The purpose of this research was to design and develop an internet management system using radius protocol for a school. The system was developed by PHP language MySQL database and radius protocol. It allowed an administrator to grant users permission to access the internet manage their accounts check their status and record their usage history in files in addition to teachers being able to limit the use of the internet in their classrooms. The system evaluation process was divided into two parts. First the efficiency of the system was evaluated by the administrator and it was found that the system can work as required. Second the system performance was evaluated in terms of network security functional requirement and processing speed by the completion of a questionnaire by five experts. User-friendliness was evaluated by the completion of a questionnaire by 115 teachers and students. Results showed that the average efficiency was 4.22 with a standard deviation of 0.07. It can be concluded that the effectiveness of the developed system was at a high level and its application was beneficial for other organizations

This paper presents the method to reduced electromagnetic interference from electronic drive for LED lamp to achieve the TIS standard No.1955-2551. According to standard it must have been tested for magnetic field compatibility that are included Magnetic Field Emission: ME Conducted Emission: CE and Coupling Decoupling Network: CDN. The 3 LED lamp which defined as Type A B and C were tested. Each lamps has 16 watt electric power and was different electromagnetic interference of electronic drive. After that the reduce electromagnetic interference circuit has been designed for low frequency. This circuit test was based on Conducted Emission test only. The integrated design was preferable to reduces electromagnetic interference for LED lamp drive device type A to the TIS. standard No. 1955-2551. That design circuit was been trialled in LED lamp drive device type B and C in order monitor efficiency of reduce electromagnetic Interference. The results showed that design circuit can reduce electromagnetic interference from LED lamp drive device type A and B to the standard. For LED lamp drive device types C the design circuit can reduce electromagnetic interference but it still has not achieve the standard.

The research objective is to analyze usage and exposure of the social media network of Faculty of mass communication technology. A user need of the social networking censorship is based on a survey research. Samples used in the study - teachers alumni and students within the faculty total number is 306 people. Sampling was started in a fiscal year of 2014 with Stratified Random Sampling method. Statistics are used to analyze the data values in percentage average and standard deviation for One-way ANOVA and t-test (LSD). A result of this research shows that based on the findings issues can debate as follows: A usage of devices for surfing network of social media the most of smart phones account for the social media network at home of the time spent - common period turnarounds 20:01 to 00:00 hrs. A representation of a daily usage on network of social media is 4-6 hours/day. Equivalent today-per-week using of social media networks is active online every day. The smart phone is in use at all times. Meanwhile the popular social media network daily user accounts from experienced in the use of social media networks. Most of the more than four years representational use for news/information perception. The most common tool of online social media network is Facebook. Faculty’s people a use of social media networks Facebook applications take into account essentially. The exposure of the social media network can be specifically considered as: the streaming information perception of the faculty’s network of social media is moderate. Considering the news that graduation ceremony in 2013 social interaction with the media is moderate. It is considering whether to press “Like” button on Facebook user’s expression from media relating to the Faculty is the highest. The use of social media within the network is moderate.

This research has a purpose. To study the perception level of the Faculty of Business Administration personnel on Internet news dissemination. This may affect the offense under the Computer-Related Crime ACT B.E. 2550 (2007). This research is quantitative research with the questionnaire. (Questionnaire) The samples were staffs of the Faculty of Business Administration. Rajamangala University of Technology Phra Nakhon Bangkok. The researcher conducted several statistical analyzes including Frequency Percentage and Mean. The sample consisted of 60 people 22 men and 38 women 36.7% and 63.3% respectively. The age group was between 18-45 years. There were 30 and 25 respectively and there were 83 graduates in the masters degree 83.3 followed by doctoral degree and bachelors degree. Concluding that the 36-40 age group had the highest level of knowledge the average was 3.571429 followed by the 31-35 age group 41-45.46-50 51-55 respectively and the smallest group. In the age range of 21-25 the mean is 2.809524 and the level of separation is based on the degree. Masters degree has the highest cognitive level of 3.425714 followed by undergraduate level. And the lowest degree is the diploma level.

The objectives of this research were (1) to study media exposure behavior of technology technology learning behavior technology using behavior in daily life and self-development of elderlies in Bangkok (2) to compare between demography and self-development of elderlies in social network and (3) to study effects of factors to self-development in social network of the elderlies in Bangkok. The data were collected from 400 elders who were elderly 60 years and over residing in Bangkok Metropolitans. Data analysis employed frequency percentage arithmetic mean (X) standard deviation (S.D.). Statistics used for hypothesis testing included chi-square t-test One-way Analysis of Variance and multiple regressions. The results of study showed that:
