The burden is disproportionately borne by pedestrians, cyclists and motorcyclists, in particular those living in developing countries. Kenya, as a country has made little efforts in ensuring safety for all road users at all times. The objective of this study was to assess the patterns and mortality rates of motorcycle related injuries in Kerugoya town, Kirinyaga County. A retrospective cross- sectional study design was employed. Secondary data on motorcycle related accidents was collected and analysed for 385 victims. Data was collected using structured checklists. The process involved one-year review of existing records from Kerugoya Referral Hospital and the County Traffic Police Department. Data analysis was done using Statistical Package for Social Sciences (SPSS) version 20. The mean age of motorcycle crash victims was 31.5 years (range 7-60years). Males were 228(62.1%) and females 139(39.7%). The most common pattern (anatomical part) of injury sustained by victims was lower extremity injuries 124(34.0%), followed by head and neck injuries 107 (29.1%), chest injuries 74(20.1%) and upper extremity injuries 62(17.0). Majority of motorcycle riders 62 (32.6%) and passengers 58 (30.5%) who did not have a helmet during the time of crash sustained head and neck injuries. Passengers (65%) constituted a larger percentage of the crash injury victims reporting to hospital. We recommend that County traffic department should organize consistent public awareness education on road safety. 2023-05-01T00:00:00Z http://hdl.handle.net/123456789/853 Internal Control Measures On Fraud Detection and Prevention in Fintech Companies in Kenya Wanyama, D ,N; Mwikya, J. The study sought to examine the effect of internal controls on fraud detection and prevention among Financial Technology (FINTECH) Companies in Kenya, case of Interswitch (Kenya) Limited. The study adopted three major objectives; to establish the impact of know your customer practices on fraud detection and prevention, to examine the effects of information technology on fraud detection and prevention and to determine the impact of staff training on fraud detection and prevention. The target population of 200 and a sample size of 100 people, this study employed primary data collected through questionnaires. The study adopted a descriptive survey research design, the decision to apply descriptive cross-sectional survey research design. The study results showed R = 0.734 that means there was strong and positive relationship between the study’s internal control measures and fraud detection and prevention. Further the regression shows an overall R2 = 0.539 meaning that 53.9% of the measures of detection and prevention of fraud in financial technologies companies in Kenya is explained by the three independent variables namely information technology, know your customer and staff training. Study conclusions are; through reliable information technology, company management will be able to take strategic decisions for the future of the company, especially in detection and prevention fraud. The use of CAATs or e-audit systems is able to overcome fraud risk and this is believed to be able to detect the possibility of fraud that may occur. Know your customer check should be a mandatory process of identifying and verifying the client's identity when opening an account and periodically over time. In order to detect and prevent fraud, employees must first know what to look for, and then what to do about it. Finally the internal control measure’s has an influence on detection and prevention fraud. 2022-06-01T00:00:00Z http://hdl.handle.net/123456789/750 FBG Hydrogen Sensor Based on Pd87–Ni13/Pd4–Ag1 Thin Film and Femtosecond Laser Ablation Zhou, X., Karanja, J. M., Yang, M., Zhou, F., Liu, K., Ming, X., & Dai, Y A novel laser machined spiral microstructure fiber Bragg grating (FBG) hydrogen sensor and coated with composite sensing film is presented. The sensor probes are sputtered with Pd/Ni and Pd/Ag film, respectively. Experimental results exhibit that a pitch 60 μm FBG with double spiral microstructures, coated with 520 nm Pd/Ni and Pd/Ag film has hydrogen gas sensitivity in air of 13 pm/%H and 25 pm/%H, respectively. The laser-ablated spiral microstructured probes with composite films shown greater sensitivity compared with standard FBG probes with similar coating. The optimum testing temperature (50 °C) enhanced the sensitivity and repeatability of the probes. 2021-12-01T00:00:00Z
