    EMPIRICAL ANALYSIS OF ADMINISTRATIVE ENGAGEMENTS IN RELATION TO EMPLOYEE PERFORMANCE IN POLYTECHNICS: EVIDENCE FROM KWARA STATE, NIGERIA
    (International Journal of Global Affairs, Research and Development (IJGARD),, 0026) 1 Idowu ,H. A. O.; 1 Kadiri A.T; 2Abraham, M. M
    This study examined the relationship between administrative engagement and employee performance in selected Polytechnics of Kwara State, Nigeria. The research was motivated by concerns over declining staff commitment, weak administrative practices, and inadequate employee engagement in public tertiary institutions. A descriptive survey research design was adopted with a quantitative approach. The population comprised 3,983 academic and non academic staff from Federal Polytechnic Offa, Kwara State Polytechnic Ilorin, and Lens Polytechnic Offa. Using the Taro Yamane formula, a sample size of 363 respondents was utilized with 314 valid questionnaires analyzed. Data were collected using a structured five-point Likert scale questionnaire. Descriptive statistics and Structural Equation Modelling (SEM) using Smart PLS 4 were employed at a 0.05 significance level. Results revealed that administrative engagement significantly and positively influences employee performance (β = 0.536, t = 12.993, p = 0.000), explaining 28.7% of performance variance (R² = 0.287) with a large effect size (f² = 0.403). The study concluded that effective administrative communication, recognition of ethical conducts, transparent leadership, and staff involvement in decision-making largely enhance employee commitment and productivity. It recommended, among others, that constituted authorities should endeavor to strengthen internal communication systems, establish formal recognition programs, encourage and promote participatory decision-making, and map out ethical leadership training for administrators.

    Design and Implementation of an AT89C52 Microcontroller Based Water Pump Controller
    (International Journal of Innovative Science, Engineering & Technology, 2016-07-07) Kehinde, Olufemi O; Bamigboye, Oladayo O.; Ehiagwina, Fredrick O.
    serious problem faced by several cities of the World, with wastage during pumping and distribution identified as a culprit. This paper developed a microcontroller based water pump controller aimed reducing water wastages and pump failures, due to not switching it off immediately when not needed. The control system from which water level of both tanks are observed with simultaneous water pump control is based on existing water level technology using the principle of ultrasound for level sensing. A prototype of the proposed microcontroller based water pump controller was fabricated and tested. This paper provided an improvement on existing water level controllers by its use of calibrated circuit to indicate the water level and use of DC instead of ac power, thereby eliminating risk of electrocution. The developed system is capable of powering a 1HP pump from the input voltage, which can deliver an output current up to 20A. The system will help to eliminate the cost and inefficiency of human interference associated with manual monitoring and controlling of pump, while maximizing the performance and life span of the electric water pump
