Due to the need for Thailand to adapt and develop its economy to keep up with the changes of the world it has to develop technology and innovations with efficiency in order to drive Thailands economy to prosper and keep pace with the rapidly changing global economy. Therefore it is important that educational institutions can help Thailand to have a good economy that is comparable to other countries is to organize the education system with courses that meet the needs of the enterprises. In addition a new generation of entrepreneurs (Start-up) must be created and developed to have knowledge and abilities to drive the countrys economy to be sustainable and efficient. The new generation of entrepreneurs must have knowledge and ability to use technology and innovation in business operations create added value to the economy and bring Thailand into a high income country and people in the country have a better life. Therefore the researcher aims to find guidelines for the development of the Faculty of Science and Technology. Lets step into the development of technology to promote innovation to create a new generation of entrepreneurs with the ability to operate business by using information technology to drive business progress. The samples used to collecte data were personnel students of the Faculty of Science and Technology and establishments related to the occupation of students in both government and private sectors and the research instruments were 2 sets of questionnaires including the 1st set a questionnaire to survey opinions on the development approach of the Faculty of Science and Technology and the second set of questionnaires for enterprises to explore the need for building and develop entrepreneurs in the new era with characteristics that meet the needs of the establishment. The results obtained from the statistical data analysis are guidelines for the development of the Faculty of Science and Technology in creating a proactive strategy to develop the faculty and up-to-date personnel skills training. Access to technology and innovation to step into a university in technology and promote the creation of appropriate innovations to create and develop entrepreneurs effectively.

HV power distribution system circuit breaker are important devices in substations. Such as Malfunction or deterioration of equipment with in the substation will directing impact on the stability of the power distribution system and affect the reliability of the system. In addition this means that it is necessary to assess the actual condition of the proper condition-based operation and maintenance. Thus this thesis presents condition assessment procedure for equipment by using technical information visual inspection by Weighted Scoring Method. Weighting technique is used to determine important weight testing methods of devices by using Analytic Hierarchy Process (AHP). Testing methods for circuit breaker are such as visual inspection contact timing test. Scoring technique is divided into 1-3 levels by classifying on actual evaluate equipment consisting of consisting of good moderate bad. This thesis proposes a software development in order to organize the database and calculate the analysis of the condition of equipment in 5 HV substations. The evaluation results will be divided into 3 levels good medium and bad condition. According to the evaluation level the maintenance types are separated into 1) regular maintenance 2) increase the frequency of maintenance and monitoring of the test 3) equipment must be improved urgently. Finally abnormal incidents of equipment and cost of HV equipment maintenance can be reduced in effective way.

The objectives of the project study were to 1) create the treasure hunting in a real ancient ruin simulation game 2) evaluate suitability of the treasure hunting in a real ancient ruin simulation game and 3) assess satisfaction of game players to the game. The data collected by selective method consisted of 2 sample groups including 3 experts to evaluate suitability of the game who were specialist about 3D VR Game Design and History and 30 game players the treasure hunting in a real ancient ruin simulation game who were ages between of 15-35 years. Statistical data analysis was mean and standard deviation. The results showed that the treasure hunting in a real ancient ruin simulation game overall satisfaction was at a high level (𝒙̅=3.83 S.D.=0.50). Players of the treasure hunting in a real ancient ruin simulation game had overall satisfaction was at a high level (𝒙̅=4.35 S.D.=0.65).

This research had the objective to design and develop power production from daily life leftovers for their highest benefit of utilization by using the principle of quality function development and power generator that changed mechanical energy into electric energy. In developing electric generator product from air conditioner condensing unit the researcher found that there were 4 important factors including speed installation distance size and cross-sectional area of the fan and the test was conducted between 8.00-17.00 hours. The researcher collected the data and analyzed the test result and found that the best result in the test was to install the product at the distance of 10 cm by using an 18 fan in order to acquire the best voltage and the data were collected so that they could be implemented in developing such product in the future.

This research aimed to study the influence of P/E ratio and market capitalization on returns of the securities in the energy sector in the Stock Exchange of Thailand. In this research the researcher has studied and collected data from the closing prices of the securities in energy sector that are currently traded in the Stock Exchange of Thailand. From January 2015 to December 2019 from the Stock Exchange of Thailand 15 companies and used descriptive analysis mean and standard deviation to test the relationship between independent variables by using correlation analysis and multiple regression analysis to determine the influence of P/E ratio and market capitalization on returns of the securities in the energy sector. The results of the research showed that the P/E ratio had a significant positive influence on returns of the energy securities in the Stock Exchange of Thailand. The market capitalization factor also found that it had no influence on returns of the energy securities in the Stock Exchange of Thailand.
