This applied research want to study the factors affecting the student‘ learning achievement instudying Data Structure and Algorithm. The samples were selected by stratified random sampling 93 students from 121 students who studied in semester 2/2009 by using questionnaire. The statistics used were descriptive statisticst-testOne way ANOVAPearson correlation and multiple regression at the significance level of 0.05. The findings revealed that the mean of grade point average was 2.69 their average midterm scores were 22.47 out of 35. The successful were grade point averagefair expectation of knowledgeand future application.The factors affecting student’s achievementwere basic knowledge of programmingmidterm scores studied resource and facilities. In addition the 2 year programme’ average midterm scores were higher than the 4 year programme ranging from 1.11 to 5.34 at the significance level of 0.05. The forecasting equation for learning achievement is

This research had objectives for the purpose of studied the rice production technology and cost benefit of farmer members in community rice seed centers (CRSC). The research case study was conducted in Phatthalung province by field surveys combining participatory rural appraisal and structured interview of 35 members during the research period from April 2012-August 2012. The CRSC received contribution grain from government service. The result showed that majority rice community center member were men and in one family had average 2 workers. Their ages between 51-60 years old. The Majority of education were primary school (grade 4). The cultivated area of rice between 11-20 rais. Rice production can generally be divided into the following 10 stages that is soil improvement land preparation crop establishment plantation water management nutrient management pet control weed control harvesting and post harvest. The results of the study found that almost all farmer using private land (69.72 %). The important expense was variable cost 80.25 % Ban-Phab is 3509 bath per rais. Average benefit per rais is 6985.04 bath per rais. The rice break- event point is 317.56 kg per rai. However return on investment explore CRSC Ban-Phab is 99.06 %

The objectives of this study were to develop the paddy washing machine for community rice milling machines to extend this technology to rural community and introduce to commercial production. The experiments were conducted at the Department of Agricultural Engineering and Technology Faculty of Agriculture and Natural Resource Rajamangala University of Technology Tawan-ok Bangpra Campus Sriracha Chonburi. The results showed that paddy washing machine was suitable for high moisture content paddy between 20-25 % and washing for 1-3 minutes demonstrated better milling quality than unwashed paddy. Performance test of this developed paddy washing machine using drum speed at 35 rpm drum slopes of 1 2 and 3 degree and 21.60 % MC KDML 105 paddy could reach capacity about 150-200 kg/hr. The milling quality was significantly different at 95% confidence level from unwashed paddy. Furthermore this machine provided 1% better in purity and 11% better head rice yield at the same milling degree. From the study it can be concluded that increasing drum slope gave higher capacity higher power efficiency and lower water usage. The best condition was working with drum slope of 3 degree. The paddy washing process gave higher purity of paddy head yield and power efficiency of washing process while the color property was not significantly different from unwashed paddy at the same milling degree.

This study evaluated the genetic diversity of two natural populations of Neolissochilus stracheyi in Nan River watershed Amphoe Bokluea (BK) and Amphoe Mae Jarim (MJ). We analyzed microsatellite markers originally developed for Tor tambroides (Nguten et al. 2009). Three out of five microsatellite loci analyzed were polymorphic . Genetic variation within BK and MJ populations were not different. The number of allele per locus and allelic richness averaged over three loci was 2.33 and 2.67 for BK and MJ respectively. Observed heterozygosity value was 0.50 and 0.56 and the average expected heterozygosity was 0.41 and 0.53 for BK and MJ respectively. In addition the two populations were genetically distinct (P<0.05) and geographic isolation of two locations may explain this genetic pattern.

This research was a study of energy management in public building. The goals of this project are to decrease energy consumption and to enhance energy management system of the building. Regarding the energy survey the building lights are turned on for 24 hr. per day in order to satisfactorily serve the customers. In the study it was found that the energy consumption of electric light on the fourth floor roof can be reduced by changing the light “Floodlight MH. 4x250W” to be “High bay LED 4x150W” For the merit this project can save the energy around 6632570 baht per year and switching towards high-efficiency lanterns and replacing FL. T8 light bulbs installed in the walkways with FL. T5 models. This reduces lighting cost by 361425 baht per year. Moreover the energy management system was analyzed by using SWOT Analysis. As a result we observed the barriers to communication must be overcome to promote energy conservation. One approach is to increase the performance through the use of communication strategies within organizations. This method will help align employees understanding and participating in activities of conserve energy.
