The data collected were analyzed by frequency percentage mean standard deviation Pearson Product Moment Correlation Coefficient and multiple regression equations. The research results revealed that the organizational factors affecting perceived mission of Rajamangala University of Technology Phra Nakhon personnel included factors such as 1) strategic aspect 2) system aspect 3) Staff aspect 4) Style aspect and 5) skill aspect which influenced the perception of the mission of Rajamangala University of Technology Phra Nakhon staffs at 0.05 level of statistical significance. This could be explained jointly by the mission statement in the overall at 66.2 percent. However the organizational aspect and value aspect had no influence on the perceived mission of Rajamangala University of Technology Phra Nakhon staffs.

The purposes of this research were: 1) to study the effectiveness of customer relationship management influence the customer trust on service quality on private vehicle inspection service in Phra Nakorn Si Ayutthaya 2) to study the customer loyalty influence the customer trust on service quality on private vehicle inspection service in Phra Nakorn Si Ayutthaya. 3) to study the effectiveness of customer relationship management influence the customer loyalty on private vehicle inspection service in Phra Nakorn Si Ayutthaya. The samples in this study were 325 Banpan private vehicle inspection service’s customers in Sena district Phra Nakorn Si Ayutthaya province. The data were analyzed by using frequency percentage mean standard deviation and Multiple Regression Analysis. The results found that the opinion levels on effectiveness of customer relationship management in overall and each aspect was found that the customer engagement customer hearing customer suggestion customer retention and customer prospecting were at the high level. The opinions level toward the customer trust on service quality was found at highest level in overall. The opinions level toward the customer loyalty was found at high level in overall. The result of hypothesis test found that the effectiveness of customer relationship management in customer suggestion customer retention and customer prospecting were influenced the customer trust on service quality. However the customer engagement and customer hearing were not influenced the customer trust on service quality. The customer trust on service quality were influenced the customer loyalty. The effectiveness of customer relationship management in customer engagement customer suggestion customer retention and customer prospecting were influenced the customer loyalty however the customer hearing were not influenced the customer loyalty.

Because school administrators play an important role in the management of schools to achieve their objectives effectively. This research aims to study leadership of school administrators factors relating to leadership leadership and relationship between leadership and factors affecting leadership of school administrators. The research design was based on the correlation research . The samples used in the study were 185 of the school administrators and deputy director. The research instrument was a questionnaire. Statistics used in data analysis were frequency percentage mean standard deviation and pearson correlation. Research results found that 1) The administrators of the schools in the secondary education area 1 had the form of four types of leadership. The results showed that the patterns of leadership reflected in the supportive leadership style. The highest average was followed by participatory leadership. Leadership focused on success. 2) The results of the study on the level of factors related to the leadership of the school showed that the four factors were the opinions of the target group. It is important to have leadership in mind. The average score on the highest level of leadership was followed by group characteristics organizational characteristics and external environment. And 3) the relationship between leadership and related factors of the leadership of the school administrators was found to be positively correlated in all aspects.

This project is intended as a teaching medium air conditioning system and simulation of air conditioning system problems. Some of them have been modified to suit their teaching needs. Arduino microcontrollers are used to control the system. By starting the study of the air conditioning system thoroughly. The microcontroller is written to control the operation of devices like the air conditioning system when the system malfunction. It will be used to analyze the problems of air conditioning. The experimental set will display the voltage and current. The connection points of the air conditioning problem analysis. When the symptoms are bad. The analyst can solve the problem by connecting or pressing the button of the device. The results of the project. The test will measure the difference of the air conditioning unit. And read the amount of current and volume in the system. To diagnose abnormalities and choose a solution to the problem from the kit system that can be displayed to solve the problem that the analyst was correct or not with the LED status light. Based on the performance test a demonstration kit for the demonstration of efficiency of the air conditioning system was provided to 10 experienced air conditioning technicians. 80s of issues. The reliability of the demonstration set and the efficiency of the simulator case study of the electrical system in air conditioning systems is acceptable

Molds manufacturing to produce chloroprene rubber product with carbon steel over time the mold surface will wear. From the original. The practice in the industry often uses surface coatings (Hard chrome method) or change materials to create molds. Therefore this research is to study the effect of corrosion or wear. To see the size of surface mold changed in the experiment. Based on a tolerance of 0.1 millimeters at the molding point and after molding in the actual work conditions of a 2-3 weeks sample and mold size measurement. At less than 10 times the permissible coordinate value is 0.01 millimeters. The experiment found that. The wear of carbon steel molds was formed with chloroprene rubber. It has a very small value when referenced to the tolerance coordinates which is not significantly reduced when the rubber specimen size is determined. The allowance range is 10 μm to 100 μm. Therefore the design of chloroprene rubber to make molds with carbon steel. It can help reduce production costs. Without replacing with corrosion-resistant materials or adding coatings.
