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.

The research paper is considered as quantitative work which has the following objectives: 1) to study Rajamangala University of Technology Phra Nakhon staffs A Study of behavioral factors associated with the use of online registration via the website.2) to study the relationship between their attitude and behavior towards using the registration system via the website. And 3) The compare problems in the system register online the website. Rajamangala University of Technology Phra Nakhon. The subjects of the study are 51 in-service teaching staff and 349 undergraduate students from 9 faculties. The instruments in this research consisted of questionnaire which the data were analyzed by using percentage mean standard deviation X2 t-test oneway analysis of variance and Scheffe’s method were utilized for data analysis. The results of the study revealed that: 1. The behavioral factors associated were age status and experience of used internet that related with behavior towards using the registration system via the website. In the objective of using the registration system via the website the time and location was statistically significant at 0.05 levels. 2. A good attitude in using the registration system via the online website had related with behavior of using the registration system via the website. The objective and the time of using the registration system via the website were different. 3. The behavioral factors associated were gender status and learning center which had related with different problem in using the registration system via the website.

The objectives of this research were to develop the online leave system for human resource management organization and to study the satisfaction of users toward the system. The system could support human resource department to manage employee information position department type of leaves right and calendar activity. The employee could take a leave and check status and history of absence. The employers could approve and check history of absence and also see calendar activity and absence report of employees. The system facilitated human resource department employers and employees including paper saving. Online leave system was developed with PHP used MySQL as the database management system and designed by Adobe Dreamweaver and Adobe Photoshop. The sampling group selected by purposive sampling was 30 users. The result of this research showed that the satisfaction of users was at good level.

The three types of Hamiltonian describing photon-photon and photon-phonon interactions within an optical ring resonator in which quantum noise in fiber optics is generated are given. The Markov-Born approximation and +P representation of photon states in phase space are used in order to eliminate the reservoir state variables by substituting all into the master equation to get the coresponding Fokker-Planck equation. The corresponding Langevin equation describing evolution of quantum states of an entangled photon is analyzed. The optimum results show that the occuring quantum noise can be reduced from the three main parameters where the surviving polarized entangled photon can propagate in the fiber optic system for a long time until photon processings are attained.

The objectives of this research were (1) to compare the educational results of online learning module which the results were separated by sample groups and educational objectives leveland (2) to evaluate the satisfaction for the use of online learning module of sample groups. The research hypothesis were (1) the proportion of sample who were good or better level of educational objective writing were equal or more than 0.5 and (2) mean of satisfaction for online learning moduleof educational objectives were equal or more than 3.5. The online learning module was developed with compute software and divides the study methods into 3 categories. Firstthe internet systemsecondthe asobe acrobat file (PDF) and third the help file of Microsoft.The content of each category was same and their constructional qualities were checked by specialist of educational measurement and computer.This module was applied to pilot project with 15 sample sizes and all samples of the study were 166 persons.All of them were volunteers. Results of the research were : After studying almost sample got the good level of education behavioral objective writing. The amount of objective writing for good level is mare than the amount of objective writing for medium level and the amount of objective writing for medium level is more than the amount of objective writing for poor level. The hypothesis testing was shown that : the proportion of samples who were good or btter level of educational objective writing were equal or more than 0.5 and mean of satisfaction for onlie leaming module of educational objectives were equla or more tgab 3.5 Result of research found that teachers students and other on educational area can use this online learning module for more developing educational materials.
