The objective of this research was to study environment changes in orchards by using wireless sensor network and spatial data interpolation technique. The study was conducted by distributing several client sensors into the two study areas for recoding temperature himudity and light internsity. These data are send to a server using 433 MHz radio signal. The results from the first study area in Thachang District shew that the light intensities were significantly changed during 6:00-6:59 11:00-14:00 and 18:00-19:59. For the humidities they were significantly changed during 7:00-8:59 17:00-19:59 and 22:00-23:00 which were quite different from the changing of light intensity. Lastly the temperatures were mostly changed during 7:00-7:59 10:00-14:59 and 18:00-19:59 which were highly related to the changes of light intensity. For the second study area in Angkhiri District light intensities were significantly changed during 7:00-7:59 11:00-14:00 and 18:00-19:59 while the changing durations for the humidities were 9:00-9:59 12:00-15:00 and 17:00-19:59. Very similarly to the light intensity the temperatures were changed during 8:00-8:59 11:00-14:59 and 15:00-17:59. For the communiation distances the maximum distance for transfering data in an open area was 100 meter and 25 meters with obstables.

The purposes of this research were to study and explore the relationship between the attitudes toward the preservation of banana-leaf crafts flower works and decoration of fresh flowers of the Faculty of Home Economics Technology students Rajamangala University of Technology and individuals as well as internal and external factors. Research samples were 270 undergraduate students of the Faculty of Home Economics Technology from Rajamangala University of Technology Phra Nakhon Rajamangala University of Technology Krung Thep and Rajamangala University of Technology Thanyaburi. The samples were selected by using stratified sampling. The research methods were questionnaires and testing forms. Data analysis was performed by descriptive statistics and inferential statistics. The results of the study revealed that the attitudes toward the preservation of banana-leaf crafts flower works and decoration of fresh flowers of the Faculty of Home Economics Technology students Rajamangala Univers

This paper is a presentation of the Load-Frequency Control (LFC) of Interconnected Power System by using Fuzzy Logic and Artificial Neural Network (ANN) Controller. The both of controller have been widely applied for handling the system control of Industries and Engineering. Since the Load-Frequency behaviors of power system of uncontrolled and PI- Controller or Fuzzy Logic Controller (FLC) wanted to the stability at first of energize and load in a short time. The control system and controller then be significant for to go forward reform stability of interconnected energize power system a short time. In this research we have the Load-Frequency Controller of Interconnected Power System by using Artificial Neural Network Controller the improved can compared with conventional Fuzzy Logic Controller at power total 47.55 MW and load changing of power plan No.3 is 0.02 p.u. (1.75 MW)

The purposes of this research were to examine quality of work life and work performance of teachers in Rajamangala Technology University of technology isan and to compare the quality of work life and work performance of teachers in Rajamangala Technology University of technology isan. Sample for the study consisted of 165 teachers in university. Data were obtained through the use of questionnaires and analyzed using descriptive statistics t-test ANOVA and sheffe. The 0.05 level of significance was chosen for the analysis. Results of this study revealed that all of the aspects of the quality of work life of teachers in were at the moderate level and work performances of teachers were at the high levels. Regarding the comparison of work life quality and work performance of teachers in Rajamangala Technology University of technology isan When classified by highest of Education there was found to be no significant difference at 0.05. The analysis of variance to compare the quality of work life regarding to teachers’ different job experience teacher’s different salary as a whole or individual revealed no significant differences.

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
