Knowledge and perception of e-health and telemedicine among health professionals in Lautech teaching hospital, Osogbo, Nigeria
O Abodunrin, T Akande
International Journal of Health Research , 2009,
Abstract: Purpose: To assess the knowledge and perception of health professionals in LAUTECH Teaching Hospital (LTH), Osogbo on e-health and telemedicine Methods: In a cross-sectional descriptive survey, 110 different health professionals were selected by proportional multi-stage sampling in LTH, Osogbo using self-administered, semi-structured questionnaire to assess their knowledge and perception of e-health and telemedicine. Results: Only 34.1% had good knowledge of what ehealth and telemedicine entails and only 13% of the respondents have attended any relevant workshop. Respondents’ profession and attendance in workshop affected their knowledge. Although as much as 91.6% were in support of introduction of e-health practice in Nigeria, most of them believed that financial implication, illiteracy and poor infrastructure, such as electric power supply and internet services, could limit its full application. Conclusion: Although the knowledge of the health professionals on e-health and telemedicine was poor, majority of them were in support of the services. There is therefore the need to intensify training workshops for health professionals and improve electricity and Electronic communications.

Ife O. Abodunrin,Simeon A. Dosunmu
Pakistan Journal of Social Sciences , 2012, DOI: 10.3923/pjssci.2012.27.32
Abstract: This study has assessed over parenting practices in Lagos and how this has affected children learning efficiency. Using 75 parents and 375 secondary school students as participants, survey method was used to obtain required information by the process of interviewing and questionnaires. A mixed method of research was adopted involving quantitative and qualitative approaches to arrive at conclusions. The research hypothesis had stated that over parented children are the male in gender, academically sounder than the non overprotected ones but socially naive. This had three corollaries stated in the null form. These were tested along with four research questions. The results provided that there is no significant relationship in the degree of over parenting between male and female children; there is no significant difference in the academic performance between over parented children and their counterparts who are not but significant difference existed in the degree of social naivety between children of over parenting parents and their counterparts who are with no traces of over parenting. Improvements in the school system with emphasis in the provision of boarding facilities for all children were suggested and further study of the character and their effect on children learning efficacy.
Awareness and perception toward referral in health care: A study of adult residents in Ilorin, Nigeria
Abodunrin O,Akande T,Osagbemi G
Annals of African Medicine , 2010,
Abstract: Background and Objective: The Nigeria Health System operates three levels of health care, which correspond to the tiers of government and interacts through a referral system. The national health policy recommends the Primary Health Care (PHC) as the entry point to health care system. However, these facilities are poorly managed leading to underutilization. Therefore, people usually attend any facility that will meet their needs, not considering the appropriateness of the level of care. This study is to determine the awareness and perception of adult residents in Ilorin toward referral in health care. Methods: A cross-sectional descriptive survey was conducted among 366 adult residents in Ilorin, selected by multi-stage sampling technique. Data were obtained using a semi-structured questionnaire, appropriately scored and analyzed with Epi-Info 2005 computer software. Results: Only 22 (6.0%) respondents knew that PHC is supposed to be the fi rst point of call when ill and 25 (6.8%) were aware that referral hospitals have the right to reject patients without referral. More than two third, 256 (69.9%) of the respondents felt it will be unreasonable for any hospital to reject patients on the basis of not being referred. The level of education was signifi cantly associated with the knowledge and perception of referral in the health care. Conclusion: There is low awareness and poor perception of referral protocol in the health care system among the people of Ilorin. The higher the level of education, the more knowledge the respondents have about referral in the health system and the more likely they have correct perception of referral in health care. The Nigeria health care system policy on referral and appropriate hospital utilization could be more effective if public awareness is created about it via the media while making effort to improve the credibility of the PHC.

M.A. Belewu,O.A. Abodunrin
Pakistan Journal of Nutrition , 2008,
Abstract: The effect of preparing kunnu from Tiger nut (A) Millet (B) and sorghum (C) on the proximate composition, mineral content and sensory qualities were evaluated in a completely randomized design model. The results revealed highest fat percentage for Tiger nut based kunnu (Treatment A) and poorest for millet based kunnu (Treatment C). The crude protein content of Tiger nut based kunnu (A) was greatest (p<0.05) compared to other Treatments B and C which are similar. There was similarity in the energy content of all the Treatments. The sensory qualities (flavour, colour, taste, texture, general acceptability) were however, observed to increase significantly (p<0.05) in the Tiger nut based Kunnu (A) compared to other sources (B and C). Furthermore, utilization of Tiger nut in the preparation of kunnu was favoured by market price compared to sorghum and millet. Tiger nut based kunnu cost $0.29 per Kg while millet and sorghum based kunnu cost $0.36 per kg each, making a difference of $0.07 per kg surplus. In conclusion, the results obtained show that preparation of kunnu from Tiger nut was cheaper while more nutritious beverage with a high level of acceptability was obtained.

International Agrophysics , 2005,
Abstract: Equilibrium relative humidity – moisture content data for palm kernel at five different temperatures (40, 50, 60, 70, and 80 °C) and moisture content values ranging from 8.6 to 19.1% (dry basis) were determined using the vapour pressure manometric method. A non-linear least squares regression programme was used to evaluate four moisture sorption models. The models were compared using the standard error of estimate, the mean relative percent deviation, the fraction-explained variation, and residual plots. Modified Henderson model was found to be the best model for predicting both the equilibrium moisture content and equilibrium relative humidity of palm kernel. The experimental data and the model that best predicted the equilibrium relative humidity were used to determine the thermodynamic characteristics of palm kernel. The heat of vapourization of moisture in the kernel decreased with increase in moisture content and approached the latent heat of pure water at a moisture content between 28 and 32% dry basis. The spreading pressure increased with increase in relative humidity and was not significantly affected by temperature. Net integral enthalpy decreased with increase in moisture content and became asymptotic in trend as the moisture content of 24% (db) was attained. Net integral entropy had positive values in the moisture range from 8.6 to 15% (db) and negative values from the moisture content of 15.3% (db) till 20% (db) was approached.

Temitope Abodunrin, Adenike Boyo, Olugbenga Obafemi, Timothy Adebayo
Materials Sciences and Applications (MSA) , 2015, DOI: 10.4236/msa.2015.67066
Abstract: Fresh leaves of oil bean (P. macrophylla) were used as sensitizers for fabrication of dye sensitized solar cells (DSSCs) at four dye pH values of 2.58°C at 23.7°C, 2.62°C at 22.2°C, 2.65°C at 22.3°C and 3.61°C at 22.1 °C. The methanol extracts of P. macrophylla were extracted and used as sensitizers for the development of dye sensitized solar cells. The solar cells sensitized by P. macrophylla leaf extracts realised up to short circuit current (Jsc) 0.16 mA/cm2, open circuit voltage (Voc) 0.045 V, Pmax 0.031 mW/ cm2 and fill factor (FF) 0.50. The energy conversion efficiency (η) of the DSSCs is 0.43%. Phytochemical screening of P. macrophylla leaf extract shows the presence of flavonoids and anthraquinones. The nanostructured dye shows conversion of solar energy into electricity using low cost natural dyes as wide band-gap semiconductor sensitizers in DSSCs. This will provide economically viable substitute to silicon p-n junction photovoltaic (PV).

Abstract: Background: Long-term complications of prolonged obstructed labour are multisystemic, obstetric fistula about the most devastating. Efforts at controlling obstetric fistula pay little attention to the non-fistulous injuries which reduce the quality of life of the affected women even after a successful fistula repair. The objectives of this study were to determine the burden of the non-fistulous complications among fistula patients, identify these injuries and the factors associated with them. Methods: This cross-sectional study was conducted at the National Obstetric Fistula Centre, Abakaliki, South-East Nigeria from July to December 2016. The hospital has performed over 2600 free fistula repairs. This study was approved by the Research and Ethics Committee of the hospital. The study population comprised of women who developed obstetric fistula following prolonged obstructed labour. Direct questioning, examination findings, operation findings and laboratory results, using a pre-tested, semi-structured and interviewer-administered proforma were used to collect data. Informed consent was obtained from the subjects. Data were analyzed using the Statistical Package for Social Sciences [SPSS] version 21. Frequency and proportions were used to describe categorical variables while means and standard deviation were used to describe continuous variables. Association between categorical variables and direct obstructed labour injuries was tested using chi-square test and predictors of obstructed labour injuries were determined using logistic regression.

International Journal of Health Research , 2009,
Abstract: Purpose: Several studies have documented the high sexual activities and risky sexual behaviours among adolescents in most parts of the world thus putting them at high risk of contacting the HIV infection and other complications. This study aimed to determine sexual risk factors among adolescents in secondary schools in urban areas of Osogbo in South western Nigeria. Methods: A descriptive cross sectional study was done among 521 public secondary school students in Osogbo, Southwestern Nigeria, using multistage sampling technique and semi-structured administered questionnaire. Data were analyzed using the SPSS software package version 15. Results: Appreciable number (31.5%) of the respondents have had sexual intercourse (the mean age of sexual debut being 15.2+1 yr). Some of them (14.6%) had had more than one sexual partners, 17 (3.3%) had visited commercial sex workers before, 33 (6.3%) had been raped previously while 25 (4.8%) had been treated for STIs symptoms in the past. Most respondents were aware of common modes of transmission of the HIV virus. Less than half (32.8%) of the respondents were prepared to be screened for HIV infection. Conclusion: Many adolescents studied were sexually active, and taking a lot of risky sexual behaviours that could facilitate transmission of HIV. Advocacy programme that will make adequate information about sexual health available to the adolescents needs to be intensified.
