This project were study to Nakhon Si Thammarat embossed pattern to conserve the usage of endure Thai fabric with Jacquard. The purpose of this project were to develop Nakhon Si Thammarat embossed pattern by computer program and to be woven with Jacquard ( JACQUARD) . The extent were the pattern from a woven traditional fabric with loom from Ban Noen Thammang Arts & Crafts Center at Ban Noen Thammang Mae Chao Yuhau Sub district Chian Yai District Nakhon Si Thammarat Province. This project was the qualitative. It used blend method to achieve the objective the study of traditional pattern process and the pattern was designed by a computer program (STITCH) to be able to applied to the Jacquard in order to preserve and promote the innovative usage Thai pattern design that enhanced the ability to weave faster more convenient and using only one weaver that faster than weaving with loom that had many instruction many persons and a lot of time when wove it. This would yield less. Weaving with Jacquard (JACQUARD) was woven to be more productive to be market more to reach more consumers which was conserved to be sustainable for Thai fabric. The result of study Nakhon Si Thammarat embossed pattern and Jacquard process (JACQUARD) to study Mimusops pattern 2 layers cone shaped and brought the design to come down the computer ( STITCH) by studying the patterns and characteristics of the Nakhon Si Thammarat embossed pattern to out graphs and tables were used to make cards. Then brought it to use with Jacquard. It could reduce problems in various areas that were 1. Reduced manual labour in raising heddle that took 3 people held it including weaver while Jacquard (JACQUARD) rose by heddle only one weaver. 2. Reduced time to decrease. 3. Reduce the weaving process with Jacquard ( JACQUARD) . It could be woven continuously and woven patterns could change quickly without raising the heddle or collecting again. The patterns could still preserve the original design to create the Nakhon Si Thammarat embossed pattern were beautifuleye-catching and outstanding including the Nakhon Si Thammarat embossed pattern design by computer program (STITCH) to 120 heddles and could design complex easier. All things that mentioned to help the weavers to more earn income. Consumers increasingly recognized that were the dissemination of Nakhon Si Thammarat embossed pattern to have more use and considered a sustainable conservation of this fabric.

A disc brake is one of important auto parts for motorbike cycle industry which effected directly to life safety. As the result this project aims to test the performance of the disc brake in order to study the physical disc brake that effects to braking distance and to be an alternative for testing the brake disc. The braking performance tester was designed and created in the single dynamometer which was not over 10 Hp and the 17of inertia .70 kg. m. Referring to testing state of JASO T204:2001 standard this tester focused on testing the 3 different types of disc brake i.e. normal type grooving type and perforated type. The tested temperature was at normal state of the brake disc temperature (60° C - 80° C) and at high state (more than 100° C). The braking force from 9.81 N to 34.33 N at master cylinder was tested. moments was not over 92 The result revealed that at normal temperature the braking performance of the three disc brakes (normal type grooving type and perforated type) was at 17.76 21.80 and 19.00 per 1 mrespectively. However the brake performance at high temperature was at 14.41 18.06 and 18.93 per 1 m. This meant that the most efficient disc brake at normal temperature was grooving type of disc brake which was 22.74% different from normal type of disc brake. Nevertheless; the perforated type of disc brake was the most performance disc brake at high temperature which was different from normal type of disc brake at 25.32% 2 of contact surface areas 2 of contact surface areas respectively2m/s2m/s

The objectives of this research are to develop the welding process of copper tube for refrigeration in air conditioner by using rotation brazing table. The key design is the use of rotary head for nitrogen and rotary head for cooling water in assembly jig nitrogen discharge to prevent the internal welding soot to remove the soot that may occur during welding from piping system and to cool down the profile quickly. The result of water cooling to prevent that damage due to the heat of welding. The result from designing and creating of rotation brazing table to substitute stationary welding found that there is the reduction of machine cost by 11.61% or 46000 Baht/machine reduction of usage space 8.75 square meters or 74375 Baht increase of productivity by 93.48% reduction of nitrogen consumption by 98.20% or 2593 Baht/month reduction of support tool in production 75000 Baht per one rotation brazing table reduction of tiredness from working by 30.24% or equal to 137 manual works per day and reduction of usage of consumable material that can cause of greenhouse gas in form of trash such as cloth glove 1.40 KgCo2 per year leather glove 12.5216 KgCo2 per year nitrogen gas 0.1784 TonCo2 per year and water 0.54 KgCo2 per year. All of these can support the competition and dynamic change of industrial air conditioner in the future sustainably.

The purpose of this reserch was study status problems and needs in media utilization of instructors of Rajamangala Institute Technology Chotwet Campus. Reserch gathers information from population 47 instructors. Quastionnaires were reserch tools. Percentage mean and standard deviation were used for data analysis. The result revesled that There was moderate in media utilization Tesching method and instruction were used moderately such as description discussion and demonstration highly used fechnique was experiment. Tools and equipments were used wodeklately such as loud-spesker overhead transparency projector were used highly. Instructional medias were used moderately highly used matenak were transparencies. transparent pens boards and resl meterials. The problem in media utilization was moderately perparation and buying had a moderste problem. High problem was lack of comveniency to produce educational media such as personel officers tools materials equipments buildings places and lack of budget in order to buy educational media. Chosen and use in educational media had a little bit problem but there weremoderately level in time consuming to prepare themselves and complicated to move. Quality and quantity of educational media had a moderste problem such as places rwewnt suitable with media utilization couldnt control the light of projectors amount of educational medias weremt sufficient with needs. SeNice had a moderate problem highly problem were lack of personnel to make photoes slides cassette videotape and lack of personnel to produce graphic chart and portary works for teaching compose not enough. The need of media utilization was highly in tools and equipments. Moderately needs were overhead transparency projectors and transpatent pens. The following needs were opaque projectors and projectors videotapes. Service had highly needs such as buying high quality educational media as a teaching compose The following was preparatory necessary educational media such as overhead transparency projectors loud-speskers and microphones permanency in all of class rooms.
