Relevance and Use of News Bulletin in Public Information Dissemination within Academic Communities: A Case Study of Three Universities in Ogun State, Nigeria

This study focuses on the relevance and use of news bulletin in public information dissemination within academic communities. Three Universities in Ogun State, Nigeria were selected for the study. A total of 500 copies of questionnaires were distributed but only 432 copies were returned for analysis. The study utilized factor analysis to extract major factors that promote the use of the medium in public information dissemination within the community. The findings revealed that almost all respondents see news bulletin as a good means of communication and collaboration and the major factors that promote its uses in the community are utility, worthiness, credibility and consistency. However, a good number of them believed that it does not give room for feedback. In conclusion, the study recommends that management should correct the paucities in the production and distribution systems of the medium in reporting current happenings in the community at regular intervals.

KEEPING UP WITH GLOBAL TRENDS: ASSESSING PRIVATE TERTIARY INSTITUTIONS' TRAINING AND RETRAINING PROCESSES IN NIGERIA

This study examines the lifelong learning processes of tertiary institutions in Nigeria. One of the most unique attributes of Information and Communications Technology (ICT) is the ability to simplify processes and aid efficiency. Institutions are not run the way they used to some decades back. This is attributed to the evolution of ICT. Since new technologies evolve at astonishing speed, it should be expected that tertiary institutions should not only learn of them, but also adopt them in their administrative processes. This brings to the fore the role of staff members in ensuring the success of this process. This study, therefore, examines the processes adopted by selected tertiary institutions to train and retrain their staff to be able to keep up with ICT trends using multinomial logistic model approach

E-INVIGILATION: PANACEA TO EXAMINATION MALPRACTICE IN NIGERIA

e- Invigilation is the use of remote-controlled terminals that are linked with the main servers of any institutions. E-invigilation is very important in managing both offline and online invigilation of examinations. This is vital for eradicating examination malpractice on the part of the students. There is a disenchantingly slow evolution of ICT use in the invigilation of students in the Nigerian educational school system. The main roles of ICT in education are to provide the prospects and trends of integrating communication technology into the educational processes. Hence, one of the vital areas of incorporating ICT is in the invigilation of examination in order to bring to fore its effectiveness. In reality, an efficient and effective system of the invigilation process is essential in increasing the credibility of the entire educational assessment in Nigeria. This fundamental area constitutes an inevitable reality in modern education, especially with security of examinations in mind that attracts the law of morality. The method of data analysis incorporates both descriptive and logistic regression modeling. Therefore, Invigilation should not be played down with regard to the issues of assessment. The study proposes a model that is relevant for e-invigilation, discusses the pros and cons of einvigilation in system of education in Nigeria and makes policy recommendations towards incorporating e-invigilation in the educational system of higher education in Nigeria

AN ASSESSMENT OF HOUSEHOLD SOLID WASTE RECOVERY AND UTILIZATION IN IBADAN: CASE STUDY OF IBADAN NORTH LOCAL GOVERNMENT AREA

This work aims to assess household solid wastes based on recovery and utilization within three different income groups of Ibadan North local government area and investigate the management system. Ibadan north local government was divided into three groups based on income generation. Household Solid Wastes generated on daily basis were sampled from each section. The average Household Solid Wastes (HSW) generation for the high income group, was 0.62kg/head/day, 0.34kg/head/day for medium income group and 0.24kg/head/day for low income group respectively. While the recoverable wastes were found to consist of 21.5, 38.8, 25.8, and 13.9% respectively for paper, plastic/rubber, nylon and metal/tin wastes. The utilization percentage were, 20% paper wastes, 5.8% plastic/rubber wastes, 1.7% nylon wastes and 6.7% metal/tin wastes among all three income groups. Extent of utilization to that of recoverable wastes was substantially low when compared with the total composition of waste in all the groups that cannot be reused and recovered. Hence, this indicates that a larger quantity of recoverable waste goes directly from household to landfill unrecovered.  As a result, efforts should be made to recover all the recyclable wastes which would be made easier through   sorting of wastes before disposal, as this will go a long way in reducing the quantity of wastes that goes into landfill

Condition-Based Monitoring of Kiln Induced Draft Fan in A Dry Process Cement Plant for Efficient Utilization

Associated downtime and economic loss caused by replacement/maintenance of equipment necessitated pro-active technique known as Condition-Based Monitoring to prevent/reduce failures. This study evaluated the vibration of Kiln Induced Draft (KID) of cement plant before and after failure. Vibration data was acquired using accelerometer probe and data obtained were analyzed statistically by employing t-Test at 95% confidence. Results showed that vibration signals measured in mm/s for KID motor and fan bearings (non-drive and drive ends) in the horizontal plane recorded higher values than vertical and axial planes when measured before failure occurrences. After failures, horizontal plane values increased by more than 120% while those measured in the vertical and axial planes increased by less than 100%, making horizontal plane vibration measurement a more suitable parameter for predicting the machinery health condition. The t-Test conducted showed that mean differences in values of vibration signal data before and after failure are not zero but negatives (signal before failure < signal after failure). Outputs from tests of significance using two-tailed t-Test indicated that the differences in values of vibration data signals are not significant at (p≤ 0.05) when considering “equal variance not assumed”. The non-significance of these mean differences may indicate that the present operational vibration signal level should be maintained at values in order that significant difference may be observed between periods before failure and after failure for efficient prediction of failure, as the present 1.5-3.5 mm/s range is likely not a good range for efficient failure prediction

E-Govemance and E- Participation: Panaceas for Effective Mobilization of Manpower and Resources in Selected Local Governments in Ogun State.

E-governance and e-participation are important stages in the advancement of government processes. They both offer great opportunities as well as new challenges despite the opportunities they offer; they also introduce new challenges especially in Nigeria with emphasis on selected local governments in Ogun State. Egovernance is a new phenomenon in African countries and Nigeria is fast aligning into it, with the aim of addressing many challenges attached to development in Nigeria. AdoOdo/ Ota, Sagamu, Yewa South, Abeokuta South and Ijebu Ode local governments function primarily along the traditional colonial administrative system. Features of this system are bureaucracy, nepotism top-bottom chain command structure, et cetera. Hence, problems of this age long governance are legion which e-governance presumably appears to solve. Under a full-fledged e-governance, system optimization of resources is paramount. Despite all known benefits of e-governance, many challenges are embedded in the system. Changes are often hindered, due to lack of confidence in the process and there is the perceived displacement of personnel through application of information communication technology (ICT). This study considers sectoral aggregation of local government systems such as personnel, community development or relations, Infrastructural needs, spatial environment, etc. Structured and unstructured interviews will be conducted and questionnaires were administered in order to gather data in areas of education, health, recreation, electricity, water supply, empowerment, waste management, traffic control and security. This study specifically evaluated the personnel's understanding of ICT application in governance and community or public participation and exercise of civic responsibility. The research design utilized both descriptive and survey approach in its method of data collection. In order to realize the objectives of the current study, the method of data analysis involved both descriptive analysis with the use of frequencies and percentage distributions in analyzing the basic information of the targeted audience. The formulated hypotheses were subjected to statistical validation using multivariate regression analysis. This methodological approach enabled us ascertain whether there exists any significance relationship between eGovernance and effective mobilization of manpower and resources considering the selected local government areas for this study.

Liver mitochondrial membrane permeability modulation in insulin-resistant, uninephrectomised male rats by Clerodendrum volubile P. Beauv and Manihot esculenta Crantz

Background: Non-alcoholic fatty liver disease, which occurs in people who are not alcohol drinkers, describes some of the pathogenic conditions that may be in the least characterized by simple steatosis or can be as serious as non-alcoholic steatohepatitis and cirrhosis. Its mechanistic pathogenesis has been said to arise from insulin resistance and oxidative stress, which may be compounded by obesity. An experimental model showing, systemic insulin resistance, obesity and accumulated hepatic fatty acids was created in adult male rats using high-fat diet manipulation and surgical removal of the left kidney (uninephrectomy). This study sought to identify the impact of these multiple burdens on the liver mitochondrial membrane permeability transition pore opening, and the possible in vitro effects of the extracts of Clerodendrum volubile and Manihot esculenta leaves on the membrane permeabilization. Results: The results indicated that the methanolic extract of Clerodendrum volubile leaf inhibited mitochondrial membrane pore opening in the insulin resistance condition or when it is followed by uni-nephrectomy, while the ethanolic extract of Manihot esculenta leaf does the same in the insulin resistance condition both prior to and following uni-nephrectomy. Conclusion: Since the vegetable extracts were able to abrogate mitochondrial pore opening at low concentrations, the structural integrity of the mitochondria can possibly be restored over time if treated by the vegetable extracts. Research efforts should, therefore, be made to harness the drugability of the bioactives of these vegetables for use in the treatment of non-alcoholic fatty liver disease arising from insulin resistance and renal failure.Fil: Ajayi, Ebenezer Idowu O.

Effects of crude ethanolic extract of Garcinia cambogia on the reproductive system of male wist ar rats (Rattus novergicus)

15 male rats were grouped and administered crude ethanolic extracts of Garcinia cambogia seeds to test the effects on the histology of the testis and sperm counts. Group A served as the control while Groups B and C received 100 and 200 mg/kg body weight of extracts, respectively. The administration was done orally once a day, six days a week for six weeks. The routine histological preparation at the end of administration revealed increase in the interstitial spaces, degeneration of the Ledgid cells and distortion in the arrangement of the cells of spermatogenic series. The sperm counts revealed a significant increase in the experimental groups when compared statistically with the control (p<0.05). It was 81.5 ± 13.62 ´ 10^6/ml and 70 ± 12.98 ´ 10^6 /ml in groups Band C, respectively, as compared to 59.8 ± 2.14 ´ 10^6/ml in the Control group
