The purpose of this study was to evaluate the subject of Statistical Analysis in Business(02-311-133) in the curriculum of the Faculty of Science and Technology Rajamangala University of Technology Phra Nakhon. The following aspects were studied : the appropriate objective outline content of the curriculum methods of teaching and learning instructors students teaching aids materials classrooms evaluations of the curriculum and achievements of the students who had studied this subject. The sampling group of this study was comprised of 6 instructors who taught a course in Statistical Analysis in Business 324 students who had studied the course and 76 students who had graduated. The research tools were a questionnaire and an interview. The statistics used in data analysis were percentage arithmetic mean (X) and standard deviation (SD.). The Results ofthe study were that 33.33 % of the instructors had experiences in teaching more than 10 years but had conducted fewer researches; the objective outline and content of the curriculum were appropriate and applicable; the teaching aids did not work properly because of no good maintenance; in teaching and learning no activities and fewer group works were assigned to students to practice; the evaluations of the curriculum should not have various forms; there were less of students achievements in synthesizing problems and applying their knowledge to solve problems.

This research aimed to develop the prototype of information management systems for achievement evaluation and grade submission of Ubon Ratchathani Rajabhat University. The research process begins to study the need for the development of the prototype of information management system for achievement evaluation and grade submission. The research instruments were interview and questionnaires. This research found that lecturers needed to have a developed model for this system. It was found that the system including achievement evaluation grade submission and storing data were validity tested by grade information. Moreover the prototype model developed could be used as a model for the present education evaluation and grade submission at the university.

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.
