This study aimed to examine the identity of the community towards sustainable tourism development and in order to set an appropriate management guideline in environment and energy conservation in Klongkone Community Mueng District Samutsongkhram Province. The data was collected using in-depth interview of Homestay owner Village Headman and government sector for 10 person. It was found that homestays do not have standard of homestay arrangements. Due to lack of knowledge of hotels and services and lack of policies to conserve the environment and energy in the homestay that is clearly visible. There is only behavior in saving of energy and reduction in energy consumption to reduce expenses incurred in business operations.

The objective of the research is to identify the problems and needs in developing the English communication skills in the workplace of front office hotel staff in Nakhon Ratchasima province. The sample of the study are 420 front office hotel staff in management and operational level selected by using the area random sampling. The data collection approach employed in this study was mix method both questionnaire and interview. The collected data were then analyzed and compared by using frequency percentage mean and standard deviation. The findings were as follows: 1. Four English language skills (listening speaking reading and writing) are essential for all staff and listening is considered as the most important followed by speaking. 2. The main problems of using English in the workplace are writing and reading due to lack of confidence unfamiliarity with the grammatical structure and vocabulary. 3. All staff are desirable to develop English communication skills especially speaking and listening in different situation duties and responsibilities.

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.

Carbide Insert efficiency development of this research equivalent to standard insert type : SEKN1203AFTN. For the higher operating efficiency is the machining time by the tool life increased for rough machine of face milling machine. Flank designed to have a flow slot coolant flow rate of coolant to have a incrased convenient flow as a result the surface and cutting edges less heat. The machining ability is different compared to the unslot in flank. The flank slot reduces the contact and slot which to have coolant flow and friction force milling machining. As a result the milling time was 26.31% the vibration was reduced by 35% and the workpiece surface Roughness was reduced 62.79%. As a result to development the phototype product is performance in using and cutting edge increased. It can be apply in using Cement Tungsten Carbide in sustainable industries.
