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.
Technology Reports of Kansai University (ISSN: 04532198) is a peer-reviewed journal. The journal covers all sort of engineering topic as well as mathematics and physics. the journal's scopes are
in the following fields but not limited to:
Gedi (Abelmoschus manihot L.) is a tropical plant in the Malvacea family that is used as food and medicinal/herbal plant? This shrub can be found in Sulawesi, Maluku, Nusa Tenggara Barat dan Papua. The objective of this study was to determine the parameters to obtain an optimal extraction yield. As parts of ultrasonic extraction method, the parameters tested were ratios of dried Gedi leaf powder to ethanol and time of sonication. Gedi leaves from North Sulawesi was dried in an oven at 70oC for five hours and followed by grinding and sieving with 40-mesh siever. The first phase of the study was testing different solution ratios (m/v) of 1:10, 1:20, 1:30, 1:40, and 1:50 at a constant time of extraction of 30 minutes. The second phase was varying the time of sonication at 5, 10, 15, 20, and 30 minutes at the constant solution ratio of 1:40 (m/v). Throughout the study, the ultrasonic wavelength was set at 40 kHz and the temperature on the water bath for concentrating the Gedi leaf extract was set at 50 - 60oC. The optimal yields from both phases were 9.866% for the parameters of 1:40 (m/v) ratio and 30-minute sonication. Further analyses of Gedi leaf extract produced antioxidant effectiveness of 86.77% and phenolic content of 24.34 𝜇g/mg
Pedestrian safety becomes one of the serious problems in transportation systems. As the number of vehicles is growing, the levels of traffic accidents have increased significantly, Vehicle and pedestrian collisions often result in fatality to the vulnerable road users. This study aimed to review and analyses literature related to vehicle-to-pedestrian communication and classified the existing technology for Vehicle to pedestrian communication. The factors that were considered to improve understanding of the field’s various contextual aspects in published studies and characteristics were substantial analysis that confronted researchers and proposes a new direction for pedestrian safety to enhance this vital research area. We systematically searched all articles about vehicle to pedestrian communication in three main databases: Science Direct, Web of Science and IEEE Explore from 2008 to 2020. These indices were considered to be sufficiently extensive to encompass our field of literature. Based on our inclusion and exclusion criteria, 56 articles were selected. Most studies (29/56) focused on the development system, a number of papers (20/56) covered the study conduct on analysis, evaluation, and comparison, few papers (4/56) presented survey and overview studies. The last smallest portion (3/56) of papers study framework systems for V2P communication. Vehicle-to-pedestrian communication, which is a field requiring automated solutions, tools, and methods, entails the ability to facilitate detection or even prediction. Many studies have been performed on the detection and enhance data exchange of V2P to promote pedestrian safety. The research area's vehicle-to-pedestrian communication vary, but they are all equally dynamic. We expect this systematic review to help emphasize current research opportunities and thus extend and create additional research fields. A proposed research methodology as a new direction is provided to solve the gaps identified in the analysis. This methodology consists of four phases; Investigation Phase, design a framework for the pedestrian safety system, Study and Analysis, and evaluation phase. However, research areas on V2P communication with the scope of data exchange are varied. This systematic review is expected to open opportunities for researchers and encourage them to work on the identified gaps.
