 Abstract

This paper presents the design of an automatic door system using a rack and pinion mechanism for contactless operation. The system aims to reduce human effort, improve hygiene, and provide convenience, especially for elderly and physically challenged individuals. An ultrasonic sensor (HC-SR04) detects the presence of a person and sends signals to the Arduino UNO, which acts as the control unit. Based on the input, the Arduino controls the motor driver (L298N) to operate a DC gear motor. The motor's rotational motion is converted into linear motion through the rack and pinion mechanism, enabling automatic door opening. When no object is detected, the system reverses the motor to close the door. The system is simple, cost-effective, reliable, and suitable for use in homes, offices, hospitals, and public places, demonstrating the practical application of automation in daily life.

The world of trade is getting more complicated and uncertain. This has changed the role of Incoterms from being about delivery terms to being important tools in logistics and supply chain management. This study looks at how Incoterms 2020 used in the export and import industry. It focuses on how they affect the efficiency of operations, transparency of costs, allocation of risks and customer retention in freight forwarding. The Indian logistics environment is complex with laws like the Customs Act and Goods and Services Tax. This makes it necessary for companies to make decisions about trade terms. This study uses a research design and case studies to evaluate real-world shipment scenarios. It highlights problems that happen when Incoterms are not chosen correctly. For example using EXW can lead to a lack of control over documents. Using CIF can lead to costs. Not having insurance coverage for high-value air shipments can be a problem. Losing input credit for GST under DDP transactions can also be an issue. The study shows that using terms like FCA, CIP and DAP can help companies control logistics processes better. It can also make costs more transparent. Reduce financial and operational risks. By combining expertise with digital tools and regulatory awareness logistics providers can make Incoterms more valuable to their customers. This can help build trust and retain customers. The study concludes that using Incoterms strategically is key to achieving excellence, financial efficiency and a competitive advantage in the global logistics landscape.

 Abstract

Background: Transgenders are individuals whose gender identity differs from sex they were assigned at birth. Transgenders experience high levels of discrimination in health care, partly due to health care provider's knowledge, attitude and practices. Materials and Methods: A descriptive research study was conducted among 101 registered nurses working at AIMSR-GGH, Chittoor Dist. (A.P), India and selected through purposive sampling technique. The data were collected online by administering demographic data tool and self-structured questionnaire tool to explore the nurses' knowledge, attitude and practice regarding transgenders health care. Descriptive statistics such as frequency, percentage, mean & standard deviation were used to analyse demographic variables and the inferential statistics such as Chi-square test were used to find association between knowledge, attitude and practice towards healthcare needs of transgenders among nurses with selected demographic variables. Results: The study findings revealed that, majority of Nurses were in the age group of < 30 years ( 54, 53.5%), females (100, 99%), with B.Sc. Nursing qualification (51, 50%), married (78, 77%), working as a Nursing Officer (78, 77%), having an experience of > 6 years in nursing service (40, 40%), not attended any classes on transgenders and their issues during their academic life (73, 72%) and not knowing any transgenders personally (86, 85%). The study also showed that, majority of nurses had inadequate knowledge (56, 55%), positive attitude (86, 85%) and average level of practice in transgenders health care (55, 54%). Statistically significant association was found between area of residence, current designation, and with the level of Knowledge, Attitude & Practice in transgenders health care among nurses (p = < 0.05). Conclusion: Nurses in this study perceive gaps in their knowledge, attitude and practices that hinder their ability to deliver quality, patient-centred care to transgenders, despite their best intentions.

 Abstract

Digital transformation has become a necessity in the more interconnected global economy of today, where operational efficiency, gaining a competitive edge, and driving innovation have become the driving forces behind the growth and advancement of modern corporate organisations. Despite the fact that technologies such as cloud computing, artificial intelligence ( AI ), the Internet of Things ( IoT ), and big data analytics offer unprecedented opportunities to expand business activities, they are associated with a broad spectrum of cybersecurity threats that need to be carefully planned and properly managed in terms of risk. This paper examines the interplay between digital transformation and cybersecurity in the business environment, considering the key risk factors, organizational governance, and obstacles to the implementation process. This article provides evidence-based recommendations to organisations that are in the process of digital transformation but are keen on strong security practices. According to the research, successful digital transformation is not only a matter of technology, but also requires the implementation of security at all stages of the process, supported by an appropriate governance structure, qualified personnel, and alignment of organisational culture. When companies make cybersecurity a key component of their digital strategy rather than an appendix, they achieve better outcomes in terms of innovation and risk management.

 Abstract

Cryptocurrencies have evolved from a niche technological innovation into a significant component of the global financial system. Initiated by Bitcoin in 2009, and later expanded through platforms like Ethereum, these decentralized digital assets operate on blockchain technology, enabling secure, transparent, and peer-to-peer transactions without reliance on central authorities. This study examines the economic impact of cryptocurrencies, focusing on their role in promoting financial inclusion, driving investment, and fostering technological innovation, while also highlighting risks such as market volatility, regulatory uncertainty, and threats to monetary stability. The paper further explores the regulatory challenges faced by governments and financial institutions worldwide, as they attempt to balance innovation with investor protection and financial security. A comparative analysis of regulatory approaches in major economies--including the United States, India, China, and the European Union--reveals significant inconsistencies and policy gaps. Using a qualitative, descriptive methodology based on secondary data sources, this study identifies how fragmented regulatory frameworks and lack of global coordination hinder the sustainable growth of the cryptocurrency ecosystem. The findings suggest that a flexible, transparent, and internationally coordinated regulatory approach is essential to maximize the benefits of cryptocurrencies while minimizing associated risks. The study concludes by emphasizing the need for adaptive policy frameworks that can keep pace with the rapidly evolving digital financial landscape.

 Abstract

The automotive industry is one of the largest contributors to global resource consumption, carbon emissions, and waste generation, necessitating a fundamental shift in design and production philosophies. This paper examines the integration of circular economy (CE) principles into automotive design as a pathway toward sustainable vehicle production. Through a comprehensive literature review spanning 35 peer-reviewed studies, combined with qualitative and quantitative research methodologies including industry interviews, surveys, and life cycle assessment (LCA) frameworks, this study evaluates the feasibility and impact of CE-based strategies across the full vehicle lifecycle. Key areas of investigation include material recycling and reuse, design for disassembly (DfD), modular vehicle architecture, sustainable manufacturing technologies, end-of-life vehicle (ELV) management, and the development of sustainable battery solutions for electric vehicles. The study identifies critical research gaps in standardised recycling processes, scalable closed-loop supply chains, and economic models supporting circular transition. Findings suggest that embedding CE principles from the design phase significantly reduces raw material dependency, minimises waste generation, and lowers lifecycle carbon emissions -- delivering a 34.5% reduction in global warming potential under the circular model -- while simultaneously offering economic benefits through resource efficiency and remanufacturing. Policy recommendations and industry collaboration frameworks are proposed to accelerate the adoption of circular practices. This research contributes a structured boundary condition framework and actionable guidelines for automotive manufacturers, policymakers, and sustainability practitioners committed to transitioning toward a fully circular automotive ecosystem.

 Abstract

This study examines whether retelling myth actively contributes to cultural evolution or merely reproduces the same narratives again. It argues that myth persists because the flexibility in its structure rather than its preservation. The study focuses on two cases - the Ramayana and the Varaha avatar within Vaishnava mythology. Drawing from comparative myth analysis and A.K. Ramanujan's framework of "tellings", the study shows that narrative and ontological variability are inherent features of mythic continuity. The Ramayana illustrates a continuing shift in narratives depending on region, devotion, performance, and ideology. For example, Rama's gradual divinization, and the shift to a symbol of morality, can be seen from ancient texts to tribal, vernacular, and sectarian texts. A similar examination of the Varaha avatar reveals ontological fluidity. The Varaha avatar takes many iconographic forms, such as zoomorphic, anthropomorphic, and Yajna forms, while maintaining a cosmological significance of destabilization, descent, correction, and restoration. In the initial Vedic texts, the Varaha form takes a more cohesive religious connotation. Building on these findings, the study introduces a speculative reinterpretation of Varaha - The Deep Foundation - as a conceptual test of the adaptability of myths. This reimagining stretches the structure of Varaha to include a higher-dimensional infrastructural ontology. It maintains cosmological functionality of the original myth but removes the anthropocentric aspects. Critical evaluation of the reimagining demonstrates that identity of a myth remains intact even with radical reinterpretations. The results suggest that retelling functions as cultural production, and not distortion. Mythic identity uncovers underlying potential meanings when reinterpreted with coherent cosmologies. In fact, reinterpretation does not undermine tradition; it emphasises the depth and strength of mythic systems.

 Abstract

The present study investigates the determinants of social learning among university students in Lucknow, with specific reference to their academic stream and economic status. A sample of 200 students was selected from various universities using an appropriate sampling technique. The study aimed to examine whether differences in social learning exist across study streams (such as arts and sciences) and across varying economic backgrounds. Data were collected using a self-made social learning scale and analysed using appropriate statistical techniques. The findings revealed a significant difference in social learning among students with respect to both academic stream and economic status. Students from different streams exhibited varying levels of transformative, associative and learning through artificial intelligence, while economic status also influenced access to learning resources and social exposure. The study highlights the importance of socio-academic factors in shaping social learning and suggests the need for inclusive educational practices.

 Abstract

In the vibrant tapestry of Indian spirituality the oral narratives of Bulleh Shah and Guru Nanak Dev have been a guiding force which flourished as tales of unity, love and divine connection. Over time traditional stories shift from oral to written mode. Despite that oral narrative presents a wholesome picture of the social acceptance, rejection and reaction to the sufi Philosophy in the region of Punjab. Focusing on Bulleh Shah and Guru Nanak Dev's twin message of loving relation between devotee and God and emphasized on individual's devotion and worship of God rather than orthodox practices of elaborate sacrifices. Bhakti and Sufi movements sprung as socio religious movements which got popularity from their oral tradition. In the oral recitation of these spiritual Narratives, communities find a sense of belonging and cultural unity. The amalgamation of spirituality, oral narrative of Sufi-mysticism become a conduit for embracing a connection to cultural and spiritual roots. Oral narrative of these two act as a living tradition resonating through the voice of those who continue to adapt their verse. This paper will focus on exploring the profound oral tradition emphasizing their specific relevance in the context of contemporary India spirituality and wisdom.The objectives here are to look into the traces of oral narrative within the selected spiritual verse of Bulleh Shah and Guru Nanak Dev. It will throw light on how their narratives serve as a spiritual guidance cultural unity in the diverse and dynamic setting of India.
