This research has been object to development weaving machine Equipment for weft. Design weave and Instruct technology give community. By make up weaving machine be able to ten The construct equipment for weft to tightness be equal to weft. Design weave and weave to consist Plan choose thread Heddle to tie and Move treadle. Instruct technology give community District Nong Ya Plong Amphur Wang Saphung Province Loei Which get instruct technology Make up weaving machine and design weave. Research result to invention make up weaving machine. Functional be durable Convenient to use in community. The construct equipment to thread Which consist litter move thread Bench to roll and bench to copy Functional be successful. Because of compare weft not pass process for weft at construct will cause thread tightness unequal have impact When divide weft for insert warp Divide weft unequal and Cause weft have tightness Impact when divide weft for insert warp divide weft unequal and break every. Section weft at pass process move weft thread be on as tightness unequal and will cause warp be convenient and not break. Have an effect on weave be convenient and marquisette high-quality. Design that in quantity at equal when design get efficacious change treadle be able to begin new design by not design. Instruct technology give community and community get technology and be able to design weave get efficacious. Evaluation from construct invention Design weave and instruct technology cause to know. Possibility that take research give community general and production to commercial continually

The purpose of this quasi-experimental research was to study the effect of an English camping program based on Cognitive Behavioral Theory on students self-efficacy in using the language for communication. The population of the study 118 first-year students of the faculty . of Liberal Arts Rajamangala University of Technology Phra Nakhon in the academic year 2009 were divided by using simple random sampling into 3 groups: experimental· group 1 whose members were assigned to participate in the English camping program based on Cognitive Behavioral Theory; experimental group 2 of which the members were given the infonnation on Cognitive Behavioral Theory and how to develop self-efficacy in using English for communication to read ; and the control group. The instruments used were a questionnaire a self-assessment questionnaire on self-efficacy developed by the researchers and Before & After reviews The statistics used were percentage and t-test. The results were as follows: 1. The level of self-efficacy in using English for communication after the groups participation in the English camping program based on Cognitive Behavioral Theory was significantly higher at the level of 0.05 which was not significantly different at the follow -up. 2. The self-efficacy level after participation in the English camping program was significantly higher at the level of 0.05 than that of the experimental group 2 after being assigned to read. 3. The level of self-efficacy after participation in the program was statistically higher than that of the control group at the level of 0.05. 4. The qualitative data collected from the group participating in the program indicated an improvement in the level of self-efficacy in using English for communication.

Speed Control System Design in Bicycle Robot by Low Power Method
Speed Control System Design in Bicycle Robot by Low Power Method

This paper presents compare results performance between two conventional controllers for bicycle robot. The bicycle speed control system was a highly nonlinear model multivariable and absolutely unstable. It has used for testing various design control techniques for low power. The objectives of this paper had to developed speed control which derived the mechanic model and experiment. Controllers are Proportional-Integral-Derivatives (PID) and on-off dynamic control. The dynamic system which also includes not stable friction effects the linear zed system model is used as a basis for the design to apply to speed. Computer simulation and experiment have been done controller are capable to control output speed wheel control system successfully. The results show PID controller better then on-off dynamic controller.

Studying and Product Development of Handicraft from Elephant Dung Paper for Adding Income to Community at Changwat Phra Nakhon Si Ayutthaya
Studying and Product Development of Handicraft from Elephant Dung Paper for Adding Income to Community at Changwat Phra Nakhon Si Ayutthaya

The research aimed to study and develop handicraft products from elephant dung paper for community income generation in Changwat Phra Nakhon Si Ayutthaya and to compare the product satisfaction of the target group for the original style and the new one of elephant dung paper. The target group was composed of 143 tourists from other provinces and 143 local tourists. Both target groups would like to buy handicraft products from elephant dung paper and help generate community income in Changwat Phra Nakhon Si Ayutthaya. Research tool used were questionnaire and data were analyzed by statistical percentage mean and mode. Questionnaire was used for the product attributes satisfaction evaluation of the target group including alternative evaluation process and comparison of product styles evaluation process. Data were analyzed by statistically percentage mean and t-test dependent sample. The results were as follows: 1. The target group chose the third style on 3 designs of handicraft products from elephant dung paper. 2. For the product attribute satisfaction of the target group it was found that the new style of handicraft product was more acceptable than the original one at a significance level of 0.05.

The Specific Energy Consumption of Robusta Coffee Bean Separating
The Specific Energy Consumption of Robusta Coffee Bean Separating

The aim of this research is to design and create the sorting machine within the engineering knowledge by using the three-layer sieve set cylindrical sorting machine under the various conditions of experimental. Furthermore the Specific Energy Consumption [SEC] of Robusta coffee bean separates the standard size of Robusta coffee bean the total of product separated are regarded. For the experiment condition rotation speed adjustable to 9.6 and 14.4 rpm. The raw material flow through to sieve and determination the standard size for calculating the [SEC]. The result of experiment found that the average of total of product separated was 165.1 kg/hr. and 164.7 kg/hr or 99.57% from that were passed the criteria of standard according to the ministry of agriculture cooperative. In order to the [SEC] the cylindrical sorting machine was 0.01631 MJ/kg at 14.4 rpm of rotation speed. However the values of [SEC] may be change from the effect of rotation speed of sieve set.
