The purpose ofthis research was to study the effect oflistening to preferred music and natural on stress of the faculty of hberal. Arts Rajamangala University students. These subject were 90 Rajamangala University students aged 18 -21 They were devided into 2 groups with 45 each. The first group listened to prefenred music and the second group listened to natural music. Pretest -Posttest Desigh was used and the data was analyzed by using t -test The results ofthis study showed that: 1) There was statistical significant difference at .01 level between pre-test and post -test on Suanprung Stress Scale scores of the group listened to preferred music and the group listened to natural music. 2) There was no statistical difference on Suanprung Stress Scale scores between the group listened to preferred music and the group listened to natural music.

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.

This research studied combined toxicities of 4 generally found Polycyclic Aromatic Hydrocarbons (PAHs) - anthracene fluorene fluoranthene and phenanthrene – during growth of 3 legume seedlings - cow pea mungbean and longbean - planted in varied combination of PAH contaminant in soil. Results showed that mungbean growth was more sensitive to PAH co-contaminated soil than cow pea and longbean. Co-contamination of all 4 PAHs was more toxic to legume than each pair of PAHs. Shoot length and fresh weight of legume seedling were more sensitive to co-contamination of all 4 PAHs than root length. Dry weight of legume seedling was the least sensitive to co-contamination of all PAHs.

The purpose of this study was to Evaluation of Curriculum for the Bachelor of Science Program in Computer Technology of Rajamangala University of Technology Phra Nakhon. The CIPP Model was used as evaluated model. The samples in this research were 125 undergraduates 14 Instructors 17 graduates and 11 employers of graduates. The 4 questionnaires of rating scales was used as the research instrument. Percentage mean standard deviation were statistical method to analyze data. The results were as follows: 1. The samples agreed with the Context Evaluation in the aspect of curriculum objectives curriculum structure curriculum content were in moderate levels. 2. The samples agreed with the Input Evaluation in the aspect of Characteristics of undergraduates and Characteristics of instructors were in high levels supporting education was in moderate levels. 3.The samples agreed with the Process Evaluation in the aspect of curriculum Management. teaching Management experience training were in high levels . 4 . The sample’s satisfaction towards Input Evaluation in the aspect of professional knowledge and Professional Characteristics were in moderate levels Ethics was in high levels .

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.
