The purpose of this study is to suggest the components of manuscript collection development policy for Korean literary museums through literature review and the comparative analysis of the components of manuscript collection development policies of internal and external literary museums. As the examples of internal literary museums, the private rules of material selection of World Women's Literature Center and collection development policy of National Library of Korea have been studied. As the examples of external literary museums, 14 original collection development policies from British and American literary museums have been analyzed. According to the study results, the 11 basic elements and 14 selective elements were proposed for the manuscript collection development policy of Korean literary museums.

In this paper, we propose an efficient tag sleep method utilizing empty time slots for improving the tag collection performance in active RFID systems. In the proposed tag sleep method, the reader detects the occurrence of empty time slots by carrier sensing and utilizes the wasted empty time slots to transmit sleep commands to the collected tags throughout the framed slotted aloha-based tag collection process, resulting in reducing the time required for tag collection. Via the simulation experiments, we evaluated the performance of the tag collection applied with the proposed tag sleep method, compared with that of the basic tag collection. The simulation results showed that the tag collection applied with the proposed tag sleep method could reduce the average tag collection time by 12.28%, 12.30%, and 13.31 %, for the framed slotted aloha with the fixed 128 time slots and 256 time slots, and the dynamic framed slotted aloha anticollision protocols, respectively.

The study proposed a system that filters the data that is entered when analyzing big data such as SNS and BLOG. Personal information includes impersonal personal information, but there is also personal information that distinguishes it from personal information, such as religious institution, personal feelings, thoughts, or beliefs. Define these personally identifiable information as sensitive information. In order to prevent this, Article 23 of the Privacy Act has clauses on the collection and utilization of the information. The proposed system structure is divided into two stages, including Big Data Processing Processes and Sensitive Information Filtering Processes, and Big Data processing is analyzed and applied in Big Data collection in four stages. Big Data Processing Processes include data collection and storage, vocabulary analysis and parsing and semantics. Sensitive Information Filtering Processes includes sensitive information questionnaires, establishing sensitive information DB, qualifying information, filtering sensitive information, and reliability analysis. As a result, the number of Big Data performed in the experiment was carried out at 84.13%, until 7553 of 8978 was produced to create the Ontology Generation. There is considerable significan ce to the point that Performing a sensitive information cut phase was carried out by 98%.

The purpose of this study is to examine 5 writing guidelines of reference collection development policy(RCDP) and to identify major elements of RCDP through the comparison and analysis of 24 RCDP in academic libraries in the U.S. As a result of this study, a total of 9 elements(5 core elements and 4 selective elements) were identified. Five core elements were (1) introduction, (2) scope, size, and level, (3) format, (4) types, and (5) management(i.e., selection, weeding, evaluation, and responsibilities) of reference collection. The results of this study would be helpful to those academic libraries which are planning to write RCDP in academic libraries in the near future.

There are many techniques for locating users in an indoor spot. Among them, WiFi fingerprinting technique which is widely used is phased into a data collection step and a positioning step. In the data collection step, all surrounding Wi-Fi signals are collected and managed as a list. The more data collected, the better the accuracy of the indoor position based on Wi-Fi fingerprint. Existing high-quality data collection and management methods are time consuming and costly, and many operations are required to extract and generate data necessary for machine learning. Therefore, we research how to collect and manage large amount of data in limited resources. This paper presents efficient data collection methods and data generation for learning.

A collection development policy is the library's master plan that provides library's long/short-term plans. It also informs the community of the library's commitment in collection development. However, in Korea, libraries which maintain such a policy are not yet to be easily found. Furthermore, due to increasing importance of electronic resources, libraries are gradually required to have electronic resource management policy that reflects a change in the information environment. The purpose of this study is to suggest a model electronic resource management policy in academic libraries. It derived and verified more than thirty preliminary elements from literature and case studies. The elements were modified and supplemented, and as a result, the selection criteria gained the highest marks. The findings can be applied for selecting the elements of digital collection development policy in the university library and reorganizing them so as to meet its peculiarities. This study, finally, presents a model that includes a guideline for the university library which will establish digital collection development policy.

The purpose of this study is to develop an evaluation indicator of institutional repositories to be used by participating university libraries of dCollection. Based on the literature reviews of digital library evaluation, core evaluation measures and criteria were identified. In order to verify the applicability and appropriateness of those evaluation criteria for institutional repositories, two methods were employed: A case study with sixteen university libraries and a Delphi study with twenty university libraries. The results of both studies led the development of an evaluation model which consisted of four evaluation dimensions and 29 criteria. This evaluation model should be utilized as tools for objective assessment and guidelines for improving institutional repository services by universities libraries in which the dCollection is currently Implemented or the future plan of the dCollection is underway.

For this article, we conducted frequency analysis, topic modeling, and network analysis on eleven texts related to collection development policy found in the National Library of Korea. We deduced the main keywords related to collection development policies and analyzed the relationship between them. We subsequently conducted a pie coefficient analysis to identify the characteristics of collection development policies of university libraries and public libraries by category. The results showed that keywords such as "material," "library," "collection development," "user," and "collection" were the main keywords in frequency analysis and network centrality. Meanwhile, the pie coefficient analysis revealed that keywords such as "university," "construction," "student," "target," and "cost" were prevalent in university libraries, indicating that the academic needs of users and the discussion of digital resources were primary issues, while keywords related to the information needs of various user groups-including "adults," "survey," "feature," and "religion" -appeared in public libraries.

It has been known that test collections play an important role for researches in information retrieval. A variety of test collections have been created in foreign countries, and have been heavily used by researchers. Although research interests in Hangul information retrieval have been rapidly grown up in Korea these days, lack of Hangul test collec tions makes it difficult to develop retrieval techniques for Hangul texts. This study describes the development of the KRIST test collection. The KRIST test collection consists of 13.515 bibliographic records. 30 queries and a list of relevant documents to the queries.

The interest in the access and integration of distributed massive data resources has increased recently. This paper presents the Advanced Collection Manager(CM) service with OGSA-DAI component which can access and integrate the distributed data resources. The Advanced CM service supports the data resource of various types. And it can provide the query, updating, transforming and delivering data via cooperating with other services in Grid Information Retrieval(Grid-IR or GIR) System. As a result, it can access and manage the data resource more flexible and efficient.
