International Visibility of Bulgarian Memory Research

Contemporary neuroscience is characterized by intensive internationalization of basic and applied memory research. A scientometric analysis of the publications by Bulgarian authirs abstracted in MEDLINE from 1966 till 2004 was carried. A total of 94 papers authored by 61 Bulgarian authors and published between 1980 and 2004 became internationally 'visible' through this widely used data-base. Four Bulgarian journals contain 38 articles but 25 foreign ones from 10 countries - 56 articles. A total of 50 papers were published in 22 mono-disciplinary journals from 11 countries, 36 - in 4 two-disciplinary journals from 4 countries, and 7 - in 2 journals from two countries. In 11 journals containing the term 'pharmacology' in their title a total of 65 papers by Bulgarian authors were published. Acta Physiologica et Pharmacologica Bulgarica (Bulgaria) contained 32, Methods and Findings in Experimental and Clinical Phamracology (Spain) - 15 and European Neuropsychopharmacology - 5 papers. International collaboration resulted in 5 papers published in Bulgarian and in 12 papers published in foreign journals. V. D. Petkov and V. V. Petkov from the Institute of Physiology of the Bulgarian Academy of Sciences (Sofia) were the most productive authors in this field with 36 and 30 papers, respectively. Recently, there is a trend of gradually improving international visibility of Bulgarian pharmacology dealing with memory in man and animals

INTERNATIONALIZATION OF CLINICAL AND EXPERIMENTAL MEMORY RESEARCH

A problem-oriented retrospective information search in MEDLINE on CD-ROM in 1981-1993 revealed the relevant publications devoted mainly to physiology and pharmacology of human and animal memory. The annual dynamics of a set of bibliometric parameters (number of articles and journals containing these articles; number of countries of authors and journals; number of publications in own and foreign journals; number of interdisciplinary and international journals, language of papers, etc.) was studied to identify some essential patterns of internationalization of the interdisciplinary memory research. There were a total of 5597 papers by authors from 48 countries in 809 journals from 40 countries. In 1988-1993 only, there were 1361 papers (48,47 %) in foreign journals. In 42 international journals from 9 countries a total of 231 papers were published while 50 interdisciplinary journals from 13 countries contained 579 papers. Bulgarian memory research was relatively insufficiently presented in this data-base

International visibility of Rhinoplasty research

Rhinoplasty represents a widely used surgical approach to correct nasal deformities and imperfections. A scientometric investigation of the world publication output and citations on these problems was carried out in Web of Science (WoS), MEDLINE, and EMBASE for a 26-year period - from January 1985 till December 2010. Any relevant publications which had been abstracted were retrieved and analyzed. In this narrow field, 4155 publications were abstracted in MEDLINE (WoK), 2286 - in EMBASE, and 1980 - in WoS. English-language publications amounted to 1922 in EMBASE and to 1895 in WoS. There were more than 7700 author's names with papers on rhinoplasty abstracted in MEDLINE (WoK) and more than 3500 ones - in WoS. The most productive authors, institutions and countries as well as the 'core' journals were identified. Bulgaria has become internationally visible with 3 papers abstracted in WoS, with two - in EMBASE, and with one - in MEDLINE (WoK). The intensity of collaboration between the researchers within the single scientific unit, between different scientific institutions in one and the same city, in different cities of one and the same country, and between collectives from different countries permanently increased. A broader incorporation of Bulgarian scientists into the international scientific communities should be recommended.Scripta Scientifica Medica 2011;43(2): 101-10

HISTORIOGRAPHY OF SCIENTIFIC COMMUNICATIONS IN THE FIELD OF MEMORY AND BLOOD-BRAIN BARRIER

A scientometric study after author's own methods (Tomov, 1986 and 1998) of the publication output in the field ofmemory and blood-brain barrier in MEDLINE on CD-ROM (EBSCO Publ., USA) data base for 1965-2000 was carried out. On this interdisciplinary topic, a total of 126 articles in seven languages, mainly in English, had been published in a total of 93 journals from 21 countries. In 37 review articles there were 5289 references (at an average of 143 references per paper). Authors' institutions belonged to 18 mono- and 7 interdisciplinary thematic profiles while the journals could be assigned to 17 mono- and 8 interdisciplinary profiles. Some 39 journals from 12 countries containing 57 articles belonged to the generalized profile of neurosciences. The authors from the USA had published 37 papers in 30 American journals but 16 ones in 10 journals from 5 countries. Aa a whole, 67 papers had been published in domestic journals but 59 ones in foreign journals. Eight articles by authors from 6 countries had been published in 7 "international" journals from 5 countries. The computerized historiography of science could be successfully applied for scientometric purposes and for perfection of science policy and management at any levels in small countries like Bulgaria
