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.

Security system is implemented to conceal sensitive text-information on personal computer (PC). It offers using normal multimedia image-based steganography to substitute the pixel least significant bits with text to be hidden. The paper includes various testing setups for possible increment in the ambiguity and capacity within steganography adopting choices of 1, 2, 3 and 4 least significant bits stego-systems. The design novelty is based on offering full security data for the user for selecting suitable cover-image from the PC in terms of the security priority. This method permits the PC user to examine multi-bits steganography on various pictures for concealing similar sensitive texts. Then, it becomes possible for the user to prefer one image for using as cover image in terms of his/her choice understanding the desired capacity and security importance. The study proofs the information dependence and its security property by testing 24 fixed sizes PC pictures indicating remarkable outcomes
Using natural fibres like Sansevieria trifasciata can be an option to reduce energy consumption compared to synthetic fibre that requires a high consumption of energy since it contributes to the mechanical properties of composites. Therefore, an observation was done to know the effect of alkaline treatment with 3% NaOH on Sansevieria trifasciata fibre obtained through mechanical retting method, in which the composites consist of Sansevieria trifasciata with vinyl ester matrix. In this study, the modified fibre orientations were the random and the unidirectional ones, while the volume fraction used was 0%, 5%, 10%, and 15%. Several tests were carried out namely tensile tests, impact tests, density tests and observations through scanning electron microscopy (SEM). The results of this study found that the value of tensile strength could increase up to 31.7%, the stiffness could increase up to 13% and the toughness could increase 49.6% with the addition of alkaline treatment on the fibre. There was also an increase in mechanical properties with the addition of volume friction, in which the largest increase occurred in the volume fraction of 15%
