This paper discusses on a novel method for semantic searching and retrieval of information about learning materials. A novel metametadata taxonomy has been developed which provides the basis for a semantic search engine to extract, match and map queries to retrieve relevant results. Metametadata encapsulate metadata instances by using the properties and attributes provided by ontologies rather than describing learning objects. The use of ontological views assists the pedagogical content of metadata extracted from learning objects by using the control vocabularies as identified from the metametadata taxonomy. The use of ontological approach and metametadata (based on the metametadata taxonomy) have contributed towards a novel semantic searching mechanism. These three strands - the taxonomy, the ontological views, and the search algorithm - are integrated into an architecture (OMESCOD) to support the semantic search within the metadata repository.

Presently, mobile handheld device has successfully replaced traditional telephone to become the most popular wireless communication tools. Mobile Short Message Service (SMS) and Multimedia Message Service (MMS) fulfill almost all the user requirements as an effective communication and information delivering service. Since SMS/MMS become so popular on daily communication, there is a demand to communicate or exchange confidential information in a secure environment. Public Key Infrastructure (PKI) is a proven solution, which using pairing of key, for secure communication encryption. In this paper, m-PKI is introduced to provide PKI encryption to the mobile SMS and MMS. This new approach allows the end-user to send private and classified message via SMS. The key pair generation and distribution are performed by the Certificate Authority (CA). The size of the key pair are studied and decided by the tradeoff between performance and security.

In this paper, we consider sorting problem with n elements distributed over a number of processing entities in a distributed system. We have derived an alternative, efficient algorithm with the worst case lower bound of (n - 1) rounds for distributed sorting on a line network, where n is the number of processors. The proposed distributed sorting algorithm improves the performance of each processor without creating copies of (n - 2) elements at intermediate processors and reduces the execution time of Sasaki's time-optimal algorithm [A. Sasaki, A time-optimal distributed sorting algorithm on a line network, Inform. Process. Lett., 83 (2002) pp. 21-26]. Also all processors do not necessarily perform the disjoint comparison-exchange operations and simulation results show that the proposed algorithm results in better execution time with the identity of processors. This algorithm could also be extended for sorting the distributed elements on the linear embedding obtained from a general network.
