This study was aimed to explore the needs for vocational art crafts training needs for the senior association in Karnchanaburi. The questionnaire with the reliability of 0.88. was used to explore the needs for the art crafts training for the career development. The samples were 30 people in the senior association in Karnchanaburi. The results showed that most of the samples were 61-71 years old and most had the primary education followed by secondary education. Their former occupations were business owners who were married and some were married and had congenital disorder. It was found that most of the participants wanted to be trained to fold towels into the shape of animals followed by scrap fabric rugs. As for the training period throughout the course most participants required 2-3 day trainings from Monday to Friday 08:00 to 16:00 in order to make money. The second to that was to practice meditation and the third was to use the knowledge acquired in everyday life.

Nowadays Eye tracking technology is the next challenges of human computer interaction (HCI). This technology can help people all over the worldaccess computers through systems that use gaze control and especially important for people with physical disability. This research presents a system of assistive technology base on an eye-tracking interface while supported the communication system for independent living of persons with disabilities usability. The primary method of this system consists of a selection of pictogram buttons on three websites which used a low-cost eye-tracking device. The evaluation used the throughput of standards for computer pointing devices as a measurement of user performance to look at an on-screen target and dwell on it for 500ms for selection. The results showed that ten participants with a disability can be pointing and selection their overall mean throughput was 1.08 bits/s. Moreover the overall users of respondents were rather satisfied with the system. Consequently eye tracking technology is a great tool for interaction in the web application for a user with a disability.

The performance investigations of subcritical ORC supercritical ORC and trilateral Rankine cycle (TLC) power plants with the heat source temperatures of 210-250°C were conducted and compared in this study. Several working fluids were evaluated. A MATLAB code was developed and used in this study. The thermodynamic properties of the working fluids were calculated by using NIST REFPROP program. The justification of the code was validated with a result taken from the literature. The optimal operating conditions were searched using the golden-section technique. The maximum net output power of 141.72 kW was obtained when using the supercritical ORC plant with R141b as its working fluid and the heat source temperature was at 250°C. The corresponding cycle efficiency was 16.25%. When using the subcritical plant at the same heat source temperature the maximum net output power of 133.40 kW and cycle efficiency of 15.70% are obtained when pentane is used as the working fluid. Furthermore the net output power of 133.82 kW and cycle efficiency of 14.90% are obtained when using R141b as the working fluid in the TLC power plant. According to the off-design simulations an appropriate adjustment of the working fluid flow rate can mitigate the variation of the net output power.

Research on the development of souvenir products from research and development of scientific research applications using scientific research methods Create a blog as a tool. Ask experts in the development of souvenir products that are suitable for weddings. 3 types. Most experts choose the format. Contemporary styles and modern forms of invention with a pattern that is not ancient and not too advanced. The colors of contemporary styles are adjusted with modern styles. Cost reduction in the production of souvenirs Then comparing the efficiency of the odor release between perlite stone scent decoration and postmodern. Based on gas chromatography-mass spectometry (GC-MS) technique it was found that the release of the aroma of perlite coated with non-coated peril stone film And postmodern in various time periods that are measured by% peak area Compared by setting it in the open system Saw that the amount of substance decreased with time The coated perlite stone keeps the smell well after 23 days more than the coated perlite stone. And the bushes that have released the fragrance for a minimum of 11 days Then study the satisfaction of the target group on the development of the perlite stone by the scent decoration. By dividing the 4 aspects of the study namely the product side it was found that most respondents had the highest level of satisfaction (4.60) in terms of materials. Most respondents were satisfied at the highest level (4.70). The respondents were satisfied at a high level (4.39) and the value of the respondents were mostly satisfied at a high level (4.15).

This continued 2nd year researchaims to study the development of the para rubber press machine with wrought pattern for continued 2nd-year. Used natural para rubber mixed in a Ta-kuong by normally practical para rubber farmer style to evaluate the rubber press machine. A machine consists of the 11 roller sets in vertical pathway with press sticks on top. The components are as follows: a water press roller with a slope surface to reduce the diameter around 1-1.5 mm from a center the 3-pair sets of normal press rollers and the 2 duo sets of wrought pattern rubber press rollers with the induction motor at 1430 rpm. The rotating transmission based on belts and chains with a . The evaluated results produced the dried para rubber sheets thickness at 3.79 mm on average as the 2nd rubber sheet type standardin marketing need. From a top tray a farmer can put a sticky para rubber piece to a roller press machine easier than normal just 5.9 second on average with lower hand power to handler of the rubber pieces. In finally the wrought patternrubber sheets by a worker to carry the ta-kuong to a top tray of a rubber press machine and a rubber press man to put the para rubber pieces to a machine thus the completed 186 wrought rubber sheets per hour on average.
