Published: March 2022

Introduction: It is well documented that some forced exercises can have bad effects on the genital system. Melatonin is a potent antioxidant that is effective in reducing the physical stress.&nbsp;
Aim: The aim of this study was to evaluate the supportive effect of melatonin on the quality of spermatogenesis, including count, motility, morphology, viability, and apoptosis of sperm following a forced treadmill exercise.
Materials and methods: A total of 40 adult male Sprague-Dawley rats were used in this experimental study. All rats were divided into five groups: control group, sham M group, melatonin (M) group, forced treadmill exercise group (Ft), and melatonin with forced treadmill exercise (MFt) group. The experimental group was trained to force treadmill stress for one hour of forced treadmill exercise daily, five days weekly for eight weeks. Then the sperm quality parameters were measured after dissection and removal of epididymis. Spermatogenesis and germ cell apoptosis were evaluated using Miller and Johnsen&rsquo;s score and TUNEL staining separately.
Results: Results showed the count, motility, morphology, and viability of sperm in forced treadmill-melatonin administrated group, significantly enhanced by melatonin treatment compared to the treadmill exercise group (p&le;0.01). Also the number of apoptotic germ cells significantly decreased in treadmill exercised-melatonin administrated group compared to the treadmill exercised group.
Conclusions: These results suggest that administration of melatonin can protect the testis against the detrimental effect of forced treadmill exercise in adult male rats.

Introduction: Pulp sensitivity tests are commonly used for assessment of pulp vitality. However, indirect assessment of pulp vitality by evaluation of nerve response and subjective nature are the main limitations of these tests. Pulse oximetry is used for assessment of blood oxygen saturation in medicine, and its efficacy for assessment of pulp vitality needs to be evaluated.
Aim: This study aimed to assess and compare the efficacy of pulse oximeter with a modified probe, cold test, and electric pulp test for evaluation of pulp vitality in permanent immature teeth.
Materials and methods: This cross-sectional study was conducted on 240 permanent maxillary incisors in four groups based on the type of tooth (central and lateral incisors) and degree of root development (complete or incomplete). Also 40 endodontically treated central and lateral incisors teeth in two groups were evaluated as negative controls. Pulp vitality was assessed by an expert clinician using pulse oximeter, cold test, and electric pulp test. Based on the true and false positive and negative responses, the sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood, diagnostic accuracy, and diagnostic odds ratio were calculated.
Results: The pulse oximeter showed diagnostic accuracy of 98.7% in the permanent central incisors with complete and incomplete roots and 100% in the permanent lateral incisors with complete and incomplete roots. The diagnostic accuracy of the electric pulp test was 76.2% and 92.5% in the incomplete and complete central incisors, respectively, and 76.2% and 83.7% in the incomplete and complete lateral incisors, respectively. The cold test had a diagnostic accuracy of 85% and 92.5% in the incomplete and complete central incisors, respectively, and 91.2% and 88.7% in the incomplete and complete lateral incisors, respectively.
Conclusions: The findings of this study showed that pulse oximetry has a higher specificity and better accuracy than the cold test and the electric pulp test in assessing the pulp vitality in the diagnosis of vital teeth and should be introduced as a suitable method for this purpose and preferred to the cold and electric pulp tests for more evaluation to diagnose pulp vitality.

Competence Based Curriculum (CBC) was introduced is schools to cater for the demand of employers to have skilled and competent employees who could competent in the world market. The implementation of CBC in schools is facing many challenges; some of them originate from teachers colleges where the preparation of teachers is done to take the roles. The purpose of this study was to examine the challenges teachers colleges face in teaching with CBA. The study employed quantitative and qualitative approaches. Specifically, the study aimed to answer the following questions: what are the challenges of teaching and learning with CBC in teachers colleges? and, what challenges do tutors face in integrating competence based approaches (CBA) in teachers colleges? The findings showed a significant efforts from governmental, institutional, and individual initiatives towards competence based curriculum implementation. However, there are various challenges facing teachers colleges and tutors in teaching and integrating CBC knowledge and skills in the training. The identified challenges include: poor government support, shortage of teaching and learning materials, poor infrastructures, shortage of training opportunities for professional development and lack of follow up activities from curriculum planners. The author’s recommendation is given out for further action to the government, training institutions and education stakeholders to work together for implementing CBC to teachers. As well researchers should work on the suggested area. The study concludes that teachers are not well prepared in colleges for effective CBC implementation in schools due to the aforesaid challenges.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0923/a.php" alt="Hit counter" /></p>

Authors: Yédia Dadjo Servais Dieu-Donné 
Published: March 2022

This study seeks to apply speech act theory to the analysis of Frank Ogodo Ogbeche’s ‘Harvest of Corruption’ on the basis of a mixed method. It aims at identifying, analyzing and interpreting the different speech acts in the selected play for the purpose of decoding meanings. The results show that through representative acts the author has depicted thoroughly heinous practices that affect negatively the development of African countries. Through directive, he is inviting political authorities to look at the pitiful state of their countries. Through commissive, he is indicating how governments should commit themselves to take measures to clean up public services. Expressive acts have enabled him to express sorrow and feeling of desperation in regards to the pitiful state of African countries. Through declarative, he indicates how immediate changes can be operated by sentencing all guilty authorities to many years of imprisonment. These results have enabled the researcher to contend that the author has directly and indirectly depicted African countries in general and more specifically Nigeria as characterized by embezzlement, drug dealing, bribery and corruption, abuse of the public offices, betrayal of people’s trust.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0917/a.php" alt="Hit counter" /></p>

Authors: Njuguna Benson Chege , Kipkoech Lydia , Wanami Simon 
Published: March 2022

This study sought to find out the effect of management of ICT infrastructural resources on the implementation of TPAD Policy in Public Secondary Schools in Trans Nzoia County, Kenya. The study was guided by ‘goal-setting theory. Concurrent triangulation design was used to sample 342 Principals and teachers from a target population of 2340 respondents comprising of 242 principals and 2098 teachers from 242 public secondary schools. Stratified and random sampling methods were used to select respondents. Questionnaires were used to collect information and opinions from Principals and teachers. Expert judgments from supervisors were used to improve content validity. Data was analyzed using descriptive and inferential statistics. The results of the study were presented using frequency tables and percentages. From the linear regression model, the study revealed a positive significant effect of teachers’ perception on implthe ementation of TPAD policy. From linear regression model, (R2 = .206) showed that ICT infrastructure resources account for 20.6% variation in the implementation of TPAD policy. There was a positive significant effect of ICT infrastructure resource (β3=0.700 and p value&lt;0.05) on implementation of TPAD policy. Therefore, an increase in ICT infrastructure resources leads to an increase in the implementation of the TPAD policy. The null hypothesis (Ho1) was rejected. ICT infrastructure resoresources a significant influence on the implementation of TPAD policy. This implies that for each increase in the ICT infrastructure resource, there was more implementation of the TPAD policy. The study concluded that the management of teaching staff affects the implementation of TPAD in public secondary schools in Trans Nzoia County. Head teachers with better staff management skills helped teachers to shift to the new paradigm of an appraisal system which has openness, reliability, and accountability as its hallmarks. The Ministry of Education and TSC should improve ICT infrastructure especially in sub-county schools and continuously capacity build teachers and school administrators on emerging trends in education management information systems. There is a need for the ministry of education to provide ICT infrastructural resources in every public secondary school in Trans Nzoia County in order to enhance the implementation of TPAD policy.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0994/a.php" alt="Hit counter" /></p>

Published: March 2022

This study investigated Realistic and Investigative personality types as predictors of achievement career aspiration of secondary school students in Anambra State, Nigeria. Two research questions guided the study while two null hypotheses were tested at a 0.05 level of significance. The study adopted a correlation research design. The study was carried out in Anambra State. The sample of 2,700 SS1 and SS 2 students were selected from a population of 32,450 senior secondary school students. Two research instruments were used for data collection. These are the Achievement Career Aspiration Scale (ACAS) and Personality Types Questionnaire (PTQ). The internal consistency reliability of the instruments was established using Cronbach Alpha statistics. The results are as follows: ACAS 0.891; PTQ 0.942. The reliability Coefficients for PTQ clusters are Realistic 0.891, Investigative 0.928. Copies of the questionnaire were distributed and retrieved through a direct delivery method. Data collected were analysed using Statistical Package for Social Science (SPSS). Simple linear regression analyses were used in answering research questions and testing the hypotheses. The finding of the study revealed among others that the Investigative personality type showed a significant prediction of achievement career aspiration of the students while the Realistic personality type does not significantly predict their achievement career aspiration. Based on the findings of the study, it was recommended that Guidance Counsellors working in secondary schools should organise assessment tests to assess students’ personality types in their school when the students join the school in class one, so as to guide them in their possible career paths.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0905/a.php" alt="Hit counter" /></p>
