The authors argues that the current road updating system based on traditional aerial photograph or multi-spectral satellite image appears to be non-user friendly due to lack of the frequent cartographic representation for the new construction sites. Google Earth are currently being emerged as one of important places to extract road features since the RGB satellite image with high multi-temporal resolution can be accessed freely over large areas. This paper is primarily intended to evaluate optimal threshold of RGB pixel values to extract road features from Google Earth. An empirical study for five experimental sites was conducted to confirm how a RGB picture provided Google Earth can be used to extact the road feature. The results indicate that optimal threshold of RGB pixel values to extract road features was identified as 126, 125, 127 for manual operation which corresponds to 25%, 30%, 19%. Also, it was found that display scale difference of Google Earth was not very influential in tracking required RGB pixel value. As a result the 61cm resolution of Quickbird RGB data has shown the potential to realistically identified the major type of road feature by large scale spatial precision while the typical algorithm revealed successfully the area-wide optimal threshold of RGB pixel for road appeared in the study area.

This study aims to develop the trustworthiness model for public digital records, as an admissibility framework for establishing trust. The trustworthiness model is deemed to used to identify the qualities of the digital records in their lifecycle, including the identity that could be identified at the time of the creation, integrity obtained from the chain-of-custodial management, the evidence of relationship between business activities and records, and the technical or cognitive accessibility. Based on the analysis of the QADEP model, it was decided to develop a model that could measure the trustworthiness of public digital records in the external measurement type, which are authenticity, reliability, and usability. In line with this direction, the model expanded measurement areas and indicators of the QADEP model through the analysis of ISO 16175-1:2020, and measuring metrics was also proposed so that it could be a measuring instrument for public digital records in Korea, after analysing NAK 19-3. It would be useful to expand the model and to test the approach of the trustworthiness model for public digital records.

The purpose of this study is to suggest practical plans to improve the school library consulting, especially in case of a teacher librarian is not assigned. As a result of analyses, consulting through methods of the School Library Assistant Group lacks spontaneity, expertise, council, and independence. Besides, each office of education operates it as a marketing. A main goal of school consulting is to foster independent problem- solving of individual schools. Accordingly, it is necessary to build an union management system, develop a standard staff manual, construct DLS based on-line consulting, and design educational training programs of consultants for its successful consulting.

File integrity checking is the most reliable method to examine integrity and stability of system resources. It is required to examine the whole data whenever auditing system's integrity, and its process and result depends on administrator's experience and ability. Therefore the existing method is not appropriate to intrusion response and recovery systems, which require a fast response time. Moreover file integrity checking is able to collect information about the damaged resources, without information about the person who generated the action, which would be very useful for intrusion isolation. In this paper, we propose rtIntegrit, which combines system call auditing functions, it is called Syswatcher, with file integrity checking. The rtlntegrit can detect many activities on files or file system in real-time by combining with Syswatcher. The Syswatcher audit file I/O relative system call that is specified on configuration. And it can be easily cooperated with intrusion response and recovery systems since it generates assessment data in the standard IDMEF format.

물정보 중 가뭄 정보가 상대적으로 부족한 원인은 무엇을 가뭄으로 볼 것인지 정의하기 어렵기 때문이다. 특히 우리나라와 같이 댐 및 저수지, 광역상수도 등 수자원시스템 네트워크를 기반으로 물공급이 이루어지는 경우, 개별 요소만을 고려한 기존 가뭄모니터링 및 전망은 현실적이지 못하며, 가뭄 위험도 관리 측면에서도 부족한 부분이 있다. 가뭄 현상의 경우 기상학적 영향인 강수의 부족이 가장 큰 요소로 기여하지만 실질적으로 국민에 필요한 양보다 적은 양의 물이 공급될 때 국민들은 가뭄을 체감한다. 이러한 점을 보완하기 위하여 지역별로 사용하는 수원 및 물수급 시설 등을 세분화하고, 실적기반 분석을 통해 분석대상 지역의 가뭄을 정확히 판단하기 위한 합리적인 물수급 분석 모형 개발이 필요하다. 즉, 공간분석단위를 표준유역 단위 이하의 취방류 시설물을 기준으로 구성하고, 이들 시설물의 운영정보와 수문기상 빅데이터를 연계한 물순환 모형을 구현함으로써 댐, 저수지, 하천 등 다양한 수원을 가지는 유역 내 가용 수자원량을 준실시간 개념으로 평가하는 시스템의 개발이 필요하다. 본 연구에서는 하천을 중심으로 물수급 관련 수요·공급 시설의 위치를 절점으로 부여하고 연결하는 물수급 네트워크 알고리즘을 통해 빅데이터 기반 물수급 분석 모형을 개발하였다. 주요 모니터링 지점 및 모든 이수 시설의 위치를 유역분석 기법을 통하여 점(point), 선(line), 면(shape)으로 구성된 지형공간정보의 위상(topology) 관계를 설정하여 물수급 분석의 계산순서를 선정하고, 시계열 DB를 입력하여 지점별 물수급 분석 결과를 도출하였다. 권역별 주요 수위-유량관측소 1:1 Nash 계수를 검증한 결과 저유량에서 0.8 이상의 높은 재현 성능을 보이는 것으로 나타났다. 이에 따라 본 연구에서 개발된 물수급 분석 모형은 향후 물관련 이슈 지역의 용수공급능력 평가 및 수자원장기종합계획 등 다양한 수자원 정책평가에 활용될 것으로 기대된다.

최근 기후변화로 인해 기온, 강수량 등 농업에 직접적인 영향을 주는 환경요인의 변화가 급격하게 진행되고 있으며, 식량농업기구 (Food and Agriculture Organization of the United Nations, FAO)는 기후변화로 인해 전 세계적인 식량위기가 발생할 가능성이 크다고 경고하고 있다. 농업 시스템의 생산 능력을 확보하기 위해 수자원의 효율적인 공급 및 분배, 수확량 예측, 토지 특성 파악 등 농업 생산 제한요소에 대한 빠른 정보수집이 요구되고 있다. 재해관리 분야에서 원격탐사 기술은 재해 발생을 인지하고 발생지역의 재해 진행과 피해 정도를 신속하게 제공할 수 있다는 점에서 효용성이 높다. 또한 위성 영상을 이용할 경우 접근이 용이하지 못한 지역의 조사가 수월하며, 장기적인 변화관측이나 환경감시 등 광역적 접근이 가능하다. 최근 위성영상을 통한 다양한 신호의 데이터 취득 및 가공이 가능하게 됨에 따라 주기적이고 동일한 정확도로 지상자료의 획득이 가능하다는 측면에서 인공위성을 활용한 농업 분야에서의 가뭄 분석 연구의 필요성이 대두되었다. 위성영상 신호를 통해 농업 가뭄에 활용되고 있는 지표로는 정규식생지수 (Normalized Difference Vegetation Index, NDVI) 및 식생상태지수 (Vegetation Condition Index, VCI), 식생가뭄반응지수(Vegetation Drought Response Index, VegDRI) 등이 있다. 잠재 증발산과 실제 증발산의 비를 이용한 위성영상기반의 가뭄지수인 Evaporative Stress Index (ESI)는 일반적으로 사용되는 가뭄지수인 표준강수지수(Standardized Precipitation Index, SPI), 파머가뭄심도지수 (Palmer Drought Severity Index, PDSI) 등과 비교하였을 때, 가뭄에 더 민감하고 빠른 반응을 보인다는 연구 결과로부터 짧은 기간의 급속하게 발생하는(rapid-onset) Flash drought의 가뭄판단지표로 활용되고 있다. 본 연구에서는 과거 우리나라에 발생했던 극심한 가뭄 사상을 대상으로 ESI의 가뭄분석을 통해 타 지표와의 차별성을 확인하고 농업 가뭄 모니터링의 새로운 지표로써 적용성을 검토하고자 한다.
