This research aim to study process methods of the operation of pig farmer know ledge and understanding in application of accounting software of pig farmer group. Analing of problems and obstacles and factors that lead to success (success factor) of using accounting software. Sample are willing to give (provide) accounting information and apply for accounting software found that process method of the operation of pig farmer by chosen the healthy breeder and sire. After that take the breeder and sire which are selected to mating take care and nurturing of the 4 months pregnant breeder. After the birth of pigs take it to pigsty for 25 days. After that move them to the fist sty for 30 days and move them the second stay for 95 – 100 days. The application of accounting software could save data and evaluate from financial report and more convenience farter it suitable (collect) for decision making on time and valuable. Problem and obstacle are 1)Lack of knowledge to pig farmers about basic knowledge of computer. 2) The limitation of software is complicated The suggestion of this research is should be trained personnel to achieve specialization.

This research was a study of energy management in public building. The goals of this project are to decrease energy consumption and to enhance energy management system of the building. Regarding the energy survey the building lights are turned on for 24 hr. per day in order to satisfactorily serve the customers. In the study it was found that the energy consumption of electric light on the fourth floor roof can be reduced by changing the light “Floodlight MH. 4x250W” to be “High bay LED 4x150W” For the merit this project can save the energy around 6632570 baht per year and switching towards high-efficiency lanterns and replacing FL. T8 light bulbs installed in the walkways with FL. T5 models. This reduces lighting cost by 361425 baht per year. Moreover the energy management system was analyzed by using SWOT Analysis. As a result we observed the barriers to communication must be overcome to promote energy conservation. One approach is to increase the performance through the use of communication strategies within organizations. This method will help align employees understanding and participating in activities of conserve energy.

This paper presents a design of the control system to control AC/DC converter. Algorithm of a control system design consists of the output voltage loop control used a fuzzy gain scheduling of PI control and the current loop control used a hysteresis control which is described in this paper. The evaluation of the proposed control system is used to control an isolated CUK AC/DC converter operation with a 250W load and a -48V output voltage. The system is achieved as the following; the tight output voltage both the steady state operation and the transient response a power factor is nearly unity and the waveform of input current is nearly sinusoidal. In addition the control system design is simple and uncomplicated

The objectives of this study are to develop a management system for examination bank and an online examination. Working procedures were performed by analysis a traditional working system and problems study of user requirements design of a new working system and a development of the new system. PHP and JAVA programming language operating with MySQL for developments and a database management were used. The new system consists of 6 systems by operating as web application. Users are 3 groups that are teachers students and administrator. In the items analysis stem a reliability value was calculated using KR-20 and KR-21 of Kuder-Richardson. The level of difficulty and discriminating power were identified using choice analysis with 27 percentages of upper and lower technique. The new system was tested with 3 groups of teachers students and administrator. The evaluation was performed using questionnaires. The results of the evaluation shown the contentment is in good level. Accuracy of the system was measured by comparison between a traditional item analysis and the new system. The comparison results were not different. However the accuracy of item analysis results depends on knowledge of the students who are in testing.

This experimental research was to test a performance of flat-plate solar collectors using biodiesel as a working solution with a solar thermal system. The purposes were to promote a biodiesel use as an alternative fuel for higher efficient heat energy and as an added renewable energy for a production process and to provide a guideline in education and for development in the future. The experiment was to test a performance of flat sheet solar collectors using ASHRAE STANDARD 93-2003 and to test a thermal potential of 12 litres by volume of biodiesel in a 2 m2 flat- plate solar collector used as heat source of the system. Thus biodiesel was used as a working solution with a flow rate of 2.4 litre per minute and the test duration was between 09:00 am. and 03:00 pm. The result revealed the performance values of the flat-plate solar collector used in this experiment as FR( ) = 0.958 and FRUL = 15.02 W/m2K. The temperature of biodiesel in the solar thermal system increased from 33๐C to approximately 80-90๐C varied with solar radiation values. However; the mentioned degrees could be efficiently applied in biodiesel production process as a main heat source or a supplemental heat source depending on appropriate variables.
