This paper presents an assessment of the quality of electricity transmission and distribution system to supply power to the industrial area. The objective is to analyze the power quality that customer in the industrial area need high level. By analyzing the power quality of Provincial Electricity Authority (PEA) in transmission system 115 kV distribution system 22 kV and 400/230 volt in Rojana industrial park from power quality meters. The study concluded that the phenomenon occurs continuously consist of RMS voltage power frequency voltage unbalance short term flicker long term flicker Harmonic meet the standards applied to all. The phenomenon occurs temporary consist of transient voltage dip voltage swell interruption in the conclusion the power quality problems caused by voltage dip most especially with loads which are sensitive to voltage. From the moment the measurement showed that the voltage dip on transmission system 115 kV maximum of 19 times. The voltage dip that occur including three voltage level of 30 times there are events that do not pass SEMI F47 standard 12 times or 40%.

This Research purposes assessment of lightning performance on transmission system 69 kV in Metropolitan Electricity Authority (MEA). The case studies illustrated the lightning strike to direct top pole in order to guideline considering the critical flashover voltage value of insulator is able to withstand it and improvement lighting protection in the future. This solution analyzes using the Alternative Transient Program-Electromagnetic Transient Program (ATP-EMTP). The result found that voltage across insulator before and after improvement lightning protection by external ground wire. Factor effect to voltage across the insulators is the tower footing resistance wave of lightning current and interval between towers. It depends on relation with front time of wave. The analysis economics is very important. This Research is studying interruption cost of outage since back flashover so analysis the break even point of the installation external ground. The result found upon improvement lightning protection by installed external ground. The pay back period of that is 9 years installed ago. This result can conclusion is external ground able reduction interruption costs of outage.

The objectives of this research are: (1) to investigate the potential of agrotourism project sites in Bangkok and its vicinity that are officially recognized as following the principles of the Philosophy of Sufficiency Economy; (2) to create a good relationship between the researcher and the local community tourism academics experts and farmers. This study was conducted by means of semi-structured interviews and questionnaires. The participants are stakeholders including community leaders and agricultural owners. Content analysis was employed to analyze the qualitative data. Descriptive statistics (percentage and mean) was employed to present the quantitative data. The results of this research reveal that: (1) The strengths of the agro-tourism project sites include knowledge of the new agriculture theory and the expertise of owners. (2) The weaknesses include lack of services for tourists rest areas and parking. (3) Base on all 34 indicators of 4 factors the overall averages scores of both agricultural sites are in the intermediate level at 2.24 and 2.11 respectively. (4) The most important factor determining the potential of agro-tourism sites is good attractive location and the least important factor is lack of service.

The objectives of this study were to determine the need to develop human resources for employees in the rubber industrial in Thailand and to compare the difference of need for human resource development of employees in the rubber industrial who have differences of personal status.The study was conducted as a survey research by using a questionnaire to collect data. The samples of this research were employees who work in the rubber industry of Thailand. result was 400. The statistics treatments included frequency percentage mean standard deviation and one-way analysis of variance. Research findings: The need to develop human resources for employees in the rubber industrial in Thailand was overall at high level. Considering in specific aspects found that the need of employee to develop the most is their work environment which had the highest mean followed by the need to develop self development training and education respectively. And Employees with difference in personal status such sex age and marriage status and income level have no different in the need of human resources development. While employees with difference in educational level work experience and working position have a difference of need in human resources development.

The objectives of this research were to create and assess the teaching of Phra Dabos disciples’ training course on satellite dish installation by comparing between the pre-learning and post-learning achievement and evaluating Phra Dabos Disciples’ satisfaction. The sample of this study was 15 Electronic Phra Dabos Disciples’ students Phra Dabos School enrolling in Satellite Dish Installation course in the semester 1/2013. Achievement test and satisfaction questionnaires were used to collect the data. Paired t-test means standard deviation and percentage were employed to analyze the data. Reliability difficulty and discrimination of the test were investigated. As for training course creation the instructional method of De Cecco’s concept was used and adapted in this research study. After training it was found that Phra Dabos Disciples’ students gained higher post-learning achievement scores than those of the pre-learning at the statistically significant level at 0.05. The assessment of the Phra Dabos Disciples’ satisfaction toward training course showed that the Phra Dabos Disciples’ students were overall highly satisfied with the course.
