    노창현 , 조규철 , 마용범 and 1 other persons | 2008, 13(1) | pp.1~10 | number of Cited : 4
    Abstract PDF
    In order to high-performance data processing, effective resource selection is needed since grid resources are composed of heterogeneous networks and OS systems in the grid environment. In this paper, we classify grid resources with data properties and user requirements for resource selection using a decision tree method. Our resource selection method can provide suitable resource selection methodology using classification with a decision tree to grid users. This paper evaluates our grid system performance with throughput, utilization, job loss, and average of turn-around time and shows experiment results of our resource selection model in comparison with those of existing resource selection models such as Condor-G and Nimrod-G. These experiment results showed that our resource selection model provides a vision of efficient grid resource selection methodology.

    A Voronoi Diagram-Based Grid Structure for Efficient Nearest Neighbor Query Processing

    권동섭 | 2008, 13(1) | pp.11~20 | number of Cited : 2
    Abstract PDF
    Nearest-neighbor searches are essential operations in various applications such as multimedia systems and GIS systems. Although numbers of research works for nearest-neighbor search have been proposed, they have a limitation on the performance since they process queries on the fly with indexes on data. This paper proposes a new nearest-neighbor search algorithm based on a grid-based data structure, which preprocesses and stores the result of nearest-neighbor queries using Voronoi diagrams over static data. While traditional techniques try to index data itself, the proposed technique attempts to index the result of the queries. Therefore, it performs nearest-neighbor queries more efficiently.

    A Dynamic Co-scheduling Scheme for MPI-based Parallel Programs on Linux Clusters

    김혁 , Yunseok Rhee | 2008, 13(1) | pp.29~36 | number of Cited : 0
    Abstract PDF
    For efficient message passing of parallel programs, it is required to schedule the involved two processes at the same time which are executed on different nodes, that is called 'co-scheduling'. However, each node of cluster systems is built on top of general purpose multitasking OS, which autonomously manages local processes. Thus it is not so easy to co-schedule two (or more) processes in such computing environment. Our work proposes a co-scheduling scheme for MPI-based parallel programs which exploits message exchange information between two parties. We implement the scheme on Linux cluster which requires slight kernel hacking and MPI library modification. The experiment with NPB parallel suite shows that our scheme results in 33-56% reduction in the execution time compared to the typical scheduling case, and especially better performance in more communication-bound applications.

    김재우 , Jaewon Song , Ju-Hong Lee | 2008, 13(1) | pp.37~44 | number of Cited : 1
    Abstract PDF
    Data stream has the tendency to change in patterns over time. Also known as concept drift, such problem can reduce the predictive performance of a classification model. CVFDT and IOLIN tried to solve the problem of a concept drift through incremental classification model updates. The local changes in patterns, however, was revealed to be unable to resolve the problems of local concept drift that occurs by influencing on total classification results. In this paper, we propose adapted IOLIN system that improves system's predictive performance by detecting the local concept drift. The experimental result shows that adaptive IOLIN, the proposed method, is about 2.8% in accuracy better than IOLIN and about 11.2% in accuracy better than CVFDT.

    Fuzzy Based Selection Technique for Character Action in Game Balancing

    현혜정 , Kim Taesik | 2008, 13(1) | pp.81~88 | number of Cited : 2
    Abstract PDF
    In the game balancing, it is so difficult to choose suitable arms among various actions, or arms and to accurately calculate to which level we adjust the balance. The fuzzy method can be properly used in a particular environment which cannot be correctly processed in mathematics or in lessening the time-consuming problems during the accurate number crunching. Because a variety of actions, relations with opponents, previous battle experiences etc. are not easy to be reflected in every occasion, the fuzzy method could be useful in these cases. When the balancing is needed, the data which have been played to that point are processed by the fuzzy function and calculated to adapt intensity to each action. The ability of characters is regulated in this process. To demonstrate the efficiency of this method, I would like to make clear the excellence of fuzzy method through the following five experiments; a case with invariable ability adjustment, a case adjusted by a randomly chosen action, a case with the strongest weapon selection, a case with the weakest weapon selection and a case with the fuzzy method application.

    Kang Sun-Kyung , 김영운 , 소인미 and 1 other persons | 2008, 13(1) | pp.89~98 | number of Cited : 5
    Abstract PDF
    In this paper, we present a method for the enhancement of marker detection correctness and marker recognition speed by using artificial neural network. Contours of objects are extracted from the input image. They are approximated to a list of line segments. Quadrangles are found with the geometrical features of the approximated line segments. They are normalized into exact squares by using the warping technique and scale transformation. Feature vectors are extracted from the square image by using principal component analysis. Artificial neural network is used to checks if the square image is a marker image or a non-marker image. After that, the type of marker is recognized by using an artificial neural network. Experimental results show that the proposed method enhances the correctness of the marker detection and recognition.

    Parallel Rendering of High Quality Animation based on a Dynamic Workload Allocation Scheme

    Yunseok Rhee | 2008, 13(1) | pp.109~116 | number of Cited : 0
    Abstract PDF
    Even though many studies on parallel rendering based on PC clusters have been done, most of those did not cope with non-uniform scenes, where locations of 3D models are biased. In this work, we have built a PC cluster system with POV-Ray, a free rendering software on the public domain, and developed an adaptive load balancing scheme to optimize the parallel efficiency. Especially, we noticed that a frame of 3D animation are closely coherent with adjacent frames, and thus we could estimate distribution of computation amount, based on the computation time of previous frame. The experimental results with 2 real animation data show that the proposed scheme reduces by 40% of execution time compared to the simple static partitioning scheme.

    Content-based Image Retrieval Using Color and Shape

    하정요 , 최미영 , HYUNG IL CHOI | 2008, 13(1) | pp.117~124 | number of Cited : 10
    Abstract PDF
    We suggest CBIR(Content Based Image Retrieval) method using color and shape information. Using just one feature information may cause inaccuracy compared with using more than two feature information. Therefore many image retrieval system use many feature informations like color, shape and other features. We use two feature, HSI color information especially Hue value and CSS(Curvature Scale Space) as shape information. We search candidate image form DB which include feature information of many images. When we use two features, we could approach better result.

    An Improved Method for the Identification of the Space-Vriant Motion Blur using RATS

    양홍택 , 황주연 , Paik Doowon | 2008, 13(1) | pp.125~134 | number of Cited : 0
    Abstract PDF
    Motion blur is a blurring effect on an image caused by the relative motion between the camera and objects in the scene. When an image is captured, motion blurs are caused by relative motion between the camera and the scene. When different objects are moving at different speeds, the characteristics of the blur effect for each object appear differently. To restore the spatially variant blurred image, each of the blur extents should be identified. In this paper, we propose a new method for the identification of blur extent locally using RATS from the image in which the spatially variant motion blur is caused Experiment shows that the proposed algorithm successfully segments the objects with different blurs and identifies the blur extents quite well.

    BER performance of MIMO 16QAM with transmit and receive polarization diversity technique on mobile communication channel

    김태헌 | 2008, 13(1) | pp.135~142 | number of Cited : 0
    Abstract PDF
    The utilization techniques for multiple transmit and receive antennas or high capacity modulation schemes are essential to cope with the rapidly increasing demand for realizing more diverse wireless communication services with high rates. However, employing multiple receive antennas at the mobile units seems less practical due to the size and power limitations. Therefore, transmit diversity techniques have been extensively investigated for the downlink transmission to improve the performance. In order to overcome the above mentioned problems, we construct a simulation model which combines STC and polarization diversity which scheme is requiring less cost to realize. Multi-level quadrature amplitude modulation (MQAM) is an attractive modulation scheme for wireless communication due to the high spectral efficiency it provides. Thus, the performance for our scheme is presented when 16QAM modulation techniques are applied, and compared with the former schemes.

    Problems of certificate status validation methods using hash chain and their countermeasure

    Hyun-Joong Kang , 안정희 | 2008, 13(1) | pp.161~168 | number of Cited : 0
    Abstract PDF
    As the authentication and the integrity methods based on the hash chain are popular, several certificate status validation methods based on the same function are proposed at the moment. In NOVOMODO, a CA generates and releases the hash value to each user. In Jianying Zhou’s framework and Jong-Phil Yang’s framework, a user generates and releases the hash value to verifier. Therefore, the CA loads are distributed to each user. However, these frameworks are based on the assumption that the CA’s secret key is not lost or compromised and the certificates issued by the CA are error-free. Therefore, these frameworks are not suitable in real PKI environments. In this paper, as one hash value generated by CA is included in the user’s certificate in addition, the certificate revocation published by CA using that value can be managed. The hash value included in user’s certificate is the same for all users. The computation costs, the storage amounts and the release costs are small in the CA. And we modify the procedure for the signature and its validation in Jong-Phil Yang’s framework. Our solution is more suitable than those frameworks in real PKI environments.

    Paik Doowon , 임헌규 , 황주연 | 2008, 13(1) | pp.169~174 | number of Cited : 0
    Abstract PDF
    A navigation system for virtual environments using low-quality HMD(head mounted display) must quantize images when the system presents true-color image with restricted number of colors. Such navigation system quantizes an image by using fixed palette. If the system represents an image by using a variable palette which is made considering a region around the viewpoint then user can perceive a virtual environments more vividly because human visual system is sensitive to the colors variation in the region around the viewpoint. In this paper we propose a color quantization algorithm that quantize a region around the viewpoint more finely than other regions at each variation of viewpoint for virtual environments navigation system.

    One-Way Delay Estimation Using One-Way Delay Variation and Round-Trip Time

    김동근 , Lee Jaiyong | 2008, 13(1) | pp.175~184 | number of Cited : 0
    Abstract PDF
    QoS-support technology in networks is based on measuring QoS metrics which reflect a magnitude of stability and performance. The one-way delay measurement of the QoS metrics especially requires a guarantee of clock synchronization between end-to-end hosts. However, the hosts in networks have a relative or absolute difference in clock time by reason of clock offsets, clock skews and clock adjustments. In this paper, we present a theorem, methods and simulation results of one-way delay and clock offset estimations between end-to-end hosts. The proposed theorem is a relationship between one-way delay, one-way delay variation and round-trip time. And we show that the estimation error is mathematically smaller than a quarter of round-trip time.

    The Method of New Robust Inverse Filter Design in 2-Ch Audio System

    박병욱 , Kim, Hack-Yoon | 2008, 13(1) | pp.185~192 | number of Cited : 0
    Abstract PDF
    The crosstalk is the most serious problem in playing audio signals with more than two speakers. Usually an inverse filter is employed to remove such a phenomenon. The LNS method, one of most effective design techniques for an inverse filter, has some advantages such as easy implementation and quick computation. However, the inverse filter designed by the LNS method is not easy to adapt immediately for the delivery system change since the pre-measured impulse response is used to design the filter. In this work, we present an adaptive algorithm for the inverse filter design. With the present algorithm, the inverse filter is initially designed by the LNS methods and continuously adjusted to cope with the delivery system changes. To verify the proposed method, some simulations were carried out and the results confirmed that the performance of the crosstalk calculation can be improved in entire frequency range.

    리현희 , 김정아 , 명세화 and 1 other persons | 2008, 13(1) | pp.193~202 | number of Cited : 0
    Abstract PDF
    In this study, we want to composite the source image and the target image when the environment includes water surface in the target image such as lake, sea, etc. The water surface is different from other common environment. On the water surface, the object must be reflected or refract and sometimes is deformed by the wave of water. In order to composite the object in the source image onto the water image, we analyze the water surface of the target image and let the object be synthesized realistically based on the wave of water. Our composite process consists of three steps. First, we use Shape-from-Shading technique to extract the normal vector of the water surface in the target image. Next, the source image is deformed according to the normal vector map. Finally, we composite the deformed object onto the target image.

    Document Replacement Policy by Web Site Popularity

    유행석 , 장태무 | 2008, 13(1) | pp.227~232 | number of Cited : 0
    Abstract PDF
    General web caches save documents temporarily into themselves on the basis of those documents. And when a corresponding document exists within the cache on user's request, web cache sends the document to corresponding user. On the contrary, when there is not any document within the cache, web cache requests a new document to the related server to copy the document into the cache and then turn it back to user. Here, web cache uses a replacement policy to change existing document into a new one due to exceeded capacity of cache. Typical replacement policy includes document-based LRU or LFU technique and other various replacement policies are used to replace the documents within cache effectively. However, these replacement policies function only with regard to the time and frequency of document request, not considering the popularity of each web site. Based on replacement policies with regard to documents on frequent requests and the popularity of each web site, this paper aims to present the document replacement policies with regard to the popularity of each web site, which are suitable for latest network environments to enhance the hit-ratio of cache and efficiently manage the contents of cache by effectively replacing documents on intermittent requests by new ones.

    The System Implementation for a Learning Effect Improvement using an E-catalog

    함호종 | 2008, 13(1) | pp.233~242 | number of Cited : 0
    Abstract PDF
    In order to increase the learning effect in minimal time, it is required that the lecturer tailor the materials to suit the needs and achievement levels of each individual. However, in lecture environments such as in junior colleges, many students enroll under one professor, and many courses are open under the same course title at each department, where each enrolled student possesses different academic needs and achievement levels. Therefore, this paper proposes a learning system based on a hypothesis that if a lecturer shares his/her course material to students in other classes of the same subject, and opens up other professors’ grading and marks of the same subject to his students, their achievement levels will improve by utilizing other peers’ achievements and needs. Also, in order to improve the learning performance, we utilized an e-catalog in order to access students’ grading, corrections and coaching, ultimately saving time and cost.

    Research on Success Factors of Enterprise Architecture(ITA/EA) through Policy Standardization

    이준열 , Byeong-Soo Jeong | 2008, 13(1) | pp.273~281 | number of Cited : 1
    Abstract PDF
    In a knowledge-information based society, effective management across IT industries, value of information and interoperation are more important than ever before. Therefore, ITA/EA which helps to plan and manage IT systematically and effectively, was enacted and announced in 2005 and has been considered as an innovative IT management approach. Unfortunately, however, new standardization of ITA/EA has not fully discussed yet. How to successfully apply EA/ITA to IT is considered as the most urgent challenge and this study aims to find out the most effective method. To this end, it was emphasized that training systems for specialized experts must be operated systematically through 'standardization of terms and tasks' and 'standardization of manpower training' and certification of specialty must be newly established. In addition, it was strongly demanded that dual structure caused by mixed concepts between ITA and EA must be eliminated. At the same time, a new model for domestic standardization was suggested so that not only ITA/EA can be recognized as IT engineering but also professional engineers can accept ITA/EA as a scientific field. In summary, this study is intended to propose how to improve information management efficiency through ITA/EA.
