การผลิตแผ่นฝ้าเพดาน T-Bar ทำจากส่วนโคนของลำต้นสบู่ดำ

The objective of this research is to produce the T- BAR plate from the agriculture process’s waste. The researcher brought physic nut plant to produce T- BAR plate forint prior building. It was tested based on Thailand industrial standard (TIS 876-2547)which are Determination of moisture content density absorption and expansion when soak in water .For cohesion and perpendicular surface tension and tested for flexural resistance and modulus of elasticity The results show that suitable size material should not thicker than 2 centimeters. The experiment of ratio between physic nut plant and phenol cyanide resin at 90:10 and 92:8. The researcher found that suitable proportion are 92%physic nut pant with 8%phenol cyanide resin. The temperature used for compression was 120 C. The appropriate density to the compression plate was 0.80 g/cm.3 The moisture content of materials before compression was at 8.89% average. The suitable compression was 150 lb/in². The moisture content was at 7.65% The density is at 0.818 g/cm.3expansion value when soaked in water for 2 hours was at 8.02% water absorption retain 2 hour is at 14.23% Inner bond is at 0.56 MPa. Flexibility is at 21.45 MPa. mordulus 2116MPa.Which the result of tested with the Thailand industrial standard (TIS 876-2547).The experiment concluded that we can used physic nut plant as material to make T- BAR plate for interior building.

Image enhancement is one of using in various digital signal processing areas. Advances in microcontrollers DSP boards and computers have been developed traditional algorithms to improve the quality of the resulting image. This paper aims to present the contrast enhancement using weighted bi-histogram equalisation. In additional this technique must use two weighted factors which is calculated by the histogram distribution ratio. Likewise an original image will be equalised by the modification of the probability density function of the gray levels. As the experimental results the contrasts of resulting images are improved for robot vision implement and human perception including absolute mean brightness error (AMBE) limitation.

This research aims to develop a web-based instruction (WBI) applied in the computer technology course. The proposed WBI composed of the following components: lessons of the computer technology course pre-test and post-test exam: determining the effectiveness of the proposed work and user satisfaction questionnaires. It is also evaluated a study achievement and a usage satisfaction by using efficiency and effectiveness test of lessons and satisfaction test of users. In this work users are the second year students in major of Computer Technology Faculty of Science and Technology Rajamangala University of Technology PhraNakhon for 30 students. For experiments the results show that its efficiency is 80.13/83.67 which are met the standard criterion 80/80. In addition the study achievement scores of students who studied the proposed WBI are also higher than students who studied with ordinary courses at the statistical significant level 0.05. Furthermore an average of students’ satisfactions score is 4.20 which determines students satisfy with the proposed WBI at a high-level. Finally it can be concluded that the proposed WBI is effective.

Development of local product made from Pahkanmah based on integration of local wisdom and principle of fashion design to promote community career : A case study of Wanon-nivat district Sakon-Nakron province. The aim are Promoted the concept of product development from Pahkanmah development a model of clothing from Pahkanmah based on integration of local wisdom and principle of fashion design and knowledge transfer development of clothing from Pahkanmah to Community of Wanon-nivat district Sakon-Nakron province. There were tree issue 1. Making Knowledge in products development from Pahkanmah to guide the creative product of the community. 2. The communicate knowledge in product creation to community and standardize the product including the addition the target group. 3. Promotes the Innovation of Product design commercial creation create of community identity for potential development and sustainable occupation. Data were analyzed using a descriptive analysis on the concept of local wisdom from a weaving bee Pahkanmah Wanon-nivat District Sakon-Nakron Province with concept of fashion design and analyzed manner statistics data of the questionnaire about the requirement and the contentment that have to build clothes format from Pahkanmah of location in woman working age between 25 year - 35 year the residence is in Bangkok and the perimeter 200 persons amounts for take the data has that to go to apply in designing and produce clothes from Pahkanmah. The results showed that local wisdom from Pahkanmah Wanon-nivat district Sakon-Nakron province have transmitted passed on from generation to generation from production to household appliances then have design and color follow the inventory obtained from the local when bring the products a clothing design then has to use the patchwork technique and applied placement pattern of Pahkanmah the results forms and patterns interesting and appropriate with trend fashions. The community groups to gain knowledge and can use wisdom from Pahkanmah and fashion design idea the inventive uniform for woman to promote community career.

Relationship of perception, attitude and participation in 3D policy-based activities of students in Rajamangala University of Technology Phra Nakhon (RMUTP)
Relationship of perception, attitude and participation in 3D policy-based activities of students in Rajamangala University of Technology Phra Nakhon (RMUTP)

The purposes of this study were 1) to study information perception attitude and behavior of undergraduate students for participation in 3D-based activities at Rajamangala University of Technology Phra Nakhon; 2) to compare personal factor and participatory behavior in 3D-based activities; and 3) to study how information perception and attitude correlate with participatory behavior in 3D-based activities which include Decency Democracy and Drug-free. Data were collected from 400 RMUTP undergraduate students from all nine faculties in 2010. Results of the study indicated that RMUTP students perceived news releases on 3D policy at average level. Similarly their overall attitude towards 3D policy campaign was also rated in average level. Hypothesis testing results showed that firstly students with different gender and faculty of showed significant different participatory behavior in 3D-based activities at the level of .05. Secondly the perception of 3D policy new releases had positive correlation with participatory behavior in 3D- based activities. Thirdly attitude towards 3D policy of the university had positive correlation with participatory behavior in 3D-based activities.
