In this study water quality standard of bottled drinking water distributed in Ang Thong Province was investigated. The results showed that clear plastic bottled drinking water presented completely label information and MFD./EXP. clearly appearance and odourless presented in all samples while Total Dissolved Solid (TDS) of tested clear plastic bottled drinking water samples were in a range of 1±0.00 to 277±0.00 mg/L. Coliform bacteria and fecal coliform bacteria of all tested water samples were less than 2.2 MPN/100 mL and E. coli and total heterotrophic bacteria were not found in all samples. pH values of 18 tested samples were less than 6.5 (60.00%) plastic bottled drinking water samples. Tested opaque plastic bottled drinking water samples showed completely label information and MFD./EXP. clearly appearance and odourless found in all samples while TDS of tested opaque plastic bottled drinking water samples were in a range of 12±0.00 to 13±0.00 mg/L. Coliform bacteria and fecal coliform bacteria of tested water samples were less than 2.2 MPN/100 mL and E. coli and total heterotrophic bacteria were not found in all samples. pH values of 3 tested samples were less than 6.5 (100.00%). Indeed assessment of both types of bottled drinking water samples distributed in Ang Thong Province Thailand based on 6 qualities assessment of standard for drinking water in sealed container set by Ministry of Public Health of Thailand revealed that the tested clear and opaque plastic bottled drinking water samples met the standard for 40.00% and 0% based on pH respectively.

ปัจจัยที่มีอิทธิพลต่อความผันผวนราคาของ SET50 Index Futures ในตลาดตราสารอนุพันธ์แห่งประเทศไทย ระหว่างปี พ.ศ. 2554-2558
ปัจจัยที่มีอิทธิพลต่อความผันผวนราคาของ SET50 Index Futures ในตลาดตราสารอนุพันธ์แห่งประเทศไทย ระหว่างปี พ.ศ. 2554-2558

This study examined Factors Affecting Price’s Fluctuation of the SET50 Index Futures in Thailand Derivative Market during the Year 2011 – 2015. The objective was to study all of the factors which was affecting SET50 Index Futures’s fluctuation. According to daily closing price data of SET50 Index Future used for computing continuous return the period before the maturity and the volume of SET50 Index Futures were calculated the fluctuation by using GARCH (11). The results show that the data and fluctuation in the past affected the data and fluctuation in the present by the same direction considerated by the coefficient in ARCH and GARCH term of GARCH Model (11). The period before the maturity affected the return rate by the opposite direction which means the return rates had much more fluctuation when the period of time closed to the contract maturity. It showed that the coefficient of the period before the maturity was quite less than the one of ARCH and GARCH. Therefore the fluctuation of return rate in the present was possibly depended on data and the period of fluctuation in the past more than the period before the maturity. The remainder of the study can give information to the investors that they should be concerned not only about data and fluctuation in the past but the period before the maturity of SET50 index futures which may affect the forecast of SET50 index futures price for Hedge management. Thailand Future Exchange should be considered to adjust proper risk margin inaccordance with fluctuation rate in a period of time.

The effect of inlet temperature on the solidification of tubular Ice
The effect of inlet temperature on the solidification of tubular Ice

This study was aimed to investigate experimental study of the parameters affecting the amount of tubular ice. Significant studied parameters were inlet water temperature. Thickness tendency was increasingly according to time. The thickness of the tubular ice varies with the square root of time according to the theory. At the beginning of the process thickness increased quite fast and decelerated at the end of the production process. The inlet water temperature affected to thickness of tubular ice as the ratio of inlet water temperature to thickness was 0.41 degrees Celsius per millimeter. Thus inlet water temperature affected to thickness of tubular ice according to theoretically results with 342% 43% and 8% error value between ice thickness and production time for 0-10 minutes 11-20 minutes and 21-36 minutes respectively

The internal control of organization in RajamangalaUniversity of Technology Isan, Surin campus

This research was to study about the internal controls of organization in RMUTI Surin campus. The purposes of this research were to study about the internal controls the performing process of organization and the comparison internal control of organization. The samplings for study were internal organizations in RMUTI Surin campus consisting of programs divisions and departments. The results were found that the internal organizations had performing about total internal controls were control status risk assessment control activity monitoring and evaluation and the information and communication at high level. The results of comparison were found that the internal organizations consisting of sub-divisions and sub-programs had internal control with overall and aspect. There was risk assessment higher than divisions. The divisions performed more than four years had information and communication and monitoring and evaluation higher than divisions performed only one-three years with overall and aspect. The internal organizations were sub-divisions and numbers of staffs were not different performances about internal control with overall and aspect.

Monitoring Controlled Car via a Computer with Wireless GPS Syste
Monitoring Controlled Car via a Computer with Wireless GPS Syste

Abstract The monitoring of controlled car via a computer with wireless GPS system project was invented to monitor a car via a computer with wireless GPS system that could send a cars coordination back to the controller when the car reached the specif ied position. All was done through a wireless communication. This project started by studying details and equipment of controlled car GPS system and programming of Micro Controller. These were applied in building a car which could be controlled via a computer with wireless GPS system. The Micro Controller program was also written. As a result of the project a controlled car could be monitored via a computer with wireless GPS system. The car could be moved by the computer to the specif ied coordination and coordination was sent back to the controller when the car reached its destination.
