CATEGORIZATION OF PAPERS

Review form

The author may suggest a category for his/her paper, while the final decision rests with the Editor, upon reviewer’s proposal:
1. Original Scientific Paper – mandatory review
2. Preliminary Communication – mandatory review
3. Review – mandatory expert review
4. Professional Paper – mandatory review
5. Conference Paper
6. Other: Presentations, social news, review from foreign expert references, etc.

Original Scientific Paper
contains unpublished results of original research, while it has to be written in a manner permitting for the experiment to be repeated based on the information provided, achieving the same described results with the same accuracy, or within the limits of experimental error, as stated by the author; repeating the author’s observations, calculated or theorical outcome and coming up with the same conclusions.

Preliminary Communication
contains yet unpublished preliminary scientific research results, the character of which requires urgent publication. The paper does not have to contain sufficient details enabling repeating and checkup of stated results.

Review
is a concise, critical review of a specific research area (field), providing fresh information on the existing condition of development and orientations.

Professional Paper
constitutes useful contributions from the industry’s field, the content of which is not associated with original research. It provides a critical review of the chosen subject, including both orientations and controversies. It must be understandable even to those not specialized in the field in question. It differs from the scientific paper primarily in the sense that it does not provide original results of the author’s research, but rather uses the already published results which it then systemizes and explains.

Conference Paper
The category includes papers which cannot be categorized in any of the above categories, while it has been presented at a scientific gathering and does not feature in the related collection of papers.
