Abstract: Healthy ageing is a lifelong process optimizing opportunities for improving and preserving health and physical, social and mental wellness, independence, quality of life and enhancing successful life-course transition. In Sub-Saharan Africa, it is estimated that the number of elderly persons will rise from about 37.1 million in 2005 to 155.4 million in 2050. The elderly population in Nigeria is estimated at 4 percent and is expected to triple by the year 2020. The increasing number of the older population will increase the burden on the health resources. The objective of this study was to evaluate the determinants of healthy ageing among rural elderly in northern Nigeria in order to promote those that have positive correlation with healthy aging. A cross sectional descriptive study was conducted among 1600 rural elderly aged ≥60 years using interviewer administered semi-structured questionnaire between June and July, 2011. Majority (53.8%) are 60 - 64 years, 24.6% >69 years, 72.4% are males while most are Muslims (85.6%) and 81. 4% are still married. Most are farmers (48.9%) while 73.6% have no formal education. 85.3% earn less than $100 monthly while 47.6% have no income. 93.5% do not take alcohol, 92.1% do not smoke and 89.8% are physically active. 83.1% have normal blood pressure (on examination), 88.3% normal blood glucose level (on examination). Diet, no smoking, high physical activity and adequate sleep are positively correlated with healthy aging (p < 0.05). Good health practices and family support should be sustained while special care for the aged should be established by the government.

Abstract:

Cervical cancer is the leading cancer-related cause of death among women in Nigeria. An estimated 70,700 new cases occur each year, representing one quarter of all female cancers in sub Saharan Africa. The magnitude of the problem has been under recognised and under prioritised compared with the competing health priorities of infectious diseases such as HIV/ AIDS, tuberculosis and malaria. Studies in the United States and Nigeria have indicated that the disease has the highest incidence among the lowest socio-economic groups especially residing in rural areas. The peak age for the disease has been shown to be within 35-45 years age group. Knowledge of the risk factors of the disease is deemed important in its early detection and prevention. The objective of this study was to assess the knowledge, attitude and practice of rural women with cancer of the cervix. A cross sectional descriptive study was conducted among 1600 rural women aged 15-55 years (randomly selected from 28 villages) who were interviewed using a structured questionnaire between April and June, 2010. The majority (82.2%) were married before the age of 20 years and 19.3% before 15 years, 40% in polygamous union, 22.6% have had 2 or more sexual partners, 71.3% were primi and grand multiparous, 7.5% have had previous treatment for STIs and 10.1% were on various types of contraceptive. 454 (28.4%) have heard of Ca cervix, 358 (22.4%) knew the location of the cervix. 2.3% had Pap smear test of which 72.6% were within 2 years. The majority (89.9%) will avail themselves for screening.

Abstract: Objectives To describe the variation in household crowding and social mixing patterns in the African meningitis belt and to assess any association with self-reported recent respiratory symptoms. Methods In 2010, the African Meningococcal Carriage Consortium (MenAfriCar) conducted cross-sectional surveys in urban and rural areas of seven countries. The number of household members, rooms per household, attendance at social gatherings and meeting places were recorded. Associations with self-reported recent respiratory symptoms were analysed by univariate and multivariate regression models. Results The geometric mean people per room ranged from 1.9 to 2.8 between Ghana and Ethiopia respectively. Attendance at different types of social gatherings was variable by country, ranging from 0.5 to 1.5 per week. Those who attended 3 or more different types of social gatherings a week (frequent mixers) were more likely to be older, male (OR 1.27, p<0.001) and live in urban areas (OR 1.45, p<0.001). Frequent mixing and young age, but not increased household crowding, were associated with higher odds of self-reported respiratory symptoms (aOR 2.2, p<0.001 and OR 2.8, p<0.001 respectively). A limitation is that we did not measure school and workplace attendance. Conclusion There are substantial variations in household crowding and social mixing patterns across the African meningitis belt. This study finds a clear association between age, increased social mixing and respiratory symptoms. It lays the foundation for designing and implementing more detailed studies of social contact patterns in this region.
Considering Fading Effects for Vertical Handover in Heterogenous Wireless Networks

Computer Science , 2014,
Abstract: Over the years, vertical handover has attracted the interest of numerous researchers. Despite the attractive benefits of integrating different wireless platforms, mobile users are confronted with the issue of detrimental handover. As a mobile node (MN) moves within a heterogeneous environment, satisfactory quality of service (QoS) is desired by ensuring efficient vertical handover. This demands not only the efficient execution of vertical handover, but also optimized pre-handover decisions, such as: handover necessity estimation (HNE), handover triggering condition estimation (HTCE) and handover target selection (HTS). The existing works on HNE and HTCE optimization considered the coverage region of a point of attachment to be circular, ignoring the fading effect. This paper considers the effect of shadow fading and used extensive geometric and probability analysis in modelling the coverage area of a WLAN cell. Thus, presents a realistic and novel model with an attempt to ensure optimal handover as a mobile node (MN) traverses a heterogeneous wireless environment. Monte-Carlo simulations were carried out to show the behavior of the proposed models. Results were validated by comparing the proposed models with existing works.

Abstract:


Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier scheme used in modern broadband wireless communication systems to transmit data over a number of orthogonal subcarriers. When transmitted signals arrive at the receiver by more than one path of different length, the received signals are staggered in time; this is multipath propagation. To mitigate the effect of dispersed channel distortion caused by random channel delay spread, Cyclic Prefix (CP) is introduced to eliminate Inter-Symbol Interference (ISI). In the literature, researchers have focused on carrying out investigations (or studies) mainly on the two existing CP insertions, namely: normal and extended CPs. Both CPs have limitations with respect to handling channel delay spreads. In the current work, a new CP, herein referred to as “ultra extended” CP is proposed to address delay spreads beyond the limits of the normal and extended CPs. The efficacy of the proposed ultra extended CP is tested via simulation under different scenarios. It is shown by the results obtained that the proposed CP can efficiently handle delay spreads beyond the limits of the existing normal and extended CP, and can indeed be implemented in the design of future telecommunication systems to accommodate higher channel delay spreads and it ensures wider cell coverage.

Abstract:

Medium Access Control (MAC) protocol consists of sets of rules that determine which node is allowed to access the transmission medium. It provides mechanism for collision avoidance such that interfering sensor nodes do not transmit at the same time. In the literature, researchers have proposed different MAC protocols with features aimed at improving energy efficiency and thereby prolonging the life of sensor nodes. Sensor MAC, Time-out MAC (T-MAC), Dynamic Sensor MAC (DSMAC), WiseMAC, Quorum-based MAC (Queen-MAC) and Traffic Adaptive Medium Access Protocol (TRAMA) are some examples of proposed MAC protocols. There is a duration field in each transmitted packet. The value of this field indicates how long it will take to complete the remaining packet transmission. In the current paper, a novel energy-efficient MAC protocol is proposed based on the use of duration value in transmitted packets to setup varying sleep/wake-up schedules for neighbouring nodes of the receiver. The effectiveness of this proposed Packet-Duration-Value-based MAC (PDV-MAC) protocol is tested via Simulation which is implemented in Visual C# and MATLAB. It is shown by the results obtained that the proposed MAC protocol can indeed be implemented in sensor nodes to improve energy efficiency in wireless sensor network.

Computer Science , 2014,
Abstract: Over the years, vertical handover necessity estimation has attracted the interest of numerous researchers. Despite the attractive benefits of integrating different wireless platforms, mobile users are confronted with the issue of detrimental handover. This paper used extensive geometric and probability analysis in modelling the coverage area of a WLAN cell. Thus, presents a realistic and novel model with an attempt to minimize unnecessary handover and handover failure of a mobile node (MN) traversing the WLAN cell from a third generation (3G) network. The dwell time is estimated along with the threshold values to ensure an optimal handover decision by the MN, while the probability of unnecessary handover and handover failure are kept within tolerable bounds. Monte-Carlo simulations were carried out to show the behavior of the proposed model. Results were validated by comparing this model with existing models for unnecessary handover minimization.

Abstract: Farm Practical programme addresses the short comings in curricular of agricultural graduates enabling them to acquire knowledge and practical skills needed to become proficient in agriculture. The study contributes in providing insights into perceptions of level 400 agricultural students regarding the Farm Practical Year (FPY) programme at the University of Agriculture, Abeokuta, Nigeria. A total of 261 sample students were selected through stratified sampling procedure from 11 core agricultural departments and administered with pre-tested questionnaire. Results show that the programme provided students with ‘hands-on’ experience and opportunity to apply theory learnt in classroom to a real-life fi eld situation in which students had to adapt and solve problems on daily basis. Students also felt strongly that the farm practical would contribute to their professional career and employability on graduation. However, certain perceived problems were raised by students such as lack of on-campus accommodation, delay in payment of allowances and paucity of resources. It is recommended that greater efforts are needed to mentor students to take active interest in farm practical while human and material resources strengthened to deliver this mandate.
