The purposes of this research were to study the properties of Tei Panan Root suitable for the development of home decor products inspired by Koh Yo woven fabric patterns to conduct the development of home decor from Tei Panan material and to study the satisfaction of experts with home decoration products from Tei Panan root material inspired by the Koh Yo woven fabric patterns. The research began by studying the properties of Tei Panan root material and developing Tei Panan root materials. The most suitable formula was selected. The properties of Tei Panan root material were evaluated to select the most suitable pattern. The researcher designed the home decoration from Tei Panan material inspired by Koh Yo woven fabric pattern dividing to 3 types of lamps including hanging lamps wall lamps and table lamps (3 forms for each type). Five experts were appointed to select the most suitable form for each type. Then home decoration products were created from Tei Panan root material inspired by Koh Yo woven fabric pattern by assigning 10 experts consisting of 5 textile experts and 5 design experts and the product satisfaction was inquired about. The results showed that in the development of properties of Tei Panan root material the most suitable formula was formula 3 and the most suitable pattern was Su Ban Ni Ka pattern (n= 3 60%). The result of the development of home decoration from Panan material inspired by Koh Yo woven fabric pattern classifying hanging lamp form 3 (n=4 80%) wall lamp form 2 (n= 3 60%)and table lamp form 3 (n=3 60%). All 10 experts were satisfied with the home decoration products from Tei Panan root material inspired by Koh Yo woven fabric pattern with highest level in all aspects of satisfaction such as materials design product usability and overall satisfaction with a mean score of 4.56.

The study of the efficiency of fuel consumption by adjusting the fuel injection pressure is basically one optimization method to maximize the engine combustion. In this current study the Honda wave 110 cc. engine has been used to test in particular the fuel injection by adjusting the pressure of injector. To control the pressure of injection was made by automatic valve injectors with three different pneumatic pressure which were 2 2.5 and 3 bars respectively and the similar running distance of 5km. The results showed that at 2 bars the obtained fuel saving was 1020.68 km/L and the speed at 25.23 km/h which corresponded to the highest CO2 emissions during the engine combustion.

Developing women’s clothing design from marigold-dyed linen. The objectives of the project were : 1) to study about linen dying technique with marigold with various kinds of mordant 2) to design and develop women’s clothing from marigold-dyed linen 3) to study the satisfaction of representative samples for the women’s clothing design from marigold-dyed linen. Using simple random sampling method analyzing the data with statistics percentage mean and deviation standard. The sample groups are selected from working women in Dusit District Suan Chitlada Subdistrict and students from Rajamangala University of Technology Phra Nakhon in total 100 participants. Research instruments are questionnaire and 2 women’s clothing prototypes one was dyed with natural mordant and the other chemical mordant. The results indicated that most of the samples aged from 25 and above single graduated with bachelor degree are general office workers and students and earn less than 15000 baht. The result also revealed the satisfaction for the women’s clothing design from marigold-dyed linen a design which was dyed with both natural and chemical mordant. The participants are satisfied with the modern design suited for working age and very useful at a high level with means of 4.07 and 4.05 natural and chemical mordant respectively. Considering the overall result the participant tended to be satisfied with natural mordant dyed dress more with a mean of 4.07
