Nowadays the automotive industry in Thailand has been widely growing. Brake pad is one of the automotive products that play a vital role in automotive industry because it is the most critical seeurity part. Consequently testing products for quality are extremely requested. However the precise equipment and function tests which show the real effects are not available enough and cost a lot. Therefore they cannot response to the deman in the automotive industry development. In this study the frictional test jigs for friction measurement JIS K7125 [5] and the clutch facings for automobiles JIS D4311 [6]. A study of the frictional test emphasizes on the static friction (μs) and kinetic friction (μk) in different condition. There are 3 specimens of brake pad supposted by the industry company. These specimens were tested and the results from the pin-ondisk and those from the friction testing were compared. The results revealed the correspondence of the two-sided results but the pin-on-disk’s friction coefficient is more than the friction testing’s friction coefficient by 19.56%. Moreover the coefficient of friction varies according to the temperature Besides the static friction (μs) is likely more than kinetic friction (μk) and tends to differ considerably under high pressure condition.

The objectives of this study is to 1) study the behaviors of consumption of baked goods in Bangkhen district Bangkok and 2) study factors of decision making of consumers on services. We have sample of 400 subjects and used statistical methods consist of frequency proportion mean standard deviation t-test and F-test. From the results we found that most of the consumers are female of age between 20 – 30. Most of our samples are students and have income less than 10000 baht per month. For the results on behaviors we found that most purchases are for self-consumption. Cakes are the most popular baked goods. There’re 1 – 3 quantity of goods per purchase and cost around 70 -150 baht. The frequency that samples go to bakery is 1 – 4 times a week from Monday to Friday and around 15.01 – 19.00. Samples mostly got information of bakery from personal communication. The results show that price is the most important factors influence on consideration of consumers given ( = 4.46) of mean. While other important factors are products ( = 4.37) convenience ( = 4.10) brand loyalism ( = 4.05) commercial ( = 3.99) brand’s quality ( = 3.96) and brand ( = 3.85). There’s no difference on the influence of gender on consumption but there’s a significant difference between price and brand’s quality and between ages and between convenience and commercial.

This research aims to experiment with natural dye from the longan leaves Color fastness UV protection Designed textile products from Textile dyeing of longan leaves. and to teach the dye from longan leaves for design and processing of textile products to the community under the concept of the creative economy. The study consisted of two parts The first part is Color fastness and UV protection from fabric dye from longan leaves. The second part is Designed textile products from Textile dyeing of longan leaves. The research area at Yu Wa San Pa Tong district Chiang Mai province area planted with longan. This research is part of the solution to the problem of waste longan leaves. In addition farmers have to produce compost leaves and fruits are often destroyed by the fire. Impact on air pollution and Haze occurred in Chiang Mai now. Natural dye extracted from longan leaves was applied to a silk fabric by exhaustion dyeing process. Aluminium potassium sulfate ferrous sulfate copper sulfate and stannous chloride were used as mordants. The dyeing was conducted with and without metallic salt mordants using three different mordanting methods pre-mordanting meta-mordanting and post-mordanting. The colour of each dyed material was investigated in term of the CIELAB (L* a* and b*) and K/S value. The color fastness to washing rubbing perspiration light and water of the dyed samples was determined according to ISO test method. The results show that the optimal results were achieved when dyeing at 80 ?C for 50 minutes and at pH 3. Silk fabric dyed in a solution composed of a Longan from leaves without mordant showed a shade of pale yellowish-brown while those mordanted with stannous chloride alum and copper sulfate produced a variety of medium to dark yellowish-brown color shades. However duller and darker brown shade was obtained with ferrous sulfate mordant. The color fastness to washing water perspiration and rubbing were good to very good. However the light fastness results showed fair level except fabric without mordanted whose colour change rating was poor. The results confirmed that natural dyes from longan leaves extract with metal mordants have potential applications in fabric dyeing and in producing very good UV-protective silk fabrics. The second part is research data collected from literature research related research and field data was collected by interviewing recording a career field research brainstorming sessions and participatory action research between the villagers to researchers. The findings presented by descriptive analysis. The result is Textile product design of longan leaves dyed fabrics must take into account the capacity of the group. The villagers have restrictions on the production of textile products. There is no potential for forming other products. In addition to the garment as well as the group was started. The natural dyes of the longan leaves is new knowledge for the group. Therefore textile products in the early to conclude that the textile products the group members have expertise in manufacturing mens casual shirts ladies casual shirts and scarf. Create patterns with a variety of tie-dye technique. The silk material used as the main material used is cotton minority. Users is a group of conservative tastes nature lovers and those with artistic taste. The procession design and production-oriented textile products are Green Design

This study was aimed at studying factors affecting secondary students decision making to attend tutorial schools in Muang District Nonthaburi. 400 samples from 5 schools were selected. Data collection began in 2016 and were analyzed by logistic regression analysis The results revealed that most students chose to participate in tutorial classes The factors affecting decision making were family incomes as well as the course to study at the significance level of 0.05 It was also found in the research that the Marketing Mix and social factors did not influence the decision making to attend tutorial schools at a significant level of 0.05

Bags product design from Na Muen Si woven Na Yong District Trang Province which is special project that objective is to study pattern of Na Muen Si woven to bags product design from Na Muen Si woven Na Yong Trang province and study about customer satisfaction this work devide by into 5 step about customer satisfaction and analyze information of student groups Faculty of architecture and design Rajamangala University of technology Phra Nakhon between 20-25 years old from 120 consumer Data were analyzed using percentages and averages. The result of study most consumers are female 62.50% bachelor’s degree 3rd years 29.17% with income 10001-15000 bath per month 52.50% The result satisfied for bags product from Na Muen Si woven Na Yong District Trang Province. It found that most consumers satisfaction was high an average total of 4.21 and when considering the appropriateness of the bag with patterned of Na Muen Si woven found that most consumers are satisfied with the briefcase Bueng Bua pattern.
