This study determines 69 iSchools provided which data science curriculum, and presents the direction for Korean LIS schools. It is certain that iSchools extend their subject territory including areas related to health, technology and biotechnology. However, this phenomenon is not actively observed in Korea. iSchools also focus on the area about how to process and manage data. iSchools, in deed, offer courses regarding data science, data management and data security. The 'database' was a higher proportion of 'data warehouse' curriculum, and, 'data statistic and analysis' curriculum are forming similar portion. As a result of analysis of the iSchool's curriculum and comparison with Korean curriculum, this study suggests: the expansion of LIS curriculum related to data science; the enhanced role of the data translational data science; development of curriculum to raise the mathematical analysis capabilities, development of specialized curriculum and experimental classes; and support new knowledge skills to interact with technology.

The aim of this study was to discover various Library and Information Science (LIS) research areas by examining similarities and differences between LIS journals in terms of keyword characteristics. To conduct this study, for the years from 2004 to 2016, the keywords of 6 international journals were downloaded from Scopus database (http://www.scopus.com), and the keywords of 4 Korean journals were downloaded from the RISS database (http://www.riss.co.kr). The characteristics of keywords were investigated by examining frequently used keywords and frequently used distinctive keywords pertaining to international and Korean journals. The distinctive keywords are referred to as the keywords that appear in one domain but not in another. The result of this study indicated the following: a) a frequency analysis of the keywords showed major research themes and unique traits concerning Korea. b) In general, the keywords used in Korean journals frequently reflected the library as a major subject area of research, while keywords used in international journals reflected bibliometrics and information retrieval as major subject areas of research. c) The overarching themes of each created dataset were clearly noticeable in frequently used distinctive keywords. d) Some keywords were bound by a nation or by a region due to their scope of usage. The important implication of this study is that both most frequently used keywords and most frequently used distinctive keywords seemed to adequately represent the LIS subject areas.

Purpose : To evaluate the potential prognostic value of the antithrombin-III (AT-III) level in the children with acute lung injury (ALI), we analyzed several early predictive factors of death including AT-III level at the onset of ALI and compared the relative risk of them for mortality. Methods : Over a 18-month period, a total of 198 children were admitted to our pediatric intensive care unit and 21 mechanically ventilated patients met ALI criteria, as defined by American-European consensus conference, i.e., bilateral pulmonary infiltrates and $PaO_2/FiO_2$ lower than 300 without left atrial hypertension. Demographic variables, hemodynamic and respiratory parameters, underlying diseases, as well as Pediatric Risk of Mortality-III (PRISM-III) scores and Lung Injury Score (LIS) at admission were collected. AT-III levels were measured within 3 hours after admission. These variables were compared between survivors and non-survivors and entered into a multiple logistic regression analysis to evaluate their independent prognostic roles. Results : The overall mortality rate was 38.1% (8/21). Non-survivors showed lower age, lower lung compliance, higher PEEP, higher oxygenation index (OI), lower arterial pH, lower $PaO_2/FiO_2$, higher PRISM-III score and LIS, and lower AT-III level. PRISM-III score, LIS, OI and decreased AT-III level (less than 70%) were independently associated with a risk of death and the odds ratio of decreased AT-III level for mortality is 2.75 (95% confidence interval; 1.28-4.12) Conclusion : These results suggest that the decreased level of AT-III is an important prognostic factor in children with ALI and the replacement of AT-III may be considered as an early therapeutic trial.

The national coordinate system is an essential component for a geographic/land information system, since it provides the spatial reference for expressing position information. The national mapping of Korea has been based on 3-different meridians on the Gauss-Schreiber projection in year 1910s, later this was changed to the Gauss-Kruger projection. Existing map coordinate systems maintaining the national land survey project on 1910s, have some structural shortcomings of unknown computational procedures and projection methods. In this paper, the problems of the map coordinates usage and of longitudes origin shift(10.405") and their solutions are investigated. Also, this study discusses the issues involved in choosing coordinate system for digital mapping and their applications as a basis for spatial data management. The foreign country's coordinate systems are reviewed and the elements to realize a new unified grid coordinate system is proposed. The Transverse Mercator projection with a central meridian of $127^\circ\;30'$, scale factor 0.9996, and GRS80 ellipsoid, is selected in Korean peninsula.sula.

Background : The mortality from acute respiratory distress syndrome(ARDS) in the late stage, which is characterized by progressive pulmonary fibroproliferation, is ${\geq}80%$. Although previous prospective trials failed to show a survival benefit of steroid therapy in early ARDS, recently, a few of reports have described the survival benefit of the long-term use of steroid in patients with late ARDS. In this study, we analyzed the effect of steroid therapy on patients with late ARDS retrospectively in a single. Medral intensive care unit (MICU). Methods : Over a 3-year period, the medical records of 48 ARDS patients who had been on mechanical ventilation more than 8 days were reviewed. 14 patients were treated by the long-term use of methylprednisolone and another 34 patients served as a control. Both groups were comparable regarding clinical and physiologic data lung injury score(LIS), multiple organ failure score, APACHE III and SAPS II score. Because steroid was instituted after 8 days of advanced mechanical ventilatory support in average, we arbitrarily defined the $8^{th}$ day of ARDS as first day of the study. Results : Initially, the groups had similar PF($PaO_2/FiO_2$) ratio, LIS, APACHE III and SAPS II score. By 7th day after the start of steroid therapy, there were significant improvements in PF ratio, LIS, APACHE III and SAPS II score. The mortality in the steroid treated group was significantly lower(42.9% vs 73.5%, p<0.05). Conclusion : Although the data of this study was retrospective and was not randomized, in order to improve the patient's outcomes, steroid therapy should be considered in late ARDS patients. However, prospective trials are needed to define the indication and the effect of steroid therapy in late ARDS.

Librarian certification in Korea is issued by the LIS Departments, the Academy of Librarianship, and the Academic Credit Bank system; however, it has been pointed out that there is a limit to how much these nurture high quality librarians, because the education quality and contents varies from education institutions and there is no verification method for certification issued by educational programs. Therefore, this study investigated certification systems of academic or training programs that are conducted at home and abroad, analyzed how the certification systems are oriented, what the purpose and criteria of the certification systems are, and what the content of assessment is. As a result of this investigation, several areas needing change were identified which if adopted can improve the system. These included making amendments to the library laws related to the certification system, substantially revising the relevant enforcement ordinance, making changes to the selection of the Certification authority, establishing certification standards and procedures, developing contents related to document examination and due diligence audits, rating the effects of the certification system, and setting standards. Improving the Librarian Certification System has been discussed over the past 20 years and should not be delayed any longer because of the university structural reform of the current government, the rapid rise of the qualified librarians, decreasing employment due to the human resources supply and demand imbalances, all of which has resulted in a survival crisis of four-year Department of Library and Information Science.

Effective assessment of faculty research performance should involve considerations of both quality and quantity of faculty research. This study analyzed methods for evaluating faculty research output by comparing the rankings of Library and Information Science(LIS) faculty by publication counts, citation counts, and research performance assessment guidelines employed by Korean universities. The study results indicated that faculty rankings based on publication counts to be significantly different from those based on citation counts. Additionally, faculty rankings measured by university guidelines showed bigger correlations with rankings based on publication counts than rankings by citation counts, while differences in universities guidelines did not significantly affect the faculty rankings. The study findings suggest the need for bibliometric indicators that reflect the quality as well as the quantity of research output.

This study investigates the influence of project-based learning method on the problem-solving ability and communication ability of students taking the 'Reading Guide' course in Library and Information Science(LIS). During this study, two tests measuring students' problem-solving ability and communication ability were conducted, containing 30 items divided into 5 steps of problem-solving processes and 45 items divided into 15 categories of communication ability, respectively. By utilizing the correspondence sample T-test during this study, significant differences were found in the 5 steps problem-solving processes. However, no difference was found between the pre-test and the post-test results in all 15 categories of communication ability. Subsequently, an in-depth interview was conducted, inquiring into the students' perspectives on the difficulty of attending classes, the content of lectures, the appropriateness of assignments, the validity of the evaluation method, the relationship with their team members, and the benefits acquired from completing the projects. Finally, an intensive analysis was conducted in the categories of problem-solving ability and communication ability.

Background : The mortality from acute respiratory distress syndrome(ARDS) is >40-50%. Although some prospective trials have failed to demonstrate a survival benefit of steroids in the early stages of ARDS, there are some reports showing some success with steroids in the later stages. This study observed the changes in the physiologic parameters with time in late ARDS patients who were treated with steroids. Methods : The medical charts of 28 intensive care unit patients(male:female=24:4; mean age 64 years), who had been diagnosed with refractory late ARDS ($PaO_2/FIO_2$ <200) and were treated with corticosteroids from December 1999 to July 2002, were retrospectively reviewed. The patients were divided into two groups: the weaned group(n=14), which included the patients who had been successfully weaned from a ventilator after corticosteroid therapy, and the failed group(n=14), which included the patients who had failed weaning. The physiologic parameters included the $PaO_2/FIO_2$ ratio, the positive end-expiratory pressure(PEEP) level, the $PaCO_2$, compliance, the sequential organ failure assessment(SOFA) score, the acute physiologic and the chronic health evaluation(APACHE) II score, and the Murray Lung Injury Score(LIS) in the two groups were compared from the day of mechanical ventilation(Dmv) to 7 days after the corticosteroid therapy. Results : There was no significant difference in the clinical characteristics and the physiologic parameters between the two groups prior to the corticosteroid therapy except for the SOFA score at Dmv(weaned group : $6.6{\pm}2.5$ vs failed group : $8.8{\pm}2.9$, p=0.047). However, within 7 days after corticosteroid therapy, there was significant improvement in the $PaO_2/FIO_2$ ratio, the PEEP level, the $PaCO_2$, the SOFA score, the APACHE II score, and the LIS of the weaned group compared to the failed group. Conclusions : During corticosteroid therapy in late ARDS, the continuation of corticosteroid therapy should be determined carefully in patients who do not show improvement in their physiologic parameters by day 7.

This study is to objectively deduce components of a public library culture and define a library culture. Thus, the study gathers the opinions and the experiences of the expertise in this specific area of a library culture. Furthermore, the study takes gathered informations and dates into consideration, to derive a measurement of final components, delphi technique. Through usage of Delphi technique, it allowed selected final components to operate a comparative analysis of the elements, which then it helps to measure each element's critical importance, identify priorities of each element by using a hierarchical decision making method. The major conclusions of this study are as follows. First, the study used a two-step delphi survey which was conducted on a panel of experts (Faculty of Library and Information Science (LIS) and the librarians), deduced the components of a library culture. In the primary survey, the study found 29 components (material culture 6, non-material culture 23). In the secondary survey, it deduced 21 components (material culture 3, non-material culture 18). Second, through comparative analysis, the prioritization of the public library culture components presented in following orders, , , and . The Most weighted values of each components were, of 'data usage and its method.'; of 'core values of librarianship'; of 'library ethical consciousness.' appeared as such.
