This study was to develop KORMARC-bibliographic format reflecting cataloging trends after LRM using literature review, analysis of MARC 21 discussion papers, and comparison of the fields in MARC 21 and KORMARC. The acceptance and consideration of fields and sub-fields that need to be revised in KORMARC are as follows. First, in terms of LRM / RDA, fields 381 or 387 for the representative expression, field 881 and the change and addition of its sub-fields for the manifestation statement, and data provenance code to ▾7 sub-field for date provenance may be considered. Second, in terms of Linked Data, ▾1 sub-field for RWO, and field 758 for related work identifier can be added. Third, for the data exchange of KORMARC and BIBFRAME, it should be developed in consideration of mapping with BIBFRAME classes and attributes in KORMARC. Fourth, additional fields such as 251 version information, 334 mode of issuance, 335 expansion plan, 341 accessibility content, 348 format of notated music, 353 supplementary content characteristics, 532 accessibility note, 370 associated place, 385 audience characteristics, 386 creator/contributor characteristics, 388 time period of creation, 688 subject added entry-type of entity unspecified, 884 description conversion information, 885 matching information could be developed. This study will be used to revise KORMARC-bibliographic format and to build and utilize bibliographic data in domestic libraries.

Resource Description and Access(RDA) was published in 2008, reflecting IFLA IME ICC's International Cataloguing Principles(ICP), conceptual model for cataloging of Functional Requirement for Bibliographic Records(FRBR), and conceptual model for authority data of Functional Requirement for Authority Data(FRAD). Therefore, new tags and fields have been added to MARC21 format, and researches about the prototype have been studied to implement FRBR as envisioned by the new RDA standard. According to the innovative international cataloging environments, KCR and KORMARC must be revised to accommodate RDA description. This study was to grasp occurrence rate of work and expression element of FRBR and RDA among MARC field of Hansung University library and to analyze limitation of MARC data for RDA. Based on this limitations, cataloging rules and tags and fields of KORMARC were suggested to accommodate RDA in national cataloging environment. This study reviewed cataloging rules such like representation, main entry and rule of three, preferred title, types of content, media and carrier. This study is to suggest the consideration of KCR and KORMARC for RDA in Korea.

This study makes some suggestions to cluster works from the search result of library databases. Specifically, the author suggests modifying the current practices and rules of KORMARC 24X field based on intent of RDA, which is the new cataloging standard. After identifying some problems in entering bibliographic data into 24X field, the author proposes solutions to such problems. The solutions include improvements in (1) Goanje description (관제기술), (2) use of uniform title, and (3) processing of marks, etc. The study demonstrates that users can conduct a fronted keyword searching effectively and identify the relevant bibliographic records easily from the clustered search results.

The paper describes the development of a two-dimensional (2D) co-rotational nonlinear beam finite element that includes advanced path-following capabilities for detecting bifurcation instability in elasto-plasticity of steel elements subjected to fire without introducing imperfections. The advantage is twofold: i) no need to assume the magnitude of the imperfections and consequent reduction of the model complexity; ii) the presence of possible critical points is checked at each converged time step based on the actual load and stiffness distribution in the structure that is affected by the temperature field in the elements. In this way, the buckling modes at elevated temperature, that may be different from the ones at ambient temperature, can be properly taken into account. Moreover, an improved displacement predictor for estimating the displacement field allowed significant reduction of the computational cost. A co-rotational framework was exploited for describing the beam kinematic. In order to highlight the potential practical implications of the developed finite element, a parametric analysis was performed to investigate how the beam element compares both with the EN1993-1-2 buckling curve and with experimental tests on axially compressed steel members. Validation against experimental data and numerical outcomes obtained with commercial software is thoroughly described.

Shield method is the tunnel boring method that propels a steel cylinder in the ground and excavates tunnels at once. After Marc Isambard Brunel started using the method for the Thames Riverbed Tunnel excavation in London, many kinds of TBM (Tunnel Boring Machine) developed and applied for the construction of road, railway, electricity channel, pipeline, etc. In comparison with NATM concept that allows to observe ground condition and copes with difficulty. The machine selected before starting construction is not able to be changed during construction in shield TBM. Therefore the machine should be designed based on the ground survey result and experiment, so that the tunnel might be excavated effectively by controlling penetration speed, excavation depth and cutter head speed according to the ground condition change. This research was conducted to estimate penetration depth, excavate speed, wear of disc cutter on Boondang Railway of the Han Riverbed Tunnel ground condition by TBM performance prediction models such as NTNU, $Q_{TBM}$, Total Hardness, KICT-SNU and compare the estimated value with the field data. The estimation method is also used to analyze the reason of poor excavation efficiency at south bound tunnel.

The purpose of this study is to analyze the issues resulted from the process of grouping KORMARC records using FRBR WORK concept and to suggest a new method. The previous studies did not sufficiently address the criteria or processes for identifying representative authors of records and their derivatives. Therefore, our study focused on devising a method of identifying the representative author when there are multiple contributors in a work. The study developed a method of identifying representative authors using an author role dictionary constructed by extracting role-terms from the statement of responsibility field (245). We also designed another way to group records as a work by calculating similarity measures of authors and titles. The accuracy rate of WORK grouping was the highest when blank spaces, parentheses, and controling processes were removed from titles and the measured similarity rates of authors and titles were higher than 80 percent. This was an experiment study where we developed an author-role dictionary that can be utilized in selecting a representative author and measured the similarity rate of authors and titles in order to achieve effective WORK grouping of KORMARC records. The future study will attempt to devise a way to improve the similarity measure of titles, incorporate FRBR Group 1 entities such as expression, manifestation and item data into the algorithm, and a method of improving the algorithm by utilizing other forms of MARC data that are widely used in Korea.

This study is to suggest the concrete application plan of BIBFRAME under the development of BIBFRAME as library specific ontology for linked open data. The several research methods are used as the literature reviews, the case study of LC and LD4P, and the survey of cataloging librarians which is to grasp understanding level of the linked data related terms and requirements for constructing LOD. The application plan is suggested as follows. First, publishing name authority data and subject heading in LOD are prominent as the startup with creating terms list or vocabulary in LOD that has been used in library for controlled vocabulary and data value. Second, it is needed to develop BIBFRAME application and extension modeling in Korea, to map KORMARC and the properties and classes of BIBFRAME, and to develop the editor and MARC to BIBFRAME Transformation Tools. Third, the systematical training for cataloging librarians is designed to regard BIBFRAME related works as the librarian's main field. Therefore, this study would contribute to seek the practical application plan for BIBFRAME in Korea.

We report on development of a ground-based bi-axial Search-Coil Magnetometer (SCM) designed to measure time-varying magnetic fields associated with magnetosphere-ionosphere coupling processes. The instrument provides two-axis magnetic field wave vector data in the Ultra Low Frequency or ULF (1 mHz to 5 Hz) range. ULF waves are well known to play an important role in energy transport and loss in geospace. The SCM will primarily be used to observe generation and propagation of the subclass of ULF waves. The analog signals produced by the search-coil magnetic sensors are amplified and filtered over a specified frequency range via electronics. Data acquisition system digitizes data at 10 samples/s rate with 16-bit resolution. Test results show that the resolution of the magnetometer reaches $0.1pT/{\sqrt{Hz}}$ at 1 Hz, and demonstrate its satisfactory performance, detecting geomagnetic pulsations. This instrument is scheduled to be installed at the Korean Antarctic station, Jang Bogo, in the austral summer 2016-2017.
