The purposes of this project were 1) to study the formula of Thong Ek (Gold Foil-Decoration) from Lotus Seed Flour 2) to study the formula of Thong Ek (Gold Foil-Decoration)from Lotus Seed Flour and Lotus Stamen and 3) to study the nutrition facts the antioxidantand the detection of microorganisms test in Thong Ek (Gold Foil-Decoration) from Lotus SeedFlour and Thong Ek (Gold Foil-Decoration) from Lotus Seed Flour and Lotus Stamen. Thestudy found that the highest score of sensory evaluation results from the Thong Ek (Gold Foil-Decoration) from Lotus Seed Flour was the formulation number 2. The highest average ofappearance color smell taste texture and over all of the participants’ satisfaction were8.52 8.48 8.52 8.60 8.54 and 8.60 respectively. The result of Duncan’s New Multiple RangeTest DMRT showed differences with statistical significance at the 0.05 level (p≤0.05) in all 3formula. The highest score of sensory evaluation results from the Thong Ek (Gold Foil-Decoration) from Lotus Seed Flour and Lotus Stamen was the formulation number 2 as well.The highest average of appearance color smell taste texture and over all of theparticipants’ satisfaction were 8.46 8.52 8.48 8.56 8.62 and 8.68 respectively. The result ofDuncan’s New Multiple Range Test DMRT showed differences with statistical significance at the0.05 level (p≤0.05) in all 3 formulations. In addition the nutrition fact test result in Thong Ek(Gold Foil-Decoration) from Lotus Seed Flour and Thong Ek (Gold Foil-Decoration) from LotusSeed Flour and Lotus Stamen - 100 g. in dry weight found that the amount of energy and fatdecreased. In contrary the amount of protein fiber and carbon increased. When analyzed bythe FRAP (umoles TE) and DPPH (mg AA) the antioxidant and Polyphenol (mg eq GA) in theThong Ek (Gold Foil-Decoration) from Lotus Seed Flour and Lotus Stamen increased withstatistical significance at the 0.05 level (p≤0.05). Finally the detection of microorganisms inThong Ek (Gold Foil-Decoration) from Lotus Seed Flour and Thong Ek (Gold Foil-Decoration)from Lotus Seed Flour and Lotus Stamen test result found the E.Coli less than 3 and noneSamonella SPP.
การพัฒนาสื่อมัลติมีเดีย เรื่องการเย็บตะเข็บผ้าพื้นฐานวิชาการงานอาชีพ สำหรับนักเรียนชั้นมัธยมศึกษาปีที่ 1 โรงเรียนสาธิตมหาวิทยาลัยศรีนครินทรวิโรฒ ประสานมิตร (ฝ่ายมัธยม)
The purpose of this research was to: 1) use Multimedia Development to instruct Secondary 1 students learning Basic Sewing in Home Economics subject 2) compare academic achievement of students taught with the multimedia instruction and students taught with the conventional method and 3) study student satisfaction of the Multimedia Development technique Basic Sewing in Home Economics subject. A sample of 60 secondary 1 students attending Sinakharinwirot University Prasanmit Demonstration School was chosen using Cluster Random Sampling and were classified into 2 groups of 30 students; the first being the experimental group instructed with the Multimedia Development technique and the second being the control group instructed with conventional methods. The instruments of this research include lesson plans multimedia an evaluation form to track the multimedia efficiency a practice evaluation form and a questionnaire surveying student satisfaction. The statistics used for the data analysis were percentages mean standard deviation and a t-test. The results were as follows: 1) using Multimedia Development to instruct Secondary 1 students learning Basic Sewing in Home Economics subject achieved the efficiency of 82.14/80.06 2) the students taught with the multimedia technique have greater after learning achievement than those taught with the conventional method; statistical significance was at the .05 level and 3) the student satisfaction of the Multimedia Development technique Basic Sewing in Home Economics subject in high level is (x̅ = 4.42S.D. = 0.54)
การเปรียบเทียบกำลังทางไฟฟ้าของรถจักรดีเซลไฟฟ้า ระหว่างการตรวจวัดด้วยเครื่องติดตามระยะไกลและเครื่องมือวัดประจำสถานี
Rail transport is a type of transportation that strongly influences economic due to its ability to transport a large number of passengers and products per trip relying on diesel-electric engines. The objectives of this thesis were set to investigate and develop the electrical performance tracking system of long-distance diesel electric locomotives and compare the electrical performance measured by the diesel electric locomotive performance tracking system and measured from the measuring instrument at Diesel Engine Maintenance Station in Bang Sue. The electric diesel locomotive no. 4513 (Cummins KTA50-L) was selected as the study subject of the experimentation. The results showed that the power loss of the diesel electric locomotive from the conversion of alternating current to direct current was inversely proportional to the engine speed. The power losses between the low and high engine speeds were equal to 77.11 and 2.49 percent respectively. The above data reflects the limitation of diesel electric engine performance and should lead to the construction of a database for making decision on the right engine selection suitable for the towing load of the locomotive.

The research project on The potential of Siphonodon celastrineus Griff traditional medicinal plants of Thailand for treatment from local wisdom knowledge lead to the development of sustainable use with the objective of studying the botanical phytochemical and biological activity of the Siphonodon celastrineus to create confidence in the use of S. celastrineus in herbal medicine by using the bark leaves and fruit of the S. celastrineus to extract with 3 types of solvents. Each of hexane ethyl acetate and methanol respectively from low to high polarity. All nine extracts will be extracted. Preliminary examinations for phytochemistry Antioxidant activity by DPPH radical scavenging assay and quantitative determination of phenolic compounds by Folin-Ciocalteu method and antimicrobial activity were tested. The research found that. 1. The extract of the results of the methanol layer of the S.celastrineus shows a reduction in the amount of 11-diphenol-2-picrylhydrazyl (DPPH) had the highest EC50 equal to 31 mg/ml. The amount of phenol compounds found that the extracts from the methanol extract of S. celastrineus contain the amount of phenol. The highest concentration of 95.23 mg GAE / g dw 2. Extract from the bark of the S. celastrineus with methanol showed the best inhibition of the growth of Vibrio paraheamolyticus with the MIC value of 15.60 mg/ml. The extracts of the S. celastrineus leaf extracts with hexane showed the best inhibition of the growth of Vibrio cholerae with the MIC value equal to 31.25 mg/ml and leaf extracts with ethyl acetate showed the best inhibitory effect on the growth of Vibrio cholerae with a MIC value of 31.25 mg/ml and the extract of the fruit with ethyl acetate to inhibit the growth of Vibrio paraheamolyticus most with MIC equal to 15.60 mg/ml.

In this research the design of plasmonics interference using micro PANDA ring resonator as the source of single photon and entangled photon generation from the four-wave mixing process was studied. The coincidence of photons from Hong Ou Mandel effect between a wave guide and a micro PANDA ring resonator layer was detected. The whispering gallery mode of interference at the central top inducing the plasmonics signals at the outer nano gold coating PANDA layer was used to analyze from micro particles. Its quality factor was found at 106 of order magnitude and became appropriately to apply this plasmonics interference to be biosensor.
