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.

The purposes of this research were to study and compare the satisfaction at rajamangala versity of technology Phra Nakhon Classifled by sex age education level type of personnel and experiences. The research samples were 1172 personnel from Rajimangala University of Technology Phra Nakhon. data was complied through the use of a questionnair with a statistical reliability of 0.9741 questionnaires retumed. There were 565 complete questionnares used in the data analsis process. the statistics used in the data analysis were percentage mean standard deviation t-test and f-test The results of the study found that personnel were with their role and position within the internation Afdairs Division at a mendium level (X=3.13 S.D. = 0.72) and documented the personality of offcers at high level (X= 3.62 S.D. =0.67) The results of the hypothesis testing yieded the following infomation : 1) A personnels sex did not have a signifcant statistical impact on the study with the only exception being the role and position (regitering a statistical difference of 0.05). 2) A personnels age did not have a singnificant statistical impact on the study. 3) A personnels educstion level did not have a sihnificationt statistical impact on the study whith the only exception being the role and position (registering a ststistical difference of 0.05). 4) A types of personnel did not have a siatical impact on the study. when fonusing on persons role and position there was a significant statical difference of 0.05.

The purpose of this study was to compare undergraduate students reading writing performance and interest in learning English through reading instruction with and without computer in PowerPoint Program at Rajamangala University of Technology Phra Nakhon Bangkok Commercial Campus. The subjects for this study consisted of 80 undergraduate students in the first semester of the 2005 academic year of Rajamangala University of Technology Phra Nakhon Bangkok Commercial Campus. They were selected by using simple random sampling and divided into the experimental and control groups with 40 students in each. The randomized control group pretest -posttest design was used in the experiment. The experimental group was taught through the method in the reading instruction with computer in PowerPoint Program whereas the control group was taught through the method in the reading instruction without computer in PowerPoint Program. Each group was taught with lessons of the same content for sixteen 150 minute periods. The instruments used in the study were English reading writing performance tests and interest in learning English. The t-test for independent samples score was statistically used for data analysis. The results of the study indicated that: 1. The English reading performance between the experimental and control groups was significantly different at the .05 level. 2. The English writing performance between the experimental and control groups was not statistically significant. 3. The interest in learning English between the experimental and control groups was significantly different at the .05 level.

This study was aimed to study the general situation of business to compare the financial ratios between life insurance business and non-life insurance business and to study the factors which affected the performance of insurance business. The study results showed that the financial ratios between life insurance business and non-life insurance business were compared it was found that financial ratio of life insurance business was better than non-life insurance business for 6 ratios as follow: Net Premium Return on Assets Total Assets Turnover Policy Liability to Capital Fund Current on Premium and Debt-to-Equity Ratio. As for the study on the factors which affected the performance of insurance business it was found that the performance of life insurance business were affected by the following financial ratios: Return on Investment (0.810) and Dividend Payout (0.354). The factors which affected the performance of non-life insurance business were Policy Liability to Capital Fund (2.678) Debt-to-Equity Ratio (1.370) and Provision-to-Assets Ratio (0.755). And it could be concluded that the difference between the type and the size of business affected the performance differently.
