Voltage drop is one of the power quality problems affecting power users. This happens due to the higher demand for electric power. Or a short circuit in the transmission system. This causes a voltage drop is one of the power quality problems affecting power users. This happens due to the higher demand for electric power. Or a short circuit in the transmission system. This results in drop in Solving of voltage drop problems in power distribution model with distributed generator were presented with MATLAB program by installing a generator in the distribution system. Therefore simulated a case study 5 case 1 simulation by not installing a generator at any bus case 2 simulation by installing a Generator at bus 1 case 3 Simulation by installing a Generator at bus 18 case 4 simulation by Generator installed at bus 33 and case 5 simulation by Generator installed at bus 13 17 21 31 to study the suitable location of generator installation to solve the problem of voltage drop.

The objective of this study is to observe the relationship between Budget Management and Effectiveness of private schools in Bangkok. The population and sample groups of this study include 691 schools in which 123 focused samples derived from determining samples’ sizes are according to Krejcie and Morgan’s Table. The data used in this study is provided by school administrators chief budget accountants and teachers. The employed study instrument used in collecting data is overall four-part questionnaire survey. Collected data is statistically analyzed by percentage arithmetic mean standard deviation correlation coefficient of Pearson and Multiple Regression Analysis The finding of this research reveals that 1)Private schools’ Budget Administration around Bangkok is general and in each aspect were at a high level : the highest arithmetic mean is account management aspect followed by budget allocation. 2) Private schools’ Effectiveness is general and in each aspect were at a high level : the highest arithmetic mean is teachers satisfaction aspect followed by the ability to adapt from internal and external factors respectively. 3)There is also a positive relationship between schools budget management and schools effectiveness with statistical significance at 0.01

The objective of this research was to study the antibacterial activity of 16 samples of indigo dyed fabrics that are produced and sold in Sakon Nakhon Province. Effect of moisture and pH of indigo dyed fabrics on bacterial growth were also determined. The result of the study shows inhibition of S. aureus TISTR 746 and E. coli TISTR 073 by agar diffusion plate test all samples could inhibit Saureus TISTR 746 (accounted as 100%) and only 9 samples could inhibit E. coli TISTR 073 (accounted as 56.25%). Whereas the study of antibacterial activity by AATCC test method 100-2004 at 24 hours was found that the natural indigo dyed fabrics code A3-1 could inhibit both bacterial strains in the highest level. The result also shows the effect of moisture and pH of indigo dyed fabrics on bacterial growth it was found that the increased humidity levels of indigo dyed fabrics have effect on the reduction of the inhibition efficacy of both strains. While indigo dyed fabric with pH 3.0 was found to inhibit most of the growth of both strains. In addition images obtained using a scanning electron microscope (SEM) could clearly confirm the property of indigo dyed fabric on inhibition of S. Aureus TISTR 746 and E. coli TISTR 073.

The purposes of this research were to develop and to test performance of mini heat pump dryer for slice banana. Drying chamber of 0.48×0.47×0.39 m3 was designed and it could contain three trays. The three trays had dimension of 0.33×0.409 m2. A blower with 174.6 W motor of air condition was modify and could adjust flow rates of three levels for air cycle system in dryer. The air system had bypass air at evaporator. The refrigerant of R-134a and four main parts were used in the heat pump system. The four main parts were a 497 W hermetic compressor a 1800 W condenser an expansion valve and a 1300 W evaporator. Experiments for test performance of the mini heat pump dryer used close loop air system an evaporator bypass air of 60 % a temperature of 60 oC and various flow rates of 0.117 0.128 and 0.140 m3/s. Slide bananas of 400-500 g had an initial moisture content of 244-281 %dry basis and were dried until final moisture content lower than 6.24±0.007 %dry basis. It was found that the flow rates of 0.117 0.128 and 0.140 m3/s had coefficients of performance (COPh) of 3.32±0.066 3.88±0.031 and 4.24±0.08 respectively and had specific moisture extraction rates (SMER) of 184.5±11.85 186.2±8.17 and 200.1±21.34 g/kWh respectively. The flow rate at 0.140 m3/s was the best condition because it had high specific moisture extraction rate.

Research on Restaurant Demand for Seniors in Bang Sue Dusit and Phra Nakhon Districts Bangkok The objective was to study consumer behavior of the elderly. Food demand for senior citizens in Bang Sue Dusit and Phra Nakhon districts Bangkok The population used in this study were 400 elderly people in Bang Sue Dusit and Bangkok areas. The survey instrument was a questionnaire. The statistics used were frequency frequency percentage mean standard deviation. Two-group mean difference test and One-way ANOVA Analysis of Variance. The results of the study found that most of the respondents were female. Age between 60 - 69 years marital status Most of them are working as government pensioners. and earn less than 10 000 baht. An analysis of the behavior of the elderlys restaurant use revealed that the elderlys behavior of using the restaurant when they are together with their family. The type of restaurant that the elderly use the most is national restaurant. The frequency of using the restaurant for the elderly most of the time. The elderly will go to the restaurant on Saturday - Sunday. The elderly tend to use the restaurant 2-3 people at a time. Access to restaurants more than 501 baht or more. Results of the analysis of restaurant needs for the elderly. Classified by service marketing mix it was found that the elderly had demand for restaurants classified by service marketing mix. Overall its at a high level. The elderly had the highest level of need for physical characteristics followed by personnel at the high level. and the price is at a high level respectively. The results of the hypothesis testing of restaurant demand for the elderly and demographic characteristics revealed that gender age and income were different. There are different restaurant needs for seniors. Analysis of 4Ps marketing strategy the shop must focus on producing fresh clean products and the food must be beneficial to the health of the elderly. and clear beverages suitable for the elderly in choosing to order food. Location the shop must have a convenient location for the elderly marketing promotion Organize promotional activities according to various festivals to meet the needs of the elderly. and clear beverages suitable for the elderly in choosing to order food.
