The objectives of this research were (1) to develop food ordering system on ipad for Huapla Chongnonsea Restaurant to meet the demands of both administrators and users and(2) to study satisfaction with the system ot administrators and users in terms of aesthetic and usability of the foof ordering system on iPad. The system development was diveded into two parts. The mobile application on iPad was developed with Objective-C and used XCode as developing tools with SOLite as the database management system on iPad. An application on server was developed with C#.NET and used Microsoft Visual Studio 2010 as developing tools with Microsoft SOL Server 2008 R2 as the database management system on server. The purposively sampling group consisted of 2 administrators (manager and cashier) and 10 users (customers of the restaurant). Results from the trial and evaluation of the system showed that administrators satisfaction in aesthetic aspect was in a very high while satisfaction in usability was in high level.On the other hand users satisfaction in aesthetic and usability was in high level.

This research studied combined toxicities of 4 generally found Polycyclic Aromatic Hydrocarbons (PAHs) - anthracene fluorene fluoranthene and phenanthrene – during growth of 3 legume seedlings - cow pea mungbean and longbean - planted in varied combination of PAH contaminant in soil. Results showed that mungbean growth was more sensitive to PAH co-contaminated soil than cow pea and longbean. Co-contamination of all 4 PAHs was more toxic to legume than each pair of PAHs. Shoot length and fresh weight of legume seedling were more sensitive to co-contamination of all 4 PAHs than root length. Dry weight of legume seedling was the least sensitive to co-contamination of all PAHs.

This research aims to develop software defect tracking and management system for faster performance of software development team. The proposed system will allow the team to interact with each other more effectively in each software project which can lead to better communication and minimal misunderstanding. The advantage of the research is to simplify the software defect tracking and management system. Software development team who works in medium software company was interviewed to gather requirements of the system. Agile methodology was used in the system development process. Evaluation of the developed system was performed through test cases and users satisfaction. Results of the research indicate that the development team was satisfied with this system in high level. Furthermore this system could reduce the duration of defect tracking and management by more than 15 percent. However online user manual should be provided for faster study and practice with the system.

This paper proposes a new method for XML compression called XML Zipping and Querying (XZAQ) which can compress a regular XML file and query the compressed XML file without doing full decompression. XZAQ is based on non-homomorphic method which does not preserve an interleaving between an element structure and data content. XZAQ is implemented by using grammar-based method to encode an element structure and to maintain links between the element structure and the data content. XZAQ can partially decompress a block of compressed data in order to support querying of XML data. From the experiments XZAQ had an average compression ratio of 70 % smaller than original size. It also provided better compression ratio of 10% less than XGRIND. Moreover XZAQ could support either exact-match or range in both simple and complex query types whereas XGRIND could provide only found or not found match

The objectives of this research were to study the context of an information system for University’s Administrators of Ubon Ratchathani Rajabhat University to develop an integrated information system for University’s Administrators and to evaluate the developed system. The sample of the study included 24 administrator members and 7 officials at the Office of Ubon Ratchathani Rajabhat University. The research instruments were sets of interviews and questionnaires. Data were analyzed by content analysis mean and standard deviation. The study revealed that the information technology has been used in the department of Ubon Ratchathani Rajabhat University but the development is independent are there is a problem in report retrieval for university administrators. This study has developed an integrated system of information for university administrators by creating a data warehouse and establishing a connection between the data warehouse for each database. Data are stored in the data warehouse through data filtering of each daily segment in order to create a report for information which is accurate and running on network. The research results revealed that integrated information system for university administrators allows users to run a report according to the desired information quickly and easily. The evaluation of satisfaction and acception is at a high level a value of average is 4.40 and standard division is 0.55.
