The purpose of this study was to study the history of a cultural architecture resources and environment in the local community. The history that found was used to be information to find the development of potentiality of cultural tourism to carry on the cultural activity which related to the local community to encourage local people to beneficially manage the resources and to accommodate the tourism in Nan local government. All of these operations were focused on the cooperation of monks and local people by debating. This study collected data by using random survey questionnaire of local people tourists and tour guides. Moreover the interview of local instructors local people and other people was also used in this study. The development of the potentiality of cultural tourism at Wat Satharot still need help from government by adding a streetcar park at Wat Satharot and promoting a tourist attractions in variety of advertisement. The local people combine in to community to manage the tourism. For tour guides and tourists they need some souvenir shop and antique and beautiful sightseeing.

The shrinkage depended on the product shape and the type of plastic used in injection melting temperature injection speed holding pressure and mold cooling. Different surroundings during the injection resulted in differences shrinkage so the exact shrinkage value hadn’t been known. This was the cause of Try out and error work that produced Injection products that were not in correct size. This research aims to find the shrinkage percentage based on the ASTM D955 standard test method from high density polyethylene (HDPE) which has partial crystalline structure and high shrinkage. The results were as follows: The specimen size 60x60 mm shrinkage was at 2.57 percentage and with 2 mm thickness the shrinkage was 3.60 percentage. The specimen size 12.7x127 mm shrinkage was between 2.76 percentage and 2.91 percentage with 3.20 mm thickness the shrinkage was 2.48 percentage. For the 100 mm circular specimen the shrinkage was from 4.35 to 4.39 percentage and with 3.20 mm thickness the shrinkage was 2.56 percentage

The design of plastic injection mold requires precision and efficiency of the injection. Therefore mold design engineers need to determine the size location and number of the gates to fit the length of the plastic flow in the work piece so that when the injection mold is built they’ll get the complete and specified specimen. This research was conducted to study the influence of injection flow channel thickness affects the flow index. Poly ethylene high density High density polyethylene HDPE was used in the experiments. The flow of plastic was Spiral Test according to ASTM: D 3123-94 with rectangular cross-sectional area of 6 mm. wide 6 mm. pitch. It was found that the thickness of the flow channel at 0.51.01.5 and 2.0 mm. which has the best flow rates at the best injection speed at 25% the injection pressure at 30% and the flow distance of 52 116 238 and 299 mm respectively with the plastic melting temperature between 190 C and 220 C.

The purposes of the study were to study the need competency and to develop the competency in information and communications technologies of teachers. The samples were 363 teachers of Rajamangala University of Technology Isan and 70 trainees of experimental group. There were 4 stages of methodology: 1) Study the basic information in order to analyze the need 2) Study the competency of ICT to analyze 3 parts of competency which were knowledge skills and features needed 3) Development preparation and 4) Training course development. The Tools were the questionnaire the achievement assessments of pre and post trainings and the evaluation of the training. The results revealed as follows: The need in information and communication technologies of teachers in 9 aspects was at the high level. The teachers training achievement is significantly different at the level of 0.05. After training the achievement is higher than before regarding the training course expectation teachers are satisfied with this workshop training at the high level. For the suggestion it should be follow-up continuously after training.

This research aimed to transfer technology about biogas digester construction and applying the biogas in household to teachers and students in Suksasongkhro Tak school. They were instructed and trained about biogas digester construction and applying the biogas produced from animal manure on cooking in household to reduce using LPG. The research operations were separated to 4 phases. The first was preparation and making understanding. The second was instruction and practical training. The third was monitoring and project evaluation. The last one was organizing the science project event. The number of participant teachers and students was 330. From the result of 5 scale questionnaire in project evaluation it was found that the evaluation about knowledge and understanding showed the maximum scale ( = 4.42 SD = 0.84). The second was about location duration and food ( = 4.36 SD = 0.75). The evaluation about the knowledge showed the lowest scale ( = 4.28 SD = 0.77). For the project evaluation of success it was found that every biogas digester done by participants could produce the biogas and it could be use to replace LPG and reduce expenditure about 1400 – 1500 baht/month. The total construction cost of biogas production system was 58000 baht. So the payback period was 3.22 years.
