 Abstract

Customer satisfaction is a critical factor in the e-commerce industry that affects consumer behaviour, brand loyalty, and market dynamics. This study looked at the main factors influencing customer satisfaction, including customer service, return and refund policies, delivery speed, and product quality. This study provides a thorough analysis of consumer expectations and experiences with online shopping by comparing survey data from 148 participants with previous research. According to the findings, customer satisfaction was largely dependent on delivery speed (39.5%) and product quality (46.7%). Even though e-commerce platform satisfaction is generally moderate (3.5/5), problems with payment security (18.9%) and return/refund procedures (26.8%) still exist. Additionally, 34.2% of respondents said they were unhappy with the customer service they received. The knowledge gained from this study will help businesses improve their plans to satisfy evolving consumer needs.

 Abstract

The increasing demand for robust encryption methods in the digital age has driven the development of innovative approaches within cryptographic systems. This project presents a novel cryptographic framework that integrates textual name values and dynamic key generation with advanced non-linear transformations, aimed at enhancing encryption security. To achieve this, the system employs lattice-based cryptography for secure key exchange, utilizing the Number Theoretic Transform (NTT) to facilitate efficient polynomial operations. Coupled with Advanced Encryption Standard (AES) for symmetric encryption, the framework incorporates a unique character-to-name mapping and dynamically generated S-boxes, which introduce additional layers of complexity to the encryption process. Extensive testing of the system reveals its robustness, highlighted by an average 51.72% bit change during avalanche effect tests, statistically significant key randomness, and strong resistance to differential attacks. This hybrid approach effectively combines post-quantum security features with the efficiency of symmetric encryption, positioning itself as a promising solution for high-security applications across financial, governmental, and personal data protection domains.

The main objective of this project is to develop a "Smart Women Safety Solution using AI & Real-Time Location Analysis" to enhance the safety and security of the women in real-world scenarios. This system leverages Artificial Intelligence (AI) and real-time geolocation tracking to provide proactive safety measures, instant SOS alerts, and smart risk assessment capabilities. The solution includes key features such as SOS alerts, which notify emergency contacts or authorities during distress situations, risk level prediction based on location analysis, and real-time AR Safe Zones, which guide users to the nearest police stations or hospitals using OpenStreetMap. The integration of AI allows the system to dynamically assess safety levels based on various factors such as time, location, and historical crime data. This project utilizes Flask for backend processing, JavaScript for frontend interactions, and a SQLite database to store user information securely. The admin dashboard enables monitoring of registered users and ensures controlled access. By implementing this AI-powered safety solution, the project aims to empower women with instant security assistance, real-time decision-making support, and an overall safer environment in urban and rural areas. This system not only enhances personal safety but also contributes to the broader goal of creating smart, AI-driven solutions for crime prevention and emergency response.

 Abstract

This paper compares The Catcher in the Rye by J.D. Salinger and Kosala by Bhalchandra Nemade, examining their protagonists' alienation. It explores how both texts resist dominant social structures and capitalist modernity through narrative innovation and symbolic frameworks. The study reveals that the protagonists' alienation is not just psychological but deeply ethical and epistemic. Holden's messianic fantasy protects innocence, while Pandurang's cultural withdrawal resists Westernized knowledge. It introduces ethical-symbolic alienation to critique how these novels use literary form to critique their societies' moral and spiritual failures.

 Abstract

Insurance agents often face a unique set of emotional challenges in their day-to-day work, from handling client expectations to meeting strict performance targets. These emotional pressures can influence how they feel about their jobs, their motivation, and how well they perform. This study looks into how these emotional challenges affect insurance agents, especially in terms of their job satisfaction, mental well-being, and connection to their work. It also explores the reasons behind these challenges--like stress, burnout, and lack of recognition--and discusses ways to help agents cope, such as supportive leadership and mental health resources. The findings highlight the importance of creating a positive and understanding work environment where agents feel supported emotionally. When emotional well-being is prioritized, agents are more likely to stay motivated, build better relationships with clients, and contribute to the success of their organization.

 Abstract

This study examines workforce dynamics in quick commerce (Q-commerce), analyzing how operational demands, workplace factors, and organizational strategies impact employee experiences. Through comprehensive research involving professionals across various roles, the study identifies key workforce challenges and satisfaction drivers in this fast-paced sector. Findings reveal that while employees acknowledge the intense nature of Q-commerce operations, they maintain moderate satisfaction levels, with training opportunities and recognition programs emerging as particularly effective initiatives. The research highlights two critical insights: first, mental fatigue and operational pressures represent significant concerns for Q-commerce workers; second, these experiences remain consistent across all employee demographics, including age, experience level, gender, and job function. This consistency indicates that workforce challenges in Q-commerce are systemic rather than specific to particular employee groups. These findings suggest that organizational interventions--particularly those addressing stress management, communication improvements, and skill development--can be implemented effectively as universal solutions across entire workforces. The study provides Q-commerce operators with practical, evidence-based recommendations for developing workforce strategies that balance operational efficiency with employee well-being, offering valuable guidance for this rapidly evolving sector.

 Abstract

Zambia, like many developing nations, faces the imperative of equipping its youth with the skills necessary to thrive in a rapidly evolving global economy. This article focuses on a pivotal component of this endeavor: the acquisition of practical skills within the Zambian secondary education system. We argue that the effective integration of vocational subjects, traditionally focused on hands-on learning, with the principles of Lev Vygotsky's constructivist philosophy of learning, offers a powerful pathway to achieve this goal. Specifically, we examine the potential for a synergistic relationship between practical vocational training and constructivist pedagogy. By moving beyond rote memorization and passive learning, and embracing active, collaborative, and contextualized learning experiences, students can develop a deeper understanding and more robust practical application of skills. This approach enables them to not only master technical competencies but also to critically analyze, problem-solve, and innovate within real-world scenarios. This article will begin by analyzing the current state of vocational education in Zambia's secondary schools, highlighting its strengths, weaknesses, and the challenges it faces in meeting the demands of the modern workforce. This will include an examination of curriculum design, resource allocation, and teacher training. Subsequently, we will explore the theoretical foundations of Lev Vygotsky's constructivism, focusing on key concepts such as the Zone of Proximal Development (ZPD), scaffolding, and the importance of social interaction in learning. We will demonstrate how these concepts can be effectively applied within vocational education settings to foster meaningful learning experiences. The core of the article will then delve into the practical benefits of merging vocational training and constructivist pedagogy. We will explore how this integration can lead to: o Enhanced student engagement and motivation: By making learning relevant and interactive. o Improved problem-solving and critical thinking skills: Through collaborative projects and real-world simulations. o Increased transferability of skills: By connecting classroom learning to practical applications in the workplace and community

 Abstract

The most popular method for giving the medication orally to the body is the oral route. Some restrictions, including inadequate bioavailability, first-pass hepatic metabolism, medication targeting to specific organs, and drug absorption, might make oral delivery challenging. As a result, parenteral, transmucosal, and transdermal routes are recommended over oral ones. Because the intranasal route's temporal profile of drug concentration is similar to that of the intravenous route, it is considered a favourable approach. An innovative method of medicine administration, the in situ nasal drug delivery system, has been developed to improve patient safety and effectiveness. The medication is delivered as a low viscosity solution using in situ nasal gels. When the nasal mucosa comes into touch with it, The polymer undergoes a transformation into gel form. For medications whose oral administration is troublesome because of gastrointestinal discomfort, poor drug absorption, low drug bioavailability, and first-pass hepatic metabolism, the gel formulation via nasal route is suitable. The gel formulation uses a variety of triggered polymers. The current study concentrated on the following topics: commercialised in situ nasal gel products, therapeutic considerations, nasal cavity architecture and physiology, possibilities and problems in nasal drug administration, and numerous assessment factors taken into account during in situ gel manufacture.
