In this paper, we propose a performance isolation of shared space for virtualized SSD based storage systems, to solve the weakness in a VSSD framework. The proposed scheme adopts a CFQ scheduler and a shared space-based FTL for the fairness and the performance isolation for multiple users on virtualized SSD based storage systems. Using the CFQ scheduler, we ensure SLOs for the storage systems such as a service time, a allocated space, and a IO latency for users on the virtualized storage systems. In addition, to improve a throughput and reduce a computational latency for garbage collection, a shared space-based FTL is adopted to maintain the information of SLOs for users and it manages shared spaces among the users. In our experiments, the proposal improved the throughput of garbage collection by 7.11%, on average, and reduced the computational latency for garbage collection by 9.63% on average, compared to the previous work.

Many IoT devices like sensors lack screen and input devices, thus making them hard to meet the consent conditions that GDPR requires. This is acting as a legal barrier for further advancement in the business field. In this paper, we designed the process for consent of personal information collection that meets the legal conditions. In this design, user's personal data is received in an encrypted form by data collecting server first. The encrypted personal data can be decrypted after associating with user agent based on the consent procedure of the collection of personal information. During the consent procedure, user agent understands the privacy policy about personal information collection and offers the key to decrypt the data. This kind of personal information collection agreement procedure will satisfy the transparent and freely given consent requirements of GDPR. Thus, we can speculate from here that the proposed procedure will contribute to the evolution of IoT business area dealing with personal information.

The purposes of this study were to define the current status of information infrastructures and electronic information retrieval systems in university libraries in Korea, to assess the impact of information technology on library collection development in Korea universities, and to determine the relationship between electronic information retrieval service and library collection development. Data was collected by a mail survey. Questionnaires were mail in December, 1997 to all 134 4-year university libraries. Approximately 78 percent of the questionnaires was returned. The data taken from the survey instruments were analyzed with the analysis of variance(ANOVA) test of SAS program.

The present survey aimed at analyzing factors influencing the development of the university library collection, with the special reference to the case of the Education Collection of the Pusan National University Library. For this, the present researchers have identified two areas of influencing factors, i.e.., library factors and user factors. Library factors included collection development policy, manpower, materials received as gift and budget. User factors included faculty and students. For analyzing the factors, the present researchers have relied on qualitative research techniques, using heavily documents produced within the case library, interviews librarians, faculty and students, and observation.

Green building information used by the AEC industry is diverse and extensive), causing difficulties for personnel regarding the collection and utilization of information in the form of inaccurate searches about related laws, inefficient management of searched information and overlapping works. Therefore, this research aims to propose a law search system utilizing metadata for more accurate and efficient searches of green building information. The proposed system is expected to contribute to improve productivity of construction projects by reinforcing the accuracy and efficiency of searches for the collection and utilization of green building information.

Korea's information dependency on the foreign information is high and the domestic information production volume absolutely insufficient. So, research and academic library will select information resources through the limited budget and back up the research and development. This paper propose methods using union cataloging for effective journal collection development through a case study on the OCLC Collection Analysis system and Ulrich Serials Analysis System(USAS).

Introduces and analyzes basic library collection management issues regarding electronic journals, including selection, budgeting, policy making, collection evaluation, and preservation/archiving. Argues that staffing and budgeting for electronic journals can be organized on subject-based or format-based approaches, or some combination of both. Electronic journals are selected through the same three-stage process used for print journals : identification, evaluation, and selection. Most of the traditional criteria for print journals are also applicable to electronic journals, but additional criteria are superimposed on them. The cancellation and weeding of electronic journals have not been addressed ;by ;the profession, but will assume more significance in the future. There is a need for new client-centered evaluation methodologies that focus on availability and accessibility rather than ownership.

Since the beginning of discussions on serial collection management, as budgets have waxed and waned over the ensuing decades, a number of key variables affecting selection/deselection have emerged but without the framework of a coherent and accepted theoretical model. This study is an effort to identify variables which affect the serial collection decision with special attention to selection/deselection in the context of an academic health science library. Based on results from correlation analyses and logistic regression analyses, the serial collection decision can be explained and predicted using various combinations of a reduced set of objective variables. Applications of the results to libraries are discussed, and further research is proposed.

The study aims at identifying professional competencies of collection development librarians in academic libraries. For this, the study collected data through qualitative interviews with 8 librarians who are in charge of collection development programs in four-year university libraries. As a result, the professional competency components emerging from interviews were divided into three parts; knowledge in library and information science, knowledge in subject field, and professionalism. Detailed components of three parts of professional competency were divided into 13 sub-categories, with 37 meanings. It is expected that the study as an exploratory research may provide further research to design educational and training programs for collection development librarians with basic data.

Data collection system is now widely used. This system is divided by embedded system and communication module. And data collection system in the remote area is using Satellite communication. So, data collection system is complicated and expensive. This paper proposes stabilization and cheapness of remote data collection system in dusty. The system can be composed simply through third party Satellite Communication programming of terminal including embedded system. Finally, collected data is transmitted to multi-user through web agent.
