We present the comparison of CDMA MAC protocol with and without beat noise by using 2-D optical CDMA MAC protocol over WDM networks. We use the asymmetric primehop sequence code. Moreover we analyse the effect of the number of available wavelengths in tenns ofaverage number of attempted to transmissions per time slot (offered load) and beat noise is considered. The presented numerical results based on the throughput and delay time versus the offered load. We divide into two parts. The first one we consider the effect of the number of available wavelengths. Another is the effect of with and without beat noise in the 2-D OCDMA over WDM systems.

This action research has a purpose to study the personality of students at the Industrial Engineering Department Faculty of Technical Education Rajamangkala University of Technology Phranakhon. By using the Peter Lauster personality test this research compares the students personality before and after taking suggestion test on personal development. The subject of test consists of 13 students selected purposive selection from students at the first group of B.S. Technical Education (5-year curriculum) on Industrial Engineering Major. The collecting-data instruments are the Peter Lauters objective test namely the self report inventory and the authors questionnaires with check-list method. The data are analyzed by using the percentage and arithmetic mean. The research results are listed as the following: 1. The studentspersonalities before taking suggestion test on personal development in middle and low level are approximaicly 62.44 (largest group) and 6.88 percent respectively totaling approximately 69.32 percent. 2. The result from the personality test : the rather low and low level of self confident measurement are totally 76.91 percent. 3. After taking the suggestion test on personal development the good level is approximately 57.85 percent increasing about 27.18 percent relative to the same level before taking the suggestion test. On the other hand the low level is approximately 0.43 percent decreaing about 94.47 pecent relative to the same level before taking the suggestion test. 4. The findings from the interview and observation show that after taking suggestion test on personal development the most students not only improve their overall personalities but also build their self-confident as well as increase their well-adkist personalties resulting in the enhancement of their self-esteem.

The purpose of the research was first to study the need of information technology application in second to study the types of information technology services that is effectively corresponding to the need of users. The third is to study information technology application in cassroom teaching and the last forth is to apply all these strategies to Rajamangala University orf technology phra Nakhon. In the research the examined population was both academic staffs and students of Rajamangala Univessity of Technology Phra Nakhon. Their samping mumbers selected from all 9 faculties were total 1506 peoplecounted of 80.97 percentages. The research tool used was questionnaires in order to engaging the effectiveness and the need of basic factor of information technology. For the data analysis one=way analsis of variance (ANOVA) approach was chosen for the study. In this study the results showed that most staffs thought it had majior effectiveness of information technology mangement with a mean value off 3.475 whereas most students though it was medium effectiveness with a mean value 3.393. For the needs of information technology most staffs considered it a hight range of an average at 4.420 while the students believed its importance with an average of 3.686. Besides for this same need both staffs and students from various facultes had same major opinons that there was no difference at the statistic significant level of 0.05
