    Connecting People using Latent Semantic Analysis for Knowledge Sharing
    (2010-01) Mugo, David M.
    A shift from technology-oriented knowledge management to people-oriented knowledge management is indispensable. To achieve this, organizations must understand the nature of knowledge. In this work, knowledge has been found to be both a process and a collection of artifacts. This makes knowledge and the knower to be two inseparable entities. Consequently, the appropriate way to share both the explicit and the implicit knowledge components is through people-with-people connection. However, from existing barriers like location and time differences among others, people-with-documents connection is proposed as an intermediate step. The investigation of latent semantic analysis (LSA) in achieving people-with-documents connection has revealed decreased precision performance at higher recall performance. A solution to include annotations in the technique has been proposed to refine knowledge representation into the LSA technique. Annotation process based on domain ontologies has been proposed to compliment the LSA knowledge mining process from documents with domain knowledge represented by ontologies

    Determinants of Electronic Health in Developing Countries
    (2014-04) Mugo, David M.; Nzuki, David
    Limitations of paper-based records are influencing a transition across the globe towards Electronic Health Records (EHRs) and in general electronic health (eHealth). However, despite the well documented benefits of eHealth, adoption particularly in developing countries remains a great challenge. Lessons learned from widespread implementation efforts can be used to encourage and inform the use of eHealth. This study evaluates the most current literature to establish the extent to which electronic health has been adopted in developing countries. The study has shown various determinants of electronic health adoption which will help countries particularly the developing ones come up with necessary interventions to accelerate the adoption. As part of future work, more studies need to be done, firstly to confirm the effect of the mentioned determinants in this paper in each developing country, secondly to find out other determinants of eHealth adoption and thirdly to show how developing countries’ cooperation on eHealth strategies can affect the journey towards eHealth adoption by these countries.

    Effect of Mobile Communication Services on Performance of Saccos in Kenya
    (2018-10) Mugo, David M.; Muathe, S.M.A; Waithaka, Stephen T.
    The ubiquitous nature of mobile technologies and devices, present new challenges and opportunities for Deposit-Taking Savings and Credit Cooperative Societies (SACCOs) as they integrate them into their processes with the hope of improving their performance. To enhance their performance, Deposit-Taking SACCOs have adopted and are using mobile communication services including mobile messaging, mobile call services, mobile email, mobile chatting and mobile conferencing services. However, the effect of these mobile communication services on performance of Deposit-Taking SACCOs has not been well studied. Even though some studies have indicated the positive potential of mobile communication services, other studies indicate that they have no effect on organizational performance. Given these contradictions, this study sought to investigate the effect of mobile communication services on performance of Deposit-Taking SACCOs in Kenya. Descriptive and explanatory research designs were adopted using quantitative and qualitative approach to data collection, analysis and reporting. The study used a sample of 86 Deposit-Taking SACCOs drawn from a target population of 110 Deposit-Taking SACCOs that were licensed by SACCO Societies Regulatory Authority as at 31st December 2011. A structured questionnaire administered to two managers (from information technology and finance departments) in each SACCO was used to collect primary data. Inferential analysis revealed the exististence of statistically significant positive effect of mobile communication services on performance of Deposit-Taking SACCOs in Kenya. The study therefore recommends investments and increased utilization of mobile communication services within DepositTaking SACCOs in Kenya.

    An Investigation of the Latent Semantic Analysis Technique for Document Retrieval
    (2014) Mugo, David M.
    Latent semantic analysis (LSA) application in information retrieval promises to offer better performance by overcoming some limitations that plagues traditional termmatching techniques. These term-matching techniques have always relied on matching query terms with document terms to retrieve the documents having terms matching the query terms. However, by use of these traditional retrieval techniques, users’ needs have not been adequately served. While users want to search through information based on conceptual content, natural languages have limited the expression of these concepts. They present synonymy problem (a situation where several words may have the same meaning) and polysemy problem (a situation where a word may have several meanings). Due to these natural language problems, individual words contained in users’ queries, may not explicitly specify the intended user’s concept, which may result in the retrieval of some irrelevant documents. LSA seems to be a promising technique in overcoming these natural language problems especially synonymy problem. It deals with exploiting the global relationships between terms and documents and then mapping these documents and terms in a proximity space, where terms and documents that are closely related are mapped close to each other in this space. Queries are then mapped to this space with documents being retrieved based on similarity measures. In this report, LSA performance in documents retrieval is investigated and compared with traditional term-matching techniques.

    Medical Device Integration with Electronic Health Records: A Case Study of University of Nairobi Health Services, Kenya
    (2020-06) Nzyoka, Benard Mutisya; Mugo, David M.; Ng’ang’a, Stephen M.
    In this study, we describe a demonstration in which available electronic medical records system (EMR) was successfully integrated with a wireless blood pressure monitor (BPM). This was implemented by adopting the use of RESTful Application Programming Interface (API) technologies and commonly established standards designed for medical devices interoperability. Before deploying the prototype, we conducted pilot tests at the University of Nairobi, nursing station to get feedback on the time spent using the conventional blood pressure data capture methods and the newly integrated application. Clinical data from the device was exchanged adhering to the HL7/XML standard communication protocol. The findings indicate a positive outcome was availed on the time taken for the blood pressure readings, time spent by the patient at the nursing station, doctor’s time to search the patients’ blood pressure readings as well as the data accuracy fed in the EMR system.

    Moderating Effect of Government Policies on the Relationship between Mobile Technology Services and Performance of Deposit-Taking Saccos in Kenya
    (IJSET, 2017-02) Mugo, David M.; Waithaka, Stephen T.; Muathe, Stephen
    The study sought to determine the moderating effect of government policies on the relationship between mobile technology services and performance of Deposit-Taking Savings and Credit Cooperative Societies (SACCOs) in Kenya. Descriptive and explanatory research designs were adopted based on a sample of 86 Deposit-Taking SACCOs. A structured questionnaire administered to two managers in each SACCO was used for data collection. The study found that government policies positively moderates the relationship between mobile technology services and performance of Deposit-Taking SACCOs implying that appropriate government policies that are favourable for the Deposit- Taking SACCOs should be formulated.

    Performance Analysis of Debit Card Services on Deposit-Taking SACCOs’ Financial Performance: A Case of Kenya
    (Kennesaw State University, 2019-04) Mugo, David M.; Muathe, Stephen; Waithaka, Stephen T.
    The Co-operative Bank of Kenya has partnered with Deposit-Taking Savings and Credit Cooperative Societies (SACCOs) in Kenya to allow their members access to Co-operative Bank automated teller machines (ATMs) via Saccolink debit cards. However, the adoption and utilization of debit cards has opened financial institutions to fraud associated with the use of debit cards for transactions on automated teller machines and point-of-sale terminals. Given this limitation, this study sought to investigate the effect of Saccolink debit card services on the financial performance of Deposit-Taking SACCOs in Kenya. Through a combination of agency, information systems success models, and task-technology fit theories to explain financial performance, the study found a positive effect of Saccolink debit card services on the financial performance of Deposit-Taking SACCOs in Kenya. The study therefore recommends continued utilization of Saccolink debit cards and an enhancement of their features within the Deposit-Taking SACCOs in Kenya.
