Authors: Glaied Moez , Whiteley Rodney
Published: February 2025

Background/Purpose

The assessment of ankle plantarflexion force is commonly required in athletic performance and clinical rehabilitation settings to assess the integrity of the calf and lower limb musculature. The force generating capacity of the soleus muscle is thought to be important in many aspects of sporting and everyday function. Unfortunately, there are only a few reliable tests describing the assessment of the strength of the soleus muscle, especially in dorsiflexion greater than plantar grade/neutral which mimics ankle joint positions associated with higher ground contact forces. Accordingly, the purpose of this study is to describe the reliability, feasibility, and clinimetrics of a novel test of plantarflexion force in a clinical setting

Methods

Test-retest reliability of a seated isometric plantar flexion strength test performed a minimum of one day apart (maximum of six) using the maximum value of four trials was investigated using a force plate and custom apparatus in 61 volunteer adults (of varying activity levels (Tegner one to ten). Inter-rater reliability (ICC2,1), Bland-Altman, and minimal detectable change values were estimated.

Results

Sixty-one subjects were tested (49 male, 12 female, 39.6±12.6 years, 81.1±13.8kg). Excellent test-retest reliability was demonstrated (ICC2,1)=0.976 [0.97 to 0.98], p<0.001; and minimal detectable change (MDC) was found to be 118N.

Conclusion

Excellent test-retest reliability and a minimal detectable change of 118N (14.8% bodyweight) were demonstrated for this measure of plantar flexion force. MDC data can inform clinical progression and between-limb differences in healthy and injured individuals. Further, these results can be used to explore the clinical importance of the measurement using the instrumentation.

Published: February 2025

Background

While one-legged and two-legged bodyweight squats on unstable and stable surfaces are commonly used during patellofemoral rehabilitation, patellofemoral loading during these exercises is unknown. Understanding how patellofemoral force and stress magnitudes affects different squat variations will aid clinicians in determining how and when to prescribe and progress these squatting types of exercises in patients with patellofemoral pain.

Hypothesis/Purpose

To quantify patellofemoral force and stress between two squat type variations (BOSU squat versus floor squat) and between two leg variations (one-legged squat versus two-legged squat). It was hypothesized that patellofemoral force and stress would be greater in BOSU squat than floor-squat, and greater in one-legged squat than two-legged squat.

Study Design

Controlled laboratory biomechanical, repeated-measures, counterbalanced design.

Methods

Sixteen healthy participants performed one-legged and two-legged BOSU and floor squats. Kinematic and ground-reaction force data were used to calculate resultant knee force and torque using inverse-dynamics, with electromyographic data employed in a knee muscle model to predict resultant knee force and torque at every 10° between 10°-100° knee-angles during the squat-descent and squat-ascent. Repeated-measures 2-way ANOVA (p < 0.01) was employed for statistical analyses.

Results

Collapsed across one-legged and two-legged conditions, patellofemoral joint force and stress were significantly greater during floor squats than BOSU squats at 40°, 50°, and 70° knee-angles during squat descent and 60° and 50° knee-angles during squat ascent. Collapsed across BOSU and floor squats, patellofemoral joint force and stress were significantly greater for one-legged squats than two-legged squats at all knee-angles. Significant interactions between squat types and leg conditions were found at 30°, 40°, 50°, 60°, and 100° knee-angles during squat-descent, and 100°, 90°, 80°, and 70° knee-angles during squat-ascent, with patellofemoral joint force and stress significantly greater in two-legged floor-squat than two-legged BOSU squat, but no significant differences between one-legged floor-squat and one-legged BOSU squat.

Conclusions

Squatting progression employing lower to higher patellofemoral loading over time during PFP rehabilitation may be considered: 1) two-legged BOSU squats at lower knee angles (0° - 50°); 2) two-legged floor squats at lower knee angles (0° - 50°); 3) one-legged BOSU and floor squats at lower knee angles (0° - 50°); 4) two-legged BOSU squats at lower and higher knee angles (0° - 100°); 5) two-legged floor squats at lower and higher knee angles (0° - 100°); 6) one-legged BOSU and floor squats at lower and higher knee angles (0° - 100°).

Authors: Meireles Adriano Fontineles , Barros Ivanna Leônia Azevedo , Carvalho Maria Raimunda de Lima , Santana Isis Terezinha Santos de , Jankowitsch Jhonata , Pinheiro Weider Silva , Costa Robson Antonio Tavares
Published: February 2025

Introdução: O transtorno de déficit de atenção e hiperatividade (TDAH) tem sintomas que, durante muito tempo, foram pouco compreendidos, em parte devido à falta de estudos aprofundados e por se tratar de um transtorno que não apresenta sinais físicos visíveis. No entanto, pesquisas recentes têm indicado que a alimentação pode impactar diretamente a qualidade de vida de pessoas com TDAH, com nutrientes específicos contribuindo para a prevenção e o manejo dos sintomas do transtorno.
 
Objetivo: O presente estudo busca entender como a Neuronutrição pode contribuir para o manejo e a prevenção dos sintomas do TDAH em crianças e adolescentes.
 
Método: Foi realizada uma pesquisa de campo com dois grupos distintos de participantes: o primeiro, composto por profissionais que atendem crianças e adolescentes diagnosticados com TDAH, e o segundo, por pais ou responsáveis das crianças/adolescentes. A coleta de dados ocorreu por meio de um questionário específico, contendo 10 perguntas direcionadas para cada grupo. A análise foi conduzida de forma quanti-qualitativa, para oferecer uma visão ampla e detalhada sobre a percepção dos participantes quanto ao papel da alimentação no controle dos sintomas do TDAH.
 
Resultados: A pesquisa revelou que, embora a frequência de refeições entre as crianças e adolescentes com TDAH seja considerada adequada, o conteúdo nutricional delas não supre as necessidades para prevenção e controle eficaz dos sintomas. Além disso, poucos profissionais envolvidos no atendimento desses pacientes têm especialização ou conhecimento suficiente sobre estratégias alimentares que poderiam ajudar na redução dos sintomas. Isso indica uma carência de formação voltada à Neuronutrição, o que afeta a capacidade dos profissionais de orientar e monitorar adequadamente os pacientes e suas famílias.
 
Conclusões: A Neuronutrição desempenha um papel significativo no manejo e prevenção dos sintomas do TDAH em crianças e adolescentes. A inclusão de refeições ricas em nutrientes e vitaminas e a exclusão de alimentos com altos teores de açúcar, conservantes e corantes parecem beneficiar o desempenho cognitivo e o comportamento dessas crianças. Há uma necessidade de aprimoramento na formação dos profissionais que atendem esse público, para que possam fornecer um acompanhamento especializado e contribuir para a qualidade de vida dos pacientes com TDAH.

Authors: Ribeiro Fabrício Souza , Silva Valdirene Ramos da , Jankowitsch Jhonata , Costa Robson Antonio Tavares
Published: February 2025

Introdução: A crescente relevância da felicidade corporativa e seus impactos no bem-estar, produtividade e satisfação dos colaboradores reflete sua importância para a eficiência organizacional e a retenção de talentos.
 
Objetivo: O estudo teve como objetivo explorar as relações entre fatores organizacionais e o bem-estar no ambiente de trabalho de um cartório em Goiás, com foco na felicidade corporativa e na saúde mental dos colaboradores.
 
Método: Os dados foram coletados por meio de um questionário estruturado em escala Likert de 5 pontos, aplicado a 72 participantes. A análise estatística foi conduzida utilizando o coeficiente de correlação de Pearson para examinar as associações entre variáveis.
 
Resultados: Os resultados indicaram fortes correlações positivas entre estresse no trabalho e melhorias no ambiente (r = 0,77), suporte contra estresse e saúde mental (r = 0,71), e critérios de meritocracia e reconhecimento (r = 0,75). Contudo, observaram-se correlações negativas moderadas entre desenvolvimento profissional e melhorias no ambiente (r = -0,32), sugerindo a influência de variáveis externas. Surpreendentemente, a remuneração foi considerada menos relevante para a felicidade no trabalho, contradizendo a literatura existente.
 
Conclusões: Conclui-se que, embora o ambiente de trabalho mostre práticas positivas para promover o bem-estar, o aumento do estresse e as contradições nas respostas sugerem a necessidade de estratégias mais eficazes para mitigar fatores negativos. Recomenda-se uma avaliação interna contínua para compreender melhor os impactos das mudanças organizacionais e implementar melhorias que promovam saúde mental e satisfação.
Health promotion and tobacco control: a transatlantic perspective between Brazil and Portugal
Authors: Fontes Francisco Lucas de Lima , Caldeira Ermelinda do Carmo Valente
Published: February 2025

Health promotion, a concept based on the Ottawa Charter, recognizes that health is influenced by economic, social and environmental factors, as well as individual practices. The fight against smoking is one of the most challenging fronts in this context, given its direct relationship with the global burden of chronic diseases and preventable deaths. The articulation of public policies that involve multiple sectors and civil society has proved fundamental in dealing with this problem. In both Brazil and Portugal, health promotion plays a crucial role in integrating tobacco prevention and control actions, reflecting the guidelines of Canada's Population Health Promotion Model.
This Canadian model highlights the intersection between health, public policies and community action, emphasizing the need for healthy environments and structural interventions that shape behaviour. The influence of this paradigm is evident in global policies, including those adopted in Brazil and Portugal. It offers a theoretical framework that guides governments to create evidence-based strategies that are sensitive to cultural and social particularities. In Brazil, the National Health Promotion Policy (Política Nacional de Promoção da Saúde, PNPS) translates these principles into concrete actions, whereas in Portugal, the National Program for the Prevention and Control of Smoking reflects a progressive normative approach, especially in relation to tobacco consumption and electronic devices.
Brazil and Portugal have different histories and cultural dynamics, but they share similar challenges in tackling smoking. In Brazil, robust policies have contributed to a significant reduction in the prevalence of adult smokers, from 34.8% in 1989 to 12.6% in 2019(1). These achievements are the result of educational campaigns, tax increases and the creation of smoke-free environments. In Portugal, legislative efforts, such as the Tobacco Law (Law No. 37/2007), have significantly limited smoking in public places and restricted advertising, but the country still faces worrying rates, with 17% of the population identified as smokers in 2019(2).

Authors: Ikhsan Muhammad , Sukirman Sukirman
Published: February 2025

Myriad of studies have shown that Content-Based Instruction (CBI) has become a widespread approach in EFL settings, particularly in developing students ‘writing and speaking skills since these productive skills need more efforts and persistence. Some considerable strategies have been applied in adopting Content-Based Instruction (CBI) in today's language classrooms. Teachers may apply this approach by asking students to work in groups and ask them to discuss text on selected topics, activate their prior knowledge, and then report the results by restating what they have read in both written and oral performance. These activities could be extended by providing tasks demonstrating students ‘lexical, syntactic, morphological and grammatical knowledge as well. In the workshop, presenters are going to demonstrate how content-based approaches may increase students' motivation, content-knowledge, and independent thinking as well. It is hoped that by applying these approaches, students may develop strategies for collecting, synthesizing, and interpreting new information as this promote students' autonomy as one of the significant principles to meet international standards of language learning.

Published: February 2025

This paper is aimed to describe what knowledge and skills an English teacher should have to be assessment literate. The paper focuses on the following four basic knowledge areas of assessment literacy. First, English teachers should know what assessment is in general and what classroom assessment is. Second, the teachers should know the purposes of assessment. This knowledge will guide the teachers to create general learning goals, construct clear learning targets, and formulate clear rubrics. Third, the teachers should be aware of various assessment methods in ELT. Last, the teachers should comprehend assessment's positive influences in teaching and learning. To have a positive washback of assessment, the teachers should know how to create effective classroom assessments, how to make constructive feedback, how to support the role of students in assessment, and how to modify instruction based on assessments' results. Assessment literacy is an individual's understanding of the basic concepts and procedures of assessment which will be used as a basis for educational decisions (Popham, 2009). To be assessment literate, a teacher should have the knowledge and skills in relation to basic principles of quality assessment. This essay will discuss four basic knowledge areas of assessment literacy: definition of assessment, purposes of assessment, methods of assessment and keys for creating positive washback of assessment that can improve instruction and students' learning.

On the Category of (i,j)-Baire Bilocales
Authors: Nxumalo Mbekezeli
Published: February 2025

We define and characterize the notion of (i,j)-Baireness for bilocales. We also give internal properties of (i,j)-Baire bilocales which are not translated from properties of (i,j)-Baireness in bispaces. It turns out (i,j)-Baire bilocales are conservative in bilocales, in the sense that a bitopological space is almost (i,j)-Baire if and only if the bilocale it induces is (i,j)-Baire. Furthermore, in the class of Noetherian bilocales, (i,j)-Baireness of a bilocale coincides with (i,j)-Baireness of its ideal bilocale. We also consider relative versions of (i,j)-Baire where we show that a bilocale is (i,j)-Baire only if the subbilocale induced by the Booleanization is (i,j)-Baire. We use the characterization of (i,j)-Baire bilocales to introduce and characterize (\tau_{i},\tau_{j})-Baireness in the category of topobilocales.

Authors: Guillén-Jiménez Claudia Marcela , Calderón-Santoyo Montserrat , González-Gutiérrez Katia Nayely , Ragazzo-Sánchez Juan Arturo
Published: February 2025

Las proteínas vegetales han sido empleadas en diversos estudios como material de pared en la encapsulación de compuestos de alto valor biológico, debido a su buena accesibilidad y a la fácil liberación del principio activo. El haba (Vicia faba) es una legumbre con alto contenido de proteínas susceptible de ser utilizada como material encapsulante. Randia monantha contiene compuestos con actividad antifúngica, por lo que su extracción y encapsulación representa una alternativa para poder usarlos en el control post-cosecha de hongos fitopatógenos. El objetivo del presente trabajo fue encapsular por secado por aspersión un extracto etanólico de R. monantha utilizando como material de pared proteína de haba para el control de Colletotrichum gloeosporioides. El extracto se obtuvo mediante extracción etanólica asistida por ultrasonido y se encapsuló usando secado por aspersión con diferentes concentraciones de proteína de haba (15 %, 20 %, 25 % y 30 %). Posteriormente, se evaluó la actividad antifúngica del extracto encapsulado y se realizó la caracterización térmica y fisicoquímica de las cápsulas. El extracto encapsulado con proteína al 30 % presentó la mayor inhibición de la germinación de esporas (65.4 %) y del crecimiento micelial de C. gloeosporioides (55.23 %) y estabilidad a la temperatura y a la radiación UV. Las cápsulas registraron alta eficiencia de encapsulación y solubilidad, con baja actividad de agua e higroscopicidad, características deseables para un producto en polvo. La proteína de haba, como material encapsulante, mostró ser una alternativa prometedora para su uso en el control de C. gloeosporioides, ya que preservó la capacidad antifúngica del extracto de R. monantha, presentó propiedades fotoprotectoras y termoprotectoras y las cápsulas cumplieron con los parámetros fisicoquímicos de un producto en polvo.

Published: February 2025

Dado el continuo avance de la tecnología de impresión 3D y el creciente interés en desarrollar prototipos o productos con propiedades mejoradas, este estudio se centra en la evaluación de las propiedades mecánicas del acrilonitrilo-butadieno-estireno (ABS). Se fabricaron probetas de ABS bajo diferentes condiciones de impresión, las cuales fueron evaluadas mediante un diseño de experimentos y ensayos de tensión para identificar los parámetros óptimos que maximizan la resistencia a la tensión del material. Adicionalmente, se realizó un análisis mecánico dinámico (DMA) para la probeta con mejores condiciones de impresión, evaluando su comportamiento viscoelástico en función de la temperatura. Los resultados del DMA muestran una temperatura de transición vítrea alrededor de 123°C, indicando la máxima disipación de energía. Por encima de los 160°C, el material mostró un comportamiento viscoso asociado al inicio del flujo, información clave para optimizar procesos como la inyección, extrusión e impresión 3D. Este enfoque integral combina técnicas de caracterización mecánica y viscoelástica, permitiendo establecer una relación entre los parámetros de impresión y el desempeño del ABS, contribuyendo al diseño eficiente de procesos y aplicaciones.

Sor Juana Inés de la Cruz propone una reflexión sobre las complejidades de la composición verbal a través de su poema Ovillejos, un homenaje al escritor español Jacinto Polo, donde plantea implícitamente la pregunta sobre cómo escribir poemas que abordan el tópico particular del retrato femenino, poniendo en escena a una pintora en el momento de ejecutar su obra, el retrato de Lisarda que configura un bucle extraño porque muestra a cierta musa la pintura donde ejecuta el retrato mediante la figuración de espacios artísticos. Este poema se desdobla en la puesta en escena de la ejecución de una pintura y al mismo tiempo que busca mostrar el retrato imaginario de una mujer, Lisarda, escribe un poema, a saber, Ovillejos.
Una propuesta estética de lo singular desde las diferencias y la repetición Deleziana
Authors: Rojas Gonzalo
Published: February 2025

Este trabajo propone una idea metodológica hacia una estética de la singularidad, la cual se vincula directamente con los aportes de Gilles Deleuze sobre el pensamiento creativo, a partir de su libro Diferencia y repetición. Dicha propuesta se basa en sistematizar sobre poéticas o escritores asociados a lo que Deleuze menciona como escrituras no saludables. Por lo anterior, esta metodología se inicia desde lo material a lo inmanente, esto es, a través de tres diferencias que van del hábito empírico (diferencia uno) hasta el yo que abraza el destino (diferencia 3), pasando por la memoria singular (diferencia 2)  hasta la repetición como inmanencia de la intensidad estética.
Una macroanalítica de la edición: el caso de LibrosMéxico
Authors: Guerrero Galván Ana Verónica
Published: February 2025

Este artículo explora un enfoque macroanalítico en el estudio de la edición en México a través del preprocesamiento y visualización de datos provenientes de la base de datos LibrosMéxico, utilizada para detectar tendencias en la producción editorial desde 1980 hasta 2022. Inspirado por estudios previos en el campo de la analítica cultural, este artículo emplea datos de plataformas digitales y catálogos comerciales para estructurar un corpus que visibiliza tanto el volumen de publicación de editoriales dominantes como las dinámicas colaborativas de publicación de otras editoriales más pequeñas. Estos resultados, además, son combinados con las observaciones resultantes de una serie de entrevistas semiestructuradas llevadas a cabo con editores mexicanos. En un contexto donde el acceso y el costo de datos sobre la industria editorial siguen siendo limitados, este artículo explora los desafíos metodológicos y técnicos de la esta nueva metodología su potencial para fomentar un conocimiento más inclusivo sobre el sector editorial mexicano.
Los considerados enemigos del cristianismo/catolicismo a través de un semanario de la ciudad de Monterrey en 1873
Authors: Salas Martínez Isaac Omar , Herrera Martínez Manuel Santiago
Published: February 2025

Durante la década de 1870, se vivió un proceso de transformación nacional a nivel político, social y cultural en donde corrientes ideológicas como la secularización, el liberalismo y el surgimiento de nuevos cultos religiosos ajenos a la Iglesia cristiana y católica, provocaron un choque de intereses, principalmente, entre aquellos del tipo tradicionales y los que estaban en boga. El presente trabajo de investigación1 trata de analizar cómo dicho contexto histórico se vio reflejado en el ámbito religioso de la ciudad de Monterrey donde el clero vio amenazado su doctrina ante otra nueva ideología. Por medio del semanario “La Luz” intentaba señalar a quiénes consideraba adversos a sus creencias. Esta investigación es de corte histórica y a través del análisis del discurso se examinarán los actantes con sus respectivas expresiones y argumentos para justificar el sentido de pertenencia. Para lograr esto, se tomaron en cuenta las propuestas teóricas de los instrumentos de análisis I y II de la autora Manuela Picazo (2014); los elementos de exclusión en el discurso de Michel Foucault (2005); la teoría de los cinco rasgos de la ideología de Reboul (1986); las falacias tradicionales propuestas por Íñigo Fernández (2016); los Modelos de contexto, creencias en grupo y estructuras ideológicas de Van Dijk (2005), así como su Análisis Crítico del Discurso (2017). Esto debido a que son las principales teorías que permiten conocer a fondo el tipo de ideología del semanario, así como los elementos que emplea para expresar sus inconformidades, temores y señalamiento de aquellos grupos o actores sociales, todo bajo los propios “supuestos” que maneja el medio: sus intenciones, valores, costumbres y acciones que son una amenaza para la religión, su Iglesia y la sociedad misma.

GREEN SOCIAL WORK AND SUSTAINABLE DEVELOPMENT GOALS: GLOBAL TO LOCAL PERSPECTIVES.
Authors: Kumar Vinay , MA Suhel
Published: February 2025

Green social work is an emerging and futuristic concept within the realm of social work profession. It aims to identify the overlaps between ecological issues and social problems, including poverty, inequity, and social exclusion, in light of a rapidly mounting universal environmental crisis illustrated in climate change, disasters, biodiversity loss and pollution. By promoting social and ecological well-being through sustainable practice and in the spirit of environmental justice, green social work aims to initiate balanced development in the social and ecological well-being of individuals, especially the vulnerable groups who are at the periphery of development. Literature in Green Social Work acknowledges the necessity of contesting this scenario in order to integrate completely ecology within social work practice, policy and advocacy for social justice. This article describes the various approaches of the green social work in practice, including its theoretical roots, methods, challenges, and future implementation for lively and sustainable co-existence of human and the environment. Green social work also is aligned with the United Nations Sustainable Development Goals (SDGs) 13 (Climate Action), 10 (Reduced Inequality), 11 (Sustainable Cities and Communities) and 12 (Responsible Consumption and Production) highlighting its contemporary relevance to society and practice at grassroots to complement the SDGs concerns globally.

Authors: Singh Joginder
Published: February 2025

This paper explores the multifaceted economic strategies employed by the Mughal rulers, focusing on land revenue systems, trade, industry, and agriculture. The study delves into the mechanisms of taxation, particularly the land revenue system introduced by Emperor Akbar, and its impact on the agrarian economy. Furthermore, it examines the empire's extensive trade networks, both regional and international, which contributed significantly to its wealth and global influence. Additionally, the role of the Mughal court in fostering the arts, architecture, and industry is considered as part of a broader economic vision. The economic policies of the Mughal Empire, which flourished in the Indian subcontinent from the early 16th to the mid-18th century, played a pivotal role in shaping the region’s economic landscape. This historical perspective highlights the complexities of Mughal economic policies, emphasizing their long-lasting effects on the social and political fabric of India. Through an examination of historical records and scholarly interpretations, this paper aims to provide a nuanced understanding of the economic strategies that underpinned one of the most powerful empires in world history.
A STUDY OF GRASSROOTS DEMOCRACY IN INDIA: ROLE OF PANCHAYATI RAJ INSTITUTIONS
Authors: Nutan
Published: February 2025

This paper explores the role of Panchayati Raj Institutions (PRIs) in the development of grassroots democracy in India. Since their constitutional establishment in 1992, PRIs have been a crucial mechanism for decentralizing power, ensuring local self-governance, and fostering inclusive participation in decision-making processes. This study examines the evolution, functioning, and challenges faced by PRIs at various levels—village, intermediate, and district. By analyzing empirical data, legislative frameworks, and case studies from different states, the paper assesses how PRIs have contributed to democratic deepening, social equity, and empowerment of marginalized communities, especially women and Scheduled Castes. However, it also highlights persistent issues such as inadequate financial autonomy, political interference, and the limited capacity of local leaders. The research emphasizes the need for structural reforms, enhanced capacity-building, and greater empowerment to fully realize the potential of Panchayati Raj as a tool for strengthening grassroots democracy in India. Ultimately, the paper provides recommendations for improving the effectiveness of PRIs in achieving sustainable development and participatory governance at the local level.
APPLICATIONS OF NUMBER THEORY IN CRYPTOGRAPHY
Authors: K Gavirangaiah
Published: February 2025

Number theory is a branch of mathematics that plays a critical role in the field of cryptography, providing the theoretical foundations for many cryptographic algorithms and protocols. It involves the study of integers and their properties, including prime numbers, divisibility, modular arithmetic, and Diophantine equations. Cryptographic systems leverage these number-theoretic concepts to secure communication, protect data, and ensure privacy in digital transactions. One of the most significant applications of number theory in cryptography is in public-key cryptography, which relies on the mathematical difficulty of certain number-theoretic problems. For example, the RSA algorithm, one of the most widely used public-key cryptosystems, depends on the difficulty of factoring large numbers, a problem that is grounded in number theory. Modular arithmetic and prime number theory form the core of RSA key generation, encryption, and decryption processes. Similarly, Elliptic Curve Cryptography (ECC) uses the algebraic structure of elliptic curves over finite fields and relies on the difficulty of solving the Elliptic Curve Discrete Logarithm Problem (ECDLP). Other number-theoretic methods, such as modular exponentiation and the Euclidean algorithm for finding greatest common divisors, are central to the security of protocols like Diffie-Hellman key exchange, which allows two parties to securely share a secret key over an insecure channel. Digital signatures, which authenticate and verify the integrity of messages, also use number-theoretic operations, often involving modular arithmetic and hash functions. In conclusion, number theory is indispensable to modern cryptography. It underpins the security of a wide range of cryptographic protocols and systems, ensuring the confidentiality, integrity, and authenticity of digital communications and transactions in an increasingly interconnected world.
