Item Embargo Kube5GC: Kubernetes-Native Orchestration for 5G Core Network(Institute of Electrical and Electronics Engineers Inc., 2025) Wijesekera, T; Jayarathna, L; Pathirana, G; Banu, R; Wickramarathne, JTelecommunications service providers face challenges such as rigid infrastructures, manual configuration, inefficient routing, and security risks, especially in 5G deployments. This paper presents Kube5GC, a Kubernetes-based framework for 5G Core network orchestration. Leveraging Kubernetes orchestration, NFV, and SDN, Kube5GC automates deployments, optimizes resource allocation, and manages network slices with efficiency. Architecture reduces operational complexity and costs through automated, secure, and scalable workflows. Kube5GC integrates CI/CD pipelines via GitOps, deploys containerized 5G functions using Open5GS, and enforces secure inter-service communication with robust secret management. During validation, the platform achieved rapid pod readiness, low latency encrypted traffic, and reliable operation under telecom workloads. Integrated observability with Prometheus, Grafana, and distributed tracing enables comprehensive monitoring of control and user plane metrics, while automated backup and policy-driven configuration management enhance operational resilience. These results confirm Kube5GC as an efficient, scalable, and secure orchestration platform for 5G Core networks in cloud-native environments.Item Embargo Sustainability Insights: Unveiling the Impact of Business Analytics in Shaping Sustainability Practices in the Apparel Industry(2025) Gajanayake, L; Rajapaksha, D; Rukshan, T; Pathirana, S; Thelijjagoda, S; Pathirana, GThe Sri Lankan apparels industry has a strategic importance for the national economy as the country has been one of the main exports and employers. But it has sustainability issues such as high resource consumption, increased pollution, and poor labor standards. As the consumption of sustainable and environmentally responsible clothes continues to rise around the world, such concepts as business analytics (BA) present an opportunity to tackle these issues. This study investigates the effects of BA tools and techniques in enhancing sustainability in Sri Lanka apparel industry with regards to waste reduction, efficient resource management and compliance to ethical standards for sustainable driven global business. A qualitative research design was followed and conventional interviews conducted on key informants from GOTS certified apparel factories. Data were coded and analyzed thematically using MAXQDA software, with reference to the subthemes that emerged in the study, such as waste reduction and increasing efficiency and effective decision-making. It was revealed that BA solutions such as RFID, predictive modelling and dynamic dashboards offered promising improvements to sustainability performance. Techniques like 3D sampling reduced fabric consumption during the generation of prototypes, and dashboard analytics allowed constant tracking of other forms of sustainability KPIs like power use and carbon footprint. They also increased efficiency of cross-functional coordination, integrating sustainability into functions and departments. This study demonstrates how BA enables the sustenance of development within the apparel industry, based on a strategic management of economical, ecological, and social goals. The outcomes would help industry leaders and policymakers in developing improved strategies for sustainability practice to overcome existing gaps between theory and practice and for sustainable and competitive business growth in the context of a world economy moving toward sustainability.Publication Open Access Navigating the Evolving Landscape: A Comprehensive Systematic Literature Review on Generation Z's Expectations for Internal Communication from Leaders to Enhance Employee Productivity(SLIIT Business School, 2023-12-14) Kumarasena, N; Rathnayaka, C; Dayawansha, P; Maduranga, S; Pathirana, G; Ehalapitiya, S; Krishan, G; Kulawardena, RThis systematic literature review delves into the dynamic realm of internal communication between leaders and Generation Z employees, aiming to elucidate the expectations of this emerging workforce and explore strategies to elevate organizational productivity. In an era marked by rapid technological advancements and shifting workplace dynamics, understanding, and adapting to Generation Z's communication preferences becomes imperative for fostering a thriving work environment. This review critically examines existing literature, synthesizes key findings, and proposes insights that leaders can leverage to optimize internal communication practices, ultimately boosting employee productivity in the contemporary workplace.Publication Open Access Systematic Review: The Role of Data Analytics in Enhancing Academic Performance Classroom interaction, Learning Analytics in Higher Education(ICSDB 2024 and SLIIT Business School, 2024-12-10) Sithumini, J.H.C.; Sanjuka, A.N.E.; Ranawaka, P. S.; Hasaranga, H.G. D.; Samarakkody, T.; Pathirana, GThe field of data analytics has seen substantial growth, particularly within the education sector. With the recent expansion of e-learning due to the COVID-19 pandemic, the ability to make data-driven decisions in education has become more important than ever. This review synthesizes existing research on the role of data analytics in enhancing academic performance and decisionmaking in higher education. The key objectives are to examine the influence of data analytics on student performance, explore learning analytics’ role in institutional decision-making, and assess the effect of data analytics on e-learning systems, particularly during the COVID-19 pandemic.
