Empowering Farmers Through Discovery Learning: A Case Study Of Farmer Field School (Ffs) Training On Cocoa Integrated Pest Management (Ipm) In Ondo State, Nigeria
The study assessed the effectiveness of Farmer Field School (FFS) training on farmers\' competence in Integrated Pest Management of cocoa and the transfer of knowledge to others in Ondo State, Nigeria. Using structured questionnaire and interview schedule, data from 60 randomly selected respondents made up of 30 trained FFS graduates (primary trainees) and 30 others trained by FFS graduates (secondary trainees) were used for the study. Findings show that a higher proportion of the respondents in both categories of trainees are males and a majority are married and belong to 31 –50 years age bracket. The result shows that about 63% of the primary trainees transferred the knowledge to others while the secondary trainees did not transfer the knowledge. Respondents from both categories of trainees found the FFS training to be more efficient than other trainings. FFS was found to improve the competence level of both
categories of trainees especially on ability to conduct field studies and making observation
themselves and also improve farmers\' confidence and reduction in agrochemicals use. However, the effectiveness of FFS was more pronounced in primary trainees than the secondary trainees. Respondents\' level of education (b = 2.765), number of years of cocoa farming (b=1.785) and participation in Farmer Field School training (b = 2.364) had significance influence on the respondents\' competence in cocoa IPM. For better efficiency, the inclusion of Farmer Field School training in agricultural extension programmes in addition to T&V system is recommended.

Cancer Prevention, the Need to Preserve the Integrity of the Genome at All Cost
Introduction: The entire genetic information carried by an organism makes up its genome. Genes have a diverse number of functions. They code different proteins for normal proliferation of cells. However, changes in the base sequence of genes affect their protein by-products which act as messengers for normal cellular functions such as proliferation and repairs. Salient processes for maintaining the integrity of the genome are hinged on intricate mechanisms put in place for the evolution to tackle genomic stresses. Aim: To discuss how cells sense and repair damage to their deoxyribonucleic acid (DNA) as well as to highlight how defects in the genes involved in DNA repair contribute to cancer development.Methodology: Online searches on the following databases such as Google Scholar, PubMed, Biomed Central, and SciELO were done. Attempt was made to review articles with keywords such as cancer, cell cycle, tumor suppressor genes, and DNA repair. Results: The cell cycle, tumor suppression genes, DNA repair mechanism, as well as their contribution to cancer development, were discussed and reviewed.Conclusion: Knowledge on how cells detect and repair DNA damage through an array of mechanisms should allay our anxiety as regards cancer development. More studies on DNA damage detection and repair processes are important toward a holistic approach to cancer treatment.Keywords: Cancer, deoxyribonucleic acid, genes, genom
