Bifurcation diagram is an important mathematical tool for the analysis of ferroresonance in the electrical power system. Bifurcation diagram can clearly present the behaviors of the nonlinear system. The general method for the generation of steady state bifurcation diagram is based on Ordinary Differential Equation (ODE) of the simplified single-phase circuit and the continuation technique. This paper proposes the application of PSCAD/EMTDC simulation program and the bruteforce technique to generate time response of the three-phase power system. A new device tool “Multiple Poincaré Map” is created and used with File Read and XY Plot to produce bifurcation di agrams with respect to changes of controlled parameters. Two examples related to ferroresonances in the distribution systems are presented. Bifurcation diagrams generated with the PSCAD/EMTDC and Multiple Poincaré Map confirm that the results from the simulation are in good agreement with the results from field tests.

The two purpose of this study were as 1.To study the students opinions of Rajamangala Institute of Technology Bangkok Commercial Campus to the learning process according to the Article 24 of the National Education Act B.E. 2542. 2.To compare the students opinions of Rajamangala Institute of Technology Bangkok Commercial Campus to the Article 24 of the National Education Act B.E. 2542 perception by sex and field of study. The 300 samples used in this study were the undergraduate students of Rajamangala Institute of Technology Bangkok Commercial Campus in 8 fields of study from the faculties of Business Administration Mass Communication and Arts. The findings found that most of the samples were in the medium level of opinions to the learning process. It was also found that the accounting field was in the highest level of opinions in the contents of learning given and the business english field was in the highest level of opinion in the activities of learning atmosphere environment of learning and materials of learning. It was found that sex was no statistical significance and field of study was statistical significance at .05

This research was aimed to study the qualification of Kluaynamthai Hospital’s Personnels in three aspects; nutrition knowledgeconsuming behaviorand nutritional status. The research was also to study the relationship of the three aspects. The Stratified Random Sample method was used. There were 236 samples. The tools used were questionnaires and the 2008 annual check up information of the sample group. The data were analyzed by using frequency percentile mean and standard deviation. The statistic used was Chi-square significant level at 0.01 – 0.05. The study revealed that 65.68 % of Kluaynamthai Hospital’s Personnels had very good nutrition knowledge and 26.69 % 6.78% 0.42% and 0.42% had nutrition knowledge at good moderate passing and not passing respectively. The average of 2.91 of the group had good consuming behavior and the frequency of good consuming behavior at 2.69. or 91.95 % of the group’s consuming behavior was less affected by mass media. 49.58% of the group had normal nutrition status while 35.59% and 14.58 % had over nutrition and below nutritional status respectively. The study of the relationship between the nutrition knowledge and the consuming behavior revealed that there was the significant relationship between the two variables at significant label of 0.05

The article is aimed to study of outcome on student loan and study motive background (gender provinces amount of siblings parent education parent career family Measurement and method are studied from documents and questionnaire. The result show that student loan administration fix toohigh families income of students. 2) lack of the ckecklists in allocation. 3) lack to the payment back to student loan. 4) lack of the follow-up and evaluation The satisfaction of higher education students on student loan according to gender provinces amount of siblings parent career family income is not significantly different except parent education is significantly different at 0.01.

As the Faculty of Architecture and Design Rajamangala University of Technology Phra Nakhon has a vision of a leader in the development of professional education on architecture and design for graduates who will meet international standards of scientific and technological competence it continually develops the quality of education and facilities to provide the educational management that meets students needs. This study aimed to state the problem and needs in educational management and focused on 300 of students of the Faculty of Architecture and Design in academic year 2009 consisting of 108 of the first year students 86 of the second year students 51 of the third year students and 55 of the fourth year students. The study methodology was done by 300 of questionnaires. Data were analyzed by the SPSS program for mean frequency and percentage. T-test was for standard deviation.
