This research is to study the efficiency of treating wastewater from dyeing fabric by the ozonation process. By using rutile TiO2 coated plastic media to catalyze. Which uses O3 generators with a capacity of 2.62 - 3.10 g/hr. By studying the factors that affect the treatment efficiency of COD and color such as the pH of the water used in the treatment at pH 3 pH 7 and pH 11 the initial COD concentration of 100% 50% and 25% which have values in the range of 100 -320 mg/L. O3 exposure time 120 min. From the study it is found that the efficiency of reducing the impurities in wastewater by the ozonation process in the pH 11 state the COD concentration at 50% can reduce the COD. And the maximum color is at 33.3% and 90% from the 550 ADMI color intensity with a COD of 180 mg/L. For the study of the efficiency of reducing the impurities of wastewater by ozonation process together with 2 g. of TiO2/1 L. of wastewater in the condition of pH 11 concentration COD Beginning at 100% with the ability to reduce COD values And the maximum color is at 40% and 80% of the 270 ADMI color intensity with a COD of 190 mg/L. The amount of O3 suitable for treatment has an average value of 0.0374 g/min./10.5 L. of wastewater. The duration of O3 exposure in both processes has a similar approach to the efficiency of COD and color treatment when increasing the duration of O3 exposure.

The objectives of the research on the application of dry ice in making chocolate mousse for the cold western dessert competition were to study the appropriate time for freezing chocolate mousse and test the physical quality of frozen chocolate mousse using randomized complete block design (RCBD) method at 95% reliability. The quality of senses sight color smell taste and texture and the overall preference were evaluated. The difference of mean was compared with by Duncan New Multiple Rang Test (DMRT) using a computer program to find the appropriate time to freeze chocolate mousse. 15 testers applied the 5 – point hedonic scale to test the product. Research results showed that the testers preferred the product that was frozen for 40 minutes the most. In terms of color smell taste and overall preference the mean was 4.50 4.41 4.00 4.35 4.25 and 4.21 respectively. The physical quality test results indicated that the texture of the mousse frozen for 30 minutes had the best hardness adhesion and flexibility 27.53 3.17 0.43 and 1.21 respectively. The product frozen at 40 minutes had the highest lightness (L*) yellowness (b*) and redness (a*) 40.15 13.03 and 22.31 respectively with the statistical significance (p≤0.05).

This Project ‘Thai Ikat Fabric Woman Working Suit from Sub-Ra-Wing Village’ aims for 1) to design the woman working suit that made from Sub-Ra-Wing Village’s fabric 2) to examine satisfaction of paticipants toward the designing processes of the woman suit according to 4 processes which are 1) the selection of Sub-Ra-Wing Village’s fabric that will mostly suit for the project 2) the process of design and selection woman working pattern 3) dressmaking and 4) examing the satisfaction of the viewers and paticipants toward the completed suit. Moreover the participant are 120 people aging 25-35 years old. The data was calculated by statistic percentage and mean as a result. The participants are; 87 people (72.50 percentages) are female. 85 people (70.80 percentages) are aging between 25 - 29 years old. 99 people (82.5 percentages) are undergraduated. 30 people (25.00 percentages) are students which equals to participants who have personal business. Lastly 55 people (45.80 percentages) are workers who have monthly income during 10001 - 20000 baht. The result of overall ‘Thai Ikat Fabric Woman Working Suit from Sub-Ra-Wing Village project ’ show that satisfaction at hight level (mean 4.46). Eaeh design it was found that. participants satisfaction to design 1 of coat and design 3 of shit and skirt at most level (mean 4.57 and 5.45 respectively). And design 2 of shirt and long pant design 4 of dress and design 5 of sweatpant. satisfaction at hight level (mean 4.47 4.41 and 4.32 respectively)

In this work solar erythemal ultraviolet radiation (EUV) which affects human skin and skin cancer was investigated at Songkhla province (7.2°N 100.6°E). EUV was converted to UV index then the data was used for model development and forecasting of hourly UV index using Artificial Neural Network (ANN). The ANN model has one input layer two hidden layers and one output layer. This input layer consists of extraterrestrial erythemal ultraviolet radiation solar zenith angle aerosol optical depth and cloud index which affect ultraviolet radiation and the output layer is hourly UV index. The results show that hourly UV index obtained from ANN and that from the measurement are in reasonable agreement with root mean square difference of 12.8% and mean bias difference of -2.4%. For forecasting of the hourly UV index the data for 7 days earlier was used for forecasting the next UV index for one day or nine-hour (08:00 am.-16:00 pm.). Multi-layer perceptron and back propagation algorithm were used in the model forecasting. The results show that the UV index from the model forecasting is reasonable agrees with UV index from measurement with root mean square difference of 17.0% and mean bias difference of 0.3%.

This paper presents a mathematical simulation to compared to operations a small distributed photovoltaic power plant in the distribution system. Practices transmission of electric power by small distributed solar energy With the PVSyst and IEC 61724 mathematical modeling programs the main objective was to study the % performance ratio photovoltaic power plants 5.95 MWp connected in the distribution system of the Provincial Electricity Authority voltage level 22 kV. Therefore this paper is presented as a mathematical simulation compared to operations a small distributed photovoltaic power plant in a distribution system. The results of the study show that the operation of small distributed solar power plants increases the efficiency to be able to produce the maximum electricity and continuously. The system was able to produce the highest power of 8954.9 MWh/year and had an average annual efficiency ratio of 77.84% receiving the highest solar radiation intensity and the highest annual total energy output of approximately 1837 kWh/m2
