The objectives of the study were to develop online article submission system of the Journal of Mass Communication Technology RMUTP and assess the appropriateness of then online article submission system of the Journal of Mass Communication Technology RMUTP. The program used to develop online article submission system using WordPress. The data was collected from a sample of 30 users who was evaluation the system. Data was analyzed by mean and standard deviation (S.D.). The results showed as follows: online article submission system of the Journal of Mass Communication Technology RMUTP was appropriate at a high level.

Deterioration of reinforced concrete deep beam structure caused by chloride is severe andtakes up wide area even though the structure is not exposed to sea water or brackish water. Even the structure which is far from sea water or brackish water is affected by this problem.When the reinforced concreate deep beam structure is affected by chloride steel reinforced inside the structure is corroded resulting in reducing the cross-sectional area of the reinforced steel affecting load capacity deflection and beam failure. If there is no repair or strengthening such capabilities are continuously reduced until it is no longer safe to use the beam. Therefore it is necessary to repair or strengthening the deteriorated structure to be safely used. This research investigated strengthening of deteriorated reinforced concrete deep beam caused by chloride with 4 formats of carbon Fiber sheets to seek guidelines for the most efficient strengthening. The resultshowed that the strengthening by the 4 format of carbon fiber sheet could increase ultimate loadcapability yet could not improve ductility of the deteriorated beam to become close to the beamthat is not deteriorated. The strengthening that could increase the maximum ultimate load capability was the table format strengthening. In addition the strengthening that the carbon fiber making 45 degrees with the length of the beam could best prevent diagonal cracks.

The objectives of the study were to produce 3D virtual reality media production for public relations of Rajamangla University of Technology Phra Nakhon and to study the satisfaction of the 3D virtual reality Media. This research was research and development. The data was collected from a sample of 400 samples. Data was analyzed by mean and standard deviation (S.D.). The results showed as follows: the sample group had the satisfaction to 3D Virtual Reality Media for Public Relations of Rajamangla University of Technology Phra Nakhon was at a high level.

The Objectives of the study were to study the tourists social media exposure and their knowledge and attitudes towards cultural tourism in Bangkok Metropolitan. This research was quantitative methodology. The sample consisted of 400 tourists in Bangkok Metropolitan and used non-probability sampling by accidental random sampling. Data were collected through a questionnaire as the research instrument. The results of this study showed as follows: In terms of basic information the sample mostly travels with a family. The source of information were relatives friends acquaintances who have traveled to that location. In terms of exposure to social network the sample mostly exposed to social media via Facebook short messages via twitter online video via YouTube photo sharing via Instagram website via Wikipedia and Webboard via Pantip. The sample exposed to social media average of 1 hour during 1.00-6.59 pm. on a smartphone. The majority of the sample used social media at home searching for cultural tourism information at a high level. The highest mean is finding transportation. The sample receives cultural tourism information at a high level. The highest mean is exposure to information about arts crafts sculpture traditions and festivals. The most trustworthy social media is Youtube. The social media influence had a high level because fulfilling objectives such as tourist attraction accommodations restaurants travel etc. In terms of knowledge the sample had a high level of knowledge of cultural tourism. The area with the highest level of knowledge was increasing the diversity of cultural tourism such as heritage tourism art tourism urban culture tourism rural culture tourism creative tourism and Thai local wisdom. In terms of attitudes overall the sample gave the highest priority is security.

This research has focused on the efficiency of using online media computer graphics based on concepts and theories of learning networks for students in computer science faculty of science and technology Rajamangala University of technology Phra nakhon because at present the network access can be accessed anytime the researcher has the idea to measure the effectiveness of learning in computer graphic courses. that students will have much interest 1) The population of this study consisted of 30 undergraduate students who attended the Computer Education and Training subject. The instruments utilized to design the lesson included. Tools used to develop lessons consist of a system LMS 2) The tools employed in evaluating quality of the online lesson consisted of the learning management plans a 20-item pre-and post-test an authentic assessment with rubric scores and a students’ satisfaction questionnaire. The results revealed that 1) The efficiency of the online lesson constructed was at 85/84 which was higher than the criterion set (80/80) 2) The students’ learning achievement was higher at .05 level of significance 3) The students’ satisfaction on the online lesson was at high level 4.31
