Background: A comprehensive medical care system is required for effective healthcare delivery to people who need it. Even though exact configuration of healthcare services varies from country to country, a sturdy mechanism comprising of a robust financing, a well-trained and adequately paid workforce; research, policy recommendation and implementation is needed for a well-maintained system to deliver effective healthcare services.

Methods: This is a descriptive study conducted on 100 Nigerian trained physicians with at least 1-year practice experience. The online questionnaire was administered to participants through social media platforms such as WhatsApp, Facebook and twitter using purposive sampling method. Data analysis was done using Microsoft excel 2010 version.

Results: The response rate was 100%. Ninety six percent (96%) and 99% of surveyed physicians think their monthly salary and the amount of money budgeted to the health sector is grossly inadequate. It was also noted that poor enumeration and/or low income 82/330 (25%) and poor medical facilities 70/330 (21%) are the commonest reasons they believe physicians  emigrate from Nigeria while problem identification (20.2%), provision of leadership, healthcare service delivery (13.5%), policy making and implementation (12.9%) and research and development (10.4%) are the commonest roles for physicians identified by study participants.

Conclusion: The Nigerian physician is poorly enumerated, and the healthcare budget is poor. This accounts to large part why leave Nigeria.  There is need for better funding of the healthcare system in Nigeria and more involvement of physicians in leadership, research and policy development.

Measuring the complexity of software has been an insoluble problem in software engineering. Complexity measures can be used to predict critical information about testability of software system from automatic analysis of the source code. In this paper, Improved Cognitive Complexity Metric (ICCM) is applied on C programming language. Since C is a procedural language, the cognitive complexity metric is capable to evaluate any procedural language. This paper presents a cognitive complexity metric named ICCM. First, the metric is analytically evaluated using Weyuker’s properties for analyzing its nature. Secondly, perform a comparative study of the metric with the existing metric such as NCCOP, CFS, CICM and CPCM, and the result shows that ICCM does better than other metrics by giving more information contained in the software and reflecting the understandability of a source code. Also, an attempts has also been made to present the relationship among ICCM, NCCOP, CICM, CFS and CPCM using pearson correlation coefficient method.

This paper evaluates voice quality of four Global System for Mobile (GSM) Communication providers in five selected cities in Kwara State with thoughtfulness of network performance evaluation and the quality of service (QoS) improvement of GSM network system. Three assessment components/parameters which are network accessibility, service retainability and connection quality for evaluating QoS on the network were mainly adopted. The parameters were applied on four GSM networks in the studied areas using customers’ complaints method. Also, a standard method known as Perceptual Evaluation of Speech Quality (PESQ) — (International Telecommunication Union-Telecommunication Standardization Sector) ITU-T standard P.862, used for measuring call voice quality and Mean Opinion Score (MOS) is adopted. The two methods were therefore compared to assess call voice quality of the four GSM networks. The Key Performance Indicators (KPIs) on which the GSM networks were tested include call set-up success rates (CSSR), call drop rate (CDR), call completion success rates (CCSR), handover success rates (HSR) and traffic channel congestion rate (TCHR). The result of the study shows that the Quality of Service of GSM system in the selected cities is unreliable. The study also shows that the GSM network accessibility and retainability in the country are unsatisfactory. However, the call voice quality was observed to be on the peak in these cities across the four network providers. At the end of this manuscript, suggestions are given on how to advance both the Quality of Service and the positive impact of GSM network in the selected areas and the country as a whole.

We present a body of results that demonstrate that the golden section can be implemented in the design of evolving systems. Albeit we only develop the mathematics, both mathematician and computer expert should find the concept clear. Perhaps of particular interest to the number theorist is the observation that the sequence  defined by  known as the Teleois number system, crops up in our results. Having shown in previous works how this sequence is closely related to the golden section, this manuscript gives further confirmation and the fact that Teleois numbers penetrate the golden section renders it a proportion of great splendour. Our results can find a wide range of applications from information technology to manufacturing.

Analysis of Congestion of Mobile Network in Offa

The study of congestion of mobile network in Offa is necessary as congestion remains a major challenge to telecommunication service provision both to service providers and the subscribers as well, even in developed country. Offa is a renowned city in Kwara State, Nigeria. Cellular wireless systems such as GSM suffer from congestion resulting in overall system degradation and poor service delivery. Obviously, subscribers are susceptible to quite network providers who fail to meet up with the services required of them. In this research, areas on the GSM network where congestion occurred were analyzed including the various causes of congestion on GSM network. This research work also brought to bear recommendation that necessitate the need for service providers to create a mutual benefit between the service providers and subscribers.

The tool used for data collection was a Five Point Likert attitude scale questionnaire. The Data collected for this study were analyzed using frequency counts, simple percentage (%) and mean score (x).
