Md. Nazmul Haque, Rafsan Mahi & Muhammad Tipu Sultan — Wed, 01 May 2024 00:00:00 +0000

This study delves into integrating sustainability practices within industrial operations, uncovering this endeavor's pivotal motivations, strategies, challenges, and critical success factors. Through qualitative case studies across varied sectors, the research reveals a complex interplay of intrinsic motivations—including environmental stewardship, economic incentives, and stakeholder pressures—that drive companies towards adopting sustainable practices. Operationalizing sustainability emerges as a multifaceted effort, with companies employing diverse strategies that range from incremental improvements to radical transformations aligned with circular economy principles. However, persistent barriers such as entrenched operational practices, financial considerations, and supply chain complexities underscore the significant challenges. The key to overcoming these obstacles is the unwavering commitment of leadership and fostering cross-functional collaboration, highlighting the essential role of strategic vision and organizational alignment in successful sustainability integration. This investigation enhances our understanding of sustainability in industrial contexts and sets the stage for further exploration into effective integration strategies, offering valuable insights for academics, practitioners, and policymakers alike.

IMPACT OF 5G TECHNOLOGY ON SATELLITE COMMUNICATION: A PARADIGM SHIFT IN TELECOMMUNICATIONS WITH A FOCUS ON CYBERSECURITY CHALLENGES AND SOLUTIONS

Md Farad Ahmmed, Abdullah Al Baki Abdullah, Waladur Rahman & Jabed Tarek — Mon, 13 May 2024 00:00:00 +0000

This review investigates the transformative impact of 5G technology on satellite communication, with a particular focus on the cybersecurity challenges introduced by this integration. An analysis of 50 rigorously selected scholarly articles demonstrates that 5G significantly enhances satellite communication by improving data transmission rates, reducing latency, and increasing network efficiency, thereby facilitating extended coverage that bridges the digital divide by delivering high-speed internet to remote areas. Additionally, 5G supports the deployment of new applications such as enhanced Mobile Broadband (eMBB) and extensive Internet of Things (IoT) connectivity. However, this integration also introduces new cybersecurity challenges, such as increased vulnerability to cyber-attacks and the need for robust encryption methods to secure data transmissions. Technical issues like signal interference, regulatory hurdles involving spectrum sharing, and substantial economic investments for infrastructure development also pose significant challenges. These complexities require ongoing research and strategic planning to mitigate risks and fully harness the potential of 5G-enhanced satellite networks. The study highlights a paradigm shift in satellite communications, propelled by 5G's capabilities to create more inclusive, efficient, and secure global communication networks.

COMPARATIVE ANALYSIS OF BUSINESS MODELS IN RETAIL: FAST CYCLE VS. LONG-TERM SUSTAINABILITY

Md Rohul Amin — Mon, 13 May 2024 00:00:00 +0000

This study conducts a comprehensive comparative analysis of fast-cycle and long-term sustainability business models in the retail industry. Through a mixed-methods approach, incorporating both quantitative and qualitative data, this research examines the key characteristics, underlying mechanisms, and impacts of these two contrasting models. The findings reveal stark differences in supply chain structures, design and production processes, marketing strategies, and consumer behavior. While fast-cycle models excel in speed, affordability, and trend responsiveness, they are associated with environmental degradation, ethical concerns, and a culture of disposability. Conversely, sustainable models prioritize ethical sourcing, environmental responsibility, and long-term value creation, but face challenges related to cost, scalability, and the need to balance timelessness with trend relevance. The implications for retailers, policymakers, and consumers are discussed, with a focus on the potential for hybrid models that combine elements of both approaches. This research contributes to the growing body of literature on sustainable business practices and provides valuable insights for retailers seeking to navigate the complex landscape of consumer preferences and sustainability demands.
