한국 수화는 한국어에 대한 기본적인 유사성을 가지고 있지만, 교착어이자 청각-음성 체계 언어인 한국어와는 달리 고립어이자 시각-운동 체계 언어로서의 특성을 동시에 나타내고 있다. 그러므로 텍스트 형태의 한국어 문장으로부터 수화를 자동 생성하기 위해서는 한국어를 위해 미리 정의된 문법에 수화 표현을 무리하게 연계시키려고 하기 보다, 수화 고유의 의미 전달 체계를 분석하고 활용하여야 할 필요가 있다. 본 논문에서는 수화 표현상의 언어학적 특징을 재현 생략 변형 이동의 네 가지로 구분하여 분석하고 결합범주문법을 이용한 이 같은 형상의 처리 방법 및 구현 방안에 대하여 논의한다.

By employing the subscriber concept in broadcasting services, IPTV (Internet Protocol Television) operators provide various grades of services to subscribers based on the billing level of the subscribers. With the income from subscribers for a basis, IPTV operators plan to provide high quality services. Since Web browser-based IPTV provides T-commerce and E-commerce services as well as television services, users may frequently visit other service domains to buy goods or content. To provide the user with charged or private services, these service domains request authentication of user. The existing authentication system is not appropriate for the IPTV service environment because the environment unavoidably forces the user to cross from one authentication-based service domain to another. Single sign-on provides a user with transparent authentication services by enabling an authenticated user to move between authentication-based service domains without any re-authentication. Like this distributed environment, since the IPTV service environment also provides a variety of authentication-based services, transparent authentication service needs to be provided to subscribers who want to access charged or private services. In this paper, we propose a new user authentication scheme for the IPTV environment. This scheme integrates the Security Assertion Markup Language (SAML), which is a standard for XML-based single sign on. We validate this scheme using a simple use case scenario.

Railway sign(graphic sign, diagraphics) designs require good recognition with universality to transmit accurate and speedy information as they connect people around the station and other transport systems. An important point of signs is how to design and deliver the contents to the viewers as a communication service tools. It needs to establish design guidelines with standardization and unified system to show their contents and images clearly like common language with visuality, attractivity and generality. These requisites are important for both aesthetics legibility and unified standards to maximize the effectiveness of pictograms for the use of the general public, who require systematic suggestion and management.

The study began in recent years with the aim of grasping the nation's medical status following the fast-growing trend of international medical tourism and attracting foreign patients, among other things, Busan, which ranks second in attracting foreign patients after the nation's capital, Seoul, has been highly active in the past eight years, with foreign patients rising by about 426 percent, and Russian patients entering the sea. In addition, Gimhae and Changwon, the Busan-based Gyeongsangnam-do region, ranked first and second in number of foreign residents, and are inhabited by a variety of foreign workers. Medical institutions, such as hospitals, should be able to find directions within hospitals. It is also a space where information in various languages, including Korean, English, Chinese, or Russian, must be delivered in a single medium. Based on this research, the purpose of this research is to provide converged information that helps foreigners who are not familiar with Korean language easily understand the proposed recognition system when visiting hospitals. Therefore, this paper is applied to a multi-language survey of six medical institutions (A, B, C, D, E, F) at the university hospital in Busan, and 10 medical institutions (R, J) in Gimhae, South Gyeongsang Province with high foreign residents. Research results and contents are as follows. First, the results of analyzing the design of the sinusoidal system show that the font uses colorless Gothic fonts, arrows, and pictograms to introduce the design of a typical hospital sign system. Second, the results of the multi-lingual situation were found to have only two languages in the system, such as Korean and English, and to have four languages, including Korean, English, Chinese, and Russian, according to their geographical location. However, it was judged that most medical institutions currently have only two languages (Korean, English) that may cause some discomfort in terms of language for foreign patients in non-English speaking countries. Based on these findings, it is necessary to propose designs that are considered by Koreans as well as foreign users in the use of multilingual hospital sign systems.

영상 처리를 통한 수화(手話)의 인식에 있어 가장 중요한 정보는 손의 형상, 위치, 이동방향 등을 들 수 있다. 이 중 손의 형상은 세가지 정보 중 가장 중요하며, 실제로 자음과 모음, 숫자 등을 나타내는 지문자의 경우 손의 형상만으로도 인식될 수 있다. 본 논문에서는 선 처리 모델(Line Process Model)을 3차원으로 확장하여 적용한 Markov Random Field(MRF)를 사용하여 효율적으로 손의 형상을 추출하였다.

SAML(Security Assertion Markup Language)은 웹 서비스 환경에 최적화된 인중과 권한 부여를 표준적이면서도 확장성 있는 구조를 제공하는 공개된 표준이다. ebXML과 같은 공개된 XML 기반 거래 프레임워크에 SAML을 적용함으로써 기업 간 협력형 비즈니스 모델 내어서 문제가 되었던 550(Single Sign-on)를 위한 사용자 관리 및 인증의 부담을 최소화 할 수 있다 본 연구에서는 SAML에 대한 기술 분석과 함께 ebXML 및 웹 서비스 비즈니스 트랜잭션 내에서 적용 방안을 논의하고 원 서비스 모델 기반의 SAML 인증 시스템을 제시한다.

인터넷에서 비지니스 파트너 사이에 보안 정보를 교환하는 XML 프레임워크인 SAML (SecurityAssertions Markup Language)은 국제적 컨소시엄인 OASIS(the Organization for the Advancement of Structured Information Standards)에 의해 제정된 표준이다. SAML은 S2ML(Security Services Markup Language)의 원리와 구조를 재사용하고, 신뢰할 수 있는 Single Sign-On, 인증 서비스, B2B이션 서버, XML 메시징 프레임워크와 다양한 오퍼레이팅 플렛폼사이에 인증, 승인과 함께 프로필 정보를 교환하기 위해 사용된다. 본 논문에서는 SAML의 기반으로 인터넷에서 여러 기업들이 보안문서를 교환할 때 여러 가지 솔루션과 함께 쓰고 공유하는 안전한 언어에 대해서 논한다
