The purposes of this research were: 1) to study the effectiveness of customer relationship management influence the customer trust on service quality on private vehicle inspection service in Phra Nakorn Si Ayutthaya 2) to study the customer loyalty influence the customer trust on service quality on private vehicle inspection service in Phra Nakorn Si Ayutthaya. 3) to study the effectiveness of customer relationship management influence the customer loyalty on private vehicle inspection service in Phra Nakorn Si Ayutthaya. The samples in this study were 325 Banpan private vehicle inspection service’s customers in Sena district Phra Nakorn Si Ayutthaya province. The data were analyzed by using frequency percentage mean standard deviation and Multiple Regression Analysis. The results found that the opinion levels on effectiveness of customer relationship management in overall and each aspect was found that the customer engagement customer hearing customer suggestion customer retention and customer prospecting were at the high level. The opinions level toward the customer trust on service quality was found at highest level in overall. The opinions level toward the customer loyalty was found at high level in overall. The result of hypothesis test found that the effectiveness of customer relationship management in customer suggestion customer retention and customer prospecting were influenced the customer trust on service quality. However the customer engagement and customer hearing were not influenced the customer trust on service quality. The customer trust on service quality were influenced the customer loyalty. The effectiveness of customer relationship management in customer engagement customer suggestion customer retention and customer prospecting were influenced the customer loyalty however the customer hearing were not influenced the customer loyalty.

This research report is manipulated that summarized the moment of research project in the subject of “The optimal image processing for paddy studies: Variety classification and rice kernel damage inspection”. This project had been take time in 12 mounts. We focused on rice variety classification and rice kernel damage inspection. We also investigated the apparent friction of rice surface. Results showed that area and size were the quantities that have the potential to classify rice variety and also rice kernel damage inspection. In addition we also found that geometric mean diameter performed characteristic to apparent friction of rice surface in kerosene. These results have the potential to be the basis information in terms of developing instrument for quality control and variety classification of cereal.

The results revealed that the manager๛s opinions towards operation of quality control and inspection of auto-parts at a high level were lineworkers in car accessory production plant and other production plant. The opinions of the office workers towards operation of quality control and inspection of auto parts at a high level were lineworkers in car body production plant car accessory production plant and other production plant. When comparing the operation level of quality control and inspection of plants classified by types of vendors it was found that there was a significant difference at .05 level. The collected data were analyzed by SPSS program into percentage mean standard deviation t-test one-way ANOVA and multiple comparison.

Brake system is used the friction between disk and pads. In the driving conditions the brake behavior from the driver is difference. Based on this reason the damage on disk and pads are occurring. Nowadays the ratio of compound materials in pads is several and involved automotive industry has not available enough to experiment. Thus it is difficult to brake pads damaged analyzing in several driving conditions. In this problem the mechanical property tester is main tool for experimenting. And test procedure based on the Brake lining and disc brake pads compressibility JIS D 4413 [7]. The experiment emphasizes on the flexibility behavior and internal energy by volume with 3 types of brake lining and pads. For the experiment focused on conditions by normal apply brake repeat apply brake and suddenly apply brake. The results revealed the normal apply brake condition the maximum and minimum of flexibility behavior was appeared on brake lining and pads type A and type C with testing temperature at 2000C. By the repeat and suddenly apply brake conditions the brake lining and pads type C and type A with 300C is given to the maximum and minimum flexibility behavior. In case of internal energy by volume the maximum and minimum energy was appeared on pads type C and B at the 300C of testing temperature. For the testing temperature at 200 and 4000C the pads type A and type B were got the maximum and minimum energy respectively. On the other hand at the high flexibility behavior is given to high internal energy at the high temperature of the apply brake condition.
