The purposes of this study were 1) to create a construction of design program for practical skills system of engine repairing 2) to determine the quality of design program for practical skills system of engine repairing 3) to evaluate the users’ satisfaction of a design program for practical skills system of engine repairing. The sample used in this study consisted of 30 lecturers from automotive division university and 39 lecturers from the office of vocational education commission. The tools used in this study were the quality assessment for practical skills system of engine repairing and the satisfaction assessment of the users to design program for practical skills system of engine repairing. The statistics used for data analysis were percentage mean standard deviation and t-test for dependent samples. The results of the study were as follows: 1) the quality of were very good level design program of for practical skills system of engine repairing( = 4.70 S.D. = 0.21). 2) User’s satisfaction level after accessing the program were very good level ( = 4.60 S.D. = 0.11). 3) The results were compared to assess the satisfaction level of the user from Nakhonphanom university and the office of vocational education commission towards of design program for practical skills system of engine repairing in the field of design content and application found that in each of the satisfaction level did not differ significantly at .05 level. 4) The results were compared to assess the satisfaction level of industrial community education and technical college towards of design program for practical skills system of engine repairing in the field of design content and the application found that in each of the satisfaction level did not difference at significance level .05

The objectives of this research are 1) to study usage behavior and satisfaction in the information technology of personnel in the Ministry of Culture. 2) To study the relationship of usage behavior and satisfaction of personnel in the Ministry of Culture towards the information technology. 3) To compare behavior of personnel in the Ministry of Culture in using information technology which different in demographic characteristics. 4) To compare the satisfaction towards information technology of personnel in the Ministry of Culture which different in demographic characteristics. The representative sample of this research is 250 personnel in the Ministry of Culture. In addition for this research questionnaire has been used as a statistical methodology. The result of this research implies that most of the personnel in the Ministry of Culture are female 74.4 % of them use and exposure into the information technology by using desktop computer and most of these people are greatly satisfied in the information technology. Moreover regarding the effective and fast intercommunication it has been found from the statistical hypothesis testing that the demographic characteristics differences such as gender age marital status education and average income per month have the differences in the usage behavior and satisfaction of the information technology and the usage behavior of the information technology has a relationship with satisfaction in using information technology of personnel in the Ministry of Culture.

This research is the study for effected of orientation setup workpiece from Rapid Prototyping process. The objective of this study has to minimize average tolerances of specimen size and roundness of cylindrical specimen. Specimens were studied with orientation direction define 3 axis (X Y Z) and created by rapid prototyping Machine with FDM Technology. The Measuring average tolerance of specimen size and roundness of cylindrical specimen used the Coordinate Measuring Machine (CMM). The Result showed that test specimens were formed along the X axis having lowest of average tolerances. The increasing average tolerances of diameter depend on the increasing diameter size. The roundness value of cylindrical surface forming the X axis was the most circular cylinder. The roundness value of cylindrical was depend on the increasing of diameter size. It shows that when the workpiece has a larger diameter. The workpiece would be circular cylinder is decrease

This research aims to construct and evaluate efficiency of experiment set for work-piece analysis based on variety of cutting edge parameters of punch-die. The parameters included clearance punch shape and inclination of punch edge that related to cutting force error in diameter and deformation of work-piece. The developed experimental set was evaluated by 15 experts using 5-point scale questionnaire which was divided into two parts: content and worksheet and experiment set design. The efficiency evaluation was done by using the experiment set to teach a sample group of 15 students. Results showed that quality of the proposed experiment set was in the highest level with average score of 4.65 (SD = 0.47). The efficiency evaluation by teaching a sample student group revealed that the efficiency was 85.43/84.00 which was higher than the criteria of 80/80 in research hypothesis. Therefore it can be concluded that the constructed experiment set could be used to enhance students’ analytical thinking in punch-die work.

This research is aimed to study both the species diversity and utilization of plants at the Baan Tah Tongdeang community forest Nabot Wangchao districtTak province. The survey of plant species and the available quantity has been carried out using the quadrat method. The leaders and intellectuals in the community were interviewed using a structured questionnaire. The result showed that the plant with the highest Density (D) and Relative Density (RD) were Tectona grandis L.f. (0.734375/m2 7.742998353) Xylia xylocarpa Taub. var. kerrii Nielsen (0.6875/m2 7.248764415) Grewia eriocarpa (0.65625/m2 6.919275124) respectively. Whilst plant with the highest Frequency (F) and Relative Frequency (RF) were Xylia xylocarpa Taub. var. kerrii Nielsen Grewia eriocarpa and Holoptelea integrifolia Planch. (87.5 4.96) Tectona grandis L.f. and Schleichera oleosa (Lour.) Oken (75 4.26) Pterocarpus macrocarpus Kurz and Bombax anceps Pierre (62.5 3.55) respectively. The Shannon and Wiener’s diversity index (H’) of trees was 3.38 while evenness index was 0.85. The utilization of the plants in the community included 94 species as wood (used as plank furniture firewood charcoal string chemical extraction etc. 62 species as medicinal herbs 47 species as wild vegetables fruits and foods. All of them are utilized in the community. The results of this research would be beneficial for administrative and management as a guideline to preparation a community biological database and learning resources for conservation and sustainable uses of natural resources and environments in Baan Tah Tongdeang community forest.
