Nowadays brake pad is a one of products that plays a role in the automotive parts industry and directly affects safety. Therefore there are many designs of brake pad for product development. The technique of reinforcing the layer in brake pads is another option for developing such products. The objectives of this research are to solve the problem of noise from brake pads using the material layer reinforcement technique and raise the quality of brake pads to use in the industrial sector. As a result the prototype brake pads with reinforcement techniques by means of damping layer were performed. Consequently the experimental work reveals that the brake pads with damping layer technique for brake pads can reduce vibration and also brake noise at the same frequency at less 10 percent at braking speeds of 50 100 and 130 km/h. Besides this technique can be applied to the production of brake pads in the same formula. However the prototype brake pads is still in the product development phase for testing in a variety of conditions both temperature factors and usage period

Defrosting at evaporator panel is one of working cycles in freezer. Power consumption in defrosting does not meet the objective of using freezer therefore the approach to decrease power consumption in defrosting is one strategy for energy saving. Normally the cycle of defrosting in freezer is a constant time that specify by referring to the highest humidity period. With this control concept the problem of temperature exchange is not occurred from ice accumulation at evaporator panel but it makes the over necessity of defrosting process in the low humidity season and cause the unnecessary power usage in freezer. This research presents the control approach for defrosting by using the difference of the temperature at evaporator and the temperature at chilling area. By using this approach the defrosting process is operated depend on load and the fan is on or off relate to defrosting time. Test results demonstrate that about 12% of power can be saved by this control approach when compared to constant time control.

Sweet tamarind is a unique and economic plant of Phetchaboon province and it has already been geographical indication (GI) registered. One of its main problems is fungal degeneration which cannot be physically visible. This causes the consumer’s uncertainty on its quality especially sweet tamarind from small communities. This led to the study on the use of household heat to reduce fungal degeneration by steaming at 100oC for 50 60 70 and 80 minutes and drying in the hot air oven at 70oC for 3 hours. It was found that increasing the heat resulted in darkening the sweet tamarind color and heightening up its content moisture (p<0.05) statistical significance. Drying temperature at 60 70 and 80oC revealed the higher the heat the shorter the drying time and the sweet tamarind content was darker. In addition drying significantly decreased the moisture and preference score of sweet tamarind (p<0.05). The storage of sweet tamarind in mesh bag at ambient temperature revealed that the increase of the storage time resulted in a significant increase in the moisture of the sweet tamarind shell (p<0.05) and could preserve the tamarind for at least 12 weeks without the deterioration from the fungus.

The purposes of this research were to study the education model and express the guidelines of education management of work-integrated learning (WiL) for tourism industry model. The research method was used by quantitative approach and qualitative approach by studying relevant approaches and theories including the synthesis of documents and researches. Data were collected by questionnaires in-depth interview and group discussion with target persons who are from academic institution business sectors and organization profession of tourism industry. The research findings showed as follows. First the highest level of learners’ work experience benefits and challenge of work-integrated learning (WiL) is to prepare the learners for work in the future. Secondly the key success factor of education management of work-integrated learning for tourism industry is to establish in education cooperation among academic institution business sectors and organization profession of tourism industry. In the part of the essence of educational cooperation is to develop the curriculum program together by providing the opportunity for learners to practice and work in business sectors in accordance with the authentic learning method and the authentic assessment as well. Moreover there should be sharing the experiential learning among instructors learners and experts from business sectors and organization profession of tourism industry to develop the appropriate and modern education management of work-integrated learning (WiL) for tourism industry model.

This research aims to study Design guidelines for home decoration woven from pandanus odoratissimus linn the woven pandanus Phanans home parish of the island of Koh Lanta Krabi. Sample in Research is foreign tourists 50 peoples and Local 50 peoples. Want to buy product Home decoration Krabi. The research instrument was a questionnaire want side different of the target audience have confidence equal to .890 statistical analysis was performed by percentage. Average mode and questionnaire to evaluate satisfaction in the field of use and in marketing for home decoration woven from pandanus in the process of evaluating alternatives and in the assessment process compare with the original souvenirs by questionnaire 2 edition have confidence equal to .893 and .830 respectively. Statistical analysis was performed by means of percentage mean and test the hypothesis with the t-test statistic type Dependent Sample. The research concludes that. 1. Workings portfolio design home decoration method 1 small put of box can adjust the size between channels. Method 2 box put of large removable foldable and Method 3 small table of lamp removable foldable. 2. Target groups choose the design of home decor in the 3 approach. 3. The target audience is satisfied with the new home decor more than the original in all sides. Statistically significant at the .05 level dealers are more satisfied than the original model in almost every aspect. Except for eco-friendly images and the new home decor is more effective than the old one.
