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 objective of this article is to identify the determinants that influence high school students when choosing a university career, evaluating the effect of personal, family, and institutional factors. For this, a scale has been designed, initially validated by means of a focus group, which made it possible to measure the reasons for choosing university studies in young people in Medellín. Surveys were applied to 139 high school students, aged between 16 and 20 years. The results indicated that the factors with the greatest incidence in their choices were those related to the quality of academic programs and the future job possibilities derived from this choice, while the geographical location or the university campus were not considered as a priority for most of the respondents. Finally, the role of parents is highlighted; they are actors who exert a greater influence on decision-making when choosing a university career.
Aluminum Matrix Composites (AMCs) have been used in several applications in aerospace and automotive industries. Although several technical challenges exist with casting technology. Achieving a uniform distribution of reinforcement within the matrix is one such challenge, which affects directly on the properties and quality of composite. Hence, this work aims to improve the mechanical and corrosive resistance of aluminum by reinforcing with yttrium oxide and nickel through stir casting using vortex technique. Al-Ni- Y2O3 composite with the percentage of Ni fixed at 20 % and Y2O3differed through 3-9% in increments of 3 wt.%. The hardness value of the aluminum matrix composite improved with increased percentages of Y2O3, and the maximum increase was obtained for 9% Y2O3 composite, viewing an increase of about 52%. Potentiostatic polarization test for the Al-20%Ni base alloy and the prepared composite were carried out in 3.5wt% NaCl solution as corrosive medium. There was a noticeable improvement in the corrosion resistance of the aluminum composite compared to its purest form, owing to the presences of nickel. However, the increase in Y2O3 percentage decreased the corrosion rates. The extreme decrease in corrosion rates was obtained for 6% Y2O3 composite in 3% wt. NaCl solution which reach to 5.51 in (mpy) unit for composite material which is lower than that of the base alloy 118.59 (mpy).
