정보취약계층을 위한 도서관 서비스 활성화 방안에 관한 연구
이 연구에서는 우리나라 공공 도서관에서 적극적으로 수용해야할 정보취약계층에 대한 정보서비스 확산을 위해 필요한 개념과 기본적인 정보서비스 전략을 제안하였다. 공공도서관은 정보취약계층을 크게 장애인과 생활보호대상자, 노인 등으로 구분하여 각 계층의 특성을 고려한 정보서비스를 제공하여야 한다. 이들을 위...
Reference services in the commons environment
Purpose – This paper describes the services offered in an information commons that primarily serves undergraduate students at a large research university. This paper provides background information on the implementation of a learning or information commons and describes the effect of the commons environment on reference services and environment and highlights the importance of a strong relationship between libraries and information technology providers in developing successful public services in an information commons.Design/methodology/approach – This article describes the transformation of an Undergraduate Library into the Information Commons and describes the implications for library services in a public services partnership.Findings – The information commons environment is one part of a library system that is evolving in response to and in anticipation of user needs.Practical implications – This paper documents a successful partnership in creating an information commons that primarily serves undergrad...
Effect of temperature on optical fiber transmission.
Results are presented concerning the effects of temperature on the transmission properties of various optical fibers including a silicone plastic clad, an acrylic plastic clad, and CVD step-index fibers both with and without polyurethane jackets. Results are presented for the normalized transmitted power vs temperature, the index of refraction vs temperature, and induced attenuation coefficients vs temperature. The data show that the intrinsic transmission of a CVD fiber is independent of temperature over the -110 to +150 C range. Plastic clad fused silica fibers are subject to transmission losses at lower temperatures due to changes in the optical index of the cladding polymer. Acrylic-clad and plastic-clad silica fibers also show transmission losses at lower temperatures, but to lesser extents.
