The purpose of this study was to study and compare good citizenship characteristics of undergraduate of Rajamangala University of Technology Phra Nakhon in 4 aspects: ethics social economy and politics. The undergraduates were classified by gender academic years faculties and achievement. The samples in this research were 389 undergraduates. The study participates selected by stratified random sampling and simple random sampling. The 60 item questionnaires of rating scales was used as the research instrument. Percentage mean standard deviation t - test for independent sample F – test and Scheffe’s test analysis were statistical method to analyze data. The results were as follows: 1. Good citizenship characteristics of undergraduates all aspects were in relatively high levels that ethics was the highest politics was in the lowest rank. 2. There was significant difference for good citizenship characteristics of undergraduates at the 0.05 level among undergraduates in different gender different academic years different faculties and different achievement.

The purposes of this research are to examine the students’ Awareness and Behavior on Mobile Phone Hazardous Waste Management (ABMPWM) comparative studies of dependent variables among the levels of independent variables and their Corresponding correlation’s between their exposure to information and ABMPWM and to yield the appropriate means for managing mobile phone waste. The survey research using self-administered questionnaires was conducted on 450 random samples from 264027 students with study standing at junior and senior high school in Bangkok. The analytical statistical methods used were percentage mode mean S.D.(Standard Deviation) T-Test F-Test One-way ANOVA Analysis Correlation Analysis and Regression Analysis & Prediction Model. The level of the Awareness on Mobile Phone Hazardous Waste Management index (AMPHWM index) was high. The AMPHWM index of men was higher than women and significance difference (p<.05). The group of 13-14 years of age had AMPHWM index at the highest level. The samples of junior high school students had higher AMPHWM index than the group of senior high school students. The group of students who bought the mobile phone themselves had higher AMPHWM index than the others. The group of students belonging the mobile phone with 15000 baht had higher AMPHWM index than the low price. The group of students paying service charge monthly about 301-500 had higher AMPHWM index than the group paying more or less. The group of exposure to information had higher AMPHWM than no exposure to information group. Most of students received information from T.V.. The Awareness on Management of Mobile Phone Waste of the group of exposure to information and the group did not expose to information had correlation to the Behavior on Management of Mobile Phone Waste. The level of the Behavior on Mobile Phone Hazardous Waste Management index (BMPHWM index ) was average. The BMPHWM index of men was higher than women. The group of 13-14 years of age had higher than the others. The samples of junior high school students had higher BMPHWM index than the group of senior high school students. The group of students who bought the mobile phone themselves had higher BMPHWM index than the others. The group of students belonging the mobile phone with more 8001-15000 baht had higher BMPHWM index than the lower and higher price. The group of students paying service charge monthly about 301-500 had higher BMPHWM than the group paying more or less. The group of exposure to information had higher BMPHWM index than no exposure to information group. The group of students received information from internet or electric media had higher BMPHWM index than the group students who received the information from the others.

The objective of this research is to propose a new way to fabricate a composite material for future bone replacement development via growing apatite crystal on silk fibroin fiber. Apatite crystallization on silk fibroin fiber was prepared by precipitation reaction between Ca(NO3)2 solution and (NH4)2HPO4 solution adjusted pH by NH4OH solution. In this work Effect of solution concentration and initial pH values was investigated on apatite crystals. Chicken eggshells were used as calcium source by heating sufficiently powdered eggshells at 1300 °C for 4 h to acquire CaO powders made Ca(NO3)2 solution by dissolving in 65% HNO3 solution. Prepared Ca(NO3)2 solutions were adjusted concentration as 3 levels and were adjusted different pH values of 7 8 and 9 respectively. For processing of apatite crystallization silk fibroin fibers were immersed in Ca(NO3)2 solutions for 30 min. After that (NH4)2HPO4 solutions were added in silk fibroin fibers immersed in Ca(NO3)2 solutions. Reaction time was fixed about 1 min before cleaning to remove impurity precipitates on surface of silk fibroin fiber. Finally apatite crystallization on silk fibroin fibers occurred. The obtained result can conclude morphologies of apatite crystals on silk fibroin fibers was sheets sphere and flower. Solution concentrations and initial pH values directly influenced on Ca/P ratio of obtained apatite crystals by Ca/P ratio increases as increased solution concentrations or increased pH values. Finally research silk fibroin fibers were woven as two patterns of plain weave and twill weave and they were investigated Young’s modulus and tensile strength. The result indicates that Young’s modulus of silk fibroin fiber sheets woven as twill weave and as plain weave were about 616 MPa and 425 Mpa and tensile strengths of them weave were about 40 Mpa and 72 Mpa respectively. The optimum condition of growing apatite crystals on silk fibroin fibers was sample of CP19. Design of silk fibroin fiber with plain weave was an optimum pattern for future biomedical applicaions.

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 purposes of the research was to develop the system consulting for quality assurance Rajamangala University of Technology Phra Nakhon including found out the quality by the experts and the system users’ satisfaction. The research tools were as follows: 1) the system consulting for quality assurance Rajamangala University of Technology Phra Nakhon 2) quality evaluation form and 3) a questionnaire on users’ satisfaction. Tool for system development of this research were Microsoft FrontPage and Macromedia Flash Version 8.0. The research sampling group consisted of 30 the administers and staffs educational from assurance departments. The results of this research was found that the quality evaluated by experts in content towards the system consulting for quality assurance Rajamangala University of Technology Phra Nakhon was as a good level the average mean was as 4.15 and the standard deviation was as 0.63 in order words. The quality evaluated by experts in multimedia was 4.16 on the average or at a good level and the standard deviation was as 0.41 in order words. The users’ satisfaction on the system consulting for quality assurance Rajamangala University of Technology Phra Nakhon was 3.97 on the average or at a good level and the standard deviation was as 0.06. Therefore the system consulting for quality assurance Rajamangala University of Technology Phra Nakhon was able to be used properly.
