Authors: Vianita Etna
Published: March 2024

The improvement of plantation forecasting accuracy, particularly with regard to coffee production, was an essential aspect of earth observations for the purpose of informing plantation management alternatives. These decisions included strategic and tactical decisions on supply chain operations and financial decisions. Many research initiatives have used a variety of methodologies to the forecasting of plantation areas and related industries, such as coffee production. One of these methods was known as the fuzzy time series (FTS) technique. This  study combined ratio-interval and frequency density to get universe of discourse and partition followed by adopted weighted and modified that weighted. The first step was defined universe of discourse using ratio-interval algorithm. The second step was partition the universe of discourse using ratio-interval algorithm followed by frequency density partitioning. The third step was fuzzyfication. The fourth step built fuzzy logic relationship (FLR) and fuzzy logic relationship group (FLRG). The fifth step was adopted the modification weighted. The last step was defuzzyfication. The  models evaluated  by  average  forecasting  error  rate  (AFER)  and  compared  with  existing methods.  AFER  value  1.24%  for  proposed method.

Published: March 2024

The purpose of this study was to describe the presence or absence of the influence of the infusion learning model collaboration with Problem-Based Learning (PBL)  to develop students' understanding of proof and mathematical argumentation in number theory courses. This research is an experimental study with a randomized control group pretest-posttest design, two groups namely the experimental group and the control group. The experimental group is the group that uses the infusion learning model in collaboration with PBL, while the control group is the group that uses conventional learning. The subjects of this study consisted of 40 students at a university in Jombang, Indonesia. Data collection techniques through observation sheets, proof understanding tests and observation sheets of students' mathematical argumentation abilities. The results of the research show that the significant difference between the average proof of understanding of students in the experimental group and the control group. The difference between the average proof of understanding in the experimental group and the average proof of understanding of students in the control group was 21.75. Furthermore, the significant difference between the average argumentation ability of students in the experimental group and the control group. The difference between the average argumentation ability of students in the experimental group and the average argumentation ability of students in the control group is 5.25. Therefore, the implementasion of infusion learning in collaboration with PBL is more effective than conventional learning models for developing students' ability to understand mathematical proof and argumentation. This learning model promotes the development of critical thinking skills, problem-solving, conceptual and different understanding needed to construct a formal proof, and strong and valid arguments.

Published: March 2024

Abstract - The purpose of this study is to find the relationship between audit quality and good corporate governance (GCG) on dividend policy. Where the supervision provided by the company's independent auditors and independent board of commissioners has an impact on the returns received by investors in the form of dividends. The study was conducted using purposive sampling technique, taking 141 samples of non-financial public companies in Indonesia from the period of 2017-2019. The data were processed using the STATA program. The results of this study show evidence that the audit quality variable with the proxy of the Big 4 public accounting firm has a positive and significant effect on dividend policy. Which may be resulted from a better quality of supervision thus reducing agency conflicts. However, for the GCG variable, there is no evidence of an influence on dividend policy which may be resulted from different proxy variables.

Abstract— This study aims to analyze the capital adequacy ratio, non-performing loans, operating income operating expenses, loan to deposit ratio, firm size, net interest margin, DPK, inflation, and the exchange rate on bank profitability. This type of research is associative research. The data used for this research is data sourced from the financial statements of commercial banks that are listed consecutively on the Indonesia Stock Exchange (IDX) period 2016-2020. The type of data taken is banking financial statements. The data was obtained from the official website of the Indonesia Stock Exchange (IDX). The data obtained from the research results were analyzed using a regression analysis model with the help of the Eviews 10 program. The results showed that only the CAR, NPL, and NIM variables had a significant influence on the return on assets of commercial banks listed on the Indonesia Stock Exchange period 2016 – 2020. This is in accordance with the provisions because sufficient capital, a decrease in the number of non-performing loans, and a high level of bank effectiveness in managing company assets will be able to increase profitability. Then the BOPO, LDR, firm size, DPK, inflation, and exchange rate variables cannot have a significant effect on the return on assets of commercial banks listed on the Indonesia Stock Exchange period 2016 – 2020.

A Rhetorical Stylistic Analysis of English Political Headlines in Selected Newspapers
Authors: Hassan Sawsan
Published: March 2024

This study explores the language used in reporting political headlines conducting a rhetorical stylistic analysis. It is based on showing the effect of the rhetorical stylistic relations in news reporting. The aim is to investigate the structure adopted in reporting political news. It argues that the rhetorical stylistic devices are necessary and applicable to non-literary texts, i.e. political headlines to evaluate language use in the representation of non-literary texts. The analysis was carried out on data selected from the British broadsheet The Guardian and the American New York Times newspaper headlines. The data were examined and subjected to a contrastive analysis incorporating rhetorical and stylistic tools to discern how they are united to achieve the main purpose of language use, i.e. to persuade and grasp the reader's attention. It was found that the two newspapers tend to employ sentence structures differently in terms of nucleus and satellite relations demonstrating the significant part in a sentence. Examples of the deviation strategy of foregrounding were primarily established in the New York Times to maintain the reader's attention about the content underlying the different strategy of the two newspapers to report war circumstances. The analysis shows that rhetorical devices and stylistic features are found and closely related in newspaper articles.

Authors: Lim Geok Hoon , Allen John Carson , Lee Yien Sien , Teo Sze Yiun , Lau Li Ching , Win Thida , Leong Lester Chee Hao
Published: March 2024

INTRODUCTION: Chemotherapy is conventionally offered to non-stage IV breast cancer patients with metastatic nodes. However, the RxPONDER trial showed that chemotherapy can be omitted in selected patients with 1–3 metastatic nodes if the 21-gene assay recurrence score is ≤25. We aimed to investigate if axillary ultrasound can identify this group of patients with limited nodal burden so that they can undergo upfront surgery followed by gene assay testing, to potentially avoid chemotherapy. METHODS: T1-3, node positive, hormone receptor-positive and HER2-negative breast cancer patients ≥50 years old with axillary lymph node dissection (ALND) were reviewed from 2 centres. Patients with neoadjuvant chemotherapy and bilateral cancers were excluded. Number of ultrasound-detected abnormal axillary nodes, demographic and histological parameters were correlated with the number of metastatic nodes found on ALND. RESULTS: 138 patients were included, 59 (42.8%) and 79 (57.2%) patients had 1–3 and >3 metastatic nodes on ALND respectively. On logistic regression and ROC analysis, the number of ultrasound-detected abnormal nodes was significant (p < 0.001) for predicting limited nodal burden (ROC AUC = 0.7135). Probabilities of <4 metastatic nodes with ultrasound cut-offs of 5, 6 and 8 abnormal nodes were 0.057, 0.026 and 0.005 respectively, with 100% specificity. CONCLUSION: A cut-off of ≤5 ultrasound-detected abnormal nodes can distinguish between patients with limited versus high nodal burden, with high specificity. Hence, incorporating the number of abnormal ultrasound-detected nodes into clinical practice may prove useful in guiding between upfront surgery and gene assay testing or neoadjuvant chemotherapy in this group of patients.

Published: March 2024

Background:

A theoretical endpoint staging framework was previously developed and published, aligning outcomes (i.e., memory) to the stage of Alzheimer’s disease (AD) in which a given outcome is most relevant (i.e., has the greatest risk of degradation). The framework guides the selection of endpoints measuring outcomes relevant within a target AD population. Here, a proof of concept is presented via post-hoc analyses of the Alzheimer Management by Albumin Replacement (AMBAR) Phase 2b clinical trial in patients with AD (NCT01561053, 2012).

Objective:

To evaluate whether aligning endpoints measuring cognition, function, and quality of life to hypothesized ‘target’ stages of AD yields magnitudes of treatment efficacy greater than those reported in the AMBAR full analysis set (FAS).

Methods:

Three endpoints were tested: ADAS-Cog 12, ADCS-ADL, and QoL-AD. The magnitude of treatment efficacy was hypothesized to be maximized in the target stages of mild, mild-to-moderate, and very mild AD, respectively, compared to the full analysis set (FAS) and non-target stages.

Results:

For ADAS-Cog 12, the magnitude of treatment efficacy was largest in the non-target stage (–4.0, p = 0.0760) compared to target stage and FAS. For ADCS-ADL and QoL-AD, the magnitude of treatment efficacy was largest in the target stage (14.2, p = 0.0003; 2.4, p < 0.0001, respectively) compared to non-target stage and FAS.

Conclusions:

Findings indicated that evaluating endpoints in the most relevant AD stage can increase the magnitude of the observed treatment efficacy. Evidence provides preliminary proof of concept for the endpoint staging framework.
Freesurfer Software Update Significantly Impacts Striatal Volumes in the Huntington’s Disease Young Adult Study and Will Influence HD-ISS Staging
Authors: Knights Harry ,   the HD-YAS investigators, Coleman Annabelle , Hobbs Nicola Z. , Tabrizi Sarah J. , Scahill Rachael I.
Published: March 2024

Background: The Huntington’s Disease Integrated Staging System (HD-ISS) defined disease onset using volumetric cut-offs for caudate and putamen derived from FreeSurfer 6 (FS6). The impact of the latest software update (FS7) on volumes remains unknown. The Huntington’s Disease Young Adult Study (HD-YAS) is appropriately positioned to explore differences in FS bias when detecting early atrophy. Objective: Explore the relationships and differences between raw caudate and putamen volumes, calculated total intracranial volumes (cTICV), and adjusted caudate and putamen volumes, derived from FS6 and FS7, in HD-YAS. Methods: Images from 123 participants were segmented and quality controlled. Relationships and differences between volumes were explored using intraclass correlation (ICC) and Bland-Altman analysis. Results: Across the whole cohort, ICC for raw caudate and putamen was 0.99, cTICV 0.93, adjusted caudate 0.87, and adjusted putamen 0.86 (all p < 0.0005). Compared to FS6, FS7 calculated: i) larger raw caudate (+0.8%, p < 0.00005) and putamen (+1.9%, p < 0.00005), with greater difference for larger volumes; and ii) smaller cTICV (–5.1%, p < 0.00005), with greater difference for smaller volumes. The systematic and proportional difference in cTICV was greater than raw volumes. When raw volumes were adjusted for cTICV, these effects compounded (adjusted caudate +7.0%, p < 0.00005; adjusted putamen +8.2%, p < 0.00005), with greater difference for larger volumes. Conclusions: As new software is released, it is critical that biases are explored since differences have the potential to significantly alter the findings of HD trials. Until conversion factors are defined, the HD-ISS must be applied using FS6. This should be incorporated into the HD-ISS online calculator.
Detection of an in-housed pig using modified YOLOv5 model
Authors: Devi Salam Jayachitra , Doley Juwar , Gupta Vivek Kumar
Published: March 2024

Object detection has made significant strides in recent years, but it remains a challenging task to accurately and quickly identify and detect objects. While humans can easily recognize objects in images or videos regardless of their appearance, computers face difficulties in this task. Object detection plays a crucial role in computer vision and finds applications in various domains such as healthcare, security, agriculture, home automation and more. To address the challenges of object detection, several techniques have been developed including RCNN, Faster RCNN, YOLO and Single Shot Detector (SSD). In this paper, we propose a modified YOLOv5s architecture that aims to improve detection performance. Our modified architecture incorporates the C3Ghost module along with the SPP and SPPF modules in the YOLOv5s backbone network. We also utilize the Adam and Stochastic Gradient Descent (SGD) optimizers. The paper also provides an overview of three major versions of the YOLO object detection model: YOLOv3, YOLOv4 and YOLOv5. We discussed their respective performance analyses. For our evaluation, we collected a database of pig images from the ICAR-National Research Centre on Pig farm. We assessed the performance using four metrics such as Precision (P), Recall (R), F1-score and mAP @ 0.50. The computational results demonstrate that our method YOLOv5s architecture achieves a 0.0414 higher mAP while utilizing less memory space compared to the original YOLOv5s architecture. This research contributes to the advancement of object detection techniques and showcases the potential of our modified YOLOv5s architecture for improved performance in real world applications.

Published: March 2024

Assessing the effectiveness of physical education instruction, students’ learning, and the feedback received from the teaching process are all vital components of the physical education teaching process in colleges and universities. Improving the quality of physical education instruction in these settings is essential. With its ability to drive the digital revolution of physical education in schools, intelligent technology is bringing about significant changes in the field of education and drawing attention from people from all walks of life. To assess intelligent technology’s impact on physical education instruction in a scientific manner, this study utilizes the latest intelligent analysis and sensing data mining to design an intelligent physical education measurement and evaluation model, which utilizes GPS positioning, built-in maps, and gravity sensing to provide real-time feedback on the trajectory, distance, and time of the movement, and then calculates the real-time and average speed of the movement, as different students’ body postures to achieve the the same effect when the required speed is not the same, this paper randomly selected students with different BMI index for empirical analysis. The experimental results show that the principal components of the factor analysis extracted four common factors with a cumulative contribution rate of 69.5%, and the test-retest reliability of the four dimensions is 0.665–0.862.

When one logic is not enough: Integrating first-order annotations in OWL ontologies
Authors: Flügel Simon , Glauer Martin , Neuhaus Fabian , Hastings Janna
Published: March 2024

In ontology development, there is a gap between domain ontologies which mostly use the Web Ontology Language, OWL, and foundational ontologies written in first-order logic, FOL. To bridge this gap, we present Gavel, a tool that supports the development of heterogeneous ‘FOWL’ ontologies that extend OWL with FOL annotations, and is able to reason over the combined set of axioms. Since FOL annotations are stored in OWL annotations, FOWL ontologies remain compatible with the existing OWL infrastructure. We show that for the OWL domain ontology OBI, the stronger integration with its FOL top-level ontology BFO via our approach enables us to detect several inconsistencies. Furthermore, existing OWL ontologies can benefit from FOL annotations. We illustrate this with FOWL ontologies containing mereotopological axioms that enable additional, useful inferences. Finally, we show that even for large domain ontologies such as ChEBI, automatic reasoning with FOL annotations can be used to detect previously unnoticed errors in the classification.
A behaviouristic semantic approach to blockchain-based e-commerce
Authors: Bella Giampaolo , Cantone Domenico , Castiglione Gianpietro , Nicolosi Asmundo Marianna , Santamaria Daniele Francesco
Published: March 2024

Electronic commerce and finance are progressively supporting and including decentralized, shared and public ledgers such as the blockchain. This is reshaping traditional commercial activities by advancing them towards Decentralized Finance (DeFi) and Commerce 3.0, thereby supporting the latter’s potential to outpace the hurdles of central authority controllers and lawgivers. The quantity and entropy of the information that must be sought and managed to become active participants in such a relentlessly evolving scenario are increasing at a steady pace. For example, that information comprises asset or service description, general rules of the game, and specific technologies involved for decentralization. Moreover, the relevant information ought to be shared among innumerable and heterogeneous stakeholders, such as producers, buyers, digital identity providers, valuation services, and shipment services, to just name a few. A clear semantic representation of such a complex and multifaceted blockchain-based e-Commerce ecosystem would contribute dramatically to make it more usable, namely more automatically accessible to virtually anyone wanting to play the role of a stakeholder, thereby reducing programmers’ effort. However, we feel that reaching that goal still requires substantial effort in the tailoring of Semantic Web technologies, hence this article sets out on such a route and advances a stack of OWL 2 ontologies for the semantic description of decentralized e-commerce. The stack includes a number of relevant features, ranging from the applicable stakeholders through the supply chain of the offerings for an asset, up to the Ethereum blockchain, its tokens and smart contracts. Ontologies are defined by taking a behaviouristic approach to represent the various participants as agents in terms of their actions, inspired by the Theory of Agents and the related mentalistic notions. The stack is validated through appropriate metrics and SPARQL queries implementing suitable competency questions, then demonstrated through the representation of a real world use case, namely, the iExec marketplace.
Emotional burnout, job satisfaction, and intention to leave among pre-hospital emergency healthcare workers during the COVID-19 pandemic
Authors: Aras Fatih Mehmet , Gümüşsoy Süreyya
Published: March 2024

BACKGROUND: With the onset of the COVID-19 pandemic, pre-hospital emergency healthcare workers (PHEHW) assumed critical responsibilities in controlling and preventing the spread of the virus. OBJECTIVE: This descriptive study aimed to explore the emotional burnout, job satisfaction, and intention to leave among PHEHW during the COVID-19 pandemic. METHODS: The study was conducted with 401 emergency medical technicians and paramedics. The Sociodemographic Data Form, the Emotional Burnout Scale, the Job Satisfaction Scale, the Intention to Leave the Profession Scale were used to collect data. The findings were assessed with a significance level set at p < 0.05 and a 95% confidence interval. RESULTS: The participants demonstrated moderate scores in emotional burnout, job satisfaction, and intention to leave the profession. The analysis revealed a negative correlation, indicating that as emotional burnout increased, job satisfaction decreased, and the intention to leave the profession heightened. Notably, the participants who had 6–9 years of service, lacked knowledge about COVID-19, had no COVID-19 training, underwent COVID-19 testing, and experienced the loss of a healthcare worker due to COVID-19 exhibited higher levels of burnout. Furthermore, those who had 6–9 years of service, lacked knowledge about COVID-19, had no COVID-19 training, and lost a healthcare worker due to COVID-19 reported lower levels of job satisfaction. Additionally, participants who had 6-9 years of service, lacked knowledge about COVID-19, had no COVID-19 training, and experienced the loss of a healthcare worker due to COVID-19 displayed a greater intention to leave the profession. CONCLUSIONS: It is important to implement improvement initiatives that will increase the motivation and job satisfaction of PHEHW.

The importance of studying the pathogenesis of computer vision syndrome (CVS) is due to the ever-increasing number of users of digital information technologies (DITs) and visual dis-play devices (VDDs) who work with them for long periods of the day. Most studies have classi- cally focused on epidemiological and etiological aspects of CVS. This article analyses 9 national and 42 international studies on CVS with a focus on its pathogenesis. The pathophysiological aspects of dry eye syndrome and accommodative dysfunction as the main branches of CVS in DIT and VDD users are discussed in the light of the morphological and functional unity of visual functions. The role of psychological status in the development and progression of refractive errors due to abnormalities in serotonin and dopamine metabolism is emphasized. Classical and recently published data on the possible role of sensory and visual-motor integration of the two main visual analyzer information channels (dorsal and ventral) in the development of CVS are discussed. A hypothesis based on the literature data and the results of our own research on the disintegration of visual and visual-motor processes in the development of CVS as a result of excessive, uncontrolled use of VDDs is hypothesized based on published data and the author's results.

Published: March 2024

The twenty-first century offers excellent opportunities for engineering institutions to grow. These opportunities demand an appropriate culture to facilitate the institute faculty members and develop them to offer cutting-edge programs. Many institutes suffer from a want of an appropriate winning culture. The objectives of this research are to assess the harms created by toxic leaders in distorting the academic culture, to explore methods to eradicate toxic leaders' actions, to suggest needed winning cultures to facilitate institutional growth, and to identify strategies to institutionalize the winning culture. 1253 faculty members were purposely selected for this research. The twenty-first century offers more opportunities for engineering colleges to develop interdisciplinary programs, offer consultancy projects, undertake sponsored research projects, and provide excellent jobs for graduates. Methods to eradicate the actions and distorted cultures created by toxic leaders were explored. Based on the literature survey, existing cultural models of corporates were identified. Significant cultural models of world-class universities were identified. The harm created by toxic leaders was identified. Appropriate methods to eradicate the actions and distorted cultures created by toxic leaders were synthesized. A needed culture for creating and maintaining high-performance research teams was recommended. A model for a desired set of academic cultures was developed. The model was validated through three engineering institutions and found to be satisfactory. Shortcomings of this research have been identified. Suggestions for further research on engineering culture have been indicated.

Many diseases, such as hypertension, obesity, diabetes, arthritis, and cancer, are caused by inflammation resulting from oxidative stress and dysbiosis. Oxidative stress is triggered by reactive oxygen species (ROS), and long-term inflammation contributes to aging. Inflammation damages DNA, carbohydrates, proteins, and lipids at the cellular and tissue levels. Cytokines such as IL-1β, IL-6, tumor necrosis factor-alpha (TNF-α), and COX-2 are produced through nuclear factor-kappa B (NF-κB) mediation, and ROS is associated with NF-κB activation. Angiogenesis is initiated by the release of angiogenic growth factors and cytokines, including vascular endothelial growth factor (VEGF), transforming growth factor-β (TGF-β), TNF-α, prostaglandin E2 (PGE2), nitric oxide (NO), IL-1, IL-6, and IL-8 from macrophages, affecting endothelial cells. Fibroblasts are activated by TGF-β, which is secreted by macrophages and leads to fibrosis. Prolonged oxidative stress caused by ROS is a major contributor to aging. To delay the aging process, it is important to reduce oxidative stress and NF-κB activation. Celecoxib and symbiosis have the potential to prevent aging by regulating NF-κB activation. Additionally, maintaining a healthy lifestyle with regular exercise and a balanced diet can help reduce oxidative stress and delay aging. It is important to consider a range of anti-aging strategies, including both pharmaceutical interventions and lifestyle changes.

El rechazo escolar es una actitud negativa reiterada hacia la asistencia y/o permanencia en el centro durante todo el día escolar. Entre sus graves consecuencias destaca el desarrollo de psicopatologías, las cuales podrían reducirse teniendo una adecuada regulación emocional y siendo asertivo. Acerca de la asertividad, aunque se considera una de las dificultades interpersonales más recurrentes en la adolescencia, no existen evidencias empíricas sobre cómo afecta al rechazo escolar. Por ello, el objetivo principal de este estudio se centró analizar las diferencias entre los perfiles de rechazo escolar y la asertividad en una muestra de 847 adolescentes españoles de entre 15 y 18 años. Para ello, se emplearon la School Refusal Assessment Scale-Revised y el Cuestionario de Evaluación de Dificultades Interpersonales en la Adolescencia. Se compararon las puntuaciones medias entre los perfiles con altas y bajas puntuaciones para cada factor de la SRAS-R en base a la dificultad para ser asertivo. Entre los adolescentes que puntuaban alto y bajo en los dos primeros factores, hubo diferencias estadísticamente significativas respecto a la asertividad con magnitudes moderadas y pequeñas, respectivamente. Se discuten las posibles explicaciones e implicaciones para la Psicología de la Educación.

In the era of modernization, the movement of the multitude from rural to urban regions all over the globe is rising swiftly. This movement crafts so many socio-economic prospects for the masses. However, in chorus, it has made severe challenges for the eminence of the environment due to a decrease in forestation and the arrangement of more buildings and plants, causing CO2 emissions.  It is unmanageable to edge the endurance of urbanization, and the issue is how we can switch its adversative effects on the environment. This study investigated the moderating role of renewable energy consumption in the urbanization-CO2 nexus. For this study, twenty-three of the most urbanized economies from around the world were chosen from 1997 to 2021. Three econometrics techniques are applied for empirical investigation: fixed effect model, robust least square and panel quantile regression with twelve model specifications. The dependent variable is carbon dioxide (CO2) emissions. The explanatory variables are gross fixed capital formation, patent application, inflation, financial development, industrial growth, urbanization and interaction term of renewable energy and urbanization. To check the robustness of empirical findings, we used four different proxies of (CO2) emissions and three different proxies of urbanization.  In our empirical findings, patent application, inflation and industrial growth are positively and significantly associated with all proxies of CO2 emissions. While financial development is inversely and significantly allied with CO2 emissions. The impact of all proxies of urbanization is positive and significant on CO2 production. But the moderating effect of renewable energy on environmental depredation is inverse and significant. It suggests using clean and renewable energy and developing the financial sector to improve the eminence of the environment. Our research aligns with the sustainable development goals and the corporate social responsibility stream, making some valuable contributions to the body of previously established research.
