The Study and development of certain microorganisms with high capability in nanosilver particle biosynthesis
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 study and development of the wickerwork handicraft making for building the product development guideline for the sustainability of changwatang thong

This research. Study and Development of the Wickerwork Handicraft Making for Building the Product Development Guideline for the Sustainability of Changwat Ang Thong . The test concept is to develop handicraft can stand on the market of high competition in the state. It is a long time handicraft production process is a process that has been inherited wisdom within the family. But when the society changes. Consumers are increasingly demanding. Crafting an increasingly competitive. The creation of only one production order. The development of the craft did not creative enough. Community as a production base for the capitalist market to find the space to the community. Just profits.

The study of learning activites' results using (p) spc2pas model of business finance for business administration undergraduates at Rajamangala University of Technology Phra Nakhon
The study of learning activites' results using (p) spc2pas model of business finance for business administration undergraduates at Rajamangala University of Technology Phra Nakhon

The objective of this study was: to experiment the activity using the (P) SPC2PAS model for Business Administration Undergraduates in Rajamangala university of Technology Phra Nakhon in (1) a comparison of achievement test of post-scores with pre-test scores of the first phase; (2) a comparison of post-test scores with pre-test scores of the second phase; (3) the result of the activity’s self-reflection of knowledge attitude and performance of learners; and (4) learners’ attitude towards an (P) SPC 2 PAS model. The research procedure was comprised of two phases. In Phase 1 there was the adjusted (P) SPC2PAS Model which was applied to use with Business Administration Undergraduates in Business Finance at Rajamangala University of Technology Phra Nakhon. In Phase 2 there was the experimentation of (P) SPC2PAS Model with Business Administration Undergraduates in Business Finance at Rajamangala University of Technology Phra Nakhon. The experimental group was the forty first-year financial undergraduates in the 2nd Semester of Academic Year 2010. The research instruments were: the business finance achievement test the self-reflective learning checklist and the attitude questionnaire analyzed by percentage mean standard deviation and the t-test. The result of the study showed that: (1) the mean scores of the sample group in the first phase of business finance comprehension’s post-test was significantly higher than of the pre-test at the statistical level of 0.05; (2) the mean scores of the sample group in the second phase of business finance comprehension’s post-test was significantly higher than of the pre-test at the statistical level of 0.05; (3) The learners’ spiral-learning development of the all activities’ self-reflection of knowledge attitude and performance of learners was 100 percentage; and (4) learners’ attitude towards using (P) SPC2PAS Model of Business Finance for Business Administration Undergraduates at Rajamangala University of Technology Phra Nakhon in the areas of the activity model teacher’s role instrument and learning evaluation was in mean scores at good to very good level-positive attitude.

การศึกษาจริยธรรมของนักศึกษาชั้นปีที่ 1 มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร ที่มีภูมิลำเนากรุงเทพมหานครและต่างจังหวัด

The purposes of this research were to study and to compare the ethics of the first-year students at Rajamangala University of Technology Phra Nakhon who were from Bangkok with the ethics of the ones from other provinces. The samples chosen by purposive sampling were the first-year English for International Communication students of the Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. They were divided into 2 groups and each group consisted of 30 students. The first group was from Bangkok while the second group was from other provinces. The instrument was a questionnaire. The results revealed that there was no significant difference (at the level of .05) of the ethics of the first-year students who were from Bangkok and of those from other provinces. The mean scores and standard deviations of the results of the first group were 3.82 and 0.34 and of the second group were 3.89 and 0.34 respectively.

The study of quantum noise of four-wave mixing process of entangled photon generation within a nonlinear fiber optic ring resonator
The study of quantum noise of four-wave mixing process of entangled photon generation within a nonlinear fiber optic ring resonator

The three types of Hamiltonian describing photon-photon and photon-phonon interactions within an optical ring resonator in which quantum noise in fiber optics is generated are given. The Markov-Born approximation and +P representation of photon states in phase space are used in order to eliminate the reservoir state variables by substituting all into the master equation to get the coresponding Fokker-Planck equation. The corresponding Langevin equation describing evolution of quantum states of an entangled photon is analyzed. The optimum results show that the occuring quantum noise can be reduced from the three main parameters where the surviving polarized entangled photon can propagate in the fiber optic system for a long time until photon processings are attained.
