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.

Software design is described as the process of defining the architecture, components, interfaces, and other characteristics of a system or component plus the result of the process that births the design with an overall aim of creating the architecture on which the software will run. However, software designers are faced with numerous concerns during system design. This work discussed basic concerns namely security, modularity, performance and re-usability. Each of the issues were briefly and separately analysed to understand the intricacies. It was revealed that the use of models, understanding and predicting computers’ future, excellent system structuring control modeling, and modular decomposition are some of the solutions to the issues raised. Conclusively, since humans are still susceptible to errors and to adequately alleviate the impact of such during designs, designers and experts generally must understand high-level design concepts. The best architects don’t have to know how to implement all levels of design they only need an understanding of all the levels.
In the Vivo of corrosion of the cobalt-chromium-molybdenum defined by (CoCrMo) alloy and its prospective opposing effect on the body are recognized as a critical concern regarding using as a biomaterial for biomedical applications for years. The underlying mechanism of the mechanical and general assisted corrosion (MAC) associated with some biomedical applications, such as orthopedic implants, are extensively studied and documented. These studies are focused on the effect of wear particles and ions of metal on the biological response. However, some researches have been reported some inflammatory issues due to metal corrosion used for CoCrMo implants. This challenge has to change the way of understanding the relationship between corrosion and biological system, which is called ―corrosion causes biological responses‖. This article introduces a brief review on the Vivo corrosion of implants manufactured from CoCrMo. The major part will be focusing on the inflammatory cell-induced corrosion (ICIC) and the new viewpoint about the 2-way feedback loop between the human body and corrosion. Recent recovery researches on ICIC and its clinical importance are going to be explained. The species of reactive chemicals, biological elements, and electrochemistry associated with the ICIC underlying mechanism are going to be shown as well.
In this paper, we examine the foggaras of the oasis of Ezzaouia in the region of in Salah. During our visit to the oases of in Ghar during the year: 2013-2019, we discovered in the small oasis of Ezzaouia located 2 kilometers southwest of the oasis of in Ghar, a system of millennial irrigation composed of 5 foggaras. After surveys of the owners of the foggaras and the hydraulic services, we concluded that this heritage has never been the subject of an inventory. According to our surveys among foggaras owners, the total flow rate of these foggaras is around 50 l/min for a total length of the gallery equal to 1.5 kilometers. Unlike the foggaras of in Ghar, which capture the waters of the Intercalary Continental, those of the Ezzaouia oasis capture the waters of the Erg Ezzaouia.
Landslide disaster is a geological event because the mass of rock or soil undergoes changes or movements such as falls and shifts from its original position. Meanwhile, landslides are a natural disaster that often occurs in Indonesia, this is Indonesia is an area prone to earthquakes, because Indonesia is a meeting point between three active tectonic plates, namely the Indo-Australian plate, the Eurasian plate and the Pacific plate. This research only focus to analysis rockfall types landslides, this type of landslide often occurs in rock areas, East Nusa Tenggara Province. The method used to analyze the effectiveness of rockfall type lanslide handling is to calculate the largest volume of rock that has the potential to fall by using kinematic analysis so that the handling used can function optimally. The result of analysis, it is known that in one layer of landslide plane, several alternatives can be used for different number and distance of nailing, which are calculated based on the estimated maximum load of the fallen rock, so that the use of wire mesh can be more effective.
In this study, we focus on the commerce students’ ability to correctly apply integration rules. This was in the context of online learning during the Covid-19 lockdown at a university. Students were provided with recorded lectures on integration rules and their applications. They were then given tutorial problems to work on and they could discuss their difficulties or queries with their tutors. An online quiz was designed to focus on questions which assessed their ability to apply some techniques of integration such as direct integration, 𝑢-substitution, integration by parts, area between given curves, and interpretation of word problems involving integration. We then used their responses to that online quiz to determine the performance level of the students (n = 590). The statistics based on their responses were then looked at. Based on the statistics we invited all the students to take a questionnaire. Also, we gave a written task interview to some of these students to get feedback based on the items covered in the quiz. The written task interview responses of six students were then used to obtain an insight into the online responses of participants. It was found that the majority of the students were able to adequately apply the direct integration, 𝑢-substitution techniques and area under the curve. In particular students had difficulty with integration by parts and the word problem whose modeling required the setting up of an indefinite integral.
