Background: COVID-19 is a multi-systemic infectious disease. Nearly 20%-30% of hospitalized patients have evidence of acute myocardial involvement, portending a poorer prognosis. However, information about the long-term effects of the disease on cardiac functions is sparse. As a result, there is a growing concern about the cardiac sequelae of COVID-19 among survivors. This study aimed to investigate the effects of prior mild-moderate COVID-19 infection on cardiac functions, using speckle tracking echocardiography. Methods: Patients who have been diagnosed with COVID-19 within the previous 6 months and age-, sex-, and risk factor-matched healthy adults were included. All patients underwent a comprehensive echocardiographic examination. Both conventional and 2-dimensional speckle tracking echocardiographic measurements were performed. Serum cardiac biomarkers were also obtained on the day of the echocardiographic study. Results: Compared with healthy controls, COVID-19 survivors had similar left and right ventricular longitudinal strain values at 6 months. Also, left and right atrial peak systolic strain values did not differ between the groups. Conclusion: Our study is valuable in putting forth the unaffected ventricular and atrial functions on long term in uncomplicated COVID-19 cases and may decrease the survivors' anxiety and the number of unnecessary applications to cardiology clinics.

This study was carried out in order to identify green (environmentally friendly) practices in university libraries in both institutional and individual contexts. Within the scope of this research, descriptive method was used, and also two questionnaires were used as data collection tools from library directors and librarians. Within the frame of the study, online questionnaire was sent to 165 directors and 1614 librarians working in 165 university libraries (out of 182 in total) in Turkey. 45 directors and 341 librarians responded to the survey. The directors' survey has six main sections including sustainable environment, water saving, energy saving, sustainable resources and materials, indoor air quality, innovation in design and implementation, and aims to collect information on an institutional basis. The librarian survey consists of three main parts which are demographic information, environmental awareness and attitude in daily life, and green libraries. The obtained data were analyzed by IBM Statistics SPSS 23.0 software package. In the study, it was found out that even though university libraries in Turkey fulfill some criteria such as proximity to public transportation, use of alternative options in transportation and water-efficient plumbing, monitoring water use, turning off electrical appliances when not in use, use of double glazed windows, taking precautions against paper waste with recycling or donation of printed resources, there are still deficiencies. Also, differences between universities have been identified in terms of green approaches/implementations and some libraries such as Atılım, Bilkent, Başkent and Yaşar University libraries have been observed to be greener than others within sustainable environment, water and energy saving, sustainable materials-resources, indoor air quality and design and application innovations. Although librarians have a low level of perception and awareness in green libraries and environmental sustainability issues, they have positive opinions about the initiatives promoting education and awareness.

In this study predatory journals originated from Turkey in the Beall list, which situated in the context of the literature as an authority, have been identified and studied in detail. Results show that 3.2% of the journals in the list originated from Turkey. Accordingly, it is seen Turkey ranks second after India in the list. While the number of Turkish journals in the list was at a certain level from 2003 to 2010 (seven journals in 2010), it started to show a sudden increase since 2011 and reached 41 in 2016. We believe that the criteria discussed by the researchers (the criteria set by Beall or the others who criticize the Beall list) will guide the researcher to determine the predatory journals in order to be able to avoid them.

The possibility of creating and easily distributing something via a digital platform creates an enormous material volume. With the increase of scientific publications it becomes harder for scholars to choose the most related and significant resources from the others (Henning & Gunn, 2012). Bibliometrics measures the impact of scholars between each other, but the impact of articles across the entire web is not limited by this. On the other hand, altmetrics measures the impact of articles from the web, alongside bibliometric data. The aim of this study is to investigate the probable relationships between traditional metrics and altmetrics by analysing the PLoS Article-Level Metric (ALM) dataset. [ABSTRACT FROM AUTHOR]

Many universities have developed interactive and web-based campus maps. The spatial features of Geographical Information Systems (GIS) are usually incorporated in such maps, thereby facilitating visual searches. The aim of this study is to design and develop an interactive, user-friendly and web-based Beytepe Campus Map to process visual queries. The Google Maps API application builder has been used to design the user interface for our campus map. Data has been gathered about several different places on campus and they were tagged on the map using CommunityWalk's place-pointing feature. Brief notes (dormitory capacities, pictures, phone numbers, etc.) about each place using explanation buttons have been added. A simple ontology comprising eight categories, each with its own sub-categories to represent the places at the Beytepe Campus has been developed. The MapCruncher software of Microsoft has been used to cut the map and paste it on to Google Maps for predefined granularity levels. A new button added to place the Beytepe campus map on Google Maps. To develop the mashup application using Google Maps API, we wrote the programming code using the Google Code Playground. We used JavaScript and JavaScript libraries to modify the user interface. In summary, the new campus map is more functional. The user interface can be improved in terms of design and functionality by adding new features. [ABSTRACT FROM AUTHOR]
