- "Radio stations have used jingles for environmental education and communication in Nigeria for decades though not much has been done to study the impact of such use—which is the purpose of this article. Through 12 focus group discussions (FGDs) in six local government areas of Oyo state, Nigeria, interviews with the program directors of two radio stations, and a questionnaire administered with 18 program producers from the stations, the researcher found that producers and directors had full confidence in the ability of the jingles to engender environmental sanctity, and that listeners fully understood the message of the jingles. However, listeners mostly did not adopt the behavior recommended by the jingles, because the government did not make the infrastructures needed to do so available or functional. Though the jingles were aired, the outcome of their use is a frustration of the listeners and even the producers. Based on the findings, the article draws five lessons for better social marketing of environmental behavior. " 1 results 1
- A biobjective model is proposed for production planning in a multi-stage, multi-facility production system. The decision situation considered was a case where the Decision Maker (DM) wants to determine the quantities of materials to be fed into each production facility at each stage of production that gives maximal realization of his objectives. A numerical example is solved using three Linear Programming procedures. The methods used are: Compromise Constraint Biobjective LP (CCBLP), Linear Combination of the Objective Functions (LCOF) and Goal Programming (GP). The behaviour of the CCBLP model shows that it is superior to LCOF and non-preemptive GP in terms of its sensitivity to relaxations in the objectives. It also supports the result of an earlier research that the CCBLP gives the real compromise solution. 1 results 1

- Although an essential but scarce resource, money is constantly required for the purchase of raw materials necessary for a continued production of livestock feeds. Improper management of available capital can lead to stoppage of production activities, low productivity and loss of customers’ good will. Therefore, there is the need to manage effectively the little capital available. This study was aimed at developing and solving a model that can determine the procurement order for raw materials considering the liquid capital constraint. An animal feed firm was investigated and data on materials (bill, quantity ratio, cost); products list; supplier’s list; product demand; liquid capital available and the available lead time amongst others were collected by means of interviews, observations and existing records. These were thereafter analysed to form the required parameters. A multi-objective optimization model was developed using linear programming technique as a tool for procurement order of materials in the firm and solved using two different soft wares (Tora 1.0 and Lingo 14.0). Selection of suppliers was based on payment term. 6 products, 13 materials, 7 suppliers, 2 days and ₦138,856 were obtained from the bill of materials, suppliers list, available lead time and liquid capital available respectively. A total weekly demand of 22,600kg of product was also obtained from the product demand. A total of 205 parameters were obtained from the analysed data. The developed model exhibited 3 objective functions (maximize profit on all products, minimize waiting time for all raw materials and minimize the total cost of raw material), 32 variables (Q1...q1) and 78 constraints (t1 ≤ 0.28… t13 ≥ 0). Same optimal values (0, 0, … and 0.55) were obtained from the use of Lingo 14.0 and Tora 1.0. Moreover, 211.97₦kg was realised as the optimum value for the objective function. The supplier IBM, with the most flexible payment term was selected to supply nine out of the 13 materials. The developed model will be useful in ensuring effective management of the available liquid capital for material procurement, thereby eliminating the stoppage of production activities, improving productivity and ensuring customers’ good will. 1 results 1

- Asides inventory cost, which is being used as the only inventory performance measure at the University of Ibadan bakery, a number of other criteria, such as inventory cost, service level, inventory turnover and delivery lead time which influence the performance of an inventory system have surfaced over the years. Hence, there is the need to examine all these criteria-objectives altogether. Therefore, this research was centred towards optimising the inventory system of University of Ibadan bakery, putting multiple criteria into consideration. Data on 17 raw materials: their costs, suppliers, usage rate, lead time, storage space and available capital were collected by means of interviews, past records and observations. The weighted goal program algorithm was adopted to find the best compromise between fulfilling the four objectives by minimising the sum of the deviation from the target values of the goals. Subsequently, Lingo 17.0 and Tora 1.0 optimisation software packages were used to solve and compare the model generated, while putting into consideration storage space constraint and budgeted capital. The developed model from the goal programming algorithm exhibited four goals (combined into one objective function). Same solutions were obtained from Lingo 17.0 and Tora 1.0. While Lingo 17.0 gave a uniform service level of 100% , a turnover ratio greater than 1(>1) for all the materials at a negligible increase (of < 0.0001%) in total inventory cost of the raw materials and available lead time duration of zero days (< 24 hours) for each material, Tora 1.0 gave a uniform service level of 100% a turnover ratio greater than 1 (> 1) for all the materials at a negligible increase (of < 0.0001%) in total inventory cost of the raw materials and available ead time duration of zero days (< 24 hours) for each material. Implementation of the developed model will eliminate unnecessary waiting time between production, thereby ensuring effective and efficient utilization of raw materials in production which will lead to reduced cost of holding inventory, elimination of unnecessary overall cost and wastages, and also improvement of the productivity and profit on the long run. 1 results 1

- Background There is abundant evidence that the first and only School Health Policy (SHPo) in Nigeria was adopted in 2006, but no study has since evaluated the quality of implementation (QoI) in government and privately funded schools. This study was conducted to evaluate the QoI of the School Health Program (SHP) in public and private primary schools of a rural Local Government Area in Oyo State using the SHPo framework as a guide. Subjects and methods A comparative-descriptive cross-sectional design was chosen. A two-stage sampling technique was used to select 46 primary schools in a rural area: 30 public and 16 private. An observational checklist was used to assess the five domains of the SHP, namely: School Health Services (SHS), Skills Based Health Education (SBHE), School Feeding Services (SFS), Healthful School Environment (HSE) and School, Home and Community Relationship (SHCR), as listed in the Nigerian SHPo framework. QoI was assessed by exploring the availability, suitability and functionality of basic provisions for SHP implementation. Results The majority of schools (90% public; 87.5%private) had first-aid boxes, but they had no contents in 23.3%of public and 68.8% of private schools. In only one private school was evidence of periodic medical inspection. A school meal service was present in 93.3%of public and 18.8%of private schools. Only one private school practiced medical screening. Some had gendersensitive toilets (81.3% private; 33.3% public). None of the schools had evidence of pre-employment medical and routine screening for non-communicable diseases for staff. Overall, around 50% of schools had poor QoI of the SHP (63.3% public; 25.0% private). Conclusion QoI of the SHP in selected rural public and private primary schools was generally poor, but with better quality in private than public schools. 1 results 1
- Background: Healthy literacy has been shown to improve health care access and adherence to Tuberculosis (TB) treatment. Still it remains largely unstudied in many high risks, underserved and low literacy African populations. This study aims to bridge the existing knowledge gap by assessing health literacy among patients with TB in a rural town in Northern Nigeria. Methodology: A cross sectional study was conducted among patients who attended the TB clinic of a secondary health care facility in Babura, Jigawa State, Nigeria between Oct 2008 and March 2009. All patients who visited the TB clinic during this period were interviewed. Result: Many (71.6%) reported having been educated about TB by a health worker, mostly on predisposing factors 43.2%, general facts (31.1%) and disease process (21.6%) but less on patient's role in disease management (1.4%). Functional health literacy was high; mean score was 7.9±0.3 out of 10. Knowledge about the disease process, diagnostic requirements and treatment regimen were the highest. However 97.3% felt drugs were no longer necessary once symptoms abated. Patient involvement in treatment decisions was also suboptimal as only 52.7% reported making a joint decision about drug “pick up” options with their physicians. Conclusion: Very high functional literacy score seemed to have been achieved among these rural low literacy TB patients even without a structured health literacy program. However patient participation in treatment seems to be underemphasized and was thus suboptimal. An important gap in patient education regarding continued TB treatment was identified and should be targeted for intervention. 1 results 1
- Background: Information and Communication Technologies (ICTs) are generally becoming prevalent in Nigerian higher institutions. Although studies have shown that utilization of ICTs has great potential of ensuring effective delivery in teaching music as well as serve as valuable complimentary resource materials in musical arts educational endeavours, not much is however known about how Nigerian musical arts educators use ICT especially the music related softwares and the individual-level factors that affect ICT use, a gap in blow ledge this study attempted to fill. Materials and Method: A questionnaire was administered to thirty-eight musical arts educators proportionally selected from ten higher institutions in Nigeria offering music with the aim of finding out levels of information technology adoption and utilization, characteristics of ICT use by lecturers, and factors which influence ICT use. Findings: The results show that ICT is used by 94.7% of respondents in the survey. Regular use of ICT was independent of gender and academic rank but varied by institutions. Constraints faced by the music educators include lack of adequate organizational facilitation and lack of skill necessary to use ICT effectively. Other hindrances to ICT use are financial and epileptic electric power supply as well as volume of academics’ workload. Even though use of computers appears high, the potentials of ICTs for facilitating and enhancing music education in Nigeria are still not being fully explored. Conclusions: There is need for formulating educational policies and designing appropriate training and mentoring programs, as well as providing infrastructural support, to help musical arts educators explore the potentials of ICTs to facilitate their job functions. 1 results 1
