With the development of the Internet and information technologies, new communication tools have been created that allow researchers to present their research results and communicate with each other. Using visual and audio resources to share research results is a new type of scholarly communication essential for disseminating knowledge and has recently been the focus of journals. Our objective was to help authors, journal editors, and publishers become familiar with the criteria they should consider when producing standard video abstracts. This descriptive study used content analysis. We systematically searched the Web of Science Core Collection and Scopus to identify journals with video abstracts and analyzed their authors’ guidelines to extract the criteria needed for producing and evaluating video abstracts. The research community comprised 209 journals with video abstracts. After reviewing their authors' guidelines, we found that only 90 journals mentioned video abstracts in their authors’ guidelines. Of 90 journals, 22 dedicated authors’ guidelines and 68 journals belong to nine different publishers. Therefore, 31 authors’ guidelines were examined in this study using MAXQDA 12. We identified six main categories, six subcategories, and 87 criteria for producing and evaluating video abstracts. The six main categories included the type of video, technical features, provider features, presentation features, legal aspects, and criteria for publishing and sending video abstracts. Most criteria were related to the technical characteristics of video abstracts, and the least number of criteria were related to attention to legal aspects during the production and evaluation of these abstracts. The scientific community now uses video abstracts as a complementary medium to articles. Researchers can use this type of abstract to share their research results with others. Authors and journals should pay attention to the production criteria when planning to use this type of abstract so that by preparing a suitable video abstract, they can more effectively convey the results of their research to the audience and lead to the promotion of science.

Objective: The disabled like others, need information and information acquisition skills to play a positive role in society. By providing a variety of resources and information services, the public library has an important role in providing services to the community, including the disabled, and can provide the background and opportunity for the presence of the disabled in society. The purpose of this study is to identify the requirements and characteristics of a disability-friendly public library. Methodology: The study was a descriptive applied study using a content analysis method and systematic search, to identify the requirements of public libraries to provide services to the disabled, in Web of Science, Scopus, Google Scholar, and PubMed. From the search in 4 databases, 738 documents were retrieved. Initially, all bibliographic information of articles and sources found from four databases were examined, extracted, and entered into EndNote X7 software, and duplicates were removed. In the next step, the titles of the remaining articles were examined. After reading the abstract of the remaining articles, if the article was deemed appropriate, their full text was studied. Finally, 40 documents were examined. Findings: The indicators and requirements used in public libraries in providing services to the disabled were divided into seven categories. In the category of policy and budget, the existence of appropriate policies and guidelines in the library to provide services to the disabled, in the category of advertising and development of services, the use of various methods of informing library services, in the category of accessibility and physical condition of the library, Existence of appropriate signs and boards to guide different sections of the library, in the category of services and programs, placing the safe desk in a suitable place and its availability for all groups, in the category of human resources and training, the presence of trained staff in The field of providing services to the disabled, in the category of collections, the existence of books in various formats and the category of equipment and information technology, the existence of assistive technologies (CCTV, Braille printers, screen magnification, etc.) have had the highest frequency. Conclusion: Identifying the services needed by the disabled and the characteristics of a library for the disabled can help in making informed decisions to provide appropriate services in libraries, especially public libraries. Public libraries must provide facilities and features for people with disabilities to use the services and access the information they need. Libraries should, in addition to assessing the needs of different groups of people with disabilities and the organizations and associations that support them, have the necessary planning and budget by providing the appropriate collection, accessible building, various services and programs, and the existence of various equipment and technologies.

Background: Tracheal stenosis remains a challenge in the thoracic surgery field. Recognizing the hot topics and major concepts in this area would help the health policy makers to determine their own priorities and design the effective research plans. The present study analyzed and mapped the topics and trends of tracheal stenosis studies over time as well as authors' and countries' contributions. Materials and Methods: Search results were obtained employing Bibexcel. To determine cold and hot topics, co-occurrence analysis was applied using three international databases 'Web of Science', 'PubMed' and 'Scopus'. Appropriately, different categories in the articles such as keywords, authors, and countries were explored via VOSviewer and NetDraw. Afterward, the trends of research topics were depicted in four time-intervals from 1945 to 2015 by ten co-occurrence terms. Results: The majority of articles were limited to case series and retrospective studies. The studies had been conducted less frequently on prevention, risk factors and incidence determination but extensively on treatment and procedures. Based on the articles indexed in WOS, 45 countries and 8,260 authors have contributed to scientific progress in this field. The highest degree of cooperation occurred between the USA and England with 15 common papers. Conclusions: Most of the published literature in tracheal stenosis research field was about surgical and non-surgical treatments. Conducting the screening and prevention studies would diminish the burden of this disease on the health system as well as the patients and their families' well-being. [ABSTRACT FROM AUTHOR]
