This research study is a combination of quantitative research and qualitative research. The objectives are: 1) study the present conditions and barriers 2) preparation 3) factors that effect to the preparation 4) find the ways to prepare 5) form to prepare and 6) the format to prepare in ASEAN. There are two types of administrators namely administrators teachers and staff who related to the quantitative data of 285 sets of questionnaires. To collect and analyze data already processed with statistical program R to determine the frequency percentage mean and standard deviation and qualitative information to select 20 people of administrators teachers and staff then verify the accuracy of the content with content analysis. The results showed that the current problems in education: 1) A curriculum does not support the needs of ASEAN community 2) Premises is inadequate and not ready in education management 3.) budget is not enough In the preparation of education management to enter the ASEAN 4) lack of person who in charge of education management 5) Material is inadequate in preparing the study for the ASEAN community. The preparation for ASEAN community 1)to practice English 2) to prepare teachers to enter the ASEAN 3) researchers who are ready to do the research to develop education management 4) sufficient staff are available in English teaching 5) to prepare the budget usage for the ASEAN 6) executives with expertise in education management determinant factor for the promotion of education in preparation for the ASEAN community. The overall image is moderate. The SWOT analysis of strengths and weaknesses is high level. The guidelines of educational policies for ASEAN community is at high level the budget has been prepared adequately for the preparation of education in the ASEAN community is at high level. For qualitative information is about the Rmutp. policy in 4 M. [ man money management and marketing ] for education. There is not ready yet to prepare the English course of nine faculties must train both of teachers and students in English to welcome ASEAN community for being attract the Thai students and foreign students in ASEAN countries.

Normal norms of the physical fitness level of male volleyball players were as follows: 4.1 Front bending: very high level matches with the T-score above 61 high level at 55 - 60 moderate level at 45 - 54 low level at 40 - 44 and very low level below 39. 4.2 Standing and jumping: very high level matches with the T-score above 61 high level at 55 - 60 moderate level at 50 - 54 low level at 45 - 49 and very low level below 44. 4.3 Sitting-up for 30 seconds: very high level matches with the T-score above 60 high level at 55 - 59 moderate level at 45–54 low level at 40–44 and very low level below 39. 4.4 Running and Picking up objects: very high level matches with the T-score above 61 high level at 55 - 60 moderate level at 45 - 54 low level at 40 - 44 and very low level below 39. 4.5 Running for 50 meters: very high level matches with the T-score above 60 high level at 55 - 59 moderate level at 45 - 54 low level at 40 - 44 and very low level below 39. 4.6 Harvard Step Test: the Physical Fitness Level of male volleyball players was in moderate level. Ten players (66.67%) had the index of the physical fitness at 50-80; the other 5 players (33.33%) were at a very low level that is the index of physical fitness was below 50.

The objective of this research is to study the suitable factor level for the improvement of annealing furnace for rolled coils steel sheet. The experimenting has been performed to find suitable oxygen level by 5 annealing furnace experiment. The research has been started by collection the combustion. After that the burning adjustment by changing combustion technology with 5 levels of BGCV control valve open as 23% 40% 50% 75% and 100% has been implemented. The combustion adjustment data are recorded analyzed and compared with incomplete combustion value. The research result has been found that after improvement the combustion value. The percentage of oxygen level are improved to the better quality which standard at MV0-49% equal 2.5-4 O2% and MV50-100% equal 1.5-2.5 O2% conclusion 1 furnace as follows at the MV23.1% MV40% MV50% MV75% and MV100% level of oxygen as 2.5% 3% 3% 2% 1.5% and level of carbon monoxide as 0 ppm 2 ppm 2 ppm 2 ppm and 0 ppm respectively. Resulting of fuel energy consumption in the annealing process has been reduced around 225608 baht /year/furnace. Therefore it can depict that energy saving and annealing furnace efficiency improving are increased. The modified parameters will be applied to be the new standard reference values for the further engineer’s operational manual.

The objective of this research is to study the combustion characteristic of a low-pressure vertical port burner using computational fluid dynamics (CFD). The simulation model was created using Fluent 6.3 in 3D-model of the same size of the burner. The CFD results were verified by measuring the temperature around the burner head and a vessel. Moreover the results of conventional vertical port burner having the swirl angle of 90o and the inclination angle of 90o (CB-S90I90) and two swirl port burners (SB) being SB-S90I13 and SB-S30I90 were compared. The temperatures obtained from CFD and experiments were similar which the error was less than 9%. From the CFD’s results the temperature and heat flux of the SB-S90I13 burner were higher than those of the CB-S90I90 burner. The maximum temperature and heat flux of SB-S90I13 burner were 1445 K and 5291 W/m2 respectively. It was implied that the combustion characteristic and heat transfer to the vessel of SB-S90I13 burner was better than that of CB-S90I90 burner. It was resulted that the thermal efficiency of SB-S90I13 burner was better than that of CB-S90I90 burner which was the percentage energy saving of 6.93%.
