The Effect of Stress Ball Utilization on Dyspnea Severity and Anxiety Level in Patients Receiving Nebulizer Therapy: Randomized Controlled Study
No full textAim: The study primarily aimed at examining the effect of stress ball utilization on dyspnea and anxiety during nebulizer therapy. The secondary aim was to determine the effect of stress ball utilization on the duration of therapy and vital signs. Methods: The study has a randomized controlled experimental design. The study population consisted of inpatients receiving nebulizer therapy. A total of 80 patients, 40 in the intervention group and 40 in the control group, were included in the sample. The study was conducted between October 2023 and March 2024. Patients in the intervention group were asked to use a stress ball during nebulizer therapy. Data were collected using a Patient Information Form, the Visual Analog Scale, and the State-Trait Anxiety Inventory. Descriptive statistics, Chi-square, paired test, and one sample t-test were used in data analysis. Results: The mean age of the patients was 65 years and over and 78% of them had COPD. Stress ball utilization caused a significant effect on the severity of dyspnea (intervention: t = 2.862, p 0.05). Conclusions: Utilization of a stress ball during nebulizer therapy has a positive effect on reducing anxiety levels and prolonging the duration of nebulizer use.

Artificial Synaptic Device and Chaotic Oscillator Implementation Using a Novel Floating Memtranstor Emulator
No full textThe memtranstor is a memory element that establishes a direct relationship between charge and magnetic flux through nonlinear magnetic effects and is classified as the fourth memory element after the memristor, memcapacitor, and meminductor. This paper discusses the design of a floating emulator integrating a newly introduced memory element called memtranstor. The proposed memtranstor circuit employs four differential voltage current conveyors (DVCCs), one analog multiplier, three grounded capacitors, and four grounded resistors. The PSPICE simulation results are done using the 0.18-mu m CMOS technology parameter to confirm the functionality of the suggested floating emulator circuit. By altering the parameters in the models, a variety of simulations are done including memory effect simulations, Monte Carlo simulations, pinched hysteresis loops using various DC control voltages and frequencies, temperature variation, and output voltage noise simulations. To demonstrate the potential applications of the proposed memtranstor, its artificial synaptic plasticity and its role in a memtranstor-based chaotic oscillator are validated through example simulations
The Development of Digital Twin Baby Incubators for Fault Detection and Performance Analysis
No full textThis study focuses on developing a digital twin for baby incubators in neonatal intensive care units to enhance monitoring and care for premature infants. The digital twin employs a hybrid model integrating Long Short-Term Memory (LSTM) and Random Forest (RF) algorithms to predict potential errors and alarms. The LSTM algorithm was trained using sensor data provided by a health technology company to predict future measurements. Subsequently, the RF algorithm classifies these predictions into specific error conditions. The hybrid model demonstrates success with mean squared error and mean absolute error values of 1540533.6 and 160.8 for the LSTM model and an 86.44% accuracy rate for the RF model. The study's key findings emphasize the effectiveness of the hybrid model in predicting future sensor values and classifying errors, representing a significant step towards improving premature baby care. Integrating LSTM and RF algorithms offers an innovative approach to error prediction, minimizing risks and improving premature infant health outcomes. In summary, this study successfully develops a digital twin for baby incubators, offering a promising solution for advancing newborn healthcare services and providing a foundation for future research. © 2025 Elsevier B.V., All rights reserved
Batı Anadolu Kabuk Deformasyon Modellemesi: GPS ve Depremsellik Verilerine Dayalı Bir Değerlendirme
No full textBatı Anadolu, farklı tektonik rejimlerin ve deformasyon süreçlerinin etkisi altında bulunan karmaşık bir bölgedir. Bu çalışma, GPS verileri ve depremsellik analizlerini entegre ederek bölgenin deformasyon dinamiklerini detaylı bir şekilde incelemektedir. Çalışmada, Kuzey Anadolu Fay Zonu (KAFZ) boyunca ölçülen yüksek efektif gerinim oranlarının (~140 ngerinim/yıl) sıkışmalı rejimi yansıttığı, buna karşın Ege genişleme bölgesindeki pozitif dilatasyon oranlarının (+50 ngerinim/yıl) genişlemeli rejimin baskın olduğunu gösterdiği tespit edilmiştir. Bu bulgular, çalışmanın temel amacı olan Batı Anadolu’nun aktif tektonik yapısını belirleme ve bölgedeki sismotektonik riskleri değerlendirme hedefine doğrudan katkıda bulunmaktadır. Deprem analizleri, büyük depremlerin bölgesel deformasyon üzerindeki etkisini anlamak için kritik veriler sağlamış; Marmara Denizi doğusunda sıkışmalı, batısında ise genişlemeli rejimlerin hâkim olduğu belirlenmiştir. GPS hız vektörleri ve dilatasyon haritaları, enerji birikimi ve kabuk incelmesi süreçlerinin mekânsal dağılımını ayrıntılı olarak ortaya koymuştur. Bu sonuçlar, yüksek sismik risk taşıyan bölgelerin belirlenmesine ve risk azaltma stratejilerinin geliştirilmesine bilimsel bir temel oluşturmaktadır. Batı Anadolu'nun deformasyon süreçleri üzerine yapılan bu analizler, bölgesel sismik tehlikelerin azaltılması için kritik bir zemin sunmaktadır

The connection between sociology and health is certain. Health sociology also deals with people and health, social causes and consequences of diseases. Physicians who deal with people's health are bound by professional responsibility while providing health services, and are under a duty of care towards the patient while performing their duties. Physicians who do not comply with the duty of care may face various legal consequences. The legal responsibility of the physician can be addressed under two headings. Compensation liability and criminal liability. Compensation liability comes into play when the physician causes material or moral damage to the patient as a result of a faulty procedure or treatment; criminal liability covers situations where the physician commits a crime intentionally or negligently. The article discusses the scope of the physician's legal responsibility, the legal responsibilities that the physician encounters while performing his/her duty, and professional ethical principles. Situations that reduce or eliminate the physician's responsibility are analyzed. The physician's responsibility arising from acting without authority and the conditions of this responsibility will be discussed. Whether or not liability arises if the physician exceeds the limit of acting without authority will be answered
An explainable risk classification model by integrating fuzzy multiple criteria sorting and fuzzy linguistic summarization
No full textThis study proposes a novel explainable risk assessment framework that integrates the fuzzy Full Consistency Method (FUCOM), fuzzy VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR)-Sort, and fuzzy linguistic summarization to address the challenges of uncertainty, prioritization, and interpretability in risk evaluation. The model enables multi-criteria analysis under linguistic uncertainty, classifies risks into predefined categories, and generates human-readable linguistic summaries to support decision-makers. The proposed methodology is applied to a real-world construction case involving 32 risk items, which are categorized into high, medium, and low risk groups. Comparative analysis with six established multiple criteria sorting algorithms reveals strong alignment in classification outcomes. The novelty of the proposed model lies in enhancing the explainability of multiple criteria sorting algorithms by integrating fuzzy linguistic summarization into the classification process-an aspect largely overlooked in the existing literature. The results demonstrate that the proposed model not only produces consistent risk classifications across alternative methods but also enhances decision-makers' understanding through interpretable linguistic outputs
A PROPAGATION STUDY OF XBEE P2P LINKS FOR SHORT-RANGE IOT APPLICATIONS IN OUTDOOR ENVIRONMENTS AT 868 MHZ
No full textThis study presents a preliminary propagation analysis for short-range point-to-point (P2P) wireless communication employing XBee modules operating at the 868 MHz in outdoor environments. In order to facilitate straightforward planning and deployment of XBee P2P links in the context of short-range Internet of Things (IoT) applications, empirical measurements were conducted under line-of-sight (LOS) conditions in urban, suburban, and rural environments. The performance of five well-known empirical path loss models, including Free Space Path Loss (FSPL), Two-Ray Ground Reflection, Log-distance, Hata-Okumura, and Cost231-Hata, was then evaluated based on Received Signal Strength Indicator (RSSI) data. The findings indicate that the FSPL model demonstrates the highest level of accuracy in rural areas, while the Log-distance model exhibits better performance in urban and suburban contexts. In contrast, the Two-Ray and Cost231-Hata models demonstrate a comparatively limited degree of agreement with the measured data across all environments. It is expected that these findings may offer valuable insights for the simple deployment of energy-efficient and cost-effective XBee-based P2P networks in outdoor IoT settings
(Avrupa İnsan Hakları Mahkemesi Kararları Işığında) Toplu Geri Gönderme Yasağı Kapsamında “Geri İtme (Push Back)” Uygulamalarına İlişkin Bir Değerlendirme
No full textDüzensiz göçle mücadele günümüzde birçok devletin göç politikalarının merkezi haline gelmiştir. Bu doğrultuda, mültecilerin geçmeye çalıştıkları ülke sınırına ya da ülkenin kara suları ile uluslararası sulara geri gönderilmeleri şeklindeki uygulamalar sıklıkla kullanılmaktadır. “Geri itme (push-back)” olarak nitelendirilen söz konusu uygulamalar başvurucuların bireysel durumlarının değerlendirilmesine engel teşkil etmekte ve Avrupa İnsan Hakları Sözleşmesine Ek 4 No.lu Protokolün 4. maddesinde düzenlenen “yabancıların topluca sınır dışı edilmeleri yasağının” ihlâli sonucunu doğurabilmektedir. Çalışmamızda geri itme uygulamaları, Avrupa İnsan Hakları Mahkemesinin “yabancıların topluca sınır dışı edilmeleri yasağına” ilişkin kararları ışığında ele alınmaktadır. Çalışmamızda öncelikle söz konusu yasağın “toplu halde geri gönderme” ve “başvurucuya ilişkin objektif ve makûl bireysel inceleme yapılmamış olması” unsurları ele alınmaktadır. Çalışmada daha sonra “bireysel inceleme eksikliğinin başvurucuya izafe edilebilecek bir kusurdan kaynaklanmamış olması şartı”, Avrupa İnsan Hakları Mahkemesinin bu konuda dönüm noktası niteliğinde kabul edilen NT ve ND v. İspanya kararı ve benzer kararlar ışığında eleştirel bir yaklaşımla ele alınmaktadı
Fertility Problems in Breast Cancer Survivorship: Special Focus on Younger Breast Cancer Survivors
No full textWomen diagnosed with breast cancer at a young age (15-39) are a unique population in terms of both the biology of cancer and the way they experience their cancer journey. This age range covers most of the reproductive period when the major events in a woman’s life occur. Due to advances in diagnosis and treatment, breast cancer survival rates have increased in recent years. However, especially chemotherapy and radiotherapy treatments may result in primary ovarian insufficiency/hypoestrogenism and genitourinary syndrome of menopause. There are several options available for younger breast cancer survivors who are concerned about preserving their fertility. Fertility preservation through procedures such as oocyte/embryo cryopreservation. Are common options before the treatment of breast cancer. Another option is ovarian tissue preservation, where part of the ovary is removed and frozen for potential re-implantation in the future. Health professionals need to discuss fertility preservation options with younger breast cancer patients before treatment. © 2025 Elsevier B.V., All rights reserved
Post-Traumatic Growth in Adults in Turkiye and Peru After Devastating Earthquakes at Different Times: A Cross-Cultural Study
No full textThe study aimed to assess post-traumatic growth (PTG) levels among adult earthquake survivors from Turkiye (Kahramanmara & scedil;, 2023) and Peru (Pisco, 2007), who experienced earthquakes at different points in time, and to investigate the impact of sociodemographic and earthquake-related factors on PTG. In the descriptive cross-cultural study, data were collected online using the snowball sampling method through the Individual Information Form and the Post-Posttraumatic Growth Inventory-Expanded (PTGI-X) from a total of 749 survivors participating (388 from Turkiye and 361 from Peru). According to one-way ANCOVA, survivors of the Peru earthquake exhibited higher PTG levels (79.91 +/- 23.74) with a small effect size (eta(2) < 0.017) compared to survivors of the T & uuml;rkiye earthquake (74.23 +/- 26.48), potentially due to the longer time elapsed since the traumatic event (p < .05). After adjusting for the country variable, two-way ANCOVA results revealed that those injured by the earthquake and those who had a different traumatic experience(s) after the earthquake had higher PTGI-X scores
