The purpose of this study was to compare undergraduate students reading writing performance and interest in learning English through reading instruction with and without computer in PowerPoint Program at Rajamangala University of Technology Phra Nakhon Bangkok Commercial Campus. The subjects for this study consisted of 80 undergraduate students in the first semester of the 2005 academic year of Rajamangala University of Technology Phra Nakhon Bangkok Commercial Campus. They were selected by using simple random sampling and divided into the experimental and control groups with 40 students in each. The randomized control group pretest -posttest design was used in the experiment. The experimental group was taught through the method in the reading instruction with computer in PowerPoint Program whereas the control group was taught through the method in the reading instruction without computer in PowerPoint Program. Each group was taught with lessons of the same content for sixteen 150 minute periods. The instruments used in the study were English reading writing performance tests and interest in learning English. The t-test for independent samples score was statistically used for data analysis. The results of the study indicated that: 1. The English reading performance between the experimental and control groups was significantly different at the .05 level. 2. The English writing performance between the experimental and control groups was not statistically significant. 3. The interest in learning English between the experimental and control groups was significantly different at the .05 level.

The purpose of this research were to develop the efficiency of Computer Assisted Instruction (CAI) in Bio – Organic chemistry and to compare the leaming achievement in Bio – Organic chemistry the sample consisted of 35 and 39 student in Department of Food and Nutrition Faculty of Home Economic Technology Ragamangala University of Technology Phra Nokhon 2008 academic year. Research instrument were the CAI and Achievement test in Bio – Organic Chemistry in Carbohydrate. The achievement test comprised 40 item. The data analyzed by statistical computer program. And used mean percentage and compare mean by t-test

The pupose of this study was to examine The Factors of the Students That Effect To Produce The Graduates of Rajamangala University of Technology Phra Nakhon. The focused on the level of The Factors from students effecting to produce the graduate of the University Tajamangala of Technology Phra Nakhon. The sample 350 students. Data was collected from a set of Questionnaire and analyzed with a statistical software program. The statistical method were percentahe average t-test One-way ANOVA. The level of statistical significance was set at 05 The result indicated that the level of the Factors from students effecting to produce the graduate of Rajamangala University of Technology Phra Nakhon was high. In hypothetical testing the students was influcnced by the following factors ; Age Faculty Leaming Grade of Education. Education before leaming Household Behavior of students Leaming situation and The satisfied of bachelor degree excepted sex and course of study.

According to my research that follow a purpose for educated variable of design and a mould building pattern. Bulging letters on a smooth sheet keyboard for produce a supply data device for comfortable to supply data by touching. Reduce use your eyes for looking on keyboard and help to relax your hands muscle from typing. From example in 50 people statistics that use analysis data the percentage the stan4ard deviate value t-test value. From research result design and a mould building pattern build from bulging letters on keyboard lumps from a copper mould building. This use metal that pass Electrical Discharge Machining Technology: EDM pump on Silicon and fume by heat for silicon freezing. Produce process consist of Lathe Milling Drilling Grinding Wire Cutting Machine Cutting Edge Grinding Wheel and Assembly and Fitting that use with NC and CNC (Numerical Control and Computerized Numerical Control) Software that use to control machine consist of CAD (Computer Aided Design) that use for writing and CAM (Computer Aided Manufacturing). the use of puffed up alphabet keyboard research because of knobs on the keyboard made of Silicone has soft and bend follow the characteristic of that alphabet. When you place fingers on the keyboard the movement of fingers tip from fondle the location of alphabets for check the difference between each alphabet. From the result people who are expert or have fast for touch screen typing test to find thee difference of seeing the keyboard before use of typing practice program use finger tip for fondle type of each alphabet. In case of people who cannot remember alphabet s keyboard they will adjust the movement of finger tip for realize and have accurate location of alphabet for correction of location of finger that place for reduce wrong typing and reduce seeing of keyboard accordingly to help to allow the comfortable from putting the data by touch screen system Keyword : keyboard ldata enter equipment I knob keyboard Isilicone I puffed up alphabet I block pattern! puffed up typing Itouch screen typing

Recently scientists have focused attention on soil as a major source and sink for atmospheric CO2. Three replications of two-depth soils from eleven different ecosystem types from Sakaerat Environmental Research Station (SERS) Sakaerat Silvicultural Research Station (SSRS) and Suranaree University of Technology (SUT) Nakhon Ratchasima were collected during the first week of March 2010. The soils were then incubated at 25°C for three days and measured their respiration rates. The highest soil respiration rate was found in sunflower with 0.823 μmol CO2 g-1 h-1 while the lowest was found in eucalyptus plantation in SUT with 0.005 μmol CO2 g-1 h-1. Additionally between two natural forests at SERS the respiration rate of dry evergreen forest was higher than in dry dipterocarp forest with the value of 0.037 and 0.016 μmol CO2 g-1 h-1 respectively. Whereas the soil respiration rate at SSRS forests was highest in the eucalyptus plantation (0.048 μmol CO2 g-1 h-1) and lowest in acacia plantation (0.027 μmol CO2 g-1 h-1). The overall respiration rate was higher for soils from 0-5 cm than 5-15 cm but not statistically significant difference. Soil water content and pH were positively significant related with soil respiration (p<0.01). Soil carbon however was also positively significant related with soil respiration but in lesser degree (p<0.05). Therefore soil water content and pH should be major driving forces for soil respiration.
