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.

Differential evolution is one of the most efficient optimization algorithms for solving complication problems including single objective multiobjective and many-objective optimization. It is a stochastic population-based search approach for optimization over the continuous space. The main advantages of differential evolution are simplicity robustness and high speed of convergence. The Advanced Fuzzy-based Multiobjective Differential Evolution (AFMDE) that exploits three performance metrics specifically hypervolume spacing and maximum spread to measure the state of the evolution process. The fuzzy inference rules are applied to these metrics in order to adaptively adjust the associated control parameters of the chosen mutation strategy used in AFMDE. The optimization algorithm will stop the evolution process if the number of iterations reaches the stopping criteria which usually is the maximum number of iterations. Then the optimization algorithm delivers the optimal solution founded. However sometimes if the maximum number of iterations is not appropriately defined the found solutions may not be the optimal ones. In case of the optimization algorithm has found the optimal solutions but it must continue the evolution process because the stopping criteria are not met. This can cause unnecessary using of high computational resources and time-consuming. Therefore this research study proposed the stopping criteria based on performance metrics feedback for AFMDE. The efficiency of the proposed criteria combined with AFMDE is evaluated on the well-known ZDT benchmark test suites.

Changing in the present era led Rajamangala University of Technology Phra Nakhon needed to emphasize on its policies to comply with the national policy related to the creative ideas for the development of innovations internet learning forming Smart Farmer & Smart Startup and the specialist labors. Thus this was for the Thai society to step into the “innovation driven economy.” In response to the national policy it aimed at the university development toward basic changes in persons and organization adjustment to become university 4.0 together with the academic line to answer for the needs of problem solution and develop to become equivalent with other universities. According to this significance the researcher interested to study on the relationship among transformational leadership the follower’s adjustment and the follower’s performance. The research objectives were 1) to study on the relationship between the transformational leadership and the follower’s adjustment and; 2) to study on the relationship between the follower’s adjustment and the follower’s performance. Thus this would be used as the guideline to develop the administrative tasks in the organization and any units for the effectiveness and efficiency. This quantitative research adopted questionnaire as the research instrument. Data was collected from 270 samples. Data analysis was done through the use of CFA to seek for the relationship of the variables and the hypotheses were tested by the Structural Equation Modeling: SEM. The result of the research shows that transformational leadership with ideology forming inspiration intellectual stimulation and individual consideration had lesser than 5 p-value in all aspects. Thus it can be concluded that all 4 forms of the transformational leadership had the positive relationship with the follower’s adjustment while the follower’s adjustment also had the positive relationship with the follower’s performance. Therefore according to the research results the organization leader shall forsee and aware on the significance of leadership in form of leader with ideology vision ability in emotional management and good ethic motivated for the work inspiration forming attitude and stimulate the soul of followers to have creative ideas and new innovations amid the condition of changes in the present era.

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.
