnotes should not be added to the equations.
• Figures and Tables
11-point Times New Roman font should be used for figure and table captions. Figures and tables should be placed immediately after the first citation in the text and should be placed so that they can be easily referenced while reading the text.

Figure captions should be placed under the figure, centered and not bold; no dots should be left after the figure number or at the end of the line.

Table headings should be placed at the top of the table, centered and not bold, no dots should be left after the table number or at the end of the line. The first line of the table should include explanations.

For both table and figure captions, only the first letter of the first word should be capitalized unless a word necessarily needs to be capitalized. Bold fonts should not be used. Dots should not be used after table and figure numbers and at the end of lines. Tables should be centered across the entire page if possible. Entries in the cells of the table should be left justified. The font used for cell entries is left to the discretion of the author. In general, it is recommended to minimize the number of vertical lines and use only horizontal lines whenever possible.

In the tables that continue on the next page, the phrase (continue) should be added in parentheses after the table title. Explanations should be included in the first line of the continued tables.

Reference Citations
Please use the IEEE Reference to format your references: https://www.ieee.org/documents/ieeecitationref.pdf

Please align your references to the left and do not use IEEE preferred hanging indents. Books, journals, and other references should be consecutively numbered in the main document text.

Formulas
Please write math equations as editable text, not as images. All formulas should be aligned, and numbered sequentially on separate lines. All symbols must be adequately defined. Identification numbers should be written on the right side of the formula. Simple formulas should be presented in line with standard text whenever possible, and small fractional terms should use a “/” instead of a horizontal line (for example, X/Y).

Supplementary File
If a supplementary file is required in the study, it should follow the article’s main text and come before the references. All accompanying tables and figures should be mentioned in the text. Table and figure numbers presented should be used as “Table S1” and “Figure S1” in the supplementary file.

2. PUBLICATION POLICY
Sakarya University Journal of Science (SAUJS) is an open-access journal that aims to increase the public's visibility and impact of scientific studies and is aware of the need for information to be easily accessible to develop science and strengthen the scientific communication network. Creative Commons Attribution-Non-Commercial 4.0, provided that the source is cited in known standards, all rights of use (online linking, copying, printing, reproduction in any physical medium, distribution, etc.) other than for commercial use and content change (unless otherwise stated in the relevant content). It is made available through its International License (CC BY-NC). Commercial use of the content is prohibited. Articles in the journal can be used as long as the author and original source are cited. No permission is required from the author and publishers.

Six issues are published in SAUJS every year in February, April, June, August, October, and December.

SAUJS does not charge any publication process fee from the author/authors at any stage (submission, evaluation, and publication).

The journal's publisher, Sakarya University Institute of Science and Technology does not charge any publication fee for accessing electronic resources.

2.1. Publication Process of the Journal

• Pre-evaluation process
Articles submitted to SAUJS first fall into the system of the journal secretary. The journal secretary checks whether the files required for the article’s presentation are fully uploaded to the system by the author and whether the file names are appropriate. In addition, it creates the similarity report of the article and uploads it to the system. If there are deficiencies or errors in the files or if the similarity rate of the article is above 30%, the article is sent to the author again to make the necessary updates.

If there is no similarity rate or problems with the files, after this step, the article is sent to the Spelling and Language Editor. The Spelling and Language editor is responsible for checking the compliance of the article with the journal's article writing template and the writing language. After the Spelling and Language Editor has checked, if it has a positive opinion, it sends the article to the Statistics Editor for statistical evaluation of the article. (If there is a problem in the writing style or language of the article, the article is sent back to the author for correction.) After the statistical editor makes the evaluation, the article is directed to the editor related to the field of the article. From here on, the status of the article appears as IN EDITOR. That means the article has been pre-checked.

While in the secretary step, the maximum time given to the secretary for article control is ten days. In this process, the status of the article appears as UNSERVED. When the article is resent to the author, the article’s status will be RE-SEND REQUEST SENT, and the author is given one week to respond to this request. The author who accepts the request has 15 days to resubmit the article. In this process, the article’s status appears as RE-SEND REQUESTED (AT THE AUTHOR). The additional time given to the author(s) who do not return within the specified periods is five days. The maximum time given to the Spelling and Language editor or the Statistics editor is 15 days.

The editor, taking into account the similarity report of the article sent to him, checks whether the article is scientifically sufficient, whether it is a study prepared in line with the purpose and scope of the journal, and its original value. After this check, if it has a positive opinion, the EVALUATION step starts. (If it has a negative opinion, it rejects the article without being included in the referee process.) The editor can also appoint a field editor to do all these checks if necessary.

The maximum time for the editor to take over the article (Check Complete Step) is ten days. The maximum time (Editor Step) for the editor to continue processing the article after taking over is ten days.

• Evaluation process
The editor of the article or the field editor appointed by him, after taking over the article, appoints and invites at least two referees related to the subject of the article to review the article. The reviewer's response time to the invitation to evaluate (accept or reject the evaluation of the article) is seven days. In this process, the status of the article appears as Invitation Sent. The article evaluation form is automatically sent to the referee who accepts the invitation. (In this process, the status of the article appears as Under Evaluation.) The referee's evaluation period for the article is 15 days. Referees who do not return within the specified time are given an additional five days.

In the referee process, the following principles are acted on.

SAUJS operates on the principle of double-blind review. This means that the author(s) of the article will not know the referees’ identities who will evaluate the article, and the referees will not know the identities of the author(s). The aim here is to make an impartial evaluation.

In order to serve this purpose, the author(s) should prepare an article file without revealing their identities. They should remove identifying information, including author names, from filenames. In addition, document properties must be anonymized. For this, all information suggesting the author’s identity in the document should be removed by saying CURRENT PROBLEMS-REVIEW DOCUMENT-DOCUMENT INSPECTOR-AUDITOR from the Microsoft Word FILE menu. To hide the author(s) of the presented work, attention should be paid to the citations made in the article. For example, when the author(s) is citing their work, instead of saying “In our study at [5]…”, “In a study [5] …….” should use the phrase. Author and institution information should not be included in the images in the article. Headers and footers should not contain personal information. When working according to this system, discrimination that may arise from the demographic characteristics or gender of the author is minimized. There is no pressure on the article’s author or the reviewer who examines the article.

The referees who accept the evaluation access the article file via the system (in this process, the referee cannot see the names of the article author(s) on the system). They examine the article within 15 days and upload the completed referee evaluation form to the system.

The number of referee evaluations required for the decision regarding the acceptance or rejection of the article is determined by the editor of the article. The article’s status, which has the desired number of referee evaluation forms, appears as READY FOR DECISION. The time given to take action in this step is seven days. The maximum time allowed for the editor to decide (WAITING FOR DECISION STEP) is seven days.

In this process, the editor has to decide on line with the referee reports. It can also add additional views. The referee notifies the reports and suggestions to the author with a decision letter. With this letter, the article can be accepted or rejected. The editor, if he wishes, may request revisions from the author. The period given to the author to respond to the revision request is seven days. The period given to the author who accepts the revision request is 15 days. (In this process, the article’s status appears as AUTHOR.) After all these steps, accepted articles are transferred to the publication process.

• Publishing process
It is how the accepted articles are prepared for publication in the relevant issue. In this process, the article’s status appears as In Publication Process. In this process, the editor of the publication, the layout writer, and the end reader take part. The layout editor is responsible for making the article ready for publication (such as page layout, placement of tables and images in the article, order of references, page numbers according to the priority of the article acceptance date, placement of the publisher's logo in the article).

The final version of the manuscript, which will be published in the relevant issue, is presented to the users in EARLY VIEW on the journal web page for the author to see. In this process, minor errors that may be present in the article are identified, and there is still time to correct them. If the author detects any errors in this process, he should notify the technical communication officer of the journal by e-mail. The publication editor, who receives information from the technical communication, will make the necessary correction. Articles can wait up to 15 days in EARLY VIEW. It is then published in the relevant issue. After the issue is published, there are ONLY 5 DAYS to correct possible errors. However, the author(s) are expected to submit correction suggestions while the article is in EARLY VIEW.

Article submission/processing is free of charge.
