This is an independent study on greenhouse gas emissions and ways to reduce them. A five-star resort in Koh Samui Surat Thani province has been used as a case study. The study used digital tools to gather information on activities that cause greenhouse gases and energy consumption at the resort. The calculation of carbon footprint is in line with the guidelines of the Thailand Greenhouse Gas Management Organization. Digital systems help data collection and carbon footprint analysis and this is best done at set intervals. For example digital systems can monitor power consumption every 15 minutes measured in real time. The carbon footprint maximum emission each day occurs between 2.00 and 4.00 pm the peak time of energy consumption. Use of electricity is the activity that produces the highest amount of greenhouse gases at a total volume of 4215.1 tonCO2-e per year or 88.12% of the total activity. LPG gas consumption produces the second largest volume of greenhouse gas emissions at 412.8 tonCO2-e per year or 8.63% of the total activity. From January to December 2017 the carbon footprint emission is 4783.5 tonCO2-e and the average emission per room night is 4.2 tonCO2-e. The study found that a 10% reduction in energy Consumption could reduce greenhouse gas emissions by 421.52 tonCO2-e per year or 0.4 tonCO2-e per room night.

The objective of this research improve the taxation process service KhunKaew Subdistrict Municipality Office. Quality Function Deployment: QFD is found that the standard of period operating time should be resolved by applying the principle of improving ECRS that reduce the working time of Property tax collection process. There are 6 steps of the testing process and finding the standard time with the 10-cycle times to find out about appropriate number of cycles using the Maytag table at 95% reliability and ±5% precision. The results are found that the appropriate of 13 sub-tasks number cycles times and no more than 10 cycles. Then use the average time to find out determining allowances time for determine standard time. The results after applying the ECRS principle to improve and solve problems in sub-work are found that it can reduce the number of sub-work from 13 works to 11 works and also can reduce the cycle time from 1168.88 seconds down to 633.68 seconds or 45.74%. There are reduce wasting of working process waiting times duplication of work. The result could be applied with another tax collection the similar methods and could be responses the customer requirements.

The objectives of this study is to increase efficiency of steam boiler 2.5 ton per hour which used liquid petroleum gas LPG as fuel. bringing heat recovery inside boiler chimney stack to preheat feed water with technology heat Exchanger Economize. Taking the economizer with its pipe length of 1000 mm and 62 mm diameter for 64 pipe is a cross flow with staggered tube to increase water temperature before entering the boiler pass to deaerator The study is carried out to compare the differences and savings of the feed water temperature steam boiler efficiency and fuel consumption between having the economizer installed and uninstalled. reference to study The result after installed the heat exchanger economizer the feed water is passed into steam boiler deaerator higher temperature from 38.30°C to 67.20°C which leads to increase efficiency of steam boiler from 81.59 % to 85.65 % meaning that the fuel consumption of steam boiler will be reduced 4.97 %

The study aims to study the change leadership that affects the organizational culture and work efficiency of the staffs at the operational level and to study the good governance principles that affect the organizational culture and work efficiency of operational staffs at Commercial Concrete Production Business Unit. The population used in the study is 200 operating staffs at Commercial Concrete Production Business Unit using questionnaires for data collection. The data analysis is conducted using descriptive statistics and inferential statistics. The result indicates that change leadership affects organizational culture of operational staffs with statistical significance at 0.05 level. It can predict the organizational culture of operational staffs at 16.30 percent. Good governance principles affect the organizational culture of operational staffs with statistical significance at the level of 0.05. It can predict the organizational culture of operational staffs at 29.50 percent. Change leadership affects the operation efficiency of operational staffs with statistical significance at the level of 0.05. It can predict the work efficiency of operational staffs at 13.80 percent and good governance principles affect the work efficiency of operational staffs with statistical significance at the level of 0.05. It can predict the work efficiency of operational staffs at 28.70 percent.

The objectives of this research were to study 1) the marketing mix factors of choosing derlers of Japanese imported wind instruments 2) consumer loyalty of choosing derlers of Japanese imported wind instruments and 3) to study the influence of marketing mix factors in choosing derlrs of Japanese imported wind instruments. The sample group was 240 consumers who chose to use sales representatives Japanese imported wind instruments. The questionnaire was used to collect data in the metropolitan areas. The data were analyzed using statistics including frequency percentage mean standard deviation and multiple regression analysis which was applied to test the hypothesis. The study result indicated that most respondents were males aged between 31 - 40 years old working as engineers earning monthly income averaged between 20001 - 40000 baht. The marketing mix factors of Japanese imported tools dealers in terms of the distribution channel was considered highest followed by the price process personnel product physical characteristics and the marketing promotion respectively. Regarding the consumer loyalty in choosing Japanese imported wind instrument dealers the highest was word of followed by the price sensitivity purchasing intention and claim behavior respectively. The hypothesis testing reveal that the marketing mix factors in terms of price did influence the loyalty in all aspects namely word of mouth purchasing intention price sensitivity and claim behavior. Therefore the hypothesis was accepted. The marketing mix factor related to product had no influence on loyalty in every aspect such as word of mouth purchasing intention price sensitivity and claim behavior. Therefore the hypothesis was rejected. The marketing mix factor related to the process and price that influenced the consumer loyalty towards word of mouth in choosing dealers of Japanese imported wind instruments. The marketing mix factors related to price sales staff and distribution channels influenced the consumer loyalty in choosing dealers of Japanese imported wind instruments. The marketing mix factors related to price sales staff and process influenced the consumer loyalty and price sensitivity in choosing dealers of Japanese imported wind instruments. The marketing mix factors related to the physical characteristics price and marketing promotion influencing consumer loyalty claim behavior and promotion in choosing dealers of Japanese imported wind instruments.
