No full textBu çalışmanın amacı eğitimcilerin bakış açılarından bir gerçeklik olarak akran zorbalığının nedenleri ve sonuçlarını derinlemesine inceleyerek bu sorunlara olası çözüm yolları ortaya koymaktır. İlgili çalışma nitel araştırma desenlerinden olgu bilim deseniyle düzenlenmiştir. Araştırmanın çalışma grubu kartopu (zincirleme) örneklem tekniğiyle belirlenmiş 16 eğitimciden oluşmaktadır. Araştırmada yarı yapılandırılmış görüşme tekniği kullanılmış; elde edilen veriler betimsel analiz tekniği ile çözümlenmiştir. Buna göre katılımcılar zorbalık kavramını; baskı, kaba güç kullanımı, istenmeyen olumsuz davranışlar, güç dengesizliği, manipüle etme, utandırma, dışlamak, alaycı yaklaşım ve rekabet şeklinde ifade etmişlerdir. Katılımcılar akran zorbalığının nedenlerini; yanlış anne-baba tutumu, sosyal medya ve televizyon kullanımı, arkadaş etkisi, öğrencinin kişisel kaynaklı nedenleri, yanlış öğretmen tutumu, ekonomik nedenler ve okul yönetiminin yaklaşımı şeklinde ifade etmişlerdir. Katılımcılar akran zorbalığının sonuçlarını; psikolojik sonuçlar, sosyolojik sonuçlar, okul başarısı, okul sevgisi ve ekonomik sonuçlar şeklinde ifade etmişlerdir. Katılımcılar akran zorbalığının üstesinden gelinmesi için yapılması gerekenleri; aile, okul rehberlik servisi, sosyal medya ve televizyon, öğretmen, okul yönetimi ve Millî Eğitim Bakanlığı ve Milli Eğitim Müdürlüğü şeklinde birtakım önerilerden bulunmuşlardır. Bu çalışma zorbalık ve akran zorbalığı kavramlarını açıklayarak okul yöneticilerine, öğretmenlere, ailelere ve öğrencilere bilgi veriyor olması bakımından önemlidir. Bu önemler doğrultusunda eğitim-öğretim sürecini olumsuz etkileyen zorbalık konusunda araştırmanın, sorunların ortaya çıkmasında ve sorunlara çözüm bulunmasında rol oynayacağı, ilerde yapılacak olan çalışmalara yol gösterici olabileceği ve literatürde ilgili alanda bulunan eksikleri kapatabileceği düşünülmektedir.The aim of this study is to examine the causes and consequences of peer bullying as a reality from the perspectives of educators and to suggest possible solutions to these problems. This study was organized with a case study design, one of the qualitative research designs. The study group of the research consists of 16 educators determined by snowball (chain) sampling technique. Semi-structured interview technique was used in the study and the data obtained were analyzed with descriptive analysis technique. Accordingly, the participants defined the concept of bullying as pressure, use of brute force, unwanted negative behaviors, power imbalance, manipulation, shaming, exclusion, sarcasm and competition. Participants stated the causes of peer bullying as wrong parental attitude, use of social media and television, peer influence, personal reasons of the student, wrong teacher attitude, economic reasons and the approach of the school administration. Participants expressed the consequences of peer bullying as psychological consequences, sociological consequences, school success, love for school and economic consequences. Participants suggested some things to be done to overcome peer bullying: family, school guidance service, social media and television, teachers, school administration, Ministry of National Education and Directorate of National Education. This study is important in terms of providing information to school administrators, teachers, parents and students by explaining the concepts of bullying and peer bullying. In line with these importance, it is thought that the research on bullying, which negatively affects the education process, will play a role in the emergence of problems and finding solutions to problems, can be a guide for future studies and can fill the gaps in the literature in the related field
The role of Healthy Life Centres in delivering weight management: A retrospective study
No full textIntroduction: Healthy Life Centres (HLCs) in Turkey were established as primary health services to promote healthier lifestyle behaviours, aiming to reduce obesity and diseases linked to physical inactivity. This study aimed to investigate the weight management programme delivered by one HLC and to track the participants' progress in terms of weight loss and adherence to the program. Methods: This was a retrospective study. Participants consisted of adults aged >= 18 who attended the HLC for weight management from Sept 2017-June 2020. Data including attendance, age, gender, height and body weight were collected and analysed at 3, 6, 12-month time-points. Missing data were interpreted using last observed weight carried forward analysis (LOCF). Results: Over a two-year period 2652 adults (88% female) consulted the nutrition counselling service, of whom 43% attended once. Mean age of those attending once was 40.2 (12.35) years and age increased significantly with adherence. Baseline body mass index (BMI) was 31.4 (6.32) kg/m2. For those attending at the different time-points, weight loss was 4.4 % of initial body weight at 3-months (n = 841), 8.6 % of initial body weight at 6month (n = 237), and 11.8 % initial body weight at 12-month follow-up (n = 56). LOCF analysis revealed a significant time effect for change in percentage body weight for the data collected at 6 and 12 months. Conclusion: This programme was successful in reaching clinically meaningful weight loss at 3, 6, 12-month for the participants who committed to the weight management programme. However, there was a substantial decline in participant engagement, with only a 2 % attendance rate at 12 months. Furthermore, it is noteworthy that nearly half of the clients attended only one session during the study period. The findings of the current study can be used to inform policy makers about the strengths and weaknesses of HLCs

Comparison of the effects of axillary brachial plexus block, inhalation anesthesia, and total intravenous anesthesia on tourniquet-induced ischemia-reperfusion injury in upper extremity surgery
No full textBACKGROUND: Post-ischemia reperfusion can lead to oxidative stress and an increase in oxidative markers. Employing preventive strategies and antioxidant agents may help mitigate ischemia-reperfusion injury (IRI). The use of a tourniquet in extremity surgery has been associated with IRI. This study aims to investigate the impact of three different approaches- brachial plexus block, total intravenous anesthesia (TIVA), and inhalation anesthesia-on IRI during upper extremity surgery using a tourniquet. METHODS: Patients aged 18 to 45 with American Society of Anesthesiologists (ASA) I -II scores were randomly assigned to one of three groups: Group A received an axillary block with bupivacaine; Group I underwent inhalation anesthesia with sevoflurane; and Group T received TIVA with propofol and remifentanil infusion. Blood samples were collected to measure glucose, lactate, total antioxidant status (TAS), total oxidant status (TOS), and ischemia-modified albumin (IMA) levels at various time points: before anesthesia (t1), 1 minute before tourniquet release (t2), 20 minutes after tourniquet release (t3), and 4 hours after tourniquet release (t4). RESULTS: In Group I, lactate levels at t3, and glucose levels at t2 and t3, were higher compared to the other groups. Group A exhibited lower IMA levels at t2, t3, and t4 than the other groups. Additionally, Group I had lower IMA levels at t2, t3, and t4 compared to Group T. TAS levels were higher in Group I at t2, t3, and t4 compared to the other groups. TOS levels at t2 and t3 were lower in Group A than in Group I. CONCLUSION: Axillary anesthesia results in a sympathetic block, promoting better perfusion of the upper extremity. This study demonstrated lower levels of oxidative stress markers with axillary plexus block. Therefore, these results suggest that the axillary block has the potential to mitigate IRI
A reliability generalization study of the STEM-CIS scale: Exploring moderator effects
No full textA reliability generalization (RG) study is crucial for assessing and improving scale reliability across contexts, guiding future research, and ensuring valid results. Therefore, our study aim was to conduct an RG of the STEM (Science, Technology, Engineering, and Mathematics) Career Interest Scale (STEM-CIS) to assess its reliability across contexts and explore factors influencing reliability. Assuming a random-effects model, we found a strong reliability coefficient of.92 (95% CI [.91,.93]) for the STEM-CIS by analyzing data from 39 studies using the transformed reliability coefficient values from Bonett's formula. Both the overall scale and its subscales (Science, Technology, Engineering, and Mathematics) demonstrated substantial heterogeneity, indicating variability in internal consistency across studies. ANOVA and meta-regression analyses were conducted to investigate variability of Cronbach's alpha estimates. Results showed the most important moderators were sample size, language, country, test version (original or adapted scale), and school level. The final predictive model consisted of these important moderators. Results showed these five moderators significantly affected variation of Cronbach's alpha values. Despite notable heterogeneity found among the STEM-CIS subscales, the scale demonstrated satisfactory reliability overall. Researchers should report reliability metrics from their specific datasets to ensure accurate interpretation and application of the scale in varying contexts
C-supplement submodules
No full textBu tez çalışmasında cr-tümlenmiş modüller tanımlandı. Ñ modül ve S,Y≤Ñ alt modüller olsun. Ñ=S+Y ve S∩Y parçalanan ise Y ye S nin Ñ de c-tümleyeni denir. Ñ 'nin her alt modülü c-tümleyene sahip olursa Ñ ye cr-tümlenmiş modül adı verilir. Bir Ñ modülünün cr-tümlenmiş olması için gerek ve yeter koşul Ñ⁄C(Ñ) 'in yarı basit olmasıdır. Modülleri cr-tümlenmiş olan halkalar karakterize edildi. Bununla birlikte cr-tümlenmiş modüllerin direkt toplamlar, alt modüller homomorfik görüntüler ve toplamlar altında kapalı olduğu gösterildi.In this study, cr-supplemented modules are introduced. Let Ñ module and S,Y≤Ñ be submodules. A module Ñ is cr-supplemented if, for each submodule S of Ñ, there is a submodule Y in Ñ such that Ñ=S+Y and S∩Y is crumbling. If each submodule of Ñ has c-supplement then Ñ is called cr-supplemented. Ñ is cr-supplemented if and only if ( Ñ)⁄(C(Ñ)) is semisimple. We provide characterization of rings for which their modules are cr-supplemented. With this, we show that cr-supplemented modules are closed under direct sums, submodules, homomorphic images and sums

No full textIntroduction While the Thrombite device differs from the Solitare stent with its Helical open-side structure feature, it shows great similarity with its other features. We assessed the Thrombite device's effectiveness and safety in this study.Materials and methods The study was a retrospective analysis of patients who were included in the Turkish Interventional Neurology database and who had mechanical thrombectomy with the Thrombite device as the first choice between January 2020 and January 2023. The type of study is descriptive research.Result Using the Thrombite thrombectomy device, 525 patients received treatment. The median baseline National Institutes of Health Stroke Scale (NIHSS) score was 13, the median initial Alberta Stroke Program Early Computed Tomography (ASPECT) score was 8, and the mean patient age was 68.6+11.7 years. Between the groin puncture and the successful recanalization, the median time was 34 minutes (interquartile range [IQR]: 15-45). 48.2% (modified treatment in cerebral infarction; mTICI) 2b/3% and 33.9% (mTICI 2c/3) were the first-pass recanalization rates. In the end, 87.7% of patients had effective recanalization (thrombolysis in cerebral infarction 2b/3). In the first-pass subgroup, the favorable functional result (modified Rankin Scale 0-2) was 51.8%, while it was 41.6% for the entire patient population. The rate of embolization into new territory/different territory were 2.1/0.1%. 23 patients (4.5%) had symptomatic hemorrhage.Conclusion The Thrombite device showed a good safety profile and high overall successful recanalization rates in our experience
COVID-19 Pandemisinin Babalık Rolüne Yansımaları: Bir Karma Yöntem Araştırması
No full textAmaç: Bu araştırmada babaların babalık algılarını ve COVID-19 sürecindeki deneyimlerini tanımlamak ve derinlemesine incelemek amaçlanmıştır. Yöntem: Yakınsayan Paralel Desende planlanan araştırmada niceliksel veriler Babalık Rolü Algı Ölçeği (BRAÖ) ve Erkek Rolleri Ölçeği (ERÖ); niteliksel veriler Yarı Yapılandırılmış Görüşme Formu kullanılarak, Nisan-Haziran 2023 tarihleri arasında çevrimiçi olarak elde edilmiştir. Nicel verilerin analizinde tanımlayıcı istatiksel yöntemler, nitel veriler için tematik analiz kullanılmıştır. Bulgular: Babaların, BRAÖ ve ERÖ puan ortalamalarının sırasıyla 107,60±7,64 ve 3,85±0,76 olduğu görüldü. Nitel analiz sonucunda, babaların babalık algıları ve COVID-19 sürecindeki deneyimleri olmak üzere 2 temaya ulaşılmıştır. Babaların bu süreçteki deneyimleri, COVID-19’un yansımalarını ve zayıf/güçlü hissedilen durumları kapsamaktadır. Sonuç: Babaların geleneksel babalık rollerinin yanında öznel bir babalık deneyimlerinin olduğu görülmektedir. Pandemi döneminde babaların çocuk bakımı ve ev işi yapmada almış oldukları sorumlulukta artış olsa da bu durum babaların var olan hegemonik erkeklik deneyimlerini yeniden ürettikleri ve eril toplumsal düzende sürdürmeye devam ettiklerini düşündürmektedir
Investigation of optimal machining Monel 400 superalloy considering carbon emissions using FEM, regression and ANN methods
No full textIn this study, the optimal machining parameters for the machining of Monel 400 superalloy considering carbon emission were investigated. Monel 400 stands out among nickel alloys with its resistance to high corrosive environments. First, the Johnson-Cook material model for Monel 400 was developed for FEM simulations. Then, FEM simulations were performed using seven different machining parameters, including cutting and geometric, and validated with experimental results in the literature. The obtained FEM results were trained and predicted by regression and Artificial Neural Network (ANN) analysis. With this study, the Johnson-Cook material model of Monel 400 superalloy and the optimal machining parameters considering carbon emission with different cutting and geometric machining parameters are provided to the literature. As a result, it was determined that the most effective machining parameters in terms of cutting force were 139.04% increase in depth of cut, 74.23% increase in feed and 9.57% decrease in side rake angle. In terms of carbon emission, the most effective machining parameters were found to be -338.9g reduction in depth of cut, -294.3g reduction in feed rate and -171.9g reduction in cutting speed. In terms of training and prediction of FEM results, it was observed that the regression model was 89.19% for cutting force data and 95.39% for carbon emission, while the ANN model was 98.081% for cutting force data and 99.978% for carbon emission. Optimal machining parameters were determined by ANN method. The optimal machining parameters (cutting speed, feed, cutting depth, side rake angle, back rake angle, lead angle and nose radius) of Monel 400 superalloy with the lowest cutting force and carbon emission were determined as 100 m/min, 0.15mm/rev, 0.375 mm, 0 degrees, 5 degrees, 0 degrees, 0 degrees, 0 degrees, 0.4 mm and 100 m/min, 0.2mm/rev, 0.25 mm, -5 degrees, 5 degrees, 0 degrees, 0.8 mm, respectively
A Refinement of Schwarz’s Lemma at the Boundary
No full textWe study a boundary version of the Schwarz lemma for analytic functions. In addition, an analytic function satisfying the equality case is found by deducing inequalities connected with the modulus of the derivative of analytic functions at a boundary point of the unit disk. In these inequalities, we consider some coefficients used in the Taylor expansion of the function. In the last theorem, by analyzing the Taylor expansion about two points, we obtain the modulus of the derivative of the function at point 1. © Springer Science+Business Media, LLC, part of Springer Nature 2024
