The side is able to perform the task correctly as assigned and the side has an understanding and can determine the guidelines for the operation. The side can perform the work completely and completely as assigned and the side can perform the work quickly and on time to a large extent.

his research work aimed to study the effects of the addition of sisal fiber and surface treatment by epoxy silane on the physical and thermal properties of polylactic acid (PLA). Specimens of PLA and unidirectional fiber-reinforced composite were processed by a compression molding machine and evaluated the physical and thermal properties by water absorption measurement and differential scanning calorimetry (DSC) analysis respectively. The result showed that water absorption tended to increase by adding sisal fiber whereas surface treatment of sisal fiber by epoxy silane improved water resistance of composites. The water absorption values at immersion time of 5 days were 0.89 1.13 and 1.26 % for PLA PLA/treated sisal fiber composite and PLA/untreated sisal fiber composite respectively. For thermal properties the addition of sisal fiber led to decreases in glass transition temperature and crystallinity. These were because the presence of continuous fiber might interfere with the crystallization of PLA. The surface treatment of continuous fiber with epoxy silane led to difficult crystallization. The good interfacial adhesion interrupted PLA alignment.

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

This research was aimed to study of the effect of dragging force on paper cone falling by using the high-speed video analysis technique. Four different sizes of paper cones ranged from 3.00-5.70 centimeter were used. The cones having the same mass of 12 g and falling from 2.50 meters height were recorded for 240 frames per second and then were analyzed using the Tracker Video Analysis software. The results showed that (1) all four different sizes of paper cones were not freely fall with the Earths gravity due to indirect proportion with time of theirs speeds. The terminal speed of two large cones having diameter of 5.00 and 5.70 centimeters were 4.42±0.03 and 3.97±0.04 meters per second respectively. Only 0.87% of these experimental values were different from the theoretical ones. (2) The theoretical trajectory of these cones falling using the terminal speed from the experimental agrees with the theoretical ones. (3) The experimental drag force showed a second order function of the paper cone’s speed. The evaluated drag force during terminal area is approximately equal to the cone weight. Thus this technique can help students and teachers to visualize simple physics phenomena and relate them to the physics principles learnt in the classroom

The objectives of this study were to study personal factors service quality and the decision to choose the service of savings cooperatives in Bangkok to study personal factors that affect the decision to choose the service of savings cooperative members in Bangkok and to study the quality of service that affects the decision to choose the service of savings cooperative members in Bangkok. The population was 1210043 savings cooperative members in Bangkok in 2019. The samples were randomly selected from the population by Purposive Sampling of 400 people. The sample size was determined according to Taro Yamane method. The data was analyzed using descriptive statistics such as frequency percentage mean and standard deviation. The inferential statistics were: independent sample T-test one-way ANOVA analysis Pearsons Correlation Coefficient and Multiple Regression Analysis. The study results showed that the overall service quality level of savings cooperatives in Bangkok was high. The aspects that the sample group thought was of the highest quality was the facilities and responses to member services. The most important factors affecting the decision to use the services of the sample group were human resource development and service development. The study hypothesis test showed that personal factors namely age and membership duration in a savings cooperative affected the decision to use the service of savings cooperative member in Bangkok at a significant level of 0.05. The cooperative members aged 26-35 years focused on service development less than those aged 46 years and over at the statistical significance of 0.05. The group of 16-year membership focused more onservice development than those at the group of 6-10 year membership and the group of 11-15 years of membership at a significant level of 0.05. The service quality factors on trustworthiness confidence and knowing and understanding service recipients had a positive influence on the decision to use the savings cooperative service on cooperative business development aspect at the significant level of 0.05. The service quality factors on trustworthiness confidence and knowing and understanding service recipients had a positive influence on the decision to use the savings cooperative service on human resource development aspect at the significant level of 0.05. The service quality factors on trustworthiness and knowing and understanding service recipients had a positive influence on the decision to use the savings cooperative service on service development aspect at the significant level of 0.05. The service quality factors on confidence and facilities had a positive influence on the decision to use the savings cooperative service on service area development aspect at the significant level of 0.05.
