The research on opinions and demands of viewers digital TV via applications has objectives as follows 1. to study the opinions and needs of users who view digital TV via application; 2. to study the opinions and needs of the management from agencies organizations public sector private sector state enterprises and scholars involving in television media industry; 3. to establish guidelines for developing appropriate program format for digital TV application. The researcher used mixed research methodologies by combining two methodologies qualitative research and quantitative together. Both methodologies were used in conducting this research simultaneously in a single period. Data of both methodologies was collected and analyzed separately whereas the results were combined and interpreted. Then the results were discussed by comparing the similarity and difference of both methodologies. The qualitative research methods consisted of document review observation and in-depth interview. The quantitative research methods consisted of questionnaire from sample groups and statistical analysis. Research results revealed that according to opinions and demands of viewers digital TV via applications (most people downloaded digital TV viewing application on Android platform) the most watched channel is channel 8; on average they watched digital TV 5 days per week with minimum 3 hours of viewing time; the types of program that people watch regularly were dramas which they can watch offline afterwards. Overall the users had positive attitude towards their experience in using digital TV application with average score totalling 3.96. The factor that received the highest score was the convenience of using digital TV application which received average scores totalling 3.96 (agree). The second highest score which totalled 3.85 (agree) was usefulness. Usage protocol received 3.79 scores (agree) and service received 3.56 scores (agree). The most important factor according to the sample groups when choosing digital TV application was quality. Features format and structure were then considered respectively. As for the opinions of the management from agencies organizations public sector private sector state enterprises and scholars involving in television media industry they wished to see constant development in digital TV programs that would keep up with the ever changing technology as well as marketing factors relating to advertising incomes and other incomes.

The purpose of this research was to 1) study the students leisure time. 2) study the learning patterns of the students of the Faculty of Industrial Education. And 3) find out the relationship between leisure time and learning styles of the students of the Faculty of Industrial Education Rajamangala University of Technology Phra Nakhon. The samples of this research were Faculty of Industrial Education 245 students Rajamangala University of Technology Phra Nakhon were sampled stratified by stratified random sampling. Tools used in this research were questionnaire about the leisure time habits and the learning patterns of the students. The results of the research were; firsty the study of students leisure time behavior. Rajamangala University of Technology Phra Nakhon showed that the leisure time of students The overall score was moderate.The students leisure time is the interaction activity followed by the leisure activity. Learning Activities and health activities. Secondly results of learning models showed that learning styles of students of Faculty of Industrial Education Rajamangala University of Technology Phra Nakhon At the mean level. it was found that there were 6 mean scores in the mean. The first was the collaborative learning model. Independent competitive and avoided. Finally Results of the relationship between leisure time and learning styles of students in Faculty of Industrial Education found that the behavior of leisure time in learning activities. Leisure activities There was a statistically significant positive correlation between the learning activities and the six learning styles at the .05 and .0.01 levels. There are positive relationships only with participatory learning models. At the .01 level of significance.

Nowadays a disc brake is one of important auto parts for motorbike cycle industry which effected directly to life safety. As the result this project aims to test the performance of the disc brake in order to study the physical disc brake that effects to braking distance and to be an alternative for testing the brake disc. Therefore the braking performance tester was designed and created in the single dynamometer which was not over 9.70•kgm2 as the moments of inertia of motorcycles. Regarding JASO T204:2001 this test was focused on the 3 different types of brake discs (i.e. normal type grooving type and perforated type). The tested temperature was at normal state of the brake disc temperature (60°C - 80 °C) and at high state (more than 100 °C). The braking force from 9.81N to 34.33N at master cylinder was tested. The result revealed that at normal temperature the braking performance of the three disc brakes (normal type grooving type and perforated type) was at 7.29 9.10 และ 9.50 m/sec2 per 1m2 of contact surface areas respectively. However the brake performance at high temperature was at 7.21 9.03 และ 9.46 m/sec2 per 1m2 of contact surface areas respectively. This result reveals that the most efficient disc brake at normal temperature was perforated type of disc brake which was 30.32% different from normal type of disc brake. Likewise; the perforated type of disc brake was the most performance disc brake at high temperature which was different from normal type of disc brake at 31.21%

The objective of this research was to determine and estimate the quality of ground water for producing village-tap water without pre-treatment in 3 districts Samchuk Nongyasai and Dermbangnangbuat districts Suphanburi province. Villagetap water was collected from 88 boreholes covered 17 sub-districts in June 2014 and January 2015 using standard method and then correctly preserved before analysis process. The result showed that pH conducted in filed using pH meter found in the range 7.0 to 9.2. Total hardness was found in the range of 110 to 590 mg/L as CaCO3. The concentration of Mn Fe Pb was found in the range of 0.08 - 0.88 mg/L nd - 1.88 mg/L and nd - 0.07 mg/L respectively. The concentration of Cd was to be non-detectable for all samples. The result found that total hardness was found higher value than standard quality water according to publish by Ministry of Natural Resources and Environment Thailand. The contamination of Mn and Fe in some samples was higher value than maximum allowable concentration. The problem of Fecontamination can extremely affect to physical properties of quality water. The production of household-water filtration in this work was modified from Bureau of Community Technology Department of Science Service Ministry of Science and Technology. The technology communication of the production household-water filtration was conducted by workshop procedure. The production household-water filtration was conducted step-by-step. All participants can produce the household-water filtration by themselves.

The research is study motives the affect participation in quality assurance personal of Faculty of Engineering Rajamangala University of Technology Phra Nakhon from example group of 182 people which classified by sex ages position educational degree field of work and working life. This research is used themethod is collecting data by question tool themethod is questionare tool fo collected data that could be two categorized include knowledge skills and attitudes. The questionnaire is five rating scales that analyze the result by frequency percent average the average of standard deviation and T-test independent by using one way ANOVA. The results were as follows : From one hundred percent of the personnel of Faculty of Engineering Rajamangala University of Technology Phra Nakhon whom 63.70 persent classified by the educational field and 36.30% support line are ready to enter into Asean community which could be seen average in whole picture. After considering in three aspects the result appeared that knowledge and skills of personnel are also average. However the attitude of personnel was considered in a high level. Hypothetic test result was found that there was no difference among the personnel with difference sex ages educational degree field of work and working life in their readiness in entering Asean Community. position
