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 study were to survey A Tendency towards Undergraduate Innovation and Education Technology Application of the Instructors at Rajamangala University of Technology Phra Nakhon .Goal to development to innovation and educational technology for the future. Measurement and evaluation were to questionnaires in five academic in component form and use innovation and educational technology administration learning resource instructional and teching and system to learn . . The target population of the study were to 484 acadamic staffs Rajamangala University of Technology in 9 faculty .The represectative sample of 214 acadamic staffs were collected by means of questionnaires and analyzed by mean standard individual and descriptive statistics presenting in form of tables. The finding of the were that 1. Componen form and use innovation and educational technology transparency and overhead projector visualiz and video projector will be used for presentation 2. Administration oflice automation will be use for administrative purpose teleconference will be used for coinmunication and pulic relatio and intenet will be important learning resources. 4 learning resource will be web resource for instructional supprt and many kinds of digital learnind materials will also used. Internet online will be use by learners which will enable them to study at any times anywhereand used teleconference 5.Instructional and teching and system to learn The teacher will be encouraged to think analyze and development learning activity to student think analyze discovery to reference electronics in library.For the teaching to think that a Tendency towards Undergraduate Innovation and Education Technology intemet will be used by learner which will enable thern to study at any time anywhere. More learning centers will also be established in various institutions.

Cooling water recovery from water distillation equipment was a research that has the objective to restore the cooling water from distillation equipment which installed at textile chemistry technology department laboratory at Textile industrial and fashion design in Rajamangala University of Phra Nakorn. The research plan was designing and developing the water distillation equipment type cyclon ultrapure water stills model WSC008 of Fistreem company. The outcomes found the designed system could save the tap water consumption 3462.72 square meters per year. That was implied 7617.64 Bath per year of tap water consumption could be save what the tap water consumption rate was 2.22 Bath per square meters. This system was paid back in 3.33 years and the benefit-cost ratio for single project (B/C ratio) was 1.26 (>1). Finally this project was successfully to save the tap water consumption and great benefit investment.

The purpose of this research is to study Development of Computer ted I nstruction Subject Change Management and to find out efficiencies Satisfac on towards the package. The research tools were : 1) Development of Computer Assisted Instruction Subject Change Management 2) Achievement tests 3) Quality a sessment and evaluation form for multimedia software and 4) Questionnalre of leamers satisfaction Sampling groups composed of 62 Bachelor degree (4 years) Faculty of Business Administration Rajamangala Unniversity of Technology Phra Nakhon Researchresulty revealed that the effciency of the Computer Instruction Package was at E1 / E2 = 81.65/82.39 corresponding with 80/80 creteria. Analysis to man of satisfaction of the sampling groups was rather at 4.18. It could be concluded that the Development of Computer Assisted Instruction Subject Change Management had the efficiency that could used for self study
