    An Appraisal of Perception and Preparedness of Higher Education Teachers towards E-Learning Resources and Methodologies
    (Uva Wellassa University of Sri Lanka, 2019) Subramaniya Bharathy, R.; Raja, K.
    Education is the backbone for the development of a nation in long-run. The face of teaching and learning process has changed substantially. The web has become one of the channels of learning that opens the door for people around the world to access education for free, or for fewer costs. Students prefer different types of learning vehicles and independent learning. Interactive learning and self-paced learning fosters the learning among the students. For Higher education teachers, the web-enhanced teaching is no longer an add-on feature in teaching but a necessity. It is the bound duty of the teachers to upgrade themselves to the current trends in teaching and to cope up with the changing technology. Unless otherwise the teachers are ready for the evolution, it is always going to be a distant dream for the students to learn the concepts through e-learning. Moreover, it becomes more important for the teachers to be aware of the latest e-learning tools and methodologies to equip themselves to meet the future demands and needs of the students’ community. Again, the design and implementation of e-learning methodologies largely depends upon the conceptions and perceptions of the teachers. Unless otherwise they have positive opinion and perception about the e-learning, they will not have the right tendency to design and implement the e-learning process. Hence, a study is required to assess the awareness and perception level of the college teachers towards the e-learning methodologies and tools and also to assess their readiness and obstacles in adopting the e-learning methodologies and tools in teaching-learning process. Hence an empirical study titled “An appraisal of perception and preparedness of higher education teachers towards e-learning resources and methodologies” was carried out. For the study, a questionnaire was sent to all 100 affiliated colleges of Periyar University and data were collected from one respondent (Teacher) from each college. Descriptive statistics were used to analyse the data. Results indicated that the majority teachers (88%) are having eagerness and willingness to adopt the e-learning tools and techniques but lack of facilities, incentives; training and institutional supports are preventing them to actively engage in e-learning methodologies.

    E-Business Decision Support System for Online Shopping using MAS with Ontology and JADE Methodology
    (Uva Wellassa University of Sri Lanka, 2019-02) Kannan, K.; Raja, K.; Rajakumar, A.; Nizar Banu, P.K.
    E-Business systems are playing a crucial role in human’s day to day life. It acts as an interface between the product manufacturer and the end users thereby reducing the time and cost. It also offers a variety of choices in products based on product ratings for quality, pricing, and services. The customers of the e-commerce ecosystem can do everything online and even make the payments. Recommender systems suggest/help the customer for shopping the products based on their interest and their usage. JADE (Java Agent Development Framework) is FIPA (Foundation for Intelligent Physical Agents), that enable automated agents to perform intelligent tasks efficiently. JADE is an open Framework with stable and optimal database agents in the distributed environment. MAS (Multi-Agent System) offers the methodologies for the financial transaction in an EBusiness environment. The recent implementation of MAS with the current Web methodologies (JACK, JADE, etc.) serves as the building blocks for the upcoming ecommerce platforms for taking core decisions and negotiations. With the help of AgentOriented Programming Languages, the functionalities/roles in the use cases are created as Agents. Though this domain is growing exponentially, constructing an ontology for a dedicated purpose is a challenging task to define various concepts and actions. Thus, the e-business ecosystem invites fruitful research solutions for time-constrained applications and secure transactions. In this article, we propose a framework that combines the JADE, ontology and Multi-Agent System based web service composition to increase the efficiency of the system with optimal services. Also, our proposed system aims at providing a secure E-Payment under the availability of financial institutions. The proposed framework is tested under different cases and it is inferred that the system will offer an efficient process for the secured and time-saving E-Commerce transactions.

    Effective C-RBAC Framework Based on Role Provisioning for Data Protection in Business Application Systems
    (Uva Wellassa University of Sri Lanka, 2019-02) Auxilia, M.; Raja, K.; Kannan, K.
    Security plays a key role in any business organization for the purpose of information sharing and privacy. However, there is a lack of privacy and safety among the information. Business data and organizational data are considered to be the highly sensitive data because of the impact that may result in the business process. The employees of any organization are the real assets for their concern and it’s the responsibility of the organization should have a clear vision about the activity of all the employees under legal business development. In this article, new RBAC (Role Based Access Control) framework is developed to navigate the process for a particular employee and their services in any business organization. RBAC framework is especially developed to provide security based on role provisioning during information sharing. AgZKPk (Aggregate Zero Knowledge Proof knowledge) and OCBE (Oblivious Commitment Based Envelope) Protocols are used for role enrollment for RBAC concept (condition policies). In this paper, C-RBAC (Cloud– Role Based Access Control) framework is proposed which can fit in any business organization application. In this C-RBAC, PEP (Policy Enforcement Point) is used to avoid unwanted information sharing with the neighbouring employee or peers. The analysis is done based on the security level for several security algorithms in C-RBAC framework. C-RBAC framework with RSA provide well security based on number of employee with the data handled by the particular employee than the existing RBAC framework with AES (Asymmetric Encryption Standard) and RSA (Rivest–Shamir–Adleman) in terms of number of information they can handle per user. Our analysis revels few threats that arise due to sharing of data and violation in agreements. Also, it is inferred that by adopting our proposed framework, we can avoid data leaks and can protect the data even within the organization.

    An Implementable Architecture of E-Library Using Cloud Storage System
    (Uva Wellassa University of Sri Lanka, 2019) Raja, K.; Srinivasan, S.; Subramaniya Bharathy, R.; Kannan, K.; Ponnusamy, P.
    In olden days, the user accessed library information system are complicated due to large database appeared in single area. The need for storing the library information system in digital manner by applying cloud computing. The cloud computing resources, services are completely based on ubiquitous computing. As a result, library patrons can access services from outside of physical library by cloud computing. This paper analyses overview of cloud computing, current trends, standards and proposals for e-library with cloud storage system and possible cloud types. This paper also exposes the research reports and views of various researchers on digital library and its services using cloud concepts. The cloud storage is an innovative revelation of Information Technology of digital world. It contributes an original scheme of a cloud storage functional architecture for building e-library systems. The e-library services makes novel trend in scheme of cloud storage data center with respect to information access and dissemination of cloud computing. The cloud storage functional architecture for digital library is an internet based standard communication which maintains the inter-relationship between user and cloud storage providers. It provides information handling, speedy transfer of e-library information and linking of communication with user and cloud storage provider. It will promote the maturity level from clerical to administrative members that meet client request and recognize the sustainable growth of e-library system. This architecture progressively developed e-libraries knowledge management by means of user involvement. This e-library system using cloud storage implementation makes better data integration, reduced cost, accessible any where any time resources, elasticity, scalability and portability.
