The experiment was in a type of 4 experimental wells with the size of width x length x height was equal to 0.5x1x 0.5 meters including the experimental well which had plants of Colocasiaesculenta (L.)Schott PandanusamaryllifoliusRoxb and Canna indica Linn and the rest was the control well without any plants. The time period of Alternating 5 days flooding and 2 days drying Soil. The parameter studied included BOD value suspended solids Total KjeldahlNitrogen Total Phosphorus pH and Oil and Grease. The research result found that the experimental well which had Colocasiaesculenta (L.)Schott PandanusamaryllifoliusRoxb and Canna indica Linn had the effectiveness in wastewater treatment higher than the control well without any plants. After treatment with the control well without any plants the experimental which had plants of Colocasiaesculenta (L.)Schott PandanusamaryllifoliusRoxb and Canna indicaLinn with the romoval percentage of BOD value at 22.66 69.93 63.48 and 76.37 respectively.Suspended Solids at 22.66 69.93 63.48 and 76.37 respectively.TotalKjeldahl Nitrogen at 26.41 68.67 64.21 and 72.99 respectively.Total Phosphorus at 52.26 81.6975.73and79.88respectively.pHat6.42 6.556.64and 6.88 respectively.Oil and Grease at 62.08 78.75 76.47 and 80.39respectively.

This research intends to study the English language learning strategies of students in the faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon and to compare the learning strategies among gender three fields of study and English language achievement. The population group is 215 second-year Liberal Arts students in the second semester of the academic year 2016. The instrument was the Strategy Inventory for Language Learning (SILL) questionnaire. The obtained data were analyzed to find percentage mean and standard deviation. The study findings revealed that the overall use of English language learning strategies was at the medium level (=3.19). When considering each strategy the highly used learning strategy was compensation learning strategies (=3.46) and followed by affective learning strategies (=3.36) metacognitive strategies (=3.15) social strategies (=3.13) memory strategies (=3.03) and cognitive strategies (=3.01) respectively. The result also indicated that the learners’ fields of study and English language achievement significantly affected the overall learning strategies but gender did not show significant differences.

A Study of Factors Affecting Student’s Decision to Drop out School: A Case Study of Faculty of Industrial Textiles and Fashion Design Rajamangala University of Technology Phra Nakhon was an applied research. It was designed for analyzing the voice of customers in student studying management. The samples group was four department students in the Industrial Textiles and Fashion Design faculty as Garment Technology Textile Chemistry Technology Fashion and Design and Product design who retired during study and graduated in 2014 and 2015 academic year. The research results were used for improving the study efficiency and reducing the unexpected study. From the results shown the most problem was withdrawn registration especially in the first and the second year student. Garment technology department was the highest rate of retention after that Fashion and design Textile Chemistry Technology and Product design were respectively. The education satisfactions survey was found the moderate level for curriculum and lecturer as the mean 2.57 and 3.14 orderly. Additional the environmental satisfaction was low as 2.26 for the unexpected education students. In the other hands the graduated students had the greater satisfactions for the whole factors. The curriculum satisfied was good as 3.30 the lecturer was best as 3.67 and the environment was moderate as 2.95 correspondingly. From these results the Faculty of Industrial Textiles and Fashion Design were developed and pay attention in the subjects and lecturer in the first and second year education. The understanding of core study and the essential of each department was the significant factor for retaining and priding the student until they graduated in the Faculty of Industrial Textiles and Fashion Design.

The first purpose of this research is to study the using of personnel management system of Rajamagala University of Technology Phranakhon. Secondly the satisfaction in system using is suggested. The investigation and gathering information from university workers are done by questionnaire of satisfaction. The information is evaluated by using frequency percentage mean and standard deviation term. The reliability of two samples is tested by t-test using Alpha Coefficient of Cronbach and the reliability of more than two samples is tested by One Way Analysis of Variance. The results showed that the efficiency of using the personnel management system is the same as the system which is used in division of personnel management administration and division of general administration. The setting manual and log out of system which used in sub-system of each role are consistent with research hypothesis. The analysis of satisfaction of all workers between sexes (male and female) and between duties (support and academic staff) showed that the satisfaction in personnel management system is at high level.

The level of statistical significance was at .05 level and multiple comparison test was run by Scheffe. application. . The result of research found that the majority of students were male (54.8%) the students were studying in the first year (29.3%) Bangkok commercial campus (47%) the students whose parents were together (72.3%) the students whose families had more than 4 members (68.25%) the students whose total family incomes (baht/month) 30000-39999 baht (22.3%) the students lived in their house/relatives house (3.98%) by the highest average side was benefit that received from attending the activities (3.98%) an opinion of students about attending the activities held by RMUTP have the overall level in high (3.67%) The hypothesis testing revealed that Rajamangala University of Technology Phra Nakhon students’ opinions had significant difference at .05 level in terms of their academic year and faculty.
