From the point of tectonic manner which is 'how to build a house' this study considers the characteristics of Kan in Hyangdan(香壇) at Yang-Dong Village. It was analysed with primary elements such as Kan, condition of a site, module, structural system, roofing system and their relationships in spatial and formal composition. Through the analysis, findings were achieved that characteristics of Kan to form a rectangle of 1 to root 2 proportion plan, enable irregularity in usage and regularity in compositional aspect and structural system to achieve intended roof design. In addition, Kan as a module is found to have a relative value that also regulates the whole in structural and aesthetical aspects.

Traffic analysis during past years used the Poisson distribution or Markov model, assuming an exponential distribution of packet queue arrival. Recent studies, however, have shown aperiodic and burst characteristics of network traffics. Such characteristics of data traffic enable the scalability of network, QoS, optimized design, when we analyze new traffic model having a self-similar characteristic. This paper analyzes the self-similar characteristics of a small-scale mixed traffic in a network simulation, the real network Traffic.

Considerations for user-centric environments are regarded as essential for the successful deployment of convergence services in BcN. Event driven service (EDS) is regarded as a typical convergence service converging different functions of multiple service providers to support user-centric environments. This paper first describes the deployment model and service scenario of EDS, a convergence service for user-centric environments in BcN. The user-centric environments stimulates the unified identifier management, namely unified identification (U-ID), to enable users to be provided convergence services without awareness of multiple providers. Then the designed structure and implementation results are given.

Chromosomal DNA fragments of Bacillus sp. YA-14 isolated from soil as a potent xylan hydrolyzing bacterium, were ligated to a vector plasmid, pBR322, and used to transfer Escherichia coli HB101 cells. The recombinant plasmid pYDC21 was found to enable the transformants to produce xylanase. pYDC21 was found to contain the 3 kb HindIII fragment originated from the Bacillus sp. YA-14 chromosomal DNA by southern hybridization. The optimum temperature and pH for the reaction of xylanse produced by E. coli (pYDC21) were appeared at 50$_7$C and pH 7.0, respectiveiy. the xylanase enzyme was stable between pH 5.0 and 7.0 and maintained stably up to 4$0^{\circ}C$.

As pervasive computing technology, which aims to get linked to useful knowledge, information or services anytime, anywhere, using any devices and/or artifacts, is proliferating, desirable impacts on knowledge management systems are now available. The pervasive computing technology will potentially enable the knowledge management systems to realize individualization and socialization and ultimately increase the knowledge processing productivity. However, researchers who apply the pervasive computing methodologies to novel way of knowledge management have been very few. These result in unsatisfactory consideration of establishing pervasive knowledge management systems. Hence, the purpose of this paper is to cast the vision of pervasive knowledge management and search for a couple of possible research issues and possibilities. This paper suggests a framework of ubiDSS, an amended knowledge management system for the next generation deploying pervasive and autonomous knowledge acquisition capabilities of ubiquitous computing technologies. Also the CKAM, context-based knowledge acquisition module, is illustrated as a prototype of future knowledge management systems.

This paper introduces a study for procedurally generating the behavior of objects in a virtual environment at runtime. This study was initiated to enable the behavioral model of objects in virtual reality applications to evolve in response to user behavior at runtime. Our approach is to describe the behavior of an object as a behavior tree, and to make a node of the behavior tree change to another type if a certain condition is satisfied. We defined four types of node changes: "parameterized", "probabilistic", "alternate", and "variant". We experimented with a virtual environment that includes a variety of simple procedural elements to explore the possibilities of our approach. As a result of the implementation, if an optimization algorithm that can select and apply the optimized procedural elements in response to the user's behavior is complemented, it is confirmed that more intelligent objects and agents can be implemented in virtual reality applications.

In this paper, we propose a vision-based object detection and tracking system using online learning. The proposed system adopts a feature point-based method for tracking a series of inter-frame movement of a newly detected object, to estimate rapidly and toughness. At the same time, it trains the detector for the object being tracked online. Temporarily using the result of the failure detector to the object, it initializes the tracker back tracks to enable the robust tracking. In particular, it reduced the processing time by improving the method of updating the appearance models of the objects to increase the tracking performance of the system. Using a data set obtained in a variety of settings, we evaluate the performance of the proposed system in terms of processing time.

Spontaneous spinal subdural hematoma is reported at a rare level of incidence, and is frequently associated with underlying coagulopathy or those receiving anticoagulant or antiplatelet agents; some cases accompany concomitant intracranial hemorrhage. The spontaneous development of spinal subdural hemorrhage (SDH) is a neurological emergency; therefore, early diagnosis, the discontinuation of anticoagulant, and urgent surgical decompression are required to enable neurological recovery. In this report, we present a simultaneous spinal subdural hematoma and cranial subarachnoid hemorrhage, which mimicked an aneurysmal origin in a female patient who had been taking warfarin due to aortic valve replacement surgery.

We focus on the network itself and its ability to enable efficient and effective information flow. All networks are complex to a greater degree, including military command and control systems operating in a network-centric environment. It requires to understand the nature of complexity, what its effects are, and how to quantify them. In this paper, we present the beneficial effects of information accessibility and network-based redundancy into a single metric.

Keyboard is a link between human and terminal, so we can input knowledge to information device. The misstyping is occured or the speed is reduced if there would be transmission error. We always have to consider human interface and behavior effect, because the keyboard system is the harmony of human and machine. This paper is designed for representation of ortho-phonics alpabetic one hand strock keyboard which is enable to correct error and to edit word.
