Recently, the use of NAND flash memory is being increased as a secondary device to displace conventional magnetic disk. NAND flash memory, as one among non-volatile memories, has many advantages such as low power, high reliability, low access latency, and so on. However, NAND flash memory has disadvantages such as erase-before-write, unbalanced operation speed, and limited P/E cycles, unlike conventional magnetic disk. To solve these problems, NAND flash memory mainly adopted FTL (Flash Translation Layer). In particular, garbage collection technique in FTL tried to improve the system lifetime. However, previous garbage collection techniques have a sensitive property of the system lifetime according to write pattern. To solve this problem, we propose BSGC (Balanced Selection-based Garbage Collection) technique. BSGC efficiently selects a victim block using all intervals from the past information to the current information. In this work, SFL (Search First linked List), as the proposed block allocation policy, prolongs the system lifetime additionally. In our experiments, SFL and BSGC prolonged the system lifetime about 12.85% on average and reduced page migrations about 22.12% on average. Moreover, SFL and BSGC reduced the average response time of 16.88% on average.

The aim of this study is to discuss ways to improve Korea's housing survey by comparatively analyzing the housing surveys being carried out in six other countries. The subject countries are the United States, the United Kingdom, France, the Netherlands, Australia, and Japan-the countries that conducts large-scale surveys for more than 20,000 households on a national level and where data collection is easily available. The comparative analysis items include survey history, purpose, subject, project owner, survey item, data collection method, and the use of survey outcome. The comparative analysis results showed that each of the six countries are conducting national housing condition surveys on a regular basis considering each nation's characteristics of housing stock and policy goals, and the survey results are being used as the basis for setting policy guidelines including the selection of policy targets and the determination of appropriate rent standards, and the basis for housing assistance budget planning. Korea's housing survey has been conducted three times up until now since 2006. There should be efforts to systemize and standardize the survey components, establish standards for monitoring the changing trend of national housing stock, standards for determining policy targets, and measures to open data and provide feedback considering the preceding studies of overseas countries in order to better utilize the housing survey data for policy development.

A common problem encountered in product or process design is the selection of optimal parameter levels which involves simultaneous consideration of multiple response variables. This is called a multiresponse problem. A multiresponse problem is solved through three major stages: data collection, model building, and optimization. Up to date, various methods have been proposed for the optimization, including the desirability function approach and loss function approach. In this paper, the existing studies in multiresponse optimization are reviewed and a future research direction is then proposed.

The purpose of this study is to activate the videorecordings in public libraries. The method of activation is to analysis of data which collected through questionnaire from respondent libraries. The results of the study are as follows : 1. The budget of videorecordings is absolutely short. 2 The acquisition policy of videorecordings is not planned because of short budget and little standard selection tool. 3. Most of public libraries wanted to exchange and use of videorecordings through interlibrary loan. 4. The subject of collected videorecordings was almost oriented to the education and motion pictures. 5. Specialized collection policy of public libraries in Pusan is not considered in videorecordings selection. 6. 87 percent of public libraries are not circulate videorecordings to the end-user. 7. Group watching planning of videorecordings in public libraries was done by monthly. 8. 70 percent of public libraries was not perform user reaction survey after watching. 9. 13 percent of public libraries has done the video tape recording of TV programming. 10. Most of public libraries had not a video to introduce themselves and user also had not a plan to create a video. 11. Most of public libraries recognized the copyright law but they wanted to reproduct the videorecordings for user with permission of authors.

Children's literature has a significant impact on children's intelligence and emotional development. The interest in children's literature is increasingly growing with the expectation of the award winning books and the educational values of children's books. Although the interest has brought about a quantitative increase in the domestic children's books, it has difficulty selecting high-quality children's books among various books. In such an environment, the Children's Literature Award will provide an authoritative source of choice, which will help guide the selection of quality books to those who want to read children's books. In addition to this trend, the library should check the status of winning works and incorporate them into new collection development policies. The purpose of this study is to present the direction of the library book development policy of the public library. For this purpose, 10 public libraries in Seoul, Korea were selected and analyzed quantitatively and qualitatively through the collection status of the children's literature winning books, loan status, turnover, Bonn's use Factor, and Trueswell's 80/20 rule. Based on the results of this analysis, we would like to suggest some issues to be reflected in library development policy of the future.

The purpose of this study is to present the theoretical basis and quantified objective standards for the establishment of collection management policy. The study results are summarized as follows. Most of the study books were in the form of periodicals as a steady seller. Most of the steady sellers were textbooks which published periodically. As a modern novel, a steady seller was able to confirm the phenomenon of dependence on a specific author. Bestsellers were investigated to be influenced by publishers and authors. Books of publishers that publish comics and children's textbooks had a significant correlation with the selection of bestsellers. The average number of recommended books borrowed per recommended book was 14,871. The average number of loans per book selected as a bestseller was 53,531. Based on the loan data, about 80-82% of all top-tier loans were covered by 90%, and about 27-29% of all top-ranked loans were covered by 50%. This shows that the Pareto Principle can be firmly applied to public library lending patterns. Loans in the field of literature accounted for 50.6% of the total loans. Among literature, Korean literature accounted for 51.3% of the total. The natural sciences were generating more loans with a relatively small pool of literature compared to other subject fields.

Background: The coronavirus disease 2019 pandemic has been challenging the healthcare service, i.e., the vitalization of the point of care accompanying self-testing in vitro diagnostic medical devices (IVDs). This study aims to suggest priority criteria to classify self-testing IVDs using the analytic hierarchy process technique. Methods: Two dimensions of the characteristics embedded in the IVDs and the diseases to be diagnosed with self-testing IVDs were parallelly considered and independently investigated. In addition, three expert panels consisting of laboratory medical doctors (n=11), clinicians (n=10), and citizens (n=11) who have an interest in the selection of self-testing IVDs were asked to answer to questionnaires. Priorities were derived and compared among each expert panel. Results: First of all, ease of specimen collection (0.241), urgency of the situation (0.224), and simplicity of device operation (0.214) were found to be the most important criteria in light of the functional characteristics of self-testing IVDs. Medical doctors valued the ease of specimen collection, but the citizen's panel valued self-management of the disease more. Second, considering the characteristics of the diseases, the priority criteria were shown in the order of prevalence of diseases (0.421), fatality of disease (0.378), and disease with stigma (0.201). Third, medical doctors responded that self-testing IVDs were more than twice as suitable for non-communicable diseases as compared to communicable diseases (0.688 vs. 0.312), but the citizen's group responded that self-testing IVDs were slightly more suitable for infectious diseases (0.511 vs. 0.489). Conclusion: Our findings suggested that self-testing IVDs could be primarily classified as the items for diagnosis of non-communicable diseases for the purpose of self-management with easy specimen collection and simple operation of devices, taking into account the urgency of the situation as well as prevalence and fatality of the disease.
