This study was to 1) investigate the using behavior on the road accessories in the park and 2) analyze the design guideline for the product consistent with the use of leisure space in passive way 3) synthesize the design guideline to for the product consistent with the use of leisure space in passive way to response city life and 4) to find solutions to the problems of sustainable use of public space. The conclusion of the data analysis by using questionnaires from residents in the sample area found that; 1) Respondents were 130 men or 43.4% and 170 women or 56.6% 2) the highest average score was from 94 respondents age 31-40 years old or 31.4% 78 respondents age 21-30 years old or 26% 3) 116 respondents or 38.7% were company staffs with the highest score followed with 89 students or 29.7 and 4) 4 respondents or 8.89% who have live less than 20 years 14 respondents or 13.11% age 21-30 years old 12 respondents or 26.67% age 31-40 years old and 15 respondents or 33.33% for age 41 years old up 5) 98 respondents or 32.6% spend time in the park 1-2 times a week 94 respondents or 31.3% 6) 142 respondents or 47.3% for the reason of relaxing in the park- quiet and followed with easy to access 121 respondents or 40.3% and lastly 7) the activities in the park is relaxing 141 respondents or 47%.For design the research design from data analysis and experts. It shows that 1) the main structure is steel tube and nylon product and 2) concept design was from nest and cradle. The feature of the product is like the weaverbirdnest and the cradle gives personal area.

At present the electrical power system has growth and more complicate. Because of the development of the economics and society. An increasing the demand of power transmission line system would be resulted in the stability and reliability. The Flexible AC Transmission System devices: (FACTS) is the equipment which can control the flow of real power. In addition it can gladly encourage the stability and reliability of the power transmission line system. This research proposed the impact of placing power electronics device to increase stability and reliability of power system in order to study the impact of Flexible AC Transmission System devices: (FACTS) devices for the resulting to stability of power system. UPFC devices model which consisted of Static Synchronous Compensator and Static Synchronous Series Compensator that worked as independent voltage source for technique to proposed control the flow of real power and reactive power as well as voltage bus in power system. Testing Simulation power flow control of 5 buses by placing unified power flow control indicated the effective compensation of real power and reactive power in power system.

This research presents the studying of short circuit in distribution system that affect to critical equipment voltage sag and overvoltage while short circuit event. Lead into the quality of electric user. Effect on economics damaged Distribution system voltage level 22kV of The Provincial Electricity Authority. It is the analysis model by computer program. The event of short circuit set in a many distribution systems. The analysis result Magnitude of voltage while short circuit bring to assessment voltage sag and overvoltage from average voltage of the repeat event. Then set boundary of voltage at load point in a many. The experiment shows the problem of the quality of electric be affect to critical equipment less than load point close connection with substation.

This research aims to increasing efficiency in production and eliminate the problem of insufficient production capacity with respect to customer demand for electrical appliance factory by applying the line balancing method. Thus the study then developed two problem-solving approaches. The first approach is a method by which a firm applies the line balancing concept and ECRS technique (Eliminate Combine Rearrange and Simplify). On the contrary the second approach is required an investment in testing machine with value of 1000000 baht in order to support sufficient production capacity to meet customer demand. Also ECRS method is used to accomplish this process. Based on the results the first approach provided the production line efficiency improvement representing of 82.59% and reduced the labor cost of 277220 baht per year. However the loss of commercial opportunity has remained the same of 6336000 baht per year. Accordingly the second approach demonstrated of 92.11% of the production line efficiency improvement and the labor cost reduction valued of 277220 baht per year. As we expected the second approach satisfied production efficiency by eliminating the loss of commercial opportunity with value of 6336000 baht per year delivering a return of investment within two months.
