Abstract:

This study which is a prospective cross-sectional survey ascertained the distribution of bacterial and fungal external eye infections among children attending the Federal University Teaching Hospital, Owerri, Imo State, Southeast Nigeria. Owerri comprises Owerri Municipal, Owerri West and Owerri North Local Government Areas. The sample population was 460 subjects, aged 1-17years. Ocular samples were collected with sterile swabs from infected eyes for culture and identification to ascertain the type of infection, weather bacterial or fungal. Data were analysed with chi-square, analysis of variance (ANOVA), correlation test and simple percentage using statistical package for social sciences (SPSS) version 20.1 ((P-value ≤0.05). The most occurring eye infection was bacterial conjunctivitis (74.6%), followed by blepharitis (11.3%), bacterial keratitis (5%), hordeolum (3.9%), lid abscess (2.2%) and dacryocystitis (1.7%). Fungal keratitis (1.3%) was the least and only fungal external eye infection seen. Bacteria were found to be the major cause of conjunctival and corneal infections in the eye (86.09%). Bacterial conjunctivitis was most recorded among the 1-3 age group (93.1%), followed by 4-7 age group (80.6%), 8-11 age group (70.6%), 12-14 age group (65%) and 15-17 age group (48.7%). It occurred highest among the males (77.6%) than the females (71.4%). Fungal keratitis was recorded highest (5.1%) among the 15-17 age group followed by 12-14 age group (2.5%), while no case was seen among the other age groups. Owerri West recorded the highest bacterial and fungal external eye infections (43.26%), followed by Owerri North (35.86%) and Owerri Municipal (20.9%). Generally, there was higher rate of external eye infection among the males (50.65%) than females (49.34%). Key words: External eye infection, Conjunctivitis, Children, Age, Sex, Residential area.

Abstract:

In this research, measured meteorological data, empirical models were used to estimate the global solar radiation in Owerri, Nigeria. The global solar radiation data was correlated with the relative sunlight duration, relative humidity, and maximum temperature for Owerri, Nigeria, using Angstrom and Page's linear regression model. Additional multiple linear regression models were produced to examine the relationship between the amount of solar energy received worldwide and other climatic factors, such as the maximum temperature and relative humidity. The Nigerian climatic Agency (NIMET) in Abuja provided the climatic characteristics for this study for the 11-year period between 2011 and 2021. Four statistical error indicators—Mean Bias Error (MBE), Root Mean Square Error (RMSE), Mean Percentage Error (MPE), and t-stat—were used to verify the data' statistical validity. Although certain models correlate more strongly than others, the results demonstrate a strong relationship between the predicted mean worldwide solar radiation and the measured mean global solar radiation using the established models. Based on the t-statistic results, the optimum empirical equation for city was assessed. The best model for Owerri is 𝐻2 = 𝐻𝑂 (−0.496 +0.599 (𝑛𝑁) +0.025(𝑇𝑚𝑎𝑥)) with t – stat value of 0.79. The global solar radiation intensity obtained with these models can be used in the design, analysis and performance estimation of solar energy conversion systems which is gradually but steadily gaining ground in Nigeria and the world at large. Keywords: Solar Radiation, Empirical model, Temperature, relative humidity, sunshine hour, Owerri.

Abstract:

Background: Ofe-Owerri is an expensive traditional soup in Nigeria, prepared using Oha (Pterocarpus soyauxi), Ukazi (Gnetum africanum), Uziza (Piper guineense) and cocoyam (Colocasia esculanta) as the major vegetables. The soup is highly celebrated for its traditional therapeutic and nutritional potentials. Objective: In this study, we assessed the proximate and mineral components, sensory and microbial qualities of the Ofe-Owerri soup in a cooked and packaged form. Antioxidant status and phytoconstituents of the major vegetables of the soup were also determined. Methods: Established methods were used as previously reported in the literature. Results: Calcium was the most concentrated mineral, whereas lead was absent. High moisture (63.45%), crude protein (14.60%) and fat (13.27%) were found in the soup. The major ingredients (vegetables) used to prepare Ofe-Owerri contain phytochemicals such as phenolic compounds and saponins, and showed potent antioxidant activity in various in vitro models, with uziza displaying the highest scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical. The vegetables exhibit reductive capacity against oxidants, and chelation of metallic free radicals. There was no significant difference (p≤0.05) in the sensory parameters of Ofe-Owerri soup kept frozen in foil and plastic containers, respectively, for 21 days. Conclusion: This study showed that Ofe-Owerri is a good dietary source of nutrients and possesses phytoconstituents with potential beneficial health effects. When properly packaged, the soup can be stored safely for up to three weeks.

Abstract:

ABSTRACTIn September 1996 the city of Owerri in south-eastern Nigeria erupted in riots over popular suspicion that the town'snouveaux richeswere responsible for a spate of ritual murders allegedly committed in the pursuit of ‘fast wealth’. In addition to destroying the properties of the purported perpetrators, the rioters burned several pentecostal churches. This article examines the place of religion in the Owerri crisis, particularly the central position of pentecostal Christianity in popular interpretations of the riots. While pentecostalism itself fuelled local interpretations that ‘fast wealth’ and inequality were the product of satanic rituals, popular rumours simultaneously accused some pentecostal churches of participating in the very occult practices that created instant prosperity and tremendous inequality. The analysis explores the complex and contradictory place of pentecostalism in the Owerri crisis, looking at the problematic relationship of pentecostalism to structures of inequality rooted in patron-clientism and focusing on the ways in which disparities in wealth and power in Nigeria are interpreted and negotiated through idioms of the supernatural.

Abstract:

The study is basically to examine electronic-voting in Nigeria elections as an improvement on the traditional paper voting with a focus on Owerri Senatorial Zone, Imo State. Worried by the frequent and debilitating incidences of electoral fraud and disenfranchisement of voters for unsubstantiated reasons, the study tended to sample opinion of respondents in Owerri on the subject as a way of strengthening democracy. Martin Hagen theory of e-democracy was adopted as theoretical framework. Hagen construes e-democracy as a strategic tool to strengthen democratic practices using the information and computer technology (ICT). The study is a survey attempt which made use of structured questionnaire to elicit information from respondents. Simple per centage was used for data analysis. It is our finding among others that e-voting will reduce incidences of election fraud especially in the areas of voting and counting of votes, and also the physically challenged qualified voters and citizens living and working abroad will have opportunity to cast their votes. The study concludes that Nigeria must cash in on flourishing (ICT) to fight endemic electoral irregularities in Nigeria through firm belief in and avowed adoption of e-voting. The study recommended among others institutionalization of legal frameworks and structures that will formidably support the practice of e-voting in Owerri senatorial zone in particular and Nigeria in general.

Abstract:

Most, if not all, of the estates in Owerri, Nigeria are planned without recourse to the United Nations Sustainable Development Goals (SDG) envisions 2030’s goals 7 and 11. SDG goal 7 (on affordable and clean energy) and goal 11 (on sustainable cities and communities) envision a world by 2030 where there will be universal access to affordable, reliable, and modern energy services; a substantial increase in the share of renewable energy in the global energy mix, etc. This research was done to depict the feasibility of a photovoltaic (PV) power plant for estates in Owerri, Nigeria. A standalone PV solar power plant for a typical 200 bungalow housing estate in Owerri, Nigeria was designed and simulated to study its techno-economic feasibility using PVsyst 7.3 simulation software. The study revealed that with a global horizontal irradiation of 4.70 kWh/m2/day reaching Owerri, Nigeria, a 468 kWp PV system is required to supply the electricity needs of an estate with an energy demand of 1,480 kWh/day. The system will generate a total of 615,168 kWh of electric energy in a year with a performance ratio of 70.4 % and a solar fraction of 96.8%. The designed PV solar power plant is highly feasible as the obtained results from the economic simulation showed that the system’s installation cost is 466,970 USD at a specific cost of 1.0 USD/kWp, and the net present value (NPV) is positive at 842,699.16 USD, 752,219.11 USD, and 698,107.07 USD, respectively for the 0%, 50%, and 80% loan financing cases. With an energy tariff of 0.15 USD/kWh, the return on investment, payback period, and levelized cost of energy were determined as 180.5%, 7.2 years, and 0.0698 USD/kWh, respectively for the 0% loan financing case.

Abstract:

The study basically concerns itself with child care services adopted by career mothers in banks with children (0-5) yrs in Owerri Municipality. Four research objectives guided the study and a structured questionnaire was used to elicit data from the respondents which consist of career mothers working in the various 30 banks in the study area, while data collected were analysed using Tables and mean scores calculated. Based on the findings of this study, the researchers reached the conclusions that career mothers in banks have various ways of taking care of their children (0-5)yrs in Owerri Municipality and encounter a range of challenges including mother’s difficulty to understand who the children are, children refuse to obey mothers when mothers are available, mothers lose grip on their children in terms of respect, tiredness makes mothers adopt permissive parenting, children make extra demands of attention when mothers are available, are encountered by career mothers in banks in bringing up their children (0-5yrs) in Owerri Municipality. Despite the challenges, there are possible strategies adopted by career mothers in banks to help them cope with these challenges in Owerri Municipality which are; career mothers in banks should spend extra time with their children, consider adopting punitive measures in parenting, as well as, motivation and family incentives. Career mothers should also share appropriately their time between work-life balances.

Abstract:

This study assessed the antibiogram and bacteriological assessment of raw meat sold in Owerri. Samples of fresh beef were taken from beef vendors from three (3) markets; Relief market, Ekeonuwa market and Amakohia market in Owerri, Imo State. Three samples each weighing 100g were aseptically collected in sterile polythene pouches, sealed and transported in ice to the Imo State University Microbiological Laboratory for microbiologic alanalysis within some few hours of collection. The results of this study showed that the total heterotropic bacteria counts of ranged from 3.72× 105cfu/g - 4.2 × 105cfu/g , the coliform bacterial counts ranged from 1.9 × 105cfu/g - 2.7 × 105cfu/g while the total salmonella shigella count ranged from 0cfu/g -4.12x103cfu/g. Bacteria isolated were Escherichia coli, Salmonella spp., Streptococcus spp., Bacillus spp. and Staphylococcus aureus. Of the 50 bacterial isolates obtained, E. coli [15 (27.7)] and Staphylococcus spp [15 (27.7)] were the prevalent isolates. Other bacterial pathogens incriminated in this study were Salmonella spp [9(18.0)], Bacillus spp [7(14.0), and Streptococus spp [4 (8.0)].Most of the Gram-positive bacteria were highly susceptible to ceftizoxime and the Gram-negative to gentamicin and cefotaxime. E. coli, was susceptible to ampicillin/sulbactam (71% susceptibility), cefotaxime (71%), ciprofloxacin (94%), chloramphenicol (94%), ceftizoxime (100%), ofloxacin (82%), and amikacin (100%). S. aureus was susceptible to ampicillin/sulbactam (75%), cephalexin (75%), cefotaxime (100%), roxithromycin (75%), lincomycin (75%), and gentamicin (100%). Bacterial quality of fresh beef sold in Owerri has shown that beef sold in Owerri is contaminated with Staphylococcus spp., Escherichia coli and Salmonella spp. but the prevalence of Salmonella spp. was low.This findings shall guide clinicians in the management of food poisoning/enteritis from possible meat consumption. Effective supervision and health education of meat sellers and their abbatoirs is highly recommended.

Abstract:

It is impossible to overstate the importance of propagation models in wireless network planning, frequency assignment, and television parameter evaluation. The fact that no two locations are identical in terms of climatic conditions, building patterns, terrain, etc. makes using path loss predicting models for any area extremely challenging. Therefore, it is impossible to develop a single path loss model that applies to all environmental settings. The main aim of this study is to develop a path loss model for NTA channel 12 Owerri and evaluate its performance based on received signal strength values along five selected routes in Imo State, Nigeria.A suitable path loss model was developed by critically analyzing the measured path loss values of each base station, which were retrieved from the signal strength data received. The values of the developed path loss model were compared to those of other empirical path loss models developed by other researchers as well as the measured path loss values. The results show that the proposed path loss model is well suited for predicting the path loss of NTA channel 12 Owerri signals in the study environment, while the other conventional empirical models taken into consideration in this study overestimated the path loss of NTA channel 12 Owerri signals with Root Mean Square Error and Mean Error of 63.65 and above. Additionally, the findings indicate that NTA Owerri performs poorly at a distance of 18 kilometers from the base transmitting station. The overall findings are helpful for designing prospective television network channels in the study location and other similar environments.

Abstract:

Background: Global understanding of surgical outcome is still limited, with data lacking in some areas of the world. Global studies most times are dominated by data sourced from high income and developed countries. Aim: This study is aimed at evaluating the differential surgical outcomes in a Health Institution in Nigeria, to help understand how patients develop postoperative complications and the severity of such complications. Methods: We recruited 200 patients that were booked for elective or emergency in-hospital or day case surgery. The patients were followed up for maximum of 30 days postoperatively. Perioperative outcomes were evaluated. Results: The majority of the participants were in ASA II class (46%), while the others were in class ASA III (31%), ASA I (20%) and ASA IV (3%). There were 35% participants that had intraoperative complication, while 29% had postoperative complication. The rate of ICU admission was 5%, while the duration of postoperative ICU and hospital stay were 1.7±0.90 days and 13.28±2.97 days respectively. Surgical related mortality rate was 3%. Conclusion: The findings show that despite the high intraoperative complication rate of 35%, postoperative complication rate of 29% and critical care admission rate of 5%, mortality rate (3%) was the same with other global studies.

Abstract:

A good road network consists of a constant stretch of asphalt laid down for a smooth ride. The spot in the smooth ride on the pavement is commonly referred to as "pavement failure." Soil type, load bearing capacity of materials, zone of vulnerability, resistance to permeation, compressibility, shrinkage limit, and other details are frequently required in order to construct a very good and solid foundation for the planned bridge site. In Nigeria, numerous factors contribute to the failure of road construction projects. They are primarily insufficient research on subgrade and other pavement materials (sub-base and base courses) prior to the start of road projects; flawed engineering, including a poor drainage system and supervision throughout road construction; and shoddy workmanship that was superimposed with asphaltic concrete to improve strength. Within the Niger Delta basin, the study area is located between latitude 5.485°N and longitude 7.035°E. The Benin Formation underpins the study area. It is composed primarily of friable sands, conglomerates, very coarse sandstone, and isolated gravel units, as well as intercalation of Pliocene to Miocene shale/clay lenses. Natural Moisture Content (NMC), Linear Shrinkage (LS), Particle Size Distribution, and California Bearing Ratio were among the laboratory tests performed on samples collected at failed and stable sections of some selected road segments (CBR). When compared to the stable sections, the NMC along the failed sections was on the high side (ranging from 13.11 percent to 26.89 percent) (ranging from 11.11 percent to 16.40 percent). The majority of the tested soils passed the 0.075mm sieve with a percentage greater than the Federal Ministry of Works and Housing's maximum of 35% for subgrade materials. The maximum dry density (MDD) for the samples at failed and stable sections was 1550 kg/m3 to 1860 kg/m3; 1650 kg/m3 to 1980 kg/m3; and the Optimum Moisture Content (OMC) was 8.30% to 20.30%. The soaked CBR values ranged from 2 to 17 percent, while the unsoaked values ranged from 4 to 25 percent.

Abstract:

Comparative assessment of the average monthly global solar radiation on horizontal surface for Owerri has been carried out with the use of five Angstrom sunshine base models. Thirty years (1992 - 2022) of average monthly global solar radiation and sunshine hours are sourced from NASA and NIMET, respectively. The sunshine-base models are evaluated with the use of geographical and metrological data of Owerri and comparison is made based on estimated statistical error indices of Mean Bias Error (MBE), Root Mean Square Error (RMSE), Mean Percentage Error (MPE), Coefficient of Determination (R2) and percentage error to assess the applicability accuracy of the models. Results obtained shows that regression equations of Fagbenle and Page models satisfied viability criterion of MBE, RMSE, and MPE being close to zero, the R2 values are reasonably close to unity and the percentage error agreed to within ± 10% of the measured average monthly global solar radiation on a horizontal surface in Owerri. Rietveld model closely followed with less prediction accuracy to those of Fagbenle and Page models, while, Glower and McCulloh and Turton models yield poor estimation of the average monthly global solar radiation on horizontal surface.

Abstract:

A total of sixteen rabbits sourced from two locations in Southeastern Nigeria were used for this study. Semen was collected from all the rabbits twice weekly for eight weeks using an artificial vagina while observation on the effect of time of collection on semen quality were also made. The results obtained indicated that time of collection had no significant effect (P > 0.05) on all the seminal characteristics measured. However, source of the animals showed significant effect (P < 0.05) on semen volume, sperm concentration, total sperm per ejaculate and proportion of abnormal sperm. Average semen volume, sperm concentration and total sperm per ejaculate were: 0.69±0.007 ml, 104.0±1.44 x 106/m1 and 71.40±0.90x106 respectively for the rabbits sourced from Port Harcourt. The corresponding values for rabbits sourced from Owerri were: 0.66±0.008m1, 96.02 ±1.63x106iml and 63.49±1.50 x 106 respectively. Abnormal sperm proportions were 11.05±0.22% and 1216 ± 032% for the rabbits sourced from Port Harcourt and Owerri respectively. There were no significant (P> 0.05) differences observed between locations in live sperm concentration and sperm motility. Live sperm concentration and sperm motility were 87.75±1.09% and 71.62±0.74% for the Port Harcourt group, while the values obtained for the Owerri group were 88.06±034% and 71.19±0.89% respectively.

Abstract:

The study's objective was to evaluate self-medication habits and side effects among employees at the Federal Medical Centre in Owerri, Imo State, Nigeria. To direct the study, six objectives, six research questions, and four research hypotheses were developed. The study used a cross-sectional research design. Four (4) departments and respondents were chosen utilising a multi-stage sample technique and simple random technique. 436 workers in all were chosen for the study. A self-created questionnaire served as the data collection tool. The test-retest approach was used to establish the instrument's reliability and the spearman rank order correlation coefficient produced a positive result of 0.8. Utilising frequencies, percentages, means, and standard deviations, the data was sorted, examined, and summarised. The chi-square, T-test, and ANOVA were used to evaluate the hypotheses at the 0.05 level of significance. The findings indicated that 73% of Federal Medical Centre Owerri employees self-medicated, with problems being the most common (x = 2.87; SD =.765). A greater 94.3% of workers in the 50–59 age group reported using self-medication. Self-medication is more common among female workers than male workers (78.9% versus 69.8%). Workers between the ages of 40 and 49 report more self-medication difficulties (x = 3.02; SD = 1.2). Self-medication issues are worse for female workers than for male workers (x = 2.92; SD =.765). Based on age (x2=11.976, df = 6, p-value =.73) and gender (x2=1.674, df = 1, p-value =.196), there were no appreciable differences in the self-medication practises among employees at the Federal Medical Centre in Owerri, Imo State. The only factor that significantly differed in the problems of self-medication among employees at the Federal Medical Centre in Owerri, Imo State, was age (F(6, 413) = 2.996, p =.000). To keep staff members informed and reeducated about the risks of self-medication, regular workshops and seminars should be organised.

Abstract:

It was hypothesized that changes in price could affect the consumption pattern of petrol, rice and bean, their status as basic needs notwithstanding. To test this hypothesis, primary data were generated, subjected to econometric model and analyzed. Two-hundred residents of different income groups who live in Owerri city, Imo State, Nigeria and have used petrol, rice and bean for at least ten years and were not less thanthirty-one years old were sampled using standard method. The pretest result of questionnaire validity and reliability was r = 0.726 and this indicates high reliability. A total of 90% strongly agreed and agreed that prices of petrol, rice and bean are unstable in Owerri City, Imo State, Nigeria. The results indicate that 70% of the consumers strongly agreed and agreed that price affects consumption of the products irrespective of need. This wasa significant observation too. In the study, availability of petrol, rice and bean affected consumption in an urban environment.Grain quality was found a strong determinant of consumption of rice and bean in the city. There was a positive and non-significant relationship between price and consumption of petrol, rice and bean and this shows that price is not the most important determinant of consumption of all commodities. Necessity was more important than price in consumption of petrol, rice and bean in the city of Owerri, Imo State, Nigeria. These findings are useful to econometricians, policymakers, governments and households. Keywords: Basic needs, Econometric model, Income groups, High reliability, Grain quality.

Abstract:

This study was designed to examine how indigenous socio-cultural practices contribute to the conservation and management of natural resources in Owerri, Imo state, Nigeria. The major purpose of this paper is to investigating the extent to which totemism (forbidden items), creation of protected areas (evil forest, sacred grooves, burial ground), shrines and sanctuaries as indigenous socio-cultural practices contribute to natural resources conservation in Owerri, Imo state, Nigeria. Three research questions and three commensurate null hypotheses were formulated for the study.. The population of the study consisted of farmers, carvers, traders, civil and public servants, conservation organizations among others. The multi-stage sampling techniques, was used to select a sample of 240 respondents from a population of about twelve thousand persons from 12 selected autonomous communities. A structured questionnaire divided into two sections with the modified four point Likert scale response option was the major instrument for data collection. The researcher with the help of trained community secretary administered the instruments and there was a 100% instrument return rate. Pie chart and simple percentage were used to answer the research questions, while Pearson Product Moment Correlation Analysis was used to test the relationship between the sub variables which makes up indigenous cultural practices and the conservation of natural resources at 0.05 significant levels at 238 degree of freedom. The result of the analyses of all the hypotheses were significant indicating that each of the sub-variable constituting indigenous cultural practices contributes to the conservation of natural resources in Owerri, Imo State, Nigeria. It was recommended among others that modern conservation activities should purposely design strategies to incorporate indigenous socio-cultural practices for the conservation of natural resources in the study area and beyond.

Abstract:

Aims: To determine and compare the bacteriological quality of frozen chicken sold in the Capital cities of the South Eastern States of Nigeria. Method: A total of 150 samples (frozen chicken) were collected from different Capital cities (Abakaliki, Awka, Enugu, Owerri and Umuahia) of the five (5) South Eastern States of Nigeria, which were 30 samples each State. The Aerobic Plate Counts (APC), Total Coliform Counts (TCC), Psychrotrophic Plate Counts (PPC), Escherichia coli counts, Staphyococcus aureus counts and the presence of Salmonella spp were determined by plate count technique using the appropriate media. Colony counts were taken from the plates with the specified number of colonies. Results: For the Capital cities which are Abakaliki, Awka, Enugu, Owerri and Umuahia, the samples mean values for the Aerobic Plate Counts (APC) were 9.61×106, 8.50×106, 6.12×106, 8.10×106 and 6.46×106 respectively, the Total Coliform Counts (TCC) were 4.80×103, 5.59×103, 2.46×103, 2.62×103 and 3.72×103 respectively, the Psychrotrophic Plate Counts (PPC) were 5.71×106, 4.57×106, 4.22×106, 5.53×106 and 4.41×106 respectively, the Escherichia coli counts were 2.33×103, 2.68×103, 1.56×103, 1.80×103 and 2.12×103 respectively, the Staphyococcus aureus counts were 5.58×103, 3.93×103, 4.36×103, 4.16×103 and 4.11×103 respectively and the incidence of Salmonella spp were 19, 13, 6, 15 and 16 respectively. Abakaliki with the highest mean values counts and highest incidence was the Capital with the highest bacterial load/contamination. Awka was the Capital with second most bacterial load. Enugu was the Capital with the lowest bacterial load. Owerri and Umuahia were contaminated but had bacterial load lower than those of Abakaliki and Awka samples. The bacterial load of Owerri and Umuahia tends to be equivalent. The mean values of the Capital cities exceed the international permissible limits and there were presence of Salmonella spp Conclusion: The frozen chicken meats sold in the Capital cities of South Eastern States of Nigeria are highly contaminated and can cause food poisoning when eaten raw or under cooked. Therefore, proper cooking should be done before consumption.

Abstract:

Abstract In spite of the several benefits of using free-space optical (FSO) communication systems as complementary platforms for next-generation networks, the existence of atmospheric disturbances such fog and scintillations are key sources of signal impairment that affect system performance. Thus, it is crucial to learn about the specific weather patterns of the areas where FSO lines will be installed. The purpose of this work is to estimate the availability performance of FSO lines broadcasting at both 850 nm and 1550 nm by performing a statistical analysis of meteorological visibility data gathered for Owerri in Nigeria over a 21-year period (2000-2021). The results shows that the visibility during the most common fog events in Owerri is 100 meters. The probabilities of encountering and exceeding the scattering attenuations associated with Owerri’s most common fog event are 0.0002 and 0.0229, respectively. This research could be expanded in the future by exploring the effects of varying localized climatic conditions on the many forms of optical signals, such as plane, spherical, and Gaussian beam waves.

Abstract:

This study assesses groundwater vulnerability in Owerri, Nigeria, using Vertical Electrical Sounding (VES) and Geographic Information System (GIS)-based DRASTIC modeling. The research methodology includes literature review, field survey, geological feature mapping, hydrogeological assessment, geo-electrical sounding, and data interpretation. Owerri, a rapidly developing city with flat topography and a growing population, uses the DRASTIC model to construct a groundwater vulnerability map. The model evaluates the risk of groundwater contamination using seven critical criteria, including depth to water table, net recharge, aquifer media, soil media, topography, vadose zone impact, and hydraulic conductivity. Each parameter was given a weight and rating, and the DRASTIC Index (DI) was calculated by summing the products of the weights and ratings for each factor. The results of the vulnerability assessment indicated that approximately 49% of the study area falls into the high vulnerability category, around 45% is classified as moderate vulnerability, and the remaining 6% is labeled as low vulnerability. The study reveals moderate to high vulnerability zones in Owerri, Nigeria, due to factors like lower slope terrain, permeable aquifer media, and vadose zone impact. The use of VES and GIS-based DRASTIC mapping techniques provides insights into groundwater vulnerability, aiding in sustainable resource management and environmental protection. The findings emphasize the importance of understanding potential risks and the need for effective management strategies to safeguard clean water supplies. Further research and mitigation efforts should focus on highly vulnerable areas.

Abstract:

Background: Coronavirus disease (COVID-19) and malaria syndemic poses colossal challenge in prompt diagnosis and effective management of both infections especially in tropical regions. Therefore, this survey was conducted in order to ascertain the seroprevalence of SARS-COV-2 antibodies and malaria parasite in a Federal University of Technology Owerri, located in the south-eastern part of Nigeria, shortly after the waves of COVID-19 pandemic in 2020. The study was carried out among staff and students in the School of Biological Sciences, Federal University of Technology Owerri, Imo State, Nigeria within the age range of twenty-one (21) and above. Method: A total of 600 randomly selected participants (400 students and 200 staff) who had provided informed consent, were randomly selected from the School of Biological Sciences, Federal University of Technology Owerri. Questionnaires were administered to collect data on respondents’ demographics and clinical history. Then, blood samples were aseptically collected by needle prick and tested for COVID-19 and malaria using the SARS-COV-2 IgM/IgG antibody test kit and the malaria test kit (Malaria Pf (HRP2) respectively. Results: Malaria and COVID-19 co-infection rates observed among the staff and students in this survey were 5% and 1.8% respectively. Out of the 200 staff tested in this study, 45(22.5%) were IgG positive, 0(0%) were positive for IgM while 10(5%) tested positive to malaria parasite. Although, all IgG positives were junior staff. Then, amongst the 400 students tested, 37(9.25%) tested positive for IgG while none (0%) were IgM positive but, 62(15.5%) were positive for Plasmodium falciparum infection. The interrelated symptoms of malaria and COVID-19 mostly observed in our respondents were fever, headache and fatigue. Conclusion: Results from this study further explained that the level of co-infection prevalence varies directly with the level of malaria prevalence and vice versa.

Abstract:

Effective school health service helps to reduce ill health, increase school attendance, academic performance, decrease school dropout rates, and additionally plays a role in identifying children with emotional, behavioural, and mental health problems for proper assessment and appropriate interventions. To assess the status of the school health services in selected public and private primary schools within Owerri Municipal Local Government Area, Imo State. A cross sectional descriptive study was carried out from March to April 2017. Out of the 48 government approved primary schools, 36 (12 public and 24 private) schools within Owerri Municipal LGA were assessed. Relevant data was obtained from school head teachers and direct observation was done where applicable. The responses were scored using a validated School Health Programme evaluation scale. The overall mean score for School Health Services in Owerri Municipal LGA was 13.14 with the mean scores of 14.42 for private and 10.58 for public schools which were significantly lower than the minimum acceptable score of 19. The private schools performed better than public schools in practice of School Health Services and their mean difference was statistically significant (p=0.012). School health personnel were available in fourteen (38.9%) schools, out of which one (8.3%) public school had health personnel. All (100%) schools had first aid boxes, but none of the schools had the boxes completely stocked. School health clinics were available in one (8.3%) public school and 5 (20.8%) private schools. School meals were served in six (25%) private but none in public schools. The overall status of school health services in primary schools within Owerri Municipal LGA is poor. The private schools performed comparatively better than public schools. These findings therefore portray the need for implementation of the National School Health Policy by the State Ministries of Education and Health. Keywords: Implementation, School Health Services, Public and Primary Schools.

Abstract:

Comparative valuation of global solar radiation on horizontal and tilt surfaces with the use of Angstrom-Page and four isotropic models for Owerri has been carried out in this paper. Angstrom linear regression model is developed from thirty years (1992-2022) of sunshine hour and average monthly global solar radiation sourced from NIMET and NASA, respectively. The Angstrom regression coefficients 𝑎 and 𝑏determined for Owerri is 0.210 and 0.696, respectively. The developed model is used to estimate average monthly global solar radiation on horizontal surface and consequently, the amount of incident solar radiation received on tilt surface by the isotropic models. The MBE, RMSE and MPE values are estimated to be 0.0083, 0.0029 and -0.0041%, respectively, for the developed Angstrom-Page model. A strong coefficient of determination of 76.6% was obtained and Analysis of Variance (ANOVA) significant of 100% was observed, which shows the goodness of fitness of the model. Among the isentropic models studied, one of the models poorly estimated solar radiation on horizontal and tilt surfaces for the study location

Abstract:

Youths are faced with immense reproductive health problems and they have limited access to reproductive health services. This study was carried out to investigate the utilization of reproductive health services among youths in Owerri, Southeastern Nigeria. The study was a descriptive cross sectional study and the multistage sampling technique was adopted to select samples for the study. A well-structured questionnaire was used to interview the subjects and obtain data for the study which was uploaded into the SPSS version 21 software and the Chi-square was used to test for association at 5% level of significance. A total of 424 people were studied comprising of 276 (65.1%) males and 148 (34.9%) females. Results showed that only 106 (25%) showing good knowledge of reproductive health services while 318 (75%) showed poor knowledge. Among the 148 that have used reproductive services, 56.8% responded that they seek reproductive services in the home of a health worker, 29.1% seek reproductive health services through public health facilities such as health centers, clinic or NGO, and 14.2% obtain their reproductive health services through drug shops such as a pharmacy or chemist. SPSS analysis using the Chi-square showed that the male gender showed poorer knowledge of RHS than the female gender but gender was not found to be significant (p=0.098, χ2=1.993). Other significant socio-demographic factors include marital status (p=0.0001, χ2= 46.29), living pattern (p=0.005, χ2=6.93) and education (p=0.0001, χ2= 17.8). In conclusion, the study showed that the knowledge and the level of utilization RHS is still low among youths in the study area. It was recommended that stakeholders sensitize the public on the importance of youth reproductive health services and strengthen the idea of youth friendly reproductive health services.

Abstract:

Purpose: The photostress recovery time (PSRT) scores of welders were measured based on age, workexperience and welding-method.Methods: A quasi-experimental study was conducted among 50 purposively sampled welders, who had clear ocular media, healthy fundi and visual acuities of 6/6 or better in the tested eyes. The pre-bleach distant visual acuity of the right eye was determined with the Snellen’s visual acuity chart, while direct ophthalmoscopy was done to rule out media opacities, retinopathies and maculopathies. The right eye was dazzled for 10 seconds with the light of a direct ophthalmoscope held at 2cm from the eye. The time required in seconds to read at least, three optotypes on the line directly above the baseline acuity was recorded as the PSRT.Results: The 22-31 years age group recorded the least mean PSRT (16±8.8seconds), followed by the 32-41 age group (19.9±6.8 seconds), while the 42-51 years category had the highest mean PSRT (31.4±10.5seconds). Age associated significantly (p˂0.05) with mean PSRT. Welders within the 1-12 years’ work experience had the least mean PSRT (15.9±8.1seconds) while those within the 25-36 years recorded the highest mean PSRT (33.4±9.3seconds). The observed difference in mean PSRT with years of work experience was statistically significant (p˂0.05). Gas welders had significantly (p˂0.05) higher mean PSRT (26.6±9.9secs) than electric arc welders (16.6±9.2secs).Conclusion: Gas welding, increasing age and work-experience were found to be predictive markers of elevated photostress recovery time (PSRT) among welders. This underscores the need for eye-care practitioners to routinize PSRT tests in the ocular assessment of welders. Keywords: Photostress recovery time (PSRT); electric-arc; gas welding; welders; age.

Abstract:

Objective: Cryptococcosis is an opportunistic infection caused by Cryptococcus and can result in cryptococcal meningitis, which is an AIDS-defining condition associated with high morbidity and mortality. Although a high prevalence of Cryptococcal antigenemia (CrAg) preceding cryptococcal disease has been reported in HIV-infected Nigerian adults, it is more common in patients with low CD4, stage 3 or 4 HIV. However, there is only one study on Cryptococcal antigenemia in HIV-infected Nigerian children. Therefore, this study aimed to determine the burden of cryptococcosis in HIV-infected children. Material and Methods: This study was a hospital-based cross-sectional study conducted between October 2018 and January 2019 at the Pediatric Infectious Disease Clinic of the Federal Medical Centre, Owerri. The study population consisted of HIV-infected children (aged 2-16 years) attending the clinic. The subjects were recruited consecutively and underwent a thorough physical examination and anthropometric measurements before a single blood sample was taken. Cryptococcal antigen was assayed using the Lateral Flow Assay method, and CD4+ counts were assayed using cyflow. Results: A total of 100 children were involved in the study, of which 51 (51%) were female and 49 (49%) were male (M:F, 1:1). The average age of the participants was 9.73 ± 3.12 years. Among the 100 children tested, there was no cryptococcal antigenemia (0%). Statistical analysis was limited to simple description. Conclusion: Cryptococcosis is not a common opportunistic infection among HIV-infected children attending the Pediatric Infectious Disease Clinic in Federal Medical Centre Owerri. Therefore, it may not be considered as a differential diagnosis for HIV-positive children with meningoencephalitis.

Abstract:

Background: Booking in pregnancy has been found to significantly influence the maternal and perinatal outcome of pregnancy. Unbooked pregnancies contribute to adverse maternal and perinatal outcomes. Some paturients in Owerri, South eastern Nigeria and environs have the erroneous idea that booking was not important for safe motherhood. Objectives: The study was to determine the maternal and perinatal outcomes of unbooked versus booked pregnancies.The maternal outcomes examined included normal deliveries, instrumental vaginal deliveries, caesarean sections and maternal mortality. The perinatal outcomes included an evaluation of Apgar scores and perinatal mortality.Design: It was a retrospective comparative studySetting: The study was carried out at the Federal Medical Center,Owerri South-eastern Nigeria between January, 2010 and December, 2011. Methodology: The labour ward records of all deliveries in the Centre between January 2010 and December 2011were examined and data collected from the theatre and Special care baby unit to determine the maternal and perinatal outcomes. Paturients who registered their pregnancies and received antenatal care in the Centre were termed booked, while those seen in labour for the first time irrespective of whether they registered elsewhere or not, were termed unbooked. Data was analysed using standard electronic calculators. Results: There were a total of Six thousand, six hundred and seventy five (6675) deliveries within the period under review with a total of 680 unbooked pregnancies giving an overall incidence of 10.2%. The incidence was10.12% for 2010 and 10.24% for 2011respectively. In all the indices used to assess maternal and perinatal outcome, there was a more favourable outcome in the booked parturients compared to those who were unbooked. Conclusion: The study goes on to re- emphasize the contribution of the unbooked mother to bad obstetric indices. The unbooked mother increases the risk of operative deliveries, maternal mortality, birth asphyxia and perinatal mortality.

Abstract:

Physico-Chemical and bacteriological characteristics of eleven boreholes located within Owerri city were examined. The bacteriological analyses were carried out using the method of inoculation and incubation of specimens and counted on colonies. Titration method was used to determine chlorides and nitrates while Cu2+, Zn2+ and Mn2+ used atomic absorption spectroscopy (AAS). Iron concentration was read off using benzylideneacetone (BDA) Lovibondcolour comparator while the total dissolved solids were determined gravimetrically. The water is usually clear at average temperature of 27˚C. The bacteriological parameters are within the acceptable World Health Organization (WHO) standard and safe for human consumption. The pH is 6.0 -7.5, total dissolved solids vary from 12.4mg/l to 49.4mg/l. The anions of chloride and nitrate are 67mg/L to 125mg/L and 0.003 mg/L to 23.1 mg/L respectively. Concentrations of cations include iron; 1.86mg/l, copper; 1.2mg/l, zinc; 2.1mg/l and manganese; 0.05mg/l. The results show that the groundwater within the city is suitable for drinking and other uses compared to the WHO standard. The environmental conditions of the borehole locations as well as the total drill depth should be emphasized. Government monitoring agency should ensure adequate drill depth to at least 200ft in the south- western area and north- eastern areas from 250ft to 300ft as this may reduce the injurious variations in the geochemical parameters in some boreholes.
