    Manish Pokharel , 최승준 , 이봉재 and 1 other persons | 2011, 6(1) | pp.1~16 | number of Cited : 0
    Abstract PDF
    The main objective of Enterprise Architecture (EA) is to coordinate among the components of the architecture and to bridge the gap between the changes in business process and advancement of technology. Despite its use, popularity and continuing researches, there are still shortcomings in exiting EA in the areas such as addressing legacy system, reliability, affordability, maintainability, and interoperability. Adaptation in line with changes in business process and technology is still considered a critical challenge. In this paper, we address such critical challenges with use of Service Oriented Architecture (SOA), Product Line Architecture (PLA), Expert System (ES) and also Cloud Computing. The proposed architecture provides the features such as adaptability, reusability, maintainability and scalability.

    Empirical Analysis of a Large-Scale Blog Workload

    전명제 , Byoung-Chan Jeon , 이영규 | 2011, 6(1) | pp.17~26 | number of Cited : 1
    Abstract PDF
    This paper presents a detailed characterization study of Web 2.0 workload through an analysis of real-world Web access logs collected from Tistory, one of the largest blog hosting services in South Korea. Compared to traditional Web workloads, Tistory’s workload shows different characteristics; the content creation from a number of end users drastically changes user participation characteristics, file type properties, and static and dynamic content behavior. Therefore, we delve deeply into the user-created content by following two-tier hierarchical approach that analyzes the Tistory’s workload into the file and article level. Through this paper, the observed characteristics are approximated by theoretical distributions to provide data for generating synthetic workloads.

    Analysis on the Image Characteristics and Attractiveness of City in Knowledge-information Society -The Case Sunchon city-

    이정 | 2011, 6(1) | pp.27~35 | number of Cited : 0
    Abstract PDF
    In current Knowledge-information Society, advanced information technology and the development of transport systems have changed psychological and physical characteristics in a city, as well as the city lifestyle. As a result, the citizens require the new city's image and environment to cope with their changed lifestyle. In this study, cognitive characteristics on the landscape, a city's images and attractions have been analyzed. The results of this study could have a potential role as a planning and design criteria which are suitable for the Knowledge-information society. The research data was collected in Sunchon-city and main results of this study are as follows:While the positive attitudes for the image of city were 'intimate(3.45)', 'traditional(3.36)' and 'amenity(3.30)', the negative attitudes were 'flat(2.63)', 'scattering(2.69)', 'un-new(2.69)',and 'monotonous(2.74)'. Total satisfactory level of the city image was estimated to be 6.18. The psychological factors related to the satisfaction of the city image were composed of five characters such as 'individuality', 'potentiality', 'pleasure', 'amenity' and 'naturalness'. The estimation formula for the satisfaction was: Satisfaction = 6.202 + 0.464(Potentiality) + 0.446(Individuality) + 0.367(Pleasure) + 0.322(Amenity) + 0.245(Naturalness) While the positive attitudes for the city attraction were 'possible of development(3.99)', 'cleanness(3.69)' and 'many heritages(3.53)', the negative attitudes were 'a few industrial facilities(2.35)' 'a few entertainments(2.42)' and 'a few cultural events(2.55)'. The total score for attraction was estimated to be 6.39.

    Sang-Wook Kim | 2011, 6(1) | pp.37~43 | number of Cited : 2
    Abstract PDF
    This paper uses LQ(Location Quotient), and estimates the regional specialization of IT manufacturing in China, and compared with regional differences. IT manufacturing is the leading industry in China, but there are exist the regional disparity and regional concentration difference. Most of IT manufacturing production base located in the Eastern region in China, and the Middle and Western region have the low development level of IT manufacturing. In the manufacture of electronic equipment and communication equipment, the LQ of Guangdong, Jiangsu, Shanghai, Tianjin have the higher regional specialization relatively, and the another region have the lower regional specialization relatively. In the manufacture of computers and office equipment, the LQ of Guangdong, Jiangsu, Shanghai have the higher regional specialization relatively, and the another region have the lower regional specialization relatively. The result indicates that Tianjin has no regional specialization in the manufacture of computers and office equipment, compared with another regions relatively.

    Abstract PDF
    Many games are developed by use various toolkit. This paper proposes a development of battle city, which is a famous classic arcade game. An arcade game is a coin-operated entertainment machine, usually installed in public businesses such as public houses, and video arcades. Most arcade games are redemption games, merchandisers (such as claw crane), video games, or pinball machines. However, the objective of this paper is to produce a tank game using directX library instead of the specialized engines. The advantage is that the overall cost of the production would be minimized since there is no need to invest in making game engine. Users can enjoy to easily the proposed game.

    Improving On-line Handwritten Character Recognition with Hidden Markov Model

    마명 , Park Dong-Won | 2011, 6(1) | pp.61~68 | number of Cited : 0
    Abstract PDF
    Method for on-line handwritten character recognition with Hidden Markov Model(HMM) is proposed. To deal with the problem of handwriting style variations, the Hierarchical Clustering approach is introduced to partition different writing styles into several classes. One HMM that models temporal and spatial variability of handwriting is constructed based on each class. Therefore a multiple modeling technique is used for both Korean and English characters. The HMMs of Korean graphemes are concatenated to form the Korean character models. The recognition of handwriting characters is implemented by a modified level building algorithm, which incorporates the Korean character combination rules within the efficient network search procedure. Due to the limitation of HMM based method, a post-processing procedure which takes the global and structural features into account is proposed. Experiments showed the proposed recognition system which uses multiple modeling technique, the modified level building algorithm and the post-processing procedure achieved high writer independent recognition rate on unconstrained samples of both English and Korean characters. The comparison with other schemes of HMM-based recognition is also performed to evaluate the system.

    노성남 , SUN-JEONG KIM , Song Chang Geun | 2011, 6(1) | pp.131~140 | number of Cited : 0
    Abstract PDF
    In this paper, we propose a realtime terrain synthesis algorithm to generate realistic terrain using DEM(Digital Elevation Model) data. Through analysis of the given DEM data, we extract samples which has the information about directions of terrain patches. Users input guidelines with virtual canvas and then we compose the sample data as following directions of guidelines to build a realistic terrain. In order to remove cracks between terrain patches, we use filtering and height normalization. Users can generate a new terrain interactively because we apply GPU(Graphics Processing Unit) rendering technique. Using the proposed algorithm we synthesized realistic terrains based on user-input various types of guidelines.

    Abstract PDF
    In this paper, we implement a real-time surveillance monitoring and object tracking system using PTZ(Pan-Tilt-Zoom) camera. For object tracking, we use the mean shift tracking algorithm and a modified kernel function based on color image distribution of detected object. Mean shift algorithm is suitable for real-time tracking because of fast and stable performance. In the proposed system, MatLab is used for accessing the PTZ protocol and RS-485 communication for controlling the position of PTZ camera in order to arrange the object in the middle part of the monitor screen in the real-time. This system can be used in an effective and fast image surveillance system for continuous object tracking in a wider area.
