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.

The European Union (EU) has recently established maximum limits for Ochratoxin A (OTA) in roasted and soluble coffee as well as for green coffee. Some countries have already established national limits for OTA in green coffee. Cup quality is a complex characteristic which depends on a series of factors such as the species or variety, environmental conditions, agronomical practices, processing systems, storage conditions, industrial processing, beverage preparation and taste of the consumer. This research was carried out to assess coffee storage & warehousing operations along the supply chain coffee from farmers/ cooperative warehouse up to Ethiopian Commodity Exchange (ECX) and Ethiopian Agricultural Commodities Warehouse Service Enterprise (EACWSE) branch warehouse as a case study in Sidama & Gedio Zones. The study employed descriptive analysis in assessing warehousing practices and problems of Coffee supply chain. Site observations and semi structured research were employed as research data collection. Interview questions were sent to various stakeholders, who gave their views on various warehousing practices and problems in accordance with how such problems impacted or influence their work. All the warehouses are substandard. The warehouses situations accelerate quality deteriorations due to moisture loss. This condition creates disputes and source of conflict because of coffee weight loss and compensation schemes between the top management and store managers. The field result demonstrates a lower level of material handling equipment uses. The warehouse operations are highly labour based. It was recommended that there should be effective strategy in adopting the FIFO principle, regulating trucks, introduction of weighbridge to speed up offloading process at the warehouses. The Coffee production and distribution traceability need to be supported by information communication technologies such as RFID
Non-singular matrices have a key role to play when determining the rank of a matrix. The rank of a matrix is useful when deducing the nature of solutions to a system of linear equations. In this paper I report on a qualitative case study which explored possible mathematical gaps that created barrier/s when engineering students (n=101) worked with the rank of matrices to determine the nature of the solutions of a system of linear equations. These engineering students were provided with two tasks and their written responses were used to detect possible barriers in their understanding of the rank concept. The study was carried out at a University of Technology in South Africa. The data, which was collected from written responses of students to two tasks, were analysed using APOS theory. Interviews followed these analyses to verify the APOS levels they were placed at. Findings emanating from the data analysis indicated that we: 1) can correctly place the APO level of conception of an individual if the individual provides a completely mathematically correct solution, 2) cannot be certain at which mental construction an individual is performing at when partially mathematically correct responses are provided and 3) individuals providing completely incorrect solutions require further exploration.
