Degumming process is a fundamental process for silk yam and silk fabric finishing. The main objective is scouring the substrate such as silk gum (sericin) wax and fatty acid from silk fiber. The principle of degumming process is destroying the peptide linkage of amino acid in sericin structure into a small molecule which is soluble in water. The hydrolysis reaction performed by acid alkaline enzyme surfactant as soap and high pressure steam process. The conventional methods favor degumming with soap and sodium carbonate. This process has a problem on the surface area of silk. Proteolytic enzymes can answer this problem but it seldom use because of a specific condition and high cost. For this reason the insteading of papain enzyme from dry latex of Carica payapa Linn. was decided to use for silk degumming at any condition study. This research was concerned with the silk degumming using papain enzyme form dry latex of Carica payapa Linn. The degumming process was performed at the temperature vary from 55 -85 degree Celsius time fromlO to 40 minutes and the amount of dry latex ranging from 0 to 4% owf in order to study the suitable condition for degumming and surface morphology. The efficiency of degumming process was evaluated by determination of tensile strength and stainiqgJest with dire~~ dyes (C.1. Direct Red 80~StaIDing result.will be opposed to degumming efficiency. The result was revealed; the appropriate conditions for silk degumming with dry Carica payapa Linn. s latex were recommended as follows : the amount of dry latex solution of 4 % owf at 75 degree Celsius for 30 minutes. The degummed fibers leaves lustrous soft and surface smooth. This condition does not have effect to tensile strength and fiber surface.

The purposes of this research were to study and compare the satisfaction at rajamangala versity of technology Phra Nakhon Classifled by sex age education level type of personnel and experiences. The research samples were 1172 personnel from Rajimangala University of Technology Phra Nakhon. data was complied through the use of a questionnair with a statistical reliability of 0.9741 questionnaires retumed. There were 565 complete questionnares used in the data analsis process. the statistics used in the data analysis were percentage mean standard deviation t-test and f-test The results of the study found that personnel were with their role and position within the internation Afdairs Division at a mendium level (X=3.13 S.D. = 0.72) and documented the personality of offcers at high level (X= 3.62 S.D. =0.67) The results of the hypothesis testing yieded the following infomation : 1) A personnels sex did not have a signifcant statistical impact on the study with the only exception being the role and position (regitering a statistical difference of 0.05). 2) A personnels age did not have a singnificant statistical impact on the study. 3) A personnels educstion level did not have a sihnificationt statistical impact on the study whith the only exception being the role and position (registering a ststistical difference of 0.05). 4) A types of personnel did not have a siatical impact on the study. when fonusing on persons role and position there was a significant statical difference of 0.05.

Undergraduate educational management of Rajamangala University of Technology Phra Nakhon has mission point to science and technology vocational based on quality professional workers. Applied technologies on the engineering works have continuous and high progress. The researchers want to emphasis with human development for stepping up to professional works in The life long studying on working period of faculty of industry textile and fashion design Rajamangala University of Technology Phra Nakhorl. The research objectives are as follows: 1.To know they want to add more performance or to change from nature of the undergraduate field to others 2.To make the teaching discipllries for gain their standard lffiowledge higher 3.To study the life long studying on working period offacuity students and alumni. Domain of research and the participant groups 1.students who studying at Rajamangala University of Technology Phra Nakhon 2.Alumni want to change their graduated field to others or gain their performance. The research results found that the platforms are according to require on the life long studying in faculty of industry textile and fashion design have to stress on teaching for gain their performance with technology involvements such as production process coloring process textile printing graphic design and computer cutting forms according to short period not more than 6 months for studying. The discussions from participants point to continue to study for gain their performance first because economics rapidly changing and several firms want the best persons. They have a lot of best knowledge worker and high performance to work with them. The participants require 1-6 months for studying because the competitive workers in the specific working markets.

The purposes of this research were to : 1) compare creative writing achievement of students learning Thai Folk song and learning Thai Moders song as Aids ; 2) study the creative writing progress of the students in both groups by comparing between pretest scores and posttest scores ; find creative writing means scores and standanrd deviation of two student groups and find the percentages of the affective means scores and psychomotor means scores of the both groups. Samples were 62 students at the first level of Bachelor Degree from two classrooms : 31 students of each at Rajamangala University of Technology during 2008 academic year. The basis on Using Thai Language One mean scores of two student groups were not significantly different at th .05 level. The students were equally divided into two experimental groups. The first group learned Thai Folk song as aids while the second group learned Thai Modern song as aids. The research tools consisted of creative writing pretests and posttests instruments for development creative writing and creative writing lesson plans. The procedures were as following. Firstly the creative writing achievement tests were administered to both groups of students as pretests. Secondly sixteen creative writing lesson plans learning Thai Folk song as aids were given to the first experimental group while another sixteen creative writing lesson plans learning Thai Modern song as aids were given to the second experimental group. Finally the creative writing achievement tests which were similar to the pretests were administered to both groups as posttests. The results were as following. I) The creative writing achievement ofstudents learning Thai Folk song and leaming Thai Modem SOlg as aids was not significantly different at the .05 level. 2) The mean scores of two student groups between pretests and posttests were significantly different at the .05 level. The posttest mean scores of both groups were higher than the pretest mean scores. 3) The averages of mean scores and standard deviations of students learning Thai Folk song as aids were 15.31 and 2.80 and another experimental group learning Thai Modem song as aids were 15.63 and 3.18 4) The percentages of the affective mean scores and psychomotor mean scores of students learning Thai Folk song as aids were 87.64 and 87.22 and another group learning Thai Modem song were 87.18 and 86.01 respectively.
