การพัฒนาเครื่องมือวัดค่าความเร่งเนื่องจากแรงโน้มถ่วงของโลก
On Earth all objects have a weight which Earths mass exerts on them to downward force of gravity. The weight of an object can find somethings weights in Newton unite. It calculated on multiply the mass in kilograms by the acceleration of gravity in the units of meters/seconds2. The purpose of this study was to design and develop an experimental setup for measuring the gravity acceleration. It involved designing by using free-fall motion method in vacuum tube based on digital Technology and photo gate sensor measured the velocity of the ball object. The data were analyzed by Microsoft Excel. The value of gravity acceleration obtained at 9.617 m/s2 from the experiment set up. The value from the experiment was compared with the obtained from true value at Bangkok Thailand. It found the error at 1.697 %. The assessment of the quality used a questionnaire for data collection. Five content experts in Physics teaching evaluated it. That found mean 4.89. The results of the study revealed that the experimental set up were excellent quality of and high efficiency. So that this experiment suitable to be used in physics classroom.

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.

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.

The purposes of this research were 1.) to study of expectation and reality for Development of research on Academic Staffs of RMUTP 2.) to study of needs assessment for Development of research on Academic Staffs of RMUTP. The sample is Academic Staffs of RMUTP from 9 faculty 343 Academic Staffs. The data were analyzed through percentage (%) mean (x̄) standard deviation (S.D) t-test modified priority needs index: PNI modified and content analysis.The results demonstrated that : Current conditions and expectations regarding the development and research of academic staff found current weather conditions are on average lower than expected nearly all sides. Considering the sort of requirements necessary for the development of research staff academic overview. The PNIModified between 0.04 -0.22 and found to have the highest PNIModified is The development of self-education and self-improvement with training / seminars (0.22) for a final order management (0.04).
