The purposes of this research are to study and improve the productivity process of washing tables by setting standard time a case study of stainless manufactories. Nowadays the manufacturers don’t know the production capacity. That leads to the problems of manufacturers’ work control and late product delivery to the customers. The study is proposed to improve work procedures by designing operation process chart (OPC) the setting of operation stations Operation process chart time (OPC TIME) and finding the standard time in product manufacture. As for the operation process and the standard time setting the research revealed that the standard time of welding station in assembly process for the frame table sink tap nozzle high neck sink flick and welding station of all assembly parts were the first the second the third and the fourth respectively. The researchers’ suggestions were to add 2 welding machines and 2 workers in assembly process so as to work more efficiently so that it can decrease the total processing time from 855.24 minutes/set to 645.91 minutes/set or 24.47 % reduction.

This study examined the efficacy of two sanitizers; peroxyacetic acid (PAA) and sodium hypochlorite (NaOCl) in reducing total microbial counts on the carved leaf-shape surface of five types of fruits and vegetables: pumpkin carrot radish cantaloupe and Japanese cucumber. The samples were dipped for 3 or 5 min in various concentrations of PAA (40 60 or 80 mg/L) and NaOCl (50 or 75 mg/L) with distilled water as the control. After dipping the samples were drained for 5 min and the total plate counts were determined in triplicate. Dipping in 60 mg/L of PAA for 3 min was the best treatment for reducing microorganisms on the surface of carved carrot and radish; and 80 mg/L of PAA for 5 min was the best treatment for reducing microorganisms on the surface of carved pumpkin cantaloupe and Japanese cucumber. PAA at concentration 60 -80 mg/L showed potential as an effective sanitizer for carved fruits and vegetables more so than both concentrations of NaOCl.

This paper presents the design of automatic watering system using sun tracking as an energy source .The objective is to design the automatic watering system for fruits grown in both areas without electricity. The solar panel can be moved along the direction of the sun cover an altitude - azimuth dual axis as an energy source of the system. The 20 longan trees are used in the experiment. The DC motors and the solar panel is controlled and rotated by the microcontroller to the position of the maximum light intensity. The watering system section will use a technique to measure the soil moisture sensors ECHO2-20 with real time PC based monitor system by Visual Basic Studio. As for the experiment results it was found that the energy stored by the developed solar tracker increased to 17.72 percent in comparison to a solar panel fixed installation. The watering appropriate soil moisture content is 12 percent and stops at 25 percent resulting for the garden moderators to save time and labor.

The objective of this research is to find out the factors that affect academic achievements in the subjects which are fulfilled by using e-Learning in RMUTP by using questionnaire. The questionnaire is separated into 2 parts the first part is to find out the satisfaction level of each factor and the second part is to find out the effective level of each factor. After the researcher analyzed the data of tested questionnaire of 169 samples students by using Simple Sampling method from 294 students who study in the subjects which are fulfilled by using e-Learning the information were as follows: 1. The satisfaction level of factors is between normal And high the mean of satisfaction level of computer and internet infrastructure factor is normal ( x = 2.81) the mean of satisfaction level of supporting e-Learning system factor is normal ( x = 3.27) the mean of satisfaction level of the supporting personal factor is high ( x = 3.50) the mean of satisfaction level of e-Learning benefit is high ( x = 4.11). 2. The mean of effective level of computer and internet infrastructure factor is very high ( x =4.29) and the mean of effective level of supporting e-Learning system factor is normal ( x =2.98) In concluding to above information the computer and internet infrastructure factor is the factors that affect academic achievements in the subjects which are fulfilled by using e-Learning in RMUTP.

The purposes of this study were 1) to study exercise behavior and media exposures 2) to compare personal factors with exercise behavior and 3) to study the media influences and factors affecting exercise behavior of the elders in Bangkok Metropolis. The data were collected through 450 elders residing in Bangkok Metropolitans. Data analysis employed frequency percentage mean (x)and standard deviation (SD.). Statistics used for hypothesis testing included t-Test Oneway ANOVA and Stepwise multiple regression analysis. The study presented
