Adoption and use of learning management systems in education: The role of playfulness and self-management

This article investigates the factors affecting primary and secondary education teachers' behavioral intention to adopt learning management systems (LMSs). Information technology (IT) innovations have the power to change the way we work, educate, learn, and basically the way we live. The effect of IT innovations on education makes it critical to understand the current usage situation of LMSs and the factors affecting their adoption by teachers. The unified theory of acceptance and use of technology (UTAUT) was extended with factors from education and game-based learning literature. In order to see the effect of individual- and organizational-level characteristics, multi-group structural equation modeling (SEM) analysis was conducted and discrepancies in relationships were reported. Evaluation of users and non-users and teachers of different fields were also compared to each other. The findings of this study not only contribute to theory through the development and testing of a thorough model relating technology features and individual characteristics to behavioral intention to use, but also offer strong implications for practitioners who would like to increase LMS usage and create a more effective learning environment.WOS:000615607100001Scopus - Affiliation ID: 60105072Scopus - Affiliation ID: 60105072Science Citation Index Expanded - Social Sciences Citation IndexQ2 - Q3ArticleUluslararası işbirliği ile yapılmayan - HAYIRFebruary2021YÖK - 2020-2

Factors Affecting Job Satisfaction and Burnout of Midwives In Aydın, Turkey

Giriş: İş doyumu ve tükenmişlik verilen hizmetlerin kalitesiyle çok yakın ilişkilidir. Bunlar kültürel özellikler de gösterebilen birçok faktör tarafından etkilenirler. Amaç: Ebelerin iş doyumu ve tükenmişlik durumları ile etkileyen faktörleri belirlemektir. Yöntem: Tanımlayıcı ve kesitsel özellikteki çalışma, Aydın İl merkezindeki 1. 2. ve 3. basamak sağlık kurumlarında çalışan ebelerde gerçekleştirilmiştir. Örneklemi 193 ebe oluşturmuştur. Veriler soru formu, Maslach Tükenmişlik Envanteri ve Minnesota İş Doyumu Ölçeği ile ebelerin öz bildirimlerine göre toplanmış ve tanımlayıcı istatistikler, t testi, Mann Whitney U testi, Kruskall Wallis, ANOVA ve linear regresyon analizleri ile değerlendirilmiştir. Bulgular: Yaş ortalaması 35.35±4.68 olan ebelerin %62.7'si ön lisans mezunu, %87'si evli ve %50.8'i 1. basamak sağlık kurumlarında çalışmaktadır. Ebelerin %59.6'sı çalıştığı klinikten memnundur ve %52.4'ü mesleği kendine uygun bulmaktadır. Genel olarak ebelerin iş doyumları orta seviyede, tükenmişlikleri ise ileri düzeydedir. Ebelerin dışsal doyumlarına göre içsel doyumları daha fazladır ve en fazla "başkaları için bir şeyler yapabilme"den doyum sağlamaktadırlar. Buna karşın en tükenmiş oldukları konu "hastaların sorunlarını etkili bir şekilde çözme"'dir. Ebeler duygusal açıdan daha fazla tükenme yaşamaktadırlar. Ebelerin iş doyumlarını en fazla mesleği uygun bulma, çalışılan kurum ve birimden memnuniyet, hizmet verilen nüfus, aylık nöbet sayısı, aylık gelir, tükenmişliklerini ise mesleğin uygunluğu ve çalışılan klinikten memnun olma durumu etkilemektedir. Sonuç: Bulgular ebelerin mesleğin algılanması ve çalışma koşullarına bağlı olarak orta düzeyde bir iş doyumu, buna karşın ileri düzeyde tükenmişlik yaşadıklarını göstermektedir. Bu nedenle, ebelerin meslek algıları ve çalışma koşullarının iyileştirilmesine yönelik düzenlemelerin yapılması önemli olacaktır. Backround: Job satisfaction and burnout are strongly related to qualities of services given. They were affected by a complex network of various factors which may have cultural characteristics. Objectives: To determine job satisfaction and burnout levels of midwives and affecting factors. Methods: The cross-sectional descriptive study was conducted in 1st, 2nd and 3rd levels health institutions in Aydın. Sample included 193 midwives. Data were collected during 12.2007-01.03.2008 via a questionnaire, Maslach Burnout Inventory and Minnesota Job Satisfaction. Questionnaire by midwives self-reports, and analyzed by descriptive statistics, t-test, Mann Whitney U tests, Kruskall Wallis, ANOVA and linear regression analyses. Results: Mean age of midwives was 35.35±4.68. 62.7% of them were high school graduate, 87% were married, and 50.8% were working at 1st level health institutions. In general, the job satisfaction of midwives was moderate, but their burnout levels were higher. Internal satisfactions of midwives were higher than their external satisfactions, and they were satisfied by "doing something for others" at most. In contrast, the issue burned out them at most was "solving patients' problems effectively". Midwives experience emotionally more burnout. The job satisfactions of midwives were affected especially by finding the profession suitable for self, satisfaction with worked institution and unite, served population size, number of monthly watches and monthly salary, whereas their burnout levels were affected mostly by the suitability of the profession and satisfaction with the worked clinic. Conclusion: The findings of this study indicate that midwives experience a moderate job satisfaction in dependence of their perception of the profession and working conditions, in contrast, higher burnout. Thus, arrangements aiming at improvements in perceptions of the profession and working conditions would be important

The phenotypic diversity and fruit characterization of winter squash (Cucurbita maxima) populations from the Black Sea Region of Turkey

Winter squash are one of the most important Cucurbit crops in Turkey. Winter squash populations show great diversity in morphological characteristics, particularly fruit length, fruit diameter, fruit shape, fruit brightness, skin thickness , flesh thickness and colour in the Black Sea region of Turkey. In this research, 115 populations of winter squash, Cucurbita maxima Duch, were collected from different provinces of the Black Sea region in 2006 and 2007 and phenotypic diversity in their fruit characters was assessed. The collection showed appreciable phenotypicvariation in fruit shape, fruit colour, fruit brightness, fruit dimension and fruit weight. Cluster and principal component analysis (PCA) were performed to determine relationships among populations and to obtain information on the usefulness of those fruit characters for the definitionof groups. Cluster analysis based on 14 quantitative and 7 qualitative variables identified 10 different groups. The first five principal component axes accounted for 65.0% of the total multivariate variation among the populations. The greater part of variance was accounted for byfruit weight, fruit diameter, fruit length, length of seed cavity and flesh thickness. This evaluation of fruit trait variability can assist geneticists and breeders to identify populations with desirable characteristics for inclusion in variety breeding programs

A randomized, prospective clinical study evaluating effectiveness of a bulk-fill composite resin, a conventional composite resin and a reinforced glass ionomer in Class II cavities: one-year results

Bulk-fill restorative materials such as bulk-fill composite resins and high viscous glass ionomer cements have become very popular materials in operative dentistry because their application is easy and time-saving. Objectives: The aim of this clinical study was to evaluate the clinical performance of a highly viscous reinforced glass ionomer material, a bulk-fill composite resin and a micro hybrid composite resin in Class II restorations. Methodology: In total, 109 Class II restorations were performed in 54 patients using three different restorative materials: Charisma Smart Composite (CSC); Filtek Bulk Fill Posterior Restorative (FBF); Equia Forte Fil (EF). Single Bond Universal adhesive (3M ESPE, Germany) was used with composite resin restorations. The restorations were evaluated using modified USPHS criteria in terms of retention, color match, marginal discoloration, anatomic form, contact point, marginal adaptation, secondary caries, postoperative sensitivity and surface texture. The data were analyzed using Chi-Square, Fischer's and McNemar's tests. Results: At the end of one year, 103 restorations were followed up. No changes were observed during the first 6 months. At the end of one year, there were small changes in composite restorations (FBF and CSC) but no statistically significant difference was observed between the clinical performances of these materials for all criteria (p>0.05). However, there was a statistically significant difference between EF, FBF and CSC groups in all parameters except marginal discoloration, secondary caries and postoperative sensitivity in one-year evaluation (p<0.05). Conclusion:Bulk-fill composite resins and conventional composite resins showed more successful clinical performance than highly viscous reinforced glass ionomers in Class II cavities

Bisfenol A'nın elektrokimyasal yöntemler ile arıtılabilirliğinin incelenmesi

06.03.2018 tarihli ve 30352 sayılı Resmi Gazetede yayımlanan “Yükseköğretim Kanunu İle Bazı Kanun Ve Kanun Hükmünde Kararnamelerde Değişiklik Yapılması Hakkında Kanun” ile 18.06.2018 tarihli “Lisansüstü Tezlerin Elektronik Ortamda Toplanması, Düzenlenmesi ve Erişime Açılmasına İlişkin Yönerge” gereğince tam metin erişime açılmıştır.Bisfenol A (BFA) farklı kimyasal maddeler ile birleştirilerek daha çok endüstriyel sektörde plastik malzeme ve metal kaplamalarında kullanılan kimyasaldır. Östrojenik hormon aktivitesini bozmakla beraber literatürde endokrin sistemi bozucu kimyasallar arasında gösterilmektedir. Günlük hayatımızda sık kullandığımız eşyalardan ve gıda maddelerinin kaplamalarından insana geçebildiği bildirilmiş ve özellikle doğum öncesi dönemlerde maruz kalınabilen BFA'nın kanıtlanmış birçok zararları bulunmaktadır. Endüstriyel faaliyetler için üretilen ve çevreye salınan BFA atıksu arıtma tesisleri çıkış sularında, çöp sızıntı suyunda ve her türlü yüzey akış sularında görülmüştür. Bu tez çalışmasının asıl amacı laboratuvar şartlarında hazırlanan sentetik BFA çözeltisinin elektrooksidasyon-ozon ve ozon prosesleri ile beraber arıtılabilirliğinin araştırılmasıdır. İki prosesin beraber kullanıldığı (EO+O3) sisteminde BFA giderme verimine etkisi araştırılmıştır. BFA konsantrasyonundaki azalmalar gözle görülür bir şekilde oluşmuş, sadece ozon (O3) ile arıtımda ise giderim sağlanmış fakat ikili prosese göre daha az verim elde edilmiştir. Çalışmada pH, akım yoğunluğu, ozon dozu ve süre parametrelerinin BFA giderme verimine etkisi analiz edilmiştir. Aktif anodik oksidasyon ile gerçekleştirilen elektroooksidasyonda anot olarak Ti/RuO2(0,70)-IrO2(0,30) materyali kullanılmıştır. EO+O3 prosesinde optimum şartlar pH 7, 1,5 g/L.H ozon dozu, 4,57 mA/cm2 akım yoğunluğu ve 25 dak. olarak bulunmuştur. O3 prosesinde ise pH 7, 1,5g/L.h ozon dozu ve 25 dak. olarak bulunmuştur. Bu şartlarda BFA giderme verimleri EO+O3 için %90,68 iken O3 için %83,92 olarak bulunmuştur. Her iki proses için farklı kinetik modelleri ile hesaplar yapılmış olup her iki proses için en uygun kinetik model 2. Mertebe bulunmuştur. 2. Mertebe kinetik modele göre regresyon katsayıları (R2) EO+O3 için 0,94 ve O3 için 0,92 olarak, reaksiyon hızları (k) sırası ile 1,8x10-2 ve 9x10-3 olarak bulunmuştur. Farklı parametrelerde yapılan çalışmalarda görüldüğü üzere BFA numunesinin gideriminde EO+O3 prosesi kullanılabildiği ve sadece O3 prosesine göre daha verimli bir arıtım gerçekleştirdiği belirlenmiştir. İki proseste de BFA parçalanması sonucu yan ürün oluşmadığı gözlemlenmiştir.Bisphenol A (BPA) is a chemical used in plastic materials and metal coatings in the industrial sector and combined with different chemicals. Although it destroys estrogenic hormone activity, it has been shown in the literature among endocrine disrupting chemicals. In our daily life, it has been reported that it can be passed from the items we use frequently and from the coatings of foodstuffs to human and there are many proven damages of BFA which can be exposed especially in prenatal periods. BFA wastewater treatment plants produced for industrial activities and released to the environment were observed in wastewater, leachate and all surface waters. The main purpose of this thesis study is to investigate the treatability of synthetic BFA solution prepared by laboratory conditions together with electrooxidation-ozone and ozone processes. The effect of BFA removal efficiency on two different processes (EO+O3) was investigated. Decreases in BFA concentration were observed visually, but only in ozone (O3) treatment, but less efficacies were obtained. In this study, the effect of pH, current density, ozone dose and duration parameters on BFA removal efficiency were analyzed. Ti/RuO2(0,70)-IrO2(0,30) material was used as the anode in the electrooxidation by active anodic oxidation. The optimum conditions in EO+O3 process were pH 7, 1.5 g / L.H ozone dose, 4.57 mA/cm2 current density and 25 min. In the O3 process, pH 7, 1.5 g/L.h ozone dose and 25 min. In these conditions, BFA removal efficiencies were 90.68% for EO+O3 and 83.92% for O3. Calculations were made with different kinetic models for both processes and the second most appropriate kinetic model for both processes was found. Regression coefficients (R2) were found to be 0.94 for EO+O3 and 0.92 for O3, and reaction rates (k) were found to be 1.8x10-2 and 9x10-3, respectively. As can be seen from the studies carried out in different parameters, the EO + O3 process can be used together with the BPA sample, ıt was found that he did a more effective treatment than O3. As a result of BFA disintegration, it was found that there were no by-products in both processes

A model for a proficiency/final achievement test for use at Erciyes University Preparatory School

Ankara : Institute of Humanities and Letters of Bilkent University, 1994.Thesis (Master's) -- -Bilkent University, 1994.Includes bibliographical references leaves 51-53The goal of this study was to develop and pilot a model of a test based on course objectives that could be used for both a proficiency test and an achievement test for Erciyes University Preparatory School (EUPS) and that could be demonstrated to have reasonable reliability and validity. Only general English and reading skills were included in this pilot study. This newly developed model test, the Erciyes University Proficiency/Final Achievement Test (EUPFAT, or PAT, for short), consisted of 64 open-ended items such as short-answer, sentence completion, interrogatives, and rational cloze as recommended by a number of researchers (e.g., Heaton, 1988; Hill and Parry, 1992). No multiple-choice items were included as it has been suggested that they can produce negative backwash (Hughes, 1989). Twenty-two items testing general English skills and 42 items testing reading comprehension were included. There were 35 intermediate-level English as a Foreign Language students attending the prep school who volunteered to pilot the PAT. Of these 35 subjects, 30 also took the English as a Second Language Achievement Test (ESLAT) (1984), which was one of two criteria for estimating validity of the PAT. Teachers' evaluations of the 35 subjects who took the PAT were also used, as the second criterion. Following piloting, the PAT was scored independently by two scorers using an answer key prepared by the researcher. Inter-rater reliability was .99. The PAT was then evaluated for reliability and validity. Item analysis was also performed to identify items that should be replaced or rewritten for future administration of the tests. For internal consistency, the split-half reliability estimate of Pearson Product-Moment Correlation adjusted for length by Spearman-Brown Prophecy Formula, the Guttman split-half reliability estimate, the K-R 20, and the K-R 21 reliability formulas were used. The reliability coefficients estimated for internal consistency using these different split-half methods ranged from .87 to .96. The descriptive statistics of the PAT are as follows: N = 35, Mean = 29.86, Variance = 110.89, Standard Deviation = 10.53, Sum of Item Variance = 11.93. To determine the correlation between the PAT and the ESLAT, and between the PAT and the teacher evaluations, Pearson Product Moment Correlation (PPMC) was used. PPMC between the PAT and the ESLAT is .61, df = 28, p< .0004, and the correlation between the PAT and the teacher evaluation of subjects is .74, df = 33, p = .0000. Item analysis of the PAT has demonstrated that if the 19 of 64 items which are lying outside the acceptable range for item difficulty and discriminability are eliminated from the test, the rest of the test items can be used as part of a proficiency/final achievement test. Because the total number of subjects in this study was not very high (N = 35), generalizing the results to other EFL situations should be avoided. However, the results of this study should be taken into consideration while developing a new test, or evaluating existing tests by those who are interested or involved in language testing.Balkaya, FarukM.S

A macroscopic comparison study on main branches of arteria brachialis and arteria subscapularis in Southern Karaman and Hasak sheep breeds

Background: The Southern Karaman sheep, which is very fertile in terms of meat and milk production and is often preferred in livestock raising, is known as a domestic sheep breed. The Hasak sheep is a breed formed by the triple crossbreeding of the German Black-headed, Hampshire and Akkaraman breeds. Arterial feeding of the forelimb is provided by arteria axillaris, a continuation of arteria subclavia. In this study, it was aimed to examine the forelimb arteries in Southern Karaman and Hasak sheep breeds. Materials and methods: Totally, 8 Southern Karaman and 8 Hasak sheep were obtained from Konya Bahri Dagdas International Agricultural Institute. The sheep were anesthetised with xylazine and ketamine and extravasated by cutting the arteria carotis communis in the neck area of the sheep. The forelimbs of the sheep separated from the body were fixed in 10% formaldehyde solution and then dissections were made and the course and branching of the arteries were examined. Results: It was determined that the arteria brachialis was divided into two main branches as distal arteria brachialis and proximal arteria subscapularis at the articulatio humeri level of the arteria axillary. Arteria mediana, which is a continuation of arteria brachialis, was also examined in different parts of antebrachium and ended by splitting into branches. Conclusions: According to the findings of the Southern Karaman and Hasak sheep breeds, it was determined that the forelimb arteries had some anatomical differences but were similar in structure to many sheep breeds

An Al-Farabian Analysis of Social Disorder in Shakespeare’s Julius Caesar

Like many political philosophers, Al-Farabi was influenced by Greek philosophy and tried to define the best regime and ruler. However, much has changed in Al-Farabian scholarship since the 1970s, and 80s through deeper analyses of his philosophy, and translations of his works. The early Islamic philosopher Al-Farabi (870-950) played a key role in the revival of Plato and Aristotle’s works within Islamic philosophy, guiding others by studying and providing commentary on these texts. Al-Farabi and his political philosophy deal with the existence of human, ruling, and ruled organs in the body, the city and state which exemplify hierarchy, the features of a ruler, and the differences between excellent and ignorant cities in his on the Perfect State. In this sense, focusing on an Al-Farabian political reading of Julius Caesar, the aim of this study is twofold. Firstly, it examines the abovementioned socio-political issues to present the idea that such political qualities are also represented and questioned in Shakespeare's Julius Caesar. Secondly, the paper argues that the two works exhibit socio-political similarities inasmuch as Caesar’s portrayal of power relations within the play can be related to Al-Farabian understanding of the society, state, and rulership
