This article presents texture analysis of crispy snack products by using Acoustic Emission (AE) to measure sound that occurred when the products were chewed or broken. This technique has currently gained great interest from food scientists. A sound emitted from food was found to be related with microstructure and crispness. Measurement of sound emitted from food when it was chewed consists of three main steps: 1) Apply force on piece of food with a texture analyzer; 2) Detect sound signal with an acoustic envelop detector; and 3) Interpret the collected data of mechanical force and acoustic emission.

The objectives of this research were: 1) to study teachers opinions towards environmental management in private kindergarten schools and 2) to compare teachers opinions towards environmental management classif ied by gender age education and teaching experiences.

The study is on “Satisfaction to Marketing Communication Tools : A Case Study of Business Organization of the Office of the Welfare Promotion Commission for Teachers and Educational Personal (BOWT)”. The aims of the study were (1) to study the level of exposition on education information as well as the level of satisfaction of marketing communication tools of BOWT (2) to compare the satisfaction towards marketing communication tools of BOWT among groups with different demographic characteristics and (3) to study the relationship between the exposition of education information and the satisfaction towards marketing communication tools of BOWT. The method of data collection had been carried out through questionnaire survey. The sampling groups consist of 400 teachers professors and instructors. The findings showed that the sampling groups received information on education at the moderate level. The highest exposition level is on general education information followed by information on production and distribution of BOWT goods and general information respectively. The satisfaction towards marketing communication tools in general was rated as “high”. For different marketing communication tools the highest level of satisfaction was rated on sale representatives who gave any information at the ( ง ) point of purchase of BOWT. The high level was rated on leaflets and catalogues. The low level was rated on newsletter or “Suksapan News” which was sent through postal mails. Moreover it was found that certain factors include age level of education employment duration office agencies/units and monthly income affected the satisfaction towards marketing communication tools with statistical significance at 0.05 level. The overall information exposition was in line with the satisfaction towards marketing communication tools at the “high” level. Also it was found that marketing communication tools through website (www.suksapan.or.th) poster / banner leaflet / catalogue newsletter of “Suksapan News” BOWT training programs and public relation news affected the exposition of education information in 3 areas i.e. general education information production and distribution of BOWT products and other general information.

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.

The objectives of the study were to find the arrival rate of applicants who applied to study at Rajamangala of Technology Pra Nakhon North Bangkok Campus the service rate of admission officers and to analyze queuing system in order to improve the admission system. The sample was 1722 technical students who applied to study in 10 divisions in 2007 and 2008. The plication date was collected every 10 minutes in each one-hour period from 09.00 am. to 16.00 pm. For 6 days. The study found that the distribution of the number of applicants was Poisson distribution. The highest arrival rate 1.29 student/min was at the second period and the lowest arrival rate 0.06 students/min was at the sixth period. The Distribution of service time at each station was exponential distribution. The highest service rate 0.67 min/student or 1.49 students/min was at the second station entering data into a computer. Queuing analysis in this study was series network. The analysis found that the highest expected number of applicants in the system 150 student/hour was at the first station in the second period and in the sixth period there was almost none. The highest expected number of applicants in the queuing system107.40 student/hour was at the first station in the second period The highest expected waiting time in the system.1.92 min/student and in the queuing system 1.37 min/student were at the first station. The probabilities of none of applicants in the system at the first the second and the third station in the sixth period were high 0.97 0.95 and 0.98 respectively. The proper value of the expected number of applicants in the system set in this study was not more than 60 student/hour and not less than 30 student/hour. The proper value of the waiting time in the system was not more than 1 min/student and not less than 0.5 min/student for stations for stations with more than one servers. The analysis found that at the first station one more server should be added in the second the third and the forth period and one less server should be reduced in the sixth period.
