Dye effluent treatment with photocatalytic technique and adsorption process had an objective for studying the combination process between Titanium dioxide and activated carbon from dye effluent. The dye effluents were prepared from the direct dye reactive dye acid dye disperse dye and basic dye. The effluent dyes from the completely dyeing process at 1 % owf initially. All of dye structures were azo. From the study direct dye and reactive were successfully using combination process between photocatalytic technique and adsorption process whereas disperse dye favored in adsorption process. However acid dye and basic were ignored in this experiment cause of they were a bit of dye concentration in their effluent. The optimum condition for direct dye was 10g/l Titanium dioxide for 6 hours and 5 g/l activated carbon for 6 hours continuously. Reactive dye was performed in continuous condition as 10g/l Titanium dioxide for 6 hours and 10 g/l activated carbon for 6 hours. Disperse dye was the particular process in adsorption by activated carbon 15 g/l for 4 hours. It was summarized that the treatment of photocatalytic technique and adsorption process were upon on the type of dye.

This survey research was to identify need to participate in recreation activities of Rajamangala Univeristy of Technology Phra Nakhon students. Three hundred ninety first year through fourth year students from 9 different faculties. Multistage random sampling was used for the sample’s representation from the population. A standard questionnaire was used for testing this study purpose. This three sections questionnaire includes general information regarding subjects’ gender age year of study area of study student income to average per month for students and so on. The main 35 items rating scale type questionnaire was to identify types and need of activities from the university. The last session is a 4 items open-ended question asking for students’ recommendations. Frequency and percentage were used for data analysis. The statistical analysis revealed that male and female students moderately need university participating service in management and need highest on university service personnel. Male students however moderately need on facilities and equipments while female student do highest. On the participation need of recreation activity by class levels analysis only first year student’s highest need the rest of every year students moderately do. Students from first year to third year moderately need recreation service on management while forth year students and third year students from 2 years program highly need this service. In addition forth year students from 2 years program showed highest need to this service. However first to third year students moderately need on personal service only first and second year students moderately need this service. The second and forth year student and students from 2 year program were highly need this service. Lastly first year student highly need service on facilities and equipments while third year students moderately need this service. The rest of student class levels do need this service highest. By the area of study student taken analysis both science and social science areas students moderately need university recreational service. They however highly need on personal service. Students in the area of science moderately need service on facilities and equipments while social science student’s highest need this service.

The aim of this study was to examine an effect of self-control on self-discipline of student at Rajamangala University of Technology Phra Nakhon. Study participants were first year business administration students from 5 different classes during 2009 academic year (N = 194) with 51 males and 143 females. During the 7- week experiment students were asked to remind and report themselves regarding their behavior during Monday Wednesday and Friday. Data from questionnaire developed by researcher with r = 0.79 were analyzed with frequency percentages and means of percentages and reported as follow: 1) Student discipline behavior tended to change significantly after 7 weeks of experiment. 2) Six most behaviors occurred during the experiment were follow instructor’s suggestions and guidelines (96.9%) full class attendance and thinking of other rather than themselves (96.5%) instructor expectations (95.9%) being in classes in time (93.5%) and class attention and commitment (92.0%) respectively. On the opposite six least behaviors occurred during 7 weeks experiment are polite conversation (70.1%) using crossover bridge (79.8%) learning and understanding in classes and polite manner (82.2%) proper dress (86.7%) showing respect to parents before leaving and returning their houses (90.8%).

The purposes of this research are 1) to create computer multimedia through the Internet teaching tool for lighting for broadcasting course (undergraduate level) 2) to develop and to find out quality the create computer multimedia through the Internet teaching tool for lighting for broadcasting course (undergraduate level) and to achieve efficiency according to a set of 90/90 criterion. The samples for this study were 48 second year students of Bachelor of Technology Program in Radio and Television Broadcasting Technology studying this course in the first semester of 2011 academic year at Rajamangala University of Technology Phra Nakhon. The samples were selected by simple random sampling. The research tools used are the computer multimedia through the Internet an achievement test evaluation forms for quality assessment. Statistics used for analyzing the data were percentage and mean. The results of the study revealed that the computer multimedia instruction through the Internet was ranked as a very good level by content experts and as a very good level by educational technology experts and had its efficiency of 94.80/96.60 it was higher than criteria set 90/90

This research aimed to investigate perception attitude and behavior ofRajamangala University of Technology Phra Nakhon undergraduate students on 3Dpolicy - based activity Participation and the relations among perception attitude and behavior. 3D aspects include Decency Democracy and Drug-free. The data werecollected through 400 RMUTP undergraduate students from nine faculties in 2010.Data analysis employed frequency percentage mean ( ) standard deviation (s.d.).Statistics used for hypothesis testing included t-Test; to compare between two variables F-Test and One-way ANOVA; to compare more than two variables and Pearson Product Moment Correlation Coefficient. The results of study found that RMUTP students perceived news releases on 3 D policy of the university at the average level. In the meantime their overall attitude towards 3D policy campaign was rated in average level. The attitude towards Decency was at high level and Democracy and Drug-free were considered average. The student participation in 3D –based activities was rated at high level when considered by individual and overall aspect. Hypothesis testing resulted as follows: 1. Students with different gender had different perception of 3D policy with a statistical significance at .05. However there were no significant differences at .05 among students from different faculty. 2. Students with different gender and faculty had different attitude towards 3D policy with a statistical significance at .05 3. The participation behavior on 3D-based activities of students with different gender and faculty was different. 4. The perception of 3D policy new releases had a positive correlation with 3D- based activities participation behavior. 5. Attitude towards 3D policy of the university had a positive correlation with 3D- based activities participation behavior.
