This research aimed to : 1) study the constructivist teaching method through cooperative learning activities to enable students’ self-instruction 2) to design the cooperative teaching and learning model based on the constructivism for the information literacy and research skills course for the students at Rajamangala University of Technology Phra Nakhon and 3) to develop the constructivist-cooperative teaching and learning instruction to develop critical thinking and learning achievement for the information literacy and research skills course at Rajamangala University of Technology Phra Nakhon. This research used a mixed-method between quantitative research and qualitative research. The data were collected from 30 students using the questionnaire approved by the experts. The in-depth interviewed data from five students who were fast acute and adept learners were analyzed and processed. The computerized statistics were percentage mean and standard deviation. The qualitative data were analyzed for content (Content Analysis). The findings showed that the students had the opinion at a high level about the model of constructivist-cooperative teaching and learning model in the information literacy skills course. Regarding each aspect it was found that the students were extremely satisfied with the constructivist-cooperative teaching and learning model. The following satisfaction lied in the development of the teaching and learning model and the trial of the model conducted with real students to see any potential flaws for further improvement and development of appropriate and effective instruction models. In addition the opinions of the informants were accordant with those of the students. The model should focus on the content and the instruction design. Group works should be used so that students can help each other. Experts in constructivism should play a main role in the development of a constructivist-cooperative instruction model. The constructivist-cooperative instruction model should be implemented with real students. The results can be further used for improvement and development of appropriate and effective instruction models.

In this work fiber mat based on silk sericin and thunbergia laurifolia linn extract was developed via electrospinning technique for wound dressing application. The waste cocoons were selected from Nakhon Ratchasima 1 (K1) with appropriate spicy for extracting the silk sericin protein. Trunk of thunbergia laurifolia linn was selected for preparing thunbergia laurifolia linn extract. Polyvinyl alcohol (PVA) with several concentrations were chose and fabricated to fibers by electrospinning technique to investigate suitable polymer concentration for mixing silk sericin and thunbergia laurifolia linn extract. The result revealed that PVA of 9 wt % was suitable due to Several parameters were investigated to prepare the electrospun fiber of silk sericin and thunbergia laurifolia linn extract such as their mixing ratio voltage the distance between the needle and the substrate and the needle size. The results indicated that mixing ratio of silk sericin and thunbergia laurifolia linn extract at 50:50 (w/w) voltage of 15 kV the distance of the needle and the substrate at 8 cm and the needle size of 18 were optimum condition for the fabrication of electrospun fiber with diameter of 100-200 nm and that with smooth and continue feature.

This research is the study and development of the information system for managing resources and database by focusing on the workload academic teacher (WAT) systems for the teachers worked on the Faculty of Science and Technology Rajamangala University of Technology Phra Nakhon. The main objective was to develop the WAT systems based on the web-based application (web application) and to evaluate the effectiveness and to assess user satisfaction with WAT systems. The WAT systems were also performed based on the system development life cycle (SDLC) and requirements gathering analysis of existing systems with the paper-based managements to new systems for use in the electronic managements. The evaluation of efficiency of the WAT systems was performed by the information technologists for the functionality of WAT systems resulting in the average satisfaction score is 4.36 with the standard deviation of 0.54. As the same experts the satisfaction of usability such as login procedure choosing the workload issues to easy document upload and filledforms performances etc. resulting in the average satisfaction score is 4.29 with the standard deviation of 0.55. These results provided the high level of experts’ satisfaction. After improving the WAT systems the functionality and the usability of systems were evaluated by usage teachers. It was found that the average satisfaction score of the functionality is 4.21 with the standard deviation of 0.67 and the usability is 3.56 with the standard deviation of 0.96 (n=15). It can be implied that the WAT systems can be applied to practical and responsive to the needs of users.

The research project investigated the effects of CoO additive on dielectric ferroelectric physical and mechanical properties of modified Bi0.5(Na0.81K0.19)0.5TiO3 ceramics were investigated. The samples were synthesized by solid state reaction technique where powders were calcined at 850 °C for 4 h and ceramics were sintered at 1050 °C for 4 h which difference heating rate controlled i.e. 100 300 and 600 °C/h for. The ceramics of BNKT/x wt.% CoO was added CoO by various x=0.00 0.10 0.20 0.30 0.60 and 0.90. Phase formation was determined by X-ray diffraction technique (XRD). The X-ray diffraction analysis of the ceramics suggests that all samples exhibited a perovskite structure. The dielectric properties under room temperature and various temperatures were also determined. Dielectric measurement data showed that the additive and heating rate controlled influenced dielectric constant and dielectric loss. Furthermore the hysteresis loop behaviors slightly changed with increasing the CoO contents.

The purposes of this research were to development of full-text research database for Rajamangala University of Technology Phra Nakhon and valuate the efficiency of the database system of full-text research database for Rajamangala University of Technology Phra Nakhon. The sample was academic staffs of RMUTP 35 academic staffs. Research design was a research and development follow these steps : study and analyze problems system design development system trial and evaluation of user satisfaction. For the study satisfaction using the evaluation form. The statistics used for data analysis were mean (𝑥̅) and standard deviation (S.D) The results demonstrated that : 1. Development of Full-Text Research Database for Rajamangala University of Technology Phra Nakhon by using database management software MySQL (MySQL) and PHP (PHP). The database developed has the ability to save edit delete and query. 2. Database System of Full-Text Research Database for Rajamangala University of Technology Phra Nakhon performance was good and the mean was 4.22 and the standard deviation was 0.19.
