S. Sumathi css1@tnau.ac.in <p>Information and Communication Technologies have become more prevalent in the last few years and has made a great impact on society. Worldwide, a lot of education programs offer new forms of education that are frequently supported by information and communication technology (ICT) to cater to young minds. E-learning in particular has been adopted by educational institutions all over the world and it is being used as a part of “blended learning” where it is incorporated into systems along with traditional classroom learning. Nowadays, it has become more relevant than ever due to the COVID-19 pandemic that the world is facing. Although these systems differ from classroom learning, they allow easy communication among teachers and students at any time necessary and provide an entire repository for students to use. For teachers, it acts as an environment for creating courses, assignments, giving feedback and grading students. In this paper, two such E-learning platforms namely Moodle and Google Classroom are compared and contrasted based on their usability and simplicity.</p> 2020-09-25T00:00:00+00:00 ##submission.copyrightStatement## https://journalair.com/index.php/AIR/article/view/30246 Inventory Management Practices and Operational Performance of Manufacturing Firms in Ghana 2020-09-25T14:36:42+00:00 Richard Kofi Opoku ropoku43@gmail.com Helen Mawuena Fiati Gregory Kaku Joseph Ankomah Faustina Opoku- Agyemang <p><strong>Aims: </strong>The study examined the effect of different inventory management practices on the operational performance of manufacturing firms in Ghana.</p> <p><strong>Study Design:</strong> The study adopted the descriptive survey design.</p> <p><strong>Place and Duration of Study:</strong> The study was conducted among manufacturing firms within the Accra, Tema and Kumasi metropolises in Ghana between November 2019 and February 2020.</p> <p><strong>Methodology:</strong> The study randomly sampled 152 Procurement and Operations managers and officers from 246 registered manufacturing firms with the Association of Ghana Industries. The manufacturing firms are specifically located within the Accra, Tema and Kumasi metropolises. The study gathered primary data using structured questionnaires of which analysis was done using both descriptive and inferential statistical tools including mean, standard deviation and ordinary least square regression.</p> <p><strong>Results:</strong> Using 114 valid responses, the study found manufacturing firms in Ghana to have high preference for Strategic Supplier Partnership (M=3.63) and Activity Based Costing (M=3.56, whereas they had least preference for Just In Time (M=3.06). The ordinary least square regression analysis showed that all the different inventory management practices: strategic supplier partnership (<em>P</em>=.000), activity based costing (<em>P</em>=.025), vendor managed inventory (<em>P</em>=.008), economic order quantity (<em>P</em>=.19), material resource planning (<em>P</em>=.000) and just in time (<em>P</em>=.009) are significantly and positively associated with operational performance.</p> <p><strong>Conclusion:</strong> The study concluded that inventory management practices especially strategic supplier partnership plays tremendous roles in improving the operational performance levels of manufacturing firms in a developing economy notably Ghana.</p> 2020-09-18T00:00:00+00:00 ##submission.copyrightStatement## https://journalair.com/index.php/AIR/article/view/30247 Antimicrobial Efficacy of Toothpastes Containing Fluoride against Clinically Isolated Streptococci mutans 2020-09-22T06:16:16+00:00 Eze E. Ajaegbu ajaegbuee@yahoo.com Calister U. Ezeh Adaobi J. Dieke Adaora L. Onuora Jane I. Ugochukwu <p>Dental caries is one of the prevalent oral diseases which affect all ages. Many chemical substances with antimicrobial properties, are effective against microorganisms causing dental caries. The objective of this study was to check the antimicrobial efficacy of some toothpastes&nbsp; found in Enugu metropolis, Nigeria more specifically against clinically isolated <em>Streptococci mutans</em>. The antimicrobial efficacy of different brands of toothpastes marketed in Enugu metropolis&nbsp; was assayed against <em>Streptococci mutans</em> using the agar well diffusion method. The clinical <em>Streptococci mutans</em> used for this study were taken from carious lesions of patients that&nbsp; attended the clinic at Federal College of Dental Therapy and Technology, Trans Ekulu, Enugu, Nigeria and were isolated and cultivated using traditional laboratory methods. The present&nbsp; study has shown that toothpaste which contains mint extract as herbal constituent and sodium fluoride had the highest antimicrobial activity, followed by toothpastes containing only sodium monofluorophosphate. Herbal toothpaste with mint can be a safe and effective alternative in the prevention of dental caries.</p> 2020-09-22T00:00:00+00:00 ##submission.copyrightStatement## https://journalair.com/index.php/AIR/article/view/30248 FTIR and UV-Visible Spectrophotometric Derivatization Studies of Artemether 2020-09-24T11:44:28+00:00 Jane I. Ugochukwu Eze E. Ajaegbu ajaegbuee@yahoo.com Chidinma R. Chukwunwejim Ikemefuna C. Uzochukwu <p>This study was aimed at confirmation of the purity and identity of the artemether and development of an ultraviolet spectrophotometric method for the assaying of artemether utilizing p-nitroaniline as a derivatizing agent. Melting point and Fourier transform infrared spectrophotometer (FTIR) methods were used to confirm the purity and identity of the artemether used in the study. The derivatization process was carried out between 100 µg/ml of the artemether and 500 µg/ml of p-nitroaniline in different molarities (0.5, 1, 2, 3, 4, 5M) of HCl at 60ºC for 45 mins. The melting point ranged between 86-89ºC and the FTIR determination revealed a band at 3169.978 cm-1 due to O-H stretching vibration and C-H stretching at 2996.039 cm-1. There was no observed difference in wavelength between the p-nitroaniline spectrum and the spectra of the derivatized products in different molarities of HCl. p-nitroaniline may not be a proper derivatization reagent for the assay of artemether in pure or dosage form.</p> 2020-09-24T00:00:00+00:00 ##submission.copyrightStatement##
