Item Bilgisayar Programlama Derslerinde Öğrenme Motivasyonu Ölçeğinin Türkçe Uyarlaması: Geçerlilik ve Güvenilirlik Çalışması(Başkent Üniversitesi Eğitim Bilimleri Fakültesi, 2018) Avcı, Ummuhan; Ersoy, Halil; 0000-0001-7007-1478; 0000-0003-1598-7656Bu araştırmanın amacı Law, Lee ve Yu 2010 tarafından geliştirilen Bilgisayar Programlama Derslerinde Öğrenme Motivasyonu Ölçeği’ni Türkçe’ye uyarlamaktır. Bu amaçla geçerlik ve güvenirlik analizlerini yapmak üzere altı faktör bireysel tutum ve beklenti, zorlayıcı amaçlar, belirgin hedefler, ödül ve takdir, ceza, sosyal baskı ve rekabet ve 19 maddeden oluşan altılı Likert tipindeki ölçek, özel bir üniversitede okuyan 312 mühendislik fakültesi öğrencisine uygulanmıştır. Doğrulayıcı faktör analizi sonuçları incelendiğinde, ölçeğin altı faktörden oluştuğu doğrulanmış ve ölçeğin uyum iyiliği indislerinin yeterli düzeyde olduğu görülmüştür. Ölçeğin güvenilirliği Cronbach alfa iç tutarlılık katsayısı ile değerlendirilmiştir. Cronbach alfa katsayısının ölçeğin tamamında 0.90 olduğu ve faktörler bazında 0.71 ile 0.83 arasında değiştiği görülmüştür. Bu sonuçlar ölçeğin, bilgisayar programlama derslerinde öğrenme motivasyonunun ölçülmesinde geçerli ve güvenilir bir ölçme aracı olduğunu göstermektedir. The aim of this study is to adapt the Learning Motivation in Computer Programming Courses Scale developed by Law, Lee ve Yu 2010 to Turkish. In order to determine its validity and reliability, the scale consisting of 19 six-point Likert-type items within six factors individual attitude and expectation, challenging goals, clear direction, reward and recognition, punishment and social pressure and competition was applied to 312 engineering faculty students at a private university. When the results of the confirmatory factor analysis were examined, it was confirmed that the scale had six factors, and the goodness of fit indices are at an acceptable degree. The reliability of the scale was assessed by the Cronbach alpha internal consistency coefficient. The Cronbach’s alpha coefficiencies were found to be 0.90 for the whole scale and between 0.71 and 0.83 for the factors. These results show that scale is a valid and reliable measuring tool for learning motivation in computer programming coursesItem Yükseköğretimde Uzaktan Eğitim Uygulamalarının İncelenmesi: Türkiye Örneği(Başkent Üniversitesi Eğitim Bilimleri Fakültesi, 2017) Cabi, Emine; Ersoy, Halil; 0000-0002-7488-0309; 0000-0003-1598-7656Bu çalışma 2010 yılından 2016 yılına kadar, Türkiye yükseköğretiminde uzaktan eğitim çalışmalarının sayısal veriler ışığında incelenmesini amaçlamaktadır. 2010 ile 2016 yılları arasındaki yükseköğretimdeki öğrenci sayıları, uzaktan eğitim veren ön lisans, lisans ve yüksek lisans programlarına yerleşen öğrenci sayıları ve mevcut program sayılarının dağılımları incelenmiştir. Ön lisans ve lisans seviyesinde 20102015 arası uzaktan eğitimde öğrenim gören öğrenci sayılarına ulaşılabilirken, yüksek lisans seviyesinde sadece 2014-2015 ve 2015-2016 eğitim-öğretim dönemlerindeki program ve öğrenci sayılarına ulaşılabilmiştir. Ayrıca çalışmada genel ve programlara yerleşen öğrenci sayılarının yıllara göre değişimleri de incelenmiştir. Yapılan çalışma durum çalışması olduğundan mevcut durumu boylamsal olarak ortaya koymaktadır. Bu bağlamda, yeni açılması düşünülen uzaktan eğitim programlarının yapılandırılması çalışmalarında katkısı olabileceği düşünülmektedir. This study aims to investigate distance education implementations in higher education of Turkey from 2010 to 2016 by numeric data. For this purpose, the numbers and distribution of students at vocational schools, undergraduate and graduate level programs being executed totally in distance education method were analyzed. While it was possible to reach to the numbers of distant students at vocational schools and undergraduate levels between 2010 and 2015, only 2014-2015 and 2015-2016 years’ data were been able to obtained at graduate level. Moreover, the change in the numbers of distant students by years was investigated. Hence it is a case study, it portrays the existing situation longitudinally. In this context, it is believed that the study will contribute to the actions targeting to open new distance education programsItem Technologies Used in Distance Education During the Covid-19 Global Pandemic and Investigation of the Opinions of Teachers: The Case of Başkent University(Başkent Üniversitesi Eğitim Bilimleri Fakültesi, 2022) Cabi, Emine; Ersoy, Halil; 0000-0002-7488-0309; 0000-0003-1598-7656Bu çalışmanın amacı, içerisinde bulunduğumuz Covid-19 küresel salgınının paralelinde gelişen yeni normalleşme sürecinde öğretim elemanlarının uzaktan eğitim uygulamalarına yönelik görüşlerini incelemektir. Çalışma, nicel araştırma yöntemlerinden tarama araştırması ile gerçekleştirilmiştir. 2020-2021 güz yarıyılı sonunda, Başkent Üniversitesi bünyesinde bulunan 502 öğretim elemanı çalışmaya katılmıştır. Veri toplama aracı olarak araştırmacılar tarafından seçenekli, likert ve açık uçlu sorulardan oluşan anket kullanılmıştır. Araştırma amacına paralel olarak ankette dört farklı boyutta veri toplanmıştır: Üniversitedeki uzaktan eğitim teknolojilerinin mevcut durumu, öğretim elemanlarının kurumsal desteğe, kullanılan senkron-asenkron araçlara ve ölçme-değerlendirme uygulamalarına yönelik görüşleri. Verilerin analizinde içerik analizi ve betimsel analiz tekniği kullanılmıştır. Elde edilen bulgulara göre kurumdaki derslerin büyük çoğunluğunun uzaktan öğretim ile yürütülebildiği belirlenmiştir. En fazla kullanılan asenkron platformun kurumsal olarak kullanılan Moodle® tabanlı Öğretim Yönetim Sistemi (ÖYS), senkron platformların ise Microsoft Teams ve Zoom olduğu görülmüştür. Öğretim elemanlarının uzaktan öğretimde ders içeriklerini paylaştıkları ÖYS’nin teknik kapasitesinin, ara yüz tasarım/kullanım kolaylığının, sınav yapma özelliklerinin ve sistem içerisindeki yardım materyallerinin yeterli olduğunu düşündükleri saptanmıştır. Öğretim elemanlarının kullandığı senkron platform araçlarına bakıldığında, “kullanım kolaylığı”, “görüntülü katılım özelliği/kapasitesi” ve “canlı toplantı sırasında eğitmen kontrolü” kategorilerinde Zoom® platformu; “canlı ders kayıtlarının paylaşımı” kategorisinde Microsoft Teams® platformu en fazla yeterli bulunanlar arasındadır. Kurumda pandemi sürecindeki uzaktan öğretimde hemen her türlü ölçme aracı ve yöntemi kullanılmış olduğu görülmekle birlikte, ağırlıklı olarak “kamera gözetimli çevrimiçi sınav” kullanımı ve “esnek zamanlı ödev ve proje” kullanımının söz konusu olduğu ortaya çıkmıştır. Öğretim elemanlarına göre uzaktan öğretimde en çok güvenilen ölçme aracının sözlü sınav ve proje olduğu, en az güvenli olan ölçme aracının ise gözetimsiz çevrimiçi sınavların olduğu ifade edilmiştir. Elde edilen önemli bulgular tartışılmış ve hem araştırmaya hem de uygulamaya yönelik önerilerde bulunulmuştur. The aim of this study is to examine the views of the instructors on distance education practices in the new normalization process that had been aroused with the global Covid-19 epidemic we are in. The study was carried out with survey research, one of the quantitative research methods. At the end of the 2020-2021 fall semester, 502 faculty members of Başkent University participated in the study. As a data collection tool, a questionnaire was created by the researchers and was composed of multiple choise, likert type and open-ended questions. The data were obtained by the questionnaire with four categories, which are the current situation of distance education technologies in the institution, instructors’ opinions about the institutional support, about usefulness of synchronous-asynchronous tools and about measurement-evaluation practices. Content analysis and descriptive analysis techniques were used in the data analysis. It was found that most of the courses in the institution were conducted remotely. The mostly used asynchronous platform is Moodle® based institutional web site, namely Learning Management System (LMS), and synchronous platforms are Microsoft Teams® and Zoom®. Regarding the LMS, where the lecturers share the course content in distance education practices, it’s technical capacity, interface design/ease of use, online exam features and support materials in the system were found to be sufficient in general for the instructors. Considering the synchronous tools, Zoom® was found to be more adequate in the categories of “ease of use”, “video-enabled participation feature/capacity” and “instructor control during the live meeting”, while Microsoft Teams® was stated to be more adequate in the category of “sharing of live lecture recordings”. Although various kinds of measurement tools have been used in the institution, there was mainly more tendency in use of “online exams with camera surveillance” and “flexible timely assignments and projects”. According to the instructors, while the most reliable measurement tools or types were “the oral exam” and “the project”, the least secure one was the “unsupervised online exam” in the distance education. Those important findings were discussed, and suggestions were made for both further research and practices.Item Effect Of Tacrolimus In The Inner Ear Of Rats(2022) Uysal, Fatmanur; Erbek, Selim S.; Erbek, Seyra; Culhaoglu, BeldePurpose: Tacrolimus, an immunosuppressive agent, is used especially after organ transplantation. It has been asserted that tacrolimus has protective effects on the auditory system in some studies while it has negative effects in other studies. The purpose of our study is to investigate the effect of tacrolimus on the inner ear of the rats. Materials and Methods: 20 healthy Sprague Downey male rats weighing 250-350 grams were included in our study. The first group of rats were given 1mg/kg tacrolimus (n:7), the second group of rats were given 0.1 mg/kg tacrolimus (n:7), and the third group (n:6) was the non-administered control group. The first measurements of all rats were taken with distortion-product otoacoustic emission before starting the experiment. Then, tacrolimus drug was administered by gavage method to the 1st and 2nd groups along 30 days. The last measurement was repeated on the 30th day. Results: According to the results of the first measurements, emission was obtained in all rats and the responses were found to have similar characteristics. Similarly, the difference between the signal noise rate values in the last measurements taken from the groups not show any statistical significance. Conclusions: Based on the distortion-product otoacoustic emission measurements, it can be said that Tacrolimus does not have ototoxic effects on the auditory system of rats considering the administered dosage and time.Item Safety and efficacy of angio-seal use in patients with acute ischemic stroke who received thrombolytic therapy and underwent mechanical thrombectomy(2022) Tanburoglu, Anil; Karluka, Ismail; Mazican, Mustafa; Andic, CagatayPurpose: This study aims to evaluate the efficacy and safety of closure of the femoral artery access site using the Angio-Seal Vascular Closure Device in patients who underwent bridging intravenous thrombolytic therapy and subsequent mechanical thrombectomy (MT). Materials and Methods: The retrospective, observational study was performed in patients who were diagnosed with acute ischemic stroke and treated with MT after bridging IVT between September 2018 and September 2021. A total of 97 patients whose femoral artery access sites were closed with Angio-Seal after the procedure was performed were included in the study. Primary demographic data, accompanying risk factors, major and minor complication rates, frequency distributions of categorical variables, and descriptive statistics of quantitative data were calculated and recorded. Results: It was found that 96.9% of the patients did not have major complications, where 97.9% did not have minor complications either. Successful hemostasis was achieved in the groin region in all patients. Major complications observed were recorded as follows: 1 (1%) pseudo-aneurysm, 1 (%) inguinal incision site infection, and 1 (1%) Angio-Seal placement failure. No major complications were observed in 98.2% of those using 6 Fr (French) Angio-Seal and 95.1% of those using 8 Fr Angio-Seal. Conclusion: The findings of the study indicate that Angio-Seal is an effective and safe method for providing groin hemostasis in patients with acute ischemic strokeItem The Importance of Health Literacy and Health Communication: Evaluation of Delayed Admission Time to Hospital in Women During Myocardial Infarction in Turkey in Terms of Gender Inequality(2021) Altun, Armagan; 0000-0002-3233-8263; 33709913; ABB-5844-2020Item Can Digital Game Play Improve Older Adults' Cognitive Skills?(2021) Secer, IlmiyeCognitive skills are essential for the performance of basic and instrumental daily living activities such as self-care, medication, and finance management. A decline in cognitive abilities with increasing age thus hinders older adults' ability to remain independent in society and negatively influences their quality of life. Therefore, many studies have investigated ways that can maintain and effectively improve such skills. Digital games have become a favored leisure activity by all age groups and are played for entertainment and stress relief. In this context, the ease with which digital games can be played within the home and their entertaining nature have led researchers to examine their effectiveness in enhancing older adults' cognitive skills. Although the findings indicate cognitive advantages, such as improved reaction times, working memory, and task-switching abilities, many questions require further clarification before claiming that digital game play is an effective cognitive training regime. Therefore, the current review aims to examine the cognitive advantages of digital games for older adults and suggests future research directions. The following topics need to be further explored: the existence of far transfer effects, that is, whether such improvements lead to better performance of daily activities, the long-term maintenance of enhanced skills and the underlying responsible mechanisms, the ecological validity of digital games, and digital games' provision of benefits beyond cognitive simulations. Furthermore, the importance to consider placebo effects, which was suggested by Boot, Blakely, and Simons (2011) and Boot, Simons, Stothart, and Stutts (2013), is emphasized.Item Antibody Screening and Risk Assessment of Healthcare Professionals in the COVID-19 Pandemic(2021) Gumus, Hatice Hale; Demiroglu, Yusuf Ziya; Aliskan, Hikmet Eda; Odemis, İlker; Ceylan, Ozgur; Pocan, Ahmet Gurhan; Karagum, Ozlem; 0000-0001-9060-3195; 0000-0003-2638-0163; 0000-0002-9866-2197; 0000-0003-2638-0163; 0000-0001-6910-7250; 0000-0003-0681-8375; 0000-0003-3128-1602; 0000-0001-9071-9606; 34416802; AAE-2282-2021; AFK-3690-2022; AAX-9250-2021; AAZ-9711-2021; AAG-2486-2022; AAK-8276-2021; U-4084-2017; AAE-6310-2021; AAJ-2108-2021Globally 364102 healthcare professionals have been infected with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and 1253 of them died until 15 January 2021. Healthcare professionals serving at the forefront of combating the pandemic are in the high risk group. In our country, the data about coronavirus-2019 (COVID-19) among healthcare professionals are limited. The aim of this study was to investigate the anti-SARS-CoV-2 IgG seroprevalence in healthcare professionals, to evaluate the risks they encountered during work, and to examine their relationships with antibody positivity. A total of 572 healthcare professionals serving in various units of our hospital participated in our study and the presence of anti-nucleocapsid IgG was investigated by chemiluminescent microparticle immunoassay (SARS-CoV-2 IgG test, Abbott Laboratories Diagnostics, USA) method in serum samples collected between May 18, 2020 and June 30, 2020. The demographic characteristics, medical history, work conditions, medical procedures performed and possible risk factors were questioned with a questionnaire form. The average age of the participants was 33.5 +/- 9.2 (19-61) years, and 62.9% (360/572) of them were women. In our study, the anti-SARS-CoV-2 IgG seroprevalence was 3.7% (21/572). The association of the antibody positivity with age, gender and occupational status was not statistically significant (p> 0.05). Comorbid diseases which were significantly higher in seropositive healthcare professionals were hypertension (19%) and diabetes mellitus (14.3%) (p< 0.05). It was observed that antibody positivity was significantly higher in healthcare professionals working in high (52.4%) and medium risk (33.3%) areas, those who treat and/or examine patients with suspicious or positive COVID-19 (66.7%) and those who spend more than 30 minutes in COVID-19 patient rooms (76%) (p< 0.05). The symptoms associated with seropositivity in healthcare workers with a history of symptoms (46%) were loss of smell (23.5%), loss of taste (20.0%) and respiratory distress (16.7%) (p< 0.05). It was observed that the probability of being infected with SARS-CoV-2 increased 12 times if there was a colleague with COVID-19 in the hospital, four times if there was a patient in the house/lodging and six times if there was an infected person in the social environment (p< 0.05). The rate of those who had the flu vaccine among the participants was 10.8% (62/572) and 9.7% of them were found to be anti-SARS-CoV-2 IgG positive (p< 0.05, 95% CI= 1.31-9.48). The seropositivity was significantly higher in non-smokers (4.8 %) compared to smokers (0.0%) (p< 0.05). In our study, it was determined that the rate of seropositivity was 12 times higher in healthcare professionals who stated that they received hydroxychloroquine prophylaxis due to risky contact compared to those who did not receive prophylaxis (p< 0.05, 95% CI= 4.11-40.64). The ratio of the personnel who answered "always" to the frequency of wearing gloves, masks, goggles/face shields and overalls was 85.7%, 96.9%, 62.1% and 65.4%, respectively. In conclusion, regular and large-scale sero-epidemiological screening of healthcare professionals in the COVID-19 pandemic can contribute to the control of the pandemic by providing a better understanding of transmission dynamics and risk factors.Item A Qualitative Study On The Communicative Needs, Expectations And Experiences During Covid-19 Pandemic: 65 Years And Over Ankara Sample(2021) Kilic, Nilufer Pinar; Ozdemir, B. Pinar; Hizal, G. Senem Gencturk; Aktas, MelikeThis study examines the high-risk group of individuals age 65 and over who most frequently experience the negative consequences of Covid-19. We review their communicative needs and expectations, knowledge and information sources, and risk information and knowledge patterns. We conducted semi-structured interviews with 47 people aged 65 and over residing in Ankara. We evaluated our results in the context of The Social Amplification of Risk Framework, considering the major communication stations disseminating risk information. We found that during the Covid-19 pandemic, individuals aged 65 and over accessed risk information through new media and traditional media, and interpersonal communication, especially with close family and children, served as a primary information source during the pandemic. The trust factor, particularly regarding medical expertise, was an essential criterion in evaluating information. The communicative needs and expectations changed for this high-risk group. The need for improved digital communication capabilities become apparent during the pandemic crisis. Suggestions that consider public perspectives and risk perceptions while incorporating the relationship between risks and communication processes may contribute to structuring impactful risk communication activities.Item Ageism During the Covid-19 Pandemic: Discussion and Recommendations(2021) Madran, H. Andac DemirtasThe spread of the coronavirus disease 2019 (Covid-19) was labeled a "pandemic" by the World Health Organization on March 11, 2020. It has caused not only health-related issues but also economic, educational, psychological, and social problems. Further, discrimination associated with the pandemic has been observed around the globe. Besides the obvious negative consequences faced by the individuals targeted, pandemic-related discrimination has affected the spread of the virus by influencing public attitudes toward disease prevention and the restrictions imposed by authorities. Discrimination toward foreigners, minorities, and certain religious groups (e.g., Muslims) increased during this period. Additionally, the pandemic saw ageism spread rapidly to become more visible than ever. Acknowledging that Covid-19 poses a higher risk for individuals over a certain age, several countries implemented restrictions specific to those age groups. However, this practice resulted in the emergence of problems that were not considered initially, especially the escalation of ageism. This study examines ageism during the Covid-19 pandemic based on major theories and current research. First, discrimination and ageism are defined in detail. Then, pandemic-related ageism is discussed within the framework of basic theoretical approaches. Finally, recommendations for preventing ageism related to the pandemic and in general are presented.
