Bartın ve Kastamonu yöresi doğu kayını ormanlarında ağaç bileşenlerine ait karbon yoğunluklarının değişimi
No full textGiriş ve amaçlar Kyoto protokolü gereği taraf ülkeler her yıl ulusal envanter raporlarını Tarım, Ormancılık ve Arazi Kullanımı (AFOLU) kılavuzuna göre hazırlayarak Birleşmiş Milletler İklim Değişikliği Çerçeve Sözleşmesi sekretaryasına sunmaktadır. Ancak daha hassas bildirimlerde bulunmak için ülkelerin kendi ağaç türlerine özgü katsayıları üretmesi gerekmektedir. Bu çalışma, Bartın ve Kastamonu yöresi doğu kayını (Fagus orientalis Lipsky.) ormanlarında ağaç bileşenlerinin karbon yoğunluğu ile toprak üstü ve toplam ağaç kütlesine ait ağırlıklı karbon yoğunluklarını belirlemek amacıyla yapılmıştır. Yöntemler Örneklemeler dört gelişim çağı [a (d1,3<8 cm), b (d1,3=8-19,9 cm), c (d1,3=20-35,9 cm) ve d (d1,3 ?36 cm)] ve her gelişim çağından dört adet olmak üzere toplam 16 alandan yapılmıştır. Örnekleme alanlarının farklı yetişme ortamlarını temsil etmesine özen gösterilmiştir. Öncelikle örnekleme alanlarının yetişme ortamı özellikleri belirlenmiştir. Daha sonra her örnekleme alanında baskın durumda olan üç ağaçtan yaprak, dal, odun, kabuk ve kök örnekleri alınmıştır. Laboratuvarda örnekleme alanlarından alınan ağaç bileşenlerine ait örneklerde karbon analizi yapılmıştır. Elde edilen veriler varyans analizi ve Duncan çoklu karşılaştırma testi ile değerlendirilmiştir. Bulgular Karbon yoğunluğu meşcere gelişim çağları ve ağaç bileşenleri arasında önemli farklılıklar göstermiştir (P<0,05). Karbon yoğunluğu d çağındaki meşcerelerde daha yüksek düzeyde (%50,27) bulunmuştur. Karbon yoğunluğu ağaç bileşenleri arasında en düşük kabukta (%47,99), en yüksek ise yaprakta (%50,50) bulunmuştur. Doğal doğu kayını ormanları için ağırlıklı karbon yoğunluğu toprak üstü ağaç kütlesi için %49,15, toplam ağaç kütlesi için ise %49,27 olarak hesaplanmıştır. Sonuçlar Elde edilen veriler, doğu kayını ormanlarında gerek ağaçlarda gerekse ağaçların farklı bileşenlerinde depolanan karbon stoklarının hesaplanmasında, ölü örtü ayrışma süreçlerinin izlenmesinde ve yönetiminde kullanılabilir
The perceived effect of digital transformation and resultant empowerment on job performance of employees in the fitness family business
No full textPurposeThe impact of technological transformations in all sectors is undeniably significant, especially in fitness family business. The aim is to examine the digital transformation perceptions of fitness centre employees and the effects of perceived empowerment on their job performance in family business in Turkey.Design/methodology/approachThe sample was 334 fitness centre employees. Four variables were evaluated (digital transformation, meaning competence, self-determination and job performance), and PLS-SEM was used.FindingsThe digital transformation process in the fitness sector can be considered as an important factor in terms of creating new business ventures. Our results showed that digital transformation perceived by family business employees had a significantly influence on the meaning competence of the employees. Also, the meaning competence of employees was a mediator between the digital transformation and job performance.Practical implicationsManagers of family businesses must take into account that an appropriate digital transformation of their products and/or services has an impact on the meaning competence of their employees. Thus, through increased competence in employee performance, the digitization of family business fitness will lead to higher employee performance and productivity.Originality/valueThis study innovates by linking digital transformation as a factor influencing the coach's own motivation and self-perceived competence in the use of technology to their job performance.European Union [MCIN/AEI/10.13039/501100011033]We would like to thank all the participants who participated in the study.

Rhodanine-pyridinium derivatives as a new category of cholinesterase inhibitors: Design, synthesis, in vitro and in silico enzymatic evaluations
No full textRhodanine-pyridinium derivatives 10a-q were designed and synthesized based on reported cholinesterase (ChE) inhibitors and evaluated as potent anti-Alzheimer's disease agents. The in vitro anti-ChE activity of the title compounds was evaluated against two main forms of this enzyme: acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). The obtained in vitro results showed that all the synthesized derivatives were more potent than positive control tacrine against AChE. Moreover, most of the new synthesized compounds were more potent than tacrine against BChE. Among the synthesized compounds, compound 10p was the most potent compound against AChE and compound 10f was the most potent compound against BChE. In vitro kinetic study demonstrated that compounds 10p and 10f were competitive inhibitors against AChE and BChE, respectively. Both these compounds had a 4-CF3 substituent on phenyl ring of benzyl pyridinium moiety. Docking study on compounds 10p and 10f demonstrated that these compounds with favorable binding energies in comparison to tacrine attached to the active sites of AChE and BChE. Molecular dynamics simulations were performed on the 10p-AChE and 10f-BChE complexes to gain deeper insights into the behavior of these compounds in the active sites of target enzymes.Tehran University of Medical Sciences [1403-3-221-73931]This work was financially supported by the Tehran University of Medical Sciences with grant number of 1403-3-221-73931

Method: A scoping review was conducted to synthesize empirical studies with various methodologies and findings. This approach allowed for a more comprehensive understanding of simulation practices in public health nursing education and practice. PubMed, Scopus, and Web of Science databases were searched for studies conducted between January 2018 and November 2024. Titles and abstracts were screened, and full-text articles were evaluated based on inclusion and exclusion criteria. Extracted findings were critically analyzed and synthesized into themes. Results: A total of 1,810 articles were retrieved from PubMed, Scopus, and Web of Science. After excluding 1,697 articles that did not meet the inclusion criteria, 113 articles were selected for full-text evaluation, and ultimately, 22 articles met the inclusion criteria. The findings were categorized under three main themes: (1) Simulation and education, (2) Improvement of diagnostic and treatment processes through simulation, and (3) The role of technology in health and social care. The findings indicated that simulation-based practices positively impacted nursing students and nurses by enhancing their communication skills, critical thinking, clinical confidence, empathy, perspective, and reflective thinking. However, challenges like the difficulty in using certain equipment, technical problems, high costs, and supervision and training difficulties were reported. Conclusion: This study examined simulation-based training in public health nursing education and practice. Future studies should address existing challenges an

The Relationship Between Gender Perception, Fertility Awareness, and Reproductive Coercion in Fertile Women
No full textObjective: This study aimed to determine the relationship between gender perception, fertility awareness, and reproductive pressure in women of reproductive age. Method: This cross-sectional study included women of reproductive age in Turkey. There are 22 million women between the ages of 18 and 49 living in Turkey. According to the sampling method with a known universe, 385 samples were obtained. The research was completed in 412 women. The data were collected with the descriptive information form, perception gender scale (PGS), fertility awareness scale (FAS), reproductive coercion scale (RCS). Results: Women's PGS mean score is 104.40 +/- 14.64, their FAS mean score is 64.67 +/- 12.83, and their RCS mean score is 0.08 +/- 0.36. Between PGS and FAS, highly significant, positive, weak (r=0.206, p=0.000); between PGS and RCS, highly significant, negative, very weak (r=-0.193, p=0.000); and between FAS and RCS, a significant, negative, very weak (r=-0.082, p=0.048) relationship was found. Conclusion: Women's gender perceptions were high, fertility awareness was moderate, and reproductive pressures were low. It was determined that as gender perception increased, fertility awareness increased, and reproductive pressure decreased
On duals of certain types of sequence spaces of complex uncertain variable
No full textUncertainty theory has significantly advanced and expanded over the past ten years. In this article, we introduce the notions of uncertain alpha-dual, uncertain beta-dual and uncertain gamma-dual of complex uncertain sequence spaces. Convergence and boundedness of complex uncertain sequences are taken in the sense of almost surely due to B. Liu and then few characterizations of the newly introduced uncertain dual spaces are established. Furthermore, our goal is to propose and establish inclusion relations within these sequence spaces
Yeni Ontolojik Arayışlar ve Nesne Yönelimli Ontoloji: Graham Harman'ın Perspektifi
No full textThis study aims to deal with the new ontological searches that have begun to emerge in the field of philosophy in general terms and, in particular, to reveal how the object-oriented ontology view, which is one of these movements, differs from these movements. For this purpose, first of all, the general outlines of the new materialism, speculative realism, speculative materialism movements, which are called new ontological pursuits, and their differences with classical philosophy will be discussed. Afterward, the object-oriented ontology, which can be considered within these movements, and the views of Graham Harman, who is at the basis of this idea, will be focussed on. While discussing Harman's views, the main focus will be on his conception of the new object, which is claimed to be the main difference that distinguishes him from the other ontological movements mentioned above, and the concept of metaphor he proposes to know this object
Effect of Heat Treatment and Electrochemical Potential on Tribocorrosion Behavior of High-Strength Low-Alloy Ship Mooring Chain Steel
No full textSteels are widely used in the maritime sector and many industries, and are expected to have different mechanical properties and high strength depending on the place of use. In addition to these features, they are also expected to have extraordinary resistance in different environments. One of these environments is the seawater environment, an environments where corrosive effects are pretty high. Equipment used in these environments is expected to be resistant to such conditions. This study examined the tribocorrosion properties of S355J2 + AR steel, whose mechanical properties were changed by two different heat treatments and which is used for fastening ships and different marine equipment in the open sea. It has been observed that the corrosion resistance of Grade 3 chain, which has better mechanical properties, is lower than that of Grade 2 quality steel. In test environments with only mechanical effects, Grade 3 material with high wear resistance was exposed to more wear in the tribocorrosive condition. In cathodic state tests, adhesive wear such as plowing and grooves, which are purely mechanical wear effects, were observed. In the anodic case, corrosion due to anodic dissolution was detected. According to EDS analysis, Cl elements that have a corrosion-enhancing effect on the wear surface were observed for both steel grades.Scientific and Technological Research Council of Turkiye (TUBITAK); Scientific Research Projects Coordination Unit of Bartimath;n University, Turkiye [2023-FEN-CY-001]Open access funding provided by the Scientific and Technological Research Council of Turkiye (TUBITAK).

The effect of gamified e-learning supported teaching on students' computer programming self-efficacy perceptions, attitudes towards programming and classroom engament
No full textBu araştırmanın amacı, oyunlaştırılmış e-öğrenme destekli öğretimin, öğrencilerin bilgisayar programlama öz-yeterlik algıları, programlamaya yönelik tutumları ve derse katılımları üzerindeki etkilerini incelemektir. Araştırma, 2023-2024 eğitim-öğretim yılında Türkiye'nin kuzeybatısında yer alan bir fen lisesinde, 9. sınıfta öğrenim gören iki şubeden toplam 60 gönüllü öğrencinin katılımıyla gerçekleştirilmiştir. Çalışmada, deney grubu öğrencileri hem geleneksel sınıf içi öğretim hem de oyunlaştırılmış e-öğrenme desteği ile öğrenim görürken, kontrol grubu öğrencileri yalnızca geleneksel sınıf içi öğretim almıştır. Karma araştırma yöntemi kullanılan çalışmada, veri toplama araçları olarak nicel veriler için Bilgisayar Programlama Öz-yeterlik Ölçeği, Programlamaya Yönelik Tutum Ölçeği ve Derse Katılım Envanteri; nitel veriler için ise yüz yüze görüşme formu tercih edilmiştir. Gruplar rastgele deney ve kontrol olarak ayrıldıktan sonra, her iki gruba ön testler uygulanmıştır. Çalışma sonunda her iki gruba son testler uygulanmış; deney grubuyla ayrıca yüz yüze görüşmeler gerçekleştirilmiş ve görüşme formu ile detaylı bilgiler toplanmıştır. E-öğrenme ortamı olarak Millî Eğitim Bakanlığı tarafından geliştirilen Eğitim Bilişim Ağı (EBA) kullanılmıştır. Altı hafta süren deney çalışmasından önce, deney grubuna bir hafta boyunca sınıf ortamında oyunlaştırma kurgusu tanıtılmıştır. Deney süresince, EBA üzerinden haftalık etkinlik duyuruları yapılmış; ders materyalleri, izlenmesi gereken videolar ve çözülmesi gereken konu testleri paylaşılmıştır. Öğrencilerin aldıkları puanlara göre haftalık liderlik tahtası oluşturulmuş ve belirlenen şartları sağlayan öğrencilere, araştırmacı tarafından geliştirilen rozetler verilmiştir. Her hafta liderlik tahtasında ilk 10'a giren öğrenciler duyurulmuş, tüm etkinliklerin sonunda ise genel liderlik sıralaması ilan edilerek rozet ve puanlar paylaşılmıştır. Araştırma sonuçlarına göre, oyunlaştırılmış e-öğrenme desteği, öğrencilerin programlamaya yönelik tutumları ve derse katılımları üzerinde istatistiksel olarak anlamlı bir fark yaratmamış; ancak, programlama öz-yeterlik algılarında anlamlı bir artış sağlamıştır. Çalışma, programlama öğretiminde karşılaşılan zorluklara yönelik olarak oyunlaştırılmış e-öğrenme desteğinin etkisini deneysel olarak ortaya koymaktadır. Ayrıca, bu araştırmanın, EBA sistemi içinde farklı derslerin öğretmen kontrolünde oyunlaştırılmasına yönelik bir model sunabileceği düşünülmektedir.The aim of this study is to investigate the effects of gamified e-learning-supported instruction on students' self-efficacy perceptions in computer programming, their attitudes toward programming, and their classroom engagement. The study was conducted during the 2023-2024 academic year in a science high school located in the northwestern region of Turkey, with the participation of 60 voluntary 9th-grade students from two different classes. In the study, students in the experimental group received both traditional classroom instruction and gamified e-learning support, whereas students in the control group were taught solely through traditional classroom instruction. The study employed a mixed-methods research design. Quantitative data were collected using the Computer Programming Self-Efficacy Scale, the Attitudes Toward Programming Scale, and the Classroom Engagement Inventory. Qualitative data were obtained through a face-to-face interview form. After the groups were randomly assigned as experimental and control groups, pre-tests were administered to both groups. At the end of the study, post-tests were applied to both groups, and face-to-face interviews were conducted with the experimental group using the developed interview form. The e-learning platform used in the study was the Education Informatics Network (EBA), developed by the Ministry of National Education in Turkey. Before the six-week experimental phase, the gamification framework was introduced to the experimental group during a one-week, face-to-face session in their classroom. Throughout the experimental phase, weekly activity announcements were made via EBA, along with lesson materials, videos, and topic-based tests for the students to engage with. Weekly leaderboards were created based on the scores obtained by students, and those meeting specific criteria were awarded badges developed by the researcher. Each week, the top 10 students on the leaderboard were announced, and at the end of the study, the top participants across all activities were recognized with badges and points. The results of the study indicate that gamified e-learning support did not lead to statistically significant differences in students' attitudes toward programming or their classroom engagement. However, it significantly improved their self-efficacy in programming. This study demonstrates the experimental effects of gamified e-learning support in addressing challenges faced in programming education. Furthermore, it is suggested that this research could provide a model for gamification in other subjects within the EBA system under teacher supervision
