Bibliography List Research Articles

The scientific heritage of Dimitriy Dan and his printed works bibliographical index (1875–1927)

The article is another step in the research of the scientific creativity of Bukovyna priest, historian, ethnologist, corresponding member of the Romanian Academy of Sciences Dimitriy Dan (1856–1927). The fact of international recognition of his works is undeniable, not to mention the use of his creative heritage in Ukrainian and Romanian historiography. But, unfortunately, today there are no special bibliographic studies, a complete list of printed scientific and scientific journalistic works of the tireless scientist. Therefore, the purpose of this study is to compile a bibliographic index of D. Dan's printed works on the basis of source materials. Since this topic is new in modern scientific circulation, in connection with the indisputable actualization of D. Dan's personality and creativity recently, we consider it timely and relevant. It is necessary to state the fact that there is currently no complete list of D. Dan's printed works. The scientist's scientific works (books, articles, including partial bibliographic lists of his works) are scattered on the pages of various journals, magazines and books, directories located in libraries and museum institutions of Ukraine, Romania, Austria and other European countries. Conclusions. The purpose of the research, namely, compilation of the bibliographic index of D. Dan's printed works, was achieved by: 1. Detailed study of previous attempts to compile partial bibliographic lists (D. Dan's letter to the Romanian researcher A. Horovei (1898), L. Bodnerescu's bibliographic work "Romanian Authors of Bukovyna. Repertory" (1903); D. Dan's book is dedicated to the study of the role of Bukovyna clergy in the preservation of Romanianism (1925); 2. Research of the periodical press of that time: the leading Austrian and Romanian magazines on history and ethnology ("Zeitschrift fur osterreichische Volkskunde" (Wien), "Familia" (Buda-Pesta), "Analele academiei Romane", "Buletinul Comisiunii Monumentelor Istorice" (București), "Ion Creangă", "Făt-Frumos" (Bvrlad), "Arhiva Genealogică " (Iași), "Şezătoarea" (Fălticeni), Bukovina newspapers and magazines: "Bukowinaer Nachrichten", "Bukow. Rundschau", "Cernowitzer Allgemeine Zeitung", "Gazeta Bucovinei", "Glasul Bucovinei", "Junimea Literară", etc. .; 3. Study of the main books and brochures of the scientist, which are kept in libraries and funds of museum institutions, archives, libraries of Chernivtsi (Ukraine), Suceava (Romania). An important factor in the effective finding of the necessary facts was the use of special information and search systems on the Internet, which allowed the use of online archives of Austrian, German and Bukovina magazines and newspapers. The conducted research made it possible to restore the full titles of the scientist's printed works, the years of publication, bibliographic data on magazines and newspapers in which D. Dan's works were printed. The bibliographic index of the printed works of D. Dan (1875–1927) is printed for the first time in the appendices – 154 items; handwritten materials (9 items); republished works of the scientist after his death (4 items). The titles of all D. Dan's works have been translated into Ukrainian.

Meta-analysis of Long-term De Novo Acid Reflux-Related Outcomes Following Sleeve Gastrectomy: Evidence Against the Need for Routine Postoperative Endoscopic Surveillance.

To evaluate the incidence of long-term de novo acid reflux-related complications following sleeve gastrectomy (SG) to determine whether routine postoperative surveillance endoscopy is necessary. A systematic search of Medline, Embase, CINAHL, CENTRAL, the Web of Science, and bibliographic reference lists was conducted. A proportion meta-analysis model was constructed to quantify the risk of the de novo gastro-oesophageal reflux disease (GORD), oesophagitis, and Barrett's oesophagus (BE) at least 4years after SG. Random-effects modelling was applied to calculate pooled outcome data. Thirty-two observational studies were included reporting a total of 7904 patients who underwent primary SG and were followed up for at least 4years. The median follow-up period was 60months (48-132). Preoperative acid-reflux symptoms existed in 19.1% ± 15.1% of the patients. The risk of development of de novo GORD, oesophagitis, and BE after SG was 24.8% (95% CI 18.6-31.0%), 27.9% (95% CI 17.7-38.1%), and 6.7% (95% CI 3.7-9.7%), respectively. The between-study heterogeneity was significant in all outcome syntheses. It was suspected that several of the included studies have not reported BE and oesophagitis because such events might not have happened in their cohorts. Long-term risk of de novo GORD after SG seems to be comparable with those of the general population which questions the merit of surveillance endoscopy after SG in asymptomatic patients. De novo BE and oesophagitis after SG have not been reported by most of the available studies which may lead to overestimation of the rates of both outcomes in any evidence synthesis. We recommend endoscopic surveillance for symptomatic patients only.

Preoperative C-Reactive Protein-to-Albumin Ratio and Its Ability to Predict Outcomes of Pancreatic Cancer Resection: A Systematic Review.

To evaluate the ability of the c-reactive protein-to-albumin ratio (CAR) in predicting outcomes in patients undergoing pancreatic cancer resection. A systematic search of electronic information sources and bibliographic reference lists was conducted. Survival outcomes and perioperative morbidity were the evaluated outcome parameters. Eight studies reporting a total of 1056 patients undergoing pancreatic cancer resection were identified. The median cut-off value for CAR was 0.05 (range 0.0003-0.54). Using multivariate analysis, all studies demonstrated that a higher CAR value was an independent and significant predictor of poor overall survival in patients undergoing pancreatic cancer resection. The estimated hazard ratio (HR) ranged from 1.4 to 3.6. Although there was a positive correlation between the reported cut-off values for CAR and HRs for overall survival, it was weak and non-significant (r = 0.36, n = 6, p = 0.480). There was significant between-study heterogeneity. Preoperative CAR value seems to be an important prognostic score in predicting survival outcomes in patients undergoing pancreatic cancer resection. However, the current evidence does not allow the determination of an optimal cut-off value for CAR, considering the heterogeneous reporting of cut-off values by the available studies and the lack of knowledge of their sensitivity and specificity. Future research is required.

БИБЛИОГРАФИЈЕ АУТОРСКИХ ПРИЛОГА ИЗ ПЕРИОДИЧНИХ ПУБЛИКАЦИЈА: КА ЛИСТОЛОШКОМ ПРИСТУПУ

On the example of two different bibliographic approaches to listed authors articles from periodical publications, in our research we indicate the applicability of the listological approach to this material. In the introduction, we provide insights into the continuity of interest in bibliography in the Serbian scientific tradition, with reviews of its history and theory, from the beginnings in Orfelins Calendar for 1766. and the Slavo-Serbian Magazine (1768), which were on the border between theoretical and critical thinking about literary works and their bibliographic listing. We also refer to previous theoretical approaches to bibliography in Serbian literary science, and shows that they did not give special attention to the question of its reception. After a brief review of the basic theses of listology (theory of list), in the last segment of the research we analyze the possibilities of applying the listological method to bibliographic lists of authors articles in periodical publications.

The bibliographical lists of printed publications from the post-Soviet Russian Book Chamber and about it are submitted. The peculiarities of its production, scientific, instruction and methodical activities in the spheres of bibliography, statistics and bibliology are reflected for the period of 1992–2021.

Maria Mazankówna-Friedbergowa (1900–1993) – zapomniana specjalistka od bibliografii historii polskiej

Maria Eleonora Mazankówna-Friedbergowa (1900-1993) is one of the outstanding bibliographers of the interwar period, and she specialized in the field of Polish history. Together with Kazimierz Tyszkowski, she compiled the Bibliography of History of Poland covering 1926-1928. After she left Lviv for Krakow, she took over the editorial office of the publishing house. She published bibliographic lists for 1929-1934 that were highly appreciated by the scientific community. The outbreak of World War II prevented the publication of the materials collected by Mazankówna-Friedbergowa for 1935-1939. This later appeared in print in 1976, and again in 1981. She rejected the proposal to participate in the work on the republishing of the Bibliography of History of Poland due to numerous errors and shortcomings made by the incumbent editor Karol Maleczyński.

Referencing behaviours across disciplines: publication types and common metadata for defining bibliographic references

In this work, we investigate existing citation practices by analysing a huge set of articles published in journals to measure which metadata are used across the various scholarly disciplines, independently from the particular citation style adopted, for defining bibliographic reference. We selected the most cited journals in each of the 27 subject areas listed in the SCImago Journal Rank in the 2015–2017 triennium according to the SCImago total cites ranking. Each journal in the sample was represented by five articles (in PDF format) published in the most recent issue published in October 2019, for a total of 729 articles. We extracted all 34,140 bibliographic references in the bibliographic references lists of these articles. Finally, we detected the types of cited works in each discipline and the structure of bibliographic references and in-text reference pointers for each type of cited work. By analysing the data gathered, we observed that the bibliographic references in our sample referenced 36 different types of cited works. Such a considerable variety of publications revealed the existence of particular citing behaviours in scientific articles that varied from subject area to subject area.

Exploring the Keyword Network Analysis and Research Trends for Sustainable Development of Paralympic Research: Based on Changes in Classification

This study aims to identify an overall keyword network by drawing on core keywords in Paralympic studies and analyzing the relationships. It also aims to provide information on the changes in Paralympic study trends through a time series analysis to understand change, according to the application of a new classification (evidence-based classification). This study made a bibliographic list of 1613 studies by collecting studies published between 2003 and 2022 using keyword network analysis (KNA). By refining to exclude unsuitable studies, 1404 studies and 6414 keywords were used for the analysis. As a result of analyzing entire Paralympic studies performed between 2003 and 2022, Paralympic studies were revealed to be on the rise. The entire Paralympic studies ascertained that the areas of study were mainstream and centered on the top three keywords: athlete; performance; and classification. Secondly, as a result of analyzing Paralympic study trends in a time series manner, based on 2017 when a new classification was applied, studies related to physical impairment centered on the top two keywords, athlete and performance, were mainstream in Section 1 (2003–2016). Olympic Games, performance, and wheelchairs formed detailed study areas. In the Paralympic studies in Section 2 (2017–2022), the relevant studies centered on the top two keywords, athletes and performance, were mainstream. Parasport, disability, and classification were ascertained to form detailed study areas. Through all this, the changed trend in the keyword Paralympics was confirmed. The results of this study are meaningful in that they can contribute to the expansion of the Paralympic areas of study and invigoration by exploring core keywords and providing relevant information based on the significant change point in time, including entire Paralympic study trends.

Effectiveness and safety of Inclisiran in hyperlipidemia treatment: An overview of systematic reviews.

This paper aimed to comprehensively evaluate the effectiveness and safety of Inclisiran in treating hyperlipidemia through an overview of systematic reviews (SRs). The Cochrane Library, EMBASE, PubMed, CNKI, WANGFANG database, VIP database, ClinicalTrials.gov, and ICRT were searched electronically to collect SRs and meta-analysis of Inclisiran in hyperlipidemia treatment from the establishment of the database till May 2022. Two researchers independently screened the relevant literature, then the assessment of multiple systematic reviews tool was made into assess the methodological quality of the included studies. Data extracted were used to perform the study through RevMan5.3 software. The grading of recommendations assessment, development, and evaluation tool was used to grade the quality of the evidence of the outcomes included in the SRs. Prospero ID: CRD 42022326845. A total of 10 relevant SRs were included, involving 7 randomized controlled trials. The assessment results of the assessment of multiple systematic reviews tool suggested that the quality of the SRs included needed to be improved. The reduced level of low-density lipoprotein cholesterol of the experimental group was lower than the control group, and the difference in the amount of effectiveness was statistically significant (MD = -50.13, 95%CI: -56.2 to -44.06, P < .00001). The grading of recommendations assessment, development, and evaluation results showed that out of 27 outcomes, 8 were high-quality, 3 were of medium quality, 6 were of low quality, and 10 were of the most inferior quality. 300mg Inclisiran with 2 injections a year has the best therapeutic effect, which can significantly reduce low-density lipoprotein cholesterol and total cholesterol, and increase high-density lipoprotein cholesterol levels in patients with hyperlipidemia. Inclisiran has a favorable safety profile, with no significant difference in the incidence of adverse reactions compared to a placebo. Most of the adverse effects were associated with the reaction on the injection site.

Сибирская ученица «школы читателей Ахматовой»

A totally forgotten feuilleton placed in Tomsk newspaper in 1916 is reproduced with a historical commentary. It belonged to a pen of art expert Tatiana Sapozhnikova-Chernavina (1887– 1971) and was never mentioned in any of numerous bibliographic lists on Anna Akhmatova’s creative works. She is known as brave fugitive female for her heroic escapade from USSR in 1932 together with her husband, a prominent fishery biologist, and little son. Her early works as a literary observer are worth to be included in contemporary circularization (e.g. an essay on Ilya Ehrenburg’s poetry et al.). The article “Modern Poetesses: Anna Akmatova” was an attempt to reconstruct the net of motifs spanning the poems of the book “Rosary” (1914). The foreword to the annotated republication points some relevant patterns of the literary attitude of Sapozhnikova-Chernavina as well as lists some of the main milestones of her biography including the episodes when she is represented as an eyewitness of swiftpassing but meaningful tragic moments in the history of Russian poetry under Soviets. A question is raised about picking up her scattered literary heritage.

ChatGPT в исследовательской работе студентов: запрещать или обучать?

Importance. ChatGPT, developed on the basis of artificial intelligence technologies, is able to significantly change the scientific research activity of scientists and students, performing for them some routine work on searching and processing literary sources and other data, as well as compiling research texts. At the same time, the integration of ChatGPT into education and science causes heated discussions in the academic environment. The purpose of the research is a) to review studies on the use of chatbots in general and ChatGPT in particular in research work, b) to conduct an empirical study to test the ability of ChatGPT to compose research texts and describe the results of the analysis of the data obtained; c) to identify and discuss key issues related to the effectiveness of using ChatGPT in students’ research work. Materials and methods. The empirical study was conducted at Derzhavin Tambov State University and included interaction with ChatGPT in order to compile on its basis fragments of research work consisting of the relevance of the topic, a literature review (definitions of concepts and positions known in a particular field of knowledge), analysis of search results, selection of bibliography. The experimental work was carried out on the material of the methods of teaching foreign languages. Results and Discussion. ChatGPT has proven its worth in solving only a few research tasks in accordance with user requests (to formulate the relevance of the work, to give definitions of concepts proposed by different authors and descriptions of established constructs, to analyze and summarize data results, to generate new data, to compile a bibliographic list). The volume of reviews and the depth of their content turned out to be of more satisfactory and unsatisfactory quality. In addition, in cases of lack of the necessary information to solve the task, ChatGPT resorted to falsifying data and generating non-existent information. Conclusion. Based on the analysis of search query data, the authors identify a list of key issues and problems, the solution of which will contribute to a more effective use of ChatGPT in the research work of young scientists and students. Such issues include the following: a) the quality of the materials provided by ChatGPT at the user’s request; b) the availability of ChatGPT and other analog programs; c) the ability and capabilities of ChatGPT to provide certain materials and perform some analytical functions; d) the contextuality of a series of requests; e) the combination of traditional intellectual work of a person with work based on ChatGPT; f) the author’s ethics of writing research texts; g) the inability of ChatGPT to adapt the results of search queries to the user’s level of language proficiency; h) the educational aspect of creating ChatGPT research texts; i) the price of the question (or to what time and labor-intensive costs lead the using of ChatGPT in research work); j) the competence of the user in the professional field when using ChatGPT.

Z polskiej leksykografii biograficznej, nekrologicznej i komemoratywnej. Rosja i ZSRS a Polska – ofiary antycywilizacji. (Bibliografia prac z lat 1832–2021 – w wyborze)

From Polish biographical, obituary and commemorative lexicography. Russia and the USSR versus Poland – victims of anti-civilization. (A bibliography of selected works from 1832-2021) The paper presents selected issues in the area of Polish biographical lexicography from the genological perspective. The author proposes to distinguish a new type – obituary and commemorative lexicography. She states that no monographic work on biographical lexicography has been published within the Polish scholarly society. The existing publications are only in the form of thematic/problem and review articles. The second part of the paper contains a list of 379 Polish dictionaries; the bibliography covers the years 1832–2021. The data presented are considered statistically important. The bibliographic list includes various types/forms of dictionaries – strictly biographical dictionaries, lexicons, encyclopedias, dictionary-encyclopedias, encyclopedic guides, reference books (e.g. Who is who?), directories of people (e.g. The Book of Siberians), personal loss books, cemetery books, lists of people, alphabetical lists of people, lists of surnames, nicknames, registers of the dead, deported and others, indexes of people (e.g. of repressed people) and others, inventories (e.g. names of labor camps), etc. Formally, publications of this type meet the requirements of studies in the field of lexicography because: 1/ they constitute a linearly ordered set (by lexicographic order), and 2/ they are specific databases storing specific information.

Bibliographic Index of the Contents of the Journal “Bibliotekovedenie”. To the 70th Anniversary of the Periodical

In 2022, the Publishing House “Pashkov Dom” of the Russian State Library released the bibliographic work “Journal ‘Bibliotekovedenie’: Index of Contents 1952—2021”. The publication was prepared by the Research Department of Bibliography of the Russian State Library for the 70th anniversary of the scientific and practical journal. The article briefly describes all the milestones of the leading professional publication: from the periodical scientific collection “Libraries of the USSR. Work experience” up to the contemporary journal “Bibliotekovedenie”. Materials of the periodical have significant scientific value. The compilers of the bibliographic index ordered and systematized publications, as well as characterized previous similar works — cumulative in-journal indexes of contents and the only index of 1984 until 2022 published by the V.I. Lenin State Library of the USSR. The author highlights the number of differences between the previous indexes dedicated to the journal and the 2022 edition, among them are the completeness of coverage of the material, the structure and methodology of systematization, the availability of reference apparatus, etc. The reference apparatus of the new edition consists of five auxiliary indexes (index of names, personalia, library and information organizations, peer-reviewed publications and library and information serials). The book includes four reference appendices (the list of editors-in-chief, members of the editorial board and the editorial council; bibliographic list of publications about the journal in the professional press; the list of acronyms of library and information organizations; the list of bibliographic sources). In the process of compiling the index, the compilers encountered difficulties at the stage of grouping the material. Over the entire period of the journal existence, publishing standards and drawing up of the publication have changed many times. The compilers executed the painstaking work to identify the authorship of individual publications, as well as the identity in the names of repeatedly renamed library and information organizations, and to reveal data on the personalia mentioned in the articles. The article gives the examples of drawing up of the index. The index of publications of the main professional periodical from 1952 to 2021 reflects the processes of development of science, evolution, transformation of scientific knowledge and makes the basis for the work of researchers at present, being the significant mechanism of scientific activity.

Levko Bykovskyi’s Training Concept of Library Specialists

Problem statement. Modern Ukrainian society is changing as a result of irreversible demographic, intellectual and cultural losses. The tasks of reconstruction and development of the country cause new challenges for the educational, scientific and industrial sectors. Resistance to Russian expansion requires innovations in information activities too. The transformation of the public role of library institutions is observed. There is a need to transform libraries into modern socio-cultural institutions that fully meet today’s requirements of a society. The key to successful changes in the library industry is the improvement of its staffing and effective innovative management. This, in turn, requires a thorough analysis of the national and global experience of librarians.&#x0D; The purpose of the research is to study the curricula on book studies, bibliography and librarianship, which were used in Librarianship higher course for librarians at the Warsaw Public Library.&#x0D; The methodology of this study is based on a complex approach, that combines both general scientific and problem-specific methods. Among them there are methods of systematization, data processing, terminological analysis, generalization, as well as logical, descriptive, historical-genetic, and retrospective ones.&#x0D; The results. The curricula on book studies, bibliography and librarianship, used in Librarianship higher course for librarians at the Warsaw Public Library, are concluded according to a single principle. Each course contains a curriculum and a thorough list of literary sources, as well as methodological recommendations on the scientific organization of work, ergonomics, etc. The curricula are divided into content modules and thematic blocks. The authors assume that mastering the proposed curricula was a sufficient basis for the successful professional implementation of the course graduate.&#x0D; The scientific novelty of the study lies in a comprehensive study of the dynamics of the library field development and the librarians training experience with the aim of borrowing the best elements of it into the modern educational process and abandoning unsuccessful methods.&#x0D; The practical significance lies in the attempt to focus attention on the training curricula for librarians at the Warsaw Public Library, developed by scientists of the Ukrainian diaspora, who in the period of the 20-30s of the XX century were the leaders of the library industry, since in the Soviet Union bibliography, like a number of similar educational courses, were in decline.&#x0D; Conclusions. The analyzed brochure, despite its small volume, is quite informative. Its author emphasizes the need to write a textbook on library science and at the same time points out its practical significance for the scientific studies of graduate students, the effective work of librarians and their managers. In addition to the idea of librarians at that time, the brochure indirectly gives us information about the life and activities of Ukrainians in emigration, as well as the level of development of the centers of Ukrainianism, in particular in the city of Kalisz, illustrates the relations between the scientific communities of the Ukrainian diaspora and post-Soviet Ukraine. Any scientific papers containing extensive bibliographic lists serve as reference points for scientific research activities since, unfortunately, library funds suffer irreversible losses after the horrors of war.

BOOK EXCHANGE FUND OF THE SCIENTIFIC LIBRARY AS A BUSINESS CARD OF THE UNIVERSITY

Forming, accumulating, as well as bookkeeping of documentary resources is one of the traditional functions of a modern library. Library book collections are of exceptional importance for the formation of the national cultural heritage of the state. The Book Exchange Fund (hereinafter – BEF) of the Scientific Library of the Odesa I. I. Mechnikov National University is a part of its Exchange and Reserve Fund. The department is intended for exchange, redistribution, free transfer of documents to libraries and other institutions. BEFs in libraries acquired a legal status in 1959 when a special resolution of the Soviet government was adopted. The documents began to be redistributed through an Exchange and Reserve Fund, which contributed to the preservation of non-core and duplicate editions in some libraries that could be in demand in other libraries. The mechanism for using documents that are in library exchange funds is defined by The procedure for using documents through exchange library funds. In 1947, a BEF for monographic literature was arranged while a BEF for periodicals was allocated. Nowadays the BEF consists mainly of duplicate editions of the University. These are publications highlighting the history of Odesa National University, the works of the teaching staff of the Humanities and Natural Sciences faculties, as well as publications prepared by the Scientific Library staff. The activities of the Department of Rare books are aimed at researching private collections of the Library. Special attention is paid to the research of Ukrainian books from the stackss of the Scientific Library. Employees of the Information and Bibliographic Department publish bibliographic indexes, both thematic and devoted to personalities. It is worth mentioning that the Scientific library exchanges specialized periodicals with partner libraries. The Library has 17 permanent book exchange partners, namely the higher educational institutions, research institutes, the National V. I. Vernadskyi Library of Ukraine. Since 2020 alone, the Library has received through book exchange 860 copies of books and periodicals and sent to its partner libraries 694 copies of current professional University periodicals. This method of periodicals distribution contributes to the popularization of the academic achievements of scientists of the Odesa I. I. Mechnikov National University in the professional community. The content of the BEF is disclosed with the help of a reference apparatus, that is card catalogues and non-annotated bibliographic lists of books and periodicals, posted on the website of the University Library in the section Exchange and Reserve Fund (Book Exchange Fund). The Book Exchange Fund is separated from the main stacks, it is not inventoried and is not used for reader service. The work with the Exchange and Reserve Fund of the Library is ongoing. The Book Acquisition Department is carrying out organization and distribution the documents which come to the BEF, improving the accounting of documents. The Department staff continues processing the reserve part of the Exchange and Reserve Fund selecting copies to replenish the main fund of the Library and removing physically worn copies.
