The rapid growth of information technologies and data networks has increased the volume of data generated from scholarly research and the possibilities of re-using and sharing such data. However, there is a serious problem of management and sharing of research data due to the lack of facilitating policies and supporting infrastructure. In particular, few data repositories exist that support systematic collection and sharing of research data in the humanities. In this regard, the Korea Research Memory (KRM) established by the Korea Research Foundation is a rare exception. The purpose of this research is to present specific processes and strategies that can facilitate the data collection, reuse and preservation through the KRM using task analysis and source document gathering as main focal points. In addition, in order for the effective collection and sharing of research data, the following recommendations are proposed: 1) the need for the adoption of data management plan related policies that govern the collection and sharing of research data generated from publicly funded research projects, 2) the need for training and support services for individual researchers and research institutes, 3) the need for training data specialists, and 4) the citation scheme and structure designed for research data.

로그 분석 솔루션의 필요성이 대두되어 공공기관 뿐만 아니라 사기업들도 앞다퉈 로그 분석 솔루션을 도입하여 보안관제센터를 구축하는 추세이다. 하지만 그 비용자체가 만만치 않아 아직까지 예산이 부족한 기관 및 기업은 도입하지 못하고 있다. 본 연구에서는 오픈소스를 활용하여 보안관제센터를 구축하는 방안을 제시하였다. ELK Stack을 이용하여 로그 분석 시스템을 구축하였다. ELK Stack의 검색 속도 및 로그 데이터의 시각화 성능은 시장 점유율 1위인 Splunk와 비교 했을 때 비슷하였다. 또한, 오픈소스를 이용하기 때문에 기업간 기술 공유를 통해 보안관제의 탐지기술이 한층더 업그레이드 될 수 있다.

Recently, the distributed system is being evolved into a new paradigm, named cloud computing, which provides users with efficient computing resources and services from data centers. Cloud computing would reduce the potential danger of Grid computing which utilizes resource sharing by constructing centralized data center. In this paper, a new data replication scheme is proposed for Hadoop distributed file system by changing 1:1 data transmission to 1:N. The proposed scheme considerably reduced the data transmission delay comparing to the current mechanism.

In this study, deals with selection of monitoring objects to handle emergency cases of multi-modal transfer stations and information required for emergency surveillance, recognition, verification, propagation, processing and situation closing. Furthermore, this article suggests integrated management scheme for the above information and methods which offer appropriate information required for situation handling decisions at each stage of situation changes. The transfer station which consists of facilities, passengers, and transportations has limitations in required monitoring information. So, for the situation recognition and handling strategy, case-based reasoning of the expert system was used to apply experience, knowledge, and past cases of situation handling experts. The article also suggests methods to control facilities which are operated at transfer stations and these methods can minimize spatial confusions and damages at the emergency situation. The real time situation information will be shared by proper facility controls to support services from external institutions.

The purpose of this study was to examine various factors influencing the needs of Seoul's newly implemented outreach community services for older adults, and to suggest the direction of the outreach community health services in Seoul. A multi-level regression was conducted using data collected by face-to-face interviews from 1,000 individuals aged 65 and 70 in 17 districts, where participated in the Seoul's outreach community services. The results demonstrated that socioeconomic status (higher income and living alone), health status (having multiple chronic conditions and depression, lower health literacy), limited experience of the outreach community services, and low government trust at the individual level were associated with higher unmet need for the community outreach services. In addition, shorter participation period of the outreach services and financial independency at the district level were associated with higher unmet need for the services. The findings from this study implies the need for improving the quality of services by focusing on vulnerable groups such as individuals with lower income and worse health status. In addition, the outreach community health services may need to target individuals aged 66 to increasing efficiency of the services through utilizing results of life-cycle health checkup by the National Health Insurance Corporation.

This study was intended to present the need for building the library as a hub of the community memory preservation which provides the collection, sharing, and curation services of the locality specific historical and local data based on the policy task, namely supporting the collection, preservation, and management system of the community's life memory. To this end, the current status of data collection, management, and operation of institutions serving regional-based materials such as cultural centers and regional archives was grasped, and the cases and status of curation services in libraries were investigated and analyzed. The discussion proposed via the results of the study are as follows. First, to the culture center, external demand has been increased from the aspect of social education including festivals, cultural and art event, cultural and art educational business, art activities business of local residents and managerial business is to be carried out, which makes it difficult for the culture center to manage its businesses. Accordingly, it is necessary to collect and preserve regional various data at the pubic libraries playing various roles including provision of informative services, cultural programs and information sharing places to local residents and provision of services to vulnerable social group. As the existing libraries have a plan to collect data systematically, it is considered that those libraries will smoothly operate the data management through cooperation with existing culture centers and various cultural organizations. Second, it appears that a plan will be needed to set up all the data including the ones owned by libraries, local administrative agencies, individuals and other competent agencies in online database so that they are easily available to the public and always available in the libraries because there are a lot of data which cannot be moved to other place and it is actually difficult to concentrate and set up all the data to those libraries.

최근 분산된 자원을 효과적으로 공유할 수 있는 그리드 기반의 과학 연구가 다양하게 진행되고 있으며, 그러한 예로 국내에서는 건설 및 토목 분야의 원격실험 관측과 제어를 포함한 공동연구 환경의 구축을 내용으로 하는 KOCED(Korea Construction Engineering Development) 프로젝트가 진행 중에 있다. 본 논문에서는 KOCED에서 구축 중인 실험센터의 하나로써, 지리적으로 떨어진 실험 시설과 수치시뮬레이션을 연동하여 실험할 수 있는 하이브리드 실험센터를 대상으로 데이터 모델링을 하였다. 데이터 모델은 데이터를 표현하는 용어를 통일하고 데이터 간의 관계를 명확하게 하여, 데이터의 재사용성을 높일 수 있기 때문에 실험비용이 많이 소모되는 과학실험에 필수적이다. 그리드에 기반한 하이브리드 실험의 데이터 모델링은, 기존의 건설 및 토목실험의 대부분이 독립적인 실험 형태였기 때문에, 정확한 데이터 모델을 예측하기가 용이하지 않았다. 따라서 먼저 하이브리드 실험의 축소 모형인, 프로토타입 실험체를 만들고, 이에 대한 데이터 모델을 설계하여 토목공학 연구자에 의해 사용하게 하였다. 일정기간 사용기간을 갖고, 이에 대한 회의를 통해 향후 구축될 하이브리드 실험센터의 데이터 모델을 설계하였다. 현재 하이브리드 실험의 데이터 모델을 그리드 포탈 기반의 데이터관리 서비스로 구현 중에 있다.
