In order to meet increasing industrial demand for quality IT experts in the computer-software field, demand-driven undergraduate curriculums have been developed and applied to college education in Korea. The computer-software field has been categorized into several specialized areas, tracks, and educational contents have been designed and constructed for(More)
This research includes the study of the existing head-mounted display (HMD)enabled interface program and suggests improved interface scheme of HMD-enabled virtual reality (VR) games. The traditional keyboard and mouse based input schemes need to be replaced by user-friendly interface scheme such as the HMD. The higher the immersion degree of game users is(More)
This paper describes the prototype of the Massive Events Streams Service Architecture (MESSA), which is used as a framework of various RFID-enabled application systems. The MESSA captures events from a number of RFID readers, refines the events, processes the continuous queries, and delivers the event query results to the applications systems. In addition,(More)
This paper proposes the integrated design of an event stream service system architecture (ESSSA) which can be used as a gateway to capture and process enormous amounts of event streams continuously generated by radio frequency identification (RFID) or variable sensors over ubiquitous sensor network (USN) installed in a wide variety of locations, transfer(More)
With the proliferation of smart computing equipment, the range of providing highly intelligent services is widely expanding in an attempt to include the present condition of each individual data source. Furthermore, broadly adopted RFID (Radio Frequency Identification) technology has led to the widespread application of automatic identification in numerous(More)
The XCREAM (XLogic Collaborative RFID/USN-Enabled Adaptive Middleware), as a mediator between smart physical objects and collaborative cyber services, gathers massive events from a variety of event origins and distributes them to the appropriate service parties depending on the predefined business scenarios. Demand for collaboration among numerous(More)
With the rapid growth of network-enabled environment, the range of intelligent application services is widely expanding with continuous attempts to fully utilize highly accurate personal or environmental information. In parallel, a variety of professional knowledge data have been built up and provided to the public in the form of semantically linked(More)
This research first focused on processing enormous number of sensor events from a variety of city-wide sensor networks. As a solution, the well-known big data handling scheme, Hadoop cluster framework, drew, unquestionably, our attention.The acquired sensor events are to be used to immediately detect a certain abnormal situation within the framework.(More)
