E-Health cloud for Nigerian Teaching Hospitals

major challenge to the adaptation of e-Health solution in developing countries is the lack of infrastructure for massive data storage and availability of resources on demand. With well over 150 million people to care for, the health sector in Nigeria lacks an organized and interoperable data storage facility to hold large volumes of data that results from unprecedented visits of patients to hospitals on a daily basis. This has further worsened the ineffective and cumbersomeness of treatment processes due to inconsistence in data representations. This paper tends to address this issue by proposing a Cloud computing infrastructure for e-Health solutions in Nigeria. This will help to effectively and efficiently manage healthcare resources and data and also make healthcare services available across the existing teaching hospitals in the country

Design and development of a tertiary institutions decision support system (TIDSS)

In Nigeria and some other developing countries, the conventional process of choosing a university to attend and the courses to study are usually stressful, ineffective on prospective students. Some applicants go through a whole year thinking and trying to find the right course to march their areas of interest, and the right university to attend in order to obtain the very best education. Some end up choosing the wrong course of study and subsequently, the wrong university. This affects the academic performance and future of such students and the nation at large. This paper presents the design and development of a Tertiary Institutions Decision Support System (TIDSS) to solve the major problem of "university/course choice confusion". The TIDSS offers decision support, consultancy, repositories, current helpful information, effective search engine, virtual tours of universities (where available) and independent platform for various users in any part of the world, thus, eliminating/reducing the cost and risk of travels in search of schools to attend. The system was modeled with the Unified Modeling Language (UML), which is the globally accepted standard for modeling object-oriented systems. In addition, Hypertext Pre-processor (PHP) server-side language, which is an open source server-side scripting language that is freely available for download was used to implement the system. MySQL database server was used to manage all the data in the application. The Joint Admissions and Matriculation Board (JAMB) Brochure was used extensively in order to give current information about the courses and universities available in Nigeria.Keyword: Tertiary institutions, Decision Support System, Unified Modeling Language, NigeriaInternational Journal of Natural and Applied Sciences, 6(2): 206-212, 201

Towards Developing an Online Social Media-based Mobile Learning System

ABSTRACT The advancement of Information and Communication Technology (ICT) and the Internet revolution gave rise to the several learning technologies on the web and mobile platform. During the last decade, the social media network became available for users to socialise and collaborate among peer group. Hence, The integration of e-learning and social media using mobile device as access point is to allow for learning and collaboration anytime, anywhere. This study seeks to provide learning on the social network platform for users to view the application on a mobile device and also foster collaboration among scholars. The system was developed using an open source Content Management System (CMS) Wordpress and Buddypress running on a WAMP or XAMPP server. MySQL was used as database. The usability of the System on the different mobile devices used was evaluated by identifying the usability attributes; designing a questionnaire based on those attributes and then analyzing the results with Statistical Package for Social Science (SPSS). The results showed that the learning system had a good usability score on mobile devices.

Developing Medical Devices from Abstract State Machines to Embedded Systems: A Smart Pill Box Case Study

The development of medical devices is a safety-critical process, because a failure or a malfunction of the device can cause serious injuries to the patients whom use it. The application of a rigorous process for their development reduces the risk of failures since validation and verification activities can be performed in a objective, reproducible, and documentable manner. In this paper we present an approach based on the Abstract State Machine (ASM) formal method. Starting from the model, validation and verification (V&V) techniques can be applied. Furthermore, by step-wise refinement, a final model can be obtained, which can be automatically translated to code. The process is applied to the smart pill box case study. Starting from the ASM model, we generate code for the Arduino platform after the application of V&V activities. Furthermore, we introduce regulation (IEC62304) and guidelines (FDA General Principles of Software Validation) that support the developer in medical software development. In particular, we explain how ASMs formal process can be compliant with them
