Burnout Syndrome During the Covid-19 Pandemic among Visual Art Teachers in Ghana

This study sought to address burnout syndrome during the COVID-19 global pandemic among visual art teachers in Ghana. The startling intricacies of COVID-19 burnout among Visual Art Teachers (VAT) in Ghana were discovered using an exploratory research approach. 112 participants were surveyed across Senior High Schools Visual Art Teachers in Ghana. Data were analyzed using t-test, regression, and analysis of variance test (F test) to determine whether there were significant differences between the burnout levels and demographic factors. The findings revealed that, the only effects of the burnout that are statistically significant on gender are reduction in productivity or efficacy in teaching difference (t=-4.41, p=0.00(p<0.05)), Sleep disorders (t= -3.22, p=0.02(p<0.05)), short temper (t=-2.84, p=0.006(p<0.05)) and health consequences (t=3.36, p=0.001(p<0.05)). The ANOVA was significant between burnout negative effect among education level F (3, 108) =2.983, p= .035. However, the ANOVA was insignificant between burnout causes, effects, and preventive strategies scores and the ages of the teachers. The findings revealed that the majority of suggestions for burnout prevention fall under the category of personal changes. The study contends that though job responsibilities are high, the primary idea is that individuals have a larger role to play in preventing burnout.

Washing and Chopping Pre-treatment Effect of Vetiver Roots on Vetiver Oil Yield and Distillation Time

Vetiver is a type of grass mainly used for its roots to be extracted into vetiver oil. Despite the increasing market demand, the productivity of vetiver oil in Indonesia still consider low. One of the determinant factors of the extraction yield is the pre-treatment before distillation. This study aimed to determine the best pre-treatment method to improve the vetiver oil extraction using water and steam distillation by looking at the yield, distillation rate, and forecasted distillation duration. The distillation process was using water and steam distillation method for 9 hours. The data analysis method used Durbin-Watson autocorrelation analysis. The feasibility test of polynomial regression was modelled with the F test and ANOVA variance test. The result showed that the combination of washing 2-3 times and chopping pre-treatments of vetiver roots with a size of ± 5 cm could significantly increase the extracted vetiver oil by producing the highest yield (0.36% (wet-based) and 0.47% (dry based)), the highest extraction rate (0.057%/h) and the fastest forecasted duration of the distillation (10.5 hours). The combination of washing and chopping pre-treatments of vetiver roots was the best method and could be an economical solution for low productivity problems of vetiver oil in Indonesia.

Analysis of student learning outcomes’ standards in lecturers in the perspective of a disruptive era

In several universities in Indonesia, lecturers are accustomed to developing learning outcomes’ standards without the involvement of students in the formulation, although the students have many ideas about learning outcomes that are relevant to their needs. This study aimed to analyse the student learning outcomes’ standards in a disruptive era based on the students’ perspective from 9 faculties of several universities in Indonesia. The research method used was a quantitative approach, with 1059 student participants. Data were collected using a questionnaire with close-ended questions, and normality was analysed using the Shapiro–Wilk test and one-way analysis of variance test to determine the differences in learning outcomes’ standards between faculties. The achievements of disruptive learning at several universities in Indonesia are relatively high. However, there is an extreme distance in the level of disruptive learning achievement between faculties, due to the diversity of lecturers in understanding disruptive learning. Keywords: Learning outcomes’ standards, disruptive era, faculties

This study aimed to analyze English as a Foreign Language (EFL) students’ knowledge and perceptions of research method courses in the Department of English Language and Literature, at Imam Mohammad Ibn Saud Islamic University (IMSIU). It also investigated the problems that students encounter and offered some suggestions for improving these courses. The significance of the study is that such topic has never been investigated before in such context. The study participants were 1,022 students (Levels three, four, five, six and seven) who voluntarily filled out a questionnaire consisting of sections on four factors/themes: knowledge, perceptions, problems, and suggestions. The collected data were analyzed using IBM SPSS Statistics software to compare the students’ answers, and a one-way analysis of variance test was used to detect the differences between academic levels regarding each theme. The results showed that regardless of the students’ academic levels, all of them agreed on studying and therefore knowing the research basic components; however, regarding the elements constituting each of these basic components, significant differences were found between the five groups. The results also indicated that these students have positive perceptions of the courses even though they encountered some research-related problems such as in knowing all or some research basic components and their specific elements; writing all or some of them; citing, summarizing, and paraphrasing sources; allocating primary and secondary resources; collecting and analyzing data; and consulting research manuals. Finally, all students agreed that it would be helpful if they were assigned individual research supervisors and coauthored an article with them, a research course was taught in all academic levels for a bachelor’s degree, a research club was established, and research seminars were held.

Efficacy of Handpiece Mounted Continuous Irrigation System for the Removal of Residual Pulpal Debris During Root Canal Preparation

Objective The removal of residual pulpal debris (RPD) from the root canal walls, especially in necrotic teeth is important for successful endodontic outcome. The aim of this study was to evaluate the RPD removal efficacy of handpiece mounted continuous irrigation with simultaneous root canal preparation from the apical third of root canals as compared to conventional syringe irrigation (SI). Materials and Methods Ninety extracted teeth were randomly divided into three groups: SI; handpiece mounted continuous irrigation (CI); and both syringe and continuous irrigation (CI+SI). After root canal preparation, roots were sectioned at 1 (a), 3 (b) and 5 (c) mm from apex and prepared for Hematoxylin-Eosin staining. Sections were microscopically examined for presence of RPD. Statistical Analysis Intergroup difference in average percentage of RPD at different root levels was calculated by using analysis of variance test (ANOVA). Tuckey test was used for pairwise comparison. Results ANOVA showed significant difference between all three groups (p < 0.05). SI group showed a significantly higher percentage of RPD as compared with CI and CI+ SI groups at all root levels (p < 0.01). At root level a, CI showed a significantly higher percentage of RPD as compared with CI+SI (p < 0.01). Conclusion Handpiece mounted CI during rotary instrumentation showed a significant reduction in RPD as compared with conventional syringe irrigation. This technique was found to be an effective method for an enhanced root canal debridement.

The inhibiting effect of microwave radiation on Paenibacillus larvae spores suspended in water

The aim of this paper was to investigate the effects of microwave radiation on the viability of Paenibacillus larvae spores and to study the relationship between the microwave power consumption, the exposure time and the number of spores in the examined suspensions. Sterile distilled water suspensions were made using larval detritus, to contain tens, hundreds and thousands of spores. The suspensions of all the dilutions were gradually exposed to a microwave radiation power of 170, 510 and 850 W. In all the cases, the exposure time was 1, 2, 3, 4, 5, 10, 15, 20, 25 and 30 minutes. After cooling, 0.1 ml of each exposed suspension was inoculated onto three modified MYP (mannitol egg yolk polymyxin) agar plates and incubated aerobically at 37 ± 1 °C for 120 hours. The statistical evaluation of the spore counts decreasing with time was performed with the use of the nonparametric Friedman’s variance test using the Unistat Statistical Package v6.5. The results showed that the rate of devitalisation of the spores is dependent on the microwave oven power consumption, but independent of the number of spores. Using a power consumption of 170, 510 and 850 W, the devitalisation of the spores occurred after 15, 3 and 2 min of exposure, respectively.
