The study on factors affecting the performance of Thai Tridymite Limited employees was aimed to investigate their personal factors incentive factors teamwork behavior work performance motivation affecting the work efficiency and behavior factors that affected the employees’ performance. The population used in this study was 113 employees. The data analysis relied on the statistics including percentage average and standard deviation. The hypothesis testing applied multiple regression analysis (Multiple Regression Analysis) at the 0.05 significance level. The results showed that the employees working at Thai Tridymite Limited were mostly female between the ages of 30-40 years old with a bachelors degree earning 10000 - 20000 Baht income in the average. They had been working for the company for lower than five years and had high-level motivation concerning job responsibility work success work progress acceptability salary income management interpersonal relationship administration policy work conditions and work security. As a whole the level teamwork behavioral factors was high including the team mission and goals work assignments according to the delegation of duties open communication distributed leadership and the joint decision. In terms of work performance the level of personal performance and organization performance was considered high. The hypothesis testing revealed factors motivating the work performance and teamwork behavior that affected the performance of the employees at the .0 5 level statistical significance. The incentive factors affecting performance included the nature of work work progress salary income work conditions and work security. Teamwork behavioral factors affected distributed leadership and joint decision.

The purposes of the study on influence of motivational factors towards on organizational loyalty and performance of operational personnel in health science group in an autonomous university were to 1) study the influence of motivational factors on organizational loyalty among operational personnel and 2) to study the influence of motivational factors on the performance of operational personnel. The questionnaire was applied for data collection with the reliability acquired through Alpha Coefficient of 0.982 which was used to tryout with 30 people and collect data from 124 operational staff in health science group in a state-run university located at Chulapat building (source: Office of Personnel of Faculty of Allied Health Sciences Faculty of Nursing Faculty of Nursing and Faculty of Sports Science January 31 2017). This research is a descriptive research. The data obtained from the researchers questionnaire was analyzed by statistical analysis program including percentage analysis is used to analyze the individual factors mean used for interpreting various data and standard deviation to interpret data in various areas and multiple linear regression for testing the hypothesis as well as Pearson correlation. The research revealed that the hypothesis testing on motivational factors towards organizational loyalty and work performance of operational personnel in health science group in an autonomous university included 1 ) work success 2) work progress 3) acceptance 4) responsibilities and 5) job description while supporting factors included 1) salaries 2) advancement opportunities 3) relationships with others 4) status 5) policy and administration 6) work environment 7) work security and safety which influenced on organizational loyalty and performance of operating personnel in health science group at the 0.05 level of significance.

The objective of this research work was to arrange a performance measurement for finding factors which will have influence on the capacity of Faculty of Engineering Rajamangala University of Technology Phra Nakhon leading it to become a digital university. The results of making a survey on the data from the personnel of the Faculty of Engineering showed that: the factor that had the most influence on the capacity of the Faculty of Engineering Rajamangala University of Technology Phra Nakhon was the factor of knowledge and attitudes (the mean was 3.61 which stood at the level of comments very); regarding the level of comments this was followed by the factor that had influence on the capacity of the Faculty of Engineering in terms of the environment in the organization (the overall mean was 3.49 which stood at the level of comments moderate); the factor that had influence on the capacity of the Faculty of Engineering in terms of participation came in the last place (the mean was 3.41 which stood at the level of comments moderate). The basics results obtained from this research work will be partly used as an approach to help improve the processes of the Faculty of Engineering. This will support stepping into becoming a digital university in the future.

The purpose of this research was to investigate cooling water profile that effect to coefficient of performance of spilt type air- conditioning system. Air conditioner size of 12000 Btu/h was used in this experiment. There are three experiment of cooling water profiles in this work such as water spray water drop and heat exchanger profile. The ambient temperature conditions were controlled at 35 40 43 and 45 oC. The results of this study were found that heat exchanger profile had the highest average coefficient of performance and energy efficiency as 4.94 and 9.15 Btu/Wh which increased as 20.1% and 8.47% respectively when comparing with the normal working.

This thesis proposes technical performance evaluation and economic decence for the combination of harmonic correction devices in Industry. Currently an electronic device is popularly applied in power network. Although it is a higher performance device than the existing device it still causes the power quality issues and then network failure. Especially harmonic disturbance in the network it is a harmonic source that generates harmonic current into the network. Many types and solutions are available in the present time therefore the suitable and optimal financial solution must be considered. A network model for the analysis of harmonic correction devices suitable solutions and optimal financial has been established in the simulation software that bases on the power and Break Even Point (BEP) equations. The results of analysis shown that the performance of harmonic correction devices suitable solution and BEP of investment in match to the using of a detuned filter bank and an active harmonic filter (case 8) thus these information will be valued for the end-user.
