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:

This thesis presents the Power Quality (PQ) analysis of solar power plant 1MW and economic impacts in the distribution power networks. The case study focuses on the penalty fee (fine) from consume the reactive power less than the limit of the Provincial Electricity Authority (PEA) of Thailand. The fine have been charged up to 900000 baht per year. Therefore the thesis studies and purposes the possible solution by analysing the operating function of the inverter (supports reactive mode) installing the adjustable capacitor bank 1500kVar in the Medium Voltage (MV) level and lastly installing the adjustable capacitor bank 1500kVar in the Low Voltage (LV) level. The results shown that the possible solution that reduces the fine is installed the adjustable capacitor bank 1500kVar in the MV. The investment of this installation is cost 1800000 baht with the nominal operation over 10 years. The analysis of financial investment which bases on the Net Present Value (NPV) the Benefit-Cost ratio (B/C) the Pay Back period (PB) is presented the NPV at 4902971 baht B/C 3.72 and PB 2 year (with the Internal Rate of Return; IRR 49.7 percent).

This study the purpose of this research is to study a network of tourism of the central provinces in Thailand by topological analysis. Using the Gephi program to find that the trip by car or tour bus connects each province in the central region. Either 22 provinces. When analyzed with Gephi there are Nodes: 22 Edges: 43 and Undirected Graph. The results of the analysis concluded that Phranakhon Si Ayutthaya and Nakhon Sawan provinces are the provinces with the most significant relationships with the provinces. There are many routes connecting to various tourist attractions. It can travel to many provinces. And to study was conducted to analyze the tourist information of each province in the central region. Either 22 provinces. When analyzed with Gephi there are Nodes: 122 Edges: 145 and Undirected Graph. The overall conclusion was that Bangkok is the province with the most influential relationships with the nearest tourist attractions. The province is a popular tourist destination of the tour. There are tourist attractions that are of interest. It is a center that can travel to many provinces.

This research focuses on development of Multimedia and Interactive System through Network for Learning of Opportunities School. This system used as a channel for students to learn outside the classroom and used as a teaching management tool for teacher. Tools for system development were program Microsoft Visual Studio. Database management system with MySQL. Write commands to work with PHP and Java scripts. For evaluating efficiency of the developed system this research used Sample group to answer questionnaires. The population of research is teachers and students of the Bankamwa school (Weboonratsamakee) in totals 97 people. The result of experiment shows that group is recognized the performance of system in the higher level and the system has efficiency of working.

The climate change is a natural phenomenon and effect on atmospheric which is the media of wireless communication. For the high performance in the telecommunication system this study therefore aimed to study the variables affecting to signal strength of wireless networks. The values of temperature humidity pressure and the signal strength of wireless networks 5 GHz were measured. The sample of this study was 148 access-points of TOT in Yasothon Province. For statistical analyses Pearsons correlation and regression were employed. The findings revealed that: 1) the average level of signal strength was 69.44 –dBm. The average levels of temperature humidity and pressure were 28.085 ?C 73.145% and 1004.246 hPa respectively 2) variables that had great influences on signal strength of wireless networks consisted of temperature humidity and pressure and 3) ambient variables of temperature humidity and pressure could predict the level of signal strength at 76.8%
