ZnO tetrapods were synthesized by thermal oxidation technique under atmospheric pressure to forming as microstructural scale for increasing a high surface to volume ratio which effects to higher reaction rate. ZnO was mixed in nutrient broth (NB) by varies ZnO concentration from 1000 ppm to 500000 ppm. E. coli was growth in mixed NB under temperature of 37 oC for 24 h. The bacterial growth was investigated by a measurement of optical density (OD) using UV-Visible spectrophotometer at wavelength of 600 nm. It was showed that the OD decreasing as a linear function of ZnO concentration at the concentration in range of 1000 ppm to 50000 ppm. Moreover it was rapidly decreased at the concentration are 100000 ppm and 500000 ppm. The result shows the bacterial growth has been decreased. Therefore we concluded that ZnO tetrapods have an inhibition potential for E. coli.

Indium tin oxide thin films were deposited by DC magnetron sputtering from In2O3 and SnO2 as a ceramic target with 10 wt% of SnO2. The films were sputtered under pressure of 2?10-3 torr power density of 1.23 W/cm2 and substrate temperature of 200 oC. The main goal is to improve the optical properties of ITO thin films by using a mixture of oxygen and argon gasses with O2/Ar ratios varies from 0.0 to 0.5. The best average values of optical properties in the visible light region were found at the O2/Ar ratio of 0.2. The highest transmittance was 90.68% and the lowest reflectance was 9.42%. The result showed reflectance decreased by 5.52% compared to the films sputtered with only Ar.

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 study aimed to 1) the evaluation of the design of Local History WebQuest of Mathayomsuksa 1 students based on constructivism through online social network revealed a high level of quality (= 4.62 S.D.=0.35) 2) the participants who studied Local History by using WebQuest with constructivism through online social network for Mathayonsuksa 1 students showed a better learning progress for no less than 20% 3) the participants’ satisfaction toward studying Local History by using WebQuest of Mathayomsuksa 1 students with the model that has been developed reached a maximum ( = 4.57 S.D. = 0.69).

The study of Reed mat making process and develop the design into a Thai contemporary furniture style. This research is an experimental type and the research designs various functioned furniture. The inspiration come the shape of petal of lotus blossom. The lotus blossom petal’s shape has been one of a characteristic of Thai painting for a longtime. Artists from the old day got this inspiration from nature and the curve and the soft outline of pattern represents the warmth and kindness of Thai people. Therefore the soft outline is the beginning of this design which comes in 3 types. Each type has its own functions but share a lotus blossom petal as an inspiration. First type is the couch second is the arm chair and last is an end table. From a questionnaire about the function of the reed mat the statistic shows the average number on the couch is 4.39 and that is good. The couch is the best choice to be developed into reed mat material furniture due to the strongest structure and heavy load capability. The reed mat already is a mat to lie on; just shaping it into a curve according to Ergonomics theory and it will become a very comfortable couch. This is one way to improve the function in Thai contemporary furniture. Because of the satisfaction average number is at 4.57 which are the highest score; the couch is the best candidate to be applied into more contemporary furniture with Thai art character
