The objective of this research project is to develop an effectively applicable prevention of heat for concrete masonry unit wall. By using kaolin mixture coir rice straw and husk as a major ingredient in concrete to replacing usual stone dust the hollow non-load-bearing concrete masonry units obtained had the size of 70 X 190 X 390 mm. The test results showed that the reliably ideal ratio of these mixture materials had to be from the combination of kaolin coir rice straw and husk by replacing them at 5%: 5%: 15% and 50/0. The block obtained also had other certain qualifications such as Weight at 6.08 kg. water absorption at 7.96% and compressive strength at 65.4 ksc. Moreover these combined materials harbored heat capacity less than the standard concrete masonry units with the weight not more than 29%.

The purpose of this research was to study factors affecting the motivations and study the relationship between private intrinsic motivations and extrinsic motivations for teacher occupation under the economic crisis condition. The subjects in this research were 374 graduates of the Faculty of Education from Rajabhat University and Rajamangala University of Technology in the Central Region.

There was non significant relationships between age grade point average parentail income parentail expenditure mothers education parentail occupation and motivations for teacher occupation under the economic crisis condition at the 0.05 level.

We present the comparison of CDMA MAC protocol with and without beat noise by using 2-D optical CDMA MAC protocol over WDM networks. We use the asymmetric primehop sequence code. Moreover we analyse the effect of the number of available wavelengths in tenns ofaverage number of attempted to transmissions per time slot (offered load) and beat noise is considered. The presented numerical results based on the throughput and delay time versus the offered load. We divide into two parts. The first one we consider the effect of the number of available wavelengths. Another is the effect of with and without beat noise in the 2-D OCDMA over WDM systems.

Studies on Thai Language Teachers’roles towards the Conservation and Promotion of the Thai Culture in the Rajamangala Institute of Technology Central Campuses The purposes of this research were : 1) To study the general environment and roles of Thai language teachers towards conservation and promotion of Thai culture among the students and the community 2) To compare the roles of Thai language teachers being classified by their teaching experiences and education levels towards the conservation and promotion of Thai culture. 3) To study Thai teachers’ problems and obstacles in carrying out the said task. Samples of the research were 160 Thai language teachers. The instruments of the research were questionnaires. The data analysis was done on SPSS program. The result of the research showed that : 1) Most Thai language teachers had not been trained in the conservation and promotion of Thai culture. 2) There was no signifecant difference at level of 0.5 between the roles of the two groups of Thai language teachers in the conservation and promotion of Thai culture. 3) The Thai language teachers’ problems and obstacles in carrying out the conservation and promotion were lack of opportunities to acquire trainings or to participate in seminars on Thai culture lack of budgets document texts and audiovisual aids on Thai culture.

The research is development of web for promoting reading habit of Thai Youth: case study northeast region. The research objectives were to surway reading habit of Thai Youth. to create and development a web to promote reading habit of Thai Youth to try out and find learning achievement of the web to promote reading habit of Thai Youth as well as to compare behavior of Thai Youth using the web to promote reading habit of Thai Youth before and after using the web to promote reading habit the researcher had the sampling group from 3 following provinces : Nongkai Udomtanee and Khon Kaen. The statistics used consisted to percentage. mean standard deviation one way analysis of variance and t-test value. The reseach results showed that the quality of the web to promote reading habit of Thai Youth was 95.71/97.00 was more standard 80/80 and Thai Youth were after learning results more before use web to promote reading habit difference at 0.05 were to following hypothesis. Admintrators teachers and Thai Youth went for use all time. Because create Thai Youth that the quality and effective have learning achievement of the web to promote reading habit of Thai Youth create knowledge more intelligently. Such the government administrator teachers and librarian teacher to help promote reading habit of Thai Youth for transfer reading culture of Thai Youth all time. Because reading is wisdom to following achievement use development human and country no after others country in world.
