The objectives of this study is to present a discovering process of interdisciplinary convergence technology using text mining of big data. For the convergence research of biotechnology(BT) and information communications technology (ICT), the following processes were performed. (1) Collecting sufficient meta data of research articles based on BT terminology list. (2) Generating intellectual structure of emerging technologies by using a Pathfinder network scaling algorithm. (3) Analyzing contents with topic modeling. Next three steps were also used to derive items of BT-ICT convergence technology. (4) Expanding BT terminology list into superior concepts of technology to obtain ICT-related information from BT. (5) Automatically collecting meta data of research articles of two fields by using OpenAPI service. (6) Analyzing contents of BT-ICT topic models. Our study proclaims the following findings. Firstly, terminology list can be an important knowledge base for discovering convergence technologies. Secondly, the analysis of a large quantity of literature requires text mining that facilitates the analysis by reducing the dimension of the data. The methodology we suggest here to process and analyze data is efficient to discover technologies with high possibility of interdisciplinary convergence.

This research purpose to improve the qualification items for electronic commerce manager. Former qualification system for the electronic commerce manager was executed 11 times from year 2000 to 2005. To improve the standard for test questions and contents of qualification items, we reviewed literatures about job analysis for electronic commerce manager, electronic commerce curriculum, e-Business market and other countries' similar qualification systems and items. We also analysed the job related knowledge, skill, and abilities using job analysis by DACUM method, subject matter experts interview and workshop committee for development and validation of qualification items. Based on the results of job analysis and DACUM workshop, we derived a job model for electronic commerce manager and then validated it through field survey and additional expert review. Finally we developed and suggested an alternated qualification items using matrix analysis between categorized job knowledge and job tasks.

This study aims to construct faceted navigation useful for domestic users through analyzing English and North American public libraries' faceted navigations. The 19 domestic libraries and the 12 foreign libraries has been chosen for analyzing their unique facets. Although the domestic libraries' facets had no differences to the domestic universities' facets, the North American libraries have their unique facets. Those facets are target audience, genre, library list, user tags, and availability related facets and the facets are mainly to improve user's usability in using library catalog. Adopting the facets in domestic public libraries by using Fixed-Length data elements of KORMARC, domestic public libraries will enhance usability of library users in retrieving library materials.

The purpose of this study is to verify the gain and loss of cataloging outsourcing in Korea public libraries. To this end, the following specific research questions are investigated: (1) How much has cataloging outsourcing enhanced the efficiency of cataloging operations? (2) What is an influence of cataloging outsourcing on the quality of catalogs? and finally, (3) Is there any evidence to strengthen core library service by outsourcing cataloging? The data needed for this study were collected from a survey with 3 public libraries which have experienced outsourcing. To make a comparative study, a survey with 3 public libraries against outsourcing are also included.

The purpose of this study is to improve the faceted navigation function of next-generation library catalogs(NGC) using the tables in a classification scheme. Because the tables provide forms or contents of materials systematically, faceted navigation based on the tables can be as effective as faceted navigation based on language, publishing date, or class-level subject facet. Therefore, class numbers based on the Korean Decimal Classification (KDC) were examined and the characteristics of schedules and tables were analyzed. As a result, suggestions to improve faceted navigation was provided. Moreover, the method using the tables does not need additional resources to derive facets because the facet analysis process is always carried out in the classification process.

In recent days, global shipbuilding companies have been showing great interest in eco-friendly ship products and trying to reduce environmental pollution - harmful gas and dust in shipbuilding process. Following this trend, Life Cycle Assessment (LCA) was carried out to an application of shipyards layout. LCA is a technique used to assess environmental impacts during the life cycle of products and systems. Until now, LCA has been used through ISO 14040 in somewhat limited industries, such as Building Life Cycle Assessment. Thus, this study analyzes the shipyard layout planning framework and builds life cycle inventory along with the simulation model structure to evaluate environmental impacts.

The purpose of this study is to analyze cases of several academic libraries, both in Korea and other countries, which have outsourced part or all of cataloging operations and examine current trends and controversy over outsourcing. Contrary to expectations of reduced expenses and increased efficiency in cataloging, outsourcing often results in bibliographic records of low quality which require additional costs to correct errors and maintain consistency and accuracy of records, and therefore, fails to reach the goal. Due to the absence of high quality bibliographic utilities, union catalogs, and authority databases, and lack of expertise in cataloging among outsourcing service providers, it seems that outsourcing is not currently an appropriate tactic for cataloging in academic libraries in Korea.

The purpose of this paper is to present core elements of bibliographic records to effective cataloging a variety of information materials such as monographs, non-book materials, serials, and internet resources. At first, AACR2R bibliographic data elements, the minimal level cataloging, and core records proposed by Progrma for Cooperative Cataloging(PCC) in Library of congress are discussed. After that elements of Core Records, dublin Core, KORMARC, and AACR2R are compared. Upon the results, this study suggests mandatory common core elements and optional core elements for cost-effective cataloging to all kinds of documents including internet resources.

This study aims to clearly understand 'Functional Requisite of Authority Data(FRAD)' being studied by IFLA focused on aspect of change from FRAR. In addition, it has established relationship between FRAD and concerned rules by analyzing effect of FRAD on RDA and MARC21 and reviewed cataloguing rules, format and situations of major authority DB implementations concerned about domestic authority controls in reflection of IFLA's activities for authority control. Based on the analysis, it has looked into considerations for domestic authority controls standards such as access control methods, expansion of application scope, introduction of new approaches such as entity-relationship model, reinforcement of roles for national bibliographic agency. These study results would be utilized as basic data for authority control.

The purpose of this study is to analyze the effects of the bestseller ranks on the book circulations in public libraries. To achieve this goal, the weekly data sets of 179 books' library circulation and bestseller list from January 1, 2018 to December 29, 2019 were constructed based on the data collected from BigData MarketC and YES24. Three methods for analyzing panel data including linear regression, fixed-effect, and random effect models were compared, and it turned out that fixed-effect model was better than other methods. The results show that the average ranks of bestsellers were associated with their public library circulations visually. Also, the analysis of fixed-effect model showed that the single rank decline of a book on the bestseller list decreases its average circulation of 0.108 while the size of effect varied depending on subject of books. The study empirically demonstrated the impact of a bestseller list on people's book circulation behavior, suggesting that public libraries need to reference sociocultural context as well as bestseller book lists to predict library user needs and to formulate collection development policy.
