This research is to study in heat transfer of hot water tank from an air conditioner which is a cylinder type and has a hot water pipe around the tank. It is used for finding a position and a pattern of distribution of the hot water pipe around the tank in the highest heat transfer condition. The study uses the cylinder of hot water tank filled 45 liters of 25 oC water. An experiment separates in 3 positions of pipe wrapping which are the bottom the center and the top of the tank. Then 80 oC of hot water run thought the hot water pipe which is wrapped around the tank for 120 minutes. The result of the experiment shows that tubing position that causes the highest heat transfer is at the bottom of tank. Pipe wrapping at the bottom of the tank has the heat transfer higher than the top of the tank at 30%. Furthermore this experiment studies in spacing of hot water pipe. There are 3 types for testing which are spacing hot water pipe as one time two times and three times of diameter of pipe. The result illustrates that spacing the hot water pipe can significantly increase the heat transfer. The heat transfer of spacing the hot water pipe in three times of diameter of pipe is higher 5.8 % than spacing in one times. In addition this research is to study in the effect of turbulent flow on the heat transfer by installing agitator in order to stir water in the tank. The result is that water stirring in the tank for increasing the heat transfer is not effective for investment because the energy using for stirring is higher than the enhanced heat transfer

This project presents the design and development of application software of retail management system for drinking yoghurt. The developed application runs with Client/Server processing on Windows XP or higher. The objective is to be convenient for checking products automatic adding/removing products in warehouse counting stocked products and editing data. Tools used in development are Microsoft SQL Server for database management Visual Basic Version 6.0 for application development and database programming and Crystal Report 8 for creating reports and invoices. The developed application can enhance the effectiveness in retailing for drinking yoghurt properly.

The study of Best Budgeting Management and Performance of Small and Medium Enterprises in Bangkok has an objective to study the best budgeting management of small and medium enterprises. A sample of this study is 250 accounting executives of small and medium food production enterprises in Min Buri district. The factors to evaluate the best budgeting management include operational planning perspective work coordination perspective work motivation perspective and operational controlling perspective. Performance factors consist of customer perspective internal process perspective learning and development perspective and financial perspective. The data are evaluated and analyzed by package program to find the percentage mean standard deviation test the difference of opinion of accounting executives who are in small and medium food production enterprises by using t-test and f-test and find the relationship of the best budgeting management toward performance with a statistical significance of 0.05. The result of this research showed that the accounting executives who had different bio-social characteristics had the level of opinion to overall performance differently. The accounting executives who had different age number of employees and operating revenues had the level of opinion to overall performance differently. The accounting executives who had different level of education operating capital number of employees and operating revenues had the level of opinion to performance in term of customer perspective differently. The accounting executives who had different age work experience number of employees and operating revenues had the level of opinion to performance in term of internal process perspective differently. The accounting executives who had different number of employees and operating revenues had the level of opinion to performance in term of learning and development perspective differently. The accounting executives who had different number of employees and operating revenues had the level of opinion to performance in term of financial perspective differently. The correlation testing of regression coefficient of best budgeting management and opinion about performance showed that there was a linear relationship with independent variables at the level of statistical significance of 0.05 and there was able to create a linear prediction. The variable that can predict performance of small and medium enterprise was the best budgeting management in term of operational planning perspective work motivation perspective and operational controlling perspective that can predict at 41.40 percent. While the unrelated variable with performance of small and medium enterprises was best budgeting management in term of work coordination perspective

This project presents the development of wearable device for logging cow behavior using IoT technology. This project aims to develop the device that can collect the cow’s behavior and to identify the current position of cow. The accelerometer and ultrasonic sensors are used to measure walking behavior and sitting behavior respectively. The current position of cow is measured by GPS module. The measured data will be shown and stored in IoT platform. According to the experiments the developed systems can measure the behavior properly with human acting as a cow. Moreover the developed system can show the current position of the cow and message when the cow is out of area. In the future it is planned to implement the developed system with the actual cow in real situation

The study and development to design mushroom nursery for installed within the orphanage cultural school (Main 67) Lao PDR. Is a research to promote and develop the production of raw materials for cooking in the school. Consequently the school has a policy to promote plants and raise animals to prepare food for students. But the amount of the produce is not enough to meet the demand for consumption of students. Therefore the researcher has the idea to design a mushroom nursery that is suitable for for installed within the school. Because the cultivation of mushrooms in the nursery is not difficult and still produces all year round. If there is promotion of mushroom cultivation in addition to plants and animals. Will make the school have raw materials that variety and enough for use in cooking for students. Which will result in students eating more complete categories. By the method of conducting the research beginning with the study and analysis of data to find the amount of mushroom cultivation suitable for the consumption needs of students. After that the study and development of the form of mushroom nursery that is suitable for the use and maintenance. Can be easily assembled and installed. Use materials that can be found locally and use a small budget. According to the research the mushroom nursery is a semiautomatic 3.27 x 8 meters consisting of modular system. By using bamboo and plastic mesh as the main material and inside using the method of placing suspended mushroom bags. Suitable for installation in most schools. Since it can be easily assembled and installed with materials that can be purchased locally. It is also easy to use and maintain. This nursey can produce approximately 2400 mushrooms or about 240 kilograms per month. In summary The study and development to design mushroom nursery for installed within the orphanage cultural school (Main 67) Lao PDR. It is the development of vacant spaces within the school to be agricultural areas that will benefit the school in many ways. Both the quantity of produce and nutrition budget and career promotion.
