กรอบงานบนพื้นฐานของภววิทยาในฐานะที่เป็นพื้นฐานของระบบสารสนเทศสำหรับสร้างคำถามแบบปรนัย

This research is aimed to propose an ontology-based framework for generating multiple-choice questions that can evaluate students’ knowledge in the analytical level. The questions generated from this framework could encourage students to apply relative concepts from the lesson they learn to produce different paradigms for solving the same problem. The experiment of this research demonstrates an implementation of the framework. A structure of a question set from the framework comprises a problem and an initial solution in the question phrase and multiple choices including one correct choice and three distractors. The experimental results show effectiveness of the questions constructed based on this framework in terms of distractors that can reveal students’ misconceptions. Also difficulty and discrimination indices – P-scores and D-scores used in the experiment show that in a range of difficulty the generated questions can reveal strength and weaknesses of students in the groups of high and low learning performance. Eventually this research suggests how the proposed framework could be used as a foundation for automatically generating questions in a knowledge-evaluation system.

The objective of this research is to study the development of eco cars using power-cutting mechanism technique of Transmission System. Two eco cars had been studied. The first car was conducted with the aim of developing transmission system and clutch system by changing from gear drive transmission system and chain drive mechanical clutch to belt and pulley transmission system by new designing the belt and pulley transmission system to have propeller shaft as the device to transmit power from the right to the left side with bearings to help reduce friction. Pulley system and clutch lever were installed in which the newly built clutch can be controlled by driver. The new model of transmission system is weight 0.7 kg which is lighter than the previous weight of 0.8 kg. Based on the first testing by participating in the 22nd Honda Eco Mileage Challenge at Chang International Circuit it was found that the system with belt tension at 1 kN resulted in good performance of transmission system and clutch system with fuel efficiency value at 626.157 km/L. After that the belt tension was adjusted and set up at 1.1 kN for 3 tests at Solar Track Thailand and it was found that the maximum fuel efficiency value was 1061.18 km/L at the speed of 34 km/hr. The second car was improved in transmission system suspension system steering system and also engine. The first trial was experimented on the 22nd racing event at the Chang International Circuit where this fuel efficient prototype car could run at 18 km. The result showed that it could have good mileage which was 275 km/L. After improvement the car was tested again for three times at the Solar Track Thailand circuit where it ran at 16 kilometers. The result revealed that the best saving was equivalent to 613 km/L at the speed of 30.6 km/hr.

Vegetable Growing System has an absolute requirement of nutrients and minerals. The microbial application can facilitate in addressing limited access to chemical fertilizer concerns. Moreover the photosynthetic microorganism community can contribute together in nutrient availability for plant growth. This research aims to develop an automatic hydro-organic vegetable growing system. Moreover the analytical of photosynthetic microorganism growth rate in fermented juice was also observed within three months in terms of temperature pH electroconductivity total dissolved solids mixed liquor suspended solids and phosphorus. The efficiencies of an automatic hydro-organic vegetable growing system were also monitored along an experimental period (45 days of operation optimization). The vegetable growth rate was observed in terms of leaf length leaf width and root length. These experimental results showed that the phototrophic growth of photosynthetic microorganisms should the main bacterial activity at daytime operation and vegetables could grow by using fermented juice. The photosynthetic microorganism concentration and nutrients concentration in fermented juice was significant to promote the productivity of vegetable growing which the photosynthetic biomass is rich in proteins and vitamins. Besides this system can be easily applied and also very cost-effective for agricultural practice and frequent maintenance every experimental run was necessary.

Application creation of Petch Nam Sap community enterprise management system Phetchaburi to create application for Petch Nam Sap community enterprise management system To assess satisfaction with community enterprise management system applications using PHP5 HTML5 CSS3 phpMyAdmin to design databases and image editors as a tool for system development and use questionnaires to assess satisfaction with applications. The samples used in the experiment were Ban Nam Sap community. The application created makes the operation more convenient. Data is stored and managed within community enterprises. Statistics using average percentage research results showed that Petch Nam Sap community enterprise management system application Phetchaburi province generated an average efficiency of 4.64 at the highest level. It helps to manage the information of community enterprises. Evaluation of satisfaction with Petch Nam Sap community enterprise management system application. The average deviation of 0.49 is the highest. It shows that the Application for Petch Nam Sap Community Enterprise Management System It can be used in Phetchaburi.
