Abstract: Thailand is the world's largest exporter of canned pineapple, although 90% of production is produced for export that the cancellation of commercial privileges had an effect on competitiveness and supply chain, which were formerly vital. In 2018, manufacturers' severe pineapple overstock crisis, greatly affects the purchase price are directly impacted farmers' income. Therefore, this research aimed to analyze the cost management of pineapple production in 2017/18 during this crucial price situation by using a stochastic frontier approach of 388 pineapple farmers in Loei and Nong Khai Provinces in northeastern Thailand. The results showed that overproduction and the usage of fertilizers: Ammonium sulfate and 15-15-15 formula are lacks economy of scale. The surprisingly direction of the variable inefficiency coefficient in this unusual situation that increases the inefficiency are contacting with agricultural extension officers and using flower accelerator. It appears the average of cost-efficiency index only 0.146 indicated the farmers are unable to adjust their crop management and strategies sufficiently. Lastly, it should adequately inform farmers about the process of the circumstances. It is also necessary to mention hedging tools such as farmers' access to contact framing, improving agriculture cooperatives and farmers association, buffer funds, and agricultural price insurance to ensure resilience to any shocks.

Abstract: The aim of this study is to reveal the effects of using educational comics on students’ academic achievements, democratic attitudes, knowledge retention and students’ experiences about the teaching materials in the 6th grade social studies course “Participating in Administration” learning area. The research was carried out with mixed methods research and embedded design was used in the study. Mixed methods is a research approach whereby researchers collect both quantitative and qualitative data within the same study to understand research problems and integrate two data sets. Using the advantages of combining these two data sets, researchers draw conclusion on the strengths of these methods. Mixed methods research is used in the behavioural, health, and social sciences. The basic assumption of this approach is that it is more advantageous for the researcher to combine statistical trends (quantitative data) with personal experiences (qualitative data) than to use either of these methods alone to better understand the research problem. In an embedded design, both qualitative and quantitative data are collected at the same time, but one type of data, either qualitative or quantitative, is secondary to the other. Considering the findings obtained as a result of the analyses, it was found that there was a significant difference between the mean scores of experimental group students taught with educational comics and control group students in terms of academic achievement, democratic attitudes, and knowledge retention. According to the findings obtained from the interviews, it was revealed that students were pleased with the use of educational comics in online environments via distant learning and they evaluated these teaching materials as informative, entertaining, and attention grabbing. It was concluded that educational comics used in social studies course in distant education had positive effects on students’ academic achievements, democratic attitudes, and knowledge retention and the students found these teaching materials used in distant learning effective and positive.

Abstract: Resistance to already known antibiotics is a burning issue. Today, plant material is increasingly being tested with the aim of detecting pharmacologically active components. Watermelon seeds are most often discarded as waste, and bearing in mind that other parts of the watermelon contain a lot of bioactive components, the logical sequence is also the examination of the seed extract. The aim of this paper is to examine the content of bioactive components, antibiotic activity, minimum inhibitory concentration (MIC) as well as antibiofilm activity extracts of seeds of two species of watermelon, from Croatia and Greece, obtained from two different extraction methods, maceration and Soxhlet extraction. Phytochemical analysis was performed using three different HPLC methods. The antibacterial effect was done using disc method, MIC was determined using broth dilution method and biofilm formation was done using Tryptic Soy Broth (TSB). The results indicate the presence of some flavonoids in all samples, as well as on antimicrobial activity against certain strains of bacteria. The best result iwas shown by the ethanol extract from Greece and overall ethanol extracts show slightly better antimicrobial activity compared to methanol extracts. Depending on the tested concetration, different biofilm categories appear. The results show that as the extract concentration decreases, the biofilm formation capacity increases. Our data show that extracts of the seeds have the potential to act as antimicrobial agents, and further research is needed.

View Abstract Hide Abstract   |   Download PDF
Abstract: National statistics suggest that drop-out rates for first year students entering science, technology engineering and mathematics (STEM) programmes are disproportionately higher across all universities in South Africa. Predicting first-year student success in these programmes has thus become a priority area for researchers in the student academic support and development centres. This paper reports on the results of a pilot study that sought to draw inferences about the predictive value of the Test of Academic Literacy Levels (TALL) at one university of technology in South Africa. The purpose of this test is to inform academic staff of entry profiles of students and to assign students to tutorial groups and other academic support programmes. TALL was meant to be written by all new students taking mathematics and science courses in the years 2015 (n = 1240) and 2016 (n = 2133). The findings indicate poor performance for most students who took the test. The findings indicate that the test is not adequate for predicting future academic performance of first year students at tertiary institutions. The results of the current study have informed the University about the diagnostic value of the tool and the academic profile of students which subsequently lead to improved student academic support initiatives.

Abstract: This study sought to investigate school district and teacher related barriers to continuous professional learning and development through university education in the Elliotdale Circuit of the Dutywa Education District, South Africa. The research was a qualitative study based on Bioecological Model of Human Development Theory. A sample size of twenty-two (22) respondents (principals, teachers and subject advisors) was used. Face-to-face in-depth individual interviews were conducted using an open-ended interview schedule. Data were analysed thematically. The study found the following to be the barriers to teacher continuous professional learning and development through university education in the Elliotdale Circuit: long hours of travel to and from school by teachers, long distance between the Elliotdale Circuit and cities where Higher Education Institution are situated, deprived and underdeveloped nature of the circuit, teacher workload, insufficient time for further studies, inadequate support from the education district, inadequate information on sources of financial support and bursaries, laziness on the part of teachers and teachers’ self-sufficiency with their current qualifications. Recommendations made were that the Department of Education should make provisions for continuous self-improvement of all teachers in the circuit; the Education Circuit should work with all school principals to support teachers financially to embark on further studies. School Management Teams should work hand in hand with the District Education to organize career guidance workshop for all teachers focusing on the need for teachers to move from their comfort zones and to upgrade their teaching qualifications in the education system.
