The purpose of this study is to clarify the case and process of the application of the sign system in order to enable the user to reach the target site more efficiently in the library. For this purpose, a new sign system was applied to the S University library through procedures such as library structure, sign status, user observation, cyan production and preference survey. Detailed production process and user's reaction were identified. Based on this we suggested improvements to the library stacks signage system.

The National Library of Korea installs and operates various signs for the purpose of efficient use of visitor and information transmission. In this study, the present status of the existing signatures of the National Library of Korea was surveyed and the satisfaction survey was conducted for the patron and staff. Based on this, we suggested the improvement of visual continuity (connectivity), changing the installation location, reduction of excess sign, limitations of temporary attachment signatures, and easy to understand contents as user's guide to efficient library use and improvement of National Central Library sign system.

The user has to subscribe to the library so that user use the library service. User has to register at that in order to use of the nearby another library. Moreover, service such as the inter-library loan and returning my loan book to other library in which the mutual cooperation between the library is needed necessity. But it services due to the constraint condition because of the administrative or technical problems. In this paper excludes the administrative element. The web service model is forming the cluster based on the mutual cooperation between the technologically adjacent public library and provides the technologically necessary single sign-on (SSO) in order to support the additional service. The single sign-on of the library which is concluded by this model using the security information exchange standard (Security Assertion Markup Language : SAML), it is processed by XML base. In using this model, the loan information is confirmed in the attribution in return service library and the model can utilize for the return of loan book in other library. It designs the single sign-on about it.

Single Sign-On(SSO)은 사용자가 단 한번의 인증으로 분산된 시스템에서 제공하는 다른 서비스에 로그인하는 것을 가능하게 하는 보안 특징이다. SAML은 서로 다른 entity들 사이에서 인증, 권한 그리고 profile 정보의 교환을 가능하게 하는 XML기반의 SSO표준이다. 이러한 표준은 분산 환경에서 서로 다른 보안 서비스들 사이에 상호운용성을 제공한다. 본 논문에서는 SAML APIs로 구성된 자바 기반의 SSO library를 설계 및 구현하고 SAML APIs를 검증하기 위해 분산 application의 prototype을 구성하였다. 개발된 library에서 무결성, 부인방지, 그리고 기밀성 같은 보안고려사항들을 XML기반의 서명과 암호화를 적용하여 보장한다.

In this paper, we implemented a sign language communication system between korean and japanese using 3D model. Unitl now, we have developed the system through 2D image. The system, however, has some drawbacks base don the limitations of 2D model. Especially it is not comprehensive in the sign language gesture including forward or backward movements becasue it can only display a front view. Therefore, we employed a 3D model for the representation of sign language. The proposed communication system si implemented with windows 95 visual C++ 5.0 imported open inventor library on pentium 233 system. Experimented results show that the 3D system can solve the problems in 2D representation.

This paper presents a design of a speech to sign language converter for deaf and hard of hearing people. The device is low-cost, low-power consumption, and it can be able to work entirely offline. The speech recognition is implemented using an open-source API, Pocketsphinx library. In this work, we proposed a context-oriented language model, which measures the similarity between the recognized speech and the predefined speech to decide the output. The output speech is selected from the recommended speech stored in the database, which is the best match to the recognized speech. The proposed context-oriented language model can improve the speech recognition rate by 21% for working entirely offline. A decision module based on determining the similarity between the two texts using Levenshtein distance decides the output sign language. The output sign language corresponding to the recognized speech is generated as a set of sequential images. The speech to sign language converter is deployed on a Raspberry Pi Zero board for low-cost deaf assistive devices.

This study unpackes semiotic character of knowledge classification and wants to know how sign structure of classification effects on canon and banned book etc, and by this impact stems from the semoitic structure structurally, discusses coidentity between banned book and internet in social and cultural structure aspect. and proposes way for understanding and interpretation text like mass media using structuralism theory.

This study attempts to identify users' potential information needs in a medium-sized academic library by analyzing reference questions raised by library users for 64 days from October 10th to December 13th, 2000. A total of 474 reference questions were analysed of which only 10.1% were pure reference questions that dealt with the professional knowledge of reference librarians. 71.0% had nothing to do with professional knowledge, being directional(29.3%), mechanic(23.8%), and library policy related(l7.9%). Improvements in sign system and guiding materials in the library should be made to deliver reference services of good quality to academic library users.

본 연구의 배경은 공공도서관 사인시스템의 현황과 지속적인 활용에 있다. 수많은 정보 중 필요한 정보를 선별하고 수용하는 것이 중요한 현대사회에서 사인시스템은 원만한 상호작용을 위한 주요수단이다. 특히 복잡한 구조와 공간의 기능을 함께 지니고 있는 도서관에서 정보를 파악하기 위해서 명확한 지각효과를 갖춘 사인의 역할은 무엇보다 중요하다. 이에 따라 본 연구는 이용자가 공공도서관을 이용할 때 어떠한 요소가 정보를 수용하고 시각적으로 인지하는데 많은 영향을 미치는지 알아보고자 한다. 그리고 선정된 도서관을 대상으로 기능 및 시각적 요소에 따라 사례분석을 한 후 이용자 만족도 조사를 실시하여 효과적이고 편리하게 도서관을 이용할 수 있도록 정보를 제시하는데 목적이 있다.
