    Awareness of Antenatal Services and Health Seeking Behaviour among Pregnant Women in Osun State
    (International Journal of Research and Scientific Innovation, 2025) Adejumo Bosede Oluwatosin
    Antenatal care (ANC) plays a crucial role in ensuring maternal and fetal well-being, yet awareness and utilization of these services vary across different populations. This study examined the awareness of antenatal services and health-seeking behaviour among pregnant women in Osun State, Nigeria. A cross-sectional survey was conducted among pregnant women in Osun State, using a well-structured 82-item questionnaire to assess their awareness, health-seeking behaviour, attitude towards their health and influencing factors for their utilization. Three hundred and twenty-two (322) pregnant women participated in the study and were selected using simple random sampling technique across 8 of the 30 local government areas in Osun State regardless of their age and marital status. Data were analyzed using Statistical Package for Social Science (SPSS) version 23.0. The findings of this study revealed that most (57.1%) of the respondents were aware of antenatal services, have a fairly good (57.8%) health-seeking behaviour, but poor (53.4%) attitude towards their health. This study also revealed that there was a statistically significant association between sociodemographic variables, age, education level and income, and health-seeking behaviour of pregnant women in Osun State at p less than 0.001; and that there was no statistical significant association between age and education level, and attitude of pregnant women in Osun State at p greater than 0.05, however, there was a statistically significant association between income and attitude of pregnant women in Osun State at p value 0.045. The study highlights the 9need for targeted health education programmes, improved healthcare accessibility, and community-based interventions to enhance ANC utilization. Strengthening maternal healthcare policies and addressing socioeconomic barriers can contribute to better maternal and neonatal outcomes.

    Effect of Pit Sand on Compressive Strength of Coconut Shell Concrete
    (Journal of Engineering and Architecture, 2015) Oyedepo Olugbenga Joseph
    The high and rising cost of building materials is one of the major factors affecting housing delivery in Nigeria. Therefore, there is the need to reduce the cost of building construction either through effective construction management or usage of alternative available local materials. Concrete is one of the most important building materials in Nigeria presently, however, one of its major disadvantage, is its high selfweight compared to other construction materials. Hence research focused towards producing a lightweight concrete from locally available material, which will reduce the total self-weight of the structure, with corresponding reduction in cost is of national interest. This work investigated the effect of pit sand on the mechanical properties of concrete produced using coconuts hells as a replacement for coarse aggregate. Two batches of concrete mix were produced using coconuts hells as aggregate, with mix ratios 1:2:4. One of the batches was produced using unwashed sand from borrowed pit, while the second batch was produced using washed sand respectively. From each batch of concrete mix, 20 concrete cubes of size 150 mm x 150 mm x 150mm were produced and cured by immersion in water in curing tanks. Cubes produced using unwashed sand were named specimen A, while that produced from washed sand were named specimen B. The research shows that there is increase in the compressive strength of concrete produced from washed sand over that produced using unwashed sand. Also, concrete produced by 25% partial replacement of crushed granite by coconut shell using unwashed sand and 25% to 75% partial replacement for washed sand, can be used for structural purposes.

    EVALUATING PERFORMANCES OF TRAFFIC NOISE MODELS
    (Nigerian Journal of Technology, 2014) Oyedepo Olugbenga Joseph
    Traffic noise in decibel dB(A) were measured at six locations using 407780A integrating sound level meter; while spot speed and traffic volume were collected with cine-camera. The predicted sound exposure level (SEL) was evaluated using Burgess, British and FWHA model. The average noise level obtained are 77.64 dB(A), 72.95 dB(A) and 75 dB(A) respectively. The values from Burgess and FWHA model lies within an error band of ±5% with reference to the observed noise levels. Thus, the three models are effective in predicting equivalent traffic noise index in Akure with fair accuracy. The coefficient of correlation (R2) between the observed sound exposure level and predicted sound level are 0.931 and 0.968 respectively; thus, there is a good correlation between the observed and the predicted value. Adequate road design and management of traffic flow are recommended to reduce road traffic noise in the study area.

    Evaluating Vehicular Delay Cost of Congested Road Networks in Akure Ondo State, Nigeria
    (Journal of Applied Science & Process Engineering, 2016) Oyedepo Olugbenga Joseph
    Estimate of the impact of congestion such as economic and productivity loss was evaluated along three selected routes namely RA, RB and RC in Akure using cost and delay. Travel speed, and Average Daily Traffic (ADT) were measured using cine camera; while fuel consumption was measured per litre using the vehicles fuel gauge. The annual person hours of delay (APHD) of 626.25 hrs, 918.51 hrs and 140.91 hrs was obtained for route A, B and C respectively. The daily wasted fuel cost for vehicle on RA, RB and RC are N785.83/day, N 959.9/day and N 130.5/day respectively, while N6,506.42/ day, N 7,676.63 and N 2,110.92 was obtained for total delay cost (TDC) on the RA, RB and RC. Also, fuel wasted associated with congestion for RA, RB and RC are 1,642,352.40 naira per year, 1,937,735.8 naira per year, and 532,838.80 naira per year respectively; this amount to economic loss. Provision of effective public transit, efficient off-street parking system, and enforcement of traffic rule and regulation were recommended as a panacea to traffic congestion problem in the study area.

    Evaluation of Bitumen-PET content in Asphalt for Road Construction
    (International Journal of Academic and Applied Research, 2025) Oyedepo Olugbenga Joseph
    The incorporation of waste plastics such as polyethylene terephthalate (PET) into asphalt binders presents a sustainable approach to enhance pavement performance while addressing environmental concerns. This study aims to evaluate PET-modified bitumen content for road construction applications. PET in form of plastic bottles ground into powder form was added to bitumen in varying percentages (2%, 4%, 6%, 8% and 10%) by weight of the bitumen. Both the control and modified bitumen were then subjected to standard tests such as penetration, ductility, softening point, viscosity, flash and fire point and loss on heating to determine their properties. The optimum PET content was then evaluated as 8% by weight of the bitumen which corresponded to the maximum penetration index value and was used to prepare the asphalt concrete in which the bitumen+PET content was varied in percentages of 5%, 6%, 7% and 8% by weight of the asphalt. The Marshall stability and flow, percent air voids, bulk density, voids in mineral aggregate (VMA) and voids filled with bitumen (VFB) of the asphalt concrete samples were determined and used to evaluate the optimum bitumen+PET content as 5.9% by weight of asphalt which can be used to produce high performance asphalt pavement.
