This research is a study of the optimum heat temperature for baking sintered castings for burnout removal of EC 500 type ash wax from cast mortar. Improving jewelry casting process to reduce waste from silver jewelry production process. By studying the temperature of the mortar. To burn remove wax from the mortar and clean the gaps. Then try to bring silver water instead of metal casting. The results of a baked casing study using the EC500 housing prototype from the study showed that the EC500 wax material is melted from all solids to ash wax by heating at 850 ° C to burn. Remove ash wax which makes the cavity clean. When the casting was casted with 925 sterling silver the most complete workpiece after the improvement of the waste jewelry casting process was found to be 1 piece 1 percent 99 pieces or 99 percent.

The research is study motives the affect participation in quality assurance personal of Faculty of Engineering Rajamangala University of Technology Phra Nakhon from example group of 182 people which classified by sex ages position educational degree field of work and working life. This research is used themethod is collecting data by question tool themethod is questionare tool fo collected data that could be two categorized include knowledge skills and attitudes. The questionnaire is five rating scales that analyze the result by frequency percent average the average of standard deviation and T-test independent by using one way ANOVA. The results were as follows : From one hundred percent of the personnel of Faculty of Engineering Rajamangala University of Technology Phra Nakhon whom 63.70 persent classified by the educational field and 36.30% support line are ready to enter into Asean community which could be seen average in whole picture. After considering in three aspects the result appeared that knowledge and skills of personnel are also average. However the attitude of personnel was considered in a high level. Hypothetic test result was found that there was no difference among the personnel with difference sex ages educational degree field of work and working life in their readiness in entering Asean Community. position

This research is to study the recycling of residue clams shell from Mahachai Samutsakorn Thailand. This waste was collected from canned clams industry and it can be recycled as the composition of Mon brick instead of the rice husk. The study of clams shell composition found that Calcium was main composition as 98.50%VS. The moisture and ash content was 0.88% and 58.27%TS respectively. The works methodology is using ash from clams shell incinerated at temperature 900 1000 1100 and 1200oC in 5 hours respectively instead of rice husk in Mon brick processing. The fabrication of Mon brick was in size 5x5x5 cm adding ash from clams shell intead of rice husk. The result found that increasing the temperature to incinerate clams shell ash instead density and compressive strength increased while moisture and water absorption deceased. When Mon brick was fabricated in standard size at 6x15x3.5 cm the changed material characteristics was in the same trend as previous size. Mon brick in standard size adding 100% clams shell ash instead of rice husk had density 2.63 g/cm3 moisture content was 2.86% water absorption at 1 and 24h was 17.40 and 20.16% respectively and compressive strength was 0.52 MPa. These characteristics was according to standard of Engineering Institute of Thailand. It can reduce the cost of rice husk in Mon brick factory 28800 bath/year while the waste from canned clams factory could be reduced 20.94%.

This research is aimed to develop the Electronic Journal Database Management System: Case Study – Academic Journal and Research of Humanities and Social Sciences Rajamangala University of Technology Phra Nakhon. By developing the online database website we will be able to use this to transfer the information review the articles gather information publish the knowledge and innovation from the study research and encourage University’s officers to have the channel to publish their academic journals and Humanities and Social Sciences research. Also this can be used to publish and announce the news via Internet network and use it as a search engine for anyone who is interested in the journals and researches which can be lecturers students or general public. The method for system development started with the system design and get tested by the specialist. After that the system has been experimented with the sample group of Research and Development section officers and researchers and received the report. The system result information has been displayed via website which is developed using PHP MySQL Dreamweaver and Photoshop The results of Electronic Journal Database Management System development : Case Study – Academic Journal and Research of Humanities and Social Sciences Rajamangala University of Technology Phra Nakhon are based on the sample group who are University’s lecturers and officers. The sample group tested the system by searching for the information in the system. The results indicated that the information was filled in from the sample group and displayed correctly.
