  • This paper focused on the development of sports robot that detects a human player and shots a serve ball automatically. When robot technologies apply to the sports machine, the domain problems occurs such as outdoor environments and playing condition to recognize the visual and the vocal modalities. Gaussian mixture model and Kalman filter are used to detect the player's position in the left, right, and depth direction and to avoid the noises caused by the player's posture variation around the net. The sports robot is designed by the pan-tilt structure to shot a serve ball by pneumatic control under the multi layered software architecture. Finally, the proposed tracking and the machine performance are discussed by experimental results.

  • Through the past decades variable researches on Virtual Reality(VR) has been performed and acceptable by the computer and information technology development. VR has been used usefully also on construction industry It can visualize the construction process and simulates the construction operation considering environment and resources. However, VR has hardness to expressing the real world reality. Therefore, Mixed reality which is the blend of real world and virtual world is being emerged. Specially researches on Augmented Reality is actively performed. This study will focus on Augmented Reality technologies and research trend. Finally, the study will suggest schemes to apply Augmented Reality on Korean Construction Industry.

  • Over the past decade, the environment around libraries for the disabled has been greatly improved. Related legislation was established, facilities and facilities expanded, and the number of related collections and programs increased. In order to solve this problem, a survey of users' needs in accordance with the changing environment needs to be completed. In this study, we studied the existing research and analyzed the core needs of each type of disability employing user interviews and expert Delphi research. Users demanded quantitative and qualitative expansion of resources as well. Users needed personalized services and programs, convenience in using facility, accessibility of web and applications, and professional staff.

  • The most important and critical to the performance of video surveillance systems is to be detected exactly how much. In order to accurately track the object must be able to accurately separate the background and object. However, the system itself rather than the human vision exactly distinguish the object and the background, to assess the situation, it is not easy. If we can accurately detect the background and the object, to be able to accurately track an object, it is possible to increase the reliability of the system, have a significant impact on the success of the entire production system. In this paper, we propose a way to distinguish more precisely the background and the object being to determine the background environment changes more accurately.

  • A road is a fundammental public traffic facility for transporting people and goods. Road designer should determine the best route considering various conditions to minimize environmental bad effect due to road construction and show road functions sufficiently. In this research, we tried to select the optimal route location by comparing candidate routes considering weights of various items such as land use, slope, aspect, land price and so forth. The candidate routes were analyzed and visualized from built data using a GIS software and then compared with the existing route.

  • Recently, the necessity of new methods of spatial data integration and analysis in CRM has been increased since it is acknowledged that about eighty percent of all data stored in corporate databases has a spatial component. But conventional CRM systems are either incapable of managing spatial data or are not user-friendly when doing so. This paper has designed and implemented spatially-enabled integration management system that can manage consistently both enterprise and spatial data through a legacy CRM system and object-oriented database and additionally support spatial analysis and map visualization for a gCRM. Through implementation, it is demonstrated that the proposed system can facilitate effectively spatial data management and analysis in a legacy CRM system.

  • We have studied the problems associated with increasing number of ophthalmic optics students every year. The main problems are surplus supply of the optometrist and poor working condition. Thus all parties concerned who aim to solve the numerical unbalance of optometrist must have the common policy in sight. And we have to make a long-term plan and permanent organization for medical technician to establish supply and demand of medical technician with exact policy. To solve this unbalance of optometrist numbers, we have to establish an exact job category, reform the specialized education course, estimate the practical technique of national licensing examination for Korean optometrist, and innovate the contents and methods of reeducation.

  • Hospital managements are faced with severe competition and need more complicated information systems for its efficiency than before. Hospital managers have to deal with these environments and provide patients with better services than ever to survive. This thesis analyzes and redesigns the hospital administration processes in terms of patient-oriented view. For that purpose we define the processes of the hospital administration using process design tool like ARIS-Toolset. We also introduce basic concepts of Hospital Information Systems(HIS). We finally reviewed the result of reengineering of hospital management process with AHP methodology.

  • For the ubiquitous web environment internet, as an one of the R&D projects by Korean Land Spatialization Group, the project for platform technologies was initiated to provide customized land information and geospatial service. The platform technologies can be categorized for streaming, mashup and geosearch. More specifically, the 2D/3D hybrid streaming engine, mashup engine for u-GIS service and next generation search engine for land information have been developed. In this context, the patent analyses are required to propose the strategies for efficient development and use of these technologies. This study searches the related patents in Korea, US and EU, analyzes the trend of them for customized spatial information technologies, and finally proposes proper strategies.
