Kocaeli Journal of Science and Engineering (KOJOSE) publishes research and review papers written in English.

The research paper is an article reflecting the findings and results of original research, while the review paper is an article compiling an adequate number of articles, summarizing the present level of science or technology, and making an evaluation as well as a comparison of the findings of these articles.

Manuscripts should be submitted by one of the authors through the online submission system. The submitting (corresponding) author is responsible for the manuscript during submission and peer review processes.

The names of all authors should be entered into the system during the first submission. The names, ORCID numbers, and affiliations of all authors should also be indicated on the first page of the submitted manuscript.

All submissions should be accompanied by The Copyright Transfer Form containing the names of all authors and signed by the corresponding author.

Ethics approval is needed for studies on vulnerable populations, policies, confidential data, ethical business/marketing practices, clinical researches on human subjects, researches using animals, and retrospective subjects. Ethics committee approval should be stated together with the board name, date, and number in both the “Method” section of the manuscript as well as its last page. When submitting the manuscript, the Ethics Committee Approval file must also be uploaded onto the system.

Written permission must be obtained from the owners of other Copyright holders for the use of their materials such as photographs, figures, tables, etc.

All manuscripts submitted to KOJOSE are first assessed by the Editor to find out their suitability for the Journal. Suitable manuscripts are then scanned by the similarity software as described in the Anti-Plagiarism Policy section of the journal website. Appropriate manuscripts are sent to at least two expert reviewers to assess the scientific level of the paper. KOJOSE adopts a single-blind review system in which the reviewers’ identities remain anonymous to the authors. Manuscripts are expected to meet certain standards of scientific excellence to get published in the Journal.

Declaration of Ethical Standards: If the study does not require Ethics Approval, the following declaration can be used:

“The author(s) of this article declares that the materials and methods used in this study do not require ethical committee permission and/or legal-special permission.”
Otherwise, please declare the board name granting ethics approval, approval date, and approval number.


16) Tables should have consecutive numbers and captions at the top in accordance with their appearance in the text.


17) Figures should have consecutive numbers and captions at the bottom in accordance with their appearance in the text. Size the illustrations close to the desired dimensions of the printed version. Please make sure that artwork files are in an acceptable format (TIFF or JPEG) and with the correct resolution (min. 300 dpi).


18) Captions should be justified left and ride sides of the figure or table. Locate the tables and figures close to the paragraph in which they are mentioned first. If one column is not wide enough for a table or figure, you can merge the columns as shown in the template


19) The text should have a citation of each figure and table. Letters in the figures should be large enough to be readily seen.


20) Abbreviations should be defined where they first appear in the text. The title of the paper should not have any abbreviation.
