Evaluating the Impact of Innovative Learning Management System Features on Student Engagement: A Comparative Study
Samarasinghe, DMIC; Kawya, MVT
Learning Management System (LMS) is a highly accessible platform for individuals
involved in remote learning and remote work, facilitating a seamless environment
for both education and professional tasks. Most of the current LMS systems contain
rudiments that motivate students toward education and encourage them to work at a
veritably minimum position. Thus, most of the students use the LMS only to study
their courses and upload their assessments. The aim of this research is to motivate
and ameliorate students, educational situations using LMS. However, once an LMS
system is in place, it should greatly contribute to the quality of students’ education and
their educational conditioning. This research paper examines the functions that should
be included in an LMS system and the functions that should be updated in an LMS
system for the sake of the educational quality and educational provocation of scholars.
And using a simple questionnaire, data has been gathered and considered them in
order to derive functions like, GPA tracking, Assignment alert feature, Generating a
monthly attendance report and an Academic calendar. The common approach used
in exploration to collect data was a questionnaire and dissect it using expansive and
relative styles. Based on the research data, it appears that a high number of students
prefer the idea of having a Learning Management System with new updated features.

This study conducts a systematic review and evaluation of web-based project management
systems to identify their features, strengths, and weaknesses in order to assess their
suitability for Sri Lankan Online Micro-entrepreneurs. Therefore, this acts as a guide for
Sri Lankan micro-entrepreneurs when choosing the most suitable project management
system for their enterprises. Moreover, this study produces recommendations for future
developments that can address the needs in the Sri Lankan micro-entrepreneurial arena.
When considering academic literature focused on the use of project management tools
and techniques in the performance of organizations, there exists a considerable research
gap, because most of them are conducted regarding large firms, leaving a larger gap
to explore this aspect in the context of Small and Mid-Sized enterprises. So, this
study intends to address that gap. By reviewing the existing academic literature and
conducting surveys using Sri Lankan online micro-entrepreneurs, this study assesses the
suitability of five selected web-based project management systems for the Sri Lankan
online micro-entrepreneurial context. As this study implies, Sri Lankan online microentrepreneurs
face some challenges when adopting project management systems to
their operations. As various web-based project management systems possess diverse
characteristics, it is possible to evaluate the systems and choose the best fitting webbased
project management system for micro-entrepreneurial digital ventures, and this
study provides a contribution to that evaluation process.

A Comprehensive Review on Augmented and Virtual Reality Technologies in Forensic Science: Technology Overview, Applications, and Challenges
Kumarannahe, GN; Wijesinghe, PRD
Forensic science plays a crucial role in the criminal justice system by analyzing evidence
collected from a crime scene. Accurate evidence forms the foundation for a fair
legal system. Most on-site records in traditional crime scene investigations rely on
photographs and manual sketches, which can overwhelm the jury in a court setting.
In need of a more objective, precise, and comprehensive solution for crime scene
documentation, 3D reconstruction of crime scenes for various purposes such as learning
and teaching, courtroom representation, evidence annotations, and visualization has
been trending in forensic science. Integrated 3D scanning platforms could be used
to obtain evidence from the crime scene and these data can be visualized in 3D with
VR headsets which allow respective personals to move through the crime scene and
explore different perspectives. This data can also be preserved and transmitted easily
when needed. This study reviews the technology used, applications of Virtual Reality
and Augmented Reality in forensic science, and the challenges they face in using it.
Key challenges such as medical conditions, cost, data security, and data accuracy
are discussed and future research development areas such as scalability and storage
management of crime scene multimedia data, implementing low-cost high precision
solutions, use of blockchain-based techniques for secure file sharing and adoption
of immersive technology has been suggested. Important reliable academic database
sources were investigated as potential data sources, including Scopus and Google
Scholar, which index publications and conferences supported by organizations like
IEEE, ACM, Elsevier, and SpringerLink.

Quantum Cryptography: Enhanced Security for Better Communication
Kariyawasam, KBMH; Abeysinghe, DVDS
This review extensively explores and compares classical cryptographic methods with
a specialized emphasis on Quantum Key Distribution (QKD) techniques in quantum
cryptography. It thoroughly examines their security foundations, key distribution
mechanisms, vulnerabilities, and implications in modern computing. While revealing
vulnerabilities within classical methods, notably in key distribution and susceptibility
to evolving quantum threats, this review places a significant focus on the intricate
nuances and diverse techniques within Quantum Key Distribution. It highlights QKD’s
theoretical invulnerability, its diverse methods for secure key exchange, and its resistance
against quantum attacks, underscoring its pivotal role in quantum cryptographic
frameworks. This assessment points up classical cryptography’s vulnerabilities amidst
advancing computing power and interception during key exchange. Conversely, it
underscores the resilience of Quantum Key Distribution against quantum-based threats,
presenting diverse methods for intrusion detection. By delving deeply into Quantum
Key Distribution techniques, this review underlines their potential to revolutionize
secure communication paradigms. Rooted in quantum principles, these techniques
pave the way for enhanced security, delineating a transformative path in securing future
communications.
