Nowadays increasing water pollution has put significant pressure on water resources. Natural organic matter and organic micro-pollutants have been found in potentially harmful concentrations in numerous water sources. Phthalate plasticizers are also micro-pollutants of concern; Di- (2-Ethylhexyl) phthalate (DEHP) is one of the most frequently observed plasticizers in the environment as well as one of the most persistent. The maximum permissible levels of these compounds in drinking water and wastewater discharged to the environment are set at low concentrations. In this research water samples were collected from the New Bang Kaen Canal in Bangkok Thailand (13°4906.1N 100°3042.4E) which receives wastewater from human activities and contains impurities in the water. Several common treatment technologies currently used to remove inorganic and organic contaminants from natural water supplies address serious environmental problems. Properly selected microfiltration membrane processes are elements of effective systems for water purification. Polymeric membranes are of primary interest for membrane separation techniques because they are both practical and effective. However pretreatment before using a microfiltration membrane is necessary for suspended solids reduction. This research used two types of polymeric membranes namely cellulose acetate membrane (CA) and polyvinylidene difluoride membrane (PVDF) and covers the most applicable requirements regarding pretreatment of the water intake. The performance of polymeric membranes for water treatment was also investigated. The water quality of the New Bang Kaen Canal was assessed in terms of turbidity SS and COD. This research has the potential to contribute to the monitoring of water quality in the New Bang Kaen Canal. Water quality monitoring is a fundamental tool for water resources management. The performance of polymeric microfiltration membranes was effective for water and wastewater purification in terms of solids organic substances and micro-pollutant i.e. DEHP compounds. Nevertheless the further development of polymeric membranes regarding fouling on the membrane surface and within pores needs to be improved to increase membrane performance and ameliorate the limitations of microfiltration polymeric membranes.

Objectives of this research were 1) to study the environment of coopertive education program of the Faculty of Science and Technology Rajamangala University of Technology Phra Nakorn and 2) to study the achievement of this cooperative education program towards the development of graduates competency in the first semester of academic year 2013. Three sampling groups were from educational institutes enterprises and students. The number was 240 in total. Tools used in the research was a questionnaire opened and closed form number 4 sets were 1) questionnaire for coordinator or cooperative education officer advisor and lecturers 2) questionnaire for the executives coordinators or heads of human resources 3) questionnaire for employees consultant 4) questionnaire for cooperative education students. Performance analysis of cooperative education in the part of educational standard and the operation of science and technology using the content analysis method to comparing their content to the standard of Thai Association for Cooperative Education. To study satisfaction by using application program for statistical analysis such as frequency percentage mean standard deviation of mean values and descriptive discussion. The overall findings form this study showed that every relevant had high satisfaction with the management of the Cooperative Education Program of the Faculty of Science and Technology Rajamangala University of Technology Phra Nakorn.

The purpose of this study was to Evaluation of Curriculum for the Bachelor of Science Program in Computer Technology of Rajamangala University of Technology Phra Nakhon. The CIPP Model was used as evaluated model. The samples in this research were 125 undergraduates 14 Instructors 17 graduates and 11 employers of graduates. The 4 questionnaires of rating scales was used as the research instrument. Percentage mean standard deviation were statistical method to analyze data. The results were as follows: 1. The samples agreed with the Context Evaluation in the aspect of curriculum objectives curriculum structure curriculum content were in moderate levels. 2. The samples agreed with the Input Evaluation in the aspect of Characteristics of undergraduates and Characteristics of instructors were in high levels supporting education was in moderate levels. 3.The samples agreed with the Process Evaluation in the aspect of curriculum Management. teaching Management experience training were in high levels . 4 . The sample’s satisfaction towards Input Evaluation in the aspect of professional knowledge and Professional Characteristics were in moderate levels Ethics was in high levels .
