Fault Tolerance in Intranet Information Systems for Tertiary Health Institutions

The critical nature of information and data in some systems like health sector requires a system that gives optimal tolerance to fault without trading off or compromising system integrity, availability and security in order for the system to afford greater efficiency. The main thrust of this work is to examine health system information flow and application(s) in the light of fault tolerance and come up with application software of higher tolerance to fault that can be deployed as an intranet in a tertiary health institution for sharing Patients’ Case Notes among care givers. Besides extensive literature review on the work, Ladoke Akintola University of Technology Teaching Hospital, one of the teaching hospitals in Nigeria, was chosen as a case study. The various departments and users are interviewed and interacted with in order to, among other things, gather system requirements. The software development technologies used are ASP.NET with Visual Basic as language and Microsoft SQL 2005 Express Edition. The platform used is Visual Web Developer 2008 Express Edition. The web server used is Internet Information System (IIS). Keywords: fault tolerance, information system, health institution, health care, case note

A C T 91 Intraoral penetrating injury from a long metallic foreign body: a case report

Children often play with sharp objects in their mouths without knowing the injurious effects of such action. These objects can accidentally cause severe injury to oro-pharyngeal tissues. Timely removal of such objects is essential to prevent life threatening complications. This paper presents a case of an intraoral penetrating injury in a 5 year old patient caused by a long metallic foreign object. The foreign body was successfully removed by meticulous exploration through the existing wound. Educational measures such as enlightening the parents and guardians on the importance of keeping dangerous materials from the reach of their children may be necessary. The need to immediately bring such patients to the hospital for expert management in case of inadvertent injury and also to comply with follow-up appointments is also essential

Properties of Plastic Bounded Agricultural Waste Composites II: Physical Properties of Some Composites

Twenty six (26) plastic bounded composites, one unfilled and five each filled separately with varying contents of cement, limestone, silica-sand, drainage san granite have been formulated and compounded. Their percentage water absorption was determined. Composites % water absorption was determined. Composites % shrinkage range from (0.86-8.00) % and % water absorption from (1.03-15.00) %. These results suggest that the composites under study meet the allowable American Standard for Test Measurement (ASTM) for floor and wall tile tiles maximum 15% shrinkage and maximum 16% water absorption. If these composites are examined for mechanical strength, they may be found useful in the building industry for the manufacture of floor and wall tiles. Using spent pure water (thermoplastic) may result in the control of environmental pollution caused by the non-biodegradable spent plastic. Key word: plastic bonded composite, floor tile, wall tile, % shrinkage, % water absorption allowable ASTM

A Table Mounted Device for Cracking Dika Nut (Irvingia gabonensis)

A simply designed machine for cracking dika nut was fabricated. The nut is fed by hand inbetween a toggle mechanism comprising of the slider and a fixed block. Fracture mechanism was based on the deformation characteristics of dried dika nut under uni-axial compression. When actuated, the slider compresses the nutshell to failure along its line of symmetry. The experimental machine gave 100% cracking efficiency but with 24% kernel breakage in cracking sun-dried dika nut at 6.6% moisture content (w.b). The machine provides a viable and effective technique for safe dika kernel extraction

The influence of steel die parameter and micro-structural investigation on AA6063 aluminum alloy

The study investigated the influence of steel die parameter and the microstructural evaluation of AA 6063 aluminum alloy extruded at room temperature using different die entry angles. Mild and tool steel dies of entry angles of 15o, 30o, 45o, 60o, 75o and 90o were used to extrude the work sample. Microstructural analysis, coupled with ram velocity, elongation, hardness, and maximum extrusion pressure of the extruded samples, were de-termined. It was observed that theaximum extrusion pressure required for extrusion and hardness of extruded samples increased with increasing die entry angle .Experimental results show that aluminum alloy deforms better when the die material is made of mild steel with die entry angles of 45o, 75o and 90o as compared to tool stee

Development of a Proactive Fault Diagnosis for Critical System

Large-scale network environments, such as the Internet, are characterized by the presence of various devices connected at various remote locations. There is a scenario of main office connected to different branch offices in another town and cities, with the presence of central administrative system at the main office. Any problem at branches is reported to the main office, due to availability of enough resources there. However, few support tools have been developed to allow the administrators at the central office to remotely control and monitor the computers at the branches. Even, in local area network environment, diagnosing the computers on the network is always a big problem for the administrator, as he/she moves from one computer to another, running the diagnostic program and collecting report for each machine tested. This is strenuous and time consuming. To help address these problems, I have employed the concept of mobile agent to design an architecture that can remotely perform various checks and tests on computers on network, and report its findings to the server administrator as central location. This architecture was implemented with Java, using Jini lookup service to establish communication between the computers. The agent tasks were implemented in C programming language. The result of this research work shows that the use of mobile agent for remote maintenance of computers on network was found to provide an improved, efficient, and dynamic diagnostic management system. All the same, it has proven to be a substantive contributor to efficient network management

Comparison of Perceptual Reasoning Skills and Mental Health Problems between Deaf and Normal-Hearing Adolescents in a Semi-inclusive setting in Ibadan, Nigeria

Background: Adolescents with hearing loss are often faced with poor cognitive and executive functions, and increased prevalence of mental health problems. The study compared the perceptual reasoning skills (PRI) and mental health problems of deaf adolescents with those of their age- and sex- matched hearing counterparts.Methods: It was a comparative cross-sectional study of a total population (102) of deaf adolescents, who were matched for age and sex with 102 normal hearing adolescents. The PRI of the participants was assessed using the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV). Mental health problems were assessed with the parents’ and teachers’ versions of the Strengths and Difficulties Questionnaire (SDQ). Descriptive statistics, chi square test and correlation co-efficient were done. Significant level was set at p-value < 5%.Results: The PRI scores ranged from 41-106 across both groups; 58.8 % of the deaf and 41.2% of the hearing adolescents scored 69 and below on the WISC and this difference was statistically significant (p = 0.033). The PRI scores had no significant relationship with the audiometric scores of the deaf participants (r = -0.177; p = 0.076). The PRI scores in the deaf participants were inversely related to hyperactivity assessed by the teacher (r = -0.354), emotional difficulty assessed by both teachers (r = -0.221) and parents (r = -0.280) and peer problems assessed by the teachers (r = -0.329).Conclusion: Deaf participants in this study showed significantly lower level of nonverbal IQ and higher level of behavioural difficulties compared with their hearing counterparts

Impact of Abandoned Structures on Residents in Ilorin, Kwara State, Nigeria

The increasing incidence of abandoned structures coupled with the associated seemly insurmountable environmental, psychosocial and economic risks in a developing country like Nigeria is a nerve racking problem of concern to the government and the communities. The study therefore, within the context of the three residential densities the study examined the incidence, causes and impacts of abandoned structures with a view to providing information on the extents and effects of abandoned structures on residents in Ilorin. The study utilized primary data obtained with the aid of questionnaire from 428 residents collected in the ratio 3:2:1 in high, medium and low density residential areas. Four indices were developed: ‘Environmental Impact of Abandonment’ (EIAI), ‘Psycho-Social Impact of Abandoned Structures’ (PSIASI), ‘Economic Impact of Abandonment’ (EcIAI) and ‘Suggested Solutions to Abandonment’ (SSA). It is observed that the incidence of abandoned structures varies significantly among the residential neighbourhoods of Ilorin metropolis (F = 9.458 and p = 0.036 at 95% confidence level). The magnitude of the six categories of abandonment in Ilorin metropolis is more in the high density area then in medium and low density. Residents of different residential densities of Ilorin do not have the same or similar views about the environmental effect of abandonment in their areas (F= 4.604 and p= 0.0160. The study recommends as suggested by respondents increase in basic salary (SSA =, 4.31) local planning authority should work on blight control (SSA = 4.29) and there should be proper site selection before commencement of building projects (SSA =.4.28).
