Patterns of diarrhoeal diseases in under-five children in Emekuku: A hospital-based study
(Federal University of Technology, Owerri, 2014-04) Njoku, Chinonyerem John
This study was undertaken to determine the patterns of diarrhoeal diseases in under-5 children and the associated risk factors in Emekuku, Imo State, Nigeria. A matched pair case control study design with strict inclusion and exclusion criteria was adopted. Cases were children with loose watery feces, pathologically diagnosed with diarrhoea by the physician. Each case was captured immediately after diagnosis by the physician and administered with the questionnaire. Controls were children diagnosed of any other disease other than diarrhoea. Both cases and controls were appropriately matched in terms of age, sex, and other determinants and enrolled from the outpatient and children’s wards of the Hospital. A total of 176 under-5 children were enrolled with 88 cases and 88 controls. The results showed that most cases of diarrhoea observed were acute (93.2%), while persistent diarrhoea accounted for 6.8%. Ninety five percent (95%) of diarrhoeal cases were watery, with mean number of stools/child/day being 4.3 times (SD 1.92). Of the 17 exposure variables analyzed, only age (6-11 month); breast feeding (complementary feeding) (P<0.001); birth weight, maternal employment (unemployed women); toilet type (pit toilet); hand washing with water only (P<0.001); use of rain water and crowding index were significantly associated with diarrhoeal disease occurrence observed in this studied. The study shows that diarrhoeal diseases are still prevalent in this area. Interventions on exclusive breast feeding, provision of improved toilet type, and education on appropriate hand washing methods and improved sanitation should be intensified.
An efficient predictive model for choosing mobile cellular service provider in Nigeria
(Federal University of Technology, Owerri, 2015-07) Ohuabunwa, Augustine Ebere
Free competition and new network technology have increased competition and widened the range of network service available throughout the world. However, for cellular network service providers, loyalty is a rare trait among customers when it comes to choosing a particular mobile cellular system provider. Despite the huge financial commitment by companies into their respective communication technologies, users ultimately make decisions based on their perceived quality of service (QoS). This thesis attempts to identify the factors affecting the Quality of Service of cellular mobile network providers in Nigeria and put their effect in quantifiable terms using four leading telecommunication firms viz. MTN-Nigeria, Globacom, Etisalat and Airtel. With a clear choice of information sources, regressional analysis and SPSS was utilized. It was discovered that six factors affect the quality of service of cellular mobile network: Network coverage/ Availability of service(X5), Call quality(X3), Price of service (X4) , Customer care(X2), Diversity of bundle option of service (X1) and Promotion/Offering of Incentive(X6). A predictive model was derived as : Y = 3.731+0.565X5 + 0.440X3 + 0.221X2+ 0.189X4 + 0.165X1 + 0.097X6.The significance of the factors X4, X1 , X2 and X6 depend on X5 and X3, hence Y = 3.731(1+0.1514 X5+0.1179 X3).
Impact of oil spillage on physicochemical quality parameters of Abonema creek water
(Federal University of Technology, Owerri, 2014-11) Onwuagba, Chinwe Grace
The current study investigated the impact of oil spillage on Physicochemical Quality parameters of Abonema creek water. Water sample was collected with a container from 3 different locations which included the control site. The samples were subjected to standard physicochemical analysis. Among other parameters analysed, conductivity(µs/cm2) (22000 – 29600),TDS (mg/L) (15400 – 20720), total petroleum hydrocarbon (mg/L) (0.001-1246.6) SO4-2(mg/L) (350 –510),Cl-(mg/L) (6900-8900), Pb2+(0.014 – 0.266 ), and alkalinity (mg/L) (65 – 75), where all above recommended WHO standard. This implies that the river is polluted by the discharge of effluent from petroleum exploration activities. Water sample from the affected site was more higher than that of the control. Companies should not wait until a spill is out of hand before a cleanup intervention; timely cleanup exercise should be encouraged.
Assessment of women participation in fish valued chain acivities in Buguma area of Rivers state, Nigeria
(U. P., 2016) Ogolo, I. G. S.; Ogueri, E.; Adesope, O. M.
The study focused on the assessment of women participation in fish value chain in Buguma community, Asari-Toru local Government Area of Rivers state. Data were obtained from 56 women in the study area. Descriptive statistics such as frequency, percentage and mean were used to analyse the data collected from the study. Findings revealed that 44.7% of the women are within the age range of 40-49 years, which makes them still energetic to actively participate in the fish value chain. Majority of the women had formal education with 42.9% with a mean household of size of 6-10 persons. Majority of the respondents are in a cooperative society 71.4%, about 55.3% have a farming experience of 10 years and above. Extension agents visit the study area with about 98.8% respondents. The average annual income gotten by the women was about N20,000. Stages involved in the fish value chain in the study area includes capture of fish, handling and sorting, processing, storage, marketing, advertising, distribution. The women are actively involved in each of the chain. It was noted that women have a high level of participation in fish value chain in Buguma community (89.3%). The problems faced by these women includes lack of modern facilities, lack of fund, insufficient wood fuel, lack of harvesting equipment’s, technical know-how of modern facilities and poor storage facilities with 98.8% respondents agreeing to it. Despite the participation of the women in fish value chain, they were hardly given attention by the extension agents who visited the study area
Sequence stratigraphic interpretation of wells 1,2,3 & 4 in the "GERA" field, Greater Ughelli Depobelt, Niger Delta Basin, Nigeria
(Federal University of Technology, Owerri, 2014-02) Onwualu, Nneka Emelda
A sequence stratigraphic approach was employed to understand sediments penetrated in Gera Field situated in the Greater Ughelli Depobelt, Central Niger Delta Basin. The technique incorporates biostratigraphic and well log data in constructing a high resolution sequence stratigraphic framework for the field. The analysis of the above data sets enabled the subdivision of the transverse part of the stratigraphic column within the field into sequences and system tracts. Four 3rd order Maximum Flooding Surfaces (MFS) and their intervening sequence boundaries (SB) were interpreted in the area. Three depositional sequences were interpreted within the field and were subdivided into transgressive systems tract and highstand systems tract. Four maximum flooding surfaces correlate with the 28.1Ma, 31.3Ma, 33.0Ma and 34.0Ma of the transgressive marker shales of the Niger Delta Chronostratigraphic Chart. The 28.1 million years (Ma) MFS (G. Opima Opima) with its distinct log signature, constitutes the regional seal rock while the different sequence boundaries act as excellent reservoirs of the field. Of the four sequence boundaries, only one was found to be truly Type-1 sequence boundary, while the other three could not be convincingly attributed to a Type-1 sequence boundary, since a lowstand systems tract does not overlie them. The age of sediments penetrated in Gera field is found to range from Early – Late Oligocene as deduced from the foram zonations of wells in the field.
