การพัฒนาระบบการสื่อสารเพื่อการดำรงชีวิตอิสระของผู้พิการ
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.
การปั่นเส้นด้ายจากเส้นใยผลตาลสุก ด้วยกระบวนการปั่นด้ายแกนกลาง
The research aims to investigate on the yarn spinning production using processed Borassus fruit fibres bleached and soaked in water before arranging into fibres of proper size in preparation for the yarn spinning from Borassus fruit fibres using handspun core-spinning technique. The study found that yarns produced by such method are uneven with loose and tight twists and multiple knots along the threads. Furthermore Borassus fruit yarns have rough and coarse texture. Scientifically tested the properties of the yarns indicate that the highest yarn count of this Borassus fruit yarns is at 665.00 Tex while the lowest is at 383.33 Tex. Its tensile strength counts at the maximum level of 24.33 Newton with the elongation level of 21.90 Newton. The average tenacity comparing with yarn count is 0.04 Newton/Tex. The produced yarns consist of blending Borassus fruit fibres and Polyester at the proportion of 83: 18. After the spinning process Borassus fruit yarns are developed into textile weaving together using cotton as warp and Borassus fruit fibres as weft. The finished product was analysed showing that the warp and weft’s tension strength are at 581 Newton and 595 Newton respectively while the tenacity are at 65.05 Newton and 78.95 Newton in consecutive order. The blending proportion of woven textile is 49:45:6 of cotton Borassus fruit fibres and Polyester accordingly. Hence the study shows that the production of Borassus yarns is promisingly producible and the woven textile from such yarns could be used for further product development such as household textile.
ปัจจัยที่ส่งผลกระทบต่อการขอกำหนดตำแหน่งทางวิชาการ ของบุคลากรสายวิชาการ คณะวิทยาศาสตร์และเทคโนโลยี มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร
The objective of this research is to study the factors affecting the academic position of faculty members of the faculty of science and technology Rajamangala University of Technology Phra Nakhon which consists of 5 divisions; Division of Environmental Science and Technology Division of Industrial Materials Science Division of Computer Science Division of Science and Division of Mathematics and Statistics. By using SWOT Analysis tools it is found that the main strengths are the progress in the professions increasing of the development of their knowledge potential and fame. The main weakness is the lack of understanding of how to write teaching documents lack of time and lack of interesting research topics. An opportunity is the mandatory criteria of the university. The faculty has financial support for academic positions and other rights from academic positions. The threat is the lack of research budget. The faculty does not have specialized counseling officers and frequently change the assessment criteria. We use the results of the SWOT analysis to group relationships with the TOWS Metrix tool analyzed in the form of a matrix relationship to define different types of strategies to suggest the results of the study in formulating policies to help support and encourage faculty members of the faculty that can further be determined for academic.
การต่อลงดินของระบบไฟฟ้าเพื่อลดผลกระทบของแรงดันไฟฟ้าตกชั่วครู่ที่เกิดจากการลัดวงจรแบบหนึ่งเฟสลงดิน
The faults in a power distribution system do not only impact to power outage directly. They also cause voltage sag problem spread over the system. A single-line to ground fault is about 70% of the overhead system faults. The magnitude and duration of voltage sag causes the economic damage of the system. This paper presents an analysis of the different systems grounding to mitigate the voltage sag in a power distribution system by using the technical analysis system in case of one phase to ground fault. The objective is to minimize voltage drop for users using the simulation with single line to ground fault in distribution system voltage level at 22 kV PEA’s test system by the computer program. The results show that the grounding method can mitigate the voltage sag and reduce the damage of the economic system.
การพัฒนาหลักสูตรฝึกอบรมวิชาชีพระยะสั้นด้านคหกรรมศาสตร์ ของสมาชิกชมรมผู้สูงอายุบ้านโพธิ์แจ้ ตำบลบางน้ำจืด
The present research has the following objectives: 1) To examine the needs for short course training in home economics 2) To develop the short course curriculum in Home Economics in accordance to the needs of the members of Baan Pho Jaa Elderly Club and 3) To examine the satisfaction of the training in Home Economics for the members of Baan Pho Jaa Elderly Club Bang Namjuerd Muang District of Samutsakhorn Province. The samples selected for the research are the total number of 30 members of Baan Pho Jaa Elderly Club Bang Namjuerd Muang District of Samutsakhorn Province who have shown their interest in the program as well as had the capability to be trained. The research instrument is a questionnaire developed by the researcher and a training curriculum for the short course training in Home Economics. The data are analyzed in frequency and percentage. The findings are as follows: The members of Baan Pho Jaa Elderly Club showed the need to be trained in Home Economics with crispy rice noodle with spices tapioca dumpling with shiitake and salted duck egg with herbs respectively (43.33% 23.33% and 16.67%). The research developed the training curriculum accordingly using Taba’s instruction of curriculum development as consisting of 4 modules: i) an introduction to cooking ii) basic ingredients culinary instruments and cooking techniques iv) making crispy rice noodle with spices and v) package designing and calculating selling prices. The six-hour session of training took place at Baan Pho Jaa Medical Centre on Saturday – Sunday at 09.00 – 12.00 hrs and 13.00 – 16.00 hrs. The results of the training are as follows: i) the trainees showed an overall working skill at a good level ( X = 2.70) ii) the outcomes were evaluated and fell at a good level ( X = 2.83) and iii) the satisfaction of the trainees was considerably good ( X = 3.99).
