정보 보안의 요소는 인가되지 않은 사람이 시스템에 액세스(Access)하거나 인가없 이 사용하는 것을 방지하는 액세스 통제이다. 이를 위해서 정보의 기밀정도에 따라 보호정 도를 결정하는 기밀등급분류가 이루어져 정보를 선택관리하는체계가 이루어 져야한다. 정 보를 선택관리하기 위해서는 보호할 만한 정보를 식별하고, 식별된 중요정보를 어떤 방법 으로 유지, 관리, 이용할 것인지를 규정하는 것이 필요하다. 본 논문에서는 정보 기밀등급 의 체계적인 분류방법에 대해 살펴보기로 한다.

This study was performed in order to derive components that librarians think preferentially necessary and realistically important when applying the NCS 'Library and Information Administration's duty' to the library working environments. It was possible by evaluating and analyzing the importance and utilization of ability unit and its element which are the components of NCS 'Library and Information Administration's duty'. First, ability units of 'User Information Services', 'Reading and Culture Programs' were higher in importance and utilization at the same time. Ability units of 'Library and Information Practical Research Perform', 'Library and Information Curation', 'Library and Information System Operation' were lower in importance and utilization when we evaluate the importance and utilization of ability unit and its element which are the components of NCS 'Library and Information Administration's duty'. Second, components of 'Reading and Culture Programs', 'User Information Service', 'Library and Information Collection' were higher in the order, and components of 'Library and Information Curation', 'Library and Information System Operation', 'Library and Information Practical Research Perform' were found lower in demands as the desirable level and the current level appear less common when we analyzed the demands on the duty components utilizing Borich requirements analysis model. Third, six ability units of 'Reading and Culture Programs', 'User Information Services', 'Library and Information Collection', 'Library and Information Services Marketing', 'Library and Information Preservation', 'Library and Information Use Analysis' were derived as priority components when we analyzed the priority of the duty component (ability unit) utilizing The Locus for Focus model.

Flooding usually brings in disruptions and aggravated congestions to the roadway network. Hence, right information should be provided to road users to avoid the flood-impacted areas and for city officials to recover the network. However, the information about individual link congestion may not be conveyed to roadway users and city officials because too many links are congested at the same time. Therefore, more significant information may be desired, especially in a disastrous situation. This information may include 1) which places to avoid during flooding 2) which places are feasible to drive avoiding flooding. Hence, this paper aims to develop a framework to identify the flood-impacted areas in a roadway network and their criticality. Various impacted clusters and their spatiotemporal properties were identified with field data. From this data, roadway users can reroute their trips, and city officials can take the right actions to recover the affected areas. The information resulting from the developed framework would be significant enough for roadway users and city officials to cope with flooding.

To understand present road state quickly and correctly, The Ministry of Construction and Transportation pushing on with their plan that they offer digital images to user with position information in the HMS(Highway Management System). For that plan, the Korea Institute of Construction Technology developed a highway photologging vehicle which could acquire two high resolution color CCD images with fixed distance on the way to run. In this paper, especially, development of image aquisition S/W and synchronization device are described. And also their performance and trajectory accuracy are investigated together. As a result, it could be hon that the newly developed highway photologging vehicle is suitable to the road image acquisition work far the HMS.

In statistical process control, the primary method used to monitor the number of nonconformities is the c-chart. The conventional c-chart is based on the assumption that the occurrence of nonconformities in samples is well modeled by a Poisson distribution. When the Poisson assumption is not met, the X-chart is often used as an alternative charting scheme in practice. And CUSUM-chart is used when it is desirable to detect out of control situations very quickly because of sensitive to a small or gradual drift in the process. In this paper, I compare CUSUM-chart to X-chart for the Katz family covering equi-, under-, and over-dispersed distributions relative to the Poisson distribution.

The database design, which logically sets the base structure and orga¬nization of the database, is performed by considering the users requirement, the relations between various data, and the relations between data and application field.The road network data must be created to have geometrical topological structure, because various data elements are needed to recognize the state of each section and to relate between data element. In this study, we propose a method of creating the road network database for an integrated road management system.

The need for unified graphic base with high accuracy for nation¬wide is emerging since many facility management organizations and local governments have been taking steps for introducing facility management systems from the late of 1980's. A major finding of the above efforts was the importance of establishment of National Land Information System supporting all land management and use, administration purpose and effective decision-making. So to meet the recent need and to prepare future information society, a study is going on progress for in t roduc i ng Parce I-Based Land In forma t ion Sys tern based on I arge-sca I e cadastral graphic data and parcel information, capable to link with admini¬stration, communication, statistics etc.
