The purpose of this research was to develope the laboratory waste management and provide this knowledge to the students and the research assistants of Faculty of Pharmacy Mahidol University by using the methodology of participatory action research (PAR). This project was performed by training course and releasing the method of waste management by different medias. After the training the 80 participants have been assessed the knowledge using the Scoring Rubrics as a criterion for the evaluation. The result showed that the participants understood about the wastes storage systems the wastes categories the wastes labelling types the wastes containers drop points of wastes the useful of waste storaging the officers who responsible for the storage of waste in the laboratory in the percentage of 97 94 87 97 97 100 and 98 respectively which all passed the specified criteria. The summary of comments and suggestions were that the containers to collect the waste were not enough due to there were many varieties of solvents. This research enables the users to know how to dispose the wastes by differentiating the chemicals types and perform accurately which leading to the reduction of the amount of hazardous waste reduction the unknown waste the waste management from the laboratory become more systematic which will reduce the budgets and decreasing the risk to the health.

The research aimed to exploratory factor analysis of computer self-efficacy of undergraduate students at Department of Information Technology Faculty of Science and Technology Suan Sunandha Rajabhat University. The sample used in this study included 80 students who studied in level 3 in second semester of academic year 2012. The data collection tool is a questionnaire use a 5 rating scale. The finding revealed that the computer self-efficacy of undergraduate students was divided into 4 groups: group 1: Computer software and hardware consisted of 6 variables can be explain the computer self-efficacy 40.58%. Group 2 : Computer skills consisted of 3 variables can be explain the computer self-efficacy 11.19%. Group 3 : Data management consists of 2 variables can be explain the computer self-efficacy 9.50%. Group 4 Advanced Computer skills consists of 2 variables can be explain the computer self-efficacy 7.82%. which factors in 4 group will be able to explain the computer self-efficacy 69.08 %

To determine the impact of breakwater construction on fish assemblages larval and juvenile fishes were used to interpretation. The study was conducted in the inter-tidal zone constructed breakwater and natural sandy habitats of Pakmeng Beach at Sikao District Trang Province. The morphology of water bottom showed that differ between the front areas of breakwater construction and natural beach. The bottom profiles at in front of natural beach is seem to be deep immediately from shore and connect to a flat sand dune whereas in front of breakwater construction area was shallow and flatten. Fish assemblage data had showed the average number of larval and juvenile fishes no differ between the two habitats whereas the number of taxa of juvenile fishes was higher significantly in the inter-tidal zone of breakwater constructed area (Mann-Whitney U=11.5 p=0.017) Even though our study have revealed the application of fish assemblage data to asses the impact of constructed breakwater. Current study have limited on data collection not entire seasonal of larval and juvenile fishes abundance. Using our interpretations in other study sites is necessary to collected more frequency both beach morphological and fish assemblage changes.

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.

One important factor that makes the variations of electric current produced from solar cells (Ipv) is the variability of the weather conditions of the day. The one year experiment from January to December 2012 had been set up. The experiment of the comparison of the weather data satellite images and the different current (Ipv_d) was obtained from daily Ipv. The results illustrated that there were 4 major types of the relationship between the Ipv_d and weather conditions; 1) Low Ipv_d at around 2000 mA with low perturbations would correspond to the clear sky condition. 2) Perturbation of Ipv_d in some periods would correspond to the cloudy condition. 3) High perturbations of Ipv_d for all day long would relate to the rainy – cloudy condition. 4) High Ipv_d at around 4000 mA with low perturbations would relate to the cloudy condition all day long.
