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.

The purpose of this research was to investigate the optimum heat temperature for the EC500 wax cured basecoat extrusion from all castings without waxing in the mortar. To reduce waste when the casting mortar through the casting process Silver Sterling 925 silver jewelry company Muang District Chiang Mai where the waste is caused by waxing outflow. The imperfections and leave waxing inside. Experiment with high temperature heat in mortar. And analyze the quality of work surface after casting with microscope. To find defects such as droplets and porosities caused by a range of temperatures. Temperature of baking mortar There is a difference from the conventional waxing mortar temperature. That is outflow of EC500 type wax. In the mortar to live. High heat The results of the 100 sample EC500 wax samples were tested at a temperature of 25 ° C. The mortar temperature was 700 ° C. 60 percent of waste was found the mortar was laid at 750 ° C 54 percent of waste was found. The mortar temperature was 800 ° C 32 percent waste was found the mortar temperature was 850° C Detecting 1 percent waste. The results of the study show that heat temperatures of up to 850 ° C can solve the problem of casting sterling silver alloys from the EC500 wax model. Finds the least waste.

Aluminium was used in many industrial applications due to good properties such as ductile high corrosion resistant and high electrical conductivity. Since wear resistance of aluminium was very poor so that it was a limitation of using this material in several conditions. In this research aluminium was improved the wear resistance properties by using anodizing process and adding some titanium dioxide particles on the surface. The effect of anodizing process duration on the wear resistence property was studied. It was found that the process duration and amount of titanium dioxide play the important role on improvement of tribological properties of aluminium.

The research of strategic accounting information systems of technology and targeted industry groups to Thailand 4.0 was aimed at studying 1) strategic accounting information systems of technology and targeted industry groups to Thailand 4.0 and 2) factors related to strategic accounting information systems of technology and targeted industry groups to Thailand 4.0. The questionnaires were constructed as a research tool for collecting data from 400 entrepreneurs in technology and targeted industry groups. The data was statistically analyzed by frequency distribution percentage mean standard deviation and multiple classification analysis: MCA. The research findings indicated that most entrepreneurs in the technology and targeted industry groups were in food agriculture and biotechnology. Their capital to run business at the present time was between baht 1000001-1500000. The average number of employees was 4.75. They had income of baht 5000001-7500000 per year. Most of them employed companies or organizations to develop their own accounting information systems and their practicable period was 7.61 years. The capacity accounting information systems was totally at high level (  =3.64). Also the usability of accounting information systems was totally at high level (  =3.67) whose data collection was at  =4.00 data processing at  =3.66 data controlling at  =3.53 and information generation at  =3.51 respectively. The hypothesis testing results at statistical significance of 0.05 showed that the capacity of accounting information systems was the vital factor relating to data collection data processing data controlling and information generation and the annual income of entrepreneurs in strategic accounting information systems to Thailand 4.0 was related to data collection data processing and strategic accounting information systems to Thailand 4.0.

This research aims to study the Mirai Botnet working process which made high bandwidth impacted to Internet system. From 90000 clients of Deutsche Telekom cannot access to Internet that overall bandwidth growth nearly 1 TB per second in the history DDoS attacking behavior. As Mirai exaggerated attacking to ISPs and may be involved UniNet as a big umbrella which RMUTP network interconnected as well. The author would like to study in depth to several weak points of the end devices or IoT on Internet. In the Mirai code used the IoT devices such as the Internet cameras the CPUs based on ARM ARM7 Motorola 6800 SPC PowerPC X86 and SuperH (SH4). As the results of valuable attacking code studied based-on IPV4 attack without IPV6. The source code has more than 5500 lines with 16 files and 138 functions included 62 set of user accounts and passwords. Usage the 9 flooding techniques for port attacking via 22 23 and 80 with the IP scanning exceptions for DoD IANA GE and HP IP addresses. The Internet camera devices have to disable 22 23 and 80 ports or doing suitable usability techniques to manage for several flooding protection from system harmfully.
