Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

This research aimed to identify, to compare, and to analyse the correlation of the taxonomic structure of 4th grade elementary student’s electronic textbooks which referred to the 2013 curriculum. The object of this research was the text books published in 2014 and 2017, focusing on the test section. Taxonomic identification was carried out based on Bloom taxonomy, including six levels of operational words, such as remembering (C1), understanding (C2), application (C3), analysis (C4), evaluation (C5), and creation (C6). Identification was carried out for all taxonomic groups. Data analysis was carried out descriptively. Comparison between text books was analysed statistically using chi-square test, while correlation analysis was carried out by Pearson’s correlation. The result showed that the 2014 text book had more question items than the 2017 text book with 1061 items and 688 items respectively. There were total of 3260 and 1756 taxonomic content respectively, resulting in average number of 3.1 and 2.6 taxonomic items in each question. Both text books showed similar trend in numbers of taxonomic items as the increase of taxonomic levels. Statistical data analysis showed that there was significant difference of taxonomic structure between the 2014 and 2017 text books. Significant differences were obtained from the C1 and C3 levels, whereas the proportion of C1 in the 2017 text book was significantly lower while the proportion of C3 was significantly higher. However, correlation analysis showed that the taxonomic structure of both text books was strongly correlated
The ethyl acetate extract of Musa paradisiaca L. leaves contains quercetin. The main problem of quercetin associated with oral administration is its poor aqueous solubility. Nano emulsion is drug delivery system that it was prove to enhancement the solubility and permeation of lipophilic drugs. The research aimed to investigate nano emulsion as carrier of extract to improve the activity of antioxidant and antibacterial. The nano emulsion of extract was formulated by various concentration of Tween-80 and PEG-400, and it was optimized by Factorial Design on Design Expert®7 software based on desirability value. Design using response droplet size, zeta potential, and pH. The optimum formula selected was tested for physical stability and activity. Physical stability was tested by centrifugation and cyling test methods. The antioxidant and antibacterial activity of fo and extract were determined by DPPH and Kirby Bauer methods, respectively, and its analyzed by independent T-test. The optimum formula was obtained by 15% Tween-80 and 10% PEG-400 with desirability value 82,4%. It has pH 6.4, droplet size 15.3 nm, a polydisperse index (PI) 0.012, a zeta potential -23.3 mV. Physical stability test shows the formula does not experience syneresis, separation, creaming or cracking. The independent T-test showed that nano emulsion significantly improved antioxidant and antibacterial activities against S. Aureus and E. Coli with p value 0.001, 0.003, and 0.000 respectively. The results prove that Nano emulsion is potential for improving lipophilic drugs
