The research project on The potential of Siphonodon celastrineus Griff traditional medicinal plants of Thailand for treatment from local wisdom knowledge lead to the development of sustainable use with the objective of studying the botanical phytochemical and biological activity of the Siphonodon celastrineus to create confidence in the use of S. celastrineus in herbal medicine by using the bark leaves and fruit of the S. celastrineus to extract with 3 types of solvents. Each of hexane ethyl acetate and methanol respectively from low to high polarity. All nine extracts will be extracted. Preliminary examinations for phytochemistry Antioxidant activity by DPPH radical scavenging assay and quantitative determination of phenolic compounds by Folin-Ciocalteu method and antimicrobial activity were tested. The research found that. 1. The extract of the results of the methanol layer of the S.celastrineus shows a reduction in the amount of 11-diphenol-2-picrylhydrazyl (DPPH) had the highest EC50 equal to 31 mg/ml. The amount of phenol compounds found that the extracts from the methanol extract of S. celastrineus contain the amount of phenol. The highest concentration of 95.23 mg GAE / g dw 2. Extract from the bark of the S. celastrineus with methanol showed the best inhibition of the growth of Vibrio paraheamolyticus with the MIC value of 15.60 mg/ml. The extracts of the S. celastrineus leaf extracts with hexane showed the best inhibition of the growth of Vibrio cholerae with the MIC value equal to 31.25 mg/ml and leaf extracts with ethyl acetate showed the best inhibitory effect on the growth of Vibrio cholerae with a MIC value of 31.25 mg/ml and the extract of the fruit with ethyl acetate to inhibit the growth of Vibrio paraheamolyticus most with MIC equal to 15.60 mg/ml.

The study aims to study the change leadership that affects the organizational culture and work efficiency of the staffs at the operational level and to study the good governance principles that affect the organizational culture and work efficiency of operational staffs at Commercial Concrete Production Business Unit. The population used in the study is 200 operating staffs at Commercial Concrete Production Business Unit using questionnaires for data collection. The data analysis is conducted using descriptive statistics and inferential statistics. The result indicates that change leadership affects organizational culture of operational staffs with statistical significance at 0.05 level. It can predict the organizational culture of operational staffs at 16.30 percent. Good governance principles affect the organizational culture of operational staffs with statistical significance at the level of 0.05. It can predict the organizational culture of operational staffs at 29.50 percent. Change leadership affects the operation efficiency of operational staffs with statistical significance at the level of 0.05. It can predict the work efficiency of operational staffs at 13.80 percent and good governance principles affect the work efficiency of operational staffs with statistical significance at the level of 0.05. It can predict the work efficiency of operational staffs at 28.70 percent.

14 samples of TSP and PMwere collected within the area of Amphoe Muang Pathumthani from 7 stations at Tambon Bang Prok Bang Duea Bang Khu Wat Bang Kradee Lak Hok Bang Changand and Kra Sang during February to March 2013 in order to evaluate the concentration of dust and lead concentration level by using ICP-OES. The result of this study shows the TSP ranging 0.03 - 0.32 mg/mmg/mμg/maverage of 0.04 ± 0.06 μg/mμg/m0.05 ± 0.07 μg/m10 3 and the average of 0.12 ± 0.10 3 . The concentration of PM10 is in the range of 0.06 – 0.21 mg/m3 average of 0.13 ± 0.06 mg/m3. Of the determination of lead in TSP concentration of lead found in the range of 0.01 – 0.18 3 3 while lead in PM10 found in the range of 0.01 – 0.21 3 average of 3. Assessment of the public health risk is found contamination of lead in the atmosphere of Amphoe Muang Pathumthani levels ranged from less dangerous except area Bang Prok is worth the risk is moderate danger.

Abstract The objective is to analyze Klong Prem Prachakorn water quality and its water management. A total of 10 parameters include pH water temperature turbidity dissolved oxygen (DO) biological oxygen demand (BOD) chemical oxygen demand (COD) suspended solid (SS) total dissolve solid (TDS) and coliform bacteria were measured. Water samples were taken from 3 sampling points along the length of the canal between Bang Khen train station intersection and Wat Samian Nari intersection with a total distance of 1.3 kilometers. Samplings were done weekly for 5 weeks started from 12th December 2013 to 15th January 2014. The results from weekly monitoring of Klong Prem Prachakorn’s water quality show that the values of each parameters being monitored are within the range of the surface water quality standards. Howeverthe reporting values may show weekly fluctuation which may be resulting from relating environmental factors such as changing temperature the canal’s water volume and level (may results from the operation of the floodgate by the Department of Drainage and Sewerage). Nevertheless the values show that the canal water is clean for surface water according to type 4 water quality and can be used inindustrial sector. This study on Klong Prem Prachakorn’s environmental condition has provided a piece of knowledge that was appliedfor environmental problems’ corrective concepts and guidelines. Furthermore knowledge and information gathered in this study together with the use of a Geographical Information System (GIS) can be applied for ecological conservation studies of the areas. This study contributes to an existing knowledge and understanding of Klong Prem Prachakorn’s water quality problems and can be used to support water quality improvement campaign
