  • Rising publication costs and declining financial resources have resulted in renewed interest among librarians in resource sharing. Although the idea of sharing resources is not new, there is a sense of urgency not seen in the past. Driven by rising publication costs and static and often shrinking budgets, librarians are embracing resource sharing as an idea whose time may finally have come. Resource sharing in electronic environments is creating a shift in the concept of the library as a warehouse of print-based collection to the idea of the library as the point of access to need information. Much of the library's material will be delivered in electronic form, or printed. In this new paradigm libraries can not be expected to su n.0, pport research from their own collections. These changes, along with improved communications, computerization of administrative functions, fax and digital delivery of articles, advancement of data storage technologies, are improving the procedures and means for delivering needed information to library users. In short, for resource sharing to be truly effective and efficient, however, automation and data communication are essential. The possibility of using full-text online databases as a su n.0, pplement to interlibrary loan for document delivery is examined. At this point, this article presents possibility of using full-text online databases as a means to interlibrary loan for document delivery. The findings of the study can be summarized as follows : First, turn-around time and the cost of getting a hard copy of a journal article from online full-text databases was comparable to the other document delivery services. Second, the use of full-text online databases should be considered as a method for promoting interlibrary loan services, as it is more cost-effective and labour saving. Third, for full-text databases to work as a document delivery system the databases must contain as many periodicals as possible and be loaded on as many systems as possible. Forth, to contain many scholarly research journals on full-text databases, we need guidelines to cover electronic document delivery, electronic reserves. Fifth, to be a full full-text database, more advanced information technologies are really needed.

  • Linking Ukraine's education system with the trends of global digitalization is mandatory to ensure the sustainable, long-term development of the country, as well as to increase the sustainability of the education system and the economy as a whole during the crisis period. Now the main problems of the education system in Ukraine are manifested in a complex context caused by Russian armed aggression. In the context of war, problems include differences in adaptation to online learning among educational institutions, limited access to education for vulnerable groups in the zone of active hostilities, the lack of digital educational resources suitable for online learning, and the lack of basic digital skills and competencies among students and teachers necessary to properly conduct online classes. Some of the problems of online learning were solved in the pandemic, but in the context of war Ukrainian society needs a new vision of education and continuous efforts of all social structures in the public and private environment. In the context of war, concerted action is needed to keep education on track and restore it in active zones, adapting to the needs of a dynamic society and an increasingly digitized economy. Among the urgent needs of the education system are a change in the teaching-learning paradigm, which is based on content presentation, memorization, and reproduction, and the adoption of a new, hybrid educational model that will encourage the development of necessary skills and abilities for students and learners in a digitized society and enable citizens close to war zones to learn.

  • 온라인 데이터 스트림에 대한 부분 공간 클러스터링은 데이터 공간 차원의 모든 부분 집합을 검사해야 하므로 많은 양의 메모리 자원을 필요로 한다. 유한한 메모리 공간에서 데이터 스트림에 대한 클러스터들의 지속적인 변화를 추적하기 위해 본 논문에서는 메모리 자원을 효과적으로 사용하는 격자기반 부분 공간 클러스터링 알고리즘을 제안한다. n차원 데이터 스트림이 주어지면 각 차원 데이터 공간에 있는 데이터 항목의 분포 정보를 격자셀 리스트에 의해 모니터링 된다. 첫번째 레벨의 격자셀 목록에서 데이터 항목의 빈도가 높아 단위 격자셀이 되면 해당 격자셀로부터 모든 가능한 부분 공간의 클러스터를 찾기 위해 다음 레벨의 격자셀 리스트를 자식 노드로 생성한다. 이와 같이 최대 다차원 n레벨의 격자셀 부분 공간 트리가 구성되고, k차원의 부분 공간 클러스터는 부분 공간 격자셀 트리의 k레벨에서 찾을 수 있다. 실험을 통해서 제안하는 방법이 기존 방법만큼 정확도를 유지하면서, 밀집 공간만 확장하여 컴퓨팅 자원을 보다 효율적으로 사용하는 것을 확인하였다.

  • 본 논문은 마감시간을 가진 작업들의 온라인 스케줄링 문제를 다룬다. 작업들이 시간이 지남에 따라 도착하고 스케줄링 알고리즘은 앞으로 도착할 작업들의 정보를 미리 알지 못한다. 작업들은 동일한 수행시간만큼 실행되고 알고리즘의 목표는 마감 시간 안에 수행을 완료한 작업들의 수를 최대화하는 것이다. 온라인 알고리즘의 성능은 모든 작업 정보를 미리 알고 최적의 답을 줄 수 있는 최적 알고리즘의 성능과 비교하는데 두 알고리즘 성능의 비를 경쟁비라고 한다. 일반적으로 정보의 부재로 인해 온라인 알고리즘은 큰 경쟁비를 가진다. 따라서 온라인 알고리즘에 보다 많은 머신 또는 보다 빠른 머신을 제공했을 때의 경쟁비를 계산하는 자원추가 분석을 수행할 수 있다. 본 논문에서는 온라인 알고리즘이 보다 많은 머신들을 이용할 수 있을 때 최적 알고리즘과 같은 성능을 낼 수 있음을 보일 것이다.

  • This paper builds a system dynamics model analyzing first mover effect and growth strategy of online retailer, a major segment of B2C e-commerce. The dynamic model in this paper is calibrated to the online book market and Yes24.com as major test cases. The model consists of eight key value chain sectors. Five of these(Users, Site Operations, Human Resources, Financial Accounting, and Fundraising) are internal to the company, and three others(Market, Financial Market, and Relative Performance) are external to the company. With the model, this paper suggests research propositions representing positive feedback loops and negative feedback loops that lead to corporate growth and limits to growth according to dynamic causal relationships among eight key value chain sectors, and simulate these propositions.

  • Now more than ever, many journalists are using hospitals' homepages for articles about hospitals, their mission, research, and events. Therefore hospitals' homepages have to be planned and constructed for journalists. The purpose of this study is to investigate hospitals' online media relations through analysing homepages. For investigating specifically, this study compares hompages of hospitals in Korea and hospitals in USA. This study uses four categories; basic media relations tools, useful information, interactive communication tools, and ease of use for journalists. The result of this study shows that hospitals' homepages in Korea are needed to improve for building with journalists. The hospitals' hompages have to be constructed by a variety of materials; press room, image and graphic archives, multimedia resources, and interactivity or responsiveness. This study suggests that the hospitals' homepages have the potential to achieve the desired public relations objective but are not commonly being used to their full potential in media relations.
