The Study and development of certain microorganisms with high capability in nanosilver particle biosynthesis
This research report is manipulated that summarized the moment of research project in the subject of “The Study and Development of Certain Microorganisms with High Capability in Nanosilver Particle Biosynthesis”. This project had been take time in 12 mounts. We focused on the isolation of microorganism that from manufacturing process and forming in gems and jewelry industry. Results showed that the initial silver refinery microorganism performed only in terms of Pseudomonas genus especially in AgNO3 solution. In contrast Bacillus genus was not clearly effective silver refinery. These results could be the basis information for establish and develop system for silver refinery and/or silver quality improvement with biological process especially microorganisms in future.

The purpose of this research were to create and determine the efficiency of computer assisted instruction lesson on electronic circuit multimedia for secondary school students (grade 9) Triamudomsuksanomklaononthaburi school. The research sample consisted of 120 students of secondary school students (grade 9) during semester 2 in the academic year of 2012. The data were analyzed using mean standard deviation level of difficulty and discrimination power. The results found as follows : The efficiency of computer assisted instruction lesson electronic circuit multimedia for secondary school students (grade 9) is 80.15/83.35 and the students’ satisfaction with the computer assisted instruction lesson electronic circuit multimedia was at highest level ( = 4.60 S.D = 0.74)

This research aims to develop and calculate the efficiency of electronic books injection mold design engineering for Plastic Mold Technology1 (04-812-313) The participants of this research were 40 third year students who enrolled in Plastic Mold Technology1 subjects in first semester 2013. The research tools were 1) an electronic books 2) a questionnaire for measure an efficiency of electronic books 3) an achievement test. Data were analyzed by using difficulty discrimination validity index of consistency The result showed that quality of electronic books injection mold design engineering was in a very good level with higher sufficiency mean = 1.13 than criteria at mean = 1 and was very useful for Plastic Mold Technology1 (04-812-313)

This research aims to solve the basic knowledge problems of undergraduate students who study Calculus 1 for Engineers in the Faculty of Engineering Rajamangala University of Technology Phra Nakhon. Basic Mathematics tutorials are conducted in order to improve their knowledge which leads to increase the efficiency of learning the Calculus 1 for Engineers. The basic mathematics lessons are designed and their efficiency is assessed in the tutored group using the 60/60 criteria. The pretest and posttest are assigned to both tutored and tutorless groups as well as the tutored student satisfactions with thedesigned lessons and the Calculus 1 for Engineers are conducted. The result shows that the efficiency of the designed lessons is 76.60/64.67 which is higher than the criteria; hence they are proper to be used. For the treatment group the posttest grades are higher than the pretest grades significantly (.05) with the effectiveness of 34.67. The comparison of the learning achievement for the Calculus 1 for Engineers shows that the grades of the tutored group are higher than the grades in the tutorless group significantly (.05) as well. The student satisfactions for both the designed lessons and the Calculus 1 for Engineers are at the levels of good and very good.

The research paper is considered as quantitative work which has the following objectives: 1) to study Rajamangala University of Technology Phra Nakhon staffs A Study of behavioral factors associated with the use of online registration via the website.2) to study the relationship between their attitude and behavior towards using the registration system via the website. And 3) The compare problems in the system register online the website. Rajamangala University of Technology Phra Nakhon. The subjects of the study are 51 in-service teaching staff and 349 undergraduate students from 9 faculties. The instruments in this research consisted of questionnaire which the data were analyzed by using percentage mean standard deviation X2 t-test oneway analysis of variance and Scheffe’s method were utilized for data analysis. The results of the study revealed that: 1. The behavioral factors associated were age status and experience of used internet that related with behavior towards using the registration system via the website. In the objective of using the registration system via the website the time and location was statistically significant at 0.05 levels. 2. A good attitude in using the registration system via the online website had related with behavior of using the registration system via the website. The objective and the time of using the registration system via the website were different. 3. The behavioral factors associated were gender status and learning center which had related with different problem in using the registration system via the website.
