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.

In the event of natural or manmade disaster, clean water might be a very precious commodity. Commercial water treatment tablet might be able to purify water but it might also poses health hazard when consumed in large amount. This research focused on the development of naturally derived water treatment tablet formed from the leaves and oil extracted from the seeds of Moringa Oleifera and activated carbon (from coconut shells). The characterization of the activated carbon and Moringa Oleifera was carried out by Fourier Transform Infrared Spectroscopy (FTIR), X-ray diffraction (XRD) and Brunauer, Emmett and Teller (BET), while the efficiency of water treatment tablet was analysed by Turbidity Meter. FTIR results shows that there are hydroxyl groups and carboxylic group in the activated carbon sample which correlates well with literatures. XRD results indicated that both activated carbon and Moringa Oleifera was amorphous in structure which might facilitates towards the dynamicity of the water treatment process. BET’s results shows that activated carbon have larger surface area compared to Moringa Oleifera leaves. The results obtained from turbidity meter analysis showed that the existence of Moringa Oleifera oil contributes toward better water treatment capability while the leaves of Moringa Oleifera on its own was less effective as water treatment agent. It can be concluded that the combination of Moringa Oleifera oil and leaves with activated carbon at a ratio of 125:50:250 (in mg) can be considered effective in removing impurities from water where 59.22% of the contaminant was successfully removed
The study sought to investigate effective teaching and learning strategies appropriate for Grade 4 mathematics learners in solving addition and subtraction of word problems in some selected schools in the Thaba Nchu District, Free State, South Africa. Six participant teachers were observed during teaching and learning. Purposive as well as random sampling techniques were utilised for the study to select thirty mathematics teachers from six schools. At least four teachers from each school were randomly selected for the quantitative part and six teachers, one from each school were selected purposively for classroom observation. Six Grade 4 classes were observed and were chosen purposively based on the cluster sampling technique, three using English as a home language and three schools using English as a second language. Quantitative data were analysed using frequencies and percentages whilst qualitative analysis was conducted through content analysis. The findings of the study revealed that educators used teacher-centred method rather than learner-centred in teaching and was found not to support Grade 4 learners in addition and subtraction of word problems. However, the study also revealed that teachers used some alternate teaching strategies to support learners in the learning of addition and subtraction of word problems, which included teaching learners about reflection when solving problems, asking learners to explain and justify their claims, and code-switching. Furthermore, the study revealed that educators enjoyed using physical objects like cardboard and practical work in teaching and learning of addition and subtraction in word problems. Recommendations were made concerning the above findings
