The improved DFSA for 2.4GHz multi-tags active RFID is suggested in 2 different ways: 1) simplified tag collection and Ack procedure using query command and 2) modified Schoute's method to control the number of slots in the frame. To evaluate the performance of the improved system we develop the simulation model. Varying the number of tags in the system we track the performance measures such as throughput, recognition time for multi-tags and tag recognition rate during a given time. The suggested method shows the best performance over all measures. Simplification of collection and Ack commands using query commands contributes to reducing tag recognition time. And the modified Schoute's method which controls the frame size using $k_1$ and $k_2$ contributes to throughput improvement and reduces target cognition time by reducing the number of collection rounds.

This study was dedicated to searching better course of low birth rate study in Korea by carefully analyzing past and present low birth rate researches. For this 179 studies(101 master thesis and 78 journal articles) from 1991 to 2009 were analyzed. Next, using SPSS Win 12.0, the research type, topic, participants, data collection and method of data analysis were compared to the studies' years of publication. The most frequently applied research approach, topic, sampling method, data collection procedure and data analysis method in the research was found to be a literature study, solution and prevention of low birth rate related policy, literature study, literacy analysis. In conclusion, low birth rate studies should become more diversified in terms of types of the research, data collection method, and data analysis. Additionally, research topics should become more realistic and specified. Moreover, research results should be verified before they are applied to the policy.

The purpose of this study is to improve the KESLI consortium by analyzing the status of participant organizations and their needs. A survey questionnaire including questions on consortium selection, management, and evaluation was distributed. The findings from the 179 responses indicate that the needs of the participants include issues related to the collection development policy, the cataloging of e-journals, user education, and evaluation. Therefore, KESLI should provide the following: (1) examples of collection development policy used for reference, (2) system development for e-journal cataloging, (3) materials and program guidelines for user education, and (4) education related to evaluation techniques for e-journal usages.

The purpose of this study is to bring out the most reasonable and feasible evaluation methods of research library collection in Korea. At the very outset, writer tried to define the purpose and the necessity of collection evaluation. Writer described a collection evaluation is to gain the data for decision making on selection policy, weeding and storage project, and explained it is one of the procedures of a collection development system operation of being explained as repeated three procedures through a collection development plan, an implimentation of the set plan(selection process) and a collection evaluation. Writer also pointed out the fact many libraries in Korea are apt to by pass or overlook this important process. Writer then defined the criteria of a collection evaluation as the measurement of the proportion of library holding's capability to meet users' demands and that of the degree of total collection's utilization. Writer introduced and analysed seven existing collection evaluation methods and concluded the method by a survey of users' needs and opinion and the method by a circulation survey are the most feasible and reasonable methods that can be applied. Writer also added that using above two evaluation methods together can enhance the effectiveness of collection evaluation.

This study aims to explore ways to improve self-censorship tendency in teacher librarians by identifying factors that influence the self-censorship which appears during collection development in elementary school libraries. For this purpose, first, we examined the concept of self-censorship through a review of related literature, then carried out a series of in-depth interviews as a pilot study to develop a questionnaire, which was used for a questionnaire survey. Finally, the survey data was analyzed statistically with SPSS 21.0, a statistical package. As a result, we have discovered statistically significant relationships between self-censorship and the characteristics in collection development policies, school library committees, and the complaints related with the library collections. Based on these results, the factors on the self-censorship were identified in the perception of the school librarians. Based on these results, we suggest to reinforce the function of review and approval of book selection in the school library committee, developed and approved a collection development policy include guidelines for dealing with users' complaints related to library collection, and stipulated a regulation for school library operation to remove inappropriate books from the library collection.

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.

The purpose of this study is to propose the importance of responding to the increasing issues related to collection management surrounding school libraries by analyzing the status of collection management policies (CMP) at the school libraries. Accordingly, through literature research, the main contents of the composition of the CMP for children and adolescent users were analyzed. Based on this, a 50 questions questionnaire was conducted and analyzed on the status of the CMP and the composition of the contents of the CMP for 93 school library managers nationwide. As a result, first, the data used as the selecting collections priority selection criteria were curriculum-related and recommended book lists rather than CMP. Second, 31 out of 93 school libraries (33.3%) had with CMP. Third, the understanding and necessity of the CMP of the school library manager with the CMP were higher. Fourth, it was found that more than half of the components of the CMP did not include the renewal cycle, intellectual freedom, etc.

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.

This study illustrates the process of the development of founding collection in public libraries. Specifically, this study surveys such cases of ten public libraries recently opened. It also analyzes current laws and standards about library collection and compares the criteria with the ones in various manuals and reports. For the study, supplementary data were also collected through qualitative interviews and brain-storming discussions with public librarians and other regional government officials who were in charge of the library construction project. For the suggestion to improve the quality of such founding collection, the researcher put the emphasis on the construction of collection development policy for the library, on the official collection plan, on the adequate volume of founding collection, and on the strategies for collection programs about regional studies.
