Authors: Iadkert Kamonnate , Hassan Roshidah , Hashim Azirah
Published: June 2024

Effective English communication across different languages and cultures has become increasingly important in a globalised world. To gain a deeper understanding of the segmental features of Thai speakers of English, this study aims to investigate the production of English monophthongs and diphthongs by Thai speakers and examine how intelligible their pronunciations are to others. Data were collected through two tasks: a production task and a listening task. For the production task, three Thai female speakers were chosen as the participants. They were recorded reading a passage consisting of all targeted vowels, and a total of 180 English tokens were analysed. For the listening task, thirty Malaysian listeners were asked to evaluate the speech intelligibility of the English sounds produced by the three speakers. The duration and formant frequencies of English vowels produced were measured to investigate the characteristics of the monophthongs and diphthongs. The findings show that there were significant differences in the durations between long and short vowels of the monophthongs, but there were no significant differences in the vowel quality produced. The ROC (rate of change) of formant frequencies (F1 and F2) indicates that there was no formant movement for the diphthongs /eɪ/, /əʊ/, and /eə/. The three diphthongs showed similar characteristics as other ASEAN Englishes that are monophthongal as /e:/, /o:/, and /ɛ:/, respectively. These findings confirm that speakers’ L1 influences English vowel production. Although there were vowel variations in the characteristics of the vowels produced by the speakers, the intelligibility scores were high.

Authors: Ariani Farida , Kustati Martin , Reflianto Reflianto , Yanti Novi , Wandi Joni Indra
Published: June 2024

Incorporating digital-based learning is crucial for fostering self-directed learning among students. Various digital media platforms, such as Google Classroom, Zoom Meetings, and social media, motivate students to actively engage in their studies. This study aims to assess the effectiveness of the Flipped Digital Classroom (FDC) method on student engagement and English writing proficiency. It employs a quasi-experimental 2x3 factorial pretest-post-test non-equivalent group design and collected data through the Student Engagement in Schools Questionnaire and an English writing test. The FDC group receives pre-recorded lectures, additional reading materials, and online writing assignments before face-to-face discussions, while the control group follows a lecture-based approach with assignments. The analysis involves 48 FDC students and 51 controls, categorized by engagement levels (high, medium, low). Validity and reliability tests are conducted on the questionnaire data, rated on a 5-point Likert scale, while English proficiency is assessed using an English Writing Test. Hypothesis testing utilizes descriptive and inferential statistics, including Two-Way ANOVA. The results indicate a significant 18-point increase in English writing scores for FDC students compared to controls. Furthermore, an interaction analysis reveals a considerable positive impact of method and engagement level on writing skills (p=0.00). English language instructors are encouraged to adopt the FDC method to enhance student engagement and academic achievement in English writing literacy through technology-based learning.
Distribution of rhythmic groups in the paradigm of gender and type of speech activity
Authors: Bankov A. S.
Published: June 2024

This article describes the major results of exploring the contemporary American English particulars of rhythmical groups’ structural types quantity distribution as observed in the course of impromptu speaking and compared with extemporaneous reading, subject to the speaker’s gender. A number of specific features relating both to gender and oral speech production form are discussed. It was found that when switching to impromptu speaking both gender groups show an increase in the number of rhythmical groups of all structural types, however, the specificities of such an increase are different in either group. Women showcase an approximately twofold total gain in the number of rhythmical groups than men. Against the background of the general increase in the number of rhythmical groups of all structural types in a phrase, the Stress Rhythmical Group’s percentage share dynamics in the total gain turned out negative being the only negative indicator for men. With women the negative percentage share dynamics in the total gain is observed in rhythmical groups of two structural types: the Stress and the Proclitico-Enclitic ones. It is noteworthy that both gender groups attest to the same value of the aggregated negative percentage share dynamics in the total gain in the number of rhythmical groups which is equal to -0.8%. The major driving force of the gain in the total number of rhythmical groups is the Enclitic type. However, women evince an approximately 1.5 times greater percentage share dynamics in the gain of the Enclitic rhythmical group than men. Men compensate the reduced Enclitic rhythmical group gain percentage share dynamics by an increase of the indicator in such types as Proclitic and Proclitico-Enclitic. The most rigid structural type of rhythmical groups for women is the Proclitic one, it is also the least numerous for both genders. However, with men, the Proclitic rhythmical group is as agile as the Proclitico-Enclitic one provided, when the latter can be observed almost four times more often than the former. The author makes a number of assumptions and develops several hypotheses about the reasons for these observations, as well as draws possible perspectives for further studies.

Published: June 2024

Objective: The objective of this study is to present a systematic review on the pathogenesis, joint protective mechanisms, and risk factors in osteoarthritis (OA), aiming to provide a comprehensive and updated view that contributes to clinical practice and the understanding of this complex condition.
 
Theoretical Framework: This section presents the main concepts and theories that underpin the research on osteoarthritis. Theories on joint degeneration, protective mechanisms of joints, and associated risk factors are highlighted, providing a solid foundation for understanding the context of the investigation.
 
Method: The methodology adopted for this research comprises a systematic review using a rigorous approach in various biomedical databases, including PubMed, Scopus, and Google Scholar, without language or publication date restrictions. Study selection was based on specific exclusion criteria, focusing on aspects related to pathogenesis, protective mechanisms, and risk factors in OA. Data analysis was qualitative, identifying patterns, trends, and gaps in the literature.

Authors: Rodrigues Junior Manuel Salgueiro , Oliveira Marcelle Colares , Lozano Maria Bélen
Published: June 2024

Objective: The objective of this study is to investigate gender equity, with the aim of analyse the impact of country, sector, and company characteristics on corporate gender equity disclosure.
 
Theoretical Framework: The main concepts and theories that underpin the research are institutional theory with National Business System (NBS) approach.
 
Method: We collected information on gender equity disclosure from 3,726 companies in 58 countries over a 10-year interval from the Thomson Reuters database. Than, we use hierarchical analysis to link the degree of disclosure obtained by companies with variables at the macro, medium, and micro levels.
 
Results and Discussion: We found that the equity disclosure is particularly sensitive to company characteristics such as trade union representation, company size or board gender diversity. Country characteristics, such as enforcement capacity, pressure from unions, popular participation, and economic development positively affect gender equity disclosure. The sector does not present statistical significance to explain variations in gender disclosure.
 
Research Implications: These findings show that theoretical aspects of National Business System and multilevel characteristics approaches do provide empirical support to explain gender equity and its disclosure and help to resolve gender issues
 
Originality/Value: This research fills the gap resulting from the lack of multilevel analysis on gender equity disclosure and helps identify which level and characteristics prevail and have the greatest impact. Therefore, the results guide the intervention of different social spheres to promote gender equity.

Authors: Văn Sơn Trần , Tuyet Mai Vu Thi
Published: June 2024

In this study, a membrane bioreactor – MBR system at laboratory-scale was designed to remove sulfamethoxazole (SMX) in water. The system consists of a 8-liter aerobic tank combined with a hollow fiber micro filtration membrane (MF). Influent flow rate of wastewater was 15,84 L/day. Affecting factors to treatment efficiencies (organic pollutants and antibiotics) such as contact time and initial antibiotic concentration were investigated. Experimental results indicated that wastewater with initial parameters COD, NH4+, NO3-, PO43- were respectively 240, 9,4, 37,5, 6,3 mg/L, the treatment efficiencies achieved were respectively at 63,4, 89,7, 78,1, and 79,8%. The removal efficiencies of the wastewater containing SMX (concentrations range from 0,052 to 0,268 mg/L) for COD and NH4+ decreased by 4,2 and10,9% respectively, and for NO3- and PO43- increased by about 4,5 and 7,9%, correspondingly. Overall SMX elimination performance is about 49,7%.
A Conceptual Modeling Approach for Performance of Magnetohydrodynamic Drag During Planetary Entry
Authors: Ali Hisham K. , Nguyen Danny N. , Braun Robert D.
Published: June 2024

Future higher-mass Mars missions present numerous engineering challenges and will require significant technological development, particularly of the entry, descent, and landing systems. One such development concept utilizes magnetohydrodynamic interaction with the plasma created during hypersonic planetary entry for energy generation, drag augmentation, and heat-flux mitigation. In this study, a performance estimation methodology for magnetohydrodynamic drag augmentation during Mars entry compatible with conceptual design is developed. A demonstrative investigation utilizing the developed methodology is then conducted, and simulated trajectory results are presented for various entry vehicles and magnetic field strengths. The study results show potential for significant magnetohydrodynamic drag augmentation during hypersonic entry at Mars, with calculated effective ballistic coefficient- reduction factors of up to 4, across entry vehicles ranging in mass from 70 MT to 4 MT. These results show that magnetohydrodynamic drag augmentation can have comparable impact to significant aeroshell diameter increases and also suggest that it could prove an effective form of drag-augmentation control authority by varying the applied magnetic field.
Small-Data-Driven Multitask Computational Guidance for Constrained Impact
Authors: Luo Haowen , He Shaoming
Published: June 2024

In traditional data-driven deep learning guidance, variations in guidance tasks may result in sharp performance degradation in terms of accuracy and efficiency of pretrained models. However, obtaining a guidance model adaptable to new tasks requires a substantial investment of training data and time. To address this issue, this paper proposes a small-data-driven multitask computational guidance (SMCG) algorithm utilizing a novel gated progressive neural network structure. The SMCG closely emulates the human learning process. Specifically, it progressively acquires knowledge from simple to complex tasks (from easy to difficult), applies previously learned knowledge from old tasks to new ones (reusing old knowledge), and achieves continuous learning for new tasks by adding new columns (sustainable learning). Simulation results demonstrate that SMCG can effectively reuse expertise acquired from previous tasks in new tasks, thereby reducing the required training data and enhancing the adaptability of the guidance model to new tasks.
Efficient Design Methods for Variable-Angle-Tow Composite Toroidal Pressure Vessels
Authors: Daghighi Shahrzad , Zucco Giovanni , Weaver Paul M.
Published: June 2024

Pressure vessels are widely used in various aerospace and automotive applications. For some applications with limited space, spherical and ellipsoidal shapes are less attractive than toroids. Toroidal shapes can be defined as curved, endless hollow shapes that eliminate the need for end caps when used for pressure vessels. This study presents an analytical formulation using lamination parameters for the novel design of toroidal pressure vessels. The proposed design is based on stiffness tailoring by changing the fiber tow trajectories spatially through the structure to suppress the direct stress and strain gradients in the thickness direction, leading to reduced structural weight, defined as bend-free variable-angle-tow (VAT) toroidal pressure vessels. For a toroidal pressure vessel with a fixed geometry, the VAT distribution through the structure to suppress bending is obtained. Subsequently, the bending stresses and strain levels in the designed VAT toroidal pressure vessels are assessed numerically and compared with those of their isotropic and constant-stiffness composite counterparts. Results show that the designed VAT toroidal pressure vessel generates considerably lower degrees of bending than its corresponding isotropic and constant-stiffness composite counterparts.

Authors: Wu Jieer , Zhou Yu , Luo Wenchen , Song W.-G. , Han Xiao
Published: June 2024

A numerical algorithm that effectively solves the Abel integral equation in laser-induced plasma spectroscopy is introduced. The proposed algorithm utilizes a barycentric interpolation and a collocation method with second-kind Chebyshev nodes. This approach reduces the Abel integral equation to a linear system of equations, resulting in efficient approximate solutions. Analytical studies provide an error estimation for the proposed method, which further validates its effectiveness. Through numerical experiments, we demonstrate the ease of implementation and showcase the efficiency of the proposed method. Our results indicate that the proposed algorithm can provide valuable insight for researchers in the field of laser-induced plasma spectroscopy and beyond.

ESCOLHAS TRÁGICAS E O ESTADO:
Authors: LEITÃO ANDRE STUDART , Schilling Ferraz Taís , Menezes Brunetta Cíntia
Published: June 2024

A complexidade do fenômeno da judicialização da saúde conduz o juiz, constantemente, ao palco das escolhas trágicas. Espera-se que ele decida a favor daquele que pede o direito, para quem o bem jurídico não tem preço, ou a favor do Estado, que, para prover direitos sociais, precisa fazer alocação ou realocação de recursos sabidamente finitos. O artigo investiga, em perspectiva sistêmica, a atuação do Poder Judiciário nas ações sobre direito à saúde, para avaliar a hipótese de que o tratamento atomizado dos casos possa estar retroalimentando a judicialização. Adotando abordagem crítico-metodológica, com base em dados e tomando como referencial teórico elementos da análise econômica do direito, da teoria das escolhas trágicas e do pensamento sistêmico, o texto identifica algumas consequências da forma reativa de atuação judicial no tratamento das ações sobre saúde e avalia, com apoio na teoria econômica do second best, um modelo de atuação que melhor prestigia a capacidade institucional do Poder Judiciário na pacificação de controvérsias e que acolhe a complexidade envolvida na implementação do direito à saúde. Propõe, ao final, o uso mais disseminado das demandas estruturais como alternativa para obtenção de maior ganho sistêmico e sustentável na atuação judicial.

Exploring Intercultural Communicative Competence and Willingness to Communicate of Korean elementary students in Online Intercultural Exchanges
Authors:   The Korea Association Of Primary English Education, Choi Seoyong
Published: June 2024

The present study investigates the effects of online intercultural exchanges (OIEs)
on intercultural communicative competence (ICC) and willingness to communicate
(WTC) among Korean elementary school students. Previous studies have focused on
OIEs with native English speakers, without considering partners who can manage
constraints such as time differences. Therefore, this study specifically examines OIEs
with Japanese and Indian peers for their applicability and expandability. It aims to
deepen understanding by integrating quantitative and qualitative analyses of the impact
of OIEs on students’ ICC and WTC. For this study, 61 Korean EFL elementary school
students completed an Intercultural Communicative Scale (ICS) survey and a WTC
questionnaire before OIEs. The OIEs were then implemented over ten sessions using
the regular English curriculum. After these sessions, surveys and interviews on
participants’ ICC and WTC were conducted. The quantitative results indicated that
OIEs had a positive effect on the students’ ICC and WTC. Qualitative analysis of
participants’ ICC revealed pedagogical implications across four related topics:
interaction engagement and enjoyment, respect for cultural differences, interaction
confidence, and interaction attentiveness. Furthermore, post-test interviews about
participants’ WTC revealed their active willingness to communicate, voluntary efforts
for communication, and willingness to communicate with non-native partners.
Therefore, these findings suggest that participation in OIEs, even with non-native
partners, can enhance ICC and WTC among Korean elementary school students.

This study implemented an AI program to improve the educational outcomes for
students struggling with English. It focused on quantitatively measuring academic
enhancements and collecting qualitative feedback from elementary students with
English deficiencies who used the AI program. The research began by assessing
the English proficiency of the participants. It then analyzed the academic
progress of these students as they used the AI program. Finally, the study
looked into the educational experiences provided by the AI program to the
students, their parents, and their teachers. Key findings included limited time
devoted to studying English outside of regular school hours and a general late
start in English education among the students. Furthermore, the English
proficiency of participants who used the AI program showed greater
improvement compared to a control group that did not use the program.
Interviews and journal entries from the study indicated that all students who
completed the program were actively engaged and experienced enhancements in
their English capabilities. The feedback highlighted the program's ability to foster
strategic thinking and self-motivation for learning. It also noted that the
program's conversational nature was particularly beneficial for improving
communication skills, especially among introverted students, and that immediate
feedback was crucial for effective learning.

Authors: Bayati Nasibeh , Emtiazi Nikoo , Poopak Behzad , Ghiass Mohammad Adel
Published: June 2024

Objectives

Chronic lymphocytic leukemia (CLL) is linked to a highly variable disease course regarding responses to chemoimmunotherapy and clinical outcomes. Mutations in TP53 and/or deletions in chromosome 17p locus [del(17p)] may lead to loss of a TP53 allele. We investigated TP53 mutations in patients with CLL.

Material and Methods

Thirty patients with CLL, aged 40–84 years, were included. Immunophenotyping of B cells was done using flow cytometry by CD5, CD10, CD19, CD20, CD23, CD49d, CD38, FMC7, and CD200 markers. Bone marrow aspiration and peripheral blood smear examination were also performed. DNA was extracted and sequencing was done using the Sanger method. Structural aberrations were investigated using the FISH method.

Results

TP53 mutations had a frequency of eight cases (23.3%), three of which were missense mutations (37.5%), three were intronic mutations (37.5%), and two were silent mutations (25%). Peripheral B lymphocytes had a mean of 82% with 4.59% prolymphocytes.

Conclusion

Accurate testing for TP53 mutations [TP53 and del(17p) mutations] before every treatment line enables us to make proper therapeutic decisions to improve patient outcomes.
Is PowerPoint killing the art of medical teaching and is the interactive board the way forward?
Authors: Das Nikunja Kumar , Khan Sameena , Patil Rajashri , Mukhida Sahjid
Published: June 2024

In classroom teaching, especially in the medical field, it has made the teaching-learning method very effective. Medical teaching evolves quite rapidly, and the same set of slides becomes outdated very frequently. PowerPoint presentation (PPT) are easily editable and hence save a lot of time while updating. Furthermore, medical teaching (any subject) has a lot of pictures and videos in teaching. These can be quite easily and effectively used in PPT, which is not possible in Chalk and Board. Effective teaching is not only dissipation of information but also about continuity and storytelling. This generally gets affected if someone is over reliant on slides in PPT. In our view, a PPT should have at most 15 – 20 slides for a 1-h lecture. This will allow more time in discussion and less time in slide reads.

Published: June 2024

Badanie przeprowadzone na 155 osobach powyżej 16. roku życia analizowało stosunek do pracy w kontekście wieku i doświadczenia zawodowego. Wyniki wykazały różnice w postrzeganiu pracy jako wartości, źródła utrzymania, obowiązku społecznego, źródła radości, aspektu samorealizacji, źródła statusu społecznego, formy ucieczki od rodziny, wartości rodziny, znaczenia sławy i prestiżu, roli pieniędzy oraz znaczenia rozwoju. Młodsze osoby (poniżej 30. roku życia) traktowały pracę jako wartość samą w sobie, źródło radości, aspekt samorealizacji i formę nawiązywania relacji, nie uznając jej za obowiązek społeczny. Osoby w wieku 30–50 lat przejawiały zróżnicowane podejście do pracy, uznając ją za główne źródło utrzymania, ale mniej jako źródło radości. Osoby powyżej 50 lat częściej postrzegały pracę neutralnie lub negatywnie, a także rzadziej jako źródło radości czy samorealizacji. Niezależnie od wieku rodzina była ceniona, pieniądze miały znaczenie, a sława i prestiż były mniej ważne. Rozwój był uznawany za istotną wartość przez większość respondentów. Badanie dostarcza wglądu w postrzeganie pracy przez różne grupy wiekowe, co ma implikacje dla polityki społecznej i pracodawców

Published: June 2024

В статье рассмотрены вопросы создания и использования новых образовательных технологий и методических систем при изучении темы «Организация и техника связи органов внутренних дел» по учебной дисциплине «Специальная техника органов внутренних дел». Рассматриваются вопросы внедрения в учебный процесс программных средств (продуктов) с целью первоначальной подготовки сотрудника полиции на этапе получения высшего образования. Внедрение предложенных технологий и методических систем позволит значительно уменьшить количество ошибок при организации и проведении учебных занятий по вышеуказанной теме учебной дисциплины.

One of the requirements for a police officer is «The police in their activities uses the achievements of science and technology, information systems, communication networks, as well as modern information and telecommunications infrastructure». This requirement cannot be fulfilled without the professional training of a future employee of the internal affairs bodies (ATS). The existing system and methods in the education of some higher educational institutions of the Ministry of Internal Affairs (MVD) do not fully satisfy the high-quality training of a police officer. This state of affairs should not suit modern society. After all, professionalism and the continued existence of the employee himself, the citizens of society and the state as a whole depend a lot on professional training at the stage of obtaining higher professional education.

Quantum well defect-modified single walled carbon nanotubes are environmentally sensitive nanomaterials with wide-ranging applications in biosensing, imaging, light harvesting, quantum computing, energy storage and catalysis. The most common method for covalent functionalization of nanotubes involves reactions with aryl diazonium salts to generate sp3 aryl defect sites. These reactions typically employ harsh conditions which result in poor control and scalability, and incompatibility with biomaterials. We describe herein a rapid aryl diazonium functionalization reaction wherein hydrogen peroxide functions as a reducing agent. The reaction conditions are mild, enabling the quantum well defect functionalization of nanotubes in aqueous solutions at room temperature, with nitrogen and oxygen gas as the primary by-products. This reaction is compatible with both DNA and synthetic polymer-wrapped nanotubes with no apparent disruption to the wrapping agent. As a result, this chemistry is highly complementary to polymer-based nanotube purification reactions such as aqueous two-phase extraction. The reaction is also compatible with unwrapped SWCNTs and in situ generation of diazonium salts from anilines, enabling substantial scalability and versatility with a greater variety of functional groups. The reaction can be easily monitored in real-time via fluorescence analysis and so can be readily controlled and terminated upon reaching the desired degree of functionalization. Overall, this reaction greatly simplifies the production of covalently functionalized carbon nanotubes, expanding their potential for industrial and biomedical applications.

The potential profile of layered oxides as cathodes for Na-ion batteries can be well tuned by cation doping. Doping typically leads to changes in the phase behavior and the redox chemistry, but the processes and design rules are often unclear, especially at potentials above approximately 4 V vs. Na+/Na. Here, we study by means of synchrotron methods and DFT calculations how Mg- and Sc-doping influences the properties of layered O3-NaNi0.5Mn0.5O2. A strong oxygen redox activity is observed at high voltages and both dopants are found to be effective for decreasing the number of phase transitions and for improving cycle life. When comparing the effect of the dopants, notable differences in the first cycle are observed. While the Sc doping maintains the high voltage plateau, Mg doping causes a more sloping behavior. This difference can be understood from the appearance of a new redox center (arising from the ‘O bound to Mg') having a higher redox potential but being more irreversible compared to the redox activity of ‘O bound to Ni'. The appearance of an additional redox center explains findings obtained for other doped Ni- and Mn-based layered oxides, which also show a sloping potential in the high voltage region.

A heteroleptic [Pd2L2L'2]4+ coordination cage containing a photoswitchable azobenzene-derived ligand catalyzes the Michael addition reaction between methyl vinyl ketone and benzoyl nitromethane within its cavity. The correspond-ing homoleptic cages are catalytically inactive. The heteroleptic cage can be reversibly disassembled and reassembled using 530 nm light and 405 nm light, respectively, allowing catalysis within the cage to be switched ON and OFF at will.

Ionic liquids (ILs) in contact with a charged solid surface are known to form layered solvation structures consisting of alternating cation and anion layers. Understanding the response of these layers to surface charge density is vital for IL-based energy storage systems, but it remains inadequately understood. This is partly due to inconsistent experimental conclusions regarding low surface charge density and scarce experimental results for high surface charge density. Here, we probe the solvation structure of ILs on alkali halide surfaces with varied surface orientations: slightly charged RbI(100) and highly charged RbI(111) surfaces to shed light on the above issues, by employing frequency modulation atomic force microscopy (FM-AFM) with a high spatial resolution. Two commonly used ILs, 1-methyl-1-propylpyrrolidinium bis(trifluoromethylsulfonyl)imide ([C3mpyr][NTf2]) and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C2mim][NTf2]) are selected for this study. On the slightly charged RbI(100) surface, we observe alternating cation and anion layers, diverging from the previously proposed monolayer model for IL/alkali halide(100) interfaces. On the highly charged RbI(111) surface, we find crowded layers, which is hardly observed in commonly used ILs due to typically unreachable surface charge densities in electrochemical IL/electrode systems. Our data experimentally elucidates the response of ILs to surface charge density, being expected to deepen our understanding of IL solvation structures on charged solid surfaces. Specifically, observing multilayers on alkali halide(100) surfaces could reconcile some controversial results regarding low surface charge density, whereas detecting crowded layers on alkali halide(111) surfaces offers a new platform for exploring the crowding phenomenon.

Background: In the context of rising obesity rates globally, understanding the effect of high body mass index (BMI) on breast cancer characteristics is crucial. Previous research has hinted at associations between obesity and some specific features, such as tumor receptor status and axillary lymph node involvement. However, a comprehensive investigation into these relationships is essential for informing targeted interventions and advancing our understanding of breast cancer in the context of obesity. Objective: To investigate the relationship between high BMI and some key tumor characteristics such as hormone receptor status, HER2 receptor status, tumor grade, tumor size and axillary lymph node status. Patients and Methods: A retrospective analysis of the medical records of 186 female breast cancer patients treated at Rizgary Teaching Hospital's Oncology Department in Erbil City during the year 2021. Results: The study revealed a statistically significant association between elevated BMI and certain pivotal breast tumor characteristics, particularly HER2 receptor status. Additionally, obese individuals exhibited a significantly greater probability of having axillary lymph node-positive disease compared to their non-obese counterparts. Conclusion: This study establishes a noteworthy association between high BMI and some critical breast cancer characteristics, which may underscore the clinical relevance of body mass index in shaping breast cancer profiles. Keywords: Body mass index (BMI), breast cancer, tumor characteristics.
