An Approach to Development of Manufacturing Data Report According to International Standards

The research purposes to design, analyze and build a report (MDR) integrity. To use as the MDR prototype in accordance with international standards for industrial factories. The MDR is important to the operator of equipment, the factories, and petrochemical industry because of it is an index for the quality assurance, quality control of fabrication and planning of maintenance management (material upgrade/ equipment change) for safety during equipment operation. When the equipment has a problem we can check for cause from the fabrication history data on MDR. A survey was developed for people concerned with the MDR, totaling 141 people from 58 factories in Thailand industrial sector for find out the demands and problems on using the MDR. The result shows that preparation of the MDR can cost more than a week of time, with no clear pattern of standard format and require manpower more than 3 peoples. In summary, the development of the MDR prototype by comparative data between, the manufacturer, the Ministry of Industry of Thailand and the American Society of Mechanical Engineers (ASME). The specialists who have the experience in the MDR to determine the completeness and validate all content in the MDR 15 chapters.</jats:p

รายงานวิจัย -- มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร, 2562The research project on The potential of Siphonodon celastrineus Griff, traditional medicinal plants of Thailand for treatment from local wisdom knowledge lead to the development of sustainable use, with the objective of studying the botanical, phytochemical, and biological activity of the Siphonodon celastrineus to create confidence in the use of S. celastrineus in herbal medicine by using the bark, leaves and fruit of the S. celastrineus to extract with 3 types of solvents. Each of hexane, ethyl acetate, and methanol, respectively, from low to high polarity. All nine extracts will be extracted. Preliminary examinations for phytochemistry, Antioxidant activity by DPPH radical scavenging assay and quantitative determination of phenolic compounds by Folin-Ciocalteu method and antimicrobial activity were tested. The research found that. 1. The extract of the results of the methanol layer of the S.celastrineus shows a reduction in the amount of 1,1-diphenol-2-picrylhydrazyl (DPPH) had the highest EC50 equal to 31 mg/ml. The amount of phenol compounds found that the extracts from the methanol extract of S. celastrineus contain the amount of phenol. The highest concentration of 95.23 mg GAE / g dw 2. Extract from the bark of the S. celastrineus with methanol showed the best inhibition of the growth of Vibrio paraheamolyticus with the MIC value of 15.60 mg/ml. The extracts of the S. celastrineus leaf extracts with hexane showed the best inhibition of the growth of Vibrio cholerae with the MIC value equal to 31.25 mg/ml and leaf extracts with ethyl acetate showed the best inhibitory effect on the growth of Vibrio cholerae with a MIC value of 31.25 mg/ml and the extract of the fruit with ethyl acetate to inhibit the growth of Vibrio paraheamolyticus most with MIC equal to 15.60 mg/ml.Rajamangala University of Technology Phra Nakho

The Helper and Guide System for Cooperative Education via Web Application

The purpose of this research is to develop a web application for Cooperative Education. The solutions are to help, guides and gives information for a decision before employability in a Cooperative Education project. The system function helps the student to search an establishment by various criteria, such as area, comfort, welfare, and career or open position, etc. In the testing process, the researchers transferred the Cooperative Education training data to the web database. The data recorded was historical data for 6 academic years, since 2010-2016. In addition, the system allows teachers and students to access, comment and rate their satisfaction. Tools used for data storage and user interface web design was Joomla technology. The database was developed with PHP and handle the administration of MySQL by phpMyAdmin. In order to evaluate the effectiveness of web application for the helper and guide system. A survey was conducted on third-year Cooperative Education students with 30 participants. In addition, we invited the specialist who has the experience in the Cooperative Education to evaluate the web application content and performance. The result shows that this system works properly within the defined scope. The satisfaction result was high (4.20). In summary, the system can work effectively.</jats:p

Effect of Ammonium Sulphate ((NH&lt;sub&gt;4&lt;/sub&gt;)&lt;sub&gt;2&lt;/sub&gt; SO&lt;sub&gt;4&lt;/sub&gt;) on Microstructure and Mechanical Properties of SA-213-Gr.T22 and SA-210-Gr.A1 Steel in the Water Tube Boiler

This paper presents the effect of an Ammonium sulphate (NH4)2 SO4) leak mixed in the boiler feed water system on the microstructure, chemistry, metallurgy and mechanical properties of the water tube boiler. Tube specimens were water tube and super-heated tube materials made from ferritic-pearlitic steel alloy grade SA-210-Gr.A1 and ferritic steel grade SA213-Gr.T22, respectively. Specimens were obtained from different height levels of the boiler and tested. The results from the emission spectrometer revealed that the carbon (C) and sulfur (S) did not concentrate inside the tube during five days of operation. Whereas the operating temperature causes the change in the microstructure and mechanical properties due to a segregation of phase and change of mechanical properties (hardness and tensile) in the used tube.</jats:p

Currently, this technology has been widely applied to the education domain and responded to the development of essential skills to survive in the twenty-first century. AR is used to promote self-learning according to the constructivist theory, which believes that learning is a process arising within the learner. Furthermore, the COVID-19 pandemic has conducted to the new way of life, which is called the “new normal”, in which people avoid seeing each other, as well as minimize congestion at all places and contact. Therefore, this research aims to study the transfer of processes and technologies used for development.
