This research aimed to study the use of coarse aggregate obtained from removing old recycled asphalt pavement (RAP) in the production of the porous concrete paving block. Crushing and size separation of the coarse aggregate by using standard sieve size by selected the gradation size of the coarse aggregate that passed to sieve size 1/2” and retained on sieve size 3/8” and other that passed to sieve size 3/8” and retained on sieve size No.4 by mixing ratio 50 : 50 of the mass as replaced natural coarse aggregate. Portland cement quantity about 18% and 20% by weight of the aggregate. The water to cement ratio was 0.30 and 0.35 respectively. Compressive strength flexural strength and water permeability were investigated. The results showed that the cement content and water to cement ratio was influenced the strength properties and water permeability rate of the porous concrete paving block. The porous concrete paving block mixed with higher cement content (20%) had the compressive strength at the age of 28 days increased by 16-24% when compared with lower cement content (18%). On the other hand the water permeability rate decreased by 5.1-8.1%.

In conducting the research on Material Science two composite materials ultra high molecular weight polyethylene (UHMWPE) powder and aluminum oxide (Al2O3) powder were formulated by hot compression molding process. The formulated materials demonstrated good mechanical properties and high wear resistance properties. Based on the studies the Al2O3 grade selected was Al2O3 HTM 30 harboring mixed uneven powder particle sizes ranging from 2 to 5 microns (μm) and selected proportion of Al2O3 alloy mixed for improving mechanical and wear resistance properties of the UHMWPE composite material was the UHMWPE+Al2O3 HTM 30 at a ratio of 95:5%. When considering both material properties and cost effectiveness in the impact test 2-5 μm Al2O3 HTM carried the higher impact strength than other aluminum oxide grades with the values up to 586.8 J/m at a ratio of 5% aluminum oxide. The hardness test of the 2-5 μm UHMWPE+ Al2O3 HTM delivered the hardness at 58.8 using the standard durometer. The tensile test values consisted of Yield Strength Ultimate Tensile Strength Breaking Strength Elongation at Break and Modulus of elasticity equal to 20.52 MPa 29.96 MPa 22.83 MPa 265.8% and 784.46 MPa respectively.

Admission to higher education By students who come to study later from different institutions Different residence But have to live in the same university Which must meet An environment with a difference Social trends or values of the current society that have Quick change Friends that have a wide variety of family and social basics are also popular. The lifestyle which students who come to study in the Faculty of Engineering must have patience there is discipline and responsibility; there is morality ethics and sacrifice. Therefore it will succeed as a good and qualified engineer. Creative recruitment process it is considered that it is important to the lifestyle of a new group of students to have the opportunity to build a good relationship with their studies in engineering. Able to develop good relationship in future career in engineer A creative approach to recruiting to build relationships towards engineering studies. By organizing seminars to guide creative recruiting from people related to students Which consists of administrators teachers And staff of the Faculty of Engineering the objective of the official recruitment is creatively to find ways to create creative recruiting in the Faculty of Engineering and to create positive values for the Faculty of Engineering students. So that students are conscious of building a good relationship to study engineering.

This research aims to develop the guidelines of an automated educational recommending system through various social media in form of chat robots (Chatbot). This is under the assumption that the Chatbot can assist the human workload in responding to Students’ frequently asked questions (FAQ). With the Chatbot inquirer students would be responded in fast and accurate to the inquiries. The prototype of this system is built on the Dialogflow platform to connect to the Line Application. The prototype was tested via users and received “good” level of the overall user’s satisfaction.

The health care industry is one of the rapid growth industries in Thailand. Thai government has promoted and set a strategic policy to by “Medical Hub of Asia”since 2004. Therefore the chief executive officers of many hospitals have determined strategies to improve their service quality because of the global competition. Service competition. Service quality which refers to customer perceptions of the service process has been considered. Sansei Engineering can be the best tool for translating customer perceptions and emotions to the psychical desire attributes. This study conducted sansei engineering and service quality to analyze the relationships between service quality and customer’s emotion and feeling. The decision making trial and evaluation laboratory (DEMATEL) was employed to constructs the cause-effect relationship of criteria of the model that can be described complexity of causal relationships. The results show that tangible and empathy are the key factors that should be considered as the first priority for improving by public hospitals directors.
