- Youths constitute a vibrant, critical resource input in the development process of any nation. It is, therefore, imperative that their health and wellbeing be safeguarded in the pursuit and sustenance of the socio-economic transformation of any society. With the unabated high prevalence of HIV and AIDS among this age cohort, communication campaigns must be restrategized, diversified and focused on effecting change in the behaviours that predispose young people to HIV infection. Providing youths with requisite information through social media has the potential of stemming the scourge of the virus. The paper critically examines the use of social media as a potentially veritable tool for campaigns aimed at combating the spread of HIV among Nigerian youths. 2 results 2
- "Agricultural water management system aims to provide crop water requirement to sustain optimum yield. Some of the factors influencing optimum crop yield are drainage design parameters in water logged soils. Hence, the impact of drainage design parameters on optimum crop yield was examined, field experimentation was for 12 weeks which includes land preparation, planting to maturity of Corchorus olitorius ('Ewedu') on a poorly drained sandy loam of National Horticultural Research Institute, Ibadan 'fadama' field. Hourly rainfall and daily minimum and maximum temperature data for 32 years (1963-1994) for Ibadan was obtained from Nigerian Meteorological Station as DRAINMOD input data. Aluminum drainage pipes at 110cm drain spacing, 60cm drain depth and effective radius of 5.08cm was installed. Depth from drain to restrictive layer was 204.3cm while drainage coefficient was 1.3cm/day. Drainage system parameters, such as grain spacing, drain depth, effective drain pipe radius were varied and effects on crop yield observed. Field evaluation was conducted at 60cm and 110cm drain depth and spacing respectively, and relative crop yield of 36.39% was attained at 40cm, 45cm, and 55cm drain depth, corresponding to 120cm, 115cm and 105cm spacing respectively when drain depth was varied with drain spacing at constant drain pipe effective radius it was concluded that if land availability is limiting and there is availability of cheap labour typical of developing countries drain depth of 55cm, and drain spacing of 105cm and drain pipe effective radius of 2.54cm (i.e 1 inch pipe) corresponds with the optimum yield of Corchorus olitorius. However, shorter drain spacing requires more drainage pipes and land reformation; hence increase in production cost. " 1 results 1

- Distance Learning programmes would simply become impossible tasks without information and communication technologies (ICTs) as well as internet based instructional strategies. These programmes are characterized by learner- centredness, life-long learning, independent learning and recognition of prior learning. Although, the University of Ibadan Distance Learning Centre (UIDLC) is well known for the use of ICTs, more advanced technologies are not prevalent feature of the programmes. This study therefore assessed the level of utilisation of ICTs and internet facilities in the University of Ibadan Distance Learning programmes with respect to their availability and adequacy. The Input- Process- Output evaluation model was employed to guide the study. A sample of 200 participants, selected through multistage sampling procedure was involved in the study. Three research questions guided the study. One validated instrument was used to collect data and its reliability index was 0.86. Data was analyzed using frequency counts and percentages. In terms of availability, usability and adequacy of Information and Communication Technologies: Radio programme service 147(73.5%); Overhead projector 105(52.5%); Video tapes 147(73.5%); Audio tapes 119(59.5%);Computers 145(72.5%); Internet facilities 175(87.5%) and Electronic board 118(59%) were available and in use in the programme, while Interactive television programme service 13(6.5%); Fibre optics 59(29.5%) and Electricity supply were in short supply in the programme. The distance learning institution (UIDLC) is striving to make use of ICTs and Internet facilities on its programmes. However, impact of ICTs goes wider than just the structure and presentation of courses, it must also aim at improving teaching-learning resources, staff capacity development, learner support services, and increase the number of courses available to prospective candidates in order to position distance education in Nigeria for global competitiveness. 1 results 1

- Evidence-based design (EBD) has become an acceptable paradigm in environmentbehaviour endeavours in recent years with documented benefits especially in healthcare facilities. However, little is known of its application to University Campus Open Spaces (UCOS) like University Zoological Gardens (UZGs) which accounts for the repetition of design mistakes. This study aims to assess the UZGs as a major component of UCOS in South-west Nigeria with a view to formulating EBD frameworks. It adopts a comparative post-occupancy evaluation (POE) approach through a Stratified Random Sampling protocol of users (n=3,016) of the gardens in Federal Universities in South-west Nigeria. Results of the quantitative data analyses suggest that while walk-ability is a primary satisfaction factor among thirty design considerations in the formulated model, legibility is the most primary cognitive factor for designing perceptible high quality UZGs. The study argues in favour of the developed framework as design tool-kit and recommends its application as a feedback input into the design process of UZGs 1 results 1

- Poultry is a major livestock subsector which offers the least expensive way of filling the protein gap in human nutrition. However, low productivity in poultry subsector of livestock industry and inadequate knowledge on efficiency of resource allocation have scared many interested farmers from investing fully in the enterprise. The study ascertained the determinants of poultry productivity and allocative efficiency of each of the major resource inputs in commercial poultry production in Oyo State. Primary data were collected using well structured questionnaires. A multistage sampling technique was used to sample 90 poultry farmers to represent the commercial poultry farmers in the study area. Data collected were analyzed by using descriptive statistics and production function model. The result showed 'that the poultry farmers in the study area were educated and quite experienced in poultry farming with an average of 8years. The number of birds raised, labour, feed and drugs/vaccines were found to be the most significant inputs in poultry production and thus, require special attention. Poultry production in the study area was found in stage two of production surface as indicated by Returns to Scale (RTS) of 0.798. The result further showed that flock size, labour, feed and drugs/vaccines had efficiency indices of 0.046, 0.960, 0.00095 and 0.587 respectively implying that these inputs were inefficiently allocated and utilized except labour that was close to the economic optimum. It is therefore recommended that there should be policies aimed at educating poultry farmers in the study area on efficient resource management techniques most importantly efficient administration of feeds and drugs/vaccines, adequate stocking density of flock and efficient management practices. 1 results 1

- Scheduling models based on efficient resources utilization without sufficient consideration for customer satisfaction or vice-visa is inadequate in many real-life multi-criteria scheduling problems. This work was aimed at the development of a bi-criteria algorithm for the simultaneous optimization of Makespan (Cmax) and Number of tardy jobs (NT) in a single machine problem with Sequence dependent set-up time. An existing single criterion algorithm, the Set Sequencing Algorithm, was adapted to solve the bi-criteria problem, Graphical User Interface (GUI) based software of the new algorithm was developed and its performance was evaluated with a real life problem and 150 randomly generated problems, with problem sizes ranging from between 20 and 150. The values of Crnax and NT of the solution sequences were analysed. The output sequences gave an average reduction of 32.1 0% in both measures of performance compared with the input sequences. The software was also shown to be user friendly. It is concluded that Set sequencing Algorithm is suitable for bi criteria scheduling optimization 1 results 1

- The Nigerian market for construction materials has a problem of standardization as a massive range of variation in construction materials properties plagues the market. A larger number of these variations are below the accepted standards and a key material affected is reinforcing steel. This research aims to investigate the effect of variation in physical and mechanical properties of reinforcing steel on post-construction parameters (cost and safety margins) of buildings in Nigeria. Data on variation of selected properties was collected through extensive literature review and processed into tables showing the result of the input data on key building parameters. Data visualization was done using Microsoft Excel to help gain insights on trends and patterns. The trends and patterns observed informed the regression analysis carried out with Microsoft excel, aimed at establishing relationships between variable variations. A rebar optimization algorithm/software was developed to help optimize variation in standard rebar lengths and reduce waste on site, and was tested on five (5) project cases. The results show a wide range of variation for bar diameter and yield strength values, with some values falling as much as 30% below standard. The variation in young’s modulus was seen to be minimal and has the least effect on safety margins. Equations were generated from regression to predict effect of these variations on safety margins. The rebar optimization algorithm proved efficient in reducing waste and saving cost. The algorithm follows a recursive approach for problem solving. The variation in these properties have a significant effect on building safety and cost. The prediction formulae generated can be used by Engineers to track safety margins and the algorithm can help with waste reduction and cost saving on projects. 1 results 1
