  • Web accessibility refers to the practice of providing equal access to web sites to people without and with disability. This study aims to investigate the web content accessibility of 153 university libraries in Korea, and further suggest the approach to implement an effective university library web site to meet Korean Web Content Accessibility Guidelines(KWCAG). Survey was conducted with two steps. The first step was to find out the general level of web accessibility of all university library web sites using an automatic appraisal tool, KADO-WAH2.0, and the detailed examination of web accessibility check items was limited to 19 web sites which proved excellent in automatic appraisal. Regretfully, the result says that there is no perfect web site. Therefore every university library is advisable to make good use of the findings to meet all the requirements of KWCAG. In particular, the basic requirements, such as voice service, resizing and highlighting text, must be fulfilled by priority and to almost all contents.

  • The main purpose of the school library is to present the various kinds of instructional media for an effective instruction including not only books, but also audiovisual materials and equipments. But unfortunately our school libraries have only books for the students and faculties at this time. But hereafter school library should house the various kinds of audiovisual media as well as printed media for the promotion of scholarstic achivemint. With a view to promoting the teaching method, and at the same time improving the scholarstic achivement of the students, instructional media were used in the class. To verify the efficiency of the instructional media, transparencies were used in the social science class of the 1st grade in the middle school and the natural science class of the 1st grade in the high school. In consequence, the academic achievement of the experimental class in which instructional media were used is superior to that of controlled class in which the textbook was only used. In < Social Science I >, the mean difference between the experimental class and the controlled class is 4.199 marks. And the difference, 0.032 is verified as a significant value in concordance to the t-test. In < Natural Science I >, the mean difference of the experimental class over the controlled class is 6.333. And the difference, 0.034 is verified as a significant value in concordance to the t-test. As shown in the above experimental research, using various kinds of the instructional media is more efficient than using textbook only. As a result of the questionaire on using the instructional media, most of the students desire to use of them continually because the use of the instructional media induce the interest, promote the comprehension, and entice the development of better memories.

  • Purpose : This study aimed to systematically review the preventive interventions for delirium in Korean intensive care unit (ICU) patients and evaluate their efficacy. Methods : For this systematic review and meta-analysis, we searched the literature and selected studies from data sources that included the RISS, KISS, National Central Library, National Assembly Library, DBpia, Science on, MEDLINE, and Cochrane Library. We used Cochrane's revised tool for risk of bias in randomized trials and non-randomized studies of intervention tools to assess the quality of the selected studies. The effect size of the intervention was calculated as odds ratio (OR) and standardized mean difference (SMD). Results : Preventive interventions reported in 23 studies with a total of 4,799 ICU patients were effective in reducing the occurrence of delirium (OR=0.64, 95% CI : 0.49~0.91, p=.011), but not the duration (SMD=-0.22, 95% CI : -0.51~0.08, p=.148). As a result of a subgroup analysis, non-pharmacological interventions were effective in reducing the occurrence of delirium (OR=0.66, 95% CI : 0.47~0.94, p=.020), while pharmacological interventions had no effect (OR=0.68, 95% CI : 0.33~1.40, p=.295). Among the non-pharmacological interventions, multi-component intervention had the largest effect size (OR=0.38, 95% CI : 0.26~0.55, p<.001). Conclusion : Non-pharmacological interventions were effective in reducing the occurrence of delirium. We recommend the development and application of multi-component interventions to prevent delirium in the Korean ICU patients.

  • This study was conducted to analyze the characteristics of records related to Korea shown in the cataloging records of national libraries of the main 12 developing countries in Europe and South America. The results are as follows. To begin with, Korea-related records in most national libraries are very poor and under 0.01% of the library. Second, Korean materials usually write Korean in Roman characters except for National Library of Armenia, but there are not marked with the original Korean language and unfeasible Hangeul search. Third, on investigation of the subject distribution in sub criteria of Korea-related records, subject related to history, politics, and economy is largely shown in the highest rate. Fifth, among the Korea-related subject heading, Taekwondo is marked with distinction from Karate in most libraries except for National Library of Argentina. Dokdo is marked with the geographical name of 'Korea' in 8 national libraries and East Sea (Donghae) already is marked with 'Sea of Japan' in 7 national libraries. Amnokgang, Dumangang, and Baekdusan-related records did not search at all in most national libraries.

  • The dual-vector system-II (DVS-II), which allows efficient display of Fab antibodies on phage, has been reported previously, but its practical applicability in a phage-displayed antibody library has not been verified. To resolve this issue, we created two small combinatorial human Fab antibody libraries using the DVS-II, and isolation of target-specific antibodies was attempted. Biopanning of one antibody library, termed DVFAB-1L library, which has a $1.3{\times}10^7$ combinatorial antibody complexity, against fluorescein-BSA resulted in successful isolation of human Fab clones specific for the antigen despite the presence of only a single light chain in the library. By using the unique feature of the DVS-II, an antibody library of a larger size, named DVFAB-131L, which has a $1.5{\times}10^9$ combinatorial antibody complexity, was also generated in a rapid manner by combining $1.3{\times}10^7$ heavy chains and 131 light chains and more diverse anti-fluorescein-BSA Fab antibody clones were successfully obtained. Our results demonstrate that the DVS-II can be applied readily in creating phage-displayed antibody libraries with much less effort, and target-specific antibody clones can be isolated reliably via light chain promiscuity of antibody molecules.

  • This study was conducted to analyze the characteristics of records related to Korea shown in the cataloging records of national libraries of the main 10 developing countries in Asia and Africa. The results are as follows. To begin with, Korea-related records in most national libraries are very poor and under 0.1% of the library. Except for National Library of Viet Nam, the figure is under 3,000 volumes and generally 2 times less than Japan related records. Second, except for National Library of Iran and Viet Nam most national libraries romanize Korean materials, there are not marked with the original Korean language and unfeasible Hangeul search. Third, on investigation of the subject distribution in sub criteria of Korea-related records, subject related to history and economy is largely shown in the highest rate. Fifth, among the Korea-related subject heading, Taekwondo is marked with distinction from Karate in most libraries except for 7 national libraries. Dokdo is marked with the geographical name of 'Korea' in 7 national libraries and East Sea (Donghae) already is marked with 'Japan, Sea of' in 7 national libraries.

  • To validate the new Evaluated Nuclear Data File $(ENDF)/B-VIII.0{\beta}4$ library, 31 different critical cores were selected and used for a benchmark test of the important parameter keff. The four utilized libraries are processed using Nuclear Data Processing Code (NJOY2016). The results obtained with the $ENDF/B-VIII.0{\beta}4$ library were compared against those calculated with ENDF/B-VI.8, ENDF/B-VII.0, and ENDF/B-VII.1 libraries using the Monte Carlo N-Particle (MCNP(X)) code. All the MCNP(X) calculations of keff values with these four libraries were compared with the experimentally measured results, which are available in the International Critically Safety Benchmark Evaluation Project. The obtained results are discussed and analyzed in this paper.
