Improving Pressure Prediction Accuracy for Capacitive Sensors Using Machine Learning Techniques
(International Information and Engineering Technology Association, 2025) Ahmed, Shaymaa Taha; Kamil, Bayda Zahid; Abdulkader, Rasha Mahdi; Kadhim, Qusay Kanaan; Zaki, Rana Mohammed Hassan; Kadhim, Ahmed Kanaan
Capacitive sensors are used in a wide range of industries, including wearable technology, robotics, industrial automation, and healthcare monitoring. Capacitive pressure gauges are a good example, but environmental factors, such as variations in temperature can significantly affect their pressure prediction performance. However, the accuracy of pressure prediction is often affected by ambient variables such as humidity and temperature, and the nonlinear characteristics of the sensor. To solve these problems, this research paper proposes a machine learning-based calibration method for capacitive sensors which would further improve the accuracy of pressure prediction. Special attention was paid to the Support Vector Regression (SVR) strategy, which was deemed the best, primarily due to its ability to accurately simulate sparse data for nonlinear functions requirement for embedded systems. Accordingly, in experimental tests, the hyper parameters of the Radial Basis Function (RBF) core used to construct the RBF model, were optimized to achieve the best results. The proposed SVR model achieved 98% prediction accuracy in experimental results, a significant improvement over traditional linear regression. This approach provides a scalable method for future smart sensors bridging the limitations of field deployment and enabling high-resolution modeling of industrially useful instruments.
To Stay or Leave? Consequences of Ethical Dilemma Experienced by Nurses in the Intensive Care Units
(Springer Science and Business Media B.V., 2025) Kalaycıoğlu, Ozan; Sert Özen, Arzu; Yeşildağ, Ahmet
Global shortages of healthcare workers, particularly nurses, have been exacerbated by the COVID-19 pandemic, putting signifcant pressure on healthcare systems worldwide. According to the International Council of Nurses (ICN), 13 million additional nurses are urgently needed to meet global demand. Nurses, who are the backbone of patient care, have faced unprecedented ethical dilemmas, particularly in intensive care units (ICUs), where resource allocation, such as ventilator management and triage decisions, often confict with basic ethical principles. This study seeks to contribute to the literature by examining the efect of the ethical dilemmas experienced by ICU nurses during COVID-19 pandemic on emotional exhaustion and turnover intention and testing whether emotional exhaustion has a mediating role on the relationship between ethical dilemma and turnover intention. The research model was tested with partial least square structural equation modeling (PLS– SEM) in the package program SmartPLS. The bias-corrected bootstrapping (resampling) method was applied to the sample of 189 nurses who work in the intensive care units in the hospitals in the East Black Sea Region of Türkiye. The research results indicated that ethical dilemma is positively associated with emotional exhaustion (β=0.305, 95% CI [0.167–0.407]), and turnover intention (β=0.156, 95% CI [0.146—0.423]). In addition, emotional exhaustion has a complementary partial mediation efect (B=0.149, 95% CI [0.083–0.215]) between ethical dilemma and turnover intention among ICU nurses.

İstanbul, 2026 Prof. Dr. Zuhal AKMEŞE, Öğr. Gör. Ahmet BİKİÇ FOREWORD Today's media ecosystem is undergoing a process of transformation that is faster, more fragile and more multi-layered than at any other time in history. The spread of digital technologies, the restructuring of communication practices, the rise of artificial intelligence-based content production and the fundamental transformation of forms of cultural representation have not only expanded media studies; they have also made the boundaries between disciplines more permeable. This book consists of chapters that trace the very traces of this pluralistic transformation, examining the interactions between media, art, culture, technology, and politics from different academic perspectives. Each study reveals a unique facet of current media debates while bringing together different methodological approaches such as critical theory, content analysis, discourse analysis, design research, and digital culture studies. The chapter entitled Asymmetry and Surveillance in Digital Communication provides an important introduction to the book's theoretical framework by analysing the culture of digital surveillance that has developed at the intersection of modernisation and postmodern thought. The study Synthetic Media and Deepfake: Artificial Intelligence and Ethical Boundaries in Journalism discusses phenomena such as hyperreality, algorithmic manipulation, and the fragility of truth in the post-truth era, drawing new ethical boundaries for modern journalism. The study titled Managing Political Communication as a Social Network at the Age of Artificial Intelligence reveals that political processes have now evolved into a data-driven, network-based and algorithmically steerable structure. The section Mao's Cult of Personality through Maoist Propaganda in the Chinese Cultural Revolution discusses the media-ideology relationship with historical examples. The study Collective Memory in the Digital Sphere: Pan-Turkist Narratives in YouTube Comments examines the role of social media in the production of collective memory. Representation in Turkish Media: America's New Tax Policies offers an economic-political media framing analysis. The section entitled Creating Contrast and Exclusion Strategies in News Narrative Structure reveals the representation of migration in news discourse through discourse analysis. The study entitled Adolescence Series Analysis within the Framework of the Manosphere Concept discusses digital masculinity cultures and the reflections of toxic masculinity in popular culture. The section Representations of the Family from the Perspective of Plastic Arts and New Media in the Context of Digitalisation examines the transformation of the concept of family in art and digital culture. An Examination of Product Packaging Designs in the Context of Visual Communication strengthens the book's artistic focus by revealing the relationship between graphic design, consumer perception and visual culture. This book demonstrates that media and art studies can only be understood through their intertwined structure of social, cultural, political, and technological dynamics, rather than through disciplinary distinctions. Each chapter offers a unique focus that expands media research; when read together, they reveal the multi-layered structure of the contemporary media environment from a holistic perspective. We would like to express our sincere gratitude to the Chairman of the Board of Trustees of Istanbul Gelisim University, Mr. Abdulkadir Gayretli, the Rector Prof. Dr. Bahri Şahin, the Head of the Department of Public Relations and Promotion, Mr. Bülent Değirmenci, and all staff members who contributed to the realisation of this project.

The effect of Kangaroo care on vital signs in infants undergoing cardiac surgery: A randomized controlled study
(W. B. Saunders, 2025) Cengizli, Dilara; Albayrak, Selvinaz
Background and purpose: This study aimed to determine the effect of kangaroo care on vital signs in infants undergoing cardiac surgery. Design and methods: This randomized controlled study was conducted in the pediatrics cardiovascular surgery intensive care unit of a training research hospital between December 2023 and March 2024. The sample consisted of 60 infants who had undergone cardiac surgery, with 30 assigned to the experimental group and 30 to the control group. The experimental group received kangaroo care during the procedure. Data was collected via the Descriptive Information Form about sample characteristics and the Vital Signs and Pain Recording Form. The data were analyzed using descriptive statistics, Chi-square, independent sample t-tests, ANOVA, and mixed effect model variance analysis. The study was recorded in the Clinicaltrials.gov PRS system. Results: The mixed-method comparison showed a high level of significance in the intervention group regarding heart rate and respiratory rate reductions, pain score reduction, and increased peripheral saturation levels in both time and group measurements (p < 0.001). Additionally, the decrease in systolic blood pressure in the intervention group was significant in the group measurements (p < 0.001), whereas time-based comparisons showed no significant changes in diastolic blood pressure (p > 0.05). Comparison of changes in pre-test and post-test vital signs between the intervention and control groups were significant, except for diastolic blood pressure (p < 0.05). Conclusions: The study demonstrated that post-surgical kangaroo care in infants undergoing cardiac surgery reduced heart rate, systolic arterial pressure, and respiratory rate, while increasing peripheral saturation levels and decreasing pain scores. Implications for practice: The integration of kangaroo care into post-cardiac surgery care practices may lead to improvements in infants' vital signs and promote relaxation through mother-infant skin-to-skin contact. This, in turn, could potentially enhance family-centered care practices in cardiac surgery units, and, in the future, improve the quality of care outcomes for both mothers and infants. © 2025 Elsevier Inc.

Do Technological Advances Promote Ecological Sustainability? Evidence from Panel Causality Analysis for the Dirtiest and Cleanest Countries
(Springer, 2025) Çelik, Ali; Yılmaz, Ebru Gül; Kahveci, Şükran; Yılmaz, Gonca
As a solution to the problem of scarce resources, which stands out in the commonly accepted defnition of the economy, technology assumes the role of humanity’s savior in terms of the efcient use of resources. On the other hand, much research points to the negative efects of technology, such as air pollution and climate change. The motivation of the study is to measure the net efect, considering both the negative and positive efects of technology. Does technology give more to humanity than it takes from humanity? In light of this, the primary question that will be investigated in this study is as follows: What are the efects of technology, which is one of the fundamental components of economic growth, on environmental pollution in countries that have high and low levels of pollution? This approach addresses a gap in the existing literature. To investigate the answer to this question, we use the moment quantile regression (MMQR) method proposed by Machado and Silva (2019) and panel causality tests with cross-sectional dependence and heterogeneity for the most and least carbon emitting countries. The results of the causality tests show that there is a bidirectional causality relationship between total factor productivity (TFP) and Gross Domestic Product (GDP) per capita for the most polluting countries, while there is a unidirectional causality relationship from GDP per capita to TFP for the least polluting countries. Conversely, the same structure applies to the relationship between TFP and CO2 per capita. Consequently, although there are limitations in calculating the monetary value of technology’s negative externalities, it is clear that technology has both losses and gains. It is recommended that a legal infrastructure be established by a supranational authority to prevent negative externalities such as pollution.
