The purpose of this study was to study and compare executives satisfaction on the characteristics of graduates in faculty of engineering at Rajamangala University of Technology Phra Nakhon in 3 aspects: Academic Ethics and Professional Characteristics. The executives were classified by gender age type of enterprises type of business size of enterprises and major subjects of graduates. The samples in this research were 56 executives. The study participates selected by Stratified random sampling. The 40 item questionnaires of Likerts rating scales was used as the research instrument. Percentage mean standard deviation t -test for dependent sample t -test for independent sample F -test and LSD analysis were statistical method to analyze data. The results were as follows: 1.Executives satisfaction on the characteristics of graduates in each aspect and all aspects were at the high level. 2.Executives expectancy on the characteristics of graduates in each aspect and all aspects were at the high level. 3.There was no significant difference for executives satisfaction on the characteristics of graduates in each aspect and all aspects between male and female executives. 4.There was no significant difference for executives satisfaction on the characteristics of graduates in all aspects. Considered in each aspect it was found that there was significant difference in executives satisfaction with Academic at the 0.05 level among executives in different age. 5. There was no significant difference for executives satisfaction on the มหาวิทยาลัยเทคโนโลยีราชมงคลพระนคร (5)characteristics of graduates in all aspects. Considered in each aspect it was found that there was significant difference in executives satisfaction with Ethics at the 0.05 level among executives in different type of enterprises. 6.There was no significant difference for executives satisfaction on the characteristics of graduates in each aspect and all aspects in different type of business. 7.There was significant difference for executives satisfaction on the characteristics of graduates in Professional Characteristics and all aspects at the 0.05 level among executives in different size of enterprises. 8.There was no significant difference for executives satisfaction on the characteristics of graduates in all aspects. Considered in each aspect it was found that there was significant difference in executives satisfaction with Academic at the 0.05 level among executives in different major subjects of graduates.

The purpose of this research was to study satisfaction level characteristic of graduates expectation and compare satisfaction of Enterprises to graduates in Faculty of Architecture at Rajamangala University of Technology Pra Nakhon. The graduates five skills considered in this study were communication skill learning skill analytical skill ethic skill and technical skill. The sample group selected by a definitely random selection consisted of 30 employer of graduates of Faculty of Architecture who graduated in B.E. 2548. The tool used in this research was questionnaire and the data were analyzed by percentage means standard error of the mean paired-sample t-test independent samples t-test and one-way ANOVA based on the five skills. The research results showed that the expectation of Enterprises to graduates was high level at all skills by the average was 3.90. While the results of satisfaction of Enterprises to graduate was medium level at all skills by the average was 3.36. However the comparative results of satisfaction showed that most skills of the satisfaction are different but the sex of employer type of Enterprises and size of Enterprises was significantly different at level 0.05. Except the age of employer and type of business was not significantly different at level 0.05. The most important reason of Enterprises to employ the graduate was knowledge and competency. The first skill that the employers need was technical skills.

The purposes of this research were to study and compare the characteristics of the school administrators demanded by the teachers under the Bangkok Metropolitan Administration Bangkhuntian in the whole level; and as classified by the gender educational level work experiences. The sample groups contained 340 teachers under the Bangkok Metropolitan Administration Bangkhuntian chosen by a simple random sampling method. Percentage means standard deviation and t-test were applied to the data analysis. The findings were 1) the characteristics of the school administrators demanded by the teachers under the Bangkok Metropolitan Administration Bangkhuntian in the whole level and in each aspect were at a high level especially the aspect of merit was at a highest level. 2) the characteristics of the school administrators demanded by the teachers under the Bangkok Metropolitan Administration Bangkhuntian as classified by the gender educational level and work experiences were not different.

The objective of this study is to experimentally and numerically determine the effect of powder sizes on the void fraction which subsequently affects the heat transfer characteristics of miniature sintered–wick heat pipe usually applied in the notebook computer. The powder size of the wick is a profound influence on the heat transfer performance as well as the economic aspect of the heat pipe. By using computer program to simulate the void fraction of the sintered wick made of two sizes of metal powder and accordingly the mixture fraction of such metal powder the optimum throughput heat transfer of the miniature heat pipe can be predicted. The inputs of the simulation program are size specification the thickness of copper powder and powder fraction. The heat transfer characteristics of the heat pipe will be determined by firstly obtaining the void fraction of such sintered wick. Then the heat transfer rate will be calculated from the void fraction. The optimum void fraction can be solved as the point at which the void fraction and heat rate are appropriate on the basis of economic consideration. In order to validate such calculation the experiments have been conducted with several kinds of metal powders. The wick employs the copper powder with range of diameter of 150 - 212 and 250 - 297 micron respectively by wick molding with sintering process. The miniature heat pipe with outside diameter of 6 mm and the total lengths of 200 mm was used. The wick thickness was fixed of 0.46 mm. Water was used as a working fluid. From the result the heat transfer performance at normal state of the heat pipe with powder fraction of 1 : 3 has found to be as high as 25 W which is quite closed to the predicted one.

This research studies the production of bacterial cellulose from Acetobacter xylinum TISTR 975 with pineapple peel juice a low cost carbon source and coconut water as nutrient and carbon source. The factors influencing the production were studied including incubation time type of carbon sources and ratio of mixed carbon sources. In addition the characteristics of the produced bacterial cellulose were investigated using Fourier Transform Infrared Spectrophotometer (FTIR) Scanning Electron Microscope (SEM) Thermogravimetric Analyzer (TGA) Differential Scanning Colorimeter (DSC) and x-ray Diffractometer (xRD). It was found that the coconut water produced the amount of bacterial cellulose higher than the pineapple peel juice with 10 days of production. An addition of the coconut water into the pineapple peel juice increased the amount of bacterial cellulose. The characteristics of two bacterial celluloses from two different sources were nearly similar but the one from the pineapple peel juice had higher impurities. It can be concluded that the pineapple shell extract could be used as low cost carbon source for bacterial cellulose production.
