a) Title of the paper
The title should be informative and short with maximum length of 100 characters or 15 words. Never in capitals or boldface, not centered, font 14 cpi.
b) Author(s)
Provide full names (first and family name) of all authors and indicate the corresponding autor. Font 13 cpi.
c) Authors’s address
The name and address of institutions of research origin, e-mail of the first author, 10 cpi.
d) Abstract
The Abstract should be provide a brief summary (no more than 250 words) of the study including the purpose, methods, results, and major conclusions. Font 10 cpi, spacing 1.0.
e) Key words
One line, separated by a comma, 10 cpi.
f) Text
Tables and figures (graphs, drawing, photos) – only black-and-white and should be numbered with Arabic numerals in the order or appearance in the text (e.g. Table 1; Figure 1; Figures 3–4), font 11 cpi. Electronic artwork should be submitted as vector graphics (e.g. line artwork) in Encapsulated Postscript Format (EPS) or in MS Excel File Format (XLS), and bitmap files (e.g. half-tones) in Targged Image File Format (TIFF). The journal editor may request to redraw the figure and export it again. If there is a large table it is allowed to use the font 10 cpi. If a table is very large attention should be turned that it have to fit on a page – vertically or horizontally. Table and figure size (with headings and legends) must not exceed 13.5 x 20 cm (because they must fit on B5 page). Tables and figures with their headings and legends should be on separate sheets. The preferred position of tables and figures should be indicated in the margin of the text. Footnotes should not be used. The number of the table and figure should be written above the table or figure. A horizontal line should be drawn above and below the column headings and at the bottom of the table. No vertical lines in the table. Use TAB and not space bar between columns.
g) References
References in the text. Citations in the text should be by author and year: (Coock, 1994; Smith & Trace, 1999). When a publication with more than two authors is cited, only the first is named in the text (Jones et al., 1987). The results of recent work by Smith et al. (1992).... If there is more than one work by the same author or team of authors in the same year, a, b, c, etc. is added to the year both in the text (Smith & Trace, 1999a; Smith & Trace, 1999b) and in the list of references.

Reference list. The reference list should be in alphabetical order according to the first author`s name. authors. All authors and full title of the article should be cited. Journal titles should be given in full. Publications by two authors with the same first author should be listed alphabetically according to the second author`s name. Publications by three or more authors with the same first author should be listed chronologically.
