Throughout a Wireless Sensor Network (WSN), information collected from the environment is continuously transmitted from one node to the next, and then the main collector or server receives and processes it. With the growth of a network, data transfers within the network also grow dramatically. Medical images increase traffic on a network if they are transmitted. An interlayer transmission protocol (WSN) was developed for this study. Pixels are used to create the medical image using the protocol. A gray-level medical image with 512x512 pixels provided by Brain was used to conduct the study. Medical image size is reduced from 256 KB to 192 KB, providing a 25% advantage. A study found SSIM of 51, 1365 and PSNR of 0,9976 for the structural similarity ratio (SSIM). The Advanced Encryption Standard (AES) encryption algorithm safeguards data during the transfer. By creating such a layer, transmissions became safer. In the WSNs, 12.5% and 25% of the data transfer has been reduced based on the information obtained from the study without changing the medical image.

The collected information from the environment in WSN continuously sends from one node to another until it reaches the main collector or server, where processing is done. The transferred data volume will be greater when the network grows. Medical images will also contribute to network traffic. To alleviate this challenge, this research has developed an interlayer transmission protocol for WSNs. This protocol uses the construction of medical images with pixel-based data. In the analysis, a gray-scale medical image 512x512 in size, provided by Brain, is utilized. The image was compressed by the protocol from 256 KB to 192 KB with a percentage of 25%. As a result, the structural similarity index measure showed the SSIM at 51.1365, while the PSNR is at 0.9976; therefore, the quality of the medical image remains unchanged. The protocol uses the AES encryption method for strong data protection to improve security during transmission. Results show that this protocol reduces data transmission in WSNs by 12.5 to 25% without affecting the integrity of the medical image, which is indicative of the efficiency of the protocol in enhancing network performance while ensuring data safety.

The world is witnessing a boom in the digital age. Digital shops have literally landed into our homes. Almost any required product can now be purchased online via websites or mobile apps without having to step out. Due to online shopping, many customers rely on online reviews from other customers before making a purchase. Customer reviews are gaining more and more importance as they play a probably vital role in the sale and purchase of a product. Customer reviews also provide firsthand feedback coming directly from the customers themselves; this can benefit even the sellers in improving future sales. Analyzing the reviews can provide probable causes for failure or success of a product. Henceforth, the current paper presents the sentiment analysis of the reviews to better understand the feelings expressed by the customers. The very popular and widely used mobile phones were chosen as the product and Amazon was chosen as the digital seller for the current study. Initially, this work began with data preprocessing. Followed by data preprocessing, Bow and n-grams word embedding have been used to represent the clean reviews in vector representation, and then the features were derived. Finally, the performance of supervised machine learning classifiers such as Decision Tree, Naive Bayes, Random Forest, and SVM was empirically evaluated through accuracy, recall, f1-score, and precision. The results of empirical evaluation revealed that the Random Forest Classifier shows best performance with 97.48% accuracy.

Biometrics has reached an important place in the field of authentication for both financial transactions and document verification. Signatures can be broadly classified into online and offline types, depending on how they are acquired. Captured through devices like tablets and digital pens, online signatures contain rich features concerning position, velocity, and acceleration; hence, they offer a better resistance to forgery compared to offline, more traditionally taken signatures. The review summarized the current research in online signature verification systems. There are methodologies and techniques deployed for feature extraction, data pre-processing, and classification. The main stages reviewed within the verification process are about data acquisition, including the use of several publicly available databases like DEEPSIGN, SVC2004 and MCYT-100. Wavelet transforms and Fourier analysis are discussed as a number of methods employed for feature extraction, showing good results about signature dynamics. This review follows the SLR approach for analysing and synthesizing relevant studies published between 2017 and 2024. This review uses PRISMA guidelines for the selection of studies, hence making the results methodologically rigorous and unbiased. The paper identifies commonly used algorithms, including CNN, RNN, and DTW, and examines popular signature databases by outlining their characteristics and relevance to system performance. The insights from this review will help in pointing towards the future ahead in online signature verification systems through emphasizing deep learning-based techniques along with realistic challenges.

Published: December 2024

Bu araştırmanın amacı sinema ve gastronomi bağlamında platform ve menü filmlerinin görsel temsillerinin analiz edilmesidir. Gastronomi, yemek ve yemeğin tekniğine dair birçok detayı içeren ve son yıllarda gelişerek yayılan bir disiplindir. Bu bağlamda gastronomik unsurlar sinemada da kendisine yer almaktadır. Sinema ve yemek ilişkisi sinema tarihiyle birlikte başlamış olsa da çağdaş sinemada yemek geniş bir şekilde yer bulaktadır. Bu bağlamda yemek; sosyal, kültürel, ekonomik ve politik gibi birçok alandan hareketle sinemada yer almaktadır. Yemeğin kendisi, yeme şekilleri ve sunum şekilleri farklı şekillerde metafor olarak kullanılmaktadır. Araştırmanın yöntemini ise nitel araştırma yöntemlerinden olan içerik analizi oluşturmaktadır. İçerik analizi, film, metin ve görsellerin detaylı analizinde kullanılan temel yöntemlerden birisidir. Araştırmanın amacına uygun olduğundan bu yöntem tercih edilmiştir. Araştırmanın çalışma grubunu ise Platform ve Menü filmleri oluşturmaktadır. Analiz için bu filmlerin tercih edilmesinde filmlerin güncel filmler olması ve araştırmanın amacına uygun olması etkili olmuştur. Araştırmadan elde edilen veriler incelendiğinde her iki filmde de yemeğin statü, sınıf ve ekonomik olan sosyal ve kültürel değerlere gönderme yaptığı belirlenmiştir. Platform ve Menü filmlerinin kurgularının distopik bir şekilde gelişmesi yemeğin bu evrendeki yerini çoklu anlamlar üzerinden anlaşılır kılsa da her iki filmde de yemek, toplumsal bir statünün göstergesi ve sınıfsal ayrımın parçasıyla sembolleşmiştir. Bununla birlikte Platform filminde çok daha sembolik bir şekilde yer alan gastronomi ve yemek unsurları Menü filminde çok daha teknik bir şekilde işlenmiştir.

Published: December 2024

The aim of this paper is to delve into semantic-functional aspects of dual-voiced verbs and elucidate their position within the frameworks of two comparative languages to outline their common and distinctive traits. The article reveals unexpected characteristics of dual-voiced verbs in comparative and historic dimensions. It allows qualitative and quantitative analysis of the intensity of verbs with dual functions in the two languages. The topic of the paper covers “ergativity” which becomes the milestone of the research.Ergativity navigates through the systems of the of the two comparative languages. Though originated from the same I-E languages of family, English, and Armenian took different paths in their historical development of ergative verbs that is dictated by the changes in language aspects and these shifts yielded to the changes on the one hand, in their functional occurrence and on the other hand, in a various spectrum of semantic nuances. This divergence emphasizes how languages adapt to shifting communication needs through a variety of ways and how dynamic language evolution is. The research contributes to a wider knowledge of linguistic change across languages by analyzing these trends and providing insights into how language evolution has changed the syntax and usage of ergative verbs in English and Armenian.

Published: December 2024

This paper examines the dichotomy between humanism and the ideological construction of Englishness in the light of post-colonialism. The study mainly relies on imperialism as the hegemonic “center,” which inherently affects the “margin.” That is, the dominant Western imperial hegemony imposes its culture and identity upon the colonized nations. Therefore, it will unravel Western domination as the “center” and the colonized nations as the “margin.” In this sense, it will highlight this dichotomy by applying Edward Said’s concept of the self-other relationship, whereby the Western hegemony will be identified as the dominant “self,” which leaves its apparent social and cultural impact upon the identity of the colonized “other” nations. As such, the study’s methodology follows a textual analysis of some literary works that depict the dichotomy between humanism and the ideological construction of Englishness. It will demonstrate how the imperial “self” drastically projects its cultural influence upon the colonized “other,” which is the recipient of Englishness per se.
The Impact of the Rereading Method on Reading Speed and Comprehension of Normal and Scrambled Texts among Arabic EFL Learners
Authors: Almaiman Ibrahim
Published: December 2024

The rereading method benefits automatic word recognition, which impacts the development of L2 learners' reading speed and text comprehension. This study aimed to compare the effect of the rereading method on reading speed and reading comprehension of normal and scrambled texts in Arabic EFL learners. It was developed through quantitative research of analytical design to analyze the behavior of reading speed and text comprehension. The study focused on 50 Arab first-year EFL learners, divided into two groups, low and high level, according to their reading ability. They were given to read scrambled (S) and normal (N) passages with the conditions NN, SS, SN, and NS. The results show that when students are confronted with reading of the second passage preceded by normal texts, they read faster, presenting the same behavior for the general sample as for the low- and high-level groups. On the other hand, the rereading method favors reading speed when the second passage is scrambled. High-level students were shown to read faster, regardless of the condition of the passage. Regarding text comprehension, when the second passages are scrambled (SS, NS), students present better text comprehension. These results suggest that despite the difficulty of the text, a transfer from the first passage to the second readings may occur. The results indicate that the rereading method improves text comprehension and reading speed.

Authors: Alfahid Mai Fahid , Yousuf Zai Sajid Ali
Published: December 2024

The Self-Regulated Learning (SRL) Strategies have served as a basis in blended classrooms over a period of time to conduct experiments on various students’ problems. The technique of blended classrooms has shown optimistic results and has offered new opportunities for improving students' reading and learning skills, mainly known as receptive language proficiency. This study investigated how integrating SRL strategies within a blended classroom enhances English as a Foreign Language (EFL) learners' reading comprehension and writing skills. A quasi-experimental research design was employed, with participants divided into an experimental group, which utilized SRL strategies, and a control group, which did not. The findings revealed that the experimental group significantly outperformed the control group in both writing and reading comprehension skills. The mean scores for the experimental group were 84.30 for writing skills and 87.20 for reading comprehension, compared to 66.70 and 70.10, respectively, in the control group. These statistically significant differences, with p-values less than 0.001, confirm that SRL strategies substantially enhance students' receptive language proficiency in a blended EFL classroom. Furthermore, SRL strategies effectively improved reading comprehension at all levels—literal, inferential, and critical—highlighting their comprehensive impact on students' cognitive development. This study highlights the importance of incorporating SRL strategies in blended learning environments to improve EFL learners' language proficiency, offering a valuable approach for educators aiming to enhance students' reading and writing capabilities.

The Politics of Allowances in Waziristan During the British Raj
Authors: Saeeda
Published: December 2024

The paper describes the nineteenth and early twentieth century British Indian Government dealings with the Wazir tribe dwelling on the North-West Frontier of the subcontinent. In view of the steady advances of Russians in Central Asia, the British Indian Government thought it necessary to control the Wazir tribe because it was essential to the security of India in the North-West Frontier. Therefore, the British evolved such an administrative system by virtue of which they could exercise influence over them. One of the main elements of arrangement was the payment of allowances and subsidies to the Wazir tribe. The paper argues that the payment of allowances to Wazir tribe created a considerable strategic space and time for the then British Empire to pursue its colonial interests and initiate the Great Game, in a recurrent competition with the 19th century expanding Czarist Empire. The paper follows a historical approach relying mainly on archival sources and an inductive interpretation of these archival sources involves, methodologically, an empiric-analytic reasoning that adds to research on the subject.

The goal of this study is to turn waste into value by producing lubricant from abandoned avocado fruits, as the globe looks for more environmentally friendly and sustainable lubricants than those derived from fossil fuels. In response to the growing need for high-performance, environmentally friendly products, we created a lubricant enriched with copper oxide nanoparticles (nCuO) using avocado oil as the foundation. The nano copper oxide was elucidated using XRD. To find out how these nanoparticles impact the oil’s viscosity, thermal stability, and other important characteristics, we introduced trace amounts of nCuO at concentrations of 0.4 wt%, 0.8 wt%, and 1.2 wt% in our studies. The nanofluids underwent 3.5 hours of ultrasonication at 75°C. The formulation with 0.8 weight percent nCuO proved to be the most effective, with a higher flash point of 220°C and viscosities of 7.5 cSt at 40°C and 2.7 cSt at 100°C, all of which satisfied the ASTM D445 standards. Furthermore, as compared to pure avocado oil, the ideal formulation demonstrated a 13.6% decrease in the coefficient of friction (COF) and a 16.9% decrease in wear rate. Good low-temperature performance was indicated by the pour point of -1°C and the cloud point of 15°C, respectively. According to the thermal conductivity measurements, the oil’s capacity for heat transport was improved by the addition of nCuO. These results imply that avocado oil-based nanofluids, especially those containing 0.8 weight percent nCuO, have great potential as high-performing, environmentally friendly substitutes for lubricating light-duty engines and other industrial uses.
Asociativismo intermunicipal en Paraguay: evolución normativa, iniciativas inconclusas y reflexiones para su consolidación
Authors: Paredes Olga
Published: December 2024

El presente artículo aborda el desarrollo y las limitaciones del asociativismo intermunicipal en Paraguay desde un enfoque teórico y exploratorio. A partir de una revisión de la evolución normativa y las principales iniciativas asociativas surgidas en el país, se expone la falta de consolidación de estos esfuerzos como uno de los desafíos centrales para el fortalecimiento de la descentralización y la gobernanza local. A pesar de la consagración del derecho al asociativismo intermunicipal en la Constitución de 1992, el país no cuenta con una ley específica que regule su implementación, lo que genera un vacío legal que dificulta la coordinación y sostenibilidad de estos procesos. El análisis revela la proliferación de iniciativas inconclusas, marcadas por la falta de recursos, apoyo institucional y claridad en sus objetivos. Además, se cuestiona el papel de la Organización Paraguaya de Cooperación Intermunicipal (OPACI) por su falta de transparencia y su ineficacia como promotora del asociativismo, sugiriendo la necesidad de una auditoría independiente. Se destaca, asimismo, la necesidad de reformar el marco legal para las áreas metropolitanas y el papel de los gobiernos departamentales en la promoción del asociativismo intermunicipal. En conclusión, el artículo sugiere que para aprovechar plenamente el potencial del asociativismo como herramienta de desarrollo local, es esencial contar con una normativa específica y fortalecer las capacidades de las entidades involucradas.
Factores que intervienen en el arraigo campesino: caso de la compañía Boquerón, distrito de Mbuyapey, periodo 2008-2018
Authors: Florentín Rodolfo Eduardo
Published: December 2024

Este artículo presenta los resultados de una investigación cualitativa y descriptiva que describe los factores que promueven el arraigo en la comunidad rural de Boquerón, en Mbuyapey, Paraguay, durante el periodo 2008-2018. Se estudiaron aspectos económicos, institucionales y socioculturales que contribuyen a la permanencia de los pobladores en su comunidad. Los resultados muestran que el acceso a la tierra y la diversidad de actividades campesinas fomentan tanto la producción de alimentos para autoconsumo como la generación de ingresos, lo que propicia la permanencia en la comunidad. En el ámbito institucional, se destaca el impacto positivo de las transferencias monetarias para adultos mayores y del programa Tekoporã, los cuales mejoran la economía local y refuerzan el arraigo. Finalmente, los factores socioculturales, como la vida de campo, el reconocimiento vecinal y los lazos familiares, fortalecen la solidaridad y el sentido de pertenencia, contribuyendo así a que los habitantes se sientan ligados a su compañía.
Tareas de cuidado de madres cuidadoras de niños con discapacidad severa atendidos en un centro de rehabilitación, año 2022
Authors: Coppens Sosa María de la Paz , Araujo Méndez Yessica Nohely , Ruffinelli Rosa
Published: December 2024

Este estudio describe las implicancias de las tareas de cuidado asumidas por madres de niños con discapacidad severa atendidos en un centro de rehabilitación público. Con un enfoque cualitativo y diseño observacional, se realizaron entrevistas en la sala de espera del centro para comprender sus percepciones. Los resultados muestran que, al carecer de apoyo, estas madres enfrentan barreras significativas para participar en actividades fuera del hogar, lo que genera dependencia económica de familiares o parejas. Además, la dedicación exclusiva al cuidado las obliga a abandonar estudios o trabajos, limitando su desarrollo personal y profesional. Se evidencia la necesidad de implementar políticas públicas sostenibles que incluyan servicios especializados de apoyo, como guarderías con fisioterapeutas, psicopedagogos y trabajadores sociales, para permitir a estas madres retomar sus actividades y alcanzar un mayor bienestar socioeconómico. El estudio destaca la urgencia de abordar la problemática del cuidado desde un enfoque integral que contemple el acceso equitativo a recursos y oportunidades.

Aim: To assess chlorhexidine (CHG) susceptibility among resident microbiota from hands of healthcare workers (HCWs) after a period of continuous CHG soap use for handwashing compared to plain soap.
Methods: Before-after crossover study in a not-for-profit private tertiary care hospital in São Paulo, Brazil from April 2016 to April 2018. We alternated control (plain soap) and intervention periods (CHG soap) in selected wards at intervals of four to eight months. We collected the HCWs hand sample before each period swap along with the application of a questionnaire about product tolerability. MALDI-TOF was used for species identification, and CHG susceptibility testing was performed with agar dilution.
Results: We obtained 259 samples yielding 422 isolates and 24 different genera. We observed increased MIC values for Staphylococcus epidermidis in the intervention (MIC50 4 mg/L and MIC90 16 mg/L) compared to baseline and control groups (MIC50 2 mg/L and MIC90 4 mg/L). We detected a higher proportion of gram-negative bacteria and Candida spp. in the intervention than in the baseline group (23% vs 49%; RR 1.91 [CI95% 1.27-2.89]; P=0.001). Skin dryness was more frequent in the intervention group, and better skin comfort was reported within control group.
Conclusion: The MIC values for the most prevalent gram-positive bacteria in HCWs’ hands tended to increase after continuous CHG use. CHG´s handwashing practice seems to modify the microbiological profile and increase skin intolerance among HCWs.

Authors: Demir Ekin , a Fatih , evik Kadir , Ba Can , Ayhan Egemen
Published: December 2024

Objectives:
Our aim was to evaluate outcomes of surgical treatment methods (open reduction and internal fixation (ORIF), hemi-hamate arthroplasty (HHA), volar plate arthroplasty (VPA), dynamic external fixation and extension block percutaneous pinning in proximal interphalangeal (PIP) joint injuries.
Methods:
This retrospective study was conducted on 34 patients who were surgically treated for PIP joint dislocation or fracture dislocation between 2016 and 2022. Patients were grouped according to treatment method. Visual analogue scores (VAS), Quick disabilities of the arm,shoulder and hand (DASH) scores, range of motion (ROM), grip strengths and subluxation on radiographs were analyzed.
Results:
Mean age was 35.7±15.9 years. 8 patients underwent extension block percutaneous pinning, 7 patients each underwent dynamic external fixation and ORIF, and 6 patients each underwent VPA and HHA. Median Quick DASH score was 4.5 [0-10.7], median VAS was 1 [0-2], median ROM was 75° [56.3°-90°] mean grip strength difference was 4.4±7.6 kg. There were no differences between groups in Quick DASH (p=0.309), VAS (p=0.219), ROM (p=0.719), loss of grip strength (p=0.938). Subluxation was seen in 7 patients. There was no statistically significant difference between clinical results of patients with and without subluxation (p=0.892 for Quick DASH, p=0.158 for VAS, p=0.164 for ROM).
Conclusion:
Choosing appropriate surgical treatment after PIP joint injury improves clinical and functional outcomes. It should be kept in mind that application of dynamic external fixation is challenging in terms of patient comfort and re-subluxation may occur in patients who underwent VPA.
