Currently transport has played an important role in everyday life resulting in huge traffic jams caused by big city streets and pollution problems from global warming to global temperatures are rising. Since humans are creatures that prefer comfort in all areas which contrasts with the higher temperatures of the Earth. Currently the use of air conditioning a lot. To modify the temperature is reduced in the range 2 3 to 25 degrees Celsius makes people feel comfortable. However the use of air conditioning in the car cabin cooling efficiency can be increased to a higher level than it is by cooling the refrigerant. The aim of this research is to test and compare the performance of car air conditioning systems usually equipped with a heat exchanger. Using water from the condensation of evaporator as a medium for heat transfer. By installing the equipment at the outlet of the condenser. This causes the temperature of the refrigerant is low. The pipe lengths in the equipment from the calculation of 1 .2 meters and copper lines that increases the length of the tubes was calculated to compare with a length of 1.6 meters to test the speed of the compressor 1000 1500 2000 and. 2500 rpm and a wind speed of 20 35 and 50 kilometers per hour. The results of experiment found that the temperature refrigerant equipment decreased from an average of 1.6 degrees Celsius the pipe length of 1.2 meters and 1.6 meters of pipe temperature drops 1.8 degrees average temperature attended Eva sufficiently reduced operator. It increases energy efficiency ratio averaged 6.68% of the pipe length 1.2 m and 22.24% at a length of 1.6 meters as well as to increase the coefficient of performance of the air conditioning system. 6 .6 9 % of the pipe length of 1.2 meters and a length of 1.6 meters at 22.4% with the key factor in optimizing the cars air conditioning system. Making the refrigerant from the condenser the temperature drops to pull heat out of the cabin through evaporator higher.

The purposes of this research were to: study performance efficiency of Kasikorn Bank employees; to compare personal characteristics and performance efficiency of Kasikorn Bank employees; and study correlation of employee competencies to performance efficiency of Kasikorn Bank employees. The questionnaire and test were employed for collecting data from the sample group comprising 287 cases of Kasikorn Bank employees at Ratburana head office. The sample group was derived from simple random sampling. The frequency percentage mean standard deviation T-test one-way ANOVA and Pearson’s correlation with statistical significance at the level of 0.01 to 0..05 were applied for data analysis. The findings revealed that the majority of participants were female; aged between 18-30 years; working years were five years or more; and their position was unit chief. The result of difference comparison found that different genders ages and working years had no different effect to performance efficiency. Moreover correlation between employee competencies and performance efficiency of Kasikorn Bank employees it was found that correlation was at high level and the same direction.

The objectives of this research are to study factors affecting the sustainable success and define the key performance indicators. The research instruments used for data-gathering were semi-structured interview. The results of the interviews were created by using independent variables in questionnaire. The populations of this research are the 54 fast dining business entrepreneurs within 500 metres around the Thawes Area. The information collected by 54 questionnaires with a 100% response rate and analyzed and processed by computer. The results were as follows : There are three main factors affecting the sustainable success of the fast dining business in Thawes area which are internal operation social responsibility and environmental responsibility. Internal operation composed of reasonal pricing fast services constant tasty great hospitality and always keep a good standard. Social responsibility consisted of fresh ingredients cooking process with heath concerns clean kitchen pricing display and following the law of minimum wage employment hiring. Environmental reposibility are include using uncontaminated seasoning reliable source of food ingredients non-toxic cooking material unexpired seasoning and safe tableware and food container. The result can lead to 10 key performance indicators. It’s include customer satisfaction towards services customer satisfaction on the constant taste customer satisfaction on resonable pricing customer confidence in food standard customer confidence in freshness of food ingredients customer confidence in the cleanliness of food customer confidence in the cleanliness of cooking material and kitchen customer confidence in clear pricing display employees satisfaction on their wage and customer confidence on the safety of food. The suggestions were that the entrepreneurs should improve their business to earn more profit and train their employee for a successful service. Related educational Institution and government sectors must be coordinated to develop entrepreneurs in fast dining business to maximize ability for a sustainable success.

This research aimed to find the possibility of increasing the efficiency of the split type air conditioner by using the cool air from a ventilation fan in the air conditioning room for cooling the condenser. Two simulation rooms size 120x120x200 centimeters were constructed. The first room was installed the evaporator and the second room was installed the condenser and a ventilation fan in the lower part of the air conditioning room to deliver the cool air for cooling the condenser. Then the system was tested and compared the energy efficiency ratio and the reduced power consumption between turning on and turning off a ventilation fan. The results of the proposed air conditioner system observed from the various load conditions at 0% 30% 60% and 100% The surrounding temperature of the condenser ranged in 30C 40C and 50C It was found that the energy efficiency ratios increased in the range of 2.94% to 5.92% and the power consumptions decreased in the range of 4.56% to 12.5% The possibility of increasing the efficiency of the air conditioner system by using the cool air from ventilation fan in the air conditioning room for cooling the condenser was verified by the increased energy efficiency ratios and the reduced power consumptions.

Nowadays Eye Tracking Technology is one main challenge for developers of new human-computer interface. This technology provides a more natural way of interacting with a computer system by user’s eye. Now commercially available systems exist; however they are not widely used because of expensiveness. This paper describes a tutorial that shows step by step how to build a low-cost eye tracker using eyeglass setup. The glasses are designed to work with video-oculography technique (VOG) in the infrared spectrum. The key features of the eye is a center of the pupil. The gaze point of users are estimated based on order polynomial regression (linear quadratic and cubic). This research conducted an experiment with 30 participants tested eye-gaze calibration. Consequently the experimental results showed that eye-gaze can be estimated in real-time while the cubic function can be accurate eye-gaze position more than the other function.
