The results of the study offormulas and processes and conducted tests on chemical composition physicalquality microbial quantity and sensory evaluation found that suitable for preparingmilk from Water caltrop to be used in the production of milk imitation products fromWater caltrop Is the amount of water chestnut: water in the ratio 1: 2.5 (weight: weight).The amount of xanthan gum which is used as an appropriate stabilizer is 0.1 % of thetotal ingredient and effect to the product has the same texture and not separate thelayer. After storage at 5±1°C for 9 days this product was shown to be safe forconsumption. The developed product was 29.22 kcal/100g and protein fat andcarbohydrate content were 3.37 0.22 and 3.42 respectively. The consumer giving themost importance to the health benefits and the Novelty or products. All of consumerwere accepted on the product for beneficial of health. The consumers test resultindicated the most consumer accepted the product at the moderate level and 82% of them were interested in buying at 20 baht per 189 ml glass bottle of the product.

Weather forecasts are very necessary to predict the future weather conditions. The important thing in forecasting is the model and variables. The model used in the forecasting must be accurate and effective. In addition the variables used in forecasting must be comprehensive and appropriate to be able to represent the forecast. The initial conditions for forecasting must be appropriate and reliable. There are many methods to generate the initial conditions in forecasting. To generate the initial conditions for winter monsoon prediction with Kalman Filtering method which is a method used to predict the status of various systems and able to create values of variables used in forecasting to have a variety of similarities can be used as a starting variable in forecasting very well. In this research the winter monsoon prediction by the Shallow Water Model and validating the initial conditions by Root Mean Square Error (RMSE). The result of weather prediction in the winter monsoon can be used the Kalman Filtering method for generate the initial conditions.

The objectives of this research were to study the growth rate of microbial sludge in the fermented juice and to study the efficiencies of fermented juice and melodies on Fairy Rose growth. In the experiments the growth rate of microbial sludge was analyzed with 10 parameters for 4 weeks. Moreover the Fairy Rose was divided into 2 groups used and non-used the fermented juice. Each experimental group was tested with 3 types of melodies including jazz classical and Mozart. All experiments were set 3 replications by the total number of 24 Fairy Roses. The growth of the Fairy rose was analyzed by considering the number of leaf Height length of root and mass. The experimental results showed that the growth of microbial sludge in fermented juice was good and produced microbial sludge in fermented juice approximately 1063 ±158 mg/L on average. The Fairy Rose more growing with water and fermented juice. The number of leaves was 144±11 leaves in average Height was 30±1 cm in average Length of root was 38±8 cm in average and weight of Fairy Rose at the end of experimentation was found 400 g in average. In the case of melody affected Fairy Roses growth was classical. The growth of fairy roses found that the number of leaves was 143±6 leaves in average height was 29±1 cm in average Length of root was 34±1 cm in average and weight of Fairy Roses at the end of experimentation was 93 g in average

Non-destructive test with Acoustic Emission technique was used for monitoring of the corrosion in the above ground oil storage tank. In the analytical characteristics of acoustic emission wave however Acoustic Emission test has to be prior used for the location detection of corrosion especially indication of the severity of corrosion. In this research the relationship between the corrosion rate and the sound wave energy was studied. The corrosion and damage detected on the surface of the aboveground storage tank was determined by the Acoustic Emission Test. Nine pieces of low carbon steel grade SS400 was soaked in sodium chloride solution in simulated tanks at concentrations of 1.5 3.5 and 5.5 wt%. Next the corrosion activity was checked by performing with the Acoustic Emission Testing for 1 hour and thus calculating the corrosion rate of the test specimens. From the experiment it was found that the rate of corrosion affects the Acoustic Emission Energy. The corrosion rate was increased with the concentrations of the solution increasing from the corrosion process. The corrosion rate was also increased with the sound wave power increases. Therefore in order to achieve the corrosion rate and the position of the defects on the inner surface of the tank non-destructive testing with acoustic emission technique can be factually chosen for this specific application.

The purpose of this study was to study 1) opinions and needs of cooperative saving members towards the existing welfare services and their additional needs 2) to compare the opinions of members of the savings cooperative on the welfare services received and 3) to compare the demand for additional welfare services of the saving cooperative members. The personal factors were classified and a questionnaire was used as a tool to collect data. The data analysis statistics included percentage mean and standard deviation. The hypothesis was tested using t-test and one-way ANOVA was applied. The Scheffe pair test was used if the statistical significance was found at 0.05. The research disclosed that the majority of respondents were married males between the ages of 51-60 years old whose educational level was lower than the bachelor’s degree. They mostly worked as government employees with more than 10 years of service and earned monthly income of 20001-25000 Baht. Their existing welfare services are capital stocks followed by ordinary and emergency loans respectively. Different opinions in the comparative analysis were found among the individual factors of welfare services in terms of their gender age status and education. However they were similar in terms of the type of employment service term and monthly regarding to the welfare services received. As for the comparative analysis of individual factors it was revealed that there were different needs for welfare services because the members with different education levels required distinctive welfare services at the statistical significance of 0.05. However ง the personal factors including gender age status type of employment service term and monthly income were similar concerning their needs for additional welfare services.
