The problem of this research is automotive part companies do not have order because of the world economic crisis and effect to automotive industry. Automotive and automotive parts demand in the world decrease. Automotive Industry of Thailand received affect. Automotive part companies cannot export to foreign markets. The companies in Thailand need the forecasting of automotive part quantity demanded by foreign markets by selecting the most accurate model. This paper presents the modeling for forecasting demand for automotive part of foreign markets to Thailand with time series forecasting techniques. In this study the automotive part are wheels and including parts and accessories because Thailand exported the most in group of automotive parts. These five countries have consistently demanded the largest number of wheels and including parts and accessories are Japan China South Korea Germany and Indonesia. The research involves historical collecting data for the period of 1997 to 2008. The evaluation function of forecast error is used with MAPE. The results reveal that each country suits for each model in term of the chosen dimension. The government can use the forecasting demand for effective production planning by informing manufactures.

Studies on Thai Language Teachers’roles towards the Conservation and Promotion of the Thai Culture in the Rajamangala Institute of Technology Central Campuses The purposes of this research were : 1) To study the general environment and roles of Thai language teachers towards conservation and promotion of Thai culture among the students and the community 2) To compare the roles of Thai language teachers being classified by their teaching experiences and education levels towards the conservation and promotion of Thai culture. 3) To study Thai teachers’ problems and obstacles in carrying out the said task. Samples of the research were 160 Thai language teachers. The instruments of the research were questionnaires. The data analysis was done on SPSS program. The result of the research showed that : 1) Most Thai language teachers had not been trained in the conservation and promotion of Thai culture. 2) There was no signifecant difference at level of 0.5 between the roles of the two groups of Thai language teachers in the conservation and promotion of Thai culture. 3) The Thai language teachers’ problems and obstacles in carrying out the conservation and promotion were lack of opportunities to acquire trainings or to participate in seminars on Thai culture lack of budgets document texts and audiovisual aids on Thai culture.

The paper presents a development of monitoring system for a prototype wind turbine system. The proposed monitoring system is developed under Labview environment. The system can connect to the wind turbine online via internet. The system will collect the monitored values and install values into memory. Simultaneously the system can show the values in Real-Time. The operator can observe the wind turbine by the monitoring system and can take an action on time if the wind turbine is not working properly. The results of the monitoring system indicate that the monitoring system is be able to working properly the data can be used to investigate the wind turbine for system analysis. This is very important for wind turbine in order to supply energy to consumer stably.

The objective of this study was to investigate the attitude of Rajamangala Institute of Technology Bangkok Commercial Campus towards Thai Study subject. The population in this study was 265 undergraduates majoring in Accounting Program Infomation Systems program and Marketting program. who regitered in Thai Study subject during the academic years 2001 - 2003. The data were co;;ected by using an attitude test measusing students attitude in students Thai Study subject in four aspects nameley the contents the lecturers the learing activities and the teaching method/materials. The collected data were then analyzed by computing percentages averages and standdrad deviations and frequencies. The analyzed data were compured percentages averages and standard deviation and frequencies. The analyzed data were compared percentages and standard deviation and frequencies. The analyzed data were compared according to sex and students programs. The findings were presented using tables with description.

This work was aimed to improve the carbon black from waste tires for printing ink using coupling agent to disperse carbon black particle for making an oil-based offset ink. This experiment used 2 coupling agent these were silane coupling and derivative fatty acid and used to produce offset inks for the 7 formulas. Formula 1 Commercail carbon blackFormula 2 carbon black was not washed by Nitric acid formula 3 carbon black was not washed by Nitric acid and was added silane coupling agent formula 4 carbon black was not washed by Nitric acid and was added fatty acid modified emulsifier formula 5 carbon black was washed by nitric acid formula 6 carbon black was washed by nitric acid and was added silane coupling formula 7 carbon black was washed by nitric acid and was added fatty acid modified emulsifier. Bring all 6 formulas to test property to compare with offset ink commercial. First find the smallest particle of carbon black for 90 minutes. It was found that formula 4 took 20 minutes to make particles 12 micron and it is smalles particle of all. Then measured ink flow by Spread-O-Meter and measured diameter after 1 minute. It was found that formula 3 and 3 were 77 mm. and approximate commercial ink. Then measured tack of ink with Ink-O-Meter it was found that formula 2 3 4 6 and 7 were 2.4 and formula 5 was 2. Then measured viscosity and yield value of ink by Lary viscometer. It was found that formula 2 had 77 poise of ink viscosity and 670 dyne.s/cm2 of ink yield value that was approximate commercial ink. Finally measured Emulsification capacity (%) by Kershaw Water Pick up Tester. It was found that formula 6 had 74% and it was approximate commercial ink.
