This article aims at reviewing literature and supposing the hypotheses that present a conceptual framework of a causal relationship model of factors influencing the development of local administrative organizations into high performance organizations in Thailand. From the literature reviews some important points to be tested were found as follows: 1. The compositions of local administrative organizations development into high performance organizations consisted of 6 factors: 1) Total Management Quality; 2) Openness and Action Orientation; 3) Long-term Orientation; 4) Local Innovation Continuous Improvement and Renewal; 5) Quality of Human Resource Management System and 6) Readiness for Change of local Personnel. 2. The causal relationship model of factors influencing the development of local administrative organizations into high performance organizations are as follows: 1) Transformational leadership has a positive direct effect on high performance local administrative organizations; 2) Organizational culture has a positive direct effect on high performance local administrative organizations; 3) Organizational structure and design have a positive direct effect on high performance local administrative organizations and 4) Transformational leadership has a positive indirect effect on high performance local administrative organizations through organizational culture and organizational structure and design. This framework can be used to study and test against empirical data.

The purpose of this research is to study the relationship between spiritual intelligence and competencies of Thai professional accountants. Questionnaires were collected from 401 Thai professional accountants who attended the training with the Federation of Accounting Professions under the Royal Patronage of His Majesty the King. This research used partial least squares structural equation modeling (PLS-SEM) to study the relationship between spiritual intelligence and competencies of Thai professional accountants through the mediating variables including role of work-life balance work stress self-efficacy and job satisfaction. The results showed that spiritual intelligence has a positive relationship in statistical significant with competencies of Thai professional accountants which can be explained by the role of self-efficacy and job satisfaction. Except for work-life balance and work-stress they are 2 of 4 variables that do not have any positive relationship in statistical significant with spiritual intelligence. Furthermore the results showed that competencies of Thai professional accountants have positive relationship in statistical significant with job performance. This research is the first study that provides empirical evidence about the relationship between spiritual intelligence and competencies of Thai professional accountants. This study helped to confirm previous studies about the relationship between spiritual intelligence and competencies in personnel in the organization again. We will be able to used as a guideline for developing competencies with spiritual intelligence for Thai professional accountants. Furthermore we will obtain new knowledge for educational institutions in Thailand at various levels in opening relevant courses in order to prepare students to be professional accountants in the needs of organizations and ASEAN. They can confidently adjust to be professional accountants in accordance with the standards increase job performance in the era 4.0 with confidence and sustainability.

Rail transport is a type of transportation that strongly influences economic due to its ability to transport a large number of passengers and products per trip relying on diesel-electric engines. The objectives of this thesis were set to investigate and develop the electrical performance tracking system of long-distance diesel electric locomotives and compare the electrical performance measured by the diesel electric locomotive performance tracking system and measured from the measuring instrument at Diesel Engine Maintenance Station in Bang Sue. The electric diesel locomotive no. 4513 (Cummins KTA50-L) was selected as the study subject of the experimentation. The results showed that the power loss of the diesel electric locomotive from the conversion of alternating current to direct current was inversely proportional to the engine speed. The power losses between the low and high engine speeds were equal to 77.11 and 2.49 percent respectively. The above data reflects the limitation of diesel electric engine performance and should lead to the construction of a database for making decision on the right engine selection suitable for the towing load of the locomotive.

Weather forecasts are very necessary to predict the future weather conditions. The important thing in forecasting is the model and variables. The model used in the forecasting must be accurate and effective. In addition the variables used in forecasting must be comprehensive and appropriate to be able to represent the forecast. The initial conditions for forecasting must be appropriate and reliable. There are many methods to generate the initial conditions in forecasting. To generate the initial conditions for winter monsoon prediction with Kalman Filtering method which is a method used to predict the status of various systems and able to create values of variables used in forecasting to have a variety of similarities can be used as a starting variable in forecasting very well. In this research the winter monsoon prediction by the Shallow Water Model and validating the initial conditions by Root Mean Square Error (RMSE). The result of weather prediction in the winter monsoon can be used the Kalman Filtering method for generate the initial conditions.

The purpose of the study on decision making to buy Arowana fish online was to investigate the customers’ purchasing behavior on Arowana fish through online selling channels. This is a survey research study and the tools used in the study were the online surves generated from the review of relevant research papers. The data were analyzed from 311 customers using frequency mean standard deviation K-Mean clustering grouping. The research result revealed that most of the customers were males between 31-40 years old with buying reasons for the beauty of the fish called Malaysian Golden Arowana with the price between 5000 - 10000 baht. According to the study on the factors affecting the decision to buy Arowana fish via the online channel the respondents had a high level of decisionmaking on marketing mix in all aspects including the product physical environment price distribution channel process marketing promotion and person.

The respondents who were less than 20 years old bought high back Arowana fish for the price of lower than 5000 baht as well as those from 20 to 30 years old. The customers who were 31 - 40 41-50 51-60 and over 60 years old bought golden Malaysian Arowana on the price ranges from lower than 5000-10000 baht 20000 baht or more 5000 baht and lower and 10000 - 20000 baht respectively. By segmenting customers by means of K-Mean Clustering it was found that in Group 1 the majority were males aged 41- to 50 years old with the reasons to buy for the beauty of golden Malaysian Arowana fish with the price of 5000 - 10000 baht. Group 2 was mainly males 21 - 30 years old with the reasons to buy for the beauty of golden Malaysian Arowana fish with the price of lower than 5000 baht. Group 3 was mainly males who were 21 to 30 years old with the reasons to buy for the beauty of golden Malaysian Arowana fish with the price of less than 5000 baht. The fourth group was all males aged from 31 to 40 years old with the reasons to buy for the beauty of golden Malaysian Arowana fish with the price of 5000 - 10000
