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.

This research aims to develop the cement board from vesicular basalt fragment which reinforced with steel wire mesh. The ratio of Portland cement type1: fine sand: vesicular basalt fragment: sodium silicate: tap water was equal to 1: 2: 4: 0.03: 0.55 by weight. The 5 sizes of steel wire mesh (steel wire no.25) were installed including: 3/8” 1/2” 5/8” 3/4” and 1”. The cement boards were produced by compression machine. The property tests of cement-bonded fiberboard followed the TIS. 878-1994 standard (cement bonded particle board: high density). From the results the 3/4 of steel wire mesh size was the most suitable size for reinforcing the cement board from vesicular basalt fragment. This developed cement boards was the construction materials which had the high bending strength good thermal insulation and moisture protection properties.

The research aims to study and develop the Kaolinite mixed with cement powder for the mass wall. The Kaolinite development process to improve the characteristics. The Kaolinite mixed ratios are 10% 20% 30% and 40% and the result indicated that the experiment mortar-mix ratio at 0:8:2.75:0.2:0.05:0.04:0.5 of cement powder sand Kaolinite limestone superplasticised and clean water compared to No MK control sample covered ASTM standard in tensile strength more than 100 ksc compressive strength of MK20% with superplasticised at 434 ksc. The water absorption values under the standard passed
