The most typical roles of libraries in their information societies are public access points to the networks, providing teaching and training, assisting in knowledge resource discovery, and knowledge providers. In order to fulfil these roles, libraries should be a ky element in national and local cultual policies. Effective policy making is the most important responsibility of libraries as well as national and local governments and one of library management tools for running the library. The purpose of this study is, therefore, to review the spectrum of the library and information policies in Korea and suggest some desirable directivities for library policy making.

Based on the 'Government 3.0', the government opens the public data and encourages the active use in the private sector. Recently, the spatial and statistical information that is one of the public data is being widely used in the various web business as a high value-added information. In this study, we propose an architecture of high-availability, high-reliability and high-performance open platform which can provide a variety of services such as searching, analysis, data mining, and thematic mapping. In particular, we present two different system architectures for the government and the public services, by reflecting the importance of the information security and the respective utilization in the private and public sectors. We also compared a variety of server architecture configurations such as a clustered server configuration, a cloud-based virtual server configuration, and a CDN server configuration, in order to design a cost- and performance-effective spatial-statistical information open platform.

A case study to test the open API service functions of Geographic Information Open Platform(Vworld) for Environmental Impact Assessment was carried out for improving the function of Environmental Impact Assessment Geographic Information System(EIAGIS) which is one of Environmental Impact Assessment Supporting System(EIASS) used for current Environmental Impact Assessment. Followings are the summary of the study. First, utilization of EIAGIS was low since DB renewal was limited and the quality of 2D based topographic information was low. A new service which could respond to practitioners' needs could be developed to use a open API service of Vworld provided by the Ministry of Land, Infrastructure and Transport to make up those disadvantages. EIASS with Vworld could provide a consulting service from the beginning stage of business plan and make improvements of confidence as well as fast agreements since both consultation agencies and assessment agencies are using a same program during Environmental Impact Assessment process with customized information.

ADCP는 매우 상세한 유속 및 하상자료를 측정할 수 있어 하천의 수리학적 계측에 많은 가능성을 열어주고 있다. 하지만 현재까지 대부분 하천 단면에서의 유량 측정에 국한되어 운영되고 있는 실정이다. 본 연구에서는 ADCP가 제공하는 원자료인 3차원 유속과 하상자료를 유량 외의 평균유속장 및 하상 계측에 활용될 수 있도록 하는 후처리 소프트웨어 개발을 통해 ADCP가 하천의 흐름해석 및 2차원 및 3차원 수치모델의 검보정 등에 활용될 수 있는 가능성을 보이고자 한다. 따라서 계측 방식도 하천의 단면뿐만 아니라 하도에 따른 지그재그 방식의 자료를 포괄한다. ADCP 자료의 후처리는 제작사에서 제공하는 소프트웨어가 유량 제공에 초점을 맞춰 다른 분야에의 활용을 위해 별도의 후처리 소프트웨어의 제작이 필요하나 자료구조가 까다롭고 수십에서 수백 개의 파일을 동시에 처리할 수 있는 툴의 개발은 용이하지 않아 ADCP를 흐름분석 등에 활용하고자하는 연구자나 관계 기관종사자들에 한계로 작용하였다. 또한 제작사 (RDI, SonTek)에 따라 원자료의 구조가 완전히 달라 한꺼번에 처리하는 데 많은 문제가 있어왔다. 본 연구를 통해 개발된 툴은 두 제작사의 ADCP 원자료 포맷으로 구성된 다수의 관측 파일도 동시에 처리할 수 있다. 또한 GIS 기반에서 ADCP 자료의 위치를 표출할 수 있어 지형정보와 결부된 흐름장 해석이 가능하게 한다. ADCP 3차원 속도자료는 매우 정밀한 공간에서 측정되는 부분이 장점인 반면에 지나치게 정밀하고 또한 난류 등이 포함되어 원자료 만으로 흐름장을 분석하는 데 한계가 있다. 따라서 본 연구에서는 다양한 공간평균방법을 제공하여 2차원 및 3차원 공간에서의 공간보간된 평균유속장을 볼 수 있게 하였다. 이러한 방식은 2,3차원 수치모델의 격자에 ADCP 유속자료를 보간할 수 있어 모델 검보정에도 활용될 수 있다. ADCP 원자료 및 후처리된 결과는 GIS, Excel, Google Earth 파일 형태 등으로 제공될 수 있어 추후 활용가능성을 높였다.

Due to the improvement of surveying, mapping and communication techniques, various apps for road direction guides and vehicle navigations have been developed. Although such a development has impacted on walking and driving, there is a limit to improving the daily convenience of the socially impaired people. This is mainly due to the fact that the software have been developed for normal pedestrians and drivers. Therefore, visually impaired people still have problems with the confusion of direction and/or non-provision of risk factors in walking. This study aimed to propose a scheme which constructs data for mobility-impaired or traffic-impaired people based on various geospatial information. The factors and components related to walking for the visually impaired are selected by geospatial data and a walking route guidance network that can be applied to a commercial software. As a result, it was confirmed that road direction guidance would be possible if additional contents, such as braille blocks (dotted/linear), sound signals, bus stops, and bollards are secured. In addition, an initial version of the application software was implemented based on the suggested data model and its usefulness was evaluated to a visually impaired person. To advance the stability of the service in walking for the visually impaired people, various geospatial data obtained by multiple institutes are necessary to be combined, and various sensors and voice technologies are required to be connected and utilized through ICT (Information and Communications Technologies) technology in near future.

The roles and services of a library have historically been influenced and developed by the change of information technologies. The ubiquitous technologies have been widely studied for medical area, construction, commerce, broadcasting, telecommunication and so on. The ubiquitous technologies have extended to the roles and services in a library. The development of ubiquitous IT, the roles and functions of a library and information center should be changed. To adjust evolving environment, this study focuses on concept and definition of ubiquitous computing and networks. Especially, with requirements and essential technologies which can be a technological infrastructure for ubiquitous life, library services and roles in ubiquitous life are discussed by literature review, case analysis and expert interview. With the results, this study proposes that library services and roles in ubiquitous life should be considered in two ways which are network and physical spaces. Also, roles of a library in ubiquitous life will be extended to culture and education center including traditional information center. To perform those roles and services, a library should develop various service programs relating culture and education such as personalized service and educational program.

하천은 이수, 치수 및 환경 등의 역할을 수행하며 문화생활의 공간 제공, 재해예방 기능, 생활용수 공급 등 다양한 형태로 국민의 생활과 문화의 발전에 기여한다. 국내에는 총 5,937개의 하천이 존재하며, 정부는 매년 많은 예산을 투자하여 다양한 하천사업을 추진 중에 있다. 하천사업의 경우 국토교통부, 환경부, 행정안전부를 중심으로 하천수변공간의 복원, 홍수예방 등에 관한 사업을 수행해 왔으나 현재 지방의 자율성, 책임성과 권한확대를 위해 지방하천 관련 사업들의 경우 각 지자체로 기능이 이양되고 있으며 국가하천을 대상으로 한 사업만을 중앙정부기관에서 관리하는 중이다. 그러나 중앙정부 기관에서 관리 중인 국가하천 관련 사업들에 대한 관리 또한 수월하지 않아 사업 현황관리, 예산 관리 등에 대한 필요성이 지속적으로 제기되는 실정이다. 한편, 국내에서는 수자원관리를 위한 시스템인 하천관리지리정보시스템(RIMGIS)과 국가수자원관리종합정보시스템(WAMIS)을 운영 중에 있으나 하천에 관한 제반사항 및 하천기본계획 등의 관리만을 수행하며 하천공사관리는 포함하고 있지 않다. 따라서 본 연구에서는 하천사업(공사)관리 시스템 개발 방안을 제시하고자 한다. 이는 중앙부처에서 관리 중인 국가하천 관련 사업의 체계적인 관리와 사업수행 중 발생 가능한 문제 상황 대응력을 향상시켜줄 것으로 기대한다.
