Android has become most popular and powerful embedded operating system. Nowadays, it is used in other electronic items other than mobile phones like TV, Camera, etc. The purpose of this study is to find out the difference in performance between the different methods for developing applications due to an increasing market for platform independent applications. In this research work, we present our current findings concerning performance efficiency in cross-platform and native mobile applications (apps) and how they can contribute to a general benchmarking approach. At first, several test cases for evaluating performance of mobile applications are described with which two applications where built to implement a mathematical calculation for both native and hybrid respectively. This is used as benchmark because of the recursive nature and memory usage of both applications for CPU and memory usage. Then, the performance efficiency of native and hybrid apps is compared on a mobile device. The results show that hybrid applications still suffer performance issues in comparison to native apps. The performance deviations and reasons for them are discussed and evaluated. It is concluded that the performance of mobile applications is crucial to user experience and satisfaction.

Cloud computing is growing significantly day by day, and has created a shift in the IT industry. It brings several advantages of having the potential to bolster economic growth through the provision of cost savings and efficiencies by delivering computing as a service, such as self-service, on-demand, broad network access, rapid elasticity, resource pooling, and measured service. Today, individuals and organizations are fast embracing and adopting cloud computing to take advantages that the technology brings. While the growth of the cloud technology is growing exponentially in the North American, European and Far Asian countries, the case of the Africa seem to be difference as the growth rate is at the lowest level. This paper presents the trends and the challenges of advancing the cloud technology and services in Africa with some recommendations on how these challenges can be solved.

Pigeonhole is an internal information exchange system, used for communication in an organization. It is a creative, informal and traditional way of dropping and picking messages in a set of small open-fronted compartments usually used in a workplace or other organizations where letters or messages may be left for individuals. The chain of exchange is a kind of 'give-and-return'. It is a bi-directional 'pick-and-respond' information transmission mode. Internal and informal investigations carried out in most departments in Adekunle Ajasin University, Akungba-Akoko (AAUA), Ondo State, Nigeria, however show that the purpose of this dual-mode communication is most times defeated as recipients of pigeonhole-kept information are remote and unaware of any 'visitor' awaiting them. The researchers therefore deem it fit to close up this gap and ensure maximal consumption of the benefits pigeonhole system offers. We are therefore poised through this study, to design and implement a mobile-based, interactive and informative pigeonhole alert system that captures information meant to be archived in a pigeonhole, disseminate the information and monitor the receipt or otherwise of same with appropriate feedbacks. The proposed system allowed for easy and enhanced communication between the administrator incharge of messages (e.g. the office clerk) and the recipients, to ensure proper dissemination of information. The design and implementation were accomplished using Java and XML components of Android Software Development Kit (SDK).

This paper reported the influence of health records management practice on disease surveillance and notification system in Atakumosa West Local Government Area of Osun State. The study aimed at combining insights of how health records management practice bridges different aspects of disease surveillance and notification system in Atakumosa West Local Government Area of osun State. The study adopted survey research design to establish relationship between health records management practice and disease surveillance and notification system in Atakumosa West Local Government Area of Osun State. Structured questionnaire was used to elicit data on the variables under investigation and a total of 115 out of 120 respondents completed the questionnaire with a total of 96% response rate. Simple percentage distribution was used to analyze and answer the research questions posed in this study. The inferences drawn from existing literatures, postulated theories and data collected from the field indicated that correlation exists between health records management practice and disease surveillance and notification System, as evident in previous research works, case studies and analyzed data. The study recommended the need for the management of Atakumosa West Local government to procure and install appropriate information technology to sustain health records management practice and disease surveillance and notification system. Also, capacity building, adequate funding, provision of logistics and working materials that will guarantee timely collection, processing, and availability of healthinformation are very imperative to a result-oriented health
