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

As the high performance electronic devices are required the better heat dissipation in electronic packaging is necessary. In this work the thermal diffusivity of epoxy-based adhesive used as an underfill material in electronic packaging can be improved by adding nano-sized inorganic fillers. These fillers including aluminum oxide (Al2O3) silicon nitride (Si3N4) and silicon carbide (SiC) were used alone for preparing particulate filled-epoxy adhesive. Furthermore In order to achieve good dispersion of filler in matrix the adhesive’s preparation process was adjusted. The maximum loading of fillers in adhesive were determined by the homogeneity of filler and matrix. In addition to avoid the agglomeration of filler silane coupling agent was treated onto surface of aluminum oxide filler to improve interfacial interaction between filler and epoxy resin. The effects of the filler type and filler’s loading on the thermal diffusivity of adhesive were investigated using Laserflash.

The purposes of this research were to 1) study attitude 2) study youngsters’ needs 3) study effects and problems and 4) study ways to prevent and solve youngsters’ online games and Internet addiction problems. The samples consisted 200 people. Tool were questionnaires and questionnaires for interviews. The statistics used in data analysis were percentage mean and standard deviation. The findings were as follows: 1.Most parents and guardians knew Online games and Internet but never used them. Most of them thought had negative effect learning and disadvantages. 2.Youths knew Online games and Internet since they were below 12 years old and they played them for 1 to 2 hours per day at internet shops. The Pb games was most played. Facebook was the website which youngsters most used. 3.Youths accepted that Online games and Internet caused expenditure of money being without friends irritability and lack of waiting behavior. They gave their opinions that youth age as well as Online games and Internet time should be limited. 4 the ways to prevent and solve problems wars as follows: Family must generate immunity for children by fostering them and providing them with quality time Teachers must support their students to do creative and enjoyable activities in various school clubs. Game Online owner must attend moral in order to have responsibility and moral consciousness of the society and Youths must have self-control and discipline must manage time limit.

This study was undertaken to determine effect of bio-extract fermented from pig placenta and effect of wood vinegar solutions on seed germination percentage and speed of germination of 2 rice cultivars Chai Nat 1 and Sang Yod Phattalung. The experiment was conducted in factorial in completely randomized design with 2 factors and 4 replications. The first factor was ratios of the solutions to water and the second was duration for seed incubation. The results demonstrated that wood vinegar showed more positive effect on rice seed germination performances than that of bio-extract. Speed of germination was affected by an inter-action between the dilutions of the solutions and the duration for seed incubation. In Chai nat 1 experiment the seed soaked in 20 times dilution of bio-extract and subsequently incubated for 24 hrs increased speed of germination of the seed. While soaking the seed in 400 times dilution of wood vinegar and incubated for 24 hrs could enhance both percentage and speed of the seed germination. In Sang Yod Phattalung experiment soaking the seed in 50 times dilution of bio-extract and subsequently incubated for 48 hrs or soaking the seed in 300 times dilution of wood vinegar and incubated for 48 hrs could enhance both percentage and speed of seed germination. According to the results we concluded that soaking rice seed in bio-extract of pig placenta fermentation or in wood vinegar solutions could enhance the seed quality.

This research aimed to investigate the students’ professional problems during their internship from the perception of workplace. The population was 66 informants who the sample was 43 selected by purposive quota sampling Research data were analyzed by descriptive statistics percentage mean and standard deviation and multiple regression analysis The research finding showed the findings showed that (1) the students’ fundamental proficiency problems in front office department were overall at the “Little Level”. A questionnaire 3 dimensions: the students’ fundamental proficiency core proficiency and additional proficiency problems. (2) The students’ fundamental proficiency problems in food and beverage department were overall at the “Little Level”. A questionnaire 3 dimensions: the students’ fundamental proficiency core proficiency and additional proficiency problems. (3) The students’ fundamental proficiency problems in housekeeping department were overall at the “Moderate Level”. A questionnaire 3 dimensions: the students’ fundamental proficiency core proficiency and additional proficiency problems.
