This research aimed 1) to study levels of transformational leadership innovative climate knowledge management systems innovative work behaviors and firm performances 2) to investigate causal relationship of transformational leadership innovative climate knowledge management system as well as innovative work behaviors which influenced on performances of the Medical Device Business in Thailand 3) to examine relevance of those variables along with causal relationships of the antecedents affecting performance of the Medical Device Business in Thailand to empirical data. Data were collected from 312 middle level managers in Medical Device Business in Thailand by using questionnaires as a research instrument. All of the data were analyzed using Structural Equation Model. The analysis of correlation coefficient model showed that the latent variables significantly related to one other at statistical level of 0.001. The analysis of structural equation model (SEM) revealed that the model was completely compatible with the empirical data and the hypothesis. (GFI = 0.933 CFI = 0.972 RMSEA = 0.078 RMR = 0.018) The findings also showed that transformational leadership significantly affected innovative work behaviors at statistical level of 0.001. Similarly innovative climate significantly affected innovative work behaviors at statistical level of 0.001. Likewise knowledge management system significantly affected innovative work behaviors at statistical level of 0.001. Finally innovative work behaviors significantly and directly affected the firm performance at statistical level of 0.05.

This research presents the development of ultrasonic scaler for mobile dental unit. The operation of the scaler uses a phase-locked loop circuit to generate high frequency electrical signal. Then the signal is amplified with a Darlington amplifier circuit to feed to the coil in the Hand Piece resulting in Magnetostriction. This phenomenon causes the stretching and shrinking of the magneto-strictive stack with high frequency which causes the tip of the scaling head to vibrate more than 20000 times/second. Traditional ultrasonic scaler for mobile dental unit has thermal problem of the amplifier circuit due to use of the transistors as the switching devices. When used for a period of time the scaler is necessary to stop working resulting in not much scaling per day. This research solved the problem by using MOSFETs as switching devices and adding cooling system to the amplifier circuit. The experiment was carried out using actual conditions. The experimental results show that the developed scaler has increased the number of scaling per day. In addition it will still remove plaque and dirt in the gumline around the base of the teeth similar to the scaler used by general dentists.

The purpose of the research was to test the effects of learning orientation and knowledge management capability on innovation excellence and export performance of furniture exporting business in Thailand. The questionnaire was used as a research instrument to collect the data from 185 managing directors of business of furniture exporting business in Thailand. The statistics used for analyzing data were multiple correlation analysis and multiple regression analysis. The results of the research showed that learning orientation had a positive significant an effect on knowledge management capability but it does not a positive and effect on innovation excellence and export performance. In addition knowledge management capability had a positive significant an effect on innovation excellence but it does not a positive significant an effect on export performance. Also innovation excellence had a positive significant an effect on export performance.

One of major missions of Rajamangala University of Technology Phra Nakorn is to promote studentscreation of research invention and innovation in order to add values to production sector and national academic service. The Promotion of Inventions and Innovations by Young Generation Project has been since 2008 initiated to provide necessary support development of undergraduate students works. The project aims to promote and improve students invention and innovation as well as to encourage national publication. This project has enhanced students professional expertise which would develop into Hands-on graduates. Results of the project were presented at national level and severaltools devices and products had been produced and evidently utilized to improve production process of communities and industrial sector. The 1st Rajamangala University of Technology Phra Nakhon Innovation and Technology Exhibition is another activity that has presented results of the project to public. The activities included an exhibition of students innovations ana technology a forum on Hands-on graduate development and a contest of students works. This initiation clearly corresponds with the mission to promote students creation of innovation in oder to produce hands-on graduates who have curiosity persistence technological expertise and morality in accordance with the university identity.

To store electrical power from solar cells are generally used battery as storage. Recent development in capacitor technology achieves with higher capacitancc smaller and low cost especially dcvelopment of a supcr capacitor (doublc laycrs). This research study used a super capacitor to store electrical power from solar cells. The results show that super and electrolyte capacitor can be used without battery with more power density and fast charge. But capacitor discharging must be controlled. The important disadvantage is super capacitor is used with low voltage and high rate of charge leakage. In case of electrolytic capacitor can use with higher voltage low rate of charge leakage but lower capacitance.
