The study entitled “An Analysis of Local Wisdom on Herbs from Anti Sara Wak Scripture” is a mixed-method research. The research objectives were to evaluate the value of Anti Sara Wak scripture and to analyze beliefs in Thai society which occurred in this scripture. The samples of the study obtained from a convenient sampling were five experts of Nang Leong community. The research instrument used for data collection was questionnaire consisting of 4 parts: part 1 respondents’ general information part 2 and 3 relevant to the experience in using herbal medicine and the faith in Admiral Prince Abhakara Kiartivongse Prince of Chumphon or the author of Anti Sara Wak scripture and part 4 the open-ended section asking suggestions to further investigate Anti Sara Wak and beliefs in Thai society which appeared in this scripture. In addition the depth interview was also used to collect the data from 5 experts of Nang Leong community. The data were then analyzed to find out the value of Anti Sara Wak and beliefs in Thai society from the scripture. The majority of the respondents were elderly people. The oldest respondent was 79 years old. These respondents rated the questionnaire: 5 for strongly agree 4 for agree 3 for neutral 2 for disagree and 1 for strongly disagree reporting their attitudes towards the use of Thai herbal medicine. The results of the study show that the respondents strongly agreed with the use of Thai herbal medicine in daily life (80%) because it was suitable responding to the objective. They also added that Anti Sara Wak scripture should be publicized (90%). However there was little information available on Thai herbal medicine (30%). Additionally the results showed a strong faith in Admiral Prince Abhakara Kiartivongse Prince of Chumphon (90%). The results of analyses show that there were beliefs in Thai society that appeared in Anti Sara Wak scripture especially folklore beliefs such as superstitious beliefs holy things as well as tips and forbidden rules. Therefore Anti Sara Wak scripture provided empirical evidence in Thai history showing its value as one of Thai traditional medicine recipes.

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 objective of this research is to propose a new way to fabricate a composite material for future bone replacement development via growing apatite crystal on silk fibroin fiber. Apatite crystallization on silk fibroin fiber was prepared by precipitation reaction between Ca(NO3)2 solution and (NH4)2HPO4 solution adjusted pH by NH4OH solution. In this work Effect of solution concentration and initial pH values was investigated on apatite crystals. Chicken eggshells were used as calcium source by heating sufficiently powdered eggshells at 1300 °C for 4 h to acquire CaO powders made Ca(NO3)2 solution by dissolving in 65% HNO3 solution. Prepared Ca(NO3)2 solutions were adjusted concentration as 3 levels and were adjusted different pH values of 7 8 and 9 respectively. For processing of apatite crystallization silk fibroin fibers were immersed in Ca(NO3)2 solutions for 30 min. After that (NH4)2HPO4 solutions were added in silk fibroin fibers immersed in Ca(NO3)2 solutions. Reaction time was fixed about 1 min before cleaning to remove impurity precipitates on surface of silk fibroin fiber. Finally apatite crystallization on silk fibroin fibers occurred. The obtained result can conclude morphologies of apatite crystals on silk fibroin fibers was sheets sphere and flower. Solution concentrations and initial pH values directly influenced on Ca/P ratio of obtained apatite crystals by Ca/P ratio increases as increased solution concentrations or increased pH values. Finally research silk fibroin fibers were woven as two patterns of plain weave and twill weave and they were investigated Young’s modulus and tensile strength. The result indicates that Young’s modulus of silk fibroin fiber sheets woven as twill weave and as plain weave were about 616 MPa and 425 Mpa and tensile strengths of them weave were about 40 Mpa and 72 Mpa respectively. The optimum condition of growing apatite crystals on silk fibroin fibers was sample of CP19. Design of silk fibroin fiber with plain weave was an optimum pattern for future biomedical applicaions.
