This paper presents a program developed for calculating magnetic field intensity of high voltage transmission line and high voltage distribution lines. This program was developed with Microsoft Visual Basic and Microsoft Access program was used to store the database of the peak ratings current height and space of transmission lines. The developed program was able to calculate magnetic field intensity of high voltage transmission line and high voltage distribution lines according to 2 standards of Provincial Electricity (PEA): “A 22 kV Single Conductor Circuit High Voltage Distribution System” and “115 kV Single Conductor Circuit High Voltage Transmission System”. The program was able to select structure of the electrical system to be calculated as well as types and specification of Transmission line from the stored database that corresponded with the structure. The calculated output waveforms were displayed on computer monitor. Results from the developed program enable more convenient and faster calculations of magnetic field intensity of high voltage transmission line and high voltage distribution lines and are useful for analysis of possible impacts on electric and electronic devices.

The purposes of this study were 1) to create a construction of design program for practical skills system of engine repairing 2) to determine the quality of design program for practical skills system of engine repairing 3) to evaluate the users’ satisfaction of a design program for practical skills system of engine repairing. The sample used in this study consisted of 30 lecturers from automotive division university and 39 lecturers from the office of vocational education commission. The tools used in this study were the quality assessment for practical skills system of engine repairing and the satisfaction assessment of the users to design program for practical skills system of engine repairing. The statistics used for data analysis were percentage mean standard deviation and t-test for dependent samples. The results of the study were as follows: 1) the quality of were very good level design program of for practical skills system of engine repairing( = 4.70 S.D. = 0.21). 2) User’s satisfaction level after accessing the program were very good level ( = 4.60 S.D. = 0.11). 3) The results were compared to assess the satisfaction level of the user from Nakhonphanom university and the office of vocational education commission towards of design program for practical skills system of engine repairing in the field of design content and application found that in each of the satisfaction level did not differ significantly at .05 level. 4) The results were compared to assess the satisfaction level of industrial community education and technical college towards of design program for practical skills system of engine repairing in the field of design content and the application found that in each of the satisfaction level did not difference at significance level .05

The purposes of this research were 1) Study behavior and demand of consumers for handicraft product from palm leaf. 2) Design and development handicraft product from palm Leaf. 3) Study of consumer satisfaction for handicraft product from palm Leaf. The results found that. the community of housewife at Tambon Takaok choose artificial flowers and bag. Demand of the buyer in Tall vase flower arrangements Image of Buddha decorate with flower spherical vase flower arrangements and corsages handbag purse and cosmetic bag. Pass the tested to Thai Community Product Standard.The result of customer satisfaction showed that the average highest satisfaction product was spherical vase flower arrangements corsages and tall vase flower arrangements. The average high satisfaction product was Image of Buddha decorate with flowercosmetic bagpurse and handbag .

The purpose of this research were 1) to study the environment of The Faculty of Industrial Textiles and Fashion Design at Rajamangala University of Technology Phra Nakhon as perceived by undergraduate students. in overall and 5aspects : lecturers teaching and learning management premises students services and students activities. 2) to compare perceived of the environment of the Faculty of Industrial Textiles and Fashion Design at Rajamangala University of Technology Phra Nakhon. In overall and 5 aspects classified by gender years of study student achievement and major of studies 416 under graduate students were used as samples. The instruments used in the study was a five-point 58 items rating scale questionnaire with the reliability of 0.97. The data were analyzed by mean percentage standard deviation and t-test. The results revealed that : 1) the environment of the Faculty of Industrial Textiles and Fashion Design at Rajamangala University of Technology Phra Nakhon as perceived by undergraduate students in overall and 5 aspects were at moderate level. 2) the environment of The Faculty of Industrial Textiles and Fashion Design at Rajamangala University of Technology Phra Nakhon as perceived by undergraduate students classified by gender years of study student achievement and faculties were significant different.

The purpose of this research is to improve the pepper mill for increasing performance. The characteristic of the pepper mill is a trapezoid shape. The structure is made of angle steel and stainless steel sheet. The motor used a power unit is 1 hp and send the power to the driving belt for driving the disc. There are new pattern of designed discs. The discs are made from stainless steels and have three different patterns on the surface of discs. Each test must measures the moisture contented of the pepper seeds. If the moisture is less than 9% can be milled. However if the moisture is more than 9% that must be taken pepper seeds to sunning or drying. The test is 10 sets in each set of test using two samples of pepper seeds. In each test pepper seeds must be weighted before the milling when they are milled the finish. After that they are brought the milled pepper seeds to a weight and separated a size. The sorting by size is 5 sizes as a less than 5 microns 150-250 microns 250-425 microns 150 microns 425 to 1000 and more than 1.00 mm. The results of research shown that pattern of discs will give the different pepper powder sizes
