The preparation of silver fiber with electrospinning process was a principle to impulse the iron within the polymer solution. The polymer solution jetted onto the ground collector in nonwoven form when the electric charge was higher than the polymer surface tension. This research had 3 key factors consideration that were electric power supply polymer concentration and length between needle tip and aluminum ground collector. The electric voltage was 6 9 12 15 and 18 kilovolt the ratio of Ag : polymer solution (%wt) was 1:10 1:20 and 1:30 and the length between needle tip and aluminum foil collector was 6 7 8 9 and 10 centimeter respectively. The fibers obtained were investigated and compared to the fiber morphology by Scanning Electron Microscope and the anti-bacteria test via AATCC test method 100-1999 (Quantitative) and 147-1998 (Quality). The optimal electrospinning condition was 18 kilovolt the ratio of Ag : PVA (%wt) was 1:20 at length 7 centimeter. The fibers were continuous average diameter as 183.3 nanometer and available to against bacteria.

The objective of this research was to study the quality of tourism services of Bangnumphung Floating Market based on the service marketing theory which involved product price place promotion physical evidence people and process. The research instrument was questionnaire. The 400 subjects were selected by convenience sampling. The results demonstrated that the opinion of tourists on tourism service quality of Bangnamphung Floating Market was in a good level wheeas the quality of promotion was a neutral level in every area except for the additional events which were in a good level. The majority of the respondents preferred natural tourist attractions. The source of information about the Floating Market was acquired through friends family and relatives. Convenience is the reason why the respondents wanted to visit such place. The majority of the respondents had used cars to the floating market and they were also accompanied by their family : Parents children siblings and relatives. The visit frequency was twice to three times. The tourists spent 2-3 hour travel per visit. Tourists expenditure was 501-700 baht. The activity was to have meat dish and sweet food.

In the current practice cotton fabric is predominantly dyed with direct dyes in the presence of a considerable amount of electrolyte (Salt) to reduce negative charge on fiber surface. Thus the high concentration (40-100 g/l) of electrolyte required in cotton fabric dyeing may pose additional effluent problem and waste water treatment costs. The use of polycationic agent to modify the dyeing behaviour of direct dyes on cotton fabric is investigated. Normally polycationic agent had been treated on dyed fabric to improve fastness properties. The comparison of untreated and pretreated cotton fabric was found that the polycationic agent offers the potential for different dyeing patterning possibilities. The dyes was fixed on the fiber by ionic force. So color strength and exhaustion of pretreated fabric was better than untreated fabric and increased in fastness properties even when dyeing had been carried out in the absence of electrolyte. The purpose of the present work was to determine whether the pretreatment of cotton fabric with polycationic agent could enhance the dyeability of the fiber with direct dyes under appropriate condition such as assuming a positive charge on fiber which permitted “electrolyte-free” dyeing after modification without drain and helped reduce dyeing cost.

Rajamangala University of Technology Phra Nakhon Technology Service section Institute of Research and Development with collaboration of Department of Tools and dye Technology Faculty of Engineering produced the prosthesis for the disabled since 2000. Rajamangala University of Technology Phra Nakhon has allocated annual budget for the ongoing operations of more than 350000 baht per year and has provided materials tools and components including the use of machine tools and university personnel for designing innovation. testing and manufacturing and delivering prosthetic equipments to government agencies that serve hopeless people who have no chance to servive and help the disabled who lost their arms or legs to live a normal life independently and would not be burden to the society.

This research aim to improve a combustion system of boiler within increase combustion efficiency and use all out of the energy. The large boilers were used in the industrial factories which consume a lot of energy for production. By oil and gas fuel will be increasing costs everyday cause many factories interested in energy saving with any method technical engineering specifically for production costs and environment effect decreasing. This researching was installed and program was invented in the industrial factory. This industry factory consumed cogeneration energy for fabric dying. The efficiency before installing the software is measured about 65.85 - 71.98% which heat in exhaust gas about 20% of overall energy is filled in the system. After installing heat loss in the system has been fallen until remain about 5 - 12% and efficiency of heat in system has been reached a peak of 80 - 85%.
