This paper presents the Lexical Ambiguity Resolution System of Korean Language. This system uses Dependency grammar and Collative Semantics. Dependency grammar is used to analyze Korean syntactic dependency. A robust way to analyze a sentence is to establish links between individual words. Collative Semantics investigates the interplay between lexical ambiguity and semantics relations. Collative Semantics consists of sense-frame, semantic vector, collation, and screening. Our system was implemented by C programming language. This system analyzes sentences, discriminates the kinds of semantic relation between pairs of words senses in those sentences, and resolves lexical ambiguity.

In this paper, design and implementation of RIA(: Rich Internet Application) technology, a CMS based on either of the Adobe Flex framework. Flex existing HTML + CSS + Javascript, etc. it can be easily added to a variety of visual components on a markup language consisting allow you to implement a more dynamic website. The HTTP request is processed using the Spring Framework of MVC based. Spring Framework provides a number of services for the development of a dynamic website to open source framework for the Java platform. It is being used as a standard-based technology for e-government framework used to develop recommendations and Republic of Korea during the Web service public institutions. Extensive production becomes increasingly thin web can be more efficiently managed, and will provide convenience to the user.

This paper presents an efficient hardware architecture to improve the frame memory interface occupying the largest hardware area together with motion estimator in implementing MPEG-2 video encoder as an ASIC chip. In this architecture, the memory size for internal data buffering and hardware area for frame memory interface control logic are reduced through the efficient memory map organization of the external SDRAM having dual bank and memory access timing optimization between the video encoder and external SDRAM. In this design, 0.5 m, CMOS, TLM (Triple Layer Metal) standard cells are used as design libraries and VHDL simulator and logic synthesis tools are used for hardware design add verification. The hardware emulator modeled by C-language is exploited for various test vector generation and functional verification. The architecture of the improved frame memory interface occupies about 58% less hardware area than the existing architecture[2-3], and it results in the total hardware area reduction up to 24.3%. Thus, the (act that the frame memory interface influences on the whole area of the video encoder severely is presented as a result.

Importance of coordination among heterogeneous devices is significantly increasing to meet the challenges presented by the evolvement of the ubiquitous computing environment. The web services technology is going up as a promising solution to support the inter-operability between such heterogeneous devices via well-defined protocol. Currently, ECA(Event-Condition-Action) rule based framework for coordinating devices is proposed, it is called as WS-ECA(Web Services-ECA) framework. This framework was basically based on the web services and proposed the ECA based rule language, And this also proposed the framework that could enable the device coordination based on proposed rule language. In this paper, we propose the protocol among the components of WS-ECA framework to support dynamic feature for ubiquitous environment, and we also propose WSDL extension to support service and event descriptions these are provided in components of this framework.

A number of research studies focus on the efficacy of using such as scenario based learning. However, desirable methods have not been introduced to assess the scenario based learning. This article is to suggest a fuzzy logic based framework for scenario base learning in which more reasonable learning effects are measured. It can be solved uncertain problems of linguistic variables. Also, we suggest three measures of accuracy, comprehensibility and completeness in order to evaluate accurate effects of scenario based learning. This assessment provides the scenario to the learner in which the scenario is presented in an authentic context, and enable the learner to reach an outcome through an adequate sequence and choices. This approach enables the system to present new scenarios and outcomes based on what a user selects. In particular, the application of fuzzy logic in scenario based learning can be easily pursued certain successful path or wrong path all the way through to reach major outcome in real situation.

Facial expression and gesture of the actors can be magnified or understated depending on the size of the camera framing. The direction, quality, and quantity of the lighting can also make the actors look different. That's why we have to deliberate how to photograph the actors who will be projected on the screen. This thesis shows the way of improving performance and emphasizing each character with camera and lighting. You will also find out how visual elements influence the actors and their performances.

엔터프라이즈 컴퓨팅 환경에서 넘쳐나는 다양한 플랫폼과 언어, 프레임워크가 소프트웨어 개발에 대한 중복 투자를 야기하고 있다. 이종 플랫폼, 나아가 이종 개발 플랫폼을 자유로이 연동시킬 수 있는 개발 방법에 대한 필요성이 대두되면서 등장한 MDA 개념은 개발된 모델을 특정 플랫폼에 알맞은 형태로 변환함으로써 개발 모델 및 코드의 재사용성을 극대화한다. 본 논문에서는 MDA 개발 방법에 있어서 특정 플랫폼에 알맞은 로드를 동적으로 생성하면서 PSM 이나 프로그래밍 언어에 대한 중립성을 가지기 위한 방안으로 템플릿과 언어 처리기를 복합적으로 사용하는 방안을 제시한다.

딥러닝(Deep-learning) 기반의 자연어 이해(Natural Language Understanding) 기술들은 최근에 상당한 성과를 성취했다. 하지만 딥러닝 기반의 자연어 이해 기술들은 내적인 동작들과 결정에 대한 근거를 설명하기 어렵다. 본 논문에서는 벡터를 그래프로 변환함으로써 신경망의 내적인 의미 표현들을 설명할 수 있도록 한다. 먼저 인간과 기계 모두가 이해 가능한 표현방법의 하나로 그래프를 주요 표현방법으로 선택하였다. 또한 그래프의 구성요소인 노드(Node) 및 엣지(Edge)의 결정을 위한 Element-Importance Inverse-Semantic-Importance(EI-ISI) 점수와 Element-Element-Correlation(EEC) 점수를 심층신경망의 훈련방법 중 하나인 드랍아웃(Dropout)을 통해 계산하는 방법을 제안한다. 다양한 실험들을 통해, 본 연구에서 제안한 벡터-그래프(Vector2graph) 변환 프레임워크가 성공적으로 벡터의 의미정보를 유지하면서도, 설명 가능한 그래프를 생성함을 보인다. 더불어, 그래프 기반의 새로운 시각화 방법을 소개한다.

현재 선천적인 청각장애인이나 언어 장애가 있는 사람은 다른 사람과의 대화에 많은 불편을 겪고 있다. 매장을 이용하기 어려움은 물론 언어전달 능력이 떨어지기 때문에 간단한 의사소통을 통한 서로 간의 교류 또한 불편함을 감수해야 한다. 현재는 따로 디스플레이가 내장된 장치를 이용하여 지정된 장소에서 수화를 번역해야 하는 불편함을 해당 문제 해결을 위해 본 연구에서는 딥러닝을 적용하여 수화를 인식하고 번역하여 디스플레이에 텍스트를 출력해주는 시스템을 개발하였다. AI 프레임워크 MediaPipe와 SVM 알고리즘을 라즈베리파이에 적용하여 구현하였다. 개발한 시스템은 제스처에 대한 번역 결과를 제공한다. 기존의 지정된 장소가 아닌 대화가 필요한 모든 장소에서 번역이 가능하도록 개선하여 청각장애인과 언어장애가 있는 사람들과 소통의 불편함을 줄일 수 있을 것으로 기대할 수 있다.

The reuse by using framework is proposed to improve productivity. It is a set of usable and expandable classes and their connectivity. But frameworks are described with programming languages, it is hard for developers to learn the collaborative patterns of a framework by reading it. Patterns are one approach to improving the documentation. But this should be redesigned to expand and redefine the framework. The necessity of the formal description of architecture information is being proposed to relate to programming language. This paper support the following points. First of all, it has been proposed the description of the needed elements when developing a framework using ADL. Secondly, the current development process has been refined to be suitable for developing the domain framework. Thirdly, it has been proposed the development of a application using a framework implemented by an architecture information described with ADL. Overalls, the main contents of this research is defining the ideas of a description and development of an architecture framework using ADL.
