최근 다양한 관점에서의 사회관계망 분석이 확대되면서 R&D분야도 연구자 간의 네트워크를 이해하고자 하는 요구사항도 증가하고 있지만 국내에서는 연구자나 과학자 사이의 네트워크 분석 및 서비스에 대한 시도가 다양하지 않은 상황이다. 본 논문은 국내 R&D분야의 사회관계망에 대한 이해증진을 위하여 구현한 공저자 네트워크 가시화 서비스에 대한 기술이다. 사회 관계망 분석과 서비스를 위하여 동명이인 저자를 식별하고 이들 간의 공저자 관계를 계량정보 분석기법을 이용하여 분석하였으며 연구자들 간의 네트워크를 쉽게 조망할 수 있도록 정보를 가시화 하였다. 본 논문에서 구현한 공저자 네트워크 서비스는 국내 연구자들 간의 협업형태를 직관적으로 이해할 수 있도록 하며 각 연구 분야의 핵심연구자 및 다양한 연구 분야를 연계하는 허브 연구자의 확인을 용이하게 한다.

As a way to gather diverse information required for everyday living, the importance of social networks has been growing. Social network services have been spreading rapidly because of diffusion of the Internet, evolution of social network sites, and recognition of the importance of social networks. Recently, the social network service has been evolved based on a new paradigm, Web 2.0, pursuing participation and openness. Following the adoption of Web 2.0 technologies, the social network service allows users to make and maintain new relationships in a more convenient way. Users of the social network service tend to reveal their personal information, and share their ideas and content with other people; in the process they become aware of their existence, feel satisfaction with life and exert influence to others as a member of the society. This study uses higher order factor analysis to analyze factors that affect the intention of using the social network service. A research model was developed with second-order factors including perceived social presence, perceived gratification and perceived social influence. First-order factors are grouped by technical, individual and social factors. Smart PLS 2.0 was used to conduct empirical analysis. The analysis results supported the validity of the research model.

정보통신 발달로 유선 네트워크과 무선네트워크의 융합에 대해서 학계나 산업계에서는 이미 자연스럽게 물리적 공간간 융합이 되고, 현재는 서로 다른 유무선 및 방송 서비스간의 대융합도 새삼스러운 일들이 아닌 것처럼 변해 버렸다. 현재의 발전상으로 보아 진정한 정보사회에서는 컴퓨터와 인간생활 중심으로 새로운 네트워크 창조과정에 정보통신과 도로, 차량, 휴먼이라는 네트워크 상호간의 다른 새로운 가상 네트워크를 통하여 다양한 생활양식이 도입되는 사회 실현은 자연스러울 것임은 틀림없다. (중략)

사회 전반에 걸쳐 소셜네트워크서비스의 영향력이 높아짐에 따라 국내 대학도서관에서도 소셜네트워크서비스의 도입을 통해 이용자와 소통하려는 노력을 하고 있다. 이에 본 연구에서는 국내 대학도서관의 소셜네트워크서비스의 현황을 파악하고 소셜네트워크서비스의 이용률이 높은 도서관과 낮은 대학도서관을 선정하여 이용 및 비이용 요인을 도출하는 것을 통해 활성화 방안을 제시하였다.

홈 네트워크 서비스 산업은 미래의 국가발전과 새로운 변혁의 원동력으로서 향후 발전 가능성이 매우 크다고 할 수 있으나, 홈 네트워크 서비스의 보급이 확산되고 다양한 형태의 홈 네트워크 서비스가 등장하면서, 사이버공격의 대상 범위 또한 확대되어 사회적, 경제적으로 우리 사회에 큰 불안 요소로 작용할 가능성이 있고, 홈 네트워크 서비스의 침해사고 발생을 방지하고 사용자의 정보가 노출되지 않는 사용자 인증이 필요하다. 본 논문에서는 OTP를 기반으로 한 인증서를 이용하여 홈 네트워크의 보안요소 중 사용자 인증과 접근제어에 관하여 연구 하였으며, 인증 서버와 클라이언트 간에 동기화된 OTP 난수 값으로 인증서 정보를 암호화 하여, 외부 공격으로부터 보다 안전한 사용자 인증 기법을 제안한다.
