This project deals with the application of microcontroller used for measuring the Q-factor of band pass filter. The procedure starts from the design creation and improvement of Q-factor and bandwidth of the filter. Solving the circuit filter frequency requirement the band must pass the filter. An instrument is necessary in the design of filtered frequency that shows the cut off at the rise edge and down edge searching the bandwidth and Q-factor of the filter. Finally the monitor will show all the values of every detail.

The objectives of this research were to 1) study perceived problems of students for educational management of Business Administration Faculty Rajamangala University of Technology Phranakhon 2) compare perceived problems of students for educational management classified by gender students year and field of study and 3) study needs of students for educational management of Business Administration Faculty. The sample studied were 341 undergraduate students selected by proportional stratified random sampling categorized by students year of study and simple random sampling was also used. The data was collected through questionnaires constructed by researcher. The statistics used for data analysis were mean standard deviation one way analysis of variance and Scheffes multiple comparison method. The results were as follows: 1.Problems concerning instructors content of study and method of teaching were less perceived by students. Evaluation and measurement teaching and learning management infrastructure concerns and instructional media and instruments were perceived as problems at intermediate level. 2.Students from different year and field of study and from different gender had statistically difference of perceived problems for educational management. 3.The highest needs for educational management concerning instructor aspect was love and understanding from teachers. Regarding the aspects of study contents method of teaching evaluation and measurement and teaching -learning management the highest needs were applying knowledge using an interesting instructional media evaluating according to contents organizing suitable study schedule of each term respectively. Enough and clean toilets as well as enough educational equipments were the highest needs for the aspects of infrastructure and educational media and instrument respectively.

The Purpose of this research is to study the Usage and Satisfaction towards Internet of Students at Rajamangala University of Technology Pra Nakorn. This study is a survey research. The instruments used in this research are questionnaire. The sample groups in this research were Rajamangala University of Technology Phra Nakhon 400 persons. The statistics by means of Arithmetic means percentage value t-test and Oneway ANOVA Analysis. The results of the study are as follow: 1.The students with different sex have no significant. 2.The students with different ages have no significant. 3.The students with different academic levels have no significant. 4.The students with different s~mesters have no significant. 5.The students with different faculty have no significant. 6.The students with different type of accommodation have no significant. 7.The students with different type of income have no significant. 8.The students with different expense have no significant.

The aims of this study were: (1) to develop an business news reading activity model using the reflective approach and group investigation and (2) to investigate the results by using the English business news reading activity model in business news reading achievement self-reflection of knowledge attitude and performance of learners and learners’ attitude towards the business news reading activity. The research procedure was comprised of 3 phases. In Phase 1 there was a creation and development of a new activity model which was verified by 3 experts. In Phase 2 the effectiveness of this activity model was developed by conducting the two-action researches. Moreover in the final phase this activity model was implemented with 36 staff members from private and public sectors that enrolled in this action seminar and the model effectiveness was evaluated against t-test. Different sample groups were utilized in each phase of this research : in Phase 2 the first action research was utilized by a sample group comprised of 40 second-year financial accounting undergraduates in the 1st Semester of Academic Year 2009 and the second action research was utilized by the sample group comprised of 36 first-year to third-year mixed-program undergraduates in the 2nd Semester of Academic Year 2009 ; and in the final phase the implementation and assessment of this activity model’s effectiveness was applied in which the sample group consisted of 36 staff members coming from the private and public sectors in Bangkok who enrolled in the English business news activity seminar. The research instruments were as follows : (1) the instruments for the study the creativity activity model were an activity-model’s quality evaluation and a Daily Business Vocabulary’s quality evaluation forms; (2) the instruments for the action researches were the learning achievement tests of the English business news reading the self-reflective learning checklist the learner’s behavior observation form and the attitude questionnaire; (3) the instruments for the activity model implementation and effectiveness assessment were the activity model the learning achievement tests of the English business news reading and the self-reflective learning checklist. The data were analyzed by means of percentage mean standard deviation and the t-test. The effectiveness of the activity model was assessed in terms of comparing the improvements of the mean scores of the students’ achievement in English business news reading comprehension. The findings of the study revealed that : (1) The English reading activity model using the reflective approach and group investigation developed by the researcher comprised 5 components which were as follows: Principles Objectives Content Learning-Teaching Procedures and Evaluation. The learning-teaching procedure synthesized from the study and used to teach reading in the English business news reading comprehension activity model using reflective approach and group investigation called (P) SPC2PAS model comprised 2 main stages and 7 sub-stages. Planning and SPC2PAS Model are as follows : S-Selecting the article/topic P-Planning and dividing labor C-Carrying out the study P-Preparing the public report P-Presenting the public report A-Authentic developmental evaluation and S-Self-reflection; (2) the development and assessment of the English business news reading comprehension activity model using reflective approach and group investigation revealed that: (2.1) The learners’ achievement of the first second and third action researches in the English reading comprehension was significantly increased at the statistical level of 0.05 which were the mean scores in the English reading comprehension of the mid-tests and post-tests which were significantly higher than those of the pre-tests at the statistical level of 0.05; (2.2) The learners’ spiral-learning development of the first second and third action researches using the activity model on self-reflection of knowledge attitude and practice reflected in the distribution of scores by percentage were in a range of good to very good level. In addition (2.3) three-group samples of all phases had a high to highest level-positive attitude towards the activity model using Reflective Approach and Group Investigation.
