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 aim of this research was to determine the effects of gender faculty and academic performance on the prevention of students to use to communicate on the Internet. Four hundred and thirty-three (male=225 and female=208) undergraduate students from 3 faculties including faculty of business administration and liberal arts science and agricultural technology and engineering in Rajamangala University of Technology Lanna Nan were used to fill in survey questionnaire. The results found that the gender had effected on the prevention oneself in the communication on the Internet. The male could prevent oneself more than female. In addition the student from engineering and science and agricultural technology could prevention oneself in the communication on the Internet more than faculty of business administration and liberal arts. However the academic performance had not affect on prevent oneself in the communication on the Internet. This study concluded that the prevention oneself in the communication on the Internet is affected by the gender and faculty but not the academic performance.

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%

The purposes of this research were to 1) study attitude 2) study youngsters’ needs 3) study effects and problems and 4) study ways to prevent and solve youngsters’ online games and Internet addiction problems. The samples consisted 200 people. Tool were questionnaires and questionnaires for interviews. The statistics used in data analysis were percentage mean and standard deviation. The findings were as follows: 1.Most parents and guardians knew Online games and Internet but never used them. Most of them thought had negative effect learning and disadvantages. 2.Youths knew Online games and Internet since they were below 12 years old and they played them for 1 to 2 hours per day at internet shops. The Pb games was most played. Facebook was the website which youngsters most used. 3.Youths accepted that Online games and Internet caused expenditure of money being without friends irritability and lack of waiting behavior. They gave their opinions that youth age as well as Online games and Internet time should be limited. 4 the ways to prevent and solve problems wars as follows: Family must generate immunity for children by fostering them and providing them with quality time Teachers must support their students to do creative and enjoyable activities in various school clubs. Game Online owner must attend moral in order to have responsibility and moral consciousness of the society and Youths must have self-control and discipline must manage time limit.

This study evaluated the genetic diversity of two natural populations of Neolissochilus stracheyi in Nan River watershed Amphoe Bokluea (BK) and Amphoe Mae Jarim (MJ). We analyzed microsatellite markers originally developed for Tor tambroides (Nguten et al. 2009). Three out of five microsatellite loci analyzed were polymorphic . Genetic variation within BK and MJ populations were not different. The number of allele per locus and allelic richness averaged over three loci was 2.33 and 2.67 for BK and MJ respectively. Observed heterozygosity value was 0.50 and 0.56 and the average expected heterozygosity was 0.41 and 0.53 for BK and MJ respectively. In addition the two populations were genetically distinct (P<0.05) and geographic isolation of two locations may explain this genetic pattern.
