    Theoretical and experimental investigations are critical for accurately investigating the structure and physical properties of semiconductors, allowing their widespread use in power electronic devices. The heat capacities are important thermal properties needed to examine the electronic and electrical properties of device materials. The specific heat capacities of power electronic semiconductors, such as (GaN\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}GaN{\text{GaN}}\end{document}) gallium nitride, (SiC\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}SiC{\text{SiC}}\end{document}) silicon carbide, (Ga2O3\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}Ga2O3{\text{Ga}}_{2} {\text{O}}_{3}\end{document}) gallium oxide, and diamond, have been evaluated theoretically using the recently developed Einstein-Debye approximation. On the grounds of the Einstein-Debye approach, the derived general analytical expression for the calculation of the heat capacities is valid for the entire temperature range. The calculation results are compared with the previously available experimental and theoretical data for illustrating the correctness of the method. The evaluation and literature analysis confirm the effectiveness of the proposed method. As seen from the comparison with various results reported in the literaure, the results obtained from this approach are convenient and competitive

    New Co(III), Ni(II), Cu(II), and Zn(II) saccharinate (Sac) complexes bearing with N,N-bis(2-hydroxyethyl)ethylenediamine (N-bishydeten), namely [Co(2HN-bishydeten)2](Sac)⋅2H2O, [Ni(Sac)2(N-bishydeten)], [Cu(N-bishydeten)2](Sac)2 and [Zn(Sac)2(N-bishydeten)] were synthesized and characterized using UV–Vis, IR spectroscopy and magnetic susceptibility measurements. The crystal structures of the complexes were analysed by single crystal X-ray diffraction. Both N-bishydeten and Sac displayed coordination versality. The N-bishydeten ligands were octahedrally coordinated as two tridentate anionic ligands (2HN-bishydeten) (N, N, O-) to the Co(III) and two tridentate neutral ligands (N, N, O) to the Cu(II). The anionic Sac ligand was also located outside the coordination sphere in these complexes. However, the N-bishydeten ligand behaved as a tetradentate ligand (O, N, O, N) in the Ni(II) and Zn(II) complexes while two Sac ligands were coordinated the corresponding metals ions in a monodentate fashion, one through the N atom and the other via the carbonyl O atom. Thermal decomposition of the complexes was studied in inert atmosphere and thermal analysis data (TG and DTA) indicated multi-step decompositions of the metal complexes decomposed in a single stage. The thermal decomposition products were estimated as metal oxides. Finally, the structural properties of all complexes were investigated through quantum chemical computations. © 2024 Elsevier B.V.Scientific and Technological Research Application and Research CenterSinop ÜniversitesiOndokuz Mayis Üniversites

    Bu çalışmada eğitim örgütlerinde eğitim sürecine ilişkin değişim ihtiyacının nedenlerinin öğretmen görüşlerine göre incelenmesi amaçlanmaktadır. Araştırma nitel araştırma yoluyla olgu bilim deseni temel alınarak yapılmıştır. Araştırma grubu 2023-2024 eğitim –öğretim yılında ilk, orta ve lise dereceli okullarda görev yapmakta olan öğretmenlerdir. Araştırmaya katılan 12 öğretmen amaçlı örneklem yöntemi çerçevesinde benzeşik örneklem tekniği ile belirlenmiştir. Araştırmacı tarafından veri toplama aracı olarak 8 sorudan oluşan görüşme formu kullanılmıştır. Elde edilen verilerin analiz edilmesinde verilerin sistemli bir biçimde sebep-sonuç ilişkileri temel alınarak ortaya konulmasını sağlayan betimsel analiz tekniğinden faydalanılmıştır. Elde dilen veriler satır okuma tekniği kullanılarak çözümlenmiştir. Araştırma bulguları analiz edildiğinde eğitim örgütlerinde değişim ihtiyacının nedenleri olarak teknolojinin hızlı gelişimi, öğrenci ilgi ve beklentilerinin günden güne değişmesi, öğretmenlerin mesleki gelişime olan ihtiyaçlarının artması, öğretim yöntemlerinin teknolojik gelişmeler ve öğrenci beklentileri oranında değişmesi, ders araç-gereçlerinin değişimi ortaya konmuştur. Ayrıca eğitim örgütlerinde değişim konusunda gerekli tedbirlerin ertelenmeden zamanında alınması, okul yönetimlerinin bu ihtiyaç dahilinde planlamalarını yapmaları, risk alarak ve konfor alanlarından uzaklaşarak öğrenme alanına geçen kurumların gelişim sağlamaları gerekliliği tespit edilmiştir. Hizmet içi eğitimlerin öğretmenler ve okul yönetimlerince belirli rutinlerde alınması, güncel gelişmelerden ve yeni dinamiklerden kurumların haberdar edilmesi ve alınan eğitimlerin sonucu olarak üretim sağlanması gerekliliği tespit edilmiştir. Ayrıca kurumların kendi ihtiyaçları dahilinde çözümler ortaya koyması için ekip olarak çalışması ve kurumlarda bulunan stratejik plan ve proje yürütme komisyonlarının aktif hale getirilmesi değişim için ön koşul olarak görülmektedir.This study aims to examine the reasons for the need for change regarding the educational process in educational organizations according to teachers' opinions. It was conducted through qualitative research based on the phenomenological pattern. The research group is teachers working in primary, secondary and high school schools in the 2023-2024 academic year. The 12 teachers who participated in the research were determined using the affine sampling technique within the framework of the purposeful sampling method. An interview form consisting of 8 questions was used by the researcher as a data collection tool. In analyzing the obtained data, the descriptive analysis technique was used, which allows the data to be systematically presented based on cause-effect relationships. The obtained data were analyzed using the line reading technique. The rapid development of technology, changing student interests and expectations day by day, increasing needs of teachers for professional development, changing teaching methods in proportion to technological developments and student expectations, and change in course equipment are revealed as the reasons for the need for change in educational organizations. In addition, it has been determined that the necessary measures regarding change in educational organizations must be taken in a timely manner without delay, school administrations must make their plans within this need, and institutions that move to the field of learning by taking risks and moving away from their comfort zones must ensure development. It has been determined that in-service training should be received by teachers and school administrations in certain routines, institutions should be informed about current developments and new dynamics, and production should be provided as a result of the training received. Also, institutions working as a team to come up with solutions within their own needs and activating the strategic plan and project execution commissions in institutions are seen as prerequisites for change

    Bu çalışmanın amacı sınıf öğretmenlerinin uzaktan eğitime yönelik tutumları empatik eğilimleri ve iletişim becerileri arasındaki ilişkinin incelenmesidir. Nicel araştırma yöntemlerinden ilişkisel tarama araştırma modeli kullanılmıştır. Çalışma Malatya ilinde görev yapan 266 sınıf öğretmeniyle yürütülmüş olup (145 erkek, 121 kadın) katılımcılara uzaktan eğitime yönelik tutumları, iletişim becerileri ve empatik eğilimleri ölçekleri uygulanmıştır. Verilerin analizi için araştırma sorularına uygun olarak bağımsız örneklem t testi, tek yönlü varyans analizi (ANOVA), Pearson korelasyon ve basit regresyon analizleri kullanılmıştır. Katılımcıların uzaktan eğitime yönelik tutumlarının orta düzeyde, empatik eğilimleri ve iletişim becerilerinin ise yüksek düzeyde olduğu sonucuna ulaşılmıştır. Ayrıca erkek sınıf öğretmenlerinin empatik eğilim puanlarının, kadın öğretmenlere göre daha düşük çıktığı ve erkek sınıf öğretmenlerinin uzaktan eğitime yönelik tutum puanlarının, kadın sınıf öğretmenlerine göre anlamlı düzeyde yüksek olduğu sonucuna ulaşılmıştır. Sınıf öğretmenlerinin uzaktan eğitime yönelik tutum ile empatik eğilim arasında negatif yönde düşük düzeyde, uzaktan eğitime yönelik tutum ile iletişim becerilerinde de negatif yönde düşük düzeyde ilişki bulunmuş olup; empatik eğilim ile iletişim becerileri arasında pozitif yönlü orta düzeyde ilişki bulunmuştur. Empatik eğilimin uzaktan eğitime yönelik olan tutumu anlamlı düzeyde yordadığı fakat iletişim becerilerinin uzaktan eğitime yönelik tutumu anlamlı düzeyde yordamadığı görülmüştür. Araştırma sonuçları doğrultusunda benzer çalışmaların nitel araştırma desenleri kullanılarak yapılması, araştırmanın sadece sınıf öğretmenleriyle sınırlı tutulmayarak diğer branş öğretmenleri, öğrenci ve velileri de kapsayacak şekilde yapılması önerilebilir.The purpose of this study was to examine the relationship between classroom teachers' attitudes toward distance education, their empathic tendencies and communication skills. Correlational survey model, one of the quantitative research methods, was used as the method of the study. For this purpose, the scales of classroom teachers' attitudes towards distance education, communication skills and empathic tendencies were applied to 266 classroom teachers (145 male, 121 female) working in Malatya province. Independent sample t test, one-way analysis of variance (ANOVA), Pearson correlation and simple regression analyzes were used to analyze the data in accordance with the research questions. As a result of the analysis, it was concluded that the participants' attitudes towards distance education were at a medium level, and their empathic tendencies and communication skills were at a high level. In addition, it was concluded that the empathic tendency scores of male classroom teachers were lower than those of female teachers and that the attitude scores of male classroom teachers towards distance education were significantly higher than those of female classroom teachers. It was determined that there was a negative low- level significant relationship between the attitudes of the classroom teachers participating in the study towards distance education and their empathic tendencies, and a negative low-level significant relationship between distance education and communication skills. It was found that there was a positive and moderately significant relationship between empathic tendency and communication skills. It was seen that empathic tendency predicted the attitude towards distance education at a significant level, but communication skills did not predict the attitude towards distance education at a significant level. In this research, it is suggested that qualitative research design can be included in this research and the research can be carried out more comprehensively by conducting the research not only with classroom teachers

    No full text
    Background Revealing motivations in food choice and investigating the potential role of sustainable healthy eating behavior, ecological footprint awareness and food security in food choice are important points for a sustainable life. This study was conducted with 5285 adults aged 19-65 residing in Turkey to investigate their food choice motivations in terms of sustainable and healthy eating behavior, ecological footprint awareness, and the food insecurity perspective. Methods In this context, the Food Choice Questionnaire, the Sustainable and Healthy Eating Behaviors Scale, the Awareness Scale for Reducing Ecological Footprint and the Household Food Insecurity Access Scale were used. Pearson correlation analysis was used to examine relationships between scales. The effects of sustainable and healthy eating behaviors, ecological footprint awareness, and household food insecurity on food choice motivations were examined via path analysis. Results A moderate positive (r = 0.47, p < 0.05) relationship was found between the participants' awareness levels of sustainable and healthy eating behaviors and reducing the ecological footprint. A weak negative (r=-0.22, p < 0.05) relationship was found between their awareness levels of ecological footprint reduction and household food insecurity, and a weak negative (r=-0.16, p < 0.05) relationship was found between sustainable and healthy eating behaviors and household food insecurity. The explanatory power of ecological footprint awareness, sustainable and healthy eating behaviors, and household food insecurity for food choices was 27.2%. It was observed that ecological footprint awareness (beta = 0.21, p < 0.05) and sustainable and healthy eating behaviors (beta = 0.38, p < 0.05) significantly and positively affected food choices. Conclusions The variables influencing food choices the most were sustainable and healthy eating behavior, ecological footprint awareness, and household food insecurity. Although there are various data in the literature on the multiple factors that determine food choices, a consensus on the effectiveness of these factors has yet to be reached. A comprehensive examination of this issue, including all the components, is needed

    The lands of the Ottoman Empire were occupied by the Entente army after the Armistice of Mondros. The people, who did not react sufficiently to these occupations at the beginning, blew away the cobwebs with the occupation of Izmir and uprisings were started in many parts of the country. In this process, Gazi Mustafa Kemal led those who started the uprising. However, the country was worn out by years of external and internal wars. Poverty, desertions and economic problems made it difficult for the National Struggle to succeed. The leaders of the National Struggle did not consider only hard power sufficient to overcome these problems. The number of deserters in the army, which was the means to use this hard power, had reached three hundred thousand. In order to find a solution to this problem in the first place, they established the Courts of Independence as a deterrent force. The Courts of Independence had two phases. In the first phase, the incidents of bribery to evade military service in the Independence Courts of Al-Jazeera, one of the fourteen Independence Courts, will be discussed. The aim of this study is to address the difficulties experienced during the National Struggle and to reveal the extent of the bribery incidents in the Al Jazeera Independence Court. Methodologically, this article was written by utilizing many academic publications and archival documents.Mondros Mütarekesinden sonra Osmanlı Devleti’nin toprakları İtilaf ordusu tarafından işgal edildi. Başlangıçta bu işgallere yeterince tepki vermeyen halk, İzmir’in işgal edilmesiyle ölü toprağını üstünden attı ve yurdun pek çok yerinde ayaklanma başlatıldı. Bu proseste Gazi Mustafa Kemal ayaklanma başlatanlara önderlik yaptı. Ancak ülke yıllarca dışarıda ve içeride verilen savaşların etkisiyle yıprandı. Yoksulluk, asker kaçakları ve ekonomik sorunlar Milli Mücadele’nin başarıya ulaşmasını zorladı. Milli Mücadele önderleri bu sorunları aşabilmenin yolu olarak sadece sert gücü yeterli görmediler. Bu sert gücü kullanabilmenin aracı olan ordu da asker kaçakları üç yüz bini bulmuştu. Öncelikli olarak bu soruna çare bulabilmek için caydırıcı bir güç olan İstiklâl Mahkemelerini kurdular. İstiklâl Mahkemeleri’nin iki evresi var. Ben birinci evrede kurulan on dört İstiklal Mahkemesinden biri olan ElCezire İstiklâl Mahkemelerinde askerden kaçmak için yaşanan rüşvet olaylarını ele alacağım. Çalışmadaki amacım Milli Mücadele verilirken yaşanan zorluklara değinebilmek ve ElCezire İstiklâl Mahkemesinde yaşanan rüşvet olaylarının boyutunu ortaya koyabilmektir. Yöntemsel olarak ise pek çok akademik yayın ve arşiv belgelerinden faydalanarak makalemi kaleme aldım

    Türk Demokrasisine Adanan Bir Ömür: Ali Naili Erdem

    No full text
    In Turkish political history, there has been a clash between two groups since the 1st Parliament when the foundations of the Republic were laid. The first is: ‘secularist-positivist republicans’ and the second “conservative-republicans”. The concept of ‘Second Republicanism’, which has entered our political literature, was also produced through this dichotomy. Intellectuals such as Peyami Safa, Ziya Gökalp, Prof. Dr. Mehmet Kaplan, Prof. Dr. Vasfi Raşit Sevük and Cemil Meriç were the ideologues of conservative-republicans. Ali Naili Erdem, an important politician who served as the Minister of Labour, the Minister of Industry and the Minister of National Education, followed in the footsteps of these thinkers in the dichotomy between the two groups at the founding of the Republic and took the side of the ‘conservative-republicans’. Ali Naili Erdem is an important political figure who took part in the political scene in the most critical periods of Turkish political history. This study focuses on the life and ideas of Ali Naili Erdem. As a method, an interview lasting one hour and fifteen minutes was conducted by asking him about the topics that were not included in the book ‘Siyasetin Yollarında’ in which Erdem wrote his own biography. In addition, the Minutes of the Grand National Assembly of Turkey were utilised in relation to the political developments of the period. The aim of the study is to introduce a person like Ali Naili Erdem, who served as a minister in the most complex periods of our political history, to a new generation of readers. Keywords:Türk Demokrasisine Adanan Bir Ömür: Ali Naili Erdem Türk siyasal tarihinde Cumhuriyet’in temellerinin atıldığı 1. Meclis’ten bu yana iki grubun çatışması yaşanmıştır. Birincisi: “laisist-pozitivist cumhuriyetçiler”, ikincisi ise “muhafazakâr-cumhuriyetçiler”. Siyasi literatürümüze giren “İkinci Cumhuriyetçilik” kavramı da bu dikotomi üzerinden üretilmiştir. Peyami Safa, Ziya Gökalp, Prof. Dr. Mehmet Kaplan, Prof. Dr. Vasfi Raşit Sevük ve Cemil Meriç gibi aydınlar muhafazakâr-cumhuriyetçilerin ideologluğunu yapmıştır. Çalışma Bakanlığı, Sanayi Bakanlığı ve Milli Eğitim Bakanlığı görevlerinde bulunmuş önemli bir siyasetçi olan Ali Naili Erdem ise Cumhuriyetin kuruluşunda iki grup arasındaki dikotomide bu düşünürlerin izinden giderek “muhafazakâr-cumhuriyetçilerin” safında yer almıştır. Ali Naili Erdem, Türk siyasal tarihinin en kritik dönemlerinde siyaset sahnesinde yer almış önemli bir siyasi figürdür. Çalışmada Ali Naili Erdem’in hayatı ve fikirleri üzerinde durulmuştur. Yöntem olarak Erdem’in kendi biyografisini yazdığı “Siyasetin Yollarında” kitabında yer almayan konular kendisine sorularak bir saat on beş dakika süren mülakat gerçekleştirilmiştir. Ayrıca dönemin siyasi gelişmeleri ile ilgili olarak TBMM Zabıt Ceridelerinden faydalanılmıştır. Çalışmanın hedefi ise Ali Naili Erdem gibi siyasi tarihimizin en karmaşık dönemlerinde bakanlıklar yapmış birini yeni nesil okuyucu ile tanıştırabilmektir

    THE EFFECTS OF OUTDOOR ADVERTISING, WALL ADS AND BILLBOARDS ON CONTEMPORARY ART IN URBAN CULTURE

    No full text
    In today's consumption culture, one of the various ways to reach people is through visual communication tools such as outdoor advertising, wall ads, and billboards. These communication tools, intended for informing people, contribute to contemporary art as an aesthetic and visual language through human -induced changes, natural effects, and deformations. The transformation of outdoor advertising, wall ads, and billboards into artistic phenomena within urban culture is highlighted by artists, also with an emphasis on the characteristics of the eras they lived in, aiming to create awareness in subsequent artists' social consciousness. Beyond plastic and aesthetic experiences, artists have dealt with these elements, which are visual images of daily life, with an emphasis on waste materials in urban culture. Again, the fact that artists make references to issues such as environmental awareness from a different perspective, culture, art, politics, economy, consumerism, and social awareness of the period they deal with makes the research important. This study specifically focuses on urban culture and aims to address the quest What are the effects of outdoor advertising, wall ads, and billboards on contemporary art? with an emphasis on urban culture. In this study, conducted through a descriptive scanning method, the obtained data has been compiled through document analysis. The conclusion drawn is that artists, in their works, make references to urban culture beyond conventional plastic values and establish an archive of urban culture

    Evidence-Based Individual Psychology Practice: Adlerian Pattern Focused Therapy

    No full text
    Adlerian Pattern-Focused Therapy is an evidence-based practice based on Individual Psychology. This paper explores the therapy's definition, historical development, the specific processes involved in the therapeutic sessions, and how case conceptualization is approached. Central to this therapy is its goal to transform maladaptive behavioral and cognitive patterns into healthier, adaptive ones. The structured approach encompasses a series of 10 sessions, focusing primarily on the strategy of pattern replacement. Tools like the Patient Health Questionnaire–9, Outcome Rating Scale, and Session Rating Scale play a pivotal role in these counseling sessions, providing measurable outcomes and feedback. While Adlerian Pattern-Focused Therapy has gained notable traction in contemporary mental health discourse, its widespread adoption remains limited within Türkiye. Nevertheless, its evidence-based foundation and pragmatic application render it a promising avenue for enhancing mental health services, not only in Türkiye but also across global contexts. By providing information about this therapy, this study may contribute to its implementation and execution within the scope of mental health services
