The purpose of this research is to improve the physical and mechanicalqualities of natural rubber latex tiles. Water: surfactant: surfactant: 1: 2.75: 0.03: 0.30:0.03: 0.04 by weight and added with natural latex. In the ratio of Portland Cement Type 1: Natural Latex is 1: 0 1: 0.025 1: 0.05 1: 0.075 and 1: 0.10. Formed with compression presses at normal temperatures it was found that the optimum amount of natural latex For concrete reinforced concrete tiles the ratio is 1: 0.025. The tests in accordance with Thai Industrial Standard TIS 535-2556 are tested in 4 aspects. Dimensional stress test Water absorption test And waterproofness testing The value has passed the benchmark. And low thermal conductivity. Increasing the insulation of the roof as well. Can be used as a prototype product tile concrete roof natural latex. To produce commercially And there can be many local latex or rubber latex. To be more useful and valuable.

This research was aimed at analyzing the content and method of communication the embedded in ecotourism promoting media produced by the concerned agencies in Suphanburi province utilizing semiotics and concepts concerning tourism along with the indepth analysis on the phenomena in the areas under study as the research framework. The researchers focused on analyzing the meaning of signs apparent in the 5 types of media chosen as the study objects.

The main objective of the study was to understand image perception of the sample groups of 840 people towards Rajamangala University of Technology Phra Nakhon. The sample groups included the general public and high school students. The method for collecting data was the questionnaire survey. Rajamangala University of Technology Phra Nakhon is known among student and general public. Students knew it as a university while the general public knew it as a vocational college. Thirdly the outstanding perception of the institution among the students was in good academic level (mean=3.60). The highest perception score was about the schooling system (mean=3.60). The general public perceives more in details about its admission system (mean=3.52) and had good perception towards the institution’s good image (mean=3.52). Furthermore online media played a significant role in transferring information and creating the image of the institution among the sample group (mean =3.52 from student and 3.35 from general people). Fifth result gender did not play a significant role in perceiving the image of the institution. The last result was that gender played a statistically significant mark by .01 in media exposure among general public. In conclusion there is no distinctive difference between students and general public in having image perception towards Rajamangala University of Technology Phra Nakhon. However there is a statistical significance of .01 in exposure to online media both out of home media and personal media.
