In order to study the suitable condition for separation process the concentration of sodium hydroxide ranging from 0 -20 grams per liter and boiling time 15 30 45 60 75 90 105 and 120 minutes were performed. Web formation process was performed by wet laid method and polyvinyl alcohol was selected as binder in web bonding process. in order to study the suitable amount of binder in bonding process concentration of polyvinyl alcohol ranging from 1 2 4 6 8 and 10 % w/v coated on web surface and cured at 120 degree Celsius. Bursting strength as well as physical properties evaluation of non-woven fabrics was performed. For antimicrobial finishing process was performed by spray method and pad method. The finishing result was evaluated by MTCC test method 147-1998 (Qualitative) and 100 -1999 (Quantitative) The result was found that appropriate condition for fiber separation was recommended as follows: the amount of sodium hydroxide of 10 grams per liter and boiling time 60 minutes. The suitable amount of polyvinyl alcohol for web bonding process was 2 % w/v. Bursting strength of non-woven fabric was 53 kN/m 3 and padding method was a suitable method for antimicrobial finishing (antimicrobial area 0.3 millimeters )

The Research of this paper to propose the usage of Albizia lebbeck (L.) Benth. and Samanea saman Merill are fast-growing commonly found in Thailand. However these species of wood could not be utilized as structural components either economically or safely due to the lack of recommended values for their engineering properties. Therefore the objective of this research was to study their physical and mechanical properties based on statistical data obtained from 11 series of tests in accordance with ASTM 0-143. 0-198 and 0-1037. The number of samples for each test was large enough to ensure 99% interval of confidence. Then goodness-of-fit tests were performed for each set of data to achieve at least 95% level of confidence. Buildings analyzed included residences offices and schools. The buildings were limited to two-storeyed buildings with f1oor-to-f1oor height of 3.00 meters. Given to joists and beams were simply supported. Values of structural reliability were obtained by using accurate methods. Results from testing showed that engineering properties of both species of wood could be represented well by normal distribution. Reliability analyses and designs of wood sections for joists. beams and columns showed that designs of Joists and beams wWe controlled by deflection; whereas those of columns were controlled by buckling. Based on these reasons the governing basic variable for designs of wood sections was the modulus of elasticity (E). If the accepted value of failure probability (P) for serviceability limit states was set to be 10-4. the corresponding upper limit coefficient of variation (COV) of E would be 0.269. Similarty if the accepted value of P for Ultimate limit states was set to be 10~. the corresponding upper limit COY of E would be 0.210. Since COY of E for both species of wood were lower than limit COY mentioned above. they could be used safely as structural components. Proposed design procedures were similar to Working Stress Methods. The only difference from E.I.T. standard was live load. Instead of nominal live loads for residence. office and school as stated In the Municipal law. mean Ifve loads based on data gathered in Thailand were recommended. Wood sections obtalnec from numerical procedures proposed were as large as those obtained from WCCAL Software. Furthennore recommended wood sections and factor of safety (FS) were summarized in appendices. It was also interesting to note that the value of E for compression and tension parallel to grain of both species of wood could be used to predict the corresponding value of E for bending.

The sampled population of this process transferring the knowledge and skills of making extirpative orchids from mulberry -pulp paper includes the housewives of Department of Veterinary and the third agricultural division Department of Veterinary Thai Army and the interested people at Amphoe Mae Rim in Changwat Chaing Mai (88 adult persons sampling by completely random sampling method). Research instruments are the training course the questionnaire for evaluating the training course and the training procedures. Descriptive analyses (percentage and mean) are conducted to this work.The results of this work show that all of trainees are women (100%) age between 40 49 years (31.82%) and most of trainees were housewives (73.87%). Evaluation of the training course and methodology finds that objectives structures contents and activities of this course are more suitable level. The opinions about materials and documents using for this course and the training room are more and the most suitable level. The training procedures are the most suitable level. The assessment of expert (preparing to lecture the knowledge about contents of the course the skillful making of products. and ability to transfer the knowledge to answer the questions and to give advice) are the most suitable level. The comment from trainees is they continuously want to train courses that could actually bring back the knowledge and skills to do the occupation.

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.
