The school library work support system was newly developed as 2024 Doksero DLS, but the DLS-compliant cataloging rules have not changed significantly since it was initially developed, and the current developed cataloging guidelines in 2020 also need to be updated. This study is to propose the considerations for developing guidelines for applying the DLS cataloging rules based on KCR4 by comparing the existing DLS (Ver. 2.0) cataloging rules, the 2024 DLS cataloging rules, and the 2020 bibliographic registration guidelines (Ver. 2.2). On this basis, considerations were suggested in terms of changing and expanding data elements, revising content rules for cataloging, method for recording access point, and developing controlled vocabularies. This study will allow to implement revision of DLS cataloging rules, development of guidelines, and system improvements.

This paper reports a meta-analysis of sixteen studies that evaluated the efficacy of cognitive behavioral therapy (CBT) for persistent primary insomnia. PubMed, Cochrane Library, EMBASE, CINAHL and several Korean databases were searched between January 2015 and June 2015. The main search strategy involved the terms that indicate CBT-I (Cognitive Behavioral Therapy-Insomnia) and presence of insomnia. Methodological quality was assessed using Cochrane's Risk of Bias. Data were analyzed by the RevMan 5.3 program of Cochrane Library. Sixteen clinical trials met the inclusion criteria, resulting in a total of 1503 participants. Stimulus control, sleep restriction, sleep hygiene education, and cognitive restructuring were the main treatment components. CBT-I was conducted for a mean of 5.4 weeks, 5.5 sessions, and an average of 90 minutes per session. The effects of CBT-i on total sleep time (d=-0.31), sleep onset latency (d=-0.29), awakening time after sleep onset (d=-0.55), sleep efficiency (d=-0.70), insomnia severity (d=-0.77) and sleep belief (d=-0.64) were significant. Overall, we found a range from small to moderate effect size. CBT-I also was effective for anxiety (d=-0.30) and depression (d=-0.35). The findings demonstrate that CBT-I interventions will lead to the improvement of both sleep quality and quantity in patients with insomnia.

A 69-group cross section library consisting of more than 130 materials was generated for thermal reactor applications using the NJOY nuclear data processing system and the recent version of evaluated nuclear data files available from IAEA Nuclear Data Section. The multigroup library was validated through the analysis of various criticality experiments and depletion results of PWR. When used with the WIMS-KAERI code, the average $K_{eff}$ obtained for 47 uranium-oxide and 41 uranium metal fueled critical configurations is 0.9997 with a standard deviation of 0.69 percent. The calculated burnup dependent isotopic inventories of uranium and plutonium generally show good agreement with measured values obtained from depleted PWR pins.s.

Introduction. Inadequate methods for acquiring user education could affect the level of library user education possessed by postgraduate students, and ultimately influence the purposes of their usage of e-resources provided in their university libraries. Despite the global acceptance that e-resources are contributing to postgraduate student’s research work, however, it has been documented that there is low use of e-resources in university libraries in Nigeria among postgraduate students. This drift could have negative consequences on their overall development. Therefore, this study determined how influential library user education is on the use of e-resources by postgraduate students in Nigerian university libraries.Methods. A survey research design and multi-stage sampling technique was adopted to select 2,726 from 54,578 postgraduate students from four faculties in 16 federal conventional universities in Nigeria. The data set was collected using a questionnaire and an interview schedule for e-resources librarians/system librarians and was analysed using percentage and Pearson’s product moment correlation.Results. The majority of the students were at the Master’s level (57.5%). The gender shows a ratio of 59.0% male and 41.0% female. Most Nigerian students enrol for postgraduate programmes in their thirties ‘30-39’ years. The use of e-resources by the postgraduates was low (weighted average of 2.45). The relationship between level of library user education and postgraduate students’ use of e-resources was positive, slightly strong, and significant (r = 318; df = 2284; p< .05).Conclusion. User education has positively inclined postgraduate students to the use of e-resources in their libraries. Therefore, libraries should employ all methods for acquiring user education for postgraduate students.

In this Paper, we present a non-doglegging channel routing system for If layout using standard cells. This system produces a final two-layer wiring pattern in the horizontal track between two rows, each of which is a linear placement of standard cells of identical heights, satisfying the given net list specification. The layout of CMOS cell library Including nine primitive cells used in this paper is represented in CIF (Caltech Intermediate Form) using λ(Lambda) of 2 microns in Mead-Conway layout representation scheme. The cell dimension and 1/0 characteristics such as name, position and layer type of the pins are stored in Component Library to be used in the channel routing progranl, CROUT. 4 subprogram, NET-PLOT, was used to report a schemdtic layout result, and another subprogram, NETCIF was used to with a full-fledged final layout representation in GIF, A test run for realizing a dynamicmaster-slave D flip-flop with set/reset using primitive cells was shown to take 4 CPU seconds on VAX 11/780.

Altmetrics or alternative metrics gauge the digital attention received by scientific outputs from the web, which is treated as a supplement to traditional citation metrics. In this study, we performed a meta-analysis of correlations between classic citation metrics and altmetrics indicators of library and information science (LIS) articles. We followed the systematic review method to select the articles and Erasmus Rotterdam Institute of Management Guidelines for reporting the meta-analysis results. To select the articles, keyword searches were conducted on Google Scholar, Scopus, and ResearchGate during the last week of November 2021. Eleven articles were assessed, and eight were subjected to meta-analysis following the inclusion and exclusion criteria. The findings reported negative and positive associations between citations and altmetric indicators among the selected articles, with varying correlation coefficient values from -.189 to 0.93. The result of the meta-analysis reported a pooled correlation coefficient of 0.47 (95% confidence interval, 0.339 to 0.586) for the articles. Sub-group analysis based on the citation source revealed that articles indexed on the Web of Science showed a higher pooled correlation coefficient (0.41) than articles indexed in Google Scholar (0.30). The study concluded that the pooled correlation between citation metrics with altmetric indicators was positive, ranging from low to moderate. The result of the study gives more insights to the scientometrics community to propose and use altmetric indicators as a proxy for traditional citation indicators for quick research impact evaluation of LIS articles.

Altmetrics is an alternative impact evaluation index that evaluates the social interest in the research performance of individuals or institutions in universities, research institutions, and research fund support institutions. This study empirically analyzed what kind of attention a papers of domestic library and information science researchers published in an international academic journal was receiving in the international community using Altmetric explorer. As a result of the analysis, 230 papers were tracked. The average Altmetric Attention Score (AAS) was 6.63, but there were 2 papers that received overwhelming attention (over 170 points) as they were mentioned in news report and Twitter. Second, there was a tendency for high AAS to appear in cases where a domestic researcher participated as a co-author and the main author belonged to an overseas institution, and in the case where the research funds were supported by foreign government agencies. In addition to the field of the library information science or information system, the papers classified as the field of public health service and education showed high AAS, and it was confirmed that these papers were published in the journals of various fields such as life science. Finally, it was confirmed that there was a weak correlation of r =0.25 between the AAS and the number of citations of the analyzed paper, but a strong correlation of r =0.68 between the number of Mendeley readers and the number of citations.

This study uses Gini coefficient to index the inequality of academic information resource among universities to identify the areas where the gap is extremely severe, and analyzes the Gini coefficient over time for 10 years to show how the gap is changing. In addition, the degree and characteristics of the gap appearing by type of universities such as metropolitan universities, local national universities, private universities, and colleges were also compared. As a result, first, the university library academic information infrastructure showed a severe level of disparity (0.6 - 0.9), and the inequality was more severe in serials, electronic resources, and reference service. Even when the relative Gini coefficient was calculated considering the number of students, the inequality was over 0.4 in serial etc. Second, the Gini coefficient trend over the last decade shows that the inequality has decreased toward equality in the re-education time of employees and electronic information resources, but not in other sectors. Third, it was found that special universities and universities in the metropolitan area showed a large gap between universities of the same kind, and local national universities showed the best gap level as well as the best academic information infrastructure.
