This research is aimed to developed and evaluate a competency model of production engineer in the automotive industry. The data is collected from Amata City Rayong. The research is performed with two steps: 1) create an engineering competency in the automotive industry using Delphi technique with 17 experts. Then 2) review the engineering competency with the focus group of management staffs from automotive industry in Amata City Rayong. The statistics used in the analysis were percentile median and inter-quartile range. The results show that competency is consist of three parts. Part 1: management competency Part 2: functional competency Part 3: production engineering characteristic and consisted of four parts 1) the management of operational performance 2) production engineering 3) engineering knowledge 4) personal characteristics. Examining results in the competency model of production engineer in the automotive industry: the data is collected from Amata City Rayong created are appropriate and feasible in practice and performance as a performance model is built according to expert opinion.

Presently the rail transit system plays a major role in the commercial world that they currently use diesel engine not only causing to a lot of fuel consumption but also generating numerously pollution. Therefore this project aims to study the break-even point of investment under comparison of brake specific fuel consumption and pollution of locomotive engines. By experimental works there are 3 types of locomotive engine: Pielstick M.T.U. and Caterpillar which are the difference of the combustion chamber and the fuel injection systems. The simulation load on the static tests (Dynamometer) was used following the regulation characteristic curve which is standard of State Railway of Thailand. As a result of testing the engine using common rail type of fuel injection system M.T.U. was the lowest brake specific fuel consumption at all of engine by the average of all engine speed 206 g/kW-h of brake specific fuel consumption. It is lower than Caterpillar (Semi common rail with direct injection) which is 314 g/kW-h equivalent 34.39 % while Pielstick engine a mechanism fuel injection system is 389 g/kW-h equivalent 47.04 % For pollution area there are Hydrocarbon (HC) Nitrogen Oxide (NOX) and black smut. The engine with direct injection system relieved the previous substance less than the pre-combustion engine. Moreover the compound of carbon monoxide (CO) was found that the pre-combustion engine (Pielstick) discharged carbon monoxide (CO) less than the direct injection engine (Caterpillar) whereas the common rail engine emancipated same substan cenear by with the pre-combustion engine (Pielstick). However the new technology of the engines is high maintenance costs. Therefore a number of applications have to be needed to make a quantitative value for the investment.

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 objective of this study was to investigate factors related to budgeting in 2014 fiscal year: a case study of OTEPC. The samples were chief executive officers heads of the departments and 80 officers who were responsible for the project. A questionnaire was administered as the research instrument to collect data which were analyzed by percentage and Pearsons correlation. The findings were as follows: (1) In terms of personal factors it was found that most of them were female who were above 51 years old. They had master degrees and were in charge of heading the team as well as being the team staff with lower than six years experiences in handling budgeting tasks and had 30001 – 40000 baht salaries. (2) The relationship between handling budgeting study of OTEPC projects processes activities and achievements were in high level especially when the chief executive officers work agreed with the governmental policies followed by their legal exercises in relation with their decision making and officials’ participation which connected to those decisions. The government policies and its law exercise demonstrated low relationship as well as the governmental law exercise and the officials’ participation respectively.

The purposes of this study were to investigate the level of motivational factors of personnel working at the central administrative office of Rural Roads Department and compare their motivation on working. The research samples were 163 personnel working at the central administrative office of Rural Roads Department during January 2015. The data were analyzed by the frequency distribution percentage distribution mean (-μ) standard deviation using a computer software program to analyze the data collected from the questionnaire. The analysis of the study on motivational factors of personnel working at the central administrative office of Rural Roads Department revealed that most respondents were females (84.70%) with the age range between 31 and 40 years old. 75 persons (46.00%) held bachelor degrees while 124 persons (76.10%) had been working for five to ten years. 69 persons (42.30 %) were working in the level 2 to 7 and 82 persons (50.30%) earned 10001-20000 Baht per month 109 persons (66.90). The employees working at the central administrative office of Rural Roads Department had an average level of opinions towards motivational factors. When looking into each aspect it was found that work accomplishment work features acceptance and respect responsibilities and organizational expansion were relatively at high levels. Only work progress had an average level. Future studies should focus more on supportive factors concerning to work in order to obtain knowledge about the employees’ needs and satisfaction towards their workplace.
