    Electrodeless microwave (MW) discharge in two straight, circular cylindrical resonant cavities in TE1,1,1 and TM0,1,2 modes were introduced to perform additional experimental studies on shock wave modification in non-equilibrium weakly ionized gases and to clarify the physical mechanisms of the shock wave modification process. The discharge was generated in 99.99% Ar at a gas pressure between 20 and 100 Torr and at a discharge power density less than 10.0 Watts/cm3. Power density used for operating the discharge was rather low in the present work, which was determined by evaluating the power loss inside the resonant cavity. It was found that the shock wave deflection signal amplitude was decreased while the shock wave local velocity was increased in the presence of the discharge. However, there was no apparent evidence of the multiple shock structure or the widening of the shock wave deflection signal, as observed in the d.c. glow discharge [3,5]. The shock wave always retained a more compact structure even in the case of strong dispersion in both the TE and the TM mode. The shock wave propagated faster through the discharge in the TE mode than in the TM mode. Discharge characteristics and local parameters such as gas temperature Tg, electron density Ne, local electric field E, and average power density, were determined by using the MW discharge generated from an Argon gas mixture that contains 95% Ar, 5% H2, and traces of N2. The gas temperature was evaluated by using the amplitude reduction technique and the emission spectroscopy of Nitrogen. The gas temperature distribution was flat in the central region of the cavity. By comparing the gas temperature calculated from the shock wave local velocity and from the amplitude reduction technique, the present work was sufficiently accurate to indicate that the thermal effect is dominant. The electron density was obtained from measured line shapes of hydrogen Balmer lines by using the gas temperature and the well-tested approximate formula for deconvolution of Stark and Doppler broadening. The local electric field inside the MW discharge was evaluated by using a simplified kinetic model. Dispersion of a shock wave in a MW discharge will most likely be applied in future technical solutions in aircraft design, or rocket shock wave modification systems. We hope that the present study will contribute to a better understanding of the physical mechanism leading to shock wave dispersion in weakly ionized gas

    To investigate of pupils were observed and interviews of their early childhood classroom learning environments with the instructional internships in teaching early childhood of the pre-primary activity trainee student teacher internships for improving and creating scientific attitude skills toward early childhood in pre-primary educational school level in Thailand. Associations between these perceptions with their performances and pupils' attitudes toward early childhood performances were determined. Using the research instruments on classroom learning environments obtained of the 25-item My Class Inventory (MCI) and with the 8-item Test Of Performance-Related Attitude (TOPRA) were assessed which convention on individualized open and inquiry-based education, teacher-pupil interactions, and pupils’ creating activity performances attitude skills were assessed with the volunteer staff with the observe and interview forms. The MCI questionnaire has an Actual Forms and a Preferred Form. The questionnaire was administered in three phases with the Custer Random Sampling technique to a sample consisted of 720 pupils in 30 early childhood classes from 30 schools at the pre-primary levels in Maha Sarakham Primary Educational Service Area Office 1-3 and Roi-Et Pre-Primary Educational Service Area Office 1-3. Statistically significant differences between pupils were observed and interviews of actual-1, actual-2 and preferred performance activity learning environments of their classroom climates, distinguish individualized classrooms with their improving and creating attitudes skills’ sustainable development were also found. Predictions of the monitoring and evaluation of managing activity performances by the trainee student teachers of their internships; pupils’ skills developments of their activity performances’ sustainable for the set of actual and preferred environments as a whole and early childhood related attitudes also were correlated. The R2 values indicate that 57%, 72%, and 80% of the variances in pupils’ attitudes to their actuale-1, actual-2 and preferred for the MCI in early childhood classes were attributable to their performances of their actual-1, actual-2 and preferred environments and their developing creative activity performances skills’ sustainable toward activity performance are provided

    Inclusive education is a central step of education management in the new millennium: it, allow every child to learn, which is a human right. Education management for the children who have special needs is based on a belief that every of them has capability and potential to learn and develop if appropriate learning opportunities are granted. This study aims to answer the following research questions: 1) What are the current status of, problems of, and needs for inclusive education in Thailand ? 2) What are the inclusive best practices in other countries ? 3) How can this body of knowledge be applied to Thailand’s inclusive schools ? The researcher is therefore interested in investigating and developing the inclusive education model for the entire school system. This is accomplished by conducting research and applying development design, using mixed methods and both quantitative and qualitative approaches (John W.2007). The results of this study will yield the following expected benefits of: 1) Acquired knowledge on the current need for inclusive education in mainstreaming schools, The problems will be clearly identified, leading to a plan for the development of an effective inclusive education model relevant to the actual situation in schools. 2) A body of knowledge from the inclusive best practices in other countries, applicable to Thailand’s core mainstreaming schools; and 3) An inclusive education model that will benefit children with special needs, teachers, school administrators, parents, communities, and special needs education management organizations in Thailand.

    The sampling groups in this research are customer who use the banking service via Internet system and the customer of D-Computer Co., Ltd. who usually use Internet Banking services such as inquiry about outstanding balance, fund transfer between accounts, and transfer payment for public utility. The sampling group specification of this research are must use Internet Banking services at least once a month. The research tools are questionnaires in the Web page form. Questionnaires are adapted from the tools that are used to evaluate the service quality called “The dimension of quality by David A. Garvin” by evaluating the quality of eight dimensional services: Performance, Features, Reliability, Conformance, Durability, Aesthetics, Serviceability and Perceived quality. During the sampling survey, we received 300 questionnaires that being answered completely. For information analysis, we use the fundamental statistics to analyze the characteristics of sampling group and test the relative variable factor by means of Chi-square and obtain the result to build a variance factor linear prototype. The results were as follows: 1. The quality level of internet banking service of commercial banks in Thailand in the perspective of performance was different in each bank. 2. By weighting the important of criteria that used to evaluate the Internet Banking service quality in Thailand, the most important was the dimension of reliability, serviceability and durability. The less important was in dimension of perceived quality
