Nowadays, many interface devices or training systems have been developed with recent developments in IT technology but only a few training systems for developmentally disabled people have been introduced. In this paper, we present a real-time, interactional and situational training system based on augmented reality in order to improve cognitive capability and adaptive ability in the daily life of developmentally disabled people. Our system is specifically based on serving food in restaurants. This augmented reality based system provides them to experience various different situations safely and take the training session as much as they want under any circumstances. When they use our system, they are able to look around with Head Mounted Display(HMD) and take training sessions easily based on various situational scenarios. After experimenting on our system for 3 months, we found they had no aversion about wearing HMD and learned quicker as they practiced over and over and improved their cognitive capability and adaptive ability. We also got a positive feedback that it had an excellent educational value from teachers in special-education-school.

In this paper, It proposed the development of integrated data management's prototype system for aviation accident and incident system. With the recent development of the aviation accident investigation equipment, accident investigation system should collect and manage the various types of jpg, avi, and wav data files. However, the ECCAIRS system does not have a separate database for managing the various generated data during the accident investigation. And the Korea aviation accident management system also has the same problem. Therefore, in this paper, we analyze the aviation accident report system of major foreign countries and prepare a method to apply it to the domestic environment. Through the prototype of the integrated data management system, we confirmed the performance through inputting the existing data and the recently investigated data. We will use this result as basic data for completion of final integrated data management system.

Owing to the recent increased interest in wireless communication technology and rapid technology development, a range of applied technologies utilizing them are being released. In addition, at school, by adopting an attendance management system using wireless communication technology, attempts to solve problems caused by attendance books are being made. Representative attendance management systems include those using RFID, Bluetooth and clicker. Although these systems have solved the problem of wasting paper and time due to calling and writing attendance, they have other problems of generating additional expenses of purchasing or renting more equipment. To solve all of these problems, this paper suggests prototype system that can manage attendance by using NFC (Near Field Communication), which most smartphones provide. The attendance management system using NFC consists of two applications; one for professors and the other for students. The system solves problems, such as proxy attendance, loss of lesson time and additional cost by automatically managing attendance information using NFC and TCP/IP technologies.

In proteomics, recent advancements In mass spectrometry technology and in protein extraction and separation technology made high-throughput analysis possible. This leads to thousands to hundreds of thousands of MS/MS spectra per single LC-MS/MS experiment. Such a large amount of data creates significant computational challenges and therefore effective data analysis methods that make efficient use of computational resources and, at the same time, provide more peptide identifications are in great need. Here, SIFTER system is designed to avoid inefficient processing of shotgun proteomic data. SIFTER provides software tools that can improve throughput of mass spectrometry-based peptide identification by filtering out poor-quality tandem mass spectra and estimating a Peptide charge state prior to applying analysis algorithms. SIFTER tools characterize and assess spectral features and thus significantly reduce the computation time and false positive rates by localizing spectra that lead to wrong identification prior to full-blown analysis. SIFTER enables fast and in-depth interpretation of tandem mass spectra.

The national government is pushing hard the adoption of the BIM (Building Information Modeling) technology in the construction industry. The BIM application provides a visualized environment where the construction manager can inspect the structure of buidling structures. The application also provides information on activity progresses as well as earned values. However, BIM is mostly applied to visualize a structural object with definite forms. The BIM technology needs to be extended to include an object with non-definite forms such as earthwork operations. The objective of this study is to present a prototype of earthwork BIM in the construction operation. The prototype has been built on the attributes of geological information, construction equipment and positioning. The prototype of earthwork BIM shows a 3D graphic simulation of construction equipment moving around for digging and loading.

The Kyodong Island on the Yellow Sea has experienced dramatic transformations in the process of massive reclamations of tidal flats. Consisting originally of detached several islets, Kyodong became an integrated island country with the establishment of sea dikes across the salt marshes. The coastal plaines passed through four distinct stages of development. During the nascent period from the Early States to the Koryo Dynasty, strategic considerations led up to the establishment of causeways and garrison farms as well as private land plots. The relocation of regional headquarters of the navy into the island made the reclamation of tidal flats a systematic project during the period of Chosun Korea. The implantation of a large-scale estate by Japanese capitalists was the most characteristic feature of this region's geography during the colonial period. Present-day Kyodong displays various agrarian landscapes of standardized land plots, reinforced sea dikes, and automated agricultural machinery. Throughout the periods irrigation systems have sustained the panoramic transformation of the agricultural geographies of the Kyodong Island. The local people afflicted by a chronic deficiency of water came up with ingenuous irrigation systems such as springs, paddy reservoirs, reservoirs, tanks, artesian wells, and pump stations.

These days, with the advent of digital broadcasting, media environment offers users an opportunity to enjoy differentiated contents in a more aggressive fashion through user-media interactions based on computer technology. In fact, the development of contents which can induce spontaneous acts from users such as outdoor ads which use certain sensors and devices and exhibition halls has been active. With the development of low-price motion recognition devices, people have been able to enjoy diverse interaction-applied media by recognizing users' motion data without body contact. In this paper, we developed an interactive media player that can recognize the user's motion and control the video in the web service environment without installing a specific program. In addition, we set user motion recognition range and developed a user motion recognition algorithm suitable for the Leap Motion equipment installed in the kiosk. The results of this study can be experienced by various interactive media such as interactive tourism, education, and movie contents in kiosks that can be installed in public places.
