This paper proposes Visual Script Language which can direct a type of motion to 3D human model and create by dragging gesture like as we can express a certain meaning with hand gestures. Traditional motion control technique of articulated figures such as human needs a complex task that draws on highly developed human skills. So it will reduce the amount of motion specification to provide the motion control method that allow users to describe characters' motion at the higher level abstraction. Visual script is the visual gestures to direct various human motions, so users can express the spatial attributes of a motion such as the path of moving with high-level concepts if they use visual script. And we can show that it is possible to control the motion of human model directly and intuitively by development of 3D human motion control system based on visual script.

This paper aims to provide a conceptual framework to see the special zones in East Asia in relation to the territorialities of the state. For this, it will introduce Aihwa Ong's notion of 'spaces of exception', and provide some critical discussions on it. Unlike Ong, I do not see the spaces of exception as an outcome of neoliberal changes of the state. Instead, I propose to see the special zones in terms of the internal limitations of the modern state territoriality. In particular, I try to theorize the special zones in relation to the dialectics of the contradictory relations between mobility and fixity inherent in the territoriality of the modern nation state. In addition, it will be suggested to see special zones as an essential part of the spatiality of the East Asian developmental states, given the spatio-temporal contexts of the East Asian capitalist development. On the basis of these theoretical discussions, this paper will divide the special zones that have been developed in East Asia since the 1960s into 3 different types, including 1) developmentalist special zones, 2) neo-liberal special zones, and 3) special zones for transition, and discuss their characteristics.

최근 소셜 네트워크 서비스는 언제 어디서나 정보를 누구라도 손쉽게 전달하고 볼 수 있는 수단으로 각광받고 있다. 소셜 네트워크 서비스의 주요한 특징은 사람과 사람, 사람과 정보, 정보와 정보 간의 관계 네트워크로서, 사용자가 능동적으로 참여한다는 것이다. 하지만 범람하는 수많은 정보들 속에서 사용자가 직접 정보를 검색 및 분류해야 하는 과정은 사람과 정보간의 관계 네트워크 측면에서 소셜의 의미를 충족하지 못한다. 이러한 기존의 정보 활용법은 사용자의 선호도에 따른 맞춤형 정보의 수용과 공유를 제시하지 못하고 있다. 본 연구에서 설계된 사용자 맞춤형 서비스 시스템은 사용자의 상황인식 속성정보와 이에 따른 선호도를 평가하는 알고리즘을 기반으로 하여 보다 효율적인 커뮤니티 공간이 제공될 수 있는 맞춤형 커뮤니티 서비스 시스템을 설계 제안한다. 제안된 시스템에서는 소셜 네트워크 서비스에서 사용자가 텍스트를 읽거나 작성하는 행위를 바탕으로 사용자의 관심사를 제공된 알고리즘으로 분석하여 사용자의 선호도에 따른 정보를 분류하고, 사용자의 인적정보로부터 선별한 유사 사용자들을 통해 신뢰성이 높은 정보를 우선적으로 선출한다. 따라서 사용자의 속성과 선호도를 고려한 상황인식 정보를 제공함으로써 사용자가 직접 정보를 검색 및 분류하는 과정을 단축하고 정보의 신뢰성을 향상할 수 있는 방법을 제시한다. 이러한 상황인식 기반의 맞춤형 커뮤니티 서비스 시스템은 실시간으로 많은 정보가 공유되는 서비스에서 다양하게 적용되어 인터넷 신문, 타겟 마케팅 광고 등의 응용분야에서 다양한 정보제공 서비스 시스템으로 적용될 수 있을 것으로 본다.

In this paper, the spatiotemporal data mining methodology for detecting a cycle of power consumption pattern with the change of time and spatial was proposed, and applied to the power consumption data collected by GIS-AMR system with an aim to use its resulting knowledge in real world applications. First, partial clustering method was applied for cluster analysis concerned with the aim of customer's power consumption. Second, the patterns of customer's power consumption data which contain time and spatial attribute were detected by 3D cube mining method. Third, using the calendar pattern mining method for detection of cyclic patterns in the various time domains, the meanings and relationships of time attribute which is previously detected patterns were analyzed and predicted. For the evaluation of the proposed spatiotemporal data mining, we analyzed and predicted the power consumption patterns included the cycle of time and spatial feature from total 266,426 data of 3,256 customers with high power consumption from Jan. 2007 to Apr. 2007 supported by the GIS-AMR system in KEPRI. As a result of applying the proposed analysis methodology, cyclic patterns of each representative profiles of a group is identified on time and location.

순차 패턴 탐사 기법은 순서를 갖는 패턴들의 집합 중에 빈발하게 발생하는 패턴을 찾아내는 기법이다. USN 환경에서 발생하는 스트림 데이터는 시간 속성을 갖는 이벤트들의 집합으로 표현할 수 있으며 순차 패턴 탐사 기법을 이용하여 유용한 정보를 탐사할 수 있다. 그러나 스트림 데이터 환경에서는 데이터가 무한하고 연속적으로 발생하기 때문에 모든 데이터를 저장하여 패턴을 탐사하는 기법을 적용하는 데는 문제가 있다. 이 논문에서는 향상된 데이터 처리방식을 사용하여 순차패턴을 탐사하는 스트림 데이터 마이닝 기법에 대하여 제안한다. 제안하는 기법은 의미 단위의 가변적 윈도우를 사용하여 스트림 데이터로부터 트랜잭션을 생성하고 이 트랜잭션들의 집합을 해시와 슬라이딩 윈도우를 사용하여 스트림 데이터의 순차 패턴을 탐사한다. 이를 이용한 제안 기법은 실시간 시스템에 적합하게 데이터 저장 공간 사용의 효율성을 높이고 신속하게 유용한 패턴을 탐사할 수 있다.

One of the most important functions digital libraries need to offer is to help users find necessary information in a distributed environment in the most efficient and effective manner. In order to meet the goal, it is desirable to link scattered pieces of information and present them as a logically coherent whole when the user wants it, so that he or she doesn't need to know their physical location. The virtual document is an integrated document that the total or part of the physical documents stored in a specific repository are linked dynamically. Our MIRAGE-III digital library system provides a content-based retrieval of physical documents and the virtual documents in XML. This system provides a retrieval of partial documents, attributes and hierarchical structures and linked-documents based in structured documents like XML or SGML. In this paper we describe a methodology of design and implementation of the query processor and retrieval server in the MIRAGE-III digital library system.

This study is about the French preposition de. This preposition is considered to have no meaning in the French language, and to have only the grammatical function in its use. This study begins with doubts about such views regarding this preposition. We organize and classify general descriptions of the uses of this preposition. The uses are classified as 'expressing starting point,' 'giving characteristics' and 'performing grammatical functions' and this data is analyzed in terms of the associated cognitive grammar. In the case of expressing the starting point, it is assumed that the trajector moves from the starting point, to the destination point, in the domain of space and in the domain of time. Therefore, it is noted in this case that the preposition de has a dynamic concept. On the other hand, it is significant to understand that the preposition of the 'giving characteristics' defines an outline of a particular class by giving the class's characteristics. The preposition de has a static concept in this case. For the preposition de which introduces the infinitive, all of these dynamic and static concepts are faded and extremely grammaticalized.

Science Revolution, which stands for new paradigm in an era as a transfer, usually is accompanied with a change in intellectual sphere. Futhermore, as there is an indissoluble connection between science and an, so the correlation of two realm lead to mutual prosperity in coexistence. Recently, concerns for the phenomena of non-linear dynamics in science and its quick adaptation in art made .it possible. What is important agenda for science and art is to suggest the process of creative evolution and its method, I believe. In order to attain these, different and contra way of thinking, spirit of research and venture for unpredictable things out of daily routine should be indispensible. In this study, I am offering and reviewing the space design based upon phenomena of nonlinear dynamics, drawn from concept of chaos in physics and mathematics. This study places a great emphasis on nonlinearity which should be understood as a whole, not partially, that enable a designer to find new cosmos and principles of creation. In addition to these, I wish that a designer would stop trying partial apply in nonlinear space. In fine, I hope this study enables a designer to adapt and generate nonlinearity as creative attribute in space by understanding of phenomena of nonlinear dynamics and its process as a whole.

This study is an architectural design thesis aimed at designing a building at the River Thames in London, which could float along the river and be anchored in the river, in terms of the concept of the sense of place. The process of the study was as follows. First, theoretical backgrounds of the concepts of sense of place, placelessness, and non-place were examined and the sense of place of River Thames was analyzed. Second, the architectural planning elements could be applied to architectural design in terms of the relationship between the place and architecture, form of architecture, and behaviors of peoples. Third, the architectural design concepts and programs were specified based on the planning elements and a cultural complex that floats on the River Thames in London, England was proposed. The focus of this study was the process of formation of a sense of place by the cognition of architecture and people's activity, and this study claimed that the sense of place could be materialized by the metaphorically inherent property of the architecture.

분류 기법은 데이터 마이닝 기술 중 가장 잘 알려진 방법으로서, Decision tree, SVM(Support Vector Machine), ANN(Artificial Neural Network) 등 기법을 포함한다. 분류 기법은 이미 알려진 상호 배반적인 몇 개 그룹에 속하는 다변량 관측치로부터 각각의 그룹이 어떤 특징을 가지고 있는지 분류 모델을 만들고, 소속 그룹이 알려지지 않은 새로운 관측치가 어떤 그룹에 분류될 것인가를 결정하는 분석 방법이다. 분류기법을 수행할 때에 기본적으로 특징 공간이 잘 표현되어 있다고 가정한다. 그러나 실제 응용에서는 단일 특징으로 구성된 특징공간이 분명하지 않기 때문에 분류를 잘 수행하지 못하는 문제점이 있다. 본 논문에서는 이 문제에 대한 해결방안으로써 많은 정보를 포함하면서 빈발패턴에 대한 정보의 순실이 없는 닫힌 빈발패턴 기반 분류에 대한 연구를 진행하였다. 본 실험에서는 ${\chi}^2$(Chi-square)과 정보이득(Information Gain) 속성 선택 척도를 사용하여 의미있는 특징 선택을 수행하였다. 그 결과, 이 연구에서 제시한 척도를 사용하여 특징 선택을 수행한 경우, C4.5, SVM 과 같은 분류기법보다 더 향상된 분류 성능을 보였다.
