This research’s objectives were to develop an energy saving rotary dryer for paddy using hot air recovery system and to evaluate the energy using. Rotary dryer divided rotating cylinder made of 304 stainless steel 2 mm of thickness 39 cm and 200 cm of diameter and length. The inverter was used to control speed of gear motor of 0.5 HP and rotating speeds of 1-3 rpm. The inside of cylinder composed screw and capture flights. The cyclone system was used to dust separating from the system. The moisture trap contained silica gel the outlet hot air was reduced moisture and recovered using. The fiber glass insulator was applied for reducing energy loss. The heating box composed 3 set of 1600 W heaters and blower motor power was 0.5 HP. In the experiment the drying temperature was varied of 50 60 70 and 80oC and cylinder speed was varied of 1 2 and 3rpm (15.66 10.66 and 5.66min of drying time). The initial moisture content of 10 kg paddy was 29.7?0.6 %wb. The result show that the optimum conditions drying temperature and cylinder speed were 70-80oC and 1 rpm (15.66 min) and final moisture content was 9.2-11.8 %wb. From the save energy testing found that the reducing of SEC was 0.4-0.6 MJ/kg water per drying cycle. There for this developed dryer can save energy using

The purposes of this research were to (1) study the needs of teachers and students in Secondary Education Service Area Office 11 in English instruction using mobile electronic devices (m-Learning) and (2) to develop the model of English language instruction using mobile electronic devices (m-Learning) for Upper Secondary Students in Secondary Educational Service Area Office 11. The samples were 222 teachers and 394 students taken from Secondary Educational Service Area Office 11 using a Taro Yamane’s formula with the significant level of .05. The research procedure was divided into two phases. Phase one was the study of the needs of teachers and students in teaching and learning using mobile electronic devices two sets of questionnaires; one set for teachers and one set for students were used to collect data. A model of English instruction using mobile electronic devices was created in this phase. Phase two was the verification of the developed model by the experts. A verification form was used to collect data. Data were analyzed through mean and standard deviation. The research findings were as follows:

The objectives of this research were 1) study about educational achievement in financial ratio of undergraduate of Sripatum University by cooperative learning: numbered heads together. 2) compare the learning achievement in financial ratio being taught by cooperative learning: numbered heads together technique and the Traditional teaching method . The population used in the research was 80 students that enrolled in business finance on semester 1/2012. The population was divided into a control group and an experimental group. Each group contained 40 students. For data analysis mean standard deviation t-test were used. The research finding indicated that the learning achievements of students using the cooperative learning : numbered heads together technique and the traditional teaching method were at variance with statistical significance at the level of .05 whereas the learning achievement of students of the experimental group treated by cooperative learning: numbered heads together was found higher than the experimental group treated by the traditional teaching method.

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.

The research is conducted how to learning and to play chess by making program Computer Assisted Instruction (CAI) to delivery of learning materials and documentation to 1000 schools in area responsible of the Office of The Basic of Education to stimulating activities and learning Thai chess. Exploring the need of young chess players the researcher gathering information by using questionnaire. The quantitative research based on a population sample. The third of the popularity are young people aged between 7-12 years youth aged 12-18 years and young people aged more than 18 to 22 years. The results showed that schools in the north to meet the highest rate of 87.18 percent compared to young chess players do in Thailand mostly young men. The 71.75 percent of the youth in learning to play Thai chess through the ages between 7-12 years old 36.00 percent were in elementary school. The 39.25 percent of the most experienced and know to play is 58.00 percent. The recommendation and comment on the online chess the average levels of good. The people who had experience after playing online chess score average level of very good. Which indicates that playing thaichess through learning this research has been used to do chess players and much wider. Improve playing skills. Be the number of ideas and Thailand culture in the young group of players.
