This research analyzes the revised philosophy class in the 5th Edition of Korean Decimal Classification. It depends on the 1st Edition of KDC despite of the fact that contents and words were revised and changed, numbers for classification were moved, and indices were removed from the previous Edition of KDC. The object of the 5th Edition of KDC, metaphysics and eistemology are organized in the same sub-class(綱) through modifying, sex psychology, development psychology, physiognomy fortune judgment, applied psychology are expanded that its data are increasing in psychology, ethics, moral philosophy are modified.

Measurement of quality of life is a concept studied in the field of administration, economy and society. And It is a standard of measuring performance of government. Recently, in governments and global society, QoL (Quality of life) index is used to reflect overall development degree. National policy and service effectiveness measurement using QoL index is more persuasive when it is combined with 'Bottom-Up Spillover Theory'. This study applied "National Quality of Life Index", the object QoL index used by National Statistical Office to see if the library service is recognized to actually have influence on the quality of life, and furthermore, see the difference of quality of life improvement recognition by user and quality of life improvement degree recognized by the librarian. "Recognition regarding shortage of time" was the highest index, and "concentration of fine dust" was the lowest. Regarding the recognition difference between librarian and user, it showed signifiant difference in 13 index, while the recognition difference by gender showed difference in 5 index, difference by age was 23, difference by residence was 14, and difference by number of visits to library was 9.

An agent is an abstract unit for problem solving in the field of distributed artificial intelligence, and an agent-based system is designed and implemented based on the definition of agent as its central concept. Agent modeling is advantageous to abstraction, disintegration and structuring for describing complex system, so its application is increased in various areas including air traffic control, power transmission, e-commerce and medicine. There is no agreed definition of agent but agents have common points as follows: autonomy, reactivity, pro-activeness and cooperation. An agent-oriented modeling is an approach of a concept different form existing object-oriented modeling. This study proposed the agent application for E-Beam manufacturing system. To evaluate the performance of the proposed process design, we used the JADE library. The JADE toolkit provides a FIPA-compliant agent platform and a package to develp Java agents. It provides a basic set of functionalities that are regarded as essential for an autonomous agent architecture.

This study proposes an integration model of information retrieval systems using a standard distributed object computing technology in digital library environments. In the proposed integration model called DDIRIORB, the middleware broker based on CORBA is designed for the transparent access to the distributed information repositories and the consistent view of the information retrieval by applying 239.50 protocol. The DDIRIORB is an adaptable open architecture that allows for the following benefits : bibliographic and abstract information retrieval simultaneously, interoperability between application servers and clients, consistent view of search results, complexity reduction of integration interfaces, and easy to use.

The clustering characteristics for a number of classes, and defining the inheritance relations between the classes is a difficult and complex problem in an early stage of object oriented software development. We discuss a traditional iterative approach for the reuse of the existing classes in a library and an integrated approach to creating a number of new classes presented in this study. This paper formulates a character-istic clustering problem for zero-one integer programming and presents a network solution method with illustrative examples and the basic rules to define the inheritance relations between the classes. The network solution method for a characteristic clustering problem is based on a distance parameter between every pair of objects with characteristics. We apply the approach to a real problem taken from industry.

When we present some information, we can use application programs through multinedia-based authoring tools. Especially.many programers proposed to improve its intergration time and reduce programming speed and easy to use. However, multimedia based authoring tools have not all of programming methodolgies and do not supply special functions from user's request. Therefore, we have to apply effective functions through high-level programming languages.In this paper, we propose to use small appkication prograns through linking methods, So we reduce overhead from memory loading In authoring tools, we can use MCI(media control interface) call functions for playback audio files.we development ATS(Auto Transition System) for several functions-close MCI call audio files, get object status, page-to page trancition.We evidently show that an optimal configuration of presentation obtained by ATS algorithm.

The SQL CLl (Call Level Interface) is a database application programming interface (API) that fits the client-server environment, and its de facto standards such as ODBC and JDBC are widely employed in various applications. The current SQL CLl standards, however, do not specify enough features for efficient retrieval of large objects (LOBs) that constitute the multimedia data. In this paper, we propose the LOB caching through the SQL CLl and describe the extension of the SQL eLl to achieve such a goal. We implement our proposal by extending the SQL CLl library for BADA - II DBMS developed at ETRI, and evaluate the performance of LOB retrieval through the cache compared to that of LOB retrieval conducted solely with the functions specified in the current SQL CLl standards.

Object-oriented software, reusability enables to specialize the software techniques by leading the user friendly thought and meets the user's need only concentrating on convenience of development environment. Reuse effect can be maximized through retrieval system. In this paper, we development the MT-Views(Multiple-Template Views) to realize the reuse effect as integrated reuse system including retrieval, understanding and rebuilding tools based on class library. We used the hybrid retrieval model for easy and efficient retrieval of similar software components. With using these tools, users can retrieve the reusable components and reuse the components for constructing therir own applications. Also, we can acquire many informations about retrieved components, so can rebuild components conforming our original intend.

본 논문에서는 모바일 기반 OpenCV 라이브러리를 이용한 마커리스 객체 인석 성능 향상을 위한 소프트웨어적인 관점의 방법을 제안한다. 기존의 마커리스 기반 알고리즘을 이용하여 테스트를 수행한 후 성능에 저하를 발생시키는 요인들을 분석하고 그에 따른 상황별 적절한 해결책을 제시한다. 이에 따라 크게 프로그램 코드 개선, 마커리스 기반 알고리즘 코드 개선, 센서를 활용한 성능 향상을 도모한다. 프로그램 코드 개선은 테스트 결과를 분석 한 후 수행시간이 가장 많이 소요되는 함수를 최적화하고 또한 최적의 특징점의 수를 제한한다. 마커리스 기반 알고리즘 코드 개선은 병렬 처리가 제공되는 모바일에 한하여 병렬처리기법으로 코드를 수정한다. 마지막 센서를 활용한 성능향상은 실시간 작업 처리 단위를 묶음으로 처리하였을 때 발생하는 품질의 저하를 보정하는 역할을 수행한다. 본 논문에서는 이러한 마커리스 객체 인식 성능 향상 방법을 소프트웨어적인 관점에서 제안하고 이에 대한 결과 모바일 기반 실시간 증강현실 서비스를 위한 성능 향상 면에서 효과적이다.

This paper describes a 3-DTIP(3-D Tour Into Picture) using depth map for a Korean classical painting being composed of persons and landscape. Unlike conventional TIP methods providing 2-D image or video, our proposed TIP can provide users with 3-D stereoscopic contents. Navigating inside a picture provides more realistic and immersive perception. The method firstly makes depth map. Input data consists of foreground object, background image, depth map, foreground mask. Firstly we separate foreground object and background, make each of their depth map. Background is decomposed into polygons and assigned depth value to each vertexes. Then a polygon is decomposed into many triangles. Gouraud shading is used to make a final depth map. Navigating into a picture uses OpenGL library. Our proposed method was tested on "Danopungjun" and "Muyigido" that are famous paintings made in Chosun Dynasty. The stereoscopic video was proved to deliver new 3-D perception better than 2-D video.
