AN INFORMATION ENABLED WORKFLOW ENGINE
(2010) Weerakoon, W.A.C.; de Silva, C.H.
Today most of the workflows of document/information processes or transactions are managed by the systems build on IT infrastructure of an establishment. Workflow Management can be done best, by fully or partially automated tools that combine human and machine based activities. This paper presents the entire life cycle of the development process of such a partially automated tool, the Document/Information enabled Workflow Engine (WFE) and its integration in to the Content Management Solution (CMS) of a reputed software vender. A workflow engine, the generator and the coordinator of document/information enabled workflows, have been designed, implemented and integrated into the company?s Content Management Solution, as an effort to improve application reliability and availability throughout the enterprise. This approach standardizes the user?s software packaging process provides automated document/information enabled workflows, which can be used for rapid deployment and flexible execution of edocumentation processes thereby tying the people, systems, organizational knowledge and goals to congregate into comprehensive, efficient processes, reducing the administrative overhead. In the development process unified modeling approach has been used, which not only provides a methodology for the software development process, but also combines best practices and processes together with the Unified Modeling Language?s notations and diagrams for better understanding Object-Oriented Concepts and system development, in the context of effective management of information.
Design and Implementation of a Web-Based Faculty Information System

Although Information Systems (IS) are valuable elements for organizations, the private and public sectors in Sri Lanka are reluctant to use IS for decision making, organizing and classifying data, processing transactions, and for many other activities. This is caused by the lack of computer literacy and conventional attitudes of the majority of the Sri Lankan community. Even in the higher education institutions in Sri Lanka, majority of both staff and students who are well aware of information technology, rely on conventional ways of handling information. One major reason for the above issue is lack of availability of application software well suited for their needs. On one hand, such types of software are rarely used by institutes because of their high cost; on the other hand, they are highly organization dependent. Hence steps have been taken to build a Faculty Information System (FIS) for the Faculty of Science, University of Kelaniya. The FIS was developed in a network environment, with the active participation of all those involved by means of continuous dialogues with the aim of both promoting and demonstrating its benefits and by catering to the different needs arising from the faculty community. The FIS consists of three major subsystems, namely FIS Web Based Subsystem (FISW), FIS Intranet Sub System (FISI) and FIS Examination Sub System (FISE). FISW provides www access to FIS users at any time from anywhere. FISI enables the capability of access to FIS via the Faculty office local area network with security restrictions. FISE processes the examination data in a highly secured environment which is separated from both FISW and FISI. FISI and FISW eventually connect with FISE under security restrictions as required. It is clear that development of this type of tool has social, cultural and technological dimensions. What we planned is one thing, what happened in reality and how the stake holders respond to the tool is another. An evidence of the neediness of this type of tool to the faculty is the number of accesses, 41784, in two years. The above figure is not a complete measure of acceptance of FIS. To detect its defects and limitations, in addition it is necessary to take into account the number of pages requested by each registered user in the FIS. These statistics can be used to enhance the features of FIS.
E-enabling the Sri Lankan Agriculture Industry
(University of Kelaniya, 2005) Udugampola, R.T.; de Silva, C.H.
This paper presents the design and implementation of an e-trading system for vegetables and fruits farmers in Sri Lanka to maximize the product distribution and yields gain by directly liaising with the buyers for the sale of their products at completive prices. The system under discussion is about enabling the local farmers to use mobile and internet technologies to trade in their products in place of the conventional buyer -seller interactions. The proposed system is based on a typical commodities trading system where the farmer advertises his products and the buyer then directly negotiates with the farmer concerned and the related transactional activities which would take place from this point onwards. The paper discusses in detail how a system of this nature could be implemented in the local context, its benefits and the suitable technical infrastructure which is needed for its successful implementation. The paper extensively discusses newer and emerging mobile internet technologies that could be effectively deployed in a developing country for benefit of the local farming community and in general the infrastructural developments which would take place as a result of successful implementation of the system described in the paper. The e-trading system typically revolves around a client-server architecture. The web based interface is primarily targeted towards the trader. However, a Sinhala native language web interface too has been designed for the farmer, so that he would have an auxiliary interface to the system if the mobile application interface was found to be too difficult to use. With the present e-Sri Lanka initiative and the propagation of ICT know-how in rural areas of Sri Lanka, the authors envisage a highly mature robust system could be evolved from the proposed system in order to cater to the local situation which, in turn would open up employment opportunities as well.

Integrating ICT in foreign language teaching: A Sri Lankan experience
(University of Kelaniya, 2005) Premawardhena, N.S.; de Silva, C.H.
Foreign language learning has become increasingly popular in Sri Lanka during the past few decades. This study discusses the significant contribution ICT could make to foreign language teaching in Sri Lanka. Native speakers are born with the competence to grasp the language(s) spoken and used in the environment they grow up. However complicated the phonetic, phonological, syntactic or semantic structure of the particular language(s) may appear to an outsider, the native speaker acquires it with such ease and competence, which makes human language ability a unique phenomenon. The foreign language learner has to acquire this language competency with much effort. Thus it is the task of the foreign language teacher to impart the language knowledge effectively to minimise the difficulties faced by the learner. Furthermore, an integral part of learning a foreign language is, understanding the culture and lifestyle of the particular speech community. The limited number of hours devoted to class room teaching is not sufficient to acquire a language or impart knowledge required to master the finer points, mainly the cultural and sociolinguistic aspects of a language. The use of idioms, figures of speech, proverbs, and sociolinguistic variables, for instance, demand a deeper knowledge of understanding than learning the basic rules of grammar and vocabulary of a language. This paper discusses how the integration of ICT could improve language teaching and pave way for more effective skills in foreign language acquisition. Thus the aim of the study is to find the effectiveness of technology enhanced foreign language teaching comprising language learning software, speech synthesis, web-based technology, virtual platforms for seminars and exchange of information and multimedia content. The study focuses mainly on data available from two pilot projects conducted at University of Kelaniya in integrating ICT in foreign language teaching at elementary, intermediate and advanced levels. However, it is expected that the results obtained will benefit foreign language teaching in Sri Lanka at large and reach a wider audience to encourage the use of ICT in language teaching more effectively in the future.
