The purposes of this research were 1) the comparison of tie-dye methods; Binding technique folding technique and stitching technique and 2) three kinds of fabric dyed; cotton linen and rayon comparison and 2 pattern design groups; geometrics and naturalistic patterns. There are 8 motifs were used; quadrangle trianglecircle heart form flower leaf butterfly and worm. The research tools were used; The assessment for 15 connoisseurs (connoisseurship model). Data were analyzed by the statistical package for the social science program and using mean percentage standard deviation one-way ANOVA and chi-square.The result of the study were that binding technique had mean 4.20the second was stitching technique had mean 4.10 and the last was folding technique had 3.69. The result of the tie-dye technique suitability comparative ranking for massproduct that the best technique is binding. The second was stitching technique and the last was folding technique. In this study there were comparative in 5 parts as follows 1.tie-dye method 2. pattern design 3. colour of fabric dyed 4. overall image of fabric dyed 5. capability of techniques.Binding technique folding technique and stitching technique on Cotton were much points in tie-dye method and capability of techniques. Binding technique and stitching technique on Cotton were much points in pattern design and overall image of fabric dyed. Binding technique and stitching technique on Linen were much points in 5 parts. Folding technique on Linen were much points especially in tiedye method and capability of techniques. Binding technique and stitching technique on Rayon were much suitable in 5 parts. Folding technique on Rayon were much especial points in 5 parts except overall image of fabric dyed. Comparison of three kinds of fabric and two pattern groups were that cotton linen and rayon fabrics in geometrics and naturalistic patterns had average the best in binding technique. To compare tie-dye techniques and fabrics and pattern groups had different for some parts statistically significant at level of .05

This research aimed to study the use of coarse aggregate obtained from removing old recycled asphalt pavement (RAP) in the production of the porous concrete paving block. Crushing and size separation of the coarse aggregate by using standard sieve size by selected the gradation size of the coarse aggregate that passed to sieve size 1/2” and retained on sieve size 3/8” and other that passed to sieve size 3/8” and retained on sieve size No.4 by mixing ratio 50 : 50 of the mass as replaced natural coarse aggregate. Portland cement quantity about 18% and 20% by weight of the aggregate. The water to cement ratio was 0.30 and 0.35 respectively. Compressive strength flexural strength and water permeability were investigated. The results showed that the cement content and water to cement ratio was influenced the strength properties and water permeability rate of the porous concrete paving block. The porous concrete paving block mixed with higher cement content (20%) had the compressive strength at the age of 28 days increased by 16-24% when compared with lower cement content (18%). On the other hand the water permeability rate decreased by 5.1-8.1%.

This research objective was to design the ginger candy compression machine and determine the efficiency and capacity for saving time and labor in pressing ginger candy for community enterprise groups Pim Malaherb Chiang Rai Province. Ginger candy compression machine consists of the main structure namely the extruder and power transmission systems. The machine was designed with two horsepower motors or 1.5 kilowatts to drive the shaft and to rotate the screw through the flange. This study installs the inverter to control the motor speed at 1000±10 1200±10 and 1400±10 rpm. The extrusion die had an average diameter of 9.7 millimeters. The results found that the motors speed that was suitable for compression was a Rotational speed of 1400±10 rpm. When the speed increased the efficiency and the working rate increased too. The amount of ginger stirred was used at 300 500 600 900 1000 1500 2000 and 3000 grams. The maximum efficiency was 90.85 percent. The efficiency increased with the amount of ginger stirred. The ginger candy compression machines engineering economic analysis results found that the machines operating cost was 18063.6 baht per year. When considering the machines operation at 792 hours per year the payback period was 6 months and 11 days.

The development of the application to promote active teaching in the 21st century for the lecturers of the Faculty of Science and Technology Rajamangala University of Technology Phra Nakhon. The development of the application will support the work in terms of the mobile application and web applications. This application was modified on a cloud service system. The application consideration takes into account the design of the user interface and easily use. Moreover this application can support the user via smart devices and through a web browser including access control. In the design and development of the application there are two groups of people working together group 1 Teacher and group 2 student. There is an administrator (Admin) to help manage the data within the application prototype. Based on the user satisfaction assessment of the developed application. It found that the satisfaction assessment of the application users to promote the competence of the Faculty of Science and Technology in organizing active teaching activities for skills development in the 21st century was at a good level with a total mean of 4.14 S.D. value was 0.25.

Costume fashion design thesis that reflect the character of LGBTQ from Lady Gagas inspiration aims to study the type of concept type of structure decoration technique of costume and emotional scene in the music video Born This Way by Lady Gaga in order to create the concept of costume that show the LGBTQ identity. The tools that use for study is two type of analysis which is Lady Gaga costume analysis. this part used three standard to analyze 1)concept 2)structure 3)decoration Second one is Lady Gagas costume design analysis by separated in to three part of analysis. 1)concept 2)structure 3)emotional scene aims to study the physical character and over all analysis in order to create constructively costume concept which is reflect the LGBTQ identity The results of the study showed that Lady Gagas costumes and interpretations have a distinctive feature of the distinctive layout decorative techniques and emotional scenes in the Born This Way music video emphasizing the importance and reflection of reflection. The identity of the third gender in order to be accepted by society by using the information obtained as a guideline in costume design that reflects the identity of the third gender and focuses on creating their identity and promoting the new generation in society to recognize and accept
