The objective of this research was to study the investors’ investment volumes affecting the Price change of the ETF SET 50 mutual fund in the Stock Exchange of Thailand. This research was the Quantitative Research. The descriptive statistics was used to test the preliminary data and used the Multiple Regression Analysis of the Inferential statistics to test the hypothesis and used Pearson Correlation to find the relationship between independent variables by using the daily data of the past five years start from January 1 2012 to December 31 2016. The results of the study found that the investment volumes of domestic institutional investors’ portfolio account of foreign companies and general investors affected the Price change of the ETF SET 50 mutual fund and the SET 50 stock price index in the Stock Exchange of Thailand at the 0.05 significant levels. The SET 50 stock price index was highly and positively related to ETF SET 50 mutual fund price change in the Stock Exchange of Thailand at the 0.01 level of statistical significance

This research presents a study of the compressive strength tensile strength flexural strength and water absorption of Cellular Lightweight Concrete containing fine rice hush-bark ash. Portland cement (CT) is partially replaced with pozzolans 20 30 and 40% by weight of the cementitious materials. The results show that the compressive strength tensile strength flexural strength and low water absorption of Cellular Lightweight Concrete improves substantially with partial replacement of Portland cement with rice hush-bark ash. Cellular Lightweight Concrete mix cement containing 20 and 30% of pozzolans can be used to make cementitious materials

The objectives of this special project were to product travel documentary of the National Museum in Suphan Buri Province and study of the satisfaction of thevisitors from 200 tourisms by using the questionnaire. The statistics to analyze data was frequency percentage average and standard deviation (S.D.) The result shown that the tourisms had high levels of satisfaction to the travel documentary of National Museum Suphan Buri Province.

The research purposes were to analyze and search for wastes in the planning process and transportation of the automobile parts of a transport company in Samut Prakan using Makigami Lean and ECRS Techniques. The informants used in this study were the support staff working the planning process and automobile part transportation for the car assembly factory in the industrial estate Rayong Eastern Seaboard. Six employees from different work units took part in the in-depth interview as the research tool for the data collection. Statistics used in the data analysis including percentage and workflow analysis with related management tools. The study indicated that searching for the waste in the technical planning process with Makigami Lean and ECRS Techniques could help reduce the work time for 1060 minutes in each step.

This research presents a study of the compressive strength flexural strength coefficient of permeability and superplasticizer requriment of Porous Concrete containing fine fly. Portland cement (CT) is partially replaced with pozzolans 0 20 30 and 40% by weight of the cementitious materials. The results show that the high compressive strength flexural strength and low total void ratio of Porous Concrete improves substantially with partial replacement of Portland cement with fly ash. Porous Concrete mix cement containing 20 and 30% of fly ash can be used to make cementitious materials. In addition the use of fly ash produces Porous Concrete mix with good compressive strength flexural strength total void ratio and coefficient of permeability.
