Tha Chin River is important to Samchuk Suphanburi province because the water can uses for urban agricultural tourism and industrial purpose. The increasing of population in Samchuk causes increasing of a demand of the water and a release of wastewater. Therefore the water quality of Tha Chin River was analyzed in flowing through Samchuk area in this research. The water sample was collected from seven ports area including two ports of urban area two ports of agricultural areas two ports of industrial areas and another port of tourism area. The water sample was monthly analyzed in various parameters including temperature in range 30-34 oC turbidity in range 28-59 cm pH in range 7.08-7.44 conductivity in range 19-23 s/cm dissolved oxygen in range 2.4-5.8 mg/L and biochemical oxygen demand (BOD) in range 2.0-8.4 mg/L depending on the seasons. In March exhibits the best water quality of Tha Chin River. In addition the water quality of Tha Chin River decreases from agricultural areas urban areas industrial areas to tourism area respectively. However the Tha chin river could be classified as class 1-3 which can be used for tap water fishery marine sport and agriculture.

The objective of this research was to evaluate the antioxidant and glucosidase inhibitory activities of 9 fresh and dried local vegetables extract from Kong Ra District Phatthalung Province such as Barringtonia acutangula (L.) Gaertn. Archidendron jirinaga Nielsen Scientific name: in process (Neang-rok: local name) Oroxylum indicum (L.) Kurz Ficus semicordata J.E.Smith Ficus oligodon Mig Ficus sp. Ficus obpyramidata King and Ficus fistulosa Reinw. The antioxidant activities were determined by DPPH radical scavenging. Results indicated that dried crude extract of Oroxylum indicum (L.) Kurz exhibited the highest DPPH radical scavenging activity at the final concentration of 5 mg/ml revealed the DPPH activity as 92.25%. Moreover the extracts were studied for their glucosidase inhibitory activities compare with authentic drug Acarbose Results indicated that dried crude extract of Ficus sp. exhibited the highest inhibitory activity revealed the inhibition activity as 85.46%. Thus these local vegetable might be possible new sources of glucosidase inhibition and antioxidants so there are suitable for use as functional food in the future.

This research presents the development of food exchange list program for individual person by using local search technique. Controlling conditions of the research the nutrients calculated of carbohydrate protein and fat must be less than 3 grams/day and 30 Kcal/day for energy has also been controlled. All development has been done on laptop computer. The results show that the averaged search time and the averaged search iteration are 2.8176 seconds and 2484 iterations respectively. The variations of carbohydrate protein and fat are –0.2683 +0.015 –0.6 grams respectively. The proposed local search technique can reduce the time of calculate up to 1278 times per case study when compared with training people.

The purposes of the study were to study the need competency and to develop the competency in information and communications technologies of teachers. The samples were 363 teachers of Rajamangala University of Technology Isan and 70 trainees of experimental group. There were 4 stages of methodology: 1) Study the basic information in order to analyze the need 2) Study the competency of ICT to analyze 3 parts of competency which were knowledge skills and features needed 3) Development preparation and 4) Training course development. The Tools were the questionnaire the achievement assessments of pre and post trainings and the evaluation of the training. The results revealed as follows: The need in information and communication technologies of teachers in 9 aspects was at the high level. The teachers training achievement is significantly different at the level of 0.05. After training the achievement is higher than before regarding the training course expectation teachers are satisfied with this workshop training at the high level. For the suggestion it should be follow-up continuously after training.

This research is a qualitative research concerning phenomenology study which aims at the meanings of the opinions of those who have experienced the public relations of Rajamangala University of Technology Phra Nakhon (RMUTP) lecturers and international affairs officers in immigration procedures (visa extension and doing the-90 day report). The objectives of this research are to study (1) types (2) methods and (3) capabilities of public relations of RMUTP lecturers and international affairs division for the international students who are in this case Chinese students of Language and Applied Thai program Faculty ofLiberal Arts Rajamangala University of Technology Phra Nakhon. The samples of this research are (1) student advisors (2) lecturers of Language and Applied Thai program (3) international affairs officers and (4) Chinese students of Nanning College for Vocational Technology (NCVT) who are studying Language and Applied Thai program Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. The researchers use in-depth interview and observation by participating procedures of public relations. This research started from October 2013 to October 2014. The researchers collected data 3 hours per day and 3 days per week within 53 weeks.
