เครื่องทดสอบพฤติกรรมวัสดุความเสียดทาน
Nowadays the Thailand automotive industry widely grows. Brakepad is one of the automotive productions that role to automotive industry because it is the most critical security parts. Consequently testing products for quality are extremely requested. However the equipment and function tests are not enough and are also high cost so it cannot supports to the automotive industry development. In this work the initiation and design of frictional test were carried out. The testing procedure is referred to The special test jigs for friction measurements JIS K7125[5] and Clutch facings for automobiles JIS D4311[6].A study of the frictional test emphasize on the static friction(l-ls) and kinetic friction(l-lk) in different condition. There are 3 specimens of brake pad supported by the industry company. These specimens were test and compared between the pin on disks result and the friction testings result. The two-sided results from the analysis correspond but the pin on disks friction coefficient is more than the friction testings friction coefficient by 19.56%. Moreover the coefficient of friction tends to follow the temperature. Besides the static friction(l-ls) is likely more than kinetic friction(l-lk) and will be high difference in high pressure condition.
การพัฒนาลวดลายพิมพ์จากศิลปะอาร์ตนูโวบผ้าใยกัญชง เพื่อออกแบบชุดทำงานสตรี
The objectives of this research are 1) to develop the printing pattern from Art Nouveau on hemp fabric by way of screen printing 2) to design the womanfs working attires by using hemp fabrics for printing the pattern from Art Nouveau 3) to study the satisfactions of samples who are women in working age in Bangkok Metropolitan area: Sat horn and Bangkok toward the womanfs working attires with Art Nouveau pattern printed on hemp fabrics. The sampling group is women in working age ranging from 25 to 35 years in Sat horn and Bangruk Areas Bangkok Metropolis in number of 384 persons. Instruments used are Questionnaires and womanfs working attire prototype in number of 9 models. Data analysis statistics are percentage mean and standard deviation. Actions are carried out by studying the concept of Art Nouveau in order to design the printing patterns in 3 designs consisting of butterfly design flower design and creeper design for screening on hemp fabrics and tailoring them into womanfs working attires in the style of dress jacket and skirt of 9 models.

The objectives of this research are ; 1) To study the dietary behavior of patients with Non-Insulin Dependent Diabetic Mellitus (NIDDM) DonToom Hospital NakornPathom Province; 2) To study the environmental factors on knowledge about nutrition and health self care of patients with NIDDM; 3) To study the relationship between dietary behavior and environmental factors nutritional knowledge and self care factors of patients with NIDDM. Questionnaires were used to collect data Data analysis using the number percentage mean standard deviation and Pearson Correlation (r). The results showed that the majority are female between 56-60 years of age married highest education level: completed primary school agricultural occupation monthly income was 5001-10000 Bahts and the majority lived with husband wife and children. The overall environmental factor affected dietary behavior of patients with diabetes at a high level. The nutritional factor affected dietary behavior of patients with diabetes at the highest level. The self care factor affected their dietary behavior at a moderate level. Study of relationship between dietary behavior personal and environmental factor nutritional factor. and self-care factor have relationship at the statistical significance of 0.05.
