Objectives of this study are (i) to investigate characteristics of a fuel injector and to establish the characteristic correlation for correcting the fuel injection rate calculated from the control signal of a fuel injector and (ii) to design and fabricate the fuel consumption monitoring system by measuring the control signal of fuel injector in conjunction with considering the obtained characteristic correlation to enhance accuracy of the measured fuel consumption rate. The characteristics of a fuel injector (maximum fuel injection rate of 270 cm3/min) e.g. engine speeds percentages of injector’s duty cycle and pressure differences between fuel rail and intake manifold were experimentally investigated on a test set in the laboratory. The study found that when the engine speed increased the fuel injection rate increased. When the percentages of infector’s duty cycle increased the increasing ratio was less than the one-to-one increasing ratio as a case of the ideal. Moreover when the pressure difference increased the fuel injection rate increased. After that the fuel consumption monitoring system was designed and fabricated based on the Arduino Mega 2560 microcontroller. Trip distance was measured by a GPS module. The real-time fuel consumption rate could be shown on a LCD display. All recorded data were stored onto a SD card for further data analysis. Finally the on-road-test validation was conducted by on the 2011 Mitsubishi Triton installed with the 4-cylinder gasoline engine with total displacement of 2351 cm3. It was found from that the average discrepancy of the measured fuel volume was ± 1.88% compared to the actual fuel volume obtained by measuring a decreasing volume of consumed fuel.

The purpose of this research was to design and carved soap products for gift and souvenirs and to study the opinions on the product design from carved soap products as gift souvenirs. The tool was questionnaire as the collect data from 7 experts and 100 samples. The data were analyzed by frequency percentage and mean in the form of tables and description as follow: 1. Most experts commented that should develop the product design from carved soap to difference from another one in the market. In addition the problem of creating product design from carved soap should be explain how to use chemicals to help maintaining. Then developmental guidelines should provide a number of useful uses and show polyester resurfacing on carved soap it is suitable because of keeping them were not broken. Moreover the polyester resin coating is too thick it was effect pattern craving more clearly Finally they chose the second sketching ideas because the product can hang on the wall and put in the table. It is quite look natural. 2. The samples opinions on the products of carved soap as a gift found that the design at the high level the average was at 4 . 1 5 . The overall aesthetic was at the highest level at 4.23 in terms of value and utility. The overall score was at 4.23.

This research Designing and Textile Materials Decorating for Apparels with Film Innovation. The objective is to study the use of film innovation and finishing materials for textiles. To design and decorate costume products with innovative films. This is a great way to showcase your knowledge and technology design and decorate your textiles for innovative costumes. The research instruments were 3 product designs and a satisfaction questionnaire for trainees. The samples used in the research were 12 randomly selected randomized individuals at the Faculty of Home Economics. Rajamangala University of Technology Phra Nakhon By analyzing data To find the average and average values. Summarize results in tabular form. And writing The tools used to collect data were: 1) three types of costume design namely jacket and skirt 2) three types of costume designs 3) On August 13 2018 at the Faculty of Home Economics Rajamangala University of Technology Phra Nakhon. 1) Film innovation The material is made of polymer. Chemical composition Polyvinyl alcohol It is a thermoplastic with special properties. Biodegradable And fire like paper. It can also be dissolved in water. The embroidery machine is easy to emboss but does not make the fabric thick or hard. Embroidery Machine And its easier to pull off than paper. When embroidered. When to use the costume can be washed normally. Because the film will react with the decomposition of the film with water. By soaking the warm water. Allow the film to dissolve for 15 minutes. 2) Design and decorate the costume products with innovative film. Then 3 innovative products were developed namely shirt jacket skirt. 3) Technology Transfer A workshop was held on August 13 2018 at the Faculty of Home Economics. Rajamangala University of Technology Phra Nakhon Most participants were satisfied at the highest level in all questions.

The purpose of this study was to investigate the influence work performance and organizational commitment affecting the resignation of a public bank support in Bangkok. This is survey research was quantitative which its samples consisted of 310 support staff of a public bank in Bangkok responding to the questionnaire as a research tool. Frequency percentage means standard deviation and Multiple Regression Analysis was applied to achieve 0.05 significance level. The research revealed that the majority of the population was male aged 31-40 years old working as employees and had the average monthly income less than or equal to 15000 baht. They had been working with the bank less than 3 years. Largely the analysis of their work performance and organizational commitment as well as the resignation of the employees was at a high level. The hypothesis test showed that the performance factor did not influence the resignation trend of the support staff of a public bank in Bangkok. In addition their organizational commitment influenced the resignation tendency of a public bank in Bangkok.

The research on development of pattern of cotton by using weaving technique in type of Mudmee fabric for metrosexual menswear by method of cutting and connecting has the objectives to : 1) develop pattern of cotton by using weaving technique in type of Mudmee fabric; 2) design of metrosexual menswear by using cutting and connecting from developed Mudmee cotton; 3) design the brand and packaging product to increase product value; 4) survey satisfaction of target group. The researcher studied by using Art Nouveau concept and by designing the cotton pattern by using Mudmee weaving technique numbering three patterns binding to make pattern woven to be fabric in order to make menswear in metrosexual style by using the method of cutting and connecting prototype consisting of one set of vest two sets of suits and two sets of overcoats as well as designing of brand numbering five types at the same time The researcher designed packaging product in five types using in surveying satisfaction of target group of thirty persons: Designer Merchandiser Graphic designer Visual merchandiser and person having fabric weaving experience by method of purposive sampling analyzing data by using statistics percentage mean and standard deviation. The study result was found that most respondents were female aged 36-40 years single status most have taste of female gender having income of 45001 Baht onwards. The educational level was Bachelor Degree. Respondents previously bought and used products and accessories for clothes from Mudmee cotton. The types selected to buy the most were vests bags and shawls respectively. The occasions in wearing the most of all were important festivals selecting to buy clothes and accessories for clothes from cotton by using Mudmee weaving technique in each occasion price 500-1000 Baht per one piece. Most persons participating in deciding to buy were friends. The sets of clothes for the groups wishing to design in sets of woman clothes. The result of satisfaction analysis of target group towards development of cotton pattern by using Mudmee weaving technique for metrosexual menswear by using cutting and connecting method it was found that target group had satisfaction in much level ( x= 4.16). The result of satisfaction analysis of target group towards design of metrosexual menswear by using cutting and connecting method it was found that target group had satisfaction towards the clothes in every type in much level (x= 4.26). The type which had mean of the highest satisfaction in the three first types including suit in type No.3 (x = 4.31); the second was vest type No.1 (x= 4.29) and overcoat type No.4 (x= 4.27). The result of satisfaction analysis towards format of brand and packaging product it was found that target group had satisfaction in much level having x= 4.23 and 4.30 respectively.
