- The objectives of this independent study were to study the knowledge and levels of understanding with regards to the safety of personal information in the Bangkok Metropolitan area, etc., and to provide the information gathered from the research to researchers for further studies. The example group in this study was population using computers in Bangkok of which the survey tool is 420 questionnaires. The statistics utilized in this study are percentage, arithmetic mean, standard deviation and statistic. Hypothesis testing of the differences between the populations mean of the two Independent Samples t-test and the hypothesis testing of the One-way ANOVA of more than 2 groups of population. If differences occur, tests will be processed by using the method of the Least Significant Difference (LSD). The study reveals that Grade A knowledge was only presented by 3.3% of the population and 31.4% belongs to Grade F level in safety of personal information. Therefore, it can be concluded that 68.6 % of population using computers in Bangkok have an average level of knowledge. Hypothesis testing reveals that different personal factors such as gender, age, educational level, occupation and work experience differentiate the knowledge and understanding regarding the safety of computerized personal information. The only exception is that the subjects’ level of income does not affect the knowledge and understanding of such matters. 1
- The objectives of this study were to 1) determine the efficiency of cartoon animation for English subject on tense for primary 5 students, 2) compare the achievement before and after learning, and 3) identify satisfaction of the students who learned from the cartoon animation for English subject on tense for primary 5 students. The samples used in the study were 30 primary 5 students at Chumchonlertphinitphittayakhom School under the Pathum Thani Primary Educational Service Area Office 2 in the 2nd semester of academic year 2017. The research instruments were the pretest and posttest, and the questionnaires on students’ satisfaction toward the cartoon animation for English subject on tense. The statistics used in the study were percentage, mean, standard deviation, and t-test for dependent samples. The findings revealed that the efficiency of cartoon animation for English subject on tense for primary 5 students had KW-CAI efficiency on benchmark of 80.80. The students’ learning achievement after using cartoon animation was higher with significant difference at a .05 statistical level. The average level of students’ satisfaction toward the cartoon animation for English subject on tense for primary 5 students was high. 1

- This independent study had the objectives to study general data of brand equity of Ford automobiles by utilizing questionnaires as the tools in data collection. The sample group was consumers using Ford, total 400 samples. Statistics used in data analysis were descriptive statistics, frequency, percentage, mean and standard deviation. The Independent Samples t-test was used to test the difference between two independent groups whereas One-way ANOVA (F-test) was used to determine whether there were any significant differences between the means of the three or more independent groups. Besides, Least Significant Difference (LSD) was also used to determine the minimum difference between any two means. From the study result, it found that most respondents were male, (60%), aged between 31-40 years (43%), had Bachelor’s Degree (67.5%), had occupation as private company employees (43%), had monthly income between 28,001-38,000 Baht (46.5%), were married for 53%, and type of automobile that they used was pickup truck. Moreover, from the testing results, it found that the different age, education level and income, had different recognition in brand equity at a significance level of 0.05. 1
- This thesis presents a construction of a three phase linear induction motor together with its drive control. The drive control of such motor is analyzed and then also built. The direct torque control in this thesis generate a voltage and reference frequency by using a motor torque and its magnetic flux error in order to control such linear motor. However the space vector modulation method are utilized in this work instead of using a stator flux and look-up table technique. A 1kW, 16 pole of three phase single-sided linear induction motor is constructed and built in this work. The motor drive is also built within a 10 kHz switching frequency. However the controller is composed of by using a TMS320F240 DSP board in order to generate a control signal for a inverter circuit, and using a DSPACE 1104 real time interfacing card in order to implement for a direct torque control method. Simulations results of the three phase linear induction motor was done by using MATLAB/SIMULINK and experimental results of such linear induction motor was also analyzed in this work. It shows that the proposed system provides a fast response of torque control comparing with a traditional V/F control. In practice, a transition time of motor torque is about 50 ms, while such controller of the linear induction motor has a command torque at 5 Nm. 1
