    In this paper, we explore the security and privacy issues of Internet of Things (IoT) healthcare applications for special needs users. IoT enables health-related organizations to lift important data from diverse sources in real-time and this helps in precise decision-making. The transformation of the health sector, required enhancement and efficiency of protective systems, thereby reducing data vulnerability and hence, providing opportunities for secure patient data, particularly, for special needs patients. A quantitative method for purposive sampling technique was adopted and eighty-eight respondents provided the process of how the IoT technology was utilised. Data findings indicated that IoT monitoring devices have the detective ability for a person with special needs living alone with problems related to vital signs of diseases or disabilities. Personal patient health records are integrated into the e-health Centre via IoT technologies. For data privacy, security, and confidentiality, patients' records are kept on Personal Health Record Systems (PHRS). The research revealed suspected breaches of information due to cyber-attacks on the probability of false data errors in the PHRS, leading to special needs personal data leakage

    The broad range of activities contained in the provision of Primary Health Care (PHC) places a burden on providers to make optimal use of limited resources to achieve maximal health benefit to the population served. All too often, ad hoc decisions and personal preferences guide PHC resource allocations, making accountability for results impossible. Problems constraining Routine Health Information System (RHIS) performance in low-income countries include: poor data quality; limited use of available information; weaknesses in how data are analyzed and poor RHIS management practices. This study sought to investigate these constraints. A non-experimental before and after study involving bassline assessment of data accuracy and completeness, application of innovative strategies such as mentoring and coaching of Health Information Officers in data quality improvement process. Coincidentally, the intervention improved both data accuracy and completeness performance significantly among the participating facilities. The outstanding performance may be attributed to management's new orientation and growing interest towards quality data. Engaging frontline staff in data quality improvement work and provision of regular feedback leads to improvement in data accuracy and completeness. This has implications for decision-making and resource allocation, especially in low-income countries, where the routine health information management system relies heavily on paper work

    AngloGold Ashanti Iduapriem Mine is a surface gold mine which produces waste rock in its operations. The waste rock forms waste dumps which grow over the years, and will ultimately need to be closed down when they are filled to the maximum capacity. The mine has closure plans for the waste dumps and the closure activity will incur cost. This research was carried out to study the waste dump reclamation and closure plan for the Ajopa waste dump, and estimate the associated cost. The aim of the closure is to establish a permanent stable landscape that is environmentally compatible with surrounding undisturbed land. The waste dump will be closed with a progressive rehabilitation technique. The key activities involved in the reclamation plan, which are earthworks, capping and revegetation were identified and studied into detail. The reclamation plan and cost estimates were prepared on the basis that AngloGold Ashanti Iduapriem Mine would contract with a third-party contractor to fully execute the required closure and reclamation activities. The cost was then estimated using price quotes from vendors or contractors located around the mining area. Results showed that waste dump closure and reclamation programme for Iduapriem Mine are consistent with Ghana Mining and Environmental guidelines. The total closure and reclamation cost was estimated to be US$ 581 488.18. Since any delay in the closure and reclamation could incur additional cost, it was advised that the mine should execute the closure and reclamation plan without delay. Keywords: Waste Dump, Reclamation, Revegetation, Estimate

    Pre-and-In-Class Practical Lesson Habits of Selected University Physical Education Students in Ghana: Implications for Health and Physical Education

    Habits formed during schooling are probably the strongest that influence individuals throughout life. It is always the intention of curriculum planners that, habits formed by students as a result of schooling be positive to promote healthy lifestyle in the future. However, nothing is documented on the pre-practical physical activity habits of physical education (PE) students in universities in Ghana. The paper focused on common physical activity behaviours exhibited and the food products consumed by the students prior to and during PE practical lessons. We conveniently sampled 112 level 100-300 University of Cape Coast PE students during the 2012/2013 academic year. We developed a questionnaire to gather data for this study. We found that only 24% (n=27) of the students practice three times and over, the techniques taught in class before the next class. Also, 36% (n=40) of the students reported not using appropriate protective gears during practical classes. Beside, 35% (n=39) of the students would not do post-activity stretching without lecturers’ supervision. Of the products consumed, 9% (n=10) and 6% (n=7) take energy drinks prior to and during PE classes, respectively. Other 2% (n=2) take in alcoholic beverages before classes. However, 30% (33) consume nothing prior to morning practical lessons. Many university PE students in Ghana engage in many unhealthy habits that need attention. This paper discusses how this new knowledge can assist professionals in Health and PE to moderate the habits acquired and practiced by students while at school. Key Words: Pre-practical activity, pre-practical food consumption, physical education, physical activity habits

    Get PDF
    Background: This study describes the burden of bleeding oesophageal varices at the main tertiary referral centre in Accra.Design: Retrospective design to describe the endoscopic spectrum and review mortality data following acute upper gastro-intestinal bleeding at the Korle-Bu Teaching Hospital. Endoscopic data was reviewed in the Endoscopy Unit between 2007 and 2010. Mortality data was collated from the Department of Medicine between 2010 and 2013.Interventions: The study questionnaire compiled clinical and demographic characteristics, endoscopic diagnoses, length of hospital admission and treatment regimens. Main outcome measures: Aetiology and time-trend analysis of mortality rates following acute upper gastro- intestinal bleeding; variceal bleeding treatment modalities.Results: On review of the endoscopic diagnoses, gastro- oesophageal varices were identified in 21.9% of cases followed by gastritis 21.7%, duodenal ulcer, 17.0%, and gastric ulcer, 13.2%. Gastro-oesophageal varices were the predominant cause of death from acute upper gastro-intestinal haemorrhage from 46% in 2010 to 76% in 2013. Outcomes following acute upper gastro-intestinal bleeding were dismal with some 38% of fatalities occurring within the first 24 hours. Injection sclerotherapy was the dominant endoscopic modality for secondary prevention of variceal bleeding in comparison with band ligation, mainly as a result of cost and availability.Conclusions: At the tertiary centre in Accra, variceal bleeding is an increasingly common cause of acute upper gastro-intestinal haemorrhage in comparison with previous reviews in Ghana. Its significantly high in-hospital mortality reflects inadequate facilities to deal with this medical emergency. A strategic approach to care with endoscopic services equipped with all the necessary therapeutic interventions will be vital in improving the outcomes of variceal bleeding in Ghana.Keywords: gastro-oesophageal; varices; bleeding; gastro- intestinal, Ghana

    Many local butchers in Ghana have been using scrap tyres as substitute for firewood to singe slaughtered ruminants. This study analysed such singed hides from seven goats and three cattle in unregulated local slaughtering operations near the Kumasi abattoir, for risk of heavy metal contamination (Mg, Mn, Cu, Ni, Cd, Pb and Zn) using atomic absorption spectrometry. Relative to unsinged control hides, singed treatments generally elevated heavy metal levels in both goats and cattle hides. Magnesium, Mn, Cu, Ni and Cd concentrations in un-singed goats hide increased by 23, 29, 54, 24 and 20% respectively to 108.63 ± 3.85, 0.83 ± 0.13, 1.63 ± 0.13, 2.15 ± 0.29 and 2.26 ± 0.20 mg/kg in the singed material. Similarly, singeing increased Mg, Mn, Cu, Ni, Cd and Zn concentrations in cattle hide by 94, 49, 130, 33, 174 and 1055% to 80.0 ± 5.25, 2.13 ± 0.26, 5.67 ± 1.24, 3.50 ± 0.17, 4.20 ± 0.17, and 204.49 ± 36.69 mg/kg respectively. Lead concentration in cattle hide on the other hand decreased by 34% upon singeing, from 4.61 ± 0.30 mg/kg in un-singed controls to 3.06 ± 0.26 mg/kg in singed material. High concentrations of the metals in singed hides could not be entirely attributed to the singed treatment alone, in view of considerable background levels of heavy metals recorded in the un-singed samples; a situation that probably reflected a larger problem of heavy metal pollution in the local environment. Concentrations of Cd and Pb in hides were above maximum permissible levels (MPLs) of 0.05 and 0.01 mg/kg respectively set by the European Commission Regulation, whilst Zn was also above MPL of 50.0 mg/kg, according to the Meat Food Products Order of India. It was concluded that the hides were potentially unsafe for human consumption.Key words: Heavy metal contamination, meat products, singed treatments, consumed animal hide

    Impact of ERP Implementation on Business Process Outcomes: A Replication of a United States Study in a Sub-Saharan African Nation

    Get PDF
    This study is a conceptual replication of Karimi et al.’s (2007) study on the impact of ERP implementations on business process outcomes among US manufacturing firms in a Sub-Saharan African (SSA) nation. The results of the measurement model are valid and reliable, which are consistent and comparable with that of the original study, enhancing the external validity of the constructs proposed in the original model. However, only one of the four hypotheses tested in the structural model was confirmed in the current study although all four were supported in the original study. While the original model was tested on manufacturing firms in the US, the replicated study was carried out in several industries in Ghana, a SSA nation. Thus the differences in the structural model results do not invalidate the original model but suggest the need for capturing contextual or environmental variables such as culture, industry, ethical behavior, and data culture in order to enhance the external validity and theoretical contribution of the original model in the SSA context

    The execution of public projects is an indispensable recipe for socio-economic development in any country. However, the successful execution and implementation of public projects in Ghana has been hampered by payment delays. In the contrary little is known about the critical causes and effects of payment delays in the execution of public projects in Ghana. It is against this background the study was conducted to identify and rank the critical causes and effects of payment delay and to be able propose mechanisms and strategies for mitigating its pervasive. The study employed a case study sample survey as a research design within a quantitative research methodological paradigm to investigate the research problem. The random and purposive sampling techniques were employed to select 30 contractors, 10 consultants/experts and 10 clients.  The study therefore identified and ranked 10 causes and 13 effects of payment delays. It was realized that 8 out of the 10 causes of payment delays were considered critical because they all had mean score above the conventional mean 3.5 at 95% confidence on a five-point Likert scale with the top five critical causes of payment delay being; delay in certification (ranked no.1), poor financial management (ranked no.2), with holding of payment by clients (ranked no.3), ambiguous contractual provision (ranked no.4) and conflict among the parties (ranked no.5).   It was also revealed that 11 out of the 13 effects identified including the top five consequences of payment delays included; leads to abandonment of projects (ranked no.1), results in cost overrun (ranked no.2), results in delay in completion of the projects (ranked no.3), leads to bankruptcy/liquidation (ranked no.4)  and results in time overrun (ranked no.5) were considered critical. Based on the findings the study recommended that payment delay could be minimized if Proper payment schedules are been agreed by all the parties before the commencement of the project accompanied by regular communication between parties and prior anticipation cost overrun and time overrun in clear contractual provision. Keywords: critical causes, effects of payment delays, execution of public projects, fresh evidence, Ghan

    Education and Employment Outcomes in Ghana through the Lens of the Capability Approach

    Get PDF
    Existing literature on education and employment confirms that in Ghana educational qualification largely influences the type of work. Through the lens of the Capability Approach, which sees human development in terms of the expansion of freedoms and opportunities, this paper identifies, for a cross-section of Ghanaians, the array of employment opportunities between and within education endowments. “Between endowments” refers to differentials in opportunities for individuals with different levels of educational qualifications, while “within endowments” considers the differentials for individuals with the same level of education. The source of data is the 2005/06 Ghana Living Standard Survey (GLSS5). Results show that education is not enough to erase inequalities. Multinomial regression analysis demonstrates that functionings differ according to the individual’s context, household and personal conversion factors. This is explained by inequalities in the requirements for a particular job (between educational endowments) and by job accessibility due to personal characteristics (within educational endowments)

    Objectives: To determine the rate and factors associated with viral load non-suppression among adults living with HIV/AIDS on active anti-retroviral therapy (ART).Design: A retrospective cross-sectional studySetting: Three ART clinics in Kumasi, GhanaParticipants: All HIV-infected adults who were ≥18 years and on active ART for 12 months and whose viral loadnhad been estimated were included.Main outcome measure: Unsuppressed viral load among patients on ARTResults: In all, 483 HIV patients were included in the study, with 369 (76.4%) achieving viral load suppression. Gender, educational level, comorbidity status, and duration on ART were independently associated with viral nonsuppression (p < 0.05).Conclusions: This study has revealed that the rate of viral suppression in the study area is lower than the UNAIDS 90% target. The findings have implications on designing new and stemming up implementation of existing interventions to improve the rate of viral suppression among patients in the study area. It is also necessary that more of such studies are replicated in other parts of the country to identify risk factors for virological failure among patients on ART
