Abstract:
Analysis and study of the vertical variation of refractivity in the troposphere is required for radio systems planning in order to achieve successful operation. The diurnal variation of surface radio refractivity over three meteorological stations in Nigeria is presented. The stations include Lagos-Ikeja (6⁰35’N, 3⁰40’E), Akure (7⁰15’09”N, 5⁰11’35”E) and Minna (9⁰37’N, 6⁰32’E). Monthly mean values of temperature, pressure and relative humidity were used to compute refractivity for three stations. The surface refractivity also shows latitudinal and seasonal variation. The maximum refractivity values were obtained for Ikeja (Lagos) of 394 N-units, Akure of 404 N-units and Minna of 364 N-units.

Abstract:
Atmospheric weather parameter is dynamic in nature, hence the need for continuous investigation of the anomalous propagation phenomenon. The coastal region is more unique in its characteristics due to the rapid and continuous variation in the weather parameters. This paper presents the results from 10 years (2006 – 2015) of reanalysis data of meteorological parameters (temperature, relative humidity and atmospheric pressure) obtained from European Center for Medium-Range Weather Forecasts (ECMWF). The data covers some selected stations in the coastal region of Nigeria namely: Port-Harcourt, Warri, Calabar, Arogbo, Oron, Yenagoa and Lagos Island at four synopsies hours of the day (6 hrs, 12 hrs, 18 hrs and 24 hrs). The resolution of the ECMWF data is 0.25 by 0.25. Radio refractivity, refractivity gradient, point refractivity and geoclimatic factor are estimated from the data. Subsequently, the results were used to deduce percentage of fade depth exceedance. The overall resultsa will assist to ascertain the level of signal degradation due to multipath fading and fade depth over the coastal regions of Nigeria

Abstract:
Mobile communications are part of our everyday life. The non-ideal environment which is filled with many attenuation factors affects the electromagnetic waves, which radio communication depends. This study considers the spectral range of 1 and 3GHz. At these frequencies, interesting phenomena due to rain are supposed to happen. The study of this frequency spectrum has been undertaken in an attempt to evaluate the frequency dependence of rain effects on electromagnetic waves. The study of rain effects on communication presented in this study relied solely on rainfall data collected from Nigeria Metrological Agency (NiMet) station in Lagos, Nigeria. The months for January to December for 1981-2011 were summed together and the averages were determined. The average is then used to calculate the rain rate and rainfall attenuation using the extracted results for all the locations (Bauchi, Ikeja, Jos, Kebbi, Maiduguri and Warri). The results show that Warri has the highest rainfall rate followed by Lagos. Kebbi and Maiduguri has the least while Jos and Bauchi demonstrated moderate rainfall rates. This also deduced that attenuation has less impact on lower frequencies but increase with higher frequencies. The study reveals that at higher frequencies, the rainfall attenuation is observed to be greater.

Abstract:
Abstract Lagos, Nigeria (6.35°N, 3.2°E), is a coastal station in the rain forest area of southwestern Nigeria with an altitude of 38 m. Since most communication now takes place above the X band because of congestion of lower bands, it was necessary to look into ways of maximizing X-band usage. There are inadequate data for use in rain propagation studies at microwave frequencies, and even less so at millimeter wave bands where most of the signal depolarization and fading has been discovered to exist. The proposed model is a modification of the International Telecommunication Union–Radio Communication Sector (ITU-R) model combined with locally obtained regression coefficients for estimating specific attenuation as proposed by G. Olalere Ajayi. The Dissanayake, Allnutt, and Haidara (DAH), Simple Attenuation Model (SAM), and ITU-R attenuation prediction models were investigated along with the proposed model. The ITU-R model was observed to produce the best results at 40 GHz, with percentage error values of 0.61%, 0.55%, and 0.49% at 0.1%, 0.01%, and 0.001% of the time, respectively. In comparison, the proposed prediction model showed good performance at 20-GHz down-link frequency, with percentage error values of 3.6%, 3.3%, and 2.9% at 0.1%, 0.01%, and 0.001% of the time, respectively. The obtained results also showed good agreement with other similar works in the open literature. The results presented in this work are valuable for the design and planning of a satellite link in the tropical regions.

Abstract:
This paper fosters the importance and need of international cooperation for use & promotion of Information and Communication Technologies for economic change in Nigeria among professional accountants. The concept of “Information Society” has made it imperative that no country can develop without involving and focusing on regional and global development perspectives. Collaboration has become the key word. When we talk of integrated socio-economic change, it takes into account many areas which can benefit from faster access and enhanced productivities by using ICT. Some case studies on use of ICT for different initiatives within Nigeria are reviewed and conclusions drawn on how it does support the socio-economic change and development, which may be similar and bear lessons for other developing countries. The supply side of ICTs has increased substantially in Kenya. For example, the number of mobile phone subscribers has more than tripled over the past five years, while FM radio stations have proliferated all over the country. There has been a lot of enthusiasm on internet usage with the landing of three undersea fibre optic cables in Lagos and their subsequent operationalization. Marxs of mobile phone service providers and communication equipment now dot both the rural and urban landscapes, and advertisements for some form of ICTs are common on billboards along major highways and roads.

Abstract:
Distribution and variation of anomalous radio propagation, temperature and relative humidity anomalies were obtained and analyzed using six years (2010-2015) Era interim data. Seasonal spatial distribution of refractivity gradient and its components were analyzed. The result showed that about 90% of wet component contributed to the variation of refractivity gradient. Highest range of refractivity gradients and its wet components were obtained during the wet season. The result of correlation between ducting occurrence and temperature showed strong negative correlation except in Lagos where positive correlation of 3% was observed. However, positive correlation which ranges between 39% and 70% exist between duct occurrence and relative humidity except in Lagos in Nigeria. Refractivity gradients, relative humidity anomaly and temperature experience a monthly variation. These variations can be attributed to the seasonal movement of inter-tropical discontinuity (ITD) across Nigeria. Keywords: anomalous, anomaly, correlation, ITD

Abstract:
The restrained use of millimeter bands is due to severe rain attenuation. Attenuation is caused when rain cells intersects radio wave’s propagation path; resulting in deep fades. The effect of rainfall is more severe in tropical regions characterized by heavy rainfall intensity and large raindrops; hence, rain attenuation analyses are essential to study rain fade characteristics for use in earth-space link budget analysis, for outage prediction resulting from rain attenuation. Tropical regions are particularly challenged with signal outage, necessitating the formulation and development of suitable prediction model(s) for the region. Therefore, extensive knowledge of the propagation phenomena mitigating system availability and signal quality in these bands are required. Daily rainfall data were collected from the Nigerian Meteorological Services for Lagos for spanning January to December 2010. Results showed that although, the ITU-R model out-performed the other prediction models under consideration, none of prediction models matched the measurement data.

With an unprecedented population and rapid urbanization, the solid waste collection and transportation has become a major challenge in Lagos metropolis. The main objective of the study was to optimize routes for solid waste collection and disposal using Geographic Information System (GIS) in order to improve solid waste management system in Lagos metropolis. Data on the GIS Network Analyst was used to determine movements between the transfer loading stations and the landfills to determine the collection time, travel distances, optimized routes and alternative routes for solid waste disposal while maximising total solid waste collection and disposal for environmental sustainability. Based on the findings, the study therefore recommends possible interventions such as regular collection of solid waste, proper management of the transfer loading stations and landfills, and that the collection of solid waste should be given more attention because it is important in the development of cities.

Abstract:
The pollution status of Lagos Lagoon was investigated to determine some physical and chemical parameters, in order to further understand its water quality. Five locations were selected according to the anthropogenic activities taking place in the areas. The measured parameters are water temperature, salinity, conductivity, pH, dissolved oxygen (DO) and alkalinity. The mean values ranged from 28.50-30.15°C for temperature, 7.86-8.50 for pH, ND-10.60‰ for salinity, 0.18-15.20µS/cm for electrical conductivity, 12.00-14.00 mg/l for alkalinity and 1.60-6.40 mg/l for dissolved oxygen. The statistical analysis of the measured physicochemical parameters revealed non-significant difference (p>0.05) across all stations in the physico-chemical parameters. Generally, the values obtained suggest the influence of anthropogenic activities especially the depletion of DO in most of the stations. Therefore, point source and non-point source pollution into the Lagos Lagoon should be controlled for the health and safety of the aquatic ecosystems. Generally, all the measured parameters were either below or within the permissible limits obtainable in the marine environment.

Abstract:
Abstract Using the available upper-air data for three stations in Nigeria (Lagos, a coastal station; Minna, an inland station; and Kano, a sub-Sahelian station), an intensive examination has been carried out on the linkage between surface mixing ratio rs and layered integrated water vapor W (g cm−2) over Nigeria. The goal was to identify the seasonal distribution of the parameter and to develop models that can best be used to estimate W from surface mixing ratio. To achieve these objectives, integrated water vapor at the low level (WL), midlevel (Wm), and upper level (Wu) and total column integrated water WT have been calculated using daily values of upper-air data spanning over a decade from the above three radiosonde stations. A relationship of the form W = αrs + β (where α and β are constants) has been established between W and rs using the analysis-of-variance (ANOVA) technique. Tests carried out on the models, using daily soundings made in 1990 for Lagos, 1983 for Minna, and 1991 for Kano, respectively, gave encouraging results as established by the use of Kolmogorov–Smirnov tests. Owing to the difference in the climatological patterns of precipitation among the different regions in Nigeria (i.e., southern, midland, and northern regions) as represented by the three stations, no single relationship was found to be suitable for the entire country of Nigeria. Earlier models, generally of the form W = αqb (where α and b are constants and q is specific humidity), were found to be less adequate over the stations.

The study investigated the media use preference among coconut farmers in the western zone of Lagos state, Nigeria. A total number of 120 coconut farmers were selected for the study. Data were collected with the use of interview schedule and analyzed with frequency count, percentage, mean and Chi-square statistics. The usage mean rank showed that mobile phone (mean=4.49), radio (mean=4.47) and television (mean=4.09) were ranked first, second and third respectively. The highest ranked preferred media were radio (mean=4.63), agricultural extension officers (mean=4.43) and fellow farmers (mean=4.36). Chi-square analysis showed that there was no significant relationship between the coconut farmers’ media preference and their socio-economic characteristics. The study conclude that mobile phone, radio and television are the most frequently used media by coconut farmers in the study area. The study further averred that coconut farmers preferred radio, agricultural extension officers, television, family and friends as a medium of communication. The government and non-governmental organizations should intensify the dissemination of information to the coconut farmers using media such as radio, agricultural extension officers, television since that is the most preferred media.

Abstract:
Education has been identified as one of the most important ways to achieve national development. With 3 million non-literate adults in Lagos State, the commercial nerve center of the nation, radio becomes a veritable medium to teach such adults who, for several reasons including economic, do not have the opportunity of formal schooling. The study assessed the effectiveness of educational radio broadcasting for adult literacy in Lagos State, Nigeria. Five hundred and five (505) adult learners participating in Lagos is Learning Project were purposively selected. Findings showed that a majority (62.4%) of the study participants used the instructional radio program, Mooko Mooka, to prepare for classroom instruction, while 53.5% of the study participants used the program for revision. Findings also revealed that 40.6% of them listened to the program three times per week and this implied that frequency of exposure could influence literacy skill. The study concluded that radio instructional techniques were effective in promoting adult literacy and therefore recommended that the radio listening sessions should be increased as part of efforts to reduce adult illiteracy in the country. Also, community media centers should be created in different communities to encourage group listening where learners can be supervised.

Abstract:
AbstractThe physico-chemical parameters, plankton and macro-benthic invertebrates of the Lagos Lagoon (Badore, Ajah), Lagos State, Nigeria were studied between February and July 2018 at four sampling stations in a disparate range of human activities and impact. The result of phytoplankton analysis indicated a total of 56 genera with 40 genera within Bacillariophyta, accounting for 72% of the abundance. Zooplankton comprised 26 genera with 82% of the abundance of crustacea. The benthic macroinvertebrates were composed of mollusca, arthropoda and annelida. Results also indicated that the main drivers affecting the abundance and distribution of planktonic and benthic invertebrates were water temperature, pH, TDS and EC. The monthly variations of physico-chemical parameters in the Lagoon could be the result of human activities associated with transportation, fishing and domestic sewage disposal from the surrounding settlements. Therefore, it is necessary that relevant authorities keep in check some of these activities around the Lagoon as well as educate the population on the necessity for the conservation of these water resources.

Abstract:
AbstractNoise is an inevitable part of daily life and has been identified as a cause of several health deficiencies across the world. It has increasingly become a significant concern on the health and well-being of people. Studies are required to advance knowledge on the sources and impacts of noise in residential neighbourhoods of Lagos State, Nigeria. Therefore, this study assesses the spatial variation of noise levels within a section of the Festac residential area in Lagos in line with noise limits specified by the World Bank Group International Finance Corporation (IFC) Environmental, Health, and Safety (EHS) Guidelines and the Nigerian National Environmental Standards and Regulations Enforcement Agency (NESREA) Noise Standards and Control guidelines for community noise. Data for this research come from a field study comprising measurements of noise levels from 6 observation stations and questionnaire survey with 200 respondents. The criteria for siting the stations was based on factors such as proximity to the roadside, land use and population density, while the questionnaire was administered at random to assess the peoples’ level of awareness on the sources and effects of noise. A digital sound level meter was used to measure noise level variations over a period of 3 weeks for morning, afternoon and evening periods. The measured noise levels were analysed using Analysis of Variance (ANOVA) statistics and the Kriging Geostatistical interpolation technique. Also, logistic regression was used to determine the relationship between the respondents’ perceptions to noise and noise levels. The results indicated that the mean noise levels were within the approximate range of 53.5 – 94.0dBA over the entire period. The highest mean noise levels occurred in the north-western part of the study area where a bus park is present. In general, the noise levels in the area surpass the recommended noise limit of 55dBA, and the logistic regression showed that morning, afternoon and evening mean noise levels were significant predictors of noise variation as perceived by the dwellers. Proper legislation to regulate human activities with respect to noise generation is highly recommended to the local, state and national legislators.

Abstract:
Based on a case study of Iyana Ipaja, one of the largest transport hubs with a spacious motor park and the most vibrant markets in North Lagos, we elaborate on the nuances of interactions between commercial actors and various forms of infrastructure in the spatial and temporal senses. In terms of materiality and mobility of their businesses, commercial actors are categorised into three types, shopkeepers, stallholders and hawkers. They have extensive interactions with the objects with which they are attached (shops, stalls and goods), the physical infrastructures (vehicles, roads, bus stations and motor parks), and ‘people as infrastructure’ – a term coined by Simone – including drivers, passengers, passers-by and government agencies. We suggest that a modification to the concept of ‘peoples as infrastructure’ should help to articulate interactions among differently positioned actors. We argue that the localities and mobilities of commercial practices manifest spatial conviviality among peoples as infrastructure. The temporality of their commercial practices is embedded in the urban rhythm of Lagos and remediates the flows of people and vehicles through the spaces of Iyana Ipaja. The focus of commercial actors provides a new perspective to rethink grassroots spatial politics of motor parks in Nigeria. Moreover, this case study critically engages the theory of relationality of ‘people as infrastructure’ in urban Africa.

Abstract:
In the past decade-plus there has been a paucity of comparative studies of the performance of public transport options in Lagos. This study evaluates commuters’ access to public transport modes (yellow bus, BRT and ferry), trip characteristics, factors influencing choice of, and the performance of each mode in Lagos to establish improvement priorities. Research data was obtained from 124 commuters through close-ended questionnaire at selected terminals on a major corridor during the morning peak period using incidental sampling technique. The performance of public transport modes was measured using seven variables on a 5-point rating scale. Analysis of variance show significant variation in commuters’ trip cost to terminals. The BRT is the most affordable with respect to fare but has the worst boarding delay occurrence, the ferry is the most efficient with respect to trip time while 45% of yellow bus passengers spend more than one hour per trip. From the linear regression results, delay time at the terminals, travel time and travel cost to destinations accounted for about 55.8% of the total variance in the preferred mode of travel. From the relative performance analysis results, the BRT has the highest mean performance index of 3.72, followed by ferry (3.01) and the yellow bus (2.62). These findings facilitate our understanding of factors influencing the performance and choice of public transport modes in Lagos while providing insights into areas needing attention for improvement. Based on these findings, the study recommended the provision of more BRT buses to reduce the waiting time at terminals, and the review of ferry operations to reduce fare and enhance safety and introduce measures to upscale the services of the for better performance. Future studies should explore commuter waiting and comfort at bus stations and terminals and on-board time use.

Abstract:
Decree No. 38 of 1992 enacted under the administration of General Ibrahim B. Babangida put a stop to fifty seven years of government’s exclusive ownership and operation of broadcasting in Nigeria. However, with the cost of setting-up, management and obtaining license for media station being prohibitively expensive, the system can only be accessed by the rich and powerful in the society, thereby depriving rural communities’ involvement in the development of the country. As part of the panoply of strategies to ensure rural communities’ participation in democratic governance, there is need for the establishment of rural community radio stations, which is very much different from educational institutions’ type currently being paraded as community radios but rather a training room for communication and theatre arts students. Using historical-analytic method, this article looks at the role community radio could play in making good governance in Nigeria accessible to every segment of society, especially the rural populace. Therefore, it is recommended that Nigerian Broadcasting Commission (NBC) policy should consider the inclusion of community radio as the third in the sector of radio broadcasting in Nigeria after public and commercial ownership. Furthermore, since community radio is essentially non-for-profit, government should make the operation licence free or at a minimal cost to the host community.

In this study, monthly surface net radiation data were collected from the Nigeria Meteorological Agency, Lagos covering a duration of 31 years (1983- 2013) spatially distributed across the four climatic regions: Semi-Arid (SAR), Sub-humid Dry (SHD), Sub-humid Humid (SHH) and Humid (HUM) regions. The net radiation was evaluated using different forms of Auto-Regressive models – AR {p} where p is the number of orders of the auto-regressive. The analysis showed that AR {4} performed best in all the regions and stations investigated. Regionally, AR {4} has maximum values of coefficient of determination of 0.8127 in HUM, 0.7876 in SHH, 0.5765 in SHD and 0.7973 in SAR regions. It can be concluded that the higher the order of auto-regressive models, the more accurate estimation of net radiation it will give irrespective of location in Nigeria.

Abstract:
The ever-increasing number of mobile telecommunication base station as a result of increasing demand for broadband applications has raised a growing concern and worry over the health implications and safety of the radiations from these base stations by the resident of Ekiti State and Nigeria in Nigeria. Measurement of radio frequency was conducted in this research in order to study the electromagnetic field radiation level in Ekiti State Nigeria. Investigation was conducted with the four available mobile operators with the three sub-frequency band viz 900 MHz, 1800 MHz and 2100 MHz. The power density of radio frequency radiation was estimated through measurement with the aid of A 3-Axis RF Radiation Strength Meter TM-196 and Handheld Spectrum Analyzer Model NA-773, 144/430. The peak and average power density was computed using the method of theoretical calculation and the safety distance from the antennas were estimated. The measured and the calculated values were compared with the international commission on non-ionizing radiation protection (ICNIRP) standard for public and occupational exposure level. Results show that the radiations from the base stations adheres to the standard provided by ICNIRP

Abstract:
The ongoing mobile communication technology intensification had occasioned the inevitable multiplications in the ratio of the radio frequency base service stations which had raised public consciousness over the considerable health hazards of the radioactive emissions from the communication systems. The current paper analysed the sequences of electromagnetic field measurements performed on the selected three states in the North West Nigeria in order to establish the compliance of radiation levels of cellular base stations and wireless fidelity access points with respect to internationally approved recommendations. The measured power densities of wireless fidelity access points are minimal and do not surpass 1% of the level allowed by International Commission on Non-Ionizing Radiation (ICNIRP). The result confirmed the environmental safety of the RF energy maintained by the telecommunication operators within the general public indicating an insignificant health hazards to the citizens.

Abstract:
Nigeria with a population of over 140 million, with 187 radio stations, and 143 television stations, the largest in the African continent, quickly accepted the technology switchover system in broadcast as it will seriously affect the people and Government of the country if not managed. Nigeria joined the global digitalization train, with specific switchover date fixed at June 17, 2012, three years ahead of the International Telecommunication Union, ITU, global deadline set date for 2015 for the entire broadcasting stations in the world to go digital. The truth is, Nigeria never went digital with respect to the June 17, 2012 switchover date. A new switch over date of 2015 was set, but there is doubt if the new target date could be met. The strengthening of public awareness and education on what digitalized broadcasting involves and what is needed to be put in place by the government, stakeholders and consumers for a successful transition to digital broadcasting is still low. This article focuses on Digital Broadcasting in Nigeria: What is it and what is needed to be put in place for a successful takeoff.

Abstract:
High quality of service is a paramount concern in wireless networks. One of the strategies in achieving optimal performance is to use wireless empirical models to predict wireless link quality factors such as path loss and the received power in any given transmission domain with irregular terrain. The primary goal of this study is to develop a radio wave propagation model for Uyo metropolis. An assessment was carried out in three major roads within the city of Uyo in Akwa Ibom State, to determine the quality of GSM signal reception by measuring the signal field strength, magnetic field strength, and power density of the base transceiver stations. The measurements were carried out using radio frequency electromagnetic field strength meter over a distance of 2000 meters from the base stations. The results of the measurements were analysed and a path loss model was developed for Uyo using linear regression model. Three empirical models: Okumura-Hata model, COST-Hata model, and Egli model were also applied in predicting the path loss in Uyo and the results obtained were compared with the developed model for Uyo metropolis. The comparison showed that Route D model had a better comparison factor with the developed model while the Okumura-Hata and COST-Hata were almost the same with more loss as the distance increased. In all the measurements, the standard deviation was between 3.31 dB and 3.36 dB.

Abstract:
Ologe and Badagry Lagoons are important tropical lagoons in Lagos, Nigeria. The water quality and heavy metal concentration were studied for a period of 2 years (Aug. 2016 to Jul. 2018) using standard methods. The least temperature obtained was 28.70±0.05 °C in Ologe Lagoon during the wet season and the maximum recorded was 29.41±0.08 in in Badagry Lagoon during the dry season. During the wet season (May- October) the temperature was steady and similar between the two connecting tropical lagoons. The salinity values vary at different stations in both Lagoon, 0.06 to 0.44 % in Ologe Lagoon and 0.08 to 0.28 % in Badagry Lagoon. Badagry Lagoon showed significant higher values in conductivity, total dissolved solid, chemical oxygen demand, biological oxygen demand, total suspended solid and total hardness across seasons. Heavy metal results showed that except for lead (0.25±0.10 mg/L), Ologe Lagoon had higher concentrations of all examined heavy metals (Zinc, copper, iron, chromium, lead, cadmium, manganese and cobalt) than Badagry Lagoon across season. Furthermore, cadmium, manganese and cobalt were not detected in Badagry Lagoon across season. The two studied connecting Lagoons especially Ologe Lagoon is exposed to dramatic deterioration in its water quality due to different wastes that discharge into the water body. These lagoons are clearly polluted by metals for various utilizations. As a result, the study suggests enforcing the controls on waste discharged into lagoons.

Abstract:
Geoclimatic factor variable is one of the most important radio climatic variables in the planning of the radio links in any region. A fade margin that takes into account multipath fading has to be incorporated in the link budget in the design of terrestrial line of sight communication system. This work involves the determination of the refractivity gradient over the first 100 m above ground level in Nigeria and by using the determined refractivity gradient, the geo-climatic factor (K) was calculated for typical links in Nigeria. The Geo-climatic factor (K) for the six major cities representing each geopolitical zone in Nigeria is determined in-order to improve future planning of the radio links in the regions. Measurement of meteorological parameters for five years taken in Ikeja, Lagos (Latitude 6º27´11´´N, Longitude 3º23´44´´E), Enugu (Latitude 6º27´35.8704´´N, Longitude 7º32´56.2164´´E), Kaduna (Latitude 10º31´23´´N, Longitude 7º26´25´´E), Port Harcourt (Latitude 4º47´21´´N, Longitude 6º59´54´´E), Kano (Latitude 12º3’N,Longitude 8º32´N) and Abuja (Latitude 9º10´32´´N Longitude 7º10´50´´E) were employed to estimate the country value of K. The pressure, P(hPa), temperature, T(ºC) and the relative humidity, (%), for the six location used were taken for a period of five years (2011-2015). The value of humidity were converted to water vapour pressure, e(hPa). In processing of the data, the average values of each month collected over a period of five years was used. The monthly data was used to calculate the values of the refractivity at the ground level and at 100 m altitude. From the calculated values of refractivity,the values of the refractivity gradient of heights of 65 m and at 100 m was computed and thereafter the geo-climatic factor (K) was calculated for the six geopolitical region of the country.

Abstract:
This study was carried out in Shall and Yalwa village areas of Tafawa Balewa and Dass local government areas, respectively, in Bauchi state (Nigeria) with a strong view of determining the efficacy of media in education towards managing girl child issues in Nigeria. An intensive oral interview was employed in data collection from staff of Radio Nigeria Globe FM, as well as the students and staff of schools and the parents from both Shall and Yalwa villages. The study employed a survey design and utilized a documentary approach to obtain data. Descriptive statistics (means, frequency and percentages) and χ2were used in analysing the socio-economic characteristics of the stakeholders in girl child education. The results revealed that 91.2% of the responses hold the opinion that the strategies used by the Radio Nigeria GlobeFM to intervene in girl child education proffered unique and far-reaching benefits in educating the girl child to discover herself and associate with the right group of people, marry the right kind of men, make the right contributions and help men develop sustainable environment. The results also revealed that 61.8% of the responses hold the belief that Radio Nigeria GlobeFM programmes on the Nigerian girl child are much effective, educative and relevance. The study suggested that the adoption of educational technology strategies is a way forward to managing girl child education, which is a progressive approach in Nigeria, there by setting up booster stations and organise village rallies, discussion programmes with women as moderators to serve as role models for young girls, radio links programme to initiates talks with parents and other stakeholders, initiate kiddies programme fashioned after the likes of the world of children and finally strategies for career guidance.

Abstract:
An investigation was made from April to September 2018 to detect some metals (cadmium, chromium, copper, iron, lead and zinc) in the fishes like Kribia nana, Chrysichthys filamentosus and Pegusa lascaris, as well as in water and sediment from three creeks i.e. Badagry (Station 1), Tomaro (Station 2) and Ajegunle (Station 3) in Lagos, Nigeria. Samples were collected and analyzed according to standard methods. Most of the water quality parameters are within standard recommended limits. Iron content in C. filamentosus (11.57±2.50mg/kg) from station 3 was higher (p<0.05) than iron content from station 2 (6.54±2.88mg/kg), while iron content in K. nana (8.34±1.10mg/kg) from station 3 was higher (p<0.05) than that from station 1 (6.12±1.04mg/kg) and station 2 (3.62±1.14mg/kg) respectively. Zinc (5.54±1.12mg/kg) recorded from station 3 was significantly (p<0.05) higher than that from station 2 (2.45±0.96mg/kg) and station 1 (3.84±0.86mg/kg). Iron content in all the fishes, cadmium in C. filamentosus and lead, chromium, copper in K. nana in stations 1 and 3 exceeded permissible limits. Condition factor (K) of most fish species was greater than 1. The Hazardous Index (HI) content in C. filamentosus from the three creeks and K. nana from stations 1 and 3 was above 1. Ecological risk factor(Er), enrichment factors (EF) and Index of geo-accumulation indicated moderate contamination of the sediment with cadmium. In conclusion, the three creeks are moderately polluted with metals but consumption of large quantity of the fish species could have high health risk. Hence, discharge of untreated metals into the water should be precluded.

Objectives. The study was to assess the level of knowledge of, perception of, and attitude towards uterine fibroids among women diagnosed with the condition.Methods. It is a cross-sectional descriptive study carried out among women diagnosed as having uterine fibroids in two gynaecological clinics in Lagos, Nigeria. Eligible women were recruited and a structured interviewer-administered questionnaire was used to collect the required information. Statistical analysis of data was done using EPI Info 2008.Results. Knowledge of fibroids was reported in 98.6% of the respondents and the information on uterine fibroids was obtained from radio, parents/relatives, health workers, and television in 29%, 27.3%, 18.7%, and 18.3%, respectively, by the respondents. Most of the women believed that being black, being nulliparous, or having positive family history predisposes women to having uterine fibroids. Up to 69.0% of the respondents believed that fibroid is a spiritual problem and many thought it requires spiritual healing. Fear of complications of surgery keeps most sufferers away from the hospital until fibroids become advanced or associated with complications.Conclusion. Awareness of uterine fibroids is high, but correct knowledge on aetiology and proper treatment is low. Intensive enlightenment of the populace using the mass media by trained personnel is recommended.

Abstract:
Abstract Previous studies on media coverage of health issues hardly recognize the role of time in moderating media contents. Instead, scholars most often examine how news media report health issues. In this study, we recognized the role of time by taking into account how media report differs based on when a global outbreak is confirmed in a country and when it is not. We focused on coronavirus disease 2019 (COVID-19) and examined six media—two TV stations, two newspapers and two radio stations. We content-analysed 537 stories and found that there were few stories about the virus before it was confirmed in Nigeria. But as soon as Nigeria recorded a confirmed case, the number of stories tripled. We also noticed that story format and recommendation on health behaviour were also closely linked to the COVID-19 status of Nigeria. However, we did not find an association between Nigeria’s COVID-19 status and policy recommendation among the media studied. Therefore, this study concludes that Nigerian media did not provide sufficient health warning messages on COVID-19 before its spread to the country.

Abstract:
A contextual approach to Light-Rail Transport (LRT) needs to be tailored towards specific contexts, in terms of situations or contingencies, such as socio-economic and environmental factors. This research intends to discuss the societal benefits comprised of well-informed contextual factors for policymakers and urban transport authorities, to enable them to be able to formulate objective policies for a city’s socio-economic development. The aim of this article is to analyze the contextual factors in three cities which are responsible for the contextualization of infrastructural innovations of urban light-rail transport from China. The methodology that has been used is a qualitative method using multiple case studies, which includes a pilot and semi-structured interview. The analysis compares the similarities and differences within Nigeria, and between Nigeria and Ethiopia. The most perceptible contextual factors which influence infrastructural innovations in Nigeria include an electric energy supply, modernization of LRT and their stations, Transit-Oriented Development (TOD), and seamless integration of LRT with other transport modes. The most conspicuous factors in Ethiopia are emergency ticket shops, seamless integration of LRT with other transport modes, and Non-Motorized Transport (NMT). Nigeria and Ethiopia both share the seamless integration of LRT with other transport modes. Therefore, academically analyzing contextual factors helps to unravel the poly-contextualization and context-specific decision-making processes in LRT implementation.

Abstract:
The phytoplankton diversity, pigment, abundance and distribution in relation to physico-chemical parameters were studied from four stations for a period of five months (May – September 2018) and were analysed using standard procedures. Rainfall was highest (329.5 mm) in September and lowest (142.7 mm) in July. The total suspended solid (TSS) had a mean value of 63.10±12.81 mg/L and the total dissolved solids (TDS) had the highest value of 15189 mg/L in May which was not significantly different around the sampling points {P > 0.05}. The pH and nitrate level recorded had a mean value of 7.25±0.33 and 3.11±1.33 mg/L respectively. Microscopic identification revealed a total of 129 species belonging to 62 genera, 22 families and five divisions in the following order of specie abundance: Bacillariophyceae (65 taxa) > Cyanophyceae (27 taxa) > Chlorophyta (20 taxa) > Dinophyceae (10 taxa) > Euglenophyceae (7 taxa). The high dominance of Microcystis aeruginosa observed was indicative of organic pollution. The range of community structure indices were as follows: Margalef Index (0.1406 – 5.295) and Shannon – Weiner Index (0.02644 - 0.4979). The relatively high nutrient status favours the high abundance of phytoplankton which is understood to be deleterious to the ecosystem. Municipal wastes must be treated or recycled before discharge and a continuous environmental surveillance is required to maintain the biological integrity of this area.

Abstract:
Purpose The introduction of mobile telecommunication services in Nigeria led to the development of base transceiver stations (BTS) across the country. Inadequate power supply from the national grid has led to massive use of diesel-fueled back-up generators (BUGs). The purpose of this paper is to attempt to quantify and inform relevant stakeholders about air quality implications of BTS BUGs. Design/methodology/approach Seven major telecommunication network operators were identified. Emission factor approach was used to estimate the quantity of important air pollutants such as NOx, CO, SO2, PM10, PM2.5, PAH and TVOC that are emitted from the use of the BUGs based on fuel consumption rate and generators’ capacity. Fuel-based emission inventory and emission factor from the United States Environmental Protection Agency AP-42 and National Pollution Inventory were used to estimate pollutants emission from diesel-powered generators used in the BTS sites and amount of diesel consumed. Land distribution and per capita dose of the estimated pollutants load were calculated. Findings The study showed that the deployment of BUGs will lead to increase emissions of these air pollutants. The states that are most affected are Lagos, Kano and Oyo, Katsina and Akwa Ibom states with respective total air pollutants contribution of 9,539.61, 9,445.34, 8,276.46, 7,805.14 and 7,220.70 tonnes/yr. Originality/value This study has estimated pollutant emissions from the use of diesel-fueled BUGs in mobile telecommunications BTS sites in Nigeria. The data obtained could assist in policy making.

Radio propagation measurement were acquired at the 900 MHz and 1800 MHz frequency bands from six (6) live base stations (BS1 to BS6) in Kaduna town, Nigeria using an Asus Zenfone enhanced with a network monitoring software (Network Cell Info Lite). The receive signal strength (RSS) measurements were taken from the BSs at a distances of 200 m apart (in dB) until the signal faded out and the measurements were taken for twelve (12) calendar months which covered all seasons of the year, the corresponding path loss were calculated which were subsequently used to develop a propagation path loss prediction model with the Group Method of Data Handling (GMDH) algorithm. However, the results obtained shows very small variations between the model fit (which was the best fit curve from the measured data) and the predictions (which is the forecast). Hence, since the variations between the model fit and the predictions are not wide, with sometime the values of prediction being better than that model fit, the GMDH model is showing good prediction for Kaduna metropolis.

Abstract:
Breast cancer is a major disease in Nigeria; in 2012, 27,304 new occurrences were diagnosed, and the number of mortalities was 13,960. Greater than 70% of patients present with advanced disease, which has a poor survival outcome. The mortality rates are high mainly because of a lack of awareness about breast health, screening guidelines, and treatment centers, and because of sociocultural barriers. In Nigeria, health care professionals remain the backbone for the provision of medical information to the public. This is a study of the innovative ways that breast health and cancer awareness were promoted across communities and institutions in Lagos State, Nigeria, in 2015. Several community awareness campaigns were carried out in the forms of health talks, breast cancer screenings, radio and television interviews, and campaigns on social media. Anomalies noticed during the screenings were promptly referred to appropriate hospitals for additional treatment. The campaign culminated in the #12KLLP, or 12,000 people light Lagos pink, which was a Guinness World Record attempt for the largest human awareness ribbon formed for breast cancer. There was a total reach of 28,774,812 people across platforms: 285,318 were on social media, 3,620 were in communities, 7,466,276 were on the website, 20 million were through media events, 12,000 were through publications, 7,598 were verified participants at the Guinness World Record, and approximately 1 million were through blogs. Eighty partnerships were made with various private and government institutions to facilitate different aspects of the campaign. The community members were able to learn about the need for early detection and awareness; volunteerism and corporate social responsibility were promoted among individuals and corporate institutions.

Abstract:
Responding to the international call for strategic information to understand viral hepatitis, this study investigated the health communication practice on hepatitis B virus in Southwest Nigeria. Existing studies on HBV in Nigeria have primarily concentrated on health practitioners and their patients while neglecting detailed empirical data on semiurban and urban demographic information. This study examines health communication channels as predictors of knowledge, attitude, and behavioural practices with an emphasis on three Southwest states (Lagos, Oyo, and Ogun) in Nigeria that have the highest prevalence rate of HBV. Data were gathered through a survey from a total of 600 respondents of Southwest Nigeria randomly selected through the multistage sampling technique. The hypotheses were tested with the use of multiple regression. The result reveals that health communication channels for hepatitis B virus management had a significant influence on knowledge (F = 12.708, Df = 581, P < 0.05 , Sig. at 0.000), attitude (F = 3.430, Df = 581, P < 0.05 , Sig. at 0.000), and preventive practices (F = 11.075, Df = 581, P < 0.05 , Sig. at 0.000) of residents of Southwest Nigeria, respectively. The study concludes that health communication channels such as the television, Internet, radio, newspaper, and health workers positively influence the behavioural practices of residents of Southwest Nigeria. The study recommends the development of a nationwide communication system on HBV targeted at putting an end to the disease in line with the 2030 global elimination objective of Sustainable Development Goal 3.

Abstract:
2015, 2016 and 2017 have been confirmed the three warmest years on record and the degree of warming during these three years has been exceptional. Extremes of heat and cold environmental conditions have been known to be very detrimental to the health and comfort of humans. The severity of these adverse effects is often local and varies from one place to another though they are happening on a global scale therefore Temperature variation, Heat Index (HI) temperature and Dew Point Temperature (DPT) ( Meteorological comfort indices) were used to assess the effect of this condition in southwest, Nigeria. Air temperature and Humidity data were collected from meteorological stations situated in the southwestern states selected for study and was processed using the rule of Thumb for DPT calculations and Steadman (1979) formula simplified by Rothfusz’ model (1990) for HI temperature. The data analysis was done using Microsoft Excel Package and Statistical Package for the Social Sciences (SPSS), the following results were obtained: Elevation may affect temperature yet during extreme warmness other factors can have a greater influence on temperature and meteorological comfort indices used to assess extreme warmness in southwest Nigeria from this study showed greater impacts thus: Heat Index Temperature has highest values in Lagos State, while Dew Point Temperature have highest values in Ogun state. None of these extreme warmness measuring variables seem to be solely in favour of state Location in terms of coordinates and elevation; this suggests more anthropogenic influence forming the characteristics of the states to geographic locations of the states however, between the start year of extreme warmness (2015) and 2017, HI temperature showed a significant increase while average DPT did not really change during the period of extreme warmness.

Abstract:
Indiscriminate disposal of solid waste pollutes the environment and poses a health risk to the public. This study therefore examined the attitude and pattern of solid waste management practices among the residents of Oshodi-Isolo Local Government area, Lagos State. The study employed a descriptive cross-sectional design. A Multi-stage sampling technique was used to select 600 respondents for the study. A validated semi-structured interviewer administered questionnaire was used for data collection. Descriptive and inferential statistics were conducted to give statistical responses to the research questions and hypotheses using SPSS version 23. The mean age of respondents was 38.28±12.48years. More than half (51%) of the respondents were male. Majority (91%) of the respondents had positive attitude towards solid waste management. More (61.8%) of the respondents’ reported that they had waste bins in their houses. Less than half 247(41.2%) of the respondents did not separate their wet and dry waste before they disposal. Few (15.8%) of the respondents’ burned their waste. There is a significant relationship between resident’s attitude (r =0.14, p=0.00) and their solid waste disposal practice. Most of the respondents had a positive attitude towards proper waste management and poor practice of solid waste management. It is recommended that the government through the federal and state ministries of Health and Environment should create awareness via seminars, radio, televisions, and social media to teach best practices in waste management.

Abstract:
The telecommunication technologies deployed in the last decades have shown that there are better days ahead. From electric telegraphs systems in the 19th century to today’s wireless communication using satellites and land links (Lanzerotti, 2001). The horizontal component (H-field) of the geomagnetic field has great impacts in the present-day communication technologies. The aim of this paper was to analyse the daily hourly departures of geomagnetic H-field along the low-latitude stations on the equatorial chain in relation to their correlation coefficients with their longitudes. The magnitude of H-component is a very significant factor in the determination of the total magnetic field of any location on the earth. The baseline values (H0) which is the average of H components at 23LT, 24LT, 1LT and 2LT were subtracted from the hourly values of H (Ht) to obtain the hourly departures of H (dH). The hourly departures of H (dH) from the baseline is non-cyclic since H1 ≠ H24 as observed over the three MAGDAS stations in Nigeria. The correlation coefficients between dHs of Lagos/Ilorin, Ilorin/Abuja and Abuja/Ilorin are 0.97, 0.75 and 0.66 respectively. This suggests that substorms are deflected eastwards along different longitudes due to the rotation of the earth such that locations in the same longitudes have the same hourly departures. There is no solar radiation during the nighttime, thus dH should be zero but for the energy stored in the magnetotail, the reduction of hourly departures towards nighttime in Nigeria is evident. This is further revealed as the midnight dH amplitudes decrease regularly. The eastward motion of the electrons during substorms was suggested to be responsible for the reduction of the H-field at the nightside magnetotail region for all the stations. These findings will assist the telecommunication companies to know which location is best for their transmitters to be sited in order to reduce loss of signals along the optical cables to the receivers. Furthermore, global telecomms companies should have business continuity plan which should include risk assessment and prompt response to geomagnetic disturbances being one of the causes for telecommunication outages.

Abstract:
Fast Moving Consumer Goods are products that are required by almost all users in their day today life. The advertisements for these products need more attention in terms of creating responsiveness among the consumers for their purchase decision. However, consumers are bombarded with lots of information through multiple media like newspapers, magazines and internet but remain engaged from time to time hence lack time to update themselves. This has made it difficult for advertisers to trap consumers hence resort to outdoor messages to reach the target people. Extant studies on the out of home advertising have attempted to elucidate on the challenges of advertising and the attendant supposed solutions, conversely, most of the extant research focus more on developed countries than developing countries such as Nigeria. Hence, this study examined the effect of Out-of-Home Advertising on consumer buying behaviour of selected fast moving consumer goods in Lagos State, Nigeria. Survey research design was adopted for the study. The population of the study consists of individuals living in Lagos State with total number of 2,556,300 and with the sample size of 520 derived from Taro Yamane method. Data was collected using self – administered structured questionnaire and validated for a response rate of 93.4%. Cronbach Alpha reliability for major constructs had an average of 0.80. Random sampling technique was used. The data collected was analysed using simple linear regression. Findings revealed that there is a strong positive and significant relationship between Out-of-Home Advertising and consumer buying behaviour(β= 0.834; R2= 0.695; t(520) = 33.225; p>0.05). The study concludes that Out-of-Home Advertising has significant and positive effect on consumer buying behaviour and recommends that the study findings led to the recommendations that producers of fast moving consumer goods should focus more on out of home advertising such as use of billboards as opposed to other forms of media like T.V and Radio to help boost consumption and sale of their products. The study also recommends marketers of FMCGs to enhance the knowledge and awareness of consumers with regard to existence and location of billboards.
