Title: Clinical Decision Support System: Risk Level Prediction Of Heart Disease Using Decision Tree Fuzzy Rules

Paper ID: ATC-60203031
Pages: 1 - 11
Abstract: As people have interests in their health recently, development of medical domain application has been one of the most active research areas. One example of medical domain application is detection system for heart disease based on computer-aided diagnosis methods, were the data are obtained from some other sources and are evaluated based on computer based applications. At the earlier time, the use of computer is to build knowledge based clinical decision support system which uses knowledge from medical experts and transfers this knowledge into computer algorithms manually. This process is time consuming and really depends on medical expert's opinion which may be subjective. To handle this problem, machine learning techniques have been developed to gain knowledge automatically from examples or raw data. Here, a weighted fuzzy rule-based clinical decision support system (CDSS) is presented for the diagnosis of heart disease, automatically obtaining the knowledge from the patient's clinical data. The proposed clinical decision support system for risk prediction of heart patients consists of two phases, (1) automated approach for generation of weighted fuzzy rules, and (2) developing a fuzzy rule-based decision support system. In the first phase, we have used the mining technique, attribute selection and attribute weightage method to obtain the weighted fuzzy rules. Then, the fuzzy system is constructed in accordance with the weighted fuzzy rules and chosen attributes. Finally, the experimentation is carried out on the proposed system using the datasets obtained from the UCI repository and the performance of the system is compared with the neural network-based system utilizing accuracy, sensitivity and specificity.

Title: Impediments Facing the Introduction of Cloud Computing Among Organizations in Developing Countries: Finding the Answer
Author(s): Arthur Ume, Adolphus Bassey, Hassana Ibrahim
Paper ID: ATC-70209042
Pages: 12 - 20
Abstract: Cloud computing is a rapidly evolving innovation that offers the potential for businesses to gain competitive edge globally. With the advent of Cloud computing, organizations may easily port and render their businesses, services and operations across the globe via the Internet. This huge possibility looks very attractive, and increasingly many enterprises in the developed economies are beginning to think of how to leverage this opportunity; with Cloud computing, services and data may be provided by shared computing resources in scalable data centers and made accessible over the Internet. Nevertheless, there is still a predominant and nagging fear (phobia) surrounding the adoption of the easy-to-manage offerings of the Cloud computing technology, especially in developing countries like Nigeria. This paper gives a general insight into Cloud computing and its history. It then attempts to investigate why businesses tend to shy away from the use of the services which can/may be rendered in the Cloud. It further discusses the prospects of extensively introducing and leveraging Cloud computing as a means of rendering distributed business operations and services in a cost effective way especially in developing sectors of developing economies like Nigeria where organizations and companies may not be all that economically buoyant to own and build their own individual "silo technologies" to attend and solve crucial business needs. Finally the paper suggests how to start overcoming the in-built and inherent resistive attitudes towards Cloud computing.

Title: Underscoring Software Engineering Ethics in Nigeria's fast Growing Information and Communications Technology.
Author(s): Arthur Ume, Jane Chukwurah
Paper ID: ATC-40210043
Pages: 21 - 30
Abstract: For more than a decade now, Nigeria has been witnessing a continuous improvement and boom in the application of Information and Communications Technology in all the vital sectors of her economy. There is an increasing dependency on computer programs for critical infrastructures, business processes and operations. This boom is not abating, and is resulting in a corresponding increase in the number of companies and individuals who join an increasing population of software engineers, enterprise application developers and programmers. But regrettably, the boom has given rise to a host of ethical issues. The ability to make sound ethical judgement and decision is becoming very important as "half-baked" software developers produce critical software that are supposed to run critical business functions and operations. To compound this problem the few technical schools or colleges that produce the very needed programmers and web designers do not have a clue that there is something negative creeping in from another angle; they do not have qualified or versed instructors to arm their graduates with the basic foundation knowledge in software professional ethics which is needed to effectively practise the art of software engineering in the society at large. This paper investigates the state of software engineering ethics in the face of Nigeria's upwelling Information and Communications Technology and intention to produce and use locally designed and implemented software. The paper calls attention to the nonchalance, dispassion and mass negligence attendant to this issue. It further highlights and calls for adherence to sound ethics at all levels of software production in the Nigerian society at large. The paper uses a case-study and scenario to illustrate how to start doing so.
