การประดิษฐ์เซรามิกบิสมัทโซเดียมซาแมเรียมไททาเนต-แบเรียมไททาเนตด้วยเทคนิคการสังเคราะห์แบบเผาไหม้
Ceramic Bismuth Sodium Samarium Titanate - Barium Titanate at the concentration of samarium 0.04 mol% was preparing by ball mill technique. This research has increased the temperature in the combustion process at different temperatures from 940960 and 970 degrees Celsius for 7 hours. The results showed that firing at different temperatures made the ceramic beads very dense. In addition the study of the crystal structure by XRD technique to study the structure of the ceramic BSNT-BT found that the structure is the same substances in the ceramic group BaTiO3. The results of the study of dielectric properties and ferroelectric properties It was found that the dielectric and P-E hysteresis loops were related and tend to correlate with increasing density with sintering temperature. The mechanical properties of ceramics were tested by measuring the hardness of ceramics at different temperatures with temperatures affecting the changes in various properties of ceramics BSNT-BT.

This research is a study on treatment of Water Dyes from textile dyeing industry by Advance oxidation process with Ozone and hydrogen peroxide (H2O2). In this study Ozone generators with a capacity of 1.0 - 3.0 mg/ hr. were used to study the appropriate factors for treatment with adjusting wastewater conditions (pH 3 pH 7 and pH 11) Ozone exposure distance 120 minute the initial COD concentration is 250 - 1000 mg/l. and adding hydrogen peroxide at 4 8 and 12 ml/l. For the study found that above mentioned factors have an effect on the efficacy of color and COD treatment which the experiment at pH 11 used to Ozone treatment and added 4 ml/l. of H2O2. It makes the highest COD treatment efficiency when compared to pH 3 pH 7 and added more H2O2. it doesn’t affect to the higher of treatment efficiency. In addition it was found that higher initial COD concentration decreased treatment efficiency which the experimental ability for COD treatment has highest value was 46 percent and the COD concentration was 250 ml/l In order that when COD concentration in synthetic color water was increased to 500 ml/l and 1000 ml/l. it was found that the COD efficiency decreased to 31% and 40% respectively. For the treatment of Water Dyes from textile dyeing industry by oxidation process with Ozone together with hydrogen peroxide (H2O2) at pH 7 will has the highest of treatment efficiency. However the consideration of suitability for pH configuration used to treat both color and COD should choose pH 11 because it can treat both color and COD that makes the waste water quality meet the standards required by law. In addition if we consider the effectiveness of turbidity and BOD found that the decrease of dirtiness tends to be in the same direction with COD both 2 parameters.

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)

The objective of this research was to study the antibacterial activity of 16 samples of indigo dyed fabrics that are produced and sold in Sakon Nakhon Province. Effect of moisture and pH of indigo dyed fabrics on bacterial growth were also determined. The result of the study shows inhibition of S. aureus TISTR 746 and E. coli TISTR 073 by agar diffusion plate test all samples could inhibit Saureus TISTR 746 (accounted as 100%) and only 9 samples could inhibit E. coli TISTR 073 (accounted as 56.25%). Whereas the study of antibacterial activity by AATCC test method 100-2004 at 24 hours was found that the natural indigo dyed fabrics code A3-1 could inhibit both bacterial strains in the highest level. The result also shows the effect of moisture and pH of indigo dyed fabrics on bacterial growth it was found that the increased humidity levels of indigo dyed fabrics have effect on the reduction of the inhibition efficacy of both strains. While indigo dyed fabric with pH 3.0 was found to inhibit most of the growth of both strains. In addition images obtained using a scanning electron microscope (SEM) could clearly confirm the property of indigo dyed fabric on inhibition of S. Aureus TISTR 746 and E. coli TISTR 073.

Research on the community of Participatory Learning Practice Fabric Pattern to Development of Local Hand-mend Cloth Products of Sewing Community Enterprise and Craft Khao of Sewing Khao Kaew Srisomboon Thung Saliam Sukhothai Province. The objectivity of this project is to study the patterns of cloth to develop hand-woven fabric products. The learning practice of local fabric patterns to develop 5 sets of hand-woven jewelry products then 5 sets of jewelry experts were asked to consider selecting suitable hand-woven jewelry sets for making. 3 sets of jewelry and asked 5 experts from the community state enterprise sewing and artificial arts to transfer the invention of handwoven jewelry to the community 1 set and to study the satisfaction of the target group of 30 people and analyze the data. By using statistics frequency percentage standard deviation and mean with the following analysis results. The findings of the study were as follows. It was found that Local fabric patterns Appeared in 3 traditional fabric patterns: Saeng pattern Plain pattern and Kaew pattern. Learning practice of local fabric patterns for the development of hand-woven fabric accessories. All 5 jewelry experts chose the style of jewelry set A set B and set D commenting that the style has suitable elements of jewelry. In particular the combination of local fabric patterns and geometric shapes creates a contemporary look. Size and proportion should be adapted to the proportion of the wearer. And the use of color always use the original color of the fabric especially red. Because it is a color that is unique when it comes to making the piece it will help make the jewelry more beautiful and dimension as well as indicate the identity of the people of Khao Kaew Srisomboon. The expert representative of the community enterprise group I chose the A Series because of the contemporary style. Can generate income for people in the community And the satisfaction of the target groups towards making jewelry sets it was found that the product Satisfaction with aesthetics was the highest at an average of 4.83 in terms of suitability of the fabricated material. The satisfaction of the materials used was interesting at an average of 4.67 in terms of utility. Satisfaction in wearing on various occasions at the average 4.66 and distribution. Satisfaction in the jewelry trade show at an average of 4.60 communities working on learning patterns of local fabrics to develop hand-woven products. Has given importance to the history the meaning use of color and the belief in cloth pattern hooves from shared memories of people in the community. Fabric patterns both Saeng pattern Plain pattern and Kaew pattern Therefore it is a reflection of the people in Khao Kaew Srisomboon community that has inherited the wisdom heritage that is more than precious. Rather it is the inheritance of intent from generation to generation.
