Comparative Study of the Current Processes used by Insurance Companies and application of Block Chain Technology on Business Performance in Kenya
(International Journal of Science and Research, 2020) Shitanda, Douglas; Kanuku, Musyoki; Nganu, Margaret
The insurance industry has been engaging in numerous processes which are characterized by the exchange of data updated by multiple parties, they have ramped up investments in their digital agenda to be at par with other industries. However, despite of such enormous investments, thousands of fraud cases have been reported and many more could have gone unreported on the same platforms intended to increase efficiency. Blockchain, as a single source of truth, has the potential to increase transparency, efficiency and reduce the complexity of these processes. This research was carried outto comparethe current processes used by insurance companies and influence of block chain technology on business performance in Kenya. The specific objectives of the study were; To establish the procedures used by insurance companies in Kenya;to establish the challenges of the current processes used by insurance companies on business performance;to establish the level of awareness in insurance companies on block chain technology on their business performance and to establish the awareness of the benefits of block chain technology on business performance of insurance companies. The study was descriptive in nature, both qualitative and quantitative data was collected. Stratified random sampling technique was used to select 16 companies out of the 52 insurance companies registered in Kenya, based on their domain of operation. The findings of the study were; there is no common procedures for all insurance companies in Kenya even those operating in the same domain;communication between clients and company, verification of payment details, misappropriation of clients’ premiums, missing records of payments, legal reporting systems are the key challenges facing receiving and making client’s payment; Lack of transparency between the parties involved in receiving payments, management misunderstanding, legal reporting systems fraudulent transaction, presentation of fictitious claims, provision of correct information/data, communication between the client and the company, misappropriation of clients’ payments, missing record of payment, verification of payment details are the risks involved in making payment to clients. Most organizations are aware of block chain but have not implemented it in their processes. The following were identified as the key benefits insurance companies can enjoy by adopting block chain technology; reduce fraud; fasten claim settlements;increase transparency among parties;increase data security and integrity; increased speed of digitization and reduce back end tasks. There is need for policy guideline on operations of insurance companies. The study recommends further research to be done on challenges that insurance companies face in adopting block chain technology.
A Stage Model for Cloud Computing Adoption in E-Government Implementation
(International Journal of Science and Research, 2017) Kanuku, Musyoki; Boit, Judith
As Governments continuously look for ways to improve their service provision, there is need for restructuring processes and effectively using technology to improve efficiency and effectiveness of their functions. Cloud computing is one of the recent technological trends that support these efforts. The promise of cloud computing has captivated organizations globally. Considering eGovernment is one of the sectors that is trying to provide services via the internet, cloud computing is a suitable model for implementing e-Government architecture to improve e-Government efficiency and user satisfaction. The challenge comes in the adoption process. Organizations are faced with question of how to best adopt cloud computing. Existing frameworks of cloud adoption look at different aspects of cloud but stop short of taking a view of the complete spectrum and suggesting adoption path. This study takes a concept centric approach by proposing a stage model for adoption of cloud computing in e-Government. The objective of the model is to help plan about the path to cloud, especially when it is so ‘Cloudy’ and evolving. The organizations at different stages of cloud adoption exhibit different characteristics and possess distinct competencies, and organizations should not bite more than they can chew, lest their programs fall flat. In this study, the adoption of cloud computing in implementing e-Government services was done through primary research and system modelling. Out of which, a stage model was developed proposing an adoption path for cloud computing in eGovernment services. The model will guide Governments in creating cloud-computing strategy by identifying the distinct stages in progression. This makes stage model the most suitable for adoption of cloud computing in e-Government
Application of M-Gov to Provision of Education for all in Developing Nations
(Horizon Research Publishing, 2014) Maake, Benard; Mzee, Awour Fredrick
Due to advances in wireless and mobile technology, a lot of applications have been developed in the areas of health, entertainment, education, agriculture, education among other to harness the benefit of this technology and to provide services closer to the users. In addition, this technology enables the government and private sectors to deliver, manage, organize and disseminate services to public in an more efficient and economical manner. Providing quality and free for all education that is readily accessible is critical in developing countries where most citizens live on less than a 1 USD a day. In these countries, most learners trade off time for education for casual work to earn a living. In such a case, the learners are denied right of access to quality and free education. It is therefore important to illustrate how education managers could adapt mobile and wireless technology to facilitate, control and manage capacity development towards the achieving education for all In this paper, we explore the benefits of mobile governance (m-Gov) of educational resources as a tool to deliver free, quality and accessible education. The paper argues that such an ICT application needs to incorporate all the education stakeholders to attain accountability and transparency on provision of education services. The paper also illustrates the key concepts in implementation of the argued ICT application i.e., m-Gov.
Vitamin B12 and Coenzyme Q10 Ameliorated Alcohol Driven Impairment of Hematological Parameters, Inflammation, and Organ Damage in A Mouse Model
(Springer Nature Switzerland, 2023) Nyabuga, Nyariki James; Kipchumba, Biwott; Orina, Isaac Alfred; Mwaeni, Victoria K.; Omwenga, George; Ngugi, Mathew
Introduction Chronic alcohol consumption is associated with a myriad of negative physiological and biochemical changes in humans. Vitamin B12 and coenzyme Q10 (CoQ10) are novel antioxidants and anti-inflammatory agents. Purpose The objective of this study was to determine the impact of oral supplementation with vitamin B12 and CoQ10, in attenuating deleterious effects associated with alcohol exposure in Swiss albino mice. Methods Group one was normal control, the second group received 5 g/kg alcohol; the third group received 6 mg/kg b/w of vitamin B12 and 5 g/kg alcohol; the fourth group received 6 mg/kg b/w of vitamin B12, 200 mg/kg b/w CoQ10, and 5 g/ kg alcohol, the fifth group 200 mg/kg b/w of CoQ10 and 5 g/kg alcohol. Results Oral administration of vitamin B12 and CoQ10 alone or in combination significantly ameliorated alcohol-induced impairment of hematological parameters and stabilized alcohol-induced alteration of the lipid profile. Notably, administration of either vitamin B12 or CoQ10 significantly blocked alcohol-induced depletion of reduced glutathione levels. Furthermore, vitamin B12 and CoQ10 stabilized the levels of pro-inflammatory cytokines (TNF-α and IFN-γ) when administered alone or in combination. Remarkably, the administration of CoQ10 and vitamin B12 significantly attenuated alcohol-induced liver and kidney inflammation and pathology. Conclusion Administration of either vitamin B12 or CoQ10 alone or in combination can protect from the toxic effects of chronic alcohol exposure.
Sodium Metabisulfite-Induced Hematotoxicity, Oxidative Stress, and Organ Damage Ameliorated by Standardized Ginkgo biloba in Mice
(Journal of Toxicology, 2023) Nyabuga, Nyariki James; Wambui, Wairimu Nancy; Wairagu, Peninah; Chepukosi, Kennedy W.; Obiero, George F.; Okanya, Patrick W.; Orina, Isaac Alfred
Sodium metabisulfte (SMB) is a biocide and antioxidant agent generally used as a preservative in food and beverage industries but can oxidize to harmful sulfte radicals. A standardized Ginkgo biloba (EGb-761) has demonstrated potent antioxidant and antiinfammatory activities, which is benefcial for the treatment of diseases that exhibit oxidative stress and infammation. Te present study sought to investigate the putative ameliorative efects of EGb-761 against SMB-induced toxicity in mice. Tirty-twomale Swiss white mice were randomized into control, SMB-treated, SMB + EGb-761-treated, and EGb-761-treated groups. EGb761 (100 mg/kg/day) and SMB (98 mg/kg/day) were administered by gastric gavage for 40 days. Oral administration of EGb-761restored SMB-induced decrease in body weight and prevented SMB-induced thrombocytopenia, leukocytosis, and anemia.Furthermore, EGb-761-treatment protected against SMB-induced liver and kidney injury depicted by decreased serum levels ofaspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase, bilirubin, creatinine, urea, uric acid, and albumin. Furthermore, EGb-761 treatment attenuated SMB-driven dyslipidemia and metabolic acidosis. Besides, EGb-76 supplementation abrogated SMB-driven oxidative stress as depicted by stabilized reduced glutathione (GSH) levels in the brain, liver, kidney, spleen, heart, and lungs. SMB induced a signifcant increase of tissue levels of malondialdehyde (MDA), serum nitric oxide (NO), interferon-gamma (IFN-c) and tumor necrosis factor-α (TNF-α) which were abrogated by EGb-761 treatment. In conclusion, these results deepen our understanding of EGb-761 in light of various detrimental efects of SMB-driven toxicities.These findings provide a novel approach that can be optimized for preventing or treating exposure due to SMB toxicity
