EFFECTS OF AN 8-WEEK INTERMITTENT AEROBIC EXERCISE ON THE ELECTROCARDIOGRAM AND PHYSIOLOGICAL PARAMETERS OF INSTITUTIONAL SECURITY PERSONNEL IN NIGERIA

This study determined the effects of an 8-week intermittent aerobic exercise training on the resting electrocardiogram and physiological parameters of institutional security personnel in Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC). The study adopted a pretest-posttest-control group experimental design. The population for the study were male security personnel of OAUTHC, Ile-Ife. Forty middle-aged volunteers who met the inclusion criteria were randomly assigned to either of Intermittent Training Group, ITG (n = 20) or control (n = 20). A structured exercise training programme, Intermittent Exercise Training Programme was used to train the ITG for 8 weeks. Resting ECG was recorded pre and post-intervention with a 12-lead Electrocardiograph, weight and height were measured with an electronic BMI scale. Blood pressure was recorded before and after exercise sessions. Participants in ITG performed the 12-minutes run/walk test before and after the 8 weeks intervention. Borg’s rating of perceived exertion scale was used to gauge exercise intensity and a structured data sheet was used for recording data. Paired- sample t- Test statistics was used to analyse data. The results showed that intermittent aerobic exercise training neither produced significant effect on the resting ECG parameters in terms of intervals; RR- interval (t = -0.79; p > 0.05), P- wave duration (t = -0.64; p > 0.05), PR- interval (t = -0.08; p > 0.05), QRS- Complex (t = -0.99; p > 0.05) and QTC (t = -1.20; p > 0.05) nor axes P- Axis (t = -0.06; p > 0.05), QRS- Axis (t = 0.78; p > 0.05) and T- Axis (t = 0.60; p > 0.05). It however affected participants’ heart rate (t = 4.41; p < 0.05) and VO2 max (t = -11.25; p < 0.05). The study concluded that intermittent aerobic exercise training produced no significant effect on the resting ECG parameters but significantly reduced heart rate and increased VO2 max.  Article visualizations

ANTHROPOMETRIC AND PHYSIOLOGICAL CHARACTERISTICS OF INSTITUTION-BASED SECURITY PERSONNEL IN NIGERIA

This study investigated the anthropometric and physiological characteristics of institution-based security personnel in Nigeria. The study adopted a descriptive survey research design. The population for the study were the male security personnel of the Obafemi Awolowo University (OAU), Ile-Ife, Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC), Ile-Ife and Wesley-Guild Hospital (WGH), Ilesa, Osun State. Sample comprised sixty middle-aged volunteers drawn from the Security Departments of the three institutions. Inclusion criteria for the study was passing a preliminary health screening for cardiovascular disease risk factors. Anthropometric parameters were measured in line with the International Society for the Advancement of Kinanthropometry (ISAK)’s protocol. Participants’ weight and height were measured with an Electronic BMI scale and blood pressure was recorded using Aneroid sphygmomanometer. Participants’ VO2 max was estimated from the Cooper 12-minutes run/walk test. Data was recorded in a structured data sheet. Descriptive statistics of mean and standard deviations was used to analyse data. The results showed that the mean age of security personnel in the study was 41.7 ± 5.749, while their mean height and weight were 171.0 ± 7.353 and 69.2 ± 7.322 respectively. The mean of personnel’s waist and hip circumferences were 40.68 ± 3.968 and 46.68 ± 2.813 respectively. The mean of skinfolds (Ʃ4 Skf), percent body fat, waist-to-hip ratio, and BMI of security personnel were 50.03 ± 15.797, 22.37 ± 5.175, 0.87 ± 0.062 and 23.66 ± 2.386 respectively. Their mean resting heart rate, systolic blood pressure, diastolic blood pressure and VO2 max were 63.77 ± 8.77, 119.42 ± 9.30, 80.17 ± 8.54 and 43.95 ± 43.95 respectively. The study concluded that institution-based security personnel are similar to the civilian population in terms of anthropometric and physiological characteristics.  Article visualizations

Comparative Quality Evaluation of Oven-Roasted and Honey-Coated Cashew (Anarcadium occidentale, L.) Nut produced using Locally Fabricated Cashew Nut Processing Machine in Nigeria

— Raw cashew nuts were processed to obtain cashew kernels. Part of the kernels was roasted using mud oven while another part was honey coated and dried. The two samples were subjected to chemical, microbial and sensory analysis to compare their quality attributes. Differences were observed in some chemical compositions of the two samples; moisture content value of the oven roasted kernel was significantly (

Job Satisfaction of Academic Staff Members on Full-Time Appointment in South-Western Nigerian Tertiary Institutions

Man works to earn a living in an organization, and such work can be viewed as an instrument employed to achieve a lot of set personal goals and expectations. This study, therefore, examines job satisfaction of staff members on full-time appointment in South-western Nigerian tertiary institutions. It is a quantitative research in which a well-structured questionnaire was used to collect responses across eighteen tertiary institutions in South-western Nigeria. A purposive random sampling method was adopted to select a representative sample, and 880 questionnaires were properly selected and analyzed. The validity and reliability tests indicated that the measurement scales met the acceptable standards. Charts were used to present the biographic information of the respondents. The data obtained from the investigation were analyzed using Charts, Correlation Analysis, Regression Analysis and some relevant statistical tools. The findings have revealed a high factor of the academic staff’s dissatisfaction with opportunity available for self-development because of poor research environments. Moderate proportion has also revealed staffers’ satisfaction with their job. Factors leading to job satisfaction were also revealed. The study, therefore, suggests that Chief Executives of Nigerian tertiary institutions should focus on the identified factors leading to job satisfaction such as good remuneration and welfare package, appreciation and commendation, adequate facilities and teamwork etc. Implementing the aforementioned factors will definitely increase job satisfaction among the academic staff on full-time appointment, thus, reducing the friction rate and creating a stable and reliable teaching/learning environment for academic staff and the students.

Analysis of Groundwater Pollution from an Unlined Constructed Wetland Sludge Drying Bed

Sludge drying beds (SBDs) are part of wastewater treatment processes where dewatering and reduction of water content from the substrate sludge take place to enhance caking and thus facilitate handling and disposal. In this study, the effect of the operation of an unlined drying bed of a constructed wetland for domestic wastewater treatment on the adjourning groundwater was investigated. Experimental boreholes for water quality monitoring were constructed downstream of the SBD prior to its operation. Preliminary investigations of the quality of water in the boreholes were carried out before the operation of the SBD. The concentration levels of pH, Conductivity, Total Dissolved Solids, Colour, Mn, Fe, SO4, NO3, Total Coliform and e-coli were used to empirically and statistically determine the level of pollution of the ground water during the operation of the SDB. The 2-way ANOVA at (=0.05) showed that the operation of the SBD had statistically significant impact on the quality of the groundwater on all the observed parameters. For the parameters observed, p<0.05 (p=0.00 for the averages of pH, EC, TDS, Turbidity, Colour, Mn+2, Fe+2, SO4 and NO3), while p=0.0028 and 0.0018 for the averages of Total coliform and E.coli respectively in all the boreholes. The distances from the discharge point of the SDB were at 15m, 20m, 25m, 30m, 35m, 40m and 50m for boreholes 1, 2, 3, 4, 5, 6 and 7 respectively. Also, comparison of the means of the quality parameters with the allowable limits set by the Nigerian National Environmental Surface and Groundwater Quality Control Regulations (NSGQCR) indicated that the operation of the SBD rendered the quality of the groundwater unacceptable

MODELLING OF GROUND LEVEL CONCENTRATION OF PARTICULATE MATTER IN MAJOR NIGERIAN UNIVERSITY AIRSHED

Modelling of air pollutants for air quality assessment has been an important landmark achievement by environmentalists especially in areas where on-the-field monitoring is not economical. Models have proven to be cost-efficient and predicts better with different sample sizes. The objective of this study was to model the particulate matter pollutants of a major Nigerian university airshed and to compare of the predicted results with regulatory standards. Dispersion modelling analysis using for line and point sources study of the university airshed was carried out. Prior to the use of the modelling tool, vehicular counts, emission estimation and loads for the two pollution sources was done. The predictions revealed that concentration levels of PMs to emission source and receptor environments for the line source study were extremely high due to factors such as emission height and meteorological conditions of the university. The predicted concentrations from the point source were moderate and the reason is due to the emission height (stack height), wind speed and direction. Other contributing sources could be as a result of biomass burning, bush burning and pollutant transport. This study will be a bedrock for institutional-based air quality assessment that checkmate the anthropogenic contribution to deteriorating ambien

RISK SURVEILLANCE OF MULTIDRUG RESISTANT PSEUDOMONAS AERUGINOSA IN WATER AND PLASMID RELATEDNESS WITH CLINICAL STRAINS IN ABEOKUTA, SOUTHWEST NIGERIA

Pseudomonas aeruginosa as an opportunistic pathogen has been a subject of investigation due its intrinsic drug resistance.ª¤?ª¤? Its frequent presence in drinking, domestic and recreational water highlights its significance to public health.ª¤?ª¤? This study was aimed at risk surveillance of multidrug resistant environmental P. aeruginosa in water and their plasmid relatedness with clinical strains in Abeokuta, southwestern Nigeria.ª¤?ª¤? A total of forty-one (41) strains with prevalence: well water (29.3%); swimming pool (22.0%) hospital storage tank (19.5%); tap water (14.6%); sachet water (12.2%); and bottled water (2.4%) respectively were isolated from two hundred and eighty eight (288) water samples and were compared with 43 clinical strains from wound (37.3%), blood (11.6%), ear swab (20.9%)ª¤? and urine (20.9%)ª¤? and eye swab (9.3%).ª¤?ª¤?ª¤?ª¤? Both environmental and clinical strains were all multidrug resistant, though with different plasmid profile.ª¤? Plasmid with molecular weight size of 2010bp was detected in only 1 (2.5%) out of the 41 environmental strains as against 9 (20.93%) of the 43 clinical strains having between 22520-23130bp molecular weight.ª¤? All strains harboring plasmid were resistant to varied types of more than seven drugs out of the eleven tested (gentamycin 10ª¤?g, erythromycin 15ª¤?g, ampicillin 10ª¤?g, augmentin 10ª¤?g, cotrimoxazole 25ª¤?g, tetracycline 30ª¤?g, streptomycin 10ª¤?g, ciprofloxacin 5ª¤?g, cloxacillin 5ª¤?g, amoxicillin 25ª¤?g, and cefuroxime 30ª¤?g). ª¤?Strains without plasmid were also multidrug resistant.ª¤? This finding would be important in the control of multidrug resistant Pseudomonas aeruginosa infection in Nigeria
