Exploring the Impact of Learning Technologies in Teaching Interaction Design: A Case Study at First Technical University, Nigeria

Teaching interaction design poses unique challenges as it requires discussing design principles for interactive products. Conventional methods like static slides and lectures often fail to effectively engage learners, leading to reduced satisfaction and limited active participation. To address this issue, an action research study was conducted at First Technical University, Nigeria, to investigate the impact of incorporating learning technologies in teaching interaction design. The study involved 21 purposively selected 200 level students from the Computer Science and Software Engineering departments who willingly participated to compare their previous instruction in interaction design.The study aimed to adapt the current learning approach by emphasizing technology-enhanced methods such as flipped classrooms and online teaching. By integrating technology-equipped pedagogy, the research aimed to enhance learners' engagement and interest in the subject.The findings reveal that the integration of learning technologies in teaching interaction design has a significant impact on student engagement and understanding. The gradual inclusion of various technologies transformed students from passive learners to active participants who freely expressed their ideas, engaged in critical discussions, and applied design principles in practical contexts. The results also highlight the importance of aligning pedagogy with learners' needs and cultural context. By creating a less formal learning environment that encourages open expression of ideas and active participation in discussions, the use of learning technologies not only enhances the application of design principles but also fosters the development of students' personalities and soft skills. Notably, communication skills, leadership abilities, teamwork, and project management skills exhibited significant improvement throughout the study cycles.

Adoption of Point of Sale Terminals in Nigeria: Assessment of Consumers' Level of Satisfaction

The adoption of Point of Sale Terminal for financial transaction is expected to reduce large volume of currency in circulation. However, the adoption of the e-payment system is comparatively lower to other payment systems in Nigeria. The study therefore investigates the level of consumers' satisfaction with adoption of e-payment system in Nigeria. Data for the study were elicited from bank customers and consumers of the product. Overall, the result indicates that fewer consumers were satisfied with the speed of transaction, level of service provided by the merchants, awareness, and security. These findings suggest opportunities for improving the consumers interface with POS technology in order to achieve the objective of cashless economy. Key words: e-payment, point of sale terminals, consumer

PRELIMINARY BIOAUTOGRAPHIC ANALYSIS OF THE SEEDS OF GLYPHAEA BREVIS (SPRENG) MONACHINO FOR ANTIOXIDANT AND ANTIBACTERIAL PRINCIPLES.

Glyphaea brevis (Spreng) Monachino (G. brevis) is widely distributed in West Africa with its various parts used in traditional medicine. In Sierra Leone, the leaves of the plant are used traditionally to enhance labour while the seeds are used in the treatment of skin infections. The present study is aimed at screening the seeds for phytochemical groups, antioxidant principles and antibacterial principles. The plant extracts were examined for phytochemical groups by standard spot tests. Chromatographic separation of seed extract was performedon reverse phase column and on silica at medium pressure chromatographic set-up. Thin layer chromatographic plates were visualised by UV light and vanillin sulphuric acid spray reagent. The crude extract and chromatographic fractions were examined for radical scavenging properties using 2, 2-diphenyl-1-picrylhydrazyl radical (DPPH). Antibacterial bioautographic evaluation was performed using B. subtilis NCTC 8236 as test organism and Methylthiazolyl tetrazolium chloride as detecting reagent. Phytochemical screening of the seeds of G. brevis indicated the presence of phenolics and saponins. Pink colour reaction of polar Thin Layer Chromatographic (TLC) spots with vanillin-sulphuric acid spray (V/SA) suggested the presence of terpenoid glycosides. Screening with DPPH showed prominent antioxidant spots on silica at Rf 0.8, 0.5, 0.4 Ethyl acetate (EtOAc). The three spots reacted purple to V/SA. Bioautographic analysis revealed antibacterial spots at Rf 0.8(EtOAc) and 0.7(EtOAC-MeOH, 9:1).The seeds of Glypheae brevis contain specific antioxidant and antibacterial principles which have been described by their chromatographic properties in this study

Living without the State: A Rear View Mirror of Nigeria\u27s 50 Years of Independence

The purpose of this analysis is twofold. First, it undertakes a critical review of Nigeria’s performance within the five decades of its nationhood. Second, it compares its performance vis-à-vis a number of new states which started almost at the same time in both Africa and Asia using basic economic and political indicators. The article, however, infers that Nigerian political-economic performance is appalling, which has subjected citizens to living almost without the state in all ramifications. For a balanced view, the analysis argues that although there are few giant strides in terms of educational development and reduction in infant mortality as a result of improved health facilities, the gap between intent and actual practices is still very wide. The analysis recommends that the policymakers should visualize the next five decades and formulate appropriate reforms so that Nigeria may not eventually become a failed state

Corrosion resistance of surface-conditioned 301 and 304 stainless steels by salt spray test

The corrosion rate of surface-conditioned 301 and 304 stainless steels (SS) was determined by salt spray test in a controlled accelerated corrosive medium (9.5 L of pure distilled water + 500 g NaCl). Surface conditioning via mechanical attrition treatment was firstly carried out before the salt spray test. The corrosion rate was determined by weight loss method before and after the salt spray test. Compared to the untreated 301 SS sample with a weight loss of 0.15 g, the surface-conditioned 301 SS samples treated for 300 s and 1200 s experienced a lower weight loss of 0.04 and 0.02 g, respectively. A similar reduction in weight loss was achieved for 304 SS sample when treated for 300, 600, and 1200 s

Analysis of Pattern and Extent of Deforestation in Akure Forest Reserve, Ondo State, Nigeria

Forest Reserves in Southwestern Nigeria have been threatened by urbanization and anthropogenic activities and the rate of deforestation is not known. This study examined the vegetation characteristics of Akure Forest Reserve using optical remote sensing data. It also assessed the changing pattern in the forest reserve between 1986 and 2017. Global Navigation Satellite System (GNSS) receiver was used to capture the location of the prominent settlements that surrounded the Forest Reserve in order to evaluate their effects on the forest. Landsat TM 1986, Landsat ETM+ 2002 and Landsat OLI_TIRS 2017 with 30m resolution were classified to assess the spatio-temporal changing pattern of the forest reserve. The results showed different composition of vegetation, which include undisturbed forest, secondary regrowth and farmlands. The study further revealed that in 1986, 2002 and 2017, undisturbed forest constituted 63.3%, 32.4% and 32.1% of the entire land area respectively, while secondary regrowth occupied 8.3% in 1986, 9.5% in 2002 and 15.6% in 2017. The farmlands had erratic growth between 1986 and 2017. It was 16.9% in 1986, 22.1% in 2002 and 17.5% in 2017. The bare ground exhibited inconsistency in the coverage. In 1986 the areal extent was 11.5%, when it increased to 36% in 2002 and decreased to 31.9% in 2017. In conclusion, the study revealed the extent of forest depletion at Akure Forest Reserve and it is therefore important that the residents, the government and the researchers show major concern about some of the critical factors to human beings that are responsible for forest depletion

Corrosion resistance of surface-conditioned 301 and 304 stainless steels by salt spray test

The corrosion rate of surface-conditioned 301 and 304 stainless steels (SS) was determined by salt spray test in a controlled accelerated corrosive medium (9.5 L of pure distilled water + 500 g NaCl). By surface conditioning via mechanical attrition treatment, a gradient-structured layer was firstly generated on the surface of the samples before the salt spray test. The corrosion rate was determined by the weight loss before and after the salt spray test. Compared to the untreated 301 SS sample with a weight loss of 0.15 g, the surface-conditioned samples treated for 300 s and 1200 s experienced a lower weight loss of 0.04 and 0.02 g, respectively. A similar reduction in weight loss was achieved for 304 SS sample when treated for 5, 10, and 20 mins

The effect of patient aggression on healthcare workers’ mental health and anxiety mediated by psychological well-being during the COVID-19 outbreak

oai:repository.canterbury.ac.uk:97017The aftermath effects including overstressed health systems, increased number of cases, death rates, and patient aggression have significant implications on the healthcare workers’ psychological well-being. Building on both the Health Belief Model and Conservation of Resources theory, this study examined the impact of patient aggression on healthcare workers’ psychological well-being, anxiety, and mental health during the COVID-19 pandemic. Further, the study tested the mediating role of psychological well-being in the abovementioned relationships. Data obtained from 549 Lebanese healthcare workers in private hospitals in a two-wave survey was used to evaluate the proposed study’s relationships, using confirmatory factor analysis and structural equation modeling. The results indicated that patient aggression has significant negative impact on healthcare workers’ psychological well-being and mental health while it increases anxiety. Further, psychological well-being partially mediated the relationship between patient aggression and anxiety. Theoretical contributions, practical implications of the study, and suggestions for further studies are discussed
