This independent study aimed to 1) study the level of the work satisfaction and the organization commitment of the employees in the Faculty of engineering Rajamangala University of technology Phra Nakhon; 2) study the relationship between the work satisfaction and the organization commitment of the employees in the Faculty of engineering Rajamangala University of technology Phra Nakhon The samples used in this study were 154 Staffs who worked at The Faculty of Engineering Rajamangala University of Technology Phra Nakhon. The study instrument was the questionnaire used to collect data. The results showed that 1) the level of the work satisfaction and the organization commitment of the employees was positively at a high level. 2) The relationship between the work satisfaction and the organization commitment of the employees was found to be significant at the .01 level.

This research aims to study the removal of color and chemical oxygen demand (COD) from the corrugated industry with the ozonnation. The use of ozone with capacity in the range of 24.5-59.0 mg per hr. By studying the factors and conditions that are suitable for the treatment of COD in wastewater which consists of the following factors.pH 4 7 and 10 ozone exposure period of 120 minutes and initial COD concentration of 200-720 mg per liter. Have conducted experiments using real wastewater from the plant mentioned above affect the performance of the reactor COD with the ozonnation. At pH 4 to provide maximum efficiency in the treatment of COD compared to pH 7 and pH 10. In addition the concentration of the starting COD higher performance of the reactor is reduced. The results suggest that the treated of COD up to 81.6 percent. COD in wastewater treatment is started at 200 mg per liter. When the concentration of COD in wastewater from the 450 mg and 720 mg per liter. Found that the performance of the reactor the COD decreased to 71.2 and 64.4 percent respectively. For effective treatment of wastewater with turbidity and color ozone process Nation to be aligned with the performance of the reactor COD. The performance of the reactor is decreased when the concentration of the starting COD higher

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

Extraction of plastic and aluminum foil from beverage cartons with biological processes is one environmentally friendly approach that is appropriated for paper recycling. The other remained parts including plastic and foils can thus be utilized. This research aimed to improve the capability in digestion of cellulose paper of microbes isolated and screen from fruit durian and jackfruit in degradation of beverage cartons. In the small scale processes reducing sugar indicating the efficiency of the degradation process of the boxes was released from the hydrolysis of paper and determined by biochemical method of Benedict test. The controls of alkali and water immersion were utilized for these experiments. In the medium and large scale digestion processes the results showed that microorganisms helped separate sheet papers from the plastic and aluminum foils shortly in 14 days after boiling in water for 10 min. The bacteria digestion were well adapted within 14 days and prolonged their high degradability until 28 days. They could degrade the cellulose components better than the fungi with the separation efficiency of 70 percent and 66 percent respectively. Therefore from overall the biodegradation process of microorganisms have a high potential in digestion of various paper products for recycling and can be applied in industrial applications.

The purposes of this research were to investigate (1) the image factors affecting parents’ loyalty on the use of BUB in da POOL swimming center for babies and toddlers and (2) services factors affecting parents’ loyalty on the use of BUB in da POOL swimming center for babies and toddlers. Data were collected through the questionnaire responded by 174 parents of the children and analyzed by the frequency percentage mean and standard deviation to analyze information on image factors and service quality that affected the parental loyalty of children using the BUB in da POOL Infant and Child Training Center. Pearson Product Moment Correlation Pearsons Product Moment Correlation Coefficient and Multiple Regression Analysis were applied to analyze the data. The research revealed that the image influenced the loyalty of children’s parents using BUB in da POOL business with the branding image value of 0.422 and the corporate image of 0.330 influencing the parental loyalty of children using the BUB in da POOL at the highest level. While branding image factor did not affect the parental loyalty of the child using the center. The quality factor influenced the parental loyalty of children using the BUB in da POOL Center at 0.422 of with the reliability of 0.184 and the parents’ attention to the ง service quality was 0.234 which influenced the parental loyalty. Responding to the parents of children using the service had the greatest impact on the parental loyalty while the factor regarding its compactness of the services and trustworthiness trust did not affect the loyalty of parents of children who used the center for teaching babies BUB in da POOL.
