A Profile of Unemployed Malay Graduates. Munir Shuib, Mohd Zainul Fithri Othman, Mohd Shukri Ab. Yajid. (vol.3 no.1, 2005) p.1

Abstract
Many reports, including newspaper articles, show a clear concern about the weaknesses of Malay candidates in employability compared to other ethnic groups especially the Chinese. They have been described as “uncompetitive”, “lazy”, “choosy”, etc. Most of these comments, however, are impressionistic, based largely on personal observations, hunches, presuppositions, and limited experience. The aim of this paper is to explore several characteristics of unemployed Malay graduates in Malaysia based on a number of existing related studies. Such exploration is vital because Malays constitute the majority of unemployed graduates in the country. An understanding of their traits may reveal possible causes of their unemployment and suggest remedial measures.

Short-Term Toxicity Study of Andrographolide Oral Suspension in Mice. K. Senthil Kumaran, Asbi B.A., Junainah A.H, P. Thiruganasambantham, S. Viswanatan. (vol.3 no.1, 2005) p.8

Abstract
Short-term toxicity of andrographolide oral suspension was carried out in swiss albino mice. Twenty-four male and female mice were divided into four groups of six animals each and were administered andrographolide oral suspension in doses of 50, 100, 500mg/ kg daily for 28 days. Control group received vehicle. Cage-side observations for changes in morphology, behavior and body weights were monitored at weekly intervals. At the end of exposure period, hematological, biochemical and pathological changes were examined. The results revealed that andrographolide oral suspension even at high dose level (500 mg/kg body weight) did not produce any significant alteration in the hematological and bio-chemical parameters in mice. No mortality was observed. The andrographolide oral suspension is devoid of toxic effects in mice upto a dose of 500 mg/kg.

Confronting Inequities in Health Service Delivery: An Overview of the State of the South African Health System. Yoswa M. Dambisya. (vol.3 no.1, 2005) p.13

Abstract
South Africa is faced with the problem of redressing the imbalances of its racial apartheid past. Among these is the delivery of social services for the majority of the population that had been denied access as a matter of policy. In the apartheid era, the health sector was fragmented and largely biased towards private, curative and specialist services, and did not cater for the majority of the population. Since 1994, government has undertaken a number of measures towards equity in health service delivery, and has made a lot of progress in a many areas. Nevertheless, a lot remains to be done. This paper highlights the current state of the South African Health System, with a focus on the major achievements over the last eleven years and outstanding challenges.

Assessment of Regenerative Periodontal Therapy by Texture Analysis of X-Ray Digital Images. Md. Gapar Md. Johar, V. Ramaswamy, K.S Hareesha, Mallikarjuna S. Holi. (vol.3 no.1, 2005) p.24

Abstract
The objective of the present work is to employ X-ray images and manual measurements for the assessment of surgical re-entry in regenerative therapy of periodontal intra-bony defect. The focus of this study is on analyzing the texture features of the digital images of post surgical growth of the bone fill between two teeth. Pre-treatment radiographs were taken and stored. Bone fill radiographs and clinical measurements were taken nine months after surgical re-entry. All radiographs were digitally scanned at 600 dpi and analyzed after equalizing the images on a computer. The analysis was carried out on pre-treatment and post-treatment digital images of the region of interest (ROI), i.e., the space between the two defective teeth. The statistical significance for both pre- and post-treatment analyses of paired data sets of patients in the age group of 35 to 50 years was calculated. The student‘t’ test was carried out on the data sets on the statistical parameters. The result shows a significant difference (p < 0.005) between the pre-treatment and post-treatment images, indicating a growth between the two teeth.

Data Discovery Mechanism for a Large Peer-To-Peer Scientific Data Grid. Azizol Abdullah, Mohamed Othman, Md. Nasir Sulaiman, Hamidah Ibrahim, Abu Talib Othman. (vol.3 no.1, 2005) p.30

Abstract
A Data Grid typically deals with large computational problems and provides geographically distributed resources for large-scale applications that depend on large data sets. In modern scientific computing communities, scientists deal with massive amounts of data stored in geographically dispersed data centers. Research into grid computing has given us several ideas about how to address these issues. Currently, a number of researchers are working on data distribution problems in grids. They are investigating a number of replication approaches to data distribution. This leads to a new problem in discovering and accessing data in the grid environment. Peer-to-peer networks also have become a major research topic over the last few years. A distributed peer-to-peer system too requires a discovery mechanism to locate specific information, applications and users of the system. In this paper, we present a large peer-to-peer distributed system as a model of a scientific data grid. The use of this model allows us to extend the discovery mechanisms used in peer-to-peer architecture to the solution of problems in dynamic scientific data grid environments. We propose and illustrate a Grid Simulator based on this model. We then analyze the performance of the discovery mechanisms in relation to their success rates and bandwidth consumption.

Using a Multiple-Arc Network Model for Planning Production in a Multi-stage, Multi-Item Process. Bokkasam Sasidhar. (vol.3 no.1, 2005) p.40

Abstract
The planning of production in a multi-stage, multi-item compatible environment aimed at optimal capacity utilization is formulated as a maximal flow problem in a Multiple Arc Network (MAN) with ‘gains’. The production is usually planned against orders, and according to varying priorities assigned to different customers. The model proposed here provides optimal production schedules at all stages so that full capacity is always utilized, and customer-specific delivery schedules are met. The paper formulates algorithms for (a) solving MAN with gains formulation of production planning accommodating customer priorities, and (b) determining stage-wise requirements of time and materials for the commencement and continuation of the production process.
Keywords: Production Planning, Maximal Flow Problem, Multiple Arc Network Model, Optimization.

Business Process Reengineering: More Than a Management Fad. Tang Meng Keang. (vol.3 no.1, 2005) p.47

Abstract
It is usual for managers to introduce management concepts as part of their efforts to improve organizational effectiveness. Some managers look upon these concepts as the savior of their problem-ridden organizations suggesting, for example, new marketing strategies in a fiercely competitive environment. Some others use them for their personal survival in the profession, by using them, say, to project an image of themselves as professionals in tune with the latest developments in management research. The strategies sometimes misfire: a marketing plan based on a radically new concept goes completely haywire, or the euphoria surrounding a revolutionary research idea dissipates instantaneously after its implementation in a practical situation. We apply the term “fads” to such concepts, i.e., to concepts that prove to be nothing more than passing fancies of a few over-zealous seekers of novelty for its own sake. In this paper, we intend to examine the fortunes of one management concept, viz., Business Process Re-Engineering (BPR) with a view to determining whether it qualifies as an enduring management tool or as a management fad, i.e., whether it stood the test of time or was an idea that had its brief hour of glory, but then faded into oblivion. We also intend to explore its critical success factors on the basis of case studies and literature survey. Three cases are discussed, namely The Inland Revenue Authority of Singapore (IRAS), American National Bank of Florida (ANBF), and Blue Shield of California (BSC). All of them had been going through crisis situations, and all three opted for BPR as a way out of the crises. We identify the support and co-operation shown by the members of the organization, large-scale adoption of Information Technology tools, and team-based organizational structure as the crucial success factors of the BPR exercise undertaken by these companies. The role of these three success factors is further strengthened by what we find in the recent research literature dealing with BPR. There are likely to be other factors that have proved to be critical for the success of BPR in other contexts, but we reserve them for examination at a later time.

Effective Materials Production in E-Learning. Robin Mason. (vol.3 no.1, 2005) p.57

Abstract
It is well known that developing quality e-learning materials can be a very expensive and time consuming business. However, there are ways of being effective in online teaching without spending vast amounts of time or money. Although the UK Open University does develop some of its e-learning material in this resource-intensive way, this is reserved for large courses where re-use can be guaranteed by many students over many years. For smaller courses we use different means of materials production, and these can be equally effective.
