The objectives of this research are: 1.To study the relationship between the general subjects scores and the students educational achievement. 2.To study the relationship between the general subjects scores and the students work achievement. 3.To study the relationship between students general subjects scores and their ethnical behavior. 4.To study the relationship between students general subjects scores in Social Science and/or Humanities and the students work achievement. 5.To study the relationship between students general subjects scores in Social Science and/or Humanities and the students ethnical behavior. The research data were from four sets of questionnaire. The first set was given to all student samples who were going to graduate in the 2/2542 academic year within the Center of Rajamangala Institute of Technology. The samples were from the stratified random sampling. The first set of questionnaire 230 items was brought back 100% completely. The second set of questionnaire was Qiven to teachers or advisors of the samples above. The third set of questionnaire was given to samples employees. The fourth set of questionnaire was given to the employed samples. Percentage Mean Pearsons Product Correlation Co-efficient and Multiple Regression were used for data analysis by the SPSS/PC+ The research findings are as follow: 1.Students achievement showed positive relation at the middle level to their general subject scores. 2.Students achievement showed non-relation to their general subject scores. 3.Students ethnicai behavior showed the very low level relation to their general subject scores and these two variables showed the opposite relation. 4.Students work achievement showed non-relation to the general scores in Social Science and/or Humanities. 5.Students ethnical behavior showed positive correlation to their general subject scores in Social Science and/or Humanities Moreover it was found that the students general subject scores in Social Science and/or Humanities could predict their ethnical behavior. Other variables showed non-significant difference to the prediction-equation at the alpha level of 0.05. Researchers proposed that all vocational faculties within The Center of Rajamangala Institute of Technology who would like to implant or promote the students ethnical behavior should organize their curriculum based on Social Science and/or Humanities especially the SUbjects on social and human behavior development i.e. Life and Social Skills Human Relations. Researchers proposed that there should have ongoing research about variables components patterns teaching methods and activities for each subject concerned to see the outcome of students ethnical behavior development. Moreover the repeated research should be done to compare the Rajamangala Institute of Technology students work achievement with the students from the other universities and there should have the study of relationship between students vocational subjects and their work achievement so that the findings should have been considered for the curriculum adjustment.

The purposes of this research were 1) to study the participation of parents in educational management in children educational development centers Prapadang District Samutprakarn Province 2) to compare the parents’ participation level. 3) to study the problems and suggestions of parents. The data were collected from 335 parents. The instrument used to collect data was a questionnaire. Data were processed by percentage mean standard deviation t-test and one-way analysis of variance (ANOVA). The results of research were found that 1) participation of parents were at the least level. 2) to compare the parents’ participation it was found that gender was not different while the participation of parents with different vocation and education level found the difference 3) the problems were the parents had to work and were busy. The suggestions were PTA and should find finding volunteers for the centers.

The preparation of silver fiber with electrospinning process was a principle to impulse the iron within the polymer solution. The polymer solution jetted onto the ground collector in nonwoven form when the electric charge was higher than the polymer surface tension. This research had 3 key factors consideration that were electric power supply polymer concentration and length between needle tip and aluminum ground collector. The electric voltage was 6 9 12 15 and 18 kilovolt the ratio of Ag : polymer solution (%wt) was 1:10 1:20 and 1:30 and the length between needle tip and aluminum foil collector was 6 7 8 9 and 10 centimeter respectively. The fibers obtained were investigated and compared to the fiber morphology by Scanning Electron Microscope and the anti-bacteria test via AATCC test method 100-1999 (Quantitative) and 147-1998 (Quality). The optimal electrospinning condition was 18 kilovolt the ratio of Ag : PVA (%wt) was 1:20 at length 7 centimeter. The fibers were continuous average diameter as 183.3 nanometer and available to against bacteria.

The objectives of the study were to find the survival probabilities the hazard rates of dropping out of the technical diploma level students at Rajamangala University of Technology Phra Nakhon North Bangkok Campus and the factors influencing on the hazard rates of students dropout. The sample was the students enrolling in the university in 2005. The study found that for the first semester the survival probabilities of students in all divisions were high ranging from 0.9210 to 1.00. For the second semester the survival probabilities of students in all divisions ranged from 0.7820 to 0.8815 except Industrial Technology which had a maximum value of 0.9295 and Metal Technology which had a minimum value of 0.6271. For the third and the fourth semester there were 6 divisions which had survival probabilities ranging from 0.7142 to 0.7971. They were Tool and Die Making Computer Technology Electrical Technology Electronics Automatic Machine and Production design. There were 4 divisions which had survival probabilities ranging from 0.8275 to 0.8732. They were Mechanical Tool Technology Business Computer Mechanical Power and Industrial Technology. The division of Metal Technology had the minimum value of 0.5932. For the first semester the hazard rates of dropping of students in all divisions were low ranging from 0.00 to 0.0822. For the second semester the hazard rates of dropping of students in all divisions ranged from 0.1260 to 0.2458 except Industrial Technology which had a minimum value of 0.0730 and Metal Technology which had a maximum value of 0.5221. For the third and the fourth semester the hazard rates of dropping of students in all divisions ranged from 0.1355 to 0.2962 except Metal Technology which had the maximum value of 0.5932 and Tool and Die Making which had the value of 0.3364. The factors influencing on hazard rates of students dropout were place of previous school region of previous school and grade point average of previous school. The hazard rate of dropping of students graduating from schools in the central region (not including Bangkok Metropolitan Area) was 43.8% (0.562 times) less than the hazard rate of dropping of students graduating from schools in Bangkok Metropolitan Area. The hazard rate of dropping of students having grade point average of 3.10-3.50 and 3.51-4.00 from previous school was 43.1% (0.569 times) and 63.7% (0.377 times) less than the hazard rate of dropping of students having grade point average of 2.00-2.50 respectively.

The objectives of this research are to study the direction and goal of producing under Graduate students and to study the congruity between the planned strategy of the Rajamangala University of Technology Phra Nakhon and the national development plan and educational plan. Moreover to survey the managing problems at the present time the planned strategy of the Rajamangala University of Technology Phra Nakhon (2005-2010) were studied by the Content Analysis method and the Survey Research method and 400 University staff members questionnaires on administrative information were analyzed. The results of the research revealed as follows: the university focuced on producing more students the in science and technology students. The planned strategy of the University was congruent with the national development plan and educational plan. The administrative problems faced by the University included human resource management workforce deficiency lack of planning lack of qualified personnel working in certain positions poor welfare management and little incentive.
