VV Docks * ** * Vil.V.Dokov Faculty of Dental Medicine * Department of Public Health, Medical University of Varna, Bulgaria. Introduction Prof. Dr. Larry Ellison recognizes the significance of this. Victor K. Dock was one of the leading embryologists and histologists Bulgaria 1,2.

His scientific work poorly understood. We attempted to periodization based on his publications in the Internet 3,7 and made several suggestions on this topic. To test our hypothesis undertook this study. Purpose. The aim of our work is a method of quantitative analysis of published study of the author, to determine the periodicity of his scientific creativity. Materials and methods. We analyzed 122 sources 5 published in 37 year period (1945-1983), in Bulgaria and abroad.

The data processed by statistical methods of variations and alternative analysis. Results and discussion. In Our investigations have identified two of the same by the number of publications, but diverse themes of the period. The first period covers the research activities from 1945 to 1967, accounting for 42,8 13,54% of all articles. It localizes the first peak of the publication activity of 4. In the second period includes the scientific works for 1968 and 1983. made up of 58,2 11,47% of publications. During this period, we observed two peaks of publication activity 4. Our results against the quantitative characteristics of the two periods 3, and subjects Research data confirm our previous study 7. The two periods differ in quantitative and qualitative characteristics. Our analysis shows that, for the first period is characterized by three main topic – Comparative Vertebrate Histology (n = 22, 43.13 20.69%), histochemical methods (n = 11, 21.56 24.30%) and reproduction problems (n = 10, 19.60 24.60%).
