- Orthopaedic injuries contribute to most musculo-skeletal health challenges in developing societies partly due to increasing rate of technological advancement and its associated consequences. Despite the little recognition experienced, traditional orthopaedic service due to the 'severity of most orthopaedic injuries which sometimes 'left patients incapacitated, decision making regarding treatment is sometimes determined by significant others and has implication for patients well being. This forms the focuss of this paper which is hinged on the health belief model as framework for explanation. Both qualitative and quantitative methods were used to elicit data. Questionnaire was administered to 357 randomly selected orthopaedic patients, while In-depth Interview (IDI) was conducted with 7patients and 14 practitioners. Findings revealed that majority of the patients (73.1%) belonged to the active age group (21-60 years); were males (74.5%) who engaged in occupations that predisposed them to orthopaedic injuries. Referral was mainly effected by family members (43:2%), former TOSP's patients (35.4%), friends (13.0%), and members of practitioners' ethnic groups (8.0%) who made these decisions because they were privy to effective treatment offered by the TOSPs. Intensive capacity building and collaboration with western practitioners was recommended for improved delivery of orthopaedic care. 2 results 2

- "Face recognition is an attractive field in enhancing both the security and the image retrieval activities in the multimedia world. Its natural basis in verification or identification purposes is a major factor of its wide acceptance in this evolving world of information technology. In this paper, experiments based on black African faces using Principal Component Analysis (OPCA) and Fisher Discriminant Analysis (OFDA) techniques were carried out. The design of the face recognition system was separated into three major sections - image acquisition and standardisation, dimensionality reduction, training and testing for recognition. Under static mode, experiments were performed on single scaled images without rotation, OPCA and OFDA both give recognition accuracies of between 89% and 97%;and) 88% and 98% respectively. These have been achieved at different levels of cropping. Despite the constraint created by the resources available, different results got showed that standard face recognition system could be developed using both algorithms. " 1 results 1
- "Sawdust particles soon after emission from the cutting machine usually move dynamically with transformation in some dimensions. This paper models the sawdust particle motion as a two dimensional transformation system of continuous time series. Cost could be saved using this approach instead of utilizing dynamic systems that depend on time history Two dimensional graphical representation of continuous time series of Duffing's dynamic system for sawdust particles was investigated with emphasis placed on application to sawdust particle motion and the saw machines. Pr~liminary studies were made using the harmonic functions, F(t) = Cos(wt) and F(t) = Sin(wt), for their familiarity in both science and technology communities. The solution to Duffing's model equation for the sawdust particles was sought from displacement and velocity perspectives, using the Runge-Kutta Algorithm. Linear transformation that guarantees non-negative values of time series was implemented. This was followed by the respective computation of the x- and y-components of the resulting time series values of the sawdust movement using a 21tmodulated time measured in radians. The graphical representations of the x- and y-components compared well quantitatively and qualitatively with the corresponding phase plots. The feasibility of modelling sawdust dynamics as emission from band saws was therefore demonstrated here, in approaches that thus advance knowledge of sawdust emission studies. " 1 results 1
- 'Theatre Arts' is essentially a visual arts discipline in which the elements of architecture, scenography and technology play very significant roles. However, these areas and aspects have suffered neglect, in the past, in the arena of Nigerian scholarship. Consequently, the present study aims at a historico-critical evaluation, analysis and documentation of the development and functions in the contemporary Nigerian theatre, as witnessed especially in and at Ibadan in the past twelve decades in broad terms and since 1948 (the founding year of the University of Ibadan) in particular. If there was in the pastan authentic African (especially Nigerian) theatre, then there ought to have been a corresponding typical and unique African theatre performance space form. Therefore there is a need to rediscover that form. But if the traditional African-particularly Nigerian theatre had had no unique and typical performance stage or space form, other than the village square, market place and the Kings' palaces, then it has to be accepted that the modern (present-day) architectural theatre forms of Africa and in particular of Nigeria have been imposed or have evolved from the cross currents of contacts with Western civilization and foreign influences and, therefore, they are basically foreign and of non- African origin. Consequently, the present search for a new theatre form, architecturally, would yield better results if the merger of the traditional and western modern architecture employing modern technology in equipping them to achieve flexibility, adaptability and timelessness could be pursued. In order to achieve that, what one has to do now is to critically examine the functionality of the present spaces and modify or refurbish them to suit the demands of the contemporary Nigerian theatre. However, most ideal would be the conception, design and realisation of new structures along the lines of new and long attested aesthetic principles and the results of technological researches arising from age-old experiments, new aspirations, current trends and future speculations. Since the arts and the sciences have always been the bedrock of human spiritual, psychological and economic development, and since technology has always aided the attainment of socio-political growth, technology, borrowed or developed, invented or transferred, has a great role to play in the development of Nigerian theatre. Hence, the investigation of its impact in the Nigerian theatre is a necessary and perhaps an inevitable task. The objects of the study are contained in an Introduction covering the purpose, scope, limitation, Overview of Literature, Methodology and Definition of Terms: while the findings in the three respective areas are presented in nine Chapters. Chapters One to Three contain review of literature, overviews of studies and projects in the three areas of study. Chapters Four and Five present, in chronological order, the historical development of theatre in Europe, America, Asia and Africa, especially Nigeria. Chapter Six looks at the genesis of theatre education, scholarship and practice, especially in the western world and recommends a model of training and desirable lines for the future development of theatre in Nigeria. Chapter Seven considers concepts and aesthetics of theatre arts forms and styles and relates these to the contemporary Nigerian theatrical endeavours, especially in the scenographic spheres. Chapter Eight treats the analysis, scenographic and technological executions of the production of the selected illustrative plays. Chapter Nine pursues the search for new physical theatre forms in their various parameters for Nigeria and examines the present state of the physical theatre structures and venues in and at Ibadan. The thesis sees architecture, scenography and technology as prime levers of the development of theatre arts in Nigeria. 1 results 1
- A charcoal fired reactor for small-scale production of biochar was successfully designed, fabricated and tested. The method of biochar production offered by this equipment was evaluated by comparing its output with a single barrel method of production. The results obtained during the test indicated that the efficiency of the equipment based on its output per kg of Cocoa pod husk was 79.9%. It has the capacity to produce 18.3 kg of Biochar from Cocoa Husk per day using 1 bag of local Charcoal. Cocoa pod Husk can be effectively used as raw material for Biochar production. The Specific Heat Capacity of Cocoa pod Husk was obtained as 3.8 kJ/kg K using the Choi and Okos model. The equipment can be afforded by small scale farmers at production cost of N24, 600.00.This machine can be easily used and maintained without any formal training. The reactor is therefore appropriate for use by subsistent farmers, and households for producing biochar on a small scale 1 results 1
- A university’s objective is to educate its students using information and communication technologies (ICTs) and teaching techniques that would enable its graduates become flexible and life-long learners that can easily adapt to the changes eminent in the information society. Achieving this aim requires among other factors, the adoption of appropriate teaching model such as the project based learning (PBL) which supports the inculcation of collaborative and lifelong learning skills, technology use skills, knowledge sharing skills and social networking skills into students. Consequently, this study was carried out to evaluate the use of mobile phones by students involved in PBL in three randomly selected private universities in Nigeria. The questionnaire was used as the instrument for data collection from 750 undergraduates students distributed across the three selected private universities in southwestern Nigerian states. This is to say that 250 students were sampled from each of the participating private universities whose population was estimated to be about 2000 students each. Also, the use of stratified sampling technique ensured that only those students that were in their second, third, fourth and fifth year in the sampled universities, who were presumed to have acquired required learning experiences, participated in the study. The result showed that a significant percentage of the students studied had mobile phones and that they used their mobile phones for communication, interactions, getting information, browsing the Internet, and sharing knowledge anytime they were involved in PBL. It was also revealed that mobiles phones can be used to strengthen PBL in higher institutions and can be used to implement information services provided for students in their university. Although private universities in southwestern Nigeria amounts to about 43.9% of private universities in Nigeria, a percentage that makes them a sizable representation of private universities in Nigeria, the fact that the study sampled population was drawn from only three southwestern Nigerian based private universities made generalizing the results of this study as the situation in Nigeria in appropriate. The study however, provides first hand information on the prospects, gains and challenges mobile phones offer as appropriate education technology for implementing PBL in Nigerian universities 1 results 1
