Authors: Bektaş Bilgiç Eylem
Published: December 2024

Hemodynamic parameters are clinical indicators used in Human and Veterinary Medicine to assess the general health status of patients and identify potential risks. Alpha–2 adrenoceptor agonists, such as Medetomidine and Dexmedetomidine, are known to produce dose–dependent premedication ranging from mild to profound and have significant cardiovascular effects. This study aimed to evaluate the effects of these commonly used alpha–2 adrenoceptor agonists on hemodynamic parameters, particularly blood pressure. To achieve this, 100 cats aged between 6 months and 7 years old ere randomly divided into two groups. Hemodynamic parameters were analyzed both before and 5 minutes after premedication with either Medetomidine or Dexmedetomidine. Although there were significant changes in hemodynamic parameters before and after premedication within each group, no statistically significant differences were observed between the Medetomidine and Dexmedetomidine groups. In conclusion, the effects of equivalent doses of Medetomidine and Dexmedetomidine on hemodynamic parameters were found to be similar in cats.

Water is a primary necessity, but access to clean water remains limited, particularly in remote coastal regions of Indonesia. Therefore, a community empowerment initiative that implemented a brackish water purification device utilizing local materials (ALPAMAL) in Kedung Pandan Village, Jabon, Sidoarjo, through a service-learning approach. The program aimed to enhance the quality of life by facilitating access to clean water for daily household use, where brackish water is purified into potable water via ALPAMAL. The methodology commenced with surveys and observational studies to assess community conditions, followed by the assembly and installation of the ALPAMAL unit. Subsequently, a post-activity inauguration and resident survey were conducted. The results indicated that prior to ALPAMAL installation, it was characterized by high salinity, notable turbidity, and viscous consistency, rendering washing practices ineffective. Following the utilization of ALPAMAL, approximately 50% of respondents noted that the water was no longer sticky, while the remaining 50% reported that laundry became cleaner. All community partners perceived a notable transformation post-installation, with access to clean, sufficient water now available to meet daily requirements.

Abstract: Satellite cells, the resident muscle stem cells, play a crucial role in skeletal muscle regeneration, growth, and repair. Asymmetric cell division is a critical process regulating satellite cell self-renewal and differentiation, and is governed by various intrinsic and extrinsic factors. Key biomarkers of satellite cell characteristics, such as Pax7, MRFs, and Sprouty1, are essential in maintaining satellite cell homeostasis. Signaling pathways, including Notch, Wnt, TGF-β, FGF2, and the PAR complex, intricately regulate satellite cell division and fate determination. Asymmetric division is orchestrated through the establishment of cell polarity and differential distribution of fate determinants. Aging and diseases like Duchenne muscular dystrophy disrupt asymmetric division, leading to impaired satellite cell function and muscle regeneration. Potential therapeutic strategies aim to rejuvenate satellite cells and promote muscle regeneration by targeting the gut microbiome, utilizing gene editing technologies, and harnessing the power of exercise-induced factors. Understanding the molecular mechanisms governing satellite cell behavior and Keywords should be in lowercase and separated by semicolons. Developing innovative therapies hold promise for combating age-related muscle deterioration and pathological conditions characterized due to impaired muscle regeneration. Future research should focus on unraveling the complex regulatory networks and translating findings into effective clinical applications to restore muscle function.

This paper proposes to evaluate how different machine learning techniques can be used to predict daytime power generation based on the Daily Power Generation Data data set. As a result of six models, which contain Random Forest Regressor, Decision Tree Regressor, Nearest Neighbors, Linear Regression, MLP Regressor, and SVR, a clear understanding has been accomplished by assessing the performance using multiple metrics. First, the Random Forest Regressor turned out to be the best in terms of the Mean Squared Error (MSE) of 3.57E-06, which was the lowest among the three ML models. The introduction of the paper highlights the role of precise planning of the power market and the consecutive sections describing the topic mathematically. The table below, with a total list of performance issues, explains why the Random Forest Regressor is the superior full-proof model using the lowest MSE, highest explained variance, and great resistance to outlying samples. The paper thus gave various useful approval criteria that we can largely choose the best model out of them because the Random Forest Regressor was able to get the highest performance metrics.

Heart attacks, or myocardial infarctions, are a primary cause of mortality worldwide, underscoring the importance of early and accurate diagnosis to improve patient outcomes. This paper reviews various Artificial Intelligence (AI) and Machine Learning (ML) techniques for heart attack diagnosis, focusing on both traditional algorithms and more complex models. The traditional algorithms are Support Vector Machine (SVM), K-Nearest Neighbors (KNN), Logistic Regression (LR), and Decision Trees (DT). More complex models are Convolutional Neural Networks (CNN), Extreme Gradient Boosting (XGBoost), Auto-encoders, Artificial Neural Networks (ANN), and TSK Fuzzy Inference System (TANFIS). Additionally, the integration of optimization techniques, including the Grey Wolf Optimizer (GWO), Particle Swarm Optimization (PSO), and Jellyfish Optimization Algorithm (JOA) is explored to enhance model accuracy by selecting the most important features. Our findings indicate that ensemble and hybrid models, which combine ML with metaheuristic optimization, show significant potential in improving diagnostic performance and reducing overfitting. However, challenges remain, particularly regarding computational complexity and interpretability. This study provides insights into the strengths and limitations of different AI-based diagnostic models, contributing to the advancement of automated heart disease prediction systems.
Advances in Machine Learning for Predicting and Detecting Influenza Outbreaks: A Review
Authors:   Department of Chemistry and Biochemistry, University of Arkansas, Fayetteville, AR 72701, USA, Ehsan Ehsan
Published: December 2024

Influenza is often associated with millions of cases and hundreds of thousands of deaths each year, thus constituting a serious threat to public health. Traditional surveillance techniques employed in epidemiology are limited in forecasting impending outbreaks as caused by delays in receiving the relevant information and the dynamic nature of political environments. This review focuses on the available literature on the use of machine learning (ML) techniques in understanding and controlling influenza with an accent on all the sources of information available, including clinical papers, social networking sites and others. Applicable practices in classifying predictive modeling techniques, including deep learning and others, ensemble techniques, time series analysis, etc., have increased the speed and precision of the earlier results. Even so, the achievements made so far have not come on a silver platter as there are challenges, but not limited to data issues, model explain ability and strict validation processes. Some research areas are enhancing the present models to accommodate diverse virulent strains of the viruses and advancing extensive data analysis methods. It is noted in this review that machine learning strategies are essential in combating health issues and, thus, why such technologies can be deployed within a concise duration in the context of influenza epidemics for effective forecasting and resource management to salvage lives.

In this paper, we undertake the intriguing task of uniting the advanced methods in the domain of decision making. It is about the fusion of plithogenic logic and neutrosophic HPA. It appears that in an environment where the nature of strategic decisions includes high levels of uncertainty and complexity, it is a time to seek more comprehensive methods that help in overcoming contradictions and ambiguities. This is not the first time efforts have been made to bridge the divide between decision making and artificial intelligence, but for some reason, a holistic approach to these tools is still absent. What is missing from the current literature is a framework that would tackle the two challenges of the decision-making processes, and that chaos of human judgments which is often the order of the day. To this end, we seek to articulate the missing literature, suggesting a methodology that may be useful in addressing these problems. The purpose of this model is to integrate plithogenic logic, which in its nature is a model that enables the integration of varied perspectives, and neutrosophic HPA that is theorized to be in tune with uncertainty and those fundamental contradictions in expert judgment. When this combined methodology is implemented, it seems that the outcomes achieved not only enhance the value of decision analysis, but they also allow for a more versatile and elaborate framework for evaluation of alternatives in seemingly ambiguous contexts. The truth is that the contribution of this study could be rather considerable. Theoretically, it may expand the way decision making is perceived. And more practically, it provides a way which can be more useful and comprehensible, particularly in the fields of business strategic management, policy formulation and implementation, and even project management.
Visibilización del proceso de gentrificación acaecido en el centro histórico de Santiago de Cali, Valle del Cauca, Colombia
Authors: Bolaños Benavides Juan Esteban , Cardona Olaya Félix Augusto
Published: December 2024

Este proyecto surge como reflexión sobre el proyecto PD-0320: Modelo de interacción mediado por la narrativa de memoria intergeneracional dentro una comunidad del semillero LUMEN del programa de Diseño Visual, que establece una relación entre el diseño, la memoria y el reencantamiento social sobre la herencia patrimonial cultural con respecto a las tecnologías que la hacen posible y el contexto que la vive. Se centró en el proceso de urbanización “Ciudad Paraíso” que se enmarca en la agenda Distrito Especial Cali 2030 sobre una de las zonas más emblemáticas de perímetro urbano como es el barrio El Calvario, mediante un proceso de gentrificación radical que invisibiliza gran parte de la memoria colectiva de la comunidad habitante mostrando sólo aspectos negativos, lo que ha creado estigmas y percepciones negativas, que aunque no se pueden negar, no son los únicos, ni los más significativos, puesto que allí se han formado familias por dos o más generaciones y han surgido emprendimientos deportivos, culturales y empresariales, también personajes que han aportado mucho a la cultura e identidad caleña. Por ello, desde el diseño visual se emprendió una táctica para visibilizar que este proceso de gentrificación, ya impajaritable, debe reconocer que existen otras memorias y por ello, se desarrolló un proceso de investigación/creación desde un enfoque cualitativo de corte etnográfico con participación de la comunidad a través del colectivo 8 LETRAS para el diseño y divulgación de manifestaciones de la memoria colectiva afirmativa mediante un sistema audiovisual dentro del propio contexto de actuación y protagonizado por sus habitantes.
Reflexiones sobre la Relación entre la Percepción Mediática y la Construcción de Paz
Authors: Martinez Barco Joan Sebastián
Published: December 2024

Este trabajo reflexiona sobre las formas en que el ejercicio del poder, anteriormente limitado al control territorial y ahora extendido al control de la información, viene influyendo en la percepción pública del desempeño de los mecanismos para la construcción de paz y la no repetición propuesta en el acuerdo final en 2016. Se revisó por qué los acuerdos significaron una alteración de las dinámicas de poder en Colombia, y cómo esto desencadenó campañas de desinformación y estigmatización de los acuerdos, con el objetivo de socavar el apoyo popular a los esfuerzos de construcción de paz. Además, se propone que el mayor obstáculo representado por la manipulación de la opinión pública es el impacto potencial en el proyecto de vida de las personas implicadas, debido al alcance y la difusión de información que les ataca y estigmatiza. Finalmente, se reconoce la importancia de comprender el papel de los medios de comunicación y el acceso a la información para la construcción de una visión crítica en los consumidores de contenido, además de la prevención de distorsiones en los ejercicios contemporáneos y futuros de pacificación y construcción de país.

Published: December 2024

This study investigates the gap between General English Teachers' (GETs) assumed ability to teach English for Medical Purposes (EMP) and their mismatched qualifications in Saudi Arabia. It explores the underdevelopment of the EMP sector, where GETs often lack proper training and resources. The research employs a qualitative case study approach, utilizing semi-structured interviews and open-ended surveys. The participants include three medical professors (MPs), five experienced EMP teachers (EMP Ts), and twenty-one GETs. The focus is on uncovering the pedagogical needs for GETs to teach EMP effectively. The findings reveal a significant discrepancy between assumed competence, preparedness and actual performance of GETs. This highlights the need for professional development programs focusing on the pedagogy of ESP and EMP, along with curriculum and instructional design, to equip GETs with the necessary skills and knowledge for successful EMP instruction. The findings also highlight the need for curriculum revision and improved needs assessment. By identifying these needs, the research aims to contribute to improved EMP teaching in Saudi Arabia. This study will assist policymakers and educators in creating a more effective system, for preparing future healthcare professionals with the essential English language skills required for success.

Published: December 2024

Introduction:

Whether the kinematics of cadaveric knees recreate those of the patient's knees after total knee arthroplasty (TKA) remains unknown. This study compared in vivo and in vitro fluoroscopic kinematics of knees after TKA during knee bending using the same implant design.

Methods:

Patients who had undergone cruciate-retaining and cruciate-substituting total knee arthroplasty (CR-TKA and CS-TKA) did squatting motions. Fresh-frozen human cadaveric knees were tested under dynamic closed-chain knee extension in an Oxford knee rig. Fluoroscopic kinematics were measured in vivo and in vitro using a 2-dimensional to 3-dimensional registration technique. The axial rotation angle and anterior-posterior translation of medial and lateral contact points of the femoral implant relative to the tibial implant was evaluated in each flexion angle.

Results:

No notable differences in the axial rotation angles were found between in vivo and in vitro measurements in both CR-TKA and CS-TKA. In early flexion, the medial and lateral contact points in cadaver knees were located more posterior than those in in vivo after CR-TKA. From early flexion to high flexion, the medial and lateral contact points in cadaver knees were located more posterior than those in in vivo after CS-TKA.

Conclusions:

The axial rotation angle of cadaveric knees in the Oxford knee rig was similar to that measured in vivo after TKA. However, the anterior-posterior location of the femoral implant in cadaver knee was more posterior than that in in vivo knees after TKA.
Predictors of Internal Rotation–Dependent Activities of Daily Living Performance and Favorable Satisfaction Despite Loss of Objective Internal Rotation After Reverse Shoulder Arthroplasty

Introduction:

Previous research has determined that objective and subjective internal rotation (IR) may be discordant. The purpose of this study was to identify predictors of patient-reported ability to perform IR-dependent activities of daily living (IRADLs) and favorable patient satisfaction after reverse shoulder arthroplasty (RSA) despite the loss of objective IR.

Methods:

A single, institutional, shoulder arthroplasty database was queried for patients undergoing primary RSA with a minimum 2-year follow-up. Patients who were wheelchair bound or had a preoperative diagnosis of infection, fracture, or tumor were excluded. We first identified patients in the overall cohort that lost objective IR from pre- to postoperative assessment, defined as a one-point reduction in the eight-point Flurin scale. In this cohort, we identified patient characteristics that were predictive of patient-reported ability to perform IRADLs and overall patient satisfaction and thresholds in postoperative objective IR.

Results:

Out of 599 RSAs initially identified, 107 RSAs lost objective IR (45% female, mean age 70 years). On average, patients lost 1.7 IR score points pre- to postoperatively. Greater preoperative IR and lesser loss of objective IR pre- to postoperatively were associated with greater patient-reported ability to perform all 4 IRADLs (odds ratio 1.54 to 2.5), whereas female sex was associated with worse patient-reported ability to perform 3 IRADLs (odds ratio 0.26 to 0.36). We identified that patients with postoperative IR below the sacrum were unlikely to be able to perform IRADLs and those with postoperative IR at or above L4-L5 were likely to be satisfied.

Conclusion:

Despite losing objectively assessed IR after RSA, many patients are still able to perform IRADLs and report favorable satisfaction as long as objective IR reaches L4/5. Female sex and postoperative IR below the sacrum were associated with the inability to perform IRADLs, whereas postoperative IR to or above L4-L5 was associated with subjective ratings of satisfaction.

Authors: Saad Younis  , Mardeya Emayof
Published: December 2024

Computed tomography (CT) has emerged as a highly accurate and the most effective technique for detecting and diagnosing various types of cancer. It also aids in evaluating the cancer's stage, size, and form. CT has become the mainstay for cancer detection in Libya, where cost and accessibility are the primary factors determining the modality for diagnostic purposes. The study aims to evaluate the role of CT by correlating the CT scan results with histological findings and determining its sensitivity and specificity in diagnosing various cancers. The study was conducted on 144 patients who underwent CT scans between January 2023 and March 2024. The age range of 31–40 years had the highest percentage of cases, with 39 (27.08%). A CT scan showed 98.52% sensitivity and 87.50% specificity, demonstrating high accuracy in identifying malignant and benign cases. The precision and accuracy of CT scans were 99.25% and 97.91%, respectively. This study demonstrates that CT is highly sensitive in detecting cancers, making diagnoses, and particularly in identifying its morphology and type, estimating whether it is benign or malignant, and identifying any other associated findings with high sensitivity and specificity.

Published: December 2024

This study aims to examine the effectiveness of the Project-Based Learning (PjBL) model in improving student collaboration skills in the Research Statistics course. Collaboration is defined as the ability to work harmoniously in a group to achieve a common goal. In the context of higher education, this skill is important to support students' readiness to face the world of work that demands the ability to work in a team. The research uses a quantitative descriptive approach, with data obtained through questionnaires and observation sheets. The measurement was carried out based on five dimensions of collaboration: effective communication, teamwork, division of tasks, joint problem-solving, and mutual respect. The research sample consisted of 22 students in the V semester, who were selected using the total sampling technique. Data analysis was carried out descriptively to calculate the average score of each dimension and its category based on a scale. The findings indicate that the PjBL model positively impacts students' collaboration skills, with significant improvements in the dimensions of mutual respect and teamwork (categorized as Very Good). However, the task distribution dimension requires further attention due to gaps in group responsibilities. These findings confirm that PjBL is effective in bridging the gap between academic competencies and workforce demands, while also recommending the integration of active learning in higher education

Recurrent respiratory tract infections (RRTIs) have a complex pathogenic mechanism. There may be correlations between expression levels of serum 25-hydroxy-vitamin D (25-OH-D), regulatory T cells (Tregs), total immu-noglobulin E (IgE) and RRTIs. We aimed to explore the correlations of serum 25-OH-D, cluster of differentiation 4 (CD4)+CD25+CD127- Tregs and total IgE in children with RRTIs. A total of 150 children with pneumonia were enrolled as the subjects and randomly assigned into a control group (97 children with non-RRTIs) and an observation group (53 children with RRTIs). The expression levels of serum 25-OH-D, CD4+CD25+CD127- Tregs and total IgE were compared in RRTI children with different genders, stages, sites of lesions and severities of illness. The correlation was tested by Pearson analysis. The expression level of serum 25-OH-D was significantly higher in children with RRTIs in the upper respiratory tract than that in the lower respiratory tract, whereas the expression level of total IgE was significantly lower in children with RRTIs in the upper re-spiratory tract (p<0.05). The expression level of 25-OH-D was negatively corre-lated with expression levels of CD4+CD25+CD127- Tregs and total IgE (r=-0.355, -0.314, p<0.05), while a positive correlation was found between expression levels of CD4+CD25+CD127- Treg and total IgE (r=0.237, p<0.05). The area under the curve of combination of 25-OH-D, CD4+CD25+CD127- Treg and total IgE expres-sion levels for predicting RRTIs was 0.852. The combined detection of the three indicators is conducive to enhancing the detection rate of RRTIs.

Thrombi formed in blood vessels, although typically experienc-ing normal blood flow, may undergo mineral deposition, resulting in the forma-tion of phleboliths. When affecting the oral region, they can lead to facial asym-metry due to volume increase, imparting a bluish appearance to the mucosa. Despite phlebolith diagnosis often being incidental, distinguishing them from other calcifications becomes imperative. This article presents two pertinent clinical cases: the first associated with a traumatic event clinically diagnosed as a probable sialolith, and the second case, initially identified as a phlebolith, showed no association with vascular pathology. These cases underscore the im-portance of considering the presence of phleboliths in the differential diagnosis of vascular lesions and other calcifications in the oral region. Furthermore, it highlights the necessity for a meticulous approach and detailed assessment to determine the origin and nature of calcifications in the oral mucosa to ensure appropriate treatment and mitigate potential complications.
Моделі споживчої поведінки в туризмі
Authors: Алдошина М. В.
Published: December 2024

У статті розглядаються моделі споживчої поведінки які описують процес прийняття рішень щодо споживання туристичних послуг на різних етапах. Зазначено що споживання туристичних послуг відноситься до складної або невпевненої споживчої поведінки, яка визначається високим рівнем ризиків в процесі вибору серед альтернативних варіантів та потребує ретельної підготовки та залучення більшої кількості учасників. Серед особливостей споживчої поведінки зазначені наступні відмінні характеристики: цілеспрямованість дій споживача; свобода вибору щодо обробки комунікаційних повідомлень рекламного характеру та надання зворотного зв’язку; послідовність взаємопов’язаних етапів; можливість впливу на споживача та зміну намірів щодо альтернативних варіантів вибору на різних етапах. Визначено що моделі споживчої поведінки в туризмі на сучасному етапі приділяють особливу увагу стадіям: підготовки, пошуку та оцінці післякупівельного споживання. Стадія споживчого пошуку та підготовки може тривати від одного до трьох місяців в залежності від різних умов та видів подорожі. Такий тривалий період підкреслює важливість інформаційного та рекламного забезпечення споживачів за усіма комунікаційними каналами туристичного підприємства або дестинації. В результаті аналізу моделей визначено чотири групи факторів впливу на споживчі рішення в туризмі: зовнішні та внутрішні фактори, характер запланованої подорожі та післякупівельна оцінка отриманих вражень. Систематизація факторів надає змогу виробникам туристичних послуг більш точно визначити ціннісні характеристики пропозиції та забезпечувати високий рівень клієнтоорієнованості. Зазначено, що як внутрішні соціальні фактори, такі як стадія життєвого циклу, соціальний клас, референтні групи та родина, спричиняють значний вплив на поведінку спожива. Так і зовнішні фактори тяжіння, які стосуються загальних характеристик та іміджу дестинацій, суттєво впливають на прийняття остаточного рішення щодо вибору  місця призначення. Визначені особливості поведінки споживачів на туристичному ринку, систематизація факторів впливу та послідовність етапів прийняття рішень забезпечує високу таргетованість налаштувань інструментів маркетингової стратегії просування та сприяє підвищенню рівня конверсії та фактичних продажів.

Agricultural data analytics empowers farmers to
enhance decision-making, forecast market shifts, and address
specific challenges, fostering sustainable farming practices.
This research examines farmers' information needs in Gujarat
by scrutinizing 1.937276 million calls to the Kisan Call
Centre from 2009 to 2024. The analysis tracks call volume
changes over time and their geographic origins, facilitating
district-tailored support planning. Calls are classified by crop
type and query nature, illuminating key farmer concerns.
Seasonal query patterns pinpoint critical periods of heightened
farmer support requirements. The database further classifies
information based on seasonal cycles (Kharif, Jayad, and
Rabi) and sectors (Agriculture, Horticulture, Animal
Husbandry, and Fisheries). These insights enable
policymakers to devise strategies aligned with call types,
locations, and timing. The study underscores how data-driven
approaches can elevate agricultural support systems, boosting
farming efficiency and effectiveness in Gujarat and outside.
The KCC database encompasses a total of 40,774,833 records,
with 1,937,276 pertaining specifically to the state of Gujarat.

Investigation of Mechanical Behavior of Carbon Fiber Reinforced Sandwich Composites with Different Weights
Authors: Şimşir Ercan
Published: December 2024

In this study, the impact and three-point bending performances of sandwich structures produced using carbon fiber-reinforced composite materials and XPS foam core with different fiber weights were investigated. Carbon fiber weighing 200 g/m² and 400 g/m² were used in sandwich structures. The reinforced layers were formed by placing four layers above and four layers below the XPS foam core. For the impact resistance test, low-speed impact tests and three-point bending tests were performed at 30 J, 50 J, and 70 J energy levels. As a result of the tests, it was determined that the increase in fiber weight has a significant effect on the impact resistance and bending strength of the materials. While the samples with a fiber weight of 200 g/m² reached a maximum force value of 1200 N under 30 J energy, the samples with a weight of 400 g/m² reached a force value of 6400 N. Similarly, at energy levels of 50 J and 70 J, heavier fiber samples provided higher maximum force and energy absorption. In three-point bending tests, samples with a fiber weight of 200 g/m² reached a maximum force value of 200 N, while samples with a weight of 400 g/m² reached up to 450 N. As a result, increasing the fiber weight significantly increased the mechanical strength and energy absorption capacity of sandwich structures, indicating that materials are a critical parameter for engineering applications.
