A review of distributed ledger technologies application in medical systems interoperability

Dorothy Gatwiri Bundi — 2024-04-22

This study of the literature delves into the complex area of medical systems interoperability, focusing on mitigating variables that impact security and data transfer at the structural and semantic levels. In the era of digital healthcare, the secure sharing of medical data is crucial, and this study looks at how Distributed Ledger Technologies (DLTs) can play a major role in addressing these challenges. Complex interoperability issues that come from differences in communication protocols, data formats, established data structures, data models, and data meaning and codification methodologies face the healthcare industry. These problems typically impede the seamless transmission of electronic medical records between healthcare systems. Because of their decentralized structure and cryptographic foundation, DLTs offer a workable solution to these issues. By critically evaluating previous research and case studies, DLTs may be able to lessen these interoperability issues, as this literature review illustrates. Since DLTs provide an immutable and secure platform for the transmission of medical data, guaranteeing data integrity and confidentiality, they are a natural fit for the sensitive nature of healthcare data. Their importance in creating safe communication protocols, enhancing the meaning of data, and defining models and formats for data is emphasized in this review. A comprehensive architecture for DLT interoperability in healthcare is also recommended by the research. This framework encourages the development of DLT integration, shared data models, standardized data formats, and governance and policy. By implementing this strategy and strengthening secure medical data sharing, healthcare organizations and governments may increase the efficiency, precision, and speed of healthcare delivery. The crucial role that DLTs play in removing the structural and semantic barriers to safe medical systems interoperability is highlighted in the conclusion of this literature review. By adopting DLTs, the healthcare sector may usher in a new era of standardized, safe, and efficient medical data transmission, which will ultimately benefit both patients and healthcare providers. This study shows how distributed ledger technologies (DLTs) have the potential to revolutionize the healthcare industry by enabling the secure and meaningful exchange of medical data between different systems, thereby improving patient care and healthcare outcomes.

To support learners in selecting career pathways that match their interests and competencies, recommender models are widely used. Recommender models (RM) analyze learners' competencies, interests and goals to suggest career pathways suited for them. This paper reviews literature by analyzing recommender models used for career pathway selection in CBE through desk study. First, it explains the concepts of CBE. Secondly, it discusses the types of recommender models used for career pathway selection in CBE. Lastly, it discusses various recommender models developed for career pathway selection highlighting their strengths and weaknesses. Findings from the review reveals that hybrid recommender model is popularly employed for career pathway selection compared to content-based, knowledge-based, and collaborative filtering recommender models as it gives a higher level of accuracy in the recommendation. Overall, this review paper contributes to the growing body of literature on recommender models for career pathway selection in CBE. In addition, it provides valuable insights for practitioners, researchers and emphasizes the need for future research to address the challenges associated with recommender models for career pathway selection in CBE.

Performance validation for an Internet of Things (IoT)-based Model for hydro-electric monitoring

Lisper Mutwiri — 2024-04-22

Globally, hydro-power has been considered the cheapest renewable source of energy. This form of energy production entirely depends on the water levels which in turn causes a major concern of ensuring that the monitoring systems involved are capable of ensuring monitoring in the prevention of disasters. The disasters involved range from floods and drought conditions that would lead to low power production led by lack of enough water draining in the reservoirs'. Several systems have been implemented to come up with a convenient and efficient monitoring system. With the freedom given to software developers in developing the procedures, an evaluation of the system's performance must be performed to enable this transformation. Therefore, the study selected an already existing real-time monitoring system using Lora Technology in hydroelectric monitoring to conduct the performance validation. A total of one hundred and twenty readings were taken to be validated with the other models used. Consistency, accuracy, latency, and throughput were used to validate the IoT-based model's performance. During the performance validation, the study found that the system achieved all the functionalities expected in its assessment. Therefore, IoT-based systems have the potential to inform future hydroelectric monitoring practices.

Assessing usability of University websites in meeting the expectations of students: a survey of literature

Gitonga Imathiu — 2024-04-22

University websites are gateways to display resources offered by an institution (Mentes, 2012). As such first impression, attractiveness, controllability, helpfulness, efficiency and learnability as defined by Website analysis and measurement inventory (WAMMI) (Jabar et al., 2013) is critical in the design of websites. Unfortunately, most Universities Websites design are often driven by technology, organizational structure, or institution's objectives, rather than by its usability from the perspective of students (Undu & Akuma, 2018). This reduces chances of converting a prospective student into a current student after failing to get inquiries into enrollment opportunities in the university. To increase the usability of University websites it is necessary to increase the visibility and accessibility of all website related content. This result into the need of evaluating university websites a process that is very vague and a times usually unknown to most developers, which adversely then impacts the student experience when visiting such websites. To address this problem, standard usability metrics need to be considered to examine the university websites to analyze whether these websites are able to meet the requirements of customer number one who is the student. These metrics comprise of ease of use (simplicity), design (layout), navigation, organization, communication and content. Qualitative and quantitative approaches were used by different researchers to evaluate processes involved by analyzing questionnaires responded to by students after browsing several university websites. In addition, various technological innovations aimed at increasing and improving the web presence were used which involved re-designing of websites using the latest state of the art technologies so as to improve its usability as well as use of automated tools like Web Accessibility checker, HERA and WAVE. After reviewing different literature a valuable insight on key Usability, attributes for websites are noted to be of essence in designing website to meet students’ expectations.

A systematic review of predictive blood donor retention models.

Nahashon Kiarie — 2024-04-22

Demand for blood and blood products is increasing due to population growth, medical advances, and increased disease. Availability of a stable blood supply is critical for healthcare organizations and requires effective donor recruitment and retention strategies. This systematic review paper examines the development and implementation of predictive models using machine learning techniques to classify and predict blood donor retention rates. The aim is to analyze the existing literature and provide insights into the design, performance and potential of such models through a systematic search of relevant databases. The reviewed studies include a variety of machine learning approaches and algorithms used to predict blood donor retention rates. These models use various demographic, behavioral, and historical donation data to predict the likelihood of a donor returning to donate blood. The utilization of machine learning techniques, such as decision trees, logistic regression, support vector machines, and neural networks, enables accurate predictions and enable healthcare organizations to implement targeted donor retention interventions to increase blood supply. The models' predictive performance reveals their capacity to recognize donors who are not likely to return and donate blood and target retention strategies appropriately, improving donor engagement and fostering long-term commitment. Several challenges and limitations face the identified existing models. They include the need for comprehensive and high-quality data, interpretability of complex models as well as the requirement for regular model updates to accommodate changing donor behaviors. There is need for development of versatile and comprehensive models with improved accuracy that can reduce the need for constant recruitment of new donors, which is costly and time-consuming enabling blood agencies to accurately predict donor retention rates, inform donor retention strategies, and prioritize resources appropriately and ultimately saving lives.

Evaluation of sulfuric acid effect on bending strength of steel used in concrete reinforcement in sanitation structures

Samuel Okoth Athiambo — 2024-04-23

Most sanitation structures in the world are constructed using concrete which is reinforced by the steel, this type of concrete is called Reinforced Cement Concrete (RCC). The RCC structure is believed to be relatively resistant to corrosion which the sanitation structures are prone to due to the aggressive environment in which they are subjected to. This belief has been compromised since the reinforced concrete used in the sanitation structures such as the concrete sewer pipes has become susceptible to Microbiologically Induced Deterioration (MID). This MID leads to degradation and compromised strength and service life of the RCC. In the reinforced concrete structure, the backbone of this structure is the reinforcing steel which when its strength is compromised by the MID, the whole structure is compromised. The present research therefore aimed at evaluating the effects of sulfuric acid, resulting from the MID process, on the bending strength of steel metal used for reinforcing concrete in sanitation structures. Reinforced concrete specimens were developed using different types of cement and different concrete cover. The three different types of cement were, Ordinary Portland Cement (OPC), Portland Pozzolana Cement (PPC) and Limestone Calcined Clay Cement (LC³), while concrete covers of 15mm and 25mm were applied. They were then subjected to a harsh environment (a sample of sewage) suitable for corrosion just like in their actual operational environment. To determine the effects of sulfuric acid resulting from MID on the steel metal, the steel metal was tested using a Universal Testing Machine (UTM). The bending strengths before and after being subjected to an aggressive environment were determined. The testing of the specimens was done at an interval of 14 days for a period of three (3) months. According to the results, for a concrete cover of 25mm, LC³ showed a minimum percentage reduction in strength compared to PPC and OPC. It had the lowest percentage reduction in strength after 84 days which was 5.25%, OPC 7.20%, and PPC 7.24%. In conclusion, there was a strength reduction for all specimens tested. LC³ showed good resistance to the effects of MID compared to PPC and OPC. In terms of concrete cover, 25mm showed good resistance to MID compared to 15mm concrete cover.

Effects of biogenic sulfuric acid on simulated concrete septic tanks

Simon Irungu Gachie — 2024-04-22

Concrete is the major construction material for infrastructure development. Concrete sewer septic tanks are Constructed using the conventional ordinary portland cement (OPC) and the Portland pozzolana cement (PPC). However, OPC based concrete sewer systems are susceptible to biological, mechanical, and chemical degradation. Degradation of the concrete septic leads to their failure hence imposing tremendous environmental problems. The aftermath is the emergence of sanitation-related diseases. The wastewater from failing septic systems leads to contamination of the groundwater or the surface water resulting in the pollution of drinking water. Therefore, the need to explore other possibilities and potential construction materials to achieve sustainable sanitation is inevitable. The use of Limestone Calcined Clay Cement (LC3) in the construction of degradation-resistant concrete sewer septic systems has not been well explored in Kenya. LC3 concrete is resistant to the deterioration effects of aggressive media such as acids, chlorides, and sulfates. This paper presents experimental performance and findings of LC3 in aggressive media vis a vis OPC. The LC3 was formulated by mixing clinker, Calcined clay, limestone, and gypsum at percentages of 50 %, 30 %, 15 %, and 5 % respectively. Compressive strength, Sorptivity, and weight loss during the wet and dry cycles for both LC3 and OPC were evaluated. Simulated concrete septic tanks made of LC3 and OPC were made by casting cubes at water cement ratio of 0.5 and cured in fresh water at ambient temperature for 28 days. These cubes were passed through a regime of W-D cycles in the 3% concentration of Biogenic sulfuric acid. It was observed that after 28 days of curing OPC cubes had slightly higher compressive strength than LC3. However LC3 concrete cubes are expected to have higher compressive strength than the OPC. Cubes curing time increases due to increased pozzolanic activity. Biogenic sulphuric acid attacks on hydrated cement products cause a decrease in compressive strength. The water absorption profile of LC3 cubes was lower as compared to OPC cubes. In conclusion, LC3 cubes had a high potential of resisting degradation as compared to OPC cubes. LC3 show more impressive performance, hence LC3 It’s a potential binder for use in the construction of sewer system.

Keywords: Septic tank, Sorptivity, compressive strength, wet-dry cycles, biological, mechanical, and chemical degradation, sustainable sanitation, LC3.

Webometrics ranking of Universities: fallacy or reality

Simon Thuranira — 2024-04-22

In recent years, the utilization of webometrics as a tool for ranking universities has gained significant traction, purportedly offering a comprehensive assessment of institutions' digital presence and impact. However, amidst its growing popularity, questions arise regarding the validity and applicability of webometrics rankings, particularly concerning universities situated in the global south. This paper critically examines the webometrics ranking system, aiming to discern its strengths and weaknesses while scrutinizing its efficacy in evaluating universities, particularly those in regions with diverse socio-economic contexts and digital infrastructures. The analysis begins by delineating the fundamental principles underlying webometrics rankings, highlighting its reliance on web-based indicators such as web presence, visibility, and transparency. While these metrics ostensibly offer insights into universities' global reach and influence, they also engender methodological complexities and biases. Notably, the dominance of older well-endowed institutions in comparison with younger resource-constrained institutions impeding equitable evaluation. Furthermore, the paper investigates the specific challenges faced by universities in the global south within the webometrics framework. Issues of digital divide, limited internet penetration, and disparities in web accessibility compound the difficulties faced by these institutions in attaining favorable rankings. Moreover, the emphasis on quantitative metrics overlooks qualitative aspects of academic excellence, neglecting factors such as research impact, teaching quality, and societal relevance, which are integral to universities' roles in diverse contexts.Through a critical lens, this paper underscores the fallacies inherent in the uncritical adoption of webometrics rankings as a singular measure of university performance. It advocates for a nuanced approach that acknowledges the contextual nuances and challenges faced by universities, particularly in the global south. By fostering a dialogue on the limitations of webometrics and exploring alternative evaluation methodologies, this research aims to contribute to a more inclusive and equitable framework for assessing higher education institutions in an increasingly digitized world.

Innovative pedagogy of competence based training in horticulture: case stuy of TVET Education in Kenya

Peter Masinde — 2024-04-22

Horticulture is the fastest growing sub-sector in Kenya. It contributes the most towards the envisioned poverty reduction, and overall food security. It is generally a labour-intensive industry with high demand of skilled workers, trained supervisors and professional managers. Most Agricultural Technical and Vocational Education Training colleges (ATVETs) have a very general focus and there is lack of specialized and competent workforce in horticulture. The training is classroom and institutional centred with limited access to necessary resources and facilities, and limited interactions with industry and world of work. In this project, a consortium of partners worked with selected ATVETs to close the skills gaps using a non-traditional pedagogy of competency based training in horticulture. This was by strengthening the capacity of the ATVETs through a strong collaboration and linkages between the education institutions and the private sector to enable practical learning and innovation in the horticulture sector. The project integrated the curriculum for horticulture, water and climate to suit the needs of the students and the labour market, and tailored it to the local context. Each of the participating colleges invested in hands-on training through dedicated agricultural innovation hubs and creating strong links with the local stakeholders. To compliment curricula developed by the Curriculum Development Assessment and Certificate Council (CDACC), training manuals were developed for selected courses. In addition tutors were trained to enhance their capacity in design, delivery and evaluation of competence based education. Problem based learning in the Kenyan context as well as joint learning sessions between Kenyan and Dutch students were the other non-traditional pedagogy methodologies that were explored. The project increased interactions between the ATVET, industry and partners in horticulture within Kenya and in the Netherlands. The ATVETs created more local partnerships relevant to their training and practical work. The students were the primary beneficiaries through enhanced quality teaching. These benefits have been cascaded to the surrounding communities and the impact is expected to be sustainable.

The perception of the teacher trainees on the implementation of e-assessment in the selected Teacher Training Colleges in Kenya

Edwin Kubai — 2024-04-22

The Kenya National Examinations Council (KNEC) is currently implementing the integration of technology in conducting assessments to replace the traditional mode of paper and pen. The purpose of this study is to examine the perception of the teacher trainees towards the implementation of e-assessment in the upgrade course of the Diploma in Primary Teacher Education (UDPTE). The study adopted a descriptive research design and was carried out in two (2) public teacher training colleges with a target population of two hundred and forty (240) teacher trainees for the UDPTE programme. All the trainees in the sampled colleges were purposively selected to participate in the study since all of them had participated in the formative e-assessment. An online Teacher Trainees Questionnaire (TTQ) was used to collect information relating to trainees' perception of e-assessment. The reliability coefficient alpha (α) of TTQ was found to be 0.78 from the pilot study making the instrument valid for data collection. The data collected was analyzed using both descriptive and inferential statistics by the use of SPSS software version 26.0. The study findings established that a significant number of teacher trainees were upgrading in Option B as compared to Option A learning areas. The teacher trainees believed that the best way to finance the Upgrade of Diploma in Primary Teacher Education program (UDPTE) in Kenya was by using bursaries or scholarships and not loans. A significant number of teacher trainees support the adoption of e-assessment but they are of the view that the colleges were not yet prepared due to lack of necessary technological infrastructure. It was further noted that the teacher trainees need more training on basic computer skills in order to improve their typing skills for responses to enhance the complete submission of assessments on the portal in their respective learning areas. The Ministry of Education needs to equip the teacher training colleges with the necessary technological infrastructure and continuously retool tutors on how to integrate technology tools in the assessment procedures.

Jacinta Mukiri — 2024-04-22

The study sought to analyze roles of secondary school principal in implementing Competency Based Curriculum (CBC) in Tigania west Sub County. The objectives of the study were; determining leadership skills possessed by principals in secondary schools; establishing availability of resources used by principals; examining how principals involve teachers in monitoring and evaluation; and establishing ways in which principals are involving parents in implementation of competency based curriculum. The study was conducted using descriptive survey design. The target population in the study was 867 participants; 51 principals, 255 HoDs, 510 teachers, and 51 parents in the study area. The sample size of 10 principals, 30 HoDs, 60 teachers and 10 parents were selected using Yamene sample size tables. The test instruments used to collect data were questionnaires, observation checklists and interviews. Quantitative data was analyzed using descriptive statistics while qualitative data was coded analyzed and interpreted using statistical packages for social sciences version 20.0 and summarized into frequency tables, pie charts and bar charts. The response rate was 98.5%. The findings of the study revealed that; principals use democratic and transformational leadership styles which inspire teachers to interact with other teachers; enhance cluster setting of exams, marking and attending workshops together which enhance assessment of learners. In addition, parents are involved in junior secondary school because since CBC had not started in senior Secondary schools. From the findings, the study concluded that, 80% of the secondary school principals are not ready to implement the Competency Based Curriculum due to resource constraints and in-service training of teachers. The study also found that, parents are not much involved on the implementation of Competency Based Curriculum (CBC) in the secondary schools in Tigania West Sub- County in Kenya

The influence of economic factors on feacal emptying, conveyance and disposal:

Silvanus Mark Owuor — 2024-04-22

Safe management of faecal waste is one of the Sustainable Development Goals (SDGs) which envisions safe sanitation for all. However, although efforts to improve sanitation conditions in slums have been made, faecal emptying, conveyance and disposal still remain a challenge endangering the health of the public. The study examined the influence of economic factors on faecal emptying, conveyance and disposal in on-site sanitation facilities in Meru slums. A convergent design with a mixed methods approach was adopted. Quantitative data was collected using structured questionnaires from a sample of 228 household heads selected using cluster and proportionate simple random sampling techniques. Correlation and regression analysis was carried out to ascertain the association between emptying, conveyance and disposal of faecal waste and the economic factors. Qualitative data was gathered using focus group discussion participants with eight (8) who included four (4) pit operators, 3 household heads and 1 Public Health Officer (PHO) and results analyzed thematically. Findings showed that only 31% of slum dwellers emptied latrine pits and that manual emptying was more common (84%) than mechanical emptying because of its cost efficiency, reliability and the effectiveness in handling plastics, glasses, metal pieces, diapers and sanitary pads contained in pits. Increased cost constrained faecal emptying, conveyance, and disposal (r=0.499, p-value=0.000). Residents who were able to pay for faecal handling services were more likely to practice hygienic faecal emptying, conveyance, and disposal (r=0.524, p-value=0.000). Low level of income for majority of slum dwellers influenced the design of the latrines adopted. Emptying faeces from poorly designed pit latrines was more expensive due to operators’ safety concerns. The study concluded that the inability to meet the costs associated with faecal emptying, conveyance and disposal services facilitated poor sanitation status in slums. There is need to sensitize the slum community on the benefits of practicing safe management of faecal waste. The study recommended development of government policies to regulate mechanical emptying conveyance and disposal of faecal matter.

Teresia Mucia Kariuki — 2024-04-22

Accessing basic sanitation services is still a challenge in slums and sanitation needs of some groups specifically women at times remain unmet. This study assessed the socio-economic factors that influence the utilization of sanitation facilities by women at Mukuru Kwa Reuben, Kenya. The study targeted women aged 18 and above who consented. The Sample size was 395 women at Mukuru Kwa Reuben. Clustered and simple random sampling techniques were utilized to select the study participants. The data collection tools were questionnaires, focus group discussions and observation. Descriptive and inferential statistics were utilized for quantitative data analysis. Study findings are presented in tables. Qualitative data was analyzed thematically and presented in form of narratives. Results from the analysis showed that majority of the most common sanitation facility at Mukuru kwa Reuben was container based (51.0%). The socioeconomic factors that significantly influenced the utilization of sanitation facilities by women were cultural beliefs (r=-0.613, p=0.000), that had a strong negative association with utilization, education level (r=0.593, p=0.000), had a strong positive association with utilization, and economic status (r=0.466, p=0.000), had a moderate positive association with utilization. This study highlights persistent challenges in slums, particularly for women's access to sanitation. Socio-economic factors significantly influence sanitation facility utilization by women in Mukuru Kwa Reuben, Kenya. There is need for holistic interventions to address beliefs, education, and economic status for improved sanitation practices.

Behavioural faecal exposure pathways in a nomadic lifestyle :

Batula Jaro Burji — 2024-04-22

Background: Water, sanitation and hygiene (WASH) is the cornerstone for health and growth at all stages of life in maintain health and increase in life span. Poor sanitation has led to disease increase in microorganisms such as Escherichia coli. Sanitation is influenced in a community by factors such as perception, behavioral practices such as open defecation and disposal of these waste. This study aimed to identify behavioral faecal exposure pathways in the nomadic community of Turbi ward.

Methods: Mixed method approach using qualitative and quantitative research methods was applied in this study to assess exposure pathways and related behavior among the nomadic community of Turbi ward. Thematic data analysis was used to analyze data generated from behavioural observations. Data was presented using graphs and pie charts.

Results: A total of 100 households were sampled and about 68% (n=100) of population use surface water for domestic. Turbi manyatta had the highest with 30% (n=100), followed by Kambi Nyoka at 16%(n=100) and the least was Shurr manyatta at 2% (n=100). Surface water was the dominant source of water for these community. About 76% (n=100) of the households did not treat their water before use for domestic purposes and due to scarcity of water the community store water in jerricans for more than one week. About 87% of the residents reported not washing hands before milking animals. Open defecation was the predominant method of waste disposal among the five selected Manyattas, accounting for 95% (n= 100). There was significant relationship between practicing open defecation and using surface water without treatment for domestic purpose at p-value 0.032 (95% CI), using Wilcoxon Signed-Rank test.

Conclusion: The study revealed that the study community’s behavioral practices exposes them to faecal exposure due to habitual practice of open defecation, throwing waste to the bush, open burning, drinking untreated surface water and not washing hands before milking animals. There is need for advocacy on social behavior change, and strategies on health promotion targeting Water, Sanitation and Hygiene (WASH).

Factors affecting financing of communal sanitation facilities by the public sector in Informal Settlements: A case of Nyalenda informal settlement, Kisumu City.

Samuel Atika — 2024-04-22

To close the current sanitation gap, public funding for sanitation has become increasingly insufficient, particularly in Sub-Saharan Africa. What is concerning in Kenya is not the large number of people who lack access to safe sanitation facilities, but the slow rate at which households can gain access to improved sanitation facilities. A sustainable financing strategy is required, one that will increase resource allocations to the sector, improve the efficiency and effectiveness of existing resources wherever they are found, and tap the potential of alternative financing mechanism. A critical review of policy documents like the County Integrated Development Plan (CIDP) shows that there is hardly any documentation on County sanitation plans. Once sanitation lacks in the CIDP, the county can hardly plan for the sector hence making the residents suffer. The study objectives are to examine different sanitation financing options for communal sanitation facilities in Nyalenda informal settlement, to assess factors affecting financing of communal sanitation facilities by public sector in Nyalenda informal settlement and to establish challenges of financing communal sanitation facilities in Nyalenda informal settlement. The study is a descriptive cross-section design. The study used closed and open-ended questionnaires and key informants’ interview in collection of data where n=400. The study established that the dominant communal sanitation financing option in Nyalenda informal settlement was personal contribution (56.0%), followed by NGO financing (40.3%), while the last was County Government financing (0.5%). Public-private partnerships played a crucial role in facilitating sustainable onsite financing for sanitation facilities as evidenced by majority of the respondents agreeing (35.75%). The study recommended the need for diverse financing sources, awareness of available options, and supportive policies to overcome financial challenges.

Jacob Anampiu — 2024-04-22

Introduction: Lack of safe water, poor hygiene, and poor sanitation account for about 90% of the diarrheal diseases in the world. Globally, half a million people lack adequate sanitation, leading to fatalities for over five million people annually. In Kenya, diarrhea still remains one of the top five causes of morbidity and mortality in children below 5 years.

Aim: To identify the household sanitation risk factors contributing to diarrhea in under-five-year-old children in Igembe South Sub County in Meru County, Kenya.

Study Design: A retrospective and cross-sectional study.

Place and Duration of the study: Nyambene Sub-County Hospital, Igembe South Sub-County in Meru County, Kenya between December 2022 and March 2023.

Methodology: The sample size was 196 children calculated from a population of 3,332 children who had diarrhea in Igembe South Sub County out of 22412 children who had diarrhea in Meru County for the last year. Data was analyzed by use of SPSS (2022) and ANOVA.

Results: The study found a strong link (p=0.0034) between diarrhea cases in children under five and the absence of household latrines, as well as sanitation-related factors. It noted that many households lacked proper latrines, and many caregivers did not practice hand washing after handling child feces.

Conclusion: The study identified access to safe drinking water as a key factor in reducing diarrhea in young children. The study recommends close monitoring of sanitation facilities and ongoing assessments of water source safety by the County Government of Meru and other stakeholders to improve overall hygiene and reduce diarrhea cases in the region.

Alex Mutahi Ngatia — 2024-04-22

The safety, health, and dignity of sanitation workers, despite being critical to global sanitation efforts, have long been neglected. This study sought to assess the occupational hazards faced by sanitation workers in informal settlements as well as examining factors associated with the state of occupational safety, health, and dignity of the informal settlement sanitation workers. The study adopted a mixed-methods approach, combining qualitative and quantitative data to provide a holistic understanding of the issues. It employed a case study method to explore the specific challenges faced by sanitation workers in Mukuru slums, considering socioeconomic, environmental, cultural, and policy factors. A sample of 40 sanitation workers was selected for the study based on purposive snowballing technique. Data collection was by use of semi-structured questionnaires, observation, and interviews. The findings revealed significant occupational hazards faced by sanitation workers, including chemical exposure, psychosocial challenges, physical injuries, and biological risks. Socioeconomic factors such as low income and limited education contributed to the workers' vulnerability, while social stigma and discrimination negatively impacted their dignity. Based on the research findings, several recommendations are proposed. These include enhancing training and awareness programs, providing access to personal protective equipment, improving working conditions.

Utilization of Environmental Sanitation Policy Guidelines on the Use of Sanitation Facilities in Public Primary Schools

Beth Wanjiku Njoroge — 2024-04-22

There is a need for a healthy and conducive learning environment, safe drinking water, and child-friendly sanitation facilities in the school where children spend a lot of time. The objectives of the study were to establish the use of existing types of sanitation facilities and find out the status of the existing types of sanitation facilities within primary schools concerning Kenya School Health Policy and the Safety Standards Manual for schools. To achieve its objective, the study adopted a descriptive survey design. A sample of 169 schools was selected from the 773 primary schools in Meru County using simple random sampling. Data was collected using a structured direct observation schedule. Data was analyzed using SPSS software. Descriptive statistics including mean and cross-tabulations were used. The study purposively sampled 167 primary school heads with boys and girls populations of 132,180 and 131,712 respectively. Pearson’s Chi-Square test was used to determine relationships between the variables. The study revealed that 75% of the schools visited kept hygiene and had pit latrines with hand washing stations. Through observation, it was evident that 93% of the schools visited had clean environments that were free from litter. The study concluded that ratios for the sample population fell within the WHO guidelines which recommend a ratio of 25:1 for girls and 50:1 for boys’ toilets. It was concluded that in 46.1 % of the sampled primary schools, pupils living with disabilities experienced challenges in accessing sanitation facilities. The study recommended schools come up with clear budget provisions on sanitation that includes employing a staff specifically for cleaning toilets

The Wildlife-Human Conflicts and Community Perceived Benefits with Proximity to Meru National Park, Kenya

Gervase M'ibui — 2024-04-22

Abstract

Background: Communities and wildlife living in close proximity bear the brunt of direct impacts from human-wildlife conflicts (HWC). HWC can lead to hostility to animal species and loss of livelihoods and spread of infectious diseases. However, few studies have examined HWC and perceived community benefits with proximity to wildlife conservancies. We examined HWC and perceived community benefits of residents bordering Meru National Park, Kenya.

Methods: Data were collected via a structured questionnaire and focused group discussion guide in a cross-sectional study. Ethical clearance was obtained from Meru University of Science and Technology Ethical Review Committee (MIRERC). Authority to carry out interviews was sought from the County Government of Meru. Data were coded and analysed through STATA and summarized using descriptive statistics.

Results: Overall, 96.7 % of the study population were aware of human-wildlife conflict or had experienced it. Elephant, monkey, hyena, lion and the leopard were the frequently reported conflict animals to cause crop damage, loss of livelihood, bodily injuries and destruction of property.

Conclusions

Only 26.6% of respondents were aware of benefits associated with proximity to the park. A multifaceted approach through KWS, community and government urgencies is essential in the management of HWC, to improve corporate responsibilities and minimization of spread of zoonoses.

The logging moratorium in Kenya and its impacts on Community Forests Associations:

Lawrence Mwebia — 2024-04-22

The Forest Sector is Key to Kenya’s social and economic well-being since most of the financial activities rely on environmental-based resources for their sustenance. The Forest Conservation and Management Act, of 2016, provides for the conservation and management of public, community, and private forests. This has brought a paradigm shift in forest management from central command to involving various stakeholders. Adequate stakeholders' engagement in the direction of forest resources, results in minimal conflicts. Local involvement promotes a sense of ownership to the Forest Adjacent Communities Consequently, reducing conflicts in the management of the forest resources. This dissertation focuses on the impacts of logging moratorium on Community Forest Associations in our state forests, with a focus of two CFAs in Meru County. It uses both quantitative and qualitative research design. An in-depth literature review was, used to enrich the research findings. Data was collected from 289 Mucheene and Ruthumbi CFA residents. Their views on the impacts of logging moratorium to the CFA were also documented. The study found out that forest conservation cannot be delinked from livelihood improvement by the Forest Adjacent Communities. There lie difficulties for the area population of the study area to support their life demands with the moratorium in place owing to the fact that they highly depended on the forest to support their livelihoods pre-moratorium. The study found that 93.4 % of the respondents believe that legal logging promotes job creation in the sawmill value chain circular economy. Findings are expected, to inform policy on forest conservation in collaboration with the FAC. The study recommends that the Government should adopt a regulation mechanism that safeguards logging in the extension forest of the community whenever there is an ongoing logging moratorium in the public forest.

The effect of digital marketing on organizational agility of SACCOs in Meru Town

Daniel Kingori Nderitu — 2024-04-22

Savings and Credit Cooperative Organizations (SACCOs) are vital drivers of economic growth in the country. SACCOs provide financial services, including deposits, loans, savings accounts, money transfers, insurance, and payment services. Even though digital media exists to improve the flexibility and the speed of business processes to improve organizational agility, its aspects are a very recent phenomenon among Savings and Credit Cooperative Organizations. An empirical inquiry was relevant to understand the domain of communication, marketing strategies, and its influence on organizational agility since the discourse of digital marketing is continuously developing. SACCOs must understand the association of digital marketing to organizational agility to embrace digital technology in their operations and stay relevant to their members while increasing their level of business resilience. The study sought to determine the effect of digital marketing (social media, mobile, and website marketing) on the organizational agility of SACCOs in Meru Town, Kenya. A descriptive research design was adopted to gather information on the relationship between the two research variables. With a target population of 5 SASRA-licensed SACCOs in Meru Town, data was collected using a semi-structured questionnaire where a stratified sampling method was utilized to attain the desired representation target population of 52 respondents. A pilot test was conducted to check the reliability and validity of the questionnaire adopted as the research instrument. The data was tabulated and analyzed using descriptive and inferential statistics, whereby tabular, graphical, and numerical representations were utilized. Multiple linear regression was conducted to establish the inferential statistics and define the relationship between digital marketing indicators and organizational agility. The study results established that social media marketing, mobile marketing, and website marketing are positively related to the organizational agility of SACCOs. A coefficient of determination (R-squared) of 0.180 indicated that approximately 18% of the variance in organizational agility could be accounted for by the combination of social media, mobile, and website marketing strategies. The moderate level of explanatory power implies that while the chosen predictors are relevant, other factors likely influence SACCOs' organizational agility. The study's outcomes encourage decision-makers to embrace a comprehensive approach that integrates digital strategies into a wider organizational transformation and adaptation framework. The study's findings contribute to the growing body of knowledge regarding the intersection of digital marketing strategies and organizational agility. The study’s results emphasize that the benefits of these strategies extend beyond mere technological implementation, reflecting a fundamental shift in how organizations engage with their ecosystem, respond to changes, and navigate uncertainties.

Nevertheless, the proportion of women with 4^th antenatal care visit and adolescents 10 - 14 years pregnant at the first ANC visit had lower and higher mean scores during the pandemic with significant changes at p=.05 of (p=0.011) and (p=0.003) respectively.

Conclusions: COVID- 19 pandemic did not fundamentally affect MCH services during the first year of the sickness in Meru County. However, the proportion of teenage pregnancies increased significantly, while the proportion of women with 4^th antenatal care visit decreased.

The bioconversion of faecal and kitchen waste using black soldier fly larvae (Hermetia illucens):

Jemimah Sibonje — 2024-04-22

Novel technologies to convert faecal waste into valuable nutrients provide a win-win situation in enhancing the closed sanitation loop, and providing safe sanitation. In this study, laboratory-scale experiments were set to examine the applicability of the Black Soldier Fly in bioconversion of organic matter (faecal matter (FM) and kitchen waste (KW) while producing larvae biomass rich in protein and fat compounds. To determine the mass balance process, each of the feed substrates (500g) in triplicate and 3 grams of 6-day-old larvae (844 larvae) were introduced. The larval developmental time to 50% pupation, survival rate (SR), waste reduction rates (WR), prepupal yield, bioconversion rate (BCR), feed conversion rate (FCR), and efficiency of digested feed (ECD) were monitored in triplicate at the end of the experiments for mass balance process. Mass balance determination (triplicate) yielded average prepupal yield of 70.43±0.02g and 56.77±0.01g, with protein content per unit ranging from 32.23% to 41.26% and 20.06% to 37.13% on faecal and kitchen waste respectively. The ECD of 17.63±0.01% and 12.05±0.00%, waste reduction of 79.91% and 92.24% from faecal and kitchen waste respectively were obtained. From the findings, both substrates were palatable as BSFL feeds. The study findings show the potential of using BSF larvae technology to valorise faecal and kitchen waste and produce larval biomass rich in proteins and fats.

Pathogen inactivation from faecal waste via black soldier fly treatment

Alice Mumali — 2024-04-22

Sustainable development goal 6.2 advocates for increasing access to equitable and adequate hygiene and sanitation for all by 2030, and its indicator target is to raise the proportion of the population using safely managed sanitation. On the contrary, it is approximated that only 54% of people globally have access to safely managed sanitation, while 2.4 billion lack access. Recent innovations have however seen the development of low-cost technologies that can be customized depending on the region. The container based sanitation (CBS) is one of the options for safely managing the waste compared to conventional sewerage systems that are expensive. However, the need for emptying and transportation of filled fecal sludge (FS) containers on daily basis, leads to high operational costs and increases the operational exposures risks to fecal pathogens amongst the CBS operators. The study determined the performance efficiency of Black Soldier Fly Larvae in inactivation of E.coli via seeded container based sanitation- Urine diverting dry toilet model. Sample was transported to the lab for analysis of E.coli after every 3 days from Seeded households and samples from Non seeded households in replication. One gram of sample was used in serial dilution up to factor 5.The inoculum was plated in Tryptone Bile Glucuronic (TBX) agar for enumeration according to manufacturer’s instructions. Plates with 30-300 colonies were considered viable for counting. The study used statistical analysis IBM SPSS software from the sets of experiments. The E.coli (CFU/ml) mean varied between 7.3±1.3 and 10.1±2.8 for Seeded treatments while non-seed treatments ranged between 7.5±1.6 and 10.4±3.2. A significant variation occurred between the two treatments at p<0.05(SH and NH). Findings from this study showed that there was reduction of E.coli coliforms with Bioconversion of organic waste using the BSF technology has been noted to reduce the E.coli load and reducing the volume of the bio-waste. Sanitation policy makers can apply the findings of this study in formulation of policies on safe handling and disposal of fecal matter from onsite sanitation facilities.

Comparative awareness on zoonoses between residents at the Human-wildlife Interface Zone and inhabitants of the non-wildlife areas of Meru County, Kenya

Gervase M'ibui — 2024-04-22

Abstract

Introduction: Zoonoses are infections transmitted from vertebrate animals to humans. Persons with low knowledge, exposure to wildlife or domestic animals are at risk of zoonoses. Research, surveillance and response through One Health framework is necessary for prevention. We compared the knowledge on zoonoses between residents at the wildlife-interface of Meru National Park, and non-wildlife areas of Tigania West Sub County, Meru Kenya.

Methods: Data were simultaneously collected using a structured questionnaire in both zones and compared. Descriptive statistics were used to summarize the data for differences between variables in the two areas.
Results: The non-wildlife zone residents of Tigania West Sub-County had statistically significantly better knowledge of zoonoses than their counterparts next to Meru National Park: χ² (1, N=525) =84.965, p< .001.

Conclusion: The scanty knowledge on zoonoses of residents of Igembe Central posed greater risk of zoonoses because their proximity to the wildlife conservancy. Awareness creation through one health strategy is necessary as a deterrent measure.

Inhibition of Ralstonia solanacearum by Warburgia ugandensis stem bark and leaf crude extracts obtained using organic solvents

Oliver Libese Lideke — 2024-04-22

Ralstonia solanacearum is a soil-borne bacterial pathogen that poses significant threat to the Solanaceae family and other crops. It causes widespread bacterial wilt, a devastating disease that affects the plant's water transport system, leading to wilting and death. Numerous chemical agents and treatment methods have been employed in attempts to control R. solanacearum, but are ineffective. The study aimed to determine the in vitro efficacy of W. ugandensis stem bark and leaf crude extracts against R. solanacearum. W. ugandensis stem bark and leaf crude extracts were obtained using organic solvents viz. methanol, ethanol, dichloromethane and hexane. In vitro, antagonistic activities against R. solanacearum of all organic crude extracts of W. ugandensis were determined by standard agar well diffusion assay on Kelman’s 2, 3, 5- triphenyl tetrazolium chloride medium in triplicates. Two-way analysis of variance (ANOVA) was used in the statistical analysis of the mean diameter inhibition zones. All the organic solvents crude extracts of W. ugandensis were inhibitive against R. solanacearum. However, the stem bark crude extracts exhibited significantly higher efficacy against R. solanacearum compared to the leaf crude extracts. The crude extracts were subjected to a serial dilution to determine the minimum inhibitory concentration (MIC). W. ugandensis stem bark dichloromethane crude extracts had the lowest MIC of 1 mg/ml. W. ugandensis stem bark dichloromethane crude extracts were most effective against R. solanacearum. Further research is important to determine the bioactive compounds against R. solanacearum in W. ugandensis stem bark dichloromethane crude extracts.

Effects of concentrate supplementation on lactating Dromedary Camels during mating season in Isiolo, Kenya

Florence Thiakunu — 2024-04-22

Camels are resilient and have a high potential to contribute to food security and economic development in arid areas. However, this potential is being limited by diminishing feed resources due to the effects of climate change. Further, there is an upcoming peri-urban camel production system where the animals are limited in their movement. Consequently, camels do not get enough browse forages in terms of biomass and quality to meet their nutritional requirement. This has resulted in decreased production and reproductive performance. The objective of this study was to determine the effect of concentrate supplementation on lactating camels on productive and reproductive performance during mating season. A diet containing 16.80% crude protein (CP) and a digestible energy of 8.44 MJ/Kg was formulated and supplemented in the evenings with a group of ten camels. Another group of 10 camels acted as the control. Milking was done in the morning and production from each camel was recorded in liters. Percentage milk fat and protein analysis were done weekly using Gerber and Kjeldahl methods respectively. Serum biochemical levels were determined using spectrophotometry in the fourth week. Confirmation of pregnancy was done on the 5^th month after mating by chemiluminescent progesterone assay. Camels were then divided into four groups. These were, supplemented pregnant(4) supplemented and not pregnant(6) un-supplemented pregnant(1), and un-supplemented and not pregnant(9). Paired mean comparisons were done to ascertain differences within the four groups. Mean daily milk production was 25.26±0.42 and 22.79±0.41 liters for supplemented and un-supplemented groups respectively (p<0.001). Paired mean differences were highest between pregnant supplemented and pregnant un-supplemented pair (p=0.165). Biochemical profiles, mean milk protein and fat percentages were significantly higher for supplemented than un-supplemented (p˂0.05). All supplemented camels were mated within the first two weeks and had a higher conception rate (40%) than un-supplemented (10%). The study recommends concentrate supplementation during mating season to improve fertility and milk production, especially in pregnant camels.

A Health-Related Quality of Life: differences between Human-Wildlife Interface and Non- Wildlife Zones of Meru County, Kenya

Gervase M'ibui — 2024-04-22

Background: Emerging infectious diseases (EIDs) of animal origin are increasing. Research, collaboration and surveillance on population health as per the WHO definition of health through one health is necessary to prevent these zoonoses. Comparison of Health Related Quality of Life (HRQoL) between residents at the human-wildlife interfaces and non-wildlife zones can identitify health inequalities for action. We compared the HRQoL of such areas in Meru County, Kenya.

Methods: Data were simultaneously collected using the European Quality of Life Five Dimension, Five Level questionnaire (EQ-5D-5L) in Igembe Central and Tigania West Sub-counties. Associations between the HRQoL variables and the hypothesis were tested through chi statistic and odds ratio respectively.

Results: Participants largely reported no problems in the dimensions of EQ-5D-5L. However, the HRQoL significantly differed between the two populations. Populations at the brink of Meru National Park reported more problems in the worry (anxiety/depression) dimension of the EQ-5D-5L than their counterparts in Tigania West.

Conclusions: Further studies are required to address the cause of anxiety/depression to improve population mental health around the Park.

Errors, error detection and correction efficiency in the container number code

Mutugi Praise Kiogora — 2024-04-22

The container number is an 11-digit code that uses a single parity check of modulo 11 to check the authenticity of the container numbers. The world relies on shipment containers to transport goods. Various types of cargos have been erroneously delivered in different places. The modulo 11 container number is divided into four parts. The owner code that consists of three capital letters of the Latin alphabet to indicate the owner or principal operator of the container. Such code needs to be registered at the Bureau International des Conteneurs in Paris to ensure uniqueness worldwide (per ISO 6346). The equipment category identifier consists of one of the following three capital letters of the Latin alphabet U for all freight containers, J for detachable freight container-related equipment, Z for trailers and chassis. The serial number consists of six numeric digits, assigned by the owner or operator, uniquely identifying the container within that owner/operator’s fleet. The check digit consists of one numeric digit providing a means of validating the recording and transmission accuracies of the owner code and serial number. The objective of this study is to determine the efficiency of the current modulo 11 container number in the error detection and correction. While the modulo 11 checksum calculation method is an effective way to detect errors in container numbers, it is not foolproof and errors can still occur. Modulo 11 container number code does not detect some transposition and substitution errors. The container number code and its check digit do not possess inherent error correction capabilities. This study therefore recommends a new modulo 13 container number code with higher error correction and detection capability.
