The purpose of this study was to investigate the influence of job satisfaction concerning the work performance of Ayudhya Capital Auto Lease Public Company Limited (Krungsri Auto) employees after the merger. The sample consisted of 2468 employees of Ayudhya Capital Auto Lease Public Company Limited (Krungsri Auto Personnel Department 2016). According to Krejcie and Morgan (1970) the samples used in the study were 331 who were asked to provide data through a questionnaire developed by the researcher. Its reliability regarding the Alpha value was .939 and the analysis of the respondents’ data frequency and percentage mean and standard deviation were applied. The analysis of data on the job satisfaction and Krungsri Auto employees’ performance relied on the inferential statistics while the hypothesis was tested by using multiple regression analysis and the results were as follows. The analysis of general education data of the population showed that most respondents were females between 31-40 years old with bachelors’ degrees and were in the entry-level positions for 1-5 years earning 15000 – 30000 Baht. It was found that Krungsri Auto employees’ the work motivation in the overall staff was very high. The highest was the aspect of the work characteristics followed by work success work responsibility work atmosphere salary and welfare and good governance which were all in high levels. However the acceptance aspect was in the moderate level. As for Krungsri Auto employees’ job satisfaction it was found that the satisfaction of employees in terms of the career security work atmosphere good governance salary and welfare were at high level. The job satisfaction on the policy and administration (X6) leadership (X11) opportunities and advancement (X4) relationships with colleagues (X8) and personnel acceptance (X5) could be written as raw score (B) and standard score (Bata) of the multiple regression equation used to predict the satisfaction of the personnel performance that influences the performance of the employees. After the merger Bank of Ayudhya was selected by using the predictive equation as the following raw score. = (Y) 1.138+.201 (X6)+.155 (X11)+.106 (X4)+.142 (X8) + .087 (X5) Suggestions for further research are as follows. 1. Executives should have a clear salary management policy adequate to ensure a stable working atmosphere and organizational commitment. 2. The organization should foster the motivation for better work performance. 3. The organization should ensure the employees’ confidence that after the business merging the employees will also have the same work stability recognized good working conditions and appropriate welfare for the performance.

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

The objectives of this research are to propose an efficient and proper model that fits the cassava and rubber yields data. A generalized estimating equation (GEE) and a linear mixed model (LMM) with spatial correlation following the conditional autoregressive model (CAR) were adopted. The dependent variables are the cassava and rubber yields collected each month in every province of Thailand. The factors considered are rainfall averaged temperatures and regions. The results from GEE and LMM show that the factors influencing on the cassava and rubber yields are rainfall averaged temperature and region. Both GEE and LMM fit the correlated data. The GEE is used to explain the influence of factors on the yields in all provinces while the LMM is used to explain the influence of factors on the yields in each province.

Nowadays a disc brake is one of important auto parts for motorbike cycle industry which effected directly to life safety. As the result this project aims to test the performance of the disc brake in order to study the physical disc brake that effects to braking distance and to be an alternative for testing the brake disc. Therefore the braking performance tester was designed and created in the single dynamometer which was not over 9.70•kgm2 as the moments of inertia of motorcycles. Regarding JASO T204:2001 this test was focused on the 3 different types of brake discs (i.e. normal type grooving type and perforated type). The tested temperature was at normal state of the brake disc temperature (60°C - 80 °C) and at high state (more than 100 °C). The braking force from 9.81N to 34.33N at master cylinder was tested. The result revealed that at normal temperature the braking performance of the three disc brakes (normal type grooving type and perforated type) was at 7.29 9.10 และ 9.50 m/sec2 per 1m2 of contact surface areas respectively. However the brake performance at high temperature was at 7.21 9.03 และ 9.46 m/sec2 per 1m2 of contact surface areas respectively. This result reveals that the most efficient disc brake at normal temperature was perforated type of disc brake which was 30.32% different from normal type of disc brake. Likewise; the perforated type of disc brake was the most performance disc brake at high temperature which was different from normal type of disc brake at 31.21%

The purpose of this study is to study the factors that affect the accounting performance of the quality accounting office. The population group is the accountants operating in the 160 quality accounting firms. 115 sample are collected and the sample size is calculated using Taro formula. The data is analyzed using descriptive statistics including frequency percentage mean and standard deviation and inferential statistics including Independent sample T-test One Way ANOVA Pearsons Correlation Coefficient and Multiple Regression Analysis. The study results showed that of the overall and individual motivation factors Motivation factors and Supporting factors affected the accounting performance of the quality accounting offices at the highest level while the sample group had accounting skills in general in the highest level. The hypothesis testing found that 1) age education level and the different incomes affected the efficiency of accounting operations of different quality accounting firms 2) Motivation and Supportive factors had no influence on the efficiency of accounting performance of quality accounting firms and 3) professional knowledge professional skills and professional attitude had a positive influence on the efficiency of accounting operations of the quality accounting offices.
