The purpose of this research is to study the level of knowledge and understanding in democracy of the youths in Bangkok according to gender age education level family incomes occupation of the parents interesting level in political news and the participation in political activity. This research is a survey research. The sample groups are the 2500 youths who live in Bangkok metropolis persons from 50 districts by accidental sampling. Questionnaire is used as a tool in data collection. The statistics are means of percentage frequency arithmetic means standard deviation and Chi-square. The results are as the following: most of The have knowledge and understanding level in democracy at a moderate level. The factors affecting the knowledge and understanding which a statistical significance at .05 are age education level family incomes occupation of parents interesting level in political and participation in political activity.

The aim of this research was to study the status in using information technology in education of level 3-4 teachers in schools of the Office of Bangkok Education region 3 academic year 2004. The sample were 362 teachers. The instrument used in this research was the questionnaire. The data were analyzed by Percentage frequency means standard Deviation and analysis of variance. The results of this research were as the following: the status in using Information technology in education in all seven dimensions: CAI distance learning internet education network classroom laboratory and software application of teachers was at the medium level.

Now a day the mostly air condition are use the air for reducing the temperature at the condenser unit. Moreover many dusts are adhering in area of fin coil. From this reason the heart reduction efficiency is decreased and increasing the energy consumption. Thus the aim of this research is to design the finned-tube condenser unit cleaner machine for increasing the heart reduction efficiency. From the results of experiment it found that the finned-tube condenser cleaner machine is desirable when comparing with the performance before used. By the original performance the refrigeration effect coefficient of performance (C.O.P) and energy efficiency ratio (EER) is 34179 Btu/hr 2.62 and 8.9 Btu/hr.Watt. On the other hand the refrigeration effect (C.O.P) and (EER) is 39766 Btu/hr 3.12 and 10.7 Btu/hr.Watt respectively when the condenser unit cleaner machine is used. Based on this condition the value of the refrigeration effect and (EER) are increase to 16.35% and 19.19% respectively. Thus the heart reduction in condensing unit can be aided the performance and prolong the life time of air condition by depending on the cleaning of condensing unit.

At present business globalization is highly competitive and so is hotel business administration. Therefore to maintain effectiveness and growth in hotel business administration appropriate strategies must be implemented especially in human resource management in order to enhance the personnel to effectively work up to their potentials. Knowledge management or KM is considered one of the best strategies to be introduced in hotel business administration. Conceptually stated KM aims at extracting tacit knowledge by using knowledge skill attitude and experience from the human resource in operation to create the viable learning organization in hotel business.

This object of research is to compare the computation solution of two numerical methods. The methods were Jacobi iteration method and Guass-Seidel iteration method for the stickslip problem at die of the extrusion process. The Navier-Stokes equation was analysed by finite element method of semi implicit Taylor-Galerkin/pressure-correction scheme to approximate velocity and pressure for Newtonian fluid in two dimentional cylindrical coordinate system. Solution accuracy was improved by the gradient recovery technique. The convergence analysis revealed that Guass-Seidel method approach to exact solution was better than Jacobi iteration method that is because Guass-Seidel iteration method had less solution than Jacobi iteration method.
