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.

Glass's is a building material that was recognised in the 1940s, and advancements proceeded with the inclusion of zirconium dioxide in the 1960s for hard alkali environments. To improve material durability, glass fibres of a new generation is being developed. As a result, the production of glass fibre reinforced concrete (GFRC) began to meet various demands in addition to the technique of ultra-thin glass fiber reinforced concrete components and assemblies. Scientific research and testing on GFRC. the main objective of ultra-thin glass fiber reinforced concrete components and assemblies.is to rethink the usage of ordinary concrete in buildings, which is frequently seen as a hefty and compressive structural material through premixed GFRC is cast in polyethylene bags as we will see during the experiment in this paper. As technology progresses, it is possible that the entire building and complicated freeform will be built at a reasonable cost. During the last several years, The influence of glass fibres in hybrid mixes has been studied for high-performance concrete (HPC), a developing technology that has gained popularity in the building sector to can get on developed GFRC called ultra-thin glass fiber reinforced concrete.
An experimental laboratory was conducted to treat produced water by kapok fiber adsorbent, activated using sodium hydroxide (NaOH) 5% wt. and hot water at 100 0C followed by ultrafiltration membrane to reduce total dissolved solids (TDS), barium, and phenol concentration. The research variables were operating times of 30, 60, and 90 min, and the flow rate of produced water samples was 5 L/min, 6 L/min, and 7 L/min. The scanning electron microscope (SEM-EDX) investigated the kapok fiber's surface. The results showed that the decrease in TDS, barium, and phenol by activated kapok fibers was 52.8%, 66.77%, 72.55%, respectively. Further, filtrate treatment from kapok fibers column in ultrafiltration membranes (UF) showed the removal of TDS, barium, and phenol removal achieved 43.12%, 99.76%, and 42.44% at a feed flow rate of 5 L/min and operation time of 90 min. The total removal for the currently proposed system is 95.91% TDS, 99.92% barium, and 84.20% phenol. Produced water pretreatment using kapok fibers absorbent followed by UF membrane reduce TDS, barium, and phenol concentration from produced water. Finally, the permeates of the ultrafiltration membrane followed Indonesian standards for wastewater quality.
Sending important information over the Internet has become a norm nowadays. Protection must be done so that information is not easily hacked and misused. Steganography is one of protection method in which hidden information is inserted into a digital multimedia channel. This paper aims to hide image messages into audio files with different formats using the Least Significant Bit (LSB) and Discrete Cosine Transform (DCT) approaches. We conducted a performance test by measuring the Peak Signal to Noise Ratio (PSNR), endurance to compression, and transparency of the host that has been inserted the message. The results showed that the PSNR value of audio files through the DCT process was greater than that of LSB, subjective assessment of the mean opinion score related to audio files through the LSB process was better than DCT, and all audio files did not have resistance to a compression mode.
This study aims at investigating the service quality and customer satisfaction in automobile aftersales services, using the SERVQUAL Model. The study examined the variables that affect the customers’ satisfaction in aftersales service centers, and assess the service quality using the SERVQUAL model. The study employs a quantitative research approach, by developing and distributing two questionnaires to a sample of 250 respondents to assess service quality and customer satisfaction in the automobile industry. The research mainly found that some service centers need to put more effort and emphasis to enhance the assurance, reliability, empathy, and tangibles dimensions. It is noted that people in all of the targeted service centers are expecting the service providers to invest more in the tangibles, and to install more visually attractive physical materials and facilities. Being the first in this field, the outcomes of this study shall be used as a reference to advance and enhance the automobile aftersales sector in the future, and support car dealers and service centers in improving the quality of their offered services to ensure customers’ optimal satisfaction.
Globally due to the urbanization and the population growth in the urban centers, the problems of short come of resources, economics, and the need for high density dwellings arise. The idea of high density housing in the form of small communities arise as a solution to overcome the short come of dwellings and to provide shelter for great numbers of people on a smaller areas of land. This trend has shown up in Kurdistan region of Iraq from the beginning of 2000s, which makes an important topic of interest and necessary to be investigated to guarantee the life and wellbeing of the residents living in these communities, and this is why this paper is trying to analyze the spatial planning of the layouts and the use of public spaces in these communities (Darwaza city as a case study), because the use of public spaces mainly affects the social interaction of the residents, and the vitality of these spaces and positive interaction affects the well-being and psychology of the residents. Many fields of psychology, social sciences, and many urban researchers tried to investigate and understand the relation between built environment and human through many theoretical concepts, and evaluative methods to draw conclusion that promote the use of these public spaces. This paper tried to use space syntax as a theoretical framework and an analytical method using Depthmap program, because it is proven that space syntax is able to analyze quantitatively the relationship between people’s behavior and spatial configuration, and this study tries to overlap the results of people use of space obtained from direct observation and the analysis of the spatial configuration obtained from space syntax. The analysis shows interesting results of people’s use of space and correlations between space use and syntactical variables.
